Samsung :: U640 - Service Manual Or Guide To Replace LCD?
Aug 24, 2010
Does anyone know of a service manual or guide to replace the LCD screen on a Samsung SCH-U640? I cannot seem to figure out how to disassemble the display portion. Also, any parts source would be helpful as well.
For those interested in accessing their Samsung Convoy (SCH-U640) via the USB cable from their Windows computer, here are some insights not apparent in the Users Manual. (I use XP).
The phone distinguishes three modes of communication via USB with a computer: 1. USB Mass Storage (Menu/9/2/8) 2. USB Media Sync, and 3. USB Modem. The last two are chosen by a setting at Menu/9/9.
1. USB Mass Storage Mode (also see Users Manual pg. 138) USB Mass Storage mode allows access to the external (microSD card, if installed) memory through Windows Explorer. No phone-specific USB drivers are required for this connection. You have some limited control over which files or folders are stored on the card. This is managed at Menu/9/8/1 or from a screen appearing at insertion of a card. None of the phone’s “built-in” files are moved to the card. Certain copy-protected files also cannot be moved to the card. For instance, none of the built-in ringtones or built-in pictures is present. Although it is possible to move your contacts to the card (Menu/9/8/2/7/Options/3/MarkAll/Done/Yes/OK), the phone is unaware of contacts on the card. Therefore “copying” contacts to the card can be useful for backup purposes, but if you “move” contacts to the card then the phone will show no contacts. (Note that pictures, including any associated with contacts, are managed separately and may be stored on the card or in the internal memory, your choice). It appears that in USB Mass Storage mode one can add contacts one at a time or en mass by copying contact vcf files from the computer to the my_contacts directory. Then, with the phone disconnected from the computer, move the new contacts to the internal phone memory (Menu/9/8/3/7/Options/3/MarkAll/Done/Yes/OK). I am not knowledgeable on what restrictions, if any, apply to vcf files acceptable to the phone. If you have inserted a microSD card and wish to upload pictures to your phone for use as contacts photos, then you can use the following format: jpeg, 72 dpi, 1600 or less (wide) x 1200 (high). In USB Mass Storage mode copy the pictures into the my_pix folder.
2. USB Media Sync Mode (also see Users Manual pg. 126) USB Media Sync mode allows the computer, running VCast Music with Rhapsody, to manage music files on the phone. Installation is a two-step affair. First one installs a phone-specific USB driver (say from http://www.vzam.net/vcastmusic/Step2...nufacturerID=4 ). The Convoy (sch-U640) is not listed in that drivers table, so I chose the sch-U620 driver. The driver installer appears to be the same for many of the Samsung phones. With the USB driver installed, next one installs VCAST with Rhapsody. Note: actually, the phone connects fine in USB Media Sync mode without the USB driver, and VCAST works, but one gets annoying “Found New Hardware” messages from Windows at connection and disconnection. One can access the device memory, in part, in Windows Explorer when the phone is connected to the computer in USB Media Sync mode. Only two music-related folders appear (Music, Playlist), and the Music folder is sorted into performer/album/ subfolders unlike when viewed in USB Mass Storage mode. Whether one sees internal or external memory depends on where the phone is storing music files. Note: When one explores the phone without loading the USB driver, a third folder, “Albums” appears. Note: It is apparently not possible, or at least not obvious how, to upload calendar items to the Convoy from the computer (say from Outlook) via the USB connection. This can be done, one item at a time, via Bluetooth (Users Manual pg. 93). Note: the USB driver obtained here is not compatible with the software program BitPim, which does not find the phone at all in USB Mass Storage or USB Media Sync mode. But see below!
3. USB Modem Mode This mode of communication is designed to use the phone as a USB modem to connect a computer to the internet via the cellphone network. For that purpose one must first install VZAccess Manager. The USB Modem mode, established at Menu 9/9 followed by plugging in the cable, does not cause the device to display any entry in Windows Explorer. Note: Whether or not VZAccess Manager is installed on the computer, the USB Modem connection allows BitPim to interact with the Convoy. BitPim has not evaluated the Convoy, but several of the program’s features work when one manually selects the SCH-U750 (Alias 2) phone. However, I have not tried to write from BitPim to the phone.
I'm not sure if this has already discussed, but I could find no information on it through google searches or on these forums. How to download your pics from your Convoy SCH-U640 to your PC. 1. Gotta have a microSD card. 2. Your pics need to be on the card. You can set the phone to automatically save to the card, or you can move the pics to the card using the options menu in your "My Pictures" section. 3. Plug the phone into the computer using the data/charge USB cable 4. If the phone wants to sync just hit "End." 5. Open Menu/Settings & Tools/Tools/USB Mass Storage 6. Viola, you can browse the contents of your microSD and remove the pics. My mistake was I was looking in Menu/Settings & Tools/USB Mode to try and get the pics from the card. This activates the Sync mode, which is only for music, not pics.
My wife can not believe that the phone rings through the Phones speaker even if she is listening to music through her BlueTooth headset(s). This happens with several BlueTooth devices, so it must be either a function of the phone, or a setting she has not found yet.
The problem is that if she is in a public area listening to music on the BlueTooth, and a call comes in, it transfers to the Phones speaker and disturbs everyone. I would think that if the phone was connected to BlueTooth, it would know enough to keep the speaker OFF. Is this normal for his phone? She uses a Motorola S9-HD headset, or a Plantronics Voyager Pro or a BlueAnt Supertooth 3. This happens no matter which device she is using.
I have the convoy...i have win7 (32-bit, starter) installed...PC seems to recognize the phone alright. downloaded the modem drivers...everything on that end is cool. I found several threads with much discussion on the topic...but none of the sets of directions have seemed to work.
According to my understanding, I'm supposed to select the modem diagnostic serial port as my target port...unfortunately though, BitPim has read that port as unavailable. The one time that it was listed under the "available" part, it still didn't work. When it seems everything is set correctly, it's giving me a "could not open port" error...port settings are correct.
What else can I try? are there any other methods (w/o using illegally distributed software) that I can use? I've been fiddling with this thing for about 5 hours now....and i wish it wasn't so dadgum complicated. It's my phone, and lets me download music to it...but no ringtones??? come on. (/endrant)
So I got this phone today. Loving it so far except that the email seems to want to sync every few minutes. I don't want it to use all my data. How to I set it up for manual sync? Every other phone I've ever used has this option....
I was hoping we could setup this little thread to fill each other in on tips and tricks that aren't covered in the manual. For example, when I have my alarm set and set on alarm only for ringer, the alarm is so freaking loud it gives me a heart attack in the morning. Is there any way to turn it down before I set it? Since the ringer is set for alarm only I can not control the volume that way. Just wondering if there was a way to make it softer. Also, when its powered on and charging is there any way to get rid of the annoying little beep when it becomes fully charged? Hearing that at 2AM isn't fun. Again, I have the phone set to Alarm only and it still does that.
After having problems with me phone and my in car stereo, via bluetooth, i would like to know if it is possible to replace the Bluetooth software that comes with ICS with the version that comes with GB.
Can someone please let me know what the process is for entering the service menus for the above phone? I need to review my wap settings and I cannot find info anywhere on the web on how to do this for this phone.
need some help with this samsung slash sph-m310 phone.I bought the Samsung 20pin data cable, but WinXP won't recognize the phone. Searched for USB drivers for this phone and downloaded some software from Samsung called Samung PC Studio 3, also tried studio 2. They had usb drivers but doesn't look like any of them helped.Then I was looking in the forums here http://www.howardforums.com/showthread.php?t=1434738 and saw someone said to type ##7678# and enter V-I-R-G-I-N into the phone, that there was a data screen to allow data transfers. I did enter this into my phone, but nothing happened. Wrong code it said. Tried some other numbers eventually the phone just rebooted and then shut off. Was worried i locked the phone, I hit end and the phone works fine now. whew!So please help, what is this screen ##7678# on my phone? And did I screw it up? and is there a usb driver for the m310 phone?
I have a S2 with 2.3.3 installed. I did upgrade previously using Kies. I now want to connect the phone to Kies, but it does not work properly.I connect the phone to the PC and it is detected by Windows. I can even browse the files in Windows Explorer. When I start Kies, it just says "Connecting..." but fails after a while with error "Can not start service on device". The phone screens shows that I am connected to Kies.
I had problem with low volume during the call so I followed the suggestion in the forum elowhttp://www.samsunggalaxysforum.com/s...)-very-low-!!/There are suggestions to adjust the "sidetone" value. Once I did that, I have been hearing the echo throughout my calls (not happen in speaker or headset mode, though). Now I am very frustrated. If anyone come across the solution for this issue
I need a quick and easy guide to root my 0.62 GB version of neo v.Pls let me know if this is for 0.42 version or 0.62 version.And also without unlocking bootloader.i haves a lock bootloader and dont want to unlock it.
Bought a Nokia N97 Mini Gold Edition yesterday. There is no user guide in Arabic in the box. Come on seriously guys. You are selling a product in the middle east and the least you can do is provide an arabic guide along with it. Called up Nokia care, they ask you to call Axiom, call Axiom and they ask you to call Nokia. Gave up the hope. Tried to get a user guide from the Nokia support website. Go to http://www.nokia.ae/support-en/support-en/n97-mini/guides and select Arabic and the page comes back with an HTTP 404 Not Found.
Imagine buying a phone worth 2500 AED and you don't have a user guide to go with that. Imagine calling up Axiom and Nokia care line just to hear that there is no guide provided in Arabic with the phone. Imagine you feel like an idiot buying something that does not make you happy. Now imagine if that someone were to be you.
It seems that there are a few out there struggling to make the Nokia N97 (and other S60 5.0 devices) work with VoIP (SIP), so if you're one of those folks scratching your heads wondering how it's done, then take a look at this guide with screenshots:
I used my Gizmo account details as an example for the settings, but of course you can substitute any SIP VoIP service provider's settings there instead. I understand that the guide won't fix everyone's problems, but any feedback to this discussion thread is welcome and with that we could improve the guide.
In other new S60 3.2.3 devices such as the E52 or E75, you will find the settings to be slightly different, but the basic setup procedure is similar. For those having even older devices like S60 3.1 (e.g. Nokia E71), there's a slightly older guide here:
It's been a while since I've logged into the forums. Since I've only been lurking for advice for ages, I figure it's time I actually gave something back. Below, a few notes on my journey into factory unlocked iPhone land.So about a year ago, I bought a 'new' iPhone 2G off eBay to replace one I had stolen a couple months earlier. Unlike my original 2G, this one got knocked around quite a bit, including several drops on concrete and tile. The screen was, mercifully, okay, but the home button was hard to press, the vibrate function was off-and-on, and the phone was getting bogged down by OS 3.1 besides. Once I heard about OS 4, and how I wouldn't be able to get it on my old phone, I decided it was time for a new one. WHY UNLOCK? So why even bother unlocking? Well, for one, I've been buying and software-unlocking my phones because I loathe AT&T's coverage, and am enjoying a T-Mobile plan at about 30% off the equivalent AT&T price. Considering 3G is spotty wherever I am, and I have wi-fi in most places I hang out anyway, I'm willing to live with EDGE.
The jailbreak feature is really handy, too, because I'm a stats nut who loves scrobbling to last.fm. There is (and for the foreseeable future, will be) no background scrobbler to send my recent tracks to last.fm without a Cydia app. But I digress…
I finally got fed up with the cat-and-mouse game, constantly worrying about bricking my phone, and enduring the performance issues I have been since 3.1+unlock. Note the difference: a software unlocked phone means you can buy a (cheaper) locked phone, but you have to wait for the most excellent iPhone Dev Team to deliver a version of Pwnage before you can upgrade. Plus, I noticed a lot of performance issues with my older iPhone. A factory unlocked phone was never locked by a carrier, and really does mean any SIM, any time, anywhere--NO QUESTIONS. But where to get one?
BUYING This is the tricky part. You basically have three choices to get a "legally" (factory) unlocked phone:Buy one for $850+ on a reputable site like Buy.com, TigerDirect, or a host of US and UK sites. Give a friend going to one of a number of unlocked-iPhone countries a bunch of money to buy an unlocked phone for you. Buy one for $600+ on eBay.I opted for option 1. How do US/UK companies get these phones, when there are no unlocked carriers in either country? Essentially, they're surplus phones being bought up by wholesalers and then sold to big computer parts companies like TigerDirect. My phone actually carries a Hong Kong part number, but there were no other markings (print, instructions, etc.) for me to tell the difference.** EDIT: Jersey in the UK's Channel Islands also sell the phones unlocked. Probably a spendy trip for US customers, though. phones are definitely expensive: $700 for an 8GB iPhone 3G all the way to as much as $1300 for a 32GB iPhone 3GS. I got mine for a little over $800 thanks to a Buy.com error (which they and Tiger Direct honored, much to my surprise!).Option 2 is cool, if you have a trustworthy friend.Option 3 can be dangerous. A lot of sellers will try to blur the line between software unlocked phones (using the very awesome iPhone Dev Team's unlocking software) and factory unlocked phones (which were never locked in the first place). BE AWARE OF WHAT YOU'RE BUYING. Ask for the part number. Google it, and if it's legit, you should see multiple search results online linking the part # of the iPhone you want to buy with a country with unlocked iPhones. If not, don't fall for the scam. It might be a software unlocked phone, which is definitely not worth the $600+ you'll be paying. Or it could be an iKnockoff, which is just a jerk move all around. UNLOCKING hen I was doing research, I read some conflicting info on this one. But rest assured: IF YOUR PHONE IS LEGIT FACTORY UNLOCKED, YOU DON'T NEED TO WORRY ABOUT ANY EXTRA PRECAUTIONS. PERIOD. Just insert a SIM card, plug it into iTunes, and it'll register and activate the phone just as if you had a normal AT&T account (or whatever your national iPhone carrier is). That's it. It doesn't matter what country you're in when you unlock, nor does it matter which country's iTunes Store you're registered with, nor does it matter what country your part # is associated with. Just plug in your phone and go. If you're having problems, it might be a phone issue, or you might not actually have a clean, factory unlocked phone. HOWEVER, if you jailbreak after that, it's just as if you'd jailbroken a normal, clean iPhone, and all the normal precautions apply.
CONCLUSION So that's my primer on factory unlocked iPhones. We iPhone users are now conditioned to fear any unlock, but the factory unlocked phones appear to be a lot less scary than they're made out to be. The biggest concern you should have is that you're getting a legit phone from a legit seller—if you're paying several car payments' worth to buy a phone, be careful! Any questions? PS--I'm getting ready to sell the old 2G. I'd like to leave it unlocked, but still wipe all my data off of it. Anyone know the best way to do that? PM me with answers.
All of these new features are great but does anyone know where to find a User Guide to show how to engage/use them? Not even Apple.com has anything listed.I stumbled on how to create folders in another thread. It would be nice if all of the info was in a doc somewhere - it'd be a timesaver for me (and I can't be the only one.
So i've had an iPhone since they came out way back in 07. I've always had the black one since you had an option of colors. Recently i began to wish my iPhone was white. What are my options? Buy a new one right? I use my iPhone on tmobile, so no upgrades for me, I would have to buy one outright. I plan on getting a new one when/if a new one comes out this summer. I did some googling and found you can buy just the back housing of the iPhone. So i bought it, and set it up. You need 3 things...

I also bought an incipio feather case in white. I've never had a case on my iPhone bc i don't like how thick they make it feel(This is also why it looks like complete crap).

Its still over 2 weeks before the iPad Launches and we already have a solution Very Simple really here is what you need.
1. First you will need a jailbroken iPhone, check jailbreakmatrix.com on howto jailbreak your device 2. You will need to install the Rock Installer when you jailbreak 3. Second head over to Rock Your Phone and sign up for a free account 4. Install MyWi with Rock and start it up
Here you create your Wifi Name, Password and Encryption and then goto your iPad and join the Wifi Connection, No jailbreak no software no nothing required on the iPad
We are located in Canada and know that the iPad 3G is coming with micro Sims which you can't get here yet so don't waste that 6gb data plan you have, and lets put it to use. This way you can also grab it on April 3rd when it launches and don't have to wait for the iPad data plans to be released from the carriers?
I have just this morning got my nokia n900, second hand from ebay. before i put any files on there i want to restore it completely, but this flashing thing is really confusing me. I've done a search of the boards but it baffles me, so if anyone could answer these questions it'd be really helpful:
1) how do i completely wipe it as though it were brand new? (not 'restore original settings' in settings menu, i mean the equivelant of a hard reset)
2) how do i determine what firmware i'm on?
3) what is 'flashing'? is it necessary? if i connect my phone to pc suite/NSU to check for updates, will it work as it does on S60 eg nokia 5800, or do i need another method?
4) i gather the latest firmware isn't yet available for the UK. how do i go about installing it given the n900 doesn't require a changed product code like other models?
