Samsung :: U640 - Service Manual Or Guide To Replace LCD?
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.

Samsung :: Convoy U640 - USB Communications Overview
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.

Samsung :: SCH-U640 Convoy Get Pics To PC Via Cable
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.

Samsung :: Convoy SCH-U640 - Way To Keep Speaker Off When BlueTooth Is Connected?
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.

Samsung :: Convoy (SCH-U640): BitPim Setup Assistance?
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)

Motorola :: Service Manual Through Dealer?
Does one have to go through an authorized Motorola dealer to purchase a service manual? I called Motorola today to purchase one, but there seems to be no "parts" department to talk to, or a cellphone service department. I'd like to get a service manual for the V8 so I can get the exact part numbers I need for my project. By the way, I have searched all over the web, including file hosting websites like 4shared.com and came up with nothing. All I found was the service manual for the V9.

Sony Ericsson :: W800i - Repair / Service Manual
I've been looking all over the web for a service manual for my W800i but I can only find one for a K750i, and yes I know it's almost the same phone but almost isn't good enough.

(I've already tried google and been through like 20 result pages!)

HTC :: Touch Diamond (Telus) Service Manual Or Disassembly Instructions?
The internal speaker is intermittently cutting out on my HTC Touch Diamond from Telus and I'd like to open it up to check the connections and replace the speaker if necessary. However it's more difficult than I thought to take it apart without breaking something. The Touch Diamond service manual on the XDA Developers site is only for the US version of the device, not the Telus version, so the instructions are completely different.
Does anyone have the Telus Touch Diamond service manual, or a link to specific instructions for the disassembly of the Telus Touch Diamond?

Samsung :: D807 Disassembly Guide
so after about 2000 useless posts on the forum, I decided its time for something useful. I got this d807 with a broken screen (As do many other people) and seeing there is no guide on the net as to how to take it apart, I decided I'll make one myself .Just so nobody gets pissed off after they wreck their phone, this method worked for me. I do not guarantee it will work for you, any damage to your phone resulting from this is your own responsibilty. That being said I took my phone apart twice without any damage.Alright to start off here is what I used:Screwdrivers, cellphone opening tool and my hand
