I have a Samsung Jack I am selling and I did a Master Clear and Master Rest.I unlocked the phone prior to the Master rest/clear. Now that I did the Master reset/clear does the undo the subsidy unlock code? Meaning does someone need to re-enter the unlock code again to "unlock" it?

I set a screen lock code today and used it several time with no problems. Tonight the unlock screen shows 'Enter Password to Unlock' but when I enter the pin code, it will not unlock.

Ive got a new Galaxy S2 and after using it for a few days I now have a voice telling the weather and the time on the screen everytime I unlock the phone. What did I press to get it and how do I delete or mute it? I have not dowloaded any new apps. I only have the ones on the phone so far.

Just got a samsung galaxy s2 earlier today. Unfortunately, it is locked to the O2 network and I need it on the orange network.Learning via google, I have rooted the phone, and tried the 'Galaxy S2 sim unlock' application to find the unlock code but it came back with the following message 'cannot find unlock code' Just wondering is there something I have done wrong? Also have an annoying yellow triangle with an exclamation mark that comes up every time the phone is rebooted.

my brother has an S2 with out-of-the-box, custom ROM, not ever flashed or rooted, etc. He has just been told he has to work in Spain for the forseeable futre but wants to come home at weekends. He also wants to keep his S2.
If he roots and flashes his phone, will he be able to buy a Spanish SIM from any Spanish network for use in Spain, and just replace it with his own SIM when he comes back here? In other words, does a root and flash of a phone make it fully internationally unlocked so that he doesn't get any extra charges from either Spanish or UK networks?

i have recently changed from O2 to three and taken my number with me. I have requested, and received an unlock code for my S2, which I plan to sell, however, the instructions say: "Insert another network active sim in the handset. This should ask for a code. Input 8 digit unlock code when requested." But when I try another active sim, (I have tried both Three and Orange), it does not ask for a code

I got a used samsung 5 phone from tmobile because my original one broke. After a few hours, the phone became very slow and sometimes unresponsive. I tried to do a reset but then a warning came up, saying how the phone is a custom os and resetting it might cause damages to the phone. Is there another way to solve the lag on my phone or do I still proceed with the reset?

I always use my fingerprint as a password but for some reason that option has dissapeared and the only thing on the screen is the option to put it a password or emergency call. I don't remember my password and can't get in, i've tried restarting my phone, turning it on and off, and taking the battery out but its still like this.

I am not very well versed in computerspeak , and have never had to back up anything on my phone. I am having no luck in diagnosing a problem with my bluetooth(won't turn on) , Samsung has suggested doing a Hard re set ,in hopes of fixing the problem. I would like to back up ALL of my data , contacts , apps , texts , etc. , but have no idea on how to go about it. I did a search here and became even more confused ! Will I be backing up to a pc , if so will I need a physical connection , will I backup with KIEs , and again , how is this done , and what , if any apps should I get to make my life easier , by the way after this , I want to update the OS as I am using gingerbread.

I accidently deleted the full contents of the "Camera" folder.ll the photos and video that I had taken in the last 2 months were lost. ( I know I should have backed them up...but I was planning to do it today...not thinking I was going to do something stupid last night!)I have a hunch that the files might be able to be restored...possibly using some sort of restore/recovery software.I have tried 2 software programs so far...Piriform Recuva & Stella Phoenix Photo Recovery.he problem is that neither of them recognise the Samsung Galaxy S II as being present, even though it is plugged in and showing in "My Computer"So...does anyone know of software that does work.

my SGSII losing its capability of using 2/3G networks - (i.e. no green and red arrows). I can connect to wireless networks but that's it, which is pretty frustrating when I'm out and about in town, out of range of wifi, and want to check something on the Internet, etc.So now I'm faced with the unwelcome prospect of sending my phone back to Vodafone to get repaired which means 10 working days without my phon? would flashing my SGSII bring back my 2/3G capability? If this was the case, then I'd obviously do it, and be saved from sending my phone away for 2 weeks. Currently I am on Stock ROM, 2.3.3?

I thought I'd start a new thread to prevent going too far off topic on another thread that I asked this question on."If you want to go down that path you are better to root, unlock (via the market app) and then flash the XEU to your branded phone, and it will debrand it.It's all in a sticky on the Development link.EDIT: I've been using this root method and works well.For me downloading this file worked best and selected he 'touch' option http://clockworkmod.com/rommanagerTo avoid confusion it's this download: 5.8.1.5"Completed the above as advised by greenman and am now rooted (superuser installed and rooted apps work OK), but when trying apps to unlock phone I get no luck. Messages like "No code found etc from 2 apps I tried.

I recently upgraded from Gingerbread to ICS and had battery life and overheating issues. I was told by Samsung to do a drain the battery, recharge to 100% and then to a factory reset. I followed these instructions, but now I get the following message on my screen: "Unfortunately, twlauncher has stopped"I can no longer use the phone or reinstall my data from KIES (Kies does not even recognize that my phone is connected). I have tried to reboot in Safe Mode and do a factory reset, wipe cache, and reboot from there, but i still get the same error message about the stopped twlauncher. my phone is unlocked (International European version GT-i9100) and was rooted using SU-Busybox and Recovery Clockwork Touch.

My husband and I have each had an S2 w/T-Mobile for roughly five months. Several days ago his started restarting on its own any time the screen was turned off (either manually turned off by tapping the "power" button or when the screen timed out) but no other time. It was doing this for a couple of days. I contacted tech support and they suggested a factory reset, which I did. It came back online with no trouble, and he was able to log in to his accounts, make calls, send texts, etc. It didn't restart on its own at all for the couple of hours we had it with us that night. During those couple of hours it was plugged in to charge. We went to bed and the next morning it was completely dead. No response to any buttons, doesn't acknowledge when it's plugged in, nothing. We tried swapping batteries and SIM cards with my phone, and still nothing.
