[Q] Phone's network lock returns after update - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I've been a happy CM user for over a year now - rooted and flashed ROM's in the first week that I got my GS2. I also used Chainfire's SIM unlock in the process.
For the last 2 months I have been updating to the latest nightly of CM10 without any problems, just this last week I did my usual update and upon reboot I was greeted with a "Network SIM Unlock" screen. I thought it might just be a bug in the nightly, pressed dismiss and rolled back to the previous nightly but the problem persisted. I went as far as to flash CM7 but the problem has followed me there too.
I've tried using chainfire's SIM unlock again, but it couldn't find the code. I've also tried an app called GS_II repair with no luck. Tried factory reset's, cache clearing and different kernels, all to no avail.
Anybody have any ideas what the problem is / how to fix it?
Any help would be highly appreciated!

search on google play GalaxSIM Unlock from Spocky,it's free,but when you will push the unlock button you have to pay like 2 euro.I buy my phone with 4.0.3 and when i upgraded to 4.1.2 i lost the unlock...with this app i unlock my device and since then i flash a lot of roms,it's great an cheap :good:

Thanks for the pointer - not sure if I want to spend money on an app that doesn't guarantee a fix...

"highly appreciated".......bollocks-you didnt even hit the thanks button when that guy helped you.Dont want to spend money-then keep the lock on......lol.
And if you bothered to search, you will find out that if you read Spockys thread on xda, you can download his app and use it for free.
Also there is an option to donate to him as a thanks for his work, in helping out ungrateful cheap skate nerks that didnt buy a ....in unbranded phone to begin with.

[Q] Help please, unlock S2 currently on Orange UK

I was given a new S2 on Orange (running ICS) which I didn't want or need, so I sold it. The person who bought it said she wanted an unlocked phone to use on another network and I told her she could get this phone unlocked, either for free, if she googled it (using a couple of apps that root then unlock) or from most phone shops. She bought it on that proviso.
I received a call from her today - she is complaining that she tried the "free" way - which didn't work, then tried a number of phone shops, every one of which said that the phone couldn't be unlocked.
She may have done the "free" way incorrectly therefore making it impossible for the phone to now be unlocked. I feel somewhat responsible but don't want to take back the phone now. I said I would call in to try to help her when I'm next in her area. Is there anything I can do to get the phone unlocked now?
Any help and advice would be very welcome and thank you in advance.
I doubt there is anything that can be done and the assistance you are asking may not be forthcoming from this forum.

Whoever tries to unlock the phone will need some basic knowledge in this area and needs to understand all the risks associated with this process. If you can tick off these two boxes just follow a few simple steps (just done that myself and can confirm it works fine):
1. Root your GS2 (plenty of threads on this forum)
2. Go to Google Play and search for "Galaxy S Unlock", the author is "Helroz".
3. Run the app from step 2. Go to "Unlock SGSII" tab on the top of the screen.
4. Tap on the first item:"Step 1 Backup files...."
5. Tap on the second item:"Step 2 Change lock-bytes", and wait until your phone restarts.
That's it.
No chance. If mobile repair shops can't unlock it, no way anything from Google Play (or anywhere else, Unlock SGSII included) will unlock it. Somebody is paying for an unlock code from a carrier.
u mite wanna chk dese links

This is the way to do it. It works because i did it this way 2 months ago on my orange uk I9100P last week on my draughts new I9100P. You might have to update your bussybox that's all
Sent from my GT-I9100 using xda premium
Many thanks to everyone for their inputs, I really appreciate it. I'll be trying today/tomorrow to sort it and will update with result.
Cheers everyone.
All done successfully - many thanks to all who replied to my plea for help.
i am having samsung galaxy s2 I9100 .i brought it second hand.i dont know that it is not factory unlocked.now i flashed my s2 to leaked XXLSJ 4.2.1.now my device is asking for sim card unlock code.what should i do.....plzzzz help
OK first time in this forum, (so please be kind!!)
I'm not a total newbie to android - Google Nexus One - CM7.2 and SGS CM9.
Currently :
S2 GT-i9100P
Android 4.0.4
Baseband - I9100PBVLPB
Kernel - 3.0.15-I9100BULPC-CL332484
Build no. IMM76D.BVLPC
Was originally running 2.3.6 GB but updated via KIES to 4.0.4
Rooted with CF-Root
Yes, I have backed up my efs file
Yes. I have the dodgy emmc chip
NO!! Not bothered with NFC as probably gonna go CM10 when succesfully unlocked.
I've tried all the unlocking routes, free and paid (still waiting for several refunds!!). "Helroz" works, but if phone is restarted, have
to run app again to get unlock.
Does anyone have a permanent fix?
If it were for me, then no problem running Helroz every time, but it's for my daughter so want something permanent.
Going to go to a "phone shop" tomorrow to see what they can do....But much prefer to get it sorterd here with people that know and care!!
Thanks in advance
OK After MORE searching, finally found the thread for "GalaxySim Unlock 1.02" Duly downloaded and works a treat. I have thanked in that thread.

A couple of questions

Hello, I just recently got an Atrix off of ebay. I want to get into playing witih android phones. I've already read numerous threads, got the android sdk, rsd lite, etc.. I've been reading about flashing, and to be careful of what you flash based on what firmware versions are already on the phone.
The problem I have is the phone is subsidy locked, but it's locked in a way that not even AT&T sims work. It always asks for the pin, and the code AT&T gave me (they stated it was the subsidy unlock code) fails. So I looked at
http://forum.xda-developers.com/showthread.php?t=1356121
However, I have no idea what's on this phone. I can't access any settings menu in the phone, as it sticks to the "Emergency Calls Only" screen. i don't know what firmware is on the phone, what radio is on it, etc.. I don't want to try to flash a radio file and have it brick my phone. I've read quite a bit this past hour, but I'm at a crossroads here and don't know what to do to figure out what is exactly on this phone. If I knew what I had exactly, I'd be a lot more confident in flashing things.
I do know the bootloader is unlocked (the phone boots saying "Unlocked"). That's all I know :\
EDIT: Disregard. It took me another 6 hours but I finally got everything figured out (had to boot it with no sim to view things, then from there I got into it all). Rooted, CWM, flashed the bell radio and my sim works for now. Thanks for the valuable info that's listed here!
Any help will be highly appreciated. Thanks!
hey,
I do have the atrix which is netwoek subsidy locked.
I even cant use at&t. I am outside us currently.
Could you tell me how did you flashed bell radio & where u got that.
Thanks

[Q] sim network unlock pin

Hello everyone, this is my first post here and I am in need of desperate help.
I have looked everywhere I could but (my bad) I am not into all this stuff at all. I am not familiar with ROMs Kernels etc. I just follow tutorials blindly.
I have a galaxy s2 bought which I bought in the UK. It was locked on 3 network. Later I moved to another country where I got it unlocked for about $35 but that still showed signs of 3 network (The 3 startup logo, 3 bookmarks in web browser etc), however the phone was unlocked now and picked up any network I used.
I noticed the phone stopped giving me any kind of updates and it was on andriod 2.0.1.
I looked up the internet on how to install latest updates for my phone.
Found out this guide and went thorough all the process: goo.gl/yJSga8
Everything went fine but when the phone booted up, it asked me to enter "sim network unlock pin" and now all networks are inaccessible.
I am pretty much stuck at this point. Found guides telling to root the phone and then installing apps like Galaxy S2 SIM Unlock by Chainfire.
I have tried it once and was near to kill my phone. (The yellow triangle appeared at startup and got stuck there. No boot.) I just re-flashed the firmware by following the first guide again and now the phone is like before asking for sim network unlock pin.
I have attached the screenshot of the info that you might need.
I am willing to pay $15 via PayPal if anyone can help me out to fix this issue. (I am a bit hesitant using the rooting method as I an afraid I might kill my phone. But if that's the only choice then I will go with it)
Please ignore if I sound really stupid as I really don't know about this stuff. Please ask me any details that I may have missed out.
Thank you very much!
Attached Info Screenshot
If you don't want to root, then you'll have to call your carrier and ask for an unlock code. Mine has that service at least, don't know about all carriers.
As far as solving your problem goes if your carrier won't help out... The thing that works for a lot of members here is to root, then use galaxsim unlock app, by xda member spocky12. Search for the thread.
That app requires root access... To do that, easy way is to flash philz kernel from recovery mode. Search up philz kernel thread here on xda and read up how to flash it
Sent from a galaxy far, far away
Hello hopper, thanks for the response.
I took your first suggestion but instead of calling the company itself I used an online service unlockliberty.com.
They charged me $20 via PayPal and almost instantly sent a code to my email address.
I entered the code on the phone but it gave me "Network unlock request unsuccessful" error.
Contacted support and they sent me a defreeze code and instructed me to restart, enter the defreeze code instead of the unlock code and then it will say "Network unlock request unsuccessful" and after that enter the unlock code. I did the steps and it worked like a charm! my phone is now unlocked.
I really recommend their services if you are in a similar situation.
Thanks alot!

[Q] Needing to unlock again!!?

I got my phone on ebay.co.uk sometime back then. A small orange logo is branded on the backside. The least I did was to root and sim/network unlock it. Apps piled up over time and it was getting laggy. I had to install an android version. Through many hours of following instructions, waiting, trying a few versions and being frustrated. I finally got to android 4.3.1. However I had to root and sim unlock it again! The 2 popular method - galaxy s2 unlock, and galaxy S unlock with busybox, both failed, and to no avail even after reinstalling the android again. The phone was still sim locked.
So fed up I put it aside for. Today I upgraded to 4.4 and both unlocking apps failed. I restored it to 4.3.1 hoping I can get some help over this mess.

[Q] Is there an alternative to the Asus UnLock Device App?

I was just given a tf201 in excellent condition, running stock Jelly Bean 4.1.1.
I have it rooted; but, also want to unlock the bootloader, so I can put a better ROM on it.
Every video or forum thread I have found says to use the Asus UnLock Device App v6.
A few threads say that it now only supports ICS; and, that may be the root of my problem:
Despite following every recommended step for installation and unlock, the Unlock Device App will not recognize my Google Password (a requirement). I do not use 2-step authentication, I went into Google Settings, and changed "Allow less secure apps" to 'ON'. I even changed my password, deleted/recreated my account in the tablet. Despite all of this, the Unlock Device App will not accept my Google Password...and, won't unlock the Transformer Prime.
Does anyone know of an alternative method to unlock the tablet; or, or a 'fix' for my Google Password issue?
Thanks, in advance!

EDIT: Everything I've read says the unlock tool is the only option. The serial number on the device apparently gets checked against a database in the Asus China servers, which unlocks encryption so the bootloader can be unlocked.
I had a similar experience when I unlocked my Prime last weekend. I can't remember exactly what I did to get it to work, but it finally did work for me after I tried different things. The device is on firmware 4.1.1 JB/ 10.4.2.18.... so it definitely does work on JellyBean.
I didn't have 2 step verification activated either, but if I recall I had the issue where Google was not allowing less secure apps. Since you allowed that.... I'm not sure why it's not completing the process for you. I think I had received some sort of notification on the Tablet after typing in my Google password... and I had to confirm the notification to allow the app to have full account access.... but I honestly can't remember. I do remember looking through all the troubleshooting tips here: ( https://support.google.com/accounts/answer/6010255?hl=en ) and here ( https://support.google.com/accounts/answer/6009563 ).
I also remember using ES File explorer to see if there were any leftover files from the unlocking attempt, and I remember seeing a text file named "Unlock" or something like that, which I believe the app had created. (I've got to head out the door to get to work in a moment, so don't have time to look for it again right now)... but see if you can find that file and delete it... then try wiping data and cache in the Manage App settings, reboot the phone, and try to run it again.
The process was a pain in the butt for me too, but it finally worked, so hopefully you can get it to work for you too.
Thanks! Was given a really simple solution at another forum: Factory Reset/DO NOT register any Google account/use the UnLock Device App v6.
Worked like a charm.

Options for not Unlocked device
Hi,
I tried multiple times to unlock the bootloader in the last 2 years (unsuccessfully), then few days ago I contacted Asus and they replied to me that "The unlock tool has been discontinued since 2014", so no way to unlock.
What are my options now? No way to install new roms, but there is any known method for at least rooting the device (with the latest firmware)?
Thing is, that I really liked the transfomer (especially the keyboard) but it's always been too slow to browse the internet, and actually there is no replacement I can buy (asus make some similar products but are all windows based and most of them have a quite cheap look).
Thanks a lot for the help!

I rooted with motochopper, so now I have root access. I installed and used fstrim, seems like there was a small performance improvement. Not sure if I have anything else I can do to speed it up with root but no custom rom.
Hi i used the unlock tool last night, and it was a pain, as it wouldn't accept my google password! I found a solution on here, after reading what seemed like have the board posts for the TF201. So basically what I did was -
1. Go to the tablet settings, and set a pin code as the unlock method.
2. In Google, set the less secure apps permission.
3. Load the unlock app again, and accept the warnings.
4. When it asks for verification, use the unlock code option.
5. Wait for it to do its thing, and Tablet will reboot.
6. Once finished, restart the Tablet, in top left hand corner during boot it will say this device is unlocked.
Hopefully this will help.
Regards Bill
Thanks Bill,
I tried again today, following your steps, but this didn't worked. My problem is that the unlocker just fails, it never prompted me for the google account password. It saves a file with the unlock date.
I think I need to try again with the factory reset (that I tried in the past actually, and didn't worked).

Just tried this tonight and it worked. No Google account activation but I did set a screen lock. I setup the wifi in the beginning setup screens. and Used the Unlocker from the Asus Tf201 Download
Installed unlocker and opened the program and asked for asus tf201 pin code. System accepted settings and rebooted.
