Hello,
I have received this old S2-i9100P from a friend as a temporary replacement, and it is simlocked with SFR, which is a French provider. I have tried to desimlock it with an app, the app said "done", but really nothing was done. To the contrary, now I can't even enter the pin code of my sim card(Belgian provider), as it is always saying "sim pin operation failed". I still have access to my IMEi, which starts with "35848...". I have read here and there that when this happens, you have to replace some files in the efs folder, namely "nv_data.bin" and "nv_data.bin.md5" with ".nv_data.bak" and ".nv_data.bak.md5". Is it the right way to do it ? Is that all I have to do ? Do I need to backup anything else, like for example everything that is present in the root ?
Also, in the mean time, I have installed LineageOS 14.1, which works well, is it ok or should I flash the phone with a stock rom ?
Thanks !

Hi....
I made a mistake of trying out lokiwiz's tool to try & unlock the SIMLock on my Cingular 3100.
Now, whenever I insert a SIM card, I get a "Data crashes." error message. It stays on as long as the phone function is turned on so that I cannot use the phone for anything else.
I have the necessary files that the lokiwiz tool backed up to restore.
I've tried to restore the lock_backup.bin file (obtained with the lokiwiz0.3a program to obtain the SIM lock code) with lokiwiz0.2b but the error message still returns.
Does anyone know what is the problem? Is the phone useless now?
It seems the radio function that is activated by the presence of the SIM card is in an error state.
Anyone with experience with this, please point me in the right direction.
The warranty is out so sending the phone back to Cingular is out of the question & too costly.
Thanks in advance!
Problem fixed!
Problem fixed using the supercid.bin file obtained during the SuperCID unlocking.
Now, to figure out how to SIM Unlock.
I did the same.
Hi Konker, I did the same as you trying the lokiwiz, I had the data crashes problem and then reflashed the supercid bin file back and this helped, now I am able to use any sim card in the phone but no signal (service) at all , after all this I was able to obtain the unlocking code from cingular but now I don't know where to enter it, as the phone receives any sim card and gives total access without showing the screen to enter the unlocking code, do you know how to reestablish the phone to it's original state where the unlock code is requested each time you enter a different sim??
Hello everyone. I have one Hero100. I have the code for unlock but the phone has failed to unlock. It's locked on orange. When I enter the code , I get no service on the screen. and when I restart it, it asks for the unlock code again. How can I go about this? Its a bit strange.
sounds like orange gave you an incorrect code...
you have put a NON-orange sim in when you try this, yes?
if it fails again, go back to orange and ask for the correct code, as they have the wrong one.
The code is working. When I put the Code I get a successful msg but it wont pick up the network and also when it restarts it asks folr the code again.
The same
I have got the same problem.
I have got that unlock number but after unlocking phone, there is no range at all and info 'no service', but i am able to use 'Sim Toolkit'.
Where is a problem???
hi i'm having the same problem code is gud and it works but after that it says no servic. and when i restart or put any other sim again and turn on the phone it again asks for the code . whats wrong plz
I think not so many people have seen this phone.
I am also having this issue. Simlocked to Orange got my code and put it in and it was successful then it just stays on the 'unlocking sim' screen.
Been using HTC with windows mobile for years but decided to try android. Am I doign something wrong as I cant seem to access any phone fucntionality without putting a sim in then I get this problem we are having.
On a WM device you would still be able to access everything without having a sim in- just using it n PDA mode
, I am having the exact same problem. I have a HTC hero from orange as my contract phone. I have bought the unlock code from from swift unlock (ebay) and entered the code when prompted. The phone says the network is unlocked but the I can't get any network service, and if toggled the flight mode on and off or switched the phone off and on it will ask for the code again. If I put the orange sim in everything is back to normal. I even tried to hard reset the phone and have a fresh start while the unsupported sim is inserted but the same happens again with the addition of a message "unlocking sim". I thought the code was wrong or something, so I got the code again this time from a high street shop and it was the same code. So nothing is wrong with code itself. The guy at the shop told me that he has great problems with unlocking this phone as some seem to accept the code without any problems and others have this no service issue and he doesn't know the reason for it. I am thinking of flashing a new firmware and radio and see what happens, but this will be probably tomorrow. Sorry for my long post, but I wanted you to know that there is nothing wrong with code itself.
Yeah I dont think there is a problem with my code either. Im new to android but have been a winmo user for years, I havent rooted my Hero yet (only got it today) but that was going to be what I try next: root then network unlock.
Let us know what happens when you flash yours.
Possible Solution
When i unlocked my phone i thought the exact same thing, that it hadn't worked - it said no network, something something about my sim, etc. Later on though, I went outside and it was working. Unbelieveable i thought. Turns out when your in an area with no reception (my house) the Hero decides to boldly make sure you know that it's not getting any signal by giving you big scary messages
So once you've entered the unlock code, let it load up the UI fully, turn phone off, and then turn on again and put it somewhere you definately get a recpetion
Anyway this might answer your problems, then again might not.
Thanks for the suggestion but I dont think that is the problem in my case as I do get reception. Although for me once I have put the unlock could it it says success (or whatever) then goes to saying 'unlocking sim' it doesn't atually load up any interface.
Out of intereset where did you (all) your get your unlock code? I got mine from Unlock Now, anyone else got a code from them and can confirm it works?
Hi, I have flashed the new modaco 2.2 rom, and inserted the unsupported sim, but sadly with the same exact result "no service". I then flashed the latest radio from modaco, and repeated the steps but this time after the first time you put your unlock code it will say "no service as usual" but if you try to toggle flight mode on and off the phone will prompt for the code again and then it will greet you with a no sim is inserted or so, so it seems with the new radio the phone doesn't even detect your sim. If I put the orange sim everything is back to normal again even with the new radio.
I wanted to sell my Galaxy s2, the guy wanted it to be factory reset, with the original firmware.
I have downloaded GT-I9100_XME_I9100XWKF1 firmware, it worked. But I had the "sim locked" symbol in the notification bar, so I wanted to unlock it.
I downloaded CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4, and rooted the phone.
Downloaded the Galaxy Unlock app from market place, followed steps 1-3. Phone rebooted.
The unlock didn't work, Instead of a sim locked symbol in the notification bar, I got this stop symbol (like in "no smoking" sign). When I try to go to settings->wireless and mobile network->mobile network, I get "Insert Sim Card to access network services" (sim card is insert correctly, i double checked). When I try to make a call, same message "Mobile Network not Avaliable".
I did some search on the forum, one of the guys said that I should check if the IMEI is matching, I dialed *#06# and got the word: "IMEI", no serial, just that.
I tried to go to Unlock Galaxy app and do a restore efs (step 4), i get the message "You don't have efs save in /sdcard/Galaxy_S_Unlock"
I tried the sim card in a different phone, it works. Tried a different sim in galaxy, it doesn't work.
I tried to do a reset of the device from a backup I had from a month ago, it didn't help, same problem.
What can I do?

Thank you for the reply, I have tried the GSII_Repair, just now, I installed busybox on android device, and followed the steps.
Step 1 was succesful, so was 2.
After trying step 3 i got the message : "You dont have .nv_data.bak and his md5 files, canceled"
I did more research and found out that I have network lock. Punching the code *#7465625# confirmed it.
I tried that tutorial: http://forum.xda-developers.com/showthread.php?t=1369474
to fix it, it didnt work because I didn't have the hex adress 181468 nor 18145C in my nv_data.bin
do not use galaxy s2 unlock, try galaxy S unlock, this one is better but with greater risk but never heard anyone had issue with this. Use this then do the GS repair again.
should this one did not work, i suggest you do odin flash of official roms. Tried flashing the rom 3 times, I was able to fix the same problem with my galaxy tab before doing that. goodluck.
THank you ! *FIXED*
I just used the original Samsung Unlock, and I didn't notice that it had a fix built in. Tried it and it worked !

I have a HDC Galaxy S4 Legend and for now the problem is that it says "SIM is not detected" also I see that IMEI is null.
How I got to this situation? I' really a newbie in all this things, I just wanted to install a new ROM and after reading and searching and trying to install some kind of recovery files I got a recovery menu in Chinese. Because I didn't know what option to choose I selected something after that the phone started to vibrating and doing some noisy signal I just took off the battery cause it didn't stop. So, of course it did something bad, but after
more straggling I found a recovery file that showed me an English menu then I installed the new ROM hopping it will solve my problem. But, it is not. My phone is working fine (really surprising for me), but thew IMEI is null and SIM is not detected.
What can I do?
I tried to write IMEI inside MTK Tools (GPRS option) but it says "Fail to write IMEI due to radio unavailable or something else"
Also I tried to enter CDS Information --> Radio Information and type AT+EGMR=1,7,"MY IMEI" and I got "AT command is failed to send"
Before "doing all phone tricks" I did a backup from recovery menu, I got this file but I don't know if it can help me to restore IMEI.
Please someone help me, I'm so lost and disappointed.
Waited for a phone so long and now cannot use it.
Hello, and thanks for helping me: I've used a Z7 Max since many month on 3.08 flashed on my phone without any problems. but after having flashed a new rom today (yirom's CM12), the phone cannot detect any sim, in no one slot.
I've tried to go back to 3.08, with nubia tool updater and with twrp recovery, but even after full wipes, impossible to detect sim cards. If I Check Msim settings, it says "deactivate", not "no card".
The phone never answer sim lock pin .
Is there a way to get out of there? Thank you very much and sorry for my english.
Flash another ROM (Z7max（NX505J）电信4G双卡 V3.22)
It is not a rom problem. I have lost IMEI, but have the .nv file. But when i try to nrestore them with qbst, the phone answer the pin code again and again and again....
Use google search
Stupid. For those who have this problem, i solved it by trying again 'd again with qbst (and force efs verification). Nota: my computer did 3 *.nv backup of imei, only one was correct, the bigger one.
