Help ! Since I've used the script, my gsm Galaxy Nexus doesn't find any network anymore. I've already tried to flash the stock rom (the maguro one, bootloader, radio, system, recovery, wipe date...) without any effect. Don't know what to do else now. Even with a total stock reset the problem is still present. It seems like the phone alternates between airplane mode off and on, without any control on it on the settings. When it try to search the networks it fails. Even emergency calls are impossible ! It tells me "out of service area". Any idea for a solution for that =/ ?

Sorry for my english ^^

@ptisam
Since you used the script as-is, it should have backed up the original nv_data.bin and .md5 in /mnt/sdcard/nv_data_mod/factory.

You can always restore them from there to /data/radio and /factory.

Should you do that, you would have to find another unlocking solution though :).

Oh, I've already wiped the data =( but I finally found another solution. The file /factory/nv.log was renamed as .bak and it seemed to be the issue. Since I've renamed it, everything works fine...

Yeah indeed for the unlock, I don't really understand why it didn't work... It seems to work with other people with gsm galaxy nexus =/ anyway, I'll wait until i receive the unlock code from my carrier, it just a question of a few days

Thanks very much !

those are the files from the original script which were backed up in /mnt/sdcard/nv_data_mod/factory.
the changed files can be found in /mnt/sdcard/nv_data_mod/unlock.

backup your current files as well:
/data/radio/nv_data.bin.md5
/data/radio/nv_data.bin

good luck ;-)

So you confirm your script is working for you without the data drop on a GSM GN?

If so, I'll give it a try. ^^

No it was just the original file from my locked (A1 sim lock) galaxy nexus phone.
I am not even sure if it will work for him.

I have the GSM/HSDPA drops as well, but I can use the phone only with the hack ;-/

Applied the patch, for now it seems stable.

But then again, I have ****ty reception at home with my new carrier, so tomorrow will be the real test to see if I notice any drop.

just to let you all know.

i obtained a unlock code and deactivated the sim lock and i still had the network drops regarding gsm and hsdpa.

so i flashed a new modem: XXKL1 from here http://xdaforums.com/showthread.php?t=1444288

this seems to be stable so i am not sure if the instability is really caused by the hack.

I am in US, got Ireland vodafone locked GN last week.
did all the expected things -unlock boot loader, root, ClockworkRecovery, flashed several new images for radio, OS , etc..
no go - the dreaded screen is still up - curiously though - after paying several "unlock" providers - none of them even came through with the code, all had to refund.

Looks like the solutions at least is understood in this thread - will eagerly await for something that is confirmed functional.

-- or if will get desperate - will try the script - I don't like to get to windows for that.

Thanks in advance ya all!

@sitajony - I didn't had cp command in my "nexus" shell, but managed with RootExplorer and rest of the code, thanks.

The cp not found error can be solved by installing busybox.
That did it for me!

Thanks...the fix worked fine on my (previously) locked vodafone nexus galaxy.
yeey :)

    Unlock your Galaxy Nexus whenever your want :)

    Hello, I've bought my Galaxy Nexus on december, 2 weeks later I've finaly found how unlock my phone :) I live in france and here we've to buy code and it's very expensive...
    "I've made" a Batch script running only on Windows OS but we can see that is a Shell code... (In fact this come from a website in japanese without help and no choice so I've created this batch script)
    After downloading, edit it and press CTRL+H then type in first field this:
    "C:\Program Files (x86)\Android\android-sdk\platform-tools\adb.exe" and type the ADB path on your PC on the second field. (Keep this if it's the same path)
    PRESS CTRL+S and run it...
    The first question is:
    Restore? (Answers: oui=yes, non=no)
    Type "yes" only if you've already tried to unlock and it didn't work...
    Finaly wait few minutes and in the last question, you'll can directly reboot your phone without touching your phone :D

    Please tell me if there're problems or if you want ask me some questions...
    Good luck!

    Since there havent been much more discussion going on and ive recently gotten a simlocked nexus myself, I decided to try out this "hack" and I got the same issue as most with network calls dropping and data dropping and swapping over to roaming and just going nuts.

    I decided to try out another modem so I flashed XXKL1 from http://xdaforums.com/showthread.php?t=1444288 and it has just been working flawlessy for two days now and I also pushed it alot with having webradio streaming nonstop and surfing the web, making calls etc and it didnt drop once and the following day when I was out working passing by different cellstations etc I had the same experience as home.. NO DROPS, so this modem will also help users running old vanilla firmware etc. I think the kernel can screw it up a bit aswell since I saw some posts about ppl still having issues about it (with XXKL1) but that was with custom kernels instead of the one supplied from each rom.

    I havent tried many roms as I went through quite some posts before I decided on one and I chosed Pauls 4.04 (from modaco http://android.modaco.com/topic/351...a-gsm-modaco-custom-rom-for-the-galaxy-nexus/) since it didnt had too much overclock and modified kernel bull**** which otherwise makes your phone unstable and messy and just creates other problems which takes time to find out where it comes from.


    So for me I used the Galaxy Nexus toolkit to unlock and root phone, then I used the patch from this thread and after that I flashed Pauls Ir11 Beta 2 4.04 rom + XXKL1 baseband modem which has been working flawlessy. Always remember to clear data/system/cache and dalvik cache if you are coming from another rom/kernel to avoid strange issues and stay away from wierd kernels unless you wanna risk it ofc then go ahead and have a messy phone :)

    I purchased an unlocked GSM phone and used WugFresh's toolkit to unlock it and reflash with yakju. Before doing this the phone worked fine with my SIM card. Afterthe process I got "SIM network unlock PIN"

    I am seeing a lot of stuff in this thread and after this failure I don't want to do more to my phone than is needed to get it to work.

    What do I need to do at this point to get my phone to use the SIM and have a stock Google Image.

    You help is appreciated.

    Just type your purchased unlock code that you already bought.
