This method has been discovered by some people in htcmania with network problems.

To fix network problems they do this process with orcusen's help, and someone realized that his phone was unlocked.

After that, the method was used by many people to unlock the phone succesfully.

AW: Tutorial - SIM Unlock

Well you definitly should backup the nvram partition, before you try to touch anything related to it. I'd say, until you provide a way of how to back it up, you should delete the information above, since it can seriously screw up phones... look for a post made by xonar_ he explained somewhere, how to back up nvram partition. As soon as this info is in there, I think this thread is a good one. But until then, it seems to dangerous to me...

See i am always in favour of sharing information and knowledge, but as long as things arent bullet proof, they always risk to brick noobs' phones. That's the only thing i am concerned about... I am quite sure, that otherwise lots of new threads about: tried to unlock my phone, now my phone doesnt work anymore will pop up ;)
[LG Optimus Black] jes0411:
I don't know about that, only say what I see in other forum, but I don't know about nvram partition nor what erase cp really does.

I think if this process afects nvram partition, it'll be good if there is an easy way to backup it and restore if something goes grong.

For now nobody reported problems, only people that did something grong in tutty and can't restore imei, but finally they could do it.

AW: Tutorial - SIM Unlock

Yes it seems to work, though you should backup your nvram before doing anything to it. If you guys dont wanna listen to me... well your problem... i just dont wanna have to deal with noobs every day, who have problems with or after the procedure. I am only making suggestions. Over an out.
[LG Optimus Black] re4lsk:
Dont be so uptight, everything here on XDA is not bulletproof, if somene is trying to do something that does not understand is not the fault of the OP, people that come to XDA should be aware that here is not the place to take things lightly.

We all started as noobs, but reading, searching and understanding makes us take a step away from noobishness (I think that word doesnt even exist) some faster than others, even I had a bricked my phone the first time I tried to flash CM7(even when I'd read the instructions carefully), but that didnt stopped Me trying to fix my own mess, I read, searched and read again until I could fix My phone, all that without having posted a Q in the CM7 thread or opening a Q in general subforum, the moral of the story is if you broke it you fix it with your own tools(brain).

PS I'm still a noob, one that can compile a kernel and a rom but a noob nonetheless.

AW: Tutorial - SIM Unlock

Search for: xonar_ backup nvram

You have to dd it to a .img file first, then copy it from your sdcard to your phone, just to be on the safe side.
[LG Optimus Black] Sobralobo:
Is there a way to know if the nvram is corrupted ? I used that method last year because of my phone being always in emergency mode after receiving too many sms (more than 500 in a short time were sent)

Alternative for IMEI recover http://xdaforums.com/showthread.php?p=32916410#post32916410
[LG Optimus Black] N00BY0815:
Just to quickly answer your question properly. Here is how I did it. There might be other ways, but this one worked quite well for me:

Connect your phone with usb debugging enabled and make sure it's well connected:

adb devices #You should see some number now.

adb shell

make sure you got superuser rights:

su

a # will appear

dd if=/dev/block/mmcblk0p11 of=/sdcard/nvram.img #or whatever you wanna call the backed up .img file.

then exit the shell

then type:

adb pull /sdcard/nvram.img #or whatever you called the backup img

you ll find it in your adb folder then. Make sure you keep it safe ;)

*Important commands are in RED. Maybe I missed something, so if you have problems, just tell me. But that should be pretty much it.

Of course you need adb set up, for this to work. There is a small package in my Noob-HOW-TO and you can also find A LOT of tutorials all over xda about adb.
[LG Optimus Black] repulse:
Maybe OP should add it in first post ;)

Change dd if= to the path to the .img file and of=nvrampartition. So just swap the command. CMIIW, havent tried it yet...

Wipe Data/factory reset

For the noobs (like me) You've missed a step in the tutorial. You should do a wipe data/ factory reset after the phone reboots or the phone will brick.
[LG Optimus Black] Olynth:
I followed the steps , it works great. The only problem is that now phone is charging slowly even in wall socket.

Changed rom , charger , wall socket but still same thing.

Any ideas?
[LG Optimus Black] N00BY0815:
Did you backup your nvram? If not, try a factory reset from settings.
[LG Optimus Black] Olynth:
I dint backup nvram , i did factory reset from hidden menu every time i installed a rom.
[LG Optimus Black] N00BY0815:
Maybe also check the time it takes to fully charge it. If it is more, than before, it might actually even be a hardware failure. Try to compare it with the time it takes to charge it turned off. I might also see, how long my OB takes for that?
[LG Optimus Black] Olynth:
With the phone on , it charges from 20-30% to 100% in ~3-4 hours , before it was max 1 hour and some minutes.

Will try with phone off. Thanks :)

LE: i was thinking the problem comes from the usb switching from hidden menu but i dont really know what it could be , after unlock , under AP CP USB Switching , Current Status is "[null]" ,

i select AP USB , retain, but after the phone reboots it`s still "[null]" . Is this how it should be ?

LE2: i checked NO RETENTION , the phone rebooted and now it charges normally :D , connected to pc it charges slowly but i can`t use it as storage or anything else , just for charging.

I have a soft bricked S3 thats really stumped me. Its hanging at the verizon boot video so i figured i would just ODIN back to stock and be done with it. Everytime i try to flash VRALEC.bootchain.tar.md5 i fail. I tried to flash stock.vzw_root66 and i fail. I tried to flash COMBINATION_I535VRBLK3_I535VZWBLK3_381038_REV09_user_low_ship.tar.md5 and i fail. Ive tried different cables and different USB ports but i cant get odin to flash anything. Please help lol. I am using a NON rooted device.
[Verizon Samsung Galaxy S III] corbn89:
Are you putting the .tar file in the PDA slot in Odin?

Is your phone in download mode?

What base was you phone when it was working? ICS or JB?

If ICS stick with flashing root66 ICS for now (not any bootchains or modems) so that we can focus of getting your phone working first before any type of upgrade.

Also, if you cannot restore your phone by simply flashing root66 in Odin, follow this guide HOW-TO Unbrick Your Soft-Bricked Galaxy S III
[Verizon Samsung Galaxy S III] heyitsdan03:
I am a base ICS and yes i have the phone in download mode, and i am using the pda slot but i cant get anything at all to flash sucessfully. That is the guide that i got the files from and i cant even get the first file to flash....

1.Open up ODIN

2.Select only the following box: F. Reset Time

3.Flash the VRALEC bootchain in the PDA section and wait for a PASS message

Thats where i get a fail message

Did you check your MD5's? Also, just confirming that you already tried to restore by flashing root66 .tar in PDA with only Auto Reboot and F. Reset checked off? Also, read the second post in that guide and see if your symptoms are similar to the guide's second brick scenario.

Flash this (stock bootchain) in PDA: http://truelinux.net/sch-i535/bootchains/BOOTLOADER_I535VRALF2_618049_REV09_user_low_ship.tar.md5

then download this (stock rom), unzip it, and flash in PDA:

http://goo.im/devs/invisiblek/i535/...535VZWALG1_743127_REV09_user_low_ship.tar.zip

Having so many files fail with an Odin flash makes me think the error is caused by something else, though...
[Verizon Samsung Galaxy S III] heyitsdan03:
What else could it be?
[Verizon Samsung Galaxy S III] letinsh:
Honestly, we've reached the limit of my experience. Must issues with Odin result from the physical connection. I know you tried different cords and different ports. I assume you're doing this, but make sure your usb cable is plugged into a port on the motherboard, not a hub or remote port.

I honestly don't know what the next step is... Reinstall drivers and Odin?
[Verizon Samsung Galaxy S III] heyitsdan03:
I even went as far as to use a different computer all together.. Fails on everything
[Verizon Samsung Galaxy S III] letinsh:
The only other thing I can think is to Odin a pit file first, then the rom, but the problem isn't that Odin is failing at the pit file so I don't know if that would make a difference....

If you do try that, the pits can be found here:

http://d2tehp.chickenkiller.com:22222/pits/

Make sure you grab the sch-I535 one (32 or 16gb,which ever you have)

Follow the directions in this post (just start reading near the bottom where it says "invisiblek ripped his pit...") and use the boot chain I liked you to earlier.

http://xdaforums.com/showpost.php?p=30618458&postcount=57

It almost sounds like you're flashing a Verizon rom to a non Verizon phone (just by the way Odin is failing) but your OP says the phone is freezing at the Verizon splash screen...

Sorry I'm not more help :(
[Verizon Samsung Galaxy S III] SlimSnoopOS:
I've been keeping an eye on this thread to see if anything suggested by corbn89 or letinsh would help. Man, I'm shocked nothing had worked though. Can you try Odin flashing the VRALF2 kernel from Invisiblek's thread?

http://rootzwiki.com/topic/29256-tutorial-rootrecoverybootloader-unlockicsjb-verizon-galaxy-s-iii/

In my head, I'm wondering how much of the OTA actually downloaded. Whether it's 4.1.1 or if you're still ICS cuz the JB kernel may not have been flashed yet.

Edit:

I'm really thinking its the kernel not being flashed or the system based on these two errors he was receiving:

initial OP Kernel error:

<ID:0/005> aboot.mbn

<ID:0/005> NAND Write Start!!

<ID:0/005> FAIL!

in another post following SoftBrick method, System error:

<ID:0/005> NAND Write Start!!

<ID:0/005> recovery.img

<ID:0/005> system.img.ext4

<ID:0/005> FAIL! (WP)

My thing is though, the only boot.tar I can find is the VRALF2 one. I'm not sure if he needs exactly that one or the VRBLK3 tar, which I haven't seen just yet. Anyone know of a VRBLK3 kernel tar?

**Edit #2: I must say, it really sucks with the xda search feature being down right now. I found the OTA VRBLK3 boot.img, it's on open1your1eyes0 Jelly Bean guide under "optional downloads" for the VRBLK3 image downloads. Try Odin flashing that VRBLK3 kernel tar from his thread:

http://xdaforums.com/showthread.php?t=1974114

**I prefer if you Odin flash this first to see if it takes.

Iucidium you've got 622 posts and 70 thanks, that tells me you both know plenty about android to fix this by yourself and that you make a lot of really **** posts. Asking you not to make stupid threads is not being on a "tech high-horse" as you so quaintly put it, it's to deter lazy people like you from posting any old rubbish questions which anyone with two brain cells could easily work out. Clearly it's not working. Clearly you don't know what a forum is either, so I'll help you out - it's a place where ideas are exchanged. It's most certainely not a place where you can come demanding information from people to make up for your simultaneous lack of intelligence and lack of self confidence to follow through on your ideas.

It's very admirable you're trying to help a friend and there is no need to apoligize for it, but I'm sure he (like the rest of XDA users) would be much happier if you'd not use XDA as your personal answer machine, but use - wait for it - your brain for that!
