[Root] Help, can't root v20c

Posting on behalf of a friend. Here goes:
0) Yes, we've read http://forum.xda-developers.com/showthread.php?t=1487105
1) Stuck on V20C. The official LG update utility says this is the most up-to-date version.
2) Have tried http://forum.xda-developers.com/showthread.php?t=1442588
3) Have tried http://forum.xda-developers.com/showthread.php?t=1480392
4) Have tried method on Cyanogenmod wiki.
Nothing worked. Is there a method that's confirmed to work for V20C out there, or have we just screwed up something? Attempting to eventually install Cyanogenmod.

indeed you can't downgrade using LG updater.. no problem, friend, here's your solution..
http://forum.xda-developers.com/showthread.php?t=1448803
1. download the v10a firmware
2. install the firmware using SmartFlash Tool
3. root the v10a using blackjack
4. install ROM manager, and from there, install CWM
5. you can use the CWM recovery to install another custom ROM

Go here http://forum.xda-developers.com/showthread.php?t=1566532 by the end of it you'll have your version ready to flash and root at your will

Ah, thank you very much.
We weren't aware that the methods for V20C and other V20 firmwares were interchangeable - after several failed attempts and several more perusals through XDA we were beginning to suspect that V20C was unrootable as nobody seemed to mention this version.
Glad we were wrong, now happily running CM7. Phone is reportedly much faster and responsive now. Thanks for the help!

[Q] SU660 ICS Brick?

Hi all,
i just tried to install the ics rom v30c on my p990 (su660), no problems on the installing with smartflash,
but when i want to turn my phone it gets stuck on the lg bootlogo, so i thought this rom is only for the su660, why does this not work??
so i checked my phone again, under the battery is written: made in korea... so this is a su660 right?
so people can someone tell me wheres the fault?? ^^

Wow you were trying to install SU660 ROM on P990? Nice idea m8, I'm convinced if you try it again (maybe take the latest .kdz from today) it will work! Don't forget to perform a full wipe and format your SD cards before. At your own risk of course, but hey maybe you are the guy who can finally tell us if the su660 ROM works on our p990s ! :good:
But seriously, if you don't even know if you own a P990 or a SU660 you shoudln't be flashing around and instead inform yourself a bit better before you start doing this.
If your bottom buttons look like this you have a SU660 (which I believe you don't have)

It's only the SU660 if it has two capacitive buttons and one physical button at the bottom.
The p990 has 4 capacitive buttons below.

Sigh, another bambi (no offense) on XDA developers who found out one of the only ways to potentially fully brick his phone. Have you tried nvflash and smartflash? You could have averted this by googling su660 but....

re-lock bootloader

Hello Guys,
I am not a dev and am looking for some info.
I recently unlocked bootloader, rooted using RAZRI Root2 and installed a few custom roms however, neither of the roms work really smoothly and my mobile is now slow.
1. How can i re-lock the bootloader and install the official firmware?
2. My mobile was locked to Orange, can I install the Retail GB if so how?
Please remember I am not a dev so step by step instructions would be greatly appreciated:good:

I already created an bat for doing that. I'll post it here as soon as I'm back home.

Wonderful - I am back to stock ROM. I have en EU but live in the UK, is this an issue and can I now receive OTA update without bricking my mobile?

Relock your Bootloader
You'll need an complete JB (4.1.2) Fastboot File of your Region for doing that!
Copy the content of the View attachment 2175015 into the extracted Fastboot File Folder

Enable USB Debugging on your RAZR i and connect it with your PC (Driver should be installed already )
Start the Re-lock Bootloader.bat
! Your Data & internal SD will get wiped !
Enjoy your relocked Bootloader
The Message on Boot, that your Bootloader was unlocked will still showing up !​

You won't brick by updating OTA. But from what I've read over here in Germany, an User already asked Moto twice, if an Update for the Razr i to 4.2.2 or 4.3 will come. Moto stated, there're no more Updates planned (That's Moto). So don't worry about that

Can't unlock bootloader

I'm trying to unlock the bootloader of my C6603 and I keep getting errors or bootloops. My bootloader can be unlocked according to the attached screen.
I tried with Minimal ADB and I'm getting bootloops and with Sony Bootloader Unlock it's failing, according to this pic:

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Drivers are installed correctly.
What's the catch?

Try using the fastboot package provided by DooMLoRD in his thread - http://forum.xda-developers.com/showthread.php?t=2153261
Also, the unlock key they send you is case sensitive, so double check what you're entering.

I tried with DL's method and just tried with FT. STILL getting BOOTLOOPS !

Try flashing a stock FTF with full wipe, then try again.
Also, I just noticed that your IMEI number is in your screenshot. I would remove it from the image if I were you.

Tried it. Still getting bootloops.

Then I can't think of anything else apart from trying a different USB cable/port or PC, but that probably won't make any difference.
When I unlocked my bootloader it worked straight away with no problems.

It worked on my XS. Looks like this one is a mystery.
Edit: CLEAN flashed it and tried an other port. Worked. Thanks for the suggestion!

You're welcome.

As I remember, flashing an unlocked-BL phone won't relock it, right? I'd like to relock it after gaining root on the .569.

That's correct.

Don't forget to backup your TA before you unlock the bootloader. Otherwise you'll loose your DRM keys forever and won't be able to re lock your bootloader

MJ5 or MI9 when downgrading?!?

For some reason my version says mi9 instead of mj5. I completed all steps except step 10 as I wanted to at least get back to nb4. Any idea on what may have happened???

I have used those steps twice to get my phone back to MJ5. They work. There is either something your missing or you have upgraded to something different and are having issues going back.
but it does work.

Even the MI9 file included in the list?

Yes all files less the Mega one which is just a mirror to the MI9 fix anyway.

Got it. Didn't repartition. Thanks

I was asked "forced" to update last night and lost my root. I was wondering if there was any way to get back to MI9?? THANKS
Where is this thread?? And is it up to date??

Once you're on a new build its impossible to downgrade because the bootloader is locked. So sorry to say you're stuck. The builds ending with MJ5, and NB4 are android 4.3 jellybean and aren't bad at all! The 4.4 NC2, and MLG have quirks.
The restore to MJ5 thread is here http://forum.xda-developers.com/showthread.php?t=2559715
MI9 is Odin flashable and available here http://www.mediafire.com/?jmypf8ggtxu1a61
It's only good if you're still on MI9.
There is no restore method for any 4.4 versions. Just some modified NC2 or MLG roms available.
