Hi everybody.
I have an optimus black with Nova V5 and it work very fine, and I´m root.
Well I want unlock my mobile by imei , I have unlock code, but the problem is, the instruction to unlock says "you can´t be root"
I have Nova v5 , can I flash from sd with Nova 3 (I think Nova3 use v10b, but i ´m not sure) and use gingerbreak 1.2 ?
When I am not root , Can I use the recovery?
I need unroot mobile what is the best solution for it?
Thanks and Regards
Emergency recovery your stock firmware with LG Mobile Support tool, factory reset, and then unlock with your code.
Then you can flash whatever Rom (custom or stock) you want.
PS. Before anything, in order to keep your data, you can do a cwm backup, Emergency recovery your stock firmware with LG Mobile Support tool, do a Factory reset, flash V10A with KDZ updater, do a Factory reset, unlock with your code, root with Gingerbreak, install CWM and restore your backup with CWM. Voila! You'r done!
It may work even if you flash a stock firmware with KDZ updater, but you have to pay attention that Nova uses ext4 filesystem and stock uses ext3, and mixing those leads to trouble!

It looks like that simple flash via official LG tool from Windows cannot revert to stock Android 2.1 from 2.2.1. LG540 stuck after first animation.
I guest that is (was) because recovery image was written somewhere in rom, and only few roms can be used in that combination ( fastboot euro 2.1)
Can somebody tell to me: how to remove recovery.img , reset LG to orginal state so Windows flash can flash stock Android 2.1. ( gold card) ?
Thanks for any reply.
if you still have clockwork installed then you can just reflash the backup of 2.1 that we were all told to make before we installed 2.2.1
Yes, that is one solution, but I DONT WONT fastboot, or clockwork moded firmwares. I wont original LG software.
And I wont original flash procedure from LG ( from windows)
first: recover your 2.1 (with fastboot, recovery and etc. )
second: then flash phone with original lg ROM
Not working I tried that combination several times
i'll upload my recovery from 2.1 and try that. (about in 10 minutes)
Ps. have you tryed to flash with kdz updater too ?
Waiting for your recovery
Yes, the whole point is that after you put Clockwork moded 2.1 there is no chance to make flash with KDZ uploader ( and that is what I need)
I dont know what that clockrecovery mode write to memory of LG , but it is obivious that KDZ cannot erase that. And for that reason after successful flash from KDZ uploader LG540 is stuck after animation. But as soon I re-flashed LG with clockwork recovery it starts to work again. So reason must be in that rom.
hmm. it takes more than 10 minute :S shows about...hour (220mb)
220MB?
Hm, normal roms have size about 140 MB, you have monster
i know that. i have several apps installed on it. when you dont want them. then wipe from clockworkmod to factory reset.
but. i've just tryed to recover my backup from 2.2.1 (cm6.1.1) to this 2.1 and it booted up as normal.

You say you try to recover your backup from 2.2.1 to 2.1. How you do that?
Via KDZ tool?
no, via clockworkmod ...
i was saying , that the recover from 2.2.1 to 2.1 worked with this backup
read my third post
.. but I DONT WONT fastboot, or clockwork moded firmwares. I wont original LG software.

yes, i agree that. flash this recovery then try to flash original 20B with kdz updater
i'm updateing right now my phone to original 2.1 with lg mobile support tool
Your backup has sd part and I dont have sd partition on card: so does it will work?
how i've just downgraded from 2.2.1 to 2.1:
1) recovered my backup from 2.1 (yes i know that it's a big recovery, because i have several apps installed on it, but it doesn't matter, you can do wipe/factory reset if you want)
http://www.multiupload.com/86OZ7RA1W5
2)now connected my phone to pc and installed lg mobile support tool(this gived me drivers too ) (from lg site)
3)now i've "upgraded" my phone via "lg mobile support tool"
4) and now, i'm on official 2.1 rom
yeah. that's ok when appears error with sd-ext
Just now I use same technuiqe: hope will work.
It looks like that KDZ updater is less powerfull then suport tool, but I have still to wait and see if Updater tool will finish flashing
DIDNOT WORK
hmm. that's interesting. for me worked.
Now I will try to use your backup: so need to instal fastboot and clockwork recovery rom: then I will wipe all, use yours backup: and then follow your instruction.
Does you flash Blackquatrx ROM ( or something like that)?
It look like that one of those installation erase original boot image, and that will be whole problem, to revert original boot.img from untouched LG540 2.1
Hi there,
Not long ago i got a P970 and proceeded to root it and install CWM on my device using an all in one solution from this site, unfortunately it didn't seem to create a backup of the stock bootloader and i am unable to perform updates to the device as they all try to boot in to the stock bootloader to finish the update process which is ofc missing, does anyone have a copy of the stock bootloader for the P970, incase its of relevance i'm using one in the UK on the Orange network
I thank you in advance for any replies
Bump anyone got a copy of the bootloader?
If you flash stock vanilla rom it will overwrite CWM with stock.

Couple of small issues is that i dont want to lose everything i've installed and setup so far and the only images i can find of the stock ROM's are .kdz files which use the LG tools to flash and those require me to be able to boot to the standard software update tool found on the phone which doesn't seem to work with CWM installed as i can't do any OTA updates either.
dude, I already answered to you by pm. this cannot be saved, you have to flash again to recover the standard loader. AND, you don't have to boot or something else except going in s/w mode. just backup your apps / datas with 3nd party app then restore them after the flash. standard recovery is absolutely uneeded and is even useless. you might restore full datas with cwm by going into the advanced menu.
How To downgrade LG BLACK 2.3.4 to 2.2
What exactly is your rom now? Is is custom, or stock?
Factory reset either via settings, or cwm is the first step, then either restore a backup of froyo, you have got, or flash a v10x version via smartflash (also perform a factory reset before)
Sent from my LG-P970 using Tapatalk
why downgrade?
this method is simple and works great..
http://forum.xda-developers.com/showthread.php?t=1448803
after this you will have v10 (froyo).. you can also do a factory upgrade after this step to get original lg upgrade to GB.
Hello everybody! I flashed on my LGP880 the rom eternity(cm10.1) and now i want to come back to stock rom. for me was v10f. but i don't know how because i haven't any PC now and i can't flash the file .kdz
Today i tried to make reset from original recovery but nothing changed and at reboot was again CMboot(eternity rom).
So, i want to ask: there is a way to make fullreset for come back in stock rom ( v10f without root and recovery)?

The only way is to flash .kdz
Or you may go back with cwm backup which was taken before cm install. Don't know wether it work.

If you had taken the stock backup before installing custom rom, you can install the recovery apk form this page http://forum.xda-developers.com/showthread.php?t=2123602&page=10 , install it as normal apk, reboot into recovery and restore with your backup.
It worked for me perfectly

There s a way to make Super Reset on 4X HD, but after a super reset guss what comes...
An ULTRA Reset which is basically vol- and Powering 0n the device.
After an ULTRA Reset if you are not satisfied with the results, you can try making an ULTIMATE RESET, by downloading v10h firmware and flashing it with tool called KDZ.
You can find many tutorials about this on the General section on this forum.
You previous system doesnt exist anymore.
Only way to get back to any stock LG Rom is sadly the pc-kdz way

I'm experiencing some problems and would like to go back to the stock rom. Currently on 10.1 Nightlies
Would I have to use this tool? http://forum.xda-developers.com/showthread.php?t=2069723
I can keep the custom recovery right?
I have no idea how to do this though. All I have is the original EUR 20A kdz file.
Thanks.
No CWM backup?

No CWM backup before CM install? You can just restore or otherwise you have to use that tool. You can install CWM again after kdz flash. It wouldn't be a problem.
Remember you have to remove and reinsert battery or otherwise you may not be able to get into S/W mode and you also get BSOD on pc.
I also had probs on CM 10.1 RC2.
Just wipe it, then start from scratch.
Hi,
I would just reflash by doing a full wipe, restore a full backup of lg stock, then doing a factory reset and wipe to have a clean rom. But be careful not to wipe any backups you have its always best to keep them on external storage.
There is always the option of using the LG tool to factory reset the phone (enter sw upgrade mode then plug it into the computer.. follow the instructions in one of the mean threads on the subject.. liek http://forum.xda-developers.com/showthread.php?t=2069723). The only real problem is data loss. Use a app to backup sms first. i like to use this one - and backup to external storage.

I would just use the LG tool to reset the phone, after doing a wipe.
Cant wait for the next android verson that could come with cloud backups

If you want to go back to stock OS with a clean install, the best is LGFlash Tool.
Remember that will wipe everything in the internal memory.
Next time (if you like to try other OS and change between them often) backup your
OS with CWM.
