From Cyanogen 2.2.1 to stock 2.1 -LG540

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

[Q] Super reset?

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

RUU & OTA update problem

Hi I have been looking for a solution for the OTA "4.2.2" update, but i haven't find any.. I tried to flash stock recovery but when the update starts it gets stuck and stops there, so that didn't work. I have a completly stock nandroid backup but i'm afraid i will get the problem restoring because my phone has a new partition of flashing ARHD 12 4.2.2
I have read about RUU the ONE but i am afraid it will remove everything including my nandorid backups.. And mess up my partition.
Now, how do i get my phone to update the new OTA eith 4.2.2 Stock ?
Sorry if my english is bad...
Regards

Copy all your sd into the pc, use a ruu and swith to 4.2.2
Or, when you will apply your ota, you had the stock recovery with the relocked bootloader?

Problem coming back to Stock

Dear Community, first of all i want to apologize for my englisch, im from germany.
I have a problem with my HTC cuz im not able to use it anymore. First of all i maybe try to tell u what i have done so far maybe u will find a solution or problem.
First of all i unlocked my bootloader with htc.dev , installed cwm and Android Revolution HD 31.6. After that i gained s-off with the firewater method . All of it was successful.
Like u guess i didnt make an Backup
When i used Arhd i noticed that i didnt seem to stable and i changed the version to 71.1 also for Sense 6.0 . I installed it with cwm and aroma installer i guess and he said that everything was fine and done .
My problem starts at this point cuz when he rebooted the device he stopped at the htc logo and that is the end of the story. Until now nothing else happened , i also retried the installation but with the same result.
After that i read i could go back to a working device when i flash it with stock recovery and rom , I also found a method that worked on several devices in germany .
The author proposed to use a 2.24.161.1 firmware to update the phone and then to flash a stock recovery from the same swisscom device , I followed the instructions but at one point he tells me i should use adb push to move the stock recovery (about 1 GB ) to the backup folder of CWM and then restore the backup the restore my phone.
When i do adb push it says that has been successful but im not able to recover the recovery or to choose the file from sd card when i move it to /sdcard cuz : file not found.
Im really scared that my device is bricked even when it worked before with arhd 31.6 and only the flash to 71.1 make the problems.
i would be really thankful when some of u pro or even of with the solution could help me .

ARHD 71.1 requires TWRP 2.6.3.3 recovery or newer. You can get the latest version TWRP 2.7.1.2 here. Flash this bootloader and then re-install 71.1.

HELP with EFS backup. Imei 0 and Baseband Not Found :(

First of all, I am an Argentine using the google translator.
Hello, good evening, I urgently need help to solve the following problem:
I have a moto g5s plus, xt18000, with android 8, to which I apply a custom rom HAVOC-OS-v3.5 TEN [10.0] - [SANDERS]). As God commands, backup the EFS folder with TWRP and apply the ROM.
The rom worked wonderfully, but it had no mobile network. Yes IMEI.
Perform the restore from TWRP, but it remained the same, without network, but with IMEI.
I went back to a stock 8 to see if I got the signal back. In addition to not recovering it, I LOST THE IMEI and BASEBAND.
Install a stock 7 and nothing. In all (in 8 and 7) install twrp and restore, but without it working.
And just in case I googled EVERYTHING, in ALL languages.
It gives me a lot of anger because I have the blessed backup of the EFS folder and it does not work for ANYTHING.
I know there are many posts on this topic but in none I found a solution, or guide.
Can somebody help me?
Thank you.
EDIT: In fastboot I Have my ORIGINAL IMEI. But in android is 0.

Hi maurorisuenio, i had the same issue flashing evo x rom on my wife phone. I spent almost 1 day to solve the problem, i'll try to give you my step to step guide, it worked for me.
- from custom rom flash back to stock rom, i used RETEU version 8.1 (i don't know what's the south america stock rom), on xda is full of thread "how to flash stock rom"
- flash custom recovery 'cause when you flash stock rom it repleace custom recovery with original one.
- now restore your EFS backup
- boot the phone, you should get back your IMEI but still no network signal
- flash the custom rom you want wiping system/data/cache just to have a clean install
-reboot your phone.
As i said it worked for me, hope it's ok for you as well.

Download the latest stock firmware and flash it in fastboot mode and remove sim before flashing and after phone boots insert sim, you will get your signal and imei back
