hello everyone
i'm not pro in things like this so don't use the hard terms or something. A few days back, i updated my phone to cyanogen 2.2.1. A friend helped me. I want to downgrade now. But, he hasn't made a backup and he hasn't one. So we tried a few options to downgrade, but all of them doesn't work. So my question is: Has someone a backup? We tried already a backup, but the 'data was to large'. So if you upload, please, be sure that it works!!
Thanks in advance
There is no way to put your LG to original state. From now you can only install moddified ROMs, but you cannot put original ROMs ( from LG)
First you need to enter in fastboot mode and make command "fastboot -w"
That will wipe all data that current ROM create. Now when LG is without that data put it in Download mode, and with KDZ updatr update to any fastboot ROM you can find on this or similar page. It should work without any problems.
P.S If you dont wont to setup phone any time you change ROM, make one backup with Clockworkrecovery or vit Amon Ra.
So if you do something bad, you just eneter to recovery mode, and put all data back .
when installed a fastboot rom you could flash an original rom?
pashinator- I read your instruction you give "long time ago": but nothing.
I can always install any room, but only roms with fastboot works.
Any other roms stuck on LG logo.

I dont understand it even more. Could i downgrade to a 2.1 version with all the old function? And what's a modified ROM? And what happens if i follow your commands a what should i do next? Sorry, but like i said: I'm not a pro in things like this.
Yes you can downgrade from 2.2.1 to 2.1
Process have two steps
in first step you enter fastboot and enter command
fastboot -w
now when your data are wiped pull battery , put it back, press down vol + power to enter into download mode, and flash with any fastboot 2.1 rom.
I didn't success to flash original rom, so I assume you will not succeed also
When I flash original rom, LG 540 stuck in first android animation.
But with fastboot roms, LG540 work perfect.
And where did i get a fastboot 2.1ROM?

since you say this in first post "A few days back, i updated my phone to cyanogen 2.2.1" you already have fastboot rom

But where? The only fastboot ROM i have that i know is the one i have on my phone. And that's 2.2.1
Or am i wrong?
EDIT: or did you mean to update it in fastboot?
And is it possible to use both ROM's the same? So that i can choose which ROM i want to use without up- and downgrade again and again?
Look you must have had a kdz file that you used to flash 2.2.1
Sent from my GT540 using XDA App

fastboot rom is modified rom
but thing that all of us use is clockwork recovery ( home + power)
From recovery you can make restore and backup.
You enter in fast boot
fastboot -w ( to erase data files and cache)
then install new 2.1 rom via fastboot options
reboot LG 540 and voila , you have downgraded your phone.
When you all setup in new rom, go to home + power, make backup of system and then you can change systems by using recovery in clockwork recovery.
So you can have many backups, bat cannot have two active roms in same time, only one.

So after type fastboot -w i can instal the Original v20__A 2.1 LG ROM. And can i make a backup from 2.1 and 2.2.1? And use them both without change ROM?
PS: I haven't seen any clockwork after i let him update. Is that right?

YOU CANNOT MAKE BACKUP OF ORIGINAL ROM.
You can only make backup of modified roms.
But since I , and many other cannot flash original rom after flashing any modified rom I gues that you cannot also.
When you wont to flash original rom then you not need to use fastboot -w , since KDZ updater or original LG service tool will do it for you.
Clockwork is rom like any other. You must flash also recovery image, and then when you power up LG 540 with combination HOME + POWER and then you will see it.
Market
Okay. Sounds maybe crazy but after update, i LOVE 2.2.1 . except one thing. my market is 'unfortunately stopped'. So does anyone know a thing or something to fix it, or an other market? thanks in advance

You're welcome and thanks for offer
every version of "HuaweiUpdateExtractor" which i have found, did not work for me! Because the PLK-L01 is missing in the device selection setup! Please can you give me a link off a working Extractor?
BTW: isn’t it enaugh, to solve the above described problem to flash the ori. recovery with fastboot or adb?
i would try:
1.) connect the phone to pc
2.) open the communication to the phone using adb-tool v1.0 ore otherwise with the command "adb
devices"
3.) flashing the recovery with "fastboot flash recovery.img"
4.) and than restarting the phone with "fastboot reboot recovery.img"
ore otherwise
4.) reboot the phone with pressing the 3 right key simultaneously longer than 5 sec. to restart flashing the update.app file.
is that way wrong? Please explain.

hey there, someone with better experience than me will surely help you out a lot better, but i can guarantee that the 0.9.9.3 release works
just leave "unknown (worstenbrood)" as profile, pick your update.app file, unpack it
personally i used the b121 rom, and flashed it on my phone with adb, more or less as you described, loading both recovery.img and system.img from update.app... "fastboot devices" > "fastboot flashrecovery recovery.img" > "fastboot flashsystem system.img".
this did the trick with me
at my first try i get only more than 25 nameless files! So i thought the procedure miss.
so my question now, how will they get there names? Than’ks for your reply.

Try to extract only these 2 files (system.img and recovery.img) separately.
For those who will kill their phones without backups:
1. you need to extract boot.mg (usually 10.boot.img) and system.mg (usually 14.system.img)
2. Somehow get into fast boot mode (from TWRP reboot>>reboot into boot loader
3. Connect the phone to the computer and (using platform-tools from Android SDK) from terminal:
fastboot flash boot 10.boot.img
fastboot flash system 14.system.img
fastboot reboot
The version of the ROM is of no importance

Charge it for a day, then press vol + button and power button and see if you can get to fast boot. Try plugging USB in and see if it's recognised, otherwise.

Boot your phone into fastboot first. Connect it to your pc. Make sure you already installed adb drivers. Then extract the downloaded rom. And finally, run flash_all.

Why to flash twrp. Flash stock recovery via fastboot command. Download stock rom, put it in to internal storage. Now boot in to recovery. Update phone from there. This method will work.

Hi, I'm currently on Weebprojekt android 11. Came from pixel experience plus 10.
I wanna go back to stock miui but everytime I go to fastboot it's just a black screen.
Then when I'm using miflashtool I have a problem where it keeps telling me it can't catch checkpoint.
Any help would be appreciated.

Try to flash latest firmware first or try with latest version of miflash tool.
on your PC, unzip the installer zip, and then zip it again. copy this re-zipped ROM to SD card and flash it.

Just try flashing miui recovery rom using custom recovery (orange fox recommended). Then try flashing it with mi flash tool (if you really want this method). If still issue exits, try extracting the rom file again and try flash or else download a fresh file. And one more thing....if you want a clean miui experience without lag and good battery, I recommend you trying miui eu rom 10.3.4, its an old version, but really good. Netflix is not supported. I really recommend eu rom as it is free from bloatware.
