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?

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

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

hey guys i'm having some trouble. i just got the nexus (it's my first smartphone, ever) and i've tried to hit the ground running. here's what i've done to the phone so far.
i got all the drivers running on my win7 machine and also installed the android SDK folder onto C: as was described in this thread: http://forum.xda-developers.com/showthread.php?t=878786
i then unlocked the bootloader using the above guide as well. when I power on the phone using UP+POWER it says UNLOCKED.
I then proceeded to follow this guide: http://forum.xda-developers.com/showthread.php?t=875875
i used ADB to flash the clockwork crespo recovery. i then used fastboot to install Superuser.
at that point i had an unlocked bootloader, clockword recovery image and superuser permissions.
i then saw that the 2.3.1 update had been released. i wanted to learn how to tackle that so i started reading up. i noticed that people were using ROM Manager and Titanium. I got titanium and installed the BusyBox addon and it allowed me to do a full Batch Backup of all my programs, etc. i've got the 50MB or so backup folder on my PC now.
anyway, i then messed with Rom Manager. I installed the 3.0.0.0 ClockworkMod Recovery and everything went smoothly. now this is where my troubles begin.
when i go to Download ROM all i get is a Free Stuff area.
when i go to Check for ROM Updates it tells me my device isnt set up for OTA updates.
those are just minor issues.
this is the big and scary issue i have:
when i click on reboot to recovery, it takes me to the same screen that i go to when i power on with VOLUME UP+POWER. it doesnt take me to the recovery screen that i see in various youtube videos. instead, i'm at the main screen where it says UNLOCKED and i have 4 choices (reboot bootloader, recovery, reboot, power off). and on the very top in RED letters it says fastboot - no boot or img file. <-- this is the part that makes me nervous. If i manually power down the phone and boot to fastboot and click recovery, it just goes back to this same screen and says fastboot - no boot or img file. when i first rooted the phone, clicking recovery actually took me to a different screen where i was able to load up superuser.zip and install it.
did i accidetnally delete something that i wasnt supposed to? did installing ROM manager mess something up? i typically dont do anything until i confirm that i am supposed to. i think the problem is that i dont yet know how one thing i do on the phone affects another. i'm guessing when i used rom manager to update the CWmod it changed some folders/files? i dunno!
otherwise, the phone works fine and there are no glitches or hiccups or crashes. So if someone can please take a moment to just explain to me what i did wrong or what i failed to do i'd really, really appreciate it.
you don't have a recovery partition. Either flash one over manually using fastboot, or boot up and try to use ROM Manager to flash CWR.
when you say flash one over using fastboot, do you mean put my phone using VOLUME UP + POWER, connect usb cable, then use command line to do this:
fastboot flash recovery recovery-clockwork-crespo.img
?

Yes, 'cept it will be "fastboot flash recoveryrecovery-clockwork-3.0.0.0-crespo.img" without the quotes now.
But does it say that you're missing a boot.img or recovery.img?
Also, the "not set up for OTA" thing isn't for official OTAs. Some developers have made their custom ROMs capable of being updated that way.

thank you luxferro and unremarked. i did it and it works perfectly. i am now able to access clockworkmod recovery 3.0.0.0. next step is backup my existing ROM and also to figure out how to put the OTA 2.3.1 on and restore all my data
oh and unremarked: it basically said no boot or img file and thats it after i would click on recovery or reboot to recovery trhough rom manager. it was just in red at the top. but now it takes me to the ClockworkMod Recovery
Hi guys, I'm a newbie. I wanted to know, how can I flash my os from 2.1 to 2.2 .
The main problem is - I dont understand how does the fastboot works. there are img. files. What should I do with them ?
THANK YOU VERY MUCH FOR YOUR USEFUL REPLIES!
do you have rom with fastboot?
do you have fastboot already installed to your pc ?
when yes ,then run these command on androidSDK :
Code:
fastboot.exe flash system system.img
fastboot.exe flash boot boot.img
fastboot.exe reboot
but when not :
you have install AndroidSDK and fastboot items and gt540 drivers.
how can I install fastboot rom ?
I read some information, got the links, but I dont understand how to get that rom on my phone.
I understood, that i will have to reflash my rom, cause I have 2.1B baltic, and there's no fastboot on it. Is there any chance that I can install fastboot seperatly?
Look when you reflash with another 2.1 you wont notice anythings changed. It keeps your data. When done just turn phone off then switch on with power and camera held together until a blank screen. Thats fastboot.
Plug phone in whilst on black screen then follow the fastboot instructions in 2nd post

I installed a fastboot ROM, then installed the openswift 2.2 ROM last night, and fastboot mode was hold volume up + search while powering on on my gt540f. Camera went into download mode for me.
ok so i wanted to flash clockwork 3.0 but i was still running cm 6.1.1 and now i am stuck at the htc boot screen. i also cant get into recovery please i am begging for help.
please someone i really need help i obviously cant use my warranty obviously so please help me restore this or just get it back to working without a root anything
Dont worry pal.
OK,... AFAIK...... If you have flashed ClockworkRecovery 3, the only ROMs that will work are the 2.3 ROMs,... If you are trying to boot up a 2.2 ROM, it is likely to bootloop.
So boot back into recovery, full wipes, then flash a 2.3 ROM,... If that is what you were planning to do.
If you want to keep your 2.2 ROM on,... flash back to an older Clockwork Recovery,... then try to boot? If you get boot loops, try wiping cache and try again. If it still fails I would just do a fresh flash of your ROM again,... Remember full wipes 1st.

Can you boot into Hboot screen (phone off then volume-down + power)? If yes try to select recovery from the Hboot screen, it should reboot into recovery, if it doesn't and something is wrong with your recovery, Do you have an Eng. Hboot? , if yes do you have Andriod SDK set up and fastboot? If yes, boot into Hboot, select fastboot from the options, then plug in your usb. Once your device is recognized by fastboot:
Code:
fastboot devices
should return a serial number + "fastboot"
then reflash ClockWorkMod Recovery 2.5.1.3( you can download it from here:http://www.koushikdutta.com/2010/02/clockwork-recovery-image.html then place the ClockWorkMod Recovery 2.5.1.3( make sure its named recovery.img) into the tools folder in AndriodSDk where Fastboot is located, then run the command :
Code:
fastboot flash recovery recovery.img
fastboot reboot
once rebooted your probably gonna be stuck at the HTC screen again, pull the battery, then Volume-down+ power back into Hboot, then select recovery from Hboot screen and it sholud reboot into ClockworkMod recovery, then reflash the rom of your choice.
thanks but i already fixed it by pressing sim lock and i have no idea why that worked and i should probably set up adb now right?

Hello everybody!
Sorry to be the noob, but one must start somewhere before being a decent user!
I give you quickly the background: First I flashed the phone with the European version rom with flashboot in it.
Then I installed Froyo by Ankuch and Quarx through flashboot
And after this I installed Gingerbread by Mur4ik thanks to the exe made by eoghan2t7 in flashboot mode.
I read many times about clockwork recovery, however I do not have the impression to have came accross a specific version of the firmware such as the European version rom. Would it be by any chance included in Cyanogene Android by Mur4ik? I don't think so unfortunately!
Other question: What is best, recovery or flashboot? Apparently recovery is safer, and it would not be a bad thing given my computer savviness level ahah!
Thanks in advance!
Nevermind, I figured it out, if somebody needs help and I can be useful I would be more than happy to explain how I did it despite my weak level in computers.
Or I can explain it here for you, Fastboot is apparently more easier, if you had a usb connector from your phone to comp, because, you're gonna connect it to the PC anyway, so why not just do it on the comp?

Thank you AntonJrL for your support! Now I thing I got it though.
The line between fastboot and recovery was blurry for me, I thought it was a different firmware than the one I installed for fastboot.
Now I figured out that the recovery mod was inside the pack with the 2.3.3 rom and I flashed it on my phone. Now I can reboot in recovery mod so I will have to worry less about bricking my phone
Jasper580, do you want the file for flashing recovery in your phone?
Hi, i prefer fastboot because is easier. You just have to download the ROM in your puter then plug your phone in fastboot mode,copy the .img files into /tools folder then open the cmd type few codes and voila you have flashed your phone.
cheers!
I too prefer fastboot over recovery,
I've never had a problem with fastboot but in recovery I get MD5 mismatch.

hey mimm.m nice to see you here
it's me michabilbang.de
back2topic:
i've done both ways, via recovery mod at my first time with swiftdroid 1.8.
If you restart your phone in recovery mod or fastboot, it's not much difference, at recovery you do it with your phone, at fastboot via pc.
But i prefer fastboot, i just have to run a bat file and it puts all on my phone.
i use fastboot but i dont like it, ive bricked my phone a few times with it.
recovery is very easy! and not need a computer with full driver

Fastboot VS Recovery
Fastboot is easy but i needs the computer everytime you want to change ROM.
Recovery on the other hand also needs your computer to install clockwork however once installed you have the convenience of changing your ROM as often and anywhere you like as long as you have the .zip file on your SD card.

Normally installing stock ROM will cure most things unless you have internal issues.
Flash stock recovery.img for the stock ROM you want to get back to... I would suggest 360. You should already have downloaded the stock ROM update.pkg file that corresponds to the stock recovery.img you flashed in fastboot. Make sure you don't have any other files on the root of your SD that conflict with you update.pkg and MOST importantly, make sure it's named "update.pkg"
Boot into recovery and choose option 2 to update. IF it gets stuck (now this first boot after installing stock ROM may take 20 minutes or so), then pull the battery, boot into recovery, and choose to do a factory reset again
Hi guys
I'm hoping somebody could please help me with my somewhat-bricked device..bricked in the sense that I don't know what to do with it. (i'm a noob to this). I've tried installing a custom rom and completely screwed up my dell streak 5.
So the phone doesn't boot anymore and just takes me to the option to install update.pkg off the sd card. I added the file along with recovery.img to the sd card.

My problem is that I cannot for whatever reason get Flashboot to work in order to flash the recovery.img first. under device manager you see android phone/android adb interface but still can't manage the connection to use cmd prompt/fastboot.
Is there any other way of getting the recovery.img to work without fastboot/thru the sd card. I have no idea what i'm doing anymore. I've tried installing the update.pkg but after installation it just stays on the dell logo loading screen forever.
PLEASE help if you can.
