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.
And I wont original flash procedure from LG ( from windows)

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,
We have a problem with an Optimus 2X.
1. We rooted the phone
2. Installed ClockworkMod recovery from ROM Manager (Flash recovery option). Successful window appeared.
3. We boot in recovery mode from ROM Manager.
The phone now hangs on boot at the LG Logo. There is no way to boot in recovery, and there is no way to do a normal boot. (Tried to boot with volumen down and lock buttons pressed, and without pressing volume down...)
It's like there was a flag that forces the phone to "boot in recovery" or something like that.
So we can't boot the phone in any mode...
We also tried smartflash, but nothing...
Any idea? How can we restore it?
Thank you very much in advance...
I would try the procedure at this link: add "http:" infront of my links, for some reason i'm not allowed to post outside links.
//android.modaco.com/content/lg-optimus-2x-2x-modaco-com/335474/25-mar-nvflash-stock-rom-release-v10b-dated-1300166062-15-03-2011/
It uses the nvidia flash tool and will allow you to flash a clean stock rom without booting up the device or going into clockwork.
The stock rom version that you can download on the link above will do fine. After you've flashed the stockrom you can reinstall clockworkmod. If I were you I would do that using these instructions:
//android.modaco.com/content/lg-optimus-2x-2x-modaco-com/335479/10-may-3-0-2-8-clockworkmod-recovery-for-the-lg-optimus-2x/
Basically all you need to do is attach the phone to the computer, make sure usb debugging is enabled and double click the install clockworkmod.bat file found in the extracted zip file downloaded from the link below.

After that you should be able to flash all the custom roms you want. I hear the latest Cyanogen nightly is pretty stable!
I had the same problem and question a couple of days ago...
Mine also when trying to install CWM..
Follow this link and flash with NVflash and You should be good to go again
http://android.modaco.com/content/l...rom-release-v10b-dated-1300166062-15-03-2011/
I also gave up on the CWM flashing from PC and paid for this app in the market:
https://market.android.com/details?id=com.modaco.twoxrecoveryboot&feature=search_result
Its .99 pence so not to bad... remember You NEED ROOT for the CWM recovery flashy thingy
After all flashing I just went with the stock ROM with the 0606 upgraded baseband
Works ok now (flashed with smartflash)
The 0606 baseband ROM can be found here:
Happy unbricking!
Thank you very much to both!
NVflash did the trick and I could fix the full brick!
Now I don't fear anything... nvflash can resurrect it!! xD
Thank you very much!!!!!
THANK YOU SO SO SO SO SO SO MUCH GUYS!!!!!!!!
i was messing about for about 5 hours because my apx driver didn't successfully install but i finally found one and got it to work.
i am so relieved. I can sleep easy tonight
once again a huge thanks.
Hello experts,
After CAREFULLY reading the instructions to root and install Cyanogen on my X2, I have run into a problem. After downloading Rom Manager from the market, I installed CWM, which worked fine.
Going by the instructions, I wanted to ensure I performed a NANDroid backup of the stock ROM, 'just in case'. So i did.
After confirming, and granting 'su' privileges, the phone restarted, only to be stuck on the LG logo.
Holding down VOL DNW + POWER is no help, as the phone was still stuck on the logo.
I don't understand what I have possibly done wrong, but none of this was stated in the wiki so I am assuming i'm in a unique situation?
After some googling:
> I have read that it may be from CMW converting to EXT4.. whereas the stock rom can only run in EXT3? .. android.modaco.com/topic/336318-4-apr-r1-backtoext3-for-converting-your-device-er-back-to-ext3/ ..
> All hope is not lost as apparently, I can flash to stock rom using NVFlash: .. android.modaco.com/topic/335474-25-mar-nvflash-stock-rom-release-v10b-dated-1300166062-15032011/ ..
Ok, so I understand I have a possible solution to my problem (NVFlash), however I would like to know why this happened & how I can avoid it from happening in the future.
Thanks for your help in advance.

NVflash is a built in safety system by nVidia, it has nothing to do with the recovery image. You should be very careful with NVflash, because it's very low level and even the slightest mistake could brick your phone.

This is the NVFlash Cleaner for SU660
the LG official V30C firmware of the SU660 have different partition layout
so If you want to install the CyanogenMod 10 official Nightly build on to your ICS installed SU660 device, you have to rollback to the GB firmware to make it compatible with CM7/CM10 using smartflash or nvflash.
This NVFlash Cleaner helps rollback your ICS firmware to GB.
but all partitions will be ERASED, the old GB bootloader restored and the CWM5 will be installed onto both the boot and the recovery partitions.
The size of the NVFlash cleaner is only about ~5MB!
Cautions
●before using the NVFlash Cleaner, backup your device and copy backuped files into your PC.
●The internal storage will be erased, you have to format your internal storage before use it.
Procedure
1. Prepare APX mode.
2. run flash.bat to format your phone.
ChangeLog
● CWM5.0.2.8e update : support changing font

Thank you very much, this will save ICS user a great length (smartflash back to GB, root, install CWM) now just a click. But I heard aragorn said you have a kernel already. Pls release it - thank you very much. You seem of the highest technical level on SU660 side. Tks again

extract it. and you will have a .bat file. now connect your phone to computer in apx mode (by plugged the cable in when holding volume up and down keys). you should see your computer show apx device connected. then run the .bat file!
How to prepare APX mode? I dont have the drivers either
hey wkpark, do you have a O/C kernel for stock SU660 ICS? :good:
just tested the flash.bat under APX mode (s/w upgrade screen with battery out and press volumn up&down), it is not going anywhere.

You'd better to use the Smartflash cleaner. It's more faster and easier then the nvflash cleaner

wkpark. I used the smartflash cleaner to wipe the partition, then install stock ICS and rooted (used Unlock Root), but I still can't boot into CWM?
tried "power+volumn down+home" method, Red LG logo -> the green android guy with neutron stomache ....and boot straight into ICS
also tried rom manager -> "Reboot into Recovery" and it won't work either, it shows the green android lying with red exclaimation mark not going anywhere.
Am I doing it correctly? What should I do?

Red LG logo?
The Red LG logo means you got the newer ice bootloader, seems like you''ve changed your bootloader or the smart cleaner is not correctly packaged by mistake
I will check the bootloader as soon as possible.

the NVFlash cleaner or the smartflash cleaner only for the old GB bootloader
and for using the old GB/CM7/CM9 firmwares!!

v0.6 is out with the newly updated CWM5.0.2.8e
Do you have another way to install CWM? Such as install from SD card? My USB port was broken, and I can't install CWM via APX :|.
OK I am new to using LG's and so far it seems a lot more involved vs the Motorola Droids and Samsungs i've worked wtih. With that said, I AM A NEWB and might have bit myself in the rear.
So I obviously did something wrong... I thought I followed the process meticulously :crying:. Now I cannot mount the /emmc and /system on the internal storage since running nvflashcleaner. What did I do and how do i fix it lol. I downloaded v 0.3 and it wouldn't see the port for the phone. so I d/l'd 0.2 and had the same issue. 0.1 did the wipe no prob but now i'm at a brick wall. I downloaded Gingerbread from LG's site but no good if I can't access the system and the backup I created got wiped off the SD card (i accidently wiped the card) So needless to say, i'm having a bad day even after work LOL. I've got to have this up and running by saturday or i'm going to find myself buying a cheap android to get me by til i can figure this out (a friend already paid me for my existing phone when I got this one on ebay...big mistake I think) any ideas are greatly appreciated!!
*edit* I must add - I am trying to use CWM Recovery and it just hangs at "Nvflash started"
OK I found one download with nvflash that was listed for an SU660 but ended up being for the P990 LOL. outside the touchscreen not working, It booted up to the OS so thats a start. so with that... just have to find the Froyo OS or Gingerbread I can get working on here

hi wkpark
Thanks for doing this!
Unfortunately, I was unable to format my internal sd card from within cwm, and I don't know how to do it with my computer. I ended up being stuck with cwm and a bootloader without being able to transfer any rom zips to my phone. SO, I used this thread to help me roll back the old way. This should help anyone who is in a similar position.

When using Smartflash tool, you should be on "Download mode or SW mode" (Turn off phone, pull out battery, run Smartflash tool, hold Volume down and insert USB cable from PC. wait until Smartflash tool detects your phone)
In nvflash, you should be on "APX mode". Before going APX mode, make sure you installed the APX drivers first. Then turn off phone, pull out battery, hold Volume up and down then connect USB cable. wait until PC detected the device as "Nvidia USB Boot-Recovery" in device manager or APX device in notification bar.
Hello guys, I have a problem with my LG P990 , I tried to upgrade the android version using only the phone(looking automitaclly for updates) [Everything started from 2.2 version] , nothing found, I tried with lg mobile support and I did to 2.3.4 or something after that when I tried to update again it failed so what I did ? I had used the AIO-toolkit without knowing anything, anyway -/+ went in CWM recovery menu , did some scarry things there after I saw that its not any chance with all that options I went to youtube and saw what should I do ...
So.. I used usb storage, I dwnd ROM, gapps and supersu , installed them in that order , reboot system now, everything was fine and then again to CNW menu , then again .. and again CNW menu , and yes, I'm blocked there ,in the menu. What should I do ? I tried a lot of things, taking out the battery , used another rom , using - and + again doesnt work so im done.
If anyone has any idea would be great to hear your ideas, thanks and have a good day.
CNW-based Recovery v6.0.2.5 , btw.
You could still be on old bl while flashing new bootloader Roms. More info needed, such as rom you tried to flash, your current bootloader (pink or white lg logo at startup).
Sent from my LG-P990
I tried cm 10.1 , after that I tried cm-10.1-20140112-NIGHTLY-p990.zip , which is the last one but didnt worked , supersu v1.25 . about logo .. its not pink , its just a normal LG logo ( that rounded logo((its kinda red, not pink)) in the left and LG near it ) .
If you want more info let me know, I dont know many details about phones and systems.
btw, after I'm installing rom,gapps and supersu ( I tried without supersu too) , I go for reboot system now it says S/W Upgrading and after restart its back on cwm menu
Ok, firstly you should try flashing never recovery (latest twrp or latest cwm by misjudged (both could be found on xda)) then you can try flashing roms. Are you sure you have p990 not p999 or su660?

Yes I'm sure I have P990 , what about never recovery? should I download cwm or latest twrp ?
It's up to you really, both do the jog
Sent from my LG-P990
yea , but I don't know exactly what you saying about never recovery ? It's something to install from cwm menu ? or its an option in menu( in advanced options or something) . I'm noob.
Well, you have to install new recovery. You could do that by installing newer recoverys zip in the using the old recovery (just flashing the zip like you would flash the ROM or gapps) būt i can't say whether your version of recovery supports other recovery flashing. The other way iš using aio toolkit, option 2.

Anyway it worked to change the version but from this version I can't install any rom , cause of Error Status (7) or something like this, I'll still trying and edit my message.
btw, I cant use option 2 with nvflash , just with ADB , cause now my phone not working when I press + , - when its without battery and plugged in , yesterday it worked when I started to ''destroy'' it.
It worked ! I did it with SlimBean rom and gapps from this forum , 4.3 version . I don't think I wanna try again and change to new one, dont like this one , its nice but not perfect, but its ok, its working. Thanks for all your help.
