LG2X and CWMR = loop boot on LG ...!

[Guest boezio]

Hi, greeting to all, it's my first post (7 days since my start in Android world, thanks to wonderful LG2X !) and i hope you can help me in some little questions about this device (please forgive me for my bad english).

1) loop boot.

I've installed with Rom Manager the last clockworkmod recovery (all ok and no errors), and i made a 10b-stock-rom nandroid backup with CWMR recovery boot.

After some "gaming" with the device (i've installed Cyanog nightly to test my BT keyboard: with Froyo was stuck, with Ginger it started like a flash ...!), I must revert to original rom because I use the device for work and I must have working PC-suite service to sync Outlook and LG2X.

So my idea was "yeah, in a bunch of secs, with cwmr restore, i will have again the device as was before"... but is wasn't so ... :-(

Procedure seems OK (before restoring i made the suggested 3-pass delete with CWMR), but after it my 2X was loop stuck at the LG start screen (2-3 seconds with the bottom bar moving, then nothing ...).

So i searched everywhere and i found the fastboot-nvflash package, which (apparently) have unbricked and reset my smartphone to factory setup.

But I've tried many other times: I could not backup/restore no type of FW, because backup is OK (no error messages), restore appears OK (same thing), but when device must boot, it remains loop blocked-bricked at LG screen.

So i spent two hour to rebuild my LG2X with all settings and apps from stock rom 10b, and if i cannot make a safe backup (and, most important, a working restore...!) i will not install any FW anymore... i can't spend my days in rebuilding manually the system another time (my wife could kick me out of home... :-( ).

Is there some trick i've missed, or i'm the only in the world who can't use nandroid-clockwordmod recovery...?

Every help or hint is welcome, thanks in advance.

2) factory reset (or not...?)

I read some text about the above fastboot-nvflash procedure: they say the system is able to "factory reset" the device, because it will overwrite all partitions.

So, I would ask to you if the above statement is true, because the flash.bat contains this command:

.\nvflash.exe --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --setbct --odmdata 0xC8000 --configfile android_fastboot_emmc_full.cfg --create --bl fastboot.bin --go

But the folder contains the .img of boot, recovery and system; the folder created by CWMR contains instead the .img cache, data and nandroid too.

If i want to do a totally-factory-reset with the stock rom, is enough the above command or I must make something else ?

I'm asking this because I read of ext3-ext4 conversion problem (i've installed the Cyano nightly: is an EXT4 ?), and i was not sure that my system bricking after restore isn't dependent from this.

Sorry for my bad english, I hope i've explained my doubts.

Thank you for every help. Alex

If you do a restore of the stock rom, and then flash a custom rom which changes the file system to ext4, then you CAN NOT restore the original backup again. At least not until you have restored the file system to ext3.

Hi! In fact, I restored the 10b stock with the nvram procedure to avoid filesystem problems, thinking that system will fix any filesystem issue (since nvram writes .bin files, i.e. a binary 1:1 copy, into flash... is it the correct way?).

But if i install stock rom 10b with nvram, then Rom Manager and CWMR, and then i'll make a nandroid backup with the recovery boot tool, when i try to restore this backup, I'm hung at the LG boot logo... and i must nvram-restore again... :-(

I did the same and I got exactly the same problem. The only backups I can restore are the MODACO Roms.

Here is what I did:

1. Installed ROM Manager wi CWM
   
2. Backed up the original LG ROM
   
3. Installed/flashed MODACO FR13
   
4. Re-flashed original ROM from MODACO given here using NVFLASH
   
5. Re-installed ROM Manager with CWM
   
6. Tried restore original Backup (LG ROM). Hangs on Boot Screen.
   
7. Tried Restore FR13. No problems

Hey guys,

for this Paul have done a ZIP package to convert EXT4 to EXT3 from the recovery.

http://android.modaco.com/content/lg-optim...r-back-to-ext3/

When you want to revert to a stock rom no need to nvflash, just use that package first and the retore your stock backup.

Same problem here but only with restore Stock V10c. I also installed 2 Modaco Roms and then i want back to Stock Rom. So first i use backtoext3 and then i restore my V10c backup, no erros but after finish, it still hang at LG logo :mellow:

But i can restore my first backup from V10b, only 10c failed...

I could not restore neither the original v10b: if I use CWMR -after full nvflash with the above flash.bat- to backup the original v10b, then I restore this backup, I'm hung at the LG logo..

Ideas:

1) Is it possible that CMWR has some (unknown) issue with some type of O2X phone, or with some phone configurations ?

And again my question above: there is a way to restore ALL the phone as it was at the first power on (a.k.a. after de-enveloping it in the car parking of the store where you've bought it ...? :-) )

2) Is there any other recovery boot rom (i've heard about Amon-RA) working on O2X, to try if something changes with a different backup tool ?

Greetings to all in the forum!
