Hello guys,
I'm hoping to get some help here, since I've lost 2 days trying to flash my phone with a custom ROM.
The phone was running Official Android 4.0.4 Ice Cream Sandwich V30A, and I did the following in order to flash it:
After unsuccessful rooting attempts with SuperOneClick (stuck at step 7) I found another way, using nvflash, following these instructions. Somehow I thought I need to unlock the bootloader first, in order to root the phone, so I did that first. After that, I rooted my phone with SuperSU Root as described in this tutorial, and also installed CWM.
I thought that I was ready for the flashing part, and downloaded a custom ROM along with the right GAPPS, and followed the instructions carefully.
First few attempts I got stuck at the beginning of rom flashing process, than I found a solution, where I needed to delete the first line in the META-INF\com\google\updater-script file, then the flashing came trough, but somehow to quick I thought.
After everything was wiped/cleaned/flashed I click on “reboot system now” after which the phone should reboot into the new rom, but nothing happens, the phone acts "dead", it won't turn on, or boot into recovery mod. I was sure that I've bricked my phone, but luckily I was able to get it back on using the APX method with nvflash and boot flash.
But then the phone starts with the official ICS 4.0.4, as if nothing was flashed.
After another day of searching for a solution, I've found out that there are different partitions for different rom's, than I realized that I was trying to flash
Android 4.2.2 Jelly Bean on LG Optimus 2X via Avatar Custom ROM
LG Optimus 2X P990 to Android 4.2.1 CM10.1 Jelly Bean Nightly
Jelly Bean on a ICS device wich logicaly should run on a different partition, so I downloaded a ICS based ROM EAGLESBLOOD™ ICS "AOSP" 4.0.4_r2.1 and got the same issue when flashing, where I had to delete the first line in META-INF\com\google\updater-script, but than the flashing process went trough and seemed more genuine than before as it took longer to finish, so I was happy for a moment, and rebooted the device, and voila nothing...he's deaaaad again.
Can someone please help me to find out where the problem lies.
Thanks for any help, I hope someone takes the time to read this.
No one here to help...
Finally I've managed to install TWRP over CWM with AIO Tollkit, to see if the problem was with CWM.
The flashing process/time seemed similar, but the phone actually booted this time, but not into the new "flashed" custom ROM, but into the old stock one which should be wiped/deleted...
Dont worry too much....
Just use the All In One Tool Kit by spyrosk.....just wipe everything....as I suspect that all your partitions have been disturbed.....for the link for this tool, check my signature
Flash the one from JellyCream.... (it is new bootloader ROM on the dev section) or if you want the 4.3 based CM ROM, then find the one from tonyp....
You will loose the data on the Internal SD card....if you have a backup on the external, then restore form it....
Edit: Eaglesblood ROM is not supported by the developers as far as I know....
Finally
Thank you for replying/helping :good:
As it seems, it was a bootloader issue (ord/new). My phone has the new one, and I thought that the ROMs I've downloaded
Android 4.2.2 Jelly Bean on LG Optimus 2X via Avatar Custom ROM
LG Optimus 2X P990 to Android 4.2.1 CM10.1 Jelly Bean Nightly
EAGLESBLOOD™ ICS "AOSP" 4.0.4_r2.1
would run with the newBL, since they ware recently updated or made, and there was no clear info about the boot loader version.
Now after 3-4 Days of struggling, I've tried a ROM which is made and clearly stated for the newBL,ParanoidAndroid v2.6 "p990-2.6-14-newbl-tonyp.zip" and flashed it without any problems. I didn't have to wipe the whole internal storage with AIO Toolkit, I've followed the usual flashing procedure.:victory::laugh::good: the new rom looks awesome. I hope that I won't have any lock screen or random reboot issues, like before.
Now I'm gonna help a guy, who has the same problem.

I've been trying to Change the ROM in my phone all day and I've had no luck.
I first tried Slim Bean and that worked no problems BUT...
I had a blank IMEI which means I cannot make calls and I also learnt that you can't go from GB to JB, you need to go in steps of each ICS
I think If I go back to 2.3.3, copy or back up the /efs files or something then go back to Slim Bean then copy them that MIGHT work but I haven't tried it.
[Would be nice if SlimROMs just kept Play Store in the Rom, it would make things easier but they don't call it slim for no reason!]
So I went back to 2.3.3 using an Ezbase Recovery and I've been trying to Install ICS ROMs and they have ALL failed when installing causing a boot loop.
I've tried Cyanogen 9, 9.1.0, Slim ICS and a few other I cannot remember.
Is their something I am missing? a certain kernel? Need to upgrade to 2.3.6?
I really just want to get to Jelly Bean, I've tried it first hand Via SlimROM and it's like BUTTER but It's useless at the moment if I cannot get my IMEI or network provider showing up.
Thank you in advance.

ok, for upgrades from GB to ICS, you need a 2.3.6 bootloader, you can use Ezboot without changing ROM ( link in My Android collections) and a CWM by flashing a semaphore kernel. Here you backup your EFS.
In ICS ( follow guide by developer of your chosen ROM) , you may need to flash twice, as first flash may give you boot loops
Worked like a charm.
You've been so helpful since I joined XDA.
I wish I had money to spare for the help but I massive thanks is all I can give at the moment!
Hello friends of the Optimus Black.
[Introduction]
Today i started the first time flashing and android phone. Before i modiefied & flashed firmwares of serveral AVM fritzbox devices to get more features. I use linux as my everyday OS, but installed Win7 because it seems to be easier when working with android devices.
[Problem]
My LG OB stucks at the bootscreen (flying rocket) after i installed the jellybam_p970.NIGHTLY_20121215.zip and gapps-jb-20121011-signed.zip.
I have used theese instructions:
[HOW TO]The Big N00B how-to! and [ROM 4.1.2 - 4.2] JELLYBAM [15/12] [Nightlies] [P970] [PA.AOKP.CM10] [ATOMIC] .
I do know how to handle the SmartFlash Tool to get bricked phone back to live.
One problem is, that iam not shure, if the used nightly rom is corrupt or if i may have used the wrong gaps file. I had to opent this thread, because iam not allowed to post in the developer section (which might be good, if the rom is corrupt)
Another problem is, that it id like to avoid a further unbricking-process with smarttool, just because it takes so much time to:
1. unbrick
2. turn on usb-debug
3. use blackjack to root
4. connect to wifi
5. register at google
6. install rom manager app
7. backup
8. factory reset (wipe)
9. flash
Is it possible to take a shortcut?
Many thanks for your help guys.

Hopefully, there is faster way ! After more than 20-30 bricks i get bored with similar process to yours ;p
You just need to use THIS tool to convert your favourite stock firmware to smartflash format and patch it with CWM (recovery). Then, after flashing this converted firmware using SFT your phone will automatically reboot into recovery and you will be able to flash any ROM without rooting, installing cwm etc.
I don't remember exactly, but this tool should only work with v10-v20 firmware, so just download one from HERE from your country (or just with well working baseband) and let's simplify your life !
I have modified one. Many thanks for this tip. I will test it the next time the device bricks.
Do you know if i used the correct gapps file? I tried Version 10.
EDIT
[Problem solved]
After flashing an earlier nightly buld (14th of december) and the CM10 gapp file the OS starts.
Thanks for your help

Hi,
Sorry if this seems like a dumb question - A bit confused from reading up all the info on upgrading to ICS on the p990.
Im running a volk custom kernel, and CM 7.2 - OS Version 2.3.7.
Whats the "best" way to upgrade to the new ICS? I tried running the LG software update but it doesnt go too well, fails after it tries to detect phone - even though it detects it initially.
Can I get the release that LG released with my setup?
Please advise.
Thanks!
Same situation here. I'm on official cm7.2 and would like to upgrade to ics. But don't think that useing official lg update tool is so good idea - it might brick your phone. It won't update to ics because you aren't running the official GB rom so lg update tool won't upgrade (correct me if i'm wrong).
Maybe the AIO tool would do the trick.
Anyways, people we need your advice!
LOL, use NVflash ICS rom like TG.
for me the best way is using the toolkit to install new partition, new bootloader and recovery
than boot into recovery and flash the room as usual
Thanks Wakata.
Much appreciated. I have tried downloading the toolkit but its always corrupt.. ill download the 7 zip format.
I take it that I will need to back everything up and wipe everything, install new partition, boot loadder and recovery(CWM??), then flash with the new rom and kernel?
I've also used the All-In-One P990-Toolkit to upgrade to ICS.
You can use 1. to backup your internal SD in case you need it later.
Then hit 4. to change the partition layout and after that 8. to flash the new unlocked bootloader. That's all.
Thanks again
Slight problem - I downloaded the 7z file, and extracted them, but cant seem to run the .cmd file? What am i doing wrong here?
scratch that last question.. for some reason the files are corrupt when i download them.. grrrr.
So I followed the instructions, and suprise suprise, I get an error -
Nvflash started
nvflash configuration file error: file not found
An error occured. Read above lines for details
Help please
Nevermind, I had a fiddle and flashed ics 6.0.xxx.. lets see how it goes. Hopefully I havent bricked it lol
Sorry, problem.
I first tried option 1, then 4, then 8.. after its all done, no errors - I boot the phone, and its stuck on the red LG logo.. I've left it there for around 10-15 mins with no luck? Help!
Haha, actually I figured it out. I did realise I didnt have a ROM! Doh! lol rookie mistake.
I downloaded this rom and kernel(1.4ghz OC) and its running pretty well, no bugs so far(touch wood)
For the past 5 hours I have been trying to install P.A.C. MAN 19.0.0 and MIUI V4 for the ICS Bootloader to no avail. I have tried flashing/wiping multiple times to get these ROMS to work, each time with the same outcome. The issue I'm having is my phone keeps getting stuck at the boot logo (the Unlocked LG padlock logo.) I have repeatedly tried wiping Data/Cache/Dalvik Cache like the instructions said. If anyone could tell me what I'm doing wrong it would be a great help, I decided to switch to these ROMS after using the TG V30A ICS ROM. I am using an LG P990 and I am on the ICS Bootloader (not the old GB one.)
Thanks.
Use aio tools and nvflash the ics new partition, it is in number 4 in selection, the padlock logo is the old ics bootloader, the new ics bootloader is have a pink logo

if you've flashed the new ICS bootloader correctly, you'll have to follow this thread (which allows you to flash CM10 based roms on new bootloader - like PACman and new MIUI):
http://forum.xda-developers.com/showthread.php?t=2058231
the only part that applies to you is "coming from ICS unlocked bootloader"
1. you'll have to flash the special recovery (it enables CM10/new bootloader compatibility)
2. then, instead of flashing CM10, just flash PACman rom
*Make sure you flash rugglez' ICS kernel which adds the wifi drain fix, and BSOD fix, unless it's already integrated into the new PACman version!*:

Hi guys, thanks for the replies but after about 7 hours of trial and error I finally managed to fix this.
If, there are any "noobs" out there like me that have these issues, just do what I did below and this should help.
So after several hours of scouring the internet and XDA forums with the hopes of reviving my phone, flashing several ROMS and CWM versions which caused compatibility issues with the ROM I had previously used, and nearly losing my sanity, I had stumbled upon this. So I logged on to my old Win7 laptop (thanks Microsoft, for making Win8 users reboot to install unsigned drivers) with APX drivers and loaded up the program. I flashed a newer version of the ICS bootloader (even though I was already on the ICS Partition layout) and the latest version of CWM. These fixed my compatibility issues and allowed me to flash ROMS again, hurray!
If it isn't too much trouble, could a moderator close this thread since leaving it open is no longer necessary?
And People Please read the instructions before installing (If Provided) .
I've searched a few forums and can't find an answer for my question. I've read that you cannot go to an older version of a rom if you are attempthing to use the fastboot files. Is this true? Can anyone link instructions for going from a rooted 4.2.2 CM10.1 to stock JB from verizon.
I've had worsening problems with my phone through my last few rom changes and I would like to return to stock to see if I should take my phone to verizon for a replacement (the moment I slide the phone open it freezes and the keyboard does not work plus a bunch of freezes requiring hard resets). Phone is running so slow.
Anyways, I would really appreciate a link to some instructions or a quick how to guide as I've used rsdlite, update motorola drivers, fastboot mode, etc before.
Thanks so much guys!!!!!
Safestrap installed CM10.1 is not a newer version of your system technically because it can't modify your bootloader or kernel, it has to use kexec to init a 2nd kernel boot.....so your stock kernel/bootloader are still based on your ICS system.
You can just flash the JB fastboot files and be on JB. You'll need to re-root the device though......and older root methods don't work you you'll need to use the razr_blade script by drjbliss
