[GUIDE] From CM7/MIUI back to stock GB - LG Optimus 2x

I want to go back to stock ROM. Can anyone please explain how I'm doing it?
I'm trying on a step-by-step guide:
1. Flash BackToEXT3 by paulobrien
2. Wipe data/cache
3. Flash stock ROM (and the custom kernel will be overwritten)
Flashed stock V20q, and then updated the phone via PC Suite. For other noobs, that uses this guide later; I now have no root and stock kernel etc., and also updated baseband. Theres now need to use BACKTOEXT3 when you flash stock V20q via cwm.
Is this correct?
Which ROM do I need to flash, where can I find it? I guess I need to download one of these.
I have baseband 622, if that has anythingto do with it

You are doing it ok. If you are using firmware from the link that you are posted, flash it with smartflash. You can flash the version of your liking, however I recommend the latest v20q which is a very good one.
Or you can flash via cwm this stock v20q or Rebuild of V20Q.
v20q baseband is recommended too, with v20q rom.
Hope it helps .

I was going to flash V10d with cwm, and then update via LG PC Suite.
Isen't that possible?
Edit: It worked! Flashed stock V20q, and then updated the phone via PC Suite. For other noobs, that uses this guide later; I now have no root and stock kernel etc., and also updated baseband. Theres now need to use BACKTOEXT3 when you flash stock V20q via cwm.

[Q] [HELP!!!]Bricked my LG Optimus 2x

So i tried flashing a rom with CWM, it all went fine. So i went back to CWM and restore my stock ROM, and i also wanted to get rid of the CWM by flashing Paul's stock recovery:
http://forum.xda-developers.com/showthread.php?t=1021554
Now i can't get back into recovery nor the OS itself. The only thing i could do is nvflash since all i can do now is to go to nvflash mode, my phone is a HK ROM v10A, but all i could find was v10b since Modoco is "re-constructing" its website. So here's the question:
1. i nvflashed v10b into my phone, everything was success, but when it was done, its stuck in a bootloop at the LG logo. I re-flash a couple times with success with no errors, but still the same bootloop. What can i do now?
2. Do i have to flash the same 10A rom in order to get back into the OS?
3. I heard nvflash messes with files related to the phone's IMEI, under what circumstance would nvflash corrupt those files and lose my IMEI?
Yes i m an idiot, but please help!!!!

You download ROM here and use smartflash to restore your phone.
Little Help in Smartflash
Hey , after downloading the required ROM file here n the baseband file from the other link...
Will smartflash use both the baseband n ROM file?
OR
Will it only use the baseband file that is given 2 download
??
One More question i'm running on V10b can i flash directly 2 V10d or i have 2 go through V10c??
Thnx in advance

question before i flash again.

well, i have had some issues flashing my phone to 2.3, and it is currently on continuum v5.5 working fine for a few versions. so i don't want to rush into anything and mess it up again, but i want to try another rom. im a little confused to what all i need to do to get the new phoenix rom on coming from a talon kernel.
thanks!
Just use ODIN ONE CLICK STOCK (http://forum.xda-developers.com/showthread.php?t=731989 and then place the rom of ur choice and flash it in CWM!! tell me if u need anything else
Odin back to stock and follow instructions in the OP for the Pheonix thread.
You need to verify that your current installed kernel is compatible with your new rom of choice.
If not:
1. Find one that is compatible, install it via odin without rebooting - then boot to recovery and install the zip file in cwm.
OR
2. Odin one click to stock and go from scratch.
If going from GB to GB rom then the important thing is the kernel compatibility or you will likely go into bootloop. Other than that wipe, reset and install.

Chinese ICS Leak to Official ICS Query?

Hi all, just need sme advice as I've done a lot of reding tonight but still unsure how to proceed.
I have a UK Galaxy Note, originally unlocked stock Samsung.
It currently has the original chainfire repack of the I9220 chinese leak (http://download.chainfire.eu/146/CF-Root/SGN/CF-Root-I9220_ZC_OZH_LP1-v5.2-CWM5.zip) from this thread: http://forum.xda-developers.com/showthread.php?t=1500186
I'd like to flash the official N7000OXALPY ROM on it now.
My question is, can I use mobile odin to apply the german ICS ROM directly?
I believe I may need to flash a GB ROM first? If that is the case could I do this via mobile odin?
Unfortunately I don't have a nandroid of the GB ROM i was on before to restore (I've learnt my lesson!).
Thanks!

Here is what i did. I flashed N7000CPWLB2--United Kingdom (Carphone Warehouse) using PC Odin, download link from http://forum.xda-developers.com/showthread.php?t=1424997. I then root and used PC Odin to flash the german ICS. I did full wipe afterwards in recovery. You don't get CMW with this approach but i don't need it.
With regards to the second link, do I have an i9220 bootloader now from the chainfire repack? (not sure how to confirm this).
I'd like to follow the instructions from dr.ketan but bit unsure if it's safe?
If you have flashed LP5 Repack then you have i9220 bootloaders ! If you have flashed the LP1 repack then you are without those bootloaders
Hackerboi, its the LP1 ROM. Does that mean I can use dr.ketans guide directly to flash the official ICS via mobile odin, or should I still flash a GB rom with odin first?
I was on TMT 1.0, what I did was flash a direct rootable ROM using PC Odin, root the ROM, flash stock LPY ROM using the instructions on http://forum.xda-developers.com/showthread.php?t=1424997 and that's it.

Flash NOTHING from Repack, be it with Mobile Odin or CWMR.
Use PC Odin to get to GB first. Then you can proceed to ICS.

Thanks for all the help guys, successfully on the official rom now.
I did the following:
1. Flashed CPW rootable old gb rom using PC odin.
2. Rooted using zergrush
3. Flashed new ICS rom and chanfire kernel using mobile odin

Just did that exact same way myself - I always flash back to stock with PC Odin, and then re-root. Takes longer, but less hassles!

Help on getting back to stock GB from other ROM and kernel

Hey guys I want to go back to stock GB rom and stock kernel.
I am currently on Rocket v20 ROM and AbyssNOTE kernel.
The guide in the sticky only tells about how to go back to stock rom but nothing on getting back to stock kernel, I am confused as to if I will flash back to stock GB would it also change my kernel to stock or do I have to do it separately?

Once you flash a stock rom via Odin it already has the stock kernel for that rom in the installation script so just download the stock rom you want and flash via Odin
Make life easyer if you are wanting to root again choose a directly root able gb rom ie kk9

[Q] Help needed to install new roms

So last week, to save my near bricked device I used PC Odin to Flash a GB Rom. The device works fine now, with all root privileges. I ran titanium backup and installed all of my apps from the previous rom. But i can't seem to install a new rom using the recovery mode route. Whenever I try to install a new rom (GB, ICS OR JB) using recovery, I get boot loop or get stuck on the setup screen. Info on the rom I'm using right now -
Build Number- Gingerbread.XXKJ1
Baseband Version N7000XXLB2
Kernel Version- [email protected]#2
Android Version- 2.3.5
I want to install an JB AOSP rom. Please give me step by step instruction on how to do it.
First update the stock firmware to JB and then flash the compatible PhilZ kernel and try flashing. Flashing on ICS or JB is more secure and safe.

How do I update to JB?? I went to settings>>About Phone>>Software update>>Update. It says no update available.
Flash a stock JB ROM thru ODIN. Read dr.ketan's thread in original Android development forum and download an ICS/JB stock ROM from there or sammobile.com and flash using ODIN. Do NOT do any wipes on the GB stock kernel, may ruin the device.

the 2nd post has the GB roms.
Also visit sammobile.com for more ROMs, in case the ROM for your region isn't there.
