[Q] Backup stock ROM before installing CM7.x - LG Optimus 2x

Hi all. Due apologies in advance if I sound like a total newbie.
I'm looking to install CM 7.x on my O2X. Before that, I want to backup my stock LG ROM so that I can restore it in the event I need to send the device back to the service centre for any reason. Would appreciate any help or pointers for backing up and restoring the stock ROM on my handset.

To have a perfect restore you'll have to get rid of CWM either, that means restoring original recovery partition. The only way to do this is to flash an original complete ROM with nvflash.
There is a thread about this with all original Froyo roms, should be easy to find in dev section.
After backup LG update tool will get you to the latest version and it will be ok to go back for repair...

i think you don't need to backup stock rom, you only backup your data and system data with titanium backup. because there is tool like nvflash that's already mention or smartflash tool to flash your phone to the original stock rom

Yes I supposed he knows that I assumed he wanted to know how to restore a complete stock ROM including the stock recovery to preserve warranty if he needs to get the phone back for repair.

you can find NVFlash & Guide in my folder :

How can i backup my Rom along with everything in it ?

Hi.
so i want to back up my rom and try a new one. because so much stuff installed and tweeks i have already made i dont want to lose them all.
what is the possible way to backup everything. and then try a different rom, if i didnt like it i can go back to this rom like nothing happened ?
titanum backup only backup your applications as far as i know. not the whole rom with application
Rom Manager... i tried to do backup once before but it failed to find the rom when i went to the recovery. i dont know if i did something wrong back then. but any help would be thankful
Do a nandroid backup through recovery
Use ClockworkMod and do a Nandroid. Make sure it's the latest version, as one of the CWM versions wouldn't restore properly without reflashing the ROM over the top. Latest version works really well though.

NANDroid backup

what is a nandroid? how do you perform a NANDroid backup of your current ROM? im going to cm7 stable from kj1. just wondering cause it says in the steps to install cm7. thanks..sorry for the noob ques..
its making a complete backup of ur current rom settings,apps and all. with i897 gingerbread roms i dont think u can restore a nandroid backup. but u would normally do a backup in recovery with cwm.
yes, nandroid on i897 ginger roms do not work.
but the procedure would be to make a backup. then if you flash a different rom from what the backup was made from you would have to flash the rom back that was backed up THEN restore the nandroid and it will be like you never flashed away from that rom.
DO NOT EVER restore a nandroid to a set up it was not backed up on, it will bootloop.

can you expound on that please...hahaha..sorry im reading it over and over..just need to clarify..what you mean? thanks btw guys for the reply..so basically nandroid backs up your rom..cause just the name sounded confusing..i mean why name it nandroid when they can just say in the intructions before flashing a rom to just "back up" your rom..haha..i thought nandroid was something else..cause i heard other people saying something about efs or whatever and backing it up but i dont even know what that is especially..thanks though for replies..got it..
Say you back up your current ROM, then flash another. You can't just restore ROM A onto ROM b. You have to flash back to ROM A and THEN restore the nandroid and it will be like you never flashed ROM b. All of you settings and everything will be intact.
Efs is totally different, that is a partition that contains your phones individual data, it's imei which you have to manually backup it's not included in a nandroid.
Components backed up by NANDroid
Which of these components does NANDROID back up?
- bootloaders?
- kernel?
- system apps and other apps?
- modems?
- other parts of the OS?
Thanks for sharing the knowledge.
The firmware and system settings.
No kernel
No bootloader
No modem

Kindly clarify this please, i want to backup my stock rom before going custom.
So inorder to do a complete backup, we need to do a nandroid backup and also backup imei separately?? and then restore both of them when i flash back to stock??

They are two separate issues, really, but you are correct that you should back up both.
Nandroid lets you go back to a previous state, as long as you flash back to the correct ROM before you restore it. It will not let you restore data to your new installation, though. If you want to restore your applications in your new ROM, you can download Titanium Backup from the market which will let you batch save your applications now and restore them on your new ROM (It can also save and restore system data, but don't restore system data between ROMs, it causes all sorts of weird issues).
Backing up your EFS folder is something you should do, but hopefully will never have to restore. Your EFS folder contains information about your phone and should never actually get touched in any way when flashing ROMs. However, things go wrong and sometimes this folder ends up getting corrupted for whatever reason, which can lead to a corrupt IMEI code and no service. If this were to happen, you would restore you EFS from backup. I think it's safe to say most of us have never had to actually do this, but better safe than sorry. You can do a search for backing it up and find several threads about it.
Happy flashing!
lol...I was about to do nandroid backup! These post wre real helpful...thank you!
See this thread in the Development Forum for Corn Kernel... It has a working nandroid. BTW, that kernel is for i897 Gingerbread Roms.

When I run a nandroid backup I see it processing these:
- boot image
- recovery image
- system
- data
- datadata
- .android_secure
- cache
- sd-ext
Can anyone explain some of these terms to me? I am pretty new to all this.
This thread has all the goodies defined pretty well http://forum.xda-developers.com/showthread.php?t=1093062

You will need to first get it on the same modded ROM and then flash the backup. They will then be identicle
Hello,
This is the thread I was looking for. It just tackles top backup/restore issues I want to be positive of before tinkering around.
Now, what app is capable of doing a nandroid backup, if any? RomManager?
If a nandroid backup consists of the firmware and system settings but no kernel, bootloader or modem, how are these three backed up then?
My goal is making a stock unrooted (if possible) backup.
A concerning restoring, from this thread I understand that the restore process is composed of:
1st restore ROM A (which?)
2nd restore nandroid (which?)
3rd restore data/apps (Titanium is able to)
4th restore EFS folder (how?)
Please, correct/suggest. I appreciate.
Greetings,

First of all, you have revived an old thread with now false information. A nandroid does include modem and kernel. Bootloaders can't be backed up, and there really wouldn't be a point in that. No app can do a backup, and please don't use ROM manager; it's obsolete. As for your steps: You probably only need to flash a ROM first if the partition table is being changed. Meaning you can't restore a Samsung ROM over an AOSP ROM. You won't need to use titanium backup because you will have restored the phone to the exact state it was when you took the backup. Meaning there won't be anything to restore. Efs? Don't touch it, we never will be deleting it.

Modems and kernels ARE NOT backed up in a Nandroid...
Hello,
@korockinout13: I don't think I'm providing false info. Actually, i've been gathering from the thread. I think there's some disagreement on what a nandroid backup really backs up from the views expressed in the thread. Plus, it's pure netiquette not opening new threads for a topic already started somewhere else in a forum. It's power ecology. No hard feelings, though.
Thank you and b-eock for your replies. I think I'd rather use cwm instead.
My goal is still the same: making a stock unrooted (if possible) backup as there are no roms available for my brand new Mini:
pda S5570XWKQG
phone S5570XWKQ5
csc S5570YOGKQ3
android version 2.3.4
Kernel 2.6.35
Thank you both!

Someone told me about the modem part, so I'm not really sure about that. But if it doesn't backup the kernel, why does restoring a nandroid put you back on the kernel you had previously (i.e. Glitch)?

[Q] How to get back to Stock Rom from ICS!

Hey Guys,
I have a rooted LG p990 from FIDO in Canada. I was wondering if i can get back to stock rom in order to get the ics OTA update.
I have NOVA HD REBUILD 1.1.0 (unofficial cyanogenmod 9) on it currently with the 2.6.32.59-HP-CM9-ICS-SUPERSONIC-RC2 Kernel.
I also have a nandroid backup of GB, but dont want to backup because i read online that the kernels are different and something to do
with the file system so you can brick your phone. Can i just restore the nandroid? or go back to stock? and how?
New to flashing, ROMS, Kernels etc. so i need help
You can restore the Nandroid without any problem. Everytime you change the ROM, Kernel will also be changed along with that. So after you restore the nandroid backup, your kernel will also be changed to Stock Kernel along with ROM. There wont be any problems.
Press THANKS if my answer is helpful.
If you are in Canada then I don't see how you will get ICS ota when LG Canada have said they won't release it there.
I doubt any release of ICS will be ota.
You'll possibly need to flash a downloaded rom to ICS anyway. Not sure if just changing regional settings will work but someone else can chime in on that one.

Are you sure, because i read online that ics changes the file system rendering the nandroid backup useless. And finally I don't need to flash a gingerbread kernel before right?, as nandroid restores my stock kernel.

Yes... The nandroid restore will restore the stock kernel as well. I have tried a few ICS Custom ROMs and restored my Nandroid backup and it restored the stock kernel.
One more question
Will the nandroid backup also restore the stock baseband and RIL?
Help - boot loop
I did the restore and it restored successfully, but when i reboot im in a boot loop and cant get past the white lg logo! HELP
FIXED
Changed to ext3 file system and it works now

Yes. Download a stock image from xda threads and flash it. You might have flash a new kernel if your coming from ics.

[Q] Need to backup the stock rom v16

Hi all I am from India and I got this Mi3 phone a while back in august. Now i have never updated the phone and its in version MIUI-KXDMIBE16.0.
i am very satisfied with it and I have never wanted to update as of now. battery life is great. Not i've seen that the newer update provides more ram space and so on. I want to update to the new version. But problem is that If i dont like it I want to comeback to this (v16) version. i have looked online and no one seems to have the stock rom of the mi3 v16. If I update it means I can never come back to this rom only version 15 or version 18 is available on net.
So here are my questions
1. can i make a stock backup from my existing phone? If yes how? (I need to upload a copy to the forum also seen a couple of people asking for it)
2. if stock is not possible can i use any other recovery to backup this current rom and revert back to it? if yes how?
Use cwm recovery to backup and restore a nandroid backup.
stock?

[Q] How should I backup the original firmware before flashing to CM?

Hey guys,
before I'd flash my Xperia SP with Cyanogenmod, I was wondering what way I could backup (And restore!) the original firmware of my device incase I want to switch back to stock.
I just want to be sure I don't mess up and I can repair back to original

I don't know how you'd back up your firmware, but there a list of all stock FTF files here. Just find the appropriate one, download it and flash using flashtool when you want to go back to stock. Note that this will factory reset your phone and you'll lose all your data if you didn't have a backup
You can also make a nandroid backup if you have recovery installed.
Also to back up your apps, I suggest an app like Titanium Backup

After you install recovery, there is an option called back up and restore. Hit that and backup your stock rom to sdcard.
