Hello, im new here and i have searched the forums and looked in google of how to revert to stock. If i understand correctly,having CM 7.1 i need to:
-Revert to EXT3?
-Download stock ROM?
-Use smartflash tool to instal stock ROM?
The reason i want to flash to stock is because CM camera video performance is getting worse and worse and i need it.
Yes. Those are the right steps to install stock rom.
thank you,i hope i dont brick my phone
The only person that can brick your phone is you. This is just a forum not a work place and we didn't sell bricks.

You can skip step 1. You don't need to revert to ext3 if you're going to smartflash, only if you're going to restore a backup or install a ROM via CWM.
I have made a backup from CwM before install CM7
Can i apply the backup again to the stock rom?
I did this but first I had to do backtoext3 (thanks for Paul obrien) and then flashed my backup. I'd obviously say do a backup of your current rom before you do anything!

I recently purchase a used unlocked rooted Nexus One and am trying to learn about all the N1 terminology and update processes. The below is my "About phone" info.
Android version: 2.2
Baseband version: 32.36.00.28U_4.06.00.12_7
Kernel version: 2.6.34-cyanogenmod, root(at)pershoot-ubuntu#56
Build number: Kang-o-rama 0.9b2 SP1 (FRF83)
Can you guys please tell me what all this means? I know it's Froyo FRF83 but:
Am I running stock recovery?
Am I running stock release?
What version of Cyanogen mod am I running?
I'd like to update to either FRF85B or FRF91 but I replaced the SD card that came with the phone and stupidly formatted it so I'm not sure if I still need anything from that card. I don't really need a backup since I haven't put too much on the phone since I got it. Thanks in advance for any assistance!
You are not running CM. you're runnning the kang o rama rom, which uses the CM kernel. You most likely do not have a stock recovery if you've got that rom on your phone. If you want to get back to stock, follow this:
http://forum.xda-developers.com/showthread.php?t=614850
Thanks for the reply! So if I go back to stock, I can flash to, say FRF85B, root and then install custom ROM?

Is your end goal to install custom roms? Because that is a very roundabout way fo doing it. By the sounds of it you can already install whatever rom you want. Including the stock rom made for unlocked phones.

I guess so. I haven't had a chance to look into which custom ROM is the best for this phone. It seems like a lot of instructions mention stock recovery/release. I just want to be able to follow along with the instructions If I can already do that, then I'll look into it! Thanks
Pretty much find a guide that tells you how to do it form start to finish. But skip past the unlock, root, and recovery steps. You probably only need to know how to use the custom recovery to flash new roms. Learn about nandroid backups, and how to flash, and you should be good.
Thanks for the advice guys! I just flashed to CM6. Seemed relatively painless. Hope I don't run into any issues!
Hello guys.
Before I go into it, let me start by saying I'm a complete noob at these things.
A couple of months ago (following guide on the net), I rooted my Optimus P990 and installed my first custom ROM.
Tonight I looked on the net to look at how to restore my device to stock.
I followed this guide.....
http://forum.xda-developers.com/showthread.php?t=1327599
It didn't work!!!!
Although the phone is still working, I have completely lost internet connection on network and wireless.
I'm worried about trying anything else in case I mess my phone up!!
Can anyone out there help me restore back to stock in noob dialogue??
Thanks in advance
Make a backup of everything.
Then go to recovery and wipe everything!
Perform a fresh install of your current rom + kernel combination.
Boot phone and everything should work now don't forget to restore your backups.
Thanks for the quick reply.
Will try it tomorrow.
Stupid question but what is the kernal?
Every rom comes with stock kernel, which is more or less a sort of 'driver' for your phone. Anyway, you don't really have to know what it is, only what you can do with it.
Custom kernels allow you to overclock your CPU frequency, this will make your phone faster and smoother. For example, stock kernel only allows your CPUto clock at the standard 1.0 Ghz, and custom kernels will let you overclock to 1.5 Ghz.
Custom kernels also allows you to Undervolt your phone. This means that you can turn down the voltages used at each CPU frequency. This will improve battery life. Custom kernels do much more things... But these two are the most important.
Look at my signature for the ETaNa Kernel, and read it for more information.
Ah ok thanks.
Is there a stock ROM that your aware of?
Sorry. When I say stock I mean revert my phone back to how it was when I first got it.

Have you tried restoring it using LG's PC Suite?
No not yet. I'm currently using a custom ROM. Cant remember which one it is.
Would an update via LG's PC Suite overwrite this firmware??
To reach your goal you must flash with nvflash technique, search in dev section thread about this. It will restore a stock phone, erasing recovery and root.
Lg PC suite won't be able to flash over a modified phone.
Ok. Thanks. What's the risk to my phone?
Sent from my Optimus 2X using XDA App
If you want to restore your phone to stock then head over to the MoDaCo site and look for a pinned topic in section on the LG O2X entitled "NVflash stock ROM release."
Following the instructions will restore the stock ROM from March 2011 to your phone.
Hi , some questions.Will appreciate if anyone could take the time and answer.
1. What things are left out in a nandroid backup? Are kernels included?
2. I can't restore a nandroid backup of froyo on GB without flashing a stock froyo build first, is that right?
3. Can I restore a Nandroid backup of GB 2.3.3 (say) while on GB 2.3.7 or any other 2.3.x? If yes, what if I am on different kernel than the backup kernel, can i still do it?
4. Suppose I am on 2.3.x based custom rom (say MIUI) and I restore a 2.3.x based CyanogenMod Nandroid backup, will I get my whole CM back or all my apps/settings of CM on MIUI?
Thanks a lot.

I'm not sure I can answer all your questions but I'll tell you what I've done.
From stock, after making a nandroid backup using CWM, I've flashed a CM7 having done all the usual wipe(cache,etc) procedures and gone back to stock using the backup. Everything is restored, including my settings, old messages, kernel, apps, everything. Be warned, you will obviously lose all the messages and call records that you received after you flashed the new ROM, unless you use an SMS/call log backup app. Same with CM7 to CM9 and back. So if you plan to flash a new ROM, the nandroid should be able to get you back to the exact same state that you were in when you made the backup.
I'm not much of an expert though, so I might be wrong. Feel free to improve on this answer!
1) Yes
2) Yes. Because of change of Linux kernel version.
3) Yes.
4) You will get whole CM back!

Thanks a lot guys...
One more question.
As you said, since I can't restore a backup of froyo on GB (because of linux kernel change), how can i restore a 2.3.x with a different kernel on a different 2.3.x with a custom kernel. Or is this kernel different from a linux kernel?
Asking because you answered the b part of 3rd question as yes (or maybe you didn't answer it at all, i am implying here)

Since GB to froyo is not allowed then CM9 (ICS) to CM7 (GB) should also be not allowed? Just want to clarify, have you restored CM7 backup on CM9?

Cm9 for the Ace still uses the old 2.6 linux kernel(same as the gb kernel) because linux kernel 3.x of ICS is difficult to port for our device!
I have restored a CM7 nandroid backup from CM9 and CM10 and it works perfectly!
Any Gb to gb rom restore works.

Cant restore my contacts,sms,apps and data from Gingerbread nandroid backup
Hi,
I have a similar problem.
Thought of posting a new thread but afraid that i would flood the forum.
I have taken NANDROID backup of my Gingerbread Stock ROM(rooted) using CWM.
Currently im in Cyanogenmod 7.2 for galaxy ace S5830.
I thought of restoring my Contacts,Sms,Apps using Advanced restore from Recovery mode.
Result: "MD5 mismatch" hence unsuccessful.
I tried restoring my Entire NANDROID back up.
Result: The Ace was stuck up with Samsung LOGO.
I flashed CM7.2 again after restoring factory settings.Things work but a blank phone.
So im in 7.2 again. How do i restore the GB Rom? I just want to safely export Sms,contacts and data using .APKs and retrieve back in CM7.2 ????
(BTW CM 7.2 gives me 2 days battery backup at 480 Mhz (underclock) with many useful apps customized as ROM. Quite Delighted. Thanks to Mclaw)
Custom and stock roms use different file systems. Custom uses ext4, stock uses rfs. You need to convert file systems before restoring backup.
Ways to do it:
-flashing stock firmware with odin.
-using the cf-root ext4 manager app, which you can extract from cf-root flashable zip.
Good luck
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.
Stock kernel is a gingerbread, one

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

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.

Hello,
This is my first post on Xda.
I followed the guides on here recently to Root my HTC Desire C, install Nameless v7 and Sim unlock the phone, which has worked. However I am finding the ROM abit laggy and I ham having problems with the WiFi and 3G data signal.
Is there a way of restoring the original HTC ROM?
I made a recovery file before rooting the phone, is it just a case of restoring this?
Thanks
Nameless rom is outdated. You should try cyanogenmod 10.
But if you still wanna go back to stock, restore that backup.
