Hello all,
I installed CM10.1 via this very useful post by verygreen. Now I have a need to revert to stock, for both the recovery and the ROM. Before installing CM10.1 I did make a CWM backup of stock using the bootable SD card created in that same thread. I have a couple of related questions:
When flashing that backup, will that flash stock recovery as well?
Do I need to boot with the SD card and use that version of CWM to restore the backup, or will any version of CWM work?
TIA!

It should restore it back to the exact state it was in when you made the backup. The recovery that you flashed when you set up CM should restore without an issue.

I have seen the same issue on other models forum but could not answer my problem.
Whenever I restore a Nandroid backup using either ROM manager or CWM recovery, all goes fine but on reboot I am stuck on the 2nd LG logo.
The only fix I found is to restore the ROM, pull the battery, boot into recovery, re-install CM7 from the SD card.
This happens will ALL the backups I made while on CM7.
I can however restore and boot the original LG ROM I backed-up after rooting my phone.
Am I doing something wrong?
Thanks.
LG Optimus 2x
CM7 nightly 39 (but had the same with previous versions)
ROM manager premium 4.3.1.3
CWM recovery 3.0.2.8
Try wiping all caches (including dalvik in advanced) and fix permissions. Also you can try CWM 3.2.0.x (you have to install it manually, Rom Manager does not let me download it)
If u restoring nandroid backup of cm7, flash cm7 rom after u completed restoring backup then u reboot.
1. Restore nandroid backup
2. Flash cm7 rom
3. Reboot
I did wipe all, but it did not help.
I am not sure about CWM 3.2.0.1. I will give it a try.

This is what I am doing, but why do I need to reflash CM7 after a nandroid restore?

I did a nandroid with my fr17, restored it and it wouldn't boot correctly, so i reflashed it without the wipe and it worked, maybe some system file wernt correctly backed up, hope this helps

It was a problem with the boot image not restoring properly (or at all perhaps), this should be fixed on CWM 3.2.0.1 (and possibly 3.2.0.0)
Thank you Rusty (and mikee2185).
Installed your 3.2.0.1 and it worked fine!
Cheers.

Great both of you rusty & pa64. I was facing the same problem with stock ROM restore with a certain version of CWM recovery. Rusty's 3.2.0.1 saved the day for me and restored successfully from the same backup which the other CWM version failed. Thanked both of you.
thanks temasek
it worked.
Hi, I have installed CWM and Cyanogenmod on my O2x, but I have lost the SD card containing the backup.
Can I revert to stock by putting an image on the new card and flashing with CWM or do I have to go another way?
Don't think there are any stock ROMs in .zip format, you're probably best using Smartflash to do it.
Will do, thank you
Hey, so I decided to root my Mini. That part worked (installed the zip from stock recovery) but then I attempted to install the CWM recovery using the update zip method and I don't know whether I should of used ODIN instead because I can't backup my current ROM.
If I tried flashing CWM recovery using ODIN , will it overwrite existing recovery and will it allow me to backup my current ROM. Can't mount system can't mount cache errors??
Just to verify also, I wipe user data before installing new custom ROM ? Been a while since i last installed one.
Thanks for your help!
Flashing CWM will overwrite current recovery, you'd have to flash stock to remove it
As for creating backups you can't backup stock roms because of how they work, the closest to stock that can be backed up (http://forum.xda-developers.com/showthread.php?t=1176927)
Hi,
I installed CM10.2 on my Nook HD+ but left the stock recovery on. I figured that it would help to reinstall the stock rom if something goes wrong.
Is there a way to install CM10.2 updates on my tablet without removing the stock recovery. The sdcard-based CWM worked on the stock rom but it no longer works on CM10.2. I have tried a couple of recoveries but none of them worked.
Do I have to install a custom recovery on EMMC to be able to do updates? If so, how can I install the custom recovery after installing 10.2?
Any help would be appreciated.

Just follow the "Make the CWM sd" guide from here .It works for the cm emmc install also.
Also why would you not flash custom recovery? If something goes wrong or if you want to go back to stock you could just flash the factory stock ROM from the cwm SD you made. You can get it from the same thread.

The same CWM SD you used to flash CM10.2 should still work with CM10.2 installed on emmc. You must have somehow modified the original SD. Try making the SD from scratch again. You can keep stock recovery on emmc if you want so that you can easily reset to stock if you want.
But once you have that SD working you can still flash the CWM or TWRP zip to emmc with it, along with the updated CM you wanted to install.

Hi
I followed e.mote's great guide on [NOOK HD/HD+] Installing CyanogenMod 10.1 for Dummies.
Everything worked great and I did a backup. The files below:
boot.img
cache.ext4.tar
cache.ext4.tar.a
data.ext4.tar
data.ext4.tar.a
nandroid.md5
recovery.img
system.ext4.tar
system.ext4.tar.a
How do I restore to the stock version with the backup?
Thanks
Just boot CWM and go to backup and restore and choose restore.

Leaplinlar, I accidentally installed the wrong ROM. I wanted to install to SD, but installed to the Nook itself. I didn't make a backup of the stock ROM, since I didn't plan to alter it. A factory restore brings me back to the CyanogenMod setup (which I don't recall ever seeing before). I assume I can use your stock cwm boot image, but I actually need to find out where to get the stock rom to begin with. Any thoughts?

I have it in my HD/HD+ CWM thread linked in my signature. See item 6 and get a Plain stock ROM.
