[Q] Restore sdext from nandroid?

Hi,
From one ROM i do a nandroid backup and install a new fresh ROM..
And all my apps are on sdext in my old ROM.
So can i restore my apps directly reflashing sdext.img taken from nandroid backup to my new ROM???

Use Advanced Restore in Clockworkmod, which has the ability to restore a single partition of your choice.
Alternately, use fastboot. (fastboot flash sd-ext sdext.img), but I am not very sure whether it is capable of sending a huge img file over fastboot, Google doesn't seem to help either, but, in any case, trying it out shouldn't be harmful.
However, I can't say for sure whether your purpose will be fulfilled by the process you are following or not.

thanks 3xeno for the suggestion...
currently using CM7 wit CustomMTD... i ll try it wen i get a new sense ROM...

I found a new app today called app extractor, it allows you to extract single apps+data from a nandroid backup.

[Q] Nandroid backup and boot image restore

Hey,
If you do a nandroid backup, then wipe, flash a new rom and a new boot.img, will the boot.img from the previous rom be restored if you do restore it? Or do you have to fastboot flash it again? If so, is the boot.img which is found in the backup folder the one to use?
Thanks

yeah i am wondering the same question. Actually I have a nandroid backup of the stock rom, and i flashed other roms before too. I tried nandroid restore and everything did go back to stock, but I am concerned whether I need to flash any boot.img? if the stock kernel is untouched while flashing other roms, does that mean i dont need to reflash the boot.img?

When flashing other roms the stock kernel is not changed. Unless you have an s-off device. If you did not fastboot flash boot boot.img then when you restore your back up you will be fine. If you did flash a new kernel then you will need to flash the boot.img for your backup as the backup will only restore the kernel on s-off devices.

Clockwork recovery - can i restore without kernels?

Hi guys, i have a backup of my stock rom (The software that it comes with outoff the box) and im currently using charmander rom which ive flashed a kernel for, so if i flashed another rom, say for example cynagenmod9, could i restore back to charmander? Even if i flashed another rom after it with a different kernel? Or am i getting confused? Thanks.

When you restore a backup in ClockworkMod, it doesn't restore the boot.img (which contains the kernel).
So whenever you restore, you must also re-flash a boot.img that matches the ROM in your backup.
For example, if you install CM9, you could get back to charmander like this:
1. Connect the phone to your PC and reboot it into bootloader
2. Use fastboot to flash the charmander boot.img file
3. In the bootloader go to hboot then select recovery
4. Restore your charmander backup

Ahhh okay, thank you

backup question

i just wanted to know since a nandroid backup backs up the boot.img of a rom as well as the data, could i make different "stock" backups of roms and just format the system and factory reset and restore roms from backups? like say i back up pacman rom, then go to stock. can i just reflash pacman without the boot.img (say i dont have a computer) and restore the backup? would that make the boot.img work? cause if so i could have one backup of each rom on my 16gb sd card and just reflash when i need it. thanks guys

Which recovery are you on and are you primoc or primou?..... I don't think the recovery will actually backup the boot.img even though it says it does... someone else might be able to answer better though

Sorry forgot that but I'm primoc with twrp 2 recovery on Pac man 19.3

(Guide) return back to stock rom after cm 10 or aosp rom

Yesterday I wanted to go back to stock 4.2.2 Rom on my HOX, I restored my nadroid backup but it didn't worked.
I surfed on internet looking for a solution but every post said you have to re lock bootloader then run ruu blah blah blah....
Solution- if you have flashable zip file of stock rom ( I downloaded it from android revolution hd website )
1- unzip the file copy boot.img in c drive of your computer.
2- flash the zip file via cwm recovery.
3- turn HOX power down return back to fastboot mode plug usb in it.
4-( I assume you have proper setup of adb if you don't have then ask google) now run this command in adb "fastboot flash boot c:\boot.img
5- now reboot your phone let it start upto the welcome screen.
6- turn it off go back to cwm recovery now you can restore your nandroid backup.

Why posting this in this context ? It's confusing. You do not need a flashable zip of a stock rom. A custom recovery and a nandroid backup is enough ! And it's all the same coming from any rom.
1: flash the boot.img from the backup
2: perform a full wipe in the recovery
3: restore the desired nandroid backup
4: reboot and enjoy
No other way, it works always like that ! And there are many good guides already.
So i think you did something wrong between full wiping and restoring the nandroid

Flash boot.img after the nandroid backup is completed its confusing because you are advanced user.

No your part of flashing a stock rom first is confusing and absolutely unnecessary ! Why would you flash a rom before you want to go to stock ? It's all extra you have to do !
Just do as i said and it works, and again ... this can be found on whole xda. It's not that you found some missing key here.
And where did i say anything about flashing a boot.img after restoring the nandroid backup here ? And as additional info, a boot.img can be flashed before or afte. It makes no differrence
And between your #1 and #2 you need to full wipe. If you flash another rom straight over an aosp (or any other rom) it will result in a non booting phone ! So your info contains not only unnecessary steps, it's also incomplete
