[Q] Nandroid backup - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
Ive tried to search for a thread about this subject but couldn't find it, so my question is;
I'm using MIUI ROM right now, And i want to go back to STOCK Gingerbread with Siyah kernel that i had.
I luckily had made a Nandroid backup before I flashed MIUI ROM.
Do i need to flash STOCK first and after that restore with Nandroid backup ?
Or can i Restore the Nandroid backup right away via CWM ?
The reason I'm asking this is because i've read things about that MIUI uses a different partition-structure ?
Could anyone help me with this please ?

You can restore your nandroid without flashing anything

Does nandroid backup include modem and kernel as well? If I restore using nandroid backup, will it restore the modem and kernel that I had before in addition to the rom?

Yes, it does. Nandroid backups pretty much backs up everything your phone was at that state.

Baseband and nandroid restore/backup

Hello, i used the search button and didnt find and answer so i apologize if this topic has been already discussed.
I test all the roms available on this forum and make regular backups using streakmod recovery and nandroid and it saves huge amount of time.
I have noted that everything gets restored except the baseband and this is normal behaviour as I ve read in a post by the great TheManii that nandroid backups dont change the baseband
but but my question is is it advisable to fastboot flash the correct baseband to align it with its oem version after a nandroid restore or not?
details:
i restored back from gingerstreak beta2 to a previous backup of streakdroid 1.9.1 with BB 354.
now i get:
oem version shows
GAUSB1A135411
BB shows
GAUSB1A140314-US
should i fastboot flash amss.mbn of the 354 only? or both the amss.mbn and dsp1.mbn?
many thanks
The best way to make sure everything is in sync is to flash the complete stock ROM with the baseband matching your backup first.
If you want to restore a nandroid of a stock rom and you have been using something else flash the stock rom that matches that backup and then restore the backup.
The same goes for custom roms, flash the stock rom the custom rom was based on first, then the nandroid of the custom rom (or the custom rom itself if a first install).
Thankyou for yr advice

how do you backup baseband
I have been looking around to find the answer to how to backup the baseband. From what I understand Nandroid does not backup baseband. So how would you backup baseband from a fresh dell streak?

Yes, your understanding is correct, nandroid doesnt backup baseband. i have followed marvin02 advice and reflashed stock rom 354 (matching the custom rom version sd 1.9.1 was built with 354) then fastboot streakdroid recovery then did a nandroid restore.
there are available all the baseband files for each rom so another way (not really the advisable way) is to fastboot flash just the baseband risking an improper alignment of the files.
if you want to backup only the baseband just go to the dell streak page in xda and download the amss.mbn file

Nandroid backup after flashing a new ROM?

Is it recommended to create a new Nandroid backup after flashing a ROM and setting up the phone again?

Yes, that way if something is wrong with the rom or you don't like something when you flash it you can easily revert back. Grab Con's Flashable recovery helper, http://forum.xda-developers.com/showthread.php?t=1547496 . Make a backup, and when you want to restore it flash the recovery helper first. It will take you to bootloader with a newly created ph98img, let it update and reboot . Now, you will be in recovery again . Just select backup/restore..select restore and then the nandroid you just made . This time it will restore the nandroid including the kernel.
Otherwise, when you restore a nandroid you still have to remember to flash the same kernel that was in the nandroid because with S-On our backups can't restore the kernel.
P.S. just remember to remove the PH98IMG zip from the SD card afterwards or you will have trouble booting back into recovery if you don't.
If on the .22 firmware, dont backup android secure. Also if restoring an ICS nandroid while currently on ICS no need to flash a kernel.

Restoring CWM 6.0+ backups

I know that cwm versions 6.0+ have a new method of backing up files. After restoring an older GB rom that has an older version of cwm, I can no longer restore these new cwm backups. I'm not aware of a cwm 6.0+ existing for GB. I tried installing siyah's GB kernel, but it only had cwm 5.5. Does a cwm version 6.0+ exist for GB roms?
Our kernels come with cwm built into them. And since gingerbread kernels aren't being developed anymore I'd say no. Good luck, happy flashing.

I may be wrong, but as far as I am aware, CWM6 is only for JellyBean Builds. As Phalanx said, there is no V6 for GB.

CWM 6 is available on ICS. But i didn't think it existed for GB. Oh well, guess i'll have to start over.
To restore em just flash CM9 or 10 first and there ya go. CWM 6 is ready to restore your backups.

Well I feel stupid..I'm not sure why I didn't think of that. I'm about to just reinstall shostock2 and then voila, cwm 6. Thank you sir!
Also, if you try to restore a cwm 6.0 backup from an earlier version of cwm, it will restore only the boot.bin, and fail on the rest of the backup. However, the phone will now have the cwm 6.0 kernel, and the next time you restore, it will work.
Here is what I do when I am wanting to restore back/forward from CWM5 saved nandroid to/from CWM6 saved nandroid.
RESTORING A CWM5 NANDROID:
1. If I am on CM Version with CWM6 and want to go back to a nandroid backup made while on CWM5 I flash this CWM5 based siyah kernel http://db.tt/owgZanij
2.Once I have installed the CWM5 Kernel I hold down volume+/- and power to restart recovery.
3. I choose the nandroid backup CWM5 based and restore it.
RESTORING A CWM6 NANDROID of Cyanogenmod firmware:
1. I flash this Siyah CWM6 Kernel http://db.tt/iHax4mvQ
2. Once I have installed the CWM6 Kernel I hold the Volume +/- and Power button until I am rebooted to recovery again
3.I choose the CWM6 (CM10 in my case) NANDROID BACKUP and restore
As long as I am on the correct version of CWM my nandroid backup will work properly. Even if the nandroid backup has a different kernel than the siyah kernel you just flashed. The nandroid restore will overwrite the kernel back to the correct kernel from the rom you were originally on.
I also use this method of flashing these kernels if I want to install a new rom based on Sammy builds or based on ASOP/CYANOGENMOD ROMs. So depending on which way I am flashing I prepare for it without having to flash a complete rom. Since flashing a kernel is much quicker. Just need to remember which way you are going and which kernel I want to get it done.

[Q] Nandroid Restore issues with Sammy JB

Hi Everyone,
Every time I restore a sammy JB install from recovery it always hangs on the bootscreen and never boots up. I was wondering if anyone has had this issue before or its something that I'm doing wrong
When restoring I always run an odin flash using mobile odin and root it with philz. I then delete all the system folders, wipe cache etc and restore.
If i used a different kernel to backup the install i will install that kernel before restoring.
I've tried several roms such as neatrom, Alliance and Wanam but get the same result. CM/AOSP roms restore ok.
If anyone has any suggestions it would be much appreciated.
Many thanks
Question since you state you using philz kernel why dont you use his CWM to backup and restore your backups instead of Odin mobile.
iT comes as part of the kernel http://forum.xda-developers.com/showthread.php?t=1877270

Thanks for your reply.
I only use mobile odin to flash official firmware so its a fresh start before installing a rom.
I've tried to restore from philz before but had the same problem. Normally use Dorimanx.
I myself had no probles with Mobile odin pro of CWM in Philz kernals and since Philz kernal this tends to be the normal backup or flashing aid for me. Since I have a Micro SD card install back up and roms are place on this..
by the way Im using SuperSUPro and not Superuser for root.

I have a possible solution just flash entire original rom(the one you are going to restore) once, then restore your nandroid backup, clear cache/dalvik, reboot. I have a hunch on the problem that it might be caused by another roms /preload partition data (our nandroid backup won't usually backup it by default so it actually never gets wiped or overwritten)
Edit :I forgot to mention a factory reset at the beginning.
