Nandroid blobs and different Roms - Android Q&A, Help & Troubleshooting

With the way that nandroid backups use "blobs", can we backup Rom A, install Rom B, backup Rom B, then restore back to Rom A if needed?

[Q] Installing new ROM and keeping old files

I know about Titanium, just to start with.
My question is about backup files using CWM, if I install a new rom and restore my system/cache/data will the phone work normally after that?
My main goal is to keep my installed apps as they are on the new ROM, so i guess data is the only thing i need to backup by right?
Thanks in advance!
Backup system + data using titanium backup.
Also backup current rom using cwm incase anything goes wrong while flashing new rom.
After u instal new rom instal titanium backup and restore.

Switching ROMs

Just wondering......
I'm on simply honey 5.1 and have been updating with it's no wipe script. I'm curious in trying MIUI and Cm7. I just wanna know if I could restore with a cwm backup, and get ask my apps back without having to do a titanium backup.
thanks!

I believe you can but you if you go to CM7 or MIUI, you will have to odin back to stock if you want to revert to anything else. But from there you won't be able to just restore your CWM backup because CWM does not backup the kernel. Best thing to do then is to flash any GB rom to get back to GB kernel. Then you can restore your CWM backup.
Anyone correct me if this is not the case.
But wool all of my market apps still be installed thru the cwm restore? Even if the ROM I switch to wipes?

Yeah the CWM backup backs up your current config exactly as it is (*except the kernel). So if you end up restoring, it should be right back to the way it was when you backed up.

Question about nandroid backups

I did a nandroid backup on stock GB. If I flash an ICS rom and do not like it, can I restore the GB backup or do I first have to flash a GB ROM? If yes, does it have to be the same stock version I did the backup on?

Do a full wipe\format and then restore the GB backup. You should be fine.

I believe AppExtractor can extract a bunch of stuff from a NAND backup.
Thanks it's a nice app, but it let's my restore everything but apart from my data and apps
