If i clean flash a new Rom but restore the data part from a backup i did earlier from another rom from recovery will it work? Im using TWRP recovery.
ive always had mixed results on this. if youre going from a TW ROM to an AOSP or AOKP rom, likely not. If you use TiB and backup your apps and their respective data, and restore them via the same method, that 99.9999% of the time works

So when i move to a new version of a rom, how do i keep all my info? I was just used to backup/restore with a rom version change on cyanogenmod where i can restore and it won't overwrite the previous rom and revert changes.
Do i always have to wipe all data when uploading a new rom?
Shouldn't the nandroid backup restore everything but keep the current rom?

I learned this today myself.
General rule is:
Switching ROMs? Wipe everything
Updating a ROM? Wipe cache and dalvik-cache
Installing an addon? Don't need to wipe anything
i guess that answers part of my question. the main part was when i switch roms, how do i keep all of my info? when using cyanogenmod, i could back up using nandroid backup from recovery, and restore when i installed a new rom, however it seems with some roms i cannot do this as it will overwrite changes in the new rom. how do i avoid this, how do i keep all of my data while not overwriting the new rom changes?
I'll try to answer your question, if I think I know what you mean by data. Data from ROM or data from phone/apps.
If data from phone/apps. then I would suggest Titanium Backup(Paid version) from market. Once you install a New ROM with a complete Data wipe, what ever you backed up with TB from your previous setting can be restored. This is good if you are installing a ROM not from the same dev.
Other wise if you installing a ROM from same dev, a revision, you don't have to do a wipe data.
If data from ROM, well I don't know there, never had to do it.

ok, so you're saying when, let's say, going from 1.0 to 1.1 of the same dev rom, just an update, i do not need to wipe data?
Yes. The only time you ever need to wipe data and cache is when you trying a ROM from a different dev.
If installing a different rom, then that's where TB comes in handy.
Side note: Also CWM ROM Manager backup utility will backup every thing if you wanted to revert back.
Dayton advice above is a good rule to follow.
There's other bits and pieces but search or ask.

hey guys, i want to ask about backing up phone.
i have stock rom back-ed up in clockworkmod, however now i have installed Miui.
if i backup phone again, will it erase the stock rom backup?
or will it just pop up another date to let me restore either miui or stockrom?
It'll have a different file-name (Time + Date), so it will be saved alongside any other backup you might have.
thx for the info bro.
Finally was able to succesfully root my phone last night, and now I am wondering how to actually flash a custom ROM. I figured I'd start with Cyanogen since its the most popular and seems like a good starting point. So, I have a few questions.
1. How do I install the custom ROM? (Cyanogen in this case) Also, is this process the same regardless of what android version I have? (I'm currently on the stock 4.1.1 OTA)
2. Should I install a custom kernel? If so, is it the same process? Also, is my data wiped just the same as with flashing a custom ROM?
3. If I make a backup with Titanium Backup, will I simply be able to access/redownload my app data it if I redownload Titanium after I flash the ROM?
Any and all help is appreciated!

I'm sure everyone has their own advice, but I would say first thing you'll need is ROM Manager
Download the ROM you want and place it on your sdcard. Use Titanium Backup to backup your applications, and then restart your phone in Recovery Mode. When in recovery mode, make a backup by going to "Backup and Restore" > backup. Then do a factory reset and wipe your cache. Install the new rom and enjoy the addiction
Also...be careful making sure that any kernel flashed is compatible with the ROM you are flashing. If not you can brick your phone.

I'm considering trying out a different ROM on my T-Mobile Galaxy S2. I've done quite a bit of modifications to my stock 4.1 ROM.
I made a complete backup of my phone using TWRP recovery (both system & data backed up).
Now, if i decide that after trying someother ROMS, i decide to revert back to the stock ROM i was using, can i just restore my backup with TWRP Recovery and all my settings, apps, screens, etc. everying will be restored just like it was before i put another ROM on?
I've been very hesitant to try this for fear of needing to reconfigure everything again.
I assume everythig restores as original but i need confirmation.
Thanks.

Yes, it does....if you do a full backup...
And by the way, questions belong in the Q and A section....cheers!
Hi,
I'm running CM 10.2, and using TWRP 2.7.1.2 Recovery.
I think that when I was "cleaning" my phone prior to installing ROMs, I was a little too thorough, since based upon my poor 3G/4G performance/coverage, I guess that my PRL list is pretty minimal.
I gather that the procedure to fix this is roughly:
Make a Nandroid backup from Recovery
install a stock ROM
update to latest PRL
Restore the Nandroid backup
But I don't understand some of the fine details. In particular:
When preparing the Nandroid backup, what options does one use?
What sort of "wipe" if any, does one perform at this point prior to installing the stock ROM
HOW does one install the stock ROM image asanti_c_sprint-user-4.1.2-9.8.2Q-122_XT897_FFW-5-6-release-keys-cid9.xml.zip ?! It looks a little different than custom ROMs
After updating the PRL, what sort of "wipe" should I perform prior to recovering from my Nandroid backup? I'd like to be thorough, but not so thorough that I wipe out the PRL update. Where does that PRL list reside?
Does the Nandroid backup include the ROM images which I flashed? (CM 10.2 and the corresponding GAPPS) If not, then in what order does one flash ROM images and recover my Nandroid backup?
TIA ...
1. Doesn't matter, whatever you feel you need to restore. At a minimum backup system. Backup data if you want your data saved...
2. None, if you use RSD Lite to reinstall stock it will wipe ALL. Everything will be back to stock (including recovery).
3. RSD Lite.
4. PRL List should not be wipe-able from recovery, AFAIK. Factory reset should be fine.
5. The backup will include whatever was currently running on your phone - CM, gapps, any installed applications, etc. Simply restore your backup, no order of operations here. Of course you'll need to reflash TWRP in order to restore your backup (again, flashing with RSD Lite resets the ENTIRE phone, including custom recovery).
If you had taken a backup of the stock setup, you could skip the whole RSD Lite crap and just restore your stock setup, download the PRL, and restore your CM setup. For future reference, step #1 after getting custom recovery is always always ALWAYS take a backup of your working stock setup before making any other changes.
Thanks for your detailed response. As a Mac user, I believe that RSD Lite isn't a viable option for me. I do have another Motorola Photon Q phone with the stock ICS image, but don't know whether that is helpful in this case.
I guess that I need a strategy using adb, fastboot and TWRP. Thanks ...

The stock backup from that other Q would work. Just do a factory wipe and restore 'system' only from that other Q.
