I want to clear my phone completely back to bare-bones 2.1. I do want to save my last good set up with froyo, so;
1) Is it a good idea to do a complete restore.
2) Is it better to leave the phone as is (leaving b/u in tact) or can I save the last b/u to my computer? If so how (Tibu, ROM Man???). How would I return this file back to the phone if necessary?
I never do any more backing up than Titanium Backup of apps. I know clockwork recovery can make a nandroid backup. It saves it to a folder on the internal sd card (Clockworkmod I think) and you could copy that to your computer. Then copy it back if you want to restore. The feature is there, I assume it works, but I have never personally done it. You could do all this through clockwork recovery, make the back up, and restore later if you want. You can leave the backup on your phone after you go back to stock, odin will not clear it off unless you do a "Master Clear". Then you would just have to reflash clockwork recovery, and you could restore.
I've transferred both tibu and nandroid (rom manager) backups to my pc and then restored from them after a master clear by copying them back to the phone from the pc. With the nandroid backup, you have to reinstall the rom first, and it must be the same rom you backed up.

I was thinking this was the case. My only concern is on the re-install, would I be correct in my asumption, that not only would I need the rom installed but the theme as well?

Disclaimer: I've not tried it. A nandroid backup restores everything in the rom plus apps, but not the kernel, so it should restore your theme and your apps. In that case you may not even need the tibu.

Well it's done, we'll see how it goes when I need it
I think the trick is having a working base rom and it being the same as the backup. Id be curious to try restoring a previous version of the same rom. How bad could it get?

That may not be a simple question to answer with any certainty. I would not even consider attempting it unless both phone models are exactly the same, you didn't say for sure that this is what you were meaning. If the models are the same: insure they have the same bootloader and modem installed. Then I still would not do it unless the ROM on the second phone is comparable to the ROM you are moving to it. The reason for this caution is that partitioning schemes are not the same on all ROMs, it can even change in a newer version of the same ROM.

This :good:
So I installed a custom ROM and I love it. But I want to go back to stock for right now. I have safestrap installed, but I apparently lost my backup. Can I turn it off and go back to the stock? Or do I need to actually reset my entire phone?
Also, can I save my game data and use it for my stock rom? I don't wana lose my progress in bubble blast 2.... any help would be appreciated.
Just back up the files you want to use on stock. Go into recovery and toggle back to non-safe mode, assuming you flashed the custom ROM on the safe partition.

Use titanium backup to back up any apps/games and their data and then switch back to nonsafe and you'll be at stock. Download titanium backup again and restore your apps. You can also use my backup root to transfer your call logs and sms/mms. Just don't try to restore any system apps or settings with either of the aforementioned apps as it may cause issues. If you have any doubts about what you can and can't restore, make a safestrap backup after switching to nonsafe mode, then if you bork anything you can restore and try again
Note:the free version of those apps should be sufficient for what you need

Thank you both. Wish I would have read the titanium backup before I toggled it off. So now that I'm feeling optimistic, I'm toggling it back on, doing the titanium back up and then back off. I was a little nervous about this, but now I'm just plain old curious.
So long as you make safestrap backups before doing anything you aren't sure about, you should be fine. Its pretty hard to screw up your device so bad that you can't do a safestrap restore with a lesson learned. I've had to do tons of them.
It can also be a good idea to trying restoring your backup right after making it to make sure its good if you're gonna be messing around alot. I've had a md5sum mismatch screw me over before

i have been lurking these forums for a while. but made an account for this. i have been flashing roms and what not for about 6 months. as i was fed up with waiting for updates. anyway straight to the question.
my IMEI has changed recently to the 004999010640000 generic one. does that mean is corrupted. what are the risks/problems that i will face if i leave it or try to restore? should i re flash stock and work my way back to custom roms again? or are there other methods that i can do? do these methods restore the original IMEI or a new one. is there a problem with that?
its been like that for about 2 months. i have no backups. it also makes my phone show up twice on marketplace on a desktop. i guess google can see the difference.
i found my old imei . fair sure i shouldn't tell you what it is. is there a way to change it back to that code? without to much hassle? i really dont want to flash back to froyo and start again. i would settle with a factory wipe and some instructions on preventing this from happening again
Please follow instructions at own risk. I am fairly new to all of this but below is what work for me.
If you have a backup, which I did, then you should have an efs folder inside your backup folder. This contains the files you need. (nv_data.bin.md5 & nv_data.bin)
The easiest is to place these to files in the root folder of your internal sd card. Then with something like Root Explorer copy these files & then go to the actual efs folder of your phone and paste them of the existing files in this folder.
Once you have done this delete the nv_data.bak.md5, nv_data.bak and nv_log files.
If you don't have a backup others have said the best is to flash a stock rom which should then restore your original IMEI number. I have not personally done this but it is mentioned a lot.
I don't know how to change the IMEI number any other way.
i was hoping there was an easyer way. i dont have a baack up but i guess i will have to make one when i get it back. ill try it when i get some free time. would any stock rom work or do i have to get a build thats froyo or ginger. would this idea work?
first make back up of files i need. and do a titanium backup and nand
second flash back to stock. check for restored imei
3rd make backup of efs.
4th follow steps to get custom rom working again
5th restore nand backup
6th if imei is lost again use backup.
I just wish there was an easy way to do it other than going back to old firmware

There is if you had made a backup. Unfortunately without a back, which you should always make, you need to take the long route...
I read that the app called Galaxy_S Unlock by Helroz can fix your problem. You need rooted phone.
I have flashed alot of roms and hav alot of efs backups bt all these are just logs. R they useful?

Nitrality app.
I don't think that app works with ics/cm9. Its unusually fast for. Backup. Almost like it didn't do anything at all. At backup and restore. It says done as soon. As I click backup or restore.

Look at your sdcard insanity/backup
just go to any CWM recovery and in backup and restore option, backup efs or vice-versa !
Hi, looking for some help if someone would be kind enough.
I wanted to try out Cyanogenmod. I made a backup in TWRP. Installed CM and played around for a while. Decided to go back to stock. Went to restore and the restore fails on data. I decided to see if everything else restores, so I unchecked data and everything else went fine. It's only the data that will not restore.
Anyone have any idea why that might be? I'd like to get everything back if possible. I read on another site I might be able to pull the TWRP backup and restore with titanium backup. Gonna look into that.
Any help would be appreciated, thanks.
If anyone would kindly tell me.
Currently my phone has a network problem where data disconnects every 5 minutes or so them reconnects again a few moments later. Network settings restore didn't work so I want to restore a backup I made a few months ago.
I know data couldn't be backed up earlier and can't be restored, but I'm only wanting the system, but I'm not sure how to go about it.
Should I wipe system then restore or just dirty flash system over top? Will the current data partition be affected in any way?
Phone is rooted with Magisk.
I'm planning on reinstalling many apps and their corresponding system/storage data using O&backupX afterwards as well.
Bump
It's been a long time since I restored a TWRP image, but I basically erased the phone then flashed the backup data over. IIRC, this didn't really work for me back then, as it left me with a non-working phone, so I gave up on restoring backups at all and just migrated data myself from the backup folder. In other words, I'd say you should reflash the ROM you want "fresh" and then just pull data from the backup as needed. But you can certainly try the restore first... you might have better luck than I had.
I think a wipe/erase is important as the backups aren't bit-wise images... back then, it was just file-copied over. For this reason, any stray files would not be removed with a dirty flash. It could work, in theory, but it is cleaner to wipe first, of course.

Hi, thanks for replying.
I guess I wanted to try migrate current app settings with the older backup but realize this may cause problems. I'll try wipe system and cache, then restore them from an earlier backup then restore apps and their data selectively. Cheers!
