I am currently on CWM touch recovery v14.4.6. If I want to a restore a nandroid backup, do I perform the following steps before I hit the restore button?
1. wipe data/factory reset
2. wipe cache partition
Any guidance is greatly appreciated.
Sure why not

If you're restoring a nandroid it doesn't make any real difference what you do. As long as you don't wipe the the nandroid

For a full restore I wipe system/data/cache. I've never had a single issue restoring.

Thanks for the response. I don't see the wipe system in CWM touch, only factory data and cache.

It would be format system in cwm if I remember right. Haven't used cwm since twrp came out.

Thanks Xcrazydx! So, is doing a format/system the same as wiping system?

Yeah it's the same. So I should have said I format system/data/cache. Do those and you'll be fine.
Just remember that you have to flash the radio separate if you need to change radios. Nandroids to not contain the radio / modem. If you want to keep the same radio / modem, then you won't have to do anything except flash the nandroid.
I have problems restoring lately. I use sk8ers cwm latest and when restoring I get system could not be restored. I did backup pre load. I use the externel SD card to backup. Md5 sum checks out fine or appears to check out fine.
Normally I wipe just as if I was installing a fresh rom before restore. I have restored backups without wiping and they work fine. Just gives me piece of mind especially if I encounter any issues.

Have you resolved the issues? I got error messages when I tried to do a nandroid backup with preload option checked. So, I decided to do a normal nandroid leaving out the preload and got no errors. I haven't tried to do a restore yet afraid that I might have the same issues as you.
I do believe that my backups got corrupted maybe from just not unmounting from pc properly as I just un plug it most the time. I lost the backups but still got titanium so no big loss. I change roms like I do underwear.

I've always had problems backing up/restoring from external SD. Try moving your backup to internal SD, should work fine.

Surely this question has been asked dozens of times, but given the brickbug I'm not sure if there's a better way for our skyrockets.
I'd like to try out the new Chimera, coming from SkyICS. Would it be best to format everything and do factory reset, inside CWM or to restore my backup right after originally flashing CWM with stock 2.3.6?
Thanks

Went with the restore, no problems. I'm oblivious as to how to wipe the actual data which includes all the prior apps. Wipe Data/Factory reset didn't work. Do I need to just format SDCard in CWM to get rid of everything? Or is the main mount the /emmc?
Only thing I found with looking around was just deleting everything while mounting to PC. Went with that but it only deleted about 700mb. I know I had a couple games installed that took up ~1.5gb total, so I must assume 1 was deleted at some other point.
quck and easy one, when doing a nandroid restore do i need to wipe all partitions or just go ahead and do it?
Yes I Always wipe before restore . Also wipe cash and dalvik, I also factory reset and stay in recovery upon completion to restore . Then reboot. This gives a clean installation. You're making sure the old Rom is gone before restoring. Hope this helps. If I'm in doubt I always wipe. Just to be safe. Remember even though is a backup, your still coming from a different Rom. So you will want a clean installation before restoring. I do my restorations this way and had never had a problem.

No. It does that on it's own.
What you are supposed to do though, is search before posting a new thread.

Hi,
No need to wipe before restore.
The whole point of a nandroid is to wipe what's currently there and restore the backup you made. Wiping before restoring is wasted time/power/flash writing.

Helllo everyone, I have problem in restoring nandroid backups generated by CWM 5.0.2.0
When I restore backup, I get boot loops and cleaning up dalvik cache and cache wont help. First i thought it maybe a random error but it has happened even after lot of tries. I dont have a faulty sd card.
The backup i was trying to restore was of oxygen 2.3.2 with a theme installed + some apps
Can anyone suggest a a solution?
If you are getting bootloops then sorry to say the backup is not a healthy one, you need to reflash ROM. I also had problems with themes installed, now I made a backup keeping everything stock with apps.
Oxygen has inbuilt app2sd script. This causes problems many times. I would recommend restoring the system first, boot it up den restore both data and sdext.

Switch to twrp or amonra(if I'm not mistaken amonra can restore cwm backups).

You could have an error, like bad block, in your internal memory. To rule that out, install some other ROM fresh & see if you get errors.

If the backup isn't restoring, then you should try restoring the backup, then reflashing the rom. I would recommend switching to amon ra recovery or twrp since they don't have that problem and imho they're better.
It seems the theme I installed had some problems since they replace system files such as framework-res.apk , settings.apk etc.
I flashed clean oxygen, installed lot of apps, created and restored the backup and it seems to work flawlessly now.

Hey guys...
I have been using EHNDROIX custom rom for quite some time. For no apparent reason now when I try to boot my phone it freezes on the logo screen. I tried installing newest or oldest updates, or even other custom roms but I still face the same problem. I was wondering if there is a way to bypass that problem without losing my applications. Do you have any suggestions on what to try apart from wiping cache, dalvik cache and fixing permissions (which I've already tried)? Can I backup my applications from recovery before wiping data which I suppose will fix the problem?
Titanium bkp will let you restore app data from a cwm backup (may only be a pro option)

You can wipe data without losing your applications. You would have had to run a titanium backup before you got stuck in your bootloop scenario. TB pro is the best $6 I have spent on the market.

Hi,
Titanium backup can restore apps from cwm backups.
But also, if your using the test cwm recovery (version 6.0 or above I think) and you will be flashing the same rom again, you can go to recovery, select advance restore, select your cwm backup you made earlier, and select "restore data only"
That will restore all your data you had on the phone, like apps, app data, call logs, ect.
But you should really be on the same rom that you made the backup of to do this, or else it can cause more boot loops.

That sounds really interesting..Thanks for pointing it out!
I have what seems like a very basic question on backing up using TWRP, and yet I havent been able to find this anywhere in the help threads.
When I am creating a backup it asks for what I want to backup: System, Data, Boot, Recovery, Cache, .android_secure.
Which of these do I want to make sure are checked? The first backup I did I left the default (which was only System and Data) and now I am unable to restore to that backup (I just get a blank, dark screen). Looking through the forums it seems I may need to flash boot.img in order to restore?
So does that mean in the future I should make sure to also check the Book option when I create backups? Any others?
Thanks.
system, data, boot
leave the other 3 unchecked

Thanks again for all of your help over the last few days!
Would the failure to check Boot on my first backup be the reason I am getting that blank screen when I try to restore? And is this fixable by flashing "boot.img" if I can find it somewhere?

You could probably just flash the same ROM you made the backup from and then just restore the data from that backup through TWRP. Then you'd be back to the same setup you tried to backup originally, right?

If you want your backup to work after you do it - don't touch the default selection.
And this is also the reason you don't see any threads about it. All those who don't understand what each partition does just don't touch anything, and all those that understand don't write about it.
Read more to see why the first suggestion you got (system, data, boot) might fail you.
Backing up recovery in recovery is useless, though.

My initial backup was made just with the default - first two boxes ticked. Unfortunately I now cannot get that backup to recover and boot, which is why I am asking. What else might be the cause or how would you suggest I try to solve?
Also, apologies but I dont understand what you mean when you say "Backing up recovery in recovery is useless, though." Do you mean this isnt the best way to make a backup/nandroid to recover to?
Alright, here's a short explanation to get you started:
/boot - your kernel partition. Without it the ROM won't boot.
/system - your ROM.
/data - user data, all the apps and app settings that user has.
/.android_secure - all the apps that are on SD (or USB storage).
/cache - temporary place for storing downloads, exchanging data with recovery and such.
/recovery - where your recovery resides.
From this you should be able to understand why it's useless to backup recovery partition - you won't be able to restore it if you don't have custom recovery in place, and if you have custom recovery in place - you don't need to restore this partition, it's already populated.
This should also tell you why you need .android_secure. Some apps are still installed by default to SD card, and these will be lost if you don't back it up.

Thanks. I think I misunderstood your initial post. When you said "system, data, boot" advice might fail me, I thought you meant NOT to backup boot. But I think you meant to ALSO backup .android_secure, not to avoid backing up boot.
When doing a recover, is it generally advised to do full cache, davlik wipe and factory reset, like when flashing a new ROM?

Only erasing boot? So the only thing that remotely connects to what you're saying would be boot.IMG which is the kernel in which case you would be incorrect. Please if you plan on correcting someone at least be concise so people understand the point you are trying to convey.

LOL. Can't we all just get along.
Since I'm not one to speak for others I'll only guess that what he was trying to get at is restoring only erases the boot.img. It then restores boot.img, system, data, android.secure, and cache. So in theory it doesn't actually erase any of the remaining partitions. It just writes over them. Whether or not this leaves any residual parts of any of the partitions has been a source of debate for quite some time. If it does format the partitions before restore there is no indication textually that I have seen.
Carry on.
EDIT: I might as well point this out before some one else does. The restores I stated above where done from CWM not TWRP. I forget what the thread was originally about. For that I apologize. The logic behind the post stands for either recovery though.
