I searched high and low and can't find a definitive answer... Am I supposed to wipe cache, dalvik cache or anything else prior to restoring a nandroid backup?
Thanks for helping a noob out.

select the backup you wish to restore and let it do its thing
then reboot
DONE
no need to wipe anything at all...
but just for warm and fuzzies i would make sure that you have the engineerring bootlader, AKA 85.2007 and not the 86.0000 just in cause something unforseen happens, as there has been an influx of problems with mount errors and FAIL PU errors, just my 2 cents

I wipe everything prior to to using the backup. the nandroid contains all system files(apps,etc) so I wipe to get rid of rom in use.

this is not needed as the nandroid is like a picture of your system as a whole when making a backup... so restoring a backup wipes your entire system back to the state it was when the nandroid back up was made... but if that makes you feel warm and fuzzy then my all means do it your way, i used to do the same thing you stated until i did my research and found that is is not needed, and have never had a problem since not wiping prior to doing a nandroid restore!

+1 - I've never wiped before a restore, but have done countless restores. Don't worry about it.
Hi everyone, I recently rooted my 16GB WE TPT and installed cm10 v.0.8.1 and I love the performance and everything, if only there were no reboots. After reading in this forum I wanted to try to reinstall things from scratch wiping everything. For some reason I don't seem to be able to to anything with the data that is on my TPT. Neither can I do a factory reset from settings nor can I wipe data from Recovery. It doesn't display an error but it just doesn't delete anything. Then I tried to restore my backup from my original rom but this doesn't work either: it says error while restoring data (after recovery and system).
Can anyone help me? Could I have accidentally locked the data or anything?
Btw, Google Play has stopped working after my last try to restore stock and then install cm10 again.
In cwm you find under advanced a setting called "fix permissions". Try that

Hi, i had big problems with my Data-Partition. The Partition was read-only. No wipe with CWM was possible. Is that the same problem what you have? Do you have an logcat? Any error-messages?
Wiping was only possible with adb...

I don't have the same error messages you have/had, but I could image that my data partition is also read only since I can neither delete or install anything. What did you do to get rid of that problem?
The solution was to completely format the data permission. This can't be done in CWM directly because CWM tries to keep the folder /data/media, which is your internal sd-card and only deletes the other files (That's obviously not formating). In the link you can find a zip files that you can "flash" in CWM, it will format the data partition and does nothing else. After using it you should also manually wipe the cache using CWM.
Like i said, this will include your internal sdcard! Make backups first if you have important data stored on it!

I need to clear it - if I do "wipe data/factory reset" in stock ICS recovery menu - will it cause deleting ROM (and reboot will make brick) OR just will get it back to clean factory ROM?
I found few threads here about "wipe data"-thing, but it seems to me, that every version of Android / custom ROM / recovery type could behave different.
Hi,
I tried to install CM10 on my Motorola Defy+ (MB526), which was successful to some extent.
When I tried to install the latest gapps through CWM, it froze at the starting applications part.
I force restarted it, seeing that there was no change for a while.
When I restarted the phone, it kept on rebooting, with limited functionality, so I downgraded to CM9.
An error message pops up which says with Encryption Unsuccessful. A reset button was available, but didn't help.
I then re-upgraded to CM10, but the phone has limited functionality.
After researching the problem, I realised that the /data partition is not mounted as it is probably corrupted.
Is there any fix to this problem? Will flashing a sbf recreate the /data partition?
Please advise as the phone is basically useless without /data (no apps and constant reboots)
Thanks,
neiljain

Hi Buddy,
I went through the same process last evening, earlier i was on 2nd boot then it was very slow hence I decided to move to CM9 for better UI and good battery life. but while doing so my phone also got encrypted.
I did following and installed CM9 yestrday night.
Removed SD card, read it through computer (CArd reader) and put CM9 in one folder along with GAPPS.
Charged my battery till green light pops up.
Entered the SD card again and then started the phone in Custome Recovery.
Full data Wipe
Dalvik Cache wipe
Install CM9 and Gapps.
again clear Cache and dalvik and reboot.
It should work, let me know if it doesnt work post that as well.

If the /data partition is corrupted (which I believe it is), will this still work?
Also, did you get any "Can't mount /cache/recovery/command" errors in CWM at anytime.

Boot to recovery and turn on adb (in Advanced). Open a shell on the phone through adb from a PC. Try to find out if data is mounted, and if so what filesystem type it uses:
Code:
$ adb shell
~ # mount|grep /data
/dev/block/mmcblk1p25 /data ext4 rw,nosuid,nodev,noatime,nodiratime,barrier=1,nobh,data=writeback 0 0
If /data is corrupted it will not be mounted. On my phone /data and /cache are formatted ext4, which is only supported in the latest CM10. If yours happens to be formatted ext4 as well and you want to go back to CM9 you'll have to reformat both to ext3. If /data is corrupted you can also reformat the filesystem as you don't seem to have data worth keeping on it anyway (seeing that you talk about doing a full SBF flash to 'recreate the /data partition'). This can be done manually or - if you have not nuked the scripts installed by CM10 - using one of the scripts made for that purpose. Those scripts live in /system/bootmenu/script:
Code:
~ # ls /system/bootmenu/script/|grep format
format_ext3.sh
format_ext4.sh
If you have access to these scripts you can just run format_ext3.sh to reformat /cache and /data in ext3:
THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST!
Code:
~ # /system/bootmenu/script/format_ext3.sh
If you don't have access to them you can achieve the same effect using the following commands:
THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST!
Code:
PART_CACHE=/dev/block/mmcblk1p24
PART_DATA=/dev/block/mmcblk1p25
umount /data
umount /cache
# if you want to check the filesystems you can run these commands...
#/system/bin/e2fsck -y $PART_DATA
#/system/bin/e2fsck -y $PART_CACHE
# to format the filesystems to ext3 use these commands
/system/bin/mke2fs -j $PART_DATA
/system/bin/mke2fs -j $PART_CACHE
mount -t ext3 -o nosuid,nodev,noatime,nodiratime,barrier=1 $PART_CACHE /cache
Once you have formatted /data and /cache you should be able to install CM9 - no need for any SBF flashing unless your phone is really messed up (as in 'deleted the stock kernel' or something like that).
THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST! Or did I say that already?
No matter. THIS WILL FORMAT YOUR DATA PARTITION - ALL DATA WILL BE LOST! Just to be clear...

SBF flash and data wipe in stock recovery should work too...
The other method is a bit more nondestructive, but probably harder for you

adb is the Android Debug Bridge, a program running on both the phone as well as your PC which makes it possible to access your phone (through either a command line shell or some GUI-thing layered on top of it).
Are you also new to Linux and/or computers in general? In that case you're probably better off flashing the phone as detailed, even though that takes way more time and does involve more risks. If you feel comfortable running commands from a command line I'd advice you to install the ADK (Android Development Kit) on your PC, get adb working and run the commands as I explained. That way you regain access to your phone without all the hassle and risks involved in flashing all the way from SBF. Both methods work, so the end result should be the same.
I'm intentionally not going into excruciating detail on the task of installing and running adb as I don't think you should use your phone as a guinea pig to start experimenting with adb - for that use the emulator which comes with the ADK.
Success
Hi Everyone,
Thanks for your very helpful suggestions.
I was able to recover my phone after flashing the SBFs
Just to be on the safe side, I will stick with CM9.
I will also post the instructions on XDA for other people who have the same problem.
Once again, thanks everyone,

Thanks Buddy, I too stick to CM9, which is giving best battery 2 days and awesome UI. will move to CM 10 once we have stable version.
Njoy your Defy.
how were u able to flash any file... neither the bootmenu nor the recovery is working... please revert back.
So I've been using various JB ROM's on my Defy for the past couple of years, but this time I made the mistake of using the factory reset within the stock recovery. I found a thread that mentioned using the "ultimate wipe" for defy and then reflashing my ROM of choice would fix issue, but when I use the wipe the custom recovery still tells me it is unable to mount /cache or /data on my phone.
My phones internal storage is also showing as 0, so I am unable to install any apps etc.
I'm completely stumped right now, so any help at all would be greatly appreciated. I'll provide any further information I can if its needed, thanks in advance

Your partitions might have a problem and the wipe script doesn't format them, it just deletes their contents. In the bootmenu you can format your /data and /cache partitions (ext4); if that doesn't work, then yes, gotta start over from SBF.

Thank you heaps for the help. I just decided to go ahead and reflash SBF. That all went fine, RSDlite gave a pass. I then went into the stock recovery in order to do the factory reset again before I root, and Data now formats, but Cache throws up the error "E:Can't mount CACHE:recovery/log".
The actual phone seems to work fine if I boot it up, but that error just makes me wonder as I'm not sure how much of a problem it really is
hello there!
some months ago i tried a custom firmware on my 9506 (i think that was the first version of arya mod) but i didnt kinda like it so i downloaded again the stock fw and flashed it back.
i did my typicall "download the basic apps" routine and on the 4th app an "insufficient storage available" message appeared on my screen and i was like "lol whats wrong?" i checked on and i found that 10.6Gb was used by system.
Well i thought that i downloaded maybe a bugged stock rom and i didnt have the free time at the time to check whats wrong so i decided to live with it till i find some spare time to check it again.
Yesterday i downloaded and flashed the lineage os fw and i was sure that this would fix the problem...but...well it didnt..still 10.6 used by system.
i tried wipe EVERYTHING (dalvik/cache/system/internal) and reflashed again but still nothing,i flashed again the stock rom,still nothing, i searched online but i didnt find a solution, i downloaded diskusage app to see where are those 10gbs but i couldnt figure out where they where.
So if anyone knows anything or had the same or similar problem it would be great if he/she write here and give a solution or some tips.
Thanks in advance

Try flashing the stock ROM together with a PIT file
i fixed it guys
i flashed again cwm recovery and i formated EVERYTHING from there and then reflashed again the rom and gapps and that fixed the problem.
Thanks for your help !
For the record, CWM's incremental backup feature was what I believe was stealing your space. If you still have CWM on that device, make sure to set the default nandroid backup format to ".tar" instead of ".dup", clear out your nandroid backups, clear all the allocated space, and then upgrade to the latest version of TWRP.
CWM hasn't been updated in a few years now and has difficulty installing modern ROMs.
you are right i think.
if i recall corectly when i flashed that rom back then before the problem appeared, i used cwm recovery so yeah maybe thats the main reason that this happened.
i allready set the default backup to .tar and cleared out all the nandroid backups and i allready use TWRP now.
thanks for the tip mate!
