Wiping and Nandroid - Hero CDMA Q&A, Help & Troubleshooting

Hello.
i'm curious about installing cm7. i know it requires a full wipe. i'm on cm6.
i've never wiped the phone before and i'm wondering if a wipe affects previous nandroids? if i wipe the device now, and then choose to reload a previous nandroid backup, will the wipe cause the backup harm? or, by reloading the nandroid, everything gets put back where it was?
does that make sense?
thanks.

the latter.

A nandroid backup is like a snapshot of the system, it will back up everything (except SD card). I have found that after a nandroid restore the phone even remembers where I had a song paused!

thank you, guys.
i'm gonna try to flash a new rom tonight without fear.

Yeah, you confused your steps a little. Seeing that you did a nandroid after all of the wiping, you essentially just made a backup of your boot, data, recovery, and system images but your cache image is not gonna contain much because you wiped I'm pretty sure. If you flashed your new ROM, you can't flash your nandroid backup as that will take you back to your old ROM. Nandroid isn't a back up tool in the way you want to you use (settings, preferences etc) It is a tool that will restore your system in case you mess something up. If you want the new drizzy JAC build, you just flash that and leave your nandroid for a rainy day or if you screw up a flash and get a bootloop.

Nandroid backup not working

i did a nandroid backup and tried restoring it, and it gets stuck at the bootscreen.

Did you wipe before restoring?
yup, complete wipe

I want to preface this by saying it is a guess.
Theory 1
Since the rom had written data to the EXT partition, when you wiped before restoring, it is looking for something on that partition???? You may need to start over with Kingklick. If you use Bart or Switchrom to do your backups, you should always be able to restore without need ing to wipe.
Theory 2
After you wipe (everything) make sure you "repair ext" from the recovery menu.
i did a BART backup and restore and that worked perfect

Nandroid won't complete a backup

I have been browsing google for an answer to this problem but nothing I have found has seemed to help, so I suppose I'll ask and see if anyone else has had this problem had knows what to do.
I try to run a nandroid backup from cyanogen's recovery, it simply keeps making dots and will easily fill up a screen.
Furthermore, i try and do a "nandroid-mobile.sh -b" and it hangs on the data.img part for in excess of 20 minutes.
Any ideas what I can try to get nandroid to work again? It has failed to work both on the last version of SuperD and on the newest which I updated last night (1.11?)
I suppose I could try a full wipe and reinstall, but I haven't donated for the full Titanium backup yet... and restoring is a pain until I do that.
Is there anything besides a wipe that I could try?
Thanks

I have the same issue using Amon Ra's recovery with Nandroid.
I end up pulling the battery and rebooting.
Take a look in your Nandroid backup folder on your SD card....you will see files that are several GB in size.
The nandroid appears to get stuck in a loop.
I have not had a successful nandroid backup made since CM-Recovery. I might go back to it but Amon Ra has a lot more stuff.
I reverted over to Amon Ra recovery from the JF+ Cyan one, and did a full wipe and restore of everything and nandroid was working well after.
Not sure what happened, but its all peachy now. I donated to Titanium backup, and it is the best app I have used... makes me want to switch Roms daily now!

Which Amon_Ra? I had the same issue on 1.5.x and 1.6.2.
Still no joy on nandroid or BART.

[Q] Droid 4 CM10.1 Stuck at Boot

My phone will currently not boot bast the CyanogenMod boot screen.
I flashed my phone several months ago to CM10.1 It was the update that patched the "masterkey" bug. I have been using it daily since then with no problems.
Today, I turn my phone on, and it just hangs at the boot animation.
There were no significant changes since the last time it was powered on. I think I installed McPixel from the humblebundle, and uninstalled a game from the playstore called Krog. No setting changes of any significance.
I've tried booting into safestrape and deleting both the cache and the dalvik cache, neither has helped. My stock rom still loads just fine, but i had factory reset it quite a while ago. I do have a backup of the rom from about 40 days ago i can try restoring, but i would love a more nondestructive way to fix this.
Try booting into safestrap, wiping system, cache, and dalvik, then reinstall the ROM and gapps.

0.o wouldn't that be a LOT more destructive than just restoring the old backup?

Nope. You are not wiping data so all your apps, setting, etc will still be there.
the data itself will remain if you just wipe the system, cache and dalvik cache but be sure to reinstall the latest stable build of CM and gapps for it

ah gotcha gotcha...
unfortunately it didn't work.
for troubleshooting's sake, i went ahead and made a backup of the rom in it's non-working state.
i restored my old backup, it boots just fine.
restored borked backup (tested it, still won't boot), wiped cache/dcache, wiped system, installed cm-10.2-20130821-NIGHTLY-maserati.zip and gapps 20130812, wiped cache/dcache again for good measure, then reboot and waited 10 minutes, still won't pass boot logo.
so i figure someting's wrong with Data right? so i rebooted to safestrap and did a factory restore, then wiped cache/dcache, and still won't boot.
so now i'm going at it the opposite direction. restoring the working backup, restoring just the data from the nonworking backup, then upgrading CM/Gapps
rebooting.. and....
blank screen with full backlight. not so much as a CM logo.
i guess for now i am going to restore back to the old backup, update the rom, and go about reconfiguring, unless anyone has any more suggestions?

Yeah, definitely sounds like something in /Data. Only other possible option I can think of would be to use Titanium Backup. It has an option to "Extract from Nandroid backup". It's under the "SPECIAL BACKUP/RESTORE" options. I've never used that option before so I have no idea how or if it would work but might be worth a shot.

wonderful idea, unfortunately TB crashes when i point it at either backup.
buuut i did find Nandroid Manager * ROOT which looks like it might be working.
if you really wanna see if it is the data or not have you tried to
flash 10.2 or whatever you started out with... then restore -just-
the data to the freshly flash system and then do a wipe of all
said caches... I do that sometimes to get a fresh start on my
os itself.. works pretty well. Just do not restore the cache just
the data part. Or restore with MD5 checking... if it doesn't check
out then you know for a fact that the data partition in that specific
nandroid isn't any good :/

[Q] Trying to unflash ROM - very overwhelmed!

Hi there,
I recently rooted and flashed a custom ROM onto my Samsung Galaxy S3 Mini. I'm very new to this thing and find everything quite overwhelming, but I want to learn.
I flashed this ROM - http://forum.xda-developers.com/showthread.php?t=2119219 (the v6 No Wipe version because I was petrified about losing my data if I factory reset), but the phone is now extremely laggy and buggy, so I want to go back to the stock ROM (so I can do a nandroid backup) and then try a different custom ROM like Dmod.
So, my question is, do I have to factory reset my phone to go back to stock? Or can I just flash this file (http://hotfile.com/dl/189271016/833...T-I8190N-BTU-I8190NXXALL6-1356151513.zip.html) using the CWN recovery menu without wiping? I'm asking because my phone keeps giving me an error everytime I try to backup using the CWM Recovery menu.
Thanks and if you need me to explain something in further detail, let me know.

That firmware is a zipped odin-file. Can't be flashed in CWM.
Make a cwm nandroid backup of your "/data" to your external sd (that's your installed apps)
You can also backup your apps and appdata using titanium backup or similar, for later restore.
Just remember to never backup/restore systemapps.
Backup internal sd to computer just to be sure, if you in any situation have to make a factory reset. Make sure any kind of backup is on your external sd before you make factory reset, or it will be lost forever

Backup your data in CWM, flash my ROM and restore your data with CWM.

CWM has NO choice to backup/restore only parts of the device. Only a full backup is possible.
This is only in TWRP. Pity! I only use CWM because TWRP makes corrupted backups (three times) for me.
Or is it possible to pick out only DATA from the backup? And what is happen with the dalvik cache, which
consists of the byte-code for all installed apps, optimized for the ROM which created it?
"advanced restore and restore only /data". Is this the way in CWM that you mean @benz?
JackoMJ
Yes that's exactly what I meant, "advanced restore and restore only /data"
You don't have to worry about cache and dalvik because it's automatically created on the initial start.
thx for the information Benz (usefull in the future perhaps),
but i´ve decided to use Titanium Backup.
