Hi guys. I'm using the 2.6 version of TWRP. It seems whenever I restore a backup things always seem to go wrong and the OS reboots the first 24-48 hours before things are eventually stable. Do I need to factory reset and wipe system, cache and dalvik cache before I restore a backup, or should restore simply take care of everything for me already when I'm switching from one ROM to another?

One of the reasons I don't backup.
But, yeah I suppose you would want to clear data and cache before you flashed a backup.

You should always wipe cache, data, system, dalvik cache and do a factory
reset before restoring a nandroid backup or flashing a new or different rom.
Doing a factory reset before restoring a nandroid backup will not make
you loose anything at all because the nandroid backup contains all your
settings, apps, mms, contacts and anything else you had in your rom
prior to making the nandroid backup.
It would also be best if you went to the play store and download the free app
"Goomanager" and use that to make sure you have the latest version of TWRP
for your phone.
Good luck!

So I have a quick question for everyone here.
Is there anything else I need to do to clear all remnants of an existing ROM from my phone other than factory reset/wipe data and wipe cache before installing another ROM?
I seem to have residual bugs from a previous ROM on my current ROM. Maybe it's kernel related? I don't know. Any advice?
Edit: Gah. Sorry wrong forum. Please move.
Try wiping dalvik cache from recovery. Its in the advanced tab i believe.

What i usually do is go into the partitions menu and format data / system / cache, and then i go into advanced and format dalvik cache, and then i go to the main screen and do format data factory reset and then format cache... i do all those twice so its 100% gone absolutely nothing lingering around

Awesome. Thanks guys. I'll give that a whirl.
I have been checking the box in ROM Manager to clean cache and wipe when flashing new Roms
and then ... ?
After all this is done, and the new ROM flashed, what can one restore from Titianium Backup without restoring incompatible/bad stuff? Thanks

Don't restore system data, especially if you're going from a 2.1 rom to a 2.2 rom.
I always just restore user apps and data.
Id like to try viper 2.2 rom currently im on stock with lost kernel. If I flash viper rom should my cwm 5.0.2.3 restore to stock just fine from my nand backup..?
Any certain measures to take prior to restore..? Or just data / dalvic cache wipe?

yup as long as you made a backup prior to flashing viper
you can go back without issue
i normally format system and cache and wipe davlik.
or factory reset wipe cache and davlik for a full restore (apps too)
the nand is a complete system dump including all apps and everything so you can do a nand restore of everything but data which is your installed apps to keep anything you downloaded since then if you dont wipe data
or just do a full nand install and it'll put on just whatever apps you prev had
I tried out a rom and really didnt like it. I made a nandroid backup before hand so would I just go into recovery and restore or do I need to wipe anything first like delvic cache or factory data wipe?
wipe dalvik cache the other cache and wipe data factory reset. then restore. or you could flash calkulins format all.
Well I actually already did it and I just did the restore without wiping anything. Everything seems to work fine I will wipe cache and delvic but do you think I could get away without the factory restore?
A Nandroid restore completely overwrites everything with the backed up files. No need to wipe anything it is done automatically.
Awesome, thank you very much!

Hello,
I have an Amazon Kindle Fire with gedeROM v1.7. I love the updates because it makes my device better and better.
But can i update my device without data wipe so i don't have to reinstall and reconfigure the entire device every time. And if I can can someone please tell me how.
My usual procedure is download file, data wipe, clear davlik and cache, flash, wipe cache restart and wonderfull a better device. But all the data and apps go with the wipe so any help would be awesome!
Thnx for all the help!!

If you're not switching to a different ROM (ie, from CM7 to CM9, or from hashcode to energy...) then you can optionally skip the data wipe (factory reset), which will retain your data and applications...
Alternatively, you may want to take a look at Titanium Backup.
Thnx for the info.
I have been hearing a lot about Titanium Backup, can you give more info about the program.
With TB you can back up any apps on your device. Then when you update a rom just download TB again and then you can restore your apps that you backed up. I love TB and use it on every device that I have rooted. It is a lifesaver!! Ok maybe a time saver anyway!! LOL!!!!
I had a REALLY bad experience from not wiping everything completely. I'd definitely do a backup, like Titanium or MyBackupPro, and wipe it all just to be safe. To many goofy things can happen if you don't.
It really depends on what ROM your flashing. There are rare occasions you can cross flash without issue. Not recommended. Just updating the same ROM so wipe is necessary, unless mentioned by the dev.
If you do wipe than BUYING titanium backup is the way to go. The free version doesn't auto install apps, each needs confirmation.
I can get any ROM on the kf or my gnex but up and running in less than 15 minutes.
this is what I have been doing and I am not sure if it's bad to do or not. I make a backup of just my data using twrp, then I wipe the caches and do a factory reset. Then I install the rom, and then restore my data using twrp

Restoring your backed up data is akin to not having done "factory reset" in the first place.
You shouldn't encounter any major issues so long as you're flashing newer versions of the same ROM and there hasn't been a large change (for example, switching to linaro).
Hey,
I an trying to wipe my ROM and reinstall a fresh ROM. In TWRP Recovery, if I hit wipe system and data wipe, will that effect my back-ups on TWRP? Trying wipe the current one and restore the very first backup after installing the revolution HD M8 9.1 .
Only wiping Internal SD will wipe twrp backups. So wiping system, data and caches should be fine.
Sometimes things go wrong though. Good to have a backup of a backup off the device. And/or another rom zip. Titanium backup backups are good to store off device too. And pics, etc.
Bad things happen... And it's a drag when all your stuff goes away. :good:
Storing things as backup on an external sd is good too... But not fool proof either.

Agree to all the above. Always give yourself multiple ways out of a jam; and taking a few minutes to backup off-device is a great way to avoid regret and headaches.
