Nexus 7 - Cyanogenmod bootloop after backup with Titanium Backup - Nexus 7 Q&A, Help & Troubleshooting

So first of all, sorry for being a total noob about this so please help me out.
I flashed Cyanogenmod 10.1.2 onto my Nexus 7 4.2.2 and everything was going fine. After all of that was done I installed Titanium Backup Pro and restored all my Apps including the data. When that finished, I was told to do a reboot for it to take effect, and so I did. But the problem is that it stays on the Cyanogen (splash screen/boot logo?). I have tried wiping the data (data, cache and dalvik cache), but it doesn't seem to work. Everything works well until I restore and reboot. :crying:
Help, Have I done anything wrong, or have I missed a step?

i have the exact problem, for some reason when i restore "missing apps + all system data" i cannot rebot my device, the only backup working forme right now is just restore all app, no data .

You can't restore all information backed up across Roms. Only restore app data, use play store to reinstall all apps. This should resolve the problem.
Sent from my Nexus 7(2012) that has zero issues.

You're confounding variables here... you're trying to use TWRP like Titanium (apps/data).
TWRP (like CWM) is a MONOLITHIC backup system, pretty much everything gets restored. Titanium is GRANULAR... and selected apps/data are restored WITHIN the ROM you've just flashed... not OVER THE TOP of the ROM, as you've just attempted to do... which will cause no end of problems.
--------
Here's what I would do.... restore your NANDROID backup as normal (factory reset, etc.)... Get TITANIUM from PlayStore. Backup your apps/data using that.
Flash your ROM... restore your apps/data using TITANIUM.
Rgrds,

Made backup in TWRP 2.3.4, won't restore in 2.5.0

Any ideas on this one? I don't get any errors on the restore, but I am stuck on the eye every time I boot. I have tried wiping cache and dalvik cache.
About to just restore from Matt's tool, but this has me worried, you know?

Well, have to say, thanks matt. The included RSD helped.
I forgot I was also restoring stock over CM10, which may have also been the issue, but I am back into the phone now.
You shouldn't have issues restoring backup from the older version, and you shouldn't have issues restoring a stock build over CM. Did you use the restore option or did you try to install the backup?

I have no idea what caused the issue. I did a backup of CM10, wiped data, cache, dalvik, and system. Hit restore on my old Stock backup (created in TWRP, not safestrap), wiped dalvik and cache again, and rebooted (and allowed TWRP to fix root first). It booted to the droid eye, but then just hung there for about 10 minutes.
I used Matt's utility to restore the system and it failed (tried to install the same part of system over and over again, 3mb in 4 seconds, 100k in .4 seconds, over and over again). So I had to force stop that and use RSD which worked fine.
No idea what all that was about.
So I think I found the culprit. My backups from the older version of TWRP don't have BOOT, only SYSTEM and DATA. So I was probably having my stock rom install while the CM10 BOOT was still in place.

[Q] [SOLVED] Cyanogenmod 10.1.2 Reboot Stuck in Boot

[SOLVED] Hello,
This is the first time for me posting in a forum asking for help about an android device so go easy. I have rooted my Nexus 4 running Android 4.3 and installed TWRP 2.6.0.0 on it. That was the first time I rooted an android. I used Titanium Backup (Pro) to backup all of my user apps + system data. Then I transferred the backup to my PC. Then I created a nandroid backup using TWRP. Then I cleared the cache, dalvik cache, and factory reset the phone using TWRP. Then I installed Cyanogenmod 10.1.2 mako, which is marked as stable, along with the Gapps found on Goo.im. It worked successfully and I set up my brand new ROM. Then when I restore using TiBU, it restores successfully until it gets to about 70% where it begins telling me that "There was a problem parsing the package" or "x App not Installed". TiBu then instructed me to reboot in order for system data to take effect after the restore, and I follow that order. Finally, my phone gets stuck in the boot animation of Cyanogenmod. I've gone in to recovery and did the entire process of flashing the CM ROM again and the same thing happened to me again. So I just restored my nandroid backup and now am on the stock ROM again. I've tried to look online but could not find any solution or reason. Remember that this was my first rooted Android device and I am not a pro at this stuff. I'm not asking for how to get out of the boot animation (I already know that), just why this problem is occuring and some possible solutions. Thank you.
I think the reason might be that you are not supposed to restore apps when changing from one ROM to another. I read that somewhere online. Is that true and do you think that that could possibly be the case? I went from stock ROM to CM.
[SOLVED] i have found the solution. it was that i tried to restore system data which caused the problem. everything is great now!

Help with TWRP Restore !

I just got a s5. And I got it succesfully rooted and also got TWRP working on it.
All the data from my previous phone was transfered to the s5.
Now I made some backups with TWRP with the default settings: Partitions boot, system and data.
With the backups in mind I was thinking I could easily restore it to a previous state.
Thinking I backed up all the data and wanted to make it fresh again, I wanted to restore it.
In the menu I chose the restore option with the same settings as the backup: Partitions boot, system and data.
And it gives a message restoring system succesfull.
But when rebooting, it keeps hanging and at the moment of loading the android system every bit of the system keeps 'hanging'
It keeps saying
'Unfortunately touchwiz startup unsuccesfully'
'Unfortunately youtube startup unsuccesfully'
'Unfortunately greenify startup unsuccesfully'
'Unfortunately app whatever startup unsuccesfully'
And so on and so on
Eventually it starts with a black screen with nothing loaded. Complete blackout.
So this backup doesn't work. And I try my second backup.
Unfortunately also the second backup gave these errors.
And also the third backup!
So the backup files seem the right size, it's some gigabytes, and it alway's keeps saying backup/restore succesfully.
But now it fails to restore and boot the backup
The things I tried.
-Trying three different backups
-Wiping cleaning data/dalvik/cache etc etc
-Restoring a part of the backup. First system, then data, then boot, no succes.
So i'm totally lost! Does somebody know how to fix this? Or have some tips to try??
You can't restore system and boot from a different model phone
That would be like trying to flash a ROM for one model phone to another without porting it
If it was an S5 you backed up, was it the exact same model (ie: G900F etc?)
Flash back to stock, then try restoring only DATA
Or use TiBu to restore your apps from the TWRP backup

Thanks for the reply! It was a backup and restore on the same phone. So that is why I thought it was supposed to be a easy restore.
But I found the solution hidden somewhere in one message on XDA:
"Originally Posted by Dr. Fed
Would you happen to know why, when restoring a TW 4.4.2 nandroid using TWRP 2.8.1 or 2.8.4, after running an AOSP lollipop ROM like CM12, the TW ROM boots but then the whole system force-closes? Before restoring the nandroid, I advance wipe system, data, cache, and dalvik. Then I restore the nandroid. It boots, but then some daemon crashes. Then all processes and apps. The screen goes black after a few crashes.
So, what I do is pull out the battery, boot into recovery, advance wipe system, data, cache, dalvik, flash a CM11 ROM, reboot. I let CM11 start up, skip the set-up, then I boot back to TWRP (2.8.1 and now 2.8.4), advanced wipe, restore TW nandroid, and now it works just fine.
It seems like TWRP doesn't fully wipe."
Here the steps for if other people will run into the same problem:
Problem: Android 5 is running, with twrp 2.7 performed a back up = Restoring the backup is difficult because it problably doesn't do a clean wipe somehow.
1. I downloaded a cyanogen 11 rom, a Android 4 version.
2. Installed it with TWRP. Somehow it 'wipes' it more efficiently.
3. From cyanogen 11 back to booting TWRP.
4. In TWRP trying the Android 5 restore.
And Amazingly this worked!! = Celebrate!!

Lineage stuck on boot loop on startup

Hi,
I have LineageOS 14.1 installed on my Moto G4 Plus. All of a sudden it rebooted and was stuck on the booting screen. I can get to TWRP. Things I tried that didn't help
wait 30 minutes
plug in phone to charger
clear cache
fully power off then on
If it comes down to it, I could flash a new ROM, but would like to save/backup the text messages/whatsapp messages.
@lightningglasses
Anything you installed/flashed before rebooting ?
try to dirty flash ROM and check if it boots or not.

wiping "Data" deletes everything, dirty flashing does not not.
Just wipe delvik-Art and cache (*not data*), Then install ROM (plus gapps and root if you need), reboot, it will take around 10 minutes to re-generate delvik data, then it should boot..

I forgot to mention in previous post, did you wipe system? Try with that and install rom.
Reinstalling ROM heals damage made to /system partition and to boot, but not to /data.
so if still doesn't boot, that means damage happened to /data and you need to clean it, result in lost of data of apps (whatsapp and message you mentioned in your post.)
Still if you know what apps you installed last, delete it from /data/app/xyz-app (boot TWRP > advance > file manager)

It is still stuck in a boot loop after I
cleared cache, dalvic/art and system
used twrp's file manager to delete all recently installed apps from /data/app
flashed newest lineageos rom
clear davilink again
waited 15 minutes with phone plugged in
When should I wipe cache/dalvik/system? Before or after flashing rom?

There is no other way to get your device back without losing data.
I have never used Titanium backup app but i know there is feature to restore data from TWRP backup, you can take backup of /data and restore backup of whatsapp.
I am still not sure about that feature, if you have time then i can test that feature, otherwise there is no way to keep data.
Edit: whatsapp makes chat backup every night at 2AM, if you haven't had any important chats after that, you can go for wipe.
If you can pay for titanium backup there might just be a way. I am not 100% sure but take a backup of the "data" partition(you can backup everything but data is most important) in twrp in internal storage only. Then clean flash everything. Then install titanium backup and buy the pro key. Then restore from twrp. If you find an option to restore only data then that's a better option. Downloading the app and restoring the data is better than restoring app and data. I'm not sure if it will work. But if nothing is working and your data is 100% vital you may wanna try this.
Another tip, don't restore blindly everything cuz bootloop may occur again
