Cant boot anymore... - Nexus 4 Q&A, Help & Troubleshooting

Hey fellows,
I got a little problem with my phone. I tried to run some benchmarks on it and wanted to reboot, but then it stuck on 'Starting apps'.
To my phone:
I run the latest P.A.C. Rom with Faux Custom Kernel. So I tried to clear Cache and Dalvik to get it to run, doesnt fix anything. I tried to flash the Rom again, once without Faux Kernel, the other time with, doesnt fix the problem. Then I restored the system partition from a very old backup of the same Rom version, the same...
Finally I restored the old data partition of my backup and it works, BUT the status of this backup is too old.
So I did a logcat and it says: WifiStateMachine ... NOT_HANDLED and this goes on and on. I can see that all functions have been loaded in the background, but it doesnt go further than this screen.
Hope u guys are enjoying your holidays and can help me.
Thanks very much

Logcat??

Dont worry!
Just dirty flash the same version of rom and kernel again. You wont lose your data or apps.

I tried that a hundred times buddy, didnt work..
I restored my old backup and Im trying to restore all my apps + data from the broken data & system backup with Nandroid Manager. He finds the apps to restore out of the nandroid backup and tries to load the information of the apps, but after a while he says that no apps can be found...

Android gets stuck at starting apps when you undervolt too much and it corrupts your data only fix was a data wipe and reflash rom for me

I went into recovery mode and cleared my dalvik cache and things came back to normal. However, random apps still fail like Google Maps search.

Some super-simple noob backup questions

Quick and to the point:
1. Is a clockwork backup a full image of the system, such that if I restore from it no matter what kernel, rom, mod, etc. I've installed, I get exactly the completely system and state that I had when I made the backup? I.e., it is a true failsafe against messing up the phone, so long as CWR will boot and the SD card is intact?
2. A complete backup with Titanium, backing up all apps and system data, is a migration path for trying a new ROM? IOW, I can simply do a complete backup with Titanium, wipe wipe wipe, install the target ROM, then restore "missing apps and data" from Titanium and -- voila! I'm on the new ROM, but with all my apps, configuration, etc. I had before?
I'm getting ready to try out the Syndicate ROM...

Ha! I am searching now for the exact same question! I am looking to try the Epic Experience. I will follow this thread to see what the answer is.
Thanks.
First off might I comment that Syndicate Rom is a great choice. Not just saying that cause any of them are my buddies either, cause IDK Any of them... so far though Running Syndicate Rom/Kernel with SetCPU at 200-1200 has been the smoothest Rom experience I have had up to date.

Yes in theory it is a backup of everything, data, apps installed, boot, system, literally the entire phone is backed up. Is it a failsafe though? I would rather say not. On some phones we can restore a clockwork recovery and have no issues, but since I've had my epic and switched around with different Roms, I've noticed that restore dosen't work quite as it should, probably because Roms are so much different, and you run into FC's, boot loops, and other issues... Restoring peices in advanced restore works well but a complete restore almost always has bugs.
True statement though that even if you screw up and get a boot loop, or constant force closes/phone restarts, as long as you can get back into clockwork your phone is not screwed. You were right on that one. So no worries if you wanna test and play.

You have the idea right. You really don't even need to back all your apps up with titanium anymore these days, though, it too is plagued with FC's and problems. If you are using clockwork recovery, and you have made a backup already... all you have to do when installing a NEW rom is first wipe-fest, then let it boot once, then restart, go to clockwork, go to Advanced Restore, and ONLY restore the DATA part. (Reason for this is if you restore Boot, System, etc it will try to restore the Rom you just installed... Data is where all your apps/settings are at) This will do exactly the same thing as titanium backup will do, only with less bugs and alot easier.
Cool... thanks for the great response.
It's too bad there isn't an iron-clad, 100% reliable means to take a snapshot of the phone that can be restored reliably.
On WM it was simply a matter of using one of the various backup utilities (I used SPB Backup 2) to make an image of the system. No matter what I did to the phone, I could always wipe it back to factory clean, then restore from backup and have my phone back exactly as it was, with no issues.
I'm trying a CW backup, factory reset, restore cycle right now to see what happens. I'll report back on my experience.
EDIT: Okay, one deviation from the WM experience: The factory reset did NOT reset the kernel -- MixUp is still showing as the running kernel. Is Odin the only way to get the factory kernel back?​No matter what, I'm on my way after that to the Syndicate ROM!
EDIT: Okay, the CW restore seems to have restored everything back to the way it was, without problems after some brief playing around. No FCs (so far). On to wiping again, installing Syndicate Standard, then restoring data from CW as recommended here.​

Alright I took the plunge and it seemed to work well. Some things that I noticed was that on first boot (before I did the restore), all of the preinstalled apps showed up (for instance, wireless tether, wired tether, launcher pro, etc...). Since I did a restore of the data, all of MY apps are there, but some of the apps that were preinstalled disappeared. Not all of them, though. For example, Launcher Pro and Wired and wireless tether disappeared, but Car Home is still there.
Another thing to note is that my widgets on the home screen don't seem to function correctly at first. I had to remove them and readd them to the home screen for them to work.
Other than that, everything is as it should be.

Hmmm... okay. So just to provide a different datapoint, I'll go the Titanium route to get my own apps and settings back, and report. I'm guessing CW wiped the DATA partition before the restore, wiping out the pre-installed stuff from the ROM.

Ok, since yesterday, I tried both ways. I did a wipe back to the default Syndicate Rom and installed Titanium Backup. While restoring, I noticed that not all apps would restore (seemed to be ones that were in the stock ROM so it's understandable). I did a restore of apps + data. Now, I had most of my apps back, however, I noticed that some of the data was missing. For me, most importantly was the SMS Messages. I also wanted to note that doing an application by application restore of the backup was very time consuming! I had to basically reinstall every app (and then Titanium restored the data)
Nandroid doesnt seem to touch the kernel on our phones ether I noticed. I had a problem yesterday after I flashed a new rom and when I went to do a restore through nandroid I got a bootloop. Once I reflashed the kernel it fixed the bootlooping problem. I have noticed this in other instances to with kernels not being backed up since I did one after I rooted my phone so I would have a stock image.
Thanks guys on your experience and feedback on the backup thing that I'm wondering what to do after stock root.

This is what I have been told in the past- a nandroid restore does not replace the kernel

[Q] Endless reboot / cant get into Xrecovery

Hey guys.
Big problem here.
So I decided to update my phone with Free X10 Froyo 2.2.1 Beta 4
Installed it. worked. hotfix worked fine too.
After that I installed X.HC for beta 4. Worked fine too.
So I wanted to recover my data i backup with xrecovery before installing.
After that I'm stuck with an endless rebooting process. I boots, crashes, boots again, crashes and so on.
While I was writing this I finally got into xrecovery, but it took me 30 times to get there.
So my question is... is there any way to restore my data? Do I have to recover the cache to? I just tried to recover the data part of the back up.
Thx!
Do not dare to restore data if you are changing android versions.
Sent from my X10i using XDA App
Use titanium backup for backup and restore apps and data, not xRecovery when updating/downgrading between Android versions.
Ahh okay. So I wont get my data back but I will use this the next time.
Thx
You can use your back up to restore your data, but make the full restore, not just data.
I have the same problem as mentioned above, just that I cant get into xRecovery and dont know what I should do. I tried a few methods but nothing worked so far.
If someone might know any sollution answer me in this thread: http://forum.xda-developers.com/showthread.php?p=14532797#post14532797

I think.. flash a reset kernel.. so it will allow to boot (and skill the uv settings as well) and try again whtvr you were working on
the link to reset kernel is in franco's post...
Wont work
tried that 3 times
My guess is that some of your files are corrupted due to too much undervolts.
What I would do is first make a Nandroid backup from the recovery. Do a full wipe and re-install your ROM. Then you can use titanium backup or other apps that can restore apps+data from a nandroid backup.

This is basically your only choice. It's happened to me a few times.

for the first time this just randomly started happening to me yesterday also... it just rebooted and then was stuck at the animated neon fish PA screen... after restarting it just sat at the android is upgrading, starting apps screen after running through the apps.
when you say "full wipe", which wipe option(s) is that from within TWRP? i've tried cache/dalvik cache, and system, and then reinstalled PA 3.60 (jun 11), but the same thing is happening.

apps crashing in my backup (kitkat) after upgrade to Cyanogenmod 12 (lollipop)

Hi guys, so basically I made a backup of my STOCK rom and then I installed CYANOGEN mod 12 on the phone... Realizing I totally forgot about my contacts I then backed it up and "restored" my old backup of the stock rom which is kitkat. to find that EVERYTHING "stops working" so I cant get to my contacts.
Now heres where I believe I went wrong. I used philz touchwiz and upon my process to flash the phone I did the system/factory reset option or something like that and it asks if you'd like to wipe the phone to install a new rom. I selected yes so I thought that I was good to go and did not go further into the other stuff... I flashed cyanogen mod on the phone and then it said it was "upgrading my apps" ok well thats fine, and it ran great and no issues.... So going back to my STOCK backup after that, all the apps just crash, which I assume is due to still having the old apps which are "upgraded" to lollipop but the apps of course crash on "kitkat"
So, I've read that in a backup it saves all your apps and stuff.. It should return your phone back to exactly where it was when you made the backup. so why is it i'm having the app issues? I guess I need to delete them right?
So what is the options i need to do to get rid of the apps and do a proper phone wiping prior to a backup so that when I load my kitkat backup that It runs fine as it should? Wipe cache? dalvik? /data?, etc etc.... will it erase the main phones memory as a hole or no?
let me know how to correct this, I greatly appreciate it. I've tried googling to no prevail so far.
If I'm understanding correctly, you're trying to restore your KitKat apps onto cm12.
If that is the case, it will keep force closing apps. When upgrading and moving from touchwiz based Roms to AOSP based Roms you can't just restore from backups, the environment is different.
So to carry your contacts, I suggest recreating the same KitKat environment by clean installing whatever ROM you had, let google play store install the apps, then restore your app data only using philz advanced restore option (make sure all other options besides app data or data are unchecked)
Once all are restored, make a backup of your contacts and SMS using call log back up and SMS backup apps from playstore.
Back up any app progress using adb like
#adb -backup -f appname.ab -obb -noapk com.android....
And then do a clean cm12 install, let play store install all apps and start restoring call log, SMS, and your app data.
This takes a while, but it is worth it!
