Lineage stuck on boot loop on startup - Moto G4 Plus Questions & Answers

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

Stuck on "Starting apps." on Quarx cm-10-20130527

After a battery empty, I restarted my Defy+. But now it got stuck on "Starting apps." at the end of the boot.
I have to wipe data to make my phone ending the boot.
If I restore data which I previously backup in recovery mode, I'm still stucked with "Starting apps."
How can I debug the settings or data that avoid that? I really want to restore my data.

Are you using the new Teamwin recvoery to flash?
Ive had the same issue ( and many more besides that) for me, to fix the problem i did this:
Go back to recovery (Teamwin) and wipe everything
re-boot, go back to recovery (team win) and flash an older rom with clock work mod recovery, and let it boot.
re- start the phone and then go back to recovery ( clockwork mod) and flash the newer CM10 rom from clcokwork mod (First wipe everything /data/dalvik/cache/factory re-set)

Thanx,
Yes Teamwin delivered with cm-10-20130527.
What I done without success:
*Flash older ROM and restore more older data with CWM
*Push with adb unzipped
I should have flashed 10 to 20 times changing some steps each time. Each time I done wipe cache, dalvik and sometimes a data format and a wipe system.
I abandoned the idea to restore my data. Have to reenter all settings manually (find and enter account settings for CSip or some solooong preshared key for Vpncilla and so on).
Then what is positive: I format my data partition to ext4. I learnt a lot from very fragmented information for all those steps. I have a fresh new install.

You can use Nandroid Manager to use ur data while the phone is booted, so install it, it will find ur backup, and the u can do a restore of ur apps, with data.

"Nandroid Manager currently supports nandroid backups created by TWRP and Clockworkmod (v5.xx and v6.xx) based recoveries! ".

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!!

Not able to boot any ROM

Hi,
Coming from PureNexus, I wanted to give CM13 a try. Made a nandroid backup so none of my data is lost, and put that backup on pc. I installed CM13 which went fine. It stopped at the CM booting animation and did not go further, so I cleanflashed Purenexus to restore my backup later on. Now PureNexus won't boot either. I'm out of ideas to try, and I want to get my phone back up and running ASAP.
Can anyone help me with this issue?

When you clean flashed, did you also wipe system? If you did and you're still hung at boot, your best bet would be to flash the factory images via fastboot and start fresh.

Are you wiping properly (system, data, cache, dalvik cache) before installing a ROM? Are you making sure you flash the appropriate vendor image after flashing the ROM? When you made your backup which options did you check? And which options are you restoring?

When I try to wipe, it's only wiping cache for some reason. My backup consists of everything except cache.

What do you mean it's only wiping cache? Explain to me how you're doing the wipe. Also, when creating a backup (and restoring it) you should only be selecting system, data, boot, and vendor.
PS. You didn't answer my question about whether you're flashing the vendor after flashing the ROM. If you want help you need to answer the questions that are asked.

I'll keep that in mind. When I boot up TRWP, I wiped system, dalvik, data, internal storage and cache. After that I pushed CM13 through adb. That's where the problems started.
EDIT: I flashed the most recent vendor after I flashed the ROM.

Ok, you definitely don't need to wipe internal storage before flashing so don't worry about that part. Only system, data, cache, and dalvik cache. You said before only cache was being wiped, can you please elaborate on that?
Are you sure the ROM zip didn't become corrupt during the download? Did you check the MD5 to ensure that it didn't? That could be what's causing your problems. Also, what gapps are you flashing?
If you want to go back to Pure Nexus just to get your phone working you can just restore that backup, just make sure you only restore system, data, boot, and vendor.

It won't wipe anything other than cache, no matter what I'm trying to do. Now when I'm trying to push a ROM through adb, I can install it but it won't boot.

I found your guide by googling, thanks for making that! Flashing the factory image worked, and I succesfully restored my backup. The only problem left is that it won't accept my pattern lock. I have used the same one for years across multiple android devices, so I'm absolutely sure I have the right pattern. Any way to bypass this?

You need to remove all security before making a backup because the security information is encrypted and doesn't get backed up or restored properly. You can delete some files using TWRP (see section 3 of my guide) in order to remove the security so you can get into Android. This will cause problems with Smart Lock though.

Failed installing Lineage 14.1, wiped system, now restoring stock won't boot

Attempt 1 to install Lineage
Tried installing the Lineage 14.1, it kept doing a blank-but-illuminated screen, then turned off and back on, resulting in a boot loop.
We tried a couple of things - first the more conservative wiping of just data, dalvik and cache.
This did the boot loop described above. I then restored the stock backup and all was well.
Attempt 2 to install Lineage
The second time we wiped the system partition in addition to the above. Same bootloop.
Went to restore the backup of stock again, but now it's getting stuck at "I'm not a phone I'm a comprehensive yada yada" screen. It never progresses past this.
Attempts to get Stock Restore working
We've tried restoring just the system, data and dalvik
We've also tried System Image in addition to these.
No joy.
We don't have a laptop or other device to hand for a few days so we have just what's on the phone - the Lineage 14.1 zip, the stock backup and TWRP.
Any ideas how we can get back to a working phone with either OS?
What type of LePro3 do you have?
X720,X722,X727?
It's the X722

It's the X722

The X722 model is not supported by Lineage.
I think that you have a problem. Hope anyone can help you to go back to stock successfully.
When doing the stock restore, we didn't restore the boot image.
Is that something worth trying?

Axon 7 randomly stopped booting

Hi there, I have an Axon 7 with LineageOS that was working like a charm until I rebooted it today. It was in the normal lineage OS boot animation with the blue circle moving from right to left, except it never stopped. Now after trying a few more times, it just keeps playing the animation except the phone will vibrate slightly every several seconds. The phone is encrypted but that hasn't been a problem. When I reboot to TWRP, it says Unable to mount storage.
I tried wiping Cache and Dalvik / ART Cache, but this didn't help. Finally, I do have a backup from 7-20-2017 but I'd rather not have to go back to that...
Any recommendations?

So you can't see the internal storage from TWRP? I'm guessing encryption actually plays a part here. Formatting data is probably the best course of action, though you should flash magisk or superSu if you do, to get rid of encryption. But you obviously lose everything that's on the internal storage.
Maybe make a system and boot backup and clean flash Lineage. Like, wipe system and caches, then flash the bootloader, modem, LOS and whatever else you flash

Is it easier to just use the backup I have currently? If so, what are the steps necessary for that (sorry for newb questions, haven't messed with it in a while)
EDIT: Also, TWRP claims decryption is successful when it is loading up.

Again. Can you see the internal storage?
Don't restore the backup. Your problem is basically either on /system (clean flash of the ROM will do) or on /data (complete format of data is needed). So try the non destructive one first

I don't see any storage folder. So if I want to install the latest LOS and frankly just start from scratch, can I follow the guide here https://wiki.lineageos.org/devices/axon7/install#installing-lineageos-from-recovery starting from "Installing LineageOS from recovery"? Will I still need to install something to wipe the encryption?

What? No... That's for normal phones. How did you manage to install LOS without knowing that you need the univ. bootloader and modem?
So, you can't access the internal storage via the file manager on TWRP i'm guessing.
Wipe - Format data, after that flash the Universal bootloader, modem, LOS, Magisk, GApps. Magisk takes care of dm-verity and disables encryption. Don't try to uninstall it though or your internal storage will get encrypted as soon as you do. But if you want to change ROMs you can just fpash it before booting and it won't ger encrypted.
