sudden bootloop after normal usage - Zenfone 2 Laser Q&A, Help & Troubleshooting

OS is LineageOS 14 (7.1)
With latest TWR
Been using my ZE551KL normally without installing anything new for the past 10 days. Today I rebooted it hoping to fix a weak phone signal but got a bootloop.
Tried wiping dalvic and cache via TWR without luck.
Tried restoring system+boot+data from a 1 month old backup image. No dice...
Tried restoring another TWRP backup image from when I had CM on, also didn't work.
tried wiping everything [dalvic/system/data/internal/cache] and flashed a fresh Lineage ROM then gapps for a brand new system.... no luck... Same bootloop.
Still get bootlooped whenever the OS animation starts, whether it's Lineage's animation or CM's. Sometimes it bootloops before the animation, just before the animation starts.
Do you think I should restore an ASDF image from my brother's phone which is same model and OS?
If anyone got an idea on how to solve this, please let me know. I'm all ears.
Thanks

The last app you used/install might have corrupted something. Make sure you always check the permission an app uses, ESPECIALLY if you're granting it superSU permission. That's some dangerous stuffs. Two ways of unbricking:
1. Reflash your custom rom.
2. Reflash stock firmware.

Let me add another way. If you backed up via TWRP, then restore it. That's another fix

Stuck at boot screen after JB install help!

Hi guys,
After an attempt to install the new EOS JB rom, I got stuck at the loading screen and would not go further. I then tried to recover my backup rom and that still gets stuck at the boot screen. Can anyone point me in the right direction? I did some google search and I tried alot of methods. I am getting scared that I could brick my device and I need some guidance before I go any further. Please help!
The backup doesn't work because u need to flash the kernel,
In order to do that, Just flash your previous rom or if u know which kernel u had, flash the kernel
My TF101 will no longer boot. I was running the CM10 preview build, but I was having some random reboots and other issues, so I decided to flash CM9 this weekend. Like a good boy, I backed up apps with Titanium Backup and did a full backup in CWM (Roach).
I flashed the the ROM and GAPPS and was able to boot no problem. I used Titanium to restore my apps. I rebooted after the restore and was stuck on the boot animation for close to 20 min. before I forced a shutdown and went back into CWM. First, I tried a factory reset and tried to reboot, with the same effect, then I restored my CWM backup and had the same boot problem, then I tried a earlier CWM backup that also had the same effect.
I'm starting to worry about battery levels now. I started on a full charge, but it's been running a lot. I'm also out of ideas barring NVFlash, which I don't want to do unless I have to.
Is this the same issue?

Took the advice and tried flashing a ROM that thankfully I still had on my SDCard that was CM10 based and that let me restore my backup.

ICS based ROMs can't boot up with JB kernels and CWM backups don't contain the kernel as far as I am aware. If you want to go back to CM9, you would have to flash the appropriate kernel. Once you put CM10 on your device, it would contain a JB kernel, hence why it couldn't restore your nandroid.

I never flashed the kernel, I have been on stock. The EOS team says that JB will run with stock kernel so I did not change anything. How would I flash the kernel if I am stuck at boot screen? And which kernel should I get
Why can't you go back to CWM recovery, (holding down power and volume down button until you see some text then volume up?
For any ROM fresh install, you need to wipe data (factory reset), davik cache, cache, all in CWM Recovery before installing the ROM and kernel (optional).

I tried but apparently my CWM version does not work well with tf 101. I found a solution by flashing another CWM. Here is guide for those with the same problem.

Your link is broken and i would love to try it.
I have the same problem.....
I rooted, installed Rom Manager to get CWM Recovery installed and then flashed the new CyanogenMod 10 - B1 ♦ K.A.T. As soon as I restarted, after it appeared that the flash went fine, it hung at the boot screen - not frozen just wont go any further.
I tried rebooting by holding the power button, I tried re-flashing both the CY 10 and the original Rom and tried "restoring" my backed up rom.
I have tried recovering through Easy Flasher but I don't think my PC is seeing the transformer properly.
I have ADB drivers installed but because the TF dose not boot properly it dose not seem to get there.
I have let the battery drain as some report a resolve when they get it to power down all the way but as soon as I plug it in and power it up it goes back to the boot screen and stays there.
Please help as I cant afford to lose this pad (yes I knew the risks).

Stuck at Google logo on CM13 flash

I saw another user or two had the same issue as I am having here. I've tried dirty flashing, factory reset, system wipe, and a full reflash of Googles stock images. Still when I try and boot into CM13, I get stuck at the Google logo. Does anyone have any tips or tricks on how you booted the latest nightly?
I know it's still very early in the development process, so bugs are to be expected, but I can't even boot the rom.
i am in the same issue... i was on factory, flashed cm13, never fully booted, so wasnt able to get to turn usb debugging on.... now im stuck... cannot get it to boot no matter what...
cannot flash a factory image as adb does not get detected because i cannot get into android to turn it on...
HELP!!
I never could boot either

What all did you restore in the nandroid backup? Just System, or everything?

cant flash to any other ROM.. aside from CM13

Was using an CM13 unofficial build for months... then i decided i needed SPen and Heartbeat sensor
so i was hoping to try Erobots rom ( did full wipe ) , after successfull install... got boot loop... just keeps restarting on the Note 4 Logo
so i tried reflashstock rom(s) with both odin and kies 3 , after every flash , i always get the installing system update... erasing... and then boot loops
i though i got a perma soft brick.. till i tried using Cm13 again.... and it works ??
so what's causing this ? me not being able to use TouchWiz based roms ? both stock at custom
up
Try going to Recovery via the 3-button combo. Then wipe cache and data/factory reset.
If it didn't help, flash the official stock rom via odin. Then do the wipe cache/factory reset again in Recovery after flashing the stock rom.
yup tried those... i always ended up.. installing system update... then erasing... then boot loops
I have the exact same issue, I was stupid enough to not backup my system with TWRP when I had first rooted the device, so I cant just 'restore' my backup. I would like to use another rom but cannot due to this issue.

I've had something similar when I tried CM. It uses a not so generic recovery.
Try to flash a different recover with Odin - TWRP for example.

Softbrick Nexus 6P

Please help me. I'm using a Google Nexus 6P. I'm in a softbrick state (bootloop). At first, i taught a simple flash of stock factory image from google with help. But nothing helped. I tried everyhting from the internet asked me to do. I used adb, fastboot, nexus toolkit, but nothing helps. The phone keep on bootlooping. I can go to bootloader and recovery. The bootloop starts when i was flashing a nandroid backup (PureNexus Rom) from a BenzoRom. When i finished flashing the nandroid backup, the bootloop starts. I even did a factory reset, wipe everything, flash a fully stock rom (7.0.0), but the phone won't start..please help me XDA..i really need your help!
Are the android versions of Benzo and PureNexus the same?

Same thing happened to a lot of us. Some were able to recover and some were not, unfortunate I couldn't no matter what I tried. And believe me I tried everything possible. Fastboot , toolkits no go , as for me I couldn't even access recovery. So I did the next best thing, as I was able to flash factory images and lock bootloader I had to rma the device. Waiting on the new one now.

I was able to flash all factory images manually, I was able to use a toolkit which I normally won't use to download all the images fine. Just that when it came to booting up or even accessing recovery it was a no go. Everything flashed fine via fastboot or toolkit.
I actually did it! oh my god i actually did it! i got out from the freaking bootloop! and trust me i tried EVERYHTING else. Only this method, for me at least, helped. I will described exactly what i did.
1. You need a nandroid backup. Any nandroid backup for your phone is good i think. You NEED to know what version of nandroid backup you are having, and what version of ROM.
2. Wiped, erased everything on my phone.
3. Reverted my phone to stock version of the nandroid. (Google Factory) (For me i reverted to MTC20F full stock because my nandroid backup was on PureNexus MTC20F, used flash all.bat)
4. Tried booting to system but failed, still bootlooped.
5. Flashed TWRP, for me, TWRP 3.0.2.0 works. My suggestion, don't go above this version of TWRP, lots of problems!
5. Flashed the custom ROM the nandroid you had (for me, the nandroid backup was PureNexus MTC20F 6.0.1, so i flashed the PureNexus ROM running MTC20F vendor)
6. I tried rebooting to system, but not to avail.
7. I restored the nandroid backup i had earlier.
8. Progress, the boot animation appeared. Before, only Google logo poped out and then it restarts again.
9. Flash back to full stock MTC20F. (flash all.bat without wiping anything)
10. The phone fully boots!

Phone won't boot into OS and only boots to TWRP

Hey guys, I decided to try and install a custom ROM on my phone, but after trying a few things, my phone now won't boot into anything but TWRP. Here's exactly what I did in chronological order:
1. Flashed official TWRP
2. Tried to install Pixel Experience by *only* flashing the .zip - it was extremely buggy, laggy, and just straight-up unusable
3. Used the "format" option from within TWRP > Wipe
4. Tried installing Pixel Experience (had to use it on an external USB) - appeared to install fine but it won't boot into it, just reboots into TWRP
5. Tried Pixel Experience "Plus", crDroid, Lineage OS, and stock ROM, all had the same result as PE in step 4
6. Tried using blu_spark TWRP, same result as step 4
I have absolutely no idea what to do or how to fix this. Can somebody help me? Thanks!

2 things.
First flash the latest FW that is needed for the custom ROM as per their thread.
Then format data and flash the ROM you need.
Use CodeowrkX Forced Encryption recovery.
Let me know if it works..

You didnt FORMAT data and reboot. Do that and then post reboot, do another format/wipe from stock recovery. You will loose data, I reiterate.

For the param issue, seems your driver is causing issues, or else the unbrick rom file is broken/corrupt.
