[Q] Maybe in a bootloop? - ZenFone 2 Q&A, Help & Troubleshooting

Rooted my phone using Temporary CWM method, installed Titanium Backup and restored from my old phone. Selected All Apps and Data. Rebooted my phone and I assume that it is now stuck in a bootloop. It gets to the ASUS and Intel Inside screens, then I get a spinning circle forever (well, at least 3 minutes).
Where do I go from here? Reflash the ROM and start over and don't restore system data? Is there an easier/quicker way?
Thanks

Go to fastboot mode by holding the power and volume up button,connect USB cable be sure that you installedmusb and fastboot driver.go to folder of fastboot and hold shift key then right click open command window here and type:fastboot erase cache then enter fastboot reboot and voila..

Thanks for the reply, but that didn't do it.
I was able to execute the commands, but still no luck. I got into recovery to try and wipe from there, but got the dead android. I them held power up and tapped vol up to get into recovery. tried to wipe cache from there and the phone just sat there for 3-4 minutes with nothing. Now when I get into recovery, I get a flashing dead android, and the power/vol up trick doesn't work. I can still boot into fastboot.
Di I just need to reflash the stock image? Or is there something else I can do?

I had the same problem as yours and it took 3 hours before i figured it out and managed to run the phone normally.I downloaded all the files,drivers and latest prerooted system img. here in this forum.you can download it there and there is the instruction how to do it.
To Begin :
1. on Fastbootmode connect your device and on the flashtool folder hold shift key and right click and go to open command here,be sure that downloaded images are in the same folder.Recovery img.,Boot Img. and the big pre-rooted System img.
2. type fastboot devices then hit enter key - the device nos. should appear and you can start now to flash...
a. fastboot -w then hit enter this will erase the system
b.fastboot flash system system.img then hit enter key
c.fastboot erase userdata then hit enter key
d. fastboot erase cache then hit enter key
e. fastboot reboot then hit enter key..

THANK YOU!!!
Thank You, Thank You, 1000 times, Thank You.
I did everything you mentioned, with a few small exceptions
1. Make sure you have the lastest version of Fastboot
2. Instead of step b above, I did the following. Not sure if it was needed or not, but it worked for me
fastboot flash fastboot droidboot.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
3. At the end, after I did a Fastboot Reboot, I got the dreaded dead android again. I nearly cried. However, I rebooted again, and everything seemed to work. Note that on the first boot, it may take 2-3 minutes for the OS to come up.
4. All of the files and great insight can be found here: http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596

[Q] Wiped internal memory (recovery and ROMs can't mount)

I'm a dummy.
First off, I'm still S-On.
I was attempting to flash a GPe ROM using TWRP and figured I'd wipe my phone while I was waiting for ROM to download. I clicked 'Wipe' and after not very carefully choosing my option and typing 'yes' (bottom right button, the one that nukes everything) I found that I couldn't keep my Recovery partitions running because they couldn't mount to the internal storage. TWRP just flickers before finally rebooting into a loop and Philz runs for about 20 seconds while giving me errors that it can't open or mount to `cache/recovery/...` before rebooting into the loop.
I've tried formatting the directories in Philz in separate 20 second windows by hand and have managed to make my way through the list (/cache, /data, /system, etc) to no avail. The errors that Philz gives that it can't open or mount to `/cache/recovery/...` are gone, but there is still only 20 seconds that I'm able to use it before rebooting into a loop. I've tried booting into recoveries with `fastboot boot boot/recovery.img` but those only stay running as long as the flashed recoveries (BTW I've downloaded all the recoveries and ROMs I'm trying multiple times).
It seems like the only thing I have at my disposal right now is Fastboot; ADB works in the 20 second windows, but I haven't been able to find anything on how to fix this and can't do much by myself in 20 seconds; I've tried to use RebootRUU, but as far as I can tell that just brings me to a black screen with HTC and gives me access to Fastboot.
I have no idea what to attempt next, does anyone have any thoughts or pointers? Thank you.

Try flashing the stock recovery and then factory reset in bootloader then try custom recovery again.

That's OK. Press volume up and down a few times and select factory reset eventually. It takes a few tries and it will show up

Make sure you're in the bootloader go into fastboot and make sure the downloaded image is in the same folder as your fastboot.
fastboot flash recovery stockrecovery.img
fastboot erase cache
fastboot reboot-bootloader
Go into bootloader and then choose Factory Reset - let that finish running <<<Important!
Phone will go out and start bootlooping. Now power off and go back to bootloader mode:
Go into fastboot
fastboot flash recovery <custom recovery>.img
fastboot erase cache
fastboot reboot-bootloader
Now you can go into custom recovery and you should be good to go now.

That just means you have a stock recovery installed but no update to install, press volume up and the power button to enter the stock recovery when you see the red triangle.

Quick question, is it always best practice to always clear out your cache? is there any risk in clearing it?

Android bot error blinking on boot after wipe partition cache process

Model: Asus Zenfone 2 ZE551ML
After updating to latest version i decided to wipe partition cache while on the process it showed erasing android bot then restarted and hung on asus logo for nearly an hour so i decided there is some problem and force switched off then after switching on it shows the blinking android error bot.........im unable to enter neither recovery mode nor fastboot mode(when entering it shows for a some seconds waiting fastboot cmd bt then comes again to the normal boot screen)....
Its been nearly a week i went thru various post and tried most of the methods like entering recovery mode thru adb(as im unable to enter fastboot mode it shows in cmd waiting for device) and pressing both buttons same for stock recovery(it shows some lines saying in last line can't mount recovery)
SO CAN SOMEBODY THROW LIGHT ON WHAT EXACTLY NEEDS TO BE DONE TO RECOVER MY PHONE FROM THIS ERROR.... would be grateful and thanks in advance.
Feel like you for the same worries as I did.
Try to flash bootdroid.img / boot.img / recovery.img with fastboot commands and that should do the trick.
For recovery I renamed twrp.img to recovery.img to get twrp right away

maybe you have flashed wrong droidboot img for fastboot partition.. if you manage to enter fastboot mode, you may try to type
fastboot erase cache
but only if you able to enter fastboot..usually wiping cache from stock recovery may stuck but it can be cleared with that command.. but if you are unable to enter fastboot mode sorry then, hope that someone expert can help you..

Boot-Looped device. I'm willing to try anything at this point.

So before I get linked to a bunch of solutions, here's what I've tried so far as I do have fastboot access:
I've tried flashing the latest factory image from Google. Both manually from fastboot and with NRT, all to no avail. It shows the Google logo then reboots repeatedly. I've tried entering recovery to factory reset there after flashing, but the device won't get into recovery.
I've also tried this method, but I can't get the device to enter download mode. It shows that it's entering it for a moment when I plug it into my computer while holding volume up, but then reboots into the bootloop again.
There's one weird thing that should be noted that makes me think this is some weird software issue, and not a hardware failure. I let the device bootloop all night last night until the battery died. When I powered it on this morning it went all the way to the Android setup page where you select wifi, etc and go from there. However, when I plugged it in and kept going through setup, it rebooted and has been looping since. I've contacted Google and they're supposed to conference call me with LG to see what we can do. Do I have any options other than that? Thanks for any help.
From bootloader
fastboot erase cache
fastboot format cache
fastboot erase user
fastboot format user
BTW what exactly is happening when you say it doesn't enter recovery?

I choose reboot recovery from the fastboot menu and it just boot loops. It won't enter recovery.

what if you try
fastboot boot twrp.img
I've bootlooped so many times I don't know where to start.
So you flashed the factory IMG from your bootloader correct.
Fastboot -w will wipe without wiping system.
Then reflash your whole system. I would redownload from the Google site through Skipsoft...the easiest way. When it asks to keep or flash new recovery you want to flash the stock recovery.
http://forum.xda-developers.com/nex...olkit-skipsoft-android-toolkit-nexus-t3230444
You'll have to reroot afterwards which you can also do through skipsoft.
Profit... Thank me if I helped.
It's a Hardware issue. Installing system again will not fix it. Send it to LG for a repair. My phone had the same issue.

URGENT TWRP switch back to stock recovery after reboot

I used this https://dl.twrp.me/oneplus3/twrp-3.0.2-0-oneplus3.img.html recovery to flash but after reboot to system and then to recovery it shows the stock recovery. Any help ?
That's quite normal. If you flash a stock rom without reinstalling twrp before rebooting system, you will lose twrp because stock rom will install stock recovery too . So, you have to install TWRP from adb by Fastboot again.

Honestly its not that urgent to be honest before you flashed the stock rom you should of read up on what was going to happen. Being knowledgeable about what you are doing is your biggest asset. Also its not that big of a deal reflash TWRP as mentioned and going forward do some reading before making moves
Also make sure the right stuff is checked off in your settings so that the stock recovery does not come back
if u can still boot into ur OS just download flashify and flash twrp via flashify, u can download twrp via flashify too
this is normal it happens from time to time

did you follow these steps or did you just reboot directly into the OS
2. Flashing TWRP
Turn the phone off. Then boot it into fastboot mode by holding volume up + power.
Rename the recovery file that you downloaded above to recovery.img. *Make sure that you rename it to recovery.img NOT recovery.img.img* ,Make sure that this file is placed on the desktop.
Open a new command prompt on desktop and run the following commands:
Code:
fastboot flash recovery recovery.img
Once the flash has completed, Don't use the "Fastboot Reboot" Command Instead Unplug Your phone then Manually boot it into recovery by keeping Power + Volume Down button pressed.
In TWRP, select Reboot and then select System. Now your phone will boot into System and you have cleared Steps 2/3 . Grats.

Yes I did. Don't know why it didn't work first time. Everything fine after factory resetting again

In need of some backup

Problem:
Unlocked phone is seemingly stuck in bootloop. Need guidance fixing it.
Explanation:
Hey guys,
I bought a used Nokia 6 (2018) and want to install a custom ROM on it. Last year, I used the paid service to have it unlocked - worked like a charm! So thanks again for that! After reading up on the topic, I set up drivers, adb and fastboot on my PC (Win10). I used
fastboot erase cache
fastboot erase userdata
fastboot erase boot
fastboot erase system​to prepare the phone and then
fastboot boot twrp-3.3.1-1-PL2.img​to get into TWRP. Next is where I ****ed up I think.
I followed a guide and moved twrp-installer-3.3.1-0-PL2.zip on to my SD card. In TWRP, I chose "install" and then picked said installer. After that, I chose the option to reboot.
That must have been the wrong thing to do, because now the phone only boots into download mode. When I hold the power button it does not shut down, but instead instantly reboots into download mode.
When I type
fastboot devices​I still get
PL2GAR9811701240 fastboot​and Windows plays the "connect" sound, when I plug it in. Yet all fastboot commands (boot, flash, reboot) now return
FAILED (Write to device failed (Unknown error))​What can I do at this point? Can I somehow revert to stock? How is that done? Can I use this guide and the linked stock ROM?
If you'd like more information, just ask away. I'm glad for any guidance at this point, so thanks in advance for your help!
