[ZenFone 2 Q&A, Help & Troubleshooting] ryankabir:
DUDEE

that's not a problem.. THAT's like 20 different problems... I bricked the living crap out of my zen the day I bought it (because me = smartypants did not know that the MM boot unlocker is nonexistent so I just tried to root and update from my head using older techniques) and... the XTS tool thingy fixed it..

Don't get me wrong, i want to help but this is the problem that I feel little frustrated with..

Zenfone2 doesn't boot most of the times (either looping after the white ASUS screen) or rebooting during loading of CM13. ## (but it boots sometimes and goes into TWRP, so you have an easy fix to just revert to stock lollipop... why haven't you done that? You sound like you know what most of this stuff does...

Charging problem, so I unplugged the battery from the back and put it back. This seemed to solve the charging problem. But problems above still persist. Thinking it may have corrupted some memory.

## how do you connect this battery issue to your occasional bootloop? Check hardware or firmware and definitely use different threads.. there's no way these are all part of the "same problem"...

When in TWRP, after pressing randomly some buttons and go back to mainscreen, the touchscreen stops responding too and reboots

## Same answer as above - this is unrelated to #2 and unrelated to #1 - is your TWRP the correct one? I mean... did you just maybe flash TWRP version 4000 Modified Alpha for Google Glass??? LOL

When in CM13, after letting the phone sleep for a bit (2 mins roughly) - it doesn't wake up from power button. Have to press long and boot again.

## Is D2W there? "DoubleTap2Wake" ? Are you sure you have a good touch? (this maybe 20% sounds related to your TWRP touch going crazy..)

Cannot get XFSTK to detect the device (Windows says: USB device not recognized or something like that).

## There's this awesome invention called DRIVERS... and we're lucky in this case (cuz I bricked an hour after I bought it) because Intel PC + Intel Phone = Yay... There is even.... a very specific "INTEL ASUS WINDOWS DRIVER" file... from the INTEL AND ASUS WEBSITE... or maybe your USB CABLE is f**? My point is... another unrelated issue where it sounds like you've not even tried it properly before complaining.. I like helping people. I don't like when people refuse to try or they skip the actual study-notes to do it... I used the EXACT same guide to unbrick and it worked in 2 mins... I'm on a 2007 Laptop which overheats if I use 4 tabs... how am I able to follow the exact same guide on a brand new "FULLY BRICKED" phone... it literally would vibrate after trying power button for 5 mins and be stuck in a "blank black screen" for hours and hours... No twrp no nothing.. and I did it - why didn't you? Same guide man...

When the USB cable is inserted into the device, it sometimes looks like the power+vol up combination doesn't do anything when booting (either the screen stays black or it tries to boot into CM13 and fail.)

## Try again. Sometimes people accidentally hit power to early.. or whatever.. It's not a MK2 Fatality.. don't force yourself to get it exact.. Let the menu pop up... just wait a second and scroll up/down just to see if that works... then scroll to Boot-Recov and gently hit power+vUp.. should be fine.. otherwise just .. literally try 10 times.. it WILL work.

Since TWRP seems so unstable, I wanted to reflash everything using the Unbrick guide via PC

## Nope.. TWRP is like Bret Hart. It isn't unstable. Not for LP not MM not for N. Not for Stock Not for CM Not for AOSP. You *wanted* to do what you should have done right at the beginning but you didn't get that done properly (see below)

Essentially you have 8 different unrelated issues (and the biggest one is not reading guides, not trying hard enough and just thinking that people like me sit around and get paid for this)... and want ans in one place w/o just doing the simple thing of going back to everything stock...?? *it's just annoying cuz people who want to help will feel like.... others don't even try simply because we exist and have desire to help...* - I am not trying to offend you but I hope you get my pov.

Do This EXACTLY

#Buy a cable. Borrow a cable. Whatever you do be 1000000% sure the USB Cable is fine

#Install Intel Asus Android drivers from official EXE (google it... don't add new post for that link)

AND THEN

Follow the same Unbrick guide word for word *but* just pay close attention to these:-

IntelSeC Driver + device detected even if OFF (start>devman>showall>intelsec

In the official unbrick utility make sure you're on the second tab at the bottom

In settings check that your device flag is 0x08..... whatever instead of the default 0x000

Back in the *second tab at the bottom* (i don't remember exact name but it's in the guide) -- put the right files (mentioned in guide) in the right boxes.. (mentioned in guide) and remember you ONLY need the DVFWthingy... + TOKENthingy + IFWthingy

Plug the Zen in... hear the "da-dumm" sound... keep looking at the Unbrick tool.. and the moment you see Device Detected = 1 you hit install/start...

AFTER that is fully done *(and if you fail don't post just repeat from scratch)... I don't personally recommend Asus Flash tool it was acting dodgy for me but instead grab the RAW Stock... Rename it to zip.. open it and grab the img files and fastboot flash the fastboot droidboot.img + splashscreen splash.img + boot boot.img + recovery recovery.img

If you've followed all that from the guide and double checked what I've put up there.. you should be fine if you just fastboot reboot bootloader... and go into stock recovery... install zip/update and put your stock OS in there..

Done.

Just please take my advice and don't skim through guides, don't think you don't need to read something, don't click stuff without double checking every line from guide, print it out on PAPER if you need to.... but please don't post like this... and don't use different guides or you will be stuck (as your heading stated..)

Forget everything you knew. Close all other tabs and use this guide thoroughly for Reference:-
