How to Enter "Recovery Mode" on Asus Zenfone 2
Turn Off your Zenfone 2
Hold Power button + Volume up
When the phone is vibrating release the Power button
Then the Display change like this
You can select "Normal Boot" or "Recovery Mode" by pressing Volume Up/Down, to enter Recovery choose "Recovery Mode"
Then you will see sleep Android Robot, Press Power button and Volume up, after one second release the Volume up
You will see Asus Zenfone 2 Recovery Mode
after that follow these steps and BOOM BAM !! I DID IT
Download and Install ADB and drivers on your PC.
Download the latest Stock ROM from the Asus website by visiting the following links. If your device got bricked after a recent OTA software update, wait a few days while Asus uploads the latest Stock ROM. On the page below, select Android as the OS and then expand the Firmware section. For non WW devices, please check your regional Asus website for the download details.
Zenfone ZE551ML Stock ROM
Zenfone ZE550ML Stock ROM
Copy the downloaded Stock ROM to the folder where you installed ADB (Generally C://adb)
In power off state, press and hold the Volume Up key and then press and hold the Power Key till the phone vibrates. Release the power key at vibration, but keep pressing the Volume Up key. Wait for the phone to boot into fastboot mode.
In the fastboot mode, keep pressing the Volume Down key till you see Recovery Mode. Press Power Key to select it.
In recovery mode, select Apply update from ADB.
Connect your phone to the PC and open the ADB folder. Right click while holding down the shift key and choose Open command window here.
Pass the following command in ADB. Replace file.zip with the name of Stock ROM zip (eg: UL-Z00A-WW-2.19.40.22-user.zip) downloaded in step 2.
adb sideload file.zip
Wait for the process to complete as it will take a couple of minutes.
Reboot the phone when it is all done and hopefully your Zenfone 2 will be boot up fine, alive and working again.

Does the zenfone2 have a fastboot mode to flash the firmware manually because flashing Ota updates bricks if you never unrooted you phone. So you should just flash the firmware you were already on then unroot then flash the Ota update

adb is not able to detect my phone. is there any other way to flash the phone ?
and i am just a bit curious to know if its possible to directly flash the phone with CM12.1 without having to go through all those steps (installing the older version and unrooting and installing the OTA) ?

and how can i flash the original rom when adb doesn't detect my phone ??

The command you have used is not a flash, it is only a boot into the twrp recovery, twrp will work than,
but nothing is flashed and so after reboot ther is no twrp.
Shut down phone, connect it to your pc, put it on, when adp is detected enter : adb reboot bootloader
than flash/boot into twrp and reflash
Have you tried a fac reset/wipe?
For Hardware Reset:
turn off the device
press and hold the power and the vol- key
release power key when the lg logo is displayed (holding the vol - key)
immediately press power key (you should still press the Vol - button)
when in the factory reset menu folloe the onscreen instrucions to wipe it

G4 stuck on boot loop (maybe wrong SuperSu, no download mode)

Hello everyone i tryed to search similar issues in the forum but i only found this thread without solution: http://forum.xda-developers.com/g4/help/h815-stuck-bootloop-download-mode-t3235362
My G4 stucks on boot loop and i cannot reach bootloader mode or recovery.
I updated to M then i decided to unlock the bootloader.
Then I try to install twrp. Via fastboot flash command twrp doesn't seem to get installed. So i try to boot in twrp and then install the img to the recovery partition. All seemed to go fine. When i try to reboot to recovery twrp ask me to root the device. Why not? I leave twrp installs superSu (I think this was my mistake). Now I've a continuous bootloop, even if I simply plug it to the charger. Vol down + Power buttons neither vol up + power doesn't work.
Sorry for bad english

Yep.. You shouldn't have selected the built in version..
Copy an updated SuperSU.zip file onto a spare SD Card and slot it into the Phone.
Reboot into TWRP and install the new SuperSU.zip from the SDCard..

Are you able to boot TWRP? Of yes, take Hostilians advice.
Are you unable to boot TWRP? Enter download mode ( unplug device-> hold down Volume + -> plug device) and install a fresh OS using LGUP.

Hi
I have same situation. After SuperSu zip installation my G4 stuck on boot loop. Can somebody explain a little bit this procedure? I don't know how install a fresh OS and don't know what is a LGUP.
I found another link over Internet but...I'm not sure: rootmygalaxy.net/unbrick-lg-g4-with-lg-flash-tool
I don't have any way to enter into TWRP because as I say G4 is stucked and adb command don't work.
Any help appreciated

Follow this instructions here... although it doesn't tell you how to use it with your device in download mode! Anyways... is very easy to do it.
First install LGUP_8994_DLL_Ver_0_0_3_23 them LGUP. Plug in your device (you will notice that it doesn`t recognize your device, no worries) Unplug device, shut down, hold Volume + and plug device. It will enter download mode. Now go to LGUP click upgrade and choose your .kdz. Easy.
Cheers!

Hi
I didn't have to do it exactly this way. My phone was stucked in boot loader (black screen lg logo) and simply connected by usb to my windows. LGUP detected without extra actions and then I refurbished it with a kdz file.
Hope it helps someone
Thanks!

First of all you need to know your device's bootloder is locked or unlocked for that type *#*#7378423#*#* in dial pad then go to service info >configuration and check for bootloder unlock allow
If it say yes then it's unlock
If it says no then it is locked
Do as follow for unlocking the bootloder
You need your device's IMEI number and a password for unlocking your bootloder
You can get your password by following link
Do step by step
http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
1)switch off your device and open flashtool(download from following link)
2)select the unlock bootloder and connect your phone with flash mode by keep pressing vol. Down button and connect the cable LED light will turn green and then it will off
3)enter Your device's IMEI number and the password you got from Sony
4)click on unlock
Now your bootloder is unlocked so now can install custom recovery like XZdualrecovery,TWRP,CWM (unfortunately CWM is not supported in 5.1.1)
For installation of recovery you need to download full Rom from Xperifrim or other source and convert it into Ftf file
You need 1) kernel which have recovery pre-installed like doomlord's kernal for D5303 device for Android 4.3
2)For recovery which work with it just download latest version of XZdualrecovery for T2 ultra from thread and download the Release file (there are 2 file which are located there one is release and second is installer)
Download it on phone and move it on place whare you can find it easily
1) Now switch off your phone open flashtool
2) select flash sign and select fastboot mode
3) Now connect your phone with computer in fastboot mode by keep pressing vol.up button and connect the cable and LED light will turn blue
4)select doomlord's kernel file for flashing (it'll be on img format so select img from file type)
And flash it
5)Now disconnect your phone and boot it. When Sony logo appear and then keep pressing vol.down button alternatively it will boot you to CWM recovery
Now touch is not working... You can move upper option by volume Up button and downward option by volume down button for selecting the option press power button
Select install >install from SD card or external SD(where you placed a file)
Select flash and recovery will install then for back to exit there is (/) sign which can bring you to previous menu then exit from recovery by pressing vol.up button and power button holding together until it vibrate 3 times now your phone is power offed
6)Now click on flash button on flashtool and select flash mode
Then choose your latest 5.1.1 rom and now do as instruction or your data will lost
1) first you choosed a rom to flash now it will show a dialogue box that how many files are in that rom for flash now on right top you have 2 check box ( data and cache) uncheck both of them.
2) under that you have Exclude box which have check boxes too
Now check all boxes(system,some other things) but make sure only kernal remain uncheck
Now click on flash button
It will ask for connect your phone in flash mode by holding vol.down button and connect the cable
Now it will flash only kernal file all other files will remain same
Disconnect your phone and boot it until Sony logo appear and keep pressing vol.down button alternatively .... It will boot to TWRP recovery which is Easy to use and touch is also working now for get back to normal boot just select last option reboot and it will your
(while you want to enter into recovery keep pressing vol down button alternatively until LED blink green or some other colour.after it blinked you can't boot to recovery)
Hit thanks button if this helped you... And ask if you stuck at somewhere
This was simple tutorial and you are doing this all at your own risk I am not responsible for any damage of your device.

If it says bootloader unlock allowed YES then you can unlock it and use custom roms if it says bootloader unlock allowed NO there is nothing you can do to change it and you can only use stock or stock based roms if you won't or can't unlock bootloader root is still available and so is recovery
