ZenFone Go ‏(ZC500TG) Boot Loop How to fix? - ZenFone 2 Q&A, Help & Troubleshooting

Hello,
Recently I got my Device updated to last firmware, and since after all problems started to appear.
I tried to Download last firmware from the page and to manually install it but failed since mobile is not PC can't read the mobile on USB. (zip file doesn't contain recovery.img or system.img)
When I use recovery from boot screen it shows the logo and stuck
Mobile is not rooted or anything, if there's anyway to recover it, I'd be glad to hear it.

zc500tg boot loop
same problem for me after the last update
I can't enter to recovery mode. tried some combination like volume down + power , vol up + power , vol up + vol down in "no command" page but i couldn't see the recovery mode options

hey I found the solution
1. Turn off the phone, either by regular shutdown or by removing and reinserting the battery.
2. Hold volume up+power button until phone vibrates.
3. Phone should boot to Bootloader Mode. In this mode, volume up is select, volume down is "OK".
4. Using volume up, scroll to Recovery Mode and press volume down to confirm.
5. When you see the "No command." icon, hold power, and press volume up once to access Recovery Mode.
6.download the firmware zip file . place the firmware file on your microsd card and insert it to the phone.
Go to recovery mode>choose apply update from sdcards>choose the firmware you copied earlier>then wait for process completed.
If the installation completed choose reboot system firmware.
The asus logo loading will take upto 7-8mins so be patient.

I'm pretty sure he said he had updated to a later ROM, and the bootloader unlocking isn't there(last version was v39, i think).
OP, if you can, try to reboot to recovery mode, it should be able to let you connect the phone as MTP(storage).
Upload an older ROM to the phone, and then use the recovery to update it with the .zip you uploaded.
Hope it helps! Good luck!

Can't boot into Recovery Vol down + Power?

it just vibes 3 times and nothing? I can get into Rom Manager recovery but why can't I using regular method???
Rooted today using unrevoked....then load Rom manager 3.0.0.8 made recovery from that and now I can't even boot in the Vol up or down + power?
If you pressed vol + and pwr you put it into debug mode. Pull the battery and then do vol - and pwr, it should boot into the bootloader.
Same issue as the O.P.
I press PWR+VOL DOWN and get it to the screen that shows hboot, recovery, fastboot, etc.... BUT I can't access Recovery AT ALL. The VOL UP & VOL DOWN keys do absolutely nothing.
Any and all help is appreciated.
Thanks.
Found the fix... had to remove the p5 img from the sdcard that was used to root the HTC TB. If you don't remove it, the phone automatically tries to load it.
I'm having this problem too only I can't boot into my phone at all. I loaded nerozehl's latest kernel and can't get back into my phone. It just comes up saying "Process system is not responding." I have the radio on the root of the sdcard but don't know of any way of getting it off.
Any suggestions?
EDIT: And I just remembered that I could do adb reboot recovery. Whoops...

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) ?
---------- Post added at 05:14 PM ---------- Previous post was at 05:01 PM ----------
and how can i flash the original rom when adb doesn't detect my phone ??

unable to enter recovery mode

since yesterday i was not able to enter recovery mode. If i press vol up+ power then i can enter bootloader. but when i choose recovery and press the power button, it just reboot the device and enter bootloader again. the device itself is working fine, but i can not ota update
Same
I finally got around to going through the root/bootloader/recovery/rom process, only to get stuck at this exact problem. Rooted and unlocked bootloader just fine, no issue flashing the recovery via fastboot until I actually try to load into recovery mode for the first time. Exact same experience, loads in to flash boot mode, reboots when I try to select recovery mode.
Someone help! I want CM13!

Stuck in recovery after ADB with broken power button

Its very complicated. My T705's power button was damaged by water. And i flashed Stock MM rom with odin. It was fine after flashing, the tablet boot into the os properly, work very well in the os.
But then i want to wipe the cache and data after that, so i was using the code"adb reboot to recovery" to get into recovery mode because my power button was broken. (I thought it can be using home button to select in recovery mode)
But the nightmare is i can't select anything in recovery mode which requiring a power button. So i can't wipe the cache, also can't select the option to reboot my tablet...... I've tried to hold both the volume down and home key to go to the download mode menu, and select restart by holding volume down, but it go to recovery again even after removing the battery, i think it's because the adb command.
And the strangest thing is i can't use my volume up button in download mode menu, so sadly i can't flash the rom again,:crying: but the volume up is working well in recovery and in the os......
Is there anyway to prevent the tablet to boot into the recovery again? I'm quite sure it's not the problem when flashing MM rom, the problem should be the adb command makes my tablet boot into recovery until i change the boot setting in recovery mode.

Holding vol down + home key can boot to the download mode menu.
But the device will automatically turn on after inserting the battery, no need to press any button, but the device only boot into recovery after i use the adb boot into recovery command.

If that's the case that means the power button is stuck on or you wouldn't be able to power on or boot to Download mode.
All you need to do is flash the stock firmware or twrp and it will reboot back to the OS.
Hopefully I've got your fix:
When you insert the battery your device boots up, if so, insert the battery and press the correct key combo while the splash screen from logo.bin is showing to boot into the download mode.
After that flash TWRP latest version with Odin. Then when your phone again boots to recovery, chose Reboot -> System to boot Android.

If the above isn't applicable and you can start Android somehow, I will download either FlashFire or MobileOdin to flash another recovery/ROM.
