Recovery mode never shows up even after it's selected and restarts - ZenFone 2 Q&A, Help & Troubleshooting

I was attempting to install a custom rom and now I can't even get into recovery mode. The option comes up after entering the bootloader but then it just reboots to the bootloader screen. If I pick normal boot it does the exact same thing. Any help much appreciated.

Can you flash from the bootloader? First thing to try is clear cache, be patient it's a slow process, if that works then flash a pre-rooted rom, you can find the in the thread to flash ww from cn. That should get you running again

I can't get to the standard recovery to clear the cache or to flash a prerooted rom. It seems I can talk to the device with my pc using fastboot but not adb. I did clear the cache by running the command "astboot format cache" but it didn't seem to help.
Thanks

did you run the offical Bootloader Unlock from asus? if so u will need to wait for a fix.

no I have not run that. I think I need to reflash the original img files using fastboot does that sound right?

The reason I had you run clear cache was to make sure fastball commands works, you need to flash new rom from fastboot, look at the thread to flash WW from Cn it will give everyone you precise instructions and d/l locations for the images to flash and fastboot commands I would post the link but can't copy it from this app, sorry, but the thread is titled flashing from CN to WW

Did you do a full wipe before flashing? And are you using a compatible recovery?

Do i need to delete my old recovery ( clockwork mod) or do anything to that recovery before flashing this one?
Your best bet is to flash that mod twrp. If it fails,I suggest u flash that ruu
---------- Post added at 02:08 AM ---------- Previous post was at 02:03 AM ----------
What I mean is...flash that recovery then reflash your ROM. If u still get reboots, just flash that ruu...I don't think a certain recovery will interfere with flashing an ruu

But your bootloader must be locked. You will have to unlock bootloader again after running this ruu..this ruu can be ran if all other things have failed. Its kind of like a factory reset to make your phone start all over

can someone help me i cant boot into recovery, and apps are still FCing.
Symptoms:
-Unable to boot into recovery/bootloader
-Force closes system app or installed apps
-Stored settings changes on reboots
-Random reboots while phone is idle
-Constant reboots while restarting it and doesn't know when it will boot normally.
All above mention symptoms are related to HARDWARE FAILURE! Bare in mind that not all of them you'll see it on your device. But any of one you face,will might probably having chance of hardware failure.
You or here on xda users can't resolve your issue. So don't try anything from now on wards. Use it as is. Or sell it and move to another device.
Unless you have some local cheap repair shops where they might evaluate the issue then fix it that way,rather than calling into HTC service center.
And i forgot to mention, you probably have question in mind, How i know? My device is dying too. It reboots constantly before it boots normally,though it works fine. So symptom may vary device to device but cause is the same.

And clearing cache in stock recovery is very slow, so you likely corrupted something by rebooting before it was completed and returned to main screen

Yeah on fastboot but not on stock recovery.

I did the exact same thing not realizing it can take up to 15 minutes for the cache to clear. What I did to recover was boot into fastboot. Get my PC to recognized my phone. The ran the fast boot tool from the command line. From there I fixed my cache partition by running the fastboot erase cache command. After that I downloaded the stock recovery for the latest build then flashed that. After that I was then able to boot into adb mode from stock recovery. Then I downloaded the factory image of the latest build for my model of phone from Asus website it was around 1gb. From there I placed it into my adb directory and ran the adb sideload nameOfImage.zip and that side loaded the image back onto my phone fully recovering it. And nothing was last everything remained intact. I did not need to do a full wipe or anything and I was back up and running.

Deleted the Asus ui by accident, help needed

Help as i deleted the Asus ui, i had made a back up but can not access them as

Shouldn't matter as long as you can reflash the firmware back on the phone... Any changes will be rendered moot as the whole firmware is re-installed, not just the stuff you didn't change...

HI
First of all thanks for helping. How do you flash the phone as only a novice at this.
This is a running ASUS ZenFone 2 ZE551ML v 5.0. The phone is rooted and i made backups onto the sd card
but do not know how to reverse the operation.

Why leave XDA? Here's all the info needed in one thread - http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596
You can also get the latest pre-rooted firmware, sorry 2.20.40.63 not 40.90, from the pre-rooted firmware thread in Original Android Developement...
It's the same end result, xda thread ultimately finished up at chinaphonearena site, it is shakalaka who compiled the roms, so either is a good choice.

I rooted my devide and then I tried instal the slim via TEMPORARY CWM which I think was my mistake all the way...
After I installed the slim rom the device gave me the option to restart which I accept and from that point I got the error msg with the android laying down and the "Erro!" msg...
Cannot get pass from that point, tried everything and I'm start to geting worried.... I cannot even access the sd card from another device since there is no sd card :|
sorry about my bad english...
Edit: I managed to enter in the recovery mode, already tried the wipe data/factory reset and wipe cache partition and nothing seem to work... still receiving the erro msg... I'm out of option man, I'm kinda new to this root/rom stuff and I think I got screwed in my first attempt :\
Edit 2: there is a ADB option, apply update from ADB, is there anything I can do with this option? I already dowloaded I stock version from the android...
You have 2 options, 1. Sideload from stock recovery the full zip of stock Rom or 2. flash via bootloader, w/adb sideload make sure you are on (adb 1.0.32) or it won't flash, if you choose bootloader option refer to the flash WW from CN tutorial located here in xda or search in chinaphonearena for shakalaka tutorial

Volte/Advanced calling fix - open for discussion

I'm copying and pasting the steps below from another thread in this forum and hopefully users here can help other users with any issues, questions, etc. I mean, that's what this 'community' is for, right ?
Remove volte from account (If already enabled)
Then latest ruu and factory reset
fastboot erase modem_st1
fastboot erase modem_st2
Then reboot and try volte activation

Thank you for reposting this. So we need to figure out how to remove VoLTE/advance calling off of your account as a feature than figure out if we can just flash custom stock ruu rather than just going completely back to stock. Maybe @dottat or anybody can shed some more light that has done this.
