have you checked the partition.tbl file? there's some editing as i have red a couple of days ago. it's a known error on some raw firmwares. but honestly i haven't even started using Zenfone yet coz I'm still stuck at boot 😂
and im guessing you're on fake Chinese firmware too is that right? those are firmware versions 2.99 with fake serial. reference was your screenshots uploaded. but correct me if I'm wrong

If u need to unlock bootloader
use auto unlock go to this thread http://forum.xda-developers.com/zenfone-5/general/recovery-twrp-2-8-6-0-asus-zenfone-5-t3136263

[FIX] Asus Zenfone 2 Laser ZE550KL Marshmallow update problem, failed to mount /asdf

I have good experience with other phones but this is my first time working with ZE550KL.
So I took my uncle's phone and he asked me to update his phone to the latest firmware to get the VoLTE feature.
He is was on ZE550KL_WW_21.40.1220.1708 which is Marshmallow of the ZEN UI.
I have downloaded the latest firmware from the ASUS website but I couldn't update it because the recovery which came with the marshmallow update is broken.
These are the errors I got

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Here is what I did, and hope this works for everyone.
Hoping that you already went and searched about the problem over the internet.
These are the things you need to download :
ADB and fastboot
https://drive.google.com/file/d/0B0aDjdU4gTwZZW1HUHhqWnEteXM/view
Recovery image file
https://drive.google.com/open?id=0B0aDjdU4gTwZa1MyUmVPN3BhQjQ
Latest firmware:
https://www.asus.com/in/support/Download/39/1/0/22/ZROQURlyupei1ZQz/32/
1. Download the adb and fastboot drivers. Download the latest firmware and copy it onto your internal storage.
2. Boot into the bootloader.
3. Download the recovery image and paste it into the adb folder.
4. Now type the following command.
Code:
fastboot flash recovery recovery.img
5. This step is very important.
Now, all you have to do is hold the power button and the volume down button to boot into the installed recovery.
Remember that if you restart your phone after step 4, your old recovery(which does not work) will still be there.
6. Now select update from sdcard and select the zip file of the latest firmware you downloaded.
7. It will take at least 10 minutes to install, don't panic if you think the screen froze.
I hope this solves the issues many users are facing.
Feel free to ask questions, I will be very happy to answer.
The recovery we installed is the recovery of Android Lollipop version of the Zen UI ROM.

Thanks. It worked. The only difference is that after flashing the old recovery, my SD card was showing blank. So i selected the adb sideload option and flashed the new build.. Thanks for your guide.

Thanks but few doubts remain. The recovery you used is from Lollipop`s 1.17.40.1503 right?
Can we not do this by installing a temporary recovery image (twrp)?
I have also read elsewhere ( https://devs-lab.com/e-unable-to-mount-asdf-recovery-error-solved.html ) that you would need the boot image too. But your instructions are way too easier and easy to follow. Why don't you use boot image?
If we are using the boot image then which version of it should we use?

Before I tried any of this... First thing I did was boot TWRP and install the lastest firmware.
But I couldn't do so because TWRP doesn't let you flash .img files.
And for the best result it is always better for you to use the official recovery to flash an official firmware.
Because ASUS f***ed up, I needed to install the previous version of the recovery to flash the firmware.
And I'm very happy that my guide worked for you.
Don't forget to give thanks. :laugh:

I haven't tried it yet. So you didn't tamper with boot.img at all. Right?
Also as previously asked what's the build number from which you extracted the recovery.img? Is it from .1503?
My current build is .1708 same as what you worked on. And will data get erased during this process?

How can I boot into the bootloader? is it by unlocking it? or is there any other non-invasive way?
Update: I installed as per your instructions. Device shows "Optimizing app 5 of 51".
Thank you.

Thank you
Thank you sir, this helped me a lot.

recovery link is asking need access plzz help

My Asus Zenfone doesn't boot anymore and doesn't even allow me to factory reset it from the bootloader. How to force reset it??

[Q] Bricked - after TWRP restore - unsuccessful

It is the same problem as written here : https://forum.xda-developers.com/p8...awei-p8-lite-2017-pra-lx1-brick-trwp-t3660664
I've followed every steps, but my phone is still bricked.
My build version is (I guess?) PRA-LX1C432B100
I tried several firmware builds to restore on, but when I try to install it (by pushing POWER / VOL - / VOL +) :
- PRA-LX1C530B130 : firmware versions mismatch
- PRA-LX1C33xxxx : can't install, I don't remember error message but surely the same as the above one.
- PRA-LX1C432B128 : "Installing update" at 5% then "Software install failed" with sub message "Get help from http://www.emui.com/emotiondownload?mod=restore"
I followed the rooting method from a french website that was for build PRA-LX1C432B100 but I can't find this firmware anywhere.
Can someone have the link ? Tried with Firmware Finder.. Now i'm downloading from needrom but still don't know if it's for the good build version...
When the phone boots, it displays :
- HW Logo
- Warning about the BL
- HW logo
- blank
- HW logo
- Warning about the BL
- erestore
When trying to download and reboot from erestore, it says "Getting package info failed" and thus, can't download.
----
TWRP
I also tried to flash PRA-LX1C530B130 update.zip, but I get the exact same thing as here : https://forum.xda-developers.com/attachment.php?attachmentid=4008385&d=1484772172

Any way to unbrick this d*mn thing ?
I need help, thank you.

Your phone is locked. Try the unlocking by huawei unlockcode.

Thank you for this fast answer,
though, where do I enter the code(s) ?
I went to https://tools.texby.com/unlock-codes/huawei/ to obtain my code, is that correct ?
I entered fastboot, no devices found with "huawei code writer"
Same with recovery mode and eRecovery :
{
"lightbox_close": "Close",
"lightbox_next": "Next",

}

Do this command in fastbootmode by adb:
fastboot oem unlock 1234567...... (your unlock code from Huawei.

Oh okay, but i'm already unlocked.
...
FAILED (remote: already fastboot unlocked)
finished. total time: 0.004s

Ok., then flash the stock recovery again and make a factoryreset.

I can't find the stock recovery on internet nor on Firmware Finder. Do you know where I can find PRA-LX1C432B100 ?
I flashed many times on differents build versions those files :
recovery.img
boot.img
system.img
cust.img
Do I need to only flash the stock recovery (if I can find it..) to make everything else work ?
if I have no stock system nor stock boot, will it boot ?
And by "stock" I mean "stock for my device" because I've tried many stock images that end up in erecovery, even after a factory reset in the stock recovery.
-- EDIT --
With the mobile app, it says that the PRA-LX1C432B100 has been removed from the server.

Flash TWRP and see if it starts there.

Ah, but I did it again and it worked.
Go TWRP and I can boot. I can indeed see my build version which is PRA-LX1C432B164.
I can boot, so i'm gonna follow the tutorial again.
Thanks.

System lost perhaps?
It seems that the boot image was lost or erased on your phone, at least you still keep the Bootloader right? it's still alive, so there's a way to solve it, yet, this means the procedure may be hard, but you can make it boot again but your files will be erased since flashing a rom by fastboot usually clears all User Data, follow the steps from here https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-hardbrick-solved-guide-t3657761 but Skip the Blank Flash files, you won't need them (thankfully) I hope this solve your problem

Since the Link contains the Stock Moto G4/G4 Plus rom, you shouldn't have any problem with the Bootloader being locked or unlocked, so try it out and hopefully it will make Android boot once again

As the message says, it can't find a bootlogo. (usually logo.bin). If you've got a locked bootloader, you must have all key partitions, including logo.bin on the same patch level (and as such you may have to flash all partitions).
Which firmware did you try to flash and what flashing commands did you use, and can you show us the outputs of said commands?

Mi A1 Bootloop after ota update and Locked Bootloader

Hi,
I've installed an ota update and the device didn't boot... it is stuck in a bootloop....
When i try to flash via fastboot, it appears an error saying that the device is locked ant cennot erase...
via fastboot oem unlock i get the error message: Remote: oem unlock is not allowed
via MiUnlocker the unlock gets to de 50% and gives an error and on its logs it says: Remote: oem unlock is not allowed
I tryed to flash TWRP with command fastboot flash recovery but the error is the same: remote: partition flashing is not allowed
Can anyone help me please??
I'm stuck on the bootloop i can't go to setting - developer - allow oem unlock option!!

Have you tried doing a Factory Reset from stock recovery?

This is a strange behavior, even if an OTA update corrupted the system for some reason, the phone should boot from the original slot.
Have you tried switching slots manually from fastboot ?

How can i do that?

Hello!
I've faced the exact same problem yesterday.
You need to force the phone to boot in EDL mode by opening the back cover and short circuit 2 pins as shown in THIS video.
After you have the phone in EDL and being detected by your PC (you need the correct drivers, you may get them on THIS thread by @CosmicDan), you may use MiFlash Tool to flash official PIE Rom, access developer options and enable oem unlock to be able to unlock your phone again.
If you wish to revert to Oreo, please use THIS guide.
Cheers!

Actually you have a recovery. You need to long press the power button and, afterwards (not at the same time), press the volume + button. You'll see that all options will appear.
