I cannot start the install - Zenfone 8 - Your device is corrupt

/e/OS Devices Asus

I am trying to install e/os/ on an ASUS Zenfone 8. I read a lot of thread without success to understand what I do wrong.

I am following
https://doc.e.foundation/devices/sake/install

I did’t found unlock bootloader on asus website and the device was sold with an “unlock” mention (backaret). aybe I did a mistake here, I jumped to the next chapter

I flashed a vendor_boot
https://mirror.math.princeton.edu/pub/lineageos/full/sake/20240903/vendor_boot.img

$ fastboot --version
fastboot version 1:8.1.0+r23-5ubuntu2

$ fastboot flash vendor_boot vendor_boot.img 
target reported max download size of 536870912 bytes
erasing 'vendor_boot'...
OKAY [  0.003s]
sending 'vendor_boot' (98304 KB)...
OKAY [  2.776s]
writing 'vendor_boot'...
OKAY [  0.183s]
finished. total time: 2.962s

Chapter Temporarily Booting a custom recovery using fastboot

$ adb devices

Gives me nothing
so I used “restart bootloader” from the phone (another mistake ?)

I used the https://images.ecloud.global/dev/sake/recovery-IMG-e-2.3-t-20240820427106-dev-sake.zip

$ fastboot devices
M5AIB760L728JNZ	fastboot

Manually booted in “recovery mode” in the phone

Your device is corrupt. It cant be trusted…
Then it reboot
Scary :slight_smile:

I maybe could flash an android classique but I don’t know yet if it is the good thing to begin freshly and how to do it

Some links I keep

nothing in helpdesk

This device is no longer supported I believe. Asus stopped allowing the bootloader to be unlocked. On the doc.e.foundation/devices page, it shows this now but didn’t when I originally tried.
Are you attempting to get past this?

surely carrier unlocked !
but not bootloader unlocked…

on this page, you can read :

Please note ASUS bootloader unlock App service are not functional for the past couple of months. Only users with devices which are already unlocked should proceed with the installation

i am afraid you will have to find another device…

here is the recovery-IMG-e-2.3-t-20240820427106-dev-sake.zip content :

Did you tried using vendor_boot-e-2.3-t-20240820427106-dev-sake.img ?

adb only works in normal mode (when allowed in developper options) and in recovery mode

what is your actual recovery looks like ? (take a photo)

You are right, flashing Stock OS is the way to restore the device.

@piero do you have a link to do so I could have a device back ?

On XDA forums i found this official download link from Asus :
https://www.asus.com/mobile-handhelds/phones/zenfone/zenfone-8/helpdesk_bios?model2Name=Zenfone-8

And in this other thread, it seems to provide HowTo :

Sorry how to get a bootloader on the smartphone when it is locked.
in the screenshot it is (Device unlocked: false).
a flash only works with (Device unlocked: true). should you not get the bootloader unlocked I don’t see any hope.

Note a carrier unlocked! refers to the sim card.

To use your smartphone again, you must install the Stockrom.

good success

I was trying to understand your question! :rofl:
As I understood it:

You are trying to install eos on an asus zenphone.
This is no longer supported.

I know this because I tried previously before the eos install doc was updated to say that asus no longer allows for unlocking the bootloader.

Given all of this, I was asking if you are nonetheless attempting to install eos by finding a workaround.
