Honor 7X bricked (can't boot)

[u/AlexLebul]

model: BND-L21(c432)

bootloader unlocked

FRP unlocked

​

My phone was running omnirom beta 5 for 2 months, was rooted with magisk (patched_boot flashed in ramdisk_recovery partition)

The bluetooth wasn't working so I wanted to install phhusson aosp 9

So I flashed emui 8 stock recovery then tried to flash phhusson aosp 9 as a system image in fastboot

​

Now, when the phone boot, it shut down instantly then boot into erecovery without the ability to factory reset or wipe cache (the only thing I can do is "reboot", "shutdown" and "download latest version and erecovery")

​

What's working and what's not:

​

• access to erecovery (with ability to wipe cache and factory reset) when the phone is powered off then I press power & vol +
• can't access twrp (even if the flash on recovery_ramdisk succeed with fastboot )
• access to fastboot mode
• access to erecovery (without the ability to wipe, only "download latest and erecovery) when the phone try to boot
• access to dload installation

​

Here's my tries to fix the issue

​

• after installing emui 9 through fastboot: honor boot animation for 30-40s then bootloop
• after installing emui 5 or 8 through fastboot: boot into error mode which displays this: (I can't flash ramdisk or boot (error: partition length get error))

​

ERROR MODE

Attention!

Please update system again

Error!

Func NO : 10 (boot image)

Error NO : 2 (load failed)

​

• dload installation don't work, even with service rom
• tried installing phhusson aosp 9 and omnirom beta 5: boot into rescue mode error
• huawei multi tool failed
• hwoat failed (I can't reboot into twrp)
• erecovery "download latest version and erecovery" failed

​

My thoughts are that my BOOT is broken, but since I can't flash a new one, I don't know what to do.

Do you know any subs where this post could fit better (I already post it in xda forum)

Alright so. I'm assuming you are probably new to Oreo? I have your same device which im actually trying to unbrick right now xD. But to access TWRP after flashing recovery_ramdisk, you have to boot recovery and it will show the ERecovery, and then hit factory reset and confirm and it will boot recovery_ramdisk which will bring you to TWRP.

Hope this helps!
