Unbrick via Lollipop Recovery (Fastboot is dead)

So, I have a ZenFone 5 (A500CG) WW running on a stock-based custom Lollipop ROM (Recreated Remix-Leopard). In an attempt to return to KitKat in order to test some app, I accidentally flashed a bad fastboot.img file. All was too late after I pressed the ENTER key. Although the device still booted and could also enter the stock Recovery mode, attempting to boot into fastboot is a fail (stuck on ASUS logo.)
Now, after an attempt to fix it by ADB Sideloading ASUS' stock 3.24.x Lollipop firmware, my device is technically bricked. Trying to boot it only takes me to the "dead droid" screen (Recovery mode). Attempting to boot into Fastboot (whether Power + VolUp or Reboot to bootloader via the Recovery menu) is a failure. I remain stuck at the ASUS logo.
I've seen the tutorial about unbricking the ZenFone 5 without Fastboot and Recovery (even with ruined partitions) but I found it too bothersome. I'm thinking that since I still have the stock Recovery in my pocket, is there a way to at least restore Fastboot via Recovery? Or better yet, a one-mode solution to install stock ASUS firmware without having to downgrade the Recovery menu (because Fastboot is dead.) Thank you for any help.

to enter recovery mode, u can try key combination :
POWER + VOL UP... when your phone's vibrate, pres VOL DOWN until "dead droid" come, u must release all button then press and hold POWER, press VOL UP Once.

I know that's how you get to Fastboot, but if you read my entire post, I wrote that I could not access Fastboot, whether through hardware (Power + VolUp) or through the Recovery menu's "Reboot to bootloader" option.

sorry, i just read that u want install stock fw. everything is ok if u can access recovery without any error...just sideload via adb (do downgrade/upgrade).

It's cool.
Yea. I tried doing that. Doesn't work:
I have the Recovery mode for 3.24 Lollipop FW. If I tried to install an older one (i.e. a KitKat stock ROM), it just throws me an error saying that I can only sideload an older FW. However, if I tried sideloading the same 3.24 FW, it just throws me an "Unknown command" upon the sideload reaching about 36%. It's always been like that, I can assure. I am very certain it is not caused by a faulty data connection.
Any way around this? Thanks!

Stuck in fastboot. Can't access eRecovery.

Hi all,
Please help me!
I think i messed up pretty badly here. I tried downgrading from Oreo to Nougat but I think I tried to install a wrong image. Now when i boot i get:
ERROR MODE
Attention! Please update system again
Error!
Fun NO : 15 (bl31 image)
Error NO : 1 (security verify failed)
I've tried the dload method but it doesn't even start. I boot it up holding power, vol+, vol-, and it gets stuck at "your device is booting now."
I can't access twrp, even after flashing it again.
I can get into fastboot and I've tried manually flashing images from an update.app, but after that, the same problem still persists. Trying to relock the boot loader gives an error "command not allowed"
Does anybody have any ideas?

yes i have same because battery is not dead still wait battery remain if dead then plug against work fastboot need firmware rollback version only C432B185 try HWOTA this is the best

So you're saying that I wait until my battery drains, then go into fastboot and roll back to C432B185? Maybe you could help me by outlining the steps to flash via fastboot?

flash via fastboot by HWOTA follow this link https://romprovider.com/2018/01/download-install-b185-nougat-update-huawei-p10-plus/

So i tried this method, but it didn't work. It flashes TWRP, and instructs me to disconnect the USB cable and boot into TWRP, but i can't boot into TWRP. It goes directly to the error message even when holding the buttons down.

because stuck in fastboot is freeze or corrupted still wait battery drains when dead battery hold vol down + plug USB then run in HWOTA...............

So after waiting for the battery to drain, holding vol down, and plugging the USB, I'm back where I was before with being in fastboot. Running HWOTA results in the same problem for when it tells me to reboot to TWRP after install, the phone goes to error mode.
I'm pretty sure the bl31 image corruption is preventing me from booting into recovery.

try other methode if work or not run fastboot need files from huawei firmware extractor open Update.app save files boot.img + recovery.img + system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
Test it

Ok so i flashed boot.img, recovery.img, system.img all OKAY.
Reboot and i get the same error..
The problem is with the bl31 image, which is in ARM Trusted Firmware.
Maybe if i could figure out how to flash TRUSTFIRMWARE.img that would work. I tried this, but it doesn't work. I don't know the partition name.
fastboot flash trustfirmware
unknown partition 'trustfirmware'

Try HWOTA flash TWRP then hold power + vol up stay hold vol up long 15 seconds

Hi
I have the exact same problem
After trying all of the methods I found (dload, HWOTA, TWRP, etc), I finally took the phone to the service center.
They told me it was an easy fix, then they called me and told me that probably they were going to replace the motherboard
I'm still waiting for them to call me for confirmation.
If you got any news on this, please keep posting
Thanks!

I actually ended up using dc pheonix to fix it. It worked perfectly. I had to pay about 15 dollars for credits. It used some sort of backdoor and flashed a new ROM from scratch.

It should still be able to do force update or at least fail to do it. Make sure you have like >70% battery. Put UPDATE.APP in folder named dload in your sd-card and hold 'vol -, vol + and power.'

If your phone still boots in rescue mode, then I think the rom you've flashed is not compatible with your phone. As @up said, try to force an update.

The only keyboard shortcut that works is v - and power for fastboot mode.

I came up with the following solution:
1. Flash TWRP (fastboot flash recovery <path>.img)
2. Type fastboot reboot and then unplug the usb cable as fast as you can and hold vol+ to boot into twrp.
3. Wipe -> Swipe to Factory Reset
4. Wipe -> Format Data
5. Download B896_update.zip
6. Advanced -> ADB Sideload -> Swipe to Start Sideload
7. adb sideload <path_to_b896>.zip
8. Once the process is finished, reboot the phone.

What were you trying to do when problem started. It probably won't do anything at your state, but have you tried to hold vol+ in fastboot mode, normally it should go to eRecovery.(not that you can do anything with it, but would be good to know)
Also try things with usb cable plugged and un-plugged this really makes difference in some cases.

I have unlocked bootloader (i used this method:https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701).
I tried with other twrps, like elite twrp, twrp, and from the quide that i mentiond, that twrp too.

Hello,
if i'm correct you are still on android 6.x/emui 4.x.
You used SRKTool so why haven't used that tool to flash recovery too ?
It's included in the tool.
You need 3.0.2-0 for your android version.
If you want to flash it with fastboot, when finished
disconnect from pc and manually reboot recovery holding vol+ and power buttons.
Cheers

Android 6 > TWRP 3.0.2-0
Android 7 > TWRP 3.1.1-1
Ensure you have drivers installed in your pc.
Ensure you have OEM unlock and DEBUG USB enabled in developer option.
With fastboot: >>> fastboot flash recovery (name of recovery).img (ensure you put the recovery inside the fastboot folder)
>>> fastboot reboot recovery or shoutdown and reboot holding vol+ and power buttons (until it boots in TWRP).
Done.

Thanks. I managed to get it working more przez less. Now i have two recoveries . One accessible while holding vol+ during power up and stock recovery when i press vol+ for 3s on "your device is unlocked and therefore it should not be trusted" screen.

The system has been destroyed please help

So I flashed the stock pie rom from this forum, came from pixel experience 9. After I flashed the ROM I also flashed the twrp installer and when I rebooted it says the system has been destroyed and press the power button to shut down. I can boot the phone in fastboot but it doesn't recognise it even though the drivers are installed and it worked perfectly before. The miflash program also doesn't recognise anything after I press refresh.
Is there anything I can do?

Thanks for the solution. Worked for me as well for similar problem. A simplified step by step if anyone still couldn't get it to work.
Power off your phone as asked by the Error Message
Press Volume Down + Power button simultaneously to boot into fastboot.
Load Command Prompt in the ADB/Fastboot folder in your PC (ADB and other drivers need to be installed)
Type "fastboot continue" and press enter
And you are done. If your phone is not recognized by the PC (after you put it to fastboot mode) make sure you have proper Drivers installed for your devices. You can use MiFlashTools to install required drivers automatically.

Thanks for this. This happened to me two weeks ago, had to completely flash stock rom and begin from zero. Hopefully others will see this and avoid starting fresh.
