Shuold I need to check something else ?

The bad block is the issue, so you need to take it to a Service Centre as arpith.fbi said.

So, it is hardware's problem ?
I've see another post that they has same problem of bad block
But they can flash kernel Susessfully.
If I sent it to service center, how do I tell them bad block problem?
I'm a beginner with it ,sorry ....

Messed bootloader unlock

I've tried unlocking bootloader using official Unlock app from Asus
I've the latest firmware 2.20.40.168 unrooted.
I've tried it thrice, all I see is is a black screen with a USB symbol and full white bar below it.
I can't enter the bootloader itself.
I've tried reflashing droidboot.img, boot.img and recovery.img. All says <waiting for device> infinitely.
"fastboot devices" displays nothing, my deivce is not detected!
Yet, I can enter the OS and use it flawlessly!!
Please help me enter the recovery please!
I've attahched the screenshot of the black screen when I press Power+Vol Up (release power up upon vibrate)
Thanks in advance!!!

I cant reach the bootloader, how do I flash a custom recovery? Sorry, I'm no genius...pls guide me with a link!
Thanks in advance

Your phone is bricked! Search for unbricking with xfstk in the zenfone 2 threads. Your phone should be recognized as Moorefield when connected to a PC.
Your other option is to go to a Asus service center or send it to them, but your warranty could be void, because of using official bootloader unlocker!

You said it too fast. He's able to boot to system properly but unable to enter bootloader.
Sent from my ASUS_Z00AD

@krasCGQ
Yeah, you're right! Too fast to say bricked!
But afaik xfstk is the only way to get droidboot/fastboot back.
As far as the phone wouldn't be recognized as any other than Moorefield.
Even if adb can recognize the device, one could not flash droidboot with that, right?
... Or perhaps I'm just talking bullsh*... I'll better quit now... [emoji32]

I'd say bricked too, even though you can run the OS when a new update comes out it won't update if it can't go to recovery. In fact it might just start a bootloop...
If it bricked while using the "Official tool" then I'd return under warranty, it was working fine before... As has been said, the IMEI number was registered with ASUS when unlocked, I just wouldn't wait too long as the longer you wait the less chance of being fixed under warranty.
At the very least you can ask about it and see if you can get it sent back for warranty fix, just don't say anything about flashing anything but bootloader...

It seems to me that this is not necessary with a soc Mediatek.

how you fix it? i have same issue

Here is the way I fixed it
1. the main instruction is here. You need to download your firmware (in my case it's V13.0.2.0.SGDMIXM | 12.0 GLO), and flashtool.
2. Also you need tool to disable SLA authentication. The instruction has its own link to guide, however I decided to use different tool, MTK Auth Bypass Tool V44 from here. You click disable auth, then press volume up+down and connect phone to computer. You need to do it while phone screen is black

}
3. then you are flashing with sp flashtool. Choose your scatter xml file, then press download (you need to do previous step every time you are trying to flash firmware). In my case I've got error about wrong value of combo_partsize_check, so I edited all "<combo_partsize_check>true</combo_partsize_check>" to "<combo_partsize_check>false</combo_partsize_check>", and after that it worked just fine. At least I could boot phone to fastboot mode and recovery, haven't decided what to do next

Hello, you can now restore only the bootloader and the system via fastboot. To do this, download the rom ,, https://xiaomirom.com/en/download/xiaomi-pad-5-nabu-stable-V13.0.4.0.RKXMIXM/#global-fastboot ".
You must have previously unlocked the bootloader via MI unlock tool before you can flash the Global rom .
Then you will have the normal Global MIUI Android on again.

Thanks, but the problem is that I flashed a different rom using the flash tool and accidentally looked the boot loader, after this it won't start, the boot loader is locked and I'm not able to do anything.

You should be able to unlock it again using the xiaomi unlock tool, because it should keep oem unlock setting open.

You must boot at fastboot and Unlovk with the Tool. You dosnt wait 7 days. It works Instant and then you can flash fastboot Rom of your choice

You mean you unlocked a global one and flashed a Europe official rom and locked it and it got stuck?? I'm in the same boat, i have TR and i want to flash EU. I'm waiting the 7 days at the moment to unlock the bootloader. Advice pls
