Hi.
i got this phone from a friend, and he said it was broken (didn't say how) and it didn't turn on.
when i plugged it into my computer with a normal usb cable, it showed the phone as "Forge HS-USB QDLoader 9008 (COM4)"
iv'e tried to boot in fastboot and recovery, but the only thing that happens is that it reconnects in the same mode.
iv'e also tried to use fastboot flash anyways, but it didn't worked. same goes for adb.
if any of you have a answer to this (that don't innvoles a jtag or any box or cable like that) i'll appriciate it
(PS. Im new to this forum)

Long time ago, my phone had the usb host mode problem when plug in into pc, but can charge at OS. So i didn't bother it because it still can transfer files to PC via USB OTG.
Last month, itself random went into usb host mode when charging and the phone totally cant charge, need to restart then its ok. When i go into fastboot it shows FASTBOOT AC and then FASTBOOT randomly (like gotten shock) and after awhile the problem gone so i didnt bother about it.
Last week, I unplug my phone after i wake up and then itself shows USB HOST MODE, so i tried connect USB OTG and then it didn't works. I thought it was kernel problem so I downloaded ElementalX 18.2 and then i flashed it. Now, after boot, the phone wont charge. It only charge when powered off and RECOVERY mode. Fastboot shows no sign, no FASTBOOT AC or USB, even OTG power. This is strange and weird.
Also, i flashed ARHD 81.0 at older version of TWRP Recovery, and then after i got that problem, i reflash my phone with TWRP 2.8.0.2, at the end it says : "set_metadata_recursive some changes failed" , and the phone can't boot. Luckily i got a nandroid of it so i flash it immediately. It can boot, but the no charging problems still exist.
I later upgrade my TWRP to 2.8.3.0 via TWRP Manager, still get "set_metadata_recursive some changes failed" problem. But, I found out that after i flash the rom, then flash nandroid, when i boot into OS with charging, it can charge in the OS, but not anymore after i went into fastboot or recovery.
And something interesting is, when the phone boot, haven't load the drivers, itself began OTG mode and powered up my powerbank, PLEASE HELP!! Im totally stuck on this!
Does this is a hardware or software problem? Its this the USB board broken or the motherboard? Please respond..
Sorry for my bad English.
problem solved, thx guys
my damn usb cable was the reason why fastboot did not change to fastboot usb
new cable, no probs
yay!!!!
hope anybody can help me....

if i start the phone its starting 1-3 secs as normal than it stucks by the anDROID logo...
but if i start into the bootloader mode/fastboot - i can`t start recovery cause the phone restarts after that in the bootloader mode.´again...

if i want to do anything by ADB-console/cmd-console the computer can`t not find my devices

Hello everyone.
Yesterday while i was trying to install a new rom in my MI5 I bricked my phone.
I wiped the system, data, cache and kernel cache, then, as a mistake I rebooted my phone and all of a sudden it turned black and I couldn't go to the recovery or fastboot.
Now the phone is just black, no response trying to boot or go to recovery\fastboot. When I put to charger theres no LED LIGHT.
So I installed the adb drivers, installed MiFlash, and the computer recognized the phone as QualComm HS-USB QDLoader 9008 COM4.
Then I installed a fastboot rom into the phone using MiFlash, it said flash done and successful.
But, it keeps freezed in a black screen.
Should I just wait for a miracle or theres another option?
My PC still recognizes the phone as QualComm HS USB QDLoader 9008 COM 4.
Thanks in advance.
// EDIT (SOLVED)
Ok so now it booted with the fastboot ROM I flashed.
As I see, after the flash it takes hours to boot. I just went home, dropped the phone in the bed, then I pressed Vol up+Vol down and power button at the same time for two minutes and worked.
Hello all, I have a strange problem on my xiaomi 8 phone.
Every thing works fine, the phone is BL unlocked, with global rom installed and can be OTA-updated.
Now I want to re-lock the Bl (because of google pay), so I booted to fastboot and the strange thing happens. When I connect to the usb port of my win10 pc, nothing happens, the device manager also show no new device or unknown device. And I als connected to my ubuntu server, dmesg show nothing, and lsusb also show nothing new.
So the issue is, in fastboot mode, my phone seems not be responsed the usb connection. This is boring, because I also accidently replaced the twrp with stock recovery, now I can do nothing on my phone without the fastboot connection.
Any one has an idea or simillar issue and have a solution for it? Thanks in advance.

It sounds like you accidentally relocked the bootloader.
If so you will need to repair the phone in EDL mode by using QPST. There are plenty of how to guides available. You can buy a EDL cable from Amazon

I have been using the phone for almost two years, without any problem, with a ROM from xiaomi.eu.
One day the phone suddenly went off, and I couldn't turn it on again. When I plugged it into the PC it recognized it as QLoader HS-USB 9008. I tried to flash another ROM but could not go into fastboot mode.
I decided to open it and unplug the battery, in case it was still on and without a screen, and when I reassembled it, I was able to go into fastboot mode and flash. MiFlash never gave the termination notice, and since then the phone has not responded, the computer does not recognize it, nor does it react to anything (it no longer recognizes it as QLoader HS-USB 9008). I've tried an EDL cable to do deep flash, but it doesn't work either.
I have read that there are some test points to start EDL mode, but I don't know if it will work. Do you know if it would work for this case? I also haven't managed to find a good manual to do this.
Any other idea?
Thank you very in advance.
