Hi. I have a Lenovo TB-X304F that I unlocked and flashed successfully with TWRP, but I screwed up and then managed to brick the device. It now goes to black screen after showing the Lenovo boot image briefly. However I can still access Fastboot and Recovery.
I did backup Boot, Data and System before all this and I have restored these succesfully via TWRP, but the device still won't boot and is stuck on the black screen.
I want to flash stock rom again, and I have downloaded "Lenovo Tab4 A10-TB-X304F_S000038_170703_ROW_QFIL" which is available from some websites, and this is meant to be flashed with QFIL. The problem is that when connecting the tablet, QFIL is always stuck with port "Qualcomm HS-USB Diagnostics 900E (COM21)" which results in the error "Download fail:Switch to EDL fail Failed to switch to Emergency Download mode" when I try to download the firmware. It seems some have solved this issue by modifying a USB cable, but I'm unsure if this would actually help me.
Can anyone help me resolve this, please? Could it be possible to get a TB-X304F backup that perhaps works, when for some reason my backup doesn't? Does somebody have a stock rom that can be flashed using ADB or TWRP?
Very grateful for any help with this. Thanks.
Try using MiFlash not Qfil to flash stock

Thanks a lot for your reply! Do you think MiFlash can flash the file that I mentioned above, though (Lenovo Tab4 A10-TB-X304F_S000038_170703_ROW_QFIL)? I believe I was trying out MiFlash as well but it seems it requires another type of file to flash?

unbrick "dead" tablet Lenovo TB 4 10.1 (X304F/L)
I managed to identify the test point on the motherboard. This allows the tablet to switch from Qualcomm HS-USB Diagnostics 900E driver mode to Qualcom HS-USB QDLoader 9008 mode. My tablet could not be booted into bootloader, recovery or system...

Hi everyone.. Can someone guide me how to get my phone to be detect back as Qualcomm HS-USB qdloader 9008 instead of this Qualcomm HS-USB Diagnostics 900E.. Actually i was flashing a rom using miflash but since i didnt select flashall below.. i made the mistake of closing the miflash before the flashing was done.. Since then i cant get the mob to be detect as qdloader so it can appear in miflash. The phone right now is still in fastboot. Please is there any way to revive my phone? :crying::crying::crying:

This works for people who are able to get to fastboot. I am not able to get to fastboot at all. Only EDL. Please help. Any other alternative?
Can you please check this thread.
I hope this helps.
You remind me of myself
I did the same thing in April and had to go to service center as i couldnt make it work that time, they fixed it within 24hours
But now there are lots of recovery methods that u could try

Try deep flash methode, just need to buy deep flash cable in market. For the guidance, please try to googling it in miui forum due to already available there.
Yesterday, one of my friend succesfull to restore her kenzo from diagnostic mode and really happy with the result.
Try the simple deep flash method mentioned here -
http://en.miui.com/thread-310325-1-1.html
I was able to recover my rn3 from 900e mode using this.
It's very simple and easy. You just need a copper wire strand to do it.
Use Deep Flash Method
I had the exact same problem so I tried deep flash method. It worked and my phone was detected by the PC as 9008. Then I could flash the fastboot rom using Miflash tool. Hope this helps.
i've deleted the system partiton when i try to flash cm14 in safestrap twrp.
so i downloaded the stock rom, rename it from *.bin to *.zip in order to install it in the twrp.
and i installed the newest twrp in fastboot mode after unlock sucessfully.
Finally, the black out happened. no pic in any time, only find qualcomm hs-usb qdloader 9008(COM4) when connect to PC make me know it still alive.
As far as I know qualcomm hs-usb qdloader 9008 means Emegercy Download Mode. the I tried some tools such as QFIL and Miflash, but nothing good happen.
It didn't work either when I found the link below

I accidentally flashed Redmi note 3 firmware into Redmi note 4. Now only red light is blinking. No fastboot also. Computer showing in ports Qualcomm hs usb qdloader 9008 (com3). Please help me flash full fastboot rom
if your computer detects your device as qdloader , that means it is in EDL mode, in this mode , you should be able to flash fastboot roms using miflash , you should read this thread first, http://en.miui.com/thread-565784-1-1.html . although the thread writes about flashing in fastboot mode, but it shouldn't differ alot from flashing in EDL mode, just follow the B part of the guide in the link, MIFlash should be able to detect your device and list it down as COM(number) .
As for the driver part, you shouldn't need to update anything if MIFlash can detect your device , as your computer already correctly detects it as QDLoader

Thankyou for your valuable reply. Miflash detecting device. But error in flash. Then removed back cover and removed battery connection also. Then Miflash flashed the rom successfully
Device is stuck in EDL mode - screen is black, no response to pressing keys or any combination of keys.
Linux recognizes the device as:

After some searching, I found out I have to reflash firmware with QFIL.
I have downloaded stock firmware: RMX2202export_11_A.17_2021120715030199.ofp.
Next, I have looked around for a step-by-step guide for newbie. For sorry, I hove found nothing helpful.
May I ask some tips how to reflash stock firmware using, QFIL tool and OFP stock firmware?
Or, is there another way to unbrick Realme GT [RMX2202] whitch is stuck in EDL mode?

I believed u have hard bricked ur phone. The only solution I can think of is to find someone to flash the stock rom by using MSM download tool. But they usually charge u for a fee for doing that since u need the id and password to access the tool.
