COOL1 BRICKED QUALCOMM HS-USB Diagnostic 900E

After using my cool1 for a month with no problems i decided to flash JUI 7.0.1 (with gapps etc...) on my Cool1 via TWRP but after doing it i realized it has many bugs and apps doesn't work properly. So i decided to return to EUI. After flashing the original stock firmware and rebooting the phone automatically switched off.
Power button not working, i cannot get into recovery and i tried all combinations of buttons without success.
When i connect it to the computer the red led start glowing and my computer recognizes it ONLY in Device Manager as QUALCOMM HS-USB Diagnostic 900E (COM3).
i have all the latest drivers installed.
i tried QFIL and it also recognizes it as QUALCOMM HS-USB Diagnostic 900E (COM3) and after setting everything when i click "Download" i get this error:
Start Download
COM Port number:3
Switch To EDL
Download Fail:Switch To EDL FailFailed to Switch to Emergency Download mode
Finish Download

MiFlash doesn't recognize the phone so nothing to do
Coolpad Download Assistant doesn't recognize the phone.
YGDP not working
to flash a new rom i need the phone to go into QUALCOMM HS-USB QDLOADER 9008 MODE but i tried everything installed the latest drivers even bought a 10$ EDL CABLE from amazon still not working always show me QUALCOMM HS-USB Diagnostic 900E
Any suggestion that would help, please... I think it's hard bricked because it cannot get into recovery nor the fastboot mode. completely dead only Red led glowing and QUALCOMM HS-USB Diagnostic 900E (COM3).
Thank you

hi
i installed custom recovery to cool 1 c 103
after it finished model number changed to 106
what i have to do?????

So nobody could help?

hello. probably you wipe system. .. or i dont know..but try this:
Forced writing a recovery mod using QFIL.exe:
a) open program qfil.exe
b) choose the recovery folder and xml file
(remember: for writing succes recovery you need type this command in cmd: BCDEDIT.EXE –SET TESTSIGNING OFF)
c) plug the phone
d) now. most important: Hold Volume up , Volume Down and Power Button At same time. and - always press the button
if not working : first d) and then c) steps.
if the qfil.exe read the phone hold continues button.
e) press download button on qfil.exe
Now in this moment you have a recovery mod.
This method it worked for me
So now you need a flash a rom.
I dont understand why after flash some room(miui 8, 9, etc) my phone did not open..
maybe some rom dont have a kernel
so.. i flash the jui 7 by cuoco and my phone its a live ()
now you can try flash now room (I'm not sure if it will work as I did not try)
1. wipe data and cache
2) flash new rom
edit: dont work flash any rom after flashed jiui..i dont know why......
Edit2: for change jui to eui watch this:

ZTE Axon 7 Mini Hard Bricked

I was trying to update my Axon 7 Mini with an update zip from here https://www.ztedevices.com/en/support/detail?id=03743F4E761C475F838D444384791D36
Extracted the update.zip from the download. put the update.zip in the root of my sd card. Applied through recovery using sd card update. The phone accepted the file. Said it was successful. I wiped the cache partition and selected reboot system. The phone never turned on again. No signs of life whatsoever. Plugged into my desktop PC. Windows detects it but doesn't recognize it. I need some MAJOR help please.

Can you enter the recovery again by pressing volume up and power simultaneously? If not, then you will probably need to enter emergency download "EDL" mode and flash firmware using EDL Tool. Do you have an european version of phone? On my Axon 7 Mini I just upgraded directly from Marshmallow to Nougat without any problems.
So, how to enter the EDL mode, please look here:
https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413
Maybe you will need the EDL cable or you can try this "DIY hack video". - I had also bricked phone and this video helped me a lot!
When the phone is in EDL mode then you will need the firmware and EDL Tool for flashing.
Good Luck!

Windows doesn't recognize it in through the usb drivers in EDL mode so idk if it can go into that mode manually. Definitely not by command prompt.

First: did the DFU see a com port in the config?
You do have to select the com port manually.
Second: can you boot to FTM?
Third: try another Edl package, some Edl have to be installed as a backup restore not via a straight flashing.

thx for quick answer!
1 see pic pls, in DFU com4
2 no can not get to FTM
3 tried 3x another packages...see log/pic from ZTE EDL tool...

Use the latest MiFlash. I've been having trouble with EDL Tool lately. Maybe it'll work. z
I'm guessing the red LED turns off as soon as you connect MultiDL correctly?

Make sure Edl tool is in the root directory of you PC or laptop drive.
EG: C:\ or D:\ as per the instructions.
Make sure you run it as admin too.
If I remember correctly the full Edl package had to be placed into the appropriate folder as per instruction (via the tool) and on the post.

@Syberclone:
I have all as you write...in root, edl package is correct/about edl package edl tool says "success = tried 4different edl package for my phone"/
I´m convinced about a port problem, log from edl tool is:
15:47:25: INFO: User wants to talk to port '\\.\COM8'
ERROR
15:47:25: {ERROR: OpenPort:5198 Failed to open com port '\\.\COM8'
I´ll try another miflash but dont believe ...:-/

just used another PC with WIN7 and now.....CHEEEEERS!!!!!!
Thx to all!

As of now, I can't boot into phone( system), can't get into edl mode with button combination but, i can go into dfu mode and use a tool to go in edl mode.

Have you tried to completely drain the battery?
Hi friend:
If you drain the battery completely it will be easy to enter edl.
You can use edl tools to unlock the bootloader.
What I would do would be once you have the battery drained, connect the pc and flash a stock edl nougat rom.
Once flashed and started the rom, it will be easy to unlock the bootloader, put twrp and install what you want

Thanks for your response !!!!
yes i tried with drain batteri two times but no progress , it's just on naugat rom and stuck on logo , i tried also to unloack bootloader , it told me unloacked on the edl tool but when i boot on bootloader , the state is locked , may be because the rom naugat not flash correctly , or because it'stuck on logo .
i try with naugat b12_Full edl ,oreo b02 _fulledl , , but it told me failed this time otherwise at first naugat _b12_full edl say successfully done.
now i just can make phone on dfu mode and try with the edl tool of dijkiz to go automaticlly to edl mode and flash , but it told me failed flashing .
what i should do then !!! can u recommend to me a stock rom naugat and give me a link about it , i can flash it with edl tool and how i can directly go to edl mode because now i just have dfu mode then i use a version of edl tool make me go directly to edl mode but may be it's not work fine !!!
Ps : My problem is that am stuck on logo after downgrading from stock rom oreo b02 to naugat , shoyuld i search about a boot recovery to flash boot and boot in system or if ther is another tools or rom can i use them to solve my problem
(' sorry for my bad english )

How to Boot into Fastboot from EDL Mode?

Dear fellow members,
The camera app in my father's Poco M3 couldn't connect to the camera. So, I decided to flash a fastboot from Mi Flash Tool. Unfortunately, I picked the wrong firmware to flash, i.e., flashed the global version instead of the Indian version. Now the device is bricked, I can't boot into fastboot again and am stuck in EDL mode. When connected to a PC the device is recognized as "Qualcomm HS-USB QDLoader 908 (COM20)"
Tried flashing the Indian firmware using Mi Flash Tool. Mi Flash Tool asks for an authorized mi account and the process is stuck in "edl authentication".
Currently, I'm draining the battery using a rubber band+cotton bud in hope that it would boot into fastboot after showing the charging logo once the battery is drained.
The Bootloader in Unlocked
The Previous Firmware was Indian
Windows 10
