I was searching for international Nougat roms for my Leeco cool 1 dual. I found 3-4 roms mosltly by Cuoco. But all have major issues whith this C103 device. No WiFi, not enough brightnes, no video capture, no mic.
I decided to turn to original MM rom then. But first i wanted to replace the JUI TWRP (One of the roms has installed it) with 3.2.1.0 TWRP. I make the flash without any errors. But after the restart of the device, JUI twrp logo appears again. But phone not go in the recovery. Just stays in Nougat twrp logo.
I tried to go in bootloader mode. Fails.
I tried to shut the device off. Fails. Its turn on by itself and stays at JUI recovery logo screen
I tried to go in recovery mode again. Fails.
I tried to put it in EDL mode. Fails
Then i decide to let the battery drain, and after that i put it in Bootloader mode. Then....
I tried different versions of Coolpad download assistant (latest v 1.59) in order to flash a new rom. Procedure allways fails with an error at the end. (is in Chinese)
I tried QFIL but app can see the device only at EDL mode.
I tried to put another TWRP via Fastboot but with the order fastboot device says ...searching for devices. It cant see the phone when in bootloader mode. (yes a have installed all drivers including qualcom usb drivers, google drivers, generic android drivers etc.)
I tried some versions of YGDP tool (latest v.5.00) but fails with this error..

No. It stays here...
What drivers did you put in your windows, and how your device seems in device manager when is in fastboot mode before you install thw new rom?? Do you remember?? I have unistalled all drivers from my windows. i installed only Qualcomm_USB_Driver_V1.0 and Coolpad-150819-Setup from russian site that had the rom. But the only thing i see in device manager is..... Other devices/unknown device

i am trying to install those drivers as android adb interface. But windows says they are not compatible and didnt install them. Or you install them as android device instead of Android adb interface??

Nah......... Nothing seems to work. Time for the recycle bin i thing. The only app that sees the phone in fastboot mode is the YGDP Tool. But it says new bootloader error and stops the flashing procedure.

It's complicated to help you, I use google translate, and it does not translate right and it gets complicated to understand.

Trying to downgrade your firmware, bootloader refuses to boot, in some new version you canĀ“t downgrade by the usual way.

Try to install first only recovery and bootloader partitions, then if sucessful you can use fastboot again to flash boot, system and userdata cause maybe the other partitions are ready yet or also you will able to flash all the other partitions through YGDP.
