Bricked phone, Please help!

[Guest schecter]

Hi. For 2 days im trying to rescue my Coolpad 8297w. I tried to install recovery by apk, and i got brick. Its boot-loop actually and i dont know how to fix it. I tried to use coolpad download assistant and ygdp with stock rom but still nothing. When i tried first time flash with coolpad assistant and 4.4 rom it worked, flash was succesfully, but when i turned on phone nothing changed. After this i tried with 4.2 stock rom but after that flash wasnt working anymore, flash failed when first bar went to 100% and second didnt even get 1%. I had the same drivers like before so dont know why its not working. 

Please, give me some advices, i dont know that to do. I tried with different drivers, but something i have to do wrong :(

Sorry for my poor english

 

Edit: Im still trying, can someone tell me how to install this precisely: "Vcom_Driver_AutoInstall". Its by devices manage, but i dont know which files, because there are exe and inf files :X

 

PS. Im talking about this guide: http://www.modaco.com/topic/373530-guide-ygdp-tool-for-flashing-stock-42-44-roms/

You should install vcom driver. Install.exe for 32 bit windows, install64 for 64 bit windows. If you have win8 follow the guide for it.

 When I try to install installdrv64 then appears:

for 0.5s its correctly?

 

I was trying this guide before because i have w8 but i cant find out how to do this point : 11.Select to manually guide windows to the driver files (Win7 folder inside vcom folder).

 

I dont know which file i need to use to manual install.

when you see a message like "choose to install from a specific location" or "let me choose from my hd" or something similar guide windows to the win7 folder

Then i should choose "usb2ser_Win764" and install this driver for which option or for all of them?

Still nothing  :x and when i plug in into pc in fastboot mode is all the time losing connection, i cant even upgrade drivers in device menager, because its desappearing

[Guest mixanikosgr]

Try also:

Disable antivirus and firewall in the PC.

Use a USB port at the back of the PC.

Disconnect all the other USB devices connected to the PC.

Put the phone in recovery mode (press vol+ and power until the screen lights)

Connect to the PC
