You are lucky, I recently almost bricked my phone, searched for hours and found it!
It is a chinese image, so be prepared to find your way through the menus and change it to english.
Camera does not work in this image, so you better have a backup of your stock ROM.
The ROM is available at http://u.115.com/file/f082f11464
and includes all these files, needed for a TPT flash.
To flash it you will need USDL_P726CV1.00.00, google for "v880_conversion_recovery" and you will find a package v880_conversion_recovery.zip, that
contains this flasher.
The cellphone must be in "download mode", you follow these steps:
1 - remove the battery
2 - press Vol + and Vol - simultaneously
3 - without releasing the buttons, plug in the USB cable
4 - wait for windows to find the device, i suggest you to keep Device Manager open and watching for any changes
5 - now you can release the buttons.
The flasher is in chinese, but after you open it there is a button, "English Version". click it, close the flasher and open it again.
Configure the flasher to connect to the right COM port, choose the option "Download", set the directory where the ROM is stored and click "Start All" to flash.

Thank you everyone
Edit:1 also i need a x850 complete system.img for tpt flashing any version would be great
Edit:2 Ok so i have got my hands on partition.mbn and partition_zte.mbn for the racer, im not sure what country or version these files are, i need the rest of the rom.
