I think you have to wait for PC hisuite's update option to show an 'other firmware' link with an option to a rollback firmware.

Did you unroot before upgrading, if not then it's all your fault
Still, it's possible to get out of it.
Let's start from the simplest and move on to the complex.
Simplest is to boot into recovery (custom or twrp/cwm) and wipe cache and dalvik cache. If you did not unroot before upgrading then no need to do the above.
If that does not work, you may have to use adb to flash images to your phone in fastboot mode.
Please let me know what was your phone's root state at the time of update so we can move forward with complex stuff.
my phone signed is 4x che -tlooh ?does any one have the same with me?
