Lenovo Lemon 3 (K32C36) cant boot in recovery mode.

Need help please, before 2 days i try to install this rom PAC-ROM but when i go step by step as the description, now i got a big problem i think... my phone cant boot at recovery mode.

steps i followed:
1 ) i flashed a Rooted ROM based on official ROM from baidu site
2) i installed TWRP as shown there --> http://ift.tt/1Elc4TZ
3) i go step by step as shown there ---> http://ift.tt/2c9DZMf
4) i did backup only system files
5) i format/wipe everything
then when i try to install the new ROM from SD it says me that fail to mount /data
i try to format again to wipe again and again but the same, cant install and cant mount nothing
so i try to restore the system backup i did before then my phone boot normally in previous rooted ROM but now i cant open recovery mode on my phone and cant flash nothing, because adb cant boot in bootloader mode...

Please and help how to recover my phone, because now is in Chinese ROM and nothing work properly (no google services, no playstore, no keyboards, etc)

Thank You

After this i try to restore the system that i did back up before and my phone boot with the last ROM i got before (K32c36 S034) and rooted but when i try to boot in recovery mode its impossible.....
i have tried everything with hard reset with adb with qpts but nothing...

when i press "recovery" just a black screen appears and i have to long press power button
