If you managed to get to bootloader try unlocking it, flashing custom recovery and then flash stock rom.

can you enter custom recovery? It seems this is not a proper Rom for your device, so download another TWRP backup and put it on sd card, go to twrp and do a full internal/system wipe, and restore the backup
Yes i can enter custom recovery, I have downloaded almost 4 roms and i am getting the same issue on all the roms but i can restore any backups from TWRP. The only issue i am facing is my phone is HTC desire 816v China Unicom and i am using it in India. I cannot receive text messages (SMS) in the first Sim Slot (CDMA). So i tried to install a new rom but i had no luck. Can you let me know a stable rom or stable rom backup ?
Thanks!

hi everyone. my htc desire 816 was running on lollipop 5.0.1(htc a5 dwg india version dual sim). it was rooted and bootloader unlocked and for rooting i had flashed cwm recovery... so everything was going fine. then i recieved update notification for marsh mallow (first step of which is of 68.2 mb). so i flashed stock recovery and downloaded the update.. but while installing i got red triangle error. i tried to install 2- 3 times but result was same. then i read one thread on our forum in which it was mentioned to flash the stock recovery which i recieved in 68.2 mb update file. i flashed the stock recovery then downloaded the ota update and it got install .. everything went well. but the device is stuck at bootscreen with green htc logo.. thats it.. now when i connect my device in fastboot mode its getting detected in my pc's device manager but not in adb devices. so i am not able to use adb commands....

Phone restarted and got stuck in Bootloop after flashing Custom ROM

I followed one post on Dev ROM on this forum.
I tried installing the Sence 7.0 ROM on HTC Desire 820 Dual Sim and it installed without any problems but at the end when it asks for Reboot, phone restarted and got stuck in Bootloop.
Could anyone please help me resolve this problem?
Your help will be really appreciated.

Try to make as: Tighten the two volume buttons and the power button when a black screen appears to hold the volume- button and power, smart mustget into in the loader in the boot loader to choose reboot (assuming that the system is not removed)
Return to stock ROM by the rebootRUU method and then upgrade to the latest MM ROM which has Sense 7 installed by default.

Can you get to fastboot? (phone off, hold power+volume down until it enters fastboot)
Yes, as bigsupersquid said:
Firstly switch off your phone if on
Then hold volume down and power button to go into bootloader mode
Go to fastboot
Connect phone to pc and then download twrp 3.0.x instead of 3.1.1 since it gives bootloops
Flash it and restart phone
Your phone will be running normally
