HTC Desire 820S (Dual Sim) Bootloop issue. - Desire 820 Q&A, Help & Troubleshooting

Hello! I'm currently having bootloop issues with my HTC Desire 820S (Dual Sim).
I've tried to Factory Reset my phone from the HBOOT menu, but it starts the bootloop as soon as I press the 'Factory Reset' option. The same happens if I try RamDump or Recovery mode.
Any ideas on how I can fix it? I'll really appreciate all the help I can get. Thanks a lot in Advance.

Cannot update HTC desire 816 dual sim phone after rooting it

Hi I have unlocked bootloader in my htc desire 816 phone and then rooted it, i have a problem when ever my phone is out of charge and switched off and when i keep charging FAST boot screen is appearing (i mean screen where we have options as such as hboot fastboot recovery clear storage simlock etc) .
this is appearing even when i tried to factory reset it.
This is screen is appearing when i tried to update my phone with Android 6.0 yesterday .
Please help in this regard what steps i have to follow.

That's completely normal. The only way to disable fastboot start is to go back to stock.
It's booting to fastboot, because your bootloader is unlocked.

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.

Click to expand...
Click to collapse
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.

stuck at HTC logo screen and restarting ..
