Why I amn't able to update to 5.1.1 ?

Hi guys I need your help.
I have M9 and first time I had installed unlocked/developer version of firmware 1.32.617.30 and performed full installation of insertcoin ROM ICE 3.1.2 and it installed successfully but didn't boot . It was stucked on starting apps screen then it rebooted and continiued optimizing apps from 0 to 158 and repeated this cycle all the time . Then I installed firmware 2.10.401.1 (read that it was based on latest firmware ) but the resuilt was the same . Now I have installed lollipop 5.0.2 Insertcoin 2.1.6 and it works well but why amn't I able to update it to 5.1.1 ? am I doing something wrong ? I also tried to install Android Revolution HD rom, and other 5.1.1 based roms but problem still remains.

HTC One M8 Stock rooted ROM

Hello, i just get update request on my rooted HTC One M8 (global). I was unable to install 6.0 android with TWMP.
Does any one know stock rooted android 6.0 rom, that i can install with TWMP ?
Many thanks

OTA will not install by TWRP. And a flashable MM ROm is probably not what you want; at least not if you want the proper MM firmware and future OTA updates.
You need the stock (never rooted) Lollipop ROM, and corresponding stock recovery, in order to properly update to MM.
