[Q] OTA update failed topic

Hi,

This morning, I received the OTA update for Android L. I downloaded it but when I tried to install it, at about 2/3 minutes after it started, the little "!" icon turned red and my phone restarted. I tried an other time and it failed again..

A couple of months ago, I've installed on my device the Stock ROM (odexed version) and the Stock Recovery for Android 4.4.2 (for the HTC One M8, obviously). Everything went well. Then, I was able to update to 4.4.3 and 4.4.4 thanks to the OTA updates without any issues.

How can I install this new OTA update ?

For your information, on my bootloader, I can read "Software status: Modified", "Relocked" and "S-OFF". My CID is 11111111.

Any help is appreciated.

Thanks
