I received a push notice to download and install Sprint HTC One (M8) Software Update 4.25.651.14 which was released on 4/9/15 with Wi-Fi Calling enhancements. My phone is rooted. I use Super SU Pro. I use TWRP (Sprint) for my custom recovery. Never had any problems with applying previous OTA updates. I connect via ADB shell and flash stock recovery for version 4.20.651.10 currently installed on my phone. I use One_M8_All-In-One_Kit_v2.0 to perform the shell commands.

I apply the OTA update in the stock recovery from my phone and everything looks good, but when the phone restarts it gets frozen in the white "splash" screen where it says "HTC One powered by Android". I waited over 15 minutes and nothing happened. I was able to recover my phone by booting into the bootloader and flashing TWRP then restoring my nandroid. I could see in the bootloader screen that the firmware was updated to the latest version.

Does anyone know what is causing the phone to freeze after the firmware is updated and the system restarts?

I tried to manually install the OTA zip file using TWRP from my phone to update the software. I selected the Zip file saved in the phone's root folder and used TWRP to apply the update, but got an error message that it "failed".

Does anyone know what steps are necessary to manually apply the OTA software update?
