[Q] Failing to flash stock recovery
I am running a stock ROM software number 1.29.708.4, Android version 4.1.2
I have successfully rooted my HTC ONE to use some Superuser features but never installed an alternative ROM. Now the OTA update 4.2.2 is coming in, which I would like to install. I learned that I cannot install OTA updates on an unlocked phone,so I tried following this guide here
to re-lock the phone and then flash it again to install the OTA.
So my first question: Isn't it easier to simply flash the target version of the OTA? Is there a way to get to the 400MB large update and install it with the current bootloader/recovery? The software update that is being downloaded is version 2.24.708.4
So according to the instruction linked above, I installed fastboot, HTC Sync and relocked the bootloader successfully. Then I downloaded the RUU EXE file here and tried to start it while the phone was in the USB fastboot, but the RUU starts and then silently dies without ever showing any activity. I assume this is not normal, but I do not know what and how to change there.
The other thing that makes me think is I read that I need to "Flash a stock recovery". Is that the same as flashing a 1GB large RUU? Or is there a simpler way to just flash the recovery software? If so, where do I get that?
