I have HTC U11+ TW version. Ever since I got the Pie update, my phone is freezing a lot. I need to force restart it 10+ times a day. I tried factory reset, clear cache, etc. Nothing works. I did not have any experience with flashing, but I have been reading a lot. I have my bootloader unlocked with S-ON.
My current build number is 2.15.709.1, since I wanted to downgrade, I tried flashing stock image HTC_U11+_TW_1.24.709.999_Images_OTA using fastboot (no TWRP). My phone went into a bootloop when I did that. I think this is because I can only flash an image with the same build number? Anyway, I flashed a HTC_U11+_TW_2.15.709.1_Images_OTA image and my phone is back to where it was, Android Pie (no bootloop), but still freezing a lot.
I found the HTC_DevInfo_Tool.zip tool on this thread https://forum.xda-developers.com/u11/how-to/guide-downgrade-htc-u11-oreo-to-nougat-t3754481, but I am not sure if it will work on my phone.
Can someone advise what should I do to downgrade? Also did anyone face a similar problem after the update?
