So a big thank you all for everything you guys share with the rest of us!
This is the first time I couldn't find a solution to my problem, and i'm hoping at least someone out there will have the experience to give me some advice.
I've converted my HTC One M8 from Sense to Google Play Edition.
I used the RUU, so my M8 GPE is unrooted with stock recovery.
It's working beautifully and i have no intention of reverting to Sense.
But i am facing a problem with the radio.
It doesn't work, i'm not getting any signal at all.
I learned the hard way that the radio that comes with the GPE is incompatible with the Malaysian telcos.
I understand that the Taiwanese radio is compatible with the local telcos, but i dont want the phone rooted and i'm worried the only way i can get the radios working again is to root the phone.
Listed in order of preference, I'm guessing my options are;
1. Some amazing bro helps me get the radios working without rooting or reverting to Sense ROM.
2. Rooting my GPE to flash the Taiwanese radio to fix it.
3. Revering to Sense.
