[AT&T HTC One (M7)] bzowk:
Hey Guys -

After being an iPhone fanboy for a while, i wanted a change so got an HTC One (M7 - AT&T) a few months ago. Since then, I've tried a couple of ROMS and liked ViperONE the best. Recently, I decided to completely redo my phone because:

- I had too much crap on my phone

- A new major ROM version (7) was released

- My signal strength seemed to be ~30% lower than usual at work and home - didn't know why

In hopes that the result would be the updated ROM with all other files/folders from the emulated SD gone, I downloaded the RUU I thought matched and applied it. Once done, I applied the new ViperONE 7.0 ROM for HTCOne then proceeded to root and get all apps installed and configured.

The next day, i found out that when I launched the phone app, it immediately quit. ARGH! I also can't receive calls. I wouldn't think this would be a ROM issue as the phone app would hopefully be the first thing they test. Therefore I am deciding to stick with the same ROM team since I like it so much.

So... this time around, I did a bit more research and am posting before doing anything to make sure I'm doing everything correctly or with the best chance of success. Below are details about my phone as well as the plan I currently have...

Proposed Steps to Fix / Re-flash

1. Back up everything on phone (done)

2. Download following: (done)

- Newest TWRP img

- Guru Reset 5.12.502.2

- Stock Firmware stock firmware 5.12.502.2 (Just in case)

- Newest ViperONE (7.0.1) ROM for M7

3. Copy Guru Reset 5.12.502.2 to phone's root and install via TWRP in Recovery

I've never used Guru Reset before so don't know what state the phone will be in afterwards. If prompted to keep my root, should I or should I really go ahead and start all over? Depending on what the result is after that, I'd then re-root if need be then go back into recovery and flash ViperONE ROM.

Is that a good plan? If there's anything else you think may be a good idea to also add in or try (especially anything that may have a chance of fixing the radio) would be great - Thanks!

PS: I've seen online that I'm not the only one who has a "purple haze" on my M7's camera. While doing all the above, any suggestions for how any fix may be applied or is it a hardware issue? Thanks!
