[HTC 10 Questions & Answers] LaZiODROID:
UPDATE: it was impatience. I didn't wait long enough, staring at the green HTC logo. I let it go for a long time and now I see the welcome screen. I'm going to start all over.

Semi-noob here, needing some assistance. Can anyone help?

My HTC 10 is:

S-OFF

Bootloader unlocked (currently)

CID 11111111 (SuperCID)

MID 2PS650000

Was from Bell Mobility carrier (sim unlock performed)

Story (sorry for the long story, but want to provide as much detail as possible):

- I was on 2.41.666.3 (via the Bell Mobility RUU) since January, with the bootloader locked. I had TWRP installed, and root, and decided to update. The phone had been constantly offering to update OTA, and it was getting annoying, so I tried it. From what I can remember, it tried to start, but it rebooted the phone into TWRP. I assumed it wouldn't go because my phone had TWRP and root.

- So I then tried to flash the newest RUU I could find (which was 2PS6IMG_PERFUME_UHL_O80_SENSE90GP_MR_hTC_Asia_TW_3.16.709.15_Radio_2.0.U010241a@80125_88.12_F_release_525207_combined_signed_2_4 .zip), which I tried via renaming to 2PS6IMG.zip, and using SDcard/download mode method. It refused to install saying "FAIL10 RU_MODELID_FAIL modelid in android-info mismatched". OK so my MID doesn't match it - and I'm not sure if it's safe (or possible) to change the MID, so I decide to try a different RUU.

- So I move on to trying a "generic" exe RUU (which was RUU_PERFUME_WL_N70_SENSE80GP_MR_NA_Gen_Unlock_2.48.617.1.exe) and it worked just fine.

- I booted into it, tested phone call/data, all seemed good. But it wasn't "new" enough for me (of course!) so I decide to move forward, onto a custom ROM.

- So I unlocked the bootloader via HTCDEV, and flashed the latest TWRP, and decided on a ROM.

- I think this is where things went bad - I chose "LeeDrOiD_10_V5.2.1-R146-Stable.zip" and installed it via TWRP. I believe this is an OREO rom, and my phone was not on an Oreo base (so I think this is where things went wrong)

- The install finshed, and I rebooted. I saw the LeeDroid splash screen on bootup, but after a few seconds, the phone would just reboot. So I was in a bootloop. No problem - I will just RUU again, and try another.

- So I re-RUU'd the "RUU_PERFUME_WL_N70_SENSE80GP_MR_NA_Gen_Unlock_2.48.617.1.exe", and it went OK. BUT - I noticed I was not getting any cell signal any more. I guess I broke the radio somewhere...

- So I read some more - From what I understood, I could flash 3.16.617.2_FULL-WIPE_firmware.zip via TWRP to be on oreo-based firmware, then flash an Oreo rom or ruu to be back to normal.

- But 3.16.617.2_FULL-WIPE_firmware.zip would not flash in TWRP - it said "invalid zip file format".

- Then in desperation, I flashed to a very old RUU, just to start from scratch (RUU_PERFUME_WL_M60_SENSE80GP_NA_Gen_Unlock_1.96.617.20.exe). It flashed successfully, but when it boots, it is simply on the green HTC logo. i can do things like change the ringer/audio/alarm volume, and hold the power button to get Power Off or Reboot option. But that's it.

So this is where I am. Firstly, I'd like to get radio function back, and secondly, I'd like to know what I can do to get to the latest version of Oreo. Any ideas?

Any help would be appreciated.

Here is the info it currently gives me when I enter download mode:
