Trying to recover M8 that suddenly stopped allow WiFI/Mobile Signal

I have a barely functioning M8 and I could really do with some help.

A friend gave me his M8 a few weeks ago, the M8 would not boot. It was getting stuck on the boot animation. From what I could tell, I think the device had been interrupted during an update.

The M8 is Europe model, with MM installed. Bootloader was unlocked at HTC.com but is still S-ON. CID is HTC__001 and MID is 0P6B10000

I installed a custom recovery and flashed the latest ARHD. Finally the device booted fine and showed the correct software/baseband etc. in hboot and settings/about phone. Made test calls etc. it worked fine.

A couple of weeks later the guy is back to me saying the phone suddenly stopped sending/receiving signals, wifi no longer turns on and the phone will not acknowledge any SIM that is inserted.

First look shows the baseband, in settings/about phone, now shows "unknown". But booting to the hboot shows the correct radio version.

I went searching XDA/the internet for the MM radio.img but was never able to find it.

So next I looked for the Europe MM RUU, I needed to ensure that the radio was repaired, which I apparently found at this url:
Code:

http://ift.tt/1Y0Fg7L
it has a file called 0P6BIMG_M8_UL_M60_SENSE70_MR_HTC_Europe_6.12.401.4 _Radio_1.29.214500021.12G_20.72.4196t.01_release_4 64360_signed.zip

Now I have come across several XDA threads that say this file show be renamed to 0P6BIMG.zip put it on the root of the SD card and then boot to hboot where it will automatically find and install it. But with this file, when doing that it says image fail press power to reboot and never installs the file.

Next I came across an XDA thread that said I need to boot the phone into RUU mode and use htc_fastboot to flash the file, having renamed it to RUU.zip. but despite this being a 1.6Gb file it is detected as 53Mb by fastboot and again fails saying the file is corrupt.

I downloaded the file several times and no matter which method I us, it is the same result it will not flash the RUU. I have found a different hoster with the same file, same end result.

I need to fix this poor M8 and at this point I am out of ideas. Please, if any one can offer some advice on fixing this thing, I would appreciate it.
