So I have found the stock OTA update to 2.22.771.5 from Three UK, extracted the radio.img from the firmware zip and flashed using the ADB method described in the OP.

When the phone reboots, I get no signal and if I check the baseband info through about phone, I get 'Baseband Version Unknown' so I flashed the backup of the original and now I am back to 1.21.213347A1.19_2G_20.63.4196.01L_F (radio included in 3.28.401.6)

Am I right in thinking the stock radio included in the Three UK 2.22.771.5 firmware is not compatible with the 3.28.401.6 firmware I flashed in order to get android 4.4.4?

If anyone knows how I can get this radio to work I will sort beer tokens :D

Thanks in advanced.

You should be able to go here http://xdaforums.com/htc-one-m8/general/vomerguides-m8-bootldr-unlock-s-off-t2800727 and DL a 2.22.x fw and extract radio.img and flash in fastboot.

I have noticed the same thing the last few days on Rogers - LTE is really slow in some bad signal areas. But I haven't tried downgrading the radio yet.
[One (M8) Android Development] JohnM109R:

That don't sound like a radio issue to me.are you still running cyanogenmod?

Did you have the problem running stock?
[One (M8) Android Development] sameer1807:
Hi Guys,

So i've tried numerous times to post on rom threads for the M8 but ive gotten no help regarding the issue. then i saw that some of the replies on this thread were similar to the problems i have after upgrading my at&t m8's fw to the latest one (1.7). So basically, in some areas, although i am connected to LTE, google based apps (mainly google maps, google search, and chrome) will not load. the only way i currently have access to the internet when the internet dies is to use another browser. even with this fix, i cannot use google now or maps to search. i am on the 3.19.000... and have the 1.21...31147a1 radio but cannot figure out why google related apps quit loading. also, i have ran multiple speed tests. i notice that when the connection issue occurs, up speed is nonexistent. don't know how to fix my phone. please help
[One (M8) Android Development] trajik78:
Happened on all 3 M8s I've been through. All were stock. I figured I'd try CyanogenMod since it was running 4.4.4....mainly the rebooting is nuts...happens when it goes in and out of WiFi.

Either copy the file you want flashed to root of your external SD card and rename it to just 0P6BIMG.zip (that's a leading zero, not letter O),

or open command prompt, then do the fastboot rebootRUU , then fastboot flash zip 0P6BIMG.zip and finally fastboot reboot-bootloader.

Also, is your device overclocked or undervolted?

No worries. I know flashing a rom would not help. I looked at the script used for the radio update which is updating the mmcblk0p20 partition. It could be a partition boundary issue. Perhaps different models have different boundaries. Hopefully I get this resolved before Monday. This would have been a 5minute fix if I have access to a pc. But I guess I need more creative options without a pc.

T-mobile network on a Verizon HTC one M8

Verizon M8 variant on T-Mobile network

IT seems quite a few people have this problem where the network will not stay connected or it will show you have a bar or two but you cannot connect to any data and calls end as soon as you click on call. Put it in airplane mode and then take it out usually fixes this.

Using the Verizon stock ROM I was unable to get data to work more than 5 minutes. Running 4.4.4 I was unable to change the APN's so I downgraded to 4.4.2 which let me add the TMO APN, however it kept reverting back to CDMA and I could not get SMS and calls kept dropping.

I had to install ViperOneM8 3.1.0 with 4.4.4 and it works pretty good. It does not switch to CDMA and likes TMO. I still have the issue that the network shows 1-2 bars but I have no data connection and cannot make calls. I tried flashing the latest TMO radio but the phone didn't like it, kept rebooting after unlocking the home screen.

Anyone have a fix?
