Flash via recovery:
1. Download the flashable zip above and store it in your Internal or External SD card
1. Boot your phone into recovery (I used TWRP)
2. Flash the zip you downloaded
3. Wipe Dalvik/Cache
4. Reboot System

Fiash via adb:
1. Download the radio.img above
2. Put the radio.img file into your ADB folder
3. Open up command prompt and copy and paste the EXACT lines
4. adb push radio.img /storage/sdcard0/radio.img
5. adb shell
5. su
6. dd if=/storage/sdcard0/radio.img of=/dev/block/mmcblk0p20
7. adb reboot

To Backup your Radio:
1, adb shell
2. su (if needed to get a #)
3, dd if=/dev/block/mmcblk0p20 of=/sdcard/mmcblk0p20
4. exit
5. You'll find the radio image on the internal sd card. rename it to radio.img if you'd like

Some advice for people with the ASIAN version of the HTC One M8 (aka 2.5 Ghz Krait phones).

I have tested the following radio's and they do not work: ATT, T-mobile, WWE, GPE. I have not tested the dev. edition radio yet. My phone has S-off and Super CID.

When you flash any of the above radios your phone will boot fine but it wont connect to a tower. After five minutes of trying to connect, the phone automatically reboots. To restore your phone you have to reflash the Taiwan radio (HTC__621 / 1.54.709.4).

If anyone with an Asian edition phone wants to double check my experiment, feel free to. The risk of damage to your phone is nil.

Will flashing the AT&T radio open up the missing bands on the T-Mobile M8?

Sent from my HTC One_M8 using XDA Premium 4 mobile app

I flashed the AT&T radio on my T-Mobile M8 and got excellent results. On the T-Mobile Radio I was getting very spotty lte at my house, but since flashing the AT&T radio I have not experienced that spotty signal and data speed.
