So after spending several hours figuring out and successfully switching my M8 to GPE i found out that my carrier does not support the correct frequencies to allow me to use LTE (carrier is sasktel in canada) my carrier uses 1700/2100
All major carriers (Bell, MTS, Rogers, SaskTel, Telus) are using AWS Band 4 on 1700/2100

is there any way i can flash just the radio on my now stock GPE and still have the rest remain as is on stock 4.4.4?
other question is would it be possible or rather how difficult would it be to go back to fresh out of the box status ie: back to the sense stuff if i cant use just the correct radio

What model HTC?
I assume your S-off if you've fully converted to GPE ?
Search "radio collection for HTC one m8" in your browser and you can also search how to go back to stock from GPE conversion.
yeah i am S-off and currently using the ATT 1.16 radio i found in the radio thread here but that does not get me to the LTE i tried a radio.img from a bell firmware pack but i didn't get any service when i flashed it so went back to the ATT one
it is an HTC one M8 with superCID but the original CID is SASKT001

"Fresh out of the box"?
You did make a nandroid before you modded anything LIKE IT SAYS ON ANY ROM OR MOD THREAD ON THIS SITE IN STEP #1, right?
My lesson to you is:
Read and follow instructions. They are there for a reason.
Good luck with your issue.
I'm not joking when I say I hope you get it fixed.
But seriously, protect yourself. That's what backups do.
If you screw something up, you have something to go back to.
This is said in EVERY thread. For a reason.

You can flash any radio you want to test/use and if in your opinion it works for you than keep running it

Hi everyone,
This is my first post on XDA and i'm actually thrilled.
So I have the Taiwanese unlocked model of the HTC One (M8) and I'm thinking over fully converting it to a GPE with the famous RUU.
I tried searching the forums but couldn't find a strict answer for my issue: If I fully convert my device, I know this means the radio image will also change to the stock one of the GPE version.
What does it mean? Will I lose signal because this is a different radio image than the Asian one? Do I have to change the radio image after installing the RUU.zip?
I'm fairly new to modifying my devices so take it easy on me.
THANK YOU SO MUCH IN ADVANCE.
Nimi.
If it's anything like the regular M8, you can just reflash the radio of your choice.

Yes, It is anything like the regular GSM M8, just the CPU runs at 2.5GHZ rather than 2.3 on US models, and of course it supports different bands.
So, I do everything just like the tutorials say and after im finished I can reflash the Taiwanese radio for example? Will I still get OTA updates?
Thanks!
You should be able to. But you may want to wait until someone with the Asian version can confirm. If you want to test it out, flash the 4.4.3 GPE ruu and see if you get the 4.4.4 OTA.

Sounds like a good idea, Thanks!
Anyone here with the Asian model that has converted to GPE?
Please.
UP!
Please, Anyone else can help here..?
Thanks!

I have Asian version. And I have rooted to convert to GPE. Everytime I install the GPE rom or OTA update. I always have to flash the asian radio so that I will get signal. I wish there was a way such that OTA will install and know that an Asian radio is required; or maybe something that will prevent my radio from being overwritten.
About the question if you'll get OTA updates automatically, I remember you have to modify you CID or MID or something. You will have to look up for that...
I have the Asian model as well, I converted over and placed the asian radio in the ruu zip before flashing, and now whenever i get an ota it doesnt change the radio
Hi all. I have a Telus One M8 that i recently converted to GPE using the non rooted GPE 4.4.4 RUU. Since converting I have noticed poor LTE reception. I have done some digging and found out that the GPE M8 does not support the 1700Mhz bands. Unfortunately Telus uses 1700Mhz for much of their LTE coverage. To fix this it should be as easy as flashing the correct Telus supported radio, correct? In the process of converting I changed the CID to GOOGL001 in order to receive the upcoming 5.0 update. In order to flash a different radio on the GPE RUU I will have to SuperCID? Which will then not allow me to take the 5.0 OTA update (most likely)? Just want to make sure I am correct in that I will have to choose between a Radio img that supports 1700mhz, or being able to accept the 5.0 OTA update.
Also, once the GPE RUU was flashed, do I have to go back and "fastboot oem unlock" the bootloader, or does it stay unlocked? Currently when I boot into fastboot the pink banner at the top says unlocked, I just want to make sure im not needlessly wiping my data.
I have tried searching (both in the GPE RUU thread, and the Canadian thread), but everytime I search within a thread I get "Sorry - no matches. Please try some different terms." even on terms that i know would come up in a search
Thanks for the Help!
Hello. I have a AT&T branded HTC One M8. No longer with ATT , the device is unlocked and being currently used with T-Mobile. Everything works fine. I went back to KitKat since not a big fan of lollipop since couldn't get battery life to be as excellent as KK. I did the 4.4.4 RUU for ATT and flash CM11 and everything worked perfectly, except signal. The signal drops so much to where in places that I normally had 4G LTE in I would drop to emergency calls only. But only going to kitkat. Whenever I was on Lollipop my signal was perfect, I'd use the latest ATT RUU for M8, then go to somewhere like LeeDroid. So after that rant, Can I use the T-Mobile RUU, or could someone point out a specific radio that I could use with Kitkat on T-Mobile network to where signal ought to work?
I would suggest the T-Mob RUU for best performance on the T-Mob network.
You'll need s-off, and then change to the T-Mob CID and MID to run the T-Mob RUU. Also, no need to relock the bootloader to RUU once you've done s-off.

Do I still need to if I'm Super CID? Also currently on Skydragon, used on of their modified firmware for T-Mobile. Seems to be working good. But still suggest to go ahead with what you stated?

If you are on the Lollipop T-Mob US firmware and Skydragon, you should be good to go. Do you have any signal issues with this setup?
To answer your CID questions (just as FYI, or in case you end up wanting to run T-Mob RUU), SuperCID will satisfy (pass) the CID check. But you still would need to change to the T-Mob MID (model ID). MID is a separate check from CID. You need to pass both to run the RUU.

Alrighty! Thanks for the MID info. My signal seems to be a lot better. I always was on HSPA+ with full bars, now getting around 2-3 bars of LTE. So cant complain about that since I live a little outside of town. Thank you for you assistance!
I want to install CM13 on my M8, but before I do, I need to upgrade to mm baseband. I'm not sure which version to download, though since my m8 is att I assume GPE would be compatible, since they are both gsm. following the link in this thread did not work, Dead link.
http://forum.xda-developers.com/showpost.php?p=66760703&postcount=1270
Can anyone tell me if gpe baseband will be compatible, and link to a download for me?

You should use the baseband that supports the bands needed for your carrier (AT&T?). GPE baseband is best suited for T-Mobile.
If you are on the AT&T network, just flash the RUU intended for your AT&T M8 to update the baseband. RUU will wipe phone, so backup accordingly before RUU.
I'm on metro pcs, a subsidiary of T-Mobile. so then gpe should work, right?
Hello I have a T-Mobile M8, using it in India. It does not support any Indian LTE bands. I am S-On, rooted and have installed LOS 14.1. The CID shows as T-Mobile. Is there a way to change the configuration of the phone to support LTE bands 3 or 40? Alternately can I add these bands to the device? I have read posts mentioning changing to superCID and possibly changing MID, then flashing a new modem. I am not sure what is the right procedure. If possible I would like to keep S-On. Thank you.

You can't do any of those things (SuperCID, change MID, flash radio baseband) with s-on. And you can only get s-off with sunshine ($25 USD). Additionally, getting LTE to work on this device (for M8 version not intended for your region/carrier) is tricky. I've seen a lot of folks fail to get LTE even after s-off, proper bands enabled, etc. So paying for sunshine s-off may end up being a waste of money.
If you want LTE service, the safest bet is to get a device/version intended for your region and carrier.
Thank you very much for this clarification.
