[Verizon HTC One (M8)] TidusWulf:
I found a hboot flash of all firmware minus boot and recovery. flashed it, and I'm still getting no data. I also went back into diag just 1 min ago and loaded up DFS and sure enough my radios were back to the 3,4,7,13 you say they should be at. Is there a certain app or menu I need to open? because the very limited options that the Mobile Data is giving me (global, LTE/CDMA, LTE/GSM) are not giving me what I need, that's for damn sure.
[Verizon HTC One (M8)] piyushkohli97:
Did u do a stock recovery factory reset?

Also, is ur apn configured correctly?
[Verizon HTC One (M8)] TidusWulf:
I haven't flashed a stock recovery yet. that's a very last resort.

I didn't even think about APNs. I thought that was mostly to do with MMS. I will try that now and hopefully it fixes it and I'm just retarded.
[Verizon HTC One (M8)] cincon:
We are using here band 1/3/7/8/20 , what should i use for those bands?

i wrote with QXDM Nv 6828 and 6829 both----> 524485, correct?

but still i could not get LTE signal =(

who is going to help...
[Verizon HTC One (M8)] TidusWulf:
Honestly what's strangest for me is that I no longer get HSPA data either. It's all very strange...
[Verizon HTC One (M8)] piyushkohli97:
Which service are you connected to? 2g, 3g or 4g?
[Verizon HTC One (M8)] TidusWulf:
No idea. I don't have any data icon at all. Only the ? sim card (since it's a tmo sim in a vzw phone) and the signal bars. no 2g,3g,h,4g, or lte icons will show.
[Verizon HTC One (M8)] piyushkohli97:
Use DFS, qxdm never worked for me.
[Verizon HTC One (M8)] TidusWulf:
this sucks. I'm pretty sure my phone is never gonna get data again now. ;_;
[Verizon HTC One (M8)] piyushkohli97:
Did you try factory data reset?

Did you got apn configured?
[Verizon HTC One (M8)] TidusWulf:
I did a factory reset. I flashed a custom RUU, too. the next step is to flash a stock RUU with stock recovery, then do a factory reset. apparently that's somehow different for whatever reason. I had HSPA for all of one minute this morning, but I dunno. I'm wondering if Android 6.0 is the problem. it's so weird.
[Verizon HTC One (M8)] piyushkohli97:
What about the APNs pal, are u sure ur APNs are proper?
[Verizon HTC One (M8)] TidusWulf:
yeah, I made sure my APN is what it should be. (fast.t-mobile.com, etc.)

[Verizon HTC One (M8)] cincon:
and also nobody knows how fix it =)
[Verizon HTC One (M8)] sonnu0100:
I managed to change it via qpst . It is a bit risky to use that software . Amd have manually calculate and put the hex code in 6829 in qpst . But after enabling band 3, 40 there is no lte signal on my phone . I think it cant ve enabled only via software the m8 hardware must also support it .
[Verizon HTC One (M8)] cincon:
me too..but just few seconds look LTE after that turns H+, i think that problem is 6829

which bands did u active it?
[Verizon HTC One (M8)] gamekill:
OK so it worked. Turns out it was the service provider's fault afterall. Even though my LTE plan was supposedly on, someone at the company blocked it on my line. I went to a service center and they realized this and fixed their mistake. I apologize for bugging you with this.

So.. working for me also. Voted at the OP.
[Verizon HTC One (M8)] piyushkohli97:
Great!!
[Verizon HTC One (M8)] piyushkohli97:
If the phone has hardware support for band 20 then on unlocking with dfs the phone will get lte via band 20......all you can do is try.
[Verizon HTC One (M8)] cincon:
That's why i told that. Because some people said band 20 is ok with verizon htc... I dont bealive that.. Because verizon does not support band 20!
[Verizon HTC One (M8)] piyushkohli97:
If ppl hv got band 20 working on their verizon m8 that means something, i hv unlocked all the bamds that ondian telecos are using and believe me i did never used to get 4g before this. Just take a gander at the bands available in india, i highly doubt any of the band will be common with that of verizon's.
[Verizon HTC One (M8)] cincon:
i did LTE band 3 actived with DFS just with 6828,(6829 is blocked)..because verizon support 1800 mHZ band 3, that's why i was able to active this band..i am sure i can not active band 8 and band 20..(because verizon does not support as hardware)

If your M8X has Qualcomm processor, maybe yes.

It works nifty on M8 and M9 in US.

[Verizon HTC One (M8)] piyushkohli97:
Can you elaborate? As the links posted by you are giving a 404 error.
[Verizon HTC One (M8)] piyushkohli97:
​

Maybe the hardware support is not present for the bands you are trying to write.
[Verizon HTC One (M8)] ska1v3r:
How can I check it?
[Verizon HTC One (M8)] piyushkohli97:
The only way you can check is by verifying if your phone connects to 4g after bands modification.

You can unlock the bands without bootloader unlock..... But if u need bootloader unlock, custom ROM, etc. U need to shell out 25 dollars, there is no other way.

[Verizon HTC One (M8)] andybones:

[Verizon HTC One (M8)] andybones:
It's against the rules, however to post the same question like that.

Why not get the unlocked variant?
[Verizon HTC One (M8)] jazzdglass:
Unlocked is more expensive. And I only see detailed GUIDE to unlock all LTE bands for cdma variants, so for me, it's either verizon or Sprint....

[Verizon HTC One (M8)] sonnu0100:
The firmware conatins the original radio with stock values. Reflash the marshmallow firmware (modified) with boot and recovery removed . Flash twice frimware this time . Then flash a stock marshmallow ruu. Dfs worked in mine case .

Try this one too in phone.

Hit Thanks , if Somebody helps you..?
[Verizon HTC One (M8)] marum:
An update: finally got radio working plus enabled some additional 3g bands which gave me HSDPAP.

A solution was to remember an "original" band list then disable some extra CDMA WCDMA I added and completely restore LTE band list to be (25,26,41). A problem I think was enabling WCDMA III (DCS 1800) & WCDMA VIII (GSM 900). Radio stucks if these are enabled. So for anyone using DFS I suggest to do enable bands one by one and test(reboot) for each new band if a radio is still able to connect network. If not disable that band, then repeat the same with other bands.

A conclusion is that this band list won't be restored nor altered by flashing stock firmwares and roms and can only be altered with special tools such as DFS.

Does anyone has a clean understanding and could explain technically about where are these values stored?

Is this a PRL list ?

I have a US imported factory unlocked HTC One M8(T Mobile) which I purchased from EBay. It did not come with 4G. It is rooted, has s-off, unlocked bootloader with twrp recovery. I have installed Wolla v6.2 rom on it (Android 6.0.1).

I tried the technique mentioned by the OP to put the phone in diag mode (through adb) and I was able to do it only once. Then from the DFS tool I checked it initally had band 4 and 17 checked. I added the band 40 for Jio and restarted the phone but still I don't get the Jio 4G signal. Even airtel 4G signal doesn't come.

Again I am trying to connect to diag mode but its not working. The phone disconnects after entering the command to enable diag mode.

So I have two questions:

1. Which bands should I add to get 4G for airtel and Jio?

2. what should I do to enable diag mode? Is rom the cause for this? Since I have to disable and re-enable debugging mode everytime to run adb shell.

Any help appreciated. Thanks!
