Anyone managed how to add LTE bands on sprint m8?
i've tried almost everythuing , but maybe i'm doing something wrong?
i have S-on, bootloader unlocked , rooted stock rom
i calculated NV value with qualcomm nv calculator and used QXDM proffesional , also added "telephony.lteOnGsmDevice" in build.prop ... but still nothing?
i need to add europe lte bands 3(1800mhz) ,20 (800mhz)
bump?

hii, i am using Lee droid rom 7.4.2 with elemental kernel 4.xx for 2 months and all is working fine but recently i have changed my network to Zong Telecom here in Pakistan which is a subsidiary to china mobile telecom and i purchased its 4g LTE enabled sim card and yes i am in coverage area as well but when i go into settings and select 2g/3g/4g auto i do not get 4g signals and it stays to only H. it means my phone is not getting 4g signal while 3g is working fine... so i went to dialer and entered *#*#4636#*#* and in phone info i changed it to LTE only manually. and after few seconds all network dropped and i am getting zero signal..... i am afraid that this problem is due to my custom rom or custom kernel because i am getting 4g signals in my galaxy s5 .... so any idea what to do please?? any fix?????
Note: Zong telecom uses LTE FDD band 3 @ 1800 Mhz which our M8 supports... so no problem here as well.

Specific band support depends on what variant (CID). Are you saying that you know your CID variant supports LTE Band 3? Otherwise, it may not.
Check your APN. Carriers sometimes use a different APN for LTE.
Have you tried the SIM in another phone to verify LTE works on that phone?

CID or Carrier ID is the carrier or region version of the phone. It has nothing to do with the ROM, and can only be changed with s-off.
To determine your CID, do adb getvar all. Don't post your IMEI or serial number, if you post the getvar output.
You can also try a CID app, but I think these sometimes are wrong; and adb getvar all is the most accurate way.

That version should support LTE Band 3. I would try the SIM in another phone, and see if that phone gets LTE. Could be a problem with the SIM or the account.

Yes i have the exact same question,,, can we do this?? because non of the custom roms are supporting 4G even after manually updating the apns... any idea please?
i think you have to mess with the processor NV value or something.There is a unlock LTE bands thread here somewhere.It only unlocks LTE bands for Qualcomm based phones.Doesn't not add new bands that were not there to begin with but just unlocks them.LTE Apn's won't work unless the band is avaliable, you will just get HSPA or HSPA+.Note 4 snapdragon does have band 3 support, so you're in luck but the process is very risky as it involves editing the heart of your device.I was about to do it but it was too risky lol.Lots of people have had success with the unlocking, notiably Samsung users.
Hi,
I have Bell HTC M8 and m trying to unlock LTE bands .
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
Followed all the steps to write RF values.But the RF values reset to default.Read it a few places that it could be coz of the rom(currenlty running viperon 5.0.3) having NV lock .

Your post says Bell M8, but your signature says Sprint One (might mean the old M7?).
I've only seen the mod for changing NV values (to unlock bands) work on the "CDMA" M8 version Sprint and Verizon. The mod doesn't work (at least I haven't seen anyone get it to work) on other M8 versions, the NV values are locked regardless of the ROM. And I believe Bell is a GSM carrier, and would not be the CDMA variant?

Hi ,
Yeah mine is Bell M8 .The instruction never mentioned anything related to phone been only CDMA .Read a few places ever since kitkat the NV has been locked .

Those instructions you linked aren't device specific (and also from the Samsung Galaxy S5 forum section), and can't be depended on to convey all the M8 device specific nuances and details.
There is a similar modding guide in this (M8) section, but again the original source is not specific to the M8. And its unclear whether the OP even tested it on an M8: http://forum.xda-developers.com/htc-one-m8/general/unlock-bands-qualcomm-device-phone-t2880239
If you look through the subsequent posts, you will see multiple failure reports on GSM M8 versions, and the only reports of success on CDMA (Verizon, Sprint) versions.

Hi.
I need some help to change radio baseband on my m8 (0P6B130) so LTE/4G works with Telenor Norway ( https://www.frequencycheck.com/carriers/telenor-norway ).
it's s-off and cid 11111111
currently running: RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4
have tried this rom also, without getting LTE/4G working: 0P6BIMG_M8_UL_M60_SENSE70_MR_HTC_Europe_6.12.401.4_Radio_1.29.214500021.12G_20.72.4196t.01_release_464360_signed
ive found this: https://forum.xda-developers.com/showthread.php?t=2736921
but not sure what image will work for me, if any.
if possible i have another m8 (OP6B100) working with LTE/4G, if there is a way to read/save radio from that one and move to my new phone?
What LTE band(s) does your carrier use?
3G works okay? Or how about 2G data?
both 2g and 3g working 100%, im only missing working LTE/4G.
as far i figured out my carrier Telenor Norway use B3 B7 and B20 for LTE/4G.
but i can not figure out what radio that supports those bands and to try out

According to these specs, the Euro version should support those bands (1800, 2600, 800 MHz respectively). Which would go along with the statement that you have a model OP6B100 which as working LTE. But it doesn't explain why Euro RUU 6.12.401.4 doesn't give you working LTE.
Does the APN on the working (LTE) M8 match what you have on the other one?
the one im missing lte on is a 0P6B130 as statet, its my old one that is OP6B100 that have working lte.
apn match, and verified with settings off carrier website

I understand that already. All these phones are the same in hardware, the band support is (supposedly) determined in the radio baseband firmware. What I'm saying, is that one you flashed the 0P6B130 device with the Euro RUU 6.12.401.4, it should (in theory, at least) have the same band support as the OP6B100 (Euro) device.
However, we've seen this before, where M8 devices have been properly "fully converted" to another region/version, but will still not get LTE service in that region. We've seen this a number of times, and I have not seen any good explanation, and unfortunately, no solution.
thats what i thought after a few days googling, and reading around in here too.
can it have been some fault in flashing of radio even it said right radio version in hboot and android?
is there a rom for just flashing radio from the 6.12.401.4 RUU ?
tried to make backup of radio on OP6B100 from adb shell, but its not rooted so that went nowhere
