Anyone managed how to add LTE bands on sprint m8?

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.
Hello, does anyone who bought this phone knows if and what bands can the modem aggregate? i am thinking of buying one (redmi Note 8 or 8T depending on the price i can get) and i can't find what bands can the phone aggregate or if it even supports carrier aggregatiuon.
Yup, note 8 locked CA
Unlock Manual Use QPST and Qxdm to unlock CA

Hey
I'm facing an issue with QXDM
I wanted to enable 700MHz (B28) band as well as CA.
I bought the international variant of this phone, which claimed it had those bands and CA.
This is a dual sim with an additional SD card slot (so it has a total of 3 slots).
I'm trying to enable this band by editing the corresponding values with the one I generated with an app, but it didn't work, I can't get thoses to work.
Do you have any *working* tutorial for RN8, with Dual Sim card slot ?
Regards,

Hello folks, i need your help to unlock the band 20 of redmi K30 5G. Currently i have Chinese rom installed .
Is a way to unlock the band 20 ? I saw new Xiaomi MI 10, if you change the rom will enable the band 20 . ( in that case is a software limitation)
In our case ?
Thank you !
Nobody can help me ?

Any update? Id love to own this phone but need band 20 here in switzerland. Its the only one deactivated that i would need
People tried to unlock bands at the poco F1, but, there was no success, And people tried a lot
I found the possible files causing the restrictions on LTE and 5G bands, but I have no idea how to modify them to unlock bands.
In the policyman folder, the files:
- china_msim_restrictions.xml
- disable_nsa_mmwave_bands.xml
- lte_feature_restrictions.xml
regards

These files doesn't unlock B20 - this is hardware limitation. Bands are configured to nvitems but on 5G phones many things changed.
But could you please share to me your modem log file so i can list all hardware supported 4G bands to my cacombos.com website? I have here instruction how to get log file: https://mt-tech.fi/en/how-to-get-4g...phone/#Method_for_Qualcomm_Devices_after_2020 and you can send it to: https://cacombos.com/contribute . This help me understand what bands & combinations this device support.

If you change any ROMs from global to China and vice versa won't unlock the bands. This is locked down with hardware, not software. Older Qualcomm devices could unlock bands with Qualcomm tools/programs. This isn't the case with newer models.
