[Completed] Enable LTE bands problems with S3 I747 - XDA Assist

Hi there,
I am trying to enable more LTE bands in my S3 i747 con Andorid 4.4.2 becasue I am in Europe right now.
Regarding the specs, this phone can connect to LTE bands B3 B4 B7 B17 and B20, but now I just can set up to B4 and B17 through dialing *#2263#.
I am able to change the values in NV item 6828 in the processor Qualcomm MSM8260A but when I reboot the phone, the values came back to the previous ones.
Do you guys have any clue about what is changing, kernel or rom, the values back?
Thank you so much!!

[Q][GT S-7562L] Help with frequency bands

Hello everyone,
This is my first post and as I can not ask @abhi922 on his thread (http://forum.xda-developers.com/showthread.php?p=49779385) I am going to do it by this one.
I own a Samsung Galaxy S Duos but it is the Latin American version (GT S-7562L). Both devices are exactly the same except for their frequency bands. While S-7562 version 3G HSDPA frequencies are 900 / 2100, the S-7562L frequencies for 3G HSDPA are 850 / 1900. Is there any possibility to change it?
My final goal is to install Cosmic ROM on my device but as I know it is not possible due to this limitation.
PD: If anyone knows how to do this or what can I do, answers are welcome!
Thanks for your time

Frequencies are hardware based. No way to change it

Thanks for your quick response!!..
Now I want to know if there is any way to make @abhi922's ROM work on my device. If I am not wrong and my understanding is correct it depends on Kernel. Just having a compatible Kernel could make the ROM works without network problems?

[Q] any way to enable WCDMA 850 1900 band on lg g pro 2 D83810b

Hello , developers , Please help !!
i have lg g pro 2 D83810b version , it natively support below basebands
GSM: 850 900 1800 1900
HSDPA: 900 2100
LTE: 800 1800 2600
however my network provides 850/1900 HSDPA signals ,
is there any way to change this baseband by flashing Radio modem.bin in its KDZ , i am trying to find a way so that i can flash F350S modem in the D83810B so that it can use those signals ,
P.S: Help for Help
Hi, were you able to get it to work ? stuck on 2g here :crying:
the phone isn't equipped to handle those frequencies. i don't think it's possible to do anything to make it work on 850/1900

NO 4g Signal in XT1541 . Can i flash XT1550's Modem Files on Xt1541? Plz help!!

Hey there!
I have XT1541 ( UK edition Single sim 1gb ram model ) . I am on Stock MM noq and some days ago i bought a 4g JIo sim but it wasn't showing any service in my phone only. The same sim is working in other 4g phones so i flashed different roms including stock LP, MM and few custom roms but still it isnt showing any network. So, i was wondering that XT1541's modem files aren't working here in india for 4g Bands . So, can i flash the indian variant's modem files so i could get my network Back
Or if i am wrong, can you please guide me somehow because this issue has pissed me so much
@lost101 my 4g provider supports 2300Mhz or 1800Mhz or 850Mhz bands but i guess XT1541 only supports 2100, 1800, 2600, 900 , 800 Mhz bands . can you please help me somehow ??
No, you cannot open any additional LTE bands, and radios from any other device will not work properly. The LTE bands are locked in a way we cannot change them.
