[Q] Samsung SM-G900 LTE Networks (Kernel problem?) - Galaxy S 5 Q&A, Help & Troubleshooting

Hello community,
I bought a original Samsung S5 G900F from T-Mobile USA.
Currently I unlock it and is open to all network. This cell phone is selled here in Portugal with all the carriers.
I have put the Cyanogen Mod (latest one) and now appears on the name of the cell G900T.
I need to configure it to get LTE Signal in Portugal (it currently only get LTE when I´m in the center of big cities). Don't reach LTE from all the antennas.
I think it is a problem related to the kernel cause I only root it and change the rom.
Thanks and please help me.

Help please

[Q] galaxy s4 gt-19500 compatibility with wind(Canada)

I bought Samsung Galaxy s4 Gt-19500 with Android version 4.2.2 out of Canada. The phone is sim unlocked. My original plan was to get a plan back in Canada and use it there. I found out that it was compatible with Rogers, Fido, and all the carriers who have a band 2600. Wind, Mobilicity, and the cheaper carriers is 1700/2100 and my phone does not work with there sim cards. I searched online and found this link:
http://forum.xda-developers.com/showthread.php?t=2291589 which is also with xda-developers but the download links on the bottom, downloaded 77zip which crashed the computer twice and also downloaded lots other programs with out permission. Is there any way to make it work with wind?
I don't need it to work with Rogers, Bell, Fido, or any other carrier after.
Much appreciated- Tyler
Hello i am sorry to tell you that the GT-i9500 does not have the chip needed to run on the wind net work (T-mobile in USA) the chip you would need is a qualcom chip the only international version that has that chi[ is the LTE variant of your phone GT-i9505 and no you cant swap chips nor can you flash a modem and get rid of that file that is crashing your PC if it does what it claims it does than its a lie and most likely a virus sorry for the bad news but my uncle had the same problem and thats why i have some experience with the phone i recommend you sell that one and buy the GT-i9505 or the T-Mobile SGH-M919 i personally have the T-Mobile version and no complaints just the bloatware but i flashed a rom and no more bloatware
Best Of Luck

[Q] Can I install a T-Mobile stock ROM on a AT&T unlocked version

Hey guys I need help... I got my wife an unlocked AT&T LG G2. I set up the APN setting and the LTE was working but as soon as I don't have a strong signal the phone drops to gsm and it doesn't give me the options to include other frequencies on settings. I worked with T-Mobile to fix the issue but they don't have a fix. I was adviced to flash a T-Mobile stock ROM is this possible if the build model is different?

How to unblock WCDMA B8 900MHz on a T mobile SM-G892U phone or do a cross flashing?

Hi everyone, I search a solution on my problem for days and I didn’t find the solution. I ask for your wises advices…
I’ve got a Samsung G892U on T-Mobile, but I’m living in France. The G892USQS5BSE4. I need the WCDMA B8 900MHz which is blocked by the T Mobile Firmware. I followed the advices of T Mobile forum https://support.t-mobile.com/message/684694#684694
But I wasn’t successful to change the CSC to another carrier. I tried to search for custom rom but apparently with my bootloader 5, I’m stuck.
https://forum.xda-developers.com/galaxy-s8/development/root-partcyborgrom-galaxy-s8-active-t3747788
Apparently, I can do a Cross-Flashing to ATT without root and with Odin. But I didn’t find any ATT firmware link…
Could you please help me to do a cross-flashing and get the bands free ?
Can you tell me if there is a bounty for a custom rom G892USQS5BSE4 or equivalent ?
Thanks by advance
Cross flashing
Ok I continue my investigation:
I found a rom ATT G892AUCU5CSF8. I can't post the link due to post restriction but I will later.
At least I manage to find a V5 Bootloader as mine.

I tried a basic install of the rom G892A on my G892U with Odin. Waht a surprise, I get a message secure check fail: pit
Do you have any tips to do this cross-flashing ?
Regards
