First you cannot flash a Exynos cpu based rom to a N9005 (Qualcomm 800) device. For connection issues i would contact your provider for the right settings and look if you have the bands to support it.

4G not working s4 SPH-L720

Hey guys
First, I am not a U.S resident, my phone is unlocked so I can work with it here in Morocco with IAM carrier SIM .
My phone is an S4 4G SPH-L720 ( Sprint ).
Now I am using an official android 5.0.1 ROM . 3G is working fine, but when I select LTE/CDMA, and after reboot, the phone lose signal, no signal at all !
I tried to flash the last official ROM, but the same problem.
VERY IMPORTANT information ! In Morocco, 4G bands are " band 20 " and " band 3 "
and SPH-L720 supports LTE " Band 25 "only .
I found this thread http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
Is that thread going to help me get Band 20 or Band 3 to my phone ?

Hello,i'm new at that forum.Few weeks ago i bought s7 (sprint) from ebay and the firmware model is G930PVPU6BRD2 which has bootloader 6 and no other firmware is installing at that phone,otherwise it is bricked (i tried 4 or 5 firmware and root methods but no good result) and if i install correct (G930PVPU6BRD2) software it is working.I live in Georgia and there are 3 mobile operator which provides LTE bands and my phone refuses sim (it says "Invalid Sim").

Please help if anyone tried some working method for that problem!

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
