S5 Sport (G860P) Unable to Downgrade from 5.0 to 4.x to use the SSU.apk - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

Hi guys, i just bought the S5 Sport on Ebay and intend to unlock it to use with the GSM network in NZ. Unfortunately, this device comes with android 5.0 lollipop that can't use the App SSU to unlock
I have tried to download the older android version on Sammobile but i got the error message Fused 2 > Bin 1 when i tried to downgrade from 5.0 to 4.x. Just google the this issue and find out the reason that the bootloader is locked at 5.0 version, Samsung just only allow me to go to higher firmware, not the old ones
I also have tried to root and install Custom recovery (successful) and install the custom 4.x rom. Tried exactly what the other post said ( download the one for G900p and reflash the Kernel of G860P) but the phone keep restarting (i've tried many roms on XDA, on one works)
So anyone help me to how to downgrade the android of this S5 Sport Or another method to unlock Sprint S5 sport on 5.0 please.
thank you

anyone please help me

im also trying to downgrade to make sim unlock but still nothing. i cant even find a CM11 working link.

SM-G920R6 Firmware Help

I want to change the firmware of my Galaxy S6 (SM-G920R6) which is Verizon LRA device. I want to Install a stock rom like the rom of SM-G920V or SM-920F or SM-G920T..
How can I do that? which firmware will be the best for it?
I want to change rom because APN refuses to work - I edited a lot of files, tried every suggestion from here & other forums - nothing helped .
So I decided to change the rom in order to enable APN edit.
So, how do I change the stock rom of my cellphone to another stock rom? The SIM is working propley after I change some settings in serivcemode (So it's not CDMA anymore, it's GSM).
Please Help ! :crying:
Edit : BTW I used this in order to root the cellphone - so maybe G920T firmware will work? CF-Auto-Root-zerofltetmo-zerofltetmo-smg920t
My android is 5.0.2, please help.
Anyone?
This is a little off topic for the op but I really need help right now.. I rooted with CF autoroot for G920F no problem then installed TWRP 3.0.2-1 zeroflteusc also built for G920F model and in the process of trying to find a better rom as soon as I had a custom recovery, me (being a dumba**) accidentally wiped my internal storage to do a clean flash of a rom therefore deleting the only backup I had. I've only been able to find the factory binary for this device which I flashed but it had literally nothing exept for basic testing software and a simple ui to run it. It was also stuck on Android 5.0.2 but I found a compatible rom with AllianceROM v1 with update v2 flashed for the G920F but I can't find any way to update past 5.0.2!! I've been trying to find a way to update somehow for weeks but nothing is compatible with my device and I'm stuck. Would someone that has my model running on Android 5.1.1 or 6.0/.1 please install the TWRP I mentioned before and make a backup of the system, modem, efs, and boot and post it online or send it to me it would be a lot of help.

Hello guys, can somebody help me?
I own a Honor 6x (BLN-TL10)
When I bought at 2017, I flashed my firmware to a different one cause I didn't wanted to use the chinese version, so I upgraded or downgraded to that firmware (BLN-C900B131) since that change, my device always recognize as hi6250, and when I try to install the original firmware on my device, It fails, on the update proccess appear that message, "Software install failed! Incompatibility with current version." cause I want to upgrade to 8.0 oreo, my phone right now is at android 6.0 emui 4.1.
Can you send the link of update file that you have used? And a screenshot of build number?
I'll attach 3 screenshoots, one of my EMUI and Android at the moment and the firmware's that I tried to install
The BLN-TL10 firmware that was the same that came with my phone when I bought
I've tried to unlock the bootloader, but Huawei phones bought on china doesn't have OEM unlock option enabled ;(
Idk if have some way to unlock bootloader without that option
