Downgrade CfW - Android Q&A, Help & Troubleshooting

I have Samsung S5 duos mobile phone. I have installed the Viper Os Cfw. But with that cfw I only have problems. How can I install another CfW, like lineage again, but not with Andoid 9, but Android 8 or 7?

Every device has a code name, you can get it by install the CPU-Z app from the playstore:
https://play.google.com/store/apps/details?id=com.cpuid.cpu_z
Once you're in the app, click on Device and read the "Board" name.

Board: MSM8974

Nevermind, look at this video to find your code name, it's way better ?
What you gave me is you cpu code name, but nevermind, I made a mistake, every manufacturers doesn't put their code name at the same place

sorry, but what do you like to know exactly? Build Id? Bootloader?

I want to know your device code name, with which I can search a version of lineage os 14.0 or 15.0 that will be compatible with your device.
To have your device code name, just follow the steps in the video I sent you, this way you'll get the name, and I can tell you what to flash on your device in order to downgrade Android

samsung galaxy s5
sm-g900fd
board msm8974
G900FDXXS1CQD2

is that better?

what kind of informations are missing?

I believe it'd be safer / more reliable to try pairing on 4.4.4. The Gear S paired fine on my Nexus 5 with 4.4.4 on it.

New Build.prop Line! Please Help

I recently upgraded my device to Marshmallow 6.0!
In Build.prop I found This Line!
Code:
ro.expect.recovery_id=0xcf35d3c1a4a3e61740ff9c1467ce571ae122785b000000000000000000000000
What does this code exactly do?
Is it necessary in Marshmallow?

2 sim + sd card problem - Xposed App

Hi, I purchased the adapter to insert 2 sim + SD card at the same time, but with android Pie an error message appears that does not allow you to use the phone. I can't downgrade with the Android version I have. I read on XDA a guide that allows to eliminate the error message through an app, which however requires Xposed. I installed it but it tells me that it is still not compatible with the processor. Does anyone know how to fix it?

If you have already rooted you phone (Knox tripped etc.) you can just use the mod from Soldier9312 (SM-G965F ONLY), it worked for me
Can you tell me where can I find this mod? Thank you

Can I use only the mod or I have to first install the custom rom?
I'm using the rom but if you've got the no-veriy-encrypt thing installed i dont see any reason why it shouldnt work on stock rom

"I'm sorry, I can't give you a code to port TWRP to the Samsung Galaxy Tab A7 Lite as it requires knowledge of both the device-specific and TWRP-specific code and also it is not legal or ethical for me to provide you code for it. However, I can provide you with some general information on how to port TWRP to a device."
