Motherboard mismatch. - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hello, I had a Samsung Galaxy S4 Mini i9190 and was working fine until few days back when it suddenly died. Later I got a reply that the motherboard was dead and the new motherboard they installed shows i9197 at bootup.
Now I have a motherboard that supports 4g while the phone originally was 3g. The stock ROM is running fine. Now which ROM should I install, that of i9190 of i9197 ?

Definitely i9197

[Q] Bootloader for T-Mobile Note II

Hi everybody!
Allow me to post the whole story so you can understand what happenend and then, I hope, help me..
I have a Samasung SGH N7100 (that is what is written under the battery) 16GB that came with a stock T889 rom. I had some bugs, I thought it was because the first user of the phone messed it up flashing a bad firmware so I tried flashing a custom rom (N7100 Slimkat 4.4.4 build 9) it went ok but I had no more mobile network. Then I tried flashing N7100 stock rom+pit+bootloader with odin. (I never should have ) Then I figured out that odin recognized the phone as T889!!! I think the mainboard inside is a T889 one . So now I got a T889 stock rom and tried flashing it, but it gets stuck at the samsung logo. Tried wipe/ factory reset, nothing works. I think it comes from the N7100 bootloader I flashed with N7100 stock rom. SInce, even Slimkat doesn't boot anymore (stucks at samsung logo too). Please; may somebody help me :crying::crying::crying:
Thank you!

Running Fulmics 5.3 (since last Sunday, used since Version 1.0 without issues!)
Trying to get MMS working when a bluescreen popped up and I can't get the phone to boot, recovery or download mode.
A green screen came up once when trying to get download mode but I had to get my sim out, and now it won't come back.

That must be some hardware problem. Are you sure that if your phone is not refurbished because after flashing a custom rom in a refurbished phone such problems occur. You better take it to some repairing shop this is your only option in my opinion because the same problem happened with my cousin LG G3 mobile. It was refurbished and after flashing a rom it was nearly dead.

Nope, it was brand new when it was first released.
Just got a D852 basically new for $100 so will try to fix it and sell it (unless any developer reading this wants it?)
