[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] AoNKatastrofe:
No more problem, but:

HI, I made a mistake and am now seeking assistance.

My S7E is a G935A and I tried to install this LineageOS to fix massive performance issues (would literally wait 5-10 seconds before anything responded) with my device (which I attribute to overheating that I am unable to pinpoint the cause of, may be hardware related tbh). I tried to use heimdall following the documentation from the LineageOS website but I couldn't get that to work. Then I tried Odin to get TWRP but flashing the image always failed, I made sure it was the right one for hero2lte, latest version too. After that, I remembered that I was already rooted and I had FlashFire in my device from the root process, so I tried to use FlashFire after reading a bit up on it to flash the LineageOS, MindTheGApps, and the SU zips from there. I selected wipe (defaults and some extra cache partition I can't remember), LineageOS zip (selected the second option for mount, the one that isn't auto), and defaults for MindTheGApps and the SU zip. I tried to rearrange the action list by making wipe the first thing that happens, then flashing LineageOS zip, then MindTheGApps zip, and then SU zip (with the reboot option at the very end of the list) as that was the order that I made sense things needed to happen. What happened afterwards was that my phone displayed FlashFire after a small period of time (of the screen going dark, as per the warning) in the top left corner, and then it rebooted into what I believe to normal android 8.0 as if it was factory reset (I don't see any LineageOS text or the animation). Looks like if it just wiped the phone to factory default.

I ended up finding later (or so I believe from what I've read) that I have the snapdragon model and that you can't (? really not sure on this part) flash TWRP for that particular version, but I had already flashed the zips because I only read hero2lte, thinking it meant all of them, oops.

The problem is that I can't get past the "Accept Terms and Conditions" screen because I keep getting a "Pixel Setup has stopped. Close App" and "Setup keeps stopping. Close App" and it never gets anywhere. This happens all throughout the "Start" screen (where you select a language), the "Connect to Wi-Fi screen", and lastly, the "Agree to the Terms and Conditions screen".

I am able to get into stock recovery mode and download mode. I tried to flash what I believe to be stock S7E with Nougat (was stuck on the Samsung S7E logo), then I flashed Oreo (which I flashed before when I rooted the device) and I was able to get past that stuck logo screen but now I still can't get past from the "Pixel Setup keeps stopping" message on the initial setup to configure the phone.

I've discovered that in the last screen that I can access before the app crash stops me completely if I spam "agree" (to get past terms and conditions) I can see that the device goes into the next screen where it displays "checking for connection, this may take a moment" for about a second before dying mid-animation and switching back to the agree to terms and conditions screen.

I don't know where the error originates from, but I've read that it happens in LineageOS from flashing outdated GApps, though it doesn't look like I have LineageOS.

Disclaimer: I just want to say I'm not blaming anyone but myself, lol. I'm looking for help to restore my device to any working condition without regard to OS. I've tried to wipe to factory defaults from stock recovery but it does nothing to help my situation.

Turns out the image for Oreo I was using was the modified one for root, not STOCK Oreo. Flashed the real stock Oreo through Odin and my phone is back to working condition. Phone still overheats so it's definitelty hardware problem, technician time. Figured I'll leave this here in case someone is dumb like me :silly:

I do have a question, however, is it not possible to install this on SM-G935A, I'd prefer to have it than stock Oreo.
