Samsung galaxy s8 fail and bootloop - Samsung Galaxy S8 Questions and Answers

Hello people, I need your help urgently.
A friend bought a used s8.
The old owner was still logged in with his account.
She tried in vain to achieve this, without success.
Since she is an "all alone" girl she has made a factory reset and behold, locked.
Now she started with Odin and Rome ..
End of lies, the device was stuck in an error message.
Now I got it.
Then I tried with twrp and Custom Rome, without success
The "OEM lock" is still set.
From the outside, I no longer have access.
Then I installed official Roms and at least managed to start it normally, initialized something and installed it up to another error message and slipped into a bootloop.
So, does anyone have an idea?
Because, I think that was it ..

Galaxy S5 Root not working

So, I was having trouble re-rooting my S5 after the XXU1ANG2 update for the SM-G900F international model as Odin kept throwing out a FAIL to write error every time I tried. After multiple attempts I finally figured out what was wrong with it. In my settings I'd selected the reactiviation lock, so that If I lost my device nobody would be able to get into it. So unticking this and do the usual root process and voila it works as per!
Just thought I'd share this information for anyone also having trouble

Galaxy On5 sm-s550t stuck at frp

So I've searched around the past few hours and can't seem to find a solution to my issue. I have a friend that is currently down on his luck and staying at a homeless shelter, he bought this phone because phones are pretty much a necessity nowadays, samsung galaxy on5, trouble is that the phone was locked when he turned it on so he was stuck with a paperweight, it's been a long time since I tinkered with phones but I figured I could help him out by booting into recovery and doing a factory reset. I had no idea about samsung factory reset protection and now were back to paperweight mode. I downloaded jodin3 and heimdall, but it never shows as connected. Can I root the phone while in recovery or load the factory rom so I can get the phone working again? Thanks for any help.
No, the only options are either ordering a remote unlocking service or find a guide on YouTube. The YouTube way will involve some patience and trial and error. Many guides don't specify what update on the phone they are working on and/or will state that their particular method works for EVERY phone. The stock recovery will tell you what update that it is on by the build number. This might help pinpoint which method to work.
FRP = Google Factory Reset Protection
Samsung Reactivation Lock is a different beast.
Which one does the phone have?

[HELP] Samsung S8 problems (Root, OEM, Firmwares, TRWP, Odin3)

Before I rooted my G-950FD samsung s8 phone, everything is normal. However, I accidentally restarted my phone with OEM off and stucked at the bootloop with blue screen says downloading. I tried various tutorials on how to use Odin3 and flashed the AP file to my device but apparently it doesn't work. The same message says "Only official released binaries are allowed to be flashed'". I'm stuck at the downloading blue screen page and unable to restore to the original samsung firmware.
Moreover, I went to the samsung help center to help me out but they said mine already void warranty so can't.. Only option they gave me is to buy new motherboard for the s8..
After that, i went to the third party phone repair shops.. they actually managed to bypass it and safely restored to the original firmwares. ffs samsung repair costs more than I actually send my phone to the 3rd party repair shops. I would like to do the restore on my own but what did I missed? I really want my phone to be rooted. But, the last time I rooted, and try to restart it. It will automatically soft brick my phone.
All solutions is much appreciated guys

Samsung S8-SM-G950F custom binary blocked by FRP lock

Samsung S8-SM-G950F custom binary blocked by FRP locked, i saw so many theards about this and i read them, and i still don't know what to do, so my question is if i download firmware with "SamFirm" and then use oddin will i get my phone unlocked from that ? As i had custom rom for year and half and today i got that error for the 1st time , also if the "SamFirm" is not good for that can someone give me link for firmware for my phone as updato and all other sites download soo slow at 15 kb/s and i can't use them it will take 20hours to download that (
Similar situation, I broke my S8 screen, so never got it fixed, and was recently without a laptop, so thought id use the S8 thru Dex, it all worked no probs, however, I used to unlock bootloaders to install custom firmware and os's but didnt think id done it on my S8 as it was still under warranty, so upon looking in the developer options, i saw that OEM Unlock was on, so i switched it off, not remembering rooting the phone, now i get same error it bootloops and says custom binary frp lock. Did u ever get yours sorted? I know my google account to login 2 it if i ever get the official rom back working, but trying odin and smartswitch restore im still stuck, just keeps failing, saying frp lock. Cant even get into recovefry mode to factory reset, didnt thiunk i had TWRP installed on it, but i must have. Anyway, if anyone can pls help me pls contact me here or at dcillusionz at proton dot me. Thanks.
PS - I tried downloading from SamFW and using Odin, but FAILED. Hoping u had some luck?
