[Samsung Galaxy S8 Questions and Answers] Sebastian6600:
Hi guys!

I've read tons of threads and guides on Google but nothing helped me to bring to life my Samsung Galaxy S8 Plus. After hours and hours of test and probes I surrender!

Basically I was using normally my phone and suddenly has power off and showing the Samsung Galaxy Logo continuously. I've force reboot it with vol down+pwr button and after some minutes restart normally again. After 5min again the boot loop and stuck there. Tried again to power it off but didn't work so I thought was the battery (because is 3yrs old with heavy use and months ago I had the screen flickering and a battery drain to zero). I opened the phone, unplug the battery and the power button (because I thought was the power button stucked as on my father phone). So after mounted all the stuff in their place I tried to boot it and suddenly start to work again! I've backup all my things rapidly but again power off by himself and this is the last time I see it working.

So I tried to empty the cache entering in the recovery but it was useless so the only way seems flashing the original FW with Odin. Downloaded the right one with Frija, upload the rights files in Odin (Home_csc because I don't want to lose my internal memory stuff) and the phone automatically reboots, pass the Samsung logo and go in Upgrading mode with the blue android screen and a % increasing. After that by himself power off and nothing happen.

I read some stuff about my possibilities to recover it without losing data but a lot of tutorial talk about entering in recovery but I cannot do it! Simply does not go in recovery with vol_up+bixby+pwr_button even after force shutdown it with vol_down+pwr_button or reattach the battery. The only thing I'm allowed to do is put it in Download Mode to be recognized by Odin.

I've tried to launch ADB devices but it is not visible in Download Mode.

I've tried to flash another firmware for the same model (theoretically my one is unbranded italian) but I tried with WIND one because in download mode there is a text "Carried_ID:WIND" but this FW Odin fail to upload it.

I've tried to flash the TWRP with Odin but fails on the phone with error "Custom binary(recovery) blocked by FRP Lock". I've searched how to unlock it but without have access to recovery or phone settings seems impossible. And this phone has also OEM Lock.

I've tried again to flash the FW but the only difference than before was the blue android robot with stucked text "Installing system update", "Erasing" , "yellow advice notice" and finally a green screen with "An error has occurred while updating the device software.Use the Emergency recovery function in the Smart Switch PC Software". And yes, I already tried with Smart Switch but the program does not detect the phone.

I've also tried to flash the original recovery but nothing change.

Seems that my devices is bricked or a kind of boot loop.

In my situation there is something that I can do to recover the internal memory data? I don't tried to flash the FW with CSC file because I don't want to erase all the data.

My Galaxy was original since the purchasing, no root or flashed a FW, only OTA updates.

I've attached a photo with the stuff that appear in Download mode.
