SM-G935F Stuck at download mode after a sudden freeze - Samsung Galaxy S7 Edge Questions and Answers

Hi everybody,
My Samsung galaxy S7 edge (G935F, Android Oreo) is now stuck at "Downloading do not turn off target" screen. The problem started after i uninstalled some apps and PUBG due to low space notification. After that the system frozed and stopped to respond, so i forced it to restart ( Volume down + Power button) and since then the phone reboots without showing the usual carrier and the samsung logos animations. It shows a "scrambled/damaged" image of the download mode which become normal after some seconds and stuck at this stage.
The detailed events time-line of the booting process is bellow:
1- the phone takes about 30 minutes to boot to the download mode
2- The carrier + Samsung animations logos were gone and not showing as before
3- some seconds before the download mode screen shows, a sort of a damaged download mode shows up and become normal after that
4- The download mode screen contains not text (usual firmware informations etc.. were not showing anymore)
5- The phone is stuck at this stage and there is no possibility to boot to safe mode or recovery mode or any other mode
*The phone is unrooted
*I tried to reflash the firmware with Odin (3.14) but it stucks on getting PIT stuff and fails with "There no PIT partition."
*i tried SmartSwitch and Kies but they failed too (i have no recovery code).
*Samsung usb drivers are installed
The screenshots of the phone and odin are attached bellow.

GT I9505GSMH chinese version in inedit boot loop?

greetings. my gt i9505 chinese version is almost dead. I am experienced in custom roms installation methods but this time I have no repertoire. It goes into download mode, odin recognizes but kies does not. I've installed all the drivers twice but it doesn't appear as ADB in the device manager. By Odin I was able to reinstall the original sam mobile rom, it even appears on the download mode screen under "current version = Samsung official". But it doesn't complete Boot at all. Only once did he enter the initial animation, but everything went black and the blue led was left and nothing for more than 30 minutes. Anyway, do not enter recovery mode or start any rom, just enter download mode. If I open Kies it crashes in download mode, it only works in odin. Yesterday he went to start and was vibrating non-stop. Help me please!!!!

Galaxy S8+ in bootloop without recovery and frp locked

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.

Samsung S10+ (no solution problem): Bootloop download + no PC visibility

Hello, I have 2x S10 + Performance Edition (White and black)
SM-G975F/DS
1.5 years ago, the bootloaders were unlocked and the magisk (android 10) was installed, some time ago the root was removed by a normal restart in the black one
I updated the second (white) with odin to android 12, but then I couldn't root it at all, it just crashed a bug every time (while making magisk zip or after all while trying to start the phone), finally had to install stock 12 again.
I decided to sell black one, but now I have a problem that I cannot solve. At first I tried to lock the bootloader, it hung on the samsung log for 2-3 hours, then reseted it and crashed into a bootloop. Download screen and at the top the message
"ODIN MODE (AVB Fail) avbmeta: Error verifying vbmeta image: OKNOTSIGNED (3)
CUSTOM CBMETA
CBMETA: No sign info
VBMETA. "
From this position, I can reset it (vol down + power), quickly hold down vol down + bixby and connect the power to get to standard downloadmode.
Once I managed to start the system somehow, but I have no idea how. Cannot go to recovery, cannot start the system, it only bootloops to "downloadmode" with description above.
Normally, I would just install new stock with Odin, but the real problem is that my PC doesn't see the phone at all, nothing in Devices' manager, nothing in Odin.
When It comes to the white one - everything is visible and fine, so there is no problem with cables, drivers or PC itself. This phone is messed up.
I have no idea what to do with it now, any suggestions?
Thanks a lot

Problem with LG K8 model: LG-K350N (download mode not working)

Hello, I have a problem with my old phone. The phone does not turn on to the system or download mode. After connecting to the charger, it charges normally and then restarts either to the words "Your device is corrupt. It can't be trusted and may not work properly." or to a security error. When I try to turn it into download mode, the LG logo is displayed with in left down corner text downlaod mode, then the message Your device is corrupt…. and it restarts.
When I enter the phone recovery, after clicking the buttons, the same message appears (Your device is corrupt and so on).
Thank you in advance for your help because this is the first time I meet it + there is nothing about my problem with the download mode.
