so i have an Galaxy S20 Ultra 5G...but the Homemenu is weird....it only have the Phone and Camera app and everything else isnt present. If itry to open menu..nothing happens. If i try to enter recoverymode it says no command (i can only acces the android recovery not the Samsung one) and i did another button combo which let me to a menu called Factory Mode. The Bootup and Shutdown logo are weird. if i boot up it shows a white background with Red letters saying Hello....same for shutting it down only it says bye bye. i cant enter downloadmode aswell. so is it possible to flash a rom via Fastboot mode because that i can access. i uploaded some pictures.

Where did you get it from?
I don't think that is the S20 Ultra, bezels look too thick for starters, camera looks too big and too far down from the top of the screen too
See my S20 Ultra on the left for reference

Hmmm....at first, i think they sold you a copy of the S20 phone ... if you can go to the phone keypad, try typing * # 1234 # ... to see which model it is..

No because it's not an S20 Ultra so the S20 Ultra firmware will not work

They are fake phones, the S20 Ultra 5G ships with Android 10 for starters and like others have said the camera is too far down so if your uncle brought them in good faith then unfortunately he and you have been scammed.

You will brick it if you flash S20 firmware on it, it is not an S20
Is it even a Samsung? You need to figure out what model phone it is, then you can download the correct firmware for it
Try this app, post screens of what it says

i cant install anything...all it has is the phone and camera app i cant even access the apps menu...and this is what it shows on bootup

Android version 5.1, it is a very old phone whatever it is
I cannot find anything related to the info it shows though, and you're not going to be able to flash any modern firmware to it, unfortunately you've been sold fake phones
Try factory reset from that menu, maybe you can get access to the OS once it resets

Hey guy i i have a SGS with version DXJG4 and this device dont have donload mode 3 buttons do not work and also do not work ADB reboot downloader
the device just start up and thats it.
Only i can get root with the universal ADB tool so super user i have it.
I can put the device in recovery mode with ADB thats it and can use update.zip.
I also try to flash a back up update.zip XXDj3 but that flash only PDA and CSC not the PHONE part after reboot still phone DXJG4
So can anyone help to activate downloader mode i think is disable.
If not i will return the device and try to get new one.
Have same problem here, my sis SGS bought fr singtel, 3 button download mode cant activate, I have no problem on my Maxis SGS unit. Any guru pls help!
"ADB reboot download", not "ADB reboot downloader"....no "er" at the end
My SGS shipped with .....JG4, no hardware method as well. I used to turn the USB mode into debug mode for safty
weird. i'm able to flash mine as per normal. same set from singtel too. maybe try a factory reset / cache wipe first? that's the only different thing i did i believe.
try this solution
http://forum.xda-developers.com/showthread.php?t=754673&page=3
My set is from Singapore too, i had no problems going into download mode. My firmware before i flashed was DXJG4 also.
Mine also don't have 3-button combo.
But i can get into download mode via adb (adb reboot download).
So singapore users are also getting Bell type phones? Interesting.
Same Problem here
from Australia Optus
Turn off
Remove battery
Wait
Put it back
Press vol down + home + power
Fixed ^^
I spoke to samsung yesterday and they said that the new firmware would enable it after they release a,new version of kies with the drivers, installed.
I honestly doubt that. The recovery option seems to be independent of firmware... unless if there's a software lock blocking it.

I can only say what they said when I spoke to them, she also said that the test bed phone they had been using didnt have the 3 button combo and after the update it did work.
when is this supposed update due out??
From what I understand within 2 weeks or so
We should all know the relationship between singtel and optus.
Anyway samsung australia said there would be no fix.
I'm on DXJG4 and I can enter download mode.

I am having trouble accessing download mode on my Samsung Galaxy S4 Mini (GT-I9195). I have tried and re-tried the vol down + home key + power to no avail. I am starting to think I might have a fake, but its locked to O2 network in the UK. surely a fake would be unlocked? also I have tried a few apps genuine Samsung app and cpu-z both say the phone in a genuine Samsung Galaxy S4 Mini (GT-I9195). I run the imei number and all looks legit there also.
I can access the recovery node via vol up + home + power. but no download mode. the volume key works fine as well.

I am at a loss and would appreciate any idea's or suggestions please. Thank you.

From the screen shot, the phone looks legit. Plus you can access recovery mode, so I don't think it fake. I also had a friend that has a genuine S4 mini bought out of carrier contract and cannot access download mode...

If you are sure your tablet is charged & still you can`t get into download mode ( just try charging it for couple of minutes & try volume down + power ) , if you couldn`t get this ,then unfortunately you have a bricked device .
Flashing incompatible firmware ends up with bricked devices.
The device is bricked because of the incompatible firmware.

Last thing to try, if you can get your hands on a download mode dongle from the S2 days it might get you to download mode but this is a long shot. If you flashed the Note 10.1 2012 firmware you will probably have flashed the bootloader and as such be REALLY bricked.... The only way to fix might be to buy a "broken" note 10.1 with a bad screen or something and swap out the Main board... Just be aware you will inherit any problems associated with the new mainboard and will most certainly get a new IMEI/Serial number in the process....
Make sure it's not a mainboard that can't use your networks ie verizon with it's locked bootloader...

I Cannot Help You Fix Your Phone
Sorry
Samsung always does crap different. They integrated the nasty vertified boot but does not enable fastboot mode which allows disabling it. At least as far my knowledge reaches, your phone is just to me a fancy, glowing paperweight, although I know telling you that is heartbreaking.
Your options could really get up to:
Find, some other posts related, or senior members and developers who are helpful, or Google 'vertified boot Samsung bypass' as a last hope.
Define your A50 as obsolete, (maybe cry for your money then) sell it on ebay as 'parts / unfixable'. If you need the data protected, sell the body, screen, battery and dispose the motherboard in some known environmentally friendly way.
I don't recommend putting your hopes off, so I will provide some related posts from now on.
If you wanna get the data back, there is a (kind of hard) way to do it.
Unsolder your emmc chip and solder it onto a usb drive.
Also, replacing the EMMC storage chip may help as the corrupted data will be replaced, and maybe that is the answer of the problem but that requires high soldering skills which puts off most people.
i bought an A52s from ebay which is on retail demo mode. i managed to take the demo mode off however the phone doesnt have the playstore installed, cannot factory reset via settings menu or hard reset.
whenever i try to instal the playstore apk, it would install fine and then fail to launch.
