I have just received a nice refurbished S20+. This time it is a supported model, unlike previous (SM-G986U1! ). “oem unlock” was successful.
Now back in in download mode again via adb reboot download, I have to flash a recovery
Following the /e/Os doc , I am trying to load vbmeta.tar.
I only have a linux machine and so far I tried odin4 -b
$./odin4 -b vbmeta.tar
Check file : vbmeta.tar
/dev/bus/usb/001/045

Best if you use Odin for Windows (for linux it should work too, but I never tried) and follow this step:
Open Odin v3.14.1 and place the downloaded recovery.tar file in AP tab, downloaded vbmeta.tar file in CP tab and click Start - once you press start grab the phone and press vol up + power to force it boot straight in recovery after flashing
Use vol up + vol down + usb cable plugged to a pc to start the phone in download mode.
Long press vol up then confirm you want to unlock bootloader (this is needed one time only). Please note , ALL YOUR DATA WILL BE ERASED!
Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM.
Make sure OEM Unlock is ON in developer settings.
Turn off the phone.
Use vol up + vol down + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode.
Download appropriate recovery file linked above in the ‘Downloads for ‘ section. Compress the recovery.img into a .tar file with 7zip or a similar compression software, BEFORE COMRESSING THE FILE, rename the recovery to recovery.img
Open Odin v3.14.1 and place the downloaded recovery.tar file in AP tab, downloaded vbmeta.tar file in CP tab and click Start - once you press start grab the phone and press vol up + power to force it boot straight in recovery after flashing
Factory reset, Format data, cache and system
Go back, and tap “Apply update”
Tap on “ADB Sideload”
In terminal of your computer, and type “ADB SIdeload file.zip” (Replace file.zip with the respective file name)
Reboot to system
Success: Congratulations !! Your phone should now be booting into /e/OS !!
also you may need windows for that device
(something in my brain memory about first topics about this device on this forum…Heimdall 1.4.2 issues … but it was before Odin4 and Heimdall 2.2.2 comes to the game..)
If I read the /e/OS doc, it doesn’t tell to go in dowload mode via adb reboot download , but with buttons.
Indeed I don’t end up on the same screen. It is so weird! This time I have that wordier screen:
Thanks.
I am not very competent for the VM stuff . So I will ask for a Windows PC on Sunday if this cannot be fixed yet with odin4 (or another linux tool)
