Is this a prerequisite to flashing? I want to flash Lineage OS on some phones and have been wondering about the necessity/importance of vbmeta.
I’ve putted Lineage OS with microg on a OP5 previously having /E/ OS not fashing vbmeta.img and it works.
Yes for recent Samsung (since the s10 series)
What about other phones (SONY for instance)? I’ve seen vbmeta.img on a lot of phones…
Sorry for hijacking the thread…
I use Linux for the installation.
Maybe it is more since android 10 ? (i only practice samsung)
Linux instructions from @corsicanu official maintainer of the device
https://xdaforums.com/t/recovery-official-3-6-1-x-twrp-for-galaxy-s10-e-5g-exynos.4180287/
Install heimdall & additional required packages:
Code:
sudo apt-get update
sudo apt-get install heimdall-flash android-tools-fastboot android-tools-adb libusb-0.1-4 libusb-1.0-0 libusb-1.0-0-dev
If you already have the bootloader unlocked you can skip to step 6.
- Make sure OEM Unlock is ON in developer settings;
- Turn off the phone;
- Use vol down + bixby key + 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);
5.** Please be aware all your data will be erased including internal storage and phone will reboot!!** - 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 down + bixby key + 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;
10.** If by any chance you see RMM state=Prenormal or KG state=Prenormal, redo from step 5!** - Download appropriate TWRP .img file according to your device
- Download avb disabled vbmeta .img
- Open your preferred terminal in linux and type (replace red lines with the path of downloaded img files):
Code:
sudo heimdall flash --RECOVERY /path/to/recovery.img --VBMETA /path/to/vbmeta.img
and press enter - once you press enter grab the phone and press vol up + bixby + power to force it boot straight in TWRP after flashing
!! Only if coming from full stock firmware
- In TWRP home screen press wipe - format data - yes
- Download and flash multidisabler-samsung-3.* zip to disable security and encryption.

It is working now. Thanks everybody for helping me.
I used a new cable (not sure that this was the cause of the problem) and redid all instructions.
I guess, I have made a mistake during the “Pre-Install Instructions” (https://doc.e.foundation/devices/beyond2lte/install)
At step 3 Power off the device, and boot it into download mode:
hold Volume Down + Bixby and connect USB cable to PC
Now, click the button that the onscren instructions coorelate to “Continue” and/or “Unlock Bootloader”.
was most likely where I made a mistake. This time I used a long press to unlock the bootloader. The device really needs to say that it will unlock the bootloader. It will look different and give warning not shown before.
In summary.
- The instructions given by the e.foundation are correct.
- There is a risk to brick the device if you do not follow the instruction
- Make sure you really have a compatible device (SM-975F/DS)
- There is no need for further images or tools. For Linux users: It does not harm if you install the heimdall & additional required packages as stated by piero (Problem with e installation on Samsung galaxy S10+ - #26 by piero)
- having a short (< 1.5 m) new data cable is a must-have
- If the screen does not look like the one at step Problem with e installation on Samsung galaxy S10+ - #14 by tyxo there is no point to proceed. With “Steps to install /e/OS from recovery”. Go back to the start and read everything carefully again before you perform a step.
