| WARNING: Make sure that you are prepared to (probably) lose functionality when installing postmarketOS. Samsung Knox will blow an efuse when the OS is modified that will permanently disable Knox-only features like Samsung Pay, and you will NEVER be able to use those features again (not actually tested for this device yet). | 
|  | While the kernel compiles and flashing is available, this device is in an extremely early state of development. | 
This is the Device page for the "Samsung Galaxy Tab S5e Wi-Fi" (model SM-T720; codename gts4lvwifi), which should not be confused with the similarly-named "Samsung Galaxy Tab S5e LTE" (models SM-T725, SM-T727; codename gts4lv).

How to enter flash mode
Recovery mode
- Power off the device
- Hold + untill you see the recovery menu.
Flashing mode
| Samsung devices do not use the fastboot flashing mechanism. There fore the flash mode is also not called "fastboot mode" but "Download mode". | 
- Power off the device
- Hold + .
- Connect USB cable from PC to the device and wait until the screen turns blue.
- Follow the instructions on screen (it will probably tell you to press to continue, i.e.: to flash mode)
Bootloader Unlocking
|  | Be aware, a bootloader unlock will erase all userdata! Make sure to keep a backup of any important data! | 
|  | The bootloader needs to be unlocked to be able to flash custom partitions. | 
Unlocking
- Boot to android
- Connect to wifi
- Enable "Developer Options" (tap 7x on Buildnumber)
- Go to "Developer Options" and toogle on "OEM unlock"
- Turn off tablet
- Hold + while plugging in USB untill you are in "Download mode".
- Follow onscreen instructions to unlock bootloader
- Reboot to android and connect to wifi
- ensure "OEM unlock" is still active in "Developer Options"
At this point, you should be ready to install custom ROMs/postmarketOS.
Installation
It is advisable to keep backup of some partitions for easy recovery before installing postmarketOS!
Backup with TWRP
Prerequesites
- TWRP. See here how to install TWRP
- adb on your PC
Create backups
Plug the tablet with USB to the PC and boot to recovery (TWRP).
Backup the partitions "dtbo", "boot", "recovery", "system" and "userdata".
adb pull /dev/block/by-name/dtbo dtbo.img adb pull /dev/block/by-name/boot boot.img adb pull /dev/block/by-name/recovery recovery.img adb pull /dev/block/by-name/system system.img adb pull /dev/block/by-name/userdata userdata.img
Manual build
The vendor is "Samsung", the codename is "gts4lvwifi".
Follow the pmbootstrap article, until you have done the install action (note that --fde stands for full-disk-encryption - this is currently not supported on this device).
|  | While the device is packed with downstream kernel in pmaports, the close to mainline kernel also boots on the device. Check the section #Build notes for further information. | 
Flashing
| When issuing the following commands with out the --no-rebootoption, the device will reboot after each flashing process. You might want to hold  +  to automatically boot to "Download mode" again. | 
First off, to boot custom images we need to disable Android Verified Boot (AVB). This can be done with pmbootstrap flashing a custom vbmeta.img.
pmbootstrap flasher flash_vbmeta
Then flash the rootfs and kernel.
pmbootstrap flasher flash_rootfs pmbootstrap flasher flash_kernel
| When flashing with pmbootstrap, a fork of Heimdall is used that is still maintained. This can also be used to manually flash the images, if needed. Other flashing methods might also work (Odin, from recovery, etc.) but are not tested. | 
Build notes
Mainlining
The close to mainline kernel for the sdm670 boots with a devicetree derived from the google-sargo DTS.
There are still a few things missing before Usia want's to update the device package to use the close to mainline kernel.
Things that already worked:
- cpu
- display (simple-framebuffer)
- bluetooth (it did work but was hacky to get connected)
- wifi (2,4 GHz worked in Australia with nl80211 drivers, not wext)
Things still missing (not complete):
- usb
- touchscreen
- charger
- battery
- audio
For the mainline kernel to boot you will need to flash a empty dtbo to the DTBO partition.
dd if=/dev/zero of=empty_dtbo.img count=1
avbtool add_hash_footer --partition_name dtbo --partition_size 8388608 --image empty_dtbo.img
heimdall flash --DTBO empty_dtbo.img
With the changes below the the mainline kernel is able to boot on the device.

Device notes
Some of the gts4lvwifi devices originally shipped with Android 9. LineageOS worked on those devices until sometime in 2020-Q4; after that LineageOS stopped upgrading. The solution for this was to install Samsung's stock firmware for Android 10, and re-flash LineageOS - after that it continued working. Mparker17 recalls this had something to do with Android 10 device drivers, and speculates it might have something to do with LineageOS's kernel fork or device configuration (which we use, see #Build notes above), and therefore, similar issues might happen with postmarketOS as well. However, Mparker17 doesn't know how to restore the original Android 9 firmware to verify this. So Mparker17's advice is, make sure you've upgraded to the latest official Android 10 firmware before trying to install PostmarketOS.
