How to use both /e/OS and Linux PostMarketOS Community pre-built image on Galaxy Tab 2
install instructions for Phosh and XFCE4 images
works running from a SD card
as explained in Installation - Flashing - From SD Card Our device can boot a SD card, USB stick or other external storage.
.
preparation in a way to easily switch between /e/OS and PostmarketOS
from your actual Android_OS install file (AP_Stock_Samsung_Firmware.tar.md5 or Custom_Android_Based_OS_like-e-is.zip), extract the boot.img and copy it to your TWRP folder in internal storage (/sdcard/TWRP)
Download the pmOS pre-built image
from the download page
insert a MicroSDcard into your Computer
and find its name by running
$ lsblk
make sure it is the right one as you will overwrite everything on it. Use a path without partition number at the end,
such as /dev/mmcblk0, or /dev/sdd
decompress the downloaded file and write it to your MicroSDcard :
$ xz --decompress --stdout /path-to-pmos-samsung-espresso10.img.xz | sudo dd of=/dev/name-of-your-SDcard bs=4M status=progress
Wait until the command completes and eject the SD card.
If you are on Windows, see here.
insert the MicroSDcard into your device, and boot it into TWRP
using the mount feature, unselect all /partitions except “MicroSDcard”,
using the install feature, switch to “install image” rather than “install ZIP”
navigate to the “/external_sd/boot.img”, and flash it to the /boot partition
reboot system
The rootfs image will boot right into postmarketOS. You are done with installing postmarketOS, congratulations!

to restore your /e/Android_OS
boot the device into TWRP mode,
and simply using the install feature, switch to “install image” rather than “install ZIP”
navigate to the previously stored “/sdcard/TWRP/boot.img”, and flash it to the /boot partition
to restore your PostmarketOS
boot the device into TWRP mode,
and simply using the install feature, switch to “install image” rather than “install ZIP”
navigate to the “/external_sd/boot.img”, and flash it to the /boot partition

Hi Folks, is there any chance to get a /e/OS 1.x or 2.x running on this device?
Hello @SupaKorni, welcome to this Forum.
unfortunatly not because last /e/ versions possible to build are :
- 0.21 for Nougat
- 0.21 for Oreo
- 0.23 for Pie
there are no sources available for :
- Quince Tart
- Red Velvet Cake
- Snow Cone
- Tiramisu
- Upside Down Cake
- Vanilla Ice Cream
Ah, thx.
So there is a possibility for a build with 0.21 Nougat instead of 0.9 in this version?!
Theoretically yes, but I could not build due to error with OMAP4 hardware sources.
doesn’t it the fix ?
Yeah, could do. Will try in the next days
I also needed to apply this fix and one minor other error

Will upload ROMs later
Wasn’t uploaded full and now is extremely slow… will try later

I just tested e-0.21-n-20240608-CUSTOM-espresso3g.zip,
I am sorry but after the Samsung_logo only a black screen is displayed, so i tempt a format /data → not better…
This device is reputed a nightmare to build, Only @Android-Andi have achieved it…
However @Mighty told me yesterday that there will be no problem to build /e/nougat from official LOS sources
hmm, I took the official LOS sources and applied the patches needed for hardware_ti_omap4 only.
maybe this is the issue or other patches needed too?
ok, last try. I applied now all patches I could find:
e-0.21-n-20240609-UNOFFICIAL-espressowifi.zip

i just tested e-0.21-n-20240609-UNOFFICIAL-espresso3g.zip
still a black screen after the Samsung Logo…
thank you for your time !
wich sources did you use ? those from @Android-Andi or those from @Mighty ?
The official LOS sources and patches for andi
Sorry, I am out of development for years now and by accident formatted the SSD with all sources synced.
Black screen could be everything… Selinux, wrong blob and kernel combination. Try to get a dmesg and see if you find something telling what’s going on and what not.
Best regards
Andi
