Anybody tested it ? Those Galaxy tab 4 were really famous tablets

I have and my kid. Works like a charm.

Note - I tested from a fresh install.

Thanks ! I’m wondering for a client you wants to change the battery to keep this tablet forever , apart from maybe some high consumption in sleep mode , do you see any blocking point ?

matisselte and matisse3g build should also be possible since only updated device file are needed for that

Samsung Galaxy Tab 4
Update for /e/OS-T 2.7

I could test on a [matisselte], do you feel like building 2.9-t?

retiredtab does not have a [matisselte] version. So how do you build it?
Also would you build a plain LOS version, too?

Did you try 2.7 T build?

:x:
Sorry, not booting at all, stuck at Samsung Logo.

ok, then a 2.9T build wout work. You might might try the wifi ROM on the LTE version

So, I patched the two files in the ROM with

“ro.product.device”) == “matisselte”…

and it installed fine

but then it went straight to ODIN mode, when rebooting from TWRP

:x:
So, no WIFI on LTE is not and option.

And btw, a baseline on battery life on LOS [lineage-18.1-20240901-UNOFFICIAL-matisselte]

can you try 2.7 or earlier please

@ronnz98
Maybe get in touch with Matteo to combine efforts:
Releases · matteo0026/OTA · GitHub

This is LOS18… final release for eOS is 2.3-R

Yes, sure.
But he got LTE working once, so maybe you two could work on a T version for LOS & /e !

Same as the others above.
