[UNOFFICAL BUILD] Samsung Tab A 2015 9.7 SM-T550 (gt510wifi) for /e/OS R

Did you try the current version too?

Bit of a problem, having two threadsā€¦ I did not look at that one at all, as it has no mentioning of the SM-T550 in the title.

Those I have tested in various ways:
e-1.15-r-20230912-UNOFFICIAL-gt510wifi.zip
e-1.18-r-20231223-UNOFFICIAL-gt510wifi.zip

Currently running on all three SM-T550, with no install/boot issues ever:
lineage-18.1-20231212-UNOFFICIAL-gt510wifi.zip

SM-T550 is correct for WIFI version and SM-T555 for LTE version

We have added some clarity on the thread in terms of device wording- should be clear now

Can you please try this version. I found now the correct sources and applied the needed patches:

Sorry mate, neither dirty or clean booted.

Will try with the LOS boot.img tomorrow.

I think I put the recovery in the ZIP file if you want to try this

The recovery as such works, but no /e would boot, also not with LOS BOOT.IMG flashed.

It does flash this one fine, too:

lineage-18.1-20231212-UNOFFICIAL-gt510wifi.zip

which I have come to like, as I got 3 very usable tablets now.
Battery life still stuns me!!!

Iā€™m still happy to test /e builds, of course

Please try the Q build:

No luck. It does not even load the /e Boot Logo.

Flashed other boot.img, used TWRPā€¦ no boot.

Can you try Pie version please:

Going straight to ODIN, unfortunately.
Donā€™t you think, with the tremendous amount of ROMs you have build by now, you could simply reach out to the LOS developers and get help on how to make your builds to boot /e ?

Did you do always a clean install. Please have a look at the XDA forum pages which TWRP is best to be used for the gt510wifi Android versions.
I usually ask if I cannot build the respective developer(s) in XDA forum. If I can build and it does not boot it might be /e/OS related. I would need someone to debug boot processā€¦

Yes, I do clean installs, wipe & format everything.

This is sort of what I mean, get a dev to help, what /e needs to boot ā€“ after all they have figured how to boot LOS on those devices.

Q5. What TWRP should I use?
A5. You MUST use TWRP 3.5.2_9-0. Get it at.

One last try for Q, I did use different sources:

e-1.17-q-20240121-UNOFFICIAL-gt510wifi.zip
https://sourceforge.net/projects/eosbuildsronnz98/files/SamsungSmartphones/e-1.17-q-20240121-UNOFFICIAL-gt510wifi.zip/download

I tried to build with S sources but got this error.
frameworks/av/services/camera/libcameraservice/common/CameraProviderManager.h:37:10: fatal error: ā€˜/mnt/media/e/eOS_S/hardware/interfaces/camera/provider/2.7/ICameraProvider.hā€™ file not found

Oh well, It gets to about 4 jumping eā€¢ , freezes for a second and goes into a boot loop.

ok, bad luck with this device and /e/OSā€¦

OK, I left out the camera and audio patches and could buildā€¦who wants to test?
