Hi. I've used TWRP 3.X and LineageOS 16.X before in my SGA300FULTE before. But other roms or recoveries didn't work. Only 2 TWRP 3.X and the LineageOS 16.X by
@vl_w strangely seemed to work so I used them as daily driver. But these 2 became old and I needed new latest updated Roms and Recoveries. So I searched for new ones but found none. I'm glad when I found your this post a few days ago. Your TWRP 3.3.X is working somehow but the LineageOS 16.X isn't working. When I flash it from the Recovery and I reboot my device [ To remind you I always do full clean flash with wipe dalvik, cache, data, system and sometimes even internal storage ] it flashes and reboots and shows the Samsung stock Boot Logo/Splash Screen and the LineageOS also boots till the LineageOS boot animation. And it bootloops [ Either it keeps booting and showing boot animation forever or the screen gets dimmed with the boot animation completely freezed with the boot animation stopped ].
I was waiting for this latest TWRP 3.X and LineageOS 16.X. But It's very bad and sad thing that they're not working in my device .
:crying: I thought I'd use them like before as daily driver. But I'm disappointed now because of this. I wish it'd work. And I wish this device SGA300FULTE had more developers working with more things and also make it Project Treble supported. I'm also trying to experiment with this to make it Project Treble supported. I'm eagerly waiting for your reply. I hope you can assist me with this. Thanks.
Alright, let's go in parts:
1) It is very likely that this build is as old as those published by
@vl_w, it would not be much of being surprised the problems that this ROM brings.
2) No one, not even the one who published this ROM, has done any further research on GitHub (where development is done for the MSM8916) on what happened to development for Android 9.
3) There are already Pie builds made for some phones like Grand Prime (as expected [additional note] the weak or no development for fortuna3g or serranove) with changelogs in late 2018 or mid 2019, I don't remember exactly, Still, it was not wrong to consult at least here with some of the developers for such phones on topics related to driver compatibility mainly, as long as libraries and other components are tested in order to see if work something or not.
4) At least with a33g it is impossible to have a generic image because there is no way to create a partition from which it is required to make it work. An average developer for this model simply won't want to work on it since, equally whether or not there's a chance to have a dedicated partition, Creating such a ROM is said to be very difficult.
5) It is highly unlikely that we will have a sufficiently new Android Pie ROM available, much less for the A300FU (which in theory among all models is the one that receives the most support), the most probable but not totally certain reason (due to some mistake) is that the published changes on LineageOS are not available on the final ROM, i.e The battery icon setting.
6) There is no one capable or willing to try again the construction of a ROM (for each version of the A3, of course) with the latest updates from each repository for, In addition to discarding the theory of the old versions, to advance a little more in the mediocre development that there is, even being reporting every moment to GitHub.
7) It is believed (as I did) that a much easier way is to port a ROM ... with Brotli it is an impossible mission, with that I summarize everything.
