[ROM][9.0][UNOFFICIAL] Nexus Stock for 2019 Galaxy Tab A 10.1 [SM-T510]

[massivekind]

Fantastic! I flashed BL, AP and CSC without USERDATA and it worked perfectly. In awe of your knowledge!
Thank you both very much for your time. I'll be sure not to jump into these things half-cocked in the future.

Good to hear :highfive:, no problem, I also started with not allot of knowledge. ( like everybody)

HEllo,

i'm still getting the "Tablet's bootloader" warning message at boot. Can this be removed?
I'm using this tablet in car and it makes the boot time to increase. Can this message be removed and also some way to speed up the boot time?

Thanks

No, that's done entirely in the bootloader, and messing with the bootloader is very risky business (not to mention difficult, since we don't have source). One wrong move and the device is permanently bricked. All I've been able to do is reduce the warnings so that they don't sound so scary, which is just replacing bitmaps in param.bin.

And is there also an easy way to change the boot logo?
Since i'm using the tablet as my car screen would prefer to have the logo rotate, is it possible?

The param.bin is just a .tar archive of .jpg files. Swap out the images you want to change.

But is it possible to do it without flashing the full rom again?

Yes. You can just create a .tar of the modified param.bin and flash it with Odin. You don't even have to compress it with LZ4 or include the MD5 checksum.

Ok, i uncompressed the param.bin and edited the logo.jpg.
Then i compressed all files again with 7-zip as a .TAR File.
Opened Odin 3.14.1, started the tablet in download mode, on AP choose the param.tar file, hit START but odin just crashed/closed.
Am i doing anything wrong?

Ok, i figured it out.
I need to compress the param.bin as tar.
It's working now.. Thanks a lot.

@Magendanz is there a way to enable the Adaptative brightness mode in this ROM?

@Magendanz is there a way to enable the Adaptative brightness mode in this ROM?

Apparently, it can with the right vendor overlay. I will add one for the next release, but for now you can try this.

Hi, I have only access to the bootloader Inna t510 for a member of our congregation. It looks like it failed an ota.

Is there a stock ROM i can install?

I have a kernel length error.

I assume I need a specific build to match.

Or take a chance and go for the oldest ?

I tried the newest stock.

Would not recommend this rom, at all. I used it for about four months because I was waiting for android 10 to mature and it was nothing but one headache after another. Among the many issues, the three significant ones were:

1. Changing tabs (the little square icon at the bottom) always resulted in the app resetting. For example, I'm browsing a reddit app on a specific subreddit, I'll be several pages down and either minimize it or press the square to change over, and check my gmail. When coming back to it, the reddit app would either be reset to the front page or reset to the top of the subreddit I was on.
2. About twice a week, some app would crash for reasons unknown but then it would work again. The problem was that after I either shut down or tried to restart the tablet, it was softbricked. I could hold the power button for a minute, nothing would happen. Plugging it into a charger didn't work, no response at all. It eventually turned on again after holding down volume + power but it would take forever.
3. Games would just stop responding to my touchscreen. No idea why.

This rom was poorly written, it needs to be retired. I was only using it because there was nothing else available at the time.

This is a feature of Android. If memory is low, the OS will quit background apps and resume them when brought back to the foreground.

This sounds like the cold charge bug, which was fixed in March.

3. Games would just stop responding to my touchscreen. No idea why.

This is the first I've heard of any touchscreen freezing issue. I also have no idea why it would happen.

There is nothing "written" in this custom ROM. It's just the latest LineageOS 16.0 GSI (which I build for @AndyYan) with OpenGApps, a tweaked Pixel Launcher layout, custom boot animation & wallpaper, and fixes for cold charge & MTP. I do, however, offer a double-your-money-back 100% satisfaction guarantee.

You are aware this tablet has a very nice processor and costs a lot, right? The memory was never low, always had several hundred megabytes to spare. I could be running a 1080p movie through vlc on a network share, while downloading an nzb at 50mbps and still have room. I've switched to other roms since then and it hasn't been an issue since. Cold charge bug? No. I would be playing with something, then the tablet pukes and recovers but after I shut down or try to restart, nothing happens and it becomes a brick for a while. At no point in time did I plug anything into a charger. The other one I forgot to mention: A few times a week, usually when it crashes, the wallpaper would reset itself to stock.

Now you've lost all credibility. Only 2G of DRAM is pathetically low for an Android device released in 2019, and the Exynos 7904 processor performance is mediocre at best. This is why Samsung has only released it on ARM32 architecture. But what do you expect for a 10.1" tablet selling for < $200 USD at Target right now?

Seriously, though, if anyone else is experiencing these issues, please chime in here. I'll happily pull the plug on this custom ROM, as @riverstyxxx suggests, but I suspect that this is not a widespread problem or I would have heard from other sources.

I use the AQ and it is fine. Not just fine, terrific.

I have no such issues and my Tab is running very smoothly, so please don't pull the plug on this ROM. :good:

 

[Osaka_23]

Please don't pull this ROM!
This ROM is amazing! It has significantly the performance of my tablet. It is much speedier than Samsung's stockrom.

Thanks for putting so much time and effort into this wonderful ROM. I really appreciate your work.

Lastly, there's no pleasing some people. They don't understand you have created and maintained this ROM for free and in your time.

Yes I agree there are some minor bugs, but still a million miles better than the laggy stock ROM.

Be grateful and appreciative someone has spent then own time creating the ROM.

 

[BortFrenzy]

This is my vote of confidence in the ROM. Works great for me!

How to get Netflix and prime video to work?

After a long contemplation, I finally installed the ROM. With no doubts, it performs faster than the stock rom and feels much more polished than the samsung jittery mess.

I can't seem to get Netflix to work tho. I side loaded the latest version, it would launch fine but finally stuck on a unless loading screen when trying to play anything. anyone have solutions for it?

(For prime video, it would play fine in SD after installing Magisk without further tempering; if anyone know how to get it to stream in HD, it would be much appreciated)
