I doubt that it'll work, I tried it a while ago (I didn't test it myself) with added firmware files, updated kernel and device tree stuff and I used a very custom upstreamed samsung sm8250 common kernel which I had good experience with but it had the same issue, your commits are mostly updates for the twrp a11 source and new kernel source, so the differrences from my build and yours are that I have a more custom and upstreamed kernel with firmware but you used the a11 twrp source (which manifest wasn't available for me when I made it).
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bs3pro:
Appreciate the effort, we do need devs here. But whats the actual point of twrp, when we have ZERO roms to flash.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
Not sure what issue you're talking about here. The guy whose process I copied didn't seem to have problems, or at least not many significant ones.

If you did this same thing with a "very custom" kernel and were not successful, my instinct would be that the kernel was "too custom." The whole idea behind my method of customizing my kernel was to minimize the differences between what I built, and the kernel that Samsung shipped, which is known to be functional.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
I did this partially as a learning exercise, to familiarize myself with the Android build process. I'm still obviously fairly new to the Android scene, but the biggest piece of TWRP that I hoped to utilize was the backup/restore functionality.

Eventually I'm planning to try and install openSuSE on my tablet natively, and I wanted to be sure that I have solid backups, for when I eventually screw up and trash my device. I've learned through talking with jhill a bit that I'll probably get by just fine with just the stock firmware available to re-flash, but I wasn't entirely positive about that when I started working on this, and I figured I'd already burned the time building the kernel, so I might as well finish the job :P
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bs3pro:
Keep up the good work! Not complaining, just wish we had a couple devs making aosp. Thanks
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Bushcat:
There have been many people testing ianmacds build and trying to build twrp for the tab s7 but everybody had this blue screen issue which made the twrp screen unusable but you can use twrp from usb.

Ianmacd and other users tried it with a slightly modified kernel from samsungs source, I wanted to try a differrent kernel because samsungs kernel source can be ****ty sometimes so I tried an upstreamed lineageos samsung sm8250 common kernel (which I'm also using for my galaxy tab s7+ TWRP and PBRP builds and it's working well there) but it had the same issue. The Tab S7+ also has a small display issue in twrp but it's still usable, when hitting some ubttons in twrp you can sometimes see a small flickering stripe at the top. In twrp it's hard to notice but in PBRP this issue was very annoying because it happenned much mnore often and longer, it got very bad when you turn off and on the display in recovery, I was able to lower the glitches with some screen values like timeout but I wasn't able to fix this issue.

Welcome to the tab s7/+ dev community, I'm searching for more devs and custom stuff for our devices but sadly we aren't many, I've started trying to make Lineageos for the tab s7+ a while ago (my first from the ground up tree but I maintain ResurrectionRemix official for the OnePlus 6T since january) and I got further in small steps but since I'm stuck at this kernel issue since a month (I don't have much time atm but I'll try harder soon), the kernel doesn't want to load the fstab, I tried los17 and 18, asked many devs about this issue (jimbok77 mentioned a los18 init issue for the galaxy 20 series), this is my first device with dynamic partitions and my last samsung device was a samsung galaxy s5 mini exynos G800F, you can find more about my progress here Interest thread s7+ Lineage os and in the tab s7/+ development telegram chat, and you can find testers at telegram chat by ianmacd.

My plans are to make a working lineageos and then postmarket os, ubuntu touch and jing os.

[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
Thanks for the explanation. From what I understood, nobody had really attempted a build for the T870 yet. I was unaware that it has been tried, but nobody has gotten it working. Judging from the fact that the TWRP source has been shown to be functional on the S7+, I'd assume that this is still a kernel issue, but knowing that certainly doesn't help anybody find what the actual issue is, haha.

The "custom ROMs" side of things is something I don't really have any knowledge about. To be honest, I don't have a ton of interest in going down that road, at least at the moment, as I don't really understand what benefits I would get from a custom ROM. From my point of view, I'm much more interested in getting "plain old Linux" running on the device, as that makes it far more powerful and useful, IMO.

A big part of what I want to do with my device is to run gaming console emulators, and the whole added layer of complexity of needing to write a Java wrapper around an already-functional C program just to get it to run doesn't really appeal to me. Again, this could all be ignorance of the real possibilities on my part, but I'm just trying to give you an idea of where I'm coming from.

Thanks again for the explanation of the current state of TWRP, and the introduction to some of the rest of what's going on out there!
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
Arrrgh, you were right. I finally spent the time to fully root my tablet and get my TWRP build installed, but the end result was exactly like the screen pic you posted. You can see the top of the screen, but everything else is just blue. Being new to TWRP, I didn't know how to pull the log at the time to see if there were any obvious errors in it, and I've already flashed back to stock recovery at this point.

I'll give this another go sometime later this week, or over the weekend, and see if I can learn anything else.

If anyone has some basic TWRP debugging tips that would be helpful. From what I've seen the number one option is:

abd pull /tmp/recovery.log

But I'm not sure if that is still valid, or if there are other things that can be done.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
Scratch some of what I said above. I determined that:

/cache/recovery/last_kernel.log

Contains the log buffer from TWRP booting my custom kernel, and:

/cache/recovery/last_kmsg*

Contain log buffers from regular kernel boots. I'm combing through these looking for any interesting differences now, but there's obviously a lot to comb through, and it takes some effort to determine what is expected to be different due to config differences, and what might actually be important.

At least I've got something interesting to stare at for a little while.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Jerry12798:
Anything you need help with? Unfortunately I'm only a web developer so I don't think my Pyhton, CSS, or HTML knowledge would help much in the development of custom recovery but if there's anything we can do I'm happy to contribute.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Vntnox:
Btw I am currently using Linux Deploy with Sparkle overlay for graphics acceleration.

Kinda convenient choice if u do not mind chroot environment.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
Unfortunately I barely know enough about Android/TWRP to even know what to ask for help with, haha. If you want to pitch in, I'd encourage you to get your feet wet and try to run a TWRP build and see if you can reach the same point that others have gotten to (i.e. blue screen). You can use the guide I posted above to attempt that. I'll be glad to help with any questions you have along the way.

From there, it seems like it's basically anybody's game at this point. Apply whatever knowledge you have to see if you can make progress on the current issue!
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Jerry12798:
Yea I've tried it but blue screened too. I know a few different devices I've messed around with before has had weird screen issues (flickering, off colors, etc) in TWRP.. I don't know if they had the sames issue we are or not but it seems probable.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
At this point, I really want to think that the issue has something to do with how we're setting up/driving the display. I'm leaning away from it being an outright problem with the kernel (and definitely don't think it's the device tree), but I do wonder if the information in the kernel logs might help us find the problem.

In comparing logs from stock recovery (where video obviously works) with logs from TWRP, I can see some notably different values getting used for initial backlight/brightness settings, as well as some other differences related to the display.

Now, I don't know that the differences I've spotted actually matter, but the display in the T870 is obviously a different model than the larger one in the T976, where TWRP is functional, so it's certainly something to check at least. For now that's all I've really got, but I'll be digging into this more soon.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Bushcat:
I can send you the log of T970 twrp and I can make los recovery and pbrp for the tab s7, maybe that has an effect because there was an effect with pbrp on the tab s7+, the tab s7+ has a small glitching strip that appears sometimes but is barely noticable but in pbrp it appears wiith every interaction, I was able to lower it but I couldn't fix it. Sometimes other recoveries work better than twrp, for example the oneplus 8 lineage recovery works better than twrp. Somebody suggested me to build the kernel inline with twrp because samsung had issues in the past, I tried with all the firmware files for our device and it fixed the timezone bug but nothing else.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
I'd really appreciate any relevant (or semi-relevant) logs you can provide, as it all gives me data to compare to what I'm seeing. Thanks for offering!
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] kabirsaad2007:
please make twrp for SM-T875 LTE MODEL
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] scriiptSQD:
@bxlentpartyon So what can I say... unfortunately, no luck for you too. First of all, I'll also give it a try and make TWRP as T870 is my main tablet now, but neither my own built TWRP nor yours worked well so far. Getting the same "Blue screen" issue, that seems none of us knows how to fix. I will try to tweak some settings here and there, hopefully, we will be able to resolve this issue.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] scriiptSQD:
We might be able to do so, but firstly we need to cope with our current troubles that prevent us from even seeing TWRP screen....

[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] :
now that i have that out of the way. i decided to flash my tablet with this and i had a different issue. instead of a blue screen it was a black screen. i can see the top of twrp but the rest is cut off with blackness. i can get an image tomorrow. i hope that the image will help
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] scriiptSQD:
It really changes nothing. Blue screen appears after you turn the screen itself off and turn it on again back...
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] RangeMachine:
So i found out that bug is probably related to pixelflinger rendering library which twrp uses, maybe someone who knows opengl will figure out.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] scriiptSQD:
How did you actually find it out? Can you give some debug steps?
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] RangeMachine:
Welp i dont have any debug steps, but i compiled stock android recovery replacing bootable/recovery folder with some fixes and it worked just fine, so looking in source code i thought its mostly like related to minuitwrp/pixelfingler. Its really giving me headache reuploading each build to my device, but i hope i will find what casues that thing. In worst case we can modify stock recovery menu and make it using twrp features.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] scriiptSQD:
You see, there is a method of debugging Android CODE via lldb while the device is running. Since every interface renderer is a process (like X11 in desktop Linux), you can start debugging it and maybe find a part of the code that may cause these issues. I'm a bit familiar with C++ and OpenGL, so I may try later. This investigation has gone really far... well
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] RangeMachine:
My investigation continues: stock recovery using bit different DRM backend for rendering, you can see it on screenshot. I did not found any public sources containg that functions, good thing they are all exported from librecovery_ui.so. So i will probably try to use that precompiled library and call exported functions.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] scriiptSQD:
DRM makes sense: https://en.wikipedia.org/wiki/Direct_Rendering_Manager
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] :
Just guessing here, since TWRP does not use 3d rendering maybe the backend can use fbdev instead? Or is that not possible?
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] RangeMachine:
Our devices dont have /dev/fb0 device which fbdev relies on. Not sure why even tho framebuffer driver compiled into kernel. I am on gts7l lte btw but pretty sure its same for wifi version.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] :
Any further details you found? I am starting to get some hope now. Good luck with the search for the graphics issue. Sorry for being so edgy witc my whole development is dead rant
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] RangeMachine:
Well no luck anymore :( I tried to use call Drm functions from librecovery_ui.so but no its just getting crashed, i will continue attempts anyway
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] :
Does CWM still exist? I know that did not need a complex interface so maybe if it is updated still maybe try compiling that for the tab s7? The recovery does not matter as long as it can backup and flash custom roms

[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] bxlentpartyon:
That build isn't really functional. I can post it again, but if you're planning on doing some further work to get it functional it's probably best to just run your own build.
[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] Sch10FNM:

[Samsung Galaxy Tab S7 / S7 Plus ROMs, Kernels, Rec] scriiptSQD:
It won't be any easier with the prebuilt image. TWRP for T870 has only TWRP CLI functional, so you have to mess with adb and etc.

I have accidentally deleted the settings icon on my screen (I swiped up too hard and fast and deleted it instead of opening it)

How can I navigate to settings without the icon?

How can I restore the icon?
[General Questions and Answers] SMcC2:
I'm able to access the settings on my device but swiping down on the notification area and selecting the settings icon.

I didn't know it was possible to delete the icon from the app drawer...
[General Questions and Answers] SatansMother:
Of course!!!!

D'oh!

Now that I have found settings again (thank you thank you) I'll go about recovering the icon to the "desktop"
[General Questions and Answers] SatansMother:
Arrggh!

I can't restore the shortcut to the "desktop" and because it's still a new-to-me phone, I like to have it there.

It is in the list of widgets, but when I try and swipe it to the desktop nothing happens!
[General Questions and Answers] Deleted member 1890170:
IMO the easiest way to recover lost or deleted Android app icons/widgets is

1. To touch and hold on an empty space on your Home screen. This method should cause a new menu to pop up with customizable options for your device.

2. Next, select Widgets and Apps to open a new menu.

3. Tap Apps. From here, you can choose the app icon that you previously deleted by mistake.

4. Hold the icon and drag it onto a space on your device. (You can rearrange it later.)

Your app should now be exactly where you want it to be, and it’ll be ready to use right away.

It's a WWE ROM as far as I can tell, haven't tried it yet.

Someone who reads vietnamese could probably tell more about it. :confused: :rolleyes:

[Touch Diamond, MDA Compact IV ROM Development] suiller:
Finally I've finished my hard test on PDAViet V4 rom and I'm not totally satisfied... I mean that this rom performs very well (like all pdaviet roms) but V3 seemed more responsive, not bad at all...

GOODs:

- very fast & responsive

- lot of preloaded software (I prefer choose between lite & full ver)

- updated OS/Xip (the latest)

BADs:

- not fast like we are used by PDAViet (V3 seemd faster)

- like ALL pdaviet roms the storage is full of unuseful things :)

- touchflo3d version (1.1x) isn't the latest one (1.2x) (bad bad boy)

- there is always the annoying bug in the videotel dialpad (why?? it's an old & well known bug!)

my verdict is (in a scale from 1 to 10): 7

By now & in my opinion the latest & fastest rom is WildBerryV1 (lite), anyway PDAViet has only full versions, so it's not possibile to make a real comparison.

Bye,
