Any opinion?: firmware choice: Samsung Galaxy Tab S2 SM-T810 [moved from Android General Q&A]

I'm looking for best bets for choosing a good firmware update for this older SM-T810 tablet that I still like. It is Wifi-only.

The tablet recently got very flaky on Android 5 so I let it install an auto-downloaded image for Android 6. The new image probably came from Samsung since I was told at purchase that device had official Samsung firmware for Android 5.1.1. (see ABOUT DEVICE below)

Things got worse using the new Android 6 image, so bad that I'm ready to install new firmware by sideloading.

1. Since the device was rooted by prior owner (see: DEVICE HISTORY below for details) I am guessing I have little to gain by sticking with an official Samsung image--unless nothing else works. Does that sound right? And, does anything prevent me from going the non-Samsung route?

2. If it makes sense at this point to try a non-Samsung image, my question for folks here boils down to this: where am I likely to have the best luck finding a build that will work well on the device? For example, I wonder

who are the most experienced makers of firmware for this older tablet?

and which version of Android--7 or 8? Should I avoid 8 or go for it?

(I've seen an unofficial Lineage OS build for Android 8. I believe that Android 7 builds exist, too.)

Thanks for any suggestions.

____________________________________________________________________________________________

MORE:

(I've waited so long to update because a) I seldom use the tablet and b) seller said that he'd had problems with a German Nougat and had reverted to official Android 5.1.1. )

I bought in 2017 on swappa.com. Seller told me "What you would get out of the box is the official Samsung OEM firmware for Android 5.1.1 (XAR-T810XXU2BPB1-20160323135521) with the official Samsung recovery. Updates will apply without issue, either by directly loading with Odin or SmartSync, or doing an OTA firmware update....It is running pure stock firmware now. Since it was rooted at one point, the Samsung Knox flag is tripped. It's the only thing that would distinguish this device from a new-in-box tablet."]

I'm not a developer, so I couldn't think of a reason to install Linux on DeX. Until I noticed there was a Linux build for Calibre. I use Calibre on my pc to manage my ebook library. There is, of course, no Calibre build for Android.

Does anyone know if Caliber will run on Linux on DeX, and if so how well it works? Could it replace the Windows version? Would it be worth installing Linux on DeX just for Calibre?

Thanks,

Joe

[Samsung Galaxy Tab S4 Questions & Answers] Erayd:
I have tested it (latest available LoD and fully updated Ubuntu 16.04), and can confirm that while it's available in the arm repositories by default, it doesn't work on LoD. Instead, it simply hangs on startup.

Looking at the console output, this seems to be a shared memory issue with QT, so it's unlikely to be an easy fix.

[Xperia Z5 Compact General] apsommer:
In my persistent attempts to put a custom rom on this device, the following sequence occurred:

- Phone suddenly not recognized by PC in any mode: normal, recovery, or fastboot. It would not even charge from the USB port, no reaction at all from the phone or PC that the connection is made. Other devices using the same port and cable work correctly.

- Phone unresponsive to a wall charger while it is powered on. Similar to the above description, the phone does not recognize that it is pulled into a charger at all while it is powered on. However, at this point the

- Phone is responsive to a wall charger after turning it off. The screen shows the charging icon on screen and the LED is red, meaning the phone recognizes the micro-USB connection when it is powered off, but only via the wall charger, still sees nothing when connected to the PC.

With the above criteria I decide to let the device completely discharge its battery, hoping that a full empty to full charge will reset whatever is happening. It takes about 3 days to go completely dead ... moving from screen need-charging image, to only the red LED, to absolutely no response when pressing the power button.

Now I have a phone that is completely unresponsive to any button press, as expected since the battery is completely drained. Unfortunately, it no longer responds to the wall outlet at all. Meaning it won't charge in any way. Used multiple chargers, multiple wall sockets, multiple cables, gave it compliments, etc.

At this point the phone is totally and completely dead and unresponsive to any charging. Any thoughts or help? :(
[Xperia Z5 Compact General] Wenro:
I had this issue when trying to flash GreenKernel. Turned out I messed up on a step and flashed it the wrong way. Check my posts in that topic.
[Xperia Z5 Compact General] apsommer:
Thank you for the response, I was about to throw the phone away. :( Can you be a little more specific? I see your post here regarding a rebooting loop with red light flashing. However, I don't have any response from the phone whatsoever ... nothing on the screen, or led in top right. It does not accept a charge from 1A or 2A source, it is literally a paper weight right now. I need to "jump start it" or something of this nature. It won't charge at all.
[Xperia Z5 Compact General] antonio.galea:
Probably the phone looks dead but does get charge - it's just not showing it with the LED.

I believe Snapdragons are close to impossible to hard-brick - the chip itself has a ROM with EDL burned into it and that can always be used to bring it back from zombieland, if you have the right tools. But if you are lucky enough, then service mode would still be available even without hunting for the EDL stuff.

First, power the phone off for real with the hidden button near the SIM tray - and leave it off.

Then, install Flashtool and use it to flash a stock ROM, as described for instance here. When flashing, choose flashmode instead of fastboot and follow the instructions.

HTH,

Antonio
[Xperia Z5 Compact General] apsommer:
Thank you for the response. I pressed the hidden button in the SIM tray for 10 seconds, 3 times in a row. Downloaded the latest "Emma" Sony Flashtool ... and nothing happens. The software does not recognize any Sony device plugged into the computer. Checked the USB cable, it's good. The computer, and the Sony flash software, do not recognize the device at all. It will not turn on in any way, and it does not appear (based on the screen and LED) to accept a charge at all. It truly seems bricked at this point. Any thoughts? :(
[Xperia Z5 Compact General] antonio.galea:
I don't know what method is used by Sony Emma, sorry. But simply connecting the phone won't surely be enough if there is no software on it that answers to USB requests from your PC.

How about trying with the tool I suggested you? Let the phone off, download a stock firmware and start the flashing in flashmode instead of the standard fastboot mode (just follow the on screen instructions).

If that does not work, the only thing that's left is EDL mode. I've found no documentation for Z5 Compact, unluckily - but any decent repair shop should be able to resurrect it.

Antonio
[Xperia Z5 Compact General] apsommer:
I downloaded the flashtool you linked, and also the XperiFerm and latest Z5C drivers as mentioned in the tutorial. The drivers do not have an exe. I can not manually install the drivers because the device is not recognized by the PC at all, it does not show in the Device Manager. Moving forward ... downloaded and installed the Sony Xperia Companion software, it also does not recognize the device at all. The flashtool you linked also does not see the device at all.

23/016/2019 00:16:53 - INFO - Device disconnected

There is no flashmode or fastboot mode possible, the device does not respond to any buttons, any charge, or mean glances. Any last thoughts before I cut my losses and throw it away for a XZ1 compact?
[Xperia Z5 Compact General] antonio.galea:
Don't throw the phone away!

I fear I was not explicit enough:

1. keep the phone off and disconnected

2. click on the Flash icon, choose the firmware

3. choose flashmode

4. press volume down and only then connect it to the PC

If even this alternative service mode has been wiped, then the only possibility left is EDL. For that, I'd go to a repair shop.

Antonio
[Xperia Z5 Compact General] Raphos:
Hi,

Power off the phone : press volume up and power button. Wait 3 vibrations (if not, the phone is powered off).

Press first the volume up and plug the phone with the usb cable into your computer. If you see the blue light you can use Flashtool, if not... it's dead (for me)...

How to use Flashtool is another thing, blue led is essential.

You'd rather throw it away for a Xz2 compact and install Omnirom. You can find some used ones for good prices.
[Xperia Z5 Compact General] apsommer:
Thanks, Antonio. Step #4 causes no reaction in the phone, or the Flashtool. The software does not recognize the device and the phone remains unresponsive. It truly seems hard bricked to me. I live in Mexico ... this device is rare even in the US, the guys will have never seen it, and their approach to EDL is as good as mine. I'm pretty frustrated with this dead phone, I think it's time for a new one and to mark this as a lesson learned.
[Xperia Z5 Compact General] apsommer:
Thank you. No blue light under any button combination, charging cable, outlet, software, mean glances, etc. My next one is XZ1 or XZ2 ... I'll take your advice into consideration, the XZ2 has better specs but of course its +$100. I like to think of myself as a capable engineer, but destroying this Z5C has made me pretty hesitant to attempt the same process on a new phone. Everyone seems to agree that hard bricking this device is near impossible, however I beg to differ as look at this dead one on my desk.
[Xperia Z5 Compact General] antonio.galea:
Ouch - a real pity.

It really seems you succeded in wiping out all possible accesses for the Sony bootloader. Do you mind me asking how you managed that? I'd like to avoid doing the same mistake.

Qualcomm EDL mode is surely there, but you will need to open the phone and the software for that approach is not freely available (or at least I was not able to find it).

Antonio
[Xperia Z5 Compact General] apsommer:
I don't remember the exact sequence, but "fastboot erase" was used on the "bootloader" and "recovery" partitions, then the phone was unplugged. This left the system with no start sequence ... when I depleted all the battery charge it simply wouldn't respond to anything and has since been lifeless. I'll pry it open and take a look at the internals just for fun and to get one last squeeze of value from it. I also plan to bash it with a hammer which will be particularly satisfying.
[Xperia Z5 Compact General] antonio.galea:
You can safely overwrite boot, but never ever touch the bootloader. The bootloader is responsible for starting all the various programming modes, as well as passing on execution onto the kernel start during normal boot.

BTW, I don't think there is any reason at all for erasing partitions - when you overwrite them with your own data they will end up being clean anyway.

While I can understand your frustration, that would be quite silly. Even if it has no value to you, it's still recoverable for anyone with the skills and tools - try to sell it instead, if anything it could be used for spare parts.

Antonio
[Xperia Z5 Compact General] apsommer:
Yes, I learned my lesson with "fastboot erase bootloader". I'd be happy to sell it for parts, what website would you recommend for listing it?
[Xperia Z5 Compact General] antonio.galea:
I'm trying to find out more information about the emergency recovery mode for Z5C - I might be able to find out a way to recover your phone. If I'm successful (be warned, it's a big if - so please don't count on it), you could sell it as a working phone instead of as a brick.

First problem, I don't know how to enter EDL mode on the Z5C: but I hope an EDL cable could work. I've ordered one for testing, since it's an useful tool for recovering a lot of other phones too - it will take a while to deliver, so don't hold your breath. You could also join me in my experiments (after all, you have nothing to lose) by ordering one yourself (you can find cables for as low as 3$).

Second problem, the software tools. Given the ubiquity of Qualcomm chips, apparently there are quite a few available. In the opensource arena, I've found those:

https://github.com/96boards/documentation/blob/master/consumer/guides/qdl.md

https://github.com/openpst/sahara

https://github.com/bkerler/edl

Third problem, finding the signed binaries you have erased from your phone. I guess they can be extracted from my own device quite easily - they are on eMMC after all.

For an in-depth discussion of EDL mode, geared towards its (in)security, I've been reading Aleph Security articles here.

Antonio
[Xperia Z5 Compact General] Wenro:
Hey again, sorry for late reply. Work...

My issue seems totally unrelated to yours. My problem was that I was doing the flashing wrong, instead of just flashing the entire .zip I flashed boot file etc and this is what started the issues with not taking charge, BT wasn't working, wifi etc. But I had more juice in the phone since you want to have quite a bit before doing flashing, but I read your post about discharging it.

If you can't revive it, don't fear rooting and flashing, just make sure to read and to take all steps necessary. I kinda messed up my Z1C and I didn't do any changes to my Z5C until recently. Well, maybe a year now, just because of that occurrence.
[Xperia Z5 Compact General] apsommer:
Wow, you're a true engineer, never give up! Consider my phone part of your testing devices. Please confirm this is the correct EDL cable to purchase for the Z5C: EDL cable for all Qualcomm phones ... It will take a few weeks to get in my hands.
[Xperia Z5 Compact General] antonio.galea:
Hello, got my cable - but I've not been able to make it work so far. It could be because I need Windows and specific drivers, I'll look into some more. But yes, when it's fun I never give up ;)

[General Questions and Answers] drewbuckleydb:
I'm hoping someone may let me know if it's possible to write a Driver to access the Android Cameras' directly rather than the OEM's or the Camera API?

I'm looking to have an app that can access both Front and Back cameras at the same time for devices that have dual video processors and looking to hire a developer to do "this" if it's possible.

I imagine it would most likely be C++ at the Linux Kernal or HAL level?

I'm not sure if there's anything at that level that would prevent an app from using it's own driver either?

Android 9 now allows for Dual/Multi Camera support but at that higher level, the Camera2 API only works for some devices. Have tried on Galaxy S4, S6 and S9 all running Android 9 and only the S4 worked.

Any information would help me to see if it's worth pursuing and greatly appreciated.

Hi,

Just got myself a Mi9 its got the 10.2.6.0 Global firmware on it. This issue i am having is the app notification sounds for specific apps, it seems like they are all just using the default notification sound and i cant find where to change it.

For example, on my old Mi6, when my Ring Doorbell would detect motion, the app notification would play a windchime sound, and when someone pressed the doorbell, the app notification would be a doorbell sound.

But on the mi9 all im getting is whatever is picked in the default notification sound in the settings of Miui.

Is this a bug or is there a setting i can change?

Hi Guys,

Ever since me and my wife updated to 9.0, we have been having issues with calling. Caller on the other side cannot hear unless we reboot the phone. Never had this issue during oreo. It's kind of strange that both of us are having the same issue.

This will happen 2-3 days or sometimes a week after reboot out of nowhere. Unless I reboot, other person cannot hear. However whatsapp calling works. it's definitely not a mic problem. Anyone has the same issue or know how to trouble shoot? To reset the phone is one option. I have disabled all apps that Huawei automatically kills due to their stupid battery saving feature. But it hasn't really helped.
