Custom ROM for Samsung Tab S SM-T807R4 - Android Q&A, Help & Troubleshooting

I have a Samsung Tab S SM-T807R4 that I’d like to install a custom ROM to. I’ve used ODIN and rooted the tablet. I just need to find out what version of TWRP will work on it and most importantly, a custom ROM. I’ve done a lot of digging and I know there aren’t very many of these devices in the wild so there’s not much support for it. Is there a version of Lineage OS that will run on it? If not, are there any alternatives? I’ve got that annoying screen freezing problem and I don’t really want to go back to lollipop.

I don't have this device myself but, the following area of the forum is specific to your device and variants.
https://forum.xda-developers.com/galaxy-tab-s
From what I've found, the SM-T807R4 has a Snapdragon processor and the Bootloader for all the Tab S devices with those processors cannot be unlocked (so far).
Thus you cannot install a Custom Recovery resulting in the inability to install a Custom Firmware (ie. LineageOS).
At the moment, the Bootloader can be unlocked ONLY for the Tab S devices with an "Exynos" processor.
Sorry for the bad news...
I do wish you the best of luck!

[Q] Android Devices Currently Not Supported By Cyanogenmod

Hello Guys,
Could anyone please provide some info about this case:
o What are my options if I have an Android device (smartphone) not supported by CyanogenMod?
o Is there anything than waiting until my model will be added to the supported list? I bought a very simple and reasonably priced "no-name" phone (Simvalley SP-2X.SLIM), and I learn now one disadvantage is that it is not supported.
o I also did not find anything about rooting, flashing or even booting it up into safe mode / recovery.
Any help and info is very much appreciated.

Hy there, you can try TWRP Manager. It's a similar program

Well, here it is straight forward, your device only gets official support if the Cyanogenmod teams deems the unofficial build for it stable and reliable to gain official support. If there isn't any unofficial builds then it's safe to say that it will never have official support. As for rooting the device there may be methods for it available, a universal root for example, flashing as in roms and other things, no clue, never heard of that device before and there might not be any support for it either. So with that being said, hope this helps you.

Hi Yoelpro,
Thanks for your info. Since my first post I have managed to root my device - was very happy. It was not too easy, given that it is extremely minimal supported. I already tried TWRP with GooManager, but when I try to install an open recovery sript, surprise surprise: "no recoveries were found for your device".
Any ideas if there is another way to find one and copy it on the phone? I have to confess being too scared even trying to flash a custom ROM without flashing a backup first. I managed to find out that the stock ROM is a Vanilla on my Simvalley SP-2X.SLIM.
Thank you.

Hey there Critical Detox
Thanks for your info. Since my first post I have managed to root my device: Simvalley SP-2X.SLIM - was very happy to see that it is working.
Unfortunately, I could not even find an unofficial CM build, I'm quite sure that an official build does not exist. Interestingly, my device was once perfectly recognized as SP-2X.SLIM and once recognised as HTC (for drivers) during the rooting. I'm very curious IF or AS WHAT my device would be recognized if I started the one click install of CM. I might be a chicken, but a careful chicken as I don't want to do it before saving a backup of the stock ROM to my SD card first. When I try to install an open recovery sript (GooManager), surprise surprise: "no recoveries were found for your device". I managed to find out that the stock ROM on my device is a Vanilla 4.2.2 but could I not find this ROM to download yet.
Any help is very welcome, as I am not quite an expert and my phone is a quasi no-name model.
Cheers,
schmayer

Will Remix OS boot on x86 android tablet? Answer is unclear? Help

I am a Asus trio tx201la owner and were completely upset that asus offered no other updates beyond android 4.2 to the tablet part. I noticed that samsung did the exact same thing with the samsung galaxy tab 3 10.1 and so did Dell on the venue. The venue and the galaxy tab 3 have same intel atom z2560 cpu soc and is stuck on android 4.2.
Unlike the Asus Trio the Galaxy tab 3 got a lot more attention and thus a lot more custom rom attention.
The galaxy tab 3 has been updated to 7.1.1 with custom rom by linage OS see:
http://techbeasts.com/install-androi...lineageos-141/
Now How can that help the Trio. The Trio has the same soc and is detectable by the intel platform flash tool released in 2017:
https://01.org/android-ia/downloads/...lash-tool-lite
Stock 4.4.2 android provided by intel: https://01.org/android-ia/downloads/android-4.4.2r1-ia2
Then I found a guide on how to use the tool here: http://www.aryk.tech/2016/04/how-to-...ing-intel.html
So I thought I was off to the races to make the update. The problem was I needed a flash.xml and fake the galaxy tab 7.1.1 update onto my tablet but no where could I find this file and certainly not one meant for my tx201la tablet. So I was stuck once again with no update path.
Then I found Remix OS and thought I had something but nope, again I cant find any info on how to get remix to boot on a android tablet? Ive also looked at running chromium OS on my tablet but that update path also seems to be blocked. So is there an answer or is my x86 android tablet dead?

First, you do not want to flash the Galaxy Tab 3 ROM, since while they do share the same CPU and chipset, the same can probably not be said about the rest of the components, from the screen to speaker(s) to the vibration motor (if it has one), so you may well be left with a tablet that barely functions.

About Remix OS, it depends on whether you have a standard EFI (yes, there are 32-bit EFIs) or BIOS, or rather an Andtoid bootloader like most ARM Android devices.

Why is running Chromium OS not an option for you?
Could it be related to the BIOS/EFI/bootloader?

On the galaxy tab 3 consideration, doesn't android use a generic display driver making this possible? I get how some of the parts could be different but it would seem that generic driver support may fill in the gaps, no? Apparently I could get there with MultiROM and see if it at least will boot. It may not I guess. Am i just wasting my time?
Chrimium OS would be great the problem is how to. I look into getting chromium os onto this tablet but all the info was related to installing on a intel pc with a bios. My tablet has android bootloader and I guess that is the big problem. However it seems that if you have root access it should be possible to change the boot kernel that loads or is that not possible? Gentoo is linux just like android so it should be possible to bypass the boot process somehow. Any how to's to do this? Ive googled to no end and it seems all the pieces are there but not any connection between them to run on a z2560 soc like mine.

In terms of display driver support, while ignoring the rest of the hardware, it depends on how the ROM was compiled, and even if you manage to get a picture, unless the screen gets properly detected, you'll only get a resolution of 800x600.
Plus, the touch sensor on the screen requires a completely different driver, to which, as far as I know, there is no standard.

The Android bootloader is based upon Coreboot, however it is specifically built to only boot system's that adhere to Google's boot procedure standards, so while it is theoretically possible to boot any Linux distro with it, you'll need to find one that was specially compiled for it.
The BIOS and EFI utilize completely a different standard, which means that to get a BIOS/EFI complient system to boot, you'll need to completely replace the bootloader, regardless of root or custom kernels.
And unless someone had already compiled one for your device, you're looking at a feat that is way above most people (even experienced enthusiasts), since this is goes much deeper than the OS.
While in my opinion, the time spent researching this is definitely worth it, unless you find a custom-built BIOS or EFI, or you learn how to build kernels and ROMs (the latter is easier), your tablet is pretty much stuck at where it is for the time being.
That said, I prefer to look at this kind of situation optimistically, without deluding anyone.
The current situation may be rather bleak, and the chances of getting out of it may be slim at the moment, however they exist, and they are slim at the current moment, nothing given about the future.
While we shouldn't get high hopes, we must not extinguish them either.
Thanks for the info. Ill keep looking. I bet some amazing hack will come out in the future to bypass the boot process. Multirom already sorta does this, so the least I can do is test it.

I too am sure of it, however I try to be wary at the same time.
I'd like to point you in the direction of Coreboot and Libreboot for information on some of the possibilities.
I'll check them out..
Update: looks like there sorta replacements for a bios. Maybe the devs will attempt an android bootloader port.

They are open-source implementations of EFI, SeaBIOS is the BIOS equivalent.

Yeah I'll look into it. Since Asus also made a tablet only tx201la called the tx201laf (released only in France) could I use the Intel flash tool to flash it's Ron? See: https://www.asus.com/supportonly/TX201LAF/HelpDesk_BIOS/
At least it's an update to android 4.4.

Gave it a shot with standard update procedure & no go. Says hardware ids don't match. I can't use Intel flash tool cuz Asus image is raw format with no flash.xml. so I'm still screwed.

I'm by no means an expert, however I may be able to glean some information from it that may help towards building one for your ASUS tablet.
Unfortunately that is what stopped me from flashing the galaxy tab 3 linageos image on my tx201la tablet, there is no flash.xml included because you need to flash via custom recovery.

XCover Oreo 8.1 ROOT
My XCover 4 updated to Oreo 8.1. I'm so sorry that I didn't stop the upgrades from the stock Nougat ROM.
As far as I read Oreo updated the bootloader to version 2 and it doesn't allow downgrades via Odin back to Nougat. I wanted to flash a Baltic Nougat version of the ROM so that I could run a CF-Auto-Root for the ROM that I found in a tutorial online.
I also tried to get TWRP installed with an xcover4 image from TWRP Builder, but I doubt the bootloader version is the same and my phone doesn't even show up when I run "fastboot devices" when in bootloader mode. It shows up in "adb devices".
My main reason for rooting the phone is so that I can get call recording enabled.

LG LM-X210APM20s (Phoenix 4)

Hey all,
I got this unlocked GSM phone from a very large online retailer and I would like to put TWRP on it and also flash a custom ROM and possibly gApps if possible. I came across a guide telling me to download an app to determine if the phone supports project treble, which it does not as it was upgraded to Android 8.1.0.
When these devices are advertised as unlocked I assume it relates to being free to use on any carrier using that particular network, in this case GSM? Also, this does not mean the bootloader is unlocked?
I am having difficulty in finding the correct version of TWRP for this particular device as well as compatible custom ROMs and I am not even sure that this is the correct forum to be posting in for my device as I didn't see a Phoenix 4 forum. Please help.
Any chance a mod could transfer this post to the correct forum?

Question why the community for edge 30 pro is not that active?

5 years ago when i got Moto g5 plus. its community was very proactive in terms of ROMs and stuff, but that is not the case here with edge 30 pro, is it beacuse the phone is not that popular or its new? coz i am thinking of getting this or the upcoming moto frontier but since moto only supports the device for 2 years, i want to root my phone and install a custom ROM on it. does anyone know if the custom ROMs will be availabe for it anytime soon, and also if anyone can make a tutorial about rooting the phone, that will be very helpful. Thanks
The phone is new, not that popular, and motorola doesnt make it easy for custom roms either. We can probably count on some more popular ROMs like LineageOS as more people get the phone and demand rises.

thank you, but i dont think lineage OS will be better than the stock moto UI, i still love my moto g5 plus due to its support. Motorola should either provide atleast 3 years of supoprt or make the unlocking and installing TWRP easier. also one more thing i didnt saw TWRP installation in the provided link is it due to Motorola being more strict??

TWRP itself is on the decline since Android 10. Magisk-patching boot manually has become the more universal rooting method.
