SM-T900 v1awifi fails to install

I am hoping that someone has done this. I searched the Internet and wound up here. I have used a LINEAGE ROM in the past for an old tablet, and never had this much trouble.

I downloaded all the stuff I needed...TRWP, etc and the ROM .ZIP files (for OS Nougat and GAPPS) for the Samsung SM-T900. I downloaded the v2awifi ROM first, and it kept failing to install stating that I had a v1awifi device. I saw on the download page that there was a folder for the v1a. I got the lineage-14.1-20180526-UNOFFICIAL-v1awifi.zip file, and attempted to use the TRWP install of this file as well as the GAPPS file. The v2a file fails with some strange message that mentions something about doing a FACTORY RESET - which I did (I think). But it appears that the GAPPS installs, as when I rebooted the tablet, it begins an install of 190 apps.

I am at a loss :confused:, and asking for help. I will collect (if I can figure out how) anything that you feel is needed. I even attempted an ODIN install, but there is no .TAR file for the lineage-14.1-20180526-UNOFFICIAL-v1awifi.zip file.

I have been at this for hours, and even have ROOTED the Tab 12.2, did not seem to help. There is nothing really on here that I wish to keep, as it is brand new. It will become a home automation tablet (mounted to the wall with ACTION TILES) once I get it updated. I had to read between the lines for some of the installation instructions. The tablet has no SD CARD installed. I copied the .zip files to the DOWNLOAD folder on the tablet. If it is necessary to use an SD CARD, I will have to get one. The old one I had went 'boom' after about 4 years of use on the old tablet...which I reset and gave to GOODWILL.

Any suggestions are greatly welcome and appreciated.

Much Thanks,

*BH*

You need to install the v2a recovery from the first post.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] bearhntr28:
I do not want to sound stupid, but I must be blind. I followed the instructions from the first post, and I do not see a v2a RECOVERY there. When I followed the instructions - and used the v2a files, they failed. Stated that I had a v1a.

Any suggestions?

On the back of the device, what model do you have? If you can't find it there, the next easiest thing to help determine is do you have the spen or not.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] bearhntr28:
thompatry,

OK. Went back and re-read the post, and I see that I missed a download. I was able to get the v2awifi-recovery.tar, got it to install, and the SM-T900 flashed with the v2a image.

Thank you for the knock in the head. :D

Now let's test this puppy out.

To all the input from the forum. I got all loaded, and booted up, through the wizard, and all seems to be running smoothly. Trying to decide if I want to ROOT it - then figure out the specific to doing that.

I believe that I the only way to remove SOME of the apps that I will never use.

Gonna have see what this DEATHLY ADIUTOR app is and play around with the OS. This tablet will eventually be hung on a wall in my kitchen for SMART HOME CONTROL panel. I was gonna get the GALAXY VIEW 18.1" tablet, which would have been AWE-SOME, but I have seen no ROMS for it and it also is locked at 5.1.1. I have an SM-T800 which I will have to find one of these ROMS too. Then the 12.2 and 10.1 will match.

Also is there an easy way to switch between the launchers?

A Million thanks. Great Work.

Thanks for this initiative, I'm happy to run Lineage-14.1-20180602-UNOFFICIAL-v2awifi now!

Some observations;

- Can it be that battery charging is much slower then on stock Lollipop?

- Menu and back buttons brightness can be reduced, but never switch off after x sec. of inactivity

- Q: Will I receive Lineage updates automaticaly (over air?)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] thompatry:
Go into Deathly Auidtor and change your charging settings.

Hi,

I've been reading the majority of the posts on this thread with interest. I'm looking at buying this tablet and first thing I will do is install LineageOS so that I will have the latest OS. However, one of my primary uses is the S-Pen as I make lots of notes. I couldn't see anywhere in this thread how the S-Pen is working. Can somebody be kind enough to post some details of how it performs? I currently use the SNote app on my Tab A and really need a physically bigger tablet. I am also considering the iPad Pro 12.9 with the Apple Pencil but to be honest I'd rather stick with Android.

Thanks

apk compatibility

hello,

first of all thank you for the rom, great work.

I just noticed that some APK dont recognize the tablet correctly, as netflix who says "not compatible with the tablet" and you have to force install with external .apk.

In some others APK like molotov, the tablet is not recognized and the TV stream is received in lower resolutions than before.

I dont know if its possible since this tablet has never been officially updated to 7.1, but it would be nice if it was recognized as what it is, a powerful 12.2'' screen , 7.1.1 tablet

Edit : ok sorry I just found my answers in many articles about netflix and L1 security level needed. Its very annoying :s I m a regular netflix user so i cant use this rom :'(
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] WangChung81:
You can use Netflix, just have to use Magisk and use an external APK not from Play Store. Only thing is you won't get higher than 720p quality, but I definitely watch Netflix every day on my T900.

In other news, I can't express how much I love this ROM and the regular updates. Appreciate your hard work OP!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] shima_momy:
This big screen tablet for some reason thinks its a phone, so all apps include play store are using Phone mode (portrait mode, if in the landscape mode they will add bars to both sides). Please fix this OP. it wasn't like this before but I cannot remember what update this issue started.

Hey love that someone has taken the time to revamp this tablet. I'm currently running the 3/24/18 version because anything beyond that causes severe screen flickering and eventually crashes. The game "Ascension" is unplayable, it flickers like a strobe like then restarts the tablet. Multiwindow mode works great unless you're wanting to use it with chrome (ex: using word and chrome at the same time).

I'm sure these are all things that you have read before. Browsing the forum I downloaded the newest SU 15.1 and it says that I do not have root access, though apps and adb are selected, "managed root access" is greyed out. Flashed back to the version 14 and everything is working again. Wasn't sure if that was a problem because I'm not using the August update or what. Another issue I've had with updates after 3/24 is CPU usage skyrockets and stays at anywhere from 60-80% without anything running but background processes. Would there be any tips to lower that? I'm a nub when it comes to custom roms. Any helps appreciated TIA.

You can install an app called Rotation Control (Play Store Link) that fixes 99% of these regardless of update. My ecobee app was displaying portrait only and this fixed it into landscape. Luckily in 8.0/8.1 there's a built in rotation control so shouldn't need a separate app.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] WangChung81:
Only two issues I've run into through several revisions, don't know if it's a ROM thing or an app thing:

- Hangouts crashes when trying to use video chat (front or back camera), audio chat works just fine. Google Duo works just fine for both audio AND video, video recording also works fine as well.

- The 'High Touch Sensitivity' option eventually crashes and reboots the tablet. GPU is not overclocked or off its stock governor via Deathly Kernel Adiutor. CPU governor is set to 'Performance' as the tablet is always plugged in.

Oh, any chance we should be using Kernel Adiutor instead of Deathly? Deathly hasn't been updated in almost a year and a half.

hi the severe screen flickering and powering off happen to my old Samsung tablet and now my galaxy tab pro the problem is that since these are very old tablet the battery is dying and needs to be replace once you replace your battery the flickering should go away good luck. :)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] RedWingsFanEd:
I had the flickering issue and assumed that it was the battery but after I installed the update from the 18th of August, it went away. I have resisted the temptation of installing any new update :)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] shima_momy:
Yeah, this sorta fixes some issues but not all; stupid Reddit app uses phone layout and even if you get it to work in landscape the texts and pics become so big and huge that is unusable. What needs to be done is that from ROM base 'Tablet mode' or some sort of Landscape mode set by default.

---------- Post added at 01:06 PM ---------- Previous post was at 01:04 PM ----------

OP please fix the issue of Tablet/Phone mode (this rom is using phone layout, just check playstore and you'll see bars on the side) in your Oreo update along with adding patch notes so we know if we want to update to latest patch or not.

Keep up the good work mate.

I keep getting bootloop with anything above the July updates. It doesn't happen right away, but for some reason it happens around a month or so of usage. Oddly enough I've posted before about screen flickering and restarting too. I didn't install full Gapps this time and my cpu is still low and no heating issues when playing the game "Ascension" that I was previously having a problem with too, no screen flickering or restarts either.

Running July until they decides to release Oreo. Seems the most stable for me but I can't say the same for others.

Saw that the bootlooping stuff got fixed a couple weeks ago so I've switched to this from 9/26/17 RR 5.8.5.. Very solid upgrade! Only thing I've noticed in a couple days of use is that sometimes the screen auto-brightness is def on drugs, otherwise everything has worked flawlessly. Excellent battery life, picture looks sharper?, it's less laggy.. I love it. Running magisk, nova launcher prime all blacked out, SwiftKey nickel kb, everything looks great and functions flawlessly. I'll test screen mirroring at some point, that's always a good test.

Moral of the story is.. Thank you for all your time and effort. I don't like replacing devices simply because there is something newer, through the power of your software wizardry, this tablet is still very much an awesome piece of hardware.

==> Maybe this could be changed in OP

Where I stumbled was that I needed to boot into recovery right after the 'TWRP.tar' flash with Odin.

For this I deactivated auto-reboot, shutdown after flash and booted with Volume up+Power to get into TWRP.

==> Maybe this information helps someone

Very nice to finally have a usable system again on the tablet! Many thanks to everyone involed building this rom!

just a short Question: will this fit without repartitioning?

Because for the newer version of Oreo I had to repartitioning my Samsung Smartphone GT-N7100 - but luckily

we (GT-N7100 Users = Samsung Note2) got a flashable .zip which did the job :good:

So if we are need to do such a thing it would be fine if we could also use such a flashable script for repartitioning :)

hi

I just installed lineage-14.1-20181027-UNOFFICIAL-v2awifi.zip

My first tests are very conclusive: fluid and fast.

Especially since I started from afar: official rom Kit-kat.

Some information was missing : installing TWRP with Odin : click on the AP tab on Odin window and select the TWRP recovery .tar file that you downloaded for your device ( source )

Connecting the SM-T900 in download mode : windows detects a "gadget serial" and is unable to install driver. Driver is from Samsung and was hard to find ( here )

Out of that, I had to reinstall a full windows virtual machine under linux, because heimdall under linux is not working for installing a bootloader.

But these are details, and I thank you very much for your work and follow-up.

Had that flickering issue on two SM-T900 tablets. Both times it was no software or battery problem but a faulty battery connector. Just google for "galaxy tab 12.2 battery connector", you will find several YouTube videos showing how to fix this. I repaired both tablets by only resoldering the connector to the pcb, after that no more flickering appeared, battery working for 8-10 hours video playback and recharging way faster than before the fix.

Before the repair i thought some releases worked more stable or with less flickering problems than other (older) weeklies, after the repair i can for sure tell you it doesn't make any difference.

If the battery connection is somehow faulty strange errors occure, as there were flickering black screen, battery dropping from 30% to zero within seconds, battery heating up, charging needs double the time than normal, and so on.

Hi,

Thanks for supporting our tablet!

All but one was working. This one is very important to me, because i use my tablet as TV in bed at night ;)

-> I could not turn off soft key lights.

When i set the settings to 0%, the buttons are still on at very low light.

They are not completely off. They also stay permanently on.

I had to select "reset settings" (100% and off after 3sec) and then the light goes off after 3 sec.

Why is there not selector to turn them off completely (not 0%) ?
