Whew...thanks, I was able to use MTP on TWRP to copy over the LoS 20180526 zip, and it looks like it installed ok. Apparently I did erase the system partition.

Now I'm trying to restore my latest TWRP backup (before all this happened)...apparently it needs to be on the internal storage, and not on the SD Card? Selecting "Restore" in the TWRP Recovery menu doesn't find my prior back up files.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] supachris:
Maybe there is somthing wrong with the SD card. Backup all data and re-format in Android. This can help.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] hamudistan:
No, don't do it. Twrp 3.0.2.0 can't see your external sdcard. Higher versions can, but end in bootloops amd other faults.

Only solution is to copy files to internal sd with rootexplorer and clean up after flashing, to not let your internal sd run full
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] gandoe:
Yes, that's a good idea. I did manage to restore my prior TWRP backup of 20180402, only to realize that I made that while still on CM12, just prior to switching over to LoS 14. So, I simply re-flashed LOS 14 20180526, and then plan on wiping the system drive, and then reformating the SD card, and then doing a clean re-install of apps before making a clean and updated TWRP backup and Ti backup. My bad for not having a clean backup!

Thanks all for the suggestions and help

Ah...thanks for that piece of info. So, if I continue to use TWRP 3.9.2.0, I'll need to keep both TWRP backup and a flashable zip on the internal sd

However, when booted into LoS 14 / Android 7.1.2, the tablet indicates that:

- a prior SD card is missing

- there is a new SD card which is in the "portable" format, not as internal SD card.

I'm assuming this is a resulting of restoring a backup with CM12, then reinstalling LoS 14. I seem to remember a similar issue two months ago when I first installed LoS.

In any case, as stated earlier, I think a clean wipe of everything (system, cache, sd card) then rebuild a clean system.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] gandoe:
Curious - so I've got a clean system now, with TWRP 3.0.2 and LoS 20180526 and after wiping all partitions (sequentially!).

Now, however, after successfully booting into Android 7.1.2, the Tab indicates that there is a new SD Card, but when I select either format option: "Portable", or "Internal Storage", the format operation fails with error msg:

command "13 volume partition disk 179:32 private" failed with '400 13 command failed

Is this a function of TWRP 3.0.2?

It appears that TWRP 3.1.1-0 causes random reboots. Is the new TWRP 3.1.2 more stable?

Otherwise, how can I format the SD Card for use as "internal storage"

TIA

Hey can you inform me about the battery performance on last updates??
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] gandoe:
While I don't have hard data, I will say that both battery performance, and computing performance, were significantly and noticably increased on LoS 14.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Richard60:
I replaced the battery for a original new one. Problem is that it does not load more than 85%.

How to calibrate of fix this?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] hamudistan:
Let the tablet run until it shuts down by itself. Ignore power warnings and don't plugin charger before tablet has completed shutdown. Charge full, unplug and boot tablet. Your battery is calibrated now
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] chr0m:
Is it normal for this to perform really sluggishly on the n2awifi? I'm guessing it's the 2GB of ram slowing it down.

Is there a rom that runs a bit snappier?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] van_gogh:
Stock ROM.

It just old now
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] amphi66:
I find the last Resurrection ReMix (Android 5.1.1 HERE) for picassowifi is still perky and works fine.

None of the later ROMs work as well, although LiquidDeathOS was very nearly there.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] van_gogh:
A big thank you for amazing work! Guys who installed the latest version: do you still see Settings and Browser crashes? Thank you in advance!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Pipeman597:
After doing a dirty flash over last build my tablet was unusable. I did a clean wipe install and the tablet works fine now. The only thing I see is that the battery usage displayed is erratic. It will sometimes show a rapid discharge then upon reboot it jumps back to normal. Maybe it will correct with more usage? Thanks for your continued work this ROM is great. :)

After dirty flash..

Perhaps some fake stats-files is in batterystats.bin ...you can use some calibration battery app from store & perhaps it corrected (need root & not sure but u can try) sry for english
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Starlord:
You need to do battery calibration. Random battery percentage drops can happen after flashing a custom ROM.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Pipeman597:
Yes the battery level is now working correctly. Thanks for the responses. On another note the mic doesn't work in Skype for me. It is working for Google Now. I know that there is still issues with the audio I am looking forward to new builds.

I read in firs post that it don't have root access, install su is an option, but in option menu, in developer options it have root access, and it isn't necessary install any root manager app, but probably is recommended
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] daitalos:
very right

of course is not necessary , rom works normally without root...but if you want some "root app" (for example deathly adiutor etc) then it is necessary root access (as & the busybox)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] jax_xon:
I do not say the opposite, I only say that it is not necessary to install any application to have root access, as I said, in options of developer is the option of root access
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] daitalos:
sure

only for those who want to use "root apps" is necessary...yes in develper option , there is a choice / root access > adb or off ...rom working very well , no problem there... (especially in this kernel, team did awesome job)

Anyone else have a weird update to the latest official build? I flashed and walked away to find my tablet rebooted back in to recovery. Flashed again and it was fine but now I'm getting gapp issues and all my disabled apps are back.

Not a huge deal, I'm going to try a gapps reflash once I get it downloaded on my slow ass hotel WiFi.

Camera not active, crashes lineage system. All blocked.

Hi,

I use now the lineage nightly unofficial 20180811

The camera crashes. I have to restart the system.

Before this I used for several days

the unofficially nightly 20180108. There the camera did work.

Is this a bug on this version?

My comliments for the makers. It is very nice to see my sm-t520 n2awifi with Android 7.12. I am very happy with this los.

Grtz.

How does this compare to the Resurrection Remix ROM for T-520? Other than the lack of updates for RR I am satisfied as it is pretty stable with no major bugs, but I might switch if Lineage compares well.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] petty500:

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] hamudistan:
Yes, can confirm it's very solid rom. Only thing missing for both, offical and unoffical is a working twrp higher vs. 3.0.2.0
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] mwahahaa:
Thanks guys, but I was more specifically wondering how it compares to the Resurrection Remix ROM. Probably there is not much difference as they are the same android version. Also, I am using TWRP 3.1.1.0 on RR. Does that mean I have to downgrade TWRP to 3.0.2.0 in order to install the Lineage ROM?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] hamudistan:
It's a long time since I had RR the last time, so I can't tell. For the twrp: If 3.1.0 works for you keep it, you're the lucky one. It caused nasty errors like bootloops or sudden reboots to many of us. You don't need to downgrade. Only when you have issues with stability of rom, cause its twrp causing them.

Viber, Skype, HDMI Sound problems

Just started my Lineage experience on an SM-T520 with LOS 14.1-20180908-NIGHTLY-n2awifi.

Installation went rather smoothly following the stock Lineage installation instructions, except probably:

- Could not get Heimdall to work, resorted to Odin 3.13.1

- Could not back up pre-LOS system to SD card with TWRP 3.1.1, resorted to TWRP 2.8.7. Might be a problem of the SD card.

- Lock screen did not rotate. Fixed by modifying /system/build.prop.

After a few days of setting up things and apps I experience the following issues (none of which I had with the stock ROM):

- Sound does not get routed to TV through MHL/HDMI adapter.

- No audio with Viber. More precisely: If I call someone else, he can hear me talking, but I cannot hear him. If someone else calls me, everything works fine.

- No audio with Skype. Tried the Skype echo service, to no avail: Nothing gets echoed.

Seems that Viber and Skype do not recognize the tablet's speakers. In Viber, the speaker symbol is greyed out, and Skype displays a "speaker off" icon.

Any help appreciated.

Oh, and many thanks to LaCruz and all others keeping "old" hardware useful.

Update: When using headphones, sound works fine both for Viber and Skype.

Last night installed LOS 14.1

One clue about Heimdall: it worked with Samsung drivers but I've read and confirm that only the first command works per session, so don't test, just execute the flash recovery.

Anyone got Netflix working on HD? DRM info shows as L3.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] MrBungle67:
Netflix really is a bummer...looks like absolute crap, just bunch of pixels.

I was running the Liquid Death ROM for a long time, and didn't have this issue. Then had bunch of battery issues, along with performance problems, so I decided to move on and try the official signed LOS ROM.

Tablet was once more smooth like new, and battery seemed a lot more accurate.

Then tried to watch Ozark, and ended up downloading the 1080p torrent lol.

I since tried the unofficial LOS ROM, went back to Liquid Death, back to the official, none bring L1 DRM back, and netflix looks like crap on all.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] shakatu:
I've been using the official June 8, 2017 build for over a year now due to some of the issues that have been occurring on builds ever since. I keep thinking about updating, but then people report concerns so I haven't. The only bug that I run into is the mic records really quiet, and sometimes the camera crashes, but I never use either so it doesn't affect me. I can watch videos using any app just fine.

I backed it up here since you can't find it on their servers anymore.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] MrBungle67:
Nope...didn't change anything, Netflix is ugly. No problem in Youtube, 1080p looks good.

I really don't understand their philosophy here...in their attempt to prevent piracy, all they do is encourage it.

99% of people who root/install custom ROMs is to simply get as close to Android as possible. Heck our $600 tablet would still be on 4.4.4 if we were waiting on Samsung.

We don't do it to pirate Netflix, and no matter what they do their stuff is gonna be pirated anyways.

So here Netflix, I pay for a Netflix 4k account, and because of your stupid crap I will download your shows through illegal platforms just so that I can watch them in HD. Nice job!

I have downloaded several of the LOS v7.1 versions of Android, but keep going back to RR v5.5.6 (Android 5.5.1 - HERE). Everything just works, including NF. And I am rooted.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] WVUTampaAlum:
I've been usin 06082017 build for over a year. I've tried upgrading multiple times and the builds were no good. I don't believe there are any official builds anymore with any real changes even though they show up on the los site.

I've had 41 day uptime on the 0608 build and other very long ones as well but now schedule a weekly reboot through tasker.

My fix for netflix is to download the content if possible. The quality is higher but still not 1080p.

I have a bunch of setting changes I do after reboot in deathly adiutor and recommend you check it there is probably a setting for the mic. I change amp/volt input (faster charging) and io scheduler

yes, true, but if you want performance you need energy....2g of ram and exynos....for this smoothness battery is ok for me.

reading this and other thread, seems that peoples is looking for a ROM that allow using the tablet like a multimedia station, with Netflix HD and other stuff like Alexa, talk to grandma with Skype and RR 5.5.9 is great for this

Everyone I feel like this thread might be coming to an end.

Even though Lineage has continued to support the Samsung Tab Pro 10.1 for years(which I am super appreciate of) I feel like end is nigh.

Support has seemed to have drastically decreased and I would be super surprised if we got a Oreo or Pie update anytime soon.

Anyone know of any Oreo or Pie ROMs for Samsung Tab Pro would love to know.

Maybe it's time to say our goodbye to our tablets.

Hi, from where did you download the build?

The only source of builds I could find is

download.exynos5420.com/LineageOS-14.1/n2awifi/

I am not sure if this site can be trusted. Despite of those builds I do not see any activity on it.

Also I would be interested in what specific did yoi find better compared with latest official? I see many changes in sources but cannot judge the changes from it.

Thanks
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] CM-Tester:
I did not download the build. I had just asked for experience of some users, who did use unofficial and official.

The download link for unofficial you can find in the op.

Last official here:

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Duncan.Idaho:
Ha, the download link to unofficial build in OP is exactly that one I found by my own somewhere else and did not know if it is trustworthy. At least now I know that I found the correct one ;)

And of course I knew the official before and use its latest build.

I wonder why the size of latest official is 297 MB and all unofficials are 308+ MB. Are they built differently? Just compression? Different sources?

Let's see if I will give it a try this or next weekend. Unfortunately it does not seem that there are more people interested. I still like my Tab!
