For now: Installing or upgrading without problems for anyone til nightly 20170211.

Nightliy 20170214 to 20170219 splits user in having no problems or having problems by installing/upgrading.

So what is the difference between 20170211 and the following nightlys?

By the way - new issue in 20170211 rom: Can't access ext SD-card with embedet lineage filemanager. It says: U need higher permissions.

I am rootet with SuperSU. Can't find an option to get higher permissions in options of that filemanager.

With alternative filexplorer there are no problems to get access to ext SD-card.

:good: Thank you guys for the lot of work to make this rom possible :good:
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] s.t.a.r.s:
I flashed the 19/02 two times, at first twrp ask install supersu?! But after reboot it stucks at bootanimation for 20 min.

Second flash without SuperSU, the tab boots in 5-6 min :good:

Then I started in twrp and flashed gapps and SuperSU.

So far everything is OK :good:

My last ROM was cm12.1, I wiped everything before and after flash the cache's
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] wizel:
Flased 0219 without success.

Did a factory reset and installed. System boots to a screen with the LineageOS logo, but then stops there.

Will try with a previous version.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] Tommi123:
I had the same issue. Solution: In twrp you have to delete folder "android.secure" on your ext sd-card.

I am trying to download this ROM, but when I click Nightly build I get a "Not Found".

Any help?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] van_gogh:
Did you know that this "Search Thread" box is quite useful?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] moloko01:
Thanks a lot. For the 02/11 this solves my problem.

After factory-reset with TWRP and flashing 02/15, gapps and super su i can't access sd-card again. So I make a backup of sd-card and reformat as extern in tablet. With 02/15 nightly everything seems to be okay now. Except the known video issues, sometimes. Finaly dirty flash 02/19, reboot and flash super su makes my tablet uptodate.

MHL HDMI works with video-only on 20170204 build, the same as it has always been for me previously on Cyanogen mod 12 and 13 builds. Hope that anyone finds this information useful.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] amnesico1:
You're absolutely right. Thanks.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] cuki3r3k83bln:
Thx ?

But I can confirm that HDMI also worked on CM 12 WITH audio. The only thing you had to do is to change the output in the audiofx app and then it was done...
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] amnesico1:
I am having the same issue as wizel with version 0219. Tested a "random" nightly build (0211) and it worked.

I am going to search in forum how upgrades are made, to upgrade from 0211 to 0219 to see if bug with 0219 persists.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] moloko01:
Just dirty update with twrp. Do no whipes!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] airtower:
some things are ok to whipe
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] amnesico1:
I did this: Full wipe; Installed 0211; wiped cache/galvik; boot the tablet and make the basic config; reboot to twrp and installed 0219 and gapps micro; wiped cache/galvik; rebooted and it's working fine.

Tks guys.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] moloko01:
Now after playing around for some days with last nightly I found the folowing issues:

- Accountsettings shows only google, exchange and email.

- random videozoom in tv-Apps like zattoo

- performance- and audiostutters in some games

- heavy battery consumptions in cause of ?mobile data usage?

But overall performance is verry smooth ?. Verry good rom so far.

I also try to load version 20170219 on my t520 but it gets stucks on the LineageOS logo. Then I loaded 02/11. So far it's working pretty good. One thing I noticed is the external SD card request permission dialog thing, that was introduced with Marshmallow, is not working. Otherwise, seems to be working great. THANKS!

I tried this, but it's still not working. I deleted the .android_secure directory using TWRP. Then I try to add SD card write permissions using a couple of apps (mainly FX File Explorer) and it crashes each time.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] moloko01:
With same problems I had to save the data from sd-card and reformat sd-card in tablet as extern.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] phice:
Still didn't work for me. Strangely it's not just FX File explorer that's crashing. When I click on a pre-formatted SD in the Settings/Storage, it crashes there also. So I put the microSD in my PC and got rid of the partition. Then I put in back in the tablet and it ask if I want to format it. I format as portable storage. That works fine, but after it has a partition, I click on it and it crashes again. Same crashing still on FX explorer.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] moloko01:
TWRP Updating from 2/19 to 2/25 ends again in bootloop.

I know, its a hard work to make it possible. Thank you verry much.

But it's also not funny to install each nightly as a new rom. Please better test new nightlys before public them. Or tell the procedre how to update with new nightlys to get them working in post #1.

Same here, but i flashed SuperSu again, not the gapps.

So far everything works.

With 25/02 the cam works better , no crahs after closing cam app.

And open camera also :good:

I'm still on 11/2 and have no issues with YouTube.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] MrBungle67:
My personal workaround, having a YouTube Red account, is to press home when the zooming occurs. Video keeps playing in background, go to the notification bar, re-select the playing video, and it's back to normal.

That is the quickest most efficient way I found of correcting it when happening.

Just installed build 20170304

I have problems storing offline maps on sd card in google maps. It doesn't work.

Storing on internal sd card works fine.

File manager can access internal and external sd card without any problems. Problems occurred with 20170225 build.

MapFactor navigator has the same problem. External sd card is recognised with 0.0 GB free space even though there is more than 18 GB free space. Worked correctly with 20170219 build.

Anyone with similar issues?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] dcuk75:
I had a problem with a 64GB card formatted as exfat. I'd never manually formatted it and it had always worked like that out of the box, including stock 4.4 and early builds of LineageOS 14.1 from this thread - however, it stopped working on 20170225 build and started popping up a message about filesystem errors even though it mounted it and I could browse the files with Root Explorer. When I took the card out and checked it on a Linux PC it found nothing wrong with it at all. I copied all the data off, placed it back in the tablet and let it reformat the card as portable storage at which point it stopped complaining about it. I noticed when I put it back in the PC to restore the files that it had formatted it as FAT32/VFAT this time instead of exfat.

While the card was formatted as exfat I could not get LineageOS to reliably allow permissions to access the card. Since the reformat it is now working fine.

Now running 20170304 build and have personally found no problems. I have to caveat that with the fact that I don't use HDMI output and only occasionally watch youtube videos, but they've always worked perfectly for me. :good:
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] daitalos:
yes agree

there is a bug with sd card ( working correctly only in Internal storage ) > > two screenshots > SD = 0 mb (fake) (this problem only in sd & maps,generally my sd working correct)

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] dcuk75:
Actually with further investigation this isn't working correctly.

With the Storage permission assigned to the Maps app it shows the sdcard free capacity as 0 MB and refuses to download anything. With the Storage permission disabled the card shows the correct free capacity and will attempt to download offline maps, but never actually succeeds.

Since my SM-T520 has no longer warranty, i've decided to root the device and install this rom.

I've rooted it and installed TWRP Recovery with this thread:https://xdaforums.com/galaxy-tab-pro-12-10-8/general/qa-how-to-root-install-custom-recovery-t3087451

My question in: now all i have to do is do a full wipe and than flash this rom, or i should do something else first (install some custom kernel etc. )?

The device has stock 4.4.2 Kit Kat now and stock kernel (nothing has been done with the tablet for two years - only official Samsung updates).

Will i be able to go back to stock rom if i don't like this rom ? (i have the stock one from SamMobile).

This is my first rooted device so sorry if the questions are stupid :)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] cuki3r3k83bln:
Yes, for the new ROM I would prefer a full wipe (without sd card), then install latest ROM, opengapps and supersu.

If anything goes wrong or you are not happy with the rom then you can always go back to stock rom via odin or samsung kies/smart switch.

Last update installed with no problems. However I had 3 reboots with apps that use the camera. Every single one starts slowly and sometimes cannot start saying it cannot connect to the camera. Prisma cannot start at all. Anybody got the same issue? Is it a known problem? Thx guys.

Mar 11, I figured it out. It was an underclocking to 200Mhz the responsible for the camera crash. Set it back to 250Mhz and it is all good.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] dcuk75:
I hadn't tested this before, but just tried with standard camera app and all looks good, both cameras working OK.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] asfpf:
Yup, it works with standard camera app but still with them the app starts slowly, doesn't it? Please, if you have a chance, try Prisma and Afterfocus. They both crash here.

Ok, i've installed the rom but i have one issue.

I has some flash for android but i can't install it as i get an error "there was a problem with the package analysis"

Second one is when i connect the tab to my PC via USB cable. On the stock rom i could see the files, now my PC sees the tab as a mobile device but there's nothing in it. How can i fix that ?

Also: the icon "Downloads" is missing - ive seen it in this movie https://www.youtube.com/watch?v=mAg9Jd_dsO8 , but i don't have it.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] shikhanshu:
Yes, i did read the first post before asking the question. It says "This thread is for Unofficial LineageOS 14.1 builds for picassowifi/n2awifi (SM-T520)".

My confusion is are they the same device? Or does it simply mean the same rom can be used on both devices?

Everywhere sm-t520 is known as picassowifi (twrp, cm, Google). Why a different name on LOS ?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] petty500:

Well, I installed this ROM for the first time. I used the instructions you guys posted. Worked great with no issues!! This ROM is fast and awesome compared to KitKat original ROM which I had installed. I really appreciate all the effort in getting the ROM working on my tablet.

I noticed that I am having the zooming issues as well when I play videos from Lynda.com app. YouTube appears to be good.

I have a quick question. When a new build comes out how do I install it without having to reinstall all of my apps again. Do I just do it through TWRP as I did the original? Will I ave to install Gapps and SuperSU again as well? If so, will it remember all the apps and and settings that I have installed? Appreciate the response...
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] hamudistan:
You download the new zip and install with TWRP ,then install SuperSu again. No need to flash gapps again

Hi, just a short note for anybody interested -

I have just upgraded from an early February build to the latest one (20170311) without any wipes, I have even forgotten the usual Dalvik and cache wipe. Everythings works perfectly. The upgrade recipe is really simple:

1) Flash ROM in TWRP

2) Flash SuperSU in TWRP immediatly after for root access

3) Reboot, wait, and enjoy

That's about it!

Regards and thanks for the awesome ROM!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] simonvfr:
And if you use the persistent SU from lineageOS, there's no need to reinstall after each new zip. Works perfectly with these unofficial builds as well as the official ones.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] van_gogh:
I don't see official builds for our device yet. Where did you find it? Thank you in advance.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] simonvfr:
Sorry, I did not express myself clearly enough. The Lineage persistent SU works for all official builds that exist (and there is not YET one for the SM-T520 / n2awifi) as well as for unofficial builds such as the one this thread is about. Persistent SU seems like an obvious bonus to me - means that, like gapps, it's a one off flash that persists through subsequent nightly/weekly flashes.

Okay, so apparently this need to be a completely clean install for the OFFICIAL release. According to the change-log their were a whole slew of changes including fixing the auto scaling in video. Fingers crossed!!!

I assume I have to do the Gapps and SuperSU install as well?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Android Development] dcuk75:
Wiped cache, dalvik, data and system from TWRP then flashed official build and rebooted. Completed first-run wizard and rebooted into TWRP and installed pico opengapps then rebooted. Last time, once more into recovery and flash SuperSU.

Everything seems good so far, no video or WiFi issues.
