I don't have difficulties downloading from file-upload.net. I'm running Firefox on Ubuntu. Yes, it is not directly a download-link, only a page with a JavaScript-generated download button. But I prefer file-upload.net over AndroidFileHost.com, since AndroidFileHost is *very* unresponsive and upload doesn't work most of the time. file-upload.net's upload is simply working.

Nice try file-upload.net, but I’ve got a 5 year old iPhone, not a 2 year old Android
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] menner-xda:
You are right - the /e/OS chromite browser also isn't able to download from file-upload.net and also not from androidfilehost.com. There are some aggressive ad popups, like your "clear storage".

But using Firefox Klar on /e/OS, or Ubuntu with Firefox (with uBlock Origin) or Epiphany or Chromium, the download is working and working fast.

Don't you have got a desktop computer to download those images?

I'll look if I find some other eligible file sharing solutions. Some have a 100 MB limit, some have a 2GB overall limit, some are deleting files after a week, some are usable only with a paid account, or the downloader will need an account as well.

I uploaded /e/OS-1.17-q ROMs for v2awifi, v1awifi, n2awifi, n1awifi also to MediaFire. This site is usable with the /e/OS browser, hopefully also with the iPhone browser.

Im lost with all links and dont know which is the lastest link for SM T-520 tablet.

Can someone tell me the working links and if it works well or have bugs?

I apreciate if someone know where i can find the stock rom in case of brick.

Regards!

Several ways to get it:

Either from websites like samfw, samfrew, sammobile or use SamFirm_Reborn on a Windows PC to get it directly from Samsungs servers (faster download and safer source).
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] capitansolo:
Thanks but all i found from that sites are links off or links to pay :(
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] bmwdroid:
Then you didn't try SamFirm_Reborn.

On Samfrew btw I've just tested to download (slow of course) and they allowed me to without any costs.

Ok, would take 4h to download, but I wouldn't care.

Tested for my T825 as I don't have T520.

To lazy to test the others.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] capitansolo:
Thanks! Finally downloaded stock rom from SAMFW.COM.

Now its time for installing new rom but i found a problem... OEM installation dont appear on developer options ¿?¿?¿?¿
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] bmwdroid:
Imho that's no problem at all as these old devices miss that option.

The only lock in those days were provider locks (ATT, Verzion aso).
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] hamudistan:
wired mtp file transfer does not work, device is not recognized by linux, other devices work. Used sftp as workaround.

But anyway a great buld for t520.

Never thought to get something like this.

Many thanks

Hi,

Having seen kb8no and others install this rom with success, I just installed it, its looking good.

Did have the 'Hello Google' to Pin screen loop, but thanks to Larision post and tip

I managed to find set of headphones with mic and got past that loop.

Did flash straight from LOS 14 to LOS 17 , so not from a Samsung build, so not sure if that was the cause of the loop.

Will post any issues I experience.

Thanks for ROM.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
Hi!

After all the positive experiences, I also installed this ROM on my SM-T900.

Unfortunately, my experience is less positive.

The tablet randomly crashes and reboots when I use any browser, particularly Firefox.

Also, when the tablet is on, it charges very slowly, to the point where it actually drains the battery when I'm using it with the charger plugged in.

When I'm not using any apps or on the home screen, the tablet works properly though.

I upgraded from 14.1, although I did a full wipe in between, but not internal storage. I also upgraded to the latest TWRP before flashing. I flashed the ROM + Gapps nano.

Also, USB connectivity is broken, so getting old ROM files back on the tablet is kind of a pain, since I want to revert back to 14.1 now. Should have backed up in hindsight T.T .

Still, I want to thank you for your work on keeping this tablet alive. If the ROM becomes more mature and stable, I will for sure come back and try again!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
By the way, the voice assistant loop only happened for me when I set the language to US English.

When I set it to Dutch (my native language), the loop does not occur at all!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
I tried reverting the device completely to stock, and then following the installation instructions again, and this time, no crashes!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] kb8no:
Ah ha! I was thinking about this and planning to try it. And after you flashed back to stock and then flashed LOS 17.1 again did it fix other things? Did the PIN unlock on first boot start working? Can you install purchased apps directly from Google Play app? Did the lagginess improve? Did the Google Assistant issue on first Google login disappear?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] TechDriver:
Lagginess won't improve, its probably fault in kernel and the same lagginess is in lineageos-14.1 deathly edition so it's up to devs to fix it however theese tablets aren't really developed further, so I don't expect this to be fixed. Also installing purchased apps will be able from browser version of google play store because of missing google play protect certification.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] TechDriver:
I am currently working on building lineageos-15.1 and 16.0. I see theese versions as more stable because of more developed code. I had successfully built los 16.0 multiple times but always run into bootloop. Los 15.1 is even more tricky. I run into multiple problems building it but if I will succesfully complete it and it will be stable enough I will give you link to download.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] kb8no:
Is "missing Google Play Protect Certification" a dev fix or is it a build fix that you might be able to handle? Same question about SELinux compliant?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] TechDriver:
To make selinux enforcing, devs have to write device specific selinux policies. It's set to permissive because these policies are missing. To get device certified device must pass safetynet chceck. This is also related to device code but magisk safetynet fix module might do the trick. If safetynet check is successfull, it's necessary to sign rom with google service framework id here: https://www.google.com/android/uncertified/?pli=1 Haven't tested it myself yet but it should be right direction.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Larision:
Happened to me with language set in ES Spain
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
Another trick: Simply do not set up wifi and your Google account on first-time setup.

Then, when you arrive on the home screen, you can connect to wifi and set up your account.

Once the loop happens, you can now simply go back to the home screen because the setup can no longer prevent you from doing that.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
Can't comment on the PIN problem because I used the workaround I explained in my previous post. I can install purchased apps completely fine. SafetyNet also passes after flashing Magisk and enabling MagiskHide. No safetynet fix module flash needed.

General lagginess is still there sometimes, but I just blame the crappy Exynos SoC for that. It's not a very powerful chip. As TechDriver mentioned, it is about the same as on LOS 14.1.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] kb8no:
@xIntenso Thanks for these posts. Indeed, not logging into WiFi allows you to boot into LOS17 without the headset being plugged in. Then log into WiFi and "Finish Setup" and log into Google. I got no boot loop and was able to click through Assistant screens . I then installed Magisk and MagiskHide and passed SafteyNet. This is progress.

However, PIN screen on first login after boot still fails intermittently. PlayStore still does not recognized purchased apps. I want to get there. What am I doing wrong / different that you. You flashed back to stock, do you think that might have been the difference?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] kb8no:
@xIntenso I tried to go back to stock. I flashed my last OTA LMY47X.T900UEUBOJ1 using latest Odin3_v3.13.1. Got a PASS but it boot looped between startup screen and Samsung screen and I could never get it to load. (PANIC). But the stock was flashed and present, just wouldn't boot. It would be interesting if someone can make it complete the boot.

Apparently the bootloader is unlocked. After flashing a stock that can't complete a boot, I was able to Odin flash twrp-3.5.1_9-0. However, you need to uncheck auto reboot and manually use Power - Up Vol to boot directly in to the new recovery without the booting the ROM so a to get twrp to stick, otherwise stock ROM will overwrite with stock recovery. So I was able to twrp flash 17.1 and Gapps with zero problems. I cannot prove that flashing stock helped anything but I think it did.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] kb8no:
There is the noted problem with the lock screen. The PIN entry fails at the first lock screen after boot. The tablet then becomes unresponsive and the lock screen times out. Usually the second try works but sometimes it may take several attempts. I have discovered on my tablet that if you allow the first lock screen to time out without touching (only takes 15 or 20 seconds), and give it a couple extra seconds of black screen, then the following attempt works every time.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xfiver:
Hi,

Been using this ROM some 5 days, I use it mainly for reading news/tech websites and playing games like Freecell etc. So a quick report as I see bugs are now being collected

The ROM is relatively fast but I get the occasional lag/audio stutter but not too bad.

Main issues:

1) Regular crashes to Home Screen when using Chrome or Samsung Internet ( specially where the website have large content and adverts e.g. wccftech.com),

I have also had 2 crashes to reboot again when in Chrome.

2) My wallpaper (2560x1600 pixels ) always takes about a second to load, so when I switch to home screen the background is black then a second later wallpaper appears.

Plusses:

1) One game that used to crash almost everytime a video type advert was played in LOS14 now crashes slightly less often.

2) Battery life seems slightly improved (at least for me).

Thanks
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] kb8no:
@xfiver Thanks for your post. I too have periods of brilliance with this ROM working great. I am having a freeze - crash - reboot issue as well. Trying to isolate it. I have suspects. Lock screen is where I have had issues and it will freeze-crash-reboot right after screen time out and I can never get back to the lock screen. At least once it started shortly after I applied a wallpaper so I am suspect that this contributes.

I suspect the freeze and time out of first lock screen after boot is related. If you have the inclination, do a clean flash. Then always let the first lock screen time out before entering the ROM. Then do not touch the wall paper. See if that helps. I am thinking so.

I am also suspecting the mouse so I un-paired it and now finger only. If you are using a mouse, shelf it for awhile. I suspect Magisk so I am refraining from that as a trial. I am suspecting an app called Menu Button which puts buttons on the screen but also is the best thing yet for preventing portrait view when you want everything landscape and I am refraining from that too.

I am suspecting Nova and abandoned version 7 beta and went back to Google Play version. I am trialing this now.

It is premature but I think it is doing much better now. I think it is a graphics problem of some sort perhaps in the kernel but apparently not likely that any dev's will work on this.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
For me, I needed to do a reset using the recovery that comes with the stock ROM. After that, first boot will take LONG, so don't panic if it doesn't boot quickly.

IDK how long exactly, because I flashed with Odin, rebooted into recovery, reset, and then went to cook dinner. When I came back half an hour later, I was greeted with the stock setup screen.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
I can't help you with this one, since I do not use any PIN at all.

Lock screen can indeed take a second to load my wallpaper, but the desktop always has it loaded. I'm using the Microsoft Launcher by the way.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xIntenso:
Most of my problems also occur when visiting large websites, using Firefox in my case.

The flash from stock did change that from crash and reboot to temporary freezes, but I don't use my tablet all that much, so it might have been luck. I'll report back if my Tab ever reboots on me again.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xfiver:
@kb8no

Thanks but sorry I cannot comment on your usage, my requirements are really really basic.

I just want to surf using Chrome, I can live with crashing games.

If Chrome (or Samsung Internet) did not crash so often I would be happy with this ROM.

If xIntenso is having almost the same problem but with FireFox, it may be a graphics related problem. Usually the crashes are when the site is still loading and I am doing finger swipes - it never crashes while I am just reading.

My wallpaper is a jpg of something like the Hubble deep space photo, so it is not the stock.

After day 3 I did reinstall the ROM just in case I made a mistake ( wipes etc) but the tablet performed just as before.

One question I am not clear is, ( re your suggestion)....

Are people who started from a stock ROM having a better experience?

(Odin needs a stock ROM and I lost my stock backup some years ago)
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xfiver:
Just eating some humble pie.....

My wallpaper lags are probably self-inflicted. I switched to a stock wallpaper and lag disappeared ( except on powering up from sleep).

I could not find the location of stock wallpapers, but my own wall paper was 3.59 Megabytes. I have the impression that the stock wallpapers are 10's of kilobytes.

Maybe the lag was the load time??
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] kb8no:
@xfiver I use the stock wallpaper that is the default on boot and do not touch it. I also disabled the lock screen to "none" as suggested which was helpful. I also changed rotate screen from the default none to the usual 3 check boxes and this seems to help the occasional portrait screen app that can't adapt to landscape. I just use my finger and disabled the mouse. With this it works better. Much rarer crashes and cold reboots from graphics. Then there still is the problem that still exists with erratic scrolling in browser type apps (Google News, Chrome, XDA) where the longer your scroll the worse it gets. Then the app force closes. I have done everything I can think of and this ROM is not up to usable needs for a daily driver. It was fun to see that it actually worked. I guess they tried really hard to get us here and doubt there will be further development.

I have abandoned this and gone back to 12.1 which works great. It does have a few mouse glitches with interpreting clicks but nothing bad happens and you can move over to the finger occasionally when you don't get what you expect. Graphics is solid and you can use whatever wallpaper you want and scrolling is smooth. 7.1 also gives you "expanded desktop" which is great when I use Citrix and gets rid of the bars which were abandoned by LOS in later ROM's. Thanks for trying with me.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Kooneybert:
I tested this ROM for about 3 days now. Before installation, i wiped complete internal storage and i didn't install google play stuff and did not root the device. So my experience is with a perfectly clean installation. This is what happens:

Pro:

+ pretty fast

+ camera working fine (this was a problem on my previous ROM)

Con:

- random crashes (to homescreen) in several apps

- video playback is stuttering in any app and any resolution

=> The Cons are too big for me to use this in everyday. If they were fixed, this would be a great ROM

Edit:

I just tried to switch back to Lineage 14.1 (https://xdaforums.com/t/rom-7-1-x-sm-t520-unofficial-lineage-14-1-n2awifi.3538770/) but came across unexpected issues.

1) On first boot, Lineage 14.1 crashed (several apps were reported to crash, after selecting the language, android crashed aswel) and wasn't able to boot up again.

2) I reinstalled with an older TWRP version with the same result.

3) Flashed stock rom with odin (without a problem), flashed TWRP with odin, tried to install Lineage 14.1 but now, TWRP crashes as soon I tried to flash the rom zip. Repairing the file system didn't help.

4) Now I tried this Lineage 17.1 rom again and it works.

The strange thing: Lineage 14.1 worked before and I didn't see anyone commenting any problems like me. Is there any chance, Lineage 17.1 changed something that prevents me from rolling back to 14.1?
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xfiver:
@kb8no

Its a shame that you need to go back ( to I assume LOS14) , this ROM was not bad for a first issue. I do hope some developer issues further updates.

I am minimising the browser crashes by letting webpages load as much as possible before (finger) scrolling/swipes.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] c8m3r4n:
Installed fine on my sm-t520 .First I backup all partitions, then I wipe everything installed lineageOS 17.1 I didn't install opengapps felt it might be too heavy so I chose to installed instead Aurora apk from which I got my applications. Set up went well no problems playing videos through VLC player ,browser opening is smooth no problems or crashes ,battery life is better than the latest lineage OS 14.1 -Vanilla -20210413 .Good experience so far still testing.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] TechDriver:
Make sure to wipe cache and system and format data before installing rom.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] TechDriver:
I advice you all to limit background processes to minimum because RAM capacity is real limiting factor on these tablets that cause lag.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Kooneybert:
Okay, my post wasn't that clear. I wiped everything INCLUDING cache, system and data.

Btw, in the meantime, I reinstalled this rom again using the exact same path as before. Now, videos aren't stuttering no more. But instead, there is a 60% chance that the picture is zoomed to the top left quarter of the image...

Also, I now (succesfully) rolled back to Cyanogenmod 12.1 (Android 5.1.1). Yes, this is old ****, but for me, this seems to be the best option because it's just running faster since Android doesn't eat all of the available RAM. This Lineage 17.1 seemed to be very ram-hungry, btw. No wonder many apps suddenly close - they are lacking RAM. If anyone else is thinking about this RAM problem: if you don't install the gapps and just download the apk files from others sources, your device will have about 200-300mb more usable RAM. But this won't be enough for this Lineage 17.1 build in the current state, unfortunately.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] wilkerjnc:
I installed this over Lineage 14.1, full wipe first; and it will not go past the boot screen.

Where can one get the "latest official Samsung Firmware"? I have tried a couple of spots, but they all say 'invalid' or such when attempting to flash.

Tried to reflash back to 14.1 but now that seems to be hanging.

Using the latest TWRP as well.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xfiver:
@TechDriver,

Just so I have not missed something, please explain what you mean above....

Does it mean, to close any app not being used rather than allow to sleep? or is there more I can do to save RAM ... e.g. other background processes that are not so obvious?

Lack of RAM capacity makes sense, as crashes seem most frequent on websites with heavy content... but please explain anyway?

Thanks
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Kooneybert:
If you take a look at developer settings (enable by pressing "build number" several times), you can find the option "limit background processes" (or kinda). There you can select, how many background processes may be active until Android will close the first ones (automatically).

But anyways, even with any app or background process open, these 2gb of RAM will feel like 256mb with Android 10.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] Kooneybert:
I used this one, I think:

Account Suspended

Keep in mind that you have to flash this via Odin, not via TWRP! Afterwards, you have to flash TWRP via Odin, again.

I have the T900 12.2 Tab Pro, I try to get a firmware from that site and keep ending up on a page: "Sorry, you can't view or download this file at this time." Is there another valid repository somewhere?

Thanks - found the option! The back ground processes limit was set to 'standard' (i.e. 20) have now set it to 4. Let me see how it goes. Thanks again.

oops - replied to my question, meant to be in response to KooneyBert tip above.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] c8m3r4n:
Hi all ,many are having problems with the new build lineage 17.1.My solution was Aurora store instead of play store through gapps, however if you need gapps then flash the pico version of gapps and limit the background processes to 4. This works well.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] TechDriver:
In developer options there is switch called limit background process just select limit all or least number of processes. It will save some ram for foreground apps, but every time you switch apps they will need to reload.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] mrduab:
I would just like to say I have installed this ROM on my SM-T900 and it runs surprisingly well! Everything is smoother and quicker and experiencing no crashes.

All I use it for is Kodi, web browsing and streaming videos.

One issue I do have is when watching video every now and then the audio freezes and buzzes for about half a second and then resumes.

I installed the latest TWRP and had to wipe all data as upgrading from a previous LOS caused it not to boot.

Is anyone else experiencing the audio blips? I've tried limiting background processes but it has no effect. If anyone could find a solution for this it would be great as we didn't have this issue on the previous LOS version.

Keep up the good work!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Original Android De] xfiver:
Thanks,

Both you and Kooneybert have suggested the same.. I have set background to 4 processes, (for last 2 days) but still experiencing random browser (Chrome) crashes.

I must say the tablet does feel a lot 'zippier', but occasional stutter, so sorry no new news.
