It's there.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Yogi555:
Short update: The S2 wifi blobs are a huge improvement. With S6 blobs I had reliable dropoffs at medium router-signal combined with heavy wifi-load (no dropoffs with full router signal). With the S2 blobs no single dropoff even at weak router-signal and heavy wifi-load for several hours now.

Again, to enable developer options, tap settings, about tablet, build number 7 times until it says developer options unlocked. Go back to settings, system, advanced, developer options, enable android debugging and rooted debugging.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Yogi555:
As I said earlier, the routed debugging option is missing in my developer-options (with installed Magisk). Everything else is looking identical to the attachement of post 6. But maybe we should not cover this thread with the different ways to adb root. The really important thing is that the proposed fix works really great! At least for me and hopefully for everybody else who is willing to try it
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
Thanks, @Yogi555! It's great to know that replacing the blobs works on one of the other S2 models! We could only test it on gts28wifi (T710).
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
@Yogi555, about the Rooted debugging option: my T710 doesn't show that option, either, and I think it's because I have Magisk installed (@retiredtab doesn't).

If the device is not rooted, "adb root" temporarily restarts the adbd daemon on the device as root (there's a timeout period after which it will remove root access again).

I'm guessing that if the device is rooted, that isn't necessary - because adbd is probably already running as root . The Rooted debugging option is therefore unnecessary, and isn't shown.

In either case, when you do "adb root" on the PC, there should be a prompt on the device asking you if you want to allow access. Did you see the prompt? If you don't explicitly allow it, root access won't be given.

Also, "adb root" works on Windows (for an account that's in the Administrators group) without needing to be Run As Administrator, but I think Linux requires the command to be run as root (eg, sudo adb root).
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Yogi555:
Update2: after the night the T810 with S2 blobs was immediately connected to wifi this morning. Great!

Regarding "adb root" with Magisk: I'm running it from Win10 PC. Independent if normal commandline or commandline as administrator - after "adb root" there is no output at all, but a sound like connecting or disconnecting a device. After "adb remount" next, an error is displayed:

Not running as root. Try "adb root" first.

remount failed

Maybe my adb is too old (version 1.0.40)

However "adb reboot recovery" works and "adb root" then in TWRP as well. So strange, but no problem :)
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
Did you check the device to see if it's prompting you to allow this access? The prompt times out fairly quickly, so you might not see it if you don't check straight away. It does give a notification sound.

View attachment 5367873
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Yogi555:
The prompting came yesterday at the very beginning of the activity and I allowed it (including the always checkbox). "adb device" shows the device id.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
I don't understand why you'd see anything different from what I see. I use a Windows PC, I have Magisk (version 23.0) installed on the T710, and have previously allowed adb root access "always".

What I see is this:

> adb version
Android Debug Bridge version 1.0.41
Version 31.0.2-7242960

> adb root
adbd is already running as root

> adb remount
remount succeeded

> adb root
gts28wifi:/ #

I think there could be something wrong with your Magisk configuration. What version is it?
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Yogi555:
Downloaded adb version 1.0.41. Now I get "ADB Root access is disabled by system setting - enable in Settings -> System -> Developer options"

Updated Magisk from 20.4 to 22.1. and App to 23.0 => No difference :-(

In Magisk App adb is not listed in Superuser-tab. Can I add it somehow?
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
I think I know what's going on now.

I've just uninstalled Magisk, and (after the enforced reboot) I can now see the "Rooted debugging" setting in Settings > System > Developer Options > Debugging.

Mine was ON, but had been hidden by Magisk's presence, as I suspected.

If you uninstall Magisk, I think you will find that your "Rooted debugging" is OFF. If so, turn it on, then try "adb root" etc. You don't need to root the device in order to use adb root functions. If you want the device to be rooted, by all means re-install Magisk - but with that setting still ON.

I'll be very interested to hear what happens. :)
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
The simplest way to check that adb root has actually given you root access is to "adb shell". The prompt will end in a "#" if the shell's running as root. As mentioned in an earlier post.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] CuckooPenguin:
Want to also quickly confirm in here that the S2 Blobs are working real fine for me as well.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
I've just re-installed Magisk and proved to myself that Magisk 23 is hiding the setting. I found that Magisk 22 didn't hide it - I re-installed using a version 22 zip that I had on hand, checked the "Rooted debugging" setting, which was still visible, then updated to Magisk 23 via the app. After the reboot, the setting had disappeared again.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
I did some testing today and found that (at least on my device) the wifi instability with S6 blobs might be because they're not coping with a dual-band network (2.4GHz and 5GHz bands in the same SSID).

I found S6 blobs choose the 5GHz band, don't switch to 2.4 GHz if the 5GHz signal quality is poor or missing, and don't always automatically reconnect to 5GHz when the signal improves. S2 blobs also prefer the 5GHz network, but don't drop out as quickly if its signal quality is poor, and can switch to 2.4GHz if the 5GHz signal is low or missing.

I also found that both S6 and S2 blobs are quite stable if the network is single-band, whether that is 2.4 or 5. Both of them reliably reconnect automatically on reboot to a single-band network, and stay connected.

Have other people who've had problems with unstable wifi also been using dual-band networks?
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Yogi555:
Confirmed! I did what you suggested - activated rooted debugging after Magisk deinstall, installed magisk again => adb root works now and the flag disappeared again in the developer settings.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] Yogi555:
I think you are right - i noticed the preference for 5GHz as well some time ago with S6 blobs. I had a 2.4 GHz only repeater very closeby, but the tablet decided to connect to the weak 5GHz signal and dropped continuousely ...
[Galaxy Tab S2 Q&A, Help & Troubleshooting] T_I:
I have to admit I had the wifi issue in the old image (0307), but in the last one (0718) it seems to be resolved.

Edit: Nop, still dropping here, dual AP dual band, single SSID.

Edit 2: the lineage-16 blobs for wifi seem to work, testing more.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
Hi, @T_I. We now know a little more about the dual-channel behaviour, namely, that the S6 blobs seem unable to use the highest 2.4GHz channels. The channels I tested were 11 and 13. It works with 11, but can't communicate with the access point on 13 (and might apply to 12 as well). So if your dual-channel network is using 13 for 2.4GHz, it would still seem flakey when the 5GHz signal is poor and the device can't switch to 2.4.

One difference from the previous roms, at least on my device, is that auto-connection at boot / wakeup and auto-transition between bands are working with this latest version. Neither function was working on a dual-band network with the earlier versions - even if the 5GHz signal was strong, it wouldn't reliably auto-connect.

I haven't yet checked whether the S2 blobs can handle channel 13. Perhaps you could test that?
[Galaxy Tab S2 Q&A, Help & Troubleshooting] PaulK.:
Magisk ist the reason. But there is no need to uninstall Magisk. You probably have 'Magisk Hide' enabled. Disable this in the Magisk setting and reboot the tablet. Now the 'Rooted debugging' option should be available in Developer options. You can enable Magisk hide again after you are done.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
You're right @PaulK.

An important point I missed is reboot after turning off Magisk Hide. Magisk Hide was the first thing I thought of when I noticed that the option was missing. But I don't think I rebooted after turning it off. I would not have thought it necessary, because Magisk doesn't ask for or advise a reboot to make the setting take effect, and the SafetyNet test passes immediately after enabling Magisk Hide.

It seems the setting does hide "Rooted debugging", but that doesn't take effect until reboot. When Magisk Hide is turned off, the effect isn't reversed until reboot.

I have seen "Rooted debugging" disappear without Magisk Hide, though. With Magisk v23 installed as an update from v22 via the app (and after all the mandated reboots), the option had disappeared. No Magisk Hide or any Magisk modules installed. [It had stayed visible with v22.] And this is not consistent. Some rom flashes and numerous boots later, Rooted debugging is visible with Magisk v23 installed.

So I'd say the advice should be: disable Magisk Hide and reboot. If that doesn't work, uninstall Magisk.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] lpedia:
Now I have tested the S2 blobs and found they don't handle channel 13, either.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] PaulK.:
It has been only 1 day with the new/correct drivers, but I am already really delighted. Our apartment is a Wifi killer any day. Overall reception strength seems to have improved and - more important - I have had no a single Wifi disconnect. I had regular Wifi losses before, especially when wandering around switching between APs.

What can I say? Great! Thanks a lot for this fix.

That's the same version everyone is using when they replace the S6 blobs with S2 and so far no problems connecting with S2.

Please describe your wifi setup. Is it single or dual band? WPA2 or WPA3 or a combination? Is your router running stock, dd-wrt or openwrt?

WPA2 dual band, stock. Wifi toggle says Turning on... then it changes back to off after a few seconds.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] retiredtab:
I wrote the initial instructions using a linux OS. Then I had lpedia who uses Windows check and verify them. He modified them slightly so it could run on both platforms and I tested his changes and it works. Both lpedia and I have t710 and both us of use the July 18 build and we never had wifi turning on and then off. Once it's on, it's on.

In addition, 2 others have used the same instructions for the t810 and verified they work and the S2 blobs work better. You can see Paul K say it works with T715.

I checked your posting history. Here

https://xdaforums.com/t/rom-unoffic...t810-t815-t815y.3879302/page-94#post-85085951

it seems you were running 16.0. If you just switched from 16.0 to 17.1 for this wifi test, do you wipe and format data? If not, a "dirty flash" might be causing you problems. Anytime you move between major versions like 16.0 to 17.1, it's recommended and in some cases mandatory to wipe everything (system, cache, dalvik, data) and format data.

If you have all your data backed up, I suggest the following

1. boot into TWRP and wipe system, cache, dalvik, data. Then format data.

2. Reflash July 18 build. Do not load gapps, magisk or anything else. Just July 18.

3. boot into OS.

4. only setup wifi and see if it works.

5. if wifi works, then do the S2 blob replacement using Windows since that seem to work for you.

6. reboot OS.

7. see if wifi works.

PS. Through testing by lpedia, he found out that channel 13 doesn't work in 5Ghz with either S2 or S6 wifi blobs.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] zed011:
I tried, still does the same thing. I have 2 T710, same behavior on both wifi just turns off shortly afterwards. No dirty flashing, wiped then flashed july 18 build with no gapps. Should I try linux, would that really make any difference?

@ananjaser1211 , in my github commit message at

https://github.com/universal5433/pr...mmit/3984c2ef6852794a939b8eda689fc477705d5c86

I made a typo. I wrote "lpedia discovered that channel 13 at 5Ghz doesn't work with either S2 or S6 wifi blobs in 17.1."

It should have said at 2.4Ghz instead of 5Ghz. That's my mistake NOT lpedia.

So the correct wording is

lpedia discovered that channel 13 at 2.4Ghz doesn't work with either S2 or S6 wifi blobs in 17.1.

So... you just sit in front of that massive screen? Can you even see the whole thing at once?

Haha, yes. Both monitors are on full articulation mounts (up/down, left/right, back and forward, tilt). They can stick out 2.5 feet or sit flush to the wall so I can move them around. I usually have the monitor further back than in the pic but I wanted to get as close a grouping as possible when I took the picture.

If the 43" is as close as it is in the picture then that is too big but when I put it back about 9 inches its perfect for me. My eyes are not that good so if I dont have my glasses with me I can still see :)

Now I do not like so much RGB, I would prefer to see what theme is your personal preference, but well that is a matter of personal taste.

The monitors are too big at for this sitting distance, I think you would have a nicer experience with 3 smaller monitors (not small just smaller), or doing a setup in which your monitor is set farther away, maybe with a couch in from of it, but still visible from your working desk, this would require a whole setup modification and changing the placement of your desk tho (I have seen this kind of setups).

All in all, neat as I said before, but think about the 3 monitor smaller monitors setup, I think that setup would make your work or gaming more pleasant.
