I think I found the problem regarding the wi-fi issues. The main router was set to channel 1 and I set it to channel 11. It seems to do better now and I have less disconnects. The bridged router was set to channel 13 and it indicated there is no internet. I don't know how to change that but I'll just use the main router for now. I still get disconnects during tablet sleep but I'm happy I got internet now at all!
[Transformer TF300T Android Development] pe1dnn:
I have no idea whatś going on but for me getting the info yields nothing. So I listed all files under /sys/kernel and sure, no target_info directory! This was first when running #14 as is and since the directory did not show up I flashed kernel 't1' but got the same. The output is when running the t1 kernel. Output:

root@tf300t:/ # cat /sys/kernel/target_info/info

I now ran this with adb shell but using the terminal on the tablet gives the same result.
[Transformer TF300T Android Development] timduru:
Ok, so must have been overlapping channels.

For channel 13 did you change the regulatory domain in wifi => advanced to "EMEA..." ?
[Transformer TF300T Android Development] timduru:
It's only for those who have flickering issue and were testing the test kernels.
[Transformer TF300T Android Development] pe1dnn:
That's why I flashed the t1 test kernel. Unless you added it only to later test kernels. I have this flickering so I was curious if I had the same cpu.
[Transformer TF300T Android Development] Reksho:
Yup, already did that. Doesn't seem to help sadly.
[Transformer TF300T Android Development] timduru:
yes, it was added in -t3

But it is in -t8 too

so flash that one directly :P
[Transformer TF300T Android Development] pe1dnn:
Indeed confirmed, using -t8 kernel: cpu_process:2
[Transformer TF300T Android Development] timduru:
and what about flickering with -t8 ? please tell me it's gone ;)
[Transformer TF300T Android Development] pe1dnn:
I just scrolled a bit in Chrome and did not see anything disturbing, but it was sporadic for me so to soon to draw conclusions after only a few minutes of use :). So far so good.
[Transformer TF300T Android Development] desireleß:
unfortunately -t8 did not fix it. I followed my cpu freq steps as before. Until I set min freq to 470 ,it's flickering
[Transformer TF300T Android Development] walttheboss:
You can also try disabling captive portal login. This will prevent the tablet from disconnecting when it decides there is no internet behind the router. Do from terminal.

1: su

2: settings put global captive_portal_detection_enabled 0

Reboot!
[Transformer TF300T Android Development] Reksho:
Thanks for the suggestion but it doesn't work unfortunately. Probably the quality of the internet is not the reason the tablet disconnects itself.

[MENTION=3951330]timduru[/MENTION]

Flashed the new kernel, screen flickering still remains.
[Transformer TF300T Android Development] Ctrl-Alt-Del:
I was back using gpu-t1, with interactive governor min 475mhz and max 1500 mhz freq.

Revert to default freq interactive 204-1500mhz and reboot.

Flash gpu-t8 and shutdown.

Reboot rom.

Results ;

It's almost gone, flickering appear rarely for me. Still there but gpu-t8 is the best patch kernel so far for me. No clear pattern of what's triggering the problem. When loading webpage or using SwiftKey keyboard can make my screen flicker. Thank you!
[Transformer TF300T Android Development] Berend de Boer:
I also see tearing/flickering, tip to set min freq to 475 works for me too.
[Transformer TF300T Android Development] Beonico:
I used the "Device Control" app to disable the GPU/Open GL "Smart 3D scaling".

The flickering disapeared with the standard 204/1500 frequency settings.

Give it a try
[Transformer TF300T Android Development] Nicolas Love:

Clarification

Hi, Tim.

I'm sorry about "Wi-Fi Investigation" post. It is really confusing. I thought it's just possible to compare kernels, but it turned out to be more difficult thing. So, let's leave this all behind. Let's move on. Moreover, now we must solve flickering issue, which is more important.

Peace.

I forgot to mention it's flickering on the (Asus) splash screen, too. Probably it's not important, I'm quite a noob... :cyclops:

I tried turning on all of the permissions for ES File Explorer that I could find, and it still wouldn't recognize the MicroSD card that I had in the Tablet Slot. Does Marshmallow have a different structure for the mount points? Maybe it just didn't recognize the location.

Sorry, but I don't have time to go back to Marshmallow to check right now. Besides, I've started to get used to the very handy Katkiss-style Multiwindow function. :D

Thans for this new ROM.

Just report a problem with auto rotation, it doesn't work on "006".
[Transformer TF300T Android Development] pastorbob62:
Well, dang! I successfully flashed the ROM (6.0) and I followed the procedure completely (Full wipe, format data, flash ROM, SuperSU, Gaps, Wipe Cache, Dalvik). Rather than trying to restore my apps and data with TitaniumBU I went with fresh downloads on everything. However, after the initial setup, I couldn't get anything to download from Play Store. I would click on the app, select "Install" and all it would do is attempt to begin the download (progress bar flashing). But it never actually began. I tried about a dozen different apps with the same result. So I am back on Lollipop #30. Fortunately I made a good Nandriod backup,

Any suggestions?
[Transformer TF300T Android Development] moosehead11:
Having the same problem with my 32GB MicroSD...nothing recognizes it except going into settings and apps. ES File Explorer, MX Player nothing seems to find it
[Transformer TF300T Android Development] joff1234:
Check md5 of gapps (bad download ...?) and flash it again
[Transformer TF300T Android Development] pastorbob62:
:confused: Hmmmm, not sure if you understood. All of the apps that were installed via gapps work just fine. The ROM worked fine. The problem was when I tried to download my own previously installed apps and install them. Play Store works, the apps just won't download. Not likely the md5 on the gapps file would be the problem.

So Tim, do you have any thoughts on this problem?
[Transformer TF300T Android Development] msrowley:
Hello to everyone, and thank you very much timduru for this great rom!! I have only one problem which I had since KatKiss 5.1 . My wifi turns itself off when my screen turns off, if not immediately then after a while. This causes all downloads to stop and/or google play updates and installs. I checked for wifi sleep policy and it is set to keep always on. I also come from a clean install with wiped data and system partitions, caches too. Does anyone has similar problems??
[Transformer TF300T Android Development] kangtastic:
hi all,

i can't seem to install this properly. from twrp i get the following error:

mount: failed to mount /dev/block/mmcblk0p1 at /system: device or resource busy

symlink: some symlinks failed

e:Error executing updater binary in zip /external_sdcard/...

tried installing from internal card as well

any ideas?

data is f2fs, everything else ext4 - formatted all partitions.

UPDATE: ran repair on system and that seemed to fix it this time.
[Transformer TF300T Android Development] msrowley:
I had the same problem! I solved it by installing the Kang twrp from the link in op
[Transformer TF300T Android Development] xxxericxxx:
For anyone else who has this problem, follow Tim's advice, after I seen that come up, I remember seeing Tim say make sure /system isn't mounted, so I unmounted it and it ran through fine. Also, since I am posting, This rom is absolutely amazing. Tim is absolutely amazing. I think he should change his name to Tablet Jesus, as he keeps resurrecting old tablets. Only bug I've ran into is the autorotate not going back from portrait, it does go back sometimes, don't know what was different from when it doesn't, but I quick reboot is easy enough to fix as I don't have too many apps that use portrait mode.
[Transformer TF300T Android Development] pastorbob62:
Nope! doesn't work. none of the apps (ES File Explorer, Titanium BU etc) see the external sdcard. Going back to lolliop#30 since i need to access my external storage from inside my apps.
[Transformer TF300T Android Development] timduru:
As said before for ESExplorer :

For the rotation issue staying in portrait mode after an app have forced it that way,

I was able to reproduce it on V006, but not anymore on the upcoming V007, so not sure.

We'll see once I release V007, if those who had the issue still have it.

In the meantime instead of rebooting you should be able to use an app like Rotation Control from the play store to force the rotation back to landscape if that happens.
[Transformer TF300T Android Development] compact_wisdom:
I'll give it a try on the weekend :)
[Transformer TF300T Android Development] BrateloSlava:
When you see this error during installation, simply restart the tablet and re-enter to the recovery mode. And start installation again.
[Transformer TF300T Android Development] vfrvulcan:
Only 5% drain overnight this time - something let go of a wakelock. Outlook did get uninstalled so possibly that was it for me.
[Transformer TF300T Android Development] pe1dnn:
Or save the time, go to the mount menu and unmount 'system'.
[Transformer TF300T Android Development] pastorbob62:
Wow! Talk about feeling like a noob! :o

Sorry Tim, but believe it or not I looked for an answer to this issue for quite a while last night b4 giving up and going back to Lollipop #30. I guess my eyesight is also going in my old age along with other things. I'll go back to the new ROM tonight after work and give it another whirl because the sdcard issue was the only problem I had with it.
[Transformer TF300T Android Development] Nicolas Love:
Tim, thank you for KatKiss Android 6.0 Marshmallow.

You are amazing as always!

I have a poetry.

You should follow Tim's advice.

And you will be living nice.
[Transformer TF300T Android Development] DriftJos:
Hi Tim, just installed the ROM and it looks great! Thanks man!

Only issue I have until now is the Home-button not working.

[Transformer TF300T Android Development] Reksho:
So I noticed that the overclock actually doesn't work on my tablet. As you can see in the attached pictures, the values are set on 51 MHz min. and 1500 MHz. But when I run No-frills CPU control (and multiple other CPU apps), they detect nothing above 1300 MHz (and below 204 MHz for that matter). Do the apps just misdetect it or is something wrong here with the tablet?

I have flickering issue too.

It started since #13.

Interestingly, it also affects Asus logo screen! I mean the screen after turning tablet on and before boot animation. Don't understand how it's possible!

Flickering

*headache*

There's basically 3 different types of issue with the new frequency table.

I think / hope / pray that I've cornered all of them now ;P

try these new test kernels :P

Yeah you're cpu_process:2 like the others who have flickering ;)

Buy a new tablet ! ;P

Or try these kernels ;)
[Transformer TF300T Android Development] pe1dnn:
Calling upon divine intervention now?

Well I have of those and unlike others never had a problem at 1,7 GHz speed so you may reconsider swapping it for another. I think I will try your new kernels instead.

Running -t10 now, no problems so far but I did not have this problem very frequently. I have not found a method to quickly check. What do others do? Anyway I hope with you your pray was answered.

[Transformer TF300T Android Development] DoughMucker:
Hi Tim,

I was experiencing quite a bit of flicker with KatshMallow v14. With t10 kernel flashed I still see it, but rarely and just for a moment. Only been testing for an hour or two. Will try t11 next.

[Transformer TF300T Android Development] DoughMucker:
Just following up on how the other two kernels perform for me:

t11 was similar to t10 (a bit of flickering). t12 seems to be the best for me. I haven't seen any flickering after an hour of use.
[Transformer TF300T Android Development] timduru:
okie, so at least it helps for your model.. cpu_process:1 !

you're the first I see with that model x_x

Weird weird... how comes it doesn't fix for cpu_process:2 like yours and [MENTION=4594874]desireleß[/MENTION] ...

Any changes at all with the 10-11-12 kernels or nothing, nada ?

Like do you still see the flickering on the Asus boot screen for example.

When does flickering occur, does it occur more / less / the same

what is its frequency ? every few seconds, every few minutes, a few times per hour, every few hours ?

Does putting the lower freq to 475 still fix it ?

The more info you give info the better,

because I don't understand how some of these modifications in the last 3 kernels can not at least help a bit the flickering.

Unless there's some big asus hack somewhere that I missed for cpu_process:2 that makes it not follow anything like the others maybe...

Another thought: are you sure you didn't have flickering on rom V012 ?

Maybe you are paying more attention to it after it flickered in V013-V014 ?

Anyway, those who have the issue, just to make sure, try this -t13 kernel: Tim_KatKernel_030-t13_TF300T_MM6.0.1.zip

and get me back the cat /sys/kernel/target_info/info with that kernel

and also if you can remind me what was your target_info with the other kernels for comparison
[Transformer TF300T Android Development] Salamender:
Thanks for that awesome ROM !

After i flash GApps, when i reboot, i have a Setup Wizard force close and i can't make anything on my tablet... Any ideas ?
[Transformer TF300T Android Development] Ctrl-Alt-Del:
No flickering using V012, 99.9% sure.

Using min freq 475mhz fix the flickering issue with any kernel version

Lowering min freq to 102mhz seem to fix it also.

gpu-t10 = flickering like gpu-t8 kernel but less than t1 up to t7 (1 time/hour)

gpu-t11 = flickering and slow (every few minutes)

gpu-t12 = flickering (1 time every 15 minutes)

Hi Timduru,

Don't know if someone else mentioned that when the tablet start or reboot with wifi on, it's taking a very long time to connect. I have to open the Quick Settings panel and click below Wifi to show all network available to make it connect instantly. Also, using Bluetooth in Quick Settings does requires clicking twice to make it work. The same behaviour applies in Settings panel.

Here's what I have to do to activate Bluetooth in Settings panel;

1-Click Bluetooth

2-Click activate

3-Click back arrow

4-Click Bluetooth

5-Click activate

I'm not sure if the problems where present back to V012.

[Transformer TF300T Android Development] Berend de Boer:
Did try that on #14, but that doesn't work for me. Also not sure flickering describes the right thing, it's more like a very brief sideways traveling of white line, more like tearing.

---------- Post added at 09:05 AM ---------- Previous post was at 08:41 AM ----------

I got the tearing usually straight away, but nothing so far! Using on-demand governor.

$ cat /sys/kernel/target_info/info

soc_speedo:2, cpu_speedo:5, cpu_process:1, core_process:0, project_id:2
[Transformer TF300T Android Development] pe1dnn:
I don't think this is the issue others are seeing, at least I do not recognize this. Also your cpu_process: value is different from the others having this problem. I never saw a traveling white line on mine.

Like I said I do not see it often but when I see it its just a very brief instability showing a black horizontal line from left to right. But I have not seen it on mine with the recent test kernels (now running -t13) so I can't record it.

It would be nice if somebody could make video of it because if we experience totally different things but call it the same then it would explain the confusion. Describing it is always hard. Recording it would maybe also give a clue where to look for by analyzing such footage in more detail or in slow motion.

[Transformer TF300T Android Development] Clamor:
No, there is no compatible kernel:(
[Transformer TF300T Android Development] macavita:
Do you know if there going to be a compatible kernel??
[Transformer TF300T Android Development] timduru:
Booting wise, I've added partial TF201 auto-detection in the kernel

it might actually work depending on the kernel.

I'd try this for the TF201:

Full wipe with format of /data to f2fs

Flash the Rom V014 as is, see if it boots

If it doesn't boot try the -t10 kernel posted a few posts above, it contains more freq fixes.

If it doesn't boot try -t13 just in case, that one doesn't have auto-detection but have different freqs too.

(we're talking about testing booting first here, camera, wifi and such might most likely need tf201 specific adjustements then)

Post me the results BY Private Message.

I don't wan't TF201 posts to pollute this thread

It has gotten complicated enough with the flickering issue ;)

Good news is that -t13 seems to fix the flickering issue for all models, so I'll go with that in the next rom version.

Once it's fully confirmed , I can see about maybe adding more goodies back in test kernels based on that kernel .
