Prime video app problem...

I have looked in this thread and others so forgive me if there is a fix... but I am having trouble with the Prime Movies app... on my TF300T with Nougatella. It opens, and plays my selected video for a random amount of time (1 to 10 minutes) and then stops responding with a black screen. If I close the program that is not responding (Prime Video) it kicks me back to the video selection screen... and I can play it again with the same results until it crashes again. Any ideas?

I have no problems at all with Youtube, Netflix and Hulu. Besides that everything is working great, no problems with wireless or the dock keyboard/mousepad etc... for those having trouble I'd try clean flashing again following the listed procedures, seems like sometimes the second time's a charm!
[Transformer TF300T Android Development] Catscratch:
If I remember correctly there should be a hardware button to de/activate the keyboard. Or only the touch pad? Maybe have a look for that button.
[Transformer TF300T Android Development] scruffy1:
settings > languages and inputs > physical keyboard > keyboard layouts is where the options lie; maybe choose a different layout and see if that gets any response

there is indeed a hotkey in the top row of the dock(4th from left) that switches the touch pad on and off, but no keyboard key

as with all problems, first ascertain that the dock is correctly "docked", as they can be rather temperamental

then i would suggest the easiest bet is to simply reflash the rom... sometimes that will remedy otherwise inexplicable issues - cheap, easy, and if successful... not unusual

2 x tf300t's here running 7.1.2 quite happily :)

Hi

I have tablet ASUS TF300T, it's rooted and running KatKiss ROM 7.1 Nougat. I'm trying to use Airaudio to stream my music to my

wi-fi speakers (Aether Cone) but there isn't no music in my speakers. I try to explain the situation.

If I play music, I can hear it in tablet speaker but if I launch Airaudio app, I don't hear music neither in tablet speaker neither in

wi-fi speakers.

I tested other KatKiss ROM but I had same result.

Just for information, if I use Allconnect in my tablet I hear music in wi-fi speakers (same speakers, same lan), but I don't like this app.

I have explained the problem to Airaudio developers and they gave me this reason:

"This sounds like the "remote submix"-audio-route is wrongly configured inside the KatKiss-ROM.. that's sadly something that cannot be

changed in an easy way."

Can you help me???

Thanks for cooperation

Hi

I have a question about the dock for tf300t because i have an issue about the touchpad especially the buttons that dont seem to work when I click.

Is it normal and it is a bug to be fixed in next update?

My seconde question is less important but is it possible to change the color of the save mode with its Orange band or remove the color (maybe a new feature to change or disable its color)

Thanks

Question, why can i only install the pico gapps? because i want to install the Stock gapps package but it giving a error about some partition space, could somebody help me?
[Transformer TF300T Android Development] Babbsack:
Yes, the larger gapps packages won't install due to the missing space. Use the search function in this thread "gapps" and you get more specific answers.
[Transformer TF300T Android Development] ebonit:
It's because of the limited memory of the device. Therefore keep the amount of apps as low as possible. With view on the performance usage of memory should be on average never more than 70% of total memory. Please keep that in mind! :cowboy:
[Transformer TF300T Android Development] pe1dnn:
To elaborate a little more on the supplied answers so far. You may think how can 32GB be limited memory? This is all about the system partition size. Gapps installed via TWRP ends up in the system partition, where it is a fixed part of the system (you can not uninstall it in Android). The system partition is just barely enough to hold Android and pico Gapps. So a bigger Gapps package does not fit.

Repartitioning the drive to increase the system partition could solve it, however this breaks so much when you want to switch or recover that this is not advisable at all. None of the TF300 roms I know of repartition the drive because of this and therefore do not mess with the partitions.

However what is the problem? The other parts of the Google apps can be installed with Google Play afterwards, these will go to the data partition so this will therefore fit easily.

Note that updates of Gapps packages will go to the data partition anyway so it is actually a plus to have only a small package in the system partition. See, if you would have full Gapps on the system partition and after a while all packages got an update, then you effectively have all packages twice; an outdated version on the system partition and a current running version on the data partition. So instead have the bare minimum on the system partition to have the Gapps core and Google Play to get going and then install the rest and updates from Google Play makes a lot of sense.

So Gapps Pico it is and install the other Apps from Google Play.

Hi guys

Any help for me?

Thanks a lot
[Transformer TF300T Android Development] Neolyum:
Hey there, I have a little Question.

In order to flash this ROM, I must flash the KANG Recovery, it says it must be on bootloader ending on 27.1 or 27.5.

I think my bootloader is

android cardhu-user bootloader <1.00 e> released by "WW_epad-10.6.2.11-20131213" A03

There is no "27" in it, so I am not sure if it is the right one.

At the moment, there is a Cyanogenmod 12 Nightly installed (Android 5).

In post #1519 https://xdaforums.com/showpost.php?p=67476226&postcount=1519 someone has the same version as I have, but I want to be sure that I have it right, because I dont want to have a brick :D

Thanks :)
[Transformer TF300T Android Development] gc2712:
To get the latest bootloader you wll need to reflash latest stock rom from Asus for your machine. [I am assuming its a TF300T] Just search "stock" on this thread for several references eg. https://xdaforums.com/showpost.php?p=75003570&postcount=1344

Once you have the latest bootloader which stock flash installs, just go through the procedures in the OP for installing Kang TWRP.
[Transformer TF300T Android Development] Neolyum:
Because of two more people with the same bootloader I tried the installation with my version and it worked flawlessly! :)

I am now running a stable smooth system, thanks for that ^-^

But I'll keep this in mind, if I need to update my bootloader sometimes.
[Transformer TF300T Android Development] gc2712:
Glad to hear it worked out without the hassle of flashing stock and updating bootloader

Boot Loop

Hey, I have tried to flash and reflash this rom. No matter what I do and what steps I go through I keep getting a boot loop. After flashing and rebooting, It makes the tablet (tf300t) seem posessed. It flashes the flashlight, and the screen turns on and off and reboots and does that over and over again. What the heck am I doing wrong? This has been keeping me up at night forever now! Any advice? I used Kang twrp, changed/data to f2fs, made sure it was the right version of the rom, etc.
[Transformer TF300T Android Development] timduru:
The TF300T doesn't have a flashlight, so you're most likely flashing the wrong version onto it.
[Transformer TF300T Android Development] tymulungu:
WOW! This whole time I have been thinking that it was a tf300t. For years! But now that I look it up online, its definitely not! It is definitely a transformer though because it has the keyboard dock ports. Do you know what model doesn't have the complete aluminum back? like mine has the plastic bar across the top where the camera and flash are.

EDIT: Nevermind! I swear I must be dyslexic or something. I hadn't put a custom rom on my tablet for years and came back to put this one and my brain automatically said "yeah, it was 300, no doubt about it" but it was actually 700 haha. I'm gonna try flashing that version now.

[Transformer TF300T Android Development] ojdon:
Awesome work! Runs beautifully on my tf300t! Thank you for keeping tf300t supported.

Such a shame that this device crawls to a halt as soon as it needs to write to the flash storage. Does anyone have any tricks to reduce the flash storage bottleneck for this device?
[Transformer TF300T Android Development] scruffy1:

[Transformer TF300T Android Development] Beonico:
Here are some tips to make it run smoothly:

1. Enable the Zram option from the Performance tab.

2. Install the Greenify app. (Don't forget to enable it as a service ! in the Accessibility tab) Let it snooze as many as possible apps. Look for the app's with an active background.

3. Install the ES task manager. With this you can control the startup process. Disable all apps you do not need to run constantly. It will speed up the boottime.

4. Get the BackgroundRestrictor app from XDA labs. With this you can control the allowed backgroundprocesses. Disable all backgroundpermissions except for constant polling apps like Gmail etc.

If some app doesn't function like it should, just reverse the backgroundsetting again.

5. Enable the "Developer options" in the configuration menu (7 or 8 times tapping on "Tablet info") and change the option "Backgroundproceslimit" from Standardlimit to max 4 processes.

This setting is unfortunatly not permanent, so you have to set it each time after booting.

6. Install the "CPU Stats" and "Ram Meter" app's from the Google Play store, this will show you the memory and CPU status in the notification bar.

Doing this, the memory of the TF300 will be kept as clean as possible, such having maximum space for the running app.

Used memory should be inbetween 60 to 80 percent. Above 80% you will notice lag issues.
[Transformer TF300T Android Development] ebonit:
To my opinion this might be the most important advice. With view on the very small memory (950 MB) there is a well known rule within the circle to keep the amount of apps as low as possible. It can be controlled easily by Settings -> Memory. See screen shot! No other apps needed.

An other important thing is the Performance setup. I'm using the stock Governor (interactive), minimum (204 MHz) and maximum (1500 MHz) speed. No ZRAM! No idea if that speeds up anything. Please check your settings finally.

Go to Performance:

Set clock values on boot

Set Governor on interaktiv

Minimum frequency

Current value: 204 MHz

Maximum frequency

Current value: 1500 MHz

Boot value: 1500 MHz

I/O scheduler current value: cfq

Set value on boot

I noticed the same problem with the microphone. The amplification is too high causing audio distortion. Have you resolved this problem since then? [MENTION=5354919]gc2712[/MENTION]

Most forum discussions talk about changing config settings in build.prop file, but the referred configuration entries were missing from this ROM. I even tried to add them and reboot the tablet after that, but nothing has changed.

Also I can confirm that making audio calls with a headset works well and gives good sound quality.

Is there anything else I can try to do?
[Transformer TF300T Android Development] gc2712:
Sadly, I didn't ever find a solution and no-one on this thread offered anything or even responded to my query. I have given up and use my headset with mic built in. Very sorry I couldn't fix it as, thanks to this rom, the tablet is now my primary device
[Transformer TF300T Android Development] timduru:
Can you pinpoint the exact rom version where it started happening ?

I can try to have a look at the diffs in that case.

Also did you try "reinit FM34 DSP " in the K.A.T app, (

after

you have started the app/call)
[Transformer TF300T Android Development] gc2712:
I really appreciate the follow up. Unfortunately, I can't remember where the sound issues began. (Grey hair issue I'm afraid) I have been using your ROM for a long time now. It might have been as long ago as #18. It was certainly no problem back at #12 though.

I had tried "reinit FM34 DSP", but not during a call I think.

Hello, I wanted to try this updated Rom, so I did a wipe of the Dalvik cache, system, cache, data (f2fs) and internal storage. Then flashed this Rom, supersu, pico gapps...

I installed facebook, Snapchat, Instagram, Twitter, word with friends, etc. 58 apps total. The above mentioned apps take very very long to open up with such a lag loading data.

Ive tried the suggestions above and on the previous page to speed things up. I do not see any improvement.

Am I missing something or is it the tf300t can no longer handle these big apps mentioned?

Thanks Tim [MENTION=3951330]timduru[/MENTION] for all of your hard work. You gave me several years of extra life out of the tf300t!
[Transformer TF300T Android Development] ebonit:
Hello Sindee75! Good to see you again here in the thread. :cowboy:

I think you should know where the catch in it is located in your case. Wipe in general is mostly too less to get a clean system. The device needs a Format Data from time to time in order to improve the performance. So I would like to advise you to do following steps:

1. Start a Format Data through Kang TWRP. Be patient, it may take up to one hour to be done successfully. (see screenshots!)

2. Change file system to F2FS for Data only, no system, no cache.

3. Install Rom, pico Gapps and SuperSU again

4. Keep the amount of your apps as low as possible

Hi guys,

great work again!

I only have one issue .. the setup assistand doesn't work and always stops. I can't do anything else. I tried different languages and both options "Copy your data" and "Set up as new".

I did a format data and set up completely fresh!

Had this issue with Katkiss 27 and also with 28.

Any ideas how to solve it?

I am using KatKiss v.25. tf300 with keyboard. I have always had the feeling that android never really shuts down. I power off. If I come back a few days later, it won't power on because the batteries are dead. Plug it in, let it charge for a while and it is fine.

Is this normal for android? Is something always running in background?

Is there a setting that I need to change to make power down really power off?

Thanks for the Update and a small query from a newbie.

Very recently I installed Nougatella #027 and must thank timduru for a very professional update. As everything is working extremely well I ask is it worth updating to Nougatella #028 as it means a complete wipe and install of some 50 apps?
[Transformer TF300T Android Development] ebonit:
Nope! :cowboy:

Nougatella #28 is a security update only. If there haven't been any issues with your current version, you may simply do a dirty flash as advised in the install instruction in post #1:

-Flash Rom, SuperSU and pico Gapps in one run,

-After that wipe cache/dalvik

Mount namespace issues

If you see this line in the Magisk log: "proc_monitor: Your kernel doesn't support mount namespace", your device has a Linux kernel that is to old. The Linux kernel version have to be at least 3.8 (thank you TheCech12), or otherwise have the necessary features backported. Ask in your ROM/kernel thread or try a different ROM and/or kernel.
​

Is this something that is possible?
[Transformer TF300T Android Development] MiniBlu:
No, magisk won't work on any roms for tf300 as the base kernel version is to old. You would need to convince ASUS to update kernel sources (which will never happen)
[Transformer TF300T Android Development] Clamor:
Not necessarily, Transformers already have 3.4 kernel available :p , but it needs more work to be done.

P.S. Magisk works perfectly on Unlegacy ROM
[Transformer TF300T Android Development] MiniBlu:
To support all magisk functions properly you need kernel version 3.8 or higher (not 3.4) and in my experience the 3.4 kernel base from tf700 that was ported to support tf300 was quite buggy.
[Transformer TF300T Android Development] Clamor:
OR(!) backported feature to 3.4 and BTW TF700 has 3.1 kernel as well.
