tiger_duck, thanks, you pointed me in the right direction, move didn't pop it up, but typing jump into the search did, thanks for the advice.
[Transformer TF300T Android Development] nbenm:
You are right. These options are necessary, and CONFIG_USB_SERIAL_FTDI_SIO too.

FTDI_SIO module is needed.

Do you think it could be possible to add it in next kernels ?

Serial communication with all Arduinos is done this way.

Dock stop charging top....Have somebody same problem?:(
[Transformer TF300T Android Development] knypo:
Hi,

1) is it possible to disable that "search" box placed in the top of the screen?

2) is it possible to hide that pull up application menu which is in the bottom of the screen?

3) if i want to update from version let say #15 to #18C do i always need to format data? Or is it enough to just install new rom, gapps and supersu?
[Transformer TF300T Android Development] ebonit:
Please read the install instruction in post #1!

If you don't have any issues with your current version, you may do a "dirty flashing" of the update version:

Flash Rom, SuperSU , Gapps (pico) in one run, then Wipe Cache/Dalvik and Reboot!
[Transformer TF300T Android Development] Iceman_jkh:
Has anyone with a TF300TL got this ROM installed and working?

I don't think it's a Katkiss issue actually. More so the issue is finding a fully compatible recovery.

Its so great to have camera and video back again on #019! I can see family overseas again. So grateful. Also, don't have to install another launcher again to get rid of search bar on home screen. Brilliant! :)

Ditto for my TF700 which I am also updating as I write this. Many thanks for continuing development timduru

Hi guys

I use TF300T with KatKiss 5.1.1_028 for quite a long time. More than a year.

It worked very well but strange things started happening with it during the recent month. It stop responding sometimes and I had to make hard reset (vol- + power) to bring it back to life.

So, I think it is good time to clean it and switch to newer KatKiss.

I need stable version to work the next year or so without issues :)

What do you recommend? KatKiss 6.0.1 or KatKiss 7.1.1? Which is more stable at the moment?
[Transformer TF300T Android Development] ebonit:
Finally it's up to you which one of both you are willing to use. Both are stable with a very good performance. However with KatKiss 7.1.1_019 you will be on the latest Android 7.0 level.

Please take care of the install instruction in each post #1. You need Kang TWRP 2.8.7.2!!! Don't forget format /data in order to avoid any issues.
[Transformer TF300T Android Development] -JP-:
Hi, I just did a clean install of:

KatKiss-7.1_TF300T_019.zip

open_gapps-arm-7.1-pico-20170310.zip

UPDATE-SuperSU-v2.79-20161211114519.zip

However I'm unable to link my google account anywhere? (to install additional apps)

In the previous rom versions I went through a setup procedure after the initial boot. This time it went straight to signed in as Owner?

Does anyone have an idea where it went wrong?
[Transformer TF300T Android Development] ebonit:

Thanks for the quick reply.

On further investigation it seemed my gapps file did not have the correct checksum.

I did a new clean install and everything is running as expected now.

:)

one thing I am missing since lollipop is the "right click sends back" feature..

maybe it is possible to implement it?

thx for the uncountable hours you spend on this ROM [MENTION=3951330]timduru[/MENTION]
[Transformer TF300T Android Development] ebonit:
Please have a look at this post https://xdaforums.com/showpost.php?p=71376999&postcount=170

I think you didn't format /data as recommended in the install instruction. Further on reduce your apps on a minimum quantity.
[Transformer TF300T Android Development] Markic:
I try again, but i pretty sure that i completed format/data clean.
[Transformer TF300T Android Development] mloc33:
Just curious what other people's memory usage is like, my tab is unbearably slow.
[Transformer TF300T Android Development] ebonit:
First of all, both screenshots look fine. To my mind the ram usage is even borderline. You may reduce the amount of your apps as low as possible. It might not be the reason for being slow.

KatKiss-Nougatella shows a great performance in general. First of all, please check the performance settings on your tablet:

-set clock value on boot aktiv,

-set Governor on value interactiv,

-Minimum frequency 204 HHz

-Maximum Frequenz 1600 Mhz

-I/o scheduler on value cfq

To be sure check if data is on file system F2FS:

(You can go to the recovery and do this: Wipe -> Advanced Wipe -> Select partition you need to see -> Repair or Change File System. You will see there is "Current file system" information.)

If the device is still slow after that, you should do a clean reinstall of this rom after format data

Please have look at this post too: https://xdaforums.com/showpost.php?p=71094836&postcount=615!

There is a special part: Usual tips and what I do myself, by Timduru.
[Transformer TF300T Android Development] supercar1:
I wanted to thank timduru for the amazing work he has been doing for the last years.

I always felt the tf300t a little slow (maybe because I'm used to a faster galaxy s6), but today it happened something very strange with my tablet.

First, I was using nougattela 15, and I don't use my tablet too much, maybe once or twice a month, but yesterday I started using it to show some pdf files while I was studying. Today, I brought the tablet to school, because of the same reason, and all good! Then, at lunch time I restarted my tablet because the wifi wasn't connecting to my school's network. I pressed the power button, and selected restart. Then, the usual asus logo... but it took a lot of time! And then it restarted, and more asus logo, and restarted, and asus logo, and it went on and on... Then, I tried to power button + vol down, and I had the 3 icons, so I selected rck, to go to the recovery... Then, surprise surprise! It showed "teamwin" for a while, but then it restarted again, to the asus logo!!

I have no idea why this happened, as I didn't change any files or anything... I did some searching in the foruns, but I don't have time in these days to "unbrick" the tablet, because of school and tests... And using fastboot, going back to stock rom, and installing again nougatella seems like a lot of work that will take a long time... The thing is: why the hell did this happened? And is there any simpler solution to my problem?

Thanks in advance, and sorry for this being the first post in xda, but since a long time (since Lollipop), I've been using timduru's roms, and they give a new life to this tablet!
[Transformer TF300T Android Development] mloc33:
So my file system is ext what should I select when changing it to f2fs and will it delete any info on internal storage?
[Transformer TF300T Android Development] ebonit:
Sorry, wrong message!
[Transformer TF300T Android Development] timduru:
you need to select wipe => advanced wipe,

check /data then "Repair or change filesystem" => change file system => and choose F2FS

it will then format /data to F2FS , internal storage being in /data, yes, it'll clear it so backup first.

But that's why changing to F2FS is part of the install instruction...
[Transformer TF300T Android Development] mloc33:
For some reason, I thought I was already on it.

Edit: I'm back up and running,just restoring apps,I'll see how everything is once I'm back to normal. Thanks everyone!
[Transformer TF300T Android Development] walttheboss:
I am on 19, clean install. Great ROM. I am in China where Google is blocked and I think that it is keeping the tablet awake and the android system is consuming way too much battery. Attached are the detailed reports from GSAM battery monitor on the two too offenders on my battery. If anyone has time to look that would be a big help.

I was on 29 before and the tablet would go 8 days on a charge at the same usage level. Now I get two days.

Problems with CPU-overclocking

I made a clean install of #019 and wanted to overclock the CPU up to 1,7 GHz without success..

I left the minimum frequency on 204 MHz, but noticed that it never goes below 475 MHz :rolleyes:
[Transformer TF300T Android Development] timduru:
1.7 seems to work ok on mine, maybe try to set it on boot and reboot .

problem with 1.7 is that it will tend to overheat and hit thermal throttle, I think it throttle at 1200 in that case,

so if it's short bursts it'll be ok, but if it's constant load it kinda will behave worse than leaving it at 1500.

It seems it doesn't go lower than 475 indeed though, seems to be offset +2 most likely related to the 2 lower freqs revert,

have to see about that.

[Transformer TF300T Android Development] cluedo97:
So I am running out of ideas. I can't get any rom to install on my tf300tg. Everything seems to go fine except when you actually booting up the rom, but in my case it's just bootloops. I get no errors and I have tried different twrp versions and also different roms, supersu and gapps. The only firware I am able to install is the stock firware that you install via blob file.

any ideas or tips that I can follow. Really getting irritating
[Transformer TF300T Android Development] Matchless 2015:
Did you follow the steps

exactly

as given it the first posts of this thread? If you are a trying "different" versions from those suggested then anything can go wrong.
[Transformer TF300T Android Development] ebonit:
[MENTION=8142826]cluedo97[/MENTION]

Be sure that you have Kang TWRP 2.8.7.2. Then

format /data

using Kang TWRP. Change file system to F2FS (Data only!). After that follow the install instruction in post #1 carefully as recommended by Matchless 2015.
[Transformer TF300T Android Development] walttheboss:
To add to what [MENTION=7106193]ebonit[/MENTION] said. Be aware that the format data step can take an hour. Just keep waiting. When you format it becomes ext4. Then the change to f2fs can go much faster.
[Transformer TF300T Android Development] ebonit:
Regarding to SyncLoopWakeLock it seems really to be the reality in your case. I have been watching my battery for 24 hours. So I can provide the screenshots after that. However I have to add that I have been using the Naptime app as recommended here: https://xdaforums.com/showpost.php?p=71446302&postcount=707.

My final conclusion is that the battery drain of version #19 is absolutely normal on my tablet after clean install.
[Transformer TF300T Android Development] cluedo97:
I have twrp 2.8.7.2 and I have now formated succsesfully. And then I changed data to F2FS. I then installed the rom then the supersu and then the gapps with no errors. but it bootloops anyway.

Is there anything else that could have gone wrong?
[Transformer TF300T Android Development] timduru:
New Version #020

New rom version available: KatKiss-7.1_TF300T_020.zip

Note that apps are going to get optimized in the background after the upgrade and first boot into android,

so better wait and let the tablet settle down for a while.

Note for those who have "lag" with their apps, try this version first and see if it helps, as tuning has been changed.

If you still have too much lag, try to enable zram in Settings => performance and reboot, kernel settings have been changed to allow swap too.

If your lag case is because of piggy apps, it should help.

Overall make sure you've read all the tips posted previously too.

Changelog:

- Fix Green video thumbnails (on dirty flash: will require to clear Data of Apps: Media Storage + Gallery + reboot in order to be regenerated)

- Launcher3: add more settings (long press on Desktop to access):

-- Disable all apps pull up

-- Show all apps icon in dock (if you activate and have an icon in the center slot, you'll need to move it)

-- Enable search on pull down

-- Enable transparent dock background

- navbar: add longpress logic && refactor NavigationBarInflater

- UITuner - navbar: allow to set custom LongPress actions on Buttons

- UITuner - navbar: add new predefined layouts:

-- Left aligned with default LongPress actions (kill on back and switch top floating on switch to previous app btn)

-- Left + centered + Balanced buttons

- Settings: add ActionPickerActivity

- tablet-dalvik-heap: constrain growth limit to maxsize*target/2

KatKernel TF300T, TF700, TF201 #047:

- reuse 128 read_ahead

- vm tweak reboot

- allow swap

- Revert "mmc: sdhci: Do not allow tuning procedure to be interrupted"

1. What time took format data?

2. Did you flash Rom, SuperSU and Gapps (pico) in one run using Kang TWRP or each .zip file seperately?
[Transformer TF300T Android Development] cluedo97:
1. it took about an hour

2. I installed them in one run
[Transformer TF300T Android Development] PhilSanc:
Hello,

Just applied the procedure (I'm a rookie and it was first time for me to install TWRP and upgrade my tablet).

I succeeded in installing KatKiss. Got an error message first time I boot on KatKiss as it seems that some applications were slow to launch but it works after. :good:

I will do few test to restore then all my apps later on.

PS: I realize that I haven't change filesystem to F2FS (I saw on different post that depending on version of TWRP, sometimes you have to let existing FS so I was not sure). What is the impact and if F2FS is recommended, could you do it afterwards (or if I set it later, do I need to redo the full install procedure of KatKiss and App)? :confused:

Please note that I used kang_2.8.7.2.

PS2: I also realized that now my tablet isn't recognized anymore by my PC (driver issue). Is it normal (sorry if this question was raised previously, I'm new in this forum and activity :o ).

Regards.
[Transformer TF300T Android Development] walttheboss:

[Transformer TF300T Android Development] gc2712:
Might be a dumb thought, but did you check the md5sums of the downloads to make sure they are uncorrupted? Try another build of Gapps?
[Transformer TF300T Android Development] ebonit:
First of all, having Kang TWRP 2.8.7.2 is fine! So you may follow the install instruction in post #1 carefully. Format data firstly and then change data file system to F2FS. This step is part of the install process and shouldn't be done afterwards. Please look here: https://xdaforums.com/showpost.php?p=71428194&postcount=702.
[Transformer TF300T Android Development] Thunderbolt.00:
I'm at a loss

TF300TG, did everything exactly like the OP said, formatting data took about 30 minutes, installed all the zips separately (but without rebooting), and when I tried to boot to system it got stuck on the loading screen, restarted and now I'm in a bootloop.

AND when I try to enter TWRP, it shows the loading screen for a while, crashes and bootloops again :I

I guess I can go back to stock with fastboot, but I'd really like to know what I'm doing wrong, why isn't it working for me when other people said it worked on their TG's

Also another thing I noticed, when I first rebooted after installing the zips, there was a loading bar under the ASUS logo that looked exactly like the one I had after I installed TWRP using the terminal/reboot method. Could that have something to do with breaking my recovery?
[Transformer TF300T Android Development] walttheboss:
You said you formatted data. That changes it to ext4. Did you THEN change the filesystem back to f2fs. You need to do that after formatting.
[Transformer TF300T Android Development] Thunderbolt.00:
Yes, I did everything exactly like in the instructions

Tried reflashing TWRP using fastboot now, still won't load.

I noticed something interesting though, when it's trying to load I get a message below the four Linux logos which I don't remember being there before, could that help with anything?

[4.662338] [elan]detect intr=>Old FW
[Transformer TF300T Android Development] walttheboss:
Yeah well done. Something fluky going on. You already unlocked bootloader and were on latest? I guess you did all that.

Did you check all the md5 sums for all downloads?

I guess its back to stock. Then try again. Also try a different sdcard. This tablet had a bad reader and it can mess up.
[Transformer TF300T Android Development] Thunderbolt.00:
Yeah, everything unlocked and latest version. I've already installed CM on this device before but it was slow and unstable, so I thought I'd try this ROM, which doesn't seem to work at all for me.

Thanks for the help though, I might try installing everything from an OTG flash drive this time
[Transformer TF300T Android Development] walttheboss:
And check the md5 sums to eliminate a bad download. Good luck. Its worth it. Way better than cm
[Transformer TF300T Android Development] cheaterel:
Hi with v20 it works better in v19 I was having lag

PS I have zram on
[Transformer TF300T Android Development] ebonit:
I have been follow the chat between you and walttheboss. Very interesting result with view on that code "[4.662338] [elan]detect intr=>Old FW". What does it mean exactly? I have never seen it before.

Regarding to your OTG intention I am wondering whether your device is OTG suitable? I have never tried such a drive on the TF300T.

PS: Are you sure that you really have Kang TWRP (twrp_tf300t_kang_2.8.7.2.img), because Kang TWRP, developed by Josh, is different to TWRP in general you mentioned several times?
[Transformer TF300T Android Development] Thunderbolt.00:
Yes, I installed the one linked in the OP, and everything up to the point of actually booting into a new ROM works fine.

And I bought some cheap Chinese OTG adapter for the TF300, flash drives and controllers work as they should in Android so I'm assuming they'll work inside the recovery as well.

I still can't understand why installing the ROM made the recovery crash on startup as well, forcing me to go back to stock. Could it be something to do with the kernel? Is that even loaded when going into recovery?

Also I think that "[4.662338] [elan]detect intr=>Old FW" message can be ignored, I just reinstalled (Kang) TWRP alongside the stock ROM, the message shows up and everything still works fine, so I guess it's not connected to the crashes

Thank you very much indeed for version #20 and your advises in the issue note.

After a clean install this version runs very smoothly with a further progress on performance. I don't use the swap because I have never before experienced any lag on the previous versions.
[Transformer TF300T Android Development] Markic:
#20 is much better version than #19. I currently have very small lagging. I believe it will better on #21. Thanks [MENTION=3951330]timduru[/MENTION] for best ROM. Good luck in future
[Transformer TF300T Android Development] Matchless 2015:
My TF300TG is running properly on 7.1.1 v019 and I also get the same when booting into recovery; 4.652241 [elan] detect intr = Old FW.

I think this may be related to the firmware already installed on the touch screen controller card and TWRP which uses the touchscreen. I did replace my touchscreen 5158N with a G01 type and updated the touchscreen firmware to 02-3011-4820 about a year ago.

It does not affect anything on my TG except for this message.
