On later versions there is no touch folder it seems. You can put the file in any folder and then flash it from that folder.

Example: touch_fw_update command -u /data/local/tmp/02-3011-4820.ekt (You must be SU in the terminal)

Here is a very long thread https://xdaforums.com/showthread.php?t=2091233

If you start from about page 90 onwards it may give you some idea or preferably read the whole thread before you jump in.

Hope this helps.

i tried that mate but it says the touch_fw_update connot be found so i think i need a stock custom rom

OK, so I downgraded back to KK 5.1 Marshmallow #30 and there was a very noticeable and positive difference in the responsiveness of the tablet. This version does have split screen mode available so the lagginess may not have anything to do with that feature of the OS as such.

I'm torn now as Tim has put so much work into keeping us up to date with the latest OS which of course comes with security fixes etc. and I definitely don't want to sabotage that by suggesting people ditch Nougatella. It is an eye opener for me and makes me wonder if it's possible to have the best of both worlds, ie. latest OS that is also as snappy as Marshmallow was.....yeah, I'm sure that Tim hasn't thought of that he says tongue firmly in cheek.

Thanks for your work Tim. :good:
[Transformer TF300T Android Development] walttheboss:
Maybe possible to have two versions. If multi window is an issue then one zip could be super basic made for speed and another zip for features.

For me the lag just comes over time. Fresh install of any version is snappy for a while.

My use is basic so I don't mind. Thrilled to have this Rom.
[Transformer TF300T Android Development] jokemeister:
Interesting as my experience is that once I've reloaded the apps I pretty much get what I get straight up. I've tried clearing caches for the apps that I use such as Flipboard as that's been flagged in various forums to speed up Flipboard back to as new but that only had a very temporary effect and it was soon back to laggy. Mind you, I only do a fresh install between major OS updates. All updates for a particular rev like Marshmallow or Nougatella are dirty. I never did quite understand the exact steps to successfully back up and restoring all my apps and data rather reinstalling everything. I'm no idiot when it comes to computers but Linux (and its derivatives) has somehow always confused me with its file structure and file handling compared to PC. I know there'll be people rolling their eyes at that, but somewhere along the line I missed something fundamental to the building blocks of understanding Linux and MOST guides are written by people who take it for granted that others understand what might be simple steps to those that know but are in fact complete unknowns to those who don't know so it gets glossed over, eg. mount a drive. In the PC world you don't need to do this as the OS does it automatically but on a Linux system there's every chance you'll do this at some point. That may be a bad example and simply highlight my ignorance but I hope you get my drift.

[Transformer TF300T Android Development] gc2712:
Sorry for the noob question, but how do i uninstall Google search? Maybe I have already and forgotten (a grey hair thing) but I can't find any app that relates to search to remove.

Very grateful for continuing development for these devices and your comments on resolving "laginess" which so many seem to be experiencing.
[Transformer TF300T Android Development] thorrules:
If you use Pico gapps then you shouldn't have google search (unless you installed it later, in which case you can just uninstall it like any regular app)
[Transformer TF300T Android Development] gc2712:
Ah! Of course. I did use pico Gapps :p

Many thanks. sorry about dumb question
[Transformer TF300T Android Development] walttheboss:
Wow! That's a great response. 8 years on XDA on 6 different devices and never saw that. Thanks [MENTION=3951330]timduru[/MENTION] for the great Rom and commitment. We all appreciate it a great deal.
[Transformer TF300T Android Development] thorrules:
Great ROM!

[MENTION=3951330]timduru[/MENTION] I would have long recycled my tablet if not for your wonderful ROM support. Honestly I don't need this tablet and I barely use it once a month, sometimes even less, but I am going to keep it as long as you support this device. Just now flashed Nougat, watched Star Trek and now it is going to just sit idle for another few months until you release Android 8 :) :good: Thank you so much!!!

Same problem here on #18b. After a while tablet goes to sleep, wifi connection is completly lost. Turning wifi off and on doesn't solve it. Turning on wifi doesn't work. It keeps trying to turn on wifi, but that fails. Reboot and it works again untill the tablet sleeps.

Otherwise this rom works great! Compliments [MENTION=3951330]timduru[/MENTION] and thnx for the hard work
[Transformer TF300T Android Development] jokemeister:
Thanks Tim. Never meant to imply you weren't doing enough and I hope that wasn't the way you read my post. I think its clear from what I'm reading that we are all very grateful for the time and effort you put in. Thanks for posting the video. The issues I'm seeing are obviously related to the apps I'm using and possibly even the settings I've chosen because my tablet sure wasn't responding like yours by a wide margin. Looks like I'll be going through a fresh install and then installing one app at a time to see whats what and find the piggy.
[Transformer TF300T Android Development] doldi:
Hello timduru and ebonit

i had a big problem with my TF300T - on 18.02 tablet hangs up total with #15 - no respons.

Ok-think no problem - will install the new Vers. with Kang TWRP but "Data" in System was unable to mount/unmount ....pah.

after some search here on Forum i found the solution - format all folders seperatly, download the org. asus firmware and extract from this big zip-file the "blob" file. After flashing them /also twrp i was able to install #18b :cool:

Nice, very nice - but i can not install any apk - Playstore ore from SD/network/usb - nothing.

Ok, think i go back to the old MM6.0 - also absolut a nice work - but i have no chance to install them, pah...

What have i to do?

Over TWRP i put an old backup, yes - noe we can ;) but it works now a little slowly.

best regards

Harald
[Transformer TF300T Android Development] ebonit:
Hi doldi, welcome in the XDA community!

After all your efforts I think the best solution would be a clean reinstall of #18b (format Data!). I suggest you have Kang TWRP 2.8.x.x. If not, it's needed firstly. Please simply follow the install instruction in post #1 carefully step by step. Download all zip.files ( ROM, pico Gapps and SuperSU) freshly from post #1 and flash them in one run through Kang TWRP. Good luck!
[Transformer TF300T Android Development] ddd3astra:
I tried out #18b and the same thing happened to me - not the frequent drop-and-reconnect I saw on #18 before, but a single, unrecoverable drop. The Wifi wouldn't turn back on at all until a reboot. Everything else seems to work (except for a permissions issue with a particular app) and it is very speedy. For now, I am headed back to my MM#29 backup.
[Transformer TF300T Android Development] warezhafid:
like others i'm having issues with wifi with 18b

i had no problems with the previous version

the wifi won't turn on until i reboot now
[Transformer TF300T Android Development] reyals1:
Workaround for the wifi drop: turn off wifi manually before letting the tablet go te sleep/closing the lid.

Then you can turn it back on manually after unlocking the tablet
[Transformer TF300T Android Development] gapecans:
#18b WiFi drop

I have never had a Wifi drop until 18b. This a hard drop.......Even a reboot will not bring it back up. Always perform a format data for very update. This is a first for me. Back to #18, all is great.

I had same problem with wifi on 18 B.. After instal this kernel problem is solved.. Thanks alote ;)
[Transformer TF300T Android Development] davidmorris:
I've just upgraded from MM 029, where I was getting frustrated by 'lag'; by which I mean apps took ages to open, Chrome ran slowly. Just very frustrating.

Today i downloaded 7.1.1/18b and it installed like a dream, and is running fast and clean. Superb.

EDIT: i should say I took care to do an advanced wipe before flashing, including internal storage; I had a clean microSD with just TWRP, and the ROM, picoGapps and SU + KAT; I formatted /data and changed back to F2FS

I'll be donating again.

Should I need to flash this revised kernel referred to above(post #632), how do i do it as a relative noob? Thanks
[Transformer TF300T Android Development] ddd3astra:
So far, so good. I went back to my #18b backup and installed the new kernel over top of it. So far I have had no Wifi drops. Thanks!
[Transformer TF300T Android Development] Samsura:
Allways fun to take out this old tf300 and install the latest katkiss version.

You are doing a great job on this, making the tablet still usable.

But if you ever get tired of this tablet, the Asus S3 Z500M is waiting for a developer :D
[Transformer TF300T Android Development] henk-jan:
Timduru, you're a great developer with excellent support . Big thanks for all your efforts.

Unfortunately I have to leave this threat because the tablet doesn't charge anymore. First the docking station and now the tablet itself is empty so it's "dead" End of a very nice instrument kept alive by you till now.

I really hope to see you elsewhere because you are the greatest of all the developers I've 'seen' at XDA.

By (snif) ;)
[Transformer TF300T Android Development] jcp2:
Is this only for the tf300 or do we need it for the tf700 as well?

[Transformer TF300T Android Development] Iceman_jkh:
Did you ever solve this issue?

I've got the same problem.

Tablet is unlocked and I've tried both KANG TWRP 2.8.7.2 and the latest TWRP 3.0.2-0 and both cause boot the tablet to stay stuck at the ASUS logo after flashing KatKiss.

Is there any way to view the output log (via adb) as it boots up, so I can report back here?

One thing I noticed, the little blue progress bar that appears the first time after installing KatKiss, goes from 0%-100% in 0.5 seconds. I'm guessing this is because something has failed rather than it installing very quickly.
[Transformer TF300T Android Development] yannmrt:
Not yet, still with the same problem.

I Didn't try to get any log.

The blue progress line it is something normal if I remember well, like kernel install or something like that.

If never you find the problem please share.

Thanks
[Transformer TF300T Android Development] doldi:
[MENTION=2829605]Iceman_jkh[/MENTION] and yannmrt

have a look to #631 ... i had the same problem, this steps and only with a new flashing of twrp_tf300t_kang_2.8.7.2.img is the solution.

boot after flash the old blob 4.2ver and install after reboot #018b Nutella ;)
[Transformer TF300T Android Development] mloc33:
At first, flash of 018b, my wifi was acting up, but since turn is been fine

My question isn't really rom related, I'm trying to upgrade my current twrp 2.8.1.0 to the latest.

I'm using Rashr, but when it tries to flash the latest twrp, I get this...

I don't have a laptop /PC.
[Transformer TF300T Android Development] ebonit:
Please note, "MM 6.0.1" and "N 7.1.1" require Kang TWRP 2.8.7.2@AREA51 (https://xdaforums.com/transformer-tf300t/development/recovery-twrp-t3046479).

Kang TWRP is available as *.img file that you may simply flash by your current TWRP! :cowboy:
[Transformer TF300T Android Development] mloc33:
Thank you, I'm so far out of the loop when it comes to flashing, I used to know what to do years ago.

I don't see the option to flash an img in my twrp.

I've Tried Rashr app and I'm getting the same error...
[Transformer TF300T Android Development] ebonit:
If my memory serves me right TWRP 2.8.1.0 should be able to flash *zip files and *.img files as well. Please open the main page of your current TWRP and then push the install button. A new window opens where you can select storage and sort files by name. There is also a button which may show "Install Zip". If you push that button it changes to "Install Image". That's it's what you need.

Now you can select the storage as ext_sdcard and there "twrp_tf300t_kang_2.8.7.2.img"
[Transformer TF300T Android Development] mloc33:
I don't see the option, I select storage and only see internal and external, nothing about img.
[Transformer TF300T Android Development] ebonit:
There are 3 screenshots that will give you the answer. The button "Install Image" shows you the zip files on your ext_sdcard. When push the button it changes to "Install Zip" and shows you the img files on your ext_sdcard.
[Transformer TF300T Android Development] mloc33:
My twrp must be an older version without the ability to flash img.

I'm looking for a flashable zip for KANG TWRP 2.8.7.2, is there such a thing?
[Transformer TF300T Android Development] ebonit:
I found one in my archive. Here we go:
[Transformer TF300T Android Development] mloc33:
You are the man, thank you very much for your help and advice.

I'll flash this here in a few and let you know.

All done, took about 4 minutes, thank you once again.

Should I just stay on this version of TWRP, it is this the latest?
[Transformer TF300T Android Development] ebonit:
Yes you should stay on this version, if you want to use one of KatKiss Rom! There is no need to use TWRP 3.0.
[Transformer TF300T Android Development] Iceman_jkh:
Thanks for the suggestion. I tried it, but didn't have success.

Can you post the exact recovery blob that you used please. I've tried about 5 (KANG, 3.0.2, 2.872-jb, etc.) and all fail to work for various reasons.

One thing I noticed was that none of the recoveries actually worked 100%. Most of them could not reboot themselves into recovery (even via adb). I think this might by why the install fails (and it's not actually KatKiss' fault at all).

The only recovery that I've been able to get to reboot back into recovery properly is: https://xdaforums.com/showthread.php?t=2617298, however it doesnt support convert to f2fs. If I try convert /data manually (following these 2 posts: https://xdaforums.com/xperia-s/s-development/tutorial-migrate-filesystem-to-f2fs-ext4-t3004755 and then https://xdaforums.com/showpost.php?p=63174760&postcount=615), I can't get it to recognise the f2fs... therefore I cannot install KatKiss. When trying to flash the KatKiss zip onto /data as an EXT4, it says:

ApplyParsedPerms: lsetfilecon of .system/lost+found t u:object_r:system_file:s0 failed: Operation not supported on transpo...
set_metadata_recursive: some changes failed
E:Error executing binary updated in zip 'sdcard/TWRP/KatKiss7.1..18b.zip'

Updating partition details.

Just for anyone else reading this: The reason I'm having trouble (I think) is due to having a TF300TL and the recovery doesn't quite work the same as the TF300T.

If anyone's got a TF300TL recovery that works fine and has convert-to-f2fs, please share it.

[Transformer TF300T Android Development] timduru:
New Version #018c

New rom version available: KatKiss-7.1_TF300T_018c.zip

That should take care of the "wifi not coming back after sleep unless you reboot issue".

if you don't have the issue, it's not needed to update to this version.

This the same than V018b + flashing KatKernel #045, so if you already did that it's not required to flash this version either.

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.

[Transformer TF300T Android Development] ddd3astra:
I still have been working well with the the #18b+kernel update and I haven't had those Wifi drops so far. I did notice a presumably unrelated problem. There are a few apps - like Quadrant (Standard Edition) - that are having problems connecting to the network. I think that it may be a permissions issue. I don't remember having the same problems on previous versions of Nougat. Does anyone know of any permissions changes in recent Nougat updates? I haven't found a found a permission switch to flip on that fixes it.
[Transformer TF300T Android Development] residentorca:
I believe my TF300T must be from a batch with laggier hardware. There is much less lag than ever running your v.18. it's really a noticeable performance improvement. Thanks for taking time to address the issue which has been afflicting some of our tablets. Your work is superb!

First of all, many thanks for your efforts to make the Rom furthermore smoothly!

I flashed version 18b plus Kernel as a clean install. Format /data run well without any issue. The performance I have gotten finally is unbelievable. Great!

After that I have checked whether all your usual tips in post #615 are realized on the tablet or not. They are! Compared with your video the tablet shows the same convincing performance as shown there. Thanks for that all.

All the best to you,

Really, nobody knows how to do this ?
[MENTION=3951330]timduru[/MENTION], is it something that need to be compiles in kernel ?

Thanks

You can find the .config used for the kernel there: https://github.com/timduru/tf300t-katkernel/blob/dev-tf300t/arch/arm/configs/katkernel_defconfig

CONFIG_USB_SERIAL & CONFIG_USB_SERIAL_GENERIC are activated,

Slow WLAN?!?

ROM: KatKiss-7.1.1_018c

May be I have a WLAN performance issue:

What I did: I installed the speedtest.net app on the tablet and did the test. Result: Download 10 Mbps, Upload 10 Mbps. I did the test several times with the same results! With a Nexus 5x and another Windows notebook I get for the download 50 Mbps and for the Upload 10 Mbps in the same WLAN network.

Can anybody else confirm this behaviour?
[Transformer TF300T Android Development] ebonit:
Regarding to Bradley Mitchell from lifewire.com depends the speed of a Wi-Fi wireless network connection on several factors.

"Each Wi-Fi standard is rated according to its maximum theoretical network bandwidth:

802.11b offered up to 11 megabits per second (Mbps)

802.11a and 802.11g offer up to 54 Mbps

802.11n offers up to 300 Mbps

802.11ac offers up to 1 Gbps (1000 Mbps)

The performance of Wi-Fi networks practically never approach these theoretical maximums. 802.11b networks, for example, generally operate no faster than about 50 percent of theoretical peak, around 5.5 Mbps. Likewise, 802.11a and 802.11g networks generally run no faster than 20 Mbps. And even though 802.11n rates at 300 Mbps compared to wired Fast Ethernet at 100 Mbps, the Ethernet connection can often outperform 802.11n in real world usage."

BTW, I don't believe in any speed test result. However if your results are true, you may be satisfied with them. :cowboy:
