Not without a lot of work. I believe that Katkiss 5 was the last that was compatible. Beanstalk 4.4 is the last ROM that was purposely built for the ME301
[Transformer TF300T Android Development] LupusInvictus:
Hi guys,

I just installed #34

Did a clean install and followed the instructions to the letter. No problems installing

But now I can't see my local wifi network in the list.

I see a number of networks, like my neighbours, but not my own.

Btw I have a Netgear R7800.

Any suggestions ?
[Transformer TF300T Android Development] LupusInvictus:
Okay, just found out what the problem was.

Channel setting on the router was on auto and for some reason, when I changed it to channel 10 and all of a sudden showed up on the wifinetworklist.

Anyone know the reason why ?

Never had to change it with katkiss marshmellow.
[Transformer TF300T Android Development] yuraterm:
This ROM cannot see WiFi channel 13, any other works fine.
[Transformer TF300T Android Development] Apeman00:
I tried to install. I am by no means an expert on any of this. But when mine boots all it does is vibrate and then reboots.

Big Thanks!

Big thank you [MENTION=3951330]timduru[/MENTION] for the security maintenance updates. Worth restating: My original Jelly Bean ROm'ed tablet had Alzheimer's, and was destined to be tossed away. Fun Fact: Ronald Reagan, the 40th president of the United States, loved Jelly Beans, and also left office with dementia. Could there be a connection? :D

KatKiss problems

Hello,

veteran TF300T KatKiss user here! I really have gotten to like the TF300T. Thank you very much for all the support over the years, dev.

2 issues on 2 devices still are present with V34 (and most likely will be with V35, too)

- Is sometimes getting really slow after a while of use, so that even the touch display inputs are not responding in time, restart usually helps (remark: using Xposed framework + XprivacyLua)

- (citation) "This ROM cannot see WiFi channel 13" ...and channel 12 as well, I might add.

- very high battery drain

I could even send one tablet (or even both) to you for you to check, if you will send them back to me afterwards ;)

Cheers.
[Transformer TF300T Android Development] pe1dnn:
I think this is by design. Channels 12 and 13 are not legal everywhere, channels 1 thru 11 are. I have more devices like that. I think the driver used is tailored for the international market, so 12 and 13 will not be available.

One thing you may have to consider after all these years is battery going end of live. Lithium batteries have a limited live span after all. Other than that your may have an app that causes the drain. If you check battery usage you may see what uses the most power. If it is system or screen than it is just the battery capacity which is not what it used to be any more.

Tim does his best to keep this tablet alive software wise. And quite successfully I might add. ASUS has given up long ago and abandoned their product (Shame on ASUS, I also have a Medion tablet and already got more updates than ASUS ever did). But slowly the tablet lived out its useful life when batteries start failing and apps get so power and memory hungry that the tabled will not perform any more. For example I switched to manual updates on the play store long ago so I will be in control when download takes place. When is does it will make the tablet slow so I want to do the download when I do not need it. Also no 5 GHz WiFi etc. But since it has been a good number of years in service, this tablet has been proven to be excellent value for money, with the great help of the independent ROM makers, most notably Tim.
[Transformer TF300T Android Development] lintrek:
I know, but it is dependant on the wifi gateway, so we should be fine. Channel 13 is the only channel that is not affected by the microwave oven btw - here at least.

No, I believe the 300's battery is top-notch, and shortly before flashing V34 it seemed as good as new - I am not kidding.

I know he does, but instead of solely uploading Youtube videos of his fast KatKiss tablet, he could consider what users are complaining about from V20(?) or so onwards. I could simply send him mine(s), no need to experiment here. He could safe himself a lot of time. If abandoning Play services etc. was the way to go, he would have told us long before. It seems to me there might be some memory leak maybe?
[Transformer TF300T Android Development] pe1dnn:
Microwave should be around 2.45 GHz which is channel 9, although these microwave oscillators are free running, not exact and wander around. But if it affects the lower channels then it must be a bit out of alignment. It may also not be as effective any more as 2.45 GHz is rather specific since it agitates water molecules; when off frequency it may not work as efficient doing so. I never had problems with the Wifi connection when the microwave was in use. But they should be properly shielded too, if it leaks too much RF then it is also not healthy. Lucky enough it is only used for small periods at the time anyway.

Maybe there is some hidden setting or what to enable these higher two channels. I usually keep away from channel 12 and 13 because it is not supported by all equipment.

I don think Tim did any major design changes in the last 20 or so versions. Just merging the security fixes into it. Maybe you could try to completely wipe it, go back to ASUS stock and then re-apply KatKiss Nougatella #35. Over time there might be a filesystem corruption which is not noticed in functionality but will send something astray which then keeps the processor busy. A fresh restart helped a lot of people to combat weird and explainable problems.

One other thing which can cause this is the WiFi infrastructure, especially the WPA key expiration and renewal. Set the lease time/key expiration time on your access point to the maximum amount of time, infinite if possible.

Other than that I can not help you. In the last 10 or so versions I never noticed any significant behavior change. Well maybe something actually, RAM usage causing my background image to crash. I just deleted those all and just use no background (i.e. black). Apps tend get more memory hungry over time and the TF300 does not have a lot of RAM with respect to today's standards.
[Transformer TF300T Android Development] diordnAMRZAR:
my 2 bits

So you ought to try out #35 to see if the battery life is what you expect. As for anyone who wants to complain, they can always roll up their sleeves and do the coding themselves. Remember too that [MENTION=3951330]timduru[/MENTION] does this without warranty or copensation, and does not win his bread and butter coding up a ROM for the TF300 and friends. Like all of us he needs to earn a living and feed himself and maybe his family. This is not a subscription service where we are to dictate how things need to be. [MENTION=3951330]timduru[/MENTION] gets it done just good enough for me, and I did throw a little money his way once upon a time ago, and expected nothing in return. His project is worth supporting, but he does this at his pleasure and conviencence.

We all ought to consider these facts before we say "how things should be."
[Transformer TF300T Android Development] lintrek:
According to some experts'(?) measurements and some implications thereof, microwave ovens tend to interfere with all channels. Luckily it always worked with channel 13. I have tried two HQ microwave ovens, they are unlikely to be all damaged.

That sound somehow occult to me. Are you really sure?

I cannot follow you here either, but I am not really knowledgeable in that particular area.

Yes! Same here! It seems to be a bug.

I am aware of the courtesy nature of free software projects. I am not complaining. We all are hobbyists in that sense. I could just get another device etc. I am merely trying to help. I have skimmed through all the posts and there seems to be a problem with performance issues just like mine starting from V20ish. I have two affected devices here, he can have them for analysis if he wants to. :)

---------- Post added at 08:22 PM ---------- Previous post was at 07:34 PM ----------

Those are some posts that clearly relate to my problem. My devices are often completely unusable because of performance issues - unless one wants to wait for hours to get stuff done.

There clearly is some issue there, maybe it is not an explicit bug in KatKiss OS but rather indicates that it is time for a feature change with the presets for the old 300s. Tim has already contemplated taking action against play services slowing devices down. Maybe that is the way to go? Anyhow, if someone happens to have found the magic answer, just let me know.
[Transformer TF300T Android Development] ebonit:
Thanks, I agree with you absolutely. There is no reason to complain about performance issues in general. :cowboy:

To my opinion it's also important from time to time to read carefully Tim's advises "Usual tips and what I do myself" in post #615: https://xdaforums.com/showpost.php?p=71094836&postcount=615.

And the features [MENTION=3951330]timduru[/MENTION] incorporated into ROM, like: ability to control the cpu clock speed to 1700, and governor choice, although these elements are actually just linux kernel features, but he did bring them the the Settings page. And the ability to allocate some ram for swap space. Couldn't do these two useful things with a stock JB ROM. My TF300 never ran better than how it does now with KK. Battery is solid, still charges full and fast, and has no appreciable sign of wearing out. I am amazed at this fact, given the hardware's age. I don't load up every app under the play store. Casual browsing -- TV listings, and other quick look-ups, Breaking news. It still streams youtube very well over my internet link. Some websites are just miserable to browse, but that's also true of my Samsing S5 phone -- largely the same websites too.

So has anyone here actually given #35 a test drive: Complainers and fans alike?

Do not feel the need for the change but for any security updates so ....that day will come sooner rather than later, but how about you [MENTION=9620553]lintrek[/MENTION] ? Did you even try #35 and if so what do you have to report?

There is just one problem left: the tablet is for my parents and they don't see that well. the battery information is super small. I would like a widget, but non is working with the docks battery. tried like 4 different ones. also many links to the playstore are broken.

any link to a working dual battery widget?

PS: key mapping for the dock does not really work for German. its goes always back to english after a restart. only solution is to use system default....

Enable off-mode-charge

How Can I enable off mode charge?

I would like, when my tablet is turned off, plug in the charger and stay off.

Thank
[Transformer TF300T Android Development] Catscratch:
I don't think its possible.
[Transformer TF300T Android Development] Luca84luca:
With version 6 it worked.

I read about some command like

fastboot oem off-mode-charge enable

But it does not work
[Transformer TF300T Android Development] ebonit:
:confused:

I think there is no difference. The device is always able to be charged in both mode off and on. The led on the on/off button must be on.

BTW you need the original Asus 15V/18W charger. Are you sure you have the right one?
[Transformer TF300T Android Development] Luca84luca:
I have original charger.

If I turn off the tablet and then, I plug in the charger, the tablet power on automatically.

I would like the tablet stay off when I plug in the charger.
[Transformer TF300T Android Development] RudeboyXL:
Either plug in the charger first and turn off the device (It will stay off and charge)

or

let the battery go completely flat and plug it in, It will not startup automatically (Not recommended to drain battery flat though)

If the battery has at least 2% to 5% charge, it will always boot up when you plug the charger in. just wait for it to boot then shut it down.
[Transformer TF300T Android Development] Luca84luca:
I want to chage settings in order to be able to plug in che charge when the tablet is off and stay off.

It was possible with Android 6 (Timduru version) so I would like the same with Android 7 (Timduru Version).
[Transformer TF300T Android Development] RudeboyXL:
Are you sure it was present in in the 6.0 version? i don't think it was, it's not a ROM controlled feature, its' a hardware feature. How would the software be able to change this behaviour if the device is powered off?
[Transformer TF300T Android Development] lintrek:

Whilst I agree Google Apps are a hog

Many peoples favourite apps have been purchased through Google Play and they only function due to google services to begin with (not just the purchase licence, but actual features require google play services), you are left with a limited selection of alternative apps that will work without Google services.
[Transformer TF300T Android Development] bigsatan:
You can use microg instead
[Transformer TF300T Android Development] RudeboyXL:
Isn't that just gonna run the services that are apparently slowing down this tablet? Doesn't matter that the name says "Micro", the services require the same resources to perform the same job.

Have you tested MicroG with this tablet?
[Transformer TF300T Android Development] gc2712:
I have and its much faster - not just from day one but after using for some time. Google apps is a hog. Period. Even pico Gapps is slow in comparison. I download Google apps i want through Yalp, but had to load Google Services to enable Free to Air video streaming apps. Don't sync with Google at all on this device. I use it as a media player and streaming stuff from the internet to my HDMI TV. I don't have any paid apps through the Play Store but Nanodroid installation will include Playstore with Microg.
[Transformer TF300T Android Development] teteu86:
Hello guys.

I took my TF300T out from the drawer and would like to install your ROM.

As per today, my device has AICP v3 (Kitkat v4.4.2).

I have already downloaded all required files (ROM + SuperSU + GApps).

I was only wondering whether flashing KANG TWRP is absolutely necessary or not, since my TF300T already has TWRP v2.6.3.1 installed.

Could I simply keep this TWRP and do the following: wipe everything > flash rom > flash supersu > flash gapps > wipe cache/dalvik > reboot ?
[Transformer TF300T Android Development] teteu86:
OK, just for the record, I decided to follow every step, including flashing KANG TWRP.

Just installed ROM by: flashing KANG TWRP (through fastboot) > full wipe > change file sys > flash rom > flash supersu > flash gapps > wipe cache/dalvik > reboot.

Make sure you use an external sd card, because I think by fully wiping, you lose these files in internal storage.

Concerning smoothness, no comparison: it runs much better now.

Good job!
[Transformer TF300T Android Development] teteu86:
Since yesterday, I was experiencing some lagging from time to time. I changed the governor to performance (I hadn't change I/O set as row).

This morning, I from the settings above in the thread history. Do these settings still apply, or have you found better ones?
[Transformer TF300T Android Development] ebonit:
No, not yet!

Please have a look at that post https://xdaforums.com/transformer-tf300t/development/rom-t3453702/post71094836#post71094836

You will find there a summarize of the "lag" topic. There are also a few very good advises by Timduru as "Usual tips and what I do myself". They make help you to check whether you have already done all the needed things like format /Data, change Data to F2S and keep the amount of apps as low as possible or not.

Many people often mix up wipes and formats. Please keep in mind "full wipe" is not format /Data through Kang TWRP. Kang TWRP does a deeper format that rewrites everything in the partition. No moldy leftovers after that.
[Transformer TF300T Android Development] Bozy25:
I can only agree. Had lag issues for a long time. After a reboot they were gone but came back within hours, basically after waking up from standby. Not fun to use. Yesterday I did a clean install and instead of Gapps I flashed nanodroid microG. All lags are gone although I reinstalled gmail, calendar, maps, YouTube. Just gave chrome a pass. Can only recommend this!
[Transformer TF300T Android Development] teteu86:
Could you share download link for this microG?

DId you download it from here? https://xdaforums.com/apps/magisk/module-nanomod-5-0-20170405-microg-t3584928
[Transformer TF300T Android Development] Bozy25:
Yes, that's the one I used.
[Transformer TF300T Android Development] teteu86:
You didn't have any trouble with Play Store? I am having RH error and can't get it to work even permission + force close and clearing data.
[Transformer TF300T Android Development] Bozy25:
No, playstore works fine, except that play protect does not work (complains about a timeout of app verification). Apart from that it works (installing apps). Did you format data?

Oh, and just in case, I used the stable version, not the beta:

https://downloads.nanolx.org/NanoDroid/Stable/NanoDroid-microG-20.6.20190126.zip
[Transformer TF300T Android Development] teteu86:
OK, I just flashed it again, and now it works.

Thanks anyway.
[Transformer TF300T Android Development] Bozy25:
Upon reflection, perhaps it's due to the microg settings? I enabled google device registration and safety net. Don't know if that matters. You can also do a self check in microg settings. Fingers crossed that you get it to work!

I am still amazed what a difference it makes - essentially turned my TF into a usable tablet again.
[Transformer TF300T Android Development] gc2712:
I'm really appreciating the comments about using microg here on this thread as i think its pretty much essential these days to keep our older tabs humming along. I've also moved across to microg on #35 and it stays faster than even a fresh install of pico gapps. PlayStore works for me too, but I don't have any paid apps.
[Transformer TF300T Android Development] vklimk:
Hi guys

It would be nice if somebody from you describe how to install microg for tf300t which runs KatKiss Nougatella #03x. Which steps it is necessary to perform and what are known issues?

PS. I have just run Signature Spoofing Checker on my tf300t which runs KatKiss Nougatella #032 and it shows that Signature Spoofing is enabled. It makes microg installation simplier :)

PS2. There is a fork of microg which contains additional improvements.
[Transformer TF300T Android Development] Bozy25:
As for installing it, it's just the same as a clean install (as in the OP) except that instead of flashing Gapps, you flash the nanodroid-microg package from here: https://downloads.nanolx.org/NanoDroid/Stable/

You set up the ROM as usual. You can do a self-check in microg settings (shows up in installed apps). If that looks good, you open play store and install your apps. I don't have paid apps either so can't tell you if that works.

It may be possible to dirty flash the microg package as it seems to be able to remove the google components (as explained here: https://gitlab.com/Nanolx/NanoDroid/blob/master/doc/GAppsRemoval.md) but I haven't tried that. Clean install looks safest to me.

Only issue I found is that play protect doesn't work so you might want to have some other security app installed.

P.S. A big thank you to timduru for the great work making it possible to keep this tablet alive!
[Transformer TF300T Android Development] gc2712:
I wonder whether its possible to have this info added to the OP as an option in the installation instructions?
[Transformer TF300T Android Development] bigsatan:
I use Yalp store with microg, instead of play store, and once connected with Google credentials paid apps can be installed
[Transformer TF300T Android Development] ebonit:
Start situation: The TF300T runs well without any issues on Nougatella version #35. There are 40 apps installed right now. No any complain about performance up to now. Just curious to check microG!

First of all I made a complete backup of the System and a backup additionally of Data only through Kang TWRP.

To prepare a clean install I run Format Data through Kang TWRP successfully. It took 34 minutes. Then I flashed Rom, microG and SUSuperuser in one run. Finally I restored the Data backup. Then I activated the Google account. That's it!

Now I can say everything runs well including the Play Store. The performance of the device has been improved noticeable. I think it's worth to install microG on the device. :good:
[Transformer TF300T Android Development] gc2712:
Can you clarify for me - Are you saying that you restored your backup /data which was based on Gapps, over your new /data which included microG? How does that work? :confused:
[Transformer TF300T Android Development] ebonit:
Yes, I can as good as it gets because I'm a simple user not a developer!

Nano Droid is independent of Google. That means microG is an independent Open-Source-Reimplantation of the Google Play Services. If you have it on your device, you will be free of Google apps that are preinstalled on Android devices generally by Google like System Base, Dialer Framework, Package Installer a.s.o. BTW, pico Gapps has 113 MB and contents all in all 7 apps.

Play Store however is included in microG. So you will be able to download what you need through Play Store ore somewhere else. But I wanted to have back my primary Data and restored it. After backup restore everything on my device looks familiar including the wallpaper.

3 Google Apps "Play Store", " Calendar Sync" and "Text-to-Speech" did remain. However the System of the Rom is clean. MicroG Team says no more monitor data that will be sent to Google and especially older devices can expect some performance and battery life improvements.
