Rom works good, but the TF300 is starting to show how old it is.. But great work!

Just wondering - why does it Optimize apps for about 30 minutes at every boot? this also kills the battery since cpu is working so hard on this..
[Transformer TF300T Android Development] DriftJos:
Format your data partition to f2fs and it is fixed, is my experience.
[Transformer TF300T Android Development] lollyjay:
Tru dat!
[Transformer TF300T Android Development] Samsura:
Thank you for the suggestion!

Do you know if there is anyway to do this without using TWRP?

TWRP has never worked on my device, and clockworkmod does not seem to support f2fs?

Tried TWRP again and installed the KANG version suggested in first post, but it's impossible to press anything when it looks like this:

Sorry for horrible image quality. My Note 4 is being repaired and my Nexus 4 camera is broken and just takes pictures like this.

Edit: actually managed to get it done while beeing "blind".

Wonder why TWRP has never worked on my device though.
[Transformer TF300T Android Development] giveen:
Is there any way to tell between dock battery and tablet battery?
[Transformer TF300T Android Development] Xipe_Totec:
Hello, i think i made a mistake.

Following your instruction i used the function format /data through TWRP via the button "format data" in the "wipe" section. It runned for more or less 10 mins then I believe it was stucked and I rebooted my device. Now, when I try to wipe or mount the /data TRWP says me it can't be mounted.

I am running again the format /data command. Am I doing right or i bricked my device?
[Transformer TF300T Android Development] walttheboss:
Never stop TWRP while its working. To change to f2fs you choose "repair or change filesystem". The format option will just reformat the drive to its existing system and not change it.

The format to f2fs the first time can't take up to 45 minutes. There's no progress bar so just wait.

If you can't Mount data then I am not sure the way forward. Others will answer.
[Transformer TF300T Android Development] Samsura:
Must say that F2FS made the tablet twice as responsive. Formatting data to f2fs should be part of the installation manual.

Exelent stuff.
[Transformer TF300T Android Development] Keshukas:
I heve don that to formating /data and then i rebooted my device before it's finished format

Then you can when in TRWP connect USB cable to pc and in terminal connect with "adb shell", then execute command mkfs.f2fs /dev/block/mmcbk0p8 after finish and rebooted I get no more errors
[Transformer TF300T Android Development] Xipe_Totec:
i have to say TWRP never worked fine in my asus device, while in my OPO works like a charm.

Anyway, i formatted again the /data partition and now i am runnin this new rom with f2fs.

I hope it works like the previous one ;)
[Transformer TF300T Android Development] Xipe_Totec:
I have to say just one think: terrific rom. Fast, stable and insanely smooth.

I just have only one question: everytime I connect the tablet to my pc I have to manually switch the USB mode from "only charge" to "mtp" to transfer file. Is there a way to make this choice permanent?

Great work [MENTION=3951330]timduru[/MENTION]
[Transformer TF300T Android Development] purple patch:
Hi, my Wi-Fi keeps disconnecting and reconnecting. Notice it during games like clash and boom beach. I have seen the talk about it, but not sure why I should have to change my Wi-Fi router settings when every other device is fine. Including the lollipop version of this rom. Can anyone explain the issue to me. Sorry if it's been answered but I do read entire thread and installed as per instructions.
[Transformer TF300T Android Development] UndisputedGuy:
Honestly find it surprising that formatting to F2FS can supposedly make such a radical difference. I find my tablet is pretty smooth anyway with this ROM.

Is it really worth doing? Can I just copy the /data files to an external device and move them back on to have things continue as normal? Lot of useful data there for me

It's nice to be important, but it's more important to be nice.
[Transformer TF300T Android Development] purple patch:
Def a difference for me. Close to double speed improvement. Just back up whatever you need. Was gonna buy new tablet, changed to f2FS, not buying new tablet now. Lol. Although if I can't sort Wi-Fi issues new tablet time haha.
[Transformer TF300T Android Development] dgcruzing:
Agree..do it.. F2FS will change how you view this tablet..

No WiFi issues for me on two of these I have it on..

Strange that some tablets are doing this..
[Transformer TF300T Android Development] shdware:
My thoughts...

On ext4 I noted that there was a delay especially when switching apps. Installing/uninstalling apps took longer, too. But in terms or regular operation, once things were running and loaded, no discernible improvement of significance is really there.

F2FS made switching between tasks very fast, as well as improving load times. I wouldn't say it's twice as fast, but I would say that it is a lot more comfortable to use with less waiting. How about a 30-50% improvement?

The only issue I noted was that if you had a forced reboot (it happened with a game I was playing) or if the battery runs out, you can have data corruption. The fix was easy - I had to uninstall and reinstall the corrupted apps. But that brings up the possibility of system corruption (happened once also). This happened with early builds to KatKiss 5.0 and hasn't happened since. There's a lot more stability. And the fix was simple: just dirty flash the ROM again, even with system corruption, and all of your files are there and everything is good.

I think it's worth it.
[Transformer TF300T Android Development] Rammv:
I had the bluetooth issue where it would cut out then in and so forth. Did a dirty flash over existing katsMallow all is good now.
[Transformer TF300T Android Development] shdware:
The Tegra3 does support Miracast, but drivers are not released; Miracast does not work with this ROM (or any ROMs for the TF300).

---------- Post added at 12:55 PM ---------- Previous post was at 12:09 PM ----------

Well, my kid broke my tablet, so all of my TF300 participation is gone. I wish you all the best of luck.

[MENTION=3951330]timduru[/MENTION], you are the most consistent Android developer whose ROMs I've used. I would love for you to do more development, but one person can only do so much!
[Transformer TF300T Android Development] Stephenhon:
+1

Just change to performance instead of ondemand can solve the problem. ^^
[Transformer TF300T Android Development] sergiolopezsan:
I wanted to know if this ROM is compatible with OPEN GAPPS.

On their webpage, they say that with 6.0 AOSP ROMs we need this

patch

:

So timduru, can you apply this patch in your ROM in order to make it better or is there something that doesn't let you (like for example f2fs [maybe])?:confused:

If it is not very difficult, could you do us this favour?:angel:

If someone else thinks like me, please, support my idea. :highfive:

Thank you.
[Transformer TF300T Android Development] timduru:
I've done that a few weeks ago already

https://github.com/timduru/platform-frameworks-base/commits/katkiss-6.0

So it will be in the next version, but that version is currently delayed by 6.0.1 headaches modifications that makes it not booting :\

Just use the gapps in the 1st post anyway, that's my advice.

Not sure why you'd want other gapps, it contains the minimal package,

and from there you can find everything else in the play store...
[Transformer TF300T Android Development] sergiolopezsan:
Ok, thank you and hope you can fix it.

I wanted to install open gapps package because with it, I can replace AOSP apps with Google apps, like calendar, webbrowser, etc. In addition, these apps would be installed in the internal memory (I don't know the exact name) and would use less storage. Correct me if I am wrong.
[Transformer TF300T Android Development] timduru:
Yes on the first install and flashing it will go into the /system partition

( just be careful of how much you try to fit in there, as the space is very limited)

But from your first gapps install, they will then update in /data and take twice the space.

So basically as they are available in playstore, I prefer to install once in /data myself if I need them.
[Transformer TF300T Android Development] pe1dnn:
Format clears all memory cells, checks them and finally writes a clean file system structure back. You interrupted half way and now mounting is impossible because there is no file system, only a partially cleaned disk partition.

It's like rebuilding your house, you bulldoze the ground clean and build a new house. Now the ground is partially bulldozed and your house is not there yet. And now you can't find the front door anymore.

To regain control, follow the steps in the following posting. When done you are back to stock and then try again. And don't interrupt the process. http://xdaforums.com/showthread.php?t=2528976

This is also the solution for other strange problems like the TWRP double screen problem which was reported before. With the described procedure the tablet will be in a known clean state and all subsequent steps should work unless the tablet has broken hardware.

Of course as always follow the provided steps, shortcuts by skipping steps often result in a bad end result, having to redo it without shortcuts in the end to fix it.
[Transformer TF300T Android Development] Xipe_Totec:
I simply formatted again the /data partition and then switched it to F2FS.

Now it works like a charm.

As another user said before, I was going to buy a new tablet but after trying the F2FS partition system, I am going to keep my TF300T.

Huge leap in terms of rom stability and quickness. I have to say I have no wifi issues at all. Everything works fine in my case.
[Transformer TF300T Android Development] Neccie:
Also having this issue but to me it looks like it's not continuously. When I wake the tab it's fine, as in game loads and wifi works. But after a short while after it reconnects so the game is dropping me out. After that it seems to be working fine untill I put the tab away.

Can't find the router settings you mention though. But like you my other devices (1+1 , G4 and TF700) all work fine on the same router.
[Transformer TF300T Android Development] purple patch:
Hi, I have fixed this issue. I tried dirty flash first, but got force closes from setup wizard. I then did a clean install again, exactly the same as first time I installed. (Rom then gapps then SU). Problem has gone away. No more disconnects after few days use. Changed no settings in my router.
[Transformer TF300T Android Development] JuraP:
Most probably you've flashed wrong recovery. Double check and flash right recovery via ADB commands Best one is the Kang version of TWRP [MENTION=5123642]lj50036[/MENTION] 's (thx, buddy! )
[Transformer TF300T Android Development] Samsura:
The one i am using now is the Kang version (from first post) that i flashed via ADB.

Have tried alot of different versions of TWRP while flashing alot of different roms since 2012.

TWRP have never been working. But clockworkmod has worked fine so that's what i have been using.

But some roms with "install scripts with options" has been glitchy aswell, even on clockworkmod.

[Transformer TF300T Android Development] JuraP:
And are you sure you are on the right bootloader? Mostly this split screen TWRP is caused by flashing TWRP onto older bootloader o ontor wrong device
[Transformer TF300T Android Development] Timur208:
I updated from v10, it stucks in boot, optimization apps. When I reboot tablet, it dont boot at all (stuks in asus logo and reboot after 10-15 s). Second wipe dalvic cache doesnt help, it stucks againe on 16 (or 36 in 2nd situation) of 87.
[Transformer TF300T Android Development] timduru:
Flash clean, follow instructions from the 1st post.

format /data f2fs

Be patient and do NOT force reboot when it's optimizing apps

Just wait.

[Transformer TF300T Android Development] pe1dnn:
I did the same, no problem at all. I do of course not have experience during normal use of this new ROM but booting and optimizing was the same as with v10 and no problem, it all appears to be fine right now.

Twrp is still buggy but it does not matter now that its done.

Pretty shure i have the latest bootloader, but is there an easy way to check?
[Transformer TF300T Android Development] lj50036:

The only problem I've come across is Youtube wanting to play back 720p at 60Hz which the hardware doesn't support, instead of 30Hz.
[Transformer TF300T Android Development] pe1dnn:
While you still have the old boot loader you may want to create the brick-save files first, that requires an old bootloader because otherwise you need to install a patched boot loader later. How to create it is in the stickies of the TF300T Android Development forum.

Having these brick save files you can always recover, even if you corrupt the bootloader. Highly recommended.

I'm back to Katshmallow #11 and everything is great so far - even Vim Touch installs correctly. Thanks again, Tim, for the awesome work and for keeping our tablets going when so many others have fallen by the wayside. It may sound like we are complaining from time-to-time, but we really appreciate all that you do!
[Transformer TF300T Android Development] henk-jan:
After new update I formatted data again and then F2FS, now everything seems fine. Probably bad format data as reason for the problems?

With #11 everything seems ok. The tablet finds the SD and mini SD without any problems.
[Transformer TF300T Android Development] Stephenhon:
I fixed the issue by changing the governor from ondemand to performance.
[Transformer TF300T Android Development] Samsura:
Thank you for the tip.

As i understand you mean that i should use NVFlash to make a brickproof backup?

I tried yesterday to just flash the new bootloader in TWRP, but i guess that's not how it's done since it just got errors :P
[Transformer TF300T Android Development] henk-jan:
After one day experience with #11 I can say: it's smooth as butter, no lags anymore, fast as h*ll. Probably the wrong formatting /data caused the lagging.

Great job, big :good:
[Transformer TF300T Android Development] pe1dnn:
Yes, http://xdaforums.com/showthread.php?t=1894867 and when on AndroidRoot look under guides. Updating the boot loader is risky, don't mess with it otherwise you get a brick. Go back to stock (link posted some days ago), then manually update to the latest ASUS ROM. Google for "TF300 manual update", this will upgrade the boot loader during the process. When done go ahead with KatshMallow as before. My final post about this to avoid littering the KatshMallow thread with off-topic content, there is a lot about it already on XDA and other forums.

Exactly same issue here after 10->11 update. I did wipe cache and dalvik but did not a data wipe. Is that update requiring a data wipe? Actually the only issue after restoring all apps with TitaniumBackup after a full wipe is re-arranging the desktop icons, I did not find a solution for that).

So full wipe required? I thought minor changes from 6.0.* could work without...
[Transformer TF300T Android Development] compact_wisdom:
They could, yes... but if they do not, you have to go with a full wipe.
[Transformer TF300T Android Development] timduru:
It could , but most importantly:

did you flash the 3 zips when doing the update : rom + supersu + GAPPS ?

Usually If you don't flash gapps and reboot to the rom it'll cause the issue you're mentionning.

You need to flash them everytime.
[Transformer TF300T Android Development] walttheboss:
Maybe a hardware issue. Too much heat causes an electrical contact to open. Then it cools and closes again. I would try to set up an unencrypted WiFi ssid and try that. There's a mixed setting in most routers allowing older devices to connect on wpa and automatically use wpa2 for capable devices. Try that.

Check WiFi sleep setting and set to always on.

Try perfectly clean flash then.

You could pop open your tab and see if the WiFi chip is removable? Then get a new one to match.

I found just one bug and I have some questions:

bug: settings crashes also to me when going to settings -> more in "wireless and networks". I did a clean install, formatting data and wiping evwrything.

questions:

1) my external sd has a strange name in file explorer, using es the label is "3463-3730”, is that normal?

2) I can't find differences in user interface -> mode -> between phablet UI, phablet UI no navigation bar, immersive mode navigation bar

3) how ro remove google bar from homepage?

4) what is the 4th icon in navigation bar, the one with two squares? can't understand how use it.

How fast is this Rom?

I find my motivation to upgrade/change Roms these days is the search for lag free performance in normal use. I currently run my TF300T on Zombie-Pop 5.1.1 and achieve Quadrant scores of approximately 6500.

Would some kind soul be willing to run the free version of Quadrant from the Play Store on this Rom and report the result as I would certainly consider installing it if performance is improved even further over my existing installation.

Many thanks.
[Transformer TF300T Android Development] DoughMucker:
6803
[Transformer TF300T Android Development] gc2712:
Still speedy then. (I was concerned an upgrade to android 6 would be slower as they add more "features" to the OS) At least no slower than 5.1.1. I'll give it a go then. Many thanks for the Quadrant result.
[Transformer TF300T Android Development] DoughMucker:
You're welcome. F2FS gets rid of even more of the lag. I can only imagine what an inverted system would do to it. I have that on my TF101 with Tim's 5.1.1 KatKiss and it is great. I'm not sure I'd want to go to KatshMallow without F2FS or the inverted system.
[Transformer TF300T Android Development] gc2712:
Been using F2FS for a while now. :D Sometimes wonder though whether ext4 plus regular manual TRIM commande in terminal isn't better. (I've tried both options). At least when it gets laggy, running TRIM on Ext4 does speed things up again for a while, whereas if F2FS gets laggy (and it does) there is nothing I can do.
