First of all JB 4.2 isn't your tablets limit. Rather it is a good basis to install a custom rom like MM 6.0.1. Before you start make a backup of your tablet. Then, please, follow exactly Timduru's installation instruction in post 1. and make a clean flash. That means full wipe!

When successfully finished you will be surprised about the result. Your tablet has gotten a new life. Good luck!
[Transformer TF300T Android Development] muratbaizhanov:
Thank you for your enthusiasm. But I did that already 4 times. Seems like smth with my tablet is not right.
[Transformer TF300T Android Development] ebonit:
Unzipp Asus firmware 2 times. You should have a blob file now in the extracted folder. Put this blob file in your fastboot folder.

Open cmd and type: fastboot "-i 0x0B05 flash staging blob" without " ".

Let it run. It seems that nothing is happening for about 5 Minutes. The whole thing can take up to 20 Minutes, so just stay calm and wait till it’s finished.

Now you should be back to full Stock with Stock recovery. Then you should flash twrp_tf300t_kang_2.8.7.2.img firstly.
[Transformer TF300T Android Development] pe1dnn:
Maybe your tablet was on an older JB version and not the latest? Because that means also an older boot loader and that boot loader, you guessed it, causes bootloops with KatchMallow.

If you download the latest ROM from Asus (for your model of course) and follow this procedure: http://xdaforums.com/showthread.php?t=2528976 (this is for the TF300TG but you can use the same steps for any other TF300, only of course use a matching ROM) then you will have the latest ROM with the correct bootloader. Then try again, it is highly recommended because this ROM is so much better.

If you are missing ASUS apps, they are ported here: http://xdaforums.com/crossdevice-de...asus-zenfone5-apps-port-t3010941#post58926556
[Transformer TF300T Android Development] muratbaizhanov:

i did update the bootloader because the OP in KANG twrp requires the latest bootloader. and katkiss requires kang twrp =)

but anyways, thanks again. i'll leave the stock but solid rom

So far, love this rom. It has breathed life into my tablet again.

Install was a bit wonky. Came from stock 4.2.1. Installed TWRP and wiped per instructions and changed data to f2fs. No problems.

Flashed ver25, supersu and gapps. wiped and rebooted. Loaded up and went thru an abbreviated setup wizard. Connected to the wifi and then went to the play store and couldn't get things to download, just sat there. Did some reading and tried to update gapps, used one that caused play services to crash.

Saw it may be the gapps, wiped again and reinstalled using open gapps pico but used one after 3/20/16 and caused a boot loop.

Did a reinstall of the rom without a full wipe, just cache and dalvik, flashed supersu 2.5.2 beta and open gapps pico 2/28/16 - success.

Supersu updated properly after reboot, play store is downloading my apps, gmail works and all my apps are super fast compared to yesterday with 4.2.1. Seems really stable, my test is streaming directv and it's been rock solid, no buffering or dropping the stream.

I'll play with it more but for now, thanks for a great rom.

Update the xpose installer to 2.7 experimental and from it updated xhalo. I think this will do

hi, i would like to try it in my tf300tg . Can i use the same procedure & rom for TF300t in this guide? If something goes wrong, is it possible to reset it to its original OS(clean is ok, i have already my data backed up)? Thanks!
[Transformer TF300T Android Development] ebonit:
If you have a backup of your tablet's image by TWRP, there will be no problem to restore your system when something goes wrong. You may try it on your own risk.

As far as I know the rom itself runs well on TF300TG, but you will loose the "G"-ability. If you can forego it, you may try the rom. Please follow exactly the installation instructions in post 1.
[Transformer TF300T Android Development] stenonet:
No problem for "G" function , i dont use it at all. I use My phone's hotspot through Wi-Fi , when i am without Wi-Fi . Thanks i will give it a try.

Only a limited amount of adivce can resolve many of the issues reported here - yours will likely not be one which gets fixed by a thorough wipe and re-install of the stock firmware. All sarcasm aside, this is still a decent tablet and I am wondering what it might take for my device to finally bite the big one. I will probably have to resort to something similar and have fall into the toilet or drop it while skydiving. It keeps getting new life and won't succumb to the normal things life throws at it. A pretty decent run.

[Transformer TF300T Android Development] HungLu:
Hi all, recently upgraded my TF300T from stock to Lollipop, and then when I couldn't access my ExFAT SD card, exFAT USB and NTFS USB, so format /data, F2FS /data then install the current MM in this thread (v25). But it seems that MM doesn't see these devices neither. Ex Explorer get notify them but cannot access their content. The Setting didn't see them. No mount/un mount Dock USB nor Dock SD External. One more thing the MultiPicture Wallpaper app works better than Lollipop but sometimes lost when reboot or shutdown. That's all I found.

Timduru, I own you an apology. The NTFS works as expected. I plug another 160GB and 500GB, the system setting storage & USB shows the USB drive. EX Explorer get notify and it can access the content of the drive. I thing the first 500GB drive could have problem with the power supply. It's a Wi-Fi drive with its own battery. I thought that it won't need the power from the USB. So only exFAT doesn't work yet. Again sorry Thank Timduru for your hard work.

Note: I did reformat the 128GB microSDXC with Windows 10. I didn't have Linux

[Transformer TF300T Android Development] ebonit:
As far as I can remember a white line appeared sometimes. It was noticeable after rom change from stock 4.2 upwards. It can be repaired as follows advised by zaki0saad:

"Download Xposed installer. Activate and reboot, then download the GravityBox [JB] module.

Enable 'GravityBox > Display Tweaks > Dithered Holo Background' -- and then reboot again. This will remove all those issues you have seen with the white banding."

But you wrote from "white lines (plural!) combined with display flickering and something else". This might be caused by the touch screen or other hardware. Please have a look at http://xdaforums.com/showthread.php?t=2770420

No screen rotation

Is it just me or does auto rotation not function.?
[Transformer TF300T Android Development] Alagos:
For me it works to and from both short sides to the "regular" orientation with the Asus logo oriented the right way, but not if I want to turn the tablet upside down (very convenient sometimes since the charging port is on the bottom side). I used to have this problem on Lollipop too but it was fixed sometime. The app Rotation Manager used to fix this issue but not anymore on Marshmallow.
[Transformer TF300T Android Development] 1di9:
Mine too, since I passed from katkiss to katshmallow (clean install with data partition formatted in f2fs) I noticed it's very laggy expecially after wake up from stanby, and some apps are really slow in opening and working (email apps like k@mail or blue mail).

I'm running #025 after dirty flash over bulid #18, as governor I've set conservative and row, using Zen ui as launcher.....exactly the same as with lollipop but different behaviour..... ??

I recommend to use "interactive". If you want to save some battery, you can UC (min: 102 Mhz, max: 1.3 Ghz) and it runs smooth, too. :)
[Transformer TF300T Android Development] 1di9:
Thanks for suggestion, I'll try interactive governor. However I'm already underclocking, 300 mhz - 1 ghz max.

According to me, for battery saving should be better to decrease overvolting.....

Inviato dal mio TF300T utilizzando Tapatalk
[Transformer TF300T Android Development] pe1dnn:
I don know about your experience but for me battery saving like this never did much, when I look at the battery usage the screen is my number 1 power consumer and I already run it at a low brightness. So I keep my CPU to the stock 1500 MHz so it can deliver peek power when needed (could even do 1700 MHz on mine but stock is fine for me). Of course it helps a little but as long as the screen stays power hungry the increase in run time will not become very much higher. With that in mind I like my tablet to be responsive while it is working.

I'm using the stock governor (interactive), minimum (204 MHz) and maximum (1500 MHz) speed and cfq I/O scheduler (instead of row so I ticked "Set value on boot" on this one. No ZRAM, no idea if that speeds up anything.
[Transformer TF300T Android Development] Deeemon:
I came from stock to katshmallow.

Format/data done,f2fs not,i didn't know what it was so i didn't do anything.

Maybe 15 apps.

i think i set the "performance" governor,because it was laggy but it was still the same lag.Only more battery consuming.

Should i go back to stock?
[Transformer TF300T Android Development] ebonit:
Missing F2FS seems to be the problem!

First of all you must have Kang_TWRP 2.8.7.2@AREA51. Then format /data to F2FS by TWRP. Be careful /data only not either /cache or /system. After that make a clean installation like advised by Timduru in post #1 and your tablet will get a new life.
[Transformer TF300T Android Development] 1di9:
I agree with you, display is energy thirsty and there's nothing to do...because of this I prefer to save as much battery as I can setting a performance low profile, acting on governor or soc frequency and sheduler.

However, setting interactive governor effectively reduce some lag, thank for suggestion ?

I've been using this ROM for a few months now, and it's been mostly great but I did have some performance issues, which I was managing with governors and frequent reboots.

An app trashed my data partition causing a boot loop and so I formatted everything, reflashed to stock and then ran through the kk install process from scratch, only installing the apps that I use. I haven't enabled Google Now. Now everything has been silky smooth for over a week!

[Transformer TF300T Android Development] chrisautrey:
I kept the original format for my data and did not switch to F2FS, and did not change anything related to performance from your default settings.

I could not get any terminal to work without force closing so I could not pull logs. Can you add a working one back into the ROM like we had in Lollipop maybe?

My TF300 has been solid on all of your Lollipop builds and 030 is working great.

This sounds great. I have the KANG TWRP, i understand (i think heh) all these steps, but the h264/x264 errors scare me, as i use my TF300T as a Kodi 15.2 player mostly. All the movies and shows are x264 dts or DD 5.1.

Has anyone tried this on 007? I'd be coming off of z-pop 5.1.1 so i'd need to format data i am sure, and can find no info about Kodi running on 'Mallow 6.0.0 on any device. I need this to put me to sleep, it's my TV/PVR... Should i wait? Is this maybe a libstagefright problem?

Thanks for doing this, Tim... you are worlds beyond what i thought this device would do. I could care less about the rotation problem as really i use hangouts and Kodi 90% of the time. I read (off of xda) that *mkv watching junkies like me should keep ext4 on /data but 10 minutes an app? This is from ext4? Or did i missread? I'm a tad 'vaped' ill have to read all this again... but i would THINK that h264/x264 video player errors were looking for libstagefright.so and couldn't find or use it? XBMC (now Kodi) had to use an external player until they got HW acceleration working in XBMC (namely libstagefright) and since BS Player or MX Player worked with HW acceleration, and all three of those now work on 5.1.1 (on ext4) i am guessing it may be a kodi/Mallow 6.0.0 thing? Will ask my friend google as well. If anyone wants to test it, Kodi is free on Play (and awesome, if it works) uses UPnP or SMB etc protocols so all video data is NOT local. Yeah ima look there kodi.tv heh duh i am sure it is working on SOME 6.0.0 devices maybe they can shed some light.

Thanks again

F2FS Test

Well, I did the complete format change to F2FS, installed 007, and the optimizing apps problem has gone away. It definitely seems faster.
