[Transformer TF300T Android Development] Catscratch:
Hi guys.

Thanks for this Rom so far. Everything seems to work good except wifi. I got random disconnects which is littlebit annoying during online gaming.

Is this a known problem?
[Transformer TF300T Android Development] mumblyjoe55:
Cheers Tim, new version runs smoothly :)

Also thanks to those who tried to help with my GPS issue. After a bit more exploring saw that Wifi scanning was off and now can get a fix with external GPS. However the internal unit is still toast and at best can detect two satelites but with no fix. I pulled apart the tablet today to inspect the mainboard and antenna. No corrosion or obvious damage. Curiously, my Wifi works brilliantly so unlikely there is a problem with the antenna.

My thoughts is that this is either hardware (i.e. motherboard or GPS chip damage) or firmware. Before installing Nougatella I did an NVflash backup using the recommended WW 20130416 firmware however I am aware that their are newer version of the firmware available. I am tempted to see if this makes any difference.

Which firmware version did you all install prior to running Nougatella?
[Transformer TF300T Android Development] shanewhittington:
Hi Timduru. I just want to thank you for your work on this. it has breathed new life into my little Transformer. I also sent you a small donation last night as a further token of my gratitude. Keep up the outstanding work

Also, does the Kat toolkit work with this version? I got a lot of use out of the audio boosting feature
[Transformer TF300T Android Development] timduru:
Not for the moment.

I made a new version of the kat app for nougat but it'll also require the next rom version to work (V011)

So soon :)
[Transformer TF300T Android Development] rena_:
Thank you very much for including the signature faking patch [MENTION=3951330]timduru[/MENTION] !!!

Now i got the blankstore running and was able to log into playstore and update the navigation app, which is working now.

For other apps there are still problems because i seem to see free or demo apps only.

But thats not a katkiss problem...
[Transformer TF300T Android Development] db77:
Yes, because I have already a recovery TWRP 2.4.4.0 and Energy ROM.

I can boot in Recovery or Bootloader

When I start the TF300T a message say "Device is unlocked"

But I don't know the number of the Bootloader and how to know that :(
[Transformer TF300T Android Development] gc2712:
I just tried booting my TF300t into the bootloader and connected it to my PC's USB port. Typed 'fastboot devices" into a terminal (I'm using Linux Mint 20.2) and it immediately came back with device ID. So If you have booted into the bootloader and are unable to detect fastboot device then I would say its most likely a driver issue. Are you using Windows?

It's late here. I'm going offline in a few minutes.
[Transformer TF300T Android Development] db77:
Yes I'm a windows user

And "fastboot devices" say nothing. But "adb devices -l" find my TF300T if my TF300T is started with android. When in Bootloader mode, nothing
[Transformer TF300T Android Development] gc2712:
Maybe have a look at this thread and see if it helps.

Hello,

I've done and now I have this :

My device is detected (my TF300T is in bootloader mode) but the flash don't start. Nothing on screens (both TF300T and PC). I'm waiting for a long time but nothing

EDIT :

After a second try, It seems to be GOOD ! Thanks very much !!!

NEW EDIT :

My device, when rebooting in recovery mode, has two screen (two recovery on one screen), so I think I don't have a good bootloader....

So, now, I have to search how change this bootloader to have the good for this TWRP
[Transformer TF300T Android Development] gc2712:
Glad it's working for you! 😁

I can't selected option because screen is flashing and 2 parts, one at bottom, one at top, so impossible to select. And I don't see my SDCard also. So it's dead for the moment...

with TWRP 3.4.0.0, all works fine and I have installed KaKiss. Many thanks

Hello,

Is there any way to unlock a bootloader of TF300T? The V7/V8 official versions don't work. I think ASUS stopped the bootloader unlocking service for this model.
[Transformer TF300T Android Development] A.Petrov:
I have troubles with WiFi connection over EAP-TLS security.

My network has a number divices (Win/Linux/Android 10&11/iOS) with success setup on EAP TLS. But TF201 with this ROM - connection newer establised. Same if I use dedicated certificate for TF201 or if I use credentials taken from the device with success connection.

Any one has success setup with this type of security for WiFi?

Thanks.

PS.

omg. I think I post the question in a wrong thread (TF300 instead TF201).
[Transformer TF300T Android Development] A.Petrov:
Perhaps this question is meaningless. This because of complete broken wifi connectivity with EAP/TLS security in a history frame of Android releases from august 2017 of 7.1.1 release til release of 8.1:

https://issuetracker.google.com/issues/64928420

So, due to inactivity of development, conclusion is - wifi with EAP/TLS security in all kind of TF devices is unusable completely.

I installed katkiss 7.1 on my asus tf300t tablet according to the posted instructions.After booting up I tried to install apps from Google Play. Here happens a strange thing, the program is downloaded sometimes 2 -3 times, and after a while, the message that the application has not been installed appears. When trying to install the program from external SD memory is the same, the program can not be installed.In the settings is unchecked installation from an unknown source.In the Google Play application I have cleared the memory Cashe.

Previously installed Android 4.4 and there were no problems with installing programs.

Can anyone help me.

Hi, Am bit rusty with android flashing, here is my question.

Currently running KatKis 027 6.0.1 (twrp recovery from that time)

Want to upgrade to the latest available 7.1.2 - and NOT using gaps.

Assuming i need to:

-download rom

-wipe (i have noting to lose)

-flash from twrp

-flash super SU from twrp

-keep it on charger for first run and first few hours

thanks in advance
[Transformer TF300T Android Development] gc2712:
You may also have to format /data F2FS. Just read the instructions on the original post for first time flash. It's all pretty clear.
[Transformer TF300T Android Development] gferen:

Just noticed that video thumbnails show greenish lines.

The video plays good.
[Transformer TF300T Android Development] timduru:
Yeah that's the downside of having fixed the hardware video codecs,

greenish thumbs as there's something they don't like in extracting the thumbnails for some reason,

But now videos plays gpu accelerated, 720p60, 1080 + adaptive playback fixed so netflix is also happy in using the hw codecs ;)

Video are much faster and fully smooth now.

I'd say for the moment it's better like that at the downside of greenish thumbs :)
[Transformer TF300T Android Development] Matchless 2015:
Its not an issue for me at all, I can definitely live with that!

Thanks for your hard work!!

Erratic battery stats

Just installed #012 today after full wipe and formatting /system ,/data and /cache. (the latter two are F2FS), pico Gapps for 7.1 and SuperSu from links in op, and reinstalling all apps from Google Play. Noticed that battery levels were constant despite use and "battery usage data isn't available" message in battery stats settings. Cleared cache again and turned off TF300 for a while. Restarted Tablet and battery icons and percentage levels seemed to be working. But later seemed to freeze again with the usage data error again in battery stats. That is, seems to be erratic.

The only other issue I've noticed is that the default virtual keyboard swipe function does not work at all. Had to install Google keyboard from playstore.

Otherwise, everything seems to be working very smoothly. My only hope it that audio recording can be fixed sometime as it worked in earlier versions. But very grateful for the tireless efforts of timduru in keeping this and my tf700 usable.
[Transformer TF300T Android Development] Matchless 2015:
I am not sure if /cache should be changed to f2fs, according to Timdurus guide it is only /data.
[Transformer TF300T Android Development] timduru:
hmm, I don't have battery stats issues here, if it happens again grab a logcat + kmsg + top

Hmm, that's actually interesting, do you remember which version it was working fine ?
[Transformer TF300T Android Development] fred_bra:
Two questions:

1- How does this compare to the Marshmallow version, in terms of performance and battery life?

2- I took my TF300T with KatKiss Marshmallow to a trip last week, and the airline has an APP for the in flight entertainement (no screen on seats). But I could not use the APP because it detects the device is rooted. Is there a way to conceal from the Airline APP the device ir rooted?

Thanks.
[Transformer TF300T Android Development] lollyjay:
Why don't you just not root it?
[Transformer TF300T Android Development] fred_bra:
Can I just simply skip the "flash SuperSU" part when flashing a new ROM?

Won't it break or something?

I have never considered this possibility
[Transformer TF300T Android Development] lollyjay:
Yes that should work.
[Transformer TF300T Android Development] kozmo2k4:
I think it is SUPERSU that has the ability to hide/temporary unroot, just for that purpose...

Hi why isnt there a Nougatella for TF101 please? Or is it still in development?????
[Transformer TF300T Android Development] gc2712:
I think KatKiss-7.0_TF300T_008 was OK. Its working (I think) at the moment, but will privide logcat etc if it stops working again. I suspect it maay have to do with disconnecting the tab from keyboard, but will have to do more thorough checking before reporting back.
[Transformer TF300T Android Development] pastorbob62:
Well I downloaded and installed -012 along with the latest gapps after a full wipe. It looked very promising and things were going along very smoothly until I was playing Hay Day. After a couple of minutes, the app stared reloading and looping through the reload process. exiting and restarting didn't help and neither did powering down and rebooting. I finally had to boot into recovery and restore my nanroid backup.

Not sure what is causing the issue but I am (and have been since release) running -008 without any issues so I guess a will stand pat for now. Maybe even permanently. Apparently something in the 7.1 update is causing problems.

Good work overall though.

SD Card issue

Hello,

I just installed v012 but I cannot use my 32b SD card, during setup it halts at 20% formatting and after that it's listed as -13.62 used of 14.68gb.

I already tried reformatting the SD Card in Windows (which works fine) and rebooting the tablet but this does not solve the issue.

I also have an issue with the SD Card in the dock, it is recognized but I cannot use it.

Both SD cards can be mounted and used under TWRP, but not with Nougatella.

Anyone else had the same issue and could resolve this ?

For the rest, no issues to report, very smooth installation and very fast responses using the rom.

Thanks for the good work to keep the TF300T alive Timduru !!
[Transformer TF300T Android Development] ebonit:
I don't know what your statement "but not with Nougatella" means.

TWRP is an application and Nougatella is a CR like an OS in general. So please find an App like "File Manger" at Google Playstore and install it. After that you might be able to use both external SD cards easily on your tablet.
[Transformer TF300T Android Development] FVM427:
Hi, what I mean is, that when in recovery mode under TWRP, I can access and use both SD cards.

When I boot my tablet with the Katkiss - Nougatella #12, I cannot use any of the SD cards.

When I mount the micro SD card in the tablet, I receive a notification that an SD card is mounted and I get an option to use it for transfer of files or ar extension of the internal memory. Both options require however that the SD card is formatted, the fortmatting procedure however stops at 20% and ends after a couple of minutes with a timeout message. After that , the 32 gb SD card reports -13.62 used of 14.68gb instead of 32Gb.

I used several different SD cards which I formatted first on my laptop, using FAT32, exFAT, NTFS and EXT3, but all gave the same result.

I also tried rebooting wiht the SD card mounted but this did not change anything either.

When I load an SD card in the dock, it is even not recognized and not mounted and therefore not accessible.

I hope this makes some more sence about my issues with the SD cards ? :confused:

Thanks in advance for any support !
[Transformer TF300T Android Development] ebonit:
Please note, any SD card must be in format FAT 32. That's very important!

In case of the above mentioned notification you have to decide for transfer of files

only

. If you decide to extend the internal memory, you may throw away your SD card. You never can use it as an extern memory on the tablet again or re-format it for other use.

Conclusion: take a brand new card and format it on your PC as FAT 32. Then put it in your tablet and decide using it for file transfer, data and pictures and your issue will be solved. Don't forget to install a File Manager.
[Transformer TF300T Android Development] mumblyjoe55:
Running into some more connectivity issues, currently on Nougatella 12.

1) Anyone had luck with Bluetooth tethering? I can see other Bluetooth devices but when trying to connect to my phone (Galaxy s5) however doesn't seem to work. Other devices connect fine to my phone and have full use of the net.

2) Chromecast. Has never worked for me with Katkiss. Always shows error that tablet is not optimised for casting. Today I tried the app second screen as has been recommended elsewhere for the error but no luck. Ideas?
[Transformer TF300T Android Development] compact_wisdom:
You mean casting the screen to the chromecast? Because in general using Chromecast with the tablet works perfectly fine, for Netflix for example.

I have never tried mirroring the screen...
[Transformer TF300T Android Development] mumblyjoe55:
I've tried both casting and mirroring. At best, it connects but tablet freezes. Tries with Netflix, chrome and google home app, no luck.

Regarding Bluetooth, tested with a few more devices. Will not connect with any other android or ios device but no issues with a set of Bluetooth speakers.
[Transformer TF300T Android Development] reisa:
I'm having the same issue using a 64gb card that had been working fine as internal memory through 3 previous dirty flashes and one clean wipe & flash. After formatting the card for internal memory it ends up saying "-xx.x of xx.x available." It shows as a separate card rather than internal.
[Transformer TF300T Android Development] compact_wisdom:
Just tried again (normally i use my phone, therefore i wasn't sure if i used it with android 7). Casting Netflix works without problems for me.

Out of curiosity, tried to mirror the screen. On the tablet, everything looks like it works, but the screen stays just black.
[Transformer TF300T Android Development] mumblyjoe55:
Had a bit more of a play. It looks like the issue is around screen mirroring, particularly from Chrome.

Was surprised to find Netflix is casting fine (previously always timed out or crashed). Youtube fine too. With Chrome, it sometimes does cast and play, but tablet freezes, Chrome eventually crashes though the video may continue to stream. Screen mirroring of desktop, websites etc simply doesn't work.
[Transformer TF300T Android Development] compact_wisdom:
If I recall correctly it never has, with previous versions.

[Transformer TF300T Android Development] ebonit:
Please stop any attempts you have in mind. Download Rom, OpenGapps Arm 7.1 pico and SU again from post #1 and put them on your external SD card. After that make a clean re-installation (format /Data!!!) following the instruction in post #1 exactly. If done, please report the result! Thanks. :)

Thanks for the excellent software and the hard work. It runs smoothly and quickly. In addition to the known problem (recording audio) I have only seen 2 other: freezing screen when recording video and the bookmarks in the browser are not preserved. With Google Chrome it is not a problem.
