Hi Guys,

I got issues when trying to install this ROM. I got the tablet with out the dock connector.

I have the correct twrp recovery version to flash the rom, when I flash it, with/without gapps and supersu. I get one of these issues

* Boot Loop

* Blank screen after asus screen for a while then it reboot.

I tried system and data as f2fp and ext4 file systems.

I've downloaded older releases, I even tired a android 5.1 release of katkiss and its the same problem.

I checked the files with their sumchecks, all are correct.

What am I missing out here guys, as I have followed the instructions as they are in the first post.

Its not my first android device I have used custom roms before on other devices, done it atleast half a dozen devices or so. First device I haven't been able to boot.

EDIT: also when booting the display flashes really quickly white, sometimes.
[Transformer TF300T Android Development] AndyTommo:
Have you done a clean install following the instructions on Page 1? Hopefully this will clear any issues.
[Transformer TF300T Android Development] FingerlessGloves:
I have wiped data yes. clean install.

now I can't get my device in to recovery mode so I guess its bricked.
[Transformer TF300T Android Development] AndyTommo:
Do you have access to fastboot? if so you may well be able to reinstall a recovery, reload a back up or revert to stock so you can start again.

I installed a dual battery widget. It only recognizes 1 battery while the notification bar shows 2 icons (with 1 icon never changing from 99%...)

[Transformer TF300T Android Development] ebonit:
Dear friend, it is obviously where the mistakes are made. First of all, nobody told you to change /system to F2FS instead of /data only. There have always been warnings in the forum! On the other hand post #1 advised to install rom, supersu and gapps of your choise in one run. Then wipe dalvik and reboot. You went your own way.

Please restore your backup and try again a clean install using the instruction in post #1 strictly!
[Transformer TF300T Android Development] FingerlessGloves:
First of all you don't know when I started to try different file systems, this was way after trying different versions of the Rom and with and without the gapps. I was just trying different things to get it working. So there is no need to have ago at me when you only know half the story. I even stated I used the method on the first post "as I have followed the instructions as they are in the first post.". I put it back on ext4 on system and f2fs on data before it was bricked anyways and I'm not complaining its brick anyways.

Thanks you for help but I can't even get the device to the fastboot screen, holding the power and volume button, it just keeps rebooting. I left the tablet rebooting last night, to get the battery flat because I couldn't get it to turn off or anything. I shall try again later to see if I can get to the fastboot screen. If not then its bricked, its a shame but would of been nice to get a old device working new again, wasn't using it anyways due to the low android version, not much of a loss.

What version of stock Rom did you originally come from? You might have an out of date bootloader.

Re-download the rom from mirror site And the. Md5 file of the rom. Do a format data then change it to f2fp AND DO A NORMAL WIPE DATA this should be followed be install the rom. NB rom and mb5 on the external SD root.

I had same issue and was solved

[Transformer TF300T Android Development] Artemis-kun:
I'm seconding this. Though, if you can't even access fastboot, then asking this is probably pointless, as it sounds like you're pretty much stuck now. I'd check the threads on unbricking and see if anything can be made to work for you. Otherwise, sounds like the tablet may have bought the farm.

The only solution is exchanging the mainboard. I have been got stuck in the same situation 2 years ago and did it successfully. The tablet is it really worth!

Yup, just buy a 'parts' TF300 on Ebay. You can get the ones with the cracked screens all the time for less than the cost of a mainboard. Crack them open, swap out the mainboards and go to town. I have done it on two different TF300s now with no issues

#28 Install went perfectly!

Thanks again, Timduro! I dirty flashed over #25 to get the security updates and whatever refinement you have added. Once again, following your instructions carefully, all went smoothly. Making a backup was the most time consuming part of the process. I appreciate how you have made this old tablet into something very usable again. I'm actually using it more now than I ever did!
[Transformer TF300T Android Development] Artemis-kun:
Haven't bothered with this in a while, but I believe Trickster Mod is able to do this easily, and I assume System Tuner should be able to, as well.
[Transformer TF300T Android Development] walttheboss:
My dock also was doing very strange things. Disable all immersive modes under user interface. Then reboot.

Also can try boot to recovery and them reboot system. My tablet dock combo work much better after those two.
[Transformer TF300T Android Development] Matchless 2015:
Updated TF300TG from version 026 to 028 doing a clean install and also flashed nano Gapps. Really outstanding work by Timduru! Everything is fast and smooth!

Just a question on the TF300TG, I still have WiFi not connecting automatically after a reboot and an empty WiFi icon shows on the top of the screen. If I push the WiFi button on the dock then WiFi is switched off and if I push it again it comes on and connects properly and will stay connected for the rest of the session.

Am I missing something here? It was the same on 026.

Thanks.

Hi, [MENTION=3951330]timduru[/MENTION].

I've started this year with katkiss for my TF300TG. I was suprised for too much increase of speed and other tweaks! Thank you so very much! I've seen one message in this tread (but unfortunately forgot where) about the second life for device - I fully agree! My devise is actually reborned! Please continue support of this wonderful!

And I want to understand nature of freezing video in browser. Let me remind you this issue: in Chrome video is playing while you don't press full screen. In fullscreen video is freezing but sound is playing. If you press back, sound is stopped, and after 5-10 seconds Chrome crashed.

I've noticed it happened NOT ALWAYS. There are sites where I press full screen and video is playing excellent (BTW, 720p) and after pressing back it also works (one on flashplayer, one on html5). But also I know sites with this issue (e.g. on one site video 720x400, .mp4). And mobile youtube is with this issue. And also mp4...Maybe it's codec problem? Hope you'll think about it! Don't waste your time!

Solution: use Google Chrome Dev! This version of Chrome works perfectly! Issue is gone!

Thank you for rom again! :)

Stock Browser Bookmarks Sync Issue

First off, awesome work timduru :good::good::good: I've been using your kitkat release since the final version and have been reluctant to upgrade to lollipop or Marshmallow due to being a power user and having many small tweaks and tools in place that aren't compatible with Lollipop onwards. I decided it was time to try out you latest creation and start testing what does and doesn't work with regards to my tweaks and tools. So I jumped in on marshmallow version 27 to test and found it to be extremely stable and smooth and with the addition of xposed working perfectly, I've managed to setup all my requirements again. so looks like I'm moving onto marshmallow permanently.

There is one issue I have come across which I have been unable to fix

I have tested the bookmarks sync in both releases 27 & 28 but it fails to sync always.

The stock bookmarks sync was added in release 20 according to your change log.

Can anyone else confirm this? Check Settings>Accounts>Google>Bookmarks> toggle on and see if an exclamation mark appears next to it with a message at the bottom advising "Sync is currently experiencing issues, please try again later"

I've never had any issues with the stock browser and have used it since the gingerbread days. Chrome is just way to big and bloaty for the TF300 and so I could really do with bookmarks sync working for stock browser.

Thanks timduru for all your time and effort creating these extremely smooth and stable ROM's for us transformer pad users. For devices with very little RAM and poor I/O speeds, these katkiss ROM's are a must.

Regards

Scott Almond

I have the same problem too with all the versions of this rom.My model is tf300t. Does anyone has a solution to this?? I tried clean install and every new version I install, I first wipe system partition. Otherwise excellent work and performance.
[Transformer TF300T Android Development] RudeboyXL:
When I first flashed Marshmallow v27 from Kitkat v36, my WiFi automatically connected fine every time after a reboot. I was testing xposed compatibility and had to reboot several times when enabling modules, and I can confirm WiFi definitely connected automatically every time. Then eventually I found some compatibility issues with a certain module and a few other apps and so performed a factory reset on the Marshmallow v27 ROM. From that point on, WiFi never connected automatically even after another factory reset or cache wipes or even flashing v28.

Maybe coming from kitkat v36 to Marshmallow retained some WiFi driver code? enabling WiFi to work perfectly?

Maybe after factory reset, this "code" is lost resulting in relying on Marshmallow driver code only?

I'm no expert, I'm not sure how the WiFi support works, but I know it won't be as simple as you'd expect, especially with all different hardware out there. Maybe our WiFi chip has some built in cache/memory and retains this through flashing a ROM? but looses this following a factory reset and reboot?

This seems to be the one main issue I can see effecting this ROM. WiFi not auto connecting upon reboot/power-on is a big deal for myself as I have various remote tools that need to work following a remote reboot of the tablet etc.

Just some food for thought. I may try reverting back to kitkat and then try flashing marshmallow again to see if I can replicate the working WiFi again, but it may be a couple of days before I get chance. (Unless anyone knows of a reason I shouldn't try? like incompatibilities to downgrade to kitkat now I've moved to marshmallow?)

Bluetooth needs a double toggle to enable for me also, not a big deal as I rarely use it and it's not difficult to double click the quick settings toggle to enable it. although a fix eventually would be nice.

Regards

Scott
[Transformer TF300T Android Development] compact_wisdom:
Did you format data when flashing from kitkat to mm? Probably you should try that first.
[Transformer TF300T Android Development] RudeboyXL:
All lot of people on here suffer the same issue, so is obviously a ROM bug.

But to stop the barrage of obvious questions, yes I can follow basic instructions and even if the instructions, weren't in the original post, I've never dirty flashed a ROM. not worth the risk in my opinion. Every ROM I have ever flashed over the years has been a clean install from scratch including data wipe/format.

[Transformer TF300T Android Development] TheWooky:
Don't be rude, boy [emoji12]

I think compact_wisdoms question makes a lot of sense. Many people suffer from poor reading: "did you format?" "Yes, I wiped." We can not estimate your skills from a distance! You do know that formatting in stead of wiping may solve many issues? Most people do not.

A lot of people suffer from a lot of issues on numerous devices across this website that have absolutely nothing to do with ROM issues but everything to do with poor direction following skills. When you post minimal info about a problem you will get questioned about whether you followed the basic instructions. And wiping through factory reset is not the same as formatting the /data partition. Doing the latter will often times solve many issues.

If you have already formatted then

perhaps

there are issues related to the ROM. But in my experience 99% of the issues on ROM's this far along are related to devices, not the ROM's. It has been stated numerous times that there are different versions of the WIFI hardware depending on when you bought it. Since there seems to be numerous users without WIFI issues then I suspect this is the problem, not the ROM
[Transformer TF300T Android Development] compact_wisdom:
Too be fair, in my opinion it is up for discussion if it is a rom problem or not, when the problem occurs on some TF300 hardware and works fine on other. Not that it's worth the discussion ;)
[Transformer TF300T Android Development] AaronKal:
I'm getting a lot of reboots with v. 28 - I had none up until now, and it initially happened upon updating apps, or installing new ones. I'm going to do a clean install to see if that helps, but it's odd that it only has happened with this version. I've used every successive version up until now with no issues
[Transformer TF300T Android Development] diordnAMRZAR:
It's a good discussion, either way

Ok. So I'd like to help settle the question whether the wifi issue is a ROM or HW problem. I take the side that it's a ROM issue, and here's why: Looked around the tablet logs and saw one error for sure. this ROM does not detect that _I do not_ have a dock attached to the tablet. kmsg log shows an error message:

<3>[13326.861429] power_supply dock_battery: driver failed to report `capacity' property

The error repeats constantly -- several times per minute. And this quirk appears in the logs from both 027 and 028.

Interesting. I rolled back to a rooted Jelly Bean to look for the same error -- and never saw it.

Why should the system worry about a dock battery when the dock isn't present? Should this be processed conditionally? i.e

if !dock then; status_tablet_battery_only;

My take: this ROM sometimes doesn't properly detect the power state of the tablet, and consequently -- inadvertently sometimes puts the tablet wifi to sleep even when plugged in, and doesn't always correctly detect the power state at boot time either -- plugged in or not. But this doesn't always happen. Its a little spooky because sometimes I'll wake up at 02:00, grab my tablet and see it disconnected from the wifi, even while plugged in to the charger. And the last weather update will be about 3hrs prior. Other times the wifi stays solid when plugged in over night. My wifi settings are:

Keep wifi on during sleep: "Only when plugged in"

which is my desired working configuration. However the 'bug' is only a minor pain in the rear, considering how well the tablet performs otherwise with this ROM. I'd be happy were it to be fixed, but can live with this little quirk against the screen freeze-ups that gave this user fits enough to (almost) toss the tablet like a frisbee when running Jelly Bean.

It's worth mentioning: the one glaring difference from 027<>028 is [MENTION=3951330]timduru[/MENTION] re-introduced the optimization flags to the build process. Some years ago on 32bit x86 arch machines at least -- certain levels of gcc -O flags exhibited a bug that would remove code arbitrarily, and since -- I believe -- [MENTION=3951330]timduru[/MENTION] is using a cross compiling environment with the 32bit {target==mips} -- it's possible this -O bug has reared it's ugly head once again. Regressions, missed patches -- who knows? Worth examining perhaps???

And certainly it's always worth starting from scratch, doing a proper format/wipe especially when there are issues with the tablet. Asking someone if they did a proper format/wipe is a harmless enough question -- no one should get too bothered by this sort of sanity check. Good Technicians pose these sorts of questions to each other often. But just ask it with a smile :D

my ,2¢
[Transformer TF300T Android Development] RudeboyXL:
Apologies, I didn't mean to offend anyone, but it does become tiring seeing people fire off the same old questions thinking that they are helping, when the information I already provided specifically nullifies the question at hand.

If all was working perfectly following the initial ROM flash, but then later after a factory reset the issue occurs (not a reboot, rebooting caused no issues) (no flashing of a ROM taking place). How could a format or not format be responsible for any of this? Like [MENTION=5156419]TheWooky[/MENTION] pointed out, many people suffer from poor reading, and this goes for the majority of people not just the ones seeking help, but also those rushing to assist. repeat answers that only serve to clutter up an already huge thread with the same 4 words isn't help in my opinion.

Although I do appreciate the willingness to assist, sometimes its better to read again and think for a moment about weather or not your response is even relevant.

again I appreciate the attempt to assist, but your assistance was of no help. and has resulted in several large response that were also of no help and have further bulked up the thread with more irrelevant posts.

[Transformer TF300T Android Development] tetsuo55:
The thing people are asking is if you have specifically chosen to FORMAT data, which is completey different from wiping and takes forever to complete (70 minutes in my TF201.

If you have done this and still suffer from the issue please upload your logcat from a fresh 2nd boot after flashing or later. The first boot after a clean install is noisy and wont help.

I will look at the issue and see what we can do about it

Also please be aware that by using Xposed you are disabling a lot of optimizations timduru and I added to the sourcecode for art/dalvik so your performance and stability will decrease.
[Transformer TF300T Android Development] bda12pleaseu:
Hey all

Would anyone mind posting some optimization settings the are running. I'm interested more in a snappy response between changing apps and such. Happy to compromise in other areas.

Hi, Tim.

Thanks for keeping our TFs up to date. I see lots of activity in your github. Good stuff ahead!

I think there is a small bug with using a hidden SSID. After being connected to a hidden SSID and leaving the tablet idle, sleep mode starts. When coming out of sleep, the tablet doesn't reconnect to the hidden network. To reconnect, I have to toggle wifi on/off. This isn't a big deal as the workaround is trivial and I don't normally use a hidden network. I'm travelling now and the network I'm now using is hidden. This happens with my TF101 too (which I've had to take back from my daughter due to a broken touchscreen with my TF300T). Both tablets are using v28. I'll post logs later, but thought I'd give an FYI.

Thanks again for KatKiss!

Any chance to use 3G on TF300TG with this rom? Maybe adding some kernel module? I seem to be one of the very few owners of this model and none of the couple of roms supporting 3G has ever been updated for years...

EDIT: XDA's new layout got me confused, I didn't notice there were 169 pages of comments already..

EDIT2: Jolly good! After a short search I've figured TF300TG can use 3G with this rom installing Widget 2 from Play Store!

Argh... I was about to flash the rom, when I discovered my TF300TG won't boot. I'm afraid the battery's dead. I've tried the pull out/push in battery plug pressing ON button for 30 sec, but it stays off. The green led is on, but the tablet won't turn on. I think I have to buy a new battery. I will update when I can to the thing, on Amazon it's 60 euros.

Thanks for the hint Matchless, but are you sure there are no VAT/tax costs? I'm ordering from Europe.. Besides that, I read the average shipment is 43-59 days...
