Did you try this:

Go to Settings > Apps > All

Select Play Store > Clear Cache & Data.

Select the app that was showing the error and Clear cache and data.

On the other hand it might be helpful to do a clean reinstall of Rom, pico Gapps and SuperSU after format data through TWRP. https://xdaforums.com/showpost.php?p=71839889&postcount=846
[Transformer TF300T Android Development] lcee:
Thanx! I tried all these solution, except for formatting. (Meanwhile, I started to do it, but it takes a long time because it has been running for some time. ) How long does it fit in general?

Which is the correct version number of TWRP? (I have used 3.0.2 and 3.1.0)

If all succeed you can definitely work in Google Play?

Surely there was something in the file system error.

Tim, Great work on V#22 My tablet hasn't run this well in a long time. I did a super clean install. I wiped and formatted everything and installed from the dock SD slot. I used Opengapp Pico and installed Titanium Backup. I then installed just the apps I needed via TB. This ROM runs super quick and is very snappy and responsive. I have been running it since Friday afternoon and I have not experienced one bit of lag. Again, super job on this ROM!! Thanks sent

MTP not working after installing #22

My system bootlooped continuously including in recovery after a normal shutdown on #21. So I erased all partitions and reinstalled stock. Then reinstalled TWRP Kang in OP, and followed instructions in OP to install #22, SuperSU and pico Gapps successfully - also Titanium Backup as zip.

Problem is that the TF300 does not now show up in Windows 10, or Linux mint 18.1. This is the case whether I have USB debugging enabled or disabled. Also, when I try to change option to MTP from charging in drop down notification, the radio button is selected, but when box is closed no change occurs [still in charging mode]. Tried changing default in developer options and the setting won't stick. It keeps reverting to USB charging mode. What else can I do to establish MTP connection? I have already tried using a different USB cable and different computers.

I don't know if its relevant, but when I tried adb to see if there was a connection (at all) I got the following result:

gc@GC-Desktop ~/Desktop $ adb devices
List of devices attached
????????????	no permissions

Is there a solution to adb as well?

EDIT: Just tried connecting through TWRP and both adb and MTP work fine. So it must be something wrong with the ROM settings?
[Transformer TF300T Android Development] timduru:
Yeah they borked it in 7.1.2

it will be fixed in the next version.
[Transformer TF300T Android Development] pe1dnn:
Wouldn't you need root permission to read/write to the device? I just tried this on mine while my TF300 is running V22:

pe1dnn@LinuxMint ~ $ sudo adb devices
[sudo] wachtwoord voor pe1dnn:
List of devices attached
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
015d15b4fc20180c	device

pe1dnn@LinuxMint ~ $

And it seems to work fine

pe1dnn@LinuxMint ~ $ adb shell
tf300t:/ # uname -a
Linux localhost 3.1.10-katkernel-tf300t-048+ #394 SMP PREEMPT Sat Apr 1 12:04:00 CEST 2017 armv7l

full_tf300t-userdebug 7.1.2 N2G47F eng.timdur.20170413.093445 test-keys
tf300t:/ #

So maybe try again as root...
[Transformer TF300T Android Development] gc2712:
Thanks for the follow up. I tried as root already and got same result, so only uploaded output from user cmd. Odd that it works for you and Timduru says (in post above),it's borked awaiting patching. Wonder what the difference is?

EDIT: Just tried again this morning after restarting tablet and adb works fine as user or root in ROM. Maybe just required a restart. Mystery! So I guess what Timduru was saying is borked is MTP, not adb - and MTP still isn't working for me.

[Transformer TF300T Android Development] RudeboyXL:
[MENTION=5354919]gc2712[/MENTION] Have you tried -> Settings -> Developer options -> Select USB configuration -> MTP

If "Developer settings" isn't in your main settings list, go to "About phone" and click on the build number several times until it advises it is enabled.

This apparently fixed the issue for many nexus users so suspect it's just that it's not enabled by default and needs manually enabling in 7.1.2 due to a bug.

Hi,

Can someone give me an opinion about how fast is this ROM versus katshmallow?

I have done a clean install, bit it seems so slow in response, so i went back to katshmallow.

Thanks.
[Transformer TF300T Android Development] rena_:
have you read about the optimization thing in the background after first start, which need some time and may slow down the tab?
[Transformer TF300T Android Development] joff1234:
Yes, i've read it. But after instaled the ROM, i've been with it for a couple of days before returning to katshmallow ...
[Transformer TF300T Android Development] gc2712:
Thanks for the suggestion, but it was one of the first things I did. I see that others are reporting mtp as working fine on #22 so I assume the problem must be mine. Just odd that it works in recovery, but not in the rom.
[Transformer TF300T Android Development] ebonit:
First of all, this Rom ist very fast and responsible! The progress is much better compared to previous versions. :cowboy:

However there are two questions left:

1. Clean install means format /data which takes up tp one hour. Did you it successfully?

https://xdaforums.com/showpost.php?p=71839889&postcount=846

2. Did you ever change /data to F2FS?

If the answer is yes to both questions, go to settings and check performance as follows:

-Set clock values on boot

-Set Governor on interaktiv

-Minimum frequency

-Current value: 204 MHz

-Maximum frequency

-Current value: 1500 MHz

-Boot value: 1500 MHz

-I/O scheduler current value: cfq

-Set value on boot
[Transformer TF300T Android Development] joff1234:
It's yes to both questions.

Still, i'll give another try this weekend, thanks for the tips.
[Transformer TF300T Android Development] ebonit:
You are welcome!

When you go ahead, please follow carefully the install instruction in post #1 step by step. To be sure delete your old zip files on your SD card and replace them with fresh ones downloaded from the links in post #1. Take care of md5 checksum.

Help please! Stuck on team win recovery project logo, can't boot!

Help please. I had issues trying to run 7.1 katkiss so I inadvertently choose the 3rd option to do a wipe when holding down power and volume down buttons. Now I can only get to the team win recovery project then it goes to the 4 penguins and says Old FW. This is a continuous loop/reboot. I cannot get into anything else and cannot power it down, even with the pin hole in my tf300t. Is there any possible way to fix this? Is there a bootable image somewhere that I can put on the micro sd card since there is no USB port? Help sure would be appreciated. I just want to go back to 6.01 ??? thank you anyone and all for suggestions! Cindy
[Transformer TF300T Android Development] ebonit:
Bad luck!

Before you do something that could brick your device make a Buster99:

https://xdaforums.com/showpost.php?p=44244313&postcount=12

Further on follow the thread where you'll find an answer on any question you may have. :cowboy:
[Transformer TF300T Android Development] Sindee75:
Ebonit,

I first looked at that thread and googled problem for 2 days before posting. That thread did not help me partly did not understand it or it didn't pertain to me. That's why I was asking if there is a boot image for a sd card? Don't know what bricked means, guess I will have to google that too. Sounds like this device is unremarkable now? Or way above my little head to fix ?
[Transformer TF300T Android Development] ebonit:
There is no boot image known for SD card. Believe me in your case the only possibility to rescue your device is to get back on stock rom Jelly Bean 4.2. That needs to do a Buster99 as I advised. However you must have access to the device via fastboot and ADB.

If so, please look here and go ahead: https://xdaforums.com/showpost.php?p=69652226&postcount=443

PS: When your tablet is in the boot loop hold the volume down button a long time in order to get into recovery. The three icons RCK Android Wipe Data should appear. In the left upper corner should appear the message "Starting Fastboot USB download protocol". Then you have access to the device via USB through your PC.

Should the action fail your tablet is bricked totally.
[Transformer TF300T Android Development] pe1dnn:
Bricked means your device will get the same usefulness as a brick, a stone you put in a wall. In the sense that it takes up space and can not do anything useful except of just being a glass panel with some electronics. Maybe you can still put it on display for people to look at it, but it will never work again without sending it to a repair shop.

So what you want is avoid your device becoming a brick, so be care full not to execute an action which shuts you out. The instructions pointed to by Ebonit should for sure fix your problem. Read the instructions carefully and make sure you understand. If you do not know what you are doing then ask a friend who does. Fastboot is the only working interface you have left, it is a thin line and if fastboot access is lost then your device became a brick. So it is important to ensure to keep fastboot working (after also loosing fastboot only device specific brick fix recovery files can save the device, but I don't think you have those and they need to be made when the device was still working fine, which is too late now).

Asus System bar lock & battery value

Hi all,

Thanks Timduru & team, this is a great ROM!!

A couple of questions asking for your help:

1) The TF300T stock ROM had an app called "Asus System bar lock" and I haven't found it elsewhere.

Could be possible to add that to the "Navigation bar editor"?

Or could you please suggest me some app names which allow to lock the buttons on the system bar?

This is useful to me: Stup id or not, sometimes I accidentally push the triangle / circle / square buttons while holding the tablet ...

2) How can I change just the size of the battery value only? The numbers are very small to read in my opinion

3) How can I add the battery value to the lock screen? Its kind of annoying the need to unlock the tablet just to know how much juice is left.

Thanks in advance for your help!

Regards
[Transformer TF300T Android Development] walttheboss:
Just did a fresh clean install of 22. Included format data to ext4 and back to f2fs. Pico Gapps. Smoother than 19 for sure and first indications are battery is better.

Two problems immediately. Can no longer get rid of the warning by the internet. Used to be able to set captive_portal_detection_enabled to 0 but no more. I get the "Connected No Internet" text on all my connections because I am in China and Google is not loved here.

Plugging the usb cable into my Kubuntu (Linux 16.04) computer will not transfer files. Notification comes up where you can change from charging to file transfers but it doesn't switch. You can tap all day on the Use for file transfers and it doesn't change. Dev options are enabled and USB debugging enabled. Using AirDroid so not a problem.
[Transformer TF300T Android Development] ebonit:
First of all I have to state that the old TF300T runs very well on version #22. Incredible good performance and fast responding. There are no issues certifiable. Battery drain OK.

Regarding your remaining WiFi problem you may try to rekeying your router. Go to your router's WiFi security settings:

-if WPA/WPA2 Group Key Update Period is zero or disabled, you must change it.

-Set WPA/WPA2 Group Key Update Period to 86400

-Save your settings and reboot your router.

On the other hand, could you restore a previous version that run well in the past, you have in your backup, in order to see whether the issues happen too or not? If not you should reinstall #22 again.
[Transformer TF300T Android Development] walttheboss:
Thanks [MENTION=7106193]ebonit[/MENTION]. I agree completely that the tablet combined with [MENTION=3951330]timduru[/MENTION] is amazing. I am very pleased. No complaints at all.

The issue I have with wifi is not a problem with the ROM at all. In Google blocked countries the wifi has a warning next to it. "Connected No Internet" The internet works fine. Google can't talk to its servers so it says no internet. I did make the changes you suggested in my router and there was no change. That is really not a big issue. Used to be able to clean things up with the terminal command I mentioned but that setting must have changed.

The USB issue may be bigger than my install. When I plug into a Windows 10 or Kubuntu machine I cannot transfer files at all. When I try to change the USB setting to transfer files it does not change and I cannot access the tablet with the USB cable. Does your 22 allow you to switch settings and move files?

If you let me know the best way I will grab a log and post it.
[Transformer TF300T Android Development] ebonit:
Thanks for pointing my attention on this case. What I never have expected it really doesn't work on #22. Same situation like yours. USB settings cannot be changed. Hopefully Tim is gonna to check it soon. :confused:
[Transformer TF300T Android Development] pe1dnn:
Tim mentioned before there are problems with this ("Yeah they borked it in 7.1.2"), so you have to wait for a future version where it is fixed or go back to the previous one.
[Transformer TF300T Android Development] walttheboss:
Yes you are right. I forgot about that. I will wait and flash the next version. This 22 is too good in other ways to go back.
[Transformer TF300T Android Development] ebonit:
You are right. It has been written by Tim. Thanks for reminding! :)
[Transformer TF300T Android Development] Okiera29:
You can always transfer the files to an SD or Micro SD card to get them onto or off of the tablet. This is what I do. Otherwise, yeah we are kind of out of luck till it is fixed in 7.1.x

Good day to all,

I'm back still trying to install KatKiss to my TG.

I reinstall original ASUS rom and then redo everything, as per OT procedure, to install KatKiss #22. Still coming to the screen block on the first Asus window or making boot loop if restarting. But yesterday I turn off the tablet and enter in TWRP, make a wipe to factory then turn off, turn on and I manage to see for the first time the KatKiss logo and even the 4 color circles going out and in and then ... tablet went off and boot loop to the ASUS windows.

I try to redo this but unfortunately didn't manage.

With those new info, some one could give me some idea where the problem is.

Hello, Tim. Thank you so much for this awesome rom and support.

Sorry for offtop, can you advise a mail client for our device? Non piggy app:)

P.S. i used swiftkey keyboard. I'ts a piggy app? coz, It slows down the system a little
[Transformer TF300T Android Development] ebonit:
I don't know what to you really want to figure out. There are two possibilities to find out piggy apps eating either memory or battery.

First of all go to settings -> Memory -> touch Memory used by apps -> a new window opens showing all apps of your device using memory.

Secondly open the app "GSam Battery Monitor" -> touch App Usage -> a new window opens and shows you all the battery eating apps.

Regarding your question about another e-mail client I'm simply using the E-Mail app belonging to the rom.

I have been using the browser that comes with the rom (katbrowser), but now get a message from Google that this browser is no longer supported. Don't want to reinstall Chrome because it was laggy and used resources. Is there an updated kat browser?
[Transformer TF300T Android Development] timduru:
No problem for me here atm.

where do you get that message,

and what is the exact message ?

Also did you do a clean install of 7.1.2 or dirty ?

could be linked to a webview update or something if you didn't do a clean install it might still be using the chrome webview.

Dunno about swiftkey, I don't use it.

I use K@Mail for email.
[Transformer TF300T Android Development] gc2712:
The exact error message is : "This version of Chrome is no longer supported. Please upgrade to a supported browser. "

It appears when opening gmail in desktop mode in the katbrowser tab [only way to add folders in gmail]. I can't remember whether the upgrade was performed clean or dirty from #21, but suspect it was possibly a dirty update.

How would I identify, and if that is revealed to be the problem, then remedy the chrome webview problem? Does it require a clean reinstall, or can I remove an app/files?

Many thanks for the fine ROM and your assistance.
[Transformer TF300T Android Development] timduru:
hmm, ok gmail website in desktop mode only, I can reproduce that.

Difficult to say why / what they are testing to say that though, maybe UA.

It seems to work fine though, did you try to just hit 'Dismiss' ?

Working ok for me after dismissing the message.
[Transformer TF300T Android Development] davidmorris:
yannmrt, you may have a simple hardware issue.

Several of us had problems with earlier katkiss ROMs due to a flaky power switch. It drove me nuts that I could run stock but katkiss kept rebooting/ failing to start

The stock ROM did not seem to have an issue, but there is a sensitivity to the later ROMs(maybe) that means you get the reboot cycle.

This type of fix worked for me: http://www.sbprojects.com/repair/tf300/index.php

if you google, there are other versions of similar issues with TF300 power switch and random reboot

Check your power switch before giving up on the Kat
[Transformer TF300T Android Development] gc2712:
I did just dismiss the message, and gmail does work, but was behaving a bit strangely - wouldn't load folders properly etc., so I thought it might be an upgrade issue. Not mission critical though.

Morning All,

Firstly, #022 is flying, love it.

Two queries:

1. I upgraded to #022 as I was finding increasing sluggishness and lag - on opening/ switching apps and on browsing(Chrome). This time I did a full clean install(as I usually do) coming from #018b including a format of /data. I am on f2fs

Has anyone else noticed this lag? is it Chrome?

This time I have just gone for pico Gapps with only the following extras(Android Device Manager, Google 'Office'(Drive, Docs, Slides, Sheets) ES File Explorer pro, KAT, Keep, Netflix, Google Photos, Splashtop, Sportablet, Spotify, Touchdown)

For now I'm sticking with Katbrowser, although I do miss slightly the pervasive browsing history memory across my other devices(Samsung S7 stock Android, via Chrome, and Windows 10 via Chrome)

Is it 'safe' to go back to Chrome or am I likely to find lag building up again?

2. I can't get the stock email client to log in to my gmail account, although Inbox for Gmail works fine.

Error message reads " !Couldn't finish. Couldn't open connection to server " when either auto or manual setup. And my password is fine. Can anyone help or shall I stick with Inbox? Just trying to make my TF300 as light as possible
[Transformer TF300T Android Development] ebonit:
[MENTION=1723865]davidmorris[/MENTION]

First of all, uninstall Chrome right away and take the Lightning browser as advised by Tim. Then keep the amount of apps as small as you can because of the memory. With about 40-45 apps in general try always to keep about 300 MB memory as stand by. Uninstall all apps you don't need daily.

Check for piggy apps from time to time by going to ->Settings ->Memory ->hit "Memory used by apps" and a new window opens and shows you the result.

On the other hand check post #786 and compare the advised settings there with your own performance settings:

https://xdaforums.com/showpost.php?p=71682995&postcount=786

Regarding your e-mail problem I would like to recommend to take the "K-@Mail" client as advised by Tim. You will be satisfied.
[Transformer TF300T Android Development] davidmorris:
Ok that's interesting.

K-@mail won't work either.

Notification shows:

"failed to send some messages

java.netConnectException: Connection refused"

test email stuck in Outbox

K-@mail offered to use OAUTH(which i did, it didn't work) but also if I try and enter account manually, same problem as stock email client, connection refused.

However, INBOX by Gmail (for my Gmail address)

and Touchdown by Nitrodesk(for my UK NHS Outlook Exchange account) both work fine on send and receive.

(I need a secure client for Exchange that has a password protected interface, or the NHS insists on overriding security protocols for the device)

It's probably something simple I'm missing in the stock email and K-@mail as I can't get them to work. As I only have 33 apps currently I'm going to uninstall K-@mail and continue with Inbox and watch the memory.

I installed over CM12 last night. No problems w/dock keyboard nor wifi.

I first upgraded twrp 2.8.0 to twrp 3.1.0 via fastboot, then installed the new ROM via twrp recovery mode.

I pushed the zip files to tablet via adb.

My first attempt I left /data as ext4 and I was unable to install apps (google play store error 963). Then I went back to recovery mode & re-formatted data as f2fs and reinstalled the rom, superSU & gapps-pico.

Next is to install my collection of apps. Would be nice to have a file explorer app bundled but its also easy to download via google play.

I had a lot of app bloat with CM12 so the clean install noticeably more responsive.
