Yes..agree...as this machine doesn't have a lot of support for it so any support is a good thing..

Only reason I have one is in picked it up for $50 and its actually feels like a nice little unit..so sometime soon in the future someone around me is going to get a good little machine that is running a stable lollipop version.. Who's it is I don't care..
[Asus  Eee Pad Transformer Prime] lj50036:
If you say so.....:confused::confused:

I just wanted out as I am not going to have time to do anything for this rom .....

Thx Josh
[Asus  Eee Pad Transformer Prime] dgcruzing:
Josh,

All good, look forward to playing with anything that you put out..

As I am not beholding to anyone Rom or Kernel..As is most users, we are a fickle lot.

But my comments still stand, as I flash and follow a large number of developers and understand that it can get frustrating as a developer\rom supporter to field the same basic questions time and time again.

Wish you well and just think of this thread not as a competing thread but as a thread that takes a bit of stress of your reading and answering.. As I see you have spent considerable time answering posts across threads.. and would love to see you keep doing that for the benefit of all those that still hold one of these machines..

yes, there shouldn't be any animosity as stated,

its a thread to take people off the original TF300T threads and to take them away from your modded version..

too much drama going for such little return so its better to give people an out and let them banter elsewhere..
[Asus  Eee Pad Transformer Prime] huskerkate:
Damn, I flashed the v15 for the tf300 with the compatibility pack, and it just didn't run as well on my device as Josh's tf201 v14b. Looks like i'm SOL unless Tim's tf300 versions get more compatible somehow. .... and just when this POS was starting to show some life.

Thx Josh
[Asus  Eee Pad Transformer Prime] dgcruzing:
No.. dont take that personally.. it was not aimed at you.. :cowboy:

but the tone of the thread in general the way it was going..

We can agree there is a lack of support for this device among developers..

and at this stage there is no dedicated single developer with a rom that they can call their own..

and as the TF range is not supported by updates by Asus then it stands to reason what little support in the forums will be used..

So all good..

this is a win/win situation for TF201T users..

and those that want to explore the new found freedom of flashing and making this tablet at least useable..

As I have stated before. .. I kinda like it.. and when I had it on 14b I had it stable..

its just that I am a sucker for punishment that I like to look ahead at where it could be...

and while I do that I dont want other posters giving me a hard time where to post..

thus....this thread has been created..

yes, I am still playing with it over the next few days... could even end up back on 14b..

As we know.. not all machines are the same..

my most stable was on Tims V14b with compatibility before I played around with F2Fs..

So there could be a slight difference in chips, screens that makes one work better than the other on the different versions..

Dear I ask.. if Josh wants to answer...

What actually is the difference between the two?

As for me so far I would say..

its only script tweaks to reflect that its infact a TF201T and deletion of the .int script..

As Basic Rom is same and Kernel is Same.. ?

As noted I am on the Grimlock 5.0 kernel now... so any upgrade by hardslog is going to be a bonus

TF201 Reverse Axis

I got a new screen for my TF201 and it is the model that it seems all of eBay has which has the reverse axis issue. I know there's a way to fix it which would mean having to recompile the kernel with the fix in the touchscreen driver, but I was just wondering if anyone had done it for themselves and they could post their kernel or driver here. It's usable with the keyboard/mouse but I didn't get this for a small laptop. ;)

Question: How to root on 14b with Grimlock 5 kernel

Now 14b (KatKiss Q&A TF201T ) thread is closed, so we cannot post there.

However, I have a question my configuration: 14b and dirty flashed Grimlock 5.0 kernel (I did the same [MENTION=3212674]dgcruzing[/MENTION] wrote there)

Now I lost root and don't know how to root again. I tried to use "Superuser-3.1.3__46___-efghi-signed_Final", which failed at TWRP.

My TF201 works fine, stable and fast, so I will stay at 14b+Grimlock 5, but would like to have root access to have TitaniumBackup working, for example.

Could you tell me how to root it again?

Thanks in advance,

[Asus  Eee Pad Transformer Prime] TacoNikky:
You should go to twrp/wipe/format data then type yes

It takes about 90 minutes to format

Make sure that your battery is full

Do Not interrupt format(if you do, it will brick)

After it's done, go and change /data to f2fs ;)

Dear friends

I have a new problem as Mr. Gneechee But with a little difference.

I followed the instructions correctly, and used the linked files. But after flashing I'm stuck in a boot loop.

When booting, I get 4 Tuxes:

... message length: 9

######## starting ##########

Detecting file systems . . .

mcmblk0p8 /data on internal (UDA) -> f2fs

mcmblk1p2 /data on microSD ( for Data2SD/ROM2SD) -> not present

mcmblk2p3 /system on microSD (for ROM2SD) -> not present

....

Then the Prime reboots and repeats the same.

Aslo I used recoverys Twrp 2.8.5(Tf300t).blob and Twrp 2.8.4(Tf300t).blob. But I have the same problem.

How can I remove this problem.

Is the problem of Twrp Tf300t?

If yes, can you Tell me the which recovery is appropriate?

Thanks a lot

Flash TWRP 2.8.5.1

Wipe everything using TWRP. I have also wiped Data partition and set it to EXT4 (I had lot of FC on F2FS before)

Then reboot and Flash in one run:

- KatKiss #22

- Grimlock Kernel v 5.1 (not lite)

- Minimalistic Google Apps

It works greate without any FC and it is fastest ROM that I had on TF201.

I see in drop down menu new option "Cast screen" but don't have miracast reciever. Can someone test it please?

question about "system/etc/initd/10kat"

Hi,

I am running Katkiss v19 on a TF201 with grim5

Battery drain of 1% every 3-5 min.

First, many thanks for your efforts and clear instructions. I have followed them successfully, but any KatKiss ROM I've tried including

the successful install according to your great instructions has very rapid battery drain on my TF201. Eg( 1% every 3-5 minutes).

I'm wondering if:

Anyone else is experiencing battery drain like this

If so can anything be done

There is a possibility that my battery has gone bad but I've lost track of what the prior burn rate was in so many struggles to get my TF201 running decently again.

Ideas?
[Asus  Eee Pad Transformer Prime] TacoNikky:
Battery drain is like what you experienced on your tablet. It's because of the grimlock kernel's settings. Kernel is overclocked to 1.8 ghz and also gpu is overclocked. Main problem is voltage values: they are set high and causes twitches/glitches on prime.

For better battery life, i recommend you to flash grimlock lite kernel which i use recently. Battery life is significantly better because voltage values are well set and twitches are gone. I think you should try it :cool:
[Asus  Eee Pad Transformer Prime] vanquishe:
Hi TacoNikky,

I have followed your instructions and so far its been great when the TF201 is up and running.

I do face a weird situation which baffles me and was hoping if you could advice.

When i leave the tf201 alone for a long time, eg overnight.

In the morning it does not wake up. When I try to power it up, it goes thru a few boot-loops like this:

Device unlicked screen -> Penguins -> reboot -> unlock screen -> penguins -> katkiss rectangle logo -> reboot

-> unlock screen -> penguins -> katkiss logo -> animation logo....

Sometimes it will incrementally reboot and finally get into desktop.

Sometimes it just gives up and goes to black screen after few boot loops . In such case, i go into recovery and clear dalivik & cache

and it will boot up fine.

Im using the lite 5.1 kernal you posted, also deleted 10kat as suggested.

If this will help, my performance setings are: min 204, max 1300, sch is sio.

Also, this is not a battery drain issue. I go to sleep at night with 97%. Morning is like 94-96%.
[Asus  Eee Pad Transformer Prime] TacoNikky:
it's called SOD (sleep of death), kernel&rom related issue. But generally it happens if Wi-Fi switched to always on in settings.

Can you please check your wifi settings? Set it to "never" and i hope it will be fine then :cowboy:
[Asus  Eee Pad Transformer Prime] Jamonroad:
Flashed GRIMLOCK LITE 5.1 on TF201 to see if it resolves battery drain

I just flashed "GRIMLOCK_LITE_5.1_signed.zip" as you suggested. I flashed it over your above mentioned process and then wiped the Dalvik and Cache.

I'll let it charge fully and run it for a couple days and report back so everyone can benefit from this thread.

Thanks so much!

Update: 22-Apr-2015

Battery drain is about 1% every 10-12 min. now, so flashing "GRIMLOCK_LITE_5.1_signed.zip" did double the battery life, but it's still pretty extreme.

- All auto sync for apps are turned off

- Performance is set to: Interactive - 120 Min. - 1200 Max.

- Minimal apps are installed

- Wallpaper is set to black

I'm wondering if my battery is bad??

Anyone else experiencing bluetooth issues on this lollipop 5.1? Bluetooth connects but everything is stuttering whether I'm using video app or music app like play music.

KatKiss didn't kiss me...

Thanks for the ROM! Works realy nice.

But I have some issues to be solved. Audio latency haven't gone as I expected (though on nexus 5 it was solved after installing official Android 5.0). So I wonder is this KatKiss still works on Dalvik?

And durind installation I didn't have a f2fs format option in TWRP so I left the extF4. May this cause problems with latency?

Is their an option to convert file system to f2fs without re-install? And how do I get the f2fs option in TWRP?

V28 and trying data2sd with a 64GB card, someone has experience with this?

Hi,

I am running the KatKiss rom v28 right now, standard download from TimDuru's site combined with the GrimLock kernel, SU & GApps, is running stable but do want to try data2sd as I read a lot of positive aspects on the IO performance. Following this rom from v14, really nice work and keeps my 'old' tf201 still a daily used device!

The microSD card is a ScanDisk Ultra 64GB class 10 XC1 card.

Reading around, it would be 'just' to make 2 primary partitions, the first FAT32 the second EXT4. Kernel has autodetection for data2sd, put the microSD card in the tablet, do a clean system install and boot ...

When doing this, I ended up with an 'Encryption Unsuccessfull' screen ... Looking this up, could be because my card is not supported ... however when formatting the full card as FAT32, the card is fully recognised, I can format via TWRP, ... this let me believe the hardware and firmware does support this card.

Another read was talking about removing the journaling feature of ext4 as the solution for this 'Encryption' problem, did this but still the same ...

Tried a lot of combinations, smaller partions of 32GB, EXT4 and F2FS, ... always the encryption issues as result.

The rom also supports system2sd, by adding a third partition, as EXT4. So maybe the rom expects this setup. GParted again the microSD card ... Booting the tablet indeed triggers the data2sd and system2sd on booting. There is however a remark of an unsuccessful cp commaond, something with ramdisk that could not be copied from systemx ... the tablet continues booting and runs, no encryption error, but it's running on internal memory, so no data2sd setup ...

After numerous combinations of partitions, filesystems, sizes, .... still no luck :( So hopefully someone can give some directions of what is going wrong.

Thanks a lot,

X Axis Problem

I just installed a new digitizer and I'm one of the unlucky ones with a reversed x axis. I found code to compile a new kernel to fix this but I don't know what all I need. Is there a guide to help me find all the files I need? I know how to compile standard linux kernels but getting everything I need for Android requires a bit more info. Or perhaps someone has already built a kernel for KatKiss 5.11 to switch the axis?

The post I'm looking at says:

4. Find lines:

if (mxt->max_y_val < 1024)

ypos >>= 2;

stored_x[touch_number] = xpos;

stored_y[touch_number] = ypos;

fingerInfo[touch_number].x=xpos;

fingerInfo[touch_number].y=ypos;

Replace with

if (mxt->max_y_val < 1024)

ypos >>= 2;

xpos = mxt->max_x_val - xpos;

stored_x[touch_number] = xpos;

stored_y[touch_number] = ypos;

fingerInfo[touch_number].x=xpos;

fingerInfo[touch_number].y=ypos;
[Asus  Eee Pad Transformer Prime] Angelwind:
I believe some of the devs here have incorporated it into their kernels, you'll just have to look. I do have a zip file for the driver on here (search for posts in my username) that you can use to compile your own kernel. Some of the devs have their own source that you can use to compile your own kernel using the modified driver if they don't have support for it. I sold my tablet months ago, so I haven't been keeping up with development.

Once the driver is complied into your kernel, you just need to send an echo command to the proper driver to turn it on. I don't remember if I included an init.d script with my driver, but that isn't hard to set up if you can compile a kernel. You can do a search on the driver name as well and it should turn up the instructions on how to tell it to send the command to flip the axis.

I did the upgrade on my stock TF201 a few days ago, and I'm very impressed with how responsive my TF201 is now. I wasn't brave enough to go for v30, as there were some reports that v26 was more stable.

I experienced the SOD after the first night, but then I installed the 'Timed Toggles' app and set it to put the TF201 into aeroplane mode from 23:30 to 7:30 each night. I've not seen the SOD problem since.

Battery life is amazing; I last charged it 30 hours ago and it's only down to 78% (helped by overnight aeroplane mode).

The only minor issue I'm seeing is that the screen brightness varies for no apparent reason. I used the IPS mode while on the stock firmware and that worked perfectly.

Thanks to all who have contributed to this excellent upgrade. I'd like to make a donation, but I don't know how.

v26 is more stable because multiwindow feature is added after version 26. But it differs device to device, if multiwindow is important for you then you can give a chance to v30 ;)
