Have that(grimlock 5.0) on previous version and with Omni 5.0 (by scanno/lj50036) but it was causing me twitching /blinking of the screen with opened virtual keyboard. With compatibility pack (which is basically grimlock 4.0 for Kitkat with additional stuff) this is gone and battery drain seems to be gone too (running now 12 hours, wifi on all the time and 6 hours I'm playing Spotify radio via BT adapter "display on" time 1hour and still 70%!! left!!! I'm happy man...

Thx to all devs, 2 years old slate, long abandoned by ASUS (concerned with making money, not user satisfaction) running Lollipop, I would never even hope!! So crazy :D
[Asus  Eee Pad Transformer Prime] pikul:
****** just a reminder, this thread its only for the version posted here by lj50036 for the tf201, all the stuff about the tf300 roms and new versions should be posted over there ******

Now about new grimlock kernel for lollipop roms, ive also flash it and at first boot i had the well known screen flickering, the not enough space message and still some battery drain, after a few hours of using it i did a reboot, clean cache and restart it.

Screen flickering its almost gone, only happens from time to time, screen doesnt go black anymore, theres no message about not enough space, wifi battery drain bug its almost gone, i cant really say its fully gone since miscellaneous its still there but i havent tried it on a fresh fully charge battery.

I guess its safe to say that a fresh clean install from lj's rom version 14b + gapps and grimlocks 5.0 kernel its a solid daily driver rom for anyone :highfive:
[Asus  Eee Pad Transformer Prime] JuraP:
That's why this thread is called KatKiss Q&A TF201T and not KatKiss Q&A TF300T... :D

But one more - pretty constant bug I do have on TF201 with Lollipop versions (present on Omni and KatKiss too) with timduru's compatibility pack (Grimkern 4.0) or with Grimkern 5.0 - it's Bluetooth bug....

After fresh start or reboot I'm able to connect to my SONY BM10 BT audio transmitter or BT headset and to stream music for hours. But if you stop playback for longer time or turn off BT, than when resolving playback, nothing is transmitted afterwards. Player (Spotify or Google music) shows its playing a song, BT adapter shows connected but nothing comes out of speakers. If you turn BT off, it says turning of but never goes really off and stays on, but can't connect/find any BT device afterwards... To resolve it, you have to reboot.....

BT bug

[MENTION=5123642]lj50036[/MENTION], Hi Josh, as I did write in my latest post. BT on TF201 is buggy - first start after turning on/reboot/ everything is OK - BT turns on, connects to headset/BT audio adapter/whatever....

When you stop playback and try to start it again it doesn´t work (player is playing but no sound) When you try restart BT, it doesn´t turn itself off - stays on and unable to connect to any device. Here a logcat - starting with try to turn the BT off....Lots of BT errors .....Don´t know if it helps.....

Actually.. To be fair to Tim and the TF300 crew.. Questions on the katkiss version for the TF201 should be held over here.. So maybe a dedicated thread for those that flash the compatabilty pack should be started..

And to clarifi.. The version in this thread is actually Tims work with a few script tweaks to show that it is a TF201 .. Same kernal as the TF300 flashed compatibility pack...and as LJ has stated he is not going to support this thread due to other commitments then really this thread could be moded in the kitkass 15b version..as I know I have flashed it as has a number of others..

So not to start a ****fight.. Suggesting that TF201 users should be posting in the TF300 thread is dead wrong..as it clearly states that Tim is not supporting it in that thread.. Users of TF201s are in fact lucky it works and should stick to this side of the fence with questions..
[Asus  Eee Pad Transformer Prime] JuraP:
I don't want to start any fight, at all - sorry for that slightly bitty comment, I only found it funny.

Nobody suggests (or did I overlooked something?) to post in TF300 thread and nobody expects Timduru's support for a TF201...

Kernel is not the same as for TF300T (IMHO) timduru is using his own KatKernel which causes scarry hard-bootloop at TF201. In compatibility pack is Hardslog's Grimkern 4.0+ with Timdurus tweaks to make it work with LP.

Only rom is the same and Josh (lj50036) cooked rom and kernel for TF201 together and tweaked it, to make us the life easier (THX a lot for it)
[Asus  Eee Pad Transformer Prime] djmcnz:
TBH this is a Q&A thread, whilst I'm extremely happy with TF201 support, this forum/thread is not the place to post downloads.

I appreciate the service being offered so much that if this message seems harsh then the OP can PM me and I'll make it right. :)

I'm willing to help to keep TF201 support alive.
[Asus  Eee Pad Transformer Prime] dgcruzing:
I was referring to this post as it is a little rude to be starting a post with a blatant misdirection of new TF201 users that are looking to flash this kitkass version.. And or the compatabilty pack..

As stated.. The ROM is cooked by Tim..

Kernel is hardslogs and the combo for the TF201 is here in this OP by LJ..

And a big thanks to all concerned..

So I can't see why someone would be steering TF201 users to the TF300 threads..as really the more TF201 users that use this combo and or the compatibility pack flash..then it stands to reason that the developers will support it into the future..as its sure not getting support by Asus.. (Rant over)..

14b is stable if flashed right...both with the OPs version and the compatabilty pack..

OPs version has screen flickers due to kernel it seems..and on F2Fs it didn't feel as stable ...

Tim's version with compatibility pack with out F2Fs was stable and fast for my one...

15b I am playing with and have had troubles getting it up and settled..

Changed data back to normal and did the mega full wipe...restoring everything now..been getting a few reboots as it loads updates from playstore ( 170 apps updating as I flash a TB backup pack that I did early December)..

As a note I am flashing 15b on TF101s, TF300Ts and this TF201.. So I get to see it in action across all devices.. ( why have one when you can play on all three [emoji12] )

Dirty flashing of Grimlock 5

I did the same dirty flashing as [MENTION=3212674]dgcruzing[/MENTION] wrote in the above partly quoted post, because I was having a lot of reboots.

No reboot for over 1 day already, some flickers as mentioned.

And I had experienced the same "that strange flickering /twitching with opened software keyboard" [MENTION=1197646]JuraP[/MENTION] mentioned a few times. But as he wrote, the trade-off is on the new SW side, thanks to [MENTION=2158597]hardslog[/MENTION], [MENTION=5123642]lj50036[/MENTION], [MENTION=3951330]timduru[/MENTION] and all of you on the forums! :)

[Asus  Eee Pad Transformer Prime] pikul:
I didnt meant to be rude, but if anyone read some pages back they could see that even lj50036 was discontent with the fact that quite a few users where posting about the rom made for the TF300, he made a moded version for us tf201 users posted in the first page wich is the one everyone its supposed to be commenting about here, you only have to flash his 14b version with gapps, no compatibility pack needed.

If users follow these steps i think the only bugs posted so far where screen dimming to much, not going off, battery drain on some cases, and apparently bt problems when playing music after not doing it for a extended period of time, wich by the way the first 2 i solved by flashing latest grimlocks kernel 5.0 for lollipop roms + cleaning cache.

[Asus  Eee Pad Transformer Prime] apartypooper:
I just had the android environment reload itself but the linux itself didn't reboot. The program I was using froze and I plugged logcat to see what was going on. There was a constant stream of events and a while later the android system restarted (those blobs flying around). And now android seems to work fine. Uptime (in shell) tells over 21 hours.

Just mentioning this here to remind that in some cases last_kmsg might not be the correct file to debug. Unless the user is paying attention, it may be hard to differentiate between these reboots.

Something to keep in mind ..... :good:

Thx Josh
[Asus  Eee Pad Transformer Prime] Mediadriven:
First off thanks for the guide. Really appreciated. But I've hit a wall.

I was already running crombi-kk so I had the bootloader/tf300 steps already taken care of. Entered recovery performed factory reset without wiping user data. Followed steps on the original thread including additional zip for our tab. Rom boits no problem and the initial config goes smoothly. That's when I run into trouble. Apps from the play store will not install. I get "failed due to unknown error code 972". I have tried deleting play store data and cache. Also tried deleting google account and re-adding it. Tried factory reset again and re-installing. Re-downloaded and replaced all zips and tried again. Also tried pa-gapps 5.0 alpha, still no luck. Am I missing something? Would formatting data partition be of any use? Any help would be appreciated.
[Asus  Eee Pad Transformer Prime] lj50036:
As per the the instructions from the DEV thread ..... So maybe wiping /data may be a good idea.... :D

If you hold off for just a bit I am going to upload a standalone TF201T zip for testing ....

I will post this in the OP also .......

Downloading, will post results soon.

I did the complete format. Hoping this all works for me this time.

Edit: it is working fast and smooth!
[Asus  Eee Pad Transformer Prime] JuraP:
Hi Josh, installed yyour modded version of KatKiss - it´s either my cursed slate or dying memory or some general I/O problem of Lollipop ROM - getting to set up the tablet was a hell because everytime when more "hefty" I/O operations were performed (restoring apps from playstore) the slate was constantly freezing and reebooted itself or has to be rebooted with long pwr button press. Last KMSG after one of such typical reboots attached, but I didnt see much of problems there... Don´t know if it helps or not EDIT: here a logcat with freeze while signig up to FB - so far( as a noob) I found some I/O Error within. The behaviour of the tablet also looks like that
[Asus  Eee Pad Transformer Prime] lj50036:
Well then dont restore any apps at all ..... Just install the rom boot it, installl gapps boot it , let it run for a whole day like this, then install one app at a time ......

I mean we are here to test and doing the same thing over and over expecting diff results does no one any good .....

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

Did full wipe this morning and installed test zip and gapps. Install went smoothly. First boot took about 10 minutes. Decided to treat it as new device rather than install google backup of my apps. A couple of things so far.

1: Tried to launch play store and got " app is not installed" message. Launched browser and googled play store, clicking on the link launched the app that is supposedly not installed.

2: so far screen has gone black twice and pressing power button brings it back.

3: In chrome beta, it has given me " page is not available" message and reloading page doesn't help. Closed chrome beta, re-opened it and all was fine.

I'll keep testing and report back anything else I find. Thank you very much for your work. I will test any updates you care to post.

Ok more to report:

Chrome beta does not play nice with this rom. Many fc.

Installed google launcher through play store and could not enable it in settings ( no home tab available in settings). Uninstalled it and flashed launcher from original thread and presto, home tab appeared in settings after reboot.

Not sure if you are aware of this or not but no advanced power menu in developer options.

black screen logcat

Screen going black is a recurring problem. It comes back when either power button or volume rocker is pressed. Attached is a logcat.
[Asus  Eee Pad Transformer Prime] lj50036:
Well there is alot going on in that there logcat .... :D

But something that is missing which is odd to me is this ....

D/hwcomposer( 144): hwc_blank: display 0: blank
D/hwcomposer( 144): hwc_blank_display: display 0: [0 -> 1]
D/hwcomposer( 144): hwc_blank_display: releasing buffer 0x35
D/hwcomposer( 144): dc_blank: display 0, [0 -> 1]

Everytime my screen goes dark or I tell it to go dark it say this ....

I wonder how yours is going black without the hwc knowing about it ?

Repeatable crash with terminal emulator :)

I have a repeatable crash with the test lollipop. If I start Terminal Emulator and run ls a few times (no su), my android hangs and reboots.

I did a complete wipe and didn't install any apps / updates / backups from google etc. I let it brew for a couple of hours before doing anything. Then rebooted and started the terminal and crash. The attached last_kmsg is after this.

Upgrading the apps from google does not change the situation (google, google calendar, supersu) nor does updating the supersu binaries.

System/cache are ext4, data/sdcard are f2fs. I hope the sdcard is not causing this :)

EDIT: Also to clarify, adb shell works fine, no crashes. I had also used for example "reddit sync" succesfully (incl. pictures, videos etc.) for quite a while before noticing this.
[Asus  Eee Pad Transformer Prime] Mediadriven:
Here is a logcat that encompasses 4 seperate occurences of the issue, the last one taking place just before I stopped logging. Thanks for taking the time to look into this. It actually just happened again while I was typing this. It's a weird and frustrating little issue but nothing I can't live with for a while given the otherwise smooth performance.
[Asus  Eee Pad Transformer Prime] das chaos:
Not true! I'm running lollipop now for almost a fortnight without major problems from the ROM's side. I have thumb keyboard, which causes freezes but it does that also with kitkat and dolphin browser does not allways play ball with lollipop. But all in all ART runs better than expected, if you don't make the mistake to restore from TB app and data. If you resore also data, you might suffer some fc, before app stabilizes.

There is one major flaw: bluetooth is not working, which deprives me of my boombox.

On the test build ?

Thx Josh
[Asus  Eee Pad Transformer Prime] SoTacMatt:
Good evening!

I ran the test build from last night. Prior to installation, I formatted everything except my external SD card.

Instead of restoring, I started a new build. Everything I wanted to use installed very quickly!

Has anyone else side-loaded CM File Manager and had it appear to lock up, but install anyway?

This is a device I use daily. I too had the screen just go black. I hit the power button and the screen came on and went right off.

Bluetooth worked fine for me (BLUETOOTH GPS module.) I didn't see the keyboard charging (it may have, I just couldn't tell.)

I must say, it installed faster than using the TF300T build with all the extra patching.

Considering what was done to accomplish on this old of a device, it is very good!!!

Thanks!
[Asus  Eee Pad Transformer Prime] JuraP:
Have the same issue - normally working and suddenly display goes off for no reason. , but if u press pwr button, it turns on and right off again, in logcat it says going to sleep by pressing pwr button. As the tablet would think it was up all the time. Next press of pwr and you are on lock screen... It does happen randomly in about 3-5 minute interval.... Will send logcat as soon as I'm at my PC . Anything else is great... Before the black screen issue everything was OK. Fast, smooth, only few hiccups on the start(as I posted above) but all has settled down. After about 8 hours the black screen bug appeared.... Bluetooth working, camera working, in Antutu 21 570 points....

[MENTION=5123642]lj50036[/MENTION] Here is the logcat from display turned of - happened prior timestamp 22:41:34.184 - that´s the point, where I tryied to wake tablet up and it went to sleep instead.

[Asus  Eee Pad Transformer Prime] Stargazer Optimus:
Would it be possible to have the kernel autodetect /cache to be f2fs? Motorola phones that use f2fs on stock ROM have both /data and /cache on f2fs while /system remains on ext4.
[Asus  Eee Pad Transformer Prime] lj50036:
The kernel is build for f2fs on /data , There would be no gain in formatting /cache to f2fs as the only thing that uses that partition is the recovery ....

I may be alone here, but I'm getting significant battery drain while idle. Hadn't noticed it before because I was draining the battery while enjoying the experience but the last couple of days have been busy. I'm getting 80% drain while sleeping over a 6 hour period. Left home yesterday at 9 am with battery at 87%, came home at 3 pm and tablet was at 7%. Today I left it at 97%, came home 6 hours later, 13%. Anyone else?
[Asus  Eee Pad Transformer Prime] huskerkate:
Yes, it is a common issue with all AOSP builds on most all devices (phone or tablet). If you will notice, one of the biggest battery culprits is "Miscellaneous". I dont know if anyone has identified the cause, but the issue is pretty well known.

Don't think, that GPS dongle ever worked on any of unofficial ROMs(at least in my case).

ext4 vs f2fs

I was having constant freezing using f2fs. Tried every combination to solve the issue: switching io schedulers, cpu governers, underclocking, different version of twrp (maybe the makef2fs command is different). The freezing all seems to be related to file io (writing?). Installing apps, watiching youtube, opening a new tab on chrome could cause my prime to freeze forcing a hard reset.

Another piece of info... If it freezes in the middle of multiple apps restoring, everything that was installed that session would not be saved... even if 5 apps installed successfully before hand and i even used some of them. The only way to ensure the installs would "stick" is to reboot after every install.

Ext4 on the other hand is working great! I can do a full tablet restore (16 apps) with no lockups. I've been on this image for two days now and so far much more stable... might be slower but cant tell with lollipop.

Hope this helps,

Digable
[Asus  Eee Pad Transformer Prime] JuraP:
Had the same - logcat already posted... brutal, IO related freezes, that required hard reeboot. I'm on f2fs too... So u've undergone the ext4, 90+ minutes Data format.....? Brave man... What recovery did you use for f2fs formatting? I think Josh is already aware about this issue..... Have all great week...
