Yes.
[Transformer TF300T Android Development] pastorbob62:
Hmmm, that is the correct order to flash. And I'm assuming when you say you wiped data that includes formatting it? When I formatted my data partition I did the ext4 format first then reformatted to f2fs. That seems to work for most everyone. I am having no problems whatsoever with downloading and installing from Playstore.

If you haven't already tried the reformat then I suggest giving it a whirl and reflashing everything. Don't get impatient because it takes 30 - 40 minutes for the first format to complete.

Good luck.
[Transformer TF300T Android Development] Theziggy:
So everything working for you on ext4? No lengthy optimizations on tablet reboot?

How did you restore missing apps from recovery - also was it one at a time or batch mode?

EDIT - ah TB update.zip and restore from recovery - nice tip, thanks
[Transformer TF300T Android Development] pastorbob62:
Hey robgee! Long time no see!

I found that fresh install of my apps and restoring data only from Titanium BU works best in this transition. Haven't seen any issues going that route.
[Transformer TF300T Android Development] vif81:
Auto-rotate fixed here with #9! Thanks [MENTION=3951330]timduru[/MENTION].

It also fixed my connection to Google Drive (in v8, the app asked me to add a different Google account...)

My BT audio issues (explained in the LP thread) seem to be gone!

Well, what an awesome job you did!

Amazing stuff as always with this ROM.

We don't make mistakes, We just have happy accidents.
[Transformer TF300T Android Development] kriscodian:
I tried one last time, formatting to ext4 and then back to f2fs, and then followed all the steps. For some reason it works this time :D Thanks for suggesting the reformat.

Just want to report after change data to f2fs, the installation of ROM V009 run smoothly and no more error. I also don't have any error during restart tablet. Infect shut down and restart system are pretty fast. Really love it.

After install "Check my android" i found that my Gyroscope& E-compass are not working, this can confirm my hardware issue and the auto rotation should be working for others. Anyway anyone know how to fix the hardware Gyroscope issue?

info : actually my tablet motherboard was dead back to a year ago and lately i get a used replacement from ebay and change it. At last i bring back my dead tablet alive and start installing custom ROM. May be the used motherboard have the hardware issue. i guess...

Incredible, after CM11 and CM12.1 on the TF300T, trying #9 of your rom is so fast, all performance issues of CM are gone. I keep on testing with the list of apps I need.

Too bad that there is not that many well maintained roms for the TF700T, which currently feels a lot slower than the TF300T.

Things I miss from CM, are those available on your rom? I'm not even sure if those are CM-specific features or just dropped from AOSP.

Opening the lid was always very slow to activate the screen. Sometimes I even needed to press a button and wait for 10 seconds or more on CM. But with KatKiss the display is not activated at all, only by Power button. Any setting?

PIN security has no option for quick unlock, that means no need to press "ok" to enter the pin code. Any option?

Which scheduler do you recommend? Currently I selected the sio, after using noop in the past on CM. /data is f2fs already. As for the governor I always had ondemand, also on my plain linuxes, but I guess I'm going for the pegasusq (for multi-core support) or interactive (for faster responsivness).
[Transformer TF300T Android Development] nilssongrey:
I agree, #9 is definitivly slower than #8. You can download #8 fromthe Mirror-link ön page one.
[Transformer TF300T Android Development] timduru:
Those who find #009 to be slower than #008, could you try to reflash #009,

reboot and see if you still have issues.

If you still do, then flash one ot these:

Tim_KatKernel_023d-1_TF300T_MM6.0.zip

Tim_KatKernel_023d-2_TF300T_MM6.0.zip

Tim_KatKernel_023d-3_TF300T_MM6.0.zip

- one at a time, then reboot

- let it settle a couple of minutes

- test to see if it solves your issues

- flash the next kernel, and retest (no need to reflash the rom everytime, just the kernel)

Then report which kernel(s) are faster for you

Also extra question: are you using ext4 or f2fs on /data ?
[Transformer TF300T Android Development] Theziggy:
I made a Titanium Backup recovery flashable zip, installed #0009 - format data - change to f2fs - booted first, then rebooted into recovery - went to flash Titanium Backup Zip and it said Failed to sysMapFile - so couldn't update from Recovery - anybody got any clues as to why?
[Transformer TF300T Android Development] nilssongrey:
Reflashed (dirty) and rebooted. Seems to have done the trick, tablet as fast and smooth as when on #8.

Thanks for the new launcher, love it!

[Transformer TF300T Android Development] chrismine:
It seems that number 3 is the fastest then 2 and 1. Cache formatted to f2fs. The tablet was unusually slow before flashing the kernels. Wiping cache and Dalvik made no difference.
[Transformer TF300T Android Development] ddd3astra:
Not knowing what else objective to do, I ran Quadrant over the following configurations (/data on f2fs):

Dirty Flash of #009 from a few days ago: 5874

Re-flash of #009 today: 6472

Kernel 023d-1: 6671

Kernel 023d-2: 5890

Kernel 023d-3: 5947

Kernel 023d-1: 6430

So reflashing the original seemed to have the biggest effect, with kernels d-2 and d-3 seeming to have a hit on performance. Yes, I followed the procedure and waited some time for it to "settle down" before testing. (Once I didn't wait on purpose and got a 5070 just after it rebooted).

I am going to stick with the d-1 kernel for now and see if it gives a subjective performance boost on actual use.

Dirty flash from #7 to #9, the interface became freezy... I did a factory reset then changed system to f2fs, then flashed #9 (I checked that system was ever in f2fs after flashing #9), then flashed SU beta (the one in the 1st post), system is back to ext4!! (Checked from the change/repair page).

That's weird! Is anyone can tell why and what to do to keep my system f2fs?

Is there any difference between the regular twrp-2.8.7.0-tf300t.img and the KANG version? What I noticed is that 'reboot to ...' in this regular version does not reboot but always comes back in recovery. I always need to reboot by longpress the power-button. Is that better in KANG TWRP?
[Transformer TF300T Android Development] vfrvulcan:
Same here using 009 - did you find a fix?
[Transformer TF300T Android Development] vif81:
I tried couple more things : flashing #9, SU 2.52, Gapps together (with a queue) leads to an error when flashing Gapps. I needed to falsh these alone. Flashing #9 an Gapps (without SU2.52) leads also the system to revert to ext4 (according to the change/repair page)

I'm getting lost...

---------- Post added at 03:27 PM ---------- Previous post was at 03:24 PM ----------

This ROM (as has been stated on this thread and the Lollipop thread) only works with /data formatted to f2fs, not /system or /cache or /anything else

Fortunately system is automatically reset to ext4, so no damage done. But that means my question is still valid, anyone knows the reason why I get this error when trying to set data to f2fs?

Installed KANG and it works like breeze! Everything is running as adviced now. Reboot is much faster now (no 10 minutes "optimizing 1 of 1 apps" anymore). Got the feeling that #7 was still a bit faster than #9, but I am happy. Tim will work this out.

One very small bother: when placing app icons on the main page in the ultimate right column, the icon always jumps to the page to the right of it. I worked it out by first placing that icon one column to the left and then placing another icon on top of it, forcing the first one to jump one place to the right (just were I wanted it). If this is the only bug I will find, I am totally fine :)
[Transformer TF300T Android Development] pastorbob62:
Wasn't trying to be a s------s my friend and there is no reason to resort to profanity. However, in my personal experience and reading what others have posted on numerous devices over the past couple of years, 90% of the time problems occur because steps have been skipped or shortcuts taken. I have been guilty of this myself. Though I quoted you, I didn't mean you specifically but rather most of the problem posts I have seen in this thread. Read back over the last several pages and you will see to what I am referring. There are numerous posts illustrating my point. Add to that the fact that most of the users on this ROM are not experiencing issues then what is the most obvious possibility? It is either not following instructions, or they have restored an app that is causing problems. Or a hardware issue, though that is not likely since they usually came from a setup that worked well. Maybe it is the second possibility that is causing your sluggish performance?

These forums have megabytes of posts from people who have not followed the install instructions or thought they knew better than the developers. ;)

Actually it is. Step 3 - "Make a full wipe / factory reset (you can skip this step if you're already on the same main version of KatKiss,

if ever you encounter a problem do a format data and try again before reporting )"
[Transformer TF300T Android Development] Theziggy:
Hi Pastorbob

The 'Make a full wipe / factory reset (you can skip this step if you're already on the same main version of KatKiss,

if ever you encounter a problem do a format data and try again before reporting' is referring to what to do in the event of a dirty flash being unsuccessful. No reference to changing. /data to f2fs. Not being pedantic but stating a point.

Have flashed the third kernel and the ROM seems nipper :)
[Transformer TF300T Android Development] pastorbob62:
I suppose it is in the interpretation of the step, but I see your point. However, if your read through the posts, several people have had issues after a clean flash without data formatting that cleared up after reflashing with a data format. I guess it all ties back to the caution that is repeated ad nauseam throughout these forums about researching everything before you flash a new ROM. And formatting data is a suggested fix for issues on numerous devices.
[Transformer TF300T Android Development] Theziggy:
Quite, changing from ext4 to f2fs is mentioned extensively throughout the posts. But formatting data is NOT the same as changing /data to f2fs. Changing to f2fs is changing the file-system, not formatting /data. The formatting data is mentioned and reiterated as part of a Clean Wipe. I think you and I both know this PB, it's just that people get mixed up between formatting and changing file-systems etc.

All I am saying that is changing file system to f2fs is an integral part of getting the ROM to work best, it should be mentioned in the OP. (Mind you, some people on ext4 seem to be having no issues!)
[Transformer TF300T Android Development] pastorbob62:
You keep referring to changing the file system and formatting /data as if they are two different things. Not to split hairs but when you change the file system you are formatting. You can't change file systems in any OS without formatting. And the /data partition is the only one that should be formatted to ff2fs.

However, I understand that you are talking about the "format data" button (which formats ext4) versus the advanced "change file system" button and I agree that changing the /data partition to f2fs should be one of the steps in the instructions. :good:

What's weird about the lag is that once it comes there's no getting rid of it. Not even a reboot. It can work fine for a few hours, but as soon as the lag kicks in the only way to get rid of it is to reflash the ROM. So far though, 023d-3 seems to have improved my situation.

Question: is super SU mandatory for this ROM to work?

If so, why do why is it needed?
[Transformer TF300T Android Development] ringdingx:
Legendary ! ! !

So this ROM (#009 with the default kernel) had absolutely NO problem running Kodi 15.2 & streaming x264 720p AAC, AC3, or DTS .mkv files over SMB shares. I get NO wifi drops. I let Kodi's player play a full season of Shameless.US (x264 AC3 .mkv's) and it didn't even get warm. Was OMX/OpenMax added? It barely ran the battery down! Truly amazing. I DID "tweak" my ASUS router's 2.4Ghz N channel to "N only" and set the channel bandwidth to 20/40 MHz because ONE mkv on an OLD drive was dropping frames. It runs ASUSWRT custom firmware, not sure the rtr's stock FW had the option.

@Timduru This ROM is A-MAZE-ING!! Thank you thank you thank you (ad infinitum)!! :victory:

Two small questions: The dock's right-click -- when i use VNC doesn't do anything. EDIT: CTRL+ Left Click is == Right Click so problem solved.

Question the second.... on this Android Modders page http://androidmodguide.blogspot.com/p/io-schedulers.html The author (he/she also has a link to XDA thread about i/o on homepage of link above) says:

BFQ:

Instead of time slices allocation by CFQ, BFQ assigns budgets. Disk is granted to an active process until it's budget (number of sectors) expires. BFQ assigns high budgets to non-read tasks. Budget assigned to a process varies over time as a function of it's behavior.

Benefits:

- Has a very good USB data transfer rate.

- The best scheduler for playback of HD video recording and video streaming (due to less jitter than CFQ Scheduler, and others)

- Regarded as a very precise working Scheduler

- Delivers 30% more throughput than CFQ

- Being constantly updated

- Good for multitasking, more responsive than CFQ

Disadvantages:

- Not the best scheduler for benchmarks

- Higher budgets that were allocated to a process that can affect the interactivity and bring with it increased latency.

As I am sure there are many opinions on this.... It does say best for streaming HD video. But the kernel could make a difference and render this un-true, could it not? I left mine set to ROW @ 1500 (all the defaults, really). Can it HURT to try BFQ with the included kernel in #009?

So people wondering about other's experiences with this ROM, In my exp... Every app works, 1st boot after flash optimized apps 1-64 or so in a few minutes... sat on app 64 or 65 for maybe 10 minutes, the FLEW threw to 69. Video (720p x264 AC3 AAC DTS) streaming is perfect. Cannot wait to see how much better this can get. IDK if it mattered but since i came from 5.1.1, i also wiped /system (using lj50036's TWRP KANG) which is sharp and without errors, that i can see. If you want your TF300 to rock again, stop using it as a doorstop and FLASH FLASH FLASH ! !

[Transformer TF300T Android Development] mattgren:
Formatting (rather than just wiping) data will wipe all of your downloads in that partition. So that this doesn't happen, the files need to be on a different partition or disc.

An external card is the easiest way of doing that.
[Transformer TF300T Android Development] vif81:
Well, it's normal that if you wiped your data that all yours files too... :)

You just need to find a microSD and copy the files on it.
