Thanks. Under Settings / Developer Options / Apps / Select runtime. On changing it suggests you visit http://source.android.com/devices/tech/dalvik/art.html before you do anything hasty. Requires reboot.

After Reboot, my settings still show I'm using Dalvik :(

EDIT: SOLVED thanks to loner and LDBAKE who advised I need to be without alternate browser and without Xposed Framework. Uninstalled and ART now up and running. Note: first boot takes a while for ART to optimise apps.
[Asus Transformer TF700] loner.:
Remember if you have the alternate default browser loaded ART will not work you will probably hang at the boot animation. :)
[Asus Transformer TF700] norkle:
Fortunately don't have the alternate browser installed. However my attempts to change to ART are still being thwarted. Appears to happily make the change and reboot, but after reboot still on Dalvik.
[Asus Transformer TF700] LetMeKnow:
After changing to ART, did you wipe "dalvik and cache" before booting back into your system? :D
[Asus Transformer TF700] LDBAKE:
I seem to remember sbdags mentioning that "Xposed Framework" will also cause problems with switching to ART.

Using this ROM loaded internally, the USB adapter works for me. FAT32 format only, though, for the attached thumb drive.
[Asus Transformer TF700] osvaldoll:
Thanks for your replay. I just installed (again) the ROM internally and the USB don't work, The pendrive is FAT 32 format toó. I don't know what happened with my device. Perhaps it is a kernel problem

rom2sd and f2fs

sbdags

First I want to say thank you for making such great roms. I'm using both CROMI-X 5.4 and Crombi-kk. If it hadn't been for these roms I wouldn't have kept the TF700.

I have CROMI-X 5.4 on the internal and Crombi-kk on the external as ROM2SD. No problems and great speed with a SANDISK MicroSDHC Ultra 32GB class U1.

I have for some time been trying to get f2fs to work with rom2sd with the above configuration. But, I end up with encryption error every time. After what I understand the two most obvious reasons for this is that either /data on the external sd is not f2fs or the installed Crombi-kk kernel is not f2fs compatible. I am 99.9 % sure that the /data partition is f2fs. At least it is not ext4 :). Both gparted and twrp format have been tested. I chose ext4 internal and f2fs external during install.

As I wrote in a previous post about the fstabs:

-Internal / seems with ext4 for all internal partitions

-Internal/system/boot/rootfs_data2sd seems ok with f2fs for /data and no discard option

I have tried to grab a logcat over adb but I have not been able to get contact. The adb interface in windows 7 device manager appears for some seconds and then dissapears when the encryption error emerges.

Do anyone have a suggestion to what to do/check next?

Perfect instal hardly a single issue

A big well deserved thank you to sdbags, _that and lj50036 for all their hardwork on our TF700T .

Tf700T 64 Gb

Crombi-kk 0517

I had it installed since it came out with no issues what so ever only that it is unbelievably fast scoring about 8700 - 8900 on quadrant with no overclocking on internal f2fs and _that.

My only query is that it runs all sort of videos and games I throw at except for the embedded vids on fox news.I tried other flash players / browsers but no change it leaves a blank black screen instead of the video.Only difference from my other( wife) tab is the bootloader one is us and mine is ww. Could that be the cause ?

Keep it up Guys.

Thanks

I tried 3 different pendrives with the same result.

The ES File Explorer shows the internal SD, external SD, and the options from the dock, SD, USB0 and USB1. Clicking on the USBs, nothing happend,

With the USB inserted, If you go to >SETTINGS> Storage> USB, the buttons USB (2nd group) "mount SD" and "delete USB" are actived, but if you push it, nothing happens. If you disconnect the memory, then, the buttons go to disabled and the memory extracted message appears on the motification bar.

Really the tablet knows that a pendrive is connected, but It can not read..
[Asus Transformer TF700] sbdags:
It's cos they use flash, and KitKat doesn't support it as Google changed the stock browser to chromium. In the installer choose dolphin and flash and it should work.

Please find both the fstab.cardhu in both /system/boot/rootfs_rom2sd as well as in the /system/boot/ramdisk on the sd card. I note that the /data partition pointing to mmcblk1p2 on the external sd in the ramdisk fstab is still ext4. Change?

Yes, XPosed breaks ART (or vice versa, actually).

[Asus Transformer TF700] loner.:
No I do not mean Dolphin.
[Asus Transformer TF700] norkle:
Sounds like I have an almost identical setup. But I can't make out all of the details.

Are you getting the encryption error when you're booting with the microSD in or out (or both)? How do you know how the filesystems are setup? What did you use to format the partitions on the microSD? Have you only followed the instructions in the Dev forum post, or anything additional? What kernel are you using?

To my (very limited) understanding the message that encryption failed may be due to attempting to read an F2FS /data when your partition is still EXT4. Use GParted to double-check that your microSD is partitioned as FAT32/F2FS/EXT4. If not, there's your problem. If it is, suggest you post some additional information.
[Asus Transformer TF700] sbdags:
Ramdisk doesn't matter in this case as it must get overwritten by the /system/boot one.

You are set up for ROM2SD and with internal on ext4 and external on f2fs - correct?

/dev/block/mmcblk1p2 /data f2fs noatime,nosuid,nodev,nodiratime,errors=recover wait,encryptable=footer
/dev/block/mmcblk0p8 /datai ext4 noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,errors=panic wait,encryptable=footer
[Asus Transformer TF700] johnlgalt:
Then what do you mean?
[Asus Transformer TF700] loner.:
The alternative default browser.

- Added an Alternate Stock Browser as an option that appears to work better than the CM11 one :)
[Asus Transformer TF700] johnlgalt:
gotchya. Default threw me off, didn't think about that option.
[Asus Transformer TF700] Kmist:
Thank you for your reply and input. See below for details.

Correct. I have Cromi-x 5.4 using the _that v4 kernel working fine on the internal. Naturally, these partitions are ext4. On the external I have installed the 140517 version using the _that v9 OC kernel. I chose rom2sd + internal ext4 and external f2fs during the install. As mentioned partition 2 on the sdcard was first formatted to f2fs using gparted. I understand there is a bug that makes f2fs partitions show up as unrecognized in gparted. I have tried both with and without an additional format using twrp f2fs version. I use the rom2sd1.zip posted in the OP before I format the data partition in twrp.

I get the encryption error when I boot the tablet on the external. I should mention that some weeks ago I followed the instructions in the f2fs MOD post http://xdaforums.com/showthread.php?t=2681775 That means that the files in the instructions under the rom2sd section have been installed. However, any changes made by these should have been overwritten by the crombi-kk install, right?
[Asus Transformer TF700] sbdags:
It sounds like it should work and you have exactly the same setup as me - CROMi-X on ext4 internal and CROMBI-kk on f2fs external.....

The only way of getting that error is if the partition is not f2fs or you accidentally made the internal f2fs and didn't realise? That is all I can think of....
[Asus Transformer TF700] awilson77584:
Hi. I formatted my microsd card fat32, f2fs, and ext4 partitions with gparted. Do I still need to install the f2fs version of twrp?

[Asus Transformer TF700] sbdags:
Well if you want to wipe, install to /data and do nandroids yes.
[Asus Transformer TF700] bluebirch:

[Asus Transformer TF700] CalPolyRock:
Lag!

I've been using various versions CROMBI and it's predecessors over the years even before sbdags took over.

I've used various kernels from Hunds to _that's.

I know that this tablet suffers from bad I/O hardware issues.

With all of that being said, I'm still looking to make the latest version of CROMBI-kk usable. Upon reboot, it's fairly smooth. But, as soon as it's been in standby and sleeping, or had an uptime a few hours/days, it will wake up and the lag will be so bad it's unusable.

If I launch any app, such as chrome, and want to type anything, the keyboard (mostly Swiftkey) lags between every letter after lagging to load.

I've wiped data and that will help a little, but I'm looking for a more useful solution. The lag reminds me of running on my old Droid Charge which didn't have enough memory and I needed mess with MinFree Values. I'm guessing that the TF700 is having lots of page faults defaulting to slow I/O. Not sure how I prove that though.

I'm surprised to hear that not many people complain about lag on the latest CROMI-kk builds. I just seeing people saying the last builds a fast & smooth. Other than not currently having a blank /data partition (I end up installing stuff because I want to use my tablet with some apps), I'm try to help debug to see what difference is between my laggy tablet and everyone else's blazing fast lag free one!

I haven't used ROM2SD or DATA2SD or F2FS yet. From what I've heard, it's only minimal improvements. But, if that is the sure fire way to go, I can give that a shot.

I'm currently using the latest 5/17 COMBI-kk, _that v9 (OC by default I think), and stock settings which means row scheduler, interactive governer, and I've tried both the performance and balanced profiles. I don't care about Quadrant scores, but it's it's typically 6000-7000.

Any other ways to diagnose the lagginess? Any recommendations beyond a /data wipe?

Thanks
[Asus Transformer TF700] lj50036:
Ok, I'm going to do my best at explaining this as I can....

The number of updated being done to the code on the upstream side is mind boggling :cyclops:

There are so many different ways this can go ....... Github and the way CM updates their repo's and then in turn the way

I update our reop's... Lets say for instance, by the time I get done compiling the base rom, there are going to be things that

have changed in the code, maybe CM reverted a change they found out was not good, in turn making our release seem

like shyt.....:D

I know I need to get better at making the change log, let me tell you its not easy and in very time consuming :silly:

I know some time it seems the rom is going in the wrong direction from this release to the next, but don't base your

experiences on one or two releases...

Thx Josh
[Asus Transformer TF700] berndblb:
Well, how did you flash?

fsync and journaling off? Those are the two options that would make the biggest difference in terms of lag.

And if CROMBi-KK doesn't work for you, try CROMi-X 5.4 - still the best rom for this tablet IMHO. Unless you have to have KitKat.....
[Asus Transformer TF700] CalPolyRock:
Different answer than what I expected or intended. No disrespect to all the hard work. I am software guy so I can appreciate the hours that you all put into the ROMs and kernels.

Most people seem to say that the rom and kernel are flying and mostly lag free. I'm trying to find out why I'm not there and how I can find out why.

---------- Post added at 08:55 PM ---------- Previous post was at 08:52 PM ----------

Yes. Fsync and Journaling off. I've also tried other options such as forcing gpu.

I've been on cromi-x before kitkat was out. I prefer kitkat because I want to run the latest Android for various reasons. Thanks for responding though.
[Asus Transformer TF700] lj50036:
No no... I know you did not mean anything by it, I was not implying you did :D

TWIP 2.7.0.0

I've done it in the past. Lately no for /data. Obviously /system gets by Aroma for installs.

10.6.1.14.4

Also notable selections on Aroma:

Standard ext4 (no f2fs, ROM2SD, or DATA2SD)

journaling disabled, 240 DPI, 1600x1000 sbdats speedy res, browser2ram, add block, disable fsync, zip align, no Xposed, I've tried dalvik and ART too
[Asus Transformer TF700] sbdags:
Ah for some reason 10.6.1.14.4 causes problems. Update to .10 and reflash and it might surprise you.

Easiest way is update with my boot loader and twrp package from the CROMi-X thread by flashing it. Reboot once and then flash the 2.6.3 that twrp from this thread.

Reboot once again then flash the ROM on a clean /data partition preferably by formatting it. ;)

Good luck. I'm very hopeful this will improve things.

[Asus Transformer TF700] pipopipz:
I got as far as flashing 2.6.3 that twrp and rebooting once. But when I go to recovery to flash again the Crombi ROM, it does not see anything in my internal and if I flash the Rom from the external, it says it can't mount the internal. Note: Already running on Crombi. Internal=F2Fs External Card=EXT4

P.s. - Looks like I have to flash the twrp-f2fs version from the F2FS thread for me to see again my internal from recovery. I am not sure though and I'm petrified of doing anything more until further instructions for fear I might do more damage than what I've already done. Sigh.
[Asus Transformer TF700] sbdags:
Yes you must flash a compatible twrp for f2fs - so don't use that's if you are on f2fs.
[Asus Transformer TF700] pipopipz:
My bad. Thank you sbdags!
[Asus Transformer TF700] awilson77584:
I was just reading through the F2FS thread and I came across _that's note that the rom2sd1 tool works at such a low level that mmcblk0p8 is the external sd data partition (http://xdaforums.com/showpost.php?p=51469551&postcount=27.) It brings me to wonder if I have misinterpreting the mount output while trying to get rom2sd to work with f2fs.

Could someone that has all of this working post their mount output under different permutations of the ext4 and f2fs partition setups? If it is a ridiculous, just say so. I'll keep trying to figure it out. That's half of the fun, right?! //smile

I have f2fs running with an internal setup and fat32 on my microsd now and I like it quite a bit. I may even stay with it for a while.

[Asus Transformer TF700] loner.:
I have tried this ROM in about every configuration. IMO crombi-kk on ext4 format for internal and crombi-kk f2fs format on the external sdcard is the way to go. ;)

I was using the mount cmd results to see if I did what I was supposed to do so the rom2sd with f2fs would work. I was wondering what a good configuration looks like (the mount cmd results.) Since there are multiple ways to combine the options, I was wondering what it would look like for the different options.

Maybe a better question is, are the different fstab files in the install zip or do you build them dynamically? I guess I could figure it out by looking at them. I've never looked inside the zip.

Just installed the new crombi update. I was going to switch to f2fs after all of the good hype about it. I was about to transfer all of my internal to a 16gb class 4 SD card but my tablet doesn't recognize the SD card. I plugged it into a windows laptop and formatted the external microSD to fat 32 but still nothing. It works fine in my phone. Any ideas?
[Asus Transformer TF700] awilson77584:
Thanks. I definitely messed something up along the way. I didn't get an /datai mount.

Thanks!
[Asus Transformer TF700] CalPolyRock:
I upgraded the bootloader. Any idea why a bootloader could affect system performance?

I also realized I had four a smaller slower SD card in my tablet instead of my 32gig class 10 card. I don't really use it for much, but some apps do put a secondary Android data folder on the card so maybe that also contributed?

I also formatted data then restored apps via titanium backup.

We'll see how this setup does.

What's the typical/normal lag? (which is hard to quantify)

does starting chrome or any other apps lag occasionally or all the time? Does a keyboard take a while to pop up and sometimes lag on some letters when typing? Or is everything pretty smooth and responsive everywhere? Just trying to understand what to expect and what's normal.

Thanks for the responses.
[Asus Transformer TF700] Kmist:
Yes, it is a little strange. I even tried wiping the internal and do a fresh CROMI-X install, with no luck. If the internal was f2fs CROMI-X wouldn't boot as _that v4 isn't f2fs compatible. Using the latest version of gparted 18.0-2 I get an unrecognized partition after a f2fs format. I see from the feature list of gparted that one needs the blkid command from util-linux v2.23+ for f2fs detection http://gparted.org/features.php.
[Asus Transformer TF700] Kmist:
f2fs and rom2sd working

Well. I got rom2sd and f2fs to work. But only after flashing the _that v8 f2fs kernel after installing CROMBI-kk 140517. Now, the pre-init script is showing at boot. I am not sure if it is supposed to do that with the as-installed CROMBI-kk as well? Anyway, it seems like it was the kernel that was installed that was not f2fs compatible and not anything with the /data partition.
[Asus Transformer TF700] sbdags:
Tell me which partitions you have set as f2fs and which kernel from the installer wasn't working (_thatv9?)

Sorry you already said ext4 on internal and f2fs on external - same as me - and it works fine here. ...... ??

EDIT I'm pretty sure that kernel you linked to has both internal and external as f2fs ..... weird

EDIT2 - yep if you use the that_f2fs + ROM2SD from that thread it expects both to be f2fs - see below:

/dev/block/mmcblk1p2 /data f2fs noatime,nosuid,nodev,discard,nodiratime,errors=recover wait,encryptable=footer
/dev/block/mmcblk0p8 /datai f2fs noatime,nosuid,nodev,discard,nodiratime,errors=recover

so that means your internal is not ext4 as you think it is ;)
[Asus Transformer TF700] Kmist:
I chose _that v9 and internal ext4 and external f2fs in the installer. The log is attached.

Well. The internal is indeed ext4 as now the encryption error has switched to the internal CROMI-X ;) Do you have a link to the relevant that v9 kernel with f2fs only for the external? Let's see what happens then hehe...

Accidentally posted this in the TF300 Q&A thread but it should really be here. Sorry.

Hi,

I'm using ROM2SD with CROMBi-kk latest on both internal and the SD card, using the bundled _that kernel and am trying to get dock USB tethering (reverse tethering? Using a USB cable to my phone to access the internet when there's no wi-fi) working. I think all it needs is the rndis_host.ko kernel module...but correct me if I'm wrong.

I have built that module and copied it to /system/lib/modules. If I insmod it I get a warning in dmesg saying the version magic 3.1.10-10.6.1.14.8-that4+ should be 3.1.10-10.6.1.14.10-that9-oc+ but it seems to load anyway. However it doesn't create the usb0 network interface that I was expecting (the phone is plugged in and USB tethering is turned on).

So, first question: Does anyone know if any other modules are needed?

Secondly, it looks like I pulled the wrong kernel sources from Github. Is there a repository with the latest _that kernel that's used in CROMBi-kk?

Lastly, sdbags/_that/lj50036...thank you for making this ROM! I love it. Once I know which things are needed, would it be possible to include these modules in the next build?

Thanks!
