I did a wipe of cache and dalvik cache and rebooted then let it sit about 20min. So far after using several apps and browsing online its been consistently smooth. Using that kernal with auto install optimal settings, tweaks etc on f2fs data partition and was installed internal.
[Asus Transformer TF700] _that:
No, that wouldn't make any sense.

What a surprise that the 2 years newer device with a less ****ty eMMC is faster. :)

Have you ever installed Linux on a flash memory card with roughly 1 MB/s random write speed?
[Asus Transformer TF700] Linuxguy1:
Many times. Live installs, temp OSes, etc.
[Asus Transformer TF700] _that:
OK, for many live installs nothing is written to the card. But if you use the card as a full root partition, you'd probably run into similar latency issues as we have on the TF700, and f2fs is supposed to improve this.
[Asus Transformer TF700] fonetval:
Can I suggest that - as you have added some option in aroma - it would be very nice to have an option to just flash one of the kernels you provide with ROM? I am often forced to do the whole process of install just to change the kernel option : even if the new option "same option as last install with choice" is really a great improvement, why flashing again all the stuff while flashing only kernel could be enough?

I know that I'm a bit lazy, but it's not so easy to find Zip of each of the compatible kernels (no obvious link I had Ave found so far) you offer in install...

What do you think of that?
[Asus Transformer TF700] lmmohr4:
And don't forget to run Data2SD1. zip or Rom2SD1 zip to take your external nandroid backup.

I was going to ask how TWRP was to know that /data was on a different partition, or needed to be flashed to a different partition, but I was just answered by [MENTION=4599122]lmmohr4[/MENTION]. Thanks!

---------- Post added at 03:01 AM ---------- Previous post was at 02:52 AM ----------

Not just "supposed to". When I first installed B2 I discovered the f2fs bug in TWRP 2.8.5 just after formatting everything. So I went ahead and installed the ROM with _that kernel, all internal, with /data as ext4. First time I ever had any serious lag problems with the tablet. Retrograded (is that a word?) to 2.8.4, changed /data to f2fs, re-flashed the ROM with the same options. Ran so fast it almost burned my fingers. Still does with a clean flash of B3, in fact it's so good I may just leave it there. Why fix it anymore? It's better than it ever was before.
[Asus Transformer TF700] sharkcow:
stupid question: why does everybody keep saying to fully format to ext4 (which takes 90mins!) only to format again to f2fs?! I've been interrupting the ext4 format in order to do the f2fs I really want every time with no ill effects I believe... or is there some technical explanation what happens on the emmc during these two formats that an electronics engineer would understand?
[Asus Transformer TF700] eRPeeX:
Question was: 'How to format?'

So answered that.

I interrupted once a format. Only thanks to Joshua expert help it is recovered from the 'soft bricked' status.

Now on B4:

Did first a change of data from ext4 to f2fs and there were a lot of problems, fc's, reboots, ...

Second a full format to ext4 and then to f2fs. Now it's working smoothly.

So fwiw, I think that a full format wipes all in a better way than a simple change to f2fs.
[Asus Transformer TF700] _that:
Formatting, that is creating an empty ext4 filesystem, actually doesn't take 90 minutes. The make_ext4fs_internal function that does this (which is from AOSP - TWRP only calls it) runs a "secure erase" aka "trim" command on the whole block device before it writes the new filesystem. This takes a lot of time because the eMMC controller erases all the blocks. Since flash memory cells can't be overwritten (only erased in large blocks and rewritten in smaller blocks), this ensures that when you write data to your filesystem, free blocks are available.

The mkfs.f2fs command line tool which TWRP uses for creating f2fs filesystems doesn't trim the whole partition, so it's much faster. But if your eMMC was filled with data before, the eMMC controller doesn't know that most blocks are now unused and it will have to erase blocks at the time you write data.
[Asus Transformer TF700] sharkcow:
thanks for this great (and quick) reply! that would mean it's safe to nandroid my current f2fs-install, let the ext4 format do its 90min-thing, return to f2fs and restore the nandroid which should give me the same benefit, right?

sharkcow
[Asus Transformer TF700] _that:
Yes, that will work. Note from Captain Obvious: your backup must be on external storage or on your PC while you format. :)
[Asus Transformer TF700] rprussell:
An interesting twist - I have this thing called "Cool Tool" installed, which tells me all sorts of realtime system stats, including how much CPU is being used and by what.

Now - after an initial internal install, since changing to DATA2SD have had terrible TERRIBLE lag when it wakes up in the mornings, after leaving it docked and charging all night.

The "current most intensive process" display on "Cool Tool" when it's awakened shows me 'mmcqd/2' during the laggy parts.

It's doing SOMETHING with the mmc, and it goes on for quite a while. Surely not restoring from swap space? :)
[Asus Transformer TF700] terribell:
I have been having some reboots due to out memory kernel panic but just had a strange one now.

This time it was not due to the memory and from k last msg I didn't understand what was the cause, I've attached it for help.

The thing that strikes me most is that the pad was unplugged and in the log I've several disconnects and connects. It sometimes starts to get warm and the battery icon shows like it is charging, but nothing is connected to charge.

Anyone seen any thing similar?

Just to clarify it is on b4 internal with omni kernel and recommended tweaks except browser2ram.
[Asus Transformer TF700] ph34rthesaint:
Please Help!

Please help, I seem to be stuck in a boot loop! The installation appears to go fine but the device can't boot.. It tries once and reverts to recovery.

I first upgraded to TWRP v2.8.5.0 (can't find latest TWRP blob anywhere and the app store doesn't update).

I tried various "internal" installation options and kernels but they all don't work (I often use the sdcard to transfer things).

I'm upgrading from miniCROMI-X.

Your help is much appreciated. Thanks in advance!

Hey folks - [MENTION=518363]sbdags[/MENTION] [MENTION=5123642]lj50036[/MENTION] [MENTION=4878287]_that[/MENTION] et al - it's been an awesome ride but I'm exploring another device with an active digitizer (samsung note) for a EMR project I'm messing around with. Been around since it was Scott's cleanrom and am very thankful that Mr. dags and the crew have kept the project moving forward.

[Asus Transformer TF700] Bobg1231:
I've been kind of confused on this "90 minutes" thing. Maybe if you format data more often it doesn't take as long? Whenever I go to format data in twrp, type in yes to format, it takes about 2 minutes. Am I missing something?
[Asus Transformer TF700] drewski_1:
F2FS or ext4?

Sent from my Moto X
[Asus Transformer TF700] Bobg1231:

To find the TWRP (the 2.8.5 has bug if you play with f2fs formatting) : here is a good place (thanks to lj50036)
[Asus Transformer TF700] ph34rthesaint:
Thanks, I've updated TWRP to 2.8.6.1 and reinstalled Zombi and it still has the same issue: appears to install fine but can't boot. Tries once before reverting to TWRP again.

Any other suggestions?

---------- Post added at 02:13 AM ---------- Previous post was at 01:19 AM ----------

Fixed it!

The problem was the ROM I used was corrupt or something. I downloaded it from the 2nd link and the checksums don't match. The first link works and I'm in!

Thanks for all the help. Looking forward to trying out Lollipop on this device!
[Asus Transformer TF700] lj50036:
Yep that happens, thus why we sign the zips .... :D

Thx Josh
[Asus Transformer TF700] _that:
Maybe you're using a build of TWRP that has been configured for fast formatting. The "secure discard" command that is sent to the eMMC can be replaced by a normal "discard" which may be faster, or the whole trimming process can be disabled altogether at build time.

It is also quite possible that these commands take less time on already erased blocks.
[Asus Transformer TF700] terribell:
Any insight on this issue?
[Asus Transformer TF700] _that:
13945: You pressed the power button.

13949: You disconnected the charger.

13966: Something was out of memory. The kernel started killing processes, starting with logcat (were you running logcat?).

13996: The oom killer kills more processes.

14020: Low memory killer kills processes.

14145: You pressed the power button.

14145: The kernel disables "power down in idle" due to some IRQ problem:

[14145.535203] Failed to register LP2 timer IRQ for CPU 1: irq=74, ret=-16

[14145.535272] LP2 in idle disabled

14375: CPU temp is rising. No obvious information which process is causing it.

15882: The oom killer is active again. Again logcat is the victim (did you restart logcat?)

The "USB cable detected" messages are indeed strange if you didn't plug or unplug it.
[Asus Transformer TF700] terribell:
Thanks for the analysis, to make everything clear I was not running logcat neither did the tablet was plugged in to charge or to a computer.

The tablet was sleeping and I just tried to wake it with the power button without any success, I did nothing else since it was not connected to anything and the screen did not turn on.

Most of the times the tablet gets warmer I can see the indication on the battery icon, like it is charging, and I was thinking it was something you did for overclock, or something similar, to increase performance.
[Asus Transformer TF700] Bobg1231:
Maybe I do it too often. It has always run relatively fast for me on various versions. Thanks for the reply!

[Asus Transformer TF700] _that:

[Asus Transformer TF700] terribell:
From what I've seen on your last kmsg, you are having the same problem as I've been having, kernel panic due to low memory.

Most of the times my tablet restarts is due to this problem and the only solution I've found is to uninstall apps that consume higher memory or hibernate them with greenify.

It would be better if the ROM could graciously take care of the memory problems with rebooting.

[MENTION=4878287]_that[/MENTION]

Sorry for bumping this subject but has anyone found anything on this peculiar behavior?

It seems I'm not the only one having the charging icon appearing when nothing is connected, as [MENTION=1621071]pjpettis[/MENTION] also has seen this happen.

Thanks a lot for the help, with the exception of this and the kernel panics due to low mem the ROM is perfect and by far the best this tablet has ever seen.
[Asus Transformer TF700] shonkin:
This issue is not one the log would show... but has anyone noted odd behavior when touching the screen? I sometimes get sudden menu drops (from other apps or Android itself) when inside the browser or even setup menus. I monkeyed around a bit with animation settings, first having them off and then set at .5 (present setting). Anyone else? I run Nova as my launcher...
[Asus Transformer TF700] sbdags:
Nope never seen that.

I have beta 6 booting :) Don't ask about beta 5... let's say it sleeps soundly ;)
[Asus Transformer TF700] geffasaurus:
Try activating 'show touches' in Developer Options\input, and see if you get a false screen touch (a persistent white dot) where the menus drop down (or anywhere, for that matter).

I believe it means the digitizer is stuffed, but can be worked around by mostly keeping the tab on some sort of stand, and i use bluetooth keyboard and mouse.

Zombi pop Beta 4

Installed on my ASUS TF700T 32GB,

Problems with lagging, freezing up.

Set up using your tips.

Shows only 1 cpu core, three others marked as offline. How do I fix that?

Sometimes, screen goes black and I have to reboot.
[Asus Transformer TF700] Anders Williams:
The active core thing is completely normal, the "offline" cores are in sleep mode so they don't use power when there is little load on the device, if you start something they will "wake up" so to speak.

Regarding lagging and freezing, what kernel are you running and did you do a clean install with a full wipe? Also have you have formatted the filesystem to F2FS?

I just flashed this and so far it is running better than before. Great job devs :)

But, It is being used by my kid and he complains that some og his games are lagging.

I noticed during the installation, that I could select a lower resolution.

If I dirty flash the same ROM and then select a lower resolution, would that work? And would a lower resolution make games run smoother?

I tried searching for this, but didn't see any concrete post that it would help.

I hope you guys can help me :)

VPN issues

Hello all,

I just did the 5.1 B5 update. The VPN is still not working. Could anyone check if this is a specific lollipop 5.1 issue or it is an issue with this particular ROM.

When a VPN client is connected (eg.: VPN Capsule) it seems that dns is not working. Accessing sites by name are giving timeout while load correctly using an IP Address.

Thank you
[Asus Transformer TF700] tvig0r0us:
On b6 and it's running really nicely on external. I have a question that you might find a bit, well. odd. I use google now and the search bar a pretty fair amount and I've noticed a couple of times that the search bar will be there for just a second during boot, right when the launcher loads, then it disappears. If I take the tablet from the dock and put it in portrait mode, the search bar shows back up, but disappears again when back in landscape. Is there an option anywhere to have the search bar all of the time? I know I can drag it onto a homescreen as a widget, but was hoping I could get it as it is built in so that it doesn't scroll with the home screens.

Anyhow, I'm pleased as punch with the performance of the tab otherwise. You guys have done an outstanding job with Lolipop on the tf700!! Thanks a million!

ZOMBi-POP OMNI KANG BETA 6 is really the best ever rom I have on the TF700T as it runs reasonably fast and smooth on this troubled tablet. I can't thank you enough for bringing a fresh breath of life to the TF700T.
[Asus Transformer TF700] Anders Williams:
Flashed Beta 06 this morning with Omni Kernel (wanted to try that for a while to see how it performs) so far a very smooth experience, obviously a lower benchmark score to _THAT kernel it being clocked default at 1400 MHZ but it runs very smoothly. The minimal GAPPS option to /SYSTEM is very nice on a clean install, gives a better option to choose what particular Google services you wish to use or not so personally a big fan of this option, I imagine that the "standard" google apps you choose from the Play Store afterwards then gets installed to /DATA being user apps and all and perhaps yielding a better performance on the F2FS data partition or am I getting that one wrong?
[Asus Transformer TF700] yurem:
I flashed Beta 06 few hours ago. I did wipe before flashing it.

The general estimation of this beta is about 5 :). It work's fine and stable.

There is only one question which bother me. Why after reboot the UI is not very responsive during few minutes? The CPU load during this time is less than 10-20%. What can be wrong what led to menu delays? Or it's normal behavior after loading it?
[Asus Transformer TF700] kevinthefixer:
This is quite normal. On first boot ANY new ROM takes a good long while to get up to speed, it has a lot of stuff to do (indexing etc.) If you have GAPPS installed you will find Play Store searching and downloading updates on each boot, disable automatic updates to fix that and you should find the tablet much more responsive.
[Asus Transformer TF700] _that:
Most likely I/O load. Using Cool Tool (from the Play Store) you can watch all kinds of performance stats in a tiny overlay window.
[Asus Transformer TF700] steffenbakke:

[Asus Transformer TF700] bradslinux:
Like many of the issues we see with this tab, I think most of the "lag,wait" during any normal operations that we see is because the less than crappy eMMC. It is just VERY SLOW STORAGE.

mmcqd/0 process has state 'D' during few minutes (maybe 5) !!!

According to the linux process statuses

D uninterruptible sleep (usually IO)

Thank you for response, yes it looks like it's IO issue.... During start up processes applications are loading their data from eMMC memory in background. That's makes it unusable during this period...

Have been using beta 6 all day today and browsing hard with it. Usually doing that tends to bind things up after while... lock-ups and the like. Not so far here. I'll do some youtube stuff later on to push things a bit. Oh, I installed internal with sbdags default settings which sure makes the whole install a one or two click deal. Can't thank sbdags, josh, and the other maniacs enough.

Agreed, this ROM ROCKS! I now have it installed both internal and external. It runs very smoothly so far on external. Both are using _that's 11.6 kernel. Lets face it, this is as good as it gets turning our sow's ear of a tablet into a silk purse.
