5.1.1 rom2sd f2fsdata omni kernel

antutu screen shots before and after

mine in fact got worse but were already unsatisfactory

i think it flashed the config of the internal which i'll try an internal flash next.

After flashing experimental patch
[Asus Transformer TF700] Tomek_Grining:
I have to say that I love the performance / graphics balance for 1600x1000 with `wm density 170`! Thanks sbdags for this wonderful workaround.
[Asus Transformer TF700] shonkin:
That is great stuff.... and I am at 1600, which is the most important bit of information. The defaults otherwise work for me. And running at that resolution seems very snappy. Gracias!
[Asus Transformer TF700] berndblb:
If you want to make changes to external /system you have to flash rom2sd1.zip first.
[Asus Transformer TF700] lj50036:
Or do you ? :D

Thx Josh
[Asus Transformer TF700] xboxster:
Sorry if this might have been answered before, but I can't figure out how to phrase this in a search.

I recently installed this ROM, and put Titanium Backup back on. I use the scheduler function for regular app backups.

However, I can't seem to change the time from the default value. There's a time, and I can select the hours, minutes, and AM/PM values, but there are no arrows to increase/decrease values.
[Asus Transformer TF700] kansasboy001:
Asus apps 2.3 with zombi pop support coming soon. This will not be the full package as you remember as I am still waiting on asus for a lollipop release for an arm based device
[Asus Transformer TF700] lj50036:
You are talking about the time in app ?

Thx Josh
[Asus Transformer TF700] _that:
I found the underlying problem. Bionic doesn't support _FILE_OFFSET_BITS=64 yet.

Either we need this:

https://android-review.googlesource.com/#/c/129970/

or we need to change all off_t to loff_t in external/ntfs-3g (or maybe use some creative macro in config.h).

---------- Post added at 05:36 PM ---------- Previous post was at 05:30 PM ----------

How do you tell the installer script in a ZIP to install stuff on the external /system partition instead?
[Asus Transformer TF700] xboxster:
Yes, in the app. Go to the schedule tab, edit or add a new schedule. The time selection portion is what I'm referring to.

I would attach an image, but I don't have 10 posts yet.
[Asus Transformer TF700] lj50036:
It cannot, but dags should have given them an aroma.....

WIth data2sd or rom2sd options .... :p
[Asus Transformer TF700] sbdags:
Yes the patch is not aroma so you need to flash rom2sd1.zip first otherwise it will install the patch to internal.
[Asus Transformer TF700] Anders Williams:
Flip the device into portrait mode, seen that "bug" on a device of mine, does not love landscape for some reason
[Asus Transformer TF700] relaps:
thank you, so here's where some of my newbness shines through. are you saying to just load multiple zips into the

"install" portion of twrp? first rom2sd then the tweak file zips? even though it defaults already to boot to sd? it probably sounds like a dumb question but i'm guessing aroma is special sauce that auto detects current configuration or asks if you want internal or external or something to that affect?
[Asus Transformer TF700] LDBAKE:
Under "Schedule", tap the " Enable" box, then you can adjust the time by clicking on the "clock face" just below the current time. Do you have the Pro version of Titanium?
[Asus Transformer TF700] DavidHart:
The leads to two questions:

- What is Bionic? The only reference that I have to that name is a Motorola Android phone.

- Is this an easy fix or could this take a while?

Thanks!!
[Asus Transformer TF700] lj50036:
I think bionic is a ref to the code here https://github.com/omnirom/android_bionic/tree/android-5.1 :D

Thx Josh
[Asus Transformer TF700] sbdags:
Yes you can multi load the zip files in TWRP first if you wish.

Aroma asks and has code to remember where the user wishes to install.

In Beta 2 the patch won't be needed so it will be business as usual with aroma :)
[Asus Transformer TF700] relaps:
ok, i reverted to internal install and flashed 5.1.1 and formatted f2fs on data

-that's kernel, 1600x1000 interactive noop 1800 and because of previous improvements 256k storage read ahead

after several hours and 4 reboots i ran antutu (notice 1920x1200)

then i ran quadrant and noticed the dpi had changed in es file explorer (mmmkay?) didn't think that much of it at first

then i flashed the tweak zip and ran antutu (notice the new resolution, strange right?)

unfortunately, my storage i/o didn't improve in benchmarks. however, this has been my most stable flash of this rom for me and the ui lag is way more acceptable than previous 4 flashes. feels like streaming media apps are much more responsive than before. so stable that i wondered what would happen if i reverted storage read ahead back to 4096k. it didn't help anything but it didn't seem to slow it down either. here's antutu after that change

i'm thankful for these results and the hard work you guys put forth so we could keep these unique and capable devices relevant. I'm really digging seeing other people's benchmarks. I'll try some other taxing tasks in the near future. I may also revert back to 1920x1200 on my rom2sd to see if it had any bearing.
[Asus Transformer TF700] xboxster:
This was the issue.

I'm guessing that Titanium on 4.X was using an older style of time selection, while this ROM uses the newer clock-shaped selector. Landscape doesn't provide enough space to place the wheel.

Is it a Titanium bug, ROM bug, or overall Lollipop bug?
[Asus Transformer TF700] sbdags:
Very odd.

I think I know what is happening with the RES though :) So you have at least helped fix that. Beta 2 will ensure that it gets set properly. ;)
[Asus Transformer TF700] Anders Williams:
All Titanium I believe, will probably be fixed in the next patch, happy it was your error and not some crazy random thing. ☺
[Asus Transformer TF700] relaps:
i reverted back to 256k storage read ahead and it is more responsive when trying to leave sluggish apps like youtube or chrome when they are having trouble loading. this is all on my current internal install mind you where i am getting antutu storage i/o scores of around 700.

is anyone using disable fsync for succesful long term use (1 month+)?

---------- Post added at 05:00 PM ---------- Previous post was at 04:03 PM ----------

256 seems to have helped me immensely in the area of responsiveness while the system is bogged down. Much thanks

---------- Post added at 05:04 PM ---------- Previous post was at 05:00 PM ----------

Should I be doing the patch at the same time as the install in twrp? Or should I wait till a full install is done? I'm trying to get it to patch the rom2sd install now.
[Asus Transformer TF700] sbdags:
It makes no difference but I recommend you flash it straight after as the installer leaves you in rom2sd mode ;)

BTW your low IO scores are because you have fsync enabled ;) I have been running fsync disabled for months with no issues.
[Asus Transformer TF700] relaps:
I'll try that next. Am I doing something wrong in this case?

Tried to flash tweak after rom2sd install and reboot. Booted into twrp and ran Rom2sd1 then tweak zip in queue. Keeps failing

[Asus Transformer TF700] berndblb:
I've been running with fsync off since CROMi - except when I was running on data2sd. That's gotta be close to 2 years now? Never had a problem
[Asus Transformer TF700] _that:
Disabling fsync off can't cause problems by itself - it only makes other problems worse: if the tablet crashes unexpectedly (on kernel or hardware level), you'll lose more data - in the worst case, the whole partition.
[Asus Transformer TF700] shonkin:
That business with manually setting (via performance > advanced in settings) the 256 read-ahead storage.... I messed about with it quite a bit and got absolutely no such results. Tried on both the 5.1.1 beta with noop set and likewise on my current 5.1 beta 6. No results at all. Is this a one-off anomaly or are various folks getting a result... and if so, how?
[Asus Transformer TF700] Sweeny:
Hi!

Thanks for your great work.

Should I really use ClockWorkMod Recovery 6.0.5.0+? Here (http://xdaforums.com/showthread.php?t=1886901) ClockworkMod Recovery 6.0.4.7 is avaiable.
[Asus Transformer TF700] nhibel:
Hello,

I have installed this rom few days ago, with ROM2SD and Omni kernel. I got a lot of reboot, even if I'm doing nothing with the tablet (Since 1 hour, I have see it reboot like 5 or 6 times)

I don't know how to do a log, so if someone can explain me, i would be happy to contribute on this thread :)

[Asus Transformer TF700] Rubister:
Fascinating, so every time I want to do a backup or a restore with TWRP I have to have this handy to flash, then do what I need in TWRP, then get out and my recovery will default on a reboot to non-data2sd mode?
[Asus Transformer TF700] fatboyinlycra:
A wipe of dalvik and cache allowed my tab to boot up OK but have reflashed as you requested and not seen any boots yet.

This reminds me of some issues people were having with cm12 on the n7000. On that device the Dev was saying it was down to the partition sizes I repartitioned my storage so that data and SD were 6 gig each and had no problems. Is a repartition possible on the infinity? I don't mind being a Guinea pig if anyone knows how it could be accomplished
[Asus Transformer TF700] shonkin:
Okay... sbdags, I've wiped the external and installed w/ fsync on and the two tweaks on the last page of the installation deselected. Running full-out at 1800ghz on f2fs and did all sorts of installs of apps and running of other apps, even while downloading email via gmail. Not a tremor so far. I'm gonna try a reboot now, which is where I often had problems before upon Zombi-Pop trying to reload. Let's see what happens. And by the way, do you want some logs of apparently well-functioning installs as well, or is that of no use? I'll post my result of the reboot as an edit in this post.

Hey, I'm back! That reboot took only around a minute. Which is a heck of a lot faster than it was any previous time. I think you're on to something.

And back again, 2 some hours later. All is still good stability wise. Playing words with friends w/ my wife while also having open other programs, email, and so on. Everything seems stable.

Antutu: 21920

Quadrant: 8190

Little things:

I would note that after repeated installs I have closely watched the "force 2d" thing, which I select during install but which is *not* selected in post-install settings, regardless of my having done so during install. I activate it and nothing bad happens. Is it activated anyway, and the check mark does nothing, or is it not activating during install?

Launcher: I installed only Omni launcher. I got Nova and Omni. But it is possible this time the web was activated, and so it quickly (would have had to be very quickly) downloaded Nova. I don't think that's the case, but can't prove it. ;)

Screen: Even though the auto-adjust on lighting is off, I'm getting some flickering w/ bright (usually white) screens. Occasional line through it, brighten/darken moments. Small stuff I don't care about except to report for y'all.
[Asus Transformer TF700] fatboyinlycra:
After 10 hours of stable running I tried upping CPU to 18000 and running antutu this caused a reboot during the 3d video test

Here's the last kmsg again

Interestingly the first boot left all sorts of funky stuff happening - no keyboard would work and the external SD card was stuck in read only with a message I had not seen before have attached a screenshot
[Asus Transformer TF700] lj50036:
Linux version 3.1.10-that10+ (dees_troy@ded1.ktechnology.net)

This would indicate that is a last_kmsg from the recovery ..... :D

Thx Josh
[Asus Transformer TF700] fatboyinlycra:
That is weird. Does that mean to say the crash didn't leave a last_kmsg in /proc?

Have done a further reboot since which fixed the SD card and keyboard issues so will try upping CPU again and run antutu to see if I can duplicate the problem
[Asus Transformer TF700] lj50036:
Was the tablet booted into android, when you ran the adb command ?

Thx Josh
[Asus Transformer TF700] fatboyinlycra:
I didn't use adb to get that last kmsg. Is in android and used es file explorer
[Asus Transformer TF700] sbdags:
The kmsg indicated it rebooted from recover the last time as lj50036 says, which is weird if it last rebooted from android. But anyway it has nothing useful to look at.

Antutu does stress things so it may mean that all 4 cores on 1800 is too much for your tab. You are OC'ing beyond what Asus intended. Note that it may well be for general usage and gaming this is not an issue as nothing stresses it like Antutu.

I will play with the tweaks today to tone them down a bit. I think I have some clues now as to what is happening.
[Asus Transformer TF700] grgmre:
sbdags, thanks for this rom. I've had a 700T for a few days now after having a TF 101 for a couple of years (timduru is a jesus to us over there). It was around an hour from when this tablet showed up at my door to when I got a full boot running ZombiPop.

While there seems to be a few rough edges running Lollipop on this hardware compared to what timduru's done with the earlier models, I look forward to the next few updates.
[Asus Transformer TF700] nate39:
I have flashify and goomanager on my tablet and neither one of them can find a twrp file to update my device. What am I doing wrong? I can flash a file on my device but I can't find a file to download other than the blob, but that is for flashing with your pc right? thanks
[Asus Transformer TF700] shonkin:
You *can* (as I do) use terminal emulator to install from comand line. From the TeamWin TWRP TF700 page:

--

Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob

Launch terminal emulator or connect to your computer and open an adb shell, then type the following:

su

dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4

Then reboot to complete installation.
[Asus Transformer TF700] LDBAKE:
http://teamw.in/project/twrp2/105

Read this.

If you use the "terminal" method, just be CERTAIN that you type in the commands correctly. Check then DOUBLECHECK your commands.

I personally prefer using the "terminal". It's just so simple to do.

(Quote from the TWRP page)...

Download the above file. Save it to the root of your /sdcard directly (internal memory only) and rename it to twrp.blob

Launch terminal emulator or connect to your computer and open an adb shell, then type the following:

su

dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4

Then reboot to complete installation.

Edit:

Sorry Shonkin, I didn't see your reply before I posted mine. Didn't mean to step on your toes :) :)
[Asus Transformer TF700] _that:
Make sure that you get at least the marked part of the command line right before you press Enter. Typos anywhere else will usually just not work without bad consequences, but the "0p4" part MUST be correct. The name after "of=" is the output file, in this case a raw partition. Replace p4 with p5 and you'll destroy your serial number and MAC address. Leave out the "p4" and you'll destroy your bootloader. So whenever you start a command line with "dd": Never press Enter before you have double checked the target partition.
[Asus Transformer TF700] Anders Williams:
It's hard to say, I have definitely seen some improvement, and a few others have reported similar, however SBDAGS reported zero results too, it can be a case of false positive but also simply different builds in terms of hardware quality, can't say for sure of course.
[Asus Transformer TF700] relaps:
On my system, on a clean boot (no programs open), the read ahead has no perceived effect. But as soon as a couple of resource hogs are open (play music, chrome, youtube) my system takes its sweet time when the home button is pressed or the program manager button. I am able to get home and change screens and pull down the top drawer a LOT faster when read ahead is set to 256k. If you have no such lag on your system then I wish you would make a video so i can see how a TF700t was supposed to work because my ui experience has not been fluid in many moons. It still runs individual programs like a champ but the ui and multitasking has suffered on mine for a long time.
[Asus Transformer TF700] XdrummerXboy:
That's how my tab acts. Individual apps are generally fine, but overall system (meaning going home or navigating settings, etc) is pretty bad.

Which Kernel seems to generate the best performance?

EDIT:

tried installing with /system and /data using f2fs. Its stuck on the penguin boot screen. Is the staging partition getting messed up after I install or something? Haven't tried using normal ext4 though, will try that later.
[Asus Transformer TF700] sbdags:
You can't set /system to f2fs
[Asus Transformer TF700] erisi:
fwiw - I have stopped using browser2ram because available memory seems to have a significant impact on task switching performance.

Gene
[Asus Transformer TF700] XdrummerXboy:
Ahh seems as though that was my issue. I figured it would be allowed since TWRP allowed it. So is only /data allowed to be f2fs?

---------- Post added at 09:34 PM ---------- Previous post was at 09:33 PM ----------

I used browser2ram for crombi 4.x (don't remember which version) and came to the consensus it did me more harm than good, I remember a lot of force closes. But I'm giving it a go with this install.
[Asus Transformer TF700] XdrummerXboy:
Nice progression of performance increases. Thanks all!

Hopefully it will have better real usage performance switching between apps and such.

1) 18453 - 5.1 Standard install, many apps

2) 22417 - 5.1.1 Clean install, no other apps.

3) 22720 - #2 plus NOOP, Performance, increase min freq to 3xx

4) 23668 - #3 plus zip file for 5.1 I/O scheduler

Quick question: I am using this ROM with ROM2SD on a 64GB microSDXC. I want to put the ROM on a 32GB card. Are there any shortcuts to do so or do I need to install everything from scratch?
[Asus Transformer TF700] kevinthefixer:
I read somewhere that there is a "dd for Windows" out there somewhere, you might try that. If you are using Linux, of course, or any other Unix system, the dd command should do it.
[Asus Transformer TF700] junx69:
Is anyone else having problems with the daydream feature not working on the latest build? Whether I have the charger in the tablet or the tablet on the dock, it wont activate. I have it enabled in settings, it will run if I chose "Start Now" but it won't run on its own. Its a minor issue, just curious if anyone is seeing the same thing.
[Asus Transformer TF700] RonnyMegane:
thanks, I'll give that a try.

another question (to everyone ;) ): Often after waking up from standby or fresh boot I get the message

"process "system" does not respond. Do you want to close it?"

. I can "wait" or "ok"....

Anyone else with this problem? What can I do?
[Asus Transformer TF700] shonkin:
You will need to post a log before anyone can really address the specifics of a system UI crash. There's an app for that called "syslog" -- it automates the process making it fairly painless. Try to take the log as soon as possible after any crash (either an error message or a full reboot, which does sometimes happen). I kept having that system UI issue myself w/ 5.1.1, which drove me back to 5.1 beta 6 for the time being.

And yes, the System UI error is fairly common. In my experience, it tends to crop up most often if I've gone for a speed higher than my tab seems to like. These days, I run at 1700 (with the _that kernel) rather than full-out 1800. And I've also opted for 1600x1000 screen resolution instead of the 1900x? default. I see smoother and quicker operation of the tab... this a subjective opinion, of course, because I can't exactly test "smoothness." Antutu scores for me are in the high 2200s to 2300, and that again is with the tab not maxxed out speed wise.

Blessings.
[Asus Transformer TF700] RonnyMegane:
i will post the log the next time I get the error. my tablet is oc'ed to 1800mhz. maybe this is the reason. maybe not, because otherwise it is stable! i use tjthe default full hd resolution.
[Asus Transformer TF700] N1FFO:
More Information

Well, my woes seem to be caused by the "external" storage protections of Lollipop. I suspect the database associating directories with apps was messed up when I had to restore my /sdcard data from a two-month old (possibly pre-Lollipop, can't remember) backup.

My problem with TitaniumBackup was apparently that its backup directory was set to one that it didn't create. Once I changed the setting to a directory that it did create, it started backing up just fine. So the "out of space" error seems to have been a lie crafted by the FUSE daemon which controls access to /sdcard (or is it /storage?) paths.

I had a similar problem with the Kindle app where it would refuse to download any books (claiming a network error, although the network was just fine in all other apps). After uninstalling it, I saw that the /storage/emulated/legacy/Android/data/com.amazon.kindle directory was still present. I attempted to delete it with ES File Explorer, but that didn't work. I attempted to rm -rf it as root in the Terminal Emulator but, even then, I got a "permission denied" error.

Then I remembered that the /storage/emulated/0 path actually resides on the /data partition, so I wondered if I could access the data via a different path. Turns out that I could, /data/media/0. That isn't mounted via FUSE, so there are only standard permission protections on it. rm -rf on the kindle directory worked just fine (as root). After that, and re-installing Kindle, I was able to download books again.

I still haven't worked out the problem with Dolphin downloads yet. I suspect the issue is more of the same. If I use Dolphin to create a directory just for downloads, it should work fine. Just haven't gotten around to that yet.

Now, just out of curiosity, do you happen know where the database which associates apps with directories resides? I'm not above some manual database manipulation to solve these problems. Sounds like fun. :D
