[Asus Transformer TF700] _that:
I can't see any interesting error messages in this log. Normally, when Android hangs at the boot animation, there are lots of errors about starting, failing to start and restarting services in the background etc. - Is this log from a fresh reboot?
[Asus Transformer TF700] kokoon:
No, that log was from the first boot after install, after it was stuck on "Starting apps." for like half an hour. The second one is also from the first boot after install but it should start sooner.
[Asus Transformer TF700] _that:
Yes, the second one includes the startup, but it still does not tell me what's wrong - it appears to wait for something.

You can try something else - get the kernel log:

adb shell dmesg > dmesg.txt

(also ideally within the first 1-2 minutes after boot start)
[Asus Transformer TF700] kokoon:
Should I install everything from scratch and grab a kernel log of the first boot again? Or just get one now, when it hangs on bootanim? Cause that whole Optimizing dialog with "Starting apps." at the end happens just the first time after installation.
[Asus Transformer TF700] kokoon:
Anyway, here's another logcat from a second boot, right from the start. And a dmesg log.
[Asus Transformer TF700] _that:
Yes, maybe it's better to reformat your card's ext4 partition and start over.
[Asus Transformer TF700] kokoon:
Cool, I'm on it!

---------- Post added at 01:44 PM ---------- Previous post was at 01:36 PM ----------

Is it weird that the freshly formatted ext4 partition already has over a gig "used", as per GParted? I think I'll give it a shot with ext2, that should work, too rigt?
[Asus Transformer TF700] _that:
Filesystem metadata uses a bit of space (inode tables).

And yes, ext2 should work too, but it is less efficient than ext4 with big files.
[Asus Transformer TF700] kokoon:
Yeah, thought so, just seemed a bit much. Anyways, I'll try with ext2 now, another thing, I forgot to mention that the first screen in aroma, where all the system info and all is listed, it always says SD-EXT Size: -1 MB and Free: -1 MB. I think another user caught this as well, I assumed it's normal... but is it really?
[Asus Transformer TF700] Astegal:
If the i/o is the same according to the benchmark, why the tf700 still lags? Does it come from a hardware issue rather than a software?

[Asus Transformer TF700] kokoon:
Well, that's odd now. Okay here's what happened:

1. formatted the ext partition to ext2

2. installed again with _that V4 kernel + D2SD(all of this is about Data2SD, so I'm not going to stress that anymore)

3. bootloop. Now I know I used that word before, but I guess I was wrong, as it wasn't "looping" back then. Now, it kept rebooting every time it tried to advance past the ASUS splash screen

4. tried the same thing again (without re-formatting ext2, just reinstall)

5. bootloop again. also, I wasn't able to get any log of that, cause nothing worked, logcat nor dmesg.

6. formatted to ext4

7. installed again (_that V4 + D2SD), for other options see my detailed post in install options above

8. works. Boots fine, I finish the wizard and switch GUI to 4.2 style. reboot.

9. works. Disable SD notification with CROMI Control. reboot.

10. works.

So right now I seem to have a working system, _that V4 + D2SD, on ext4 partition. That's all the time I can spare right now, I'll get into this later today. I also have logcats for the bootups of steps 8, 9 and 10, in case you'd like to see them.
[Asus Transformer TF700] Mikerla:
I'm having the same issue running 5.1a ET. Any suggestions how to figure out which app is causing the problem?

Update tried ET and _that V5 both have to issue, any progress getting rid of this issue on reboot?
[Asus Transformer TF700] sbdags:
It seems to be a hang over from updating from Asus 27.1 to 27.5 for the odex version. I fixed mine by flashing the deodex version then dirty flashing the odex version after one reboot. That fixed it.
[Asus Transformer TF700] jtrosky:
FYI - mine always says -1 MB as well - just assumed that was just the way it was, for whatever reason...

[MENTION=518363]sbdags[/MENTION] - is that supposed to display your MicroSD card size and free values? Should it work?

Thanks.

By the way, I *don't* use Data2SD.
[Asus Transformer TF700] _that:
Because benchmarks lie don't tell you the whole story.

Great! If it starts to behave weird again, get the logs and check for errors related to mmcblk1 in the kernel log. In that case you might have a hardware issue with the microSD card. The TF700 is known to have stability problems with some cards at UHS speeds.
[Asus Transformer TF700] sbdags:
Yeah SD-Ext should only show if you have an EXT4 partition on your external micro sd (i.e., for data2sd) however it doesn't seem to work. The reason being TWRP doesn't see the partition as available.

I'll remove it for next time as it is confusing.
[Asus Transformer TF700] hav0c:
Amazon is selling them http://www.amazon.de/Transformer-Co...ie=UTF8&qid=1382201204&sr=8-1&keywords=tf701t

I got mine from http://www.tabletcenter.nl/product/368941/new-asus-transformer-pad-tf701-dock-32-gb-gray.html

They deliver the next day in NL. Don't know about the shipping delivery time abroad but they do have them on stock.

It is a really nice tablet. The overall build quality is good and the overall speed is amazing!
[Asus Transformer TF700] sbdags:
I already tried there but they won't ship internationally this time, which is weird as they did with the TF700.

Not to worry it's out in the UK on Monday :)
[Asus Transformer TF700] woodsonmh:
Works fine. Try clearing cache or reinstalling.

[Asus Transformer TF700] sbdags:
I'm putting together some benchmarks with all the different options.

So far have tested the 4 data2sd kernels with some interesting results (I've deliberately left fsync enabled to solve the issue of data corrruption). Then I'll do the normal kernels with and without fsync. I'm using a sandisk class 10 uhs-1 sd card for data2sd btw.

I'll have them up in an hour and then I'm going to work on the kernel installer to get it up to the latest versions.

I've also spent the week trying to build a frankenrom from the TF701T build but i've been unable to get it to boot yet so that is on the back burner for now. :cowboy:
[Asus Transformer TF700] sbdags:
Right benchmarks with various kernel options:

All were taken on CROMi-X 5.1 Odex with default options at 240dpi unless otherwise stated (fsync off / on). I've used quadrant as most people understand the results - I know it's not the best and I did 3 tests each time and took the 3rd result.

Stock - fsync on - 5672

_that v4 - fsync off - 5981

_that v4 - fsync on + data2sd - 5745

_thatv5 - fsync on - 6267

_that v5 - fsync off - 6414

_that v5 - fsync on + data2sd - 6143

Hunds + ET - fsync on - 6684

Hunds + ET - fsync off - 7245

Hunds + ET - fsync on + data2sd - 6725

Hunds - fsync off - 6805

Hunds - fsync on +data2sd - 6597

So data2sd doesn't really offer that much if you keep fsync on. It does feel faster when loading large games and files. The issue is it is a bit more unstable and easier to corrupt the data partition if you have fsync off. Same risk with normal data I suppose but less likely to corrupt due to less sponteneous reboots.

Is data2sd worth it? Only if you want to use your tablet whilst downloading large files or play store updates or you are prone to corruption with fsync off. Otherwise you can achieve at least the same speed with fsync off although with a risk to corrupt your data partition eventually.
[Asus Transformer TF700] Mikerla:
Do you have to install the kernel again?
[Asus Transformer TF700] _that:
AFAIK some of the "extreme" tweaks disable the ext4 journal (which is permanent until you format /data completely or re-enable the journal) or at least mount the data partition with a less safe journaling mode and with disabled write barriers - did you replicate the same filesystem options on the microsd card?

It also depends how good the microSD card is with the I/O patterns of the specific workload in relation to the internal eMMC. Unfortunately "class X" or "UHS-I" does not tell us anything about things like small block performance and the quality of the FTL.

For me, data2sd is also valuable as a separate second environment where I can experiment with different ROMs without having to backup and restore all the time.
[Asus Transformer TF700] sbdags:
No I do not disable data journaling. I get corrupted partitions everytime I do so I remove it from the extreme tweaks.

Is it possible to move the system partition as well?
[Asus Transformer TF700] sbdags:
I did in my case, just dirty flash it choosing the exact same options.

When I did the 9 or so tests above it happened once in the flash series when I flashed _that v4, flashed it again and it went away. Very odd and no rhyme or reason to it .......
[Asus Transformer TF700] _that:
Yes, with a slightly modified Data2SD script and a microSD card with 3 partitions.

I've been to lazy to try installing a ROM directly to the card, but copying the existing one with "cp -a" (or even "dd", if the target partition is at least as big as the internal /system partition) via adb shell from the recovery is easy enough and works fine.
[Asus Transformer TF700] allan1313:
So I am a long time nova user. I was seeing people complain of lag with it which I had some. I switched to the stock 4.2 and it is very smooth. I am converted!!! Also loving gravity box and xtheme engine. I am having second thoughts about getting a new tab for Xmas now.
[Asus Transformer TF700] PolishPoet:
Nova launcher working fine here. Not a bit of lag.
[Asus Transformer TF700] awilson77584:
Did you use the Balanced or Performance settings?
[Asus Transformer TF700] LetMeKnow:
That is a very good question...:) I am looking into the new rom for the tf701t. There are a lot of libraries and modules are totally differences than the tf700. I am trying to merge some of them into the tf700 but it doesn't work very well. I need more time looking into it. Maybe, it is easier to merge them into the source code and recompile those libraries and modules..:) Any ways, I still finding a way to get them into our tf700, hahaha. About the lag question, the CPU and RAM are the big improvement over all. Maybe, the new RAM has a lot better speed comparing to the tf700. Our RAM is very slow in speed also....If I say that I don't have the lag issue when downloading apps, do you believe it? I am really don't have that problem... I still don't understand why some users have it and others are fine...I am still searching for the answer...;)

---------- Post added at 07:16 PM ---------- Previous post was at 07:04 PM ----------

Hahaha, I am working on moving the /system to my external SD using the preinit script. It does not seem to work. My next step is trying to install the rom on the external SD instead of copying the partition. [MENTION=933916]that[/MENTION], Do you have a good suggestion on this topic?:)
[Asus Transformer TF700] allan1313:
I am using the 4.2 launcher but had one question. The font of the notifications/clock is very small. Is there a way using one of the xposed modules to make it larger???
[Asus Transformer TF700] sbdags:
Sorry I should have said performance and 4.1 GUI mode.
[Asus Transformer TF700] LetMeKnow:
Are you trying to run system on external sd? I would like to try that to see if it improves the i/o speed.. Let me know if you are working on it so I can learn on the preinit script method. I tried to modify the data2sd script but it did not work on my device. I think that I must do something wrong on the modification...:(
[Asus Transformer TF700] sbdags:
No just /data

We will need another mmcblk1p3 for system on the sdcard first. Have you done that?
[Asus Transformer TF700] LetMeKnow:
No, I just want to run system on sdcard and leave the data on the internal to reduce lag. I want both system and data running in parallel because they are on separated sd cards...:)
[Asus Transformer TF700] sbdags:
I still think it will be faster if both were on the SD. There are also more reads and writes to the data partition as the whole internal SD is hosted there so data2sd makes far more sense than system2sd.
[Asus Transformer TF700] LetMeKnow:
I see your point. I am currently working on moving the system to sd so maybe you can give me some pointers....:) My first attempt is fail and I am thinking to install the rom on the sd instead of copy the system file to sd. My second thought is to copy the whole system image and write it to the sd /dev/block/mmcblk1p2 using data2sd method to see if it works...:fingers-crossed:
[Asus Transformer TF700] sbdags:
I think _that can help you more but the /system must be on an ext partition and be recognised by the kernel as /system. Therefore you should be able to use the data2sd method but I don't think it will bring any speed improvements. _that will be able to help out how to do it.

The point for me to move /system and /data to 2x ext partitions on the card is we could have 2 firmwares installed and 'swap' them by just booting without the card in. Or have a complete system on a card and use it for dev and testing etc.....
[Asus Transformer TF700] LetMeKnow:
Thanks sbdags. I will give an update how is evrything going if I am able to succeed moving the system to my sd card and improvement..:)
[Asus Transformer TF700] Ruud Westerhout:
Hi all,

I am on 5.1a, a dirty flash from 5.03 which was clean install by itself.

I am using the OC 10.6.1.14.8 Modded Kernel v5 from _that which is allowing ISO9660 drives to be connected. (No Data2SD, WW Edition, 240DPI, disable fsync, Cache2SD)

I seem unable to connect a USB drive from Samsung SE-218. Am I hoping too much to be able to connect such drive, or is it a matter of finding the solution before this is work ?

If somebody is successful in connecting such drives, please give me a hint to what combination of kernel, Cromi-X version etc. You got this working.

Last time I had to do a clean install was when I got a bootloop all of a sudden, without having flashed something new. I now have a topic I noticed just before that bootloop starting, ES Explorer is showing a lot of "cache" drives. This happened today and I can mention that I just have started using LagFix after a long time. Can this be the reason for this.

I am making a Nandroid at the moment, sure hope not to get into bootloop after that, but would like to understand for what reason ES Explorer is showing these drives.

Any solution to "clean up" ES Explorer, cleaning its internal cache does not solve this.

Last but not least I am wondering why my SD Card from my tablet is not shown most of the time. I first thought this to be a mechanical topic, too often docking, but now I notice that it is possible to watch in the Asus file manager and see the SD card card for a small moment before it is unavailable again. This happens every time I dock the keyboard back on.

These may in some way be connected with each other, would hope for some input from you guys.

regards,

Ruud
[Asus Transformer TF700] _that:
So you want /system on mmcblk1p2 and /data on internal? Then modify /system/boot/rootfs_data2sd/fstab.cardhu back to the original version from the kernel's ramdisk (with /data on mmcblk0p8 and no /datai) and only change mmcblk0p1 to mmcblk1p2. In the recovery, mount /system and then, via adb shell, mount /dev/block/mmcblk1p2 (I assume you formatted it as ext4 before) to some new directory, then cp -a /system/* /wherever/you/mounted/mmcblk1p2. Ah, and you probably should delete /system/boot/rootfs_data2sd/init.cardhu.rc.

That's exactly what I did when switching from Android 4.1 to 4.2. And with n properly prepared cards you can have n+1 firmwares, as long as they are all compatible with the same kernel zImage.

---------- Post added at 10:37 AM ---------- Previous post was at 10:32 AM ----------

Plug both ends of the cable into the correct USB ports? :)

You may need to mount it manually to access files on a disc (you din't say what you are really trying to do); I just tested that ISO9660 works with an iso image manually mounted from a remote server, since I don't have a USB drive.

cache2sd?
[Asus Transformer TF700] Ruud Westerhout:
Well yeah, I tried it two ways :

-USB cable (it is not a split cable for more power) connected to drive and to dock

-USB cable connected to drive and to tablet through Asus USB connector

What I want to do is browse the data on the drive (CD or DVD) and copy them to the tablet for local usage.

How to mount is manually ?, no experience with this.

Yes, I was using Cache2SD, if it is the culprit, how can I clean it up.

I did now just re-install the ROM by flashing again and now without ES Explorer. I installed ES Explorer from the store after that, it is now clean again.

But yet again no SD card.
[Asus Transformer TF700] sbdags:
That is how cache2sd works, it will create cache entries. I don't like how it displays them in esfile explorer but what you explained is normal behaviour. It does not affect functionality.

By disappearing SD card do you mean the notification or is the card not available in esfile explorer either as microsd? Assuming you are not talking about the dock SD.

USB sticks work fine for me. Maybe it wants too much power?
[Asus Transformer TF700] _that:
Maybe you can find an app for that. Otherwise you need a terminal app (I like jackpal's) or adb shell from a computer and some basic Linux command line skills.

From memory, the commands you need to run should be similar to:

su
mkdir /Removable/CD
mount -t iso9660 /dev/block/sr0 /Removable/CD
[Asus Transformer TF700] Ruud Westerhout:
Thanks, well yeah, it is just a "I do not like because I am afraid it means trouble" but if this is normal, than I will let it be.

I was able to reboot twice since and no bootloop occurred, so I am "calm again" :)

No actually I was talking about Dock SD. If I dock the keyboard on while I am in the Asus File Manager it shows the SD card for a little less than a second and then it is gone again. Trying to connect in that time does not give result. ES Explorer does not show the SD card at all.

It is a SanDisk mSD 64GB inside a bigger SD card, Class 10, has been working normal for a long time now.

Thanks M8, but that is probably not the way I want to go. The idea was to be able to read CD's on the fly while I am abroad. At home I have no need, my PC can read any disk needed.

Hi guys,

a quick but unusual question.

Can I just flash 3.4.7 back on the tablet if it already was using 5.1a and the respective bootloader etc.

Reason is, I just noticed that an application I really need to work, stopped working for me. It is a specialized app (Mikrokopter TT) which I need to communicated through BlueTooth with a device which communicated with my MikroKopter (let's call that a flying photocamera). After my updates to 5.0.3 and 5.1a this app stopped working and I would like to go back to seriously to check what the reason is. If 3.4.7 is not allowed, what would be a good and stable version to return to for trying (which is allowed).

Ruud
[Asus Transformer TF700] jtrosky:
I think you mis-understood what [MENTION=4878287]_that[/MENTION] was saying. You don't need a PC to mount CDs/DVDs. I just tested and I'm still able to mount CDs/DVDs just fine on 5.0.4 (using _thats v5 kernel). Haven't upgraded to 5.1 yet, but I would assume it still works there as well.

Not sure if there is an app available, but you can easily mount them using an Android-based terminal emulator (I prefer "Better Terminal Emulator"):

su -

mkdir /Removable/cdrom

mount -t iso9660 /dev/block/sr0 /Removable/cdrom

Obviously, you can make whatever directory and mount it where you like.... Again, no PC is needed for any of this.
[Asus Transformer TF700] sbdags:
Yes you should be able to flash back. You may get some funkiness with the different way android 4.1 handles the main user so format data in TWRP and reflash if it causes any issues.

Of course you could post a logcat or nag the dev of said app to get it working.
[Asus Transformer TF700] LetMeKnow:
Thanks _that. I believed that I missed the step above.. No wonder, it just booted the internal instead of the external. I checked all the files on the exterrnal and they are there, haha. I will give you a feedback when I am going back home...

Thanks,

[Asus Transformer TF700] SndChsr:
Sorry guys, noob question here. I'm currently on CROMi 4.7 and want to update to the latest version. I'm also running TWRP 2.5. Do I need to upgrade to the latest ver of TWRP in order to install CROMi 5.1 or can I use 2.5. I understand that the latest version comes with a new bootloader which is needed for cromi 5.1.

Also, if I do need to upgrade my twrp, can I just flash the downloaded zip which can be found here from currently installed twrp2.5 or do I need to use some other alternative method of installing this.

Thanks for all your help.

SndChsr
[Asus Transformer TF700] Ruud Westerhout:
Misunderstood is maybe too nice, misread is probably better.

Thanks, I think I will give this a try. Well, that is when I got my other topic solved, still do not understand what is wrong with my tablet atm.

Got two Nandroid backups which I made today and while wanting to restore TWRP says, no partition to restore. For whatever reason they are placed in yet another subdirectory W. But inside there they seem to be available, beats me how this could happen.

---------- Post added at 06:11 PM ---------- Previous post was at 06:07 PM ----------

Went back to 4.7.0 This did sound better for me, as it is still Cromi-X

Tried a dirty flash first, no result.

Tried a wipe all after that, and . . . . no result either.

I am stunned to what can be the reason here.

Problem is, that this app has not changed afaik for a long time. What did change was the firmware of the MikroKopter and I changed that back as well, also to try that way.

I lost the Sunday on this and most frustrating still do not know where I went wrong on this.
[Asus Transformer TF700] sbdags:
You can upgrade as is if you like. The version of bootloader and twrp that you are running still work on 5.1. ;)

Battery Dock potential fix

Right this might sound stupid but I want users to test this for me please.

In your Asus Customised settings when docked there is a check box under MobileDock Battery Saving Mode called Disable the wake-up function from the keyboard when the device is sleeping to save more power. Now even though that option was checked on my device I was getting hourly drain.

I unchecked it, rebooted, rechecked it, rebooted for good measure and now I haven't lost a single % on the dock or tab over the last 3 hours!

This may be the answer - maybe the setting got lost somewhere in all the upgrading and flashing, etc. Might explain why some users don't have the issue and others do..... Will leave the device docked now overnight.

Thanks to 777.300 for noticing it. Can people who have the drain bug please check if this fixes it for them too.
[Asus Transformer TF700] Goddly:
Testing now aswell
[Asus Transformer TF700] workdowg:
Testing begins...
[Asus Transformer TF700] jtrosky:
That actually makes a lot of sense, because I do recall that even though this settings was "checked", that some users still reported being able to wake their devices using the keyboard (whereas, I cannot - and I do not have the drain issue).

So basically, if someone can wake their device with the keyboard (even though this option is checked), then following [MENTION=518363]sbdags[/MENTION] recommendation will most likely correct the problem.

Nice find guys!
[Asus Transformer TF700] tiernan22:
I've been off my charger for 4 hours now and I've lost 0.5%. I rebooted while it was docked and after 2 hours I undocked and re-docked without a reboot. I'd consider this one a success.
