[Q] Does updating your rom require you to re-apply Data2SD zip? - Asus Transformer TF700

When a new update comes out for CROMI and you install the update, does that update require that you re-apply Data2SD or is Data2SD still on there?

I assume you will need to flash the mount2sd file so that recovery knows where to use? And then after the rom flash you will need to redo the data2sd patch so that the framework and kernel understands.

They way I interpret the question is your second one, sbdags: yes, you need to apply the CROMI patch new -- it overwrites files that the update (re?)installed that would make your 700 boot into the internal storage data store instead.

The -that3 kernel auto-detects a microSD card with a second partition and will boot into the Data2SD environment if such a card is inserted, and boot normally with the internal storage without card or with a single-partition card. The other mods to access the internal storage as sdcardi etc. must be re-applied in the ROM.

Funny thing is I only recalled that auto-detect feature in v3 of your awesome kernel earlier today -- I've been using v2 since it came out. </stupid> LOL!
I'm going to reflash later this evening and use your v3, just for convenience's sake.
@OP: _that clarified justly that if you use his v3 kernel you will not have to decide which version to get. The CROMI mod for data2sd should be reflashed after updating CROMI (and I'd advise you to flash _that's v3 afterwards!); I'm not really sure as to whether you need to flash mount2sd BEFORE flashing the CROMI update -- but it won't hurt!

I figured as much since if you're installing an updated rom or patch, you will need to install the data2sd zip.
Thanks for the info.

[Q] CROMi-X 4.4 with data2sd

I'm having issues with data2sd on CROMi-X 4.4. I can get the ROM to see my ext4 partition as internal storage under the system settings, but the problem is that the random write speeds that I get from Androbench don't reflect data2sd speeds. Random write speeds are similar to the ones for internal storage (about 0.14 average). I've had this issue with all JB 4.2 ROMs. However, when I use JB 4.1 ROMs with data2sd, they work perfectly, with CROMi 3.4 being the last ROM that I tried out. I used gparted to completely reformat my sd card (as in delete all existing partitions and create new fat32 and ext4 partitions).
Would anyone happen to know the solution? I can't find the answer anywhere in the forums....

It would seem a lot of people, myself included, have had to flash _that's data2sd mod seperately after flashing the rom. You can find it here http://forum.xda-developers.com/showpost.php?p=40522097&postcount=56
You don't need to reflash the rom or anything, just flash it over the top and you're good to go. Run androbench after you're finished and you should be getting random writes at about 0.7mb/s

I've done that already. I know for certain that the tablet is running data2sd since I see that the internal storage size is the size of my ext4.

I don't know which kernel you installed, but with my kernel you don't need any modules at all - just mount and go.

Splashtop and Power Cinema V5 on PC. Works fine. I have full control over the tab to the pc desktop. Start Power Cinema, choose Music and the Sound comes from the Tablet only, I can also browse and start an play all my Files...
Is not the perfect way, but now I will try to connect the Pad via mini-HdMI-HDMI to my Yamaha Receiver.
Also I think that was not a clean installation.
I have flshed first mod_Data2SD.zip and bevor that I have wiped Cache and Dalvik.
Than I have flashed also with perform a full wipe the new Cromi V5 and the second Kernel I have choosen.
After the Reboot, all Apps, installed in the Crome V4.7 are still there...
Maybe I have some missunderstandings about Data2SD using.
I have to read and read again.
This is not my first Android an Flash... I have flashed some HTC, Samsung, unlocked, rootet ans so on, but the Asus confused me...

Well if you had data2sd on 4.7 and updated to 5.0 then you will still see the apps. I force it to use the correct partition regardless of the mount-data2sd file being flashed....
Yes, I also think so...
But where is a possibility to format the second ext4 Partition on SDCard???
There is no way in the first flash, modData2SD and nothing by flashing the CromiX.
I only can format SDCard, but this formats only the first Partition. I have a 16 GB Class 10 UHS 1 mSD Card, one Part is 10 GB second Part is ~4 GB. If I format the SD Card, only the 4 GB will be formated.
I think, this is the beginning of all my Problems here with cifs and so on.
I have seen, that the error "No such Device or Directory" doesnt mean the path to the PC, it means the path to the mountpoint. Under mnt/cifs is nothing Named like Music aand I cant create it there, its a read only file system...
So what can I do to become a really clean installation with nothing old in it?
Have I to flash first without Data2SD Support, than maybe instal a partition Manager for Android to format the ext4 Part on SD and than flash again but now with Data2SD???

I don't understand how your card is set up. Is the Ext4 partition 4GB? That isn't really big enough.
Also if you want wipe the 4GB ext4 then you must flash the mount-data2sd first in twrp.....

Yes, but the initial formatting must be done on a Linux system (or from the command line in Android with a proper mke2fs binary).
No no, missunderstanding...
10 GB is the ext4 Partition, 4 GB ist the rest from the total 16 GB IHS 1 Class 10 mSD Card.
And I did this as well, first flash the mount Data2SD.zip file, and I also wiped there, than I reboot, Power off and go again to twrp and flash the CromiX5 with Kernel how supports Data2SD an perform a full Wipe...
Allways there are still all apps on SDCard, I cant controll it, I dont have a Linux system here...
After the flashs I have only a updated Cromi, not a new system.
First boot runs and its like before.
Is there no way to format the 10 Gb ext4 Partition? Win7 x64 and Acronis could´nt read the ext4.
ooops, I did it again...
I have seen, that I can format the ext4 with paragon partitons manager suite 11 I have installed.
Is this a conform format for this job?

A friend has done the partition and format Job for me, so how can I change this??
Can a take Paragon to create first Part ext4 10 GB and the rest 4 GB Fat32 for this job?
What a f....
Now the using of Data2SD is history.
From 7am to 1pm I have tried to format an correct the Partitionstype of my 16 GB Class 10 UHS 1 mSD Card but it was only wasting time.
I have tried these jobs with MiniTool Partitions Manager Home Edition and SD Formatter.
Here I found a german page with Infos to create a ext4 Partition:
http://www.handy-faq.de/forum/android_forum/219275-ext4_partition_erstellen.html
But the Card was useless in PC and Tablet.
Now I have a fresh Installation, without Data2SD, but all my Apps are gone and not recovered by Market Place.
So I have to flash again.
Have someone here a Link to an Howto to create ext4 10GB first Partition an the rest ~4 GB with Fat32?
I´m helpless and frustrated.
So please, give some help.

People in the Data2SD thread said that MiniTool doesn't work correctly and that you have to use a Linux-based partitioning and formatting utility, e.g. gparted.
And if you create your ext4 partition first, it won't be usable for Data2SD either. As the documentation of my Data2SD add-on says, the ext4 partition must be the second primary partition.
I'd suggest you attack one problem after the other - this thread was originally about some CIFS problems - are these fixed now?
No nothing is fixed an I have created this thread to fix the problems.
All goes hand in hand.
Without a clean installation of cromi nothing works, than all apps are still there with all the errors. If I cant instal properly correct than I have the same problems like bevor.
This all I have told ya, here in this thread.
Normaly the mount data2sd.zip has to format the ext4 partition while flashing and perform a wipe, but this was not happend. After flashing mount data2SD.zip, reboot and flashing than cromix5 with full wipe all former installed apps an accounts are still there, and so I have overtaken all old problems too.

[Q] Cromi-X and data2sd

Hi, I could use some pointers on how to get data2sd on to my tablet.
I recently flashed to my first ROM, Cromi-X 5.0.3, and it seems to work well. Now I would like to apply data2sd in addition - maybe it was stupid, I guess it would have been smoother to apply that in the same move.
Anyways, I have set up a high speed micro-SD card now, formatted according to the instructions.
Now - I am a bit confused about flashing with a kernel - can I pick a kernel from the downloaded Cromi-X 5.0.3 zip-file, and flash that without any major wiping? If not, which kernel should I pick then... ?
Thanks!

You need to partition your sd card into fat32 and ext4 as per the instructions here using gparted. Do not use minitool please:

Then reflash the rom picking a data2sd option.

Data2SD Tf700 - exact steps to do - please help!

Hi,
I used my TF700 for several month, and I am very dissatified. At the moment I use a cleanrom, without external SD. As I am allready rooted an unlocked, I am not able to send it back to my seller ...
So, my last chance to get the device a little bit faster, is to install cromi rom and use data2sd. But after reading hours in several forums, I am not sure, which steps I should do to install it and which files I actually need.
I bought a class 10 microsd card, partitioned into a fat32 and an ext4 partition.
So , whats next? (It never mind, if i loose my internal sd-card)
1. I have to flash an data2sd kernel, right ? Which one?
2. I have to wipe the sd-card?
3. Install the cromi-rom ... right? Which one? I downloaded CROMi-Xenogenesis ODEX 4.7.0_Signed.zip. Or is there a special Rom for Data2SD?
Are there any further steps?
Thanks for your help!

1) You should flash the lastest cromix rom here http://forum.xda-developers.com/showthread.php?t=2425383
2 Kernel, you have 2 choices:
a) Hund's custom kernel http://forum.xda-developers.com/showthread.php?t=2143093
b) _that modified stock kernel http://forum.xda-developers.com/showthread.php?t=2230059
3) I alway wipe everything if go from one version to the next, but from cromi v4 to cromv5 you don't have to, just verify that you have the latest bootloader mentioned here http://forum.xda-developers.com/showthread.php?t=2425383

you have to do a bit more than that:
you need to make 2 partitions on your sd-card using Gparted Live CD as explained in the data2sd thread
http://forum.xda-developers.com/showthread.php?t=1962507
first partition: formatted as FAT32
second partition: formatted as EXT2 or EXT4 (i use EXT4)
both partitions need to be primary partition.
if you don't do this right, it won't work and the kernel will likely switch to internal memory (it happened to me
i always flash the twrp zip always first before i do anything else in recovery.
i have a 64gb class 10 card, my first partition is 8GB FAT32 so i can make backups to this partition and place the ROM files so they don't get lost after wiping, the remaining 56GB is formatted as EXT4 and used as internal storage.
I use the latest cromi, _that's kernel, data2sd, fsync disabled and cache2sd turned off.
It makes the TF700 a lot more usable, but (sorry to say) it's still not the machine it should have been....
first partition: formatted as FAT32 boot flag?
second partition: formatted as EXT2 or EXT4 (i use EXT4) boot flag?

The boot flag is irrelevant. Just make sure that both are primary partitions.

Curious, if one were to have made the mistake of having both partitions created as logical vs primary - what's the best way to resolve?
Fix and reboot?
Fix and re-flash and wipe cache?
Does this require a data wipe to work?
What's the best way to validate it's working correctly post boot?
Thanks!

In gparted you can convert logical to primary. Or wipe everything and start again.
As for knowing, you'll have a /datai folder where your old apps are stored as well as a new /data folder for new stuff. First boot will act like a clean install as well.

[Q] F2FS or Data2SD?

Both? Neither? One or the other?
Going to reload my TF700, probably with CROMBi-kk to try it out. Looking to optimize web browsing/facebook/gmail etc performance. Currently on CROMi-X 5.4.

Very Fast would be good!! Format the internal memory as F2FS also, or just the sdcard?

If you use data2sd then internal /data is not used.
You only need to format mmcblk1p2 to f2fs on the card for data2sd.

if f2fs+data2sd is the faster option, how should i go about getting rid of the sd installation, just take it out and install like normal on the tablet?

I've noticed no difference between data2sd and rom2sd but f2fs allows better use of the tablet when things are downloading in the background for example.

thanks, is there a guide anywhere for moving from rom2sd to f2fs and data2sd?

Easiest way is install the latest TWRP 2.7.1.1 which has format options now for both ext4 (takes 90 mins) and f2fs (takes seconds).
You'll obviously lose everything if you format /data as f2fs so have a backup if you want to go back.
If you are using data2sd or rom2sd just remember to use the data2sd1.zip or rom2sd1.zip first to switch TWRP over to your external partitions otherwise you will be formatting internal.

If you use data2sd (or rom2sd for that matter) you are not using the internal data partition for daily operations other than storage maybe. So you can leave it alone.
First step is to backup any data from the rom2sd data partition you want to keep.
Then you have to repartition the card. For data2sd you have to have 2 partitions (not 3 as in rom2sd): one fat32, one ext4 or f2fs. Do that in Gparted and while you're at it, you can format the future data partition to f2fs.
Then flash the rom with the data2sd option and _that v10 kernel.
I would also recommend getting TWRP 2.7.1
gparted?
so do i need to use gparted to partition my sd card or can it all be done with twrp and your crombi rom?

You must use gparted There is no other way.
Thank you. I'm doing my best to read through the last 100 pages of the q&a and the Rom page.

Go to the crombi-kk thread in the dev section and see post 2 - the instructions are there on how to do it
Once you partition it the installer will then do everything else for you
Thank you I did read that one, very straight forward. I am having trouble finding a zip containing twrp 2.7.1.1 ... I currently have 2.6.3-that3 but twrp manager keeps crashing on me and does not Let me choose a device in order to upgrade.
