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.
Hi guys...
I'm getting mad about this... Tried everything... I'm getting random issues while copying/moving large amount of files from/to external 64GB SD Card with EVERY file manager I tried . The error is ENOMEM. I used CM11 with Grimlock compatibility pack kernel, OmniRom with original kernel, with or without GApps installed.
An hint seems to be that even the media scanner service has problem during the boot as I can see into the logcat. It gets stat() errors on a lot of media files. :crying::crying::crying: Another strange issue is that I get those out of memory errors in the terminal emulator If I run the followinf commands
su
find / -name something
/storage/sdcard1/folder/file1.jpg: Out of memory
/storage/sdcard1/folder/file2.jpg: Out of memory
/storage/sdcard1/folder/file3.jpg: Out of memory
/storage/sdcard1/folder/file4.jpg: Out of memory
......
The SD has no problems because it works well on PC.
And the BAD thing is that I tried to put it on an Asus HD7 ME173X with Android 4.2.1 and it works flawlessly without any error. But the WORST thing is that I got the same errors on my I9000 with CM 10.2.1 stable release.
Perhaps Android > 4.3.x is the problem?
Because both omni and CM11 are based on the same sources, something maybe is corrupted in both?
Please help!
Update ....
After a flashaholic hour I reverted back to CROMi-X 5.4 with GRIMLOCK 0.8 OC Kernel.
Surprise... IT WORKS....:laugh::good::highfive:
Really strange.... As CROMIi-x is based on 4.2.1 my supposition about Android version could be true...
Well Well Well.... I was getting mad about that, but...
At last I found the real issue....:victory::victory:
My external SD is formatted as exFAT FS and seems to be a it cannot be read correctly by CM11 ROMS.:silly:
Hints of this problem could be find just googling for 'CM11' and 'exFAT'.
I have the same issue on my Samsung Galaxy S3 with CM11 and a 64 GB exFAT SD-Card. You may format it with FAT32 and no problems occur but then you will not be able to store files larger than 4 GB anymore. If you often take HD videos this is inacceptable.
Hello Everyone,

Hi guys,
I have recently purchased a htc pico and due to low money budget i cannot afford buy a new one. So i rooted it and for almost 3 weeks i am trying to install a decent rom for speed and memory increase. I know there are a lot of threads in a lot of forums of how to increase the internal memory but i have tried almost everything i guess... Mount2sd and link2sd won't work so i wish to install the stock rom but with some appropriate scripts to increase the internal memory. I only want to increase the internal memory so i need the scripts to achieve it without using the apks mentioned since i haven't had any positive results so far..
Any help appreciated

In order to use memory script on stock rom you need modified kernel with ext partition support as stock kernel is not supported.
go to this page http://forum.xda-developers.com/showthread.php?t=1754876
at bottom their are modified kernels. flash any of them.

no need to flash another kernel and i think memory increase script is already in cluded. Still you want different script try file attached below.
extract given file and place it in system/etc/init.d/ and set all permissions and reboot.

Encryption Unsuccessful Message
I tried both mod1, 2, and 3. Each time I load my rom, load the BOOT-MOD-3.zip, and then my apps (PA Gapps).
I keep getting a Encryption unsuccessful message. Also to note, during the initial boot, it only preps/installs 12-14 apps and not the 70+ that usually need to be done when I don't run the move mod.
Any ideas?

Use google to find how to create a sd-ext, there are many guides.

You need to wipe all partitions except sdcard in recovery, flash rom, gapps, then mod.
When you update rom, flash rom then mod again, that's it.
SD-ext needs to be a second primary partition formatted in ext4 (or f2fs if using cm12/cm12.1).
Note: New versions uploaded. Now supports all ivanich's ROMs (cm11,cm12,cm12.1).
@hinxnz: great mod, thx!
Working great for me, but I got 2 questions:
1) I flashed the newest cm12.1 two days ago and flashed your mod (all in SD except dalvic) afterwards. Now you uploaded a New Version compatible with all ivanich Roms. Does your update make any differences for me with cm12.1? Should I reflash?
2) You just said that the mod should be flashed after gapps, I did it the other way round. Does it matter? Got no problems so far.

It doesn't matter in what order, as long as the mod is flashed after ROM because it edits ramdisk in the kernel.
Your fine with the version you have, it will act the same. You can flash the newer version when you update your ROM.
Problem with storage size
Thanks very much for the mod.
I wanted to use "All Data excl. Dalvik-Cache" and ivanichs cm 12.1 with 4ext recovery.
I was using delta-roh method on my previous installation.
I wiped all partitions except SD card. clean install the rom, then pico gapps and then this mod. Then i install my backups with titanium backup and it started to say storage is full.
When I checked the storage it was still showin 1.15gb and it was full. But installed app size was showing 2gb. I wast able to get sms because of the storage was full.
Am I missing something with the installation method?
Thanks is advance for the replies.

Hi, I flashed boot.img (this file I unzipped from ivanich ROM 18.04.2015 ROM) from the computer with adb and flashed ivanich ROM 18.04.2015 from TWRP ivanich. It's helped.

You could use a root file explorer and check the properties of /idata or just enter code below into a terminal emulator. To enable terminal in cm12, goto developer options and enable local terminal.
Code:
df /idata

To enter recovery pull battery out, then reinsert it. Hold down volume down button while powering up device and it will enter bootloader, which then you can enter recovery by selecting recovery.
You must have a second primary partition (sd-ext) of your sdcard formatted as ext4 (or you can choose to use f2fs if using cm12 or cm12.1).
If your formatting your whole sdcard instead of shrinking your fat32 partition, then you need to create the first partition (fat32) first and then the second (ext4 or f2fs), otherwise they will be labelled wrong.
CM11 doesn't support f2fs, so if you format it as f2fs on CM11, you will get an encryption error and same goes I guess if you format a partition in ext2 or ext3 because it's not configured in fstab.
Did you try flashing ROM and then mod again, maybe it was a bad flash, it can happen.
I'm using your MOD Plus V3 with 2 f2fs partitions at the moment, which I created with GParted.
What does TWRP do when wiping sd-ext in recovery? If I need to wipe both is there any posibility without using GParted?
And similar, what is backuped by TWRP when doing a backup of sd-ext?
Multi swap
Hi there,
I love the work you've been doing on the sensation and I'm glad to still be using it 4 years on with the latest CM12.1. I have a problem with lagginess after multiple attempts to install CM12.1 and your boot mod v1.2. It seems to be an issue relating to the memory and swap, and I noticed running the cat /proc/swaps shows BOTH /dev/block/zram0 AND the data partition. Removing the zram0 by using the swapoff command speeds the phone up loads. Is there a permanent fix though to persist after reboots?
Thanks,
Keith

Hi Keith, zram shouldn't be active, my mod disables it in fstab.pyramid, found in the root directory.
I don't know why it's activated on your side, maybe an app or init.d script.
To disable it, you could use an init.d script.
Code:
#!/sbin/sh
# Disable ZRAM
swapoff /dev/block/zram0
ZRAM sorted
Thanks for the reply mate. I installed TWRP (from 4ext) and used it to reformat everything and start from scratch which sorted out the ZRAM0 issue.
After reinstalling ivanich's CM12.1 and your boot mod v1.2 it was much better. I'm still having intermittent lag and slow network speeds so I reverted to CM11 this morning (with your boot mod) to see if it was any quicker. Seems to be much quicker but the lag persists. Weirdly I get the lag most in the settings, and it bombs out sometimes. I'm wondering if it could be to do with my SD card partitions which were created in GParted, not TWRP.
If you've got any ideas of things to check I'm all ears.
Thanks for the kind support!

No worries, first try a lower swappiness value by lowering value in /cache/swap.conf, save it and then reboot.
Try 30 or 40, default is 60. See how it goes.
If you still have lag then your memory could be running very low, use an app or init.d script to raise minfree values slighty higher.
I don't think it has to do with your sd partitions, could be your sdcard is a little slow maybe.
You could probably check the partitions in twrp or gparted though.
If you sort it, post what you did :good:

Update: Blew everything away again and installed cm12.1 fresh without the SD-EXT mod and it runs fast and lag-free. Installed the sd-ext and lagginess came back. :-/
I had previously tried a fresh install with another SD partitioned by TWRP, made no difference to lagginess. Lower swappiness values seemed to have a minor difference but still laggy.
The lagginess seemed to be mostly when loading from disk. Applications in RAM seemed to run fine until they needed to load something. Downloads very slow on WiFi or 3g, titanium backup very slow too. Strange...
It would be nice to get it working but this is a tad baffling. Thanks for your kind support!

Seems to me that your sdcard is not fast enough, what make and kind of card do you have?
SDHC or SDXC and UHS-I or UHS-II
I have a Sandisk Ultra SDHC UHS-I and it's only just fast enough for this mod, I need a faster one really.
I have no issues with download speeds with wifi, not really related to mod though, could be slow at writing to sdcard.
Titanium could be slow due to slower writing speeds on sdcard too as it has to build dalvik-caches on sdcard when restoring apps.
Edit: Can you try BOOT-MOD-1.1.zip, it's the non-plus version. It would be good to know if you still experience lags with it, if you do, then sdcard is not fast enough, otherwise could be something to do with the plus version, cheers.

I'm using a Lexar 32GB class 10 SDHC, had no issues with it. I ran the A1 SD card benchmarking tool and it measured reads of 17 and writes of 11 MB/s. The internal flash reported speeds of 25MB/s read and 7MB/s write by comparison.
I'll try the BOOT-MOD v1.1 and report back...
