Boot Mod Made By Me
REMEMBER TO BACK UP YOUR ROM FIRST
information
as you all no data/media is linked to /sdcard so with my mod you can swap sdcard for external sdcard so downloads camera pictures and game data all go to extrnal sdcard the phone still shows internal as 10gb and as I use a 16gb card it shows 16gb
as you can see the phone still this storage/sdcard0 is still linked to /sdcard

Great! I need extSdCard, go outside 32GB SDCard as internal SDCard
This mod is slightly different top the earlier one I used as the earlier swapped internal for external.
This one is better for my needs. Thanks a lot
swap internal for external and init.d
We flash through CWM ? Am i correct ?
I have problem with photo gallery, after installation, I can not watch pictures. And without SD card I can not use camera.
How to uninstall your mod?

Can this be incorporated into your rom Smaberg? Would be great if it could (assuming the original dev was ok with that)
hi sir!
i like this mod! can you please show to us how did you do this? do we have to modify the kernel or just make an init.d script?
thanks a lost sir!
Hej everyone!
I have a strange problem mounting my encrypted internal SD card. Most of the time it just doesn't work after upgraing to CM 10.2 nightlies.
When looking at the table of mounted storage devices I should get this (and a couple of /dev/block/dm-x nodes):
Code:
rootfs / rootfs ro,seclabel,relatime 0 0
tmpfs /dev tmpfs rw,seclabel,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,seclabel,relatime,mode=600 0 0
none /dev/cpuctl cgroup rw,relatime,cpu 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,seclabel,relatime 0 0
selinuxfs /sys/fs/selinux selinuxfs rw,relatime 0 0
/sys/kernel/debug /sys/kernel/debug debugfs rw,relatime 0 0
none /acct cgroup rw,relatime,cpuacct 0 0
tmpfs /mnt/secure tmpfs rw,seclabel,relatime,mode=700 0 0
tmpfs /mnt/asec tmpfs rw,seclabel,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/obb tmpfs rw,seclabel,relatime,mode=755,gid=1000 0 0
tmpfs /mnt/fuse tmpfs rw,seclabel,relatime,mode=775,gid=1000 0 0
/dev/block/mtdblock4 /cache yaffs2 rw,seclabel,nosuid,nodev,relatime 0 0
/dev/block/mtdblock6 /efs yaffs2 rw,seclabel,nosuid,nodev,noatime 0 0
/dev/block/platform/s3c-sdhci.0/by-name/system /system ext4 ro,seclabel,nosuid,nodev,relatime,user_xattr,barrier=1,data=ordered 0 0
/dev/block/dm-0 /data ext4 rw,seclabel,nosuid,nodev,noatime,errors=panic,user_xattr,barrier=1,nomblk_io_submit,data=ordered 0 0
/dev/block/vold/254:1 /storage/sdcard0 vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
tmpfs /storage/sdcard0/.android_secure tmpfs ro,seclabel,relatime,size=0k,mode=000 0 0
What I get instead is all the above but neither the "/dev/block/vold/254:1" nor the "tmpfs /storage/sdcard0/" line. Also all "/dev/block/dm-x" lines, except the dm-0 line are not there.
What I have found so far is that it seems as if I have to hurry do decrypt the sd card when I boot the phone to get my sd mounted and if it fails to mount then under /dev/block I get a dm-0 device node, but no dm-1.The /dev/block/vold/254:1 node is also missing when mounting fails. This makes me think the devices are not found and thus not created at boot time.
When my sd card is mounted I also have no problem using it.
Has anyone any idea?
chnage it to MTP

Thanks, but this didn't work. My Nexus is always automatically switching back to mass storage. Also I am not sure why this would help. The SD card isn't even recognized by the phone, so how could my PC?
I screwed up a bit here. I was using the stock recovery to format my /cache partition but about 5 minutes in it froze. Figuring that something had went wrong i hard rebooted the phone and now when I boot it appears that my internal sdcard partition has disappeared.
In adb I tried to cd into /sdcard and the directory is missing entirely
Code:
/system/bin/sh: cd: /sdcard: No such file or directory
same thing here
Code:
[email protected]:/ $ cd /storage/emulated/legacy
/system/bin/sh: cd: /storage/emulated/legacy: No such file or directory
My mountpoinits show no sign of sdcard anywhere
Code:

If anyone has any suggestions I would appreciate them. I would really like to be able to recover my data from the device before I wipe it.

Here you go, just flash cache.img on this thread (method 2)
http://forum.xda-developers.com/showthread.php?t=2513701
Your data may be lost at all so, if it does not work, then use flash-all method (method 1)

Glad it's fixed. Keep that thread in the first aid kit:cyclops:
Remember - NEVER reboot your phone when it's trying to wipe. Some of these phones take an exceptionally long time to wipe depending on your recovery.
I have TF700 running Crombi-KK F2FS on data, and added the 'discard' flag to fstab.cardhu to (hopefully) ensure trim of flash memory. Is there some way to verify that the discard function is working?

The fstab,cardhu gets modified by my boot process depending upon what you chose. I intentionally remove the discard option as it cause me bootloops.
However to check if yours has persistd ( and it may have if you haven't been anywhere near data2sd or rom2sd) is run the following in a terminal
mount | grep /dev/block/*
look for the /data and you will see what options it has been mounted with, interested to see if discard has persisted and why it won't work on my device

You can't edit the fstab directly as it gets replaced by the kernel on every boot.
so go to /system/boot/print.d
Open 30fstab-f2fs in a text editor
On this line change it from
$BB sed -i '/mmcblk0p8/{;s/ext4/f2fs/;s/barrier=.,//;s/nodiratime,//;s/noauto_da_alloc,//;s/nomblk_io_submit,//;}' /fstab.cardhu
to
$BB sed -i '/mmcblk0p8/{;s/ext4/f2fs/;s/barrier=.,//;s/nodiratime/discard/;s/noauto_da_alloc,//;s/nomblk_io_submit,//;}' /fstab.cardhu
Reboot but be prepared for a bootloop that you can only fix by undoing what you just did.... Have a nandroid ready to go

Just a cautious check on syntax before I do this. Every other flag on that line is of the form: ;s/flagx,// , yet in this instance you suggest just forward slash after 'nodiratime', ending with just a forward slash instead of two forward slashes. Is this intentional or should the syntax be: //;s/nodiratime,//;s/discard,//;s/noauto_da_alloc, etc.
Although I've used linux for years (Since Red Hat 7!) and have just enough knowledge to follow instructions to edit scripts, I still don't grasp syntax very well. (Just enough to know if I get it wrong things screw up
Also, if I save a copy of the 30fstab-f2fs file to sdcard can I simply copy it back using TWRP (latest) instead of a full nandroid restore?
Sorry if these are dumb questions. Your help is greatly appreciated.

Yes it is my correct - my edit will replace nodiratime with discard Your edit will look for discard (which isn't there) and replace it with nothing
Personally I'd do a full nandroid but yes as long as you can partially recover then that single file should be ok.

Many thanks (red face here). I'll give it a try today and do the full nandroid backup just in case. Will report back the result.
Well! That was a debacle.:crying:
Changed to:
"$BB sed -i '/mmcblk0p8/{;s/ext4/f2fs/;s/barrier=.,//;s/nodiratime/discard/;s/noauto_da_alloc,//;s/nomblk_io_submit,//;}' /fstab.cardhu "
It didn't boot loop, but eventually booted into a screen which said, "Encryption Unsuccesful. Encryption was interrupted and can't complete. As a result your tablet is no longer accessible" etc....
Thank god for the nandroid! When I reflashed the nandroid, TWRP reported that it was formatting system to ext4 even though it was originally F2FS. However when I rebooted and checked in terminal it indicated that the FS on system was in fact F2FS.
# mount |grep /dev/block/mmcblk0p8
/dev/block/mmcblk0p8 /data f2fs rw,nosuid,nodev,noatime,background_gc=on,user_xattr,acl,errors=panic,active_logs=6 0 0
No idea why, but its all working again, but alas, no 'discard' option. Could this be the reason?
[email protected]:/ # fstrim -v /data
fstrim: FITRIM: Inappropriate ioctl for device
Don't know what that error means and google wasn't my friend this time.

Looks like the discard flag was just ignored? Any way to make it persist?

What is the additional partition mmcblk1p2 for data? The partition mmcblk0p8 which on my system is my data partition has been located on /datai and is ext4 on yours. How does that happen? Are you using data2sd or something?

Yes, you are correct. I am using Data2sd. I am running f2fs on my external data partition (/dev/block/mmcblk1p2) and leave my internal data partition as ext4 because it is just a backup data partition that I actually never use it.

Ah! Mystery solved then. sbdags was right then that with internal F2FS /data the discard option will bootloop, or, as in my case boot and trash the data partition requiring factory reset. Hopefully, the F2FS file system and KitKat manage garbage collection well enough without fstrim/discard as I don't want to reinstall again as ext4 at this point. Perhaps someone will make it work in the future.

Hmm, I did help one user using f2fs on internal data partition with discard flag on JB Rom. He had no issue until moving on with KK Rom. If I can have the tf700 long enough, I will test it out on the internal data so we can rule it out...
Garbage collection is to reclaim your locked up or old memory that old apps keeps holding on without using them. I believe that is what it is for but I may be wrong...
Hi everybody,
I'm trying to port a 4.4.4 rom for HTC Sensation xl wich only have an internal sdcard. The rom boot but the internal sdcard is not mounted , whatever rom i use as base. When I use a 4.4.2 rom as base, i can't acces the internal storage cause it said that the folder is missing or doesn't exist. When I use a 4.4.4 rom as base, it said that i "need more permission" and the internal storage file is empty even if i can see all the files in it from recovery.
I've try these solutions to fix the problem but none of them worked :
1) Put the base storage file in port framework-res.apk
2) Put the base vold.fstad file in system/ect/ folder
3) Take the sdcard file from base bin folder to port bin folder
when I try to see what is mounted in terminal emulator, this is what i get :
[email protected]:/ $ su
[email protected]:/ # mount

From a file manager i see that the 179:34 and fuse files are present in the rom wich doesn't mount the sdcard but i can't understand why the internal storage is missing.
For now, i really don't know how to fix the problem and i need your help.
