[Q] File System question

I performed a Factory Reset / Wipe and was under the impression this cleared everything off the Xoom that I had added. Upon looking at the /mnt/sdcard folder I see folders of Apps that I had previously installed.
Question
Can the /mnt/sdcard be formatted ? If so how ?
Not super familiar with the whole file system setup so If this is a noob/stupid question could you please explain things for me.

There are two ways that I know of that I personally have done just in the last week or so. First you can unmount the SD card from the Xoom and place it in an Android Cell Phone, and go to settings/storage and from there unmount the card and click reformat SD card. Or you can hook the Xoom up via USB and clear it from within the PC/mac. Hope this helped.

Nope that would be for the micro USB card this is the /mint/sdcard which is part of the internal memory

Fastboot -w wipes all user data including /mnt/sdcard I lost some pictures of my dog because of it
Sent from my MB860 using xda premium

The simplest way I know of is thru the Backup/Restore options in CWM, just doing the wipes won't do it. I use the Team Rogue version of CWM tho, i don't remember off hand if it can be done in the other recovery's (i.e. Rom Managers version or the one from solarnz that is most popular).
I just, personally, like the way the menus are laid out with Team Rogue's version and not having like a dozen No's with one Yes when confirming an action, nothing against the others.

Thanks guys I will try the Fastboot -w when at home and able to use it and Team Rogue's Recovery when at work.

Its been awhile but what is the option in Team Rogue recovery I dont see one to wipe the Internal data

Does your battery provide voltage if you measure it? Could be that it somehow died

Uh oh.
Do you have handy the .zip of the ROM still? If so, open it up and look at the file /system/etc/vold.fstab if it contains:
Code:
dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.3/mmc_host /devices/platform/msm_sdcc.1/mmc_host
instead of:
Code:
dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.3/mmc_host/mmc1
Then basically what you've just done (unwittingly) is wiped the phones eMMC. It is now useless.

..
so now what is solution for it .. bro please help me it just 5 month old phone .

You can't do a thing, it's dead. You'll have to send it back to HTC and get it repaired under warranty.

I installed custom rom so is it come under warranty?

There is no evidence that you installed a custom ROM, there is no evidence of anything anymore, the phone is now completely empty.
What HTC will make of that I don't know, it could be that it's the equivalent of a dead motherboard. Some other people had the same problem after formatting the SD card, but I don't know what they did about it.
All you can do is call them and hope. Don't mention the custom ROM though, that would be silly.

hi
is there anyother way to fix it , rather go to htc care ?

What happen is the device formated the internal NAND memory so you now have no bootloader. With no bootloader your device can not boot or be flashed. The only fix I s to replace the mainboard or JTAG.

What about the unbricking project?

It's not bricked, it's unuseable, send it to htc, and 99% you will get another one (or replaced motherboard). There is no way to see that you rooted or anything.

this is similar to my phone problem... I only clean the pin connector in phone and battery and expecially in the phone i push in and out the four pin connector and repeat that for some minutes ..... sorry for my bad english i hope you understand

[APP] swapsd beta: Samsung

Tested by me on the Samsung Galaxy Exhibit only. (I'm told it works on the Galaxy W). If your device's /system/etc/vold.fstab file matches the attached original Galaxy Exhibit fstab file, it may work for you as well. Note: This app is not compatible with CyanogenMod. Root is required.
A common complaint about some Samsung Gingerbread phones is the fact that they mount the relatively small internal sd memory as /mnt/sdcard and this memory is treated as the phone's primary removable storage by some apps, ignoring the "real" removable sd card that Samsung refers to as "/mnt/sdcard/external_sd".
This simple gui allows you to swap the two so your larger "external sd" is mounted as "/mnt/sdcard/" and the smaller sd internal memory is mounted as "/mnt/sdcard/external_sd".
This is done by changing a file called vold.fstab in your phone's /etc folder. The original device vold.fstab file is backed up to /etc/vold.fstab.backup when this app first runs. Your data on /mnt/sdcard and /mnt/sdcard/external_sd is not touched in any way whatsoever. Root is required. Easy install: copy the apk file to your SD card and open with a file manager.
Please nandroid backup before testing!
If you get "Unknown Error, Contact Developer" you are more than likely not properly rooted! This app requires Superuser and Busybox to properly function!
Please note that if you've already moved existing apps to SD or existing apps have placed support files on SD, swapping mount points is not a good idea. Uninstall these apps, then reinstall after swapping.

So has anyone had success using this on the Exhibit II/4G or is it really just for the older Exhibit or am I just mis-reading the title?
I'd like to make the switch since the "internal" sd situation is rather silly and I just picked up a new SDHC card for my phone.

so the app is for swapping
and wt abt the txt ??? is it the original or the custom for swapping ??????

The fstab.txt is the original from the Galaxy Exhibit. It's attached so you can compare it to the /system/etc/vold.fstab on your phone. If the two match, this app may work for you.

So far.

Ok, a question as I learn more and more about the Galaxy Exhibit.
I am testing one, have some time to return if the coverage is not what I need, so I have installed my apps from my other phone, and just moved the SD card over, since it had some zips and apks that I wanted.
Since some of the directories exist already and are used by apps, while others have been recreated on the internal sd of the phone. My thought was to install the swapsd apk, immediately physically move all files from the internal sd to the actual sd card by activating the USB connection. Then disable USB, the swap is active, the media scanner will run, and the phone should see everything on /sdcard and the /ext_sdcard will be clean, except for what I left in the /usb_storage directory.
I tried mounting in recovery under mounts, mount usb storage, but it can only see one virtual drive and not both, whereas activating from the phone, both show.
Is that correct, or am I missing something? And obviously, in recovery, the partitions stay they same since the script is not running.

Samsung's stock recovery only sees the internal storage, not removable. ClockworkMod sees both. You can get cwm here.

I've attached a screenshot to the OP, hopefully that will help. It's pretty simple:
Root is required. Run the app, you'll see four buttons, Help, Default, Swap, Reboot.
To swap sd and external_sd press Swap.
To return to default, press Default.
Once you press either of the buttons above, press Reboot.
For instructions, press Help.

No. I misunderstood your post. To mount your /sdcard (internal) in cwm mount /sdcard. To mount your removable sd do mount /emmc.

Well, I got it done. I had to do it a little different, more lengthy, more secure. Backed up both partitions to my computer. Activated swapsd, rebooted to recovery, but could not mount both simultaneously. So I mounted the new /sdcard that is removable and moved what was backed up on the computer from the previous internal card to it. Rebooted and then cleaned up everything for duplicates. Thanks for the help again.

Copy the file to your SD card. Open it in your file manager.

SDCard and SDCard-ext wrong location

I just installed a new ROM and the SDCARD and SDCard-ext are in the wrong location. They are listed under the root director ( / ) and /storage instead of under /mnt/sdcard

Does it work? You could create a symlink. If that fixed it, put it in a script on bootup.

Does it work is a relative question. (wasn't meant to sound wise-a$$). I can access them, but apps do not see them at all. They are looking for the cards in /mnt therefor not finding them.
I changed them in /system/etc/vold.fstab but now it won't boot. The not booting is not an issue, I can fix that, but I don't know how to fix these incorrect paths/

No one else who's using this ROM is having these problems? I say either reflash, create symlinks, or choose another ROM.

From what I have read you cannot use them on FAT.
Why does editing this file not work? I fail to see how Android could do anything other than read the file, provided permissions are the same.

The internal memory is not FAT; typically, only the 1st partition on the SD card is FAT, everything else should be EXT. So, executing ln -s /storage /sd-ext should work (or wherever it's currently being mounted).

I meant the card but ln is not working.
One more thing I am going to try is an ADB pull and push. If that doesn't work I really need some community support.

Is there a good reason that you don't want to use another ROM?

Mainly speed and compatibility. I need the offline commands only available in JB. Stock ROM is dead slow and is only ICS. Other custom ROMs were also on the slow side and/or battery hogs.

So, is this right?

Well the way my phone is laid out is
System (I assume too large so they split it in two which resulted in the below SD-Card)
SD-Card
SD-Card EXT (The actual SD Card) - FAT32
I assume the System and SD-Card are standard Android partition format.

Do you use a file manager on the phone, such as ES File Explorer? Are you familiar with using adb?
Edit: Basically, I'm trying to figure out the exact path of the mounted partitions, and where they're supposed to be mounted.

They are 100% supposed to be mounted under: /mnt/sdcard and /mnt/sdcard-ext
Right now they are mounting to: /storage/sdcard and /storage/sdcard-ext
There is also an entry in under root ( /sdcard and /sdcard-ext --- For these two I am booting into stock ROM to see if they are suppose to be directly in root as well, will post up when I know)

Check the scripts in your init.d to see if one of them is mounting the sd partitions under /storage.
I suppose you could also try booting without the sd card in place, and see if those /storage directories still exist. Not sure how much that will tell you, though.

The init.d for sure says to load sdcards to /storage . (on this particular ROM only)
I will try without the sdcard as you suggested and let you know. Battery died on me, phone won't boot even when plugged in until at least 10%.

Which script is mounting the sd card to /storage? Is it part of the ROM, or is it something which the dev included in this ROM? I ask in case the ROM expects the sd card to be mounted there.
Regardless, try changing the script to link to /sdcard.

About xperia E memory

After i buy xperia e dual(the 2sims), i notice that this phone has phone memory 738mb, internal storage 2.01gb, and my sd 7.28gb(8gb).
The question is, can i put the games data file in the sd card? Because when i connect to pc, the internal and sd card will appear,
I test the tapsonic games and it dont work with the data file in sd card, but when i put in the internal the games works, but my internal only 2gb, it mean i cannot have many games =(
Any solutions?

You should try vold.fstab method instead. Its kinda smaller since im also using link2sd on my 16gb class 6. The phone memory goes over that limit because of link2sd hehe.
