Hey guys,
I'm having some strange trouble with my Iconia A510 that came out of the blue. It boots up normally but after about 95 sec when just everything looks nice'n ready to use, it reboots. Except for the CWM-based recovery 6.0.1.9 and a 16 GB external µSD-card the tablet is in stock condition.
So thought, no big deal and restored the full backup, created on the very day CWM-based recovery was installed some weeks ago. But it failed!
Config says:
Error while restoring /data!
I:Can't partition non-fat: datamedia
I:Can't format unknown volume: /emmc
Does this point to some defective memory cell on the internal SD? How can it be diagnosed?
Thanks!

I had corruption in /data filesystem that produced similar behavior. A file system check and repair, followed by nandroid restore got me running again. The exact process for filesystem check and repair is a blurred memory, but it involved running adb commands (fsck?) on /dev/ something. Probably had to unmount the filesystem first.

Thanks. But the thing is and please correct me if I'm wrong:
To use ADB and to do what you suggest I need the Android up and running on my tablet. Otherwise the Win7 system I connect it to does not even see it. Mine is only up for like 10 sec before it reboots ... What do I do?
Thanks

Boot into recovery and adb should work.

No! I did just that. Windows 7 itself only sees it with an exclamation mark, i.e no drivers installed. And w/o drivers ADB does not see the tablet.

I used twrp recovery but don't know if that works differently. I suggest searching to solve the adb issue. Seems solvable.

Solvable? But how? I'm a newbie to Android/Linux but I'm pretty good with Windows. Windows will not work properly with any device w/o the proper drivers installed. Drivers for the A510 (that come wih the SDK package) need Android to be operational. That leaves me with a time window of 10-20 seconds before the A510 reboots. This is a f___ing bind!
OK, making progress: Different Windows 7 system (64bit this time) sees A510 when booted to CMV-based recovery.
But which one is the data partition I need to unmount before running e2fsck?
mount
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
/dev/block/platform/sdhci-tegra.3/by-name/CAC on /cache type ext4 (rw,nodev,noat
ime,nodiratime,user_xattr,acl,barrier=1,data=ordered)
/dev #

I'm sorry I can't give step-by-step instructions, but I encourage you to keep at it and you'll solve it.
I don't have my tablet with me to compare. But it's odd that you don't appear to have a /data filesystem. Maybe /data doesn't get mounted in recovery mode. I'd want to run mount during a successful boot to be sure to get the correct partition info, but that may be very hard to do. There must be other ways to get the info, such as the Linux /etc/fstab file, but on a quick search that Linux feature doesn't seem to translate to Android.
Some googling got me here, which shows what I would otherwise expect you to be seeing.
http://www.arturaz.net/2014/09/adventures-in-reviving-acer-a510.html
It seems to me it's a little dangerous to assume the same block name (UDA) applies to your device, but in desperation, you could try it.
More googling shows an alternative approach.
http://www.acertabletforum.com/foru...able-mount-format-data-solution-included.html
This seems to operate on the mounted filesystem, so you don't need to unmount and find the raw blocks.

Ok great. The.device name was different on my A700.
Now Reboot recovery, double check that it's not mounted and run e2fsck on the UDA file. It ran for several minutes when I did it. Then try your restore again.

OK, here's what happens: I boot into recovery, unmount
/dev/block/platform/sdhci-tegra.3/by-name/CAC on /cache
(the one file that causes panic)
and nothing to be done on
/dev/block/platform/sdhci-tegra.3/by-name/UDA /data
(which is not even mounted in recovery)
I run

2nd run is ongoing. But from the number of files being processed per battery-charge I might have to repeat this over and over again.
Isn't there another way, like formatting something to get rid of logical errors and more important to get defectice clusters (yey I know, no clusters on an SSD!) marked as such? Or delete everything in /dev/block/platform/sdhci-tegra.3/by-name/UDA?
Doesn't all this point to some erroneous SSD hardware?

How did you make out? I've been thinking and googling and learned the UDA "file" is a symbolic link to the memory blocks at /dev/block/mmcblk0p10, which is what I ran fsck on directly. If you are still stuck, try that (run -- maybe the symlink slows fsck down.
There probably is another way to solve this, but I don't know it. It would seem that laying down a new filesystem on the memory blocks would solve the problem (using mkfs or its variants) but I can't guide you there. I found one web posting where someone tried that and failed.
I still wonder what happened during my repair, e.g., are there bad memory blocks waiting to surface again, or did they get marked "bad" as in your hard drive analogy.

Hello xda hackers,first off I'd like to say this is my first post here but your forums (and forum members work) has helped a lot.
I've recently been experimenting with xfs for my "sd card" on my nexus s.
(just to see the performance difference between xfs,fat32 and ext4 on my nexus s)
I've successfully compiled mkfs.xfs for arm and I’ve successfully formatted my sdcard storage with xfs. I’ve even gotten it to mount fine in android (btw, i use a custom kernel based on netarchy's git repo). i can verify it's mounted(i've even gotten it to mount at boot because vold.fstab just wasn't working). and i can even access files on it using some file browser apps.
the problem I'm having is that all of my apps think i don't have "external storage".
I've even done setprop EXTERNAL_STORAGE_STATE mounted
camera,music,etc.... all the apps say i don't have usb/external storage.
so i just wanted your help in finding out how exactly android tells if a mount-point is external storage or not.
FYI: my nexus s doesn't really have an sd card it's an internal storage (i think nand).
here is the output of some commands in case you need it:
adb shell mount:
Code:

none /sys/kernel/debug debugfs rw,noatime 0 0
adb echo $EXTERNAL STORAGE :

/mnt/sdcard
feel free to ask me for more info. and yes I’ve googled it all over and plenty of people have tried helping me on irc. all the topics that come up is about people having their sd cards not detected.
mkfs.xfs in case anyone wants it.
oh, and I’ve attached mkfs.xfs for those of you who want to run it from your phones but don't want to compile it from the source(it took me a few hours to get around some of the compilation/cross-compilation issues).
it's 1.8Mb because it's statically linked.
nvm, i got is solved by hacking around vold. thanks for all the help...Not.

Hey everyone, I'm new to the forum, and am in need of great help
A few days ago, I bought a new tablet, the Prestigio PMP5080C Pro. It's actually a very good tablet for the price you're paying. I've only had 2 problems:
1)They don't have any settings to enable proxy (Can't connect to internet at campus).
2)Many of the 3D games show only white textures (Apparently Chainfire 3D fixes this issue).
Now to fix both of them, I need root access. And that's the biggest problem I've been having.
The device uses Android ICS (4.0.3). At first I had many problems trying to get the device recognised as anything other than a USB Mass Storage Device, but eventually got it working. After that, I tried using SuperOneClick 2.3.3, it got past step 2, but then froze on step 7. No matter what I tried, it froze there everytime. After that, I tried using UnlockRoot, and it just showed the steps (completed in like 15 seconds) and didn't give me any completed messages. After that failed, I tried using RootThat, and got this log:
Code:
adbd cannot run as root in production builds
List of devices attached
ASBSM805HCZ01234 device
adbd cannot run as root in production builds
remount failed: Operation not permitted

failed to copy 'C:\RootThat\Superuser.apk' to '/system/app/Superuser.apk': Read-only file system
Unable to chmod /system/app/Superuser.apk: No such file or directory
::Success!!::
After that failed, I read up about using Wendal's RK29xxImageTools_v2.1 to unpack and repack the firmware with superuser access. It managed to unpack the firmware file (Can see the system.img, etc) but when it tries to add the root, it gives the following error towards the end:
Code:
cramfsck: superblock magic not found
Enable root permission
The system cannot find the path specified.
The system cannot find the path specified.

chmod: cannot access `system/bin/su': No such file or directory
chmod: cannot access `system/app/Superuser.apk': No such file or directory
Unpack -- All Done
Pls input: 1-Unpack 2-Pack 3-Exit
Okay, so my first question. How do I know what filesystem /system is using? I typed in "mount" in adb shell, and I get the following:

C:\Users\Xenonification>
"/dev/block/mtdblock8 /system ext3 ro,noatime,nodiratime,barrier=0,data=ordered 0 0" Does that mean it's using the ext3? Because elsewhere I've heard that it uses cramfs, so i'm not sure
And secondly, does anyone know any other methods to root this device? I was thinking about mounting the system.img, adding the files needed for root, and then repacking the firmware. But I have no idea how to do this.
Thanks guys!
Rooted roms there: http://forum.xda-developers.com/showthread.php?t=1796067
yes it's using ext3 mount output is "device mountpoint filesystem options", you can mount it in any standard (or user-friendly if you want) linux distribution by "mount image mountpoint -o loop" as root
Btw I've tried chainfire and device didn't boot, it's very probable I did something wrong but do chainfire support opengl1.1-only devices?
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

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.

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.

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.

Hello,
Me and maybe many more people can not post in the dev thread so i post my question here.
I can not see the files of my internal memory in PC. even after i execute
mount -t vfat -o nosuid,nodev,noexec /dev/block/vold/259:0 /storage/sdcard0
Click to expand...
Click to collapse
in a ssh session with root user i can not see my files
Anybody with the same problem?
any workaround
By the way may thanks to varun for his hard work, finaly we have a decent rom for our phones!!
Update: even after I enter in ftp I can not see files in /sdcard0
so am i, i can't get root acces in internal storage using cm file explorer

Flash the file attached here. after flashing varun's camera fix
It makes your phone run the mount command automatically after every reboot, with a small delay, so vold doesn't break it again.

thanks.
With this file my phone mounts the internal SDcard and i can acess it from ssh and ftp but i can not delete files and from pc Internal storage does not apear (previosly I could see it but not the files in it)
regards
First: thanks for the great effort. CM11 is a godsend.
I'm having trouble with the storage, tho.
Evernote can't write het database
SwiftKey can't download language packs
Export from dropbox fails
Bluetooth filetransfer fails
File download in browser fails with a FC
I have flashed the zip with the fix, the storage gets mounted properly. But it seems not all apps know how to handle it.
Can it be a problem that is flashed over an older Cm version? Should I first have flashed to stock?
Almost there
For me looks like now it's working, including camera
I had to reinstall Jelly Bean ftf from sony> gain root acccess > install kernel with recovery > install varun CM11 > Gapps > reboot > install StorageWorkaround.zip > install Camera_fix.zip
Now all seems to work and I can access files from diferent sources .
Maybe it was because I install varun CM11 over Mr.Stenly CM11
regards
Look into this one..
while installing zip, I am getting this kind of error:
symlink : some symlink error
and installation gets aborted.
And when I try to reboot using CWM, the phone gets stuck on bootloop. Please help! thanks
Be careful with Internal Storage
After some strugle I can access it but I copied some files to it and instaling Apps from it failed with " an error occured analyzing the package" and I also could not copy my old fotos to respective folder in Internal

Did you flash Varun's camera fix first?
PS. Even I got the same error, but then I checked, I could access my files from galleries, file explorer. Try it.
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.

No idea why, but its all working again, but alas, no 'discard' option. Could this be the reason?

It seems to stick with the "discard" mounting flag...

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...
