[Q] Ooops - Tab's funked. Help!

P6800 running Zeta
I was browsing facebook the other night when... shaboom - everything froze. No biggie I thought, I'll just do a little reset (I was getting a few FCs here and there anyway lately) and I'll be good to go...
NOPE. It started bootlooping at the initial Samsung Galaxy Tab 7.7 screen. I'm able to enter CWM recovery and even wipe the cache and flash ZIP files, but when I try to wipe data/factory reset, wipe the Dalvik cache or restore a Nandroid backupI get a System Error. It doesn't look good.
Is there a way to fix my seemingly funked /system without losing all my internal SD card data (where my Titanium backups reside) or to recover it before a full Odin flash?

Just tried again - it reboots and goes into a loop when I try to wipe data and dalvik, and when I try to restore a previous backup it gives me "Error while restoring /system!"
Any help greatly appreciated before it becomes a $600 door stop

Do you dare to wipe the system folder and follow by flashing another ROM?

ok... try go long way... download old HC stock rom and install that... then try go to stock recovery in hc and wipe your data

Thread moved to Q & A section, post in the relevant section next time.

Do you mean via Odin? Will I lose the data on my internal SD card by doing that? Is there any way of mounting the device in its current state as external storage on my PC to copy all data before a wipe?
ZhenMing: I'm not sure what you mean, but as I wrote above I am not able to wipe the system folder.

yes you will loose your data... i can give you another advice... but do this one carefully... the reason why your device cant wipe any /system or /data is because the corrupted partition... you need to check it... follow the guide in this thread...
USE ONLY PART 3... follow the guide start from this para to check your device...
Code:
Now we are going to use e2fsck to check our new partitions for errors, but not only, it also fixes some erros and it will even for example create lost & found in /data
So let's go, we'll begin with /system. If you're still in the (parted) shell, use ctrl+c and type "adb shell", then issue the following :

Since you can go into cwm, you can mount your storage and then connect to PC to copy all you want.

But won't it downsize the int sd size, if OP tab still under warranty, better to get it fix by samsung for free and not lost any space.

Just reading the 1st post of the ZETA rom thread.
He says he is using stock Kernel.
He says every 5 lines, that you should full wipe...
without giving any sort of warning that it will eventually brick your device.

Tried that one, but it won't mount unfortunately. The external will no problem, but when I try with the internal it just... well it does nothing. It's a bummer cause all my most recent backups are on the internal. Any other way of retrieving my data short of extracting the chip?
Giving it back to Samsung sounds like the best option, but I'm worried cause it has a custom ROM and it's rooted. Anyone has experience doing that?
Also I thought full wipes were good, but you're saying they eventually brick the device? How come? I thought having a custom recovery meant it would be virtually impossible to brick my device... and the weird thing is that it happened during normal usage, not while flashing.
Anyway, my priority is obviously to get my tab working again, but retrieving my internal data is second highest. Isn't there a flashable ZIP that would copy the contents of the internal SD into an external SD card? Surely this has happened to someone before me?
Thanks for all the answers, really appreciated!

nope it wont... the 3rd stage on that thread command for just check and fix the corrupted partition... its like when we force boot windows... it will run on a little diagnostic software to check the drive... same concept.

Oh I see, Thanks for the explanation. Learn something new today.

Gotcha! Will try that one and post result - thanks!

how did your partition check go?
i'm annoyed that some partitions can be corrupted randomly even doing some mundane stuffs
even on stock ICS fw, i encountered DATA corruption by just deleting a contact
i guess you have softbrick..
here is what i did:
-flash stock Honeycomb firmware using Odin
-forced tablet into stock recovery mode
-wipe Cache/Data/Factory Reset
- reboot
when your tab is working again you could backup files from your internal EMMC and you could flash ROMS from there

Thanks for that. I haven't tried anything yet as I'm away till Weds, but I will then and let you know. So you're saying by flashing stock HC via Odin and wiping/resetting everything through stock recovery I won't lose my internal storage data?

that's what i experienced..but i could not guarantee that it will be the same for your device
i noticed that because old folder are not deleted when i rebooted, but i haven't checked if the system folders are cleared
to have a clean reflash i also format/sdcard on recovery..but don't do this on stocl ICS recovery since you might risk increasing the damage
try to format via odin the Honeycomb fw first [don't put PIT file neither enable Repartion, just normal flash]
then force it to enter recovery mode when it bootloops after reset
you might fix your device this way if it has softbrick
just resort to using PIT/repartition as your last option

Again I would not recommend repartition when tab still under warranty. Repartition the last resort only if the tab is without warranty after failing all other alternatives.

After a full hangup, your stock hc is your first step out of the dark!
Best of luck

Ok I'm gonna do it. There are dozens of versions of HC for the 6800 though, can I just pick any or do I need to find out what it was running out of the box? Mine came from Singapore.

[Q] Data On My Internal Storage?

Hi guys, this is my first post on this forum ( Actually I have benn here for a long time without account )
Alright, This is my problem, I usually flash back to stock by RUU, my Pico has over 100MB free space. A few days ago, I flashed the same RUU, but this time I have 70MB space only, I have cleaned all partitions by recovery and flash again, still.
Oh wait, I just use Disk Usage and check the storage, it's say there are some data(not system) on the internal storage, wow.
Does anyone have ideas?
My Pico cid is Taiwan(621), so I flash TW RUU.
Thanks

before flashing, did you wipe system partition too?

yeah, I did, everything wiped before flash back by RUU, actually before this, I never wipe by myself but has no problems,

I know that and it's convenience, but this smartphone now is just my secondary phone.
And for a odd reason, I prefer not to creat a partition on my SD card, just like to keep it simple and clean.
Looks like I'm stubborn...

[Q] Issues with KatKiss 4.3.1_027 on TF101

Good morning-
I have a TF101 (with keyboard) running KatKiss 4.3.1_027 and gapps 4.3_20130914. Everything was fine until yesterday morning when I lost network connectivity and decided to reboot (this happens from time to time). Unfortunately, now my tablet won't boot. I get the splash screen with the swirling colored circles, but nothing more.
I tried booting to TWRP (v2.6.3.0 if it matters) and flashed KK and gapps again (including wipes as instructed). This time, it got to an "Upgrading Android" screen, went through my apps, but then got stuck on "Starting apps." I've given it about an hour in both situations and still nothing.
To make matters worse, my microSD slot is flaky and usually doesn't read my card. Based on what I've found, it looks like I have to use adb to push any new files to the tablet. If I boot TWRP and connect my TF to my PC (Windows 7), it tries to install "ASUS Android MTP Device" but is not successful (yellow exclamation point - "This device cannot start. (Code 10)"). I've tried downloading and installing the suite from ASUS, but that doesn't seem to help. "adb devices" doesn't list anything, so I'm stuck here as well.
Any help would be greatly appreciated. Thank you!!

Welcome to XDA!
This is what I responded to you over at TFF:
Sorry for the issues, it looks like the issue is a corrupt /data/ partition. By default "fsync" is off because this makes it faster, however it could get in a bootloop due to this speed. The fix is to flash the "fsync_on.zip" before the boot loop happens.
Once it happens, you are stuck, but there is help.
If you have TWRP 2.6.3.0, it is supposed to have USB support. Plug in a USB drive before booting to TWRP and it should be there.
To fix your issue and lose very minimal data, here is what will need to be done:
Boot to TWRP.
Backup only the /data/ partition. I would back it up to USB if possible, or if not back it up to the internal or microSD (if the microSD is playing nice).
Next (here is the leap of faith) do the wipe of the SYSTEM, CACHE, DAVLIK and DATA partitions. Do not do a FORMAT DATA, just a WIPE DATA (in the advanced section of the WIPE menu).
Now, install KatKiss and the GAPPS.
Wipe CACHE & DAVLIK.
Reboot.
Sign in to your Google account. You can have it restore apps if you want, I usually do myself, but it does not really matter.
Once it is done restoring your apps (or if you choose not to restore) open the Play Store an install Titanium Backup and the Premium Key for TiBu. You need the premium to restore from a TWRP backup.
Open TiBu and go into the Menu section, then find the option to restore from a nandroid backup. This will scan for any nandroid backups. Pick the backup to restore from and it will take a few minutes to scan the backup. Pick the apps you want to restore data and / or the app from.
Go make a coffee and wait for it to complete.
You may lose data from one or two apps, but you will have it from the rest of them. That is better than nothing.

Thank you!!
If that's all it is, then it's not as bad as I thought.

Unfortunately, this doesn't seem to be working for me. I used TWRP to power off my tablet. Then, I plugged in a USB stick into one of the ports on my keyboard, as this is the only way that I have access to a port. TWRP boots as expected, but I can't see my USB device anywhere. Am I doing something wrong? Is there a partition on the internal storage that I can use for the backup that won't get wiped by the process you outlined above?
Thanks again!!

You can use the INTERNAL storage option, just be sure that when you wipe you only wipe the DATA partition. Do not choose to FORMAT DATA.
WIPE DATA = wipes the /data/ partition without wiping /data/media/ (which is the /sdcard/ directory or INTERNAL)
FORMAT DATA = formats the entire /data/ partition.
As I said above, you can use the internal storage option but be sure to only use the wipe data option.

Just so I'm 100% clear:
Boot to TWRP
Check only "Data" from the left menu.
On the right side, "Storage: Internal Storage" is selected and nothing needs to be changed here.
Swipe to back up
Proceed with the steps in your original post.

Correct.

Success!! Thank you! Thank you! Thank you!! Two follow-ups to this:
1.) Since I was never able to get this working, is there a way to access the USB/SD card slots on the keyboard dock in TWRP? Using the internal storage is good, but if I want to wipe the whole thing (since my microSD card slot doesn't work), I would really have no way of ever being able to do this.
2.) I actually went up to 4.4.2, mostly because I could. However, I seem to have issues with the Google Play store where apps are always stuck on "Installing..." then the get installed but not really. I think I'll go back down to 4.3 unless there's a way to solve this.
Thank you again!!

[Q] [SOLVED] Impossible to free internal storage

I have an SD card of 64Gb and arround 20-25Gb of datas (including TWRP backup) but only 10Gb remain free. As you can see on the pictures, several Gb are missing. I have an idea of the cause, but no idea of the solution to free them.
I did a dual-boot on my tf700 to put lubuntu aside android. After using it a few months, I had some trouble and try to reinstall it ( I couldnt't syncronise zotero anymore because the version of firefox was to old and it was impossible to get a newer version without upgrading lubuntu and the upgrading of lubuntu was not working...) . As it was not working even after reinstalling lubuntu, I had to reinstall it a few times and I think that every times it occupied more space on my SD. As I'm not an expert, I decided to wipe and abandon my dual boot. I did a factory reset wipe (not including internal storage) and reinstall Cromi 5.4. I don't have the dual boot anymore, but it hasn't free the space....
The only idea I have left to free the space is to wipe also the internal storage... but as I don't think it will help (I may be wrong), I'm not very enclined to do it.
Have you any idea of how I can free this space?

Did the lubuntu installs create additional partitions?
Run ls -l /dev/block to see a list of yur partitions

Unlikely, but who knows.
The other possible explanation would be that the lubuntu data is stored somewhere in /data where it is not detected by the storage settings page.

Then a simple format of /data should bring it all back, right?

The command ls -l/dev/block indicate ls: Unkwown option '-/' . Aborting
But I installed Partition Table and it indicate that 81% (47Gb) of the memory is in /data (as in the screenshot attached)
I suppose that, as berndblb propose, I should format /data
What's the best ways to do it? With the option "format data" of TWRP ?

Yes, but this will erase *all* data. Erasing just the offending directory with a root-enabled file manager would be probably faster.

Yes. Remember that it takes a very long time (more than an hour) because it does a secure erase.

YES! I found it. There was a folder data/media/linux with files taking space for each time I installed lubuntu. I erased it and everything is fine now!
(Sorry for the space after "-l". My eyes saw the previous one but not this one...)
Thanks very much for the help!

[Q] How do I wipe my shield Totally??

Hey all,
I did a "factory reset / wipe all data" from within the CWM bootloader. However, there's still a load of trash remaining within the folder /sdcard, like movies, pictures and remnants of games I had installed. I figured that the reset wiped the system folder, but not the sdcard folder. This is correct?
Anyway, my question would be, how do I do a total wipe? I also want my /sdcard back to factory settings, how do I go about this?
Thanks in advance,
Noah.
PS. Some background info: I'm on rooted lollipop 5.0.1, using minimal adb and fastboot and CWM as bootloader. I've got some vague idea of what I'm doing, but mostly I just follow instructions on this forum blindly.
I did a reset because I had a bootloop at the nvidia logo. This followed after the battery got down to 1%, at wich point all kind of processes stopped by themselves. I plugged the shield and after battery was full again rebooted, yet it didn't.

Try in Settings, Backup & reset, Factora data reset.

In CWM, go to Mounts and Storage Menu and format /Data and /data/media. It'll erase the internal storage.
