Apologies in advance if this is the wrong forum, there seemed to be so Samsung forums and didn't any more appropriate. If there is one more appropriate, could someone move my post to the correct one?
I have come across an old Samsung Galaxy Tab 2 which I had forgotten about, and can't get access to it. I can't remember the email that it was registered with and have no idea if I set a pin or not.
Is there any way to get access without delete the data held on the device? The unit has space for a memory card and a SIM. In fact, if I insert a sim, I can send an SMS to the device, but obviously can't read it.
Is there any way to boot the device or gain access to it from the memory card or from a connected PC?
Any help/pointers would be much appreciated/
I managed to boot up to the Android system recovery screen but am unsure about what I can do from there...
I know I don't want to select 'reboot system now' or 'wipe data/factory reset' but would be interested in what I might be able to gain using:-
apply update from ADB
apply update from external storage
wipe cache partition
apply update from cache
How would I apply an update from external storage? Or rather, where should I look for a suitable update?

Hey Guys and gals, I know this has been posted many times before but I have trolled all of the threads here with no luck
Im rooting my Galaxy 9000 because the lag is actually embarasing to the point I just factory reset it and are considering returning it to Samsung...........
I have tried the one click rooting to find the instructions seem wrong? its not the power button you push but the home? button? it then tells you to move to "re-install packages, but this is not there? the only setting related is "apply sd card update.zip"
MENU ITEMS ARE
Android system recovery (heading)
Reboot system now
Apply sd card update.zip
wipe data/factory reset
wipe cache partition
formatt internal sd card
If you do the sd card thing you get the E signature verification failed and are back to square one
I have also tried to find out how to fix the signature thing with no luck
Help please?
I have also tried the Z4 root tool with no luck it runs through but does not root the phone
With one one click tool,
I also just noticed the green screen at the start states "server not running" at the top not related? phone is in USB debugging mode but the sd card is not unmounted? this matter? putting it back to a factory reset with all my software removed makes a small amount of difference but not heaps, also running wave secure on this but with a factory reset this should not stop it?
Hi
I've just unlocked the bootloader and flashed CWM recovery. Somewhere along the way Android seems to have lost access to my SD card; the photo galley, for example, says 'no photos found', there's no music found, also superSU also cannot find SU (presumeably on SD card?).
The SD card otherwise is fine; I can mount it via USB and can access it via 'ES File Explorer'.
I dont know what to do here; I've 'fixed permissions' and wiped the Dalvik cache to see if that makes any difference but no changes.
I'm just about to do a factory reset; help please?!!!!

Hello,
For starters this should really be in the Q&A section, but before doing a factory reset mount your phone to your computer with your USB and copy all the contents off your sdcard. Then reformate your sdcard from the settings on the phone, Settings>storage>erase phone storage. The remount your phone on your computer and copy att the stuff back to your phone. If that doesnt work your going to have to a factory reset.

Ah, sorry.
Thanks. I'll try that.
Ok. Next time post in Q&A or you will get really flamed for posting in the dev section by other people, not just me.
Hopefully a mod can move it to Q&A.

As you have probably learned from the previous posts, its not acceptable to post questions in the Q&A section.
Thanks for the help. And for gently shunting this post where it should be.
Problem was eventually solved by 'Rescan SD' app. Recommended; does what it says on the tin.
I'm having trouble getting feedback, and Google is of little help. I'm sure I'm not the only person with this problem but I can't find anyone else with the answer so I'm hoping one of you has a link to my answer.
Anyways I got a GoTab 6Inch running 4.0.4
It came stock with a main partition of 400MB and an SD partition of 2.3GB.
Out of both of these partitions, the 400MB one was protected in and the 2.3GB on could be "erased" by going into the settings and then storage. So I decide to "Factory Reset" and check the "Erase SD card" box.
Well with no warning from the tablet's home page or included instruction booklets, they say nothing about what was on this "free to erase" open partition. Apparantly it had some way-important files as I now can't get into recovery menu. The 400MB partition went down to 0.00MB but somehow has 39MB reserved for apps. And the 2.3GB is empty as 2.3GB. As well as no recovery menu, you also can't format to factory settings now.
Since the main partition is 0.00MB, you can't install or update apps. Also settings can't be saved, so every app is booting up as if its the 1st time every time.
If I learned anything from my Android 1.5 guides I used to read about 4 years ago, I think I need to somehow manually root, flash a new recovery, make a partition or two, and flash a whole new kernal/OS. Can anyone help with this? Getting a new recovery and partitions working properly is of the utmost imprtance because now if something goes wrong, I cant go into recovery to unbrick a device.
hello?
Hi everyone,
Since this is purely a question about the storage of my phone I thought it wouldn't really be necessary to post this on the HTC One S boards (since it's also an old phone and those boards might be a little dead) If this belongs somewhere else I apologize and I hope a mod can move it to the right boards.
So I have a HTC One S, I use CM11 on it with TWRP 2.8.5.0 and HBOOT 2.15, not sure if that's relevant information.
The HTC One S does not have any slot for a SD card, it has 16gb of internal storage.
Here's what happened: I wanted to go into my recovery but instead accidentally hit the FACTORY RESET that's right below it in the bootloader.
It did not ask for any confirmation and immediately showed me the HTC logo which means my phone is rebooting, this is where I (probably) made the mistake to hold the power button down to try and stop the factory reset of my phone.
I realize it was risky to hit the power button in the middle of a factory reset but let's just say I slightly panicked.
So my phone boots up and everything seemed to still be the same. Nothing was reset.
But a little later I notice the internal storage is unmounted. At least I think it is, see pictures:

When in TWRP -> Mount I am unable to mount "Internal storage", it simply doesn't allow me to check it in the list.
As I try to run the TWRP backup, it shows it is unable to mount the internal storage:

I have found some instructions of how to get the storage to mount, but it involves wiping the internal storage and I wanted to try and recover my date before wiping it completely.
I've tried several recovery software but none of them even detect the disk, and Windows only goes as far as seeing a non responding "Removable Disk":

Furthermore when I try to connect it as a USB mass storage device it simply attempts but after a few minutes goes back to the "Turn on USB storage" button.

I understand it's very likely that I will have to wipe the disk to be able to use it again, but I want to be completely sure there isn't a way to recover my data first.
Thanks for reading and any help you can offer.
well ,if you are rooted you can try to recover your stuff ,with an apk called disk digger from google playstore,, but it costs money... however you can find it for free on google ... just search disk digger apk free full download...hope i helped
Thanks for the reply, apparently I cant install some app either without an internal memory including the one you mentioned.
I think my next step is going to have to be wiping everything :/ hoping my internal memory will even work after that.
Hi.
I mistakenly flashed my Android Galaxy On5 (using Odin's "AP" option) with one of the Exynos files. I saw something about "userdata" and knew immediately I had made a mistake, even though I did not load anything in the Odin "userdata" option. Why I did this probably isn't relevant, but I'm happy to provide more detail.
My question, however, is a simple one: Having done this, is it still possible to recover the user data that is no longer visible on the phone? When I reboot the phone without TWRP, it looks like it has been factory reset.
The phone is rooted, and I can see the device shares with "df". I can't see any secondary SD card based on the information I found about it sitting on top of where the SIM card is installed. I have done plenty of computer data recoveries from hard disk.. But every tool I have downloaded online for the Android seems to be polluted with malware, and I even reimaged my desktop because of all the crap I've tried.
Do you have a recommended tool for this that isn't some horrible marketing ploy? Minitool, Dr.Fone, FonePaw, and Kingoroot were all unsuccessful.
Also, if the data resides on an internal SD card, how is it formatted? I assume it is not a typical EXT or NTFS file system. Can you tell me which device I should be trying to recover from? It looks like /dev/block/mmcblk0p21.
If the internal storage is inaccessible, another thought I had was to do a block copy (with dd) onto a separate SD card, but I am unsure of whether this would provide a copy of the overwritten data, or would it actually reduce my chances of recovery.
The phone is a Samsung Galaxy On5 (SM-G550T).
Much of the data is non-critical, but some of it is unfortunately irreplaceable. Again, I'm really looking for a "yes" or "no" here, either data recovery is possible or not. And of course any suggestions on how to do it are greatly appreciated. The time it took to flash was almost instantaneous, but I also realize that flash drives are different from spinning drives in terms of how data is written and stored.
Thank you.

If you haven't any advice on how to do it, just a simple "yes" or "no" as to whether a recovery is possible would be greatly appreciated. There must be a few forum readers out there who know the answer to that question. Anyone? Bueller?

If you wiped out userdata, that means all your data is gone. I know for computers, deleting data doesn't necessary delete the data, but rather makes the space unallocated, meaning new data can be written over it. Not 100% sure if they have something similar for Android. If you have google synced with your account, you can recover most of your data that way, otherwise you might be out of luck.
