[Q] Black Screen Brick / Android Logo - Different than the others - Galaxy Tab 2 Q&A, Help & Troubleshooting

A pretty girl here in Zambia found out I know a bit about technology and brought me her Tab 2 GT3100.
Upon Power or USB insertion it boots to the 2nd Android Screen, and that's where it sits over and over again.
Upon trying to enter Recovery Mode - I get the fallen android with the stomach open.
Upon trying to enter Download mode, well, I can't.
I've managed to get an adb connection off and on upon bootup and can even get a logcat.
I cannot enter download mode via adb reboot download.
I can get access to the root filesystem via adb shell - and just for fun, I deleted contents of /dalvik-cache /cache and many 3rd party apps in /data
Still, the unit doesn't want to boot.
Any idea on this one? Is there a way that it can be reflashed via an SD Card? Can I push an image via ADB? ADB shell?
If I can get this to work, my days might just become brighter.

[Q] Screen Going Black after ATT logo Lag Fix

i installed the lag fix on my phone today and after rebooting the screen is black it makes the boot up sounds but nothing follows. the bottom buttons work and light up, it connects via adb but i cannot access SU mode.
i also did the adb shell to allow non market apps to be installed and the funny thing is i cannot access clockworkmod recovery.
Can someone help me boot up into clockworkmod recovery when i boot up vol+and vol- it takes me to the orginal recovery.
Which rom are/were you running? I897UCJF6/JH2, or an I9000 variant?
Which lagfix did you use?

try selecting reload packages in the stock recovery, for me that takes me into clockwork
I'd also be interested in a potential fix for this issue. I have a vibrant, however my co-worker has the captivate, and hit this same issue. Can't get SU via ADB. Can boot into recovery, and download mode, but would prefer to get back into the OS without reflashing if possible. He used the .bat file provided for RyanZA's lag fix. I'm not sure which version. He's also running the original stock Captivate firmware.
Do your SD cards mount when plugged into a computer?
Can you access /sdcard via adb shell?

Yep!
Both /sdcard and /sdcard/sd mount and are accessible via adb shell. I'm assuming that I can't run su as it depends on the "allow" button being clicked through superuser.apk. I of course can't click that without a working screen
I'm wondering if a version of su that doesn't use superuser.apk would allow me to get in there and undo the lagfix.
Well if you knew the exact lagfix version and type you used, you might be able to get that packaged into an update.zip that would remove the fix for you... albeit, if you're not 100% certain, it could wax all your application data.
If it was RyanZA/Tatuyama/Zilch/Myself tweaking the lag fix, it's very dependent on *which* version it was. But, I might be able to whip a removal tool.

[Q] How bad did I brick my Kyros 7005??

Okay, where to start.. I think I have bricked my phone pretty good.
Here is the approximate list of things that happened.
I wanted to try to update to froyo, so I downloaded z4root, worked beautifully
Followed all the directions to install clockwork mod (including reading far enough ahead to find out the one in the directions was for the 7015, but gave the link for the 7005 version later) - Worked like a charm
BACKED UP SYSTEM as instructed
Then here is where things went south. I attempted to install the Cyanogen Mod froyo based. I followed the directions, including backing up softmac and wpa_supplicant files. And it would not start up. I could get it into recovery mode but not to start fully. I tried doing the restore, it couldn't mount the SD Card where the backup was. Being knowledgeable enough to dangerous in Linux, I used ADB Shell and tried various things to try to find out where the SD Card or recovery image failed. I had also been trying to locate FWDN as I saw people had done fixes with that, but I couldn't get it to load in FWDN "Mode". I figured if I could replace the recovery program on there that doesn't work with the one that does, it should in theory allow me to reboot into the correct recovery mode and let me pull the files from my SD Card. After about 15 minutes of shuffling around, I ended up mounting the \system folder where I found a file called recovery. Looked to be the right size. So I made a modified batch file that would instruct it to load from that folder.
After that mistake, all of the sudden, the vtc driver that I had installed did see the unit. I was like Joy! Joy! I fired up fwdn but since I didn't have the original files that it "liked" I used an lk.rom, but I think it wasn't from an X5A but from a lonpad. Now I don't even get COBY on the screen.
But wait, I'm even more dangerous. I got the hardware ID that it's currently using on the USB bus, edited first the vtc ini file to see if I can reload a different rom. It detects it, but FWDN gives me "bad boot" error or something like that. But I'm a trooper, if I'm gonna kill it, I'm gonna kill it good. I change the SDK/ADB driver to recognize the device. And it seems to recognize it. Then I went to try "fastboot flash recovery recovery.x5ag.img " which I had NEVER been able get the unit into fastboot mode, and it goes through and does it. Then I do a fastboot reboot to see if I can get it to come up in recovery mode, but I can't.
Then the final bright idea comes up on me.. Hey, I have the backup from SD card, what if I zip it up, call it update.zip, and do a fastboot update?
Now ADB can make some kind of connection to it, but when I try to shell I get:
- exec '/system/bin/sh' failed: No such file or directory (2) -
ADB State always reports device or unknown never bootloader
ADB remount comes back with remount failed: Invalid argument
ADB push into the / or /system folders (in an attempt to push a copy of sh there) fails saying read only file system
ADB push to /sys comes back with failed to copy: No such file or directory
So, that's where I am.. I think I really really REALLY bricked this thing... although the fact that I can still ADB to it leaves some shimmer of hope.
Thanks,
Joe
can u get into the boot loader at all? If so you are not Bricked you will just need to reinstall the entire system using fast boot. You may be able to restore the default OS using an update.zip file. It may be named something different for your device. All you do with that is place it on the root of the SD card and when the bootloader boots it finds the file and flashes the phone.
I can't get fastboot to recognize the device, it goes right to the ADB bridge. Where I can run some limited ADB commands that are recognized.. If I could get it to start up in fastboot mode, that would likely solve the issue, provided I can get the correct working update.zip file, rather than me trying to fudge one from the clockworkmod backup.
do you have any hardware buttons on device? turning on with volume up or down (or back) gives you differing USB ID's to device manager - obviously you want fastboot mode. (use device manager on ADB Bridge (Details) to get your ID - i think its DEED for fastboot and D00D for fwdn)
otherwise... you can force boot a new bootrom. It's what I did on my telechips device. Find tcboot.rom - put it in the same directory as fwdn
1. Open your device
2. Unsolder your battery + terminal
3. While turning on the device, place a short - screwdriver/pin etc - across pins 7/8 of the NAND chip (for 5 seconds)
4. FWDN should bring up a message about flashing bootrom
5. Reboot (and resolder battery cable)
Note: this obviously is pretty hardcore - but i went from brick, to black screen brick, to full restore via this method.

[Q] Velocity CRUZ T103 (PT701) bricked

Oh I am hoping someone here can help me out here. I just got this tablet, and tried to do the Froyo update, only to find out (too late) that this model is different and not up-gradable to the 2.2. After screwing around a bit with it, not sure what happened, but now the entire system is gone.
It boots to the Cruz logo, and sits there. ADB recognizes it, but I have no shell access, and when I do a ADB ls /system it lists only 2 files, with random numbers.
ADB remount - FAILS
ADB reboot fastboot - FAILS (just reboots it)
ADB reboot recovery - gets to recovery (in ADB devices) but tablet is blank, but no sh access
Vol + & power do nothing.
Vol - & power do nothing
While attached to my PC (Win7-64) and hit the reset and Vol -, it shows up as JZ4760 USB Boot, but Windows REFUSES to let me install any drivers for it. (Got the USBToolKit, but even after turning off driver signing, it still says they're not signed and refuses to load them)
I got the 2.0 firmware (default) so now what I need it a way to push the img files to the tab (hopefully)
Any ideas, or is this thing really a neat little brick now?
Thanks
No one?? Come on guys...I've been on this site for a long time, and have seen some of you pull out a brick and make a phone out of it again. LOL
I'm thinking if I can just get fastboot to load somehow on the tablet, I could issue commands from my PC to "push" the image files back over.
Question is: how do I get fastboot to get onto the tablet to load into???
I would like a copy of your firmware if still available for the cruz of course impossible to find as site is no longer hosted

[TOOL] ADB Data Recovery (recover data from a phone with broken screen)

**UPDATE**
NEW VERSION
THIS RELIES ON ADB COMMANDS, SO IF YOU DO NOT HAVE USB DEBUGGING TURNED ON, OR A CUSTOM RECOVERY TO BOOT TO, THEN IT WILL NOT BE AS SIMPLE AS JUST RUNING THE PROGRAM.
Another user was having issues because he had an emulator installed, so I updated the file to give you the choice between an emulator, or device. I intend to update further to allow you to check for and select an individual device, that will come soon..
----------------------------------------------------------------------------------------------------------------
Recently my Galaxy s2's screen smashed, and, after replacing it with a GS4, i realized that many of my pictures were stuck on the internal sd card of the GS2. Being unable to turn on mass storage mode, I made a very simple tool that makes using adb pull a simple, painless process, even for the most computer illiterate of android users. Hope this helps if anyone needs it.
For anyone having issues...
If you had not previously activated USB Debugging, there are several steps you need to follow in order to enable ADB
SCREEN WORKING TOUCH BROKEN NO CUSTOM RECOVERY​first, if you can see your screen, and have access to an otg cable, plug a mouse in to the otg cable, and the otg cable into the phone. Use the mouse to enable USB debugging, or to transfer files.
HOW TO ENABLE USB DEBUGGING
SCREEN WORKING TOUCH BROKEN WITH CUSTOM RECOVERY​boot to your custom recovery ADB commands will work here. (usually hold vol- + pwr)
HOW TO BOOT TO RECOVERY
Once in custom recovery, connect the device to the PC.
open CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)
adb devices
The result should be something like
List of devices attached
051a4dd5 recovery
^^this number will be different for you
if you get a result on ADB devices, then you can use the program
SCREEN BROKEN TOUCH BROKEN WITH CUSTOM RECOVERY​boot to your custom recovery ADB commands will work here. (usually hold vol- + pwr)
HOW TO BOOT TO RECOVERY
Once in custom recovery, connect the device to the PC.
open CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)
adb devices
The result should be something like
List of devices attached
051a4dd5 recovery
^^this number will be different for you
if you get a result on ADB devices, then you can use the program
SCREEN BROKEN TOUCH BROKEN NO CUSTOM RECOVERY​now things get complicated...
*The following is paraphrased from this site
1. download the custom recovery image for your device. Copy the recovery image to a convenient location on your computer, preferably with a short path. We will be placing it on the C Drive directly (not in any folder) and using that in the next steps.
Note: The recovery image should have .img extension. If it is in a zip file, extract the .img file from it.
I recommend clockwork mod non touch from this page
2. Power your device off and reboot your device to FASTBOOT or DOWNLOAD MODE depending on which type of device you have.
(most devices are fastboot, SAMSUNG typically uses DOWNLOAD MODE)
how to boot to fastboot or download mode
[FASTBOOT]​3. Connect your device to your computer via USB and wait till you see the PC recognize the device
to check if your device is in fastboot and connected use CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)
fastboot devices
you will see a list of connected devices. if not, something went wrong.
4. Launch Command Prompt and type the following commands;
cd c:\android (this is your ADB path, c:\android is default)
fastboot flash recovery c:\recovery.img
5. Wait for the process to finish.
6. Turn device off then boot to your custom recovery ADB commands will work here. (usually hold vol- + pwr)
HOW TO BOOT TO RECOVERY
Once in custom recovery, connect the device to the PC.
open CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)
adb devices
The result should be something like
List of devices attached
051a4dd5 recovery
^^this number will be different for you
if you get a result on ADB devices, then you can use the program
[RECOVERY MODE (SAMSUNG)]​USE THE INSTRUCTIONS ON THIS PAGE
Once in custom recovery, connect the device to the PC.
open CMD and enter the following commands;
cd c:\android (this is your ADB path, c:\android is default)

HOPEFULLY THIS HELPS. REMEMBER TO CHECK THE FORUM PAGE FOR YOUR DEVICE IF YOU RUN INTO ISSUES. THIS ISN'T ANYTHING THE MEMBERS OF XDA HAVEN'T DONE THOUSANDS OF TIMES OVER.

Yes, when it references SD Card it means the internal "SD" storage built in to the phone, not the removable one. It should work as long as ADB can connect.
Sorry for taking so long to reply, i really hope you got your pictures back.

Have you also installed ADB, as well as this software?
I'm also having an issue - I have installed java, java SDK and ADB, so I can now run the data recovery tool. But when I do I'm getting "error:device not found" - am I missing drivers or something? I couldn't get all the way on the ADB configuration, because part of it required me to do something on the device... anyway, looks like the computer isn't recognising the the phone at the moment.
Any help very gratefully received (phone is Samsung Galaxy S2).

I have the same situation right now. Managed to make your program work then I get the "error:device not found". My phone does show up in the computer folder(albeit not in mass storage mode), but isn't that what this program was made to work around?
My phone is a LG Optimus G with a smashed glass... The LCD still displays fine, but I'm stuck at my swipe lock because the digitizer is dead.
Thank you for your help and your wonderful program.
Thanks for this app. My girlfriend broke her screen and digitizer on her Galaxy S4. She never turned USB Debugging mode and has a lock on her screen. When using your app I get the same error when I use adb by itself which is "error: closed". ADB detects my phone but any command I use in ADB or with your app I get that same error.
Do you know how to fix this? Thanks in advance.
Thanks a lot man.
dude this tool is just amazing and does exactly what it promised. I was spending sleepless nights thinking about how to recover my data from my broken galaxy nexus and now that I have it I can rest easy. Seriously can't thank you enough for this. Just joined xda to thank you buddy.:laugh::fingers-crossed:
Getting an error "The system cannot find the path specified."
I start the recovery tool, set eh adb path successfully, and then I get this error. If I try running the recovery to pull the DCIM library I get this:
"error: device not found"
What can I do?
Thanks!
Either way this is an amazing tool, seeing how it helped some people already. :good:
Hi, Seem to have the same problem as many others, Device not found. I cant change to MTP mode on my LG G2.
I hope someone can find a solution to this problem.
Program seems amazing doh.
Hello,
This is really a great tool ! I was wondering if you could add the possibility to recover the external sd card aswell.
Device not found
Tried to recover a Samsung Galaxy S3 mini with a broken screen
I installed adb and RecoverData, run it and then get a "device not found error"
What can I do?
Amazing app. thank you so much :good:

Please help to unbrick

Hi,
I am looking for some help as I did something stupid...
I came across some posting that explained that the moto has an unused partition under /cache that could be used for the dalvik-cache.
So I tried to move the dalvik-cache there and link /data/dalvik-cache to this new location.
Now the problem is that I get an "unfortunately the location-service has stopped" message all the time that makes the device unusuable (as soon as I press ok the same warning appears again).
When I try to boot into recovery I get a "dead android robot".
I can however access the device via adb, unfortunately I am not able to get a root shell. My device is rooted, but su in an adb-shell just hangs.
If I could only get a root-shell I could undo my changes and hopefully my device will work again, but I have to idea on what to try...
Can anone help me here?

The dead android bot is normal for stock recovery, if you didn't install a custom one. You can always flash a custom recovery using fastboot, and wipe the dalvik-cache and regular caches. Or, in the "dead android bot" screen, you can press the Vol+ key for about 15 secs, then tap the Power button, then scroll using the Vol buttons to something that says wipe cache. You might have to wipe dalvik-cache as well, if you can. I forget where the options are, since I haven't used the stock recovery in so long, sorry!
Ok, I managed to get beyond the "dead android" and from the menu I did a "wipe cache parition". That ran for some minutes, then it rebooted.
But after that I still have the same problem. The continuous "unfortunately the location-service has stopped" messages still persist.
Any other ideas?
Do you have an unlocked bootloader? If you do, the simplest solution may be to flash back to a stock ROM.

Yes my bootloader is unlocked. But I don't want to loose too much...
I believe the problem is only a permission-problem in my new /cache/dalvik-cache directory (/data/dalvik-cache now links there).
So all I would need is a way to get a root-shell (the device is rooted).
I can do a "adb shell" as normal user but that does not have the permissions to even look into /cache and for whatever reason when I type "su" I don't get an error nor do I become root but the command simply hangs...
The system as such still seems to work, e.g. my Moto still connects to my hotspot and I can ping it from there.
The even seems to be an "adb root" command, but that does not work on my adb. Is there a version of adb somewhere that would honor adb root?
Anyone with another idea on how to get a root-shell in my situation
Sorry, I don't know enough about adb commands to change the directory back to the default.
I assume you have usb debugging enabled and your computer is a trusted machine?
USB debugging is definitely enabled, whether or not I've set up my PC as trusted I don't remember.
If I didn't could that explain why I can get a shell but not as root or would you without a trusted computer not even get a shell?
Ok, issue resolved.
I've flashed clockworkmod recovery and cleared the dalvik-cache with that. That did the trick.
And moving my 300MB dalivk-cache to /cache seems to have worked and frees up memory for me, even better.
Finally the reason I could not get root in the adb shell was that when I type su in the adb-shell a superuser-request pops up on the phone that you have to acknowlege. But with constant warnings poping up I did not even see that...
Thanks for all support.
For the Developer options, look under Root access. Did you grant root access to ADB and apps?
When you type su, look at the phone's screen. Are you prompted to grant root access to ADB?
