[Q] Unable to load, need to copy/delete files - Acer Iconia A500

After copying a lot of files to the main memory of Acer Iconia Tab A501 (Android 3.2 stock) I can't boot anymore, I think it's because there is no free space (boot progress stops at Android logo). I need a way to copy my files or delete some of them to add free space, but I don't want to reset the device!
Do you know how to do it?

I would be more concerned that you copied some corrupted files into the memory. This is probably the reason. And to locate the corrupted files would be almost impossible. Also possible you may have overwritten something the OS needs.
You might possibly get an adb connection, but I doubt it. Especially if you didn't turn USB Debugging on. And I believe the tab has to boot into the os before it can work.
Reset seems in order.

How to backup?
I need to backup several unique files from the device, reset with erasing them is not an option. Any ideas?
Please, help!

Mate, there is no way to get them if the tab won't boot...

Increase system partition size?

I am new to the EeePad and have a question...
I am working on developing and customizing some ROMs and I need a larger /system partition. How can I go about accomplishing this on my Transformer (TF101-A1)? If this is covered somewhere, a link to it will do me just fine.
Thanks for the help !

I'm not an expert, but you might be able to resize the partitions with nvflash and modding the flash.cfg file. Of course, this will only work if you have access to nvflash (b70-ish or lower serial number).
There might be some possibilities with flashing blobs via the staging partition, but I don't know if the partition table can be written that way and if that will effect the bootloader (blob.EBT). There is also a high, almost certain, brick risk if you fool around with this without access to nvflash.
You might want to check out the nvidia developers site.
Sn starts with b60 so maybe nvflash is a good possibility then.
I was successful in doing this with nvflash. Increased system from 512 mb to 768 mb.

Completely Ruined my Partitions - Need Glow Restore IMG

Hello everyone,
Yesterday evening I bought a Nook Touch with Glow, went home, backed it up, or so I thought (my backup in retrospect is only 75mb and when I restore it, it does try to boot but says "Install Failed"), then proceeded to install android with Glownooter. Most of the programs I tried to launch closed after a few seconds (though I followed the instructions and installed both .zip parts), so I was going to restore and try again.
Following the restore instructions, I blew out the entire Nook partition table in preparation and now I feel I am screwed without external help. I tried everything last night for three hours...
Could anyone upload a stock .img file for me please? I really want to use the device and don't think it would be right for me to return it to the store for an exchange because of a mistake I made. Currently my SD card has nooter on it, but last night I had CWM open with the factory.zip someone posted and tried installing that zip to no avail... I even tried the n2T-Recovery_0.2.
Thank you.

I know - I read that thread front to back last night and made no progress either.
Am I correct to assume that a backup image from someone would restore all partitions and completely solve our problem?
If so, if someone would upload an image in virgin state it would solve problems for everyone. I'm completely surprised that such an image is so elusive.
Anybody's full backup image will wipe out all your personalized data in /rom and /factory/rombackup.zip.
Generally, AFAIK, all these Nooters can screw up your Nook but not re-partition it or format it.
Make an effort to get to get your /rom back.

Is /rom an item unique to each device, or are you worried about me losing books/login information in "personalized data"? I had done nothing with my device except get past initial startup when I rooted it, so I have no personal items (books or otherwise) invested. I'm sorry if this is a silly question, but I don't understand.
Edit: Also, I used the magic (something) application to delete all partitions from the nook prior to the restore because it would not let me restore until then. If I had known my backup was invalid I would never have done that.
Attached is an image of what my restore contains. It does try to boot, but then says "Install Failed."
Note there is a romrestore.zip.

Yes, that's the idea.
But as Renate mentions, that would overwrite you /rom partition with invalid data from another device (mac address, serial, and things like that).
But in the same situation I managed to salvage my /rom partition, so if I ever install such an image from someone elses' NSTG i coudl overwrite /rom with the data from my own device.
It could be also possible to generate such an image of an NSTG and then carefully unpack, delete the most sensitive files from /rom and repack the image to share. That way no sensitive infromation would be shared/compromised.
If you happen to stumble on such an image, please let me know.
BTW, those /boot files you have, could you pack them in a zip file and send it to me or post it here in the forums? I formatted my /boot partition and I could make good use of yours (no sensitive/personal information contained in there)

I'm throwing in the towel because my /rom partition is gone and I understand all of that now. Tonight I will exchange for another (against my conscience) and make a proper backup before I do anything going forward.
In my research I found this:
search.4shared.com/postDownload/2YsbIxQJ/nook_glow_partition_files__023.html
It is all of the files except rom, and you will find the boot files in the 0 directory.
Good luck, and thanks for the help everyone.
Did you check both the p1 (/boot) and p3 (/factory) partitions to see if you had rombackup.zip?
Of course check p2 (/rom) for devconf.
Try repartitioning your Nook. You'll need CWR on an SD card with ADB or Noogie and Linux tools.

Are you sure you can't recreate the partition table and mount /rom to get access to your files?
It is explained in the thread I mentioned. If so, then it would be fairly easy to recover your device.
Be careful when returning the NSTG to B&N, some of the operations performed are not covered in the warranty and they could want to charge you....
Anyway, thanks for that pointer! I'll see if I can use it to revive my NSTG

Boot it up on CWR first, then connect the USB cable.
In Windows it should show both Removable storage and ADB on the taskbar.
Code:
adb usb
adb shell
Make sure that you have the CWR with USB ADB and not Wifi ADB.

I did successfully install ADB and the Android SDK earlier, but it is not running on my Nook under CWM and I do not know how to get it on there. The guide says "The Nook must specifically have an adbd daemon running on either WiFi or USB. The stock Nook has no adbd."
Do you know how?

You should have adb.exe somewhere. From a command window in windows (start menu, execute cmd.exe), go to the path where adb.exe resides and type "adb devices": this will tell if your nook is hooked and accessible.

I don't believe ADB is running on the nook, which is currently booted into CWM.
I do see the showing USB Mass Storage Device in device manager, but I cannot access the device as I can in noogie.
You may have the CWR running WiFi ADB (which doesn't make sense to me because you can't select AP).
If you have USB ADB running on CWR you should see on the USB in the taskbar two things, Mass Storage and ADB.

[HOWTO] Backup and Restore the System Software

The recently posted rooting method for the KFHD has been great for owners to get started on modifying the device to suit their own tastes. However, I've been a little concerned about everybody jumping in without a safety net in place. There are numerous ways that this device can get bricked. Not to put all of you into a panic, but just getting an eventual OTA update from Amazon might put some of these rooted KFHDs in jeopardy. With no custom recovery on the horizon, I think it's important to have some backup/restore plan to get these devices booting again.
Overview
This backup plan involves making raw data clones of all critical storage partitions required to boot the device. These backup archives can then be stored somewhere off the device. In case of some critical failure that prevents the device from booting normally, these archives can be used to get the device booting normally again. The restore procedure requires the use of fastboot to write the backup archives back to their proper partitions. The use of fastboot requires a working bootloader, so the device will need to boot to the bootloader's bootlogo at a minimum. If the device has a broken bootloader, this guide will not be helpful. There's currently no working procedure for repairing a broken bootloader on the 2nd generation Kindle Fire devices.
To be clear, this guide is not a backup/restore plan for your data. This is strictly for backing up the system software while in a bootable state and recovering it if some modification bricks the device. This procedure has been tested on a KFHD with system software version 7.1.1. Although I have not tested it, I'm nearly certain it will work just fine on version 7.1.5. If the KF2 has the same partition layout as the KFHD, there's no reason why it shouldn't work for that device as well. Check the post on KFHD partitions for details.
Warning: Everything below is inherently dangerous and can potentially brick your device if they are not executed properly. I have tested various aspects to the best of my ability, but you assume all responsibility for performing any of these steps.
Backup
Attached is a small shell script written to do the following…
Make a "kindlebackups" directory in /sdcard (if necessary) and make it user read/writeable.
Create gzipped backup archives of partitions 1 through 11. This includes all partitions except /cache and /data.
Make all archive files user read/writeable.
The entire backup (stock) takes up approximately 550 MB, so be sure to have at least that much available in /sdcard. Root privileges are required for the script to run properly. The best time to use this script is after step two of the published rooting procedure. That's after the second reboot of the process when the device boots up in emulation mode and allows root access for the first time. At this point, the system partition is completely stock and has not been exposed to any modifications. Even if you are past this point, the backups will still be useful for any bootable state that allows root privileges.
Download the script, unzip and place it into your current working directory where you still have access to adb, then run the following adb commands to copy the script to the Kindle Fire and prepare it to be executed...
Code:
adb push backup.sh /data/local/backup.sh
adb shell chmod 777 /data/local/backup.sh
If the device is in the process of being rooted and it has just finished rebooting for the second time...
Code:
adb shell /data/local/backup.sh
If the device has already been rooted and the su binary is available on the system...
Code:
adb shell su -c "/data/local/backup.sh"
The entire process should take approximately 5 minutes. Once the script has completed the backup, access the Kindle Fire's storage area from your computer, then copy the contents of the "kindlebackups" folder to it. The "kindlebackups" folder may be deleted after transferring to your computer.
Restore
To begin the restore procedure, the device must be put into fastboot mode. My factory cable did the job for me, so I have not explored the possibility of changing bootmodes. I developed this guide on a borrowed KFHD and I do not intend to risk the device more than necessary. Unless someone comes forward with a procedure to change bootmodes into and out of fastboot mode, I'm going to say that a factory cable is required for the time being. Besides, based on my experience with the original Kindle Fire, a broken system almost always means there is no way to change the bootmode through it. Since this procedure will very likely be used on a device that cannot boot completely or otherwise has a bad system, a factory cable will probably be the only way into fastboot mode. If you plan to root or modify your system software, invest in a factory cable.
Use the factory cable (with the device turned off, plug into the device, then the computer) to get to fastboot mode. If successful, a "fastboot" logo will take the place of the original "kindle fire" logo.
Decompress the gzipped archive to be flashed… Linux users have gunzip, Mac OS X users also have gunzip and a built-in GUI utility, and Windows users can use 7-zip. The archive must be decompressed before flashing. Skipping this step will brick your device.
Flash the image file(s) back to the device. In most cases, the device will just have to get a working system partition flashed back to it, but the others are available if they are needed. To flash the system partition...
Code:
fastboot -i 0x1949 flash system system.img
- Optionally erase the cache and/or userdata partitions if the contents of either interfere with the operation of the system software. The system will rebuild them on reboot…
Code:
fastboot -i 0x1949 erase cache
fastboot -i 0x1949 erase userdata
Once the process is complete, long-press the power button (~20 seconds) until it powers down, unplug the factory cable, and power the device back up.
Good luck.
Thanks kinfauns. I appreciate everything you did for the original kindle fire. This should help a lot of people.

I don't know if anybody has packaged the device drivers set up for this device. If nothing else, you can get the device driver installer in the "Kindle Fire Utility" for the original KF and use that.

I have not tested this and don't have a way to do so. I have some concerns about it, but I'm sure someone desperate enough will jump in and try it out. I know it's too late for some, but my suggestion is for everybody to make a backup if you can and not rely on someone else to give you archives after the fact. It's better to have your own backups.

Then you're first going to have problems getting root privileges. You need to get adb working before you attempt any part of rooting or backing up with this procedure.

This is the correct "product" reported by the KFHD. This and the product ID (0007) are the only differences between the KFHD and the original when it comes to installing the device drivers on Windows.

You can put the the images wherever you want, but you'll need to specify the path to the file. For example, if you are using Windows and put the kindlebackups directory on C:, you just need to modify the command to...
Code:
fastboot -i 0x1949 flash system C:\kindlebackups\system.img
Thank you for posting how to do this. It opens a lot of doors with at least a little security.
I made a backup earlier without a problem, then went ahead and made myself a factory cable(easy to do and worked great- old asus usb cable, 1k resistor, soldering iron, shrink tape and voila!). I feel much better about doing any mods to this device now knowing I can just flash my backup.

Req: file - System/bin/debuggerd

Tried updating from 4.2.1 to 4.2.2.
But assert check failed returning above file in results. Somehow it's been modified. No idea when and how.
Anyone running 4.2.1, could you please provide me this file.
Thanks in anticipation.

I have the exact same issue!
Here is the list of only apps with root access in my tab.
Carbon - App backup and restore, Solid explore, Stick mount, SuperSU, System tuner pro and Terminal Emulator.
Thought to seek out the culprit!

Pulled this from the 4.2.1 factory image. I seem to have got past the debuggerd error message now (though I need to revert my build.prop entirely, apparently).
Included build.prop (not yet tested) from 4.2.1 image too.
Working for me and now running 4.2.2.
At your own risk, yadda yadda, not responsible for explosions or anything less terrible, blah blah.
FWIW, I had been using Stickmount and superSU.

Thanks Now 'm on 4.2.2
In the future, If you want to pull arbitrary file(s) from Google N7 factory images, a useful skill set is to figure out how to use "sim2img" utility and loopback mounts (Windows need not apply).
Those system.img files shipped by Google are "sparse ext4 images" - they can not be directly mounted as a loopback, but that's where the "sim2img" utility comes in
The sequence goes like this:
- use sim2img to convert Google image file to regular ext4 image file
- loopback mount reg. image file
- grab whatever files you want (and check user/GRP ownership & modes)
It really is just that easy.
The "sim2img" utility is part of the android ext4_utils toolset. See this XDA thread from the Galaxy S forums for more details. (Yes the N7 system.img files from Google are also in this format.)
cheers

Big thanks.
Replacing the debuggerd file allowed twrp to load the 4.2.2 update.
Also interesting, other than titanium, the only other root app on this device is Stickmount.
Did not work for me ...
I have a N7 3G and the same message when trying to update. Replaced mine with the one from the download, no change, same error.

First of all, thanks a lot to PhoenixTank who provides me the solution. :good:
In fact to make it work, I had to change the permissions allowed on that file named "debuggerd", I checked what permissions were allowed on the original file and do the same on the copied one. I did it with ES explorer in root mod.

You'd need to backup and rename the existing debuggerd then move/copy the 4.2.1 debuggerd file to /system/bin/
Then match the permissions of the old debuggerd (I think it was 644, but I wouldn't swear by it).
The OTA zip should actually go through after that, or at least tell you about a new file you need to fix. You shouldn't lose any data, but you should probably clear cache and dalvik cache.
I did most of this via adb shell, but there are root file managers that can help. If you aren't confident about doing this and how it works, my posting was not really for you. Strongly suggest reading up until you feel confident before you start changing things around in the system partition.

Unfortunately the 3G version is different to the Wifi Nexus 7, and as you've found, the files will not work.
Since I posted, Google pulled the 4.2.1 factory images from the download site - I'm not really in a good position to help you here.
The 4.2.2 factory image might be of more use if you can't source the 3G specific files. i.e. flash the new factory image.
Had this same problem. Will try solution tomorrow morning. Probably will download the links rather than trying to extract them myself (though I may leave that for a later exercise).
Would like to note that I also use StickMount as well as SixAxis Controller, Wifi Key Recovery, AppSync and LMT Launch err.
Seems like stick mount is the common one though.

Thanks guys
Those 2 files worked.
I got past "Verifying current system" and am now on 4.2.2.
I wanted to try to get the files myself as an exercise but Google pulled the 4.2.1 images from their website.
What is weird... is that I noticed a /system/bin/debuggerd.bak file that I didn't make myself, don't know what did (though StickMount seems to be the current suspect).
The weird thing is that debuggerd and debuggerd.bak were exactly the same.

I want to do this, but I can't find the system/bin folder, what root explorer apps do you guys use?
EDIT: Used Total Commander, copied the permissions from old file to new and voilah! It worked.
No need to download build prop.
Now I am on 4.2.2
EDIT 2: Now WiFi only says SAVED and not CONNECTED.
Just want to say THANK YOU!! I've been researching this error since Friday and finally found the solution here! And yes, I too have Stickmount!

Can only recommend that you clear cache and dalvik cache. I have not experienced Wifi issues since the update.
To anyone I've helped, you are very welcome and I appreciate those thanks clicks too.

can i do the reverse ? i.e. ext4 partition back to flashable img ?
that way it would be easier to root as I just need to dump a copy of su into it then flash.
And for Windows, just get oracle virtualbox(or your favorite VM, even virtual PC should work) and boot a copy of debian

Yes. I did exactly the same thing, but for 4.2.1. Guess I need to repeat it now for 4.2.2. Note in this case "flashable" means the fastboot way (as with the Factory ROM flashes), not via custom recovery.
Uhh let's see - the script tool used for re-packing is ./mkuserimg.sh - see the links I provided above
I need some help... I'm rather noobie. Had issue with upgrading to 4.2.2 so copied the debuggerd and build.prop files over to the system/bin directory. Still failed to upgrade. Tried it again today and now the N7 will not boot up. I can see it's on but it just stops at a blank screen. I have stock 4.2.1 w/root. Stock bootloader. I'm thinking its refusing to boot because I forgot to change the file permissions on the debuggerd file but not sure how to try and fix it. Please advise...
UPDATE: Managed to flash the system partition for 4.2.2 so hoping I'm good to go. Asked this question in another post but is it necessary to update any of the other partitions?

how to recover deleted files in Nexus 4 ?

hello
all my files gone after i installed stock factory image .. is there anyway to recover them ?
AW: how to recover deleted files in Nexus 4 ?
Hello,
If the files you mean was on an external sd card, take that one directly out and use your pc to rescue the files. Google for sd card undelete. There are so many programs out there...
It's really important to keep in mind, that you can only rescue that files that sectors are not overwritten by new stuff. But you will see that by using such a software.
A good one is "runtime get data back for ntfs & fat" search for it.
And remember to push thanks if I can help you - sorry for my bad english.

You can try the Myjad Android Data Recovery to recover deleted files on Nexus 4.
Step 1: First you need to connect your Android phone to computer, just via a USB cable.
Step 2: When the program detects your Android device, press the "Scan" button to start scanning all lost data including photos, videos, audio files, etc.
Step 3: After the scanning, all the fount data are categorized by file types, you can preview the photos, click the "Recover" button to get back files one per time or in batch.

An old thread, but the app diskdigger worked very well for me with the help of coreFTP on the PC
Just Google Android Data Recovery to get a program to help you recover
If you flash the stock image, your data partition including the internal sdcard gets overwritten. That's why the recovery tools are not working.
They might only work if the filesystem gets corrupted, you accidentally delete stuff our quick format the partition - hence the data is still there but not referenced in the filesystem table anymore.
Data recovery, Nexus 4
Sad to say but if you are on Android 4.3, Build JWR66Y, Google has enabled 'TRIM' for managing data on the NAND flash drive for your nexus 4 memory, and recovering data from a TRIM enabled drive is almost impossible as of now.
Though, if you are on Android 4.2, there are some softwares to recover data but is tricky for an unrooted Device as one cannot recover data via MTP/PTP.
Hi
plz Help
I lose my data after stock flash. any way to recover??

Sorry to say this again, but if you flashed the factory image without changing the flash-all script, the answer is no. It's called "image" because it contains a mirrored image of the whole system, not just individual files. So flashing it completely overwrites your memory from first to last bit.
How recovering deleted files usually works:
When you delete a file the system just marks the place where it's stored as free. It doesn't actually delete it. So until that place is taken by another file it will still be there and can be recovered by said software. Once it gets actually overwritten it's finally gone.
Before try an recovery app named DiskDigger. If it doesn't work try the second method (with cygwin and recovery pc-app) recovery more files (follow the link below). In addition , block meemory of data partion, you can use on many differents programs of recovery (recuva, photo rec,...) to succed recovering your files.
http://forum.xda-developers.com/gal...de-internal-memory-data-recovery-yes-t1994705
the method is roughly this:
-install cygwin in c:\cygwin. Don't forget installing pv and util-unix packages
-copy adb drivers and unzipped ncat in c:\cygwin\bin.
adb drivers are in \adt-bundle-windows-x86_64-20130717\sdk\platform-tools
the link for zipped ncat: http://www.daemon.de/idisk/Apps/netcat-openbsd-cygwin/netcat-openbsd-win32-1.10.2.3.tar.gz
-follow the method describe on http://forum.xda-developers.com/gal...de-internal-memory-data-recovery-yes-t1994705. But be careful to apply these modifications:
-replace mmcblk0p12 by mmcblk0p23 in this line
/system/bin/busybox nc -l -p 5555 -e /system/bin/busybox dd if=/dev/block/mmcblk0p12
-replace nc by ncat in this line:
nc 127.0.0.1 5555 | pv -i 0.5 > mmcblk0p23.raw
for recovery program in windows, i try recuva and photo-rec. Photo-rec is better:
Select "Msft Virtual Disk".
In menu options, switch Paranoid and "Keep corrupted files" to YES
Select for partition "Unknown [Whole disk]".
Select système files ext3.
and select where in your computer the program must save the recovery file
this method is not efficient in 100%. It's better than nothing and we can keep hope.
But with luck, faith and speed (use it just after an error deleting) we will recovery your important files (photo, music, video)... perhaps
I find all thes informations on two forums:
