Broke my screen & need to copy files HELP

I dropped my phone, and the screen now is a steady grey.Glass is fine, but just a grey screen when its on. I have insurance so getting a new phone. The problem is I have photo's and videos that I really want to keep, but cause my screen is broke, I can't mount the drive to copy it over.
How do I copy the files if I can't mount it in disk mode? Is there a way to mount the the phone storage on my PC via adb so that I can copy mile files off. They are on the phone storage so I can't just pull the SD drive and copy them. HELP!

go to setting and change the default connection type.

are you savvy with ADB?
If so, then all you need to know is what clicking pattern during bootup will get you to a position to use adb from your PC.

Clicking pattern? you can't use ADB with the screen locked. The screen is completely non fuctional. no way to do any pattern., but I did not have a lock pattern anyway. I didn't think you needed the phone unlocked like that to use adb?

No. Sorry. I ment the click pattern to booting to recovery.. I think ADB from recovery will be useful if you can explain the following:
-Are you rooted?
-What recovery do you have installed? (clockwork mod?)
-and do you have the android SDK on your pc which contains the ADB files? (this is why I asked if your experienced with ADB)

adb works while phone is locked to me. of course maybe that's because usb debugging is enabled. well anyway here are a few ways I can think of to help:
1:
adb pull /emmc/DCIM/ .
That will copy all internal pictures/videos to the location where adb is on your computer ("tools" folder). Do NOT forget the period at end of command!
2:
Get into ADB, either from normal power on, or in recovery.
adb shell
cp -r /emmc/DCIM/* /sdcard/DCIM/
That will copy internal pictures and videos to sdcard

[Q] adb remount

Rooted with this method completely stock kernel...
Ok I am new to Samsung but not new to rooting and using adb. I have been searching and maybe I missed something but I can not get adb working properly on my phone and pc. adb remount does not work so I can not push any files over. I have tried all the methods with mount -o rw,remount -t yaffs2 ... etc...
I can get su permissions on the phone but it will not allow me to transfer any files over at all. I even tried to r/w permission with Root Explorer while connected to phone through cmd window and nada. I am not running CWM so I would like to push files over if I can. I have done it the root explorer way of copy and paste its just that way seems so sloppy to me.
Any help would be appreciated since I cant seem to find a method on the web that works for me
Thanks guys

How are you typing the push command? Remember there are 2 sdcards on this phone.
For the internal sdcard
Code:
adb push c:\this\place /sdcard
for the external sdcard
Code:
adb push c:\this\place /sdcard/external_sd
You *shouldn't* have to use mnt/sdcard/external_sd but give it a shot just to be sure.
Doesn't this phone have to be on for ADB to work? I thought I read that. Obviously that seems a bit odd since most have to be in recovery. Or am I wrong about the on part?
Lastly, if you can run 'adb shell' then use the 'cp' or 'mv' commands to get the files on there.
EDIT: Ok, I completely just misread your post. You're trying to write to the /system? Try mount -o remount,rw /system
I don't know why everyone uses the yaffs, mmcblk, and all the other craziness. You still mount /system just with more typing. Let me know if it works.

tried cp and mv still gave me problems moving file. I forget the error message I got. Also I know the proper push commands I used to do it with my Evo all the time. Its just that this phone wont let me mount system. What do you mean be on ADB?

I meant the phone needs to be on (with debugging selected) in order to use ADB and write to it. At least that's what I think I remember seeing. Could be wrong since I haven't used ADB with this phone yet.

correct all that has been done... all the basics you can think of have been done but it just keeps failing on adb remount
adb shell
$ su

no problem now, at first yes but I still cant mount system... driving me nuts since I dont use Clockwork right now I want to push files over... and my software on my pc AndroidCommander says NORoot has been obtained....

I'm probably as new to this phone as you are. Mostly just dealt with HTC. Past this point I have no idea what's going on. I can write to my /system - no problem. Hopefully one of the more seasoned guys will jump in here soon. Sorry I'm not much more of a help.

Did you save your photo's on your internal storage or on an external SD? If you saved them externally you can put your Micro SD in a flash drive and pull it up that way.

Or if for some reason you do not have access to an sdcard adapter you could use adb and pull them from the phone from a terminal.

Reboot into recovery(Not download mode). open a terminal and use adb's pull command. You could use adb's pull command in conjunction with the find command. Something like
Code:
adb shell find / -name "*.jpg" -exec adb pull {} ~/Documents +
This will pull all files ending with the jpg extensions. You can of course pull whole folders.
I just wrote that off the top of my head and it wasnt tested. I have to get to bed. I have to get up at 4:30am for work and it is now 11:30. Damn computer is so addicting! The one liner might not work but you get the point. Google adb pull and adb push.

A friend had the same issue a few weeks ago and I just popped her battery out and popped it back in. Then held the power + vol up + vol down till i felt vibration and held on for another 2 seconds. Then waited 20 seconds just to be safe. I connected my phone. I ran sudo adb devices in a terminal to make sure it was connected. Which is was and then ran the necessary commands.

That's a tough one... for me at least. I mean you are able to reboot into recovery but I am unaware of a method that will allow you to back your system up from a terminal. Adb has a backup command but you need to be able to see your screen to use it.
You could use the dd command over ssh ->
Code:
[B]sudo adb shell dd if=/dev/block/mmcblk0 | sudo ssh [email protected] "dd of=/~/Documents/recovery.img"[/B]
and check the progress with
Code:
[B]while true; do readarray -t array < <(pgrep -l '^dd$'); var=$(echo "${array[@]}" | sed 's/ dd//g'); kill -USR1 $var &>1 && sleep 5; done[/B]
but I "think" the FAT32 FS is limited to 4GB file transfers. So you will receive an error after 4GB's and the transfer will abort. Also, I am unsure of the t989's pit layout. Which blks you would need to backup if you did decide to dd single partitions. Like cache, system, recovery, boot, etc.
Maybe some computer whiz will be able to help you. I am sorry I couldn't help. Maybe one of the more experienced Linux/android users/devs can help you if you haven't already figured this out.
If someone did know, it would be cool if you could post the solution. I am curious as how to one would go about doing this.

Im hoping you are still around for some more assistance. Im actually in the middle of the same issue as OP, except possibly that the phone was completely stock with android debugging disabled, and the touch interface is also non-functional. You'd think that would be great for getting stuff off the phone, but I was unable to use the on screen menu to actually turn on usb mass storage.
I decided to try and use push / pull from recovery, however I found out that the directories I want arent available in recovery mode (DCIM / Download with a very very important 0000001.vcf in it).
I was able to get into recovery and use "adb reboot download" and Odin'd "recovery-cmw-hercules.tar" to the phone to give me a working CMR environment (v5.0.2.6). I thought I could feel my way through the menus after another "adb reboot recovery" to blindly guess - Vol Down x 6, Pwr x 1, Vol Up x 2, Pwr x1 - type thing, to navigate"mounts and storage" and then find "mount sdcard".
However, I have been unsuccessful. I did manage to mount system / data / cache , just not sdcard, and I dont know why.
TLR No screen, no touch. Odin'd CMR. Am sitting in Command Prompt with ADB Shell / Pull working. Still can't access ~/DCIM folder on internal SDCard. Hoping for some help. What am I missing? Bonus: A screen shot of the CWR mounts and storage menu would be very helpful!

Ok so i got it....
So I first used this comand:
Code:
adb shell find / -name "*jpeg"
It gave me this
/sdcard/Download/155546_394801767258170_1181721421_n.jpeg
Then i used this command to pull everything from my internal sd-card
Code:
adb pull sdcard C:/Docs
Worked like a Charm

[GUIDE] Authorize adb with broken digitizer.

So, yesterday my brothers Pit bull, Maggie, knocked my GS3 out of my hand and onto the cement driveway...
The result? A shattered screen, cracked display, and broken digitizer.
I wanted to perform a backup of my current rom (CM11 Latest Nightly) but figured out that my computer was not authorized for ADB.
Well, I wasn't about to let that stop me. Here is what I did to fix that little problem.
The following guide assumes that you already have the drivers for your phone installed and also that you have ADB set up.
I have only tested this on TWRP 2.7.1.0. I do not know if it will work on other recoveries.
First things first, power off your device by doing a battery pull.
This is the best way to ensure you are fully powered down since you can't see the screen.
Next, boot your device into recovery by pressing and holding the power, home, and volume up buttons.
Once you feel the device vibrate, release the buttons.
Plug in your phone and pull up a command prompt window.
Check and see if the device is being recognized by running
Code:
adb devices
.
Connect to the device by running
Code:
adb shell
.
Next, to mount the data partition where the files we need to edit are located, run the following code.
Code:
mount -t ext4 /dev/block/mmcblk0p15 /data
It is very important you type this exactly as written. Double check a few times to be sure.
Exit the shell by typing
Code:
exit
Now, we need to find our computer's adb key. For me, it was located in "C:\Users\%Username%\.Android\".
The file we are looking for is adbkey.pub.
Push this file to your device using
Code:
adb push adbkey.pub /sdcard/adbkey.pub
Pull up another shell by typing
Code:
adb shell
Remove the current adb key by typing
Code:
rm /data/misc/adb/adb_key
Insert the key into your phone's authorized keys by typing
Code:
cat /sdcard/adbkey.pub >> /data/misc/adb/adb_keys
Exit the shell
Reboot your device with
Code:
adb reboot
Profit! :good:

Hey buddy! Great tutorial! However, I'm getting an error trying to mount mmcblk0p15. I get the error:
"mount: mounting /dev/block/mmcblk0p15 on /data failed: Invalid argument"
Do i need super user privilege do to this?
Thanks! Great tutorial, btw.

Data Recovery via Download Mode

Afternoon all,
My G4 has hit the bootloop for the last few days. Periodically, it has powered up to the main screen, but not for long enough for me to recover data.
I just spoke to a data recovery place that told me that if I can put my phone into download mode, they can recover the data. Lo and behold, my phone is currently next to me in download mode!
I'm quite keen to avoid dropping that amount of money if possible, so does anyone know of a way to recover the internal memory of the phone via download mode?
Apologies if I'm duplicating a previous thread - I had a quick look, but couldn't see any with the same issue.

Probably when the phone is in download mode they can copy the partitions bit by bit then try to do data recovery from those partition images.
So if the phone doesn't boot, it doesn't mean the data partition is corrupted so in theory you could try to copy the data partition and mount it and see what files you can recover.
I do not know the exact commands to dump the data partition but I think that's the way it can be done.
Anyone else willing to give a hand here?

Thanks for the help so far. I believe the data is intact - when the phone starts up, the data is all there. It's just accessing it that is the issue.

something similar to
Code:
dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/mnt/media_rw/external_SD/data.img
OR
Code:
dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/dev/block/mmcblk1/data.img
don't quote me on that but in theory this should work...
make SURE you have a 32gb SDCard in the phone first

Where would that command be entered mate? Sorry, only ever used my phone stock before.

I thought the OP title said download mode?
Use the LG Root method as if you were going to root..
I'm mobile ATM but if I remember correctly...
Send_Command \\.\Com# [# meaning your com port number]
Then insert that command.
Tomorrow at work I can get a common list of partition names and the command to back it up with.

You need to mount the partition first.
Also, you could mount data if it is not encrypted (is it?)
Do this:
Code:
mkdir /temp
mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/

A little tip that should work :
Take the battery off your phone
Put both phone and battery in the fridge
Wait till the phone is cold and boot the device.
The bootloop trouble is due to an abnormal warm so this way you can have a one shot normal boot to backup your data before send for warranty.

If you try this, please put the phone in a ziploc bag 1st and seal it so humidity won't get inside the phone while in the fridge.

just a question though... How can you use this command if it will not boot?
---------- Post added at 08:59 AM ---------- Previous post was at 08:50 AM ----------
to get into download mode do the following...
Pull Battery
Hold Volume Up
Plug in USB Cable (make sure it's plugged in the computer)
Release button after 5 seconds
follow the link to grab the files needed for "Send_Command"
Grab LG Root here
once you are in the mode and you followed directions you can copy the command I wrote
above to copy your data partition. The reason you must have a 32gb+ SDCard is you will
be making an exact copy of the /data partition where you can remove the SDCard and recover
whatever is needed.

there is no need to mount the partition first..
the dd command will copy the partition as a RAW image.
you must then take it to a computer and mount it as an EXT4 or use it with ext2explore

in that case the command you have given him will copy 4492 mb only.
Here is why:
Code:
dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/dev/block/mmcblk1/data.img
input_file=(some partition) block_size=8192 skip_this_much_data=65536 how_many_data=548352 output_file=(somewhere)
actual data copied is 8192 * 548352 = 4492099584 bytes, and you are skipping some data from the beggining with 'skip'
you do still need to mount the sdcard, the "mmcblk1" is not treated as a directory, and it is very unlikely the sd card is mounted automatically in download mode.

remember me saying (if you read) above that I said "something similar to"

Hi all. Firstly, thanks for all your responses!
I've not got much of a clue what I'm doing unfortunately, I've never really messed with Android before - I'm typically fairly computer literate, but I've steered clear of messing with and rooting phones for the most part.
So to clarify, I've downloaded LG Root, Running either of the exes just leads to a cmd box that's open for about a second before closing, so I'm presuming I've missed a step. Is there a guide already in existence on how to use it?
But once in, ensure there's a sizeable Micro SD card in (it's a 64gb so I should be okay!) and use the send_command exe to send:
Code:
mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/
And then the entire image should be on the Micro SD card.
How would I then mount the data image to be readable? I've only used .iso for mounting before.
Apologies for my ignorance - I'm probably making helping me quite difficult!

Sorry all, correction to my previous:- Do I basically follow http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772
And replace step 10 with the above command?

Shift+Right Click the folder you extracted "open command prompt here" for starters...
Run ports.bat first...
It'll tell you your DIAG and communication port...
The second com port is the one you are looking for.

I'm having the same issue and actually tried this earlier today. Ports.bat didn't show a DIAG communication port even when I had the phone stably sitting in Download Mode.
Going to try the freezer trick. I already bought a Nexus 6P, just want to unlock the locked content on my SD card. lol.
EDIT: Holy crap! It worked. I chilled it in a baggie, then stood in front of the freezer as I unlocked all of my locked gallery files (1,411 files totaling 900MB). As soon as I was done, 30 seconds after stepping away from the freezer, it started to bootloop again.
Got the only information I needed off my phone...nice! I might give it another go tomorrow and see if I can't run ROM Toolbox and backup all my apps so it'll be easier to push to my N6P.
Awesome suggestion!

Hi all, sorry for the double posting, but just to make certain before I do something that will accidentally brick my phone. I'm intending to do the following:
Put phone in download mode and connect device.
Open LG_Root folder
Run a command window in LG_Root
Code:
Send_Command.exe \\.\Com4
Then, line by line, command:
Code:
mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/
Once I've done all this, what happens next? Will I see responses on the screen etc?
Again, I apologise for the probably stupid questions. I don't want to brick my phone and lose all of the data, but I'm going away with work so would like to square it before I go if I can.
Many thanks to you all so far.
