Hey guys,
I have a Nexus 7 2012 wifi only model. It has a cracked screen and need to retrieve data from it.
But the problem is that is has 4 users, 1 being administrative with pin lock. I can't remember the pin. And no usb debugging, nor rooted, no custom recovery, no unlocked bootloader, so can't remove the pattern via gesture.key method. Aroma file manager won't flash.
Also can't lose the data.
Please Help!

Hi, I do not know if your data is recoverable, but try the following (you need a computer):
1. Install ADB here if you don't have it: lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378
2. Plug your Nexus 7 into your computer's USB port.
3. Turn the Nexus 7 on while holding PWR + Volume Up, this should get you to the stock recovery mode
4. Open a CMD/Terminal window and type the following:
Code:
adb devices
5. The window should show your device in recovery mode
6. Next type the following into the window:
Code:
adb pull /sdcard /backup/<location-on-computer>
7. Replace '<location-on-computer>' with the location that you want to backup your files to (Make sure to keep the '/backup/' in front), ex. your desktop
8. The line will stay blank until it is done, once it is, all your files should be in a folder named 'backup' wherever you selected.
Hope this worked! If you absolutely need the data, you can always get the screen replaced.

Hey,
The device wont show up in adb while in stock recovery mode. Only sideload works. But still if i sideload, i lose all data.
Hi
I have a old nexus with broken touchscreen . I want to use it via mirror on pc.
unfortunatly USB debuggin wasn't enable so i can't install any app.
any tips?
thanks
PS: i saw many use usb adapter to connect a mouse but i don't have it
EDIT: right now i just need a rom/kernel with USB debugging mode enabled by default
the screen still works , only the touch screen is broken
power , and volume bottons still work
the device is rooted
If it's only installing apps you could install them via recovery. (as zip)
Or you could check for a cheap replacement touchscreen.

thanks for the answer!
sorry i forgot to mention that i need USB debuggin for make the app works correctly.
I'm trying now to find out what rom i have installed and maybe then find a kernel with OTG support . (yes i found a otg cable )
i'm not a expert of rooting
I think google has an app called voice control. Not sure how operational it is though. Supposedly you can control the entire system via voice.

i need to unlock the phone and tap on the widget "search" to start voice command .
I think the best way is to find a way to enable OTG and then use a usb mouse
Boot into Recovery and mount*Data*partition.
Open a shell on PC and type:
adb pull /data/property/persist.sys.usb.config ~/
Repace*~/*with home directory of your OS.
Open that file in a text editor and you would possibly see*mtp*written there. Change it to*mtp,adb.
Note that sometimes Android doesn't understand the text file changes if the line terminator is "DOS Terminators" which Notepad would probably do on Windows (mine is Linux so no issue here).
In that case, I would suggest not using*adb pullbut doing:
adb shell echo 'mtp,adb' > /data/property/persist.sys.usb.config
You may verify that the*echo*command overwrote the file by using:
adb pull /data/property/persist.sys.usb.config ~/
and seeing the file's content in some text editor.
Unmount*Data*and reboot into Android OS. USB Debugging would probably be enabled.

i tryed
1) i went in recovery mode
2) i connect via usb the nexus4 to my pc
3)went in "mounts and storage"
4)then "mount /data"
5)in cmd i tryed your command "adb pull /data/property/persist.sys.usb.config" but i says i'm unauthorized
i checked via command "adb devices" and it return a alphanumerica string plus "unauthorized"
i tryed then to
Reboot your phone into recovery mode.
Connect it to your computer.
Open the terminal and type:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
adb shell reboot
but it still says error : device unauthorizated . please check the confirmation dialog on your device
i tryed also with a different version of adb and now gives me after "adb devices" an "offline" response
NB: if i connect the phone (not in recovery mode) via usb i can copy files in and out (i can explore onlyfew folders) , maybe this could help.

Sorry but this could not help... Now only thing you can do is connect any USB mouse to your phone via otg cable (as it is not costly also), and you can also try USB gamepad. I also have used USB gamepad before when my touchscreen was not working.
Second thing you can do is download any android device manager for your PC like mobogenie or mobilego they directly install any app from play store to you android device, through USB.And I don't think they need USB debugging option to be enabled.

my problem is not installing an app (i could do it in recovery mode with a .zip) but enabling the USB debuggin
I have a otg cable but not the "Y" type ( the one with power source ) , also i don't know if OTG is supported by my kernel . I would like to install maybe another kernel which has OTG support and usb debuggin mode enable by default but i don't know what kind of rom i have D:

Recently, I successfully ported TWRP from Coolpad Note 3 Lite to Modena 2. After testing, everything works fine, on both devices. Since this device has locked bootloader, we need to bypass this by enabling fastmmi mode and factory mode to enable temporary root access and make initial backup and flashing. So, let´s get started.
Remember to read this post carefully. I am not resposible for any damage to your device. If you brick your device while flashing the TWRP you can *almost* always recover it using SP Flash Tool and YGDP Tool
IF YOU ACCIDENTALY BRICK YOUR DEVICE AND YOU WANT TO FLASH IT VIA SPFT, DO NOT FORMAT THE DEVICE IN SPFT!!! If you´ll format partitions in TWRP, that´s fine, but don´t do FORMAT ALL + DOWNLOAD or FIRMWARE UPGRADE! This will brick your device, like mine This tutorial will not (hopefully) brick it, but just in case something goes wrong, now you know what not to do.
Preparing the environment on your computer
Windows
Download ADB and Fastboot from this link
Open it
Install it system-wide
Also, install the drivers
GNU/Linux (Ubuntu / Debian based distros)
Open terminal
Type "sudo apt install adb fastboot libusb-dev" without the quotes (")
Other things, that are required
Since the file size of the recovery exceeds the maximum 8MB of allowed upload size, you can download it from DataFileHost.
Preparing the device
First, you need to remeber that this could render your device unbootable and will void warranty.
Enable developer options
Go to Settings -> About phone
Tap the build number 7 times
Go back
Go to Developer options
Make sure OEM unlocking and USB Debugging is enabled
Enabling factory mode
Open dialer app
Dial *#9527*#
Click on "DM"
You will be prompted to insert RD personnel password. Enter: 54321
Click cancel button
DM button should change colour to RED
Exit the app by clicking home button
Installing and setting up openrp app
Open terminal / command prompt
Type:
Code:
adb start-server
Type:
Code:
adb devices
Now, click on your phone allow debugging and make sure to tick the radiobutton to remember / always trust this computer
Type:
Code:
adb install
Press spacebar after the install word and drag and drop the downloaded openrp.apk file to terminal
Hit enter
After it´s done, type:
Code:
adb shell monkey -p com.yulong.openrp -v 500
Now, the fun part. ROOTING the device
But before that, BACKUP
Now, keep your phone plugged in, and do a normal reboot by pressing and holding the power button and clicking reboot
When it vibrates, press and hold the Volume down key (Vol-)
You will see these lines on the screen:
Code:
=>[Factory mode]
Code:
=>VolumeDown key is pressed
Code:
=>[fastmmi mode]
After that, you´ll see the LED turns green and "Up Down" text on the screen
Now, back to your computer, type in the command prompt
Code:
adb devices
You should see XXXXXXXXXXXXXX device listed (where XXXX... is the serial number)
Type in the command prompt:
Code:
adb shell dd if=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/recovery of=/storage/self/primary/stock_recovery.img
and
Code:
adb shell dd if=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/boot of=/storage/self/primary/stock_bootimg.img
Flashing the TWRP Image
Type in the command prompt:
Code:
adb push (drag and drop the recovery image file here, like you did with the openrp.apk file) /storage/self/primary/
Type:
Code:
adb reboot
Press and hold VolumeDown key (Vol-) to boot to fastmmi mode
Type:
Code:
adb shell dd if=/storage/self/primary/recovery_twrp_e502.img of=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/recovery
Type
Code:
adb reboot
Press and hold the VolumeUp key (Vol+) to boot into recovery. If you see white screen with "Recovery" text in it, congrats. Everything is working. If not, try again.
Flashing the SuperSU package
Download the zip from SuperSU website
Copy the zip over to the device, with TWRP running
In TWRP, click install, click the zip and confirm the installation.
Factory reset is not required, but you should at least wipe the cache

Hi i have a problem here. at the part to drag and drop the openrp file. When i have downloaded the file a drag it and drop it after the install word. The problem is that if I want to drop it there it will do nothing, nothing there shows or anything. Please respond.
I guess you can type the path to the installation file instead of dragging.
Hello,
Very helpful thread, my coolpad Modena 2 (E502) is now rooted.
Don't forget to disable the factory mode once everything is done, or you won't be able to access the storage to usb anymore.
Thanks.
helo, can i get help, when i try to install openrp on abd and fastboot, it printed this message "Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE]"
can anyone help me on that step, so i can root my e502

Hello,
If I recall correctly (I don't have the phone anymore, just touched it once to root it at the time), you basically undo the "Enabling factory mode" step.
I think if you dial the number, you'll be back in the menu where you have the option to disable the factory mode.
Factory mode should be disabled when 'DM' is green.
Good luck
very good
Need Custom rom please

Hello, could you resend the twrp recovery file for this phone again?. old links not work!.
(sorry for my bad english)
Hi,
I think I've already explain everything in title.
My Galaxy S5 on Android 8 (I think) as her screen broken (black)
Before that it already wokr badly and slowly. I bought a new phone but this one break just before I can transfer data.
I can unlock the patern (I know that because the volume + buton react)
Smart switch say that the phone is locked (even it's not true). Tested on 2 PC
The phone appear in Windows but no file or folder appear.
In adb the device is shown unauthorised and even if I click where the message to unlock should be, notihng append.
The phone is connected on Wifi, apparear in Google Find it but not Samsung find it...
I think that it's already to much information...
My question : how can I do the unlock the phone and do a smart switch backup ? or an other way to transfer data.
Regards
James
The Samsung Galaxy S10 comes with a USB OTG adapter. OTG stands for "On the Go" and is used for the connection between smartphone and USB stick / cable. Connect this USB OTG adapter to the USB Type C port of your Samsung, then connect the USB OTG adapter with USB Type C port of your computer.
You should see the data stored on your Samsung.

It's an S5. But I have a OTG adaptor for it but my new phone A52s doesn't connect to the S5.
I try with a S7 but I can see that there is a lot autorisation to give on the old phone which will be very hard to do with a black screen.
If ADB is unauthorized, the only way to back up any data would be via a custom recovery. That would require that the device have an unlocked bootloader though

ADB authorised is not require for Smart Switch... I think
And my device have access to recovery and it's root so the bootloader is unlocked.

So then flash a custom recovery, and then enter it. That will either give you MTP access to the files and folders, or ADB should also be enabled - and does not require authorization

purehaps you have forget that the screen is broken. I can't access the phone for complicated manipulation. I'have already have TWRP installed on it but without a view it's impossible to manipulate it. Also, it's not normal that the phone are not viewed on windows or is shown locked on smart switch.
In recovery mode, the phone isn't show on windows also. Find the MTP option in TWRP without a screen view is very diffucult and dangerous, (the wipe option are near)
If I can access file on phone I will be able to view screenshot and configure it.

1. No, I didn't forget that the screen is broken
2. I wasn't telling you to press anything in TWRP. When it's in TWRP and you plug it in, you will either get MTP and/or ADB access automatically
3. Yes, it is perfectly normal to not have access to the files and folders in Windows, when it's powered on normally. There's a popup on the phone that you have to tap in order to grant permission to the folders and files. That's why it shows up as an empty device when you plug it in while in normal mode

Ok excuse me.
Hum when I'm in recovery mode, my phone doesn't appear in Widows. And in adb, I haven't access to all folder. Data is empty for exemple.
For 3. Ok, I don't remember this notification. But I'm shure that I'have already use this phone with my PC. If I wasn't able to ring it on Whastapp, I will think that the phone doesn't works anymore at all. But it's not the case.

ADB commands work by default while in TWRP, you can back up almost anything that your TWRP version allows through your PC using ADB commands, TWRP will serve as intermediary, but you will not go to operate over your broken screen device but through your ADB/fastboot CMD.
In normal mode I can unlock the phone but after that even if I click where the message should appear it doesn't do anything.
In adb I can't access a backup command (and if I can do this, It will not the easyer way to transfer my sms.)
I have some old other phones to see some message exemple and know where to clic but it doesn't works. I have install Vyzor, It asks me a permission but even if I tap in the right of the screen the permission doesn't works.
I also try to transfert a new adb key but I think it doesn't work because Wyzor still ask permission.

There is no backup command in ADB that you can use. And the reason that you can't access /data is because that requires going into TWRP settings and mounting the system partition.
What you can do in TWRP is to adb pull all of the files and folders off of the internal storage
Other thing, I can phone my phone with Whatsapp but I can't click to hang off.

ADB backup is not to operate while your device is on, but it is to operate while your device is in TWRP mode.
TWRP has integrated by default the ADB options not need to authorize through your broken screen because it is already authorized.
Messages as an app user (the same with root or system user) is part of userdata, you want to back up userdata to restore it after in other device or a scenery where your device get repaired, no?
I'll give you an example, you have to use this command, create a folder on a convenient place onto your PC directory, something like "BACKUP", assuming that you set it up correctly the environment for ADB/fastboot to use it along all of your system, you should open from this newly created folder an CMD (I use the new Windows terminal for easy/comfortable results) then type from the terminal adb shell twrp backup userdata , you'll have the userdata backed up in your PC in less of 2 minutes depending on the size of the partition, and so on successively.
What you can back up from TWRP depends on the restrictions from your TWRP version, you should back up the normal that you can see from the TWRP screen and even more but for example if your TWRP have some issues mounting vendor partition of course the ADB commands can't do the job for this specific partition, but anyway you have a lot you can do through it.

1. The command depends on what the mount point for your internal storage is. The command would be "adb pull /(mount point)" , so it could be:
adb pull /sdcard
adb pull /storage0/sdcard
Or several others
2. No, you can't connect with Smart Switch without allowing permission on the popup box on the phone screen

I'm not sure I understand your command. But it return a result. "Backup" is the name of a folder ? or it's a commande for twrp ?
Is there a way to be sure that twrp is installed (with all my phone, sometime, I don't remember what is on it. The thing it's sure it that this phone is root because I use root function with some app but perhaps just with magisk or Super SU.
