Hello everyone,
my phone (Xiaomi MI 9T) has fallen in the water and now it's partially working.
I really need to recover some data from it, but any method I've found on the internet requires USB Debug active. The phone turns on but it works only as long as it stays on the lock screen or if I go to settings from the notification bar. If I unlock it, the launcher doesn't work (but I can still drag down the notification's bar) and after few seconds the phone reboots I'm also able to activate the toggle of the USB Debug but it looks like it doesn't stay active because if I go back and re-enter developer's section, USB Debug is OFF.
At this point I don't really know what to do. The phone enters fastboot and recovery mode, unfortunately everything is stock, so my possibilities are limited.
I haven't tried to change the screen, but I doubt that would solve the problem, since if I stay in those specific areas, it works fine.

Due to the security implications of remotely enabling USB Debugging, the only way to enable it is through Developer Options. You can try rebooting to recovery and clearing cache although I am doubtful as to how much that might help you. If your device took a swim, you're going to be looking at repair, which will most likely result in wiping your data.

Do you know if changing the screen could solve the problem? Or do you think there's a way to copy data 1:1 on another device (such as a used mi 9t I could buy)?

How long ago was it dropped in water, have you allowed it thoroughly dry out? Can you open the body of the device to allow it to dry?

It stayed in the water for few seconds, the bottom half of it. I shut it down and I let it dry for 2 days, after removing the battery. Anyway I brought it to a center that made a treatment for electronic contacts, an they said that it's needed to change the display first, then run some tests to see what else is wrong. The problem is that changing the screen costs 130€ and, in my opinion, won't solve the issue.

Can you find a stock update for your specific model number in the form ol stock update.zip that can be flashed in your stock recovery like a OTA update? If so, you might be able to extract the build.prop file from the update then open the build.prop file in a note editor and edit the file by adding or editing lines that enable USB debugging. Then save the file. Then remove everything from the update.zip except for the Meta-inf or "updater script" file/folder then place your modified build.prop file in the update.zip so that it is the only thing in the zip other than the Meta-inf/updater script. Then put it on external sdcard, insert it into your device and boot into stock recovery then choose the option that lets you install updates from sdcard and try flashing your modified update.zip file and reboot the device, if it works, it will enable USB debugging. The next obstacle is getting past your lock screen, which is pointless if the device reboots in seconds. If you can get it to stop rebooting, you might be able to use adb to unlock the lock screen by using adb commands that simulate the touch input required to unlock the screen. You'll have to do some searching to find out the "address" and order of each part of the screen that you need to simulate the touch input on the screen in the right order. It's a bit complicated for those that aren't familiar but it can be done if you do the research.
Or,you can try connecting a USB mouse to the device and see if it will let you open the lock screen.

Plus, I don't really get why the system fails right after the lockscreen, I'm actually able to enter the code and the phone unlocks but the launcher seems not working, while the notifications bar works fine, and after some seconds the phone reboots. How can the system work fine in some aspects and bad in others at the same time? Can it be some flash memory issue?

That or kernel panic due to some other important hardware is damaged.
Maybe you can use a adb script to interrupt the running processes right after the device unlocks. Something to stop everything from loading beyond screen unlock. It might allow you to use adb to pull whatever you want from the device via adb pull commands.
Or, if there is a custom recovery for your device and if your bootloader is already unlocked(if it isn', don't unlock it, it will wipe your data), you can install the custom recovery and use it to create a backup of your data then extract your data from the backup.

Unfortunately I still have the stock recovery. Plus USB debug is deactivated. What really boggles me is the fact that I can still enter settings and get to developer options, turn ON the toggle of USB debug, but it's like the phone doesn't save the setting, cause if I go back to the main setting screen and enter again developer options, USB debug is OFF. I mean, what the hell?
Having access to device's Stock Recovery you can try as shown below to enable ADB / USB Debug ging: yes you can run Android shell commands from within Android's Stock Recovery.
Unplug device's USB-connection , boot into recovery mode. Having successfully booted into recovery mode, connect device via USB-cable with computer - what switches the USB driver to ADB mode.
Now enable USB debugging via recovery:
Code:
adb shell
echo "persist.service.adb.enable=1" >> /system/build.prop
echo "persist.service.debuggable=1" >> /system/build.prop
echo "persist.sys.usb.config=adb,mtp" >> /system/build.prop"
reboot

My daughter's Nexus S touchscreen has died. It died slowly in that on the first few occasions she couild pop the battery and it would come back. Now it won't come back at all and is stuck on the pattern lock screen.
Before we send the phone for repair under warranty she is keen to get the photos off the phone since a repair might reset the phone. I was thinking we could mount the phone as a USB device but it doesn't show up perhaps because it won't until the pattern lock is entered else anybody could get data off your phone bypassing security.
Any other things we could try before giving up and hoping the repair doesn't delete all the data?
Thanks

Out of interest I tried this on my GN. adb recognises the phone and adb devices shows the serial number. But adb pull /sdcard says invalid remote file. No idea what that means since using ES File Explorer sdcard is a valid directory on the phone (and I suppose it would also be on the Nexus S)

ADB "thought" you meant to copy a file.
To copy the entire sdcard directory you should do something like this:
Code:
adb pull /sdcard/ sdcard/backup/on/pc/
The command parameters are "adb pull <source> <destination>"
Just make sure source ends with a /
Maybe a Windows based software?? Droid Explorer, very useful.. http://de.codeplex.com/ :good:
Well I finally got the phone to play with. The screen indeed dead. I installed the Google USB drivers from the SDK and also the Samsung drivers.
When I boot the phone into the recovery menu I can run fastboot devices and see the following
????0AC4B09900?? fastboot (of course the ? are not there but I wanted to anonmyuse the serial)
So far so good.
In device manager under Android Phone it show Samsung Android ADB Interface
But if I try adb devices I get nothing.
Forgot to mention my daughter said USB Debugging was turned off but I am not sure that makes any difference and anyway, we can't boot Android to turn it on
So I select Recovery and see the Android with the exclamation mark. Windows beeps to indicate that some sort of devices has been installed,
But in Device Manager no phone shows which explains why adb can't fidn the phone but not why.
I can bring up the recovery menu but still no adb
Any suggestions?
Thanks

If you unlock the bootloader to flash CWM your memory will also be wiped, so you will loose all the photos you want to save, so don't do that.
Also if you have the USB debugging off, the ADB commands won't work. I'm afraid you're SOL, since you have the bootloader locked you can't flash a kernel with USB host, that would allow you to use a mouse to navigate in the phone and since you don't have USB debug you can't pull files from the "SDcard"... Better take it to the store and try to ask them if they can save the photos before they do anything to the phone, but i guess if it's a digitalizer problem, they won't mess with the NAND.
Check out http://www.moborobo.com/ and see if it works for you.
If you have root you have extended functionality, like control the device from the PC. But if i recall correctly, even without root you should be able to get your files.
I installed the OTA update last night and it's just looping through the "alcatel one touch" and "smart move" screens. It's been like that for hours.
I need assistance in getting into recovery mode, and hopefully getting my files off the device.
I have downloaded android-studio and am about to install it to get adb and fastboot, and have downloaded the drivers for the idol 3. At this point when it's plugged in, my computer doesn't recognize the device.
If you did not have usb debugging enabled BEFORE the boot loop installing adb and fastboot now won't do you any good. Are you still able to get into recovery and is it twrp or the factory recovery? Without a direct way to get the phone into bootloader regretfully the only solution is to send it in for warranty repair (or replacement via your credit card if you paid that way under purchase protection)
Are you trying to remove the data to prevent access by others or because you need the data? Did you make any backups to external sd or copied to the pc?
I as well am stuck in bootloop. Was able to get into factory recovery and reset phone several times. Still no luck. I have a TWRP backup, but how to I do a temporary boot into it? Only option available in factory recovery was to sideload via ADB, but no luck using fastboot commands there. Phoned Alcatel and they have referred me back to Amazon. Amazon only wants to refund me, won't exchange! Of course I bought at the pre-order price. Any help would be greatly appreciated.

The factory reset killed you....if you had usb debugging enabled prior and had not done a factory reset (which kills /data) you could have possibly gotten to an adb shell long enough to do an adb reboot bootloader. The problem is there's no way now to get you into bootloader....you can't get to it from recovery (factory).
If you purchased it by credit card you might see if their purchase protection (typically 60-90 days) allows a claim submission for a replacement....in this case they would cut you a check for the cost of a replacement after mailing in your old one. That's the only solution I see to remain at the $199 price.
You could also see if amazon will issue a $50 credit to your account in addition to return to allow for repurchase. Unlikely but possible.
Ok thanks for the input and advice. As a last ditch effort, is there a way to create or modify the twrp file as a "signed" zip file so that I could boot into it via stock recovery. This was how I rooted my old Galaxy S2, although it was a CWM recovery.

Nothing so far has worked in that regard...in fact I created a update.zip using "zipme" to replace the build.prop that another user says the factory recovery refused to process.
Without a full factory rom to pull needed info in or the source code to compile one we can't do some of the things which would "save" the device.

There is no option for screenshot while the phone is in the stock recovery. I need a camera to take a picture of the menu. I can do this later. The menu however looks like this:
Code:
reboot system now
apply update from ADB
apply update from sdcard
apply update from phone storage
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down
view recovery log

If it's right off the main page like that then I can confirm it's not on the 6045. It's been one of the main issues with folks bricking their devices...if their rom gets messed up and they have factory recovery they have no way to get into bootloader to do anything to repair the device. Seems alcatel needs to add the reboot to bootloader to our recovery. I wonder where we could report that.
Is there a way to "lock" recovery so the updates cannot replace twrp? TWRP allows adb access and reboot to bootloader.

This is a snapshot from the recovery menu of 6039y.
The short answer of your question regarding the "lock" is ... no. If a longer explanation is needed ... this is from the update file, a link to which was provided by you:
Code:
if ! applypatch -c EMMC:/dev/block/bootdevice/by-name/recovery:18393344:f9062580503eb61b315a5d12c5c6b3bb133aa4b2; then
....etc.
what it does is to check the sha1 sum of the recovery partition and if the sha1 sum doesn't match to f9062580503eb61b315a5d12c5c6b3bb133aa4b2 will continue with an overwriting of the recovery partition and then will apply a patch. It can't be changed because the whole update will fail.
yep no bootloader

Back to the "lock" question. Probably it is possible the OTA update to be slightly modified and then to be flashed through the TWRP recovery (there is an option in TWRP to skip the signature verification ... the verification will fail if the zip file is modified). But I prefer to wait for the OTA update of the 6039y, as I want to perform some tests with the upgrade.

I am in the same boat as OP re the state my Idol 3 (6045i) is currently in. I also unchecked superuser but did not unroot completely before installing the update. I have not yet done a data wipe through recovery though. Unfortunately, back when I rooted the phone I did NOT check the box telling the phone to remember the computer/RSA key for future use. As a result, now when the phone is stuck at the white/animated Alcatel boot logo I can see the phone under adb devices, but it shows as unauthorized.
One thing that did seem odd, was browsing through stock recovery when trying to browse to apply an update from either phone storage or the SD card, no files are showing up at all. All it is showing is the folder root ( /.. ) in both instances and nothing else. Even after I attempted loading several system update and twrp images (in .zip and .img formats) on the SD card from my computer, once loaded in the phone none of the files show up through stock recovery. Is this SD card not compatible/formatted wrong or is something else going on?
Is there any current method to gaining access to the phone via adb manupulating the adbkey files in the $User$/Home/.android folder? I do currently have the adbkey files on my Mac from connecting the phone previously. I'm assuming these files are uniquely generated hashes?
That is ridiculous if the 6045k has bootloader access from recovery and 6045i does not. What would be the reasoning for this?

Does the sha1 sum of your recovery happen to match f9062580503eb61b315a5d12c5c6b3bb133aa4b2 ? If so it could solve some issues but why do I suddenly think all 3 models have their own recovery?

adb reboot bootloader won't work even with it showing unauthorized? If you can get into bootloader you can fix /system without messing up your /data (don't wipe data or you lose adb entirely...you may figure out how to add the correct hash if we can find how it's generated)
Here's some info on the hashes you might find useful taken from: http://nelenkov.blogspot.com/2013/02/secure-usb-debugging-in-android-422.html
Secure ADB implementation
The ADB host authentication functionality is enabled by default when the ro.adb.secure system property is set to 1, and there is no way to disable it via the system settings interface (which is a good thing). The device is initially in the OFFLINE state and only goes into the ONLINE state once the host has authenticated. As you may already know, hosts use RSA keys in order to authenticate to the ADB daemon on the device. Authentication is typically a three step process:
After a host tries to connect, the device sends and AUTH message of type TOKEN that includes a 20 byte random value (read from /dev/urandom).
The host responds with a SIGNATURE packet that includes a SHA1withRSA signature of the random token with one of its private keys.
The device tries to verify the received signature, and if signature verification succeeds, it responds with a CONNECT message and goes into the ONLINE state. If verification fails, either because the signature value doesn't match or because there is no corresponding public key to verify with, the device sends another AUTH TOKEN with a new random value, so that the host can try authenticating again (slowing down if the number of failures goes over a certain threshold).
Signature verification typically fails the first time you connect the device to a new host because it doesn't yet have the host key. In that case the host sends its public key in an AUTH RSAPUBLICKEY message. The device takes the MD5 hash of that key and displays it in the 'Allow USB debugging' confirmation dialog. Since adbd is a native daemon, the key needs to be passed to the main Android OS. This is accomplished by simply writing the key to a local socket (aptly named, 'adbd'). When you enable ADB debugging from the developer settings screen, a thread that listens to the 'adbd' socket is started. When it receives a message starting with "PK" it treats it as a public key, parses it, calculates the MD5 hash and displays the confirmation dialog (an activity actually, part of the SystemUI package). If you tap 'OK', it sends a simple simple "OK" response and adbd uses the key to verify the authentication message (otherwise it just stays offline). In case you check the 'Always allow from this computer' checkbox, the public key is written to disk and automatically used for signature verification the next time you connect to the same host. The allow/deny debugging functionality, along with starting/stopping the adbd daemon, is exposed as public methods of the UsbDeviceManager system service.
We've described the ADB authentication protocol in some detail, but haven't said much about the actual keys used in the process. Those are 2048-bit RSA keys and are generated by the local ADB server. They are typically stored in $HOME/.android as adbkey and adbkey.pub. On Windows that usually translates to %USERPOFILE%\.android, but keys might end up in C:\Windows\System32\config\systemprofile\.android in some cases (see issue 49465). The default key directory can be overridden by setting the ANDROID_SDK_HOME environment variable. If the ADB_VENDOR_KEYS environment variable is set, the directory it points to is also searched for keys. If no keys are found in any of the above locations, a new key pair is generated and saved. On the device, keys are stored in the /data/misc/adb/adb_keys file, and new authorized keys are appended to the same file as you accept them. Read-only 'vendor keys' are stored in the /adb_keys file, but it doesn't seem to exist on current Nexus devices. The private key is in standard OpenSSL PEM format, while the public one consists of the Base 64 encoded key followed by a `[email protected]` user identifier, separated by space. The user identifier doesn't seem to be used at the moment and is only meaningful on Unix-based OS'es, on Windows it is always '[email protected]'.
While the USB debugging confirmation dialog helpfully displays a key fingerprint to let you verify you are connected to the expected host, the adb client doesn't have a handy command to print the fingerprint of the host key. You might think that there is little room for confusion: after all there is only one cable plugged to a single machine, but if you are running a couple of VMs, thing can get a little fuzzy. Here's one of way of displaying the host key's fingerprint in the same format the confirmation dialog uses (run in $HOME/.android or specify the full path to the public key file):
awk '{print $1}' < adbkey.pub|openssl base64 -A -d -a \
|openssl md5 -c|awk '{print $2}'|tr '[:lower:]' '[:upper:]'
We've reviewed how secure ADB debugging is implemented and have shown why it is needed, but just to show that all of this solves a real problem, we'll finish off with a screenshot of what a failed ADB attack against an 4.2.2 device from another Android device looks like:

Just tested using adb reboot bootloader again and this is the result: error: device unauthorized. Please check the confirmation dialog on your device.
Something else I tried was running fastboot commands in the narrow window that the phone initially boots (black screen with Android logo) but that didn't seem to work either. I tried:
fastboot reboot-bootloader
fastboot -i 0x1bbb reboot-bootloader
fastboot -i 0x1bbb devices
I noticed if you plug the phone into the computer via USB while the phone is off, it will briefly power on to the Android logo/black screen before flashing the battery status once and turning off. Is this an opportunity to send fastboot or adb commands to the phone?
I'll try messing with the adbkey stuff later when I have time to dig into it.
There is a tool from Alcatel (TCL) which can perform upgrades of the device from a Windows PC. You can try it if nothing else helps. There are two COM ports available under Windows when the device is powered off and the USB cable is connected to the phone. This tool use them to perform some checks on the device and probably will continue with an upgrade (it says that all of your data will be wiped after the upgrade etc. so there is a possibility to overwrite everything with a stock image) ... there are instructions how to work with it. The link is from the French support section of Alcatel. Despite that the program has support for 6039 and 6045 is not clear for which of their versions.

The problem is we currently have no stock images in the format it requires to flash to restore the device. I would think those have to be available first?

You can't do fastboot commands until the phone is IN bootloader....so you'd have to do adb reboot bootloader
adb devices
etc....

It is possible the program to download these images from a server.
I found another interesting thing. The device has a download mode. It is activated when the phone is powered off and connected to a PC. You must wait the display to turn off after the charging battery symbol and then to press and hold both volume keys, after which to press and hold the power button (without releasing these for the volume). But still don't know what to do in this mode. No device is detected on my Linux box when the phone is in this state. Probably I should try in Windows.
Also when the Alcatel upgrade tool was trying to detect the phone I'm almost sure that one of the COM ports was
Qualcomm HS-USB Diagnostics 9006
there is a lot information for other devices how this can be used to unbrick your phone, so this is a some start. The images which the people flash through it are in raw format.
Hi,
I tried lots of things! Can't do anything yet... I really need that file.
My USB debugging is not turned on, if it was I'll be ok. I found that if you copy the adbkey.pub from your users directory to the phone it
will bypass the USB debugging function, but can't push it with adb.
I can only boot in recovery and use fastboot or adb but with no access to the phone... I don't have TWRP installed.
I tried to flash TWRP with: fastboot flash recovery twrp.img
and I got an error telling me: FAILED (remote: 'No such partition.')
Probably because USB debug is not enabled... again...?
EDIT: tried to make me a walkthrough for the keyboard using a working phone, I can get up to the settings app, there's no focus on the settings items so I can't select them...
- I have access to the fingerprint sensor, but not gonna do much since I rebooted the phone i'll need to enter the unlock code.
- I can plug in a keyboard/mouse combo in my phone, for this to work i'll need a walkthough for arrows key/enter key to press to I can enable USB debugging.
- The screen is broken(black) touch sensor also broken.
- The phone is not rooted but is OEM unlocked
- I tried several software to mirror screen, they all require USB debugging enable or accept something on the phone or both.
- I know where the file is located on the phone but I don't know it's exact name (it's a .mp3 file, not a song ) it's in /storage/emulated/0/Recorders
Any help is greatly appreciated.
Thank you
Hi,
My girlfriend's Mi A3 is stuck in bootloop. I know this problem has been often addressed here but first thing: she did not flash ROM or rooted, I'm not even sure what it entirely means and implies. Anyway she found her phone stuck on the screen with 2 choices: try again or factory data reset. See attached files.
The problem here is that she would like to have access to the pictures and do a back up. Sure, she should have done it before but she didn't so here we are...
I've tried the combinations, power button volume down, volume +... Etc. It lead me to the different screens in the attached files...
I want to know, is there any way she can access her pictures, files etc.?
For information, she probably didn't enable the developer options debogging usb or something like that, she has no SD card. I guess we could reset the phone but is there anyway to recover files after that?
Can you guys help us?
Edit: sorry I thought I posted it in the mi A3 thread I don't know if it's best here or there...?
As long as phone is accessible by means of ADB - what's the door to phone's Android , it should be possible to pull out the data you're interested in, otherwise you've no chance.
Oh ok so that's my only chance here?! And how do I process? Doesn't ADB have something to do with the developper option and usb debogging?
I guess if it wasn't already enabled we're screwed?
I fixed it! Someone on reddit gave me some instructions and it worked. For others that might have the same problem...
Download https://dl.google.com/android/repository/platform-tools_r30.0.5-windows.zip and extract them anywhere
Download the ota file https://bigota.d.miui.com/V12.0.3.0...AGlobal_V12.0.3.0.RFQEUXM_a3af6e0308_11.0.ziphttps://bigota.d.miui.com/V12.0.3.0...AGlobal_V12.0.3.0.RFQEUXM_a3af6e0308_11.0.zip and put it in the same folder where adb.exe is. Rename it to "ota.zip".
Launch cmd in the folder where adb.exe is and enter the command "adb start-server"
Choose "apply update from adb" on recovery mode on your device and connect it to your pc
Enter the command "adb devices" to check if adb recognizes your phone and then enter "adb sideload ota.zip"
wait till it finishes
So I had a pixel 6 pro and unfortunately my wife got mad and threw it against the wall a few times, causing the frame to bend and entire back glass to shatter. The front LCD didn't break, but glue came apart and it separated from the frame.
I had all my 2fa accounts on there, as well as very valuable data that I need to recover.
The phone still powers on, but there's nothing visible on the screen. A local repair shop advised we start by replacing the screen and then work on transferring everything out.
I have a replacement pixel 4a and want to be prepared for when my phone comes back online.
What's the best way to backup my 6 pro and restore on the 4a?
I need everything copied as a whole image, and restored on the 4a. I want to be able to boot up my 4a, open my authenticator app, and have all my accounts listed there.
Someone please tell me this is possible, and if so, please post instructions.
Thank you in advance.
I doubt 1:1 image cloning is possible because encryption is hardware-backed and therefore device-unique. it's not even possible to restore backup on origin device after factory reset since android apps can use keystore in TEE.
side note: you could connect HDMI multiport usb-c otg adapter to TV and mouse so you have access to phone at least

The HDMI multiport didn't work. Nothing was displayed. I don't know if it's because my phone is badly damaged, or if the pixel 6 doesn't support HDMI out over USB C
I tried this one https://www.amazon.com/dp/B081VBSNRZ/ref=cm_sw_r_apan_i_5NF5RPBKZ97YW4KFW9AX
What are my other options?
the best option would be previously unlocked bootloader, so you can have full access. but you did not unlock bootloader so this is no option for you, because unlocking will factory reset device.
HDMI might require some setting or app installed on device. apps can installed remotely from PC google play with proper google play account. not sure how to start an app though, but guess app can autostart.
at least usb keyboard is working, you could try to navigate blind and enable usb-debugging, this would allow you to use scrcpy. maybe connect headphones or use talkback to get some kind of audio feedback.
of course both methods requires some information from another identical device and need to tested on fully functional pixel 6 pro before..

This is not a full backup, but it might help you interactively recover some items without replacing the broken screen. Also, assuming this is something you're still looking to solve...
If you have adb debugging enabled, you can try to use https://github.com/Genymobile/scrcpy to interact with your phone over USB from a computer.
If you do not have adb debugging enabled, you can try to enable it via Recovery Mode. The steps to enable Recovery Mode below are from https://www.tenorshare.com/android/how-to-enable-usb-debugging-on-android-with-black-screen.html (I have not tried these steps).
Less:
To enable ADB without a screen:
1. Download the ADB toolkit for your computer and extract its contents to a folder.
ADB toolkit can be found at https://developer.android.com/studio/releases/platform-tools
ADB requires you have USB debugging enabled on your phone.
Since your phone has a black screen, reboot your phone into recovery mode to accomplish this.
Press the Volume Down and Power buttons at the same time to enter recovery mode.
2. Connect your phone to your computer, open a Command Prompt window in the ADB folder, and type the following command.
adb devices
3. You should see your device listed there.
Run the following commands one by one.
adb shell
mount data
mount system
4. Use the following command to pull the persist.sys.usb.config file from your phone to the PC.
adb pull /data/property/persist.sys.usb.config C:\Users\[your-username]\Desktop\
5. Access the persist.sys.usb.config file on your computer with a text editor and edit it to mtp,adb.
6. Run the following command to send the file back to your device.
adb push "C:\Users\[your-username]\Desktop/persist.sys.usb.config" /data/property
7. Download the build.prop file from your phone by using this command.
adb pull /system/build.prop C:\Users\[your-username]\Desktop\
8. Launch the build.prop file in a text editor like NotePad++ on your computer, and add the following code to it.
persist.service.adb.enable=1
persist.service.debuggable=1
persist.sys.usb.config=mtp,adb
9. Save the file and transfer the file back to your device using this command.
adb push "C:\Users\[your-username]\Desktop/build.prop" /system/
10. Reboot your device using the following command.
adb reboot
11. You are all set. Your phone will boot up with USB debugging enabled.
