[Q] adb device offline - broken screen - General Questions and Answers

Hello!
Today both the screen as the touch panel of my Galaxy Nexus broke. I wanted to run screencast or some other apps to control my phone via pc BUT after searching for "adb devices" I got my devices number and the word "offline".
I looked up on what I guess the issue was and what I found out was, that I have to verify my pc with this RSA-fingerprint in order to control my device, which I have not done yet on my latest rom, as I just flashed it a few days ago.
Now: can you think of any way, either bypassing the fingerprint or letting me control the device via pc to prompt the fingerprint-request?!
As mentioned, I THINK that is the problem.
Things I have tried:
different USB-port
different USB-cable
updating platform-tools
HDMI-output via MHL-adapter (no signal)
I really am hopeless and happy about all the ways, you could think of showing my phones screen on my pc. I would prefer to keep my current ROM data, as I do not want to wipe arrived messages before viewing them (WhatsApp).
some information:
device: Galaxy Nexus (GSM)
rom: latest AOKP Milestone (4.2.2)
root access of course
device definetly turned on (LED blinking)

Resolved!
I had a similar problem and after hours of research and trial/error, I was able to get this working. Here's how:
1. Download & install the Galaxy Nexus Toolkit and MyPhoneExplorer to your PC
2. Goto the Google Play Store on your PC and remote install MyPhoneExplorer and AF Rescue 2 apps to your phone. Wait 10 minutes or more so that this step has time to complete before continuing (longer is better)
3. Next you have to boot your phone into Recovery mode... pull the battery and usb cable out (so you can be sure your device is off). Put the battery back in, plug in the usb cable (I do this now so I can hear when the device is connected and later so you can hear that the command/reboots are working). hold down both vol up and vol down AND then hold down the power button... I do this for about 10 seconds. After releasing the buttons, your phone should be in bootloader mode, but I give it a minute just in case. now hit the vol up button 2 times then the power button. You will hear the usb connection go on and off several times and when it's done, your device will be in Recovery mode.
4. Launch the Toolkit, answer "no" to the initial question about checking for updates, then choose your device from the list
5. on the next screen (main menu) you should see your device ID listed under ADB mode list with the word "recovery" after it. If so, you have done everything correct so far. (if not, close the toolkit window, go back to step 3 and try again).
6. Next choose option 2 for Backup/Restore. Then select option 3 for "Backup your Internal Storage"
7. This is crucial. On the next screen choose option 2 "manually answer the question". Then when it asks if you are using a custom rom or recovery image, ANSWER "NO" (even if you are). This is the most important step in the whole process because it will then boot your phone into fastboot for you and install an insecure recovery image bypassing the 4.2.2 security!
8. When it tells you that the backup will take a long time and are you sure you want to continue, I recommend doing so. It will take hours (I left mine to run overnight.) Either way, when you get back to the main menu DO NOT REBOOT YOUR PHONE. YOU NEED IT IN THIS STATE.
9. Now if all has worked properly, you can launch MyPhoneExplorer on your PC and choose setup your connection via wifi. Cross your fingers, but if all worked as it did for me, your phone will appear on the screen (if it is all black, just hit the power button on your phone to wake it up). Use your mouse to enter your lock pattern or pin number if you have those set. At this point you should be using your phone through your PC. Just remember that as soon as you reboot the phone, it will revert back to it's secure state and you will have to go through this process again. I hope this helps you and others (and saves everyone the hours of frustration and research I went through).

Thank you very much for your time and effort, I will try this soon!

Sadly I am in the same position as the OP. My screen is cracked and I need to access the phone via adb, unfortunately, it is appearing as offline. Does anyone know a way to bypass this RSA-fingerprint issue?

[Q] How to connect over ADB when "USB Debugging" is diabled

OK, so here's the issue. I have an HTC Desire C. It's my girlfriends so I don't know the OS version. I replaced the Touch Digitizer because it was shattered (it did respond to touches though). Now that its replaced it seems to respond to touches but not correctly. I can't get it to swipe the lock screen out of the way. It's as if it is not calibrated correctly. So I'm stuck on the lock screen.
I want to run ADB so I can figure out if its registering touch events correctly, and also try and send them over ADB. But, being my girlfriends phone, she never enabled "USB Debugging". When I hook the phone to the computer, I don't see it showing up as a unknown device in windows Device manager (VISTA). I know it works, cause I tried it with my Nexus S and that shows up. I know the steps are first find it in device manager then manually select the driver as the ADB interface, I've had this working on my Nexus S. But the issue is that it doesn't show up at all in Device manager, and I assume its because USB debugging is off. I tried turning off USB debugging on my Nexus S, hooked it to my computer, and it doesn't show up either. So it seems like that is the issue.
I tried to boot into recovery (power button + volume down), then went into fastboot, connected the phone to the comp again, but it still does not show up.
Below are some of the other things I have tried, but they still brought me no luck:
I have tried installing HTC sync so I get the HTC drivers on my computer, but it doesn't even show up in HTC's software (In fact, it does not show up as a storage device either, I assume cause you have to accept the notification on the phone, but I can't use the phones UI at all). I tried moving the HTC drivers into c:\windows\system32 and it still does not show up. I then tried rebooting the phone and my computer. Still does not show up. It seems like windows isn't even reading the phone as a USB device. Tried swapping USB cables (both work with my nexus s), and still nothing. Is there something I am missing?
Any help would be much appreciated, this is driving me crazy.
Also, after replacing the digitizer, if I first boot into the phone and then hit the power button, I don't get the content window that allows you to choose "reboot", "shutdown", etc. The only thing I can do is hold it for 15 seconds and the thing turns off. I'm hoping this is because I never passed the lock screen for the first time. I'm hoping this is not an indicator that I screwed something up when I opened the phone. I've had my Nexus S open plenty of times.
Another guy had same issue. here
Try that.

Yea let us know if it works

I can't get the phone to show up when I type "fastboot devices" or "adb devices". I have tried this from the lock screen, from the bootloader, from the bootloader and in fastboot mode. That is my critical problem now. Cable is actual data cable, and I'm using USB port on back of a desktop computer. Is there anything else that could be causing the phone to not be recognized?

Need To Restore Nexus S 4g

I have an extreme problem with my Nexus. I've been through thick and thin with this phone, and I'm hoping you guys will help with a solution to this problem.
The power button to my Nexus is broken completely. I stabbed it so much that the clicking black part is completely removed from the slot (on the motherboard).
One time, my Nexus S died, and I realized I had no way to turn it back on. I tried every single method (battery pulling, button pressing, USB connecting, etc) with no answer. I finally was able to find a solution. I used Odin to restore the bootloader tar md5 file, and thus auto rebooting the nexus (when the box is checked). This worked like a charm, until I realize I made a fatal mistake.
I chose an md5 file for the ORIGINAL Nexus S (not 4g).
I was able to easily go into recovery with Quick Boot from the Play Store. I installed Raspbean Jellybean (02-05-13 build), but the installation was very faulty. The home button is nonfunctional (it vibrates when pressed, but nothing happens) and Browser is not working as it just closes itself instantly. Like an idiot, I didn't install Gapps before rebooting into the ROM.
Stuck in that dilemma, I used the built in email app to sync my Gmail account to the phone. I sent a Quick Boot APK to myself to try and open so I could reach recovery, but it said there's no type of program that can open that file (maybe because Gapps isn't installed).
The last thing I tried was Odin again. I tried to restore the ICS release keys, but Odin will not recognize my phone anymore for nothing. I tried 3 different USBs (2 with shorts, and 1 normal one. I don't know if the type of USB has anything to do with it). Nothing.
So here I am with a faulty, Gappless ROM on my Nexus S 4G with a completely broken power.
I'm wondering if you guys have any solution/suggestion to get Odin to recognize my phone again so I can restore it and work from there.
Apart from that, ANY solution to this problem is highly acceptable and greatly appreciated (ways to get into recovery, etc). I don't want this to be the last of me and my sweet ole Nexus =(,
Thanks x1000 XDA!
Hey Guys. I was actually able to reach recovery, because the ROM I'm using has a Power Menu widget in it's quick settings (Go Figure). But my phone is still unable to be recognized by Odin in Download mode. The phone is also not recognized by my pc at all. It only charges, no matter what USB I try. I even tried mounting in recovery, no go.
Please help. Thanks!

Stock TF700 boot loop, can't turn off device.

Back in June, I turned on my TF700 with the dock attached, it started as usual.. I turned on my wifi, opened up my browser to look up plane tickets, then it restarted. I didn't think much of it, and when it loaded up again, I tried to look up tickets again, and it did the same thing. I gave up, closed it and zipped it up in my sleeve. It was a few hours before I got home, and when I took it out of the sleeve, it was quite warm! It was constantly rebooting and there was no way to turn if off. I left it out of the sleeve and let the battery die. I didn't use my tablet for a few days, and when I went to turn it on again, the same thing happened, and has been happening ever since. I have tried to start the tablet while connected to the dock, the wall charger, without the dock, with wifi on, with wifi off, etc. The tablet gets to the lock screen, I unlock it, and I only have about 10 seconds before it freezes and restarts. I am unable to turn off the device, because when I choose "shut down" from the menu, it shows that it's in the process of slowing down, but then the spinning wheel freezes and it vibrates and restarts before it can fully shut itself off. Since I can boot into android, I thought it was something that the tablet is trying to run upon startup that was causing problems. I was able to quickly get to settings and apps, to uninstall several apps, but nothing has helped. I used to have a task manager widget on the home screen, and uninstalled that too.
After doing research into the problem, I found that most people who have boot loop issues or constant restarting, are rooted and are experiencing difficulties with a new ROM. I am 100% stock. I have held down power and volume down. It gives me RCK, Android and Wipe. I have tried cold booting into android, but the same restart loop after 10 seconds occurs. I thought it might have been a bad firmware update that went through unbeknownst to me. So I downloaded the firmware file from ASUS, renamed and flashed it sucessfully. However, no change in the reboot problem. I am running the following version: US-epad-10.6.1.14.8-20130514. I know there's a new version out, but wasn't sure if I should try to flash that yet.
I am willing to try absolutely anything to fix the problem, with the EXCEPTION of wiping data. I know that would be the easy way to go, but I have photos and videos from my best friend's engagement and they are the only copies. If I am able to get my tablet to be stable enough to copy those off, I would then be willing to wipe and have a fresh start. I have tried connecting my tablet to my computer, and it is recognized. After it boots up and I unlock it, then the tablet begins to mount (I'm on windows 8). However, I still only have 10 seconds or so before the tablet restarts, and that's not enough time to even view the folders from the tablet.
It's been 3 months since this started, and I have done lots of research and tried lots of things, but nothing has helped yet. Since I haven't delved too deeply into the dev side of android (I've only rooted my S3) there is lots of android speak that I don't understand fully, or have experience with, like ADB. If someone is willing to offer suggestions on what to try, I am very good at following directions! Thank you for any help or leads you can offer.
Wow - you're in a difficult situation...
You being on stock I can only imagine the bootloop is caused by something you installed.
So if you can access settings and are able to uninstall apps, just keep doing it until you are back to the original stock setup.
Are you sure the files you are trying to save are still on the SD card? Don't know how you flashed 10.6.1.14.8, but flashing a complete firmware package ususally erases /data - although your persisiting bootloop indicates it didn't...... if the bootloop is caused by an app. And I can't imagine what else would cause it.
You could try to do a factory reset in Backup&Restore but you will loose the contents of your /data partition...
You can flash the 10.6.1.14.10 firmware file, but most likely you will also loose your data.
The only way I can think of to replace your bootloader and firmware without data loss is if you try to find a copy of the 10.6.1.14.10 dlpkgfile. That is the OTA update file Asus pushes out to users. It's a patch file, meaning it only replaces/updates new files and leaves everything else alone.
If you find the dlpkgfile on some forum you would have to place it into your /cache directory and reboot - and I don't know if you can copy it to your tablet before it bootloops again.
Unfortunately the reason for your bootloop is probably an app on the same partiton with the data you don't want to loose. Unless you manage to uninstall the culprit I don't see much hope....
Good luck!

Try getting adb access, this should allow us to diagnose the problem you are experiencing.
Tablet side: go to settings, developer options (if it is not visible, tap the build number 7 times), enable USB debugging
Computer side: no idea, they say Windows 8 is a bit tricky to get the drivers installed correctly.
When you have adb running, do "adb pull /proc/last_kmsg" and post the downloaded file - it should contain valuable info about your reboots.

He's bootlooping..... How does he go into settings and turn on USB debugging?
I think the best option maybe to flash a stock Asus ROM from their site but that will wipe all data including those photos......

I have not use this method but you could try.
You need a boot OS tool on your external sd and run it from your external sd so you can access to your internal sd to copy files from there. You can search on the internet and you should find more information on how to use them depending on what boot os you are using.. Good luck.

I was actually able to get usb debugging turned on. It took me quite a few tries, but I did it!
I've never used adb, but here's what I've done so far.. I downloaded the Android SDK and ASUS Pad PC Suite (which contains Asus Sync).
I was able to use the command prompt to navigate to the platform-tools folder and open adb, however when I type in adb devices, it doesn't recognize my device. What steps to do I take from here to be able to use adb to see my device, so I can pull the file to diagnose what's going on? How do I know if I have the right drivers installed so my computer can see my tablet? All I did was install the asus suite. Do I need to do anything further on that end?

What Windows version do you have on your PC?
You can check your drivers in Device Manager. Open it, look for your tablet under Portable Devices and check if the driver has a yellow exclamation mark next to it. You should be able to update/install/uninstall the driver from here.
Try to find out if there is a setting in your Windows version to only allow Microsoft signed drivers and disable it.

[Completed] Screen inaccessible(no display) usb debug disabled cmd help

Nexus 5 running 5.1 stock
I had recently and sadly had an accident with my phone where the screen is completely useless. Shattered is a harsh word, but it's sitting in that condition. It does however still turn on. There are parts of the screen that display, but for some odd reason, its completely mirrored and upside down.
I have Android tools and drivers installed. And knowing something like this might happen, I had USB debugging enabled. BUT, for even stranger reasons, I'm guessing it's disabled because through cmd on platform-tools, it says it's unauthorized. Though the little window of display my phone pushes, I'm guessing I'm getting a dialog asking for USB debugging to be enabled. I'm not too sure how I got to this window, but it randomly appears on restarts of the device, and half the time, it just restarts normally like any restart.
I was wondering if there was a way I can push a command line using cmd on my PC to accept or continue from the dialog box that I literally can't see.
I looked far and wide on Google and this beloved website, but am having a hard time finding a solution.
The device is bootload unlocked, running stock on Lollipop.
I do not know if rooting and installing TWP will affect my data, as it is the only thing I really don't want to lose. I wish to keep stock as I am completely fine with it and I have tried custom Roms, but I still wish to continue using stock.
I'm not too familiar with some words used in explanations on this site, so please respond as if I'm 7 years old :silly:
My initial goal was to (while having usb debug enabled) fastboot (i think i'm using the right term) Mobizen, then mirror the screen on my pc, and control the device to upload everything to my cloud storage.

Frozen Screen; Retrieve Pictures?

Out of nowhere my S6 stopped working. Each time I restart my phone it gets stuck on the "LTE Plus" screen. I need to figure out a way to retrieve my pictures/videos. I didn't back them up. I checked my Samsung, Google, and One Drive accounts. Below is a list of things I can still do on my phone and things I've attempted. Let me know if you have any ideas.
1. I can soft restart my phone
2. I can restart it into download and bootloader mode
3. I can not start it up in safe mode
4. I wiped cache partition
5. I can connect it to my laptop via USB but it only shows as a bluetooth device. It does not show any options to open up files. The phone was not debugged prior to the phone breaking.
6. I've tried trial versions of Fone Lab and 2-3 other similar programs. Each time with no luck.
Would love to hear your thoughts or ideas. I really don't want to lose these pictures/videos. Thanks!
