[Q] Need to auto-boot on power - suggestions?? - Galaxy S III Q&A, Help & Troubleshooting

Hey guys,
I've been given an SGS3 (I9305T) with a dead screen. I've managed to gain access via an 11-pin HDMI cable, and then from my laptop using Mobizen which gives me access to ADB.
I'm attempting to use it as a reversing camera; which is proving surprisingly effective! however, I need to be able to restart it on power connected (should it ever go flat)... and I'm stuck for options.
I would have tried 'fastboot oem-off-mode-charge 0', EXCEPT for the fact that fastboot isn't enabled on Samsungs :/
Is there any other options available that might enable this feature? Alternate kernel? build.prop mod? This detailed LG attempt??

[Q] Turning on Debug mode without touchscreen?

Here is my problem: I have an Atrix 4G without a digitizer attached. I can boot up and get to the lock screen.
Unfortunately, I am stuck in the USB/MTP mode. I would like to be able to get to debug mode so that I can ADB in debug and access my android homescreen with Android Screencast.
I'm hoping that once I do that I can begin to set up my Atrix to be able to use it solely as a webtop via the webtop via HDMI hack.
So here is my question(s): Is there any way to use ADB shell in USB/MTP mode to turn on debug mode? Or, if that is not possible, is there any way for me to unlock my phone/navigate around the home screen without a digitizer using either a USB or wireless mouse?
Thanks for your help,
Jon
Did you get a reply??
Hi Jon...did you get a reply to this query? I am also trying to switch debug mode on "hands free" for a different reason, but would be very interested to know if anyone gave you a tip on how to do this.
I want to auto install software onto devices but cant do this until the phone gives me control of the USB connector...this doesn't happen until debugging mode is switched on. This means I have to go through the menu to switch debug mode on, then I can install the app. OK for one phone...but I need to be able to do this with hundreds of phones a day!! Lots of wasted time going through menus.
Hope you can help or point me in a good direction?

[Q] Rescue S3 with broken display and digitizer and without USB debugging

Hi guys!
I have a Galaxy S3 with broken display and (MHL tested) broken digitizer.
Device works, I get home screen but can't unlock.
I would rescue the smartphone and I think that the way is using ADB (with [email protected], screencast or similar).
I don't have alternatives right?
The problem is that I can't use ADB cause actually it does not have USB debugging enabled.
Just a couple of questions:
Can I use ADB in recovery mode (without USB debugging)?
With MHL I get broadcast in home screen, not before, is that normal? How about MHL in recovery mode?
I can only imagine a solution: Go in recovery mode and execute a "no-look" change of ROM installing something with USB debugging option enabled by default.
Do you have other solutions?
Who can help me doing this? Does exist a "how-to" somewhere? Which ROM?
Thanks!!
Hello,
i had the same problem, i could solve it. Here is how i did it:
Click.
I first had to root the phone and also get a recovery on it (i think it enabled ADB).
The problem is the broken digitizer. You can't use the USB-Debugging because you need to confirm a popup from Android (i think it depends on the Version of Android).
Hope it helps.

Help needed! How to root a cracked screen Z Ultra?

Hi,
My Z Ultra's screen is cracked and i would like to use it for my TV as a Android-Box replacement, because it's actually still usable i think. Now my Problem isn't finding a suitable Rom(i think) or general knowsledge about rooting.
I think i got all the needed tools like a microsoft bluetooth keyboard with touchpad(regular usb mouse and keyboard too if needed), a MHL/USB(all-in-one) OTG adapter, HDMI cable and the universal USB micro to usb adaptercable.
SO my questions are:
1) Can i root without actived USB Debugging? (i can't activate it due to the cracked screen) ...Most important!
2) Is Towelroot still good? Or are there other easy root methods for newbs?
Thanks for reading any maybe helping

I am testing now and mouse works fine with developer options and USB debugging turned off.
Does your phones screen display? I also reread your first post ", a MHL/USB(all-in-one) OTG adapter," the OTG cord I have is just a male micro and female full size USB.
Yes the screen seems to display. i tried it with the z ultra and oneplus one, both didn't respond to a mouse(two different tested with two different otg cables). I still got the S4, will try that on it too later.
Basically you plug it in and you see a mouse cursor or what? i clicked around, but nothing...
Also on my Z Ultra the widget on the screen seems to jump around, just like the stars that move when you touch the screen usually if you get what i mean.

Yes I see a cursor (even on the lockscreen) and it does give the shooting stars effect when swiped. Needed to hold down left mouse button when swiping and then release.
my shooting stars "cursor" seems to either jump around or not appear at all, but nothing happens.
Does anything pop up on the top down menu or does it play sound when connected?
Would this from this thread work on the XZU too, due to it being android based?
Reset Nexus into recovery mode (power & volume down)
2. Connect to PC via USB. Install the USB driver from the SDK so that it appears as an ADB device
3. Fire up the updated toolkit. You should see the nexus as a fast boot device
4. Unlock bootloader
5. Using option 10 on the toolkit load up CWM on the phone. This gives you ADB access so can you pull files off the device via ADB although I could access the SD card through programs like Droid explorer.
6. If you want to carry on further and get into Android properly, you'll need to wipe the cache from within CWM
7. Reboot and hold down the volume key to get back into recovery
8. In the toolkit select root options (option 4) and load temporary image (6) If it hangs on the google or nexus logo you've not wiped the cache.
9. With this second phone I couldn't access it through droid explorer as it was popping up as an MTP device but I could pull the files via command prompt or through the toolkit
10. If you have any use of the touchscreen at all you can run the following command which will then mean that any touch will unlock the device
adb shell rm /data/system/gesture.key
11. You can activate bluetooth via adb if you have a mouse or keyboard available but you will need to be able to press okay on the screen
12. Any changes you make in the unstable android image such as lockscreen, bluetooth, enabling debugging, etc will remain in place when you restart the device.
13. You can relock the bootloader if you wish via the toolkit. You just need to be in recovery mode first.

I have no idea if any of that would work, to me it sound like a lot of it would only apply to Nexus. I checked and the only indication I have that mouse is connected is the scroll wheel lights up. I had three apps that I thought may remotely effect mouse so I uninstalled and rebooted and it still works. I also looked through all the settings menus and can't see anything there.
Is there an app mybe, that would set USB Debugging automatically to enabled just by installing it? I can load apps from playstore to the device
Or do fastboot or recovery mode provide USB debugging enabled?

Or try another mouse, or something because I was able to control via mouse. Here in the states we have a two hour window for refunds, but it is already late here and I should be sleeping or I would offer to test. Here is a YouTube video that shows it working the way it works for me.

bought it, but it still needs usb debugging enabled in order to function -_-
thx at least now i know how it SHOULD work :laugh:
it seems i can't use adb driver because this once again needs some android setting enabled.
weird thing is right now that i somehow got into some menu beyond the lockscreen, but still cant do anything :crying:
so close, but so far at the same time
I'm about to buy a fire tv or some other android box and throw the XZU away as it seems its useless in this state without zsb debugging

I am 99% sure that OTG mouse should work without USB debugging enabled.

How old is your Z Ultra? The reason I ask is people have reported very mixed results as to getting screens replaced under warranty. I think I even recall someone who wasn't the original purchaser getting a screen replaced for no charge.

broken screen: recover data/change usb settings/getting device recognised by adb (?)

Hi,
i broke the Display of my ZTE Axon 7 mini on stock ROM and without USB debugging enabled. No custom recovery or anything done to the device. The touch interface of the screen is at least partially functioning, i'm able to boot it, unlock it by guessing where to draw the pattern (i know bc the fingerprint sensor is working afterwards) and power off as well by clicking on the spot where the button should be. I've read some threats about tools to access your phone with broken screens, but nothing worked. Thing is, i think i set the usb-setting to "charge only" when connected to my pc. So the device won't be recognizedwith adb fastboot. Which means i cannot use the method described here for instance.
So does anybody know how i could change the settings or get at the data generally? I'd be really glad if someone could help.

Rooting the G8 Power via OTG (without app, or PC)

Hi,
I'm currently interested in the question, if I can root my device without any PC or an app, because I momentarily don't own an PC, apps are mostly not able to root the device and interrupt in the middle of the process.
So shortly said, I have an Lenovo Tab M10 FHD+ and want to connect it to my Motorola, to enable root permissions on the Motorola phone with the app linked down below.
The only problem is, that I already connected it via OTG, but commands like reboot work, I was actually surprised, but as soon as I start going into fastboot mode, the device detects the phone, but not the app and no data transfer between the devices is being enabled.
- USB Debugging option in the developer options was enabled during the process
- OEM Bootloader Unlock option was also enabled
I even tried wireless debugging over WLAN, but problems like an endless loop while connecting, occured.
Can anyone help me getting the right commands for the app?
Link of the ADB OTG shell app, I'm using:
ADB⚡OTG - Android Debug Bridge - Apps on Google Play
⚡ Run ADB commands without a computer [No Need ROOT] ⚡
play.google.com
Have you fully unlocked the bootloader?
