[Q] Restoring to stock with no screen and USB debugging not enabled

Well, I'm in a bit of a predicament.
Last week I installed a custom rom, and almost immediately after, I completely destroyed my phone's LCD and digitizer. Fortunately, the phone still functions fine, but obviously I have no screen and I can do nothing except essentially press the home button. I still hear text message tones, etc, and I can still call the phone, but obviously I can't navigate or do anything as there is no screen.
The problem is, I want to sell the back of the phone as used parts since it functions well, but the phone contains sensitive information (my contacts, SMS, etc) that can not be accessed via Windows Explorer.
I downloaded the SGS3 QCom Toolkit, but it will not recognize the phone, nor will Android Commander, because USB Debugging is disabled.
I'm not interested in retrieving anything in the phone, but I definitely want to delete the SMS, contacts, and Google login info from the phone. If this means restoring factory and loading stock rom that would be great, but I can't seem to do anything without USB debugging enabled, as no software seems to recognize the phone even with all the drivers installed.
Can anyone help? Thanks in advance!

[Q] Problem with Galaxy Tab 7'' update

Hello.
I recently got myself a Samsung Galaxy Tab 3 7in and everything seemed to be working just fine until the system eventually prompted me to update the Samsung software. I followed the steps, the tablet downloaded the update files itself and rebooted in order to install the updates. Problem is, during the reboot/installation process the screen remained black with just 2 lines of pixels on across the screen, I though this was part of the booting process but it just stood there for more than 10 minutes so I decided to turn it back on. Everything seemed to be fine, but then an error message came up saying there could be problems with the software (i didn't pay too much attention), but after this it won't let me install any apps. After an app is done downloading a message pops up saying "unknown error code during application install -110", plus my computer (or any other computer) doesn't detect when it's plugged in via USB cable. I've tried doing several factory resets and wipes and still have the same issues. Tried installing Kies but it won't detect it either.
How can I repair the firmware without having to connect the tablet to my computer? Is there anything I can download directly to it or transfer via Bluetooth to re-install the software?
Any help will be very much appreciated

Try resetting it back to factory defaults. You can google it easily.

my friend has the same problem. did you fix the issue? if so how?

I am using the Apex Launcher but I think this is possible with stock launcher as well hopefully it helps someone. This is one way to do a factory reset is:
You will need your MSL TO DO THIS. If you don't know it put the "Factory Mode" shortcut on your home screen then skip down to the 2nd part of this post & install the msl app.
FACTORY RESET:
1) long click on the home screen
2) click on shortcut
3) select Activities
4)Scroll down to "Factory Mode" tap it then select the dropled down one. This will put a Shortcut on the Home Screen.
5) Find the Factory Mode shortcut you just made & tap it to open it.
6) Dial ##786# then on the screen that pops up
7) select "RESET"
8)enter your msl in the box that popped up then select ok then the device will reboot & when it powers backup it will be like it was from the factory & if you don't know your MSL follow the instructions below.
TO GET MSL:
1) In a browser type bit.ly/mslutility - can sideload if needed
2)install app
3) Open app & click get MSL it will most likely fail this is fine.
4) click on the factory mode shortcut you made to open it
5) dial ##3282# & put in 6 zeros-it will tell you that it's incorrect this is fine. Go back to home screen
6) Open the MSL App & click on Get MSL-this time it should give you your devices 6 digit MSL Code. Write it down. Then do step # 6 above to reset your Device.
This shortcut will allow you to put the Sprint SGT3 into DIAG MODE(##3424#) , get into the ##data#(##3282#) menu, do the factory reset ##RTN# (##786#) & most likely any other Dialer/hidden menu's for this device.
Thanks to the MSL App builder(not sure who it is so let me know please)

[HELP] "Android system has sttoped working" loop 2 seconds, unable to use screen.

[HELP] "Android system has sttoped working" loop 2 seconds, unable to use screen.
Hello,
Lg g3 (Telefónica / Movistar branded Spanish carrier)
Bought in Jul 2014.
Weeks having reset problems, one day, on a reset, got the msg "Android system stopped working", close, 2 seconds, again same msg, I can't use ths screen to avoid it, just to close the msg window, neither to browse options in those 2 seconds in each loop. I can only use the turn on/off buton, so, when I reset, same stuff again..
I tried to use Recovery Mode (vol-) and I just get the option to restore and WIPE ALL INFO (even files, pics, etc..)... no more options
Tried Lg Suite + Download mode (I can enter in download mode) but the software don't recognice the device.... using original cable,
I need the stuff inside, don't care about the phone thou, will get a new one, but I really need the info inside (no SD, the info inside the internal storage).
Any help?

If you turn off the device, hold down power and volume down. Release them when the lg logo shows then immediately press them again you should get to a factory reset screen. Try performing a factory reset, this will not wipe your files, just all apps and app data

Hi,
thanks for the answer.
that was my first hint, but, as you can see ( imgur.com/ d31OXJi) that menu option says "Delete all user data (including LG and carrier apps) and reset all settings?"..
I do belive this is warning me about wipe all my data including pics, videos, contacts, etc...
Are you 100% sure that wthis will not wipe the entire information?¿
Thanks...

BUMP!
Can anyone help me or confirm us if I do the vol down restart to factory will wipe my pics away??
Thanks...

Really? Noone ever have restored the phone using this option on a g3 to know if the pics will be deleted or not? amazing...

Backup non-rooted LG G4 stuck in "UI stopped working" loop

Hello everyone,
Yesterday, after I tried to charge my LG G4, it stopped booting properly: it seems to boot "normally" under the hood, except that the system UI is not properly loading so instead I get a black screen and a message "Unfortunately system UI stopped working". If I click "ok", it comes back within two seconds (the screen stays black apart from the error message). I cannot do anything, like unlock the phone or access anything on it, despite the fact that I can hear notifications coming in.
Unfortunately phone is not rooted, developper mode isn't enabled, and I don't have a custom recovery. I would do a factory reset if it weren't for my Google Authenticator codes, some of which I haven't properly backed up like an idiot. Thus I was wondering what I could do to back up my phone or solve the issue.
Here is what I've already tried:
Press down VOLUME DOWN + POWER to enter recovery mode, but since I don't have custom recovery this only gives me the option to do a hard factory reset and lose all my data.
Use adb commands to access my phone, but I get "unauthorized device" because I haven't enabled developper tools on the phone.
Use the app "LG Bridge" on my mac, but it also doesn't work for the above reason.
I see three possibilities, but I don't know whether any is genuinely doable:
Solve the issue of the error message, which from what I've read requires me to wipe the cache. But how to do that without custom recovery?
Somehow bypass the UI to unlock the phone and unable developer tools
Manage to backup the phone from my computer while its locked without developper tools enabled.
Note that obviously this is my phone, I know my passwords, I have access to my Google account, etc.
Any help would be greatly appreciated, without my Google Authenticator data I'll be locked out of an important email account.

Well at least you can backup your phone in download mode with SALT ( https://bit.do/SALTatXDA ) but restoring is another story.

Thanks a lot for your reply! I'll try backing up with SALT tonight. There are two things I'm wondering:
How do you think I could extra data from the backup?
Will I be able to wipe the cache or enable usb debugging with SALT? That might solve the issue.

You can mount the userdata partition on Linux (e.g in FWUL) and then browse through it like it's on your phone.
You can wipe the cache paetition in SALT yes. It's in the advanced menu there (erase partitions -> select cache and only that). It will not wipe the dalvik cache though.
I dunno about the USB debugging though. Maybe there is a way but if so you would need a very unrestricted download mode (depends on model and firmware). And the whole process is not easy.
It requires again SALT and there you have in the advanced menu the option to open a shell.
Here you can mount userdata with
mount /data
But it's usually mounted already. Then it's a try and error. You could e. G. try to delete the dalvik cache etc.

Hi!
I've found out that the Google Auth keys are in /data/data/com.google.android.apps.authenticator2/databases/databases. So I need to backup /data/. However, when I show the list of partitions with SALT, I don't see /data/. Is there a way to backup /data/ on my unrooted device?
Secondly, I haven't managed to wipe the dalvik cache with the command shell, would you be able to point me in the right direction?
Thank you so much!

OnePlus 3 not starting anymore

Hi,
I'm running a current Stock-ROM on my OP3, as provided by OnePlus OTA, never flashed something else. Just using the phone out of the box.
Yesterday, I deleted some cache data to free some space on my 99% filled up phone. Then I opened the gallery but not all thumbnails appeared and then it stucked completely. I holded the power button and it switched off. Now when turning the phone on a message appeared saying:
"The dm-verity is not started in enforcing mode"
After a few seconds it changes to the 3 animated points and this never ends. All I can do is switching it off, starting recovery mode or fast mode again with the same behaviour. I tried to connect it with my PC (W10) but it is not showing up.
How can I fix this problem without loosing my data especially my pictures and personal folders. How can I backup my data? I can still see them in recovery mode but how to access them and copy them? I could live with resetting the phone losing all settings and apps, but not my files.
What is your suggestion? Thanks in advance.

Ok, I just tapped on "Reset system setting", lost all apps and settings but it starts again and all my files are still there. Problem solved.
