Help to unlock tab 7a - Samsung Galaxy Tab A series Questions & Answers

Hi all
I bought a tablet from some suspicious persons. New in box.
At home, I found that the tablet was locked by the system administrator and I can’t go further than the settings.
I read on the forums that I need to flash, but I can not enable usb debugging. What can you think of?

[Q] Nexus 7 (2012) Bootloop NO USB DEBUG

I have searched high and low for a forum where the same problems are presented. I have had no luck at all. So, I hope that I'm not driving anyone nuts here, but here goes
I have a 2012 Nexus 7. I am using this tablet to learn all about how to work with android software, ROMS, kernals, etc. It is unlocked and rooted. I have TWRP. It is currently stuck in a bootloop (I tried to install a custom ROM) and I have no idea if USB debug is on or not. When I connect the tablet to my PC, it will charge and the computer acknowledges that SOMETHING is connected but will not find the tablet itself. (ie: I cannot find the tablet icon to click on). I have been to dev manager and I cannot find it there either.
I have no idea what anyone is talking about with this abd sideload. Most of what is said is greek to me. If someone would be willing to explain that to me (in english) I would love to learn.
Obviously, I am in above my head and I really could use some genuine help here.
I just want to flash this thing back to stock. Could someone please explain to me how to accomplish this?

You need to read first. Then flash. If you kill your device then you won't learn too much. Start with this thread --> http://forum.xda-developers.com/showthread.php?t=1907796.
You will probably need to install the naked Android fastboot drivers (search!) to proceed through the thread, since you can't put the device into USB debugging.
Anyway, to answer your questions:
adb (Android Debug Bridge) is a tool that allows a computer to control low-level features of an Android device. adb sideload allows you to send an app or ROM from your computer to your device (usually in a custom recovery) and install it, which helps if you've accidentally killed everything on your internal memory. However, you need a custom recovery (CWM/TWRP) to use adb sideloads.
You're better off learning how to use fastboot, which is a bootloader-based tool that helps a lot with disaster recovery.
Okay, I guess I need more help. I don't understand how I am supposed to be able to use fastboot to bypass the "enable USB Debugging". If I could get this to happen, I believe I can get my device back to stock. Can you explain this to me? NONE of the descriptions online are of any use at all.
Just reboot your device using power boutton and volume+ and volume- buttons to access to bootloader mode I suggest you to use nexus root toolkit it's very simple and usefull

Nexus CANNOT ENABLE USB DEBUGGING
Can I ask for your help guys? My Nexus 7 v1 is stuck on boot loop (either stuck on google screen or sometimes would proceed up to the nexus animation screen) and I've been trying to fix it with the Nexus Root Toolkit (NRT). I just have problem proceeding with the steps since the toolkit advices me to enable my device's USB DEBUGGING (open device , go to settings, then developer options etc) which I CANNOT POSSIBLY DO COS AGAIN, NEXUS IS JUST STUCKED ON BOOT LOOP.
Can you suggest OTHER ways I can enable USB Debugging in Nexus 7? I would greatly appreciate your help.
You don't need to get into USB debugging mode, as your goal is to reflash a stable ROM onto your device. You can do that with Fastboot commands when your N7 is in the (unlocked) bootloader. You can follow the instructions in the second thread in this forum, or tell NRT you're soft bricked, to install a factory ROM.

Alternative method to access locked phone w broken screen?

Hi, thanks in advance for helping.
This is the situation.
I want to backup as much as possible items from my phone since it's broken, but:
- The screen is broken
- Device is locked
- USB debugging is DISabled.
I already searched a lot and tried the cmd adb commands to unlock it, but since usb debugging is disabled my device is not found..
I also tried to unlock my device using findmymobile, but somehow it won't unlock it.
I am now able to get Kies to recognize my phone (using recovery mode) and Kies of course noticed my device is locked.
Before I go to the store and buy that OTG cable, I was wondering if there is any way to change the registry of Kies and trick it into thinking my device is not locked. Sorry if this is a really weird question to ask.
OR is there any other way I can unlock my phone from my laptop? I know the pin code, so that is not the problem.
Thanks in advance.

Turn debugging ON with screen broken

Hi,
So, my zte blade digitalizer broke...
I still want to control my phone so i can install some apps, and to do so I found a tool here in XDA to control the phone in my computer, but the thing is that I didn't have the debugging ON before the screen broke, and the tool needs the debugging on to send the "controlling codes" to the phone.
While I was trying some options I found on the internet, (none worked) I removed the ROM that I had (cm10), and that gave me an idea.
Is there a way to "edit" a ROM and make the debugging option ON by default?
Or if anyone has any other idea please let me know!
Thank you.

Joying 7 - 2GB - USB Debug

Hello Everyone,
I' ve looked through the forum, and have had issues finding an answer to my question. Is there any way to get USB debugging working for ADB? I have tried everything i can think of, and am only able to get it to work in host mode.
My head unit is already rooted, and i am willing to make changes to accomplish this.
Thank You

Go into the Settings->About tablet -> buildnumber
Tap the build number 7 times and you are in developer mode. Restart the Settings and you can enable the usb debugging.
I wish it was this easy. I've tried all of the normal methods without luck.
