Hi I’m trying to root my viewsonic iR7Q tablet, I’ve tried kingoroot on both versions and neither seem to work.
On the pc version, the tablet won’t show the notification telling me that the pc has tried to connect, and the app will just tell me to enable usb debugging, which is already active since the tablet warns me about it and asks me to turn it off.
Also on a side note I can't access the developer options from the configuration menu, I had to enter through the malware bytes app.
And the .apk isn't much help either, it will reach 90% then freeze the device, I waited for 10 whole minutes and no progress at all, it was still frozen (I read somewhere that I shouldn't take longer than 5 minutes) had to reset it.
It was connected to wi-fi so I don't think it was that, anyone know any way to root it?

Hi everyone, first, this is my first post, new to the forums, at least as a registered user. I have a problem with my phone. I know most of you are wondering why I have not just read the other posts on the forums, but I have. I have attempted every solution to the problem posted previously.
Background: Phone: Samsung charge.
I was being impatient and did not want to wait for the gingerbread update form Verizon. I flashed the leaked gingerbread 2.3.4 onto my phone using odin. Everything went great. I was able to use my phone with no problems except shortened battery life, but nothing major. About a month ago the battery life was impossible to maintain and there were some software bugs, like clicks during calls, startup taking forever, around 2 minutes on average!, and random restarts that never happened before. I decided to look up some fixes and found that verizon and samsung had released GB 2.3.6 for the charge. I got excited and decided I wanted to get that, but I could not via OTA. I read some forum posts and they mentioned attempting a factory reset on the phone then trying OTA update. I went ahead with factory reset and everything went fine. My startup time is around 25 seconds now and no random clicks or gliches, but still not on 2.3.6, which was the whole point. I then decided to just flash the stock 2.3.6 rom to the phone.
Problem: When I plug my phone in to multiple computers it will charge but not connect to the computer. This means on my Mac it does not show as an external drive, which it has in the past. On my windows 7 machine it says that drivers were installed but could not be used (I can get the exact quote if needed.) I attempted to go into device manager and solve problem that way but it shows my phone as "unknown device". I have tried to enter download mode when hooked up to windows computers and no connection is found.
Possible solutions attempted and their outcomes:
1. As stated, I attempted the method shown in a thread on droid forums for installing the samsung drivers. I have attempted multiple times to install the drivers on my windows machine and the device remains "unknown".
2. I have attempted multiple cables on multiple computers, both mac and windows 7. No change.
3. I have installed adb and attempted to locate devices using adb devices command on mac. No devices found.
4. I have attempted all methods with both usb debugging checked and unchecked.
5. I have tried every possible usb port I have.
Ideas/questions I have had that I have no idea are possible or how to fix!
Would a factory reset take away the ability to connect to a computer from my phone. So, is there a piece of software in the build I have that controls the connection between the computer and the phone, an identifier of sorts, which is now missing, now that I have reset the leaked ROM.
Is there a way to flash a new ROM without connecting to a computer, via the sd card, and what is that? I have read some things in other posts but am too much of a n00b to understand most of them when using sdcards.
ANY help will be greatly appreciated. PLEASE PLEASE PLEASE!!! I have been at this for at least 6 hours, sifting through forums, searching google, attempting fixes that others have stated worked for them, only to fail every time. Thank you all.
have you try on a different pc?
maybe on your PC there is some problem with the drivers.
Moreover to connect via
adb u must enable Debug mode on your device in the application menu.
To flash kernel or other directly from your sd you can use the clockwordmode, but to install it you must before
install it and i fear you must use your cable connection

I have tried multiple PCs and a mac, even windows on bootcamp. I have installed drivers on every one, even uninstalled and reinstalled on one. One PC, my laptop was a fresh windows install (it was a linux box but I needed windows to use Odin). I was in debug mode and not in debug mode when attempting adb. Thanks for the suggestions though. As I said, I have tried numerous things and am completely stuck! so frustrating!
"I attempted to go into device manager and solve problem that way but it shows my phone as "unknown device"
Exactly there... you can try to force device to install a different driver.
Double click the unknown device then driver then update driver then find software in your computer then choose manually from a list of device drivers in your computer then show all devices you should see "android adb interface" or something related to google or android.
Try it... i hope this can help you.
Hello everyone,
I'm in really deep mess right now.
My rooted (Kingroot) Nexus 7 (2012) WIFI with official Android 5.1.1 was working just fine but I wanted to tweak some things and people were saying that SuperSU has better app support (like Device control etc) so I said I might swap using SuperSU-me app. Before I never connected my tablet to a PC so it's not been verified by the device. But I did turn on the USB development option (7 times tapping). And I do have titanium backup of system and apps data but it's all in the tablet's memory I can't access from my PC.
What is the problem: After I ran the SuperSU-me it asked to reboot. Something went wrong because it stuck in bootloop. Accessing Recovery Mode only gives me only a "No command." note.
Nexus Root Toolkit and SkipSoft ToolKit can't recognize the device and I'm becoming desperate worrying I bricked my device for good.
I found no threads or articles on the internet with this specific problem. If you could help in any way, just sending a link to a discussion or any article or personal experience I'd really be more than happy.
Thank you for any replies, Hrnek Bezucha
A client of mine rooted his Galaxy Tab 10.1 and immediately lost USB connectivity; he could no longer get the computer to recognize his tablet in order to sync music, pictures, etc. I have verified the issue on multiple computers running both Windows 7 and Windows 10. I have also verified that the drivers on these machines are current, still to no avail.
In an effort to resolve the issue, I attempted to restore the stock firmware onto the tablet by putting it into download mode and using Odin to install the firmware. When it finished reinstalling, the tablet still shows a padlock symbol upon startup and still has no USB connectivity, which I can only assume means that the tablet is still somehow rooted. Can anyone confirm the meaning of the padlock symbol? Any suggestions pertaining to the next best troubleshooting steps? Have I perhaps gotten the wrong firmware? If so, where would I find the correct release?
I thank you all in advance for your insights and expertise.
So i got my friends old Lumia 920 with Windows 8/8.1 installed on it but obviously it's not really used anymore and a lot of apps are already unsupported now. So i thought i'd try and install Android over the Windows OS.
Using WPInternals i flashed the phone with a .ffu file (RM-820 - i think!) that was listed under my phones specifications, used the program to flash the phone but just before it completes i get an error message saying the boot-loader wasn't unlocked properly and now the phone won't switch on, hold a charge or do anything at all. I have tried all button combinations for a soft & hard reset but the phone doesn't respond at all. I managed to get the phone connected to my desktop temporarily in Mass-Storage mode, but then the connection disappears and i can't access it.
I've seen so many posts about this problem and being able to 'flash' it back to normal or repair the issue..
can anybody recommend or explain a technique that would work?
Many thanks!
Hi,
is there any sign of reaction in the device manager, e.g. a Qualcomm_USB device or a Qualcom_COMx port?

Good Morning Ladies and Gents;
I am working with an LG G4 H811 (T-Mobile) on 20v (MM 6.0), which I would like to root. I have unlocked the bootloader, which is confirmed every time I start the phone. I then tried to root using LGUP, but the phone wasn't recognized, so I did an error recovery reinstall in LG Bridge, thinking a fresh software install would re-align things.
Now, whenever I connect the phone to the computer, I get a pop-up window on the phone saying "USB Connection - Allow this computer to access your phone data?" CANCEL/ALLOW and the phone does not show up on the PC screen or in Device Drivers until I tap "ALLOW". Therefore, it is not recognized by any software without tapping ALLOW.
More than an inconvenience, this effectively prevents me from any mods on the phone, because I need to shut off the phone and disconnect from the USB port, then reconnect with Volume UP pressed to get to download, and in download mode I have no access to ALLOW the USB connection, so neither ADB nor FastBoot recognize any devices, and the phone is not included in Device Manager.
Of course, the bootloader is unlocked, Developer Options enabled, OEM Unlock on, USB Debugging on. I am using an original LG USB cable. I have tried 4 different computers and three different sets of drivers. I've tried older drivers on older and newer computers, and vice-versa, for every combination available. Each time, I plug in the phone after a fresh computer install and let it install it's own drivers. Two of the computers are Windows 7, two are Windows 10. I've tried connecting in MTP mode and PTP mode, with no difference. I've removed the SD card in case it was affecting things, and done a factory reset on the phone. Auto Play options have been set on the PC to "Do Nothing". I've searched the internet and this forum without results.
Basically, I've spent two days on this before asking for help. Has anyone else had this experience and solved it with something other than drivers? I think I've just about run out of ideas! Thanks.
I don't root however it's probably Developer options>usb default settings>usb tethering
Try connecting directly from Disk Management on the PC. Use the scan for new drives option if it's not visible.
Thanks buddy, appreciate you trying to help out.
Tethering is a way to allow a device connected to your phone to use the phone's data connections. In the tethering instructions:
"You may not be able to access the data files stored in the phone's memory, such as pictures, music etc, or transfer such files between your phone and your PC when USB tethering is on"
However, its worth a try - so I set up tethering, unplugged the phone and plugged it in again - the same Cancel/Allow screen came up, and no device in DM until I tapped Allow.
I then opened Disk Management and plugged in the phone. I still get the Cancel/Allow screen, and rescanning devices didn't show anything new, because the phone is not in the Device Manager until I tap Allow.
The key here is finding out why the phone or computer do not store the "Allow" command. Normally, the phone will show this screen the first time you plug it into a computer, and when you tap Allow, it will store that someplace such that the phone and computer are recognized as safe devices. You should never have to see the permission screen again. My challenge is that I don't know where that permission is stored - is it on the phone, the computer, attached to the driver? Don't know. And I don't know why it's not being saved. If I had those answers, I could probably edit the registry (or whatever) to make this a permanent attachment.
Thanks!
You're welcome.
Maybe debug mode?
Try turning off Developer options.
Obviously there is a way, sorry but I never had to use that function.
Try some Google searches which is how I usually find answers and/or by just playing with it
Well, I wouldn't be able to communicate via ADB with Developer Options off. And I spent two days searching the internet before coming here, and all I found was people updating their drivers, which is why I tried so many combinations of Windows versions and drivers versions.
I'm actually kind of surprised that this seems to be such a unique problem, I was hoping someone would notice the post who had actually had a similar problem and fixed it. But I do appreciate you trying to help!
Sorry I can't help, but I never choose to root.
It's time sucking black holes like this that I deliberately want to avoid.
At least you didn't brick it...
ha ha... you got that exactly right! Every time I do this I end up spending DAYS trying to get up to date on everything that has changed since my last phone!
Well, I appreciate you taking time to try to help.
