Need Help! Tablet Stuck and Fastboot Not Working

I am sitting dead in the water with an EVGA Tegra Note 7 that can't turn on Wireless and won't let me install drivers to move further or even do a restore.

First off I am using Tomsgt Super Tool: http://forum.xda-developers.com/showthread.php?t=2627654

So my device was continuing to fail an OTA update so I was going to use this device to reinstall the basic 4.4.2. However during the process Fastboot.exe gave a failed message in Windows, but it showed fastboot after the device name. I continued to let it Restore Tegra Note 7 to Android 4.4.2 and first of all it did it way too fast and once it was finished I couldn't get the Wireless to enable. I read another person with the same problem that had to redo the process. Well I can't get past reinstalling ADB and Fastboot, now not even ADB..

I tried uninstalling the device from Windows letting it reinstall and then checking it again. No matter what I do the USB Driver Scan fails over and over. I got this issue the first time, but somehow I got it to catch the device once and install ADB.

1) Yes USB Debugging in Enabled
2) Yes Anti-Virus is Off
3) Bootloader unlocked
4) Tried Different USB Ports

So what the hell is going on here?? All I wanted to do was run a damn OTA update.. Now I have a tablet with no wireless and I obviously can't do an OTA update now.



I was thinking about not using the tool and doing it all manually like I used to do, but all the tool does is auto execute files/folders in specific orders, basically an elaborate .bat file. So if it is failing at ADB, it is going to fail for me manually too.
Please give me some idea of what to do. I don't see how relocking the bootloader would do anything, but aside from that it was a non-rooted stock 4.4.2 OS running.

Is there something I need to do in order to get Impactor to work?

So then I plug the device into a 9 year old laptop with Windows XP and Impactor sees the device on the first try and installs the driver (it takes 2-3 minutes). Then it finishes and I close impactor, but I get an error next saying device not found. I restart the machine and now it is exactly like my desktop, Impactor can't see the device at all.

What in the hell is going on here? If I had known all this was going to happen I would have skipped their damn OTA update that continued to fail.

BTW with XP I can prevent Windows from installing any type of driver, so I did. Should I let XP search for a driver and see what happens?

Someone throw me some ideas, you can see a full explanation of what is happening if you scroll up to my screenshot. I basically have a dead device because I wanted to use this tool to do a recovery...

Wireless refuses to turn on, it just sits there for hours if I let it.


Someone please give me guidance, I was out of the Android scene for a while and I've forgotten a lot of the tricks I used to know.

If your computer is recognizing the fastboot mode that is all you need. Forget the supertool for now.

Can you use the tablet to get into the Fastboot Protocol? It so that will put it in fastboot mode even if it doesn't look like it.

If that works, you can run TWRP or a custom recovery by using ADB and the fastboot command "fastboot boot TWRP_recover.img"
Notice the fastboot "boot", that will only run TWRP once so if you want to on your tablet for good you replace boot with "flash". fastboot flash TWRP_recover.img
You have to make sure the filename is correct with the custom recovery you downloaded.

At this point, put the update you want on your SD card, put that card in the tablet, and go to TWRP or your custom recover and upload the new software.


It sounds complicated but it isn't.

Thanks for the suggestions, but I don't think Fastboot has completely installed on my tablet. When I hit Fastboot kernel all I get is a black flash and back to the bootloader again. I believe there is a quick message that flashes the first time I try to select Fastboot, however it's way too fast to read. When I do it again after that is when I will see a black flash, but apparently from what I have heard that is all Fastboot kernel is supposed to do??

How do I verify Fastboot is working before I flash the damn thing?

That is what I was saying when I said you wouldn't even know you're in fastboot. The black-screen with message flashes for a milisecond and goes back to the same screen so it looks like nothing happened when it is actually in fastboot mode. :eek:

You can verify this by running your super tool and it will say "fastboot device"

Do you know how to use the ADB command prompt?
Using that, I flashed a custom recovery and then put the below 4.3 zip file on my SD card and going through the tablet I used the TWRP custom recovery to upload 4.3 on the tablet.

I used this old backup of 4.3:
Forum post and links: forum.xda-developers.com/showthread.php?t=2580287
Backupfile name: productionbl_signed_tn7_114gp_2923379__4.3.zip



FYI,
I was in your same situation and that worked for me. I could not get my computer to recognize my device in anything other than fastboot mode.

Can I get some official links for the newest/compatible versions of TWRP and the latest stock ROM I can install that is the most up to date (with Google Apps)?

Sorry to ask, but I am short on time most of the time and I might have an hour or so to work on it tomorrow.

I have two files which I believe are correct except the TWRP file has an odd extension..

"Shaky156-TWRP-recovery.img.exe"

the other that is supposed to have GApps is: Stock-4.4.2-2.5-TegraNote7.zip

If that zip is only like 440 MB is that even possible? Can someone point me in a better direction if this sounds wrong.


Sources, TWRP: http://forum.xda-developers.com/showthread.php?t=2586432

Actually thinking about it and I bet with having things specific to img files like IMGBurn and other software it may create a .exe so it's easier to emulate it as a disk.

Do we have any good custom ROMs these days you'd suggest over stock? Are any that stable yet? If not can anyone find me a complete download if a 440MB zip is too small to have GApps in it.

I used Fastboot commands to get TWRP installed and Android is "upgrading.." now, so hopefully this will fix it.

I have the tablet up and running going into Google Play now.

I used this thread's link for the latest TWRP (2.7.1.0): http://forum.xda-developers.com/showthread.php?t=2586432

I got a completely stock version of 4.4.2 and OTA shows this as the most up to date version. I got my copy of the 4.4.2 ROM out of the Super Tool's folder that you can find here: http://forum.xda-developers.com/showthread.php?t=2627654

The tricky part to this my first time was I forgot you can open a command window inside the folder that contains TWRP/Fastboot/etc. (hold Shift and Right Click in the folder where all the data is and hit open command window)


Obviously everything came off a SD Card installed into the TN7.

answer for dummies

Hi
Is anyone able to explain how to rectify wifi being turned off constantly in basic non technical talk?
I am not a tech pro and am unsure what to do
All of the above answers are like a different language to me .

Your best bet is to find someone you know who the above is not a foreign language to. I mean it could be broken down step by step as basic as possible and you may still not understand parts.
