[Q] Receive "Unable to connect for backup" with Nexus 7 Toolkit - Nexus 7 Q&A, Help & Troubleshooting

Hey all, I am a noob to the root process but I am giving it a try on my Nexus 7. I am using the following thread on this site but since I am noob I cannot post to that thread. I did search the site but couldn't find a thread that was enough like my issue to help me.
[Google Nexus 7 TOOLKIT V2.0.0] Drivers, Backup, Unlock, Root, CWM, Flash + MUCH MORE (Thank you MSKIP for your seemingly excellent post, can't wait to finish to root and CWM process!)
I have installed the drivers, booted into fastboot mode and the toolkit sees my system but when I try to backup everything I receive the error "Unable to connect for backup". It creates a backup file on my PC, but its a 0 KB file.
Nexus 8 GB Android 4.1.1
Windows 7 64bit PC
Thank you in advance for any help. It is much appreciated.

[Q] [HELP][DRIVER ISSUES] MTP not working

Guys i think i made a mess...
Earlier when i had installed a fresh copy of windows 7, my PC showed me nexus 4 MTP under Portable Devices from where i could transfer files and all...(i didnot had the android-SDK Kit with adb at that time)
I wanted to flash stock image back so for that i downloaded the WUG's Dev KIT 1.7.3 and so when it was checking for my ADB status i didnot return that allow PC to read adb on my Phone and so the TOOLKIT gave an error...so i went for the initial setup to install drivers in which the step states to uninstall every installed driver related to my NEXUS...i did so...after wards in step 2 it asked to to install the Google/universal ADB drivers which i did and i finally restarted my pc....
Now what issue i am having is that neither my ADB is connecting nor my device is showing under portable devices...!!!
Guys please help...i am unable to fix this because i want to make a clean my internal storage but not without making a backup of Picx, Music and Downloads and esp. the Titanium and TWRP BCKP files!!!
HELP HELP HELP!!! :crying::crying::crying::crying:
And now my Lappy is not even trying to install the Nexus 4 driver, earlier it used to show not installed

What recovery are you using? Last I heard TWRP over 2.6.3.0 had issues. Try that certain version or use CWM

So can you give me a little more detail on what you did? This is my first unlock, root, custom recovery, and custom ROM ever, so if I made a mistake, I'm not sure I could even identify it. I used wugfresh's Nexus Root Toolkit to reach this point.
I have TWRP 2.6.3.1. Is the solution to flash a previous version of TWRP? If so, can you direct me to instructions for that?

Fastboot flash recovery nameofrecoveryimage.img

Complete Instructions
I'm a newbie, and this is what I did. I can't take responsibility for anything that happens to anyone's device, nor answer any questions, because I only half understand it myself. I am sorry I can't include links. I am too new, and the website won't trust me to do that. So, you will have to search for these things on your own.
Download Stuff to your PC Note: Some antivirus software may trigger false positives on these kinds of files and block them from downloading, so you may have to temporarily disable the website shielding portion of your program.
1) The fastboot.exe file. If you want a big download, you can get it in the Android SDK. However, I got it from the CyanogenMod Installer. The installer failed to work with my device, but conveniently downloaded the fastboot.exe file for me. I'm not sure I would recommend this route if you don't want CyanogenMod.
2) TWRP 2.6.3.0. You can get it from androidfilehost.
Safety Stuff
1) Compare the MD5 code on the website to the one in your downloaded TWRP image.
A Windows utility to do that is called MD5 SHA Checksum Utility.
An Android utility to do that is called MD5 Checker.
2) Completely back up your current Android ROM. Nexus Root Toolkit is great for this and many other things. It can be downloaded from wugfresh.
The Custom Recovery Flash
1) Make sure USB debugging is still enabled on your Android device. The video links on wugfresh's page can show you how to do that.
2) Make sure your Android device is connected to your PC via USB cable.
3) Boot your Android device into the bootloader. I used Nexus Root Toolkit -> Advanced Utilities Launch -> Reboot Bootloader to do this, but I think you can also do it by turning your device off, then holding down the Power and Volume Down buttons simultaneously (don't quote me on that).
2) Search for the location of fastboot.exe on your PC. Mine was in my user directory, where CyanogenMod's installer left it: C:\Users\{Username}\cminstaller\bundle\win32
3) On your PC, open a command line. Go into the directory where you found fastboot.exe above.
4) Type fastboot flash recovery {Complete directory location and file name of TWRP image}. If you would rather not be using the complete directory location, you can always copy the TWRP image into the same directory as the fastboot.exe file, before doing this step.
5) The command window should soon say "finished". Mine took under 2 seconds.
6) On your Android device, the bootloader should currently have a big green arrow that says "Start". Press the volume down button until the arrow says "Recovery". Then press the power button. Your device should now start TWRP 2.6.3.0.
Best of all, using TWRP 2.6.3.0 for custom recovery, instead of the newest version, really did solve the original problem. Yeah!
Unfortunately, the next time I used Nexus Root Toolkit, it insisted on updating back to TWRP 2.6.3.1. So, hopefully I won't have to flash another ROM in the near future and the next TWRP version will fix the problem more permanently.

Nexus not recognized by Windows in bootloader mode: how to update from 5.0.1 to 5.1?

Hi,
here is the situation with my Nexus 4:
* Android 5.0.1
* rooted
* TWRP
* can't access via adb while in bootloader (I tried everything I found over the Internet... uninstall/reinstall driver, tried another port, another computer, another OS, etc.)
* device not recognized when I use the "ADB sideload" option of TWRP (In Windows device manager I see "Nexus 4" with a yellow mark but I haven't been able to find a driver for it)
I want to upgrade to Android 5.1.1 (and won't go further), but how?? since I can't do the OTA update (because of TWRP) and I can't flash the Google official image (since I can't access while in bootloader)...
I don't care if I need to wipe everything, my backups are up-to-date (nandroid + Titanium).
Does anyone has an idea?
I can access to my device from Windows via ADB commands only (not convenient but it works).
Thanks a lot.

thanks for your help. Before I saw your post I used Skipsoft toolkit. Seemed to work but now my device won'T boot, it's stuck in the lolipop animation boot. I switched it off many times, but still stuck. Maybe I should have used wugfresh toolkit. I'll give a try later. Thanks again.

Failed install of Autodroid

Good Day Gents
Firstly, thanks for the excellent forum. I searched but did not find a solution to my problem.
I have a Nexus 7 grouper, on Android 4.4.4 I unlocked and rooted the device successfully using Wugfresh Root Kit.
Downloaded AutodroidZip files, from the two sites listed on Xda Forums, into my PC and into my device directly, I then proceeded with the Wipe Action using TWRP and installation from my internal storage, and rebooted, However it does not seem to have installed when i checked in About Tablet under settings, the stock rom and Kernel is still present.
Please give me some guidance on the installation process.
Regards
Razak

If you are experiencing what I am, this appears to be working...
In the old days, to flash a Nexus Device, wugfresh's Nexus Root Toolkit was what I used. With my current Nexus 6P, I'd recently been tinkering with a newer LineageOS unofficial ROM, and somewhere along the way, I ended up with that "Couldn't parse partition size '0x'" error, and sometimes others, when trying to flash the original ROM back, and was afraid my phone was history. However, I remembered wugfresh's Nexus Root Toolkit, and that it had options in it to "unbrick/debrick" a nexus device. So, I took my already downloaded latest official GOogle Nexus ROM, hunted down the wugfresh nexus root toolkit, and then it was readily able to restore my phone to its previously functioning state, just like in the old days. Now, at this very moment, I just did this... I don't know if anything else will pop up not right, but it didn't give any errors when it went to flash the official rom, it rebooted, and is now waiting for me to set up my nexus phone... lol... so it looks as though the crisis has been averted... Since it is no longer supported, and bitdefender throws up warnings when i try to go to their original website. I used the techspot's website to download the toolkit. And, of course, the official google android rom site for the latest official ROM.
1. Downloaded Wugfresh Nexus Root Toolkit.
2. Downloaded latest Nexus 6P (angler) official ROM.
3. Installed Wugfresh Nexus Root Toolkit.
4. Put phone in Bootloader and connected to computer.
5. Ran Wugfresh Nexus Root Toolkit
6. Manually selected Nexus 6P.
7. Selected any ROM version.
8. Under (Restore/Upgrade/Downgrade) - Flash Stock + Unroot ... I selected "Soft-Bricked/Bootloop ... and then hit "Flash Stock + Unroot"
9. Selected "Other/Browse... For use with any factory image package: zip/tgz"
10. Selected "I downloaded a factory image myself that I would like to use instead."
11. Clicked OK.
12. Selected the previously downloaded latest Nexus 6P (angler) official ROM.
13. Watched with gratitude as it seemed to resuscitate my favorite phone.
I hope this helps someone else who may have fallen into this... I'll post again if it turns out not to have solved the problem fully.
