[Q] Double Power D7016 7" - Android Q&A, Help & Troubleshooting

I just bought this tablet today, and I wish to root it to run the Android OS 4.3 or higher. It won't let me play Magic 2014 and I can't successfully download the Google Play Store. Does anyone know anything about this who can help me? Would the rooting process be similar to other Double Powers?

---

Also just picked up a few of these for the kids. Noticed that it does not have google play or log in services. will have to push the apk and libs to the tablet after root has been granted

I just got the same tablet for the kids, super cheap. I used kingo-android Root (just google "kingo android root cnet") it's super easy!:good:

Ah, damn it, I can help, but I can't post hyperlinks. I'll see what I can do. If this is hard to read, I hope some non-rookie will quote me and fix the links in the quote.
I picked one of these up on Black Friday for less than 50 bucks. Good times. It was a bear getting the Play Store not to crash every session. For quite a while I struggled with the Play Store seeming to run OK for a minute, then "Unfortunately Play Store has stopped" and back to the home screen. Clearing the cache and making sure the Download service was started didn't help. But now things are looking up.
I'm still running Android 4.2.2, which is what the tablet came with. I'm afraid I can't help you with finding a 4.3 rom.
Anyway, mgordon's suggestion of Kingo Root works as well as any. You can also use its bundled adb.exe to push the Play Store onto your tablet. To install a working Play Store, after rooting, follow these steps:
Get this Play Store APK: triple-w dot androidfilehost dot com /?fid=23203820527945029 (found [here](triple-w dot androidpolice dot com /2013/11/01/download-latest-google-play-store-4-4-22/#download))
Go to your Start Menu --> All Programs --> Accessories, and right-click on Command Prompt and choose "Run as Administrator."
In the command prompt window, navigate to adb supplied by Kingo Root. (cd "\Program Files (x86)\Kingo Android ROOT\tools") then continue with the following additional commands.
adb push \users\yourusername\Downloads\com.android.vending-4.4.22.apk /system/app/com.android.vending-4.4.22.apk
adb shell chmod 755 /system/app/com.android.vending-4.4.22.apk
adb reboot
Good luck!

I attempted three or four various methods of rooting before successfully rooting with Kingo. It could've been that Kingo wouldn't have been successful for me without the filesystem modifications made by other tools -- I'm not sure, and don't really feel like restoring to find out.
Maybe try rooting with sf.net/projects/rootandroid ; and after reboot if your apps fail to gain root privileges, use Kingo to remove and restore root. See if that helps.

I will give that a try. Thanks!

Here's another useful hack. You know /sdcard points to the rather scant internal sdcard. Once you install a few apps there's little room left for music, movies, etc. You can put some of your media on an external sdcard mounted at /mnt/extsd, but some apps expect their media content to be accessible within /sdcard -- camera apps and FireTaps, for example.
It'd be nice if you could have /sdcard/DCIM and /sdcard/FireTaps as symlinks from true directories on /mnt/extsd. Unfortunately since sdcards use a fat32 filesystem, symlinks aren't supported. You can, however, use mount bindings to accomplish the same sort of thing. Mount is a kernel thing rather than a filesystem thing.
After you get your tablet rooted, you can install and use "Universal init.d" from the Play Store to execute user-made startup scripts. I wrote the following script to bind all the directories from my external sd to my internal. I saved it as /system/etc/init.d/99extbind (using ES File Explorer with root permission) and did chmod 700 (from a JS Terminal console and su for root). Any directory I want to move from the internal sd to the external, now i just move it via cut & paste then reboot. After reboot, the contents of the directory are accessible from both directory trees, but physically only use space on the external card.
Code:
#!/system/bin/sh
bind_to_sdcard() {
d=$*
d2=/mnt/sdcard/${d##*/}
[ ! -d "$d2" ] && mkdir "$d2"
mount -o bind "$d" "$d2"
}
# purging empty directories
for d in /mnt/sdcard/.*; do [ -d "$d" ] && rmdir "$d" 2>/dev/null; done
for d in /mnt/sdcard/*; do [ -d "$d" ] && rmdir "$d" 2>/dev/null; done
# binding directories from external sd on internal sd
for d in /mnt/extsd/.*; do [ -d "$d" ] && bind_to_sdcard $d; done
for d in /mnt/extsd/*; do [ -d "$d" ] && bind_to_sdcard $d; done
exit 0
Edit: If you attach your tablet to a PC via USB and enable USB storage, the tablet will not be able to make the internal sdcard available to the PC. I'm guessing this is because when the tablet attempts to umount /mnt/sdcard the device is busy with other child mounts and can't be umounted. The internal sdcard is still accessible to ES File Explorer and similar while not plugged into a PC, though. I recommend copious backups just in case calamity strikes, in any case.
Edit 2: After ejecting from the PC, SwiftKey complained about not being able to read the sdcard, and predictions and swiping were unavailable. A reboot fixed it.
So far for me, the benefits outweigh the problems. I've now got over a gig of FireTaps songs, 250 megs of books, and 500+ megs of application data available in /sdcard where before i was limited to about 1.3 gigs.

More help with Google Play please...
Hello everyone I have the DOPO D7020 and am trying to install Google Play per the instructions given. I installed Kingo Root and have successfully rooted the device. I downloaded the play store APK to my desktop. I am running the command prompt as administrator but this is where I get stuck. When I follow the directions and enter the commands or even copy and paste the commands to the command prompt it says "....is not recognized as an internal or external command, operable function or batch file." Any help is greatly appreciated, thanks in advance!

You need to hold down shift and right click on the adb folder, you can't just run the adb commands from any old command prompt, not without setting environment variables, Windows gets cranky about that stuff.
EDIT: Shift, right click, and select "Open Command Window here"

So I scored a couple of these from amazon, planned on giving one to my mother for Christmas, but before that, I had to have one for myself to see what it was about. I actually used Vroot as my root solution. I was able to use the method above to get google play working, so big win there, now if I could only get TiBu to write to the external SD

Super Backup (com.idea.backup.smscontacts) will let you specify the backup path. Or you could use my mount -o bind trick in comment #8.

I actually figured it out late last night. I had the SD card formatted in Fat32, things like ES File Manager and Root Explorer could read and write to it just fine, I formatted the card with exFat and TiBu had no problem writing to it.

Where did you get the USB Drivers? In my device manager, I get "Other Devices -> Android" with a yellow triangle and exclamation point.
EDIT: Nevermind, just finished rooting! Had it connected as MTP, switched to USB large storage.
