[Q] Tablet Ematic 7 - Android Q&A, Help & Troubleshooting

Hello, i just inherit my moms Android 4.1.1 Tablet Ematic 7" EM63 purchased from walmart, a 70 dlls tablet. but with an issue, The tablet shows 0.00 HDD space available if no external SD card is plugged in, and its unable to download data or install APKs, The tablet works fine for browsing or playing files from sd card. but if the user restart the device it shows the factory reset screen after boot. The user needs to set up the wifi, google account, etc. Everytime a soft reset is done.
i've been told that not unusual activity was performed (no rooting, installing apks or messing up with files) before the issue happen. The tablet does not have Root privilege installed yet.
after a pair of hours doing research on internet i saw that it was a common (?) issue on generic brand tablets with 4.1.1 and the "busybox" application update (as im aware, no one updated the application on my moms EM63 tablet). According to "Dejan" from another forum this is the obvious fix for my issue.
Iregistered since i needed to thank you for your help, also i have some tips to add!
I had the same problem with all files wiped out and not enough space to instal new apps..
here is how i solved it.
1. Download root explorer here
2. Copy it to your memory card, and instal it (don't worry you will not have memory instal problem while installing it)
3. Run root explorer, and go to preferences and thick option "show hidden files"
4. Go back and inside root explorer there is an option "search", click on it and type in word "busybox", hit enter, after few seconds while he locate busybox location (mine was in /system/Xbin/busybox ) just copy it to /system/bin.
after that just reboot tablet..TAAADAAAM all your apps and everything is back to normal.
hope this helps and thank you again.

After trying to fix the tablet by my own following this instructions i noticed that the tablet has indeed the buxybox file in the path /system/Xbin/busybox instead the path /system/bin.
Now, here goes the question:
As stated before, i dont have Root Permisions so i cannot move the busybox to the correct path in order to complete that fix, Is it possible to fix this issue without having to root my device? Im not exactly sure how and if its possible to root my "new" EM63 tablet since there is no Hard drive disk space available.
Is there a "easier" way to fix this issue?
Thanks in advance for any help regarding this issue

as a side note, the HDD can be "read" by the pc.

I can not vouch for other methods but I have rooted this tablet with SuperOneClick ver. 2.1.1. If you leave "Exploit" on "auto" and click "root" you will be pleasantly surprised. Took me two tries, but if you turn on usb debugging in settings and leave the screen timeout on 30min your golden. Happy rooting.... I'm also uploading a google apps zip file. I unzipped it and installed all the files in the corresponding places to get a working Android Market. I used Android Commander to move the files & install apk's. *NOTE* You need to install the apps in the "/sysem/app" folder in this order...
1. GoogleServicesFramework.apk
2. OneTimeInitializer.apk
3. SetupWizard.apk
4. Talk.apk
5. Vending.apk
6. Gmail.apk
7. Maps.apk
After... Restart, Connect to wifi, and launch Market. You will be prompted to sign in to google. Then you will see Market License blah blah blah...
*Use the attached zip not the one at the following link* But use this link as a guide if you need it... http://forum.xda-developers.com/showthread.php?t=827209
Have fun.

****THIS METHOD WORKED FOR MY IMPRESSION 10 MODEL # i10-50, but UNTESTED by me on other models****
***EDIT*** Sorry guys... you were unlucky because I forgot something crucial.... THE DARN ADB DRIVER.... You will need to go into the device manager and right click the "Android" device with exclamation mark & click update driver. Search for the driver and point the installer to this folder should work on 32 & 64 bit if my edits are correct... Tested on 64 bit Windows 7.

Also when you install those "/system/app" files above use Android Commanders "Installer" and install them one at a time in the order above. AND AFTER YOU RESTART USE LAUNCHER AND NOT SETUP OR YOU CAN'T ACTIVATE YOUR WIFI.
I tried both methods,
SuperOneClick and Gingerbreak both did not work.
The table is running android 2.3.1.

Do you have usb debugging turned on, and did you use the latest version of SuperOneClick. For me it stalled when my screen timeout was to short and locked me out of my tablet when the screen cut off. Second time around it looked like it was going to fail, stalled and then prompted me to ok the install of busybox... etc etc. I am also running android 2.3.1 and it worked for me. Just have to keep trying till you get it.

Remember i'm running a i10-50, but the pictures speak for themselves. SU, Market...
Fails
I've also tried this on my husband's Impression 10 - same model i10-50. Can you give some details of how you rooted? What programs did you use besides Android Commander and SuperOneClick 2.2.1? Any help would be appreciated.
i just got an impression 10 as well. i10-50 model with android 2.3.1. im interested in more in depth info on rooting it as well. i tried updating firmware from the page it gives from the box. instructions to download the system.img file from the impression site. but i am not sure how long it takes? when i loaded the file on sd card and restarted (power+vol-) one time it stayed on the blue screen with the white status bar for like over a half hour. i thought it froze and restarted. when i tried it another few times the blue screen disapeared and i got a screen full of multi colored lines all down it. when i reseted.you could still faintly see those lines even when its running normaly. its faintly in background and you can see it more on certain pages or folders u open. my first tablet and i wish there was more info on it. any clue what im doing wrong?
dude i do customer suport forthis tablet, as u may know by now............it sux
leader Impression I10-50 firmware update
In order for the firmware update to be completed successfully, u need to first format your sd card via sd card reader or your tablet as follows:
Plug in the tablet via usb to your PC or load your card reader with sd card
Then select and left click whatever removable disk drive your tablet shows up
Select format and make sure the file system is set at FAT32
Select start, your sd card should begin formating.
Once complete, then u follow the 13 steps, but since you have already started step 1-13, just press your -volume and power buttons at the same time (steps 11 and 12 again) and it should update your tab. Be sure to do it twice as far as the volume and power button go so the update completes successfully.
I cannot seem to get this thing to root....tried the above with the external sd unmounted and then removed. Followed the instruction on the gtab post. All I can see is the external sd card. It did install superuser. Without the sd it gets stuck at Step 6.
It took awhile....but switched to EZ File Explorer. And I was able to see the internal sd and copy the files Then was able to install the market! Life is good!

Do you know if the root is reversible in case you need to put it back to the factory default? Would installing the image file on the Impression website reset the tablet back to stock firmware?

Thanks for the reply. About that file program you used, the only one I can find with a similar name is "ES File explorer". Is that the one you used?
I can't get it to copy the files over in the system directory, it acts like its write protected and fails the copy. I must be doing something wrong.
Oops yes ES File Explorer...
Need go to settings.... Open menu, choose Settings Check Root explorer and mount file system...
I'll probably just give up on this. This still isn't wanting to write/copy the files. This is the whole reason I returned my Nook Color before because of the hassle it takes to do this.
edit: it copies a few files, but then some files it says it failed.. like the "maps.apk" file.
Had a few apk's not move as well. I think map was one of them. Just followed the install order and did those from the external sd.....all worked out.

Thank you for your help. I finally got it working, I spent hours on this.
But I decided to try that original posts recommendation of using the program "Android Commander". I had to search to find it, but its a Windows program that makes it much easier to copy files over to the root directory. (although I had to change a setting it in so that it auto closes the log window after it copies, otherwise you can't close the log window, or do anything else until its closed).
I wasn't able to copy the maps with that either though, it gave the error that there wasn't enough space. But it seems to be working fine now.
Impression i10-50
I bought the i10-50 and actually love the tablet. With google market installed (update firmware first), I have full access to the market and no problems installing apps. The only con about the tab is no gps. To install the market, I only downloaded the google apps file and installed the apks in the correct order and that was it. No need to root. I am truly enjoying this tab now.

Huawei Mediapad / T-Mobile Springboard Discussion

It looks like we have to move our discussion here, so I went ahead and started a thread.
As of now, there is root for the mediapad, but the only way to root the springboard is by flashing it with a rooted mediapad cust.img - which gives you root but loses your 4g.
So for us Springboard users, we either need root or a way to get 4g back if flashing it as a mediapad. Anybody with thoughts or leads or any know-how?
Finally,
Special room for Huawei Media Pad created,
Thanks to TS
I'm very glad,
Now i'm waiting the master in here to modified this device
cause i still newbie
Actually I Prefer The 3G More THan The 4G For Some Reason I Felt 4G Wasnt Stable Enough....So Im Enjoiying My Mediapad In 3G More Than My Springboard In 4G......

Yap, only thing you have to do is install Superuser and Busybox from Market and copy "su" from /hwcust/oversea_hk/preload/fixed/bin/ to /system/xbin (e.g. with ES File Explorer with root and r/w enabled), and you are ready to go
I've installed SU & BusyBox. I cannot move the SU file over to /system/xbin. A message tells me that I am not root.
However, when I run Root Check Basic I am told I have root.
I ran Root Check before & after I installed S7-301u V100R001C232B012(Root_version) and Root Check said I did not have root.
So the real question is, How do I really know if I have root?
*****
Actually I installed BusyBox Installer. I'm asked to pick a version to install:
1.19.3
1.19.2
1.18.5
1.18.4
1.17.1
None of these will install.
I also have the option to install a "Custom Tune" is there one? I'd gladly pay for BusyBox pro to get BusyBox running
*******
I powered off the device. Put my sdCard back in (the rooted firmware was removed from it). Then installed the SuperUser update from the market.
Ran that - it said everything was OK. Then I forced it to update - it crashed - so I force closed it. I then realized I could not run the original SuperUser app anymore.
Next, I opened up Root Explorer and was able to move the su file over to the xbin. But now BusyBox is not acting right - It said that it was having problems installing, and I'd need to reflash (or reload - I can't recall) the rom.
I'm rebooting, and going to try to install BusyBox....to be clear on which BusyBox..it's this one:
https://market.android.com/details?...t=W251bGwsMSwyLDEsInN0ZXJpY3Nvbi5idXN5Ym94Il0.

Just realized in Root Explorer, to tap the little gray box at the top. After you tap it it should read "Mount R/O"
Now you can long press a folder/file and change the read/write permission.
Rumbi,
You said to r/w enabled the su file....is that check ALL the boxes?...Read, Write, Execute Special?????
IIRC, i had some problems with busybox, too. Copy the file from the attachment to /system/xbin and try the installer again.
And i said to enable r/w support for the /system folder. There are two checkboxes in ES File Explorer. First checkbox is enable root permission for ES File Explorer and second checkbox is "Mount / and /system writable".
Now you should be able to copy whatever file you want to /system/xbin. That's how i have done it. If you have any further questions, feel free to ask. I'll try to explain.
PS. You don't ne to alter file permissions of the su-binary but mine are "rwx r-x r-x".
Rumbi, how do you feel about the High resloution mode, does it slow the tablet down? Have you had a chance to use any tegra 2 devices and if so how does the mediapad with the snapdragon compare when in standerd/high-res mode?
Nothing to complain about the Hi-Res-Mode but i don't have any Tegra2-Devices to compare, sorry.
Haven't tried any games in hi-res-mode but normal usage is just fine.
Thanks. Ill try this out. When i try to install busybox it hangs first, then i force close and run again. Then i get the message about reflashing Rom. But i know i have root. I installed connectbot and ran su and got #
Heres how i got root (im away from my pc right now so i try to be as accurate as possible) :
Installed Hauwei modified rom (its the one that says "(root) " in the file name.
Installed Root explorer
Installed Superuser
Install busybox
Install Connectbot
Put my microsd back in (with the firmware AKA dloa folder removed)
I could not get root explorer to allow rw permissions until i slid the sd card out and back in whil the device was on.
Then i ran connectbot as local and typed su hit enter then superuser popped up asking fo allow connectbot to access. Hit allow an type su hit enter an you should get # This took 3 reinstalls of the firmware to work wjthout errors. The first times resulted in superuser needing to be force closed.
I also ran superuser and went into settings and updated it eventhouh its not neede. There i got a read out saying that busybox is not installed, but it does say i have root.

Honestly i havent noticed a big difference between high resolution an standard.
The only issue with high res is the small icons and buttons are difficult to hit sometimes

Do i need to unzip this file first?....
.... Nevermind... I unzipped it and put the busybox file in th system/xbin folder.
I installed busybox installer by JRummy16. This time and it worked!!!!!!!
Now its on to figuring out 4G and tryiying to use it as a phone.
What is the xml file i need to edit?
Sent from my HUAWEI MediaPad using xda premium
Good, that you have worked it out now What exactly do you want to do? To get to the hidden menu, you have to open the calculator and type: ()()2846579()()=
To edit the XML-Files, you have to extract the cust.img... But now that you have root, yo can edit whatever is available via root explorer
€dit: To get 4G working again, maybe with someone with an original Springboard (not a flashed one) can copy the folder /system/lib/. This should be possible even without root. I think it has something to do with the ril-files...
after updating my mediapad to S301uV100R001C232B012, i have problem with 2x Client (RDP client) now, few second after conecting to rdp session, is app 2X client crashing, with error 2x Client has stopped unexpectedly (process com.tux.client), is here anybody with this problem? thanks...

Even though I have no clue of what to do with this, THANKS! I tried to open an .so file in notepad, but no luck, but I'm assuming that the geniuses here know what to do.
On an off-root topic - How do you take a screen cap? I accidentally did it yesterday while my MediaPad was lagging, but don't know how I did it.
The Hi Suite that comes with the device can do this, but require a computer and usb hooked up. Useful, but not as practical as doing it from the tablet itself.
The *.so files are a bit like drivers for the internal components. I'll try to find differences between T-Mobile and Huawei so maybe we get 4G working again.

I'm not sure how to screencap. It's so easy on CM that I've gotten lazy. Plus I rarely do it. I know there are a ton of apps for that, tho. But you could probably google "gingerbread screen capture" and find a better answer. But not with gingerbread. I'm blanking on the name for this version of android.

Honeycomb
I've been Googling searches like that, and end up with actual screen shots of Honeycomb os..I'll keep looking...
Tried this (from here), but no luck:
Screen capture
Android natively supports the ability to capture a screenshot by method of pressing both the power and volume-down buttons at the same time on an Android device. This native support was first included within the Android 4.0 (Ice Cream Sandwich) update, which is first seen on the Galaxy Nexus smartphone.[86] Previously, Android did not feature native support for screen capturing which would have likely been due to security concerns. Furthermore, prior manufacturer and third-party customizations as well as using a PC connection (DDMS developer's tool) were the only known methods of capturing a screenshot on Android.
I've looked through the *.so files and many of them are exactly the same, but some are different. One file caught my interest. I've attached it here for anyone who wants to try. Please only use it, if you have a T-Mobile Springboard with flashed root Firmware. Copy the content of the zip-file to /system/lib and overwrite the existing file. But make a backup first! After copying you have to set the correct file permission (rw- r-- r--) and reboot the tab. Hopefully 4G works again with this little trick.

[Q] Azpen A701 Tablet

Does anyone have any information on rooting the AZPEN A701 Tablet (ICS OS)?
All my searches keep popping up for the Acer Iconia A701.
drivers
I found the correct address for the drivers for this tablet, and 2 others from Azpen.
www.mediafire.com/azpensupport
The links on their webpage incorrectly spell mediafire and also include .com in the last part of the link.
Note: I recently got an email from Azpen telling me the exact same url that I had already figured out. Their email is about week to a week and a half after I sent them a request for the proper address. Also, as of the time I am posting this update, they have not corrected the address on their website.
Tried methods
I have tried SuperOneClick which reports that the system is rooted, but ADB Wireless says it is not.
I have tried Bin4ry's Root Many Android! (options 1, 3, and G) and briefly got temp root on option 3 but I lose wireless functionality (I get one or the other message from ADB Wireless (no root or no wireless), verified that Wireless connection has been turned off and won't turn back on until reboot which loses me the root again).
Retries
Ok, finally rooted the Azpen A701.
What I did:
First, I went back to SuperOneClick, and choose Unroot to reverse anything it did.
Retried Bin4ry's Root Many Android! v31, option 1 (new standard method), test, failed, unroot, 3 (old method), test, failed, unroot, then G (Google Glass method), test, WORKED this time.
Verified by using a root browser (can see files/folders(subdirectories) in /data after giving permission), a root checker (note: do not turn on SuperUser's Autoanswer, gives false information from some checkers), and ADB Wireless works while in range of a wireless router/source.
I am guessing that somehow the leftovers from SuperOneClick were affecting my results with Bin4ry's collected scripts.
Props to all that developed each of those programs and scripts.
I don't know if anyone will be seeing this but I hope it helps anyone needing the info.
Just curious to know if there is a rom available in case this method bricks the tablet? I bought this tablet a couple of weeks ago because I wanted to mess with one and I didn't have a lot of cash to spend. I use it daily and my kids play games on it. I can't afford to get another anytime soon, however I'd like to have it rooted so that I can remove factory installed apps that I don't want or need.
no idea

I have absolutely no idea. The only additional rom I have seen ANYWHERE is the Jellybean update for it (see driver link above). This seems to not be a very popular tablet to work with, going by the fact I received no help from anyone here. All research on this so far has been done by me. I stumbled on to Bin4ry's rooting method by accident. I'm not a ROMer, I don't know how to build one. Also I don't know which ROM backup method to use on it/will work with it.
Alright
I'll give it a shot during the weekend, I've grabbed the jelly bean update (thanks for the link). Hopefully all goes well. I figured there would be little to no support for this device, however due to a tight budget I chose to get this tablet.
I don't really mind the lack of support, however I'd like to have root because like on my old phone I had a few programs I used that required root.
Thanks again.
*Edit*
I attempted last night as I had free time to do the root method and unfortunately it did not work on my device. Not sure why it did not work. I'll try it again at a later time when I can. I also attempted to upgrade to 4.2 but it seems as though I am having issues with it as well.
Maybe I'm just stuck with the tablet as is

It may have been the sequence I used. Tried SuperOneClick several times (as above it said tablet was rooted but several apps said it wasn't) which installed su, busybox, and superuser. Then found Bin4ry's method, got temp root (tryied 1, 3, and Glass). Then went back to SuperOneClick and unrooted, returned to Bin4ry's and finally got it with Glass method.
Don't know if that helps
Well
After several attempts via Bin4ry and SuperOneClick I have obtained root on this tablet.
Not quite sure which actually did it though as with super one click it froze on me during both times I used it and each time I tried Bin4ry's method I kept getting messages about connecting my device (which was connected fro the get go).
After several tries with these programs yesterday and finally saying screw it I decided to add some apps that required root. I don't know why I did it I just figured it was worth a shot. I added Super User which told me I was rooted, then I added Titanium Backup and was able to use it as it is intended. For added measure I also installed and ran root checker which as well as super user verified that the tablet had been rooted.
Good to see that your were able to root.

So I think we can safely say that using both methods together + patience will root this tablet (don't know why one or the other wouldn't do it).

I have been trying to root AZPEN A701 for the past week, I have tried everything written on this forum. Any help PLEASE!
clean slate
Are you willing to do a full restart on the tablet (factory reset)? I had to do that before my root took, as I found on other systems that I have rooted some programs you load can interfer with rooting. Save any personal data before you do this, programs can be reinstalled from Google Play or (hopefully you saved them if you downloaded them) your computer
Factory reset:
Press and hold up volume button then press and hold power button. The screen will remain black (no backlight)
Wait 4 seconds then release both buttons (backlight will come on). Shortly the android on it's back with the open torso (the sick android) will be displayed.
Press the down volume button. You should see 5 options available- You are now in the System Recovery program.
Using the up or down volume button to highlight an option then press power to select the option.
1) select Wipe Cache Partition
let the unit reboot, then turn it completely off
reenter System Recovery again.
2) select Wipe data/factory reset
let the unit reboot, then turn it completely off
The system is as clean as it is going to get now.
On your pc (don't know for MAC's) download the drivers, Android programs needed (Android Debug Bridge -ADB- is part of the Android Development kit and some Java Development Kits), and both SuperOneClick and Bin4ry's root software. Install all software and drivers as per their instructions. Run SuperOneClick and Bin4ry's root programs. Busybox and SuperUser will be added automatically by these root programs.
While having wifi and internet access (McDonalds anyone?), re-sign up for Google Play (sorry, but the settings got wiped earler). Go to Google Play and let all the programs update. Update Busybox and SuperUser if needed/possible.
Download any root enabled file system browser (FSB) (permission will have to be granted in program to use root functions) - I used Ghost Commander for mine. It may take a bit to find it in the directory structure for the FSB you downloaded but you need to get to the root system folder.
Ghost Commander has a Local Storage option press it and an new list of folders/files will be displayed, move to the previous folder level (double dots at the top) and give permission to move to a system folder, move to the previous folder again to get to root directory, "/mnt" is the directory you just came out of and is highlighted but you will be at the root of the file system.
Enter the "/data" directory. If you can see files listed there, you have root; if not rooting attempt failed.
Once rooted, doing a system cleaning and Factory reset will not remove root but will remove SuperUser and Busybox (re-run one of the root programs to re-install then update the next time you are on the internet/web). Updating/upgrading the rom will remove root if the rom does not have root activated - I don't know of any custom roms for this tablet (there is a Jellybean upgrade in the Azpen website, if they haven't updated to the correct web address then use the one I listed on the front page, mediafire is spelled wrong in the address). Nandroid level system backup is not available yet for this tablet to my knowledge.
For several reasons, do not turn on SuperUser's automatically give permission option (the one that affects all programs), except on a one for one basis: 1) some root testing programs will fail if this option is turned on, 2) security: turning this on will allow ALL programs - including some malicious ones - to have super-user rights, 3) you will get to know which programs are asking for root permissions beforehand not after, you may want some to have automatic access (like DroidWall in my case, a firewall) and not others.
Also other information that can be useful:
/sdcard does not refer to the removeable SDCard but to the internal user data area. All programs that can be moved to a SDCard (like by Apps2SD) will be moved to this directory by default (some may allow re-assignment of the destination location) instead of the removeable SDCard (blame Azpen, it was their decision to use the directory and name that way). On most other systems /sdcard is the removeable SDCard.
/extsd is the removeable SDCard, when installed, maximum size is 32Gb.
/usbhost1 is for any usb flashdrive connected by a USB-OTG cable (OTG means On-The-Go, special usb cable that puts the tablet into host mode, similar to connecting a flashdrive to a computer, the cable is not a standard Data Connect/transfer cable, one USB-OTG comes with this tablet). Note about USB-OTG cables: if one is connected you can connect either a flashdrive, usb keyboard, usb mouse, combo keyboard/mouse unit, or a powered usb 2.0 hub. Only one flashdrive can be connected at a time (anyone know of downloadable software that would allow 2 or more? I know some modified kernels can allow more than one) so with a hub you can connect a flashdrive + keyboard + mouse (I use the RII wireless combo keyboard and mouse with mine). Maximum size appears to be 8GB, format must be FAT32; will be testing with a 16GB key shortly.
Azpen A701 and Jelly Bean
Shortly after I wrote the above I had to re-flash my tablet, but Azpen had deleted the ICS image (after a request it was restored to the site, get it while you can) and had to flash Jelly Bean. I found there were troubles with this image.
First: I could not write to either the external SDCard (called extsd) nor an attached USB flash key; reading was unaffected. I found this out when I attempted to reassign my backup location to the external sdcard and it was unable to create the directories.
Second: I couldn't find a rooting program.
After a little research, I found that the external media had not been given R/W permission in the platform.xml file - I could actually navigate the FS and read the file even without root.
Also I finally found after 2 days of searching a root program, VROOT, http://forum.xda-developers.com/showthread.php?t=2434453, that would work. Be prepared to deal with Chinese for a little bit and follow the instructions on that page (press the buttons to see screenshots). The superuser app needed to fix/replace the Chinese app is SuperSU (Google Play) which supposedly fixes problems found with other superuser apps. Once you have downloaded SuperSU, had it download/update its binaries and have rebooted, you will have to disable the Chinese Superuser app as you are unable to uninstall it using the app manager: I located it by its icon (shield with cog) in /system/app and appened '.old' to the name: "Superuser.apk" => "Superuser.apk.old'. I didn't use Titanium Backup as suggested because I am not a fan of the program .
platform.xml is located in /system/ext/permissions. After you have root, open platform.xml in what ever text processor you want locally or transfer it to your computer and work with it. You will have to add '<group gid="media_rw">' to the 'WRITE_EXTERNAL_STORAGE' group, on the line after '<group gid="sdcard_rw">' (don't type the single quotes but the double quotes are needed) and write the file back to its location (need root for that, adb pull/push may be possible to fix this). Remember on this tablet, sdcard refers to the internal user storage, media_rw will give permissions to the extsd (external sdcard) and USBHost1 (using included USB-OTG cable and a flash drive). I rebooted the tablet and tested the RW state of extsd, and voila, it now is write capable.
I wish there was more aid on this tablet but since it is not mainstream (not made by a big manufacturer like LG, Motorola, Samsung, etc.) I doubt that it is coming (I am not a ROMmer but have been using computers since the 80's, so I know a few tricks and am always learning). I will keep adding info as I find or fix it.
I will probably go back to ICS as some of my programs are not working right, and JB is sluggish.
I just picked up the A700 from Microcenter, and this is the ONLY reference to rooting the device I could find. The Azpen website doesn't even acknowledge the device's existence. I just came across this yesterday: Azpen A700 - Cyanogenmod forums. I used the Kingo method without a hitch.
Hopefully, all the other folks who get that tablet for the pre-Black Friday sale who found this link will benefit.

I picked up this tablet also. Not bad for $40. I used this method to root http://www.cydiaimpactor.com/ It worked the first time. I just had to do it on an old XP machine. Windows 8 would not load the right android drivers. Now I'm working on getting Titanium backup to see my external SD card.

Glad it worked for you! I started this thread for the A700 http://forum.xda-developers.com/showthread.php?t=2532464 - No activity in it yet. But if you come across anything good post it over there.

Update
I am glad to see that others are taking an interest in this tablet.
I found 2 methods that worked and am glad that others are finding more.
Now if I can get the boot loader cracked I could finally make a nandroid copy and save myself 4+ hours restoring everything when it goes wonky. This has happened twice- OS partition fills up (and don't know why) and the device resets to near factory reset level (even some of the factory apps are missing) and won't install anything but the smallest of apps which are deleted on the next reboot; the only solution is to re-flash the tablet. Note that I have gone back to using ICS as JB has other problems (external media including its own sdcard partition is not rw enabled for one).

How to fix the "invalid download uri" problem

Hi
"Invalid download uri" is a bad ass error that is the biggest flaw (IMHO) You can encounter. Solutions are (as far as I can tell):
- cache clear
- factory reset
But for those, who did this and still have the same problem (or don't wanna try the factory reset) there might be some hope. (I was searching for solutions and found none like this, so I hope I don't duplicate someone's ideas)
I was fighting with this for a longer time and I guess I finally managed to fix it. I tried to clear cache, Google Store and Services, I even removed and reinstalled Google Play. But as logcat said, there was still problem with access to the file that was downloaded (something about JaveException:FileAccessInvalid - or something similar).
So, to make the long story short:
- connect phone
- adb shell
- cd /data/data/com.android.providers.downloads
- ls -al
There should be 4 directories:
- one of them (install) is a link (not visible in CM File Manager, but visible in shell)
- app_sslcache, cache, databases
Those three should have similar attributes (drwxrwx--x), in my case, cache had ony drwx--x--x.
So an easy fix: chmod 771 cache (You should be root) and voila, everything works (You don't need reboot or to stop google play or anything) and no more "invalid download uri".
Please, if You have this problem try this fix and if it works for You, let others know (maybe even in the comment section below)...
PS: It's not dangerous, but anyway... You do this at Your own risk.
It WORKED!
What a life saver, I was able to change the permissions through FX Root Explorer.
Thank YOU.
Thanks!!!
Old thread but throwing a thank you out there. Was having this issue after rooting my VZW M8 and this solved the problem. Thanks! I also shared this link over on AndroidForums.com as I found a similar thread with no solution while googling this issue.
So thanks!
Thank you, for the inspiration, by looking at the logs, it was some permission pbl in com.android.vending and after some try, it was com.android.vending itself that was with bad permission.
771 on com.android.vending fix it for me!
Hi, was reading your suggestion how to fix problem"invalid dowload url' problem, followed your guide but no luck.
You wrote:

- one of them (install) is a link (not visible in CM File Manager, but visible in shell)
- app_sslcache, cache, databases
I have galaxy S5, rooted, using root explorer(everything visible) and within data/data/androidproviders.downloads I have only 3 files.
cache,databeses and lib.
but in another directory data/data/com.android.vending I do have files you mentioned and some more.
All of my files as well directories have same set of permissions, which is
rwxrwx-x
I know you mentioned we should have drwxrwx--x and I don't know how to change it(if my permissions are wrong).
IF you can help pls I would appreciate.

Must be the "new" Android version... I don't have enough info to help You. the pesmissions are correct. That "d" in the beginning says it's a directory. After that there are rwx (means: Read, Write, eXecute) three times. These permissions are for Owner, Group and Others. That means the owner (the app that created this directory/file) should have full rights:rwx. He can read, write and execute the file/directory. Group is just a group of owners that can share some data. Like, You can put pictures into a directory and have all apps in group "viewers" access them. And then Others. Others are all other apps that are there. So basically drwxrwxrwx means anyone can do anything with that file/directory. drwx------ means only the owner has full access, all others cannot do anything. That's the permission system in linux/android in a really really fast lesson.
Now what You need to do is to find where S5 puts the things it downloads from App Store. Maybe You are missing that folder I have found. Dunno. Try to google it out and maybe someone can help You better. Or try to find it Yourself.
What I would do is to connect S5 with a cable to a PC, run adb shell logcat and then I would try to install something from the App Store. You will see all that crap that's going on and if there will be an error, You can see it, read it, think about it and solve it
Ot put it here and I will think for You
"invalid dowload url' problem
Thank you very much for super fast response. BTW, besides this post about 'invalid dowload url' problem there is nothing on the net, not one single word. I resolved my issue with reseting my phone and everything is fine now(it was easy since I have back up of everything). Will re search more and let you know if find any answers. Anyway, was looking at permissions in same folder after reseting my phone and everything is same as before but works. Thank you again, for your effort.

Try without an SD card in your device.
I don't have install in either place (com.android.provides.downloads or com.android.vending) on my PadFone X and keep running into this issue
EDIT: In my case it won't download the whole app.
EDIT: Downgrading Play Store fixed it!
Thanks, it worked
I didn't try changing permissions but just cleared the Download Manager data and it did work
Did this with Root Explorer, just want to mention, permission 771 should be granted not only for cache folder, but to every sub-folder.
Anyway thanx, this is really working solution.
Just a quick note: Noticed this error after installing the Xposed Module "Root Cloak". Since this error only showed up for root apps I figured that was the problem. Was able to update (TiBU and Greenify) by disabling Root Cloak - rebooting - updating - re-enabling Root Cloak.
Not sure what item I added to Root Cloak that is causing this issue, but for now this "solved" the problem for me.

Dead or not I have ran into the exact same thing twice. First time was right after root cloak, and this time its been a while. That and a bad memory had me end up here. Root Cloak or not a simple fix permissions in something as old as ROM Manager or just do it in custom recovery fixed it for me. Android 4.3. Galaxy Note 10.1 2014 rooted stock with multi user. I note multi user because it has also caused me some grief due to knox magically appearing in the second user even though completely removed from ROM and also must enable multi user root in supersu. Thanks for making me chase permissions instead of go after the old sd card mount issues.
Fixing permissions worked for me thanks!
Solution to "Invalid download URI."
After some time of troubleshooting this issue, and performing all the previously recommended steps, we believe we found a really easy solution. In fact, I feel really frustrated that I didn't do this to begin with, but hey, live and learn.
This solution will typically work for folks who are getting this on almost every app, with a few exceptions. You may notice that some apps will install while others throw this "Invalid download URI." When an app is downloaded, the installer will then look to see where the app wants to install. Most of the time, these apps request to use the "SD Card" mount point. On most Android devices, even if you do not have a SD card installed, you will still have a SD Card mount point, which simply points to another location within the phones storage. It turns out that in this case, the S4 we were working on, had a SD card installed, but it was defective. So the installer would attempt to perform the installation step, but since the SD card wasn't responding appropriately, we would get this "Invalid download URI" error. After the card was removed, the Play store began functioning normally and apps would install without any issues.
Hopefully this helps everyone who had no success with the cache clearing and permission change solutions.
I wanna bump this to say thanks to the op and xda in general I been fighting with the aopen Opensign tablet10s that uses some hacked apon version of ics trying to get gapps working this thread was the final piece of the puzzle
THANK YOU

Bauhn AT-HK97 root

I have bought new Bauhn tablet AT-HK97.
I tried lot to find method to root it.
It does not have volume Button, and drivers are also not available.
Specifications:
Rockchip 3188T
Cortex-A9
Quad Core
1.4 GHz
Android 4.2 .2 Jellybean
I want to root it because, ts system storage is of 1GB , which is not enough for me. And internal storage of 16 GB, it tried lot to install apps in 16GB storage but all fail.
Any resolution for this yet? I have the same problem
Rooted but not Bricked
Hi there those interested. I have been procrastinating due to illness but I have located an update image and loaded it onto my external SD card. After installing Kingroot which gave me access to the root directory, and a file manager which could manipulate root, I moved the update IMG to the root. Howerever, when I rebooted, it seems the r/w reverted to r/o and caused an error. Subsequent attempts to run the update removes the .IMG file from the root before it can suggest the upgrade. I suspect the culprit is Kingroot which knows that an upgrade will uninstall it. I have reset to factory data and was able to disable Kingroot but it still hangs in there waiting.
Amazingly, the unwanted .IMG file has been moved to the inaccessible internal storage.
My next option is to try a rooting method that doesn't take over my system. Any suggestions?
There options for removing Kingroot but they seem to just replace it with similar monsters.
Also, 'root genius' is a method which is used from a PC. Has anyone any experience with this?
I guess the device is rushing on to 3 years old and any owners and users may have moved on to later androids.
However, I find the device still quite useable for my old eyes. I just wish I did not need to clear out data to download app updates.
Any help would be appreciated
