    Default Bizarre issue with Zeepad 7.0 (Android 4.2.2)

    Hello, my apologies in advance for this lengthy post, but I wanted to provide as much information on this issue as possible. Anyhow, I received a Zeepad 7.0 Android tablet as a Christmas gift last year. Regrettably, I known little about this brand and the ones who bought weren't able to afford any well-known brands. Here's the specs for this particular tablet below based off its box and user manual.

    • Model: Zeepad 7.0
    • OS: Android 4.2.2 (Jelly Bean)
    • CPU: Allwinner A13 Cortex-A8 1.2 GHz
    • RAM: 512 MB
    • ROM: NAND Flash 4 GB
    • LCD: 7" Capacitive Touchscreen with 16:9, 5 Point, and 800x480 px resolution

    I experience a major issue with this tablet this past Monday when a game app was auto-updated. This game app has routine updates that adds new content and adjusts game mechanics. Some updates are announced beforehand and must be installed manually via Google Play. A few "stealth" updates, however, pop up out of the blue and auto-install on their own. After the latest "stealth" update, I didn't noticed anything unusual as I played this game app, logged off, and turned my tablet off for a bit. However, when I tried to power my tablet back on, my tablet kept freezing on its third boot up screen. For those unfamiliar with this tablet, I'll list its three boot up screens below.

    Zeepad 7.0 Boot Up Screens
    1. Gray screen with "Zeepad 7.0" and "Android 4.2" in white font.
    2. Green screen with "Android" mascot and "Android" name in green font.
    3. Gray screen with "Android" name in light blue font.

    I suspect that "stealth" update somehow caused this issue because it was the only thing I installed the previous weekend. I tried using my tablet's wipe data/factory reset in the Android system recovery <3e> menu, but it still froze on the third boot up screen.

    Frustrated by this setback, I reluctantly chose to flash an authentic Zeepad 7.0 firmware from Zeepad's website. Although this process restored my tablet, I soon discovered it wasn't the exact firmware this tablet originally had. One of the major differences between the two firmware update was my two Internal Storage partitions, which I'll list below.

    Pre-installed Firmware
    • Apps' Internal Storage - Total space: 0.98 GB
    • System's Internal Storage - Total space: 0.98 GB

    Firmware from Zeepad's Website
    • Apps' Internal Storage - Total space: 504 MB
    • System's Internal Storage - Total space: 1.50 GB

    As you can see, my tablet's Internal Storage is no longer evenly distributed, which I find baffling. Other bizarre changes include the absence of the Google Play icon on the home page, some extra icons in the navigation menu, and an apparent lack of screen rotation despite being enabled. As for that internal storage issue, I successfully rooted my tablet and linked its app Internal Storage to a Samsung 16 GB microSD Card. However, a few apps including that one game app won't boot, so I flashed that downloaded Zeepad 7.0 firmware again for the time being. I feel totally shortchanged by this issue as 504 MB for apps is quite limiting, especially for apps that become larger after updates. Is it possible to modify a firmware image file to even out my tablet's Internal Storage distribution without rooting?

    have you tried reinstalling the software on your tablet? maybe that will help?

    Do you mean reinstall from Setting > Backup & reset > Factory data reset? I just tried that, but it only reset to that downloaded Zeepad firmware with the 504 MB/1.50 GB Internal Storage split instead of my tablet's original 0.98 GB/0.98 GB Internal Storage split. I also tried using Android system recovery <3e> > wipe data/factory reset, but I'm still didn't get my original firmware back. I'll try looking into that apply update from adb option.

    I've been trying out a few other options within the past few days... with mixed results.

    1. I downloaded the firmware for the Zeepad 7XN, which is roughly similar to the Zeepad 7.0 I own. Despite multiple attempts, I won't able to install the 7XN firmware on my 7.0 tablet.
    2. I tried using that apply update from adb option on the Android system recovery <3e> menu to install a few other firmware updates. However, the installations for those updates ended up being aborted.
    3. I flashed another firmware from another unfamiliar tablet brand named MaPan. Luckily, this firmware actually installed and it evened out my two Internal Storage partitions at 0.98GB apiece (which was their original size). However, my tablet's touchscreen became incredibly unresponsive and its Android System Recovery <3e> menu was empty except for its Android mascot background image.

    I chose to reinstall the Zeepad 7.0 firmware I downloaded from Zeepad's website (which I'll dub "backup firmware" for convenience) as I weigh my next options. Other ideas I'm considering include trying out other firmwares and perhaps editing a copy of that "backup firmware" in Ubuntu to manually set its Internal Storage partitions back to 0.98GB apiece (if that's even possible).

    I've been trying out a few more firmware images for my tablet, but none of the latest ones were compatible. To keep from having to download and test so many potentially incompatible firmwares, I wish to simply edit a copy of that "backup firmware" to resize the apps and system's Internal Storage partitions on my tablet and refine a few other things if necessary. Here's some info on my tablet's current partitions as well as its Internal Storage and Nand info.

    Major, Minor, #Blocks, Name
    93, 0, 16384, nanda
    93, 8, 16384, nandb
    93, 16, 32768, nandc
    93, 24, 1048576, nandd [/system]
    93, 32, 524288, nande [/data; Internal Storage #1]
    93, 40, 16384, nandf
    93, 48, 32768, nandg
    93, 56, 327680, nandh [/cache]
    93, 64, 262144, nandi
    93, 72, 1572864, nandj [/mnt/sdcard; Internal Storage #2]
    179, 0, 15351808, mmcblk0
    179, 1, 15348736, mmcblk0p1 [mnt/exstd; microSD Card]

    ROM: 4GB
    Internal Storage (Apps' Total space):
    > 0.98GB (before "backup firmware")
    > 504MB (after "backup firmware")
    Internal Storage (System's Total space):
    > 0.98GB (before "backup firmware")
    > 1.50GB (after "backup firmware")

    I tried installing Ubuntu via dual boot to resize my Internal Storage partitions back to 0.98GB apiece, however, I had some difficulty getting that program to run on my PC. I've since opted for Cygwin instead, which has been quite helpful so far. After using the Partition Table app, I discovered that the partitions I need to resize are nande (504MB) and nandj (1.50GB). My goal is to found a way to subtract 520MB from nandj and add it back to nande. Regrettably, I haven't had as much assistance from this forum as expected, so I'll continue researching this issue on my own and provide occasional updates on my progress.
