OVERVIEW:

The Topelotek Meteor (T07D) is a very affordable, very basic, low-spec 7" Android tablet. As reflected by the above hardware specs, this tablet is by no means spectacular with regard to performance potential. Nonetheless, for the pricetag (typically about $25 or less), the Meteor T07D is not a bad deal. Like many Chinese tablets of its kind, stock firmware can be very difficult -- if not impossible -- to locate. However, this device does ship with a couple of extraordinary features: an unlocked bootloader and insecure boot image support (ro.secure=0) out of the box. As such, rooting and customizing this tablet are fairly simple tasks, as is pulling firmware images from the device's partitions. This firmware package is constructed from unmodified stock partition images (/system, /boot, /bootloader, /recovery), which can be installed using a few rudimentary fastboot commands, and can be beneficial in restoring a device that is soft bricked, stuck in a bootloop, etc. Installing this firmware package per the instructions below will restore your Topelotek Meteor to a stock factory state.

DISCLAIMER: By proceeding further, your warranty can be rendered null & void. (However, because the device ships OEM unlocked, out of the box, your warranty may or may not be affected. You will need to make this determination on your own.) As with any other system-level procedure, installing this firmware invokes the possibility that your device could be damaged or rendered completely inoperable. While I have thoroughly tested this firmware on my own device, I will not be held liable for anything that goes wrong during your installation of this firmware. By proceeding, you are taking sole responsibility for the integrity and operability of your device.

PREREQUISITES:

For this installation, you will need a PC or Mac with the latest Android platform tools or the latest Minimal ADB & Fastboot utilities installed. Visit this thread for download links and instructions: https://xdaforums.com/showthread.php?t=2317790 Please give [MENTION=3558630]shimp208[/MENTION] a tap on the THANKS button if you use his work. This is a link to the July, 2019 Minimal ADB & Fastboot thread by [MENTION=7752429]K3V1991[/MENTION]. https://xdaforums.com/android/software-hacking/tool-mini-adb-fastboot-2019-06-30-t3944288. Again, please give thanks if you use the developer's work.

Also, you will need to install the correct ADB and USB device drivers for this tablet.. A simple Google search for "Allwinner-A33 ADB & USB drivers" will provide links to these files, as well as guidance for proper installation of the drivers. As mentioned supra, this tablet ships with an unlocked bootloader. Nevertheless, you will need to go to SETTINGS>ABOUT TABLET and tap Build Number 7 or 8 times until Developer Options are enabled. Then, you will need to check the box called OEM Unlocking. Once this is done, your device bootloader is unlocked for all intents and purposes.

INSTRUCTIONS:

1. Download the firmware package from the below link and extract the contents of the archive to your ADB & Fastboot directory on your PC;

2. Boot your device into fastboot mode. One way to do this is by connecting your device to your PC with a quality micro USB to USB syncing/charging cable. Boot your device up, ensure USB Debugging is enabled, and open a command prompt on your PC in the path of your ADB/Fastboot directory. Execute this command:

adb devices

If properly connected, the command window will return with an alphanumeric string that represents your device serial number. If you do not see confirmation of a proper connection, check your driver installations, your sync cable, and/or try another USB port.

(In the event your device will not boot into the Android OS (soft brick, boot loop, etc.), you can boot directly into recovery mode/fastboot mode by using hardware key combinations. However, I am not familiar with the hardware key method, so you will need to research the proper procedure.);

3. Once properly connected, execute the following command:

adb reboot bootloader

Your tablet will now boot into fastboot mode. Your device screen will simply display the white Topelotek logo lettering amidst a pale blue screen. Open a command window once again in your ADB/Fastboot directory;

4. Execute this command:

fastboot devices

Once again, if properly connected, the word "fastboot," or your device serial number will be displayed in the command window;

5. Once fastboot communication has been established, execute the following command set:

fastboot flash bootloader bootloader.img

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash system system.img

fastboot erase userdata

fastboot erase cache

fastboot reboot

(Please note that system.img is a large file. Fastboot will automatically parse this image into a series of sparsechunks and systematically flash them to your device. This process can take up to 5 or more minutes, so just be patient. To avoid any possible issues, it is imperative to be using a current version of either the Android platform tools or the Minimal ADB and Fastboot utilities.)

Upon reboot, your device should be restored to a factory stock state and be running on the latest available firmware version.
