The Original Titan

Brief description

The original Titan was released in December 2019. The early released devices operated with EMMC storage, while smartphones manufactured since around November 2020 use UFS chips, moreover, it can be either UFS v2.0 or v2.1. To further complicate things, we have an EU-compliant variant (commonly known TTEU /TiTan European Union/ or EEA variant) and a non-EU-compliant variant (commonly known as TTNE /TiTan Non-European/ or TEE variant - sorry, that's the best I could do for that acronym, and so assumptions follow based on that). Please note that though TEE-marked units explicitly specify operating in a trusted execution environment, both EEA and TEE models make use of that security feature. To add a bit more confusion to the mix - there seem to be no TTNE variants with UFS chips.

So, to sum it up, the entire device matrix consists of 3 entries:

This makes it a freaking p a i n to manage firmware and diagnose these devices if you get a brick on your hands with not much information available to you. Though from what I've been able to gather, if you're buying the phone directly from Unihertz these days, it's likely it has a UFS storage chip rather than an EMMC one.


Rather unsurprisingly the datasheets for the used chips aren't readily available. I've been able to found some in a few shady back alleys of the Internet, though.

So you've managed to bake yourself a fresh Titan brick, huh? Fret not - these things are impossible to kill via a faulty ROM, and what lies below is a sizeable collection of stock system software for this particular type of device gathered together from various sources around the Internet. There are a few requirements you need to get before you can start the recovery process.

▌If you're on Windows
You will need to install the Mediatek VCOM driver and extract the SP Flash Tool for Windows somewhere on your computer's drive.

▌If you're on Linux
Drivers are already provided by the Linux kernel, so you that's one less worry for you. Just extract the SP Flash Tool for Linux somewhere and run the flash_tool binary directly. Ignore the script. You will have to install QT4 provided by your distribution repositories in order for this version to work, or you can try this one if you're feeling lucky.

UFS firmware packages


Found this one here. Flashing it can result in what I call a "hard brick" that requires more effort to recover your device from.

Latest package for the UFS devices. Worked with my Titan.


As far as I'm aware there are no TTNE Titans that are UFS-based.

EMMC firmware packages
Each region has exactly one version compatible with EMMC storage chips.





OTA upgrade packages
These are flashable via recovery - they work for UFS and EMMC chips alike.
