Crucial Warning: This firmware package is exclusively for the MediaTek MT6580 Hotwav Cosmos V2 (board code D8050). Do not attempt to flash this package using Spreadtrum SPD tools, and never cross-flash with the Spreadtrum-based Hotwav Cosmos V4. Always choose 'Download Only' in SP Flash Tool; never select 'Format All + Download', as formatting erases unique factory NVRAM baseband calibrations and IMEI certificates.

Expand preparation checklist for Hotwav Cosmos V2
- Check the device label under the battery to verify the model reads Hotwav Cosmos V2.
- Ensure the 1950 mAh removable battery is charged to at least 50% or verify battery voltage measures above 3.7V.
- Install verified MediaTek MTK VCOM USB drivers on a Windows computer.
- Connect using a reliable microUSB 2.0 cable plugged directly into a rear PC motherboard USB 2.0 port.
- Back up any accessible personal files before flashing, as writing stock partition images will replace user storage.
Compatibility & Bootloader Notes
The Hotwav Cosmos V2 is built on the MediaTek MT6580 chipset with board code D8050. Unlike Spreadtrum-based Cosmos models, flashing this device requires SP Flash Tool and MTK VCOM drivers. Bootloader unlocking is not required for flashing stock scatter images in BROM preloader mode. Power off the phone, remove and reseat the 1950 mAh battery, press and hold Volume Down, and plug in the USB cable to initiate the handshake.

Frequently Asked Questions
Hotwav shifted chipset architectures between device iterations in the Cosmos series. The Cosmos V2 was designed on the MediaTek MT6580 platform (quad-core ARM Cortex-A7 with Mali-400 GPU), which utilizes scatter-based partition tables loaded through SP Flash Tool. The later Cosmos V4 adopted the Spreadtrum SC7731 chipset, which requires SPD Upgrade Tool and PAC container files.
D8050 is the OEM hardware PCB model code engineered for the 5.0-inch Cosmos V2 form factor. It establishes the physical address mapping for the display panel driver, capacitive touch digitizer controller, and the cellular power management integrated circuit (PMIC).
The "P12" tag denotes production firmware revision 12. In MediaTek ODM releases, production revisions incorporate factory bug fixes, improved kernel power management profiles, and finalized modem frequency calibrations compared to early pre-release builds.
The MT6580 utilizes a traditional non-A/B raw partition table mapped across eMMC storage. Core images (boot.img, recovery.img, system.img, and userdata.img) exist in discrete physical blocks alongside protected NVRAM sectors (nvram, protect1, protect2) that store unique cellular radio calibration certificates.
