Hi all,
After double check the PID/VID officially used (registered) by Mediatek Inc. The following VID/PID maps to the corresponding USB interface of the firmware of cell phone. VID:0x0e8d, PID:0x0003: Mediatek BROM. VID:0x0e8d, PID:0x2000: Mediatek Preloader.
I will update Patch v6 for changing Andrey's previous comments.
You should show us a verbose lsusb of your 0e8d:0003 before changing Andrey's submission.
Season's Greeting Lars
Hi Lars, Oliver, and Johan,
Well, it's about 1:30 a.m. here in Taiwan. I can do lsusb dump tomorrow in Mediatek's office. But there are a lot of tutorials about hacking and flash method of customized firmware over the WWW. I can find one of the tutorial shows these VID/PID combinations has been used since 2014. (Actually they've been registered officially earlier than 2014.)
For example, please check the reference tutorial: https://mattboyer.github.io/PYaffs/2014/07/31/Hacklog%233.html You can check lsusb dump in this picture. https://mattboyer.github.io/PYaffs/images/03_device_usbview.png Both VID/PID of Mediatek BROM and Preloader can be found in INF file pasted in this tutorial, too. Sorry for the proprietary information policy I cannot paste them all, but the VID/PID set of BROM and Preloader are just exactly the same as described in this tutorial.
Hi all, Here is the lsusb dump of the BROM and Preloader state of the phone.
lsusb of BROM: Bus 001 Device 012: ID 0e8d:0003 MediaTek Inc. MT6227 phone
lsusb of Preloader: Bus 001 Device 011: ID 0e8d:2000 MediaTek Inc. MT65xx Preloader
