could anybody explain what is this download mode?
As described in here How to root Innos A35 as I hold vol up +vol down 5 seconds and at the same time connecting the USB cable to my computer it shows up a removable disk and unknown drivers in windows 7.
My phone is also Innos A35 device locally sold as i35 from dialog telecom.
What are those? And what is this
But unlike the recovery mode, I didn't get a screen up. Is these two modes all coming from ROM. what kind of code is there on ROM. [Well in x86 computer I could review a opensource bios implementation, any idea on Android ARM ?].Where that consoles come from?
Where is uboot located? Is this download mode is a mode that programmed into a ROM, where I could not change it?
I have read the boot procedure of a typical android phone. But can't organize the info with this.
