These units are somehow idiot safe. So put the firmware on SD, put SD in slot, start unit with autoupdate. You should know that upgrading firmware on these units is not an ota update that keeps your data on the device. The upgrade procedure is an erasing all data batch task (in uboot I think), writing the image to the internal memory and voilą.
Regading the launcher, you can even exchange it completly. I disabled the stock one(too much bling bling for nothing) and I am using nova launcher which is really fast.
With the firmware in my post that I mentioned earlier, you got root rights, so you can use ES-Explorer for example, to browse all folders/system folders and check for saved apk.
But I recommend to avoid any apk that is written by the manufacturer, cause they are really buggy.
Have you try those combinations of other china HU (ex: power + rst?), I havent tried yet but thought it would be the same in theory as just few hardware manufacture & probably they did not spent too much on software customization
Regarding pre-requisition for firmware upgrade, just reconfirm:
- 2Gb microSD into GPS slot
- FAt 32, 32K allocation size
- Any MCU version? Mine is 20131125
I prefer Recovery & Boot loader possibilities prior to upgrading because I'd not like to brick the HU for very first days
Do you have specification for Factory Settings options, i just able to turn on the analog TV feature (could not scanned any channel yet
Any way to standardise system volume across application (mine, it's extremely loud for radio but tiny sound for Music)
More questions coming...
