You're free to do what you want with your device :) + + Seriously. Flashing a device is not a safe thing, so I give no warranty + of what will happen to your device when using this tool. + + BTW, after a huge number of tests I can say that these devices are hard + to brick, but if you are scared about bricking your device you should + use the flasher provided by Nokia, it's better for your heart's health. + + +*) What can I do with 0xFFFF? + + Actually 0xFFFF allows you to: + + - flash separated pieces of the firmware. + - retrieve information about the device + - reboot de mother board + - extract the current firmware pieces from the device (reverse flash) + - set the USB host/slave mode + - set the R&R mode + - identify firmware pieces + + +*) What is NOLO? + + NOLO is the 'server-side' part of the flasher from Nokia. NOLO means + NOkia LOader and it's composed by two pieces of the firmware that are + flashed together. + + On the n800 firmwares, these two pieces are distributed in a single + file, but when flashing a n770, NOLO requires to provide the xloader + (without commiting) and then the secondary piece. + + This piece of software is closed source and is the responsable of + handling the requests from the client-side flasher. It provides a + query-like interface via usb control messages for doing different + actions on the device. + + +*) How can I identify my device? + + Theorically n770 and n800 have different USB device ID, but this is not + true at all. The first series of the n800 comes with the same usb-id + than n770. That's weird! + + So, the only way to identify the device is by asking nolo for the version + information of different pieces of the firmware. This can be faked, because + you can flash n770 stuff on n800 and viceversa, but it's not recommended + because it wouldn't work :) -- cgit v1.2.3
