bootloader dynamic passwords

For information on the dynamically generated passwords the official RUU utility uses, read this forum thread [1]

set command

the set command takes two arguments, the property and the new value, both are hexadecimal numbers. Possible properties are: (flags are either 1 or 0, values are numbers)

property internal name internal description description
0 cEchoFlag Echo flag Wether to echo all input. 1 to show what you type, 0 to stay quiet
1 cOpModeFlag Operation mode flag Set to 0 for friendlier return values, or 1 for easier to parse return values (0 for users, 1 for programs)
2 cBackColorShowFlag Back color flag Wether to draw a background with text.
3 cShowInverseFlag Inverse flag Wether to inverse fore and background colors (1 yes, 0 no)
4 g_wFColor Front color value Foreground color, 16-bit number, 5-6-5 bit compression
5 g_wBColor Background color value Background color, see Foreground color
6 Unknown Unknown Sets complete screen to a specific color (see Foreground color)
7 Unknown Unknown Unknown
8 g_cCommQueueFlag COMM queue flag Unknown
9 Unknown Unknown Unknown
A Unknown Unknown Unknown
B Unknown Unknown Unknown
C Unknown Unknown Unknown
D Unknown Unknown Unknown
E Unknown Unknown Unknown
F Unknown Unknown Unknown
10 Unknown Unknown Unknown
11 Unknown Unknown Unknown
12 Unknown Unknown Unknown
13 Unknown Unknown Unknown
14 Unknown Unknown What to do after a reset. Set to 1 to go to bootloader after reset, set to 0 to start OS

info command

The info command returns specific info from the device. it takes one hexadecimal argument. The possibilities that are known are listed below

argument example value description
0 UNIVERSAL Probably either the device type, or the bootloader password
1 1.00 Bootloader version
2 (too long) SD Card information* HTCS + (some kind of CRC) + HTCE
3 (too long) HTCS* All sorts of device information + CRC + HTCE
4 HTCSQTEK_001(crc)HTCE HTCS* CID-lock + crc + HTCE
5 (nothing) Unknown
6 HTCST (crc)HTCE Unknown (same as radio rregion command?)
7 (too long) Information about the bootloader

task command

The task command takes one argument, and performs that 'task'.

argument action taken
0 Exits bootloader and turns screen completely black.
8 Resets
1E switches to eMapiMain+++ mode :S
28 Gives info on FAT partitions and does a hard-reset
28 55aa Restores DOC to its original layout
32 Returns Radio SecLevel
37 KITL output - requires task 32 first and for Level = 0
3C sends "+SA_USB_Init" and seems to reset the USB connection

rtask command

rtask seems to accept either just a type, or a value. (two hex arguments)

type possible values description
0  ? Resets radio
1  ? tells you to use 3 or 4 instead
2  ? Turn radio off
3  ? Runs radio image
4  ? Runs radio bootloader
7  ? Allows you to debug AT commands.
a  ? Talk to GSM bootloader.
b  ? Radio AT Command Debug. Talk to GSM AT cmd interface.
 ?  ? (more follow, but not all documented)

backing up the device with 'd2s'

Device needs to be SuperCID for this command to work, if it is CID locked you'll get an error from bootloader.

d2s 60000000 00800000 8M radio rom (First 8M, where the code is)
d2s 60000000 01000000 16M Full radio NAND chip backup (filled with FF)
d2s 70000000 00100000 1M SPL
d2s 70100000 04000000 64.00 M OS TrueFFS
