Loox n5x0 series rom update

[sp3dev]

heh, i`ve researched on the loox n5x0 series (htc maria?) rom format. now we can create custom roms.
Loox n5x0 OS_xxxU.nbf header format
total 42 bytes header, the rest is not crypted os rom image (what we usually call nb0 or n_d)
4 bytes - model name (N500, N520 or N560) + 11 bytes empty (filled with 0x00) +9 bytes version (e.g. 1.22.0001) + 1 byte 0x20 (space) +3 bytes language (e.g. ENG, ITA, GER) + 2 bytes empty (0x0) +4 bytes - reversed crc32 checksum (if we have, for example, 1163FCED, then we write ED FC 63 11) + 4 bytes - size of decrypted part (reversed somehow? we have 2100000 and write 00001002) + 4 bytes - rom base flash address (seems it it 80400000, we type 00 00 04 80, don`t play with it)
all this is true for OS_yyyU.nbf ( yyy means rom version), bootloader nbf is coded otherwise, it is usually named BL_xxx_G3.nbf or bl_xxx_G4.nbf. xxx - bl version. I suppose you delete file bl_xxx_G4.nbf or bl_xxx_G3.nbf. new pda`s come with g4 flash, it will be killed with g3 update. and, anyhow, bootloader update is always dangerous and not recommended.
wait a bit - in some days i`ll post a tutorial how to extract os rom image from n500/n520 and probably n560 pda.

I am eager to update the software of my N560... I would like to try the new Windows mobile 6. It's pretty annoying that this really good device cannot be upgraded somehow..

Well, hope to hear something soon..

No WM6 yet, but

http://4pda.ru/forum/attach/805977/n....AKU.3.5.2.rar - here is the rom with aku 3.5.2 for n560

For Loox C550
http://4pda.ru/forum/attach/808633/P...50FlashTool.7z - here is the flasher for c550, download it, download aku3.5.2 for n560, overwrite the files from the n560 update and open OS_213u.nbf with winhex and change n560 to c550

If you have german/french/italian/spanish pda but want to use this update, edit the nbf with winhex and change ENG to FRA/GER/ITA/SPA

Be sure to remove the password (fsc secure lock) before flashing

getting my n560 ready to flashing... go-go-go!

I have a spanish N560 pda. I wanted to upgrade its rom.

I did everything as indicated:

- open pda and put it in the cradle
- connect cradle to the power and the usb to my WinXP laptop
- in my XP machine activesync (4.5 spanish version) connects and recognizes my pda
- check there is no password protection in the pda (there was none before)
- unpack n560.Alex_DFR_.AKU.3.5.2.rar and open with WinHex OS_213U.nbf; change ENG to SPA; save file
- execute PocketLOOX5xxFlashTool; in the end I get this error:

"The language in this Flash Image update () differs from that on your device (SPANISH)!"

Well, I did again and again and again... same error...
Any suggestions???

PS: I would like to put its new rom in english, if it's possible!


Thank you
