UPDATE 7 feb 2013: THERE IS A NEW VERSION OF THAT THING IS AVAILABLE, THANKS raandoom! http://talk.maemo.org/showpost.php?p...1&postcount=55
--------------------------------------------------------------- V This is my outdated thoughts and solutions V --------------------------------------------------------------- Hi all. I've researched into NOLO's binary for two days and found out, how to change the main color of NOKIA's logo at boot. Also i've explored image format as deep as i could with only hex-editor and Notepad++. May be if i'll try to use IDA, i'll understand it all, but not now. :confused: BTW, i threw out my laziness and wrote a GUI for patching "secondary" images, where NOLO is located. NOLO Logo Patcher v0.2 :cool: http://i.min.us/ijqk0I.png (Attached to this post) It provides these main functions:
Comment: In NOLO color is defined for a rows (not pixels), with two bytes (from 00 to FF each). I haven't figured out, how colors are computed by NOLO's code, but we can change that bytes and it works! ;) There is some examples and photos from earlier tests: Greenie http://i.min.us/jjhzdQ.png (3:0 -> 2:5) Improved classic http://i.min.us/jjlSgA.png (0:15 -> 0:0) My favourite logo :o http://i.min.us/jjmye6.png (128:128) bars1 & bars2 http://i.min.us/jjqko2.png (254:1 -> 56:199) http://i.min.us/jl7IfM.png (1:254 -> 199:56) Gradient and color madness like that cannot be done with my utility (it hasn't any button for) http://i.min.us/jjm8Jk.png http://i.min.us/jjmvWy.png HOW TO USE (note: you may skip steps 1-2 if you are running Windows and can't use 0xFFFF)
That's all. I'll appreciate any suggestions and comments. Many thanks to jacekowski! Files on his site helped me to locate pictures in secondary image. |

Hi! Mind sharing also the manual way for us who wants to know how it was done?

Re: [Announce] Changing Nokia's logo colors in NOLO
That's a tiny step towards revese engineering NOLO, which is inherently a good thing.

I'm quite liking this image, even if it was an earlier test result

http://maemo.jacekowski.org/binary/nolo/ . I've found out, that pics 1-2-3 are in a "secondary" image and represent the RD icon, logo, usb icon respectively. So, now i'm know, where is NOKIA picture located in secondary. Then i've C&P HEX representation in Notepad++ and started analyse. Here is my little screencast:
It's impossible to change image entirely without disassembling NOLO binary. +IRC log where jacekowski explained how to find location: http://mg.pov.lt/maemo-irclog/%23mae...01-14.log.html |

Re: [Announce] Changing Nokia's logo colors in NOLO
Thanks a million !!
this looks interesting, I will look into it tomorrow .. if the text can be made black, and the background made black for NOKIA word to be invisible that would be GREAT ! Can we replace the text completely ? also, since you started doing that kind of stuff, can you disassemble the binary into arm assembly, we can study what initializations it does exactly. |
