[Samsung Galaxy Nexus] pepe_binefar:
Thanks!

Hi man! I have created an account just to thank you for that!

and by the way, I used an alternative method to ****Docomo

Until version 4.0.3 i was using one script which directly changed the nv_data.bin file and created a hash for the md5, but suddenly it stopped working with ICS 4.0.4 (now i know why...)

I have checked your theorie after running this scripts and Eureka! unlocked again!, just copying the value in nv.log

for if you are curious about it, i copy the script i am using ;) which i found in a webpage (sorry i don't even remember where)

I adapted it to my computer and did slight changes to make it run

now it works again :)
