Nice thread.
Makes me remember those times i had to navigate the chinese website of OPDA.Thank God for Google translation.

Hello fellow members! Please come to my rescue. I have used coderus hacking method (UMUNokiaHack) without using cert and key severally. And i just had little blocks on my E63 and i had to format it as usually using hard format this time around (*+3+send). Now, i want to hack it back using the same method i had used time without number and this particular hacking softwares: UMUNokiaHack, Rompatcher, and installserver and even xplore for unhacked phone that am supposed to use to extract the installserver can't get it installed on my phone again. Those softwares keep telling me 'certificate error contact the application supplier'. And some other applications keep telling the same story. I dont know what to do now. Pleaseeeeeeeeee!

Please which app are we to download.?
