question for boot loader
 

I got 2 Nokia 8290, v5.06 and v5.07...<br />both have Flash ID: 00B0000E8

I can flash the v5.06 with no problem, however, when I try to flash v5.07, it says

Loading Boot Loader...<br />Phone does not reponse...

Since they both have same Flash ID, won't the boot loader be the same as well??

Please help!!<br />Thanks!
