Having some issues with my upgrade. Have done it probably 5 times in the past with no issues, once on this particular phone (recently had to buy another as the first one tried to surf- yes, it's the exact same model).
Anyway. After backing everything up last night around 2am, went ahead with the wipe using BBSAK. Phone rebooted to the "Reload Software 507" screen, but BlackBerry Desktop Manager won't connect, ie
Followed instructions, first installed the base OS, 8330AMEA_PBr5.0.0_rel724_PL188.8.131.52_A184.108.40.2068_Boo st_Mobile.exe
and then the hybrid, 8330 Hybrid v4220.127.116.11.exe on top, deleting the Vendor.xml file of course, and the Application Loader is .. empty. Have deinstalled/reinstalled the Base OS and hybrid OS several times hoping I somehow didn't get the directories right the first .. several times, but everything seems to check out. The first time I upgraded this phone was to the lyricidal hybrid build, which was about a week ago. No issues there. Had the BBTweaks hybrid installed on the first phone and preferred that over the other, which is how I ended up here.
(Here's a shot of the screen)
As for the error in the first screenshot, I read somewhere that disconnecting from the internet entirely helped some folks, but not me (yay..)
