this update is for 9900 only, don't even think of trying to install it on 9930 . hopefully the cdma carriers will soon release a similar update for the 9930 bolds.
Thank you so much!!! I updated to .503 a couple days ago and today it died randomly. Woke up this morning and it wouldn't turn on. I was about to throw my 9900 threw the wall until I saw this. Downloaded .540 official release. Deleted the old .503 from control panels, deleted vendor then connected my 9900 to my pc. Clicked update and it started to boot up again!!!
My 9900 just get bricked last night with flashing red led.
After looking many forum where people say there is no other choice, I saw this thread and I download the .540, and I could reload the OS following your advise.
I had a phone brick (or so I thought), but it turns out it wasn't charging. The battery icon changed to a little "plug" icon (not the lightning bolt charging icon). After a few battery pulls it would charge. After a software update to 7.1.0.74 I haven't seen the same problem.

My understanding then was that it was nuked and not bricked. By defn, a bricked phone can't be brought back...
i changed phones the other day to my old droid 2. put my 9930 down with 80% batt life.went back to use my 9930 for the alarm clock two days now ,and it was completly dead. black screen . plugged in the charger it showed dead batt.batt with thunderbolt showed on the screen.my heart started pounding oh my god what should i do now.I watched and watched and the batt started to charge,so i left it on charge for two hours and it was ok.But should it have died after two days of not useing?
Turns out in the process of making somewhat of a hybrid with the .503 radio and the .585 files my 9900 nuked. I was stuck at the blinking red LED for a good 10 minutes until I figured I'd just go about installing the OS as I would if I were to install a fresh upgrade with a clean wipe using the command prompt method to bring up the loader.exe with no jvm. Worked. I think everyone's nuked berries should be able to get revived now. As far as I know this method has worked for me, if someone else has tried it and it hasn't worked please report back.
. hopefully the cdma carriers will soon release a similar update for the 9930 bolds.
Mine bricked two nights ago and Ive been working like made to get it to work.
