If your phone doesn’t boot into download mode and you have a black screen after flashing froyo, here’s how you unbrick it. It has worked for many folks.
Instructions:
- Prepare odin with the firmware u want to flash (in my case was gingerbread 2.3.3) and get it ready to go.
- Remove battery, SIM and SD card, next connect your galaxy ace to the computer.
- Hold Volume down + Power + Home button at the same time.
- Insert the battery and wait a bit.
- At this point Odin should have detected your SG Ace ( Yellow rectangle should appear)
- Click Start button in Odin and wait about 5 min.
If all goes well it should come back to life.
You should know how to flash firmware using ODIN.

Ace Tips 
hey this is the first im tryin to root my samsung galaxy ace.but i downloaded clockworkmod 4 before i rooted the phone and installed it from recovery.my phone keeps freezing on the SGA menu.and advise
Hi,
My ace is bricked when I tried to downgrade from CM7 to GB2.3.7. Hope it happened due to disconnection of the phone from from odin twice. Now my ace didnt turn up and shows nothing then the black screen. It might be bricked severely. Any suggestions…
i applied an update with clockwork and it just went black .. would love to know if this is fixable i loved my ace lol
What was in the update?
original froyo rom
willing to use whatever will fix it lol i dont care really
but the originial froyo rom isnot available in flashable zip. You might be using a custom froyo rom which is stock like available at xda. Simply flash via odin any stock rom either froyo or preferable gingerbread. The tutorial is available on the site.
still keeps sticking at setup connection tried changing usb ports with both froyo and gingerbread samething with both so i guess mine is unrecoverable lol unless their is something else to try
Are you able to boot into recovery (power + home key) or download mode?
download only black screen but when i plug in and do like you posted it shows the yellow square like it is connected but it says port 6 not port 5 i dont know if that makes a difference or not .. i know before it connected as port 5 when it was working
but when i tried this method it does everything but stops on setup connection and just sits there waited up to 10 mins nothing happened
hey pls pls help me when i press switch on button nothing happen i thing my phone was bricked when i root it it works correct for one i try to remove battery and restart the phone it start normally bt a day when i want to restart the phone and when i m pressing switch on button nothing happen plz plzzz help mei now what to do ????
i try 3 button combination,it didnt work.
i am using dxkpb 2.3.4 on galaxy ace, i have a nandroid backup,
then i flash gingerreal 7.2 rom and halt in the middle,
i turn it off and try to reboot it,but it wont start.
help
it says ‘cannot open usb serial port:5’
How did you brick your phone? This method doesn’t apply to all cases.
