I'd say get the original firmware directly from the Samsung website for this device and you should be able to flash it somehow via download mode. I could be wrong I've never been without recovery. Sorry I can't be of more help.

[Q] What are the causes why you can't unbrick your phone?

I know there are tons of questions here how to unbrick a phone. But, this is not about it.
I know you can't unbrick your phone if you messed up your download mode and you can't even boot up into download mode.
What are the causes why you can't enter in download mode?
How do I prevent destroying my download mode?
For others who are asking if they can unbrick their phones. I would answer you, yes as long as you have download mode you can do whatever you like. I have bricked my phone countless times already. But I am not sure until when my download mode will last.
I dont know if this applies for SGA but you can just use JTAG.
Some have lost the imei, this apears to be the only reason. It normaly happens through trying to unlock the phone.

@QNBT
thanks for your input. However I am asking ways to 'prevent' download mode from being destroyed
@Jusada
Does this mean if I don't brick my phone by unlocking, I can unbrick it by flashing.
And if gets bricked by unlockinge then I have to use jtag.?

i have a galaxy s and not the ace, so i'm not 100% sure, but you can only permanently brick your phone when you start messing around with the bootloader
download mode is part of the bootloader, so as long as you leave the bootloader untouched, you can always boot into download mode and reflash the phone

Using JTAG youre actually able to boot up without a bootloader in the phone, it supplies everything from the computer.
If you want to prevent it from bricking, keep away from network unlocking as jusada mentioned. Only flash stuff that is compatible with your rom.
Just curious: if I accidentally plugged out my phone while flashing (in download mode) through ODIN, what would happen? Would it be bricked?
Asking for theories, not practices.

No it wont. You can get into download mode again and flash a ROM. Had happened to me many times.
Wow thanks guys. Does a usb jig work when you messed up the bootloader?

i couldn't see anything displayed on my Samsung Galaxy ACE, even after the 3 button combo.. does this mean my phone is totally bricked?
I installed ROM manager and wen i tried to backup my current ROM, it shutdown and doesn't show anything now..
I'm in bad situation.. please advice me!!
by anychance the USB jig works?
In dis forum most of the people were briked their aces by using rom manager
it really does depends on whether it is a soft brick or a hard brick.

It don't allow media file to transfer? What are you meaning by this. Is this an error you get while flashing in odin/heimdall?

He can, because he stated that he tried to reset it via odin...
@OP , take a look at the USB port where you charge the phone... Do you see something wrong with it?...

the usb is ok, it charges the phone, connects to kies as well but not odin. i bought a usb jig as well. when i connect the jig it flashes "downloading" though it hard to see as its flashing non stop however nothing else happens.

oke thanks, just ordered one on Ebay. Probably have to wait a couple of weeks...

[Q] Well... In a delirious state flased international Firmware

Flashed* haha
So I have a US version Galaxy Player 4.0 - Flashed over a Korean or Chinese (can't read them obviously lol) So I can't get into download mode at all I have tried to force it but can't get her to go. To do it with Kies I need a backup of the original, don't have that guy unfortunately. I have googled stock backup's but I can't seem to find one, I am kinda stuck - I have tried Odin of course but no dice since I can't get to download mode.
If I can force brick it then it will go to download mode automatically but I can't get that either.
Thank you for the help
Jason
First off can you get into recovery, second: is it a hard brick or soft brick.
3rd of all: if you have a galaxy player 4.0 try to look for a stock ROM for your device on the Samsung galaxy thread

It boots to the OS no problem, issue is the buttons on the side don't get you to Download Mode because the international software has it looking for a physical home key that just doesn't exist. I have a stock rom waiting the correct one I just have no idea how I can get to doanload mode to actually flash it

Have you tried to get adb working then typing this command?
adb reboot download
It could help you get into the download mode. If it's not working, maybe you can try to use a usb jig to force your device to get into download mode.

I have tried this yes and I get a weird DNS error - I searched everywhere about resolving the error to no avail. I did order a USB Jig off amazon last-night as a back up because I don't know what else to do.
Is the touch screen working properly? If it's working upside down then you've flashed a part of the international firmware that there is no U.S. version of. That's why I have one Galaxy 4.0 that will never work again.
So a little update. I have gotten a USB Jig setup and I can get to download mode now. I flashed the original PID and Firmware through odin. However the touchscreen doesn't register and touch at all - Any Idea's there?
