how to boot into dl mode? sm a526u model
I believe you. 1. Turn the power off. 2. Plug the USB cable into the pc but not the phone. 3. Hold vol + and - at the same time AND plug the usb into the phone as it turns on. Should take around 5-10 seconds after the combo

After flash via odin fail. Now my phone stuck in Vibrant logo. I can get into recovery mode but not download mode. When I try to get to download mode by pressing up and down volume buttons and plug the cable in, the charging screen pop up but not download mode. I can get into rocovery mode. That's really weird. What should I do
check your usb cable to computer
reset odin
pull your battery, put it back in
volume up/ volume down, insert cable

If you have gingerbread bootloaders the button combo for download mode is simply volume up + power button. If that doesn't work then wait for the usb jig to arrive..... How did you manage to soft brick your phone, what messed the phone up?

I have a Galaxy S2 I777 (ATT) that I have had on Cyanogen Mod ROM (which I love) for the last 6 weeks or so. Never had a problem until tonight. I was browsing a site and all of a sudden the phone froze. Nothing would work to unfreeze it. Tried everything I know and eventually took the battery out. Just in case, I replaced it with a fully charged battery.
When I tried to turn it on---nothing. I tried to boot into recovery---nothing.
Anybody have any thoughts???
Thanx in advance Rich:crying:
Have you tried getting into download mode? Once you can't get to recovery, Download mode is the next option, where you'll need to odin back to stock (I suggest UCMD8). There are several methods to get into download mode, I'll comb through a few of creepy's more recent posts to find them...

There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:
With the phone off (and not connected to the computer), and battery installed, hold all three buttons, vol- vol+ pwr continuously until the initial boot screen appears the second time.
Download mode:
1. With the phone off and connected to the computer via USB cable, and battery installed, hold all three buttons, vol- vol+ pwr.
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
3. With the phone off and battery installed, hold vol- (but not vol+ or pwr) while plugging in the USB cable.
4. Attempt each of the above three options with the battery removed from the phone. The computer will supply the power to the phone.
5. Use Android Debug Bridge (adb) which will only work if USB debugging has been already turned on in Developer Options, since you can't boot into the system to turn it on. With the battery installed and the phone connected to the pc via USB cable, use the command "adb reboot download".
6. Use a USB jig. With the battery installed insert the USB jig into the USB connector of the phone. Some have reported that this method works when no other method would work.
Thanx
I tried all of your suggestions except the USB jig. Don't have one; don't even know what one is. Unfortunately, none of them worked. But, I really appreciate your taking the time to respond

i tried the power + volumerUP + volumeDown and nothing on the screen
Tried plugging the USB to a computer and tired to put the phone in download mode , but screen was dead.
i tried replacing the battery with a new one (from ebay) and it is still dead. the battery show about 3.8V when i check the + and - terminals using a multimeter.

bricked = no sign of life under any circumstances
Try putting the phone into download mode when the battery is removed. Pull the battery and leave it out. Connect the phone to the PC via USB cable, and hold down vol+ and vol- (but not pwr). The USB cable will supply the power. Let us know if it will boot into download mode using this method.

Thanks for the reply.
I tried to put the phone in download mode when battery is removed, however there was no message/flicker either on the screen and the computer did not recognise any device. I held the vol+ and vol- buttons together for about 15 seconds.

Sounds like a true brick. The phone is getting old enough that it may not be cost effective to send it out for repair. But if you do choose to go for a repair, Mobile Tech Videos in LA has a very highly respected reputation here.

My phone switches off everytime I'm charging it
When I plug the phone into a wall charger, I don't even get the red light that says its charging. But I am able to get it into flashmode when its connected to a computer. I have already tried flashing a new .ftf file. Previously, the phone wasn't charging so I put it into fastboot mode to override the charging stuff which worked once. but now, I can't get any charge and the phone boots straight into flashmode
Try doing a full-blown "pmic oblivion" shutdown
Power button + Vol up (normally ~ 15 secs for "emergency shutdown") but keep it pressed for 45+ seconds
So in a nutshell:
Power button + Vol up (for 45+ seconds)
Then see how it behaves ...
Still doing the same thing. what does that mean?
