I turn on my phone and it doesn't boot up. it only shows the at&t logo and "Boot loader 0.700 SW Version R272311_U_97.0 4.30R1_F Battery OK OK to Program Connect USB Data Cable

Try charging your phone.

If that doesn't help solve the issue, you might have a corrupt boot loader on your phone and you will need to take it in to your carrier's store / kiosk to get it replaced.

hello sir

probably you had pressed the bootloader buttons.
once the phone is diplaying a status message like you are having, it means that the phone is ready to be flashed. if you haven't do anything to your phone after displaying the message, try to remove the battery and put it back on. but if you had this status message during flashing, it will give you the same issue even if you remove the battery.

take care.

Boot loader corrupt. Phone has to be re flashed.

my phone now desaper all menu

your phone is going into bootloader mode that happens when you push asterik and pound on boot up if i were you id get a new battery

Take it to a mobile service center to have it unlock there for a small fee.

It has not completed the full unlock procedure that is why it is showing the above mention
"CALL SERVICE PROVIDER BOOT LOADER 0A.52."

you have entered the boot loader program by pressing*# and end call button i belive to continue just press the red button again

Try pressing the power button. This should switch the phone off. Then start up as normal by pressing and holding the power button.

The boot loader is corrupt, bring the thing back to the AT&T store.


I went through 3 of those.
