[Q] i9300 keep rebooting and never turn on

bootloop

It seems you are stuck in a boot loop. Try clearing the cache & perform a full factory wipe. Then reboot your device.
Hope that helps.

thanks for answer. But I try that several times. Nothing changes.

Also I try partition wipe too. Sometimes I can see Samsung logo but I cant go further.

Click to collapse

If you've cleared the partition structure then you've turned a possible soft brick into a hard brick, you'll need a new motherboard now.

Try flashing the rescue firmware, from the thread in general, but I wouldn't hold out any hope.

same problem but worse please help

HI guys i have exactly the same problem but my bootloop was caused by installing recovery through the cwm app and then rebooting to recovery through the app. i rebooted to recovery with an app before and it caused this aswell ...however back then my volume down button was working. i fixed it last time by going into download mode and flashing philz recovery however i cant enter download mode or recovery or boot into system.
PS: my phone doesnt boot into recovery it comes up with the samsung galaxy s3 gt 19300 logo then it comes up with the cwm recovery icon in the middle of my screen and 'clockwordmod recovery v6.0.6.4' at the bottom of the screen then restarts itself.
i dont know what to try i have looked around, didnt want to create a new thread just wanted to find out if anyone has any idea of what i can do except for buying a new volume down button thats my last resort apprently its £35 to fix
easy way to fill up you thanks meter guys as any sort of input and advice is extremely appreciated.

alphadavid99 you fried your lcd when you flashed cwm made for note in the other thread.

Hi i have the issue... I am able to get in Recovery and Download Mode.

While in recovery i had formatted the whole internal memory and tried flashing about three AOSP ROMs (Formatting each time before Flashing) but the only result was the endless boot up screen (not boot loop).

Then i tried flashing a sammy ROM and it worked...

Could someone tell me why am I able to flash Sammy ROM but not AOSP (such as ARCHIDROID & SLIMBEAN).

My Model is GT-i9300
Current Modem - XXUGMK6
Current ROM - S4 Revolution ROM (TM)

Thanks in advance for your time if someone has any suggestions
