Help Stuck at boot logo and keeps restarting

coast23

Lurker
After charging my phone yesterday, I found my phone constantly restarting and not going past the boot logo. I haven't rooted the phone or installed any custom OS.

I tried recovering by flashing with stock firmware (I can't insert links to instructions as first time poster). I also tried factory reset, cache wipe, restart after installing firmware.

Any ideas how I can fix this or do I need to send it back?
Thanks,
 
Thank you for your welcome mikestoney. I bought the phone in October, so still in warranty...although I am still looking for the warranty paper.


Hi SUroot, I should have given these details in the beginning. The download mode says:

Odin mode
Product name: GT-I9300
Custom binary download: No
Current binary: Samsung official
System status: Official
 
Thanks. Symptom sounds like half sds but that often sets binary to custom. Return it for repair to samsung or your carrier
 
Welcome to the forum coast23

You should be able to post links now so would it be possible to give the link of the instructions you used. It's a long shot but there could be something in the instructions which*stopped*the flash from working.
 
Thanks shotgun84, The links are here and here, I followed the instructions as carefully.

Does anyone think I voided my warranty by trying the above methods?
I will try sending it back and see what happens.

Only that ^ can void your warranty really, and everything there looks fine.
 
Yeah everything looks ok with that guide so the problem is probably lying deeper so it'll probably need to be sent to Samsung. I take it Odin said pass when you tried. I've seen something similar before where everything appeared to work but the phone wouldn't boot after. They were on jb when the problems first started and managed to get their phone to boot by flashing ics firmware when all jb firmware they tried had no luck. It's the same theory the other way. So if you were on ics go for jb. I think it might be something to do with the bootloader being changed when you switch between different versions. No guarantees but maybe worth a shot.
