My friend has a UK S3 on the 3 network.
The other day when turning it on it it just gets as far as the first screen with the white text "Samsung galaxy S3 GTi9300". It gets no further and remains on that screen until the battery is pulled. If the power button is held it simply powers off and then immediately back on again.
Whilst she has dropped the phone in the past it has only suffered cosmetic damage and the occasional non requested power off and on(yeah the drops may have damaged something internally). However, no further falls/water damage etc was experienced by the phone when the problem above occurred.
I should also stress that the phone was not rooted and she thinks was on 4.3.
In an attempt to fix it (i have a rooted s3 so know a bit about the phone) i was able to get the phone into recovery mode. The below picture is what was displayed and did not look good.
We tried wiping the cache and when that was unsuccessful at completing, tried a factory reset. This was also unsuccessful, citing issues mounting E:
I was next thinking of trying to reinstall the firmware via Odin. However i would be unsure of exactly which version to use, given her uncertainty of if the phone is indeed network branded and on version 4.3 of android. Is there any way i can check this with the phone in its current state?
Does anyone have any ideas what to try next or what the issue may be? Thanks
