I have a Samsung Galaxy s3 which I successfully rooted over a year ago though I never bothered with a custom rom. I have now purchased a note 3 so in preparation for selling the S3 I did a factory reset through Settings to clear out all my apps, data and personal information. That all went well and the device booted back into the normal system a couple of times (I didn't check to see if root had been maintained or not) This weekend I got it out to sell it only to find that it boots through the first part of the routine with the Samsung moving logo but then sticks on the static SAMSUNG screen and will not go further.
I am able to boot into TWRP so would I be able to download a stock rom from somewhere, insert a micro sd card with the stock rom on it and recover through TWRP? Alternatively I do have an old full back up stored on my computer - I could transfer this to the micro sd and restore this through twrp - I can see this was made through twrm as the openrecovery-twrp-2.3.1.0-i9300.tar.md5 is stored with it. Of course if this works I would still need to perform a reset to get rid of all the personal data etc so could end up in the same situation later.
What recommendations do you helpful guys have?
