When it reaches about 29%, it just reboots and comes back with "Install Interrupted The software update could not be installed". When I do "adb reboot recovery" from a command window, I see a dead android with a red triangle and I assume that has something to do with it or is some kind of symptom. Is there anything I can do to get the latest stock image installed? Did I miss something in the unroot process?
SGH-I747 4.1.1 1747UCDLK3
I solved my problem by a convoluted process that I could not recommend but will lay out as best I can in case anyone is that desperate. I had re-rooted and un-rooted a couple times since my last post and finally decided to try a different stock image. I found a link to one in an article
how-to-unroot-att-galaxy-s3-sgh-i747 (sorry - not allowed to post URL)
The link is to stockroms.net. Really slow download - it took a couple hours. After the download (and unzip),
I attached my unrooted phone via USB cable to my computer.
Installed it with ODIN and watched the phone reboot
It seem to get stuck on the Samsung splash screen.
I went into recovery mode and noticed that - at last - I did not have the red triangle and no dead android. I tried wiping the cache a couple times from the recovery screen but it still seemed to get stuck at the splash screen (not sure if I waited long enough).
I finally did the factory reset from the recovery and it finally came back to life and went through the whole initialization thing. I confirmed a couple times that the red triangle was gone and noted that I had gone from Android version 4.1.1 to 4.04. Maybe that was the key or maybe I had a bad stock version of 4.1.1. IDK. But I started going through a series of updates. I am currently at version 4.3 and downloading what I hope will be the last update.
Started with 4.1.1 and used outdated stock image to go back to
4.04 - small update but version still
4.04 - cleared data from AT&T Update App to get around the wait 24 hours - got the update installed to version
4.1.2 - checked for update and got upgraded to
4.3 - check for update wanted me to wait 24 hours and I could not see how to clear the data - so changed the phone's date to next day. Automatically started downloading a new update - I'm hoping its the last
