[Q] AT&T trying to update Galaxy S3 while rooted & TWRP Recovery Installed
I just got my wife a Samsung Galaxy S3 I747 for ATT using Straight Talk. I purchased one for my self about 3 months ago, same model. Both were purchased used, mine had 4.1.2 and my wife's has 4.1.1. I rooted and installed CWM Recovery on mine. I wanted to update my wife's to at least 4.1.2 like mine or even 4.1.3.
From my understanding, once you root and install a recovery mod, such as TWRP or the ClockWorkMod Recovery, that your phone will not be able to update via your service provider.
The problem is, I got her phone yesterday, and I tried to update it, but it kept saying it was at the latest update/firmware. I even installed Kies, but it reported the same thing. After a few hours, I decided I would root it and install TWRP and maybe install a new ROM with the FW on it later. Well, this morning, the phone reported that an important update was available. Somewhat confused, b/c I thought it couldn't be the FW b/c yesterday it said the phone was at the latest FW, and plus the fact the update is, as I thought, refused by the service provider or phone, when it is rooted or a recovery mod is installed. When it finished, of course it asked to reboot. I was curious how this was going to play out.
When it rebooted, it loaded the TWRP Recovery. Being still new to all this, I wasn't sure how to proceed, so I clicked the reboot button, but nothing happen, so I tried the shutdown button. The phone powered off with no issues. I turned it back on and it loaded successfully to the home screen. I checked the status of the update, and it said it failed. No surprise there, I'm just happy it didn't brick her phone during the process.
Is this normal? Should I just disable updates from my provider? Is it possible to install the update and then just reapply the root and recovery mod?
