I've never seen Error code 1233 in my store (top 100 in the nation) and I can't find it as a Sprint error code in the database. The only information I can find about it around the Internet is specific to HTC devices and it seems to be related to rooted phones unable to get updates. So I don't think it's a Sprint-specific error, more it is an HTC-specific error code.
You probably have resolved this issue by now, since it has been several months since your original post; however, I wanted to let you and anyone else receiving this error code know that I was having this same issue with my HTC Evo 4G phone and found a solution... Here are the steps that worked for me: 1) turn off the phone, 2) Remove the Battery, 3) Remove the SIM card, 4) Reinsert the battery, 5) Reinsert the SIM card, 6) Turn on phone and run the updates in this order - Profile and then PRL. Now my phone works better than it ever has.
Hi - I also am receiving this error when I try to do system updates. BTW - this post is specific to the HTC EVO 4G LTE - which I don't believe that you can remove the back to expose the battery??? I've had my phone for over a year and this just started happening. The symptoms are that the internet is VERY slow....I don't have insurance on the phone and would like to resolve myself if at all possible. Any help would be appreciated!!
We have the same problem on two HTC EVO phones in our office. Both give this error message on all phone updates (PRL, firmware, etc.). We have done factory resets, and then the updates work briefly. After a few days, we get the error message and cannot update. Shutting the phone off for three-plus minutes does not help. I assume some app we have installed is causing the problem, but I have no idea which one. We need several apps to use these for our business.
