[EVO 4G Q&A, Help & Troubleshooting] thelovatscout:
I know. It looks like a lengthy read. But all the information you could possibly need I've provided. Please let me know what you think. Also, I've done some searchign around but none of the scenarios I found were a result to flash back to stock sprint RUU.

The error reads as follows:

"Attention. A network error has occurred. Retry, or cancel and return to the previous screen."

What actually happens:

Anytime I open Marketplace, Facebook app, send a message through KakaoTalk or GroupMe, pretty much anything that uses the 3G, 4G data, it doesn't work. The message only comes up when I try to use the marketplace app. All other apps just say there was a connection error, connecting to the server, etc.

When I hit "Retry" it goes right back to the same dialog pop up, as if it doesnt even re"try". The top notification bar goes from 3G and then disappears, then goes from 3G and just continually disappears. It doesnt matter if I have 4G on or WiFi, it will just goes back to 3G when attempting to gain data, and then disappears and the error happens.

My Timeline of events:

I first had been running Synergy and everything was fine. Suddenly my wall charger (or any wall charger for that matter) stopped working when plugged in. The car charger still works, but no HTC wall chargers, odd. So I decided to use that insurance for good and bring it into sprint. Gotta unroot and all that jazz first though. I downloaded the "

RUU_Supersonic_1.32.651.1_Radio_1.39.00.04.26_release_171253.exe

" and found a way to connect my phone to the PC, and finished the wizard. Mind you, before I did this, I went into recovery (while on synergy) and did a dalvik cache wipe, data/factory wipe and cache wipe, then went back into hboot and ran the wizard from there. Everything went fine, the ROM install was successful, I no longer have recovery and it was the stock sprint ROM.

Where things got fishy...:

After it was running through all the constant reboots and things, I let the phone sit while I did other things. I came back to it, signed into my gmail and facebook fine, then went to marketplace. I started downloading all my purchased apps and since that was going to take some time, I let it sit again and went off.

Fishy part:

I come back to he phone, and would normally just pull down notification taskbar, and hit clear all notifications, since it said a bunch of things had sucessfully installed, but I notcied it also said "System update complete." Hmmm, I didn't start any system update...did it do it automatically? It had to of. I went to check for an OTA (HTC software update) and it found "System upgrade 1.47.651.1 (30.15 MB) - FOTA update." I canceled it since I pretty sure doing an OTA update on a rooted ROM is a no-no.

So what the heck is the problem here, I never had these issues before until I went back to the stock sprint ROM. I've already updated PRL a few times, does nothing.

Should I go back and reflash it and this time make sure it doesnt do a system upgrade until I've turned S-OFF back to S-ON? Once the phone is S-ON is it safe to update OTA?
