Solution to Verizon LTE outage across the US on HTC Thunderbolt 4G
[Photos, Price & Specs] Samsung Officially announces Galaxy Note 5 with 4GB RAM and ultra-sleek body
Droidman at HTC Thunderbolt Forum has figured out a way to get around the LTE 4G outage currently experiencing with all the verizon wireless customers.
Yep. Down here in N. California. 1X only. Here is a tip - if you didn't know, Thunderbolt uses a "special" 3G, so during the outage, you may also lose 3G coverage. Here's how you can get it back.
1. Dial ##778# and press call/send
2. Choose Edit Mode. Password is 000000
3. Go to Modem Settings
4. Select Rev A.
5. Select Enable
6. Press Menu -> Commit Modifications
7. Reboot (will auto reboot after 10 seconds if nothing done)
Your phone will use Rev A 3G, but will switch back to 4G when available.
It seems to work for me...
**I am checking to see if you have to do anything to "undo" this when the network is back up and will keep you posted on what I find**
