V10 causes infinite power cycles

First time poster needing help.  I updated to V10 a couple of weeks ago.  Everything was fine.  I sent a mass text on Saturday and the phone went haywire.  It power cycled every 30 secs to 1 min.  Phone was unusable.  Took it to Verizon yesterday.  They noticed the problem and gave me a new one.  That phone started flickering while they were setting it up.  They gave me yet another one.  (With V10)  It was working great for a couple of hours until I sent another mass text letting family know my phone worked again.  Phone started power cycling every 30 secs to 1 min. again.  Unusable.  Putting it in Airplane mode stopped the power cycling.  I called Verizon.  They have no clue.  Sending me another phone and they hoped it would not have V10 on it.  They couldn't guarantee anything.  Does anyone know of a fix?  Can I revert to V9?  If so, how?  Thanks! 

I can't find a way to revert to V9.  Maybe the phone they send me will be V9.  I should get it tomorrow. 

I downloaded the update last week.  Within a couple of days my phone began rebooting almost constantly.  I had to take the battery out to stop it.  I was about to decide my phone was history.  Then I thought I'd take the memory card out and try it.  I left it turned off for several minutes.  Without my memory card, I have been using my phone for three days with no problems at all.  It makes me wonder if the update has caused my card to be incompatible with my phone.  I just hope my phone keeps working.  It's the best phone I've ever had.  Before the update I had version 9.  On that version my phone only rebooted occasionally when I turned on Bluetooth mode.

Same thing happened to me.  I updated OTA to V10 and within a few days my phone was power-cycling every 30 seconds.  I called Verizon and was sent a replacement the next day with V09.  No problems with the new one... and will not be updating to V10 now that I see I wasn't the only one experiencing this problem after the update.

After a week of V10, I to noticed the power cycling this morning.  Very annoying.  After reading a few different forums it was not hard to figure out that the phone was trying to get some kind of info for in Airplane mode all was fine.  Tried the trick of switching to nam2 and let it program and reboot.  Switch back to nam1, *228 to program and reboot and no more power cycling. 

You have to be quick while doing this so the annoying reboot does not stop you in mid stream.  If it does it will not do anything to the phone, so no worries there.  Power up the phone and quickly head to Settings and Tools, then to Phone Settings and at the bottom hit NAM select and select NAM 2.  Once your in NAM2 the phone will not power down.  It should also dial *228 on its own to program.  If it does not then dial *228 and as soon as you hear the voice hit 1 for programming.  It will download the location of the towers around you and update the phone.  It will reboot for the changes to take affect.  Now the phone is using NAM2 and will not reboot on it's own, but you can not use your phone to send or receive.  Now go back into your settings and select NAM1 and quickly dial *228 and as soon as you have connected(you hear the voice)hit 1 to reprogram.  Reboot and you will be fine.  I have sent and received txt,vid, and voice msg.'s, watched Start Trek on Vcast, surfed NFL and the Web with no issues since I have done this trick.
Let me know how you make out.

I did the nam2 reboot trick last night to stop the power cycles. My phone has just gone into a power cycle frenzy turning off/on every 60 seconds. I hope LG/Verizon is working on solving this V10 problem.

CptTom: I was able to get back to Nam1 and it worked ok for a few hours. I even fell asleep with the internet vz home page on for 5 hours and it did not power cycle. Then about 20 minutes later it went into a power cycle every 30 seconds.  it would cycle stay on for 30 seconds and cycle again. It eventually stopped clcling after 20 minutes and I put it in airplane mode. It has not done it since.
