Ut Oh- I used Ut Oh

Some of you may have seen my post on upgrading from M9 to G4.

In that post I had said it appears that it was more of a Sprint issue than a phone issue. But I was keeping the G4 for other reasons.

Any way I had the M9 on swappa and prices seem to be tanking. I was offered 5 ugh.

Then I spoke to my wife and convinced her that she might be better off with the M9 than the M8 and she should at least try it.
Screaming bloody murder she agreed. The very first call went straight to voice mail as she drove away with her friend and I could still see her in the drive-way.
I would sell her reliable S-Off HK M8 if she was ok with M9.

When she got back I forgot that I left it in Auto (i.e. Global mode which includes GSM). I've seen phones misbehave when set that way.
I set it for LTE/CDMA. I suspect if I put the phone in CDMA mode it would be ok. But neither M8 or G4 needs that.
I have seen G4 do this once in a VERY weak single which is why I thought M9 was ok. But the M9 does this a LOT.

Ran the latest RUU on it that just came out which does have new firmware. And I only rerooted it via TWRP (nothing else), pure stock otherwise.
By the way Wifi Tether Router now works and only requires root, nice.

Anyways she drives off to go shopping. Still on the street I call her, didn't even ring once and went straight to voice mail (like the phone was off). Called 30 min later, rang forever and didn't even go to voice mail. Later I finally did reach her.

So now I feel guilty even selling it for any price. I really don't want to deal with Sprint on a phone I don't even want anymore.

I thought about making a "claim" on TEP and just couldn't do it.

So I figured why not try Ut-Oh. It does cover "damaged" phones. I told them exactly what was wrong and they refused to do ut-oh.
I told them I'll go drop in the toilet and be right back.

So I call them back with the toilet episode and they accepted it, so sad I had to do that, I tried the right way.

So I have not dropped it in the toilet. I really rather not. I hate seeing waste. I asked if the phone suddenly "recovered" in shipping when they got it back, what happens?
It can happen on dunked phones when they dry out.
They said I would still keep the replacement.

They said it will be a remanufactured phone.

Should I dunk it? It is S-Off, which is partly why I didn't want to go to sprint. I think you can hide it with hacked hboot, but I was not sure how fully hidden it was.

So should I dunk it and save headaches and feel guilty or just send it and they won't care. They will also see it's S-off too and they might take notice.
I prepaid to get new phone quick and just have to send old one back to not get charged.

Not sure if I should even try the new M9 with my wife again or leave it sealed and sell it.
