Last weekend, my bionic, which is currently rooted running 5.5893 stock died after completely coming to a full charge. Out of no where , the phone went off and never came back to life. I tried everything possible to get it to power up. To no avail, I called Verizon and they shipped a new bionic to me next day. I'm faced with not being able to unroot my phone before I return it. I got the new phone, which came with the update 902 installed on it. My battery went into the new phone and was working fine. I was wondering, if I send this rooted phone back for the new one they had sent me, will I receive credit? Or should I take the battery out of my new bionic and try to power up the the rooted phone, only to unroot it for return. Please advise on what would be the nest thing to do. These bionic phones are not made consistently and this is my second replacement. Thanks for any help.
