What has been done to this phone and how can I fix?

[cfclay]

I bought a sprint device used after putting in my cricket SIM and it worked fine. After buying it I noticed that it didn't pass the financial eligibility check. Device works well except for the securitylogagent prompts to restart and it won't except updates to firmware.

I've tried flashing unlocked firmware with Odin and it fails. I also can't get the phone to work with cricket visual voicemail.

I don't know what someone has done with this phone. It doesn't appear rooted, but how does one get it unlocked for other sim cards if there's a financial obligation with Sprint....and how can I "fix" the firmware?

Have you tried talking to Sprint about it? If someone refused to pay off the phone, that typically leads to the IMEI becoming blacklisted (even though your checker says that it does not appear to be blacklisted). Due to the circumstances that typically lead to blacklisting, we discourage discussions about how to bypass it.
