I have an LG Optimus F3, rooted but no CWM, prepaid through T-mobile and I am currently looping at the Tmobile 4g LTE screen. I unknowingly changed my framework file to framework1 and the phone instantly became a paperweight. I should've known that this would cause a major problem. I have gone through dozens of forums and tried countless of tactics to resolve this issue. I have used lg support tool, adb, factory reset, and even attempting to install metro-pcs firmware onto this phone due to reading that they are similar, and also out of the fact that I've been stuck with this issue for days now and that the kdz for t-mobile phone was not able to be downloaded. The lg support tool stops at the downloading with no progress shown, the adb doesn't recognize my phone, factory reset attempts and then after 5 seconds or so starts the bootloop process all over again. To no avail have I seen anything working in my favor and I am needing this phone for multiple reasons. I thank anyone for helping and would love to donate a few dollars to anyone who gives me a working answer. Thanks in advance.
