I have an RCT6773W22 that bricked about two years ago. In that time I have searched, in vain, for a way to bring it back to life. That is, until this month, when I found this forum: https://forum.xda-developers.com/general/general/stock-rom-twrp-root-oc-uv-rca-7-voyager-t3087075 In it, it detailed how to reflash the firmware for v31 and v38 (I had a v28 and if you read other posts in this thread, it is almost identical to v31). I successfully completed the process and my tablet was finally fixed... for about fifteen minutes. It then slowed down to the point of freezing, at which point I promptly restarted the tablet. It started up and froze on the splash screen. I started it into TWRP and upon restarting from there was met with a message saying no OS was installed. In short, what do I do to fix this, if anything?
