The ROM zip files... jesus there been so many. I've downloaded over 9 of them none of the work. Mine is AT&T by the way not sprint.
ok here are the resuts:
(bootloader) version-bootloader: 1.56.0000
(bootloader) version-main: 4.18.502.7
(bootloader) version-misc: PVT SHIP S-ON
(bootloader) product: m7_ul
(bootloader) platform: HBOOT-8064
(bootloader) modelid: PN0712000
(bootloader) cidnum: CWS__001
(bootloader) battery-status: low
finished. total time: 0.044s
That would be the RUU for you (based on MID and CID), though better check with @clsA, cause some of these newer RUUs don't always work.... and he's tried this one I think.
Oh and charge your battery before trying to run/flash ruu's!!!
