[One (M7) Q&A, Help & Troubleshooting] edegg:
I can't flash ruu, because of without command fastboot oem rebootRUU I can't do it, and this command not working - phone boots not in RUU mode. Maybe from sd-card with file PN07IMG.zip? But I found only one ruu for my model x.xx.500.x : PN07IMG_M7C_DWG_L50_SENSE60_MR_APTG_TW_7.17.500.9_Radio_1237.29.35.0903_CNV_CNV_APTG_4.23_0,

but bootloader says somethig like "wrong zip..."

I have no phone with me now and can't proceed fastboot getvar all. Instead of it I offer this, from my post on 4pda.ru:

C:\802>fastboot oem boot
