So I'm obviously doing something wrong. I want to root my Droid and install Froyo, however, I only have access to a Linux box (or I'm too lazy to set up a VM for windows.) I'm trying to follow the various myriad of instructions at: http://androidforums.com/all-things...oot-related-currently-under-construction.html And I'm trying to use sbf_flash from: OPTICALDELUSION: sbf_flash However, when I put my Droid into the Bootloader mode. sbf_flash bombs out: Code (Text): ./sbf_flash VZW_A855_ESD56_QSC6085BP_C_01.3E.01P_SW_UPDATE_03.sbf SBF FLASH 0.01 (mbm) === VZW_A855_ESD56_QSC6085BP_C_01.3E.01P_SW_UPDATE_03.sbf === 00: RDL03 0x80500000-0x8054CFFF 62D6 AP 01: RDL01 0x00150000-0x001FFFFF 88CB BP 02: CG03 0x00000000-0x008C25BF 1CC1 BP 03: CG31 0xC0160000-0xC01637FF F15F AP 04: CG34 0xC0340000-0xC03437FF 8F6F AP 05: CG35 0xC0680000-0xC08E37FF A393 AP 06: CG37 0xDFF3C000-0xDFF3D07F 5581 AP 07: CG39 0xD0EF4000-0xD817F97F 537D AP 08: CG42 0xC0580000-0xC05BFFFF 73E3 AP 09: CG47 0xC0A00000-0xC0CA0FFF 5BFF AP Droid found. FAILED: could not claim interface 0: Operation not permitted So is that just a problem with the sbf_flash, or do I need to set something differently with my phone. I have 2C.6C version of the Bootloader. Running Android 2.1, stock from Verizon. Of course, if I try to upgrade, I get the message: Code (Text): E: Can't open /cache/recovery/command -- Install from sdcard... Finding update package... Opening update package... Verifying update packing... E:E0CD marker occurs after start of E0CD E:signature verification failed Installation aborted. Any suggestions?
