Fastboot commands don't work, help?

[Daniel Thiberge]

I deleted download mode following a tutorial to fix boot. It booted up and now I get "Invalid Battery". I bought a new battery and replaced it, same error. I assume it something with the partitions. I have the correct image files but they won't flash and I can't use fastboot erase.

Screen right after fastboot boot:
[500] Fastboot mode started
[600] -- reset --
[610] -- portchange --
[710] fastboot: processing commands

fastboot erase aboot brings:
erasing 'aboot' ... on command prompt
and
[346290] fastboot: getvarartition-type:aboot
[346350] fastboot: erase:aboot

after those appear it just hangs like that

unplugging it after that command gives me:
FAILED (status read failed (Too many links))
finished. total time: 164.350s
on cmd
and
[514820] -- reset --
[514820] EP1/out FAIL nfo=40 p0=f90bao0
[514830] -- portchange --
[514840] usb_read(0) transaction failed
[514890] fastboot: oops!
[514940] fastboot: processing commands

trying to flash a partition has it tell me the file transferred but then it hangs

The computer definitely recognizes the LG G2 but all I can get into pre-boot is fastboot.

I think LG has a tool similar to Kies for Samsung. You might be able to reflash the whole ROM, with, I believe the booloader (download mode) included.

All I could find is something called LGtool which brings up an error when opened..
Edit: If you mean LG PC Suite, I don't think it has a repair function like that

Kind of a bump but I have an important update. ADB is working now.

Does anyone know how to flash/write partitions using ADB instead of fastboot?
I have all the img files and if I could just put them in place this would all work!
Of course, the phone is only on for about 30 seconds at a time, so I'd need to rush.

You might need to consider a JTAG service.

I can use ADB though, albeit for only a bit at a time. If I know the Windows commands for transferring over partitions from .img files through ADB then I think I can fix it myself.
