Flashing roms via TWRP

[jreink01]

I know this should be directed to the twrp forums but I wanted to get feedback from owners of the sprint lg g3 preferably using the CM12.1 android version 5.1.
I have always had this issue where I am unable to flash roms on my external sd card via twrp. Everytime I try (just tried again tonight), after over and hour of restoring, it was only at 10%. When I flash the same rom on the internal sd (memory) it only takes about 10 minutes to accomplish the entire restore, its the same way for backups too. I don't understand why I am unable to do backups and restores from my external sd. It is very inconvienant to keep moving the backups from external to internal and vice versa. Plus, I can never put more than 1 backup on my internal because they take up so much space (roughly 8gb). It doesn't matter what backup rom I flash it does the same thing. Has anyone else been able to flash roms from their external sd card and if so, what did you have to do to get it to work? I have sent my concerns to the twrp team with no replies back. I am just curious if others are having the same problem or if their has been a fix for this.
I am currently on version 2.8.5 of twrp.

Does anyone have any suggestions or feedback on this issue? Thanks

Hey mate,
You could try installing the TWRP version for the G3 from their app, rather than just the generic version for any phone. If that doesn't work, then it sounds like your SD Card could be corrupted. I backup my whole phone to my external SD Card before I flash any updates or anything else, and can install the ROM updates from my SD Card with no problems whatsoever.
All I can really think of is either a new SD Card, or the official TWRP for the G3 from their app.

Thanks for the response. Do you have a G3 also? I have installed the official bumped version of twrp for my sprint phone and am still having issues. Just by curiousity, when you are in twrp, are you able to backup and restore directly to/from the sd card. I do not have any issues with my card other than this, I can transfer and move files, etc. I have noticed though on my 64 gb scandisk card that when it first boots up, it will say not able to retrieve location. I put a different card in the phone and that message stopped which makes me believe it has something to do with the card. That location message just started about a month or two ago.

It turns out that it was something to do with the external SD card. I replaced it with a brand new card and i am able to backup and restore to/from the external card with twrp.
