I tried playing 22GB Full HD video straight from HDD. No problem. I normally transfer large files through pen drive. ROM too, sometimes. Since TWRP can straight flash from OTG.
I don't see how USB OTG can solve your issue, I mean to install game. OTG helped me by letting me to do nandroid straight to pen drive and let me keep some ROM to flash in pen drive. I do keep Titanium Backup file to my pen drive once in a while. What else? Hmm...

Unless you sort of like mapping your OTG in USB Storage to local directory then possibly will work. I know ppl do this for lower internal memory phone to map external SD and use as internal SD so that all data can be stored on that SD card even though it's external SD.

No TiBa? Or at least do a nandroid backup before you flash a new rom. 

Did you flash a custom kernel?

Done back apps only...I give on PA cause of sudden freeze dan crash.

Now on slim bean...this rom don't have pie sad. Can this rom hode the navigation bar?

slim bean got pie.....its called slimPIE in interface setting

u can hide both nav bar and status bar

hello...im new with this flashing of custom rom...wanna know when need to do factory reset,wipe cache partition or dalvik cache...tq for ur help

actually u should factory wipe whenever u flash a new rom...to avoid problems

however,

if u are changing to diff rom, its highly recommended to factory wipe

if u are upgrading rom version then, u can wipe cache and dalvik only , don nid to factory wipe

owh ok...how about when flash kernel or mod..

for kernel u don have to wipe anything, just flash them

mod im not really sure, i believe u can flash over it just like kernel

Cant find any rom name by codex

Slimbean icon is to damn small.

my liquid smooth cant boot with Lean kernel . no idea why .
previously on AK kernel , can update to Latest SKL ver. but once i flash with lean kernel , it will stuck at google image.

i don think malaysia got it yet.....but if u cant wait u can replace the play store .apk urself 

if you are from AK kernel to diff kernel, you need to flash to stock kernel. the stock kernel flash zip is available at AK first post.

even i flash stock kernel ( AK first post) ,

then flash lean, i cant even boot, stuck at google word.

Only happened with lean kernel? Are you sure you're not flashing the 4.1.x kernel?

If confirmed 4.2.x lean kernel, was it experimental build or stable?
