wait a minute....tweaking 33?? im at 27 now on my e367, should i go for 33?

will do! 
wont spoil the modem yeah? and this tweak got endorsement from blacktubi yeah? coz warranty still long from him...hehehehe 
ah.....now it seemed like mf680 is a lot superior from e367.....last time when i bought e367, blacktubi running out of stock after i make payment, so offer to change to mf680 without extra charge but i tolak....now all out blaming myself for not taking the offer   

my zte mf680 tweaked to 33tx + panel antenna

working amazing though

i just tried this evening, so still in trial mode.
if u wanna try too, change this value NV_WCDMA_VGA_GAIN_OFFSET_1
my default value is -78

tested device e367
slowly change the value till u find optimum value, and dont go overboard as we dont know what will happen if value is overlimit..
different device will have differ value..
and 1 more thing, signal is not everything, but position does matter   
report your finding here         
and i not responsible if anything happen to ur modem   

E372 default is -2xx , but i try -3xx , much better signal

is 15Mbps = 1MBps ?

if not anything wrong with my dashboard ?

its a E372

Thanks, bro. 

I'm gonna kill my E372 anytime with -444 value. 

For the meantime, I don't need LTE because the speed is like graveyard shift and web surfing is F awesome.
