Here i mention it
So read it carefully before trying it in our 504q
Better to try any rom with full root permission and select 1st your defalt memory to phone memory
Meteos is android app
Take cwm backup of your current rooted rom
then install meteos app then select.. How many memory u want for app
Like 1.5, 2, 2.5 gb..
Only select that size which is less than your (internal memory+app memory)
Like my app memory is 1 gb and internal 1.5 gb, then i selected 2gb for app. .
After select this app ask for reboot in recovery. Select that..
And now in recovery restore your cwm backup of rom.. Which is created in step 1.
Caution - after partition like that.. U can not install stock rom without sp flash tool..
But all custom rom will work.. So no worries.
Meteos app link
1 more thing.. After this.. First if it will not show u internal memory.. Then just flash any custom rom and all will be fine..
And for installation of stock rom u need firmware flash by sp flash tool
