I have a Micromax Canvas Juice A177. Because it has a very small internal memory, I tried to swap the external SD with internal SD.
What I did
I rooted my phone and then I installed ES File Explorer, then I edited the
/etc/vold.fstab file and replaced sdcard0 with sdcard1 and sdcard1 with sdcard0. Then I reboot my phone .
I checked the storage and my phone storage was changed to SD card but total memory was still 700mb (as it was before). I then edited the vold.fstab file once again.
After that, when I checked the storage it showed as:
PHONE STORAGE ________________ SD CARD ________________ Mount SD card Insert an SD card for mounting
I had my SD card inserted, but it still said "Insert an SD card for mounting". When I opened the File Manager it was showing an empty folder (no phone storage, no SD card). Then I performed a factory reset.
The situation now
Phone Storage is showing the same thing (file manager as well). All the installed apps are deleted ,only the system apps are present with SuperSU. I don't have phone storage (only internal storage) and the external SD card is not working.
When I connected my phone to my PC using a USB cable, it is not showing the phone memory.
As you can see I have probably destroyed my phone, and I may not get any benefit from the warranty because I've rooted it. Is there any possible way to get my phone back to its previous state? I tried some tips from the Internet to connect via USB debugging with the Android SDK but it didn't work.
