Re: How do i downgrade from helmi 6.1 to stock sprint
 

You really don't need to revert. I had a 1.04 too and these last one is v2.05 v2.05 has a smaller rom size. But I've still been able to add the same apps I used in v1.04 with no problems.

Re: How do i downgrade from helmi 6.1 to stock sprint
 

I have been testing many different versions of 6.1, but just now needed to try stock again.

Bootloader 1.00

Found an old file on my PC, APAC_SPCS_20600_300_11200_ship.exe.
Put phone in bootloader more, ran the file, done. Back to Sprint original.

10 minutes later found this file on my PC: APA_SPCS_20600_303_12700_WWE_Ship.exe, and just ran the exe without going into bootloader mode.

Both methods worked great. Nothing special or hard to do.
I think I downloaded both files directly from Spints website under software or programs for my phone.

Looking at other posts, I guess this works with 1.00/1.02/2.02 bootloaders?
