I'm a bit of a n00b at this, so please forgive me.
I started with Android 4.1.2, Kernel 3.4.0-g298631f-02047-gec59411, build 10.1.C.0.370.
I rooted it using Doomlord's easy-root and then when attempting to flash custom recovery, I accidentally flashed some other .img and the tablet wouldn't even turn on. I cried. Like, a few good tears.
Went online, found out I wasn't screwed, and figured out how to flash SGP312_10.4.B.0.577_VMo DE_1273-3719_WIFI312G.
But, as I said, I lost root, and am confused about how to downgrade back to 4.1.2 properly without bricking.
Here is my current info:
Version 4.3, Kernel 3.4.0-g1b44cd5, build 10.4.b.0.577
In this thread, under "Downgrade your rom" and "back to 4.1.2 and rooting" it says "if you're in 4.3, Flash this SGP 351 4.1.2 FTF using Flash Tool and it will be booted in 4.1.2. if you have different Variant downgrade to your Variant FTF file"
What is a variant FTF file? Can I just use any SGP 312 4.1.2 FTF? Does anyone know a safe one to use?
