For a 4.3 ROM, you need to install 4.3 bootloaders. Are there any drawbacks?

Tip us?

Default For a 4.3 ROM, you need to install 4.3 bootloaders. Are there any drawbacks?

I'm considering upgrading to a 4.3 rom from 4.1.2 and I've learned that a stock image of 4.3 must be flashed first (thorugh Odin?) to update the bootloader to 4.3.

Is there any drawback to upgrading? Will I still be able to flash 4.1.2 roms using the 4.3 bootloader? Will I be able to downgrade to the 4.1.2 bootloader (should the need arise)?



Side question: is Odin the only way to update the bootloader? Can it be flashed through TWRP?

You'll have Knox. (Stock) which locks u down cause u can't downgrade and by rooting, you're going for a un-reset-able Knox Warranty Void trigger. Downgrading bootloader is impossible as of now, but flashing ROMs should be possible. (Should, not damn sure)

Side Answer: don't think so. Just flash stock 4.3 through TWRP and u should be good to go.

I'm running 4.3 JediMasterX2 with old bootloader and devil kernel and everything seems to be running fine. There was a very informative post made recently they gave a clean and simple explication of pros and cons to bootloader update. I'll try to locate and post a link but long story short, it's in your best interest not to update bootloader if you don't have to.

Please don't do the official update and get yourself locked down like many of us have. I have flashed many 4.3 roms and they worked fine. Got a new phone and did the official update and now I cannot send this device in for warranty because of the KNOX flash counter.
