Don't Upgrade to OF1 If You'd Like To Root/Downgrade

[trailblazer101]

It has been confirmed that updating to OF1 includes the downgrade protection we've seen in the T-Mobile builds on 5.1.1... You won't be able to root directly on this build, either, since the exploit was patched by this ROMs build date. I will make a package that will allow users on OE2 to to update to OF1 while maintaining root. If you are on OC3 still you can upgrade to OE2 using my tutorial in Android Development.


Can someone who updated to OF1 successfully please try downgrading back to OC3 using the ODIN image provided within this General Thread? Since no one else has released a OF1 ROM/ODIN package I was going to do it myself, but along the way I noticed a change within this update package-- it now includes a magic string header at the very end of the update process, just like the Lollipop 5.1.1 ROMS for other devices that now incorporate protections against downgrading. I'd rather not bone myself/everyone else out of future development if this mechanism is in fact in place.

Thanks in advance! As soon as I have a confirmation it is still downgradable, I will finish this package.

Odin will not downgrade after OF1. I've tried 5 times using 2 different PCs and Odin failed every time.

I like your avatar xD lol.

And thank you for the confirmation. I was hoping that wasn't the case, but it was leaning in that direction... I'm hoping you didn't update just for this, I'd feel rather bad... I'll change the thread title to reflect this.

why not go ?

Because you lose root

And you will be unable to flash any previously issued versions.

Looking like no 5.1.1 with root??? ... guess I'm staying with the stock build when I first got my phone and rooted it.

Why do you say this? Is there a reason why you believe if I have root now I won't be able to flash a developer's modified 5.1.1 once it arrives?

Had a few "?'s" on that statement. Purely assumption on my part, so take my previous statement and my next few statements with a grain of salt. Ping Pong root has been patched and unless they find another method there is no root on 5.1.1. Locked Bootloader, with no way around that, so no custom kernel to root (a la this method). Right now in order to upgrade to OE2, you have to use a patched version that keeps root, what happens when it can no longer be "patched" to keep root in further builds? If you've upgraded already to the latest build via OTA, you can no longer downgrade. Trust me, I want to continue to have root for what ever the latest build is out there but Verizon/Samsung have been locking things down tighter and tighter and there is always the possibility that an exploit isn't found and end up with no root on later builds than what we have now. Again, all of this is just my assumption and I hope to end up wrong in the end about everything, 5.1.1 isn't even out yet for us so we'll see when it drops.

I know this is probably not the right place to post this but i would be willing to donate a 100 dollars to someone that gives me root on verizon s6 OF1. I messed up and upgraded. So I sure hope someone can get root. I have tried everything.
Thanks

I know this isn't exactly what you are asking but I'd swap my non-upgraded (OE2) Edge (128GB, Black) for $100! I haven't upgraded or rooted.

So I give you my phone plus 100. When did you buy your phone. Is it verizon. And what bugs does it have cause I have heard the edge has some problems.

Verizon. I've had it a month or so. No bugs. I only want to replace with the same or very similar phone though

These are the times when we wish there was an Undo button...

Is it possible to downgrade with Pit file and reformat the whole thing

Hi jpeps3,

Could you give more details about it, and - if there is - a link to a guide on how to do that?
Also, have you done that successfully?

no.. once updated you can no longer downgrade.. the pit file would not matter if you updated to of1
