    I just got my replacement Evo, preloaded with 1.47 (thankfully not Froyo). Is there a way to get to rooted 1.47 and then rooted Froyo without doing nand unlock? It was possible with the 1.32 roms I think, but I can't a root approach for 1.47 that does not rely on loading the eng-PC36IMG that overwrites the PRI. If it's not possible, I'll dive in with SimpleRoot, but I wanted to try this experiment.

    Thanks!

    all of the current root methods work by downgrading you to 1.32. but you need nand unlock it will save alot of headache if a rom goes bad

    Maybe I'm not reading the instructions correctly, but it seemed like all the 1.47 root techniques involved flashing the eng PC36IMG that loads the eng. bootloader, but also comes along with the rcdata payload that rolls back the PRI. I do not know if the PRI matters for sure, but I wanted to do speed comparisons with my old phone that was the 1.34 PRI. Can you point me to a root method that loads 1.32 without the eng bootloader?

    Thanks!

    If you unrevoke3 and then simpleroot, you preserve the PRI at 1.4. I read this on xda forums recently, but dunno if it applies to the 1-click simpleroot or the 4-click.

    Any idea which thread that might be in? I thought all SimpleRoot approaches pushed the engineering PC36IMG.zip to sd card and flashed it, which would be the only thing you cannot do and keep PRI 1.40. Perhaps I misunderstood what SimpleRoot did, but I thought it fully unlocked nand, which can only be done now with that update from toast's part 2 (if my research is correct, although I wouldn't be willing to bet on it).

    Thanks for the link. I did more research on risks/limitations of not fully rooting. There were too many posts about issues when nand wasn't unlocked, so I just did the full root again and dropped the PRI to 1.34. I'm assuming there will be a fix at some point, and if not, I'd still rather ensure I can always root my phone down the road.

    I think this is a good choice. xda devs are working on an isolated zip for PRI update, so at some point, all of us at 1.3.x can just flash a zip and get the updated one.
