I read somewhere that iPhones are not covered by warranty if their bootloader was downgraded. I downgraded my bootloader with ziphone to BL 3.9. Is this true. Do they check bootloader compared to what it was manufactured with? I thought that as long as your iPhone was not opened and you restored to original software and revirginized you would be okay. Quick answer please.

Quick answer: I don't think anyone knows at this point. Bootloader downgrading is fairly new, and I doubt many phones have been returned to Apple since then.

The BL version isn't immediately available onscreen (as the main firmware and baseband firmware versions are) - Apple would need to plug into a PC/run special software to see BL version. Obviously, they have this capability - whether/not they use it is unknown.

If you're swapping out at an Apple store (vs sending into Apple for repair), I think you're more likely to get away with it (they are less likely to do 'deep' checking at a store than at the factory).

But, I think anyone who hasn't themselves tried a BL downgrade/return will only be speculating (as I am).

To be clear: virginizing/restoring your phone will NOT touch the BL - all other pieces (main firmware, baseband) can be restored to factory defaults via restore, but NOT the BL version.

I have a feeling that if this becomes a big enough issue, someone (Geohot?) will figure out how to upgrade a BL 3.9 to BL 4.6.

I know people (possibly including him) say it can't be done - but many things "couldn't be done" not that long ago, which now can be done.

If there's a need, I believe someone will find a way.

Just my opinion, of course.

Its has been done by geohot but not a software but hardware way. GeoHot said this in his own blog.

the answer is very simple: if you dont have an AT&T account, you dont have a warranty.

Thats not entirely true.

I unlocked this iPhone for a guy and he some how screwed it up so that the slide to unlock would not slide. The screen like lost its touch sensitivity.

This guy was using his phone on T-Mobile and he came to me a couple months after I unlocked it and said, can u fix it?

I restored it.. nothing happened.

He went to the apple store and they replaced it.

But unlucky for him at the time there was no OTB 1.1.2 Unlock.

I'm not worried about that, I have AT&T. I want to here an answer from someone who's done this. Incase you're wondering why I did this is because I travel a lot and I don't want to face international fees. And do they really keep records of your bootloader?????

haha i doubt it

dont worry dude.. why would they care if your bootloader is downgraded?

you have AT&T and you are paying them monthly.

they dont care if u have it unlocked or not

WHY the helel wold you want bootloader 4.6 when you have or have downgraded to 3.9. 3.9 is better dude

Some of us "normal" people have an aversion to anything we do that is permanent, aka, downgrading the BL.
