[Advice] BootNeuter for Dummies [read if n00b]

Some people say they have seen better battery life with 4.6, but there is no real proof. I say leave it on 3.6!

But my baseband is 04.04.05.G, and my BL is 3.9. Are these settings OK, and if there any advantage of going to BL 4.6 at all?

Thanks!

The settings are fine but no advantage of being on BL4.6.

But if your in UK and your BL is 4.6, your warranty will remain intact as the iPhone's can now be officialy activated through iTunes for any O2 sim, so no contract anymore. So if you got a problem with your iPhone you could get it repaired by Apple for free.
If your on BL3.9 your warranty wil be void unless you know how to get it back up to BL4.6.

If anyone knows how to get their bootloader back up to 4.6, any help would be appreciated. Thanks

If your phone is working fine. Don't mess around with the bootloader unless you know what you are doing.
You can really mess up your phone.

The bootloader change is needed only if you want to put it back like when it's out of the box for apple warranty stuff or you want to send back to apple.

There are 2 versions: 3.9 and 4.6 and that is based on the week of production.

Rule of thumb:
If phone was OTB <= 1.1.1 - you have a 3.9

If phone was OTB >=1.1.2 and less than 2.0 then you have a 4.6 ***

*** if the phone was unlocked using iliberty or iplus - the BL changed from 4.6 to 3.9FB
*** if the phone was unlocked using ziphone (bad bad bad) - the BL changed from 4.6 to 3.9FB
*** if the phone was unlocked using pwnage then you can end up with 3.9FB or 3.9neutered of 4.6neutered.

If phone is 3G, boot loader is 5.xx ? (you cannot mess around with BL on 3G)

The way to change BL version is to use bootneuter. Again, don't mess around if you don't know what you are doing. You've been warned !!

And lastly, if you really really screwed up by blindly messing around, you will end up with a 3.8 bootloader.

Changing 3.9 to 4.6 to get better battery life is a myth to me. I don't see any direct or overwhelming confirmation that it is so.

Some great advice here, cheers for posting.

Recently, BootNeuter got updated, here you have important information about its usage.

Important Information:

==> Do not close BootNeuter while flashing. Sometimes it takes longer
than expected, but that is just fine. If you close it or crash it, you will have serious
troubles.
==> Do not manipulate your iPhone while BootNeuter its working. Sometimes
errors happen and people press buttons accidentally.
==> Uninstall BootNeuter when you're done with it. Friends always take risks
without knowing what would happen, and when they realize what's going on, they
just close the application. There you have, a bricked iPhone.

Recommendations:

==> If you forgot to set autolock to never, and iPhone locks, turn on the screen
then you should see the progress, it is still working, you can keep it
alive by pressing the volume button or the silence/ring switch, do not crash the app and
do not try to close it. The app is still working.
==> BootNeuter is not a game, if you do something wrong, your iPhone will pay it.
==> If your iPhone is working fine, there is no need to use it.
==> (you say "You're trying to scare me, iPhone can't be permanently bricked") I say,
check the Software Unlock forum for a thread about the 1011 error. There are
some iPhones that are bricked and there is no solution for them.


If you need further help, don't mind about sending me a PM.


<------- Helps? Thumbs up please!

one question:
when i sue the Pwnage Tool 2.0.2 in Expert Mode, it asks if i want to allow upgrade of the BootNeuter (or BootLoader... sorry i don't have that laotop with me now)... so,

should i allow UPGRADE? FYI, i haven't done that in the past, but what would happen if i did? :hack:

@yehudah72,
According to your signature, you have an iphone 3G. Is this the phone you are working on?. Pwnage 2.0.2 + iphone 3G is for jailbreak + activation only. You will not be able to change Bootloader.

How can I tell what version of the bootloader my iPhone has as stock in case I want to revert to factory condition later?

iphone 2G ?? or 3G ?
if 2G, post your serial number (first 5-6 digit will do) then we can tell you.

It's a 2G. the serial is 7U729xxxxxxxxxxxx

3.9, right?

Does pwnage/bootneuter CHANGE the bootloader version or change the bootloader itself? I'm slightly confused.

week 29. Definitely 3.9 bootloader
Pwnage/bootneuter does not change the bootloader version unless you tell it to (during the custom image creation).
To have an unlock, bootneuter will need to neuter your Bootloader (this is a must).
Please look at the tutorial
