Repair 3.9 baseband before upgrading to 2.0.1?

[patenmac]

Hi All,

Forgive me, but I was unable to find an answer to my situation.

I have a 1st gen iphone, jailbroken and unlocked, running fine on GSM service outside USA (not ATT).

Modem Firmware 04.01.13_G
Bootloader version 3.9_M3S2
Version 1.1.1(3A109a)
I use a Mac, OSX 10.4.5

I want to upgrade to 2.0.1, jailbreak & unlock. The flowchart for upgrading to 1.1.4 indicates that I need to virginize the phone and repair the baseband before upgrading & unlocking 1.1.4. Is this still necessary? Or do I just use PwnageTool?

Thanks for any help!

You don't have to Virginize or repair
Just pwn your phone and make a custom 2.01 ipsw and restore to it
Hackthatphone.com has great tutorials on this

If you are talking about my flowchart on my site, I just put some more info at the very top to keep people from being confused about following it.

That flowchart was made waaaaaaaaaaaay back when people were getting those bad IMEIs on their phone from having corrupted basebands. The flowchart was designed to check known and unknown phones and how to correct them.

I haven't heard of anyone getting a bad IMEI on a firmware update because they had a corrupted baseband for like 6 months or more now.

If you, or anyone, is running 1.1.1 and all is well, chances are extremely high (99%) that you can safely update without needing that chart.

HackThatPhone,

Thanks for the help and great job on your site. The flowchart was very helpful. My ipone has worked fine on 1.1.1 so I ultimately decided to wait to upgrade to 2.0. Now that time has come and your upgrade guides are excellent. People like you make it possible for casual users like me to be more productive and try new things. Thanks to all!

One question, if I did get a bad IMEI due to the firmware update, is that repairable?

Thanks.

It should be repairable. I think bad IMEIs only occurred on 3.9 iPhones and not the 4.6s.
