Broken resistors after power chip replacement

Hi, I made a big mistake. My iPhone 4s wont charge. The problem is the power ic. So I decided to replace it with my hot air station. It was not easy so I destroyed the faulty chip and some resistors. They broke off.

I solderd the the new power chip successfully but I can't solder the resistors with my hot air station because the wont hold and blow off, even on the lowest air level.

Here is a picture from the problem

So how can I fix the broken resistors?

Iceberg, looks like you ran into a bit of a mess. Interestingly enough, not a single resistor missing ;-) Anyhow the parts are as follows:

L28 2.2UH-1.8A-155MOHM VLS252012 fixed inductor

C605 22UF 6.3V 20& capacitor in a 603 package

C606 22UF 6.3V 20& capacitor in a 603 package

C206 1UF 6.3V 10% capacitor in a 402 package

C85 0.01UF 6.3V 10% capacitor in a 01005 package

C253 10UF 6.3V 20& capacitor in a 402 package

C282 4.7UF 6.3V 20& capacitor in a 402 package

C205 0.1UF 6.3V 10% capacitor in a 201 package

As you probably found out, replacing those is not going to be easy.

Thanks for your help. It seems to be impossible and too expensive for me. :(
