F30 FEM broken pcb pad when desoldering 95128

[HeXeN]

Hi, I have broken 2 pads when desoldering eeprom 95128 FEM 2013 F30 USA 315mhz, automatic 8HP.
I will try to find connecting point on the other side of pcb but I dont think it will help. At now car cant see FEM anymore.
Is there any chance to exchange for used FEM? I have good FEM from F20 EU 868mhz, without key, different SWFL.
I have read ori FEM coding & ee with VVDI2. Can VVDI2 exchange FEM for used one?
What is the best option?
I have also BMW Explorer (clone)
Do I need also ISTA to complete procedure?

When I program f20 donor fem with eeprom from F30 ori fem, then I can see it has changed to 315mhz.
I can read ISN from ECU, and renew keys, I have also new keys.
But dont know if I can complete all procedures with my tools. I have old ista, long time didnt use.

i think that you must buy fem with workink key.change vin in fem and sync ecm

If you can trace the track can be repaired

Looks like serial data output pin 2 important one and write protect pads missing? can you clean the whole by pin 2 to expose little copper or has it been ripped off?

Any tool can read this chip in circuit ?
using clamp ?

Temporary repair. Car alive. Key added.
I had to change new eeprom because old I think is broken.

Read with clamp with VVDIprog. Clean legs.

Whilst you can, melt down a candle, mix with a handful of DK THANKS, then pour
the wax and thanks on that wire, let it cool, can be removed if needed

I will swap FEM, when I get used one with key.

yes on YouTube work fine ! in real life ?

without issues if you work carefully. I read memory 5 times and check.
I will never desolder this chip again. more risky than reading in circuit. (too much glue resin etc)

What is the procedure when you have the donor fem with key?

There is option in VVDI2 FEM BDC exchange. Didnt try.
