@gsm123 this board has definitely seen better days. Looks like all of your solder pads have been lost as well. Not sure what or why you would try to apply jumpers. If you needed to you could have connected the battery connector like this:
Anyhow, neither here nor there and time to move on. your board will have to have the solder pads repaired or you can try to run jumpers, just not the way you have done it in the past.
Lets start off with the missing parts:
FL7_RF Inductor 240-OHM-0.2A-0.8-OHM
C20_RF Capacitor 100PF 5% 25V CERM 201
C12_RF Capacitor 100PF 5% 25V CERM 201
FL5_RF Inductor 240-OHM-0.2A-0.8-OHM
C36_RF Capacitor 100PF 25V 5% 201 package
C11_RF Capacitor 27PF 25V 5% 201 package
FL5_RF and FL7_RF are for your NTC connection and the Gas Gauge connection respectively.
Let us know if you have the skills and tools to even attempt such a repair. I would think that if you need to have it fixed for whatever reason, contact @refectio on this forum and see what he thinks. His specialty is board level repair.

well i have some thin copper wire, soldering paste and a soldering iron.... can you make any recommendations on what i can do to get started or how to proceed? i really would just like to retreive the data on it at this point but its proving to be a bit diffcult since i cant get any power to it to turn it on.
Thanks,
also i was able to find this: please see youtube link https://www.youtube.com/watch?v=5zebHu7c... but its proving quite difficult to pursue with only a magnifying lens and not a microscope
Phil, if you're goal is to retrieve data, then you really only have one shot at repairing this, otherwise you will likely cause more more damage. The challenge here is that there is no simple way to jumper the filters because the vias were also destroyed. That connection then goes directly underneath to the PMU. So the only option is to remove the PMU and try to add the jumper there. This is not a trivial repair attempt and certainly not DIY.
aww really? do you think i could get away with any alternatives? like scrape were the 4 capacitors use to be and trying making a line with copper wiring or using a conductive epoxy?
@gsm123 you are already going down the wrong lane when you are suggesting using conductive epoxy. Conductive epoxy is not what you are needing. If you really need that data you cannot even think about some halbaked idea. You will need a proper soldering iron/station and definitely something better than a magnifying glass to get this done. Conductive epoxy is not what you are needing.

Congrats, you killed it. It is now beyond repair. That looks like the baseband EEPROM and if it is then there is 0% chance of it working again. Send it to a microsoldering place if it is for data recovery. If not, just get a new logic board.
