Where to get individual chips?

Hello there, ever since I got Galaxy 10+ I wanted FM Radio inside (Snapdragon had it, S9 had it, so why can't I have it...)

I have the SM-G975F (International varsion) of the model which has Exynos chipset

and when I asked around (XDA forums) people told me, no not possible, hardware not there, Exynos models don't have this, but nobody told what was missing, so years went by and I never forgot about it, and always searched the internet thinking, well if S9 had it, why can't S10 maybe it was just software locked

Well, one month ago I discovered a forum post where someone casualy mentioned that Korean Galaxy has it (SM-G975N)

I was like, what, thats great, so try to activate it

Well after learning about how this was included, which libraries I need in software, etc (my phone is rooted so modding the software was always easier for me then modding the hardware)

I compared the service manuals between SM-G975F and SM-G975F) (which are here: https://www.mediafire.com/file/cpispk4zj...

You can find this on page 117 on korean manual where block diagram is

and discovered that this liitle tiny chip: RTC6213N: https://www.richwave.com.tw/en/page_prd_...

is missing on mine

Well I discovered that on the service manual, I did not open my phone to check that

So if I add this as well as some pasive components to their respected places and make nessesery software changes, then radio should work

So here are all the chips I need to add FM Radio as well as TV to my phone (yes if I have my phone open and add stuff, might as well add DTMB tuner even if there is no signal in my country)

L = Inductor

C = Capacitor

R = Resistor

O = Crystal Oscilator

*

*= Also uvailable on SM-G75F (and maybe some other models (its used for other things, its not on the same spot but you could still a component from there (if you found a donor board of course)

**= DTMB as well as FM Radio both use this part

***= Also uvailable on SM-G75F (and maybe some other models) + DTMB as well as FM Radio both use this part

Now I have 4 questions

#

I am in Europe (in Slovenia to be exact), so whats the best store to buy this parts (6€ for a stupid cerammic capacitor seams like a ripoff (it should be 2€ no more (at least this is usualy how much smd capacitors cost) and even worse, how can I prevent from receiving fake parts

1. Do pasive components need to be from samsung (a lot of stores sell capacitors, resistors, inductors, etc)

# How hard is this to solder, I have nor tools, nor eyesight (my eyes are very bad) to solder SMD, so I thouhght I would pay someone to do that for me when replacing phones battery (when the phone is already opened anyway), not sure if battery replacment shops have soldering equipment, I hope they do

1. Dooes samsung change PCB payout between their korean and international version (like I hope that traces are intact, because whats the point of soldering chips, if you find out that traces don't connect i2c and SPI signal to the required chips at the end (on the board there are gold spots, where chips should be so I hope that traces are still uvailable even if no chips are soldered)

I know this idea is crazy, but I realy would like to get a radio on to this phone

and I know that the phone is old and I will be forced to upgrade soon anyway (forced updates, apps to bloated so hardware cannot keep up, blah, blah, you know how this works), but I would at least like to enjoy FM radio on this phone, even if only for 1 or 2 more years

I also thought that maybe its just easier to get the korean model (SM-G975N) instead (since I only need one SIM card anyway) and put Slovenian firmware on it, but I cannot get it in green (even if I found some on ebay) and because of stupid bootloader preventing downgrading, finding one that on top of being green, that also runs Android 10 (because you know how most people are, they will update as soon as possible, not caring if updates will remove something they like or slow down the phone) is probably next to impossible

So yea, I hope some of you repair geniuses would be able to anwser my questions (I was always better at modding software then hardware)

If only this stupid chips would be there, this task of adding something (that in my oppinion should be uvailable on every phone) would not be so hard
