Mistakenly Pull off a part :(

that's a surfacemount resistor it helps regulate voltage and current flow its probably for the USB/Wifi chip judging by its
size I advise attempting to replace or repair it if its functional if you short it out you are liable to kill it
there should be a number on the top of the part along with the color should tell you what the resistor was rated forcurrent devices(rockchip sucks)

Yeah, good luck soldering back a surfacemount component - so tiny. Everything may still appear to work OK but that resistor is there for a reason. If you can find out the resistance it may be possible to replace it with a conventional resistor, I guess (bigger and easier to handle), but it's still going to be a fiddly job.

You have two choices.
Either you can take to a electronics / tv repair shop. Call them ahead of time tell them you only need a surface mount resister soldered. And they may only charge you a few lira's if you are lucky.
The other choice you will need a variable power soldiering iron. Here is one on amazon.
Yes you will need one. But you can do it with a regular one also. Apply to much heat and it will burn the pc board. And it will ruin your device. What I do if I absolutely don't have one. Is wait until the regular soldiering iron starts melting the soldier on the board and then unplug the soldering iron. Do what I need to do quickly. If it cools off to fast I plug it back in rinse and repeat. Be vary careful you may cause a cold soldering joint. Plenty of videos on youtube or else where to learn how to soldier correctly.
It's imperative that it must be replaced.
To add to Legitsu statement.
A small thought of what a resister is: Think of kinking a garden hose. The kink "resists" the flow of water.
And if that "garden hose" isn't there. It will put a lot of voltage/current across the rest of that circuit. Or worse cut that circuit off completly. Which is something you don't want.

if he contiunes to run it might very well burn up you are right at that point but given his slicon and superglue job there I question his ablitycurrent devices(rockchip sucks)

Shield your eyes and nose and make sure you don't breath that stuff in. Or you will be hurting for days.
Am I the only one who never heard of Cyanoacrylate?
Also I could of sworn heat sinks came with a clip for a reason
Another factor. They should only be used with semiconductors.
Come on guys you can hack saw those heat sinks to fit and cut your clip and soldier it to a earth ground like you are suppose to.

Wow... no offense to the OP but you do not use silicon to apply heatsinks! Silicon is a isolator not a conductor of heat! You probably made your cooling worse.
As for surface mount repair. It can be done by hand but not with a 2x4 sized soldering iron!
You have to get the correct equipment!
Temp controlled small tipped soldering iron (not cheap).
Proper tools to hold the part in place and proper solder.
Steady hands and a good desk magnifying glass.

you can't not simply install heatsinks with paste and glue you won't ever get enough pressure on them to be effective and whats worse you will end up with airpocketscurrent devices(rockchip sucks)

Yup, silicone was just there for sticking heatsinks to chip. But didnt work because heat too much and its melted the silicone. between the chip and heatsinks, there was thermal paste. But i have take all away and cleaned up the chips and heatsinks.
First i will give it to our technical department tomorrow, they will re-solder the resistor back, and i will stick heatsinks with thermal band to the chips;

its working but i need to find thermal bands to buy urgently!
