Hi Serges. Thank you for the video. I got a question, my nintendo switch lite (which uses mobile components) has a very unstable wireless performance. The signal strength varies wildly, even though the handheld is sitting 30cm away from my router. It goes from 3 out of 4 bars down to just one when downloading a game or an update, and that's when it's connected to 5Ghz. When it's on 2.4Ghz, it sits on ONE bar, no matter how close the router is. I've checked my router, but signal strength is set to high and all other mobile devices on 2.4Ghz report very good signal strength, but the switch lite. What could be the source of the problem? EDIT: I purchased another set of cables (black & white) and I connected them to the board, problem still persists.

Hey, I was thinking about using an old cellphone as a 4g router for my car. Now for this to work properly it needs an external antenna connected to it that goes outside. On my phone's pcb there's a tiny coaxial connector connected to a tiny wire running down the right side of the chassis, but the actual antenna seems to be hidden in the backplate which has 5 metallic connectors all around it and when it was off, the phone didn't have a 4g connection. So my question is what is that wire for ? Is it actually the 4g antenna and could I replace it with a longer wire that goes through the roof of my car to get a good connection ?
If you listen to that video well you will hear me telling what will happen if a this ic or that 1 is bad So you know that faulty ic based on what the fault is
phone won't turn on. replaced the screen, battery, and charging port. What is usually the next culprit? It has to be something on the motherboard I'm thinking. Won't force reset either. Also what ic containers the saved data and is a chip off data recovery possible? Thanks
@@SergesMike I have heard that the data will be encrypted a chip-off data recovery is not possible with modern cell phones because the phone companies encryption.
First check imei and baseband Maybe, but u have some steps to go through before suspecting network ic. First check the network cable and the line if its not broken If okay try changing P. A ic if still not working then you can go now for the R.F which is the network ic if you change and it doesn't work then reball or change power ic
hi sir. can you help me. my phone screen has lines, is that can be fixed by replacing the screen unit? or other component is faulty which causing the problem??
I've an android 4g phone (realme x2) bt it's 3G or 4G signal doesn't work,,, it only shows 2G or E signal ... i mean if you chang it to 3G or 4G it wouldn't work... what kind of problem it is?? and which network ic is damaged?? reply please
First you need to know how those ic work so it will be easy for you to know that this ic or that 1 is faulty according to the problem with the phone since most mounted ic can't be tested with a multimeter It's easy to identify some power fault using a dc machine For example: when a phone comes to your with no sound the first thing you suspect is the speaker So now if a phone come to you with WiFi problem and you flash it and it still doesn't work them clearly its the WiFi ic. I will send u a video on how to identify faulty emmc and cpu
Sir. i love your teaching.So simple and understandable but i have a lot of questions to ask. i don’t know if i can get your whatsapp number or probably a platform where i can ask questions about mobile Ic... Thanks 🙏

That's actually 3 and 4gb cable network.
If you instent it as you are saying it will work just fine.

phone won't turn on. replaced the screen, battery, and charging port. What is usually the next culprit? It has to be something on the motherboard I'm thinking. Won't force reset either. Also what ic containers the saved data and is a chip off data recovery possible? Thanks
The ic that contains save data is the emmc and you can recover the data using any reprogramming box like JTAG or UFI BOX
You should watch this videoua-cam.com/video/QCMMv2CoFAg/v-deo.html
@@SergesMike will a reprogramming box work even if the phone won't turn on? I'm thinking it is the power ic has gone bad.
Yes. You remove only the chip and place it in the socket on the box
@@SergesMike I have heard that the data will be encrypted a chip-off data recovery is not possible with modern cell phones because the phone companies encryption.
Osm
Phone shows No service I tried manual network search but still not showing anything is it because network ic broken ?
First check imei and baseband
Maybe, but u have some steps to go through before suspecting network ic.
First check the network cable and the line if its not broken
If okay try changing P. A ic if still not working then you can go now for the R.F which is the network ic if you change and it doesn't work then reball or change power ic
Thank you
The power ic and cpu are they the same
No bro
Or you mean in what way?
Ok got u bro good work keep it up

You don't fix faulty ic's
You only replace them
Except its the rom that you can repair by flashing or reprogramming
Idol where can i find a bluetooth in the mother board or there non?
It's merged with the WiFi ic
