Dear all,
One of our businessmen inflicted unintended damage to one of our BAs.
It looks it has fallen, as the screen part which moves to display the keyboard has a larger gap on the left side,, nad is has scratch in the chassis lower part.
The green button does not do the nice clickety feedback it should do (the red does).
The phone keeps opening the phone program and keeps trying to call forever. I can cancel the initiated call, but it opens up again.
I believe sending it to Authorized Service (it's 6 months old, but on warranty) will take hopelessly long, so I am willing to do the repair job myself.
I would like some directions, if there is a service manual somewhere on teh web, and it looks like some screws are Torx T6, but some others are even smaller, and I don't know which screw is that.
If someone can guesstimate which piece is probably damaged and point me an e-shop which sells spare parts, I'd greatly appreciate!
EDIT
I also want to hack around the broken button, removing the phone function from it, and assigning it to the'windows menu' hardware key.
I haven't found anything on how to do it on the forums or wiki, but I believe it should be doable thru the registry - I just don't know where to look.
/EDIT
Many many thanks,
Brazilian Joe
I have a question regarding the changing process of the G1 motherboard.
I bricked my device by flashing a SPL, so it does not go past the G1 screen. Now i bought another G1 with a damaged touchscreen (screen works, but doesnt recognise the fingers) and want to use the working mainboard to insert into my G1.
Is there something I have to pay attenton to like some software barrier or something like that?
My plan was to only use the mainboard and keep my UMTS/GSM and GPS modules. Will this work? Where is the baseband stored at, on the mainboard, or on the GSM module?
Thanks.
Unless it uses different frequencies, might be easier to just swap the screen.
I've read the TechManual and its easier to swap the mainboard.
when you take it apart, remove the camera, IMEI Plate, and motherbaord as one piece. Transplant that as a whole, that way the IMEI is correct for the board, and the camera connection will not get fubar'd as they often do. Everything is on the mainboard, the other modules are just modules- the phone will run without them. BE CAREFUL not to pinch a coax cable when putting back together!
MUCH easier to swap the board, the disassembly beyond the motherboard is a PITA. I have been there, done that...it is a long process with many chaces for screwing up a cable.
What do you mean by the "IMEI Plate"?
the black sticker plate that carries all the imei and other important data that you see when you take the battery out
It is double side taped on loosely, gently lift the camera module and it will lift with the ribbon as an assembly

Hi
I have the c5502 with the bluetooth/wifi problem , the repair service told me they can fix it with bridges or smth and the problem will appear again,
First i dont believe them that much i just feel that they wanted me to pay for a new PCB
Question: Is this problem really fixable or should i buy a new one
Someone told me he will reweld the wifi and it is fixed
Note: The problem was temporarly fixed when i press hard on the back next to mic 2, but no longer works
Judging by your description, it might be that the WiFi/BT chip isn't attached well - some of the balls in the BGA (Ball Grid Array, look it up) have cracks that prevent proper contact.
If this is indeed the case, it can be fixed by reflowing or just directed heating of the chip area to the melting temperature of the soldering alloy.
However, this might not be the problem - and if it isn't, there might be a host of reasons for it.
You need to correlate the location of the WiFi/BT chip and the pressure you're applying.

could you tell me what is the bridging he talked about ?
He might be suspecting something else.

I have fixed my WiFi but bluetooth is still dead.
The WiFi problem is actually a poor connection between two boards inside the phone. There's two boards that need to make contact but because they aren't hard-wired together they rely on a touch contact. There's a shiny foil square on top board (main pcb) that has to contact conductive square on lower board. The shiny foil square looks like it gets compressed over time which is why the wifi only fails on some phones after a while. Some phones will be fine but I think it's just poor engineering to rely on a soft touch contact!!
When you push in the back against the mic you are pushing the boards together to make contact.
I fixed by placing some of the screen adhesive (which I had plenty of after removing screen) underneath the spacer pad that is under the bottom board. This forces the boards together and keeps the WiFi going.
However, I thought this would fix bluetooth but no such luck. Perhaps there's another connection that's not right somewhere?
so i sent it to a repair center sony told me the board is fried, i dont know what this means , everything works except for wifi bluetooth, they are both working until now, i think they heated the wifi part on the board

Hi,
Can you please let me know that how did you open that phone? did you opened it by your self?
Is it possible to open from back side only?
Do you have pictures for wifi solution which you described above?

Hi sorry but don't have phone any more. Don't think I have pictures any more either.
You cannot open from back side only. You have to take off screen. Look on youtube to see how it's done.

Yes, you'll need the screen adhesive stuff. Can find on eBay or Aliexpress or Witrigs etc.

old thread but just in case some zr user are still searching for an answer
there is a chip on main pcb which controls wifi and bluetooth, but sony didn't soldered it correctly and thus it needs pressure to make connections with pcb.
Only permanent solution is to apply heat on that chip ( after disassembling pcb from phone ) and then it will work for forever.
My phone's ( zr ) wifi bluetooth and nfc wasn't working, so i dissembled it and took the pcb to a laptop repair shop and told them to apply heat on that chip to solder it correctly ( as i don't have that instrument which is used to apply heat on small point ), and after that it is working without any issue. :highfive:
Note:- be carefull while removing screen as it is very fragile and will brake easily if not handled correctly ( yes i broke my screen and using an after market now which costed me Rs1800 ( for full folder ), i was lucky to still find its screen .
Saw Sooper diff DDI dijauhkan I'd do so
So, the screen on my Note 4X broke, and I wanted to replace it. Long story short, the battery is glued down hard as **** and I managed to damage it, and it burst into flames. I'm fine, I was prepared, nothing but the phone suffered any damage.
But now I'm sitting here, with a phone that's basically still fine minus the frame and the battery, and I still want to repair it.
I'm faced with two questions, first of all, I managed to find (I think) every part I need, but one eludes me. I don't even know what it's for. You can see it here (minute 9:11-9:27):
https://youtu.be/MQazwoEssN0?t=556
It says "C6_LEDFPC_V1.0" on mine. Google tells me nothing about that, and it's not a part I have seen on the repair shop sites. It doesn't even seem to be present on complete frame+display assemblies like this one:
https://www.aliexpress.com/item/LCD...edmi-Note-4X-hongmi-Red-Rise/32810566637.html
And apart from that, I wonder if I missed any part.
I still have:
A new display+digitizer, the back cover, the mainboard with the SoC and the two cameras, the PCB with the charging board, the battery cable, the sim tray, the fingerprint reader, the loudspeaker.
I need:
A new frame, an earpiece, the mainboard flex cable, the side key flex cable, a battery, and the one mysterious piece.
Is that everything? Does everyone has a basic list of all the parts?

I've been thinking that in the video, the guy switched on the phone without that part. so that part shouldn't be a very major component. In my opinion, it can be some sort of sensor. I personally feel its a magnet screen sensor for covers with smart wake up function.
The reason I say this is because when i touch a small magnet on the entire front panel, It gets stuck on that same point.
However I am not very sure as the smart wake is not triggered. Maybe it is because I am on LineageOS.
Hope It turns out helpful.
You will probably need the vibrator motor too, its quite small and easy to lose as I've found.

That part is the LED for the capacitive buttons. Not important at all if you cant find it
Hi there,
I am having some issues with my Z3C and thinking of doing a repair myself.
A few months ago the first issue started, still present: the bottom bar buttons (back, home, apps) require extra pressure. This was probably my fault as I might have bent it a bit during cleaning, resulting in this damage (not that strong of a bent, but somehow it screwed it).
The second problem started yesterday, after a bit of rain I have now the full second digitizer column from left completely dead (tested with service menu).
So I was wondering, has any of you already gone through the process and can give me some indications? Ideally I would replace only the digitizer, but I hear it's better to buy it bundled with the LCD as making them match tight is always the very complex part of the job?
Please also share links with parts that worked for you, I am thinking of buying the part from US or China (but would like OEM/original).
Thanks
I have found these parts:
http://www.witrigs.com/oem-lcd-with-digitizer-for-sony-xperia-z3-black
https://www.amazon.co.uk/Xperia-compact-Display-Digitizer-Replacement/dp/B0148JVO9E
https://www.replacebase.co.uk/sony-xperia-z3-compact-replacement-lcd-touch-screen-assembly-black/
As I understand OEM does not mean supplied by Sony but rather should have the same parts with same specs..but of course it will not have 100% :cyclops:
I would like to know if somebody has replaced it already and what is their experience; I am not going for digitizer only but digitizer+LCD
I have a similar issue on my Z3C. My entire middle row is non-touch responsive.
Did you manage to repair your phone? Was it worth the hassel?

Here you go, to avoid writing everything again, I've posted this in other thread, still using that screen, and happy with it.
