Hey what's up guys.
I recently purchased a new camera module for my M7 hoping to fix the purple camera issue. Headsup, it didn't fix it. Opening up the phone wasn't all THAT hard. Granted it is harder than your galaxy S5 (that's what she said). but with a little bit of patience and the right tools, it can be done without damaging the phone.
So my issue now is, Wifi is technically working. the signal just sucks. And I haven't been able to pinpoint which spring contact leads to the back housing (which acts as an antenna). Any ideas?

Hi guys.
Yesterday i replaced motherboard on my N1, previous motherboard was broken, after replacement everything is work fine, except wi/fi and gps. My wi-fi module catches the signal slightly, like w/o antenna, gps have not been able to get to work now.
My question is, where is wi fi module exactly? I try to made some photos of my donor phone with pars in some days, but maybe there is some document or photos with this parts, that I will be able to analyze on my phone
If I remember right, the wifi antenna is hooked up near the upper left side of the phone (screen facing down). Verify that is fully connected.
Check out ifix it they have a tear down of the nexus one so you can see where everything is.
Thx for your advices, i'll try to check antenna
OK I have been using my N1 for almost 2yrs now. I love it, but out of nowhere the connections on bluetooth, wifi, 3G, and occasionally cellular drop. Coincidentally it happened when 2.3.6 was released and I refused (updated since no change) the update. When I use my bluetooth headset I'm told I sound like I am underwater. I installed CM7 thinking that would solve it (maybe it's a stock ROM issue) but it was still the same. I can put my phone next to the router and still show (1bar) a poor connection .
OK so what can I do to fix this? I don't want to purchase a new phone (besides this glitch it looks mint) right now. Also I don't really have the cash for it either. Someone said the antenna may be loose (don't know how that would happen) and I could open it up and fix it.
Now you all Mod software but has anyone actually opened up an N1 and is there really a way to tighten the antenna? Please let me know if anyone else has had this issue or is there a way to test for a solution.
Thanks
A little more info
Was just on a cell call and noticed that the green cellular indicator turned white (no idea if that's related) it is back to green now and full. However this seems to be a pattern of being green 3G and Cell strength to white. Hope that provides so more info to someone trying to help me.
Green/white is an indication of connection to Google servers, nothing else.
Radio is only responsible for 3G data, bluetooth and WiFi are completely different entities and aren't related to radio. If you're experiencing bad reception - most probably your antenna contacts need cleaning or are misplaced, open the lower cover (not the battery one) and look there (this cover IS the antenna - just don't know which one).
Special tools?

OK found a teardown on youtube of the Nexus one so I understand the antenna is on the bottom. However it looks like they used a special tool to open the case on the bottom. Where would I get that? Also considering I paid for it outright (yep unsubsidized direct from Google); even if I'm out of warranty would you recommend (if this is something more complicated) I send it to HTC for repair? Someone else said the Broadcom chip may have gone bad if both the wifi and bluetooth seem to stop working or have poor reception. Not sure if that seems correct since if it went bad I would think it wouldn't work at all but before I make tool marks trying to take it apart I figured I'd ask.
I'm not sure the repair will be worth it, financially.
If you want to open the lower part of the case - you may only need a small flat screwdriver and good hands, to avoid scratching the surface.
Something else now
OK now voice dial command isn't working when I hold the bluetooth button. Maybe indeed it is the chip. I was able to take off the plastic cover but I need to get a T5 screw driver (lol for some reason smallest I have is T6) so I will get one tomorrow and see how it goes. There is one more cover to remove and put back on. Financially since I paid full price I'm not sure why it's not worth fixing? I figured HTC would charge around $100 for a repair. Which is less than going price for a new (i.e. Galaxy Nexus II) phone . Also I haven't seen any new phones with a trackball (which I love for the notifications and when I need precise movement) so I really don't want a new phone till they add something like an optical trackball or improve precision on finger location. Also I might get lucky if the credit card I purchased it on will cover a repair (they double warranties) and I still have a few months left.
Nope!

OK got the required tools and took it apart (both covers on the bottom) and then re-assembled it back, making sure I seated the vibrator motor back carefully. Turned on the wifi and still have same issue. So guess my phone is broke further than I can repair it. Thanks for your advice but unless there is software to check that chip it looks like only option is HTC.
Yes, looks like it might be damaged beyond the home repairs capability.
Financially - If I were you, instead of spending $100 on Nexus One repair, I'd sell it for parts for $70 or so, added the $100 you wanted to spend on the repair, and bought a used MT4G in good condition. You'll lose colored trackball (and get a trackpad - which, if you use Sense ROMs that this phone runs perfectly, will be absolutely useless), but gain WAY better phone, in just about every aspect you can think of. The same applies to any phone you can get for cheap from "outdated" MSM8x55 family - Desire HD/Desire Z/G2/Desire S (some of them aren't compatible with T-Mobile frequencies, put attention). I know this from first hand experience, since until recently I had 3 of them - Nexus One, MT4G, and Desire S for my wife. Guess which phone did I get rid of?
But - just in case you'll want to follow this advice and settle specifically on MT4G - make sure you read MT4G forums thoroughly before you do. There are 2 weak points for MT4G - the screen (more important) and the eMMC chip (less important, but still counts). Both can come in 2 variations, better and worse. Make sure you choose the better.
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.

wow thank you, i looke it up it should be simple
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.

Hi,
Thanks for your reply. Currently i had press with pressure back side and it's working for me.
But let say if i open phone as shown in youtube then do i need anything extra to assemble my phone again?
Thanks that you have write your wifi issue here and it will help others.

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
Hi, I've had thus problem for quite some time now and I'm not really sure what the cause of it is. A while ago I changed the housing of my m7 to gold and since then I've had some problems. At first my charging port started malfunctioning and no longer worked when I plugged it into my laptop. I replaced it and not it works fine but then the vibrating motor stopped working. I replaced that too but it still doesn't work and now my camera and volume button doesn't work either. I thought that maybe if I replaced the daughter board that it would fix those issues so I bought a broken HTC one off eBay and switched the daughter boards. It fixed things for the most part but vibration still doesn't work and apparently the owner was messing around with the Sim card connector on the daughter board and somehow broke the clamp to hold the sim flex cable. So I have no mobile network and it's currently useless to me. Since vibration still doesn't work I can't help but think that maybe it is somewhat a motherboard issue. I'm thinking that maybe some of the connections aren't clean because of how many times I've opened up the phone and touched all over. I'm thinking of getting done isopropyl alcohol to clean it and see if it fixes the issue but first I was hoping that maybe someone could help me out and tell me if it really is a motherboard problem.
Bought a broken phone and used the internals to replace with mine and everything is great. Finally got a camera without people tint.
Hey guys,
So I've personally owned this device before and sold it, however, luckily I was looking about on Craigslist and managed to run into a post where this lady was selling her Midnight 128gb OP3T for $10 due to the wifi not working. The phone is literally spanking new and the only thing I can think of is water damage. She said the wifi suddenly stopped working and spoke with OnePlus Tech support and wasn't going to pay $275 to fix it so she just wanted it gone. So I figured whats there to lose, right? I went home performed a factory reset on the phone and the wifi actually was working. Then I realized it's intermittently working. I found that out because after sometime it suddenly disables itself and I have to sleep the device for like two minutes and it'll kick back on. The proximity sensor is also dead too. I did the *#808# to test the sensor and nothing is generated. These are the only real issues this phone has. The loud speaker also sounds a bit off... I'm sure I could easily replace that too.. It could just be me. I've posted the snapshot of the proximity sensor test. The wifi was currently working when I took that snapshot and like I said it's a hit or miss.
I haven't gotten into the device just yet, however, I'm planning to check the water damage sticker once I do as that is my suspicion. I'm waiting on my tool set I ordered on Amazon at the moment. My question is, do you think replacing the wifi antenna cable will fix the wifi connectivity issue? The phone is currently on 8.0 Oreo and I haven't tried performing a complete reset/restore so I'm not sure that could be a fix. Also the phone doesn't get too hot and usually with water damaged devices the phone typically overheats pretty fast due to corrosion. I guess I'll find out after I open the device, but for now do you guys have any other suggestions? I've heard of the whole IPv6 intermittent wifi issues and can assure I have IPv6 disabled.
Thanks for taking the time to read my question!
The WIFI thing isn't something I think you can just replace, I think you would just need to replace the board right?
Yes, you would need to replace the mainboard of the phone. However 10$ is quite cheap for a spare screen and midnight black metal casing. Just find a cheap 3T with broken screen and switch mainboard with that one and you have a working phone. [emoji16]
Before doing that, check the phone's board and look for corrosion. If you find any, try cleaning it up gently, with some alcohol and if you manage to get it all cleaned up, try testing it again to see if it solves the problem.
If you get the schematic for this device and have a boardview program you could find the wifi circuitry..... it is more than likely some short to ground due to the fact that you are feeling heat.... due to liquid damage or not. Sometimes changing a small component can fix the issue but you need a microscope, heat gun, solder pencil, etc......
