Nexus 5 No Sim Card - Pins Damaged? - Nexus 5 Q&A, Help & Troubleshooting

Micro sim adaptor got stuck in the sim tray of my 2 year old nexus 5 (yes stupid mistake) but I very carefully followed instructions by droid life and recovered the sim tray. But now phone doesn't recognize the sim anymore...
I am sure either the pins are damaged or have loosened leading to no contact with sim... I think my options are:
1. Try to add a piece of shim to the sim tray to create better contact - should this go above the sim or below?
2. Dissemble the phone following ifixit videos and try to solder the broken pins - i don't have any soldering equipment and its been ages I did something requiring such precision
3. Buy a new motherboard sim tray and replace - does this also need soldering?
4. Buy a broken nexus 5 and do the same as above
5. Or use the phone as an android pod.
Any suggestions appreciated!

I have zero fine soldering skills. I called a few cell repair shops and, even though they will replace power buttons and USB ports, none would replace the sim card tray because there are very fine components and solder points on the other side of the sim tray. Had to buy a phone with a busted screen to use in the phone.

Thanks for replying. Did you follow any particular guide to replace the motherboard + sim tray like iFixit teardown etc.?
I am not an electronics engineer nor a DIY expert and hence a bit worried that I might damage something else in the process and make the phone even more useless...

Replacing the motherboard was very easy. The sim tray, wi-fi chip, memory, etc. are all attached to the motherboard. The sim tray and motherboard are not separate pieces.
It's very easy once you watch a few Youtube videos about removing the plastic back, removing screws, etc.

Flex Cables in phone - Information

Hi friends
I am having an handset(Tilt) with flex cable problem, but wondering if flex cable can solve my phones problem where it is doing the following:
-Not accepting the SIM.
-phone is getting hanged any times, speed is also very pathetic.
-keypad is pressed on its own.
-Phone is not accepting any charger but charging with PC USB.
These are some of the major problems, I wish if someone could help me out in knowing what work does a flex cable plays, coz the technician is charging so much to change the flex cable & giving me no assurance as to what problems will be solved. I would like to know from some of those technicians here who knows something about hardware. Mike I am talking about you specially.
I would like to write this in our XDA encyclopedia given the case I get proper knowledge about it.
Looking forward to answers.
This is quite difficult to answer without testing. The SIM not being recognised will in itself slow down the phone or even create a full blown crash.
It's not stated what flex cable we are talking about. Flex Cables are just multi wire connections between circuit boards. Phones often have 3, 4 or more flex cables. For example between the the physical keypad and the motherboard or the d-pad and the LCD screen or between screen and motherboard etc etc.
It IS possible a flex cable can get damaged. This normally happens in phones with a slide out keyboard where the flex-cable has to roll back and forth as the keyboard slides in and out. However, such a cable would not I think change the charging behaviour of the phone.
It charges on PC connection but not charger connection. To me that normally indicates a USB port connection problem - bent pin in the slot, possibly even crossed pins or a cracked or dry solder joint between the usb port and the motherboard.
Another thing to consider is whether all the battery contacts are making good contact with the phone. Here again the multiple connections between battery and motherboard can become dry or cracked leading to erratic or underpowered connections.
The keypad being pressed on it's own can again be caused by different things:
1
It could be a faulty or loosley connected flex cable
2
Pressure being put on the digitizer screen by something under the bezel or just a damaged digitizer layer
3
A key that is not releasing from the keyboard properly (is it always the same key or group of keys?)
4
Moisture at many different places inside the phone, including keyboard, d-pad etc. Even when dried out, the residue or oxidisation can continue to cause problems.
So, I would not rule out a flex-cable problem, but it might not be the only fault. Unfortunately then, the technician you spoke to may be correct and it is not possible to guarantee it will solve all problems. Having said that, I would want to say to the technician that I am not going to pay for a new flex if it does not solve any of the problems.
This is where it becomes difficult to decide whether to go for paid for repair or to attempt the job yourself.

6045i - Is it possible to convert this into dual sim?

Hi there, I bought this phone second hand quite some time ago and I actually liked it a lot. But I bought it on the premise that it was dual sim, which it isn't (I got a fair discount for that).
But now I'm wondering if it somehow possible to turn this into dual sim using the micro sd for the second sim card? I tried reselling it, but it's just not that popular here in Germany.
Any help or advice is welcome
Many thanks in advance and sorry if the question has been asked before.

You'll have to buy a dual sim adaptor.

Do you have a link for that?
And does it allow for both sim cards to be active at the same time?

I'm not so sure. Can't post a link as I haven't reached the 10 post limit. Search for magic-sim on Google.

Unfortunately, magic-sim does not allow both sim cards to be online at the same time.

Seems like nobody has chimed in yet to say that a dual sim adaptor will NOT work on this phone. Dual sim adapters are often designed as a flex cable with one end plugging into the normal SIM port, and the other end extending out with 2 SIM card ports. Since this phone does not have a removeable back, it's pretty much impossible to use one of these adapters since this phone has the closed tray design for the SIM card. You would not be able to insert the adapter into the SIM slot and be able to shut the tray into the phone without possibly damaging the flex cable.
However, if the flex cable is extremely thin enough, it might be possible. I've never owned or seen an adapter so I can't say for certain. You have to take into consideration too the Idol 3's SIM/MicroSD tray is designed to have the SIM card go in first, before the MicroSD. So it might be tricky getting the SIM card to stay flat in the tray while you attempt to push it back into the phone due to the cable being bent when closing the tray.

Thank you very much for the detailed answer.
But my original question was meant differently: I wanted to know, if it is possible to change the sim/sd card tray to a sim/sim card tray? And then flash the firmware of the dual sim version and so on.

I dont think so...
Its related to the whole motherboard.
But did you think about trading it with a person which has the 6045K?
If you are both in Europe,there shouldnt be a problem with using the warranty,as you can just send the device to a repair shop.
For example,if you and I were to trade our devices,I could just send it to repairs in my own country,as long as it is in the EU.
So,if my 6045K,bought in Croatia,breaks,you can send it to repairs in an official Alcatel Repair Shop in your own country(but the repair shop must be official,and you must be in EU too)
If you want to know more,feel free to PM me.

No reception in some places

Hello! So I have an Nexus 5 D820 and after changing my battery in some areas of my city or my country I don't have any reception. While writing this I popped the battery cover and applied a little pressure with electrical tape to the black wire which I believe is for the reception but I can't tell if I fixed it because most of the time I have reception. So what should I change to fix my reception - only the little black wire or the hole bottom PCB with the plastic cover ? Thanks in advance!
Since it's working at some places it's probably not your device's fault that it can't connect at some other places. Nevertheless:
To change your battery you must have removed the motherboard cover to remove the battery cable. The GSM antenna is on the motherboard cover and is connected by simply touching 2 small conductive pieces on the motherboard (with the phone facing down and the motherboard cover removed, these should be at the top right area of the motherboard). There are also 2 wires (along with a big wire strip) that connect the 2 bottom edges of the motherboard to an extra little board below the battery (where the USB port and other components are). Those are antenna extensions, one of these is probably the black wire you are talking about. The right one is for 3G and the left one is for 4G (with the phone facing down), don't remember the colors. If you have a problem with data connection and not normal cell reception, check those 2 wires. The 3G and 4G antennas are on the black plastic cover of that extra little board and connect to it with a similar way the GSM antenna connects to the motherboard (each one has 2 gold flexible metal pins). You didn't need to remove that plastic cover to replace the battery, but if you did, remove it again and check the connector and those gold pins.
Whatever you do: NEVER DO ::ANYTHING:: WITHOUT DISCONNECTING THE BATTERY (xp talking).
Shutdown the device normally, remove back cover, remove motherboard cover, disconnect the battery cable, and THEN do whatever you have to do.
The screwdriver is usually metal and can short things. You really don't want to short something on the motherboard with the battery connected.
Thanks! I started losing signal after I replaced my battery(before that no problems whatsoever), but couple of days ago I opened the phone again and applied a little pressure to the both wires and I hope it's fixed. Also today I'm going to the place where I'm losing signal and I will find out.

Why not to store your SIM Card Adapter in your Tablet

Hi everyone
I managed recently to broke my simcard reader on my lte tablet by storing my empty simcard adapter (microSIM to nanoSIM) in my sim slot. When i tried to remove the adapter it got stuck on some pins inside and broke some of them off as you could see on the pictures below
After i had to search and order the right simreader which is : https://www.mouser.ch/ProductDetail/Alps-Alpine/SCGD1B0209?qs=raqtESnDWsCnTRfNgBUKsg==
I desoldered the broken slot which wasnt too easy because it needs a lot off heat ( in my case 500-550° Celsius that enough heat reach the small tip i used) and even with the most possible caution i lost one of the attachement solderspots as you can see too on one of the pictures. To lose the pins i added some fresh solder over all the pins and heated it up equally so that i could carefully lift the whole black ground plate from one side to the other.
After this its very important to clean all the old solder and add fresh one.
To install the slot back on i soldered first the attachement spots on while checking the pins
are fit to the right spot. Then i soldered the pins one by one with the help of flux.
The port is now working again but i really have to say its not a easy job a beginner can do with basic equipment its way more complicated than de- and resolder the battery cable
Here i a video that helped me a lot before i started my repair:
I hope this little Guide and Warning is helpful for you

OPO No signal, service issue

Dear all,
I kindly ask your support for the following issue: I have got a OPO lineage os 18.1 which doesn't recognize any 3G\4G signal anymore.
here below the description of the issue:
as OPO is my backup phone I have a nano sim so I used an adapter to put the sim inside the OPO, unfortunately removing the support the adapter got stuck inside the sim reader so I had to disassembly the smartphone to manually release the adapter blocked by the pins of the sim reader. After this procedure and after the connection of all the parts including the cable antenna, now OPO detects the sim, prompts to ask the sim code but after that I get NO SIGNAL.
as I wrote the antenna cable is connected on both the terminals. What do you think? Antenna cable damaged? Sim reader damaged? Something else?
I asked to a smartphone repair shop and they quoted 30euro.
attached some pictures
any support or opinion will be appreciated
thank you
