After dismantling, SIM card is missing - Touch Cruise ROM Development

Help!!! I had to dismantle my Polaris in order to replace the little plastic piece that keeps the SD Card slot closed to avoid the dust.
When I opened the case, the SIM card ribbon got disconnected, but I put it back tightly into the slot again before closing it again.
When I booted up, it said SIM Card is missing. It's like hell! I opened lots of times and nothing works. The SIM slot appears to have a GND connection to the main board and it comes with a little piece like a pillow that sits between the two pieces (SIM slot and main board). It makes contact when you close the case, and I think it's alright.
What can I do? Did somebody have the same problem? Any technician here?

I had the same problem, I had to buy a new sim reader, and replace it, you probably damaged the flat cable. I replaced it and now it's ok.
I bought it here http://cnn.cn/shop/touch-cruise-card-module-p-3676.html
Hope I helped.

Hello! Thanks for your answer. I'm alone with this...
I've just ordered a SIM reader to the website you told me above. But I'm worried about having bought it, because I actually don't know whether the SIM reader is broken or not. Is there any way to know if it's the data cable or the GND signal?
It's so strange...! I just opened the case, and the ribbon got out, but I didn't force it. Is it so weak?

Is I believe it's very weak, i Didn't force it either, I believe you can check the continuity of the contacts on the sim reader to the end of the flat cable. mine was broken, but i didn't know how, I was very carefuller.
Good luck

Thanks a lot! I think my cable is fine, not much straight, but intact. I contacted a technical support service that fixed my Polaris a few months ago, and they say it's pretty common to have a problem like ours. The guy there told me that it's sometimes the socket that fails, due to an abrupt move while removing the upper case.
For the moment, I cross my fingers until I receive the new SIM reader. I know how to install it, but... if it's the socket what is broken, so long, Polaris

It will be the sim reader, you´ll see.
Say something when you fix it.
Cheers

blah... my polaris is also saying "sim card missing"... no hard resets and reinstalls helped... and I just didn't do anything unusual...

Did this error appear after opening the device or ocurred all of a sudden?

all of a sudden... and they don't want to repair it because there is some small gray smudge on the screen classified under "mechanical problems".
Did you have any success replacing the sim card reader?
I think I am going to buy the above mentioned sim card reader and replace it myself... hopefully it is ii what's making the problem.

Hello
Same problem here after changing the full face houseplate but I realise that the sim flex cable is broken. With a large amount of patient I managed to fold it and put a little of fixo tape on it and now is working. Anyway I know that I should buy another sim holder soon.
A mi me paso lo mismo despues de cambiar la carcasa pero me las arregle con un poco de celo. Al principio crei que era tambien la masa del sim holder; incluso pense en soldarlo con un cable, pero al sacar el flex vi que estaba partido. Seguro que se arregla cuando tengas uno nuevo. Saludos

I got it! As soon as the new SIM card reader was put it recognized the SIM card! So I think the problem was a broken line in the data ribbon.
I bought the SIM card reader from the link above. Thanks A LOT!! and thanks for the link, @afsc !!!
My Polaris is back again to life.

You're welcome.
Good to know that your Polaris is working again.
By the way where did you get the little plastic piece that keeps the SD Card slot closed? Mine is in a bad state, and i would like to replace it.
Cheers

For me replacing SIM card reader worked as well. I must add that Orbit 2 is much harder to dismantle compared to Polaris.

Mini-sd slot broke

Today I removed my minisd card and put it back in shortly after, but something went horribly wrong
Somehow I broke the thing that holds the card in position so now it wont stick in.. so I tried to make it stuck in with a paper which works but it doesn't get recognized then, I guess the mechanism which holds the card always turns on a switch thats tells my wizard to start reading the card
Does anyone got any idea to fix it, cause this sux big time (I bought the phone a few months ago for €200), I cant find my receipt but ill try to get a copy of the shop .
Im so pissed right now
Nobody knows, the warranty is overdue
Could I open the phone and maybe fix it myself?
I got the service manual but not the tools, anyone ever seen the inside of the phone, would it even be possible to fix it?
bump ...
similar problem
Hi there
i had a similar problem - had to buy another htc 8125 and unfortunately it came with a broken slot for the minisd card. At first i thought i wasn't pressing the card enough for the thing to click and hold it. Then i realised it was broken. As far as i could see from the little opening there was a white slider which is pushed down by the wider side of the minisd card. It has a spring behind it and somehow it has to click in down position and hold the card.
i tried to push it down with a very very small screwdriver and understand the way it worked. With my bad luck i pushed a little harder and broke that white slider. It just broke in the middle and one part stayed down and the other was pushed up by the spring. It broke exactly at the place where it was pushed by the memory card. So my card was not jumping anymore out - it just stayed in but was not recognised by the phone.
I didn't know what else to do so i found some instructions on how to open the phone and went for it with the hope to reach the memory card slot an hopefully fix it. HTC has taken good care of the stupid slot. It is soldered to the motherboard and nothing much could be done. There are 4 points that hold it but i didn't go that far to unsolder it (didn't know how many springs and other parts would jump out of it). Anyways - what i noticed was the following:
there are two small "plates" at the bottom of the slot. Wheny ou isnert the card they touch and i think this is what makes the slot active and knowing that there is a card in it. I had some dirt betwen them and that was preventing them from making a contact. After i removed that small piece of dirt and inserted the card it worked like a charm. It stays so tight in there now that i hardly can get it out - which is not that bad because i can always use the usb cable to transfer whatever i want.
I think i still have those manuals for opening the phone, so if you decide to go this far and can't find them i can send you an email.
Hope i was of any help
There's no need to open or disassemble the phone to repair the slot,just apply a thin layer of any adhesive tape around it but make sure you do not cover the connectors and insert the card firmly in the slot.
Cheers !
But well even if I push it in it doesnt get detected(I added a piece of paper to hold it in but it didnt detect it still).
I think ill buy a torx screwdriver and open it.
I'll still advise you to check the mini sd in some other phone,if it still doesn't get detected than get a new one or it may need to be reformatted.Opening up the phone might lead onto more problems.
Cheers !

SIM Card Read broken ?

Hi,
after i change successfully my harddisk, I try to use
the Sim Card for the 3G Connection for the first Time Today.
I use this Sim Card normally in an Vodafone UMTS Card.
My Shift displays only the Message "Sim Karte fehlt"
I have have no Idea where the Problem is.
Can somebody help me.
Thank
Andreas
If you have replaced the 5mm height drive with a 8mm drive height you will be putting excess pressure on the SIM card socket. This could be causing a bad connection or maybe even damaged it completely.
Try replacing your old drive and see if that restores SIM socket function.
Please be aware that any modifications done by people on this Forum are NOT fully tested at this time and you do them at your own risk.
I fear you will not be the last person to suffer this problem.
Thank for your help.
I know that i do all modification on my own risk.
I open my shift again an I take a look on the read, the SIM Card is not fixed in der Read.
If i insert the SIM Card it sound like the Card is fixed, but if i release my finger it will be squeezed out again. I think that i have a Problem with the Metall tongue that should fix it in the read.
Is there anyony else how had that problem ?

Broken screen and sim card slot

Hey guys,
I have a broken Galaxy Express since last summer. It has 3 defects:
1. The screen glass is completely broken but the touchscreen is usable everywhere.
2.The sim card slot doesnt detect any sim cards anymore. A relative of mine put a sim card in it upside down and while pulling it back out i destroyed one golden pin.
3. My proximity sensor doesn´t work at all anymore because one crack is directly above it.
Do you think this is reoarable and is ist worth it as the device is already quite old an I am very afraid of opening it myself.
What do you guys advise me to do now?
Thanks, Paul

I found this website here that you can check for the screen.
About the SIM, I saw a video of a disassembly and both Sim card and SD card are in another board. I can't find them, but if you do find them, watch this. It's really easy to do
Good luck, mate
But where do i get a new sim card slot from?

Stuck SIM tray

hello guys, yesterday I was trying to switch my sd card and what I didnt expect, I couldnt remove the tray.
I thought maybe sim or sd was stuck, so after a while, I was able to gently remove it with a knife.
As it turned out, that wasnt a problem and I still cant remove it fully...
ye...why does this have to happen... anyone have some trick maybe? Or experienced the same problem?
Thanks
It's possible that your SIM card (or a storage card) has become disloged, ie; is not laying flat in the tray. I think the best you can do is to gently push the tray back in and lay it flat face up and see if you can shake it a bit to get it to settle into the tray. If that does not work, I would take it somewhere for repairs.
Just cant believe this really...
I managed to break it, so the stuck piece is still in my phone, but now I am at least able to put a sim and sd card into it.
Contacts little bent, but its how it is and the phone works. Will have to ask about warranty service on this, I am really curious, what will they say...
So be aware, even thing like this can happen...
Yes, this SIM tray is very fragile. You are not the first.
Exact same thing happened to me. I believe there is some clip or contact that detects when the Sim tray is inserted or ejected and it gets caught there. They used a flimsy plastic Sim tray and it breaks in the same place.
The SD card and Sim tray still work. Just have to reset the phone when you change it for the phone to detect the changes.
Happened to me exactly like yours...i used a very this bit of plastic, with a bit of blue tack very firmly attached to the plastic and gently, VERY gently pushed it in to the sim/sd card slot and only took 2 attempts but the bit that broke off came out!!
Then went on Ebay and got a brand new sim/sd card tray and voila!
Cost me £4.50 for new sim tray, but working perfect now.

Any ideas on extracting w/o breaking the tray?
I have the exact same issue as the OP (before his tray broke).
Does anyone know any tricks to extract a stuck tray without breaking it?
edit: nm. Broke the tray. Took no force at all.
So the issue here is one of the SIM reader pins is sticking up and is catching the tray. Trying carefully to bend it back where it belongs.
edit #2: Can't bend the pin back w/o disassembling the phone. Going to borrow a heat gun.

The SD card and Sim tray still work. Just have to reset the phone when you change it for the phone to detect the changes.

So you meant when replace that sim tray, you need to hard reset so it will detect the sdcard? Because I have sim tray replaced, sim worked but sdcard wasnt, it keep fail to format at 20%.
You must have damaged some pins. For me all my.pins are intact and the broken piece is still in the phone. I have to do a hard reset for mine if I want to change the Sim or SD card

Same here. Damaged SIM reader pin. Tore the phone down and it's not clear if it's repairable or not.
Regardless, I'm writing off my G6 (just 1 month after I got it). I'll pickup a V20 for now, so I don't have to look at another SIM tray.

I went to LG and they ask for mainboard replacement cost $400, what a joke! Looks like they wouldnt replace only damaged part.
Even if you replaced it. It won't be long before it breaks again in the same spot... If it was a metal Sim tray it would be a lot better. I'm going to avoid LG phones from now on.

Bad design
I have had 3 LG G6s, each one has had this happen. It sticks in the corner by the sd card contacts. After it catches it will not read SIM until i get a new tray. I think there may be some sort of pressure switch. I wish LG would replace it with a G8x...
Even the models w/o dual sim capability have contacts for a second sim. These rub against and can get stuck at the tiny pads on the underside of many mSD cards. This will cause the tray to get stuck in the frame for additional friction. If this happens to me again i will try to pull the tray out with some adhesive tape to be able to apply force in the middle or at the left side, where the sd sits, instead of the opposite side via the hole.
Especially the newer, bigger mSDs seem to have such pads, none of my old ones has one, that's why i didn't test whether you could sadely remove the pad. Probably there's the bare flash die underneath.
I solved the problem...its called the LG V30!
Love it!

Hi, I got the same problem. The tray broke down only for the SD card and SIM slot is intact. But the phone does not anymore recognize SIM card. So do you think that I did not damage the reader and it's only a matter of getting a new SIM holder?
If you ran into the issue with a sticky mSD, the contacts for the second sim msy be bent/broken/shorted. Whereas only a short may prohibit use of the primary sim slot. And the contacts may not even be soldered to the pcb on a single sim phone like p870. Otherwise just the flimsy plastic tray broke. On my Iphone 4s it was made of metal. And the lever to push the thing outwards was centered and not to the right side, which makes even pushing out an empty tray difficult.
I finally got replacement tray and can confirm that SIM reader started working again. So it indeed seems that there is a pressure switch and it did not activate when the SD card compartment was damaged. No I just worry do I dare to remove sim tray ever again.
My current 128GB mSD in the p870 has a sticker on the back like most mSDs at higher (32/64GB and up) capacities, but this time there's no friction with the useless contacts for dual sim.
But anyway, once the tray has been pushed out slightly, you have to try to grab and pull from the opposite side while pushing the pin in, otherwise there's high friction.

Stuck sim card tray. Asked around. They say they'll have to "open" my phone up?!

Hello.
My sim card tray has been stuck for a while now. After watching a few videos , I tried to solve the problem but with zero luck. I asked around some service centre and they say they will have to literally open my phone and remove the stuck sim card . If they try to remove the tray otherwise, chances are it will break.
The point is , I am not too confident about getting my phone sort of disassembled. I am worried doing so will affect the my phones performance.
Please from some one who know about this.. let me know what I should...
Thanks in advance ~

I had this issue and still do my eject dont work I have now broken probly 4 sim trays on s8 they are cheap as hell.
i use the tool in the hole and angle it and pry it out
But I but yours is broken inside,
Once I just finally ripped it out hoped for the best The sim stayed inside So with luck a toothpick and a dab of super glue I got it out as well....
I have been completely infuriated from since the first time my tray broke All over a samsung evo sd card which apparently has a slightly larger sim than most
But yea if none of the known ideas work in the end opening it up is the final solution
