This problem came out of nowhere. I have been using the same ROM for several months (version: 3.29.707.0 WWE) and have not installed anything new to the phone. If I slide the phone shut, it loses it's signal (in an area where I have plenty of bars). When I open the comm manager, turn off the phone service, then turn it back on I get the message saying that my SIM card is missing. When I slide the phone open and repeat the process of opening the Comm Manager and turning off the phone service then back on, everything is fine. Does anyone know if this is a hardware or software problem. I am going to re-flash shortly and see if that changes anything.
EDIT: I have just flashed to NGY Professional v1.2 - M2D Fix. Everything works fine when the device is slid open. As soon as I close the phone, it tells me to insert a SIM card. While the phone is open, I started the SIM manager program, it listed all numbers saved to my card. I then slid the phone closed. It kept the numbers displayed until I exited the program. HELP PLEASE!!!!
Kid gloves / TLC
Orflin, I have had similar trouble with my Tilt, but yours seems a bit more well behaved. In my case, the problem was physical. Your problem seems too perfect to not be software or firmware related. At any rate, perhaps my take will help:
Shortly after receiving my Tilt, my device began to intermittently lose power (resulting in a soft reset) or lose signal upon opening the device. I took it to a retail location and a representative was able to reproduce the issue. She then opened the device VERY slowly while pressing firmly on the action. This steady transition allowed the device to function with nary a hiccup until my replacement unit arrived that did not exhibit this annoying behavior.
I recently re-lived this when I decided to purchase an oversized battery with a custom backplate to replace my scorching hot, aging standard battery. Outside warranty, I needed a solution. I discovered that my new battery was ever-so-slightly slimmer in the dimension that forces terminal contact. I used cardstock to increase contact with the springy posts and cleaned the posts. The device now no longer soft resets, loses signal, or corrupts the display on opening. It seems that the jolt of opening the device can exceed the rate of compliance of the springy posts when extended and that this can lead to unpredictable behavior.
Since your device fails when closed instead of open I suggest the following:
1) Clean the battery terminals and the spring posts
2) Pad the compartment on the side opposing the springy posts to increase the force on the posts
3) Clean the underside of the display panel and the remainder of the sliding area
4) Clean the SIM contacts
5) Check and double check the action of the SIM panel (as well as verify power-loss on opening)
6) Retard the sliding action to the best of your ability
7) Power-on the device in the opposite user interface orientation (while open/while closed)
8) Reproduce the issue under unusual gross orientation (use the device upside-down, screen face down)
9) Use the device in a low humidity environment after desiccation
Wish you the best!
Bad electrical contact either on the SIM connector itself (remove SIM, clean and reinsert), or maybe more likely the connections inside the phone between the screen assembly and main body, the connector might have moved a bit.
same problem
I too have this problem recently. I have tried hard resetting the phone, getting a new sim. I will try all of these including flashing a new rom and report back. If anyone has any other ideas PLEASE help.
my symptoms for the doctors of the Kaiser World:
When my phone is slid open and I reset or turn it on phone works as normal and can make calls, receive messages, ect. When I make a call "open" then close the phone or close the phone then make a call it stays on full service until I press call. I get the error message "operation failed" and then "the SIM card is missing" until I slide it open and reset the phone in wireless manager, where it acts normal again with full service.
EDIT: Flashed ROM no difference, same problems
Took apart my whole phone looking for a culprit and to my surprise have found none. The ribbon cable for the sim card (my best guess) seemed to be in very good condition... I am now OFFICIALLY stumped.
Actually, it really sounds to me that this IS a problem with the ribbon.. My sons tilt stated its problems with the same way (except his would only work while it was open). All it takes is one of the copper wires inside the ribbon to break (even just on the inside). If it only works in one position or the other, it woudl be because the 2 end peices get contact then... the ribbon could ahve gotten caught or pinched or something, and that would do this.... Just my opnion...
Even i started facing the same problem. the phone would loose network connectivity and would take few minutes to catch it back. sometimes it would give me SIM CARD missing error. i had to restart the phone to make the SIM CARD detect, but most of the times it would not detect. on slide opening the screen the SIM CARD would get detected 1 out of 50 times. later i gave the phone for HTC authorized service center over there the technician narrowed down the problem to a damaged flex cable which connects the SIM CARD module to the motherboard. will be getting my TILT back from service tomorrow. . will get back tomorrow with the results...
I have this problem too ... but not just when shut.
It's permanent now.
hey guys.... i had the same problem too... after a couple minutes use the sim would " not be detected.." all i did was took a little sticky note and folded it a couple time to make it the size of the sim card.. then i ripped half of it off... then i opened the sim hatch and slid the paper in between the sim and the little silver bracket that holds the sim in...
it seemed to have put more pressure don on the sim so the contacts touch better i suppose... i did this a month ago and have not had a single little problem since.. might be an easy fix for some of you.. .. hope i heled : )
Update
mukhunthan did you have an update? I am wondering if I should buy a SIM card socket (found it for 50 bucks) or a broken parts tilt off ebay so I also have backup parts but could run into the same problem... Also, if it is not the SIM socket then I would be out 50 bucks. Does anyone have any opinions?

same fix worked for me
update:
bought a brand new SIM card socket and replaced. Turned on the phone, and while it seemed promising, the same thing happened. I have officially given up and want to through the phone across the room (lol) Have tried everything now from the paper to cleaning contacts, a new socket, new SIM, checking connections, ect. I guess I will be calling this one problem a failure. Now I have just purchased a used one off Ebay so I can have the busted one for spare parts (LCD, speaker, styli', batteries, housing, ect).
Thank you all for your input
hi....here is the update.. Got my phone back from the service center with a replaced SIM CARD Flex. It is working now perfectly.
I have the same exact problem like everyone else. The sim just shuts down when I slide it shut.
I was able to get a cheap replacement Tilt via CL, but my new replacement has horrible reception compared to my old one.
I checked around on the site, and now it looks like I will have to flash my radio to get a better reception.
If anyone has any tips for a first timer, please PM me.
Thanks!

Try upgrading the radio . U may use 1.70.09.01 radio. As far my experience it provides decent signal and also better battery life.
Try upgrading the radio . U may use 1.70.09.01 radio. As far my experience it provides decent signal and also better battery life. After upgrading the flex my phone started acting weird, call would get connected and on audio on ear piece. later upgrading the radio solved the issue.....
Same here
I have the same issue with my tilt.
I have disassembled it and found out that the main flex cable is damaged.
I have bought one at ebay and currently waiting for delivery.
People, as the sim card socket and it's flex are not moving parts, there's no chance it being damaged. The problem is in the main flex cable that connects the mobo and LCD unit.
My damaged flex shows about 5 lines that are damaged, they are cut off.
PS with this problem the microSD slot is also unavailable.
The phone lits up upon inserting the SD but it wont show up in storage.
I wish U luck.
But be sure that I'm right
I'm having the same problem as well... I'm going to try the sticky note procedure and really hope it works. I can't afford to spend $50 on a used phone :'(
has anyone come up with something new? ive just had the same problem, and here in mexico i dont think there are any htc centers...so im pretty much depending on u guys! pleeeeeeeeease lol
have any of you tried a new sim in it as i have found that the sim warp slightly with heat from the phone. I had this problem a while back and simply slightly bent the sim flat again and pushed the two metal runners down slightly to make better contact. Worked for me
i have had no problems before, i flashed a couple roms in it before, but in the end, i kept very lightly modded rom very close to OEM rom for the tilt that i got from here. all was well for months and months.. until now.
i noticed that the phone will lose signal. and not detect a sim card anymore. at first i thought it was sim. so i tried it on my other tilt (i have 2) and i determined that its the phone.
if i restart it, it works for about 1 min or less if im lucky.. then i have to to go comm. manager, turn off phone signal, and turn it back on, usually, that does the trick. but now, that wont even work anymore.
the only way to get the sim recognized again is if i slide the phone out, go to comm. manager, turn off phone and turn back on, and LEAVE the phone slided out. once i slide the phone back in, it will not detect the sim. ive tried diff. spl, different roms, and searched before i came back here.
ive had it for over a year, have broken the screen and messed up keyboard by closing hood of my car on it,
but ive fixed it. and that was long ago. maybe this new problem is because of this. if someone had similar problems, let me know what you did. or if anyone can point me into the next direction. i guess ill have to crack it open again.
I had a similiar issue where my phone would turn on ok, then lose signal and then get the no sim card error (dialer screen). What I ended up doing was taking a piece of tape and put it on the back of the sim card then slid it into the holder and locked it. (It was a thick metal tape, if you use scotch tape I recommend using a few pieces). Once I did that I havent had another problem with it. Its a pain to get the sim out of the phone because it ruins the tape but I would rather deal with that than not have my phone work correctly.
Let me know if that works for ya.
Jim
i see. so it seems that your problem was that the sim shifted out of place sometimes... i will try that. hope it works. its so odd that my sim card dissapears when i close my tilt
I just recently had a similar problem and I finally figured out it was a bad contact with the SIM card. you can either use the tape trick, or if you have a steady hand, take a thin object (such as a paper clip or glasses screwdriver) and very gently lift the contacts up underneath of where the sim card goes. they may have been pushed down due to abnormal pressure exerted on the back of your phone, I think that's what happened to mine.
thanks for your help. the sim contact issue was the first thing i suspected, AND tried. i used a needle. i raised the level of each of the 8 contacts making sure the sim will make contact with each pin. but the problem remains.
i will try this again. to double check. i will respond with the results
i tried pushing the pins up a little bit again, i still have the same problem
*but now i have an update, it seems that the sim card stops being detected right before i actually fully slide the phone back in. for examplle, before the slide-in tone is played, and before the screen tilts back.
i already took it apart for a look inside, everything seems fine. and i dnt really know wht to look for.
Hi,
was reading about ur issue, just tought on jumping into the wagon, I suspect it might be the flex cable that connects the sim to the motherboard, if there is such cable, i haven't opened my kaiser yet but my Pioneer car radio has this flex cable issue when the drive is closed the screen turns on and the whole radio but as soon as you press eject (the face will scroll and unveil the cd slot) the radio actually turns off and i have to move the face back to its original position in order to work. At the end I took the flex cable out and 1/4 of it was teared, in the end I had to order a new part
thanks so much for your help. i guess there is nothing left to do but to take it all apart. somewhat blindly. at least i know what to look for. bad cables, contacts... im clueless as to whether it can be a bad grounding issue? or a short. i dnt know. i guess i may be the first one to experience a problem like this on a tilt.
so i will do my best to get this problem resolved. and maybe include some pictures if it is intereting enough
my tilt totally stopped recognizing the sim.. it first happened when i dropped it and had to keep it open to keep contact.. then i was sitting with it open and tilted up, it fell and closed somehow and now the sim isnt there at all... i guess something is disconnected or whatever, im afraid to take it apart, but its either that or a paper weight.
New Sim
I had a similar problem. My sim card would disappear on occasion then one day I woke up and no phone. Just an annoying sim card not installed message. Checked the phone by putting in a known working sim card and it was fine. Called ATT for a new sim card and now my phone is working. Try a new SIM CARD.
For the original poster -- that fact that it works when the keyboard is in one position but not the other indicates that it is likely a bad flex cable.
Agreed
Its most likely the cable. I used a new SIM, the extra pressure trick, cleaned contact, etc on mine yesterday, but the problem remained.
I got a used Tilt from Craigsliist , reusing the SIM and case, and it works great.
i wonder if anyone has bought this item before and if it works? upon research, i think our problem comes from the sim card flex and ribbon:
http://cgi.ebay.com/HTC-TyTN-II-P45...AU_MobilePhoneAccessories?hash=item2a05bd88c4
It definitely comes form that ...but the repair cost is more than the replacement cost..so why bother with repairing it?
Hey, I'm having the same problem, my phone just out of the blue after a year of use says no sim card. My card is fine in other phones, and no cards work in my phone. I tried the pressure thing and cleaning the pins, but no good. My next option will be a hard reset/ wipe the phone and see if that clears the problem. I'm not optimistic after reading the thread. Did any one have luck with one of those Kaiser Flex Sim Card Slot Repair Parts that loller90278 mentioned? If so, I would rather spend $16 to fix a phone that has worked well up till now, rather than spend $100 on an unknown used phone. Still I don't want to bother if it's not going to work.
Thanks
well well...i'm going to have to join this "club" of affected kaiser users
my kaiser just started misbehaving last night. i bought it brand new exactly 1 year and 11 months ago
i took good care of it, barely ever tilted the screen during my almost 2 years of use. the current behavior is that when the keyboard is closed, the sim is hardly ever detected (1 out of 10 times perhaps). when the keyboard is opened, the sim is fairly regularly detected (9 out of 10 times perhaps).
i am not going to bother with investigating the possibility of a software problem because of my observations. given all the threads i've read about this issue, i am convinced my sim flex cable is either loose and/or broken.
anyway, it seems the kaiser's flex cable is just not built to last much longer than 2 years. if i can have it repaired for up to around $50, i'll go for it...if not, HD2 here i come!

just wanted to follow up on my own post above.
i just got my kaiser back. its been repaired
the dude cannibalized the main flex cable and sim assembly from a tilt and transplanted it into my tytn2. BUT! there has been an interesting side effect...because the tilt does not have a front cam, my guess is that its flex cable is unable to carry the signal of the front cam in the tytn2. so now my front cam is no longer detected. the camera app shows no icon to switch to another camera. the icon is blank!
i figured i could either have a kaiser with sim problems or a working kaiser with no front cam. i chose to keep the flex cable from the tilt because there is no 3G in my region and i hardly ever used the front camera otherwise.
long story short, my kaiser is back in business!
Similar problem !!!
Hello mate, .,. the problem in you case is the connecting ribbon between the keyboard that holds the sim card beneath it and the screen. I recommend u to replace the ribbon that connects. Its around 40 USD and that should do the trick.
Cheers !!!!!
HI,
My HD7 keeps resetting itself at random times and its driving me insane. I have tried different apps to see if its that and no joy, new case to stop the chance of overheating its happened about 20 times in the last 4 months. My question is would replacing the motherboard help and if so where would I learn how to do this? I have changed the screen already so I would be willing to take it apart.
Thanks
It's absolutely a possibility that it could be due to a faulty hardware issue. The problem is that there are many reasons that can cause the device to randomly reboot.
Anything from -
Software - apps/XAP's, tweaks, registry changes, WiFi, OS version and radio version
Hardware - Faulty motherboard, SD card, worn parts and broken/damaged soldering joints.
Was the problem with the device rebooting present before or after you changed the screen? If the problem wasn't present until after you changed the screen then it's possible that there is a bad connection of some sort in the device.
Also what OS version is the device on and are you running a custom rom on it?
The actually disassembly shouldn't be much different from when you replaced the screen other than you have to separate the motherboard.
If you've exhausted all other possibilities and are pretty sure it's the motherboard and want to change it take a look a this thread and there is another external link in the thread too -
http://forum.xda-developers.com/showthread.php?t=1585872
Here's a video that will give you an idea on the disassembly -
http://m.youtube.com/#/watch?v=4UBCFsMDTGA&desktop_uri=/watch?v=4UBCFsMDTGA
Ok thanks, so I had the phone from new, unlocked but using the 3 network. It started before I had even dropped the screen and put a custom rom in it, I was in a very hot country when it started so it might be slight heat damage. I have looked at the links and have now added them to my favourites. Although there is no direct link to a complete ribbon breakdown I am sure I can do it. Thank you for your help and once I have tried all aspects I will report back thanks.
Like me
I used the phone without the SIM card, no reboots or locks and reboots.
I'm using SIMs from a carriers using 850MHZ and 900MHZ all gave me reboots and locks, before the "solution" I used a 1900MHZ SIM with no problems (??? weird!!!)
Since the solution, I use my SIM without problem,
What I did:
1- Take the SD card and format it with sector check (long format) to see if there's a problem there, also give me manufacturer, capacity and class, if the card has it. Mine is a Sandisk 16GB Class 4
2- Raise a little the antenna connectors (2 copper fins near the sd card), BEWARE!!! they are FRAGILE!! if you break them (like me), you'll have to get some copper fins and use soldering iron (like me).
Believe me, I'm using my HD7 with no problem since then...
any question, here I am...
I have the sam reset problem but in one way. Yust if i use a Data connection to go on web. After random time, my HD7 start to restart itself. No warming or something else (mean overheat) of a phone.
What it could be? I am desperated
P.S. Problem starts when i am bricked my phone and went to "service" to do a JTAG flashing of it.
At first time after JTAG my phone warming up at a bottom of a phone (where an sd card settled and antena) ans start to reboot after Data connection enabled. After my complain to service they opened them again and told me there are all clean inside and after that my HD7 not wrming up but stil random reset after Data connection on web (HSPA+).
Any advice please or to throw my HD7 in garbage .
thx

I bought a galaxy note n7000 from a friend. It has android 4.1.2 installed. build number is n7000XXLSA.
the problem is wi fi doest turn on.I mean whenever i want to switch it on it seems its trying to get on but fails. The green light never shines on it.
The problem i cant understand lies with hardware or software.
Sometimes the wifi gets connected and then it works like a charm. But most of the times no matter how hard i try it never gets turned on. Ive tried factory reset, restart, removing batter and memory card nothing seems to work. I tried wifi fixer app but nothing happened.
I am not very technically aware of rooting, and how to modify it. But i think from what ive learnt is it is caused by updating from ICS to jelly bean 4.1.2
I dont know whether my phone is locked or unlocked, rooted or un rooted cause im totally new with phone.
Please someone guide me how can i rectify this problem, I dont mind taking risk with my phone but wanna know what all should i do to solve wifi issues.
Plus i also would like to update to 4.2.2 kindly let me know step by step starting from basics how should i go about it.
regards
Go to settings and wi-fi and there when you turn on the wi-fi it should show the your network which is remembered and show read something as authenticating obtaining ip addreas and such.. Just select your netwirk once and click on forget and then try to connect again putting in your network key.. To check if you are rooted or not: you must have an app which saya superuser or su.. You can also download root checker app from market to see if you are rooted or not..

I suggest you move on to stunner rom instead. It has all the features of the Rom you are currently using. Stunner is, if I've got it right, built from parts of PA.

Solution found
sorry for the long post but this will work
After three months of dealing with the same problem on my GT N7000 as nashbloom i have found a fix to this wi fi problem.
And I mean WIFI problem. this is not a matter of obtaining a connection, this is a problem where the wifi wont switch on at all.
It trys, to switch on (sort of transition phase) than freezes or fails and turns off again.
Just as I was preparing to back up my phone and take it in to samsung the next day I found a post on a you tube clip saying to clean corrosion built up on wi fi antenna.
Desperate, I tried it,
1. remove 9 screws (dont worry they are all the same size) on back and remove cover
2. with a cotton tip/bud wipe corrosion in top left hand corner (looking at the back of the phone)
3. not knowing what a wifi antenna looks like and having seen no corrosion i wiped everything including the cover.
4. i removed a few connectors and put them back in place.
5. put everything back in place and problem was instantly fixed
I did this two days ago but have had one time where the same problem reoccured, otherwise, perfect.
P.S. This is proof that this is a hardware problem not a software one, but i kind of knew that when i changed every wifi setting on the phone several times
will try these today
I will try these today as soon i get home.. i been looking around for a fix.. I hope these will resolve it

Two months now with this silly wifi issue. Did this trick help with your phone?
I did everything possible trying to solve this problem but to no avail.
Wiped anything that could be wiped on the inside, replaced the USB port board, but wifi is relentlessly disconnecting at random times.
Any idea?

I found something weird.. when the phone is without the back cover wifi works perfect. when I put it back the wifi goes off. ???? I really do not know was wrong with the phone.. (i do not use it anymore).. the only guess is that the back cover pressure something to the board and disconnect the wifi.. I really do not have a explanation.. take care..

Like everyone here, I was having the problem with the greyed out WiFi and also got some practice with flashing firmwares and doing factory resets, backups and restores, all in vane.
I found this post and decided to give it a try, also checking a YouTube video about how to open the GT-N7000
My phone did not have any corrosion, but after reconnecting, i.e. taking out and plugging in again, all connectors to the main board, the WiFi came back to life. That was two days ago. I cannot say it works like a charm, after a couple of hiccups, I just don't trust this phone anymore and I think I had the greyed icon once yesterday when I tried to switch off and on the WiFi.
This experience led me to believe that there is something with the connectors that got loose after my phone has fallen off my pocket a couple of times. If you wear pants that were not designed to carry phablets, this might happen to you as well.
Anyway, a big THANK YOU to atchya for the idea of opening the phone.
Cheers,
[Possible solution]Follow the link how to clean up the connectors
Yeah above solution works. This Is the only way I got my wi-fi to work. Tried re-flashing Rom (downgraded and upgraded) even re-flashed Radio. Finally cleaned up , unconnected and reconnected cables, so far works fine (no greying out of menus etc.) . Will keep you posed
edit: Open the photos in different tabs to see the antenna connectors, they are tagged you will know exactly what to clean
Starting yesterday, I've been getting a popup that says "sd card unexpectedly removed" on my incredible s (stock 4.0.4, sense 3.6) even though I haven't taken the card out. I've found that this is only when putting the back cover of the phone on, it works fine with the cover off. I've tried reformatting both on the phone and on a computer, and the card works fine copying data between my two computers and even another phone. Any idea as to whats going on? It doesn't make sense that it's a bad card because it works fine everywhere else.
maybe try reset to factory defaults your phone, in my case after reset it works fine

If you try your card plug to PC via cardreader? Maybe try copy all data from card to pc and format it?
I tried formatting on my pc multiple times and it still isn't working. Interestingly enough it worked for a day or two and just started up again

SD Card Errors
I have the same sd card problem on HTC incredible S for months. I remember seeing someone suggest lifting the two pins up a bit at the back of the phone. I tried all four pins that I can see that but still not successful. Before S-off and after S-off, also see the issue.Tried different ROMS, VivoKat, Revolution-HD, also not successful. Flashed my radio to the current version, also see the same issue.
If I do not closed the back cover of the phone, it did not removed the sd card, though the signal strength for the radio drops drastically.
What are the pins at the back of the phone meant for? When we put on the back cover, aren't we shorting (1) shorting the pins at the side of the rear camera, (2) shorting the pins at the bottom near the sd card. Or should they be shorted?
What is the function of the phone back cover? Ground Plane? Attenna and/or sd card on/off switch? Is there something we need to do to the back cover for the sd card to function properly? Or is it shorting the SD card that forces it to eject? Should we snip away the plastic metalized pins at the back and solder a short wire shorting the pins? Maybe one pin must touch the back cover while the other one should not?
At this moment, I still cannot differentiate whether it is a hardware/software/firmware issue. Any help is appreciated.

Think I figure out but need other people to confirm the method.
1. The two pins at the bottom near the sd card is meant for antenna, putting the back cover on will increased the signal strength, so they must contact.
2. Put a piece of paper on top of the two pins next to the rear camera before putting the back cover on. This will block the pins and prevent them shorting with the back cover, thus preventing the sd card from being removed. Well, I still do not know the function of these top two pins. It may be meant for detecting shock when the phone hits against something.
It has been hours and still the sd card is functioning well. I think this will solve the mystery for many people.
Hope it helps.
My Bad. The method does not work. SD card issue again.
Probably irrelevant, but I had the above SD issues for a while – like you say *intermittently*, though I also had a few other software anomalies which is why I decided to flash a custom rom; I thought, what the hell?! Anyhow, swapping the card between a couple of phones prior the flash – it still did it, so I thought, cleary the card is stuffed – but after GoldCarding and getting #6 ‘I think it was’ running, it never [well, so far] did it again…Good luck with it, cheers Dyr

I'm not sure, but I suppose those pins are the WiFi antenna and the other pair it the GSM antenna. All of them sould have contact with the back cover. Poor antenna means higher transmit power and more battery drain.
I had this SD card issue once. I think i just wiped clean the contact points on the SD card and it never occoured to me again..
same sd card intermittently removed problem after factory reset
I couldn't find any solution for this problem.
my assumptions were defect on card slot but there is no any issue of hardware.
drastically signal strenght drop and Sd card defect problem stil exist. any suggestion do you have.
thanks foryour valuable suggestions.
