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.

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
So I just bought myself a "new" 8925 off ebay, and what a surprise, its busted. To be more specific, it wont charge when plugged in (I tried multiple chargers, and a different battery, it is definitely the phone). Also, it doesn't recognize that my sim card is inserted. To top it off, some of the keys on the keyboard don't work properly, they require significantly more pressure to register than others. My question is this, is there anything I can to fix these problems myself? I've opened up my 8525 to change out a screen, so I'm confident I could reassemble this guy too.
Any advice would be greatly appreciated
I guess I'm one of the unlucky ones who has to send this phone in for repair.
Going there this morning..
My question is to those that have received their phones back. Any indication that the repair done has anything done different to the phone?
I mean, if they are just replacing the defective guts with essentially the exact same guts but working, does that not mean it will just happen again (SD Failure)?
Or did they actually change something within the phone to make it more durable and essentially eliminate what brought it to them in the first place?
Hopefully someone in the know could answer this... pointless to repair something with another soon to fail board or sd card.
that is a very good question, of all the phones i sent in for repair and got back
they kept their original IMEI numbers
they all came back with replaced PCB (motherboard) and cause of failure is "No Power"
by that i figure out they mean, it does not charge when you plug in the USB cable to the phone after it dies.
it seems like whatever controls the internalSD also controls the USB charging of the phone
so the problem might not really be with the internal SD but rather the power relay that supplies power to the internal SD and battery charge.

This is a great point allgamer.
However fact still remains... if they are swapping out the guts for identical, but working internals, that defeats the purpose of actually correcting the problem as the problem will surely pop up again.
Lets hope it doesnt.. but this phone doesn't seem like a good candidate for constant flashing the way my old HTC Touch Diamond was. Especially if you're doing it with ODIN, you may not have a leg to stand on come out of warranty claims.
At least if you flash something with KIES, because it was an "official" update provided by samsung. So if the phone goes corrupt, you can yell to the heavens and they'd have to fix it, because essentially they corrupted your phone.
It would be great to get some feedback from other members who received their phone back from repair. I wonder if one of those members had the SD go corrupt again with the new Motherboard in place.
I have been trying to repair this phone, but the usual faults have not turned out to be the problem. This is the background on the repair efforts:
In my research I found 3 main causes for a dead touch screen.
1) Corruption of system software.
2) Failure of digitizer cable (hinge FPC)
3) Failure of digitizer screen (touch panel)
To check for #1, I flashed the firmware again (after a wipe). I downgraded to Android 1.5 because I wanted to root the phone and install CyanogenMod Android 2.2 Froyo.
This was a big mistake because I learned that when you don't have a working touch screen, you cannot get past the "Touch the Android to Start" screen.
So on to step 2 - replace cable (hinge FPC). I have a G1 parts phone that was lightly used in good condition before it was damaged. There was no damage to the sliding section, so I expected the hinge FPC to be in good condition.
So I installed the hinge assembly with its hinge FPC from the parts phone, but this did not work either.
So next I installed a new touch panel (digitizer screen), but that did not fix the problem either.
I had a chance to borrow a working G1 motherboard, and I was surprised to see that the phone was working with the borrowed motherboard.
So my question is whether my problem motherboard can be recovered with a software solution, or if these symptoms indicate a hardware failure.
I thought that a wipe followed by firmware flash would eliminate all soft system errors, but I am not sure if the wipe and flash really erase absolutely everything, or if there is something else I need to do to get it working again.
Thanks.
more than likly it was the point in the motherboard where the flex cable connects. try using some electronic parts cleaner.
i have ran into this a few times and simply replacing the motherboard has only helped a twice, when i cleaned it up it worked.
That sounds reasonable. I still have some Tweek. I'll give that a try. It worked with the same kinds of problems on computer sockets.
Okay. You are on the right track. When I went back to the phone, I actually got two taps out of the screen, which it hasn't done in a long, long time. (I was running keyboard only for a long time before I could take it down to fix it.) I attribute that to just disturbing the contacts with so many assembly/disassembly efforts.
After I applied Tweek to the joints, it ran well.... for about an hour. Trying again was no luck, so I don't think I'm going to mess with the contacts anymore. By the time you figure how infrequently motherboards come up for sale and the cost, I think I'd do just as well with a trade in on a flat-rate repair.
But at least now we know for the record that there is another cause of dead touch screens.
well i have about 13 motherboards, if your interested let me know
Thanks. What has been your experience with changing motherboards?
The reason I ask is because the service manual wants the phone to be tuned again after a motherboard swap. I see a lot of people changing motherboards, and I can't believe that is much of a problem when you don't see anyone complaining about the phone not working well afterwards.
A spare motherboard might be a good idea for a diagnostic tool. It would have saved me a lot of work changing the touch panel and cables if I would have had a motherboard to try first.
I thought I had a good spare in a damaged phone, but when I took it out the other day to test this phone, I found out it had physical damage too. The SIM holder and RF shielding were dented, but the killer was that the daughterboard cable connector was bent.
I suppose back when the phones were $900 you might try to fix something like that, but it's hard enough to do a connector swap on a computer motherboard. I can't imagine that even the factory has the equipment to properly swap the connector even if you can get the part.
How much do you want for a motherboard? On that famous auction site I've seen them go for around $10 to $30. I could kick myself for not buying the last one I saw at $7 because I thought I had a spare.
Hi all, I hope someone can help.
I recently encountered a Bluetooth issue, where the signal strength was very weak when using multiple pairs of headphones. I downloaded a BT signal strength app and using this, I found the strength hovered around 30-40%. Having had my screen replaced previously by a local repair shop, I suspected there was a loose antenna, so I opened the phone to find damage to the motherboard, whereby a small piece of the board was completely missing.
I then purchased a used motherboard from eBay which I then fitted. However on powering up the phone, all I got was the Huawei logo on black start up screen then it turned off. With charger connected it would continuosly bootloop. I then done factory reset and restarted the phone and after a few failed boot ups,it eventually powered up. It was locked with the screen lock from previous owner, which they were happy enough to supply. With the phone unlocked I then set about setting the phone up using my own Google account and all seemed fine. Every aspect of the software/hardware appeared to working perfectly.
I then updated to emui12 which appeared to download and install, however the phone went back into the previous state,whereby it turns off after the Huawei logo appears.
I have no file available in eRecovery. If I put my old damaged motherboard back in the phone boots up first time. I would at this point have given up and reverted back to my old motherboard, however when taking it out,the upper microphone has broken clean off the board.
Any advice out there?
Thanks in advance
Update, which may help anyone in the same position.
It appears the motherboard is paired to the battery and the boot loop issue was resolved when I used the battery from the donor phone I took the motherboard from. I assume buying a new battery would have been another solution had I no access to the battery which was paired to the motherboard I used.
