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 !!!!!
Ok guys I had been without my phone for about 2 weeks due to it not detecting the sim card. After replacing the sim card, as well as the slot and many other parts, I thought the only remedy to fix my phone was by replacing the main board. Through research and having the additional sim slot by my side, I came up with a great idea that finally worked! This is what I did. First, open the sim slot door and locate a tiny black switch, this is the one that is controlled by the switch on the outside. Push it up all the way and power up the phone. Hold press firmly on the sim card against the phone, with the outside door open. Wait for the phone to boot up and the green light to flash, which means it is getting a signal, then you can release your grip and close the door by locking it. Everytime you reset the phone you will have to follow this procedure, but at least the phone will work. I am thankful that I came up with this idea because it saved me from having to buy a new phone. I believe the problem is that the outside switch is not fully catching the inside one, which is why the sim isn't being detected. Hopefully this resolves everyone's problems, because it sure worked for me! Let me know if you have any more problems.
Wow no responses? After all the problems people were having with sim detection? Please post feedback because I was curious if this worked for others as well. Thanks.
id help u out but i had 2 tilts and just fixed this problem of mine today, i just changed the part of the phone with the sim card holder on it and it works perfect.
Awesome!!!!!!!!!!!!
I have had an AT&T Tilt for about 6 months with this problem, i just read your post today and that totally fixed my problem, thank you so much!!!!!! Although in the down time of the one Tilt I purchased another one from a friend, oh well now i have two working Tilts, thanks again!!!
worked for me
i just have a small square of cardboard stuck to my sim, then the door pushes the sim against the contacts, but same idea as yours really. but this problem started for me when i replaced a smashed screen so i had assumed i shifted everything a little in the process of putting it back together.
works
i tried your method and that better than holding that door, thanks for the suggestion!!!
Glad to hear it has worked for you guys.
Lifesaver
Flashed a buddy's phone tonight. Spent three hours trying to get his phone to read his SIM. Found this thread and your advice worked like a charm. Thanks
No problem. Glad to help. I just wanted to help all the people who were having this problem so they didn't have to deal with what I had to deal with and be without their phone for 2 weeks!
Fantastic this Worked!!!!
This worked straight away. You ought to be congratulated. Ingenious. All these other threads I checked couldn’t find the solution. They talked of dry magnetic head spray cleaner, deoxidizing boards, flashing the phone etc. With some saying success after a few goes. Its kind of funny that what might have been happening for them, is that constant opening & closing the simm card cover in their processes probably inadvertently fixed prob by pushing switch in enough. Whereas your solution goes straight to the problem & solves it. Hilarious. Thanks Heaps Tilt Fanatic. Nice to have my TYTN II back up.

hi guys,
i got HTC tytnII/kaisser over a year ago,
and now i got this problem "sim card is missing",
i tried to put some paper and it didnt work,
try anything in this forum and it didnt work...
almost frustrated and thinking of put it on a cupboard.
anyone have another solution?
thank you
I don't know what caused this.
I got my G1 today. It worked for probably 2-3 hours perfectly fine.
I had an app freeze (either Barcode Scanner or Lock 2.0) and had to do a full hard reset.
Now, whenever the phones screen darkens or I put it to sleep manually, it WILL NOT come back up.
I have factory reset three times now to try and get this to work.
When the screen is black, all buttons on the phone still light up and so does the LED indicator up top. I had my phone set to use a locking pattern screen at one point during one reset to test out and when the screen went black, I was still able to try and log in by doing my pattern. It unlocked, but still showed nothing on the screen.
Please help!
I've tried:
Turning Wi-Fi off
Turning 3g Off
Disclaimer: Yes, I've searched. I can find other users with the same problem but none of them seem to have a solution.
Phone is NOT ROOTED and has the factory ROM.
Update 1: Update: It only freezes/blacks out when I try to wake the phone from one of the front key buttons.
If I'm sliding to unlock, it seems to be fine.... (but if I've already tried to open from the front it doesnt)
Update 2: If I mash all the buttons in random orders for about a minute or two it seems to come back. Anyone have any idea?
Update 3: I'm thinking this has to be an issue with none of the buttons waking the phone up when closed. If I lock the phone with the "END" key, and then click the front "END" Key again, nothing happens. If I slide the phone open, and click it twice - the phone wakes up.
Update 4: Confirmed update 3. Phone will not unlock via front keys unless it's slid open (or open enough to trigger).
I would really, really appreciate help with this.
Hate to bump this, but I've added some detail on the top and bottom. Have to leave for work, hopefully someone might have an idea by the time I get back.
Well you can try to reload the factory rom or root it and try a custom rom and see if the problem still exist. If it is still happening then it would be a hardware problem and need to be sent in. And yes you will still be covered under warranty with HTC since the phone is still less than a year old.
I had a problem with exactly the same symptoms. It turned out that the SD card was cocked-up so home, core, and some other process would hang trying to read it and the phone would not wake-up the screen any more.
Did you try removing the SD card and seeing if that helps?

Removed the SD card and rebooted the phone.
No change ( still acts the same way ).
Did you factory reset after or was it an instant change?
I don't mind losing data to fix this.

Wouldn't I have to root to reload the factory rom? Is there a rooting tutorial based just on that?

If you use the official update you don't have to have root. There are some links on here. I'll see if I can find it for you.
https://android.clients.google.com/updates/signed-gfh-CRB43-from-CRB21.c88b03d2.zip
That should be it, but can't confirm since I'm on my work computer.
Some thoughts--may be useful, or not:
Mine was doing that too, but it was caused because I dunked mine underwater during an urban exploring mission. I dried it out, replaced the LCD screen, and everything worked until it would go to sleep. Then I had to do a variety of button mashes and opening the keyboard to get it to come back to life. Sometimes it just wouldn't come back. The problem grew worse over time.
If wiping and reflashing (no need to use a stock ROM) gets you nowhere, then I would suspect a deeper hardware issue. I see you bought it used, can you contact the seller?
If you want to check for water damage, take out the battery and look at the tiny circular sticker in the battery chamber--if it is not white, it has been water damaged. (And the warranty will not be honored.)
Other Lesson: No urban exploring with G1s.
The link didn't work, btw.

Zero water damage.
That's great news zeabrid! In that case, I agree with an earlier poster--you should be covered by warranty. Wipe and flash a good rooted rom, and if that doesn't work, revert to stock and demand a new phone.

Do you have a link to a guide that teaches how to do this (with the stock rom)? I can only see a few that're spread out.
I'm not entirely sure my phone can boot into safe mode/disk mode, so we'll see about that.
Another update: When I boot into safe mode, the same problem exists.
Edit: Just emailed HTC.
This can officially no longer be considered a software issue.
I just rooted and installed a standard ROM. Same issue.
It happens all the way at boot now, just realized this.
HTC emailed me back and told me to call them directly. Will do that tomorrow.
if I find a solution I'll post it immediately.
Alright, my phone is officially ****ed.
Restored back to the original rom.
New problem now: When I close the screen, the backlight goes out and doesn't come back on. (I can still barely see everything, but there's no light).
Calling HTC today.
Edit: Called T-Mo support. They suggested deleting programs to free up space (I only have 2 downloaded and to reset (already done)
=(
Edit2: Called and placed a RMA with HTC after talking to two of their customer support reps. Thankfully, they forwarded me up the support tier after only about a minute with each person when they realized I had already tried all other steps.
The RMA process was surprisingly easy. I have everything set up, and when I get paid (tomorrow) I'm going to ship the phone out. I was given an estimation of 7-10 business days for full repair and return shipping (which sounds great in my opinion - I've never sent anything in for warranty work before).
I'll update you guys once I hear from their repair team on whether or not I'm going to be covered under warranty (I told them that the phone was a gift to me), and if not what the cost is going to be. Like I said earlier in the thread, all water damage indicators are clear and I have unrooted my phone, so I should be covered hopefully.
Thanks to anyone who posted in this thread.

Yea it defitenly sounds like a hardware issue and needs to be fixed. Glad your getting it fixed and you'll be covered no problem.
Do you know if they charge return shipping if it's covered under warranty? I have to pay my own shipping there, and they had me put a credit card down on file in case I either bail when its already there or they need to charge for repair.

To be honest I don't know the answer but would like to say they would pay for it. But they would have to let you know of the charge before they apply a charge to a credit card.
wow its weird cause im just having a similiar issue now.. in landscape mode.. phone and back light work perfectly. but one i close the screen everything goes virtually blank, everything is running perfectly just the screen light wont turn on..
will try some of your previous methods.. hopefully it works on mine..=/

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..

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
Hello all,
I've been using my MI 11 ultra with the Xiaomi.eu latest stable version for months and never had any issue. Today, I was making a videocall on Whatsapp, and after hanging up the phone, the screen just turned black and never came back.
I tried to reboot on fastbook/recovery, but seems like the screen is just dead. Things that I tried.
- Plug in the phone charger (nothing happens)
- Force restart phone by holding the power button (It makes a little vibration like it's rebooting, but nothing happens after this)
- If I connect my phone to my laptop, it detects the phone as MTP, but I can't do anything with it.
- I tried to list device through ADB, but I doesn't appear in the list.
I have no clue what to do, at the moment it died, I wasn't doing anything special, I thought It would be because of the heat, but the phone wasn't hot.
It's really weird. Is there anything else I can do? Am I missing something?
Thank you in advance!
I think it's time to take your phone to service center...

Agreed!!!
has anyone sent the phone back to china for screen repair during the warranty period? Wonder how the process works.
Warranty with Eu. rom?! highly doubtful.
if you can fastboot your device, i'd suggest that you install original rom. (DONT LOCK BOOTLOADER). then jump to fastboot again and lock your bootloader. then send it for warranty. I don't think you'll need the screen to do that.
dont worry about device access and boot inside, doesnt matter.
Thank you all for the answers.
I stil have my last breath of hope, I found someone who had a similar issue with an Mi 11 => https://xiaomi.eu/community/threads/black-screen-on-mi-11-ultra.63498/
I wasn't expecting it for this phone, you never expect this kind of weird issue from a 1k phone hahaha. It never happened to me and I've been flashing my Xiaomi devices since 2010
I'll try one last time, the back screen is not responding neither and as far as i know, they have different video controllers and since my computer can recognize it, I still have some hope.
This issue got me on vacation in the middle of the rain forest, and as you can imagen, internet here goes really slow.
I'm trying to download all the stuff that I need and once i have it, I'll try to restore my phone. I'll update you all with the results
Thanks in advance!
that would be great because if one of us should have the same problem then he can look in here and help himself
Hey all,
After fastboot, nothing changed unfortunately, I think I'll need to send it to warranty.
thank you all for the help

I had similar problems on my samsung galaxy a12. I flashed older fimware and the screen would just not work, it would be pitch black 24/7 no matter what I have done. I had to blindly enter in to odin_mode and flash new fimware. Similar thing is for you, try blindly booting in to fastboot or what ever you and flash the orginal ROM and don't use EU one because they probably wount accept it with in the warranty. AND UNDER NO CONDITION, DO NOT RE-LOCK THE BOOTLOADER
Hello all,
I have fresh, happy and weird update!
I was decided to send my phone to service center, I was just waiting to come back to Spain from my vacation, meantime, my phone was between my clothes since my last update.
Today I took it again while I was packing my things and voila! Screen is working again
My guess is that after taking a heavy rain, it got wet somehow (I say this because it supposed to be waterproof) and this caused the screen issue (3 days after the my rainy day).
Leaving the phone between my clothes, it my helped to dry out any water that could have leaked inside and phone is working again.
So, what I learned from this experience, never trust the waterproof certificate, hahahha.
I think once I'm back home, I'll put the phone on the water and try make the issue happen again, then send it to the SAT.
Thank you all!

Warranty doesn't cover water damage as far as I know
You might be safer not trying to repeat the experiment
