My HTC Universal says the SIM Card cannot be found or is missing, which of course is not true. I have tried with several SIM-Cards, but none of them work better. The error message appears as follows: Sometimes the phone connects to the network, but then suddenly the connection is cut off.
I bought a second-hand device, but before I jump to any conclusions I would like to rule out whether:
-it could be related to a radio upgrade
-it could be related to the SIM-Lock removal
-it could be related to a ROM-Upgrade
I am using Radio 1.18 and maxstegi's ROM 4.7.
Besides, I would like to know where to fix the device. It was originally a T-Mobile MDA Pro, but now that their software isn't any longer installed, they would probably refuse.
Thanks in advance

I had the same problem with mine. I eventually solved it by playing a hot-air rework blower over the radio chips, It's a bit of a drastic job, but it worked for me.

i had the same problem .. and i tried another solution .. i got a dry magnetic head spray cleaner and i sprayed the whole mother board connectors .. it worked as a start with me and i am waiting if it will remain good or will happen again ..
3 days now and my xda didn't give the sim card message - my problem solved
Great idea. I'll try today!
Sorry..but..for "dry", what do you mean? Is it the isopropyl alcohol based liquid?
i mean dry that it does not leave any traces on sprayed place after a while .. some other magnetic cleaner sprays leaves an oil layer over the sprayed area ..
ask in your location for a magnetic head spray cleaner and i am sure you can found one easily
it is now about 1 week and i had no problems
thanks

I also suffered with sim card problem and got the solutions please check your PMs, sent you the web address to download it, have used it myself, works good.

Hi aym_louis "big mind"!
Yesterday I immediately went to buy the spray "deoxide for contacts" instead of "magnetic heads cleaner". It was not the kind that also protect the contacts, so it doesn't leave the oil layer on them.
Well...I opened the mda pro, sprayed all over the motherboard and waited for 20 mins. I inserted the sim and didn't work....at first!
I tried after some more time, and it worked, and kept working 'till now...thing that never happened before! Maybe it needed more time to deoxidate the mysterious contacts.
Really good idea! You solved a big problem, in a easier and more secure way, compared to the hot hair flow!
Weeel done!
thanks dear .. any time

sorry .. didn't notice your PM . anyhow you've got your problem solved
Yes problem solved
Hey Guys,
I also have this problem for a long time and I'm using another device now..
to summarize:
1. I need a magnetic head cleaner? not contact cleaner?
2. Which chip should I spray? on which side of the MB?
3. Should I go the "hot air blower" route at all?
It's a really annoying problem!
Thanks,
Ariel

I've got the same problem, and I've tried yuor solution but it doesn't work for me.
I've used a dry magnetic head spray cleaner on the motherbord (front and back) but the problem is the same ..Sometimes SIM Card is missing..
I noticed that if the settings of the phone (Band) I force GSM (not Auto) error occurs less frequently..
any Idea?
It worked great!!!
Just tried the dry magnetic head cleaner spray and all I can say is it WORKED GREAT on my Uni, which was displaying that «Invalid or missing SIM card» annoying message!!!
I disassembled the unit completely (this included removing all the inner metallic "shields" fitted to both sides of the mainboard), sprayed the mainboard on both sides repeatedly and quite abundantly and allowed it to dry for an hour.
On the first reboots it kept getting stuck on the 1st splash screen, so I waited for another hour, for it do dry completely.
I then performed a hard reset on the Uni(t).
It simply worked. My SIM card is now recognized again.
I'm on my 4th reboot since I've reassembled it and the OS loads completely, I've reinstalled the software applications I lost after the hard reset and my SIM card keeps being recognized by the Uni and allowing me to make / receive phone calls & text messages.
Thanks a lot for the hint.

congratulation on your WORKING mobile
Hi Guys,
For what it's worth i have exactly the same problem on my G3 device. I used Servisol Video 40 from www.maplin.co.uk which is a tape head/disc drive cleaner, and it says on the can that it "removes tape oxides and dirt". I removed the shields around all the qualcomm chips and covered the MB, let it dry in sunlight (took 10 mins), reassembled and the problem is still exactly the same, i.e. this method DID NOT work.
For those of you who DID get this to work it would be very useful to know EXACTLY what cleaner you used.
It would also be helpful to know how 'permanent' the fix was, and if anyone else has tried what I have and succeeded or failed?
Many thanks for the helpful posts, if I can get this solution to work it would be awesome. If not then it's onto the rework station and who knows what then.
Cheers,
Appy
I am suffering from the exact same problem; can those of you who fixed this horrendous issue by spraying your motherboards, could you please confirm that your devices are still free of that "missing sim card" error. And what brand of spray did you guys use? If at all it makes a difference.
Thank you.
I cannot find anything in stores remotely similar to "dry magnetic heads cleaner spray" if you guys know the brand name of this product or an alternative, please post your replies.
Your help is greatly appreciated!
found contact/head cleaner at the source; sprayed once then tested, it didn't work. Sprayed second time then tested, it didn't work either but managed to keep the phone alive without loosing the sim for a few hours. I guess will be spraying the third time in a few days...
If anyone has any suggestions please feel free to share.
Hello everyone! I have problem with my phone because sometimes is turning off without any reason, I bought brand new battery and is still same when is switched off and I want to put it back on i must take off battery for couple of minutes, then put battery back and then switch on anybody know whats happened?? And how to fix it!!
It's the most standard problem with htc models touch and elf...
This problem is hardware based! in this condition there are only 2 things you can do:
1.send the device to a htc service center and get the motherboard changed for $300+ if you are out of warranty.
2.Or open the mobile and put a piece of thin plastic in between the omap prosessor chip and the steel piece tha goes over it and then put the second cover on top in order to apply pressure to it because the solder pins that are in between the cpu and the mobo are not connecting properly and lose contact so the phone goes off or freezes then goes off and some times stays off. Make sure that there is enough but not to much pressure applied to it! it worked for mine but i did it because it was out of warranty... its a temporary fix but if you are gentile to it after it will surely work for a few more months...
IF YOU HAVE NEVER DONE SOMETHING LIKE THIS BEFORE OR YOUR TOUCH/ELF IS STILL IN WARRANTY DO NOT TRY IT!
I will post a pic that i took when i did mine if anyone is interested... Let me know...
Thanks for reply!
Uff.... first way to fix it is a little bit too expensive! And 2 way to do it seems quite easy, so i try to do it this way Could you add any picture of this and just tell me how to open this phone?
Many thanks!
@Firestarter42
Thanks man!!!!
did what you said, the plastic trik, and the phone is back to life (it was totally dead and didn't charge) you save a life today!!!
I had the same problem untill one day when he didn`t want to turn on and now i do not know what to do with it how to make it work again
Dear Sir,
I have just tried method 2.
My elf didnt have a metal cover on the processor, lol... got it used from someone... or should I say abused? lol
anyway, I hope it works. will update...
here's a link for the demonstrated tutorial:

I haved the same problem.....and i realize after many times that I didn't change my ipl and uspl!!!so my cocked rom frequentely turn off my device!!!now it's all right!!!!!!!
i had the same problm too....
it kept turning off and just a few weeks ago it would never turn on...
i did try that trick of keeping the plastic thingy on the omap processor ... it worked for a few weeks max after tht it happened as above
finally took my phone to htc.. told them it was gift and i dont have the invoice... actually purchased frm ebay for 150$ .....
they checked it was in warranty,.. they replaced the board... hurray... my elfin is alive again.. and in wm6.1
hope htc fixes this crap issue as many face this problem
My HTC elf was freezing, rbooting and so on, i was thinking that it was a windows/flash/third party programs problems ....
BUT I confirm that the method "open the mobile and put a piece of thin plastic in between the omap prosessor chip and the steel piece tha goes over it"
brings my htc elf to life again ... stable !
(i've done it with a metal piece and not plastic.)
Thanks for the advice !!!!
my elf was freezing and turning off so i try this 2. method and it works, and elf is much faster then before in my case...
I've never had this problem before but this week my phone switched itself off (so had to boot up again) a couple of times. I did try a new custom rom but I've also been using a different charger (USB mains adaptor) and a replacement battery (this seems to be a poor replacement battery which seems to make up the battery level.
So I don't know what was causing it. For some reason, removing the SD card and re-inserting it seems to have done the trick for now but I'll keep watching it.
Hi guys
My phone is, usually at night when there is no use, switching the screen off, the earphone green indicator flashes but the phone will not turn on when I press the power button, I have to do a soft reset each time to get it back on again (even though it appears to be on with the flashing green light). I cannot get calls or text and my alarm fails to sound. Have overslept a few times now!. Also, its battery has gone for a ball of ^&*%. Will this trick help? Thanks a lot!
Turn off as in literally 'poof!' or, it will restart?
The only way to get it to restart is to do a soft reset, or remove and replace the battery. The phone's green light will flash but there is no way to the screen to activate or use the phone - make calls, use the alarm, receive etc. The screen stays black, no use trying the power button either...

power problem on Elf (not the usual)
hello guys, i have an Elf T-mobile that someone "lost" i found it, but was bricked...i unbricked following the awesome guides on the forum and installed on it the original italian rom (obviously am not german)
but...here's the problem, when i press the power button (should get it into stand by mode like every pda does) or also when goes on stand by itself, just shuts down !!!
then the pda auto soft resets, until the end...doesn't have the "auto power off problem" like i readed on the forums...however it tried but didn't solve the problem
i think is a problem with the radio, or the IPL or SPL (i tried 1.11.0002 IPL and 1.11.000 SPL...then 2.2x.xxxx IPL and SPL...now i tried 3.14.0002 IPL and 3.14.0000 SPL, also tried different radios...
but the problem remains...
EDIT: Problem solved, changed the little battery in the motherborad, it worked for me

I'm presuming you mean for option 2, as 1 is quite obvious
Anyways, I haven't done this, but I am posting my best guess (untried, untested, just a theory).
Open your phone up and completely dissamble as described here. Completely strip it down so you only have your mainboard. Clearly take all the necessary precautions before hand (backup, etc etc.)
When done, you will see there are blank shields above where the chips will be, if you look, you can see little dimples, you can ease these off here. This will get you into where the omap processor is. You can then put the plastic on top, and make sure it is done as described. Should literally be a case of putting it all together and hoping for the best after that. I will have a look at some point (can't promise when) and see if I can take some photos of where this will go etc.
An alternative would be to try and reflow the joints of solder with a heat gun... very dangerous considering how tight the components are packed in, and overkill.

where to get small battery on mother board
Hey guys,
The earpiece speaker on my G1 has developed a fault, the fault being it doesn't appear to work, how easy is it to source a replacement for it and how easy is the repair itself? is there any guides as to how to do it around? (i looked but i couldn't find anything).
I've tried flashing the rom and doing a hard reset but its still faulty.
The loud speakers working fine though so atm all my calls have to be done on the handsfree kit or via loudspeaker which can get annoying.
any help is much appreciated
regards
Streather
Are you using a ROM where sound works?
What ROM are you using?
Tried it with cynagen and the stock tmob one, same results.
Same problem
I'm using CyanogenMod 4.2.5. I dropped the phone about a foot (it fell out of my shirt pocket as I was tying my shoe!), and the earpiece stopped working. Everything else (speaker phone, etc.) works fine.
I've seen a number of similar cases in other forums, so I'm thinking that this is a weak point. I'll attempt disassembly and see if the speaker contacts got moved or something simple. Fortunately, replacement receivers/earpiece/speakers are available over the net.
Meanwhile, I'd love to learn of others' experience with this. The tech manual makes it look like you have to just about completely disassemble the phone to get at the earpiece, even though you can easily access 3 screws on the back of the lcd. Is there a shorter route to the receiver than a complete disassembly?
[update] I found some good info (including a technical manual) by Googling "g1 phone disassembly". And searching for "g1 speaker" on eBay gave some decent looking results.
[update 2] I disassembled my phone, took out the receiver, cleaned its contacts, replaced it, and and reassembled everything. That was a pretty serious chore, and it demonstrated that a nearly complete disassembly is required to access the receiver (yes, including all the stuff at the opposite end of the phone). I don't know how to test the receiver without being in cell range, which my house is not. But at least nearly everything else still works, except the camera--I need to tear back into the phone and make sure I fully seated the FPC. I think finding a replacement receiver will be a challenge--most of what turned up on eBay is actually the main speaker on the back of the phone, and I have yet to find a vendor that sells receivers.
Sadly, you will almost have to tear down the whole unit to get to it. It's not extremly diffucult, but you will need to be steady and gentle. Good luck.
Success!
I haven't seen many report back after tearing apart their phones to address issues with a bad receiver, so here goes. My simple-minded approach of opening it up, cleaning the receiver contacts with a pencil eraser, and ensuring good alignment before reassembling WORKED. I did not have to buy a new receiver.
Now if I can just get my camera to work again (I think I didn't get the cable well seated).
[update]: camera works! Seating that FPC took some nimble fingers--I got it on the 3rd attempt. I hope this proves useful to others who, like me, do not have the warranty option for various reasons.
I dropped my phone once, by accident, same thing happened. The speaker you use to put your ear up to when making a phone call doesn't work, but the speaker phone speaker works as does a bluetooth headset. Called HTC lied said that it just stopped working out of no where, they said its covered under warranty. Luckily the phone is under warranty until March and will be replaced.
I ran into the same problem. I was having intermittent problems with the earpiece. Yesterday I was able to take out the battery and put it in and it started working again. Today that didn't help either. I saw this thread and I thought that I'd try blowing really hard on the earpiece to see if that helps. It seems to be working again! I hope it continues to work.

Can you post details on how to do this?
My camera stopped working too.
I personally found it easier when disassembling the phone to carefully lift the entire camera and IMEI sticker as a whole unit and remove it as part of the motherboard. That way you dont need to mess with that hard to reach connector. So from where you are at, lift the board back out, reattach the camera assembly, and reassemble as a unit. I think you will find it is MUCH easier
Seat the camera FPC fully

I had to lift the motherboard up and away from the hook that held it down in order for the FPC clip to open fully. Then I inserted the FPC *fully* before closing the FPC clip (my failures resulted from not being able to fully seat the FPC because the FPC clip could not fully open as long as the motherboard was in place). Then the trick was to get the motherboard back under its hook without accidentally pulling the FPC back out again. What I did was to press it gently straight down, using my fingernail to ease it past the hook.
Good luck!

Yeah looks like all there is on Ebay for speakers is the back one, the one for the receiver earpiece looks like it has two wire connections at each end while the one for the back speaker has them right next to eachother.
So if anybody had this problem, it is very odd and might have to do with the spring connection maybe.
Still I had this problem before and it fixed itself randomly, but this problem came out of nowhere because 12 hours earlier I had dropped my phone on its back and it continued to work fine. Than on my way driving randomly it would not work and I barely set it down in my car.
Once again hopefully somebody has found a part for this because ebay only has back speaker parts.
Best bet is to blow on it and massage it or tap it until it works, damn this sucks because it is basically the very last step to get to after dissambling your phone. So much work to get to such a common problem for many people.
I almost wanted to try to shortcut it and undo the two screws on the screen section to move it around to make connection. Now I am the deusche bag with the bluetooth in his ear all the time.

That was what I tried at first. It didn't gain me access to the speaker.
Taking the phone apart is a pain. You really need nimble fingers and faith that you're not breaking the phone when you're levering apart the *very* tightly held together plastic parts. HTC did not make this thing with servicing it in mind. Just be sure to have the right tools (including light and a good magnifying glass if you're over 40) and patience.
Removing the 3 screws that are accessible without disassembling the entire phone will get you in there if you are VERY careful. Unfortunately the one I tried this on did not work differently with a known-good speaker in it. You can delicately dig out the old speaker with a knife (Xacto) and drop the new one in. Takes patients, but not nearly as hard as disassembling the entire phone (been there, done that x10)
I have at least one spare speaker. Maybe more, gotta check my stockpile!
Hey,
My phone got dropped in a rum & coke on Saturday, so i soaked it in 90% rubbing alcohol and let it dry in a rice bath. after 4 days in the rice, it looked dry, so i turned it on. IT WORKS! The screen looks a little trippy (the pattern is even changing throughout the day) but the touch and accelerometer work great. The only real problem is the speakers sound like crap. the receiver is so quiet that it sound like they're wispering, and the back speaker is all crackely.
I found a replacement receiver speaker, but as i haven't taken it apart yet, i was hoping one of you could tell me if this looks correct.
http://www.tvc-mall.com/details/Replacement-Speaker-Earpiece-Receiver-for-HTC-G1-HTCO-G1/photos.htm
If so, i guess i'll order both speakers and attempt to replace them.
That looks about right. Bear in mind, of course, that those pictures are greatly magnified. If you haven't taken apart a G1 yet, you're in for a bit of nerve-wracking prying. Just go slowly and be patient. Getting all the way to the receiver speaker means taking the phone most of the way apart.
Thanks!
I have taken apart a phone before, the Dash (excalibur). I had to replace the screen, it involved removing almost every component.
I think i'll go ahead and order it, and cross my fingers. right now the phone isn't much more then a tiny computer, since i can't hear anyone and i don't have a Bluetooth.
Passed out with a protein shake in one hand, brand new Oneplus 2 in the other. Woke up with the OP2 and my pants filled with a thick vanilla protein pool.
I'm special.
I wipe the phone down- not really knowing how bad I had damaged it, just looked like the screen had some of the shake on it at first glance.
[FYI: the phone was powered on it while it soaked in the protein pool for 5 hours- and stayed on. ]
I flick the notification switch and yep, still running. Immediately powered it off (was also VERY hot). I almost considered it a wash and decided to wait for another invite and keep it for parts, but I want to try to repair it.
Knowing my warranty doesn't mean jack at this point- I immediately removed the bamboo back cover, it looked as though looks like someone spilled ice cream all over the backplate and body okate, this thing definitely got a bath.
Voided the white sticker screw along with the 18 others. Removed the ‘un-removable battery’. Then let it dry (big ol’ bowl of rice). I'm not sure made it worse or better as the protein shake was very dense- the internals had hardened delicious vanilla plaque caked all over upon inspection of removing the back plate.
Visually inspecting the shame, the headphone jack had allowed the shake to trip directly into the mainboard, now half way crusted over. Areas of the part of the PCB I could see looked a little bit wet- I dabbed them with an iso pad, then dabbed with lens cloth and decided to let it sit in a rice-bowl again for another day or two..
Day 5 of drying... at this point, I decided ‘screw it- let's see what works. Put the battery back in and powered it on. LTE-working, LCD/touch/buttons, working.. No Camera/WIFI/Bluetooth/Speakers/GPS do not work at all. No MAC addresses for WIFI NIC or BT NIC.
Oddly, text/system notifications created output but it didn't seem to come from the speakers on the bottom. No music players could output anything through the main stereo speakers. Calls (earpiece and mic) worked fine.
I sigh, and stare ate the mess of a brand new OP2. It half-ass works. I almost considered it a wash and decided to wait for another invite and keep it for parts, but I want to try to repair it.
I took all of the internals apart minus the LCD/Digi.
Meticulously cleaned for around 2 hours using iso alcohol for the frame edges, headphone jack, and various other parts- also used a PCB cleaner that is safe for use on various plastic polymers/butyl rubber/whatever.
Got the main PCB and bottom PCB nice and shiney, however the items covered by the poriforated EMI shield I cant get into to clean without either a dremel (yikes) or somehow bending/cutting the top off. Any tips here? I believe the WIFI, BT, and audio amp are stored under here.
At this point, If you looked at the internals you wouldn't notice anything had been spilled into it (other than the water-tamper stickers being red)
I take a blowdryer to the PCBs on low and the interior to quickly evaporate the iso and PCB cleaner for about 15 minutes.
I waited about 3 hours before putting the battery back in.
Now I have working headphone jack, speakers, both cameras, and GPS (and LTE/GSM has always worked so that's fine too). Now the only problems are Bluetooth and WIFI.. again no mac addresses and they do not allow me to toggle them on.
Full system wipe to stock, and I mean ALL the way stock. Wiped the heck out of everything except the boot loader and even flashed the stock boot loader back on. Still cannot enable WIFI/BT.
Does anyone have any suggestions? Word around here is that you cannot buy the logic board, and the only other options is to buy another or find someone who cracked their screen and use their PCB.
Wow. Just wow.
I'd say, just try another round of cleaning and drying.
You might be lucky 3rd time.
So I find myself with a bricked R4P, fastboot only, no EDL and locked bootloader. Tried every piece of deep flash cable advice I can find, to no avail.
Opening the phone up for the testpoints it is then, but I have no idea how to get in to detach the back cover from the rest of the phone. I have phone maintenance tools like nylon spudgers, but the gap between the phone and the cover is so tiny they won't go in, no matter the angle or amount of force i use (mostly trying around the USB port). I've managed to (unintentionally!) unstick the screen from the rest of the phone without even trying, but can't get anywhere with the back cover
Anyone here familiar with opening up an R4P and can offer some advice on how to go about it?
Edit: Forgot to mention, the bottom screws and sim tray have been removed.
Look HERE and good luck.
I just did the same thing today. I also did the same thing as you, I was somewhat thinking it was the screen but there was only one way to find out. I had to use quite a bit of force and go over it many times with plastic tools. I started to pry it up slightly and put guitar picks in, that worked alright. I got a metal tool and pryed it up a bit, then used it to work around the outside.
I'd hear sounds when I could get the tools in, not sure if it was the plastic bit bending inwards below the metal cover or if it was breaking the seal. I was going slowly to be careful. It might be noticeable when I put it back together, I'm not sure.
I saw a video where the one guy used his fingernail to pry it apart in like 30 seconds. I feel he has already taken it apart.
I tried hitting the test points and it wasn't coming up under the COM ports for me. Nothing I have done has had it show under COM ports (maybe EDL would have worked, it didn't on a few computers and VMs that I used). I will try again tomorrow.
Edit: Other videos made it seem super simple also. Admittedly I don't have tons of experience taking unibody phones apart but it seemed harder than the videos implied. Others may have some technique tips.
I'm not sure if it's mentioned anywhere but I think the three screws to the cage are Phillips 00, it what worked for me at least.

So I find myself with a bricked R4P, fastboot only, no EDL and locked bootloader. Tried every piece of deep flash cable advice I can find, to no avail.
Opening the phone up for the testpoints it is then, but I have no idea how to get in to detach the back cover from the rest of the phone. I have phone maintenance tools like nylon spudgers, but the gap between the phone and the cover is so tiny they won't go in, no matter the angle or amount of force i use (mostly trying around the USB port). I've managed to (unintentionally!) unstick the screen from the rest of the phone without even trying, but can't get anywhere with the back cover
Anyone here familiar with opening up an R4P and can offer some advice on how to go about it?
Edit: Forgot to mention, the bottom screws and sim tray have been removed.

If you haven't open yet then Use the Chinese Recovery Method as its work fine For me.
Thanks so much guys.
@Pyro00 - I've just gotten 9008, so here's exactly what happened, hopefully it'll help you out:
Have the battery well charged
Boot into fastboot mode (Power+VolDown)
Have the phone connected to the PC
Type "fastboot reboot" into a command window where fastboot is available (e.g. "c:\program files (x86)\minimal adb and fastboot", if you have that installed), but don't submit yet
Short (and hold) the two testpoints (to the left of the left-side battery connector, just above the battery)
Submit the fastboot command - phone will "power on" vibrate briefly, then do nothing - you'll be familiar with it I don't think it matters how long you wait as this point, as long as you give it a few seconds
Release the testpoints - the phone will power on vibrate again
Quickly (I'm not sure of the timing) short the testpoints again. The PC should immediately recognise the phone as 9008.
