hi,
my htc one m8 doesn't see my sim card anymore. also a new one.
when removing the sim card the it says "sim card removed"
i've do a full software reset. and also reinstalled the firmware.
when i do a google, on repair shops i see that it's fixed by mainbord soldering.
Any one any idea what they are soldering to fix this?
thanks
Do you still have warranty on the device? If so, rather take it back to have it fixed/exchanged instead of attempting a DIY that'll leave you possibly messing up your device. If you don't know what to solder then it's probably not a good idea to attempt such things.
Maybe try the old HTC One trick of the tape at the back of the tray that holds the card, see if maybe the problem is that the tray doesn't allow the card to fully make contact. The tape should be enough to force the card down a bit more and press it into the circuitry. If this doesn't work then you might have another problem, either radio firmware isn't right or it's a hardware issue in which case it'll be better to take it in for warranty and/or repairs(from a professional or carrier service center).

i cant install install any radio rom, my phone says no gsm. i bought the phone on line, and i dont no what rom was it before, but it has no gsm. then i flashed many radio roms with universal ruu-cid bypassing, but cant install..does not move, stuck at 0% then updat error, i have a g3. and i already searched thru the forum. but those didnt help at all...some solutions i found:
- flash with sd storage, he just posted a pic and didnt explain anything and never reply
- check ur id or something and make sure u have the same id? flash it back to original rom- which i didnt no what rom was installed in this phone before...then he didnt explain..
so, im wondering can any1 plz explain step by step how to flash any raido rom, or i have the feeling that its broken anyways, but wanna fix it if i could. thx in advance to all yall nice ppll
Try installing a WM5 ROM and then reflashing the radio. Also check the version of the bootloader, as that may be causing problems as well. I just updated mine to 1.01. Have been looking for 1.2, but the file available ay the wiki section doesn't seem to work. By the way, do you just not get any network signal, or do you get some sort of messages to that effect???
Cheers!
what does the new bootloader do? should i update the bootloader firs and then try to flash the radio rom? or just flash it back to wm6 then update the bootloader? 1 more thing, will any wm5 work?
I've got the same problem too.. I think it's a defect on the motherboard. I am loosing the SIM card at random intervals, I can't get it to happen - it just happens...
I am buying a new M/B I think something went wrong with the GSM part of the UNI.
Ariel
I have the same problem with "invalid sim card" ... As I have friend who's GSM repair guy, I got my card reader replaced, and also tried flashing new radio ROM - still loosing it - occasionally it's "no service", and at other times "invalid SIM"
I'll see if my friend will be able to find some bad soldiering on the MB and maybe fix it (optimistic outlook
If anyone solves this notify me
I think it maybe some microswitch on the motherboard, I switched sims - it's something else wrong with the radio part of the jasjar
--summoner
I had similar problem and it was connected with the metal pin where the SIM card is inserted, since it was not pushed enough to get contact with the module. Try this maybe can help
I tried, bent them some and sprayed contact cleaner everywhere...
nothing
COnsidewring the increasing issues of NO GSM, and as such now we have memory upgradation being done, here is the way to tackle the issue.Pls note and understand carefully what u are doing and then proceed.It involves hrdware skills.
-Open the Universal as per the guide and locate the Qualcomm Chip and Radio section, which is near the antenna.
- Apply the flux on the Qualcomm Chip and hot blow it mildly and carefully.This will eliminate any kind of dry solder and enhance the contacts of the chip.
-Reassemble and Immedialtely flash the Radio ROM only.If u can flash, then when reboot, it will show Radio None, insttead of NO GSM, as in case of Blue Angel.Soft reset again and u are back to normal Radio Version.
I hope this helps.I have been able to recover several Unis with this technique.
So you are saying the radio chip needs to be resoldered because some connection is loose?
What do you think is the reason?
--Summoner
Sorted!
I did as hdubli suggested and it worked! my uni has worked for 18 hours straight now whereas before would lose the sim every 10 minutes or so. Quite scary - although I have a rework station, I have never used it on anything so valuable before!
Thanks for the advice,
John
Cool,
What do you mean rework station? How can I do it myself? can I order this FLUX online?
Can you supply photos or more detailed instructions?
--summoner
Summoner,
a rework station is a hot-air blower used for soldering the very small components found in mobiles and micro-electronics. It is possible to melt all the solder under all the pins of a chip at the same time and if you use a little flux to prevent it ixidising when it melts, you can get all of the joints to be perfectly made. A rework station will cost at least $100US and you do need some practice before you risk your uni, but if you know a local phone-repair shop, they will either have a rework station or know a "man who can". Hdubli suggested reworking the Qualcomm chip in the radio section - the picture in the wiki shows at least 3 Qualcomm chips, so I did them all!
If you're happy with the concept and fancy having a go yourself then google for a local distributor of "aoyue" - they are a Chinese manufacturer of rework kit, and any electronics dealer that sells soldering kit will sell you a "residue-free flux pen". I got mine from Maplin.co.uk here in UK for less than $10us.
hope that helps,
JT
Thanks for your reply... I'll see if to get a rework station, it looks interesting - I know how to solder and stuff. but never used a rework station.
Does anyone have online instructions/tips for using?
--Summoner
www.sparkfun.com has some great tutorials on hot-air soldering and reworking of surface mount components. If you do get a rework station, I recommend a lot of practice on some dead gadgets before you risk your uni!
Best of luck with it,
John
Any luck with this rework method?
I tried to rework but no luck.
no gsm with htc phones/hermes
Hey, just a shot. ATT won't help worth crap and their customer service blows. I found out that if you do a hard boot to flash rom you need to remove the sims card. I am not sure if that is the procurring cause of the no gsm issue, but I don't have a data package and they program that sim to block the gsm! Well, blocking the gsm during programming also blocks your device from setting the parameters correctly for acquiring the imei, radio, and protocol version. DUH ATT! They admitted that they dont service the devices to me on the phone. That's my 2 cents. If it works for others let everyone else know. Now, can someone explain to me how to upgrade to 6.5 and where to start for programing this thing to do great things! Thanks, Ryan

Welcome to the forum
You are in the wrong section
Universal does not means all HTC devices, it refers to a specific model
Try to look into the proper section of your device
Good luck,
Hey everyone. At one point I had removed my sim card to play around w/ Android on my device. Not wanting to lose it, I put it back in my phone, but now it refuses to see it. Its not the end of the world, as I am on VZW and don't need it for international travel, but it would be nice to get it working. Is there some trick I am missing? The instructions make it seem like you easily slide it in and out and "it just works" (TM). Ive tried removing it and installing it tens of times already, trying various levels of pressure and jiggling hoping to make the contacts line up... No go.
Any insight would be greatly appreciated.
Sounds like you may have damnaged the sim card then if its not reading it. It can really only go in and out one way properly. a square peg cant fit in a round hole sort of deal.
So my bet would be its screwed up somehow. Just go to verizon and tell him its not working and you can maybe get them to give you one or they'll make you buy one. They can probably test it out in one of their phones and see if its working actually.
Hi there,
Powered off my Desire Z and removed my microSD card earlier and of course the battery too.
Put the battery back in and it no longer wants to turn on.
Tried charging via usb cable and the AC adapter, but the charging notification LED remains off.
I had the engineering hboot, but I can't even get to that...
Hoping a button or battery issue, but I have no way to tell.
Is there anything I can do to try to revive the phone?
Thank you!
Is your SIM and SD card seated correctly?what about the battery connectors are they clean?Seems strange that it suddenly stopped working

I assume it can still power up without a SIM card or SD, right? Currently have neither in the phone. I removed them both when it wouldn't turn on the first time.
No corrosion, gunk or fluff on the battery or the connectors.
Very strange indeed. In warranty, thankfully but I'm still taken aback that it just died. I wasn't doing anything dangerous like flashing the hboot and yanked out the battery in the middle of the process...
Would of thought so,just to rule out stick the cards back in and see what happens??if not, at least warranty's got you covered,wonder what happened.......

No luck. Ready to blame voodoo curse at this point.
if you have managed to brick your phone, and for some reason the warranty claim is rejected for some technicality, all is not lost!
that MobileTechVideos guy on here can un-brick most any G2 for $40
go to youtube, he is easy to find on there
the famous un-brick dude here at XDA

Thanks for the link and info. Hopefully it doesn't come to that, though.
Asked HTC nicely to ship me a battery to see if that was at fault. If that doesn't help, I'll just have to return the phone to them.
After installing CM 12.1, I started getting the "SIM Card Removed" error pretty frequently.. it's very annoying. I've been doing some research, but I can't figure out if it is software or hardware. Please advise.
By the way, I have had this problem on CM 12.1, CM 10.2, and Resurrection (which is based on CM 12.1). I will be trying the Google Play Edition later today, and I will go back to stock 4.4.2 if I get the error on GPE. I'll update on my results.
UPDATE 10/5/2015: I found a solution! If you take a small piece of plastic (I used a piece a little smaller than my SIM card) and tape/glue it to the inside of the frame, directly on top of the SIM holder, it applies enough pressure to keep the connection. No more error! It is a hardware, not software issue.

It's a known hardware issue; contact your carrier for a warranty replacement.

Thanks for letting me know! I ordered the replacement part on ebay for $3. I'll update with my results.
In many cases its not the fault of the sim card holder, but a poor connection at the ribbon cable connection to the motherboard. Several folks said replacing the holder/cable didn't fix it because the problem is due to the motherboard part of the connection. Several reports suggest pressure on the connection where the ribbon meets the motherboard, by bits of foam or whatever, can remediate the issue.

Thanks for the info! I will repair the connection itself if the new holder doesn't fix the problem.
I get the error message off and on, but for some reason when I loaded CM 12.1, it triggered the error message continually. Had to go back to stock. I don't know why, seeing as it is a hardware issue, but my phone sure didn't like CM!

There is a long thread with many solutions offered here :
http://forums.androidcentral.com/sa...4-major-problem-sim-card-not-detected-11.html
Just thought I would post my final solution - I have been dealing with this error for a LONG time! I dropped my phone last week and it wouldn't recognize my sim card at all. Lots of searching, watching lots of YouTube and this is what finally worked. I had to remove the back cover, then remove the back of the phone. I used 2-way tape to tape a small piece of an old customer rewards card (others have used a piece of a guitar pick, but I didn't have one) across from the connector for the sim card/sd card reader on the inside of the back of the phone. Finally, no more sim card error.
I tried to put foam inside the back cover, etc., but it wasn't until I actually took the back off the phone and applied the fix that the error finally went away.
Hope this helps someone!

I found a solution as well, thanks to these two posts. What ended up working for me was to cut a small piece of a plastic card and glue it to the frame directly above the SIM holder (on the inside of the frame). I have been going for over a week now with no error!
Awesome thanks having same issue for months now.
Hi,
recently my zenfone 2 got very hot in my car, I used it as GPS and charged it during the trip.
And BOUM, I was writing a message and the Sim card suddenly stop working .
So I tried the Slot 2 twenty minutes later, it worked for 1-2 minutes.
I thought it was a ROM issue, so I switched to a complete new ROM (the lineage one) but that not solve the issue. I just see that the vibration motor doesn't work either .
Finally, I think it is a material issue... I already bought the Sim slot card piece replacement for changing it myself, but how can I know if this will be enought ? Maybe is this a little part of the motherboard which is dead ? I don't want to desesperaly try to repair my phone and loose the guarantee (I expect that I already loose the guarantee with the unlock bootloader/root).
If anyone had a similar experience, please share it with me :highfive:
Thanks

well here may be two scenario. A. too much heat damaged the components. B. heat caused the components to desolder.
take little soldering paste and apply heat to components especially ICs

Ok thanks, I'll try it before open it and install the new card slot... What do you mean by ICs ? And Do I have to unplug the sim card slot to apply the paste ?

i didn't get you point. you do not need to apply paste to sim card connector. i meant to apply paste on motherboard components. like processor, power ic etc. better do not heat the emmc though
