no reception on my one.. - One (M8) Q&A, Help & Troubleshooting

Hey i've a T-Mobile Branded HTC One M8 one stock Firmware but rooted.
since New Years Eve i got no reception with any sim card.. (Vodafone DE, Eplus DE)
it has a little dent on the back since new years eve.
I opened the device, but all connections were nice and nothing was damaged inside.
What can i do?

If it suddenly stopped with no changes at all to software... And it's dented suddenly.... I'd say it was damaged surely.
Unless something software wise changed?
Or its a Sim card or carrier issue.
But it was obviously banged hard or dropped. I'd be taking it to a service center.
Good luck!

Take out the SIM card and try it on another phone. Since its T-Mobile branded; I would check the imei to make sure that's working from its end http://www.t-mobile.com/verifyIMEI.aspx.

If you've got it opened, check if there are any pins that stand up and connect to the back cover.
There are usually a couple for the antennas, and they might have gotten bent down when the cover was dented.
Pry them up gently and try it again.

No HTC seal on box, have I been given a refurbished or returned unit?

Just received my desire from Devicewire, not on contract but sim free version. I noticed that there was no HTC seal on the bottom of the box, does this mean I have been given a returned phone? I also noticed there is a virgin media widget? Also homepage on the browser is virgin media?
Apart from a tiny bubble in the glass (bottom left, you can hardly notice it) and a back cover that doesn't fit snug, everything else is fine.
My concern is that I will have problems when upgrading the firmware due to some virgin media connection? For example will I only be able to upgrade the firmware with VM firmware?
if you look around on this site you'll see that the general consensus is that due to stock shortages, HTC shipped some phones that were meant to be locked by Virgin, but in fact are still unlocked phones. I don't have one myself, but you shouldn't have any issues with it
that being said, I'd be a bit off-put by that, couldn't stand looking at a branding if I didn't buy it that way in the first place. I mean, the phones are usually knocked down in price due to branding and contract deals..
I'd send it back and demand an unbranded one, but you may have to wait.

oh yeah, the seal...
sounds to me like someone opened your box for one reason it another, I'd find out why...
Sent from my HTC Desire using the XDA mobile application powered by Tapatalk
I got a completely unlocked unbraded one from superetrader.co.uk and it didn't have a seal on, but the seal was inside the box ready to be used. So don't worry about not having a seal
mine was also unbranded, etc... I had a seal on the box AS WELL as inside the box.
maybe just confusion in the HTC packing plant at the moment ...

thanks guys for the info. It looks like they just didnt apply a seal at the factory, maybe they were destined for a carrier who adds some doc into the box and then applies their own seal.
I have one of the phones with Virgin branding, too, also from devicewire. I emailed them about it and they assured me it came direct from HTC themselves.
So I emailed HTC and they said it was a firmware bug, where using a sim on the t-mobile network, as virgin is, produces this branding. they assured me the phone is fully sim free and won't have any trouble being updated. I posted the email in the thread about the April 7th phones. i'll dig it up when I'm next on my pc.
I'm assuming you're on t-mobile?

Arrhhh, very interesting. Thanks for the heads up on that. I have used devicewire many times and never had a problem with them, so I thought it was a bit unusual for them.
Mine came without a seal aswell. The seal was in the box unused though.
yes I'm on T-Mobile

In case you hadn't seen it yet, here's my post from the other thread:
-----------
For anyone that is actually curious, I emailed HTC about the rogue Virgin Media branding on mine:
Hi,
I ordered a SIM free HTC Desire from devicewire.com, and while the phone itself is just fine, I noticed some branding for Virgin Media. There was a shortcut on the homescreen (I assume to the website but I deleted it), the browser's homepage was set to Virgin Media and there is a Virgin Media scene that I can't delete. Devicewire assure me that the phone is a SIM free unit delivered directly from HTC so I was wondering if you had any idea as to why this branding is there?
More importantly, I'd like to confirm that this branding won't affect my ability to update the phone with HTC supplied firmware upgrades.
I look forward to hearing your comments.

And here's their reply:
This is normal. There is a very minor bug in the generic rom in that whenever it sees a SIM from a netork that uses the T-mobile network (T-Mobile, Virgin, Fresh etc) it creates that virgin link and scene.
this will be fixed in the update so it is nothing to worry about. It is definitely a SIM free device you have.
Best regards,
Pete W

So, assuming that's accurate I guess it's mystery solved!

When I bought my Touch HD from the carphone warehouse it was unbranded and didnt have the seal. That was in the box. I was told that is how HTC distribute them. It was/is so that networks can brand them and then apply the seal.
Im not sure if thats right or wrong but it was covered by warranty.

Losing signal on my HOX

This is weird. When I woke up I restarted my HOX and suddenly signal kept dropping. Keeps saying preparing sim card. What could be causing this? I don't want to keep factory resetting. Seems to be a really great phone but now I don't know if I should return it. Please if anyone can help.

Got exactly the same thing, was told by HTC it was faulty. Send it back for a replacement.

mine is still stock, but I only had problems after I updated 2-3 days ago
had really great signal before upgrade... havent tried restoring fabric settings, but am searching for custom rom, and will try that out
Already happened to me three times where suddenly "preparing sim card" appears and I lose signal. Had to hard reset all the time. Unfortunately, htc shops here in the Philippines are crap. They say they have to send it to service center even if the phone is a week old. For what? So they open it up? I don't want to have a week old phone opened and fixed. I want a replacement.
Have the phone for 2 week now, and today i also faced this problem for the first time T_T (running stock 1.28)
Just great, first the yellow spots that didn't went away and now this problem on top of it ?
I hope it was a coincidence and hope i won't get worse.
I had my microSIM replaced and so far, crossing my fingers, signal has been full almost all the time. I just had the original SIM cut before, so I hope that was just the problem.
I've read about sim cards been cut to micro sim been a possible cause.

Similar fault here with factory micro Sim
Sent from my HTC One X using Tapatalk 2
In Slovenia one carrier has this problem. Only SIM cards older than 2 years work so it is a SIM problem. When I asked them about when they will solve this they told me it's HTC's problem and that HTC is working on the problem. Maybe the next update will fix it. SIM cards of other carriers work ok. So if you can, try cards from other carriers. If anyone knows how to fix this I'd be grateful. I don't want to switch my carrier because other two's 3G network is [email protected]

No signal after diassembly

I've disassembled my p930 yesterday to change the broken screen, but I'm not getting any signal after I reassembled it.
I thought maybe factory reset or re-flashing would solve it but that didn't work, and I've tried putting the antenna cable in and out like ten times.
It won't connect AT ALL to my network operator. It doesn't even detect any networks.
WiFi&bluetooth and everything else works.
Any ideas?
Have you tried flashing a rom that flashes all new baseband firmware etc? Like the ICS leak? Maybe all that is reset when antenna is unplugged. Just an idea. Also sure you have already but checking all connections and solder points on the hardware is where I would start.

Any update i'm having the same issue. I changed just the digitizer not the frame. I even went back to stock and still a no go
The sim card perhaps?

I know it sounds odd, but I dropped my nitro a couple months ago on the sidewalk, and quite literally the only thing that broke was the sim card. I couldn't believe it, but sure enough they checked it at the at&t store and I had to replace it.
Dang ...at least i have my atrix 4g.

I had to get a new phone because flashing nor changing the antenna could solve the problem...
Having the same issue, paid a phone repair service to replace my digitizer and now my phone get any signal, so I pretty much paid $130 so they can break my phone
That stinks

you ever figure it out facing same issue do you think its software or is it a hardware problem?

he said "only thing that broke was the sim card." So neither the phone hardware or software, it was the SIM Card.
What about your IMEI? Check it, I'm using SU640 and sometimes I use a new ROM it lost IMEI, so it can be the reason

SIM card not detected - then detected again

My phone is constantly failing to detect the sim card, usually if I restart the phone or leave it for enough hours it will "find" it again.
Short of reflashing it I'm not sure if there's any way to determine if this is a software or hardware issue. The phone itself is a refurbished one (thanks to the phones insurance replacing it a few months ago), however it is now out of warranty. If it was a hardware fault, how much would it probably cost?
Thanks, Shaun.
The first thing I'd try is a different SIM card or a different SIM card insert (bit of plastic that the SIM sits in).
Has this always happened since you've had the phone?
or
Has it happened since you flashed the phone?
As for the price of repair I haven't a clue (i do all repairs myself), but my guess is in excess of £150
You may want to provide more information before other, more experienced people, come to your aid.
It's slowly gotten worse over the last few months (the first couple of times I just thought it was a once off bug or something, which is why it's very difficult for me to give you an exact when it happened).
The fact that its gotten worse in itself is leading me to guess its a hardware fault - I could have knocked or dropped it and not remember or something.
I don't have any other SIMs but I'll give flashing it to a different ROM or stock a shot first.

Does the phone say no sim card (with icon) or do you lose service?

It has done both, the latter's slightly more common though. Probably more often than both it will momentarily drop out, then come up with a "Preparing SIM card..." message.
Still happening after flashing it with a different ROM. Looks like it's probably hardware :/
Might be coxicial cable that connects the pcb with antenea board they do come off from time to time

Hi there,
i have a similar problem with my device:
network disconnects sometimes (for some reasons ok, as example when i sit in the underground or other places without gsm network) - but then the services doesnt comes back - i'm complete offline. next behavior: i'm just talking with full gsm bandwidth, and for really no reason i get disconnected -> no network anymore, no service anymore.
can it be a hardware fault or should i try to flash the modem (when possible) ? I'm on the latest HTC firmware, device isnt rooted or flashed... it is as i got it from the market.
thanks for a hint what i can try
See above could be that, what network you on?

I'm on GSM (in Germany the O2 network)
maybe the network fault can be solved:
just have read in the vodafone forum in uk and found a hint from a user, who was taping the back side of the SIM card with 2 stripes of plastic.
Have tried this and report tomorrow here if it solves the issue
Tested with taped SIM card and i can say: it works like a charme

Galaxy Nexus won't read any SIM

Hi forums,
I recieved my Galaxy Nexus i9250 european GSM/HSPA+ Version today (Just the tether-slave for my N7 and a phone obviously) but now I have the problem that it won't read any SIM i put in it, I've tried 2 Vodafones and 1 T-Mobile (all 3 are working perfectly fine on other Phones) the problem is that it won't know if it has a SIM in it or not, I don't have to enter a password when I boot up or go out of airplane-mode, I can't connect to any networks or change APNs and I can't change the SIM-PIN (no option for that)
What I've tried so far:
I got it with 4.2.2, I've flashed 4.3 several times, did factory-resets, OEM-Lock and unlock, flashed a few different basebands. I also tried to bend the Pins a little bit upwards, they definetly have contact with the SIMs.
I have no idea what else I could do, I have about one year of warranty left over, should I use it or is there a way to fix this issue?
Thanks for your time and help in advance!
Greetings from germany.

Indeed it was, 3 whole pins were missing! I just took the pins from an old phone and soldered them on there, now it works but That's only a temporary solution, I ordered a whole new Sim-tray and will give the phone to a friend with proper gear for this kind of stuff (really annoying to try and do it with a big soldering iron...)
Warranty might be screwed now but I'm not sure if I would have gotten a replacement at all, I guess not but anyway, I waited two weeks for this baby and didn't want to send it away again but I don't recommend doing this at all
Thanks for your help!
Oh and BTW I figured out what might have caused that, I used a micro SIM in a mini-SIM-Adapter, not such a good idea since this makes the card much thicker, I think that killed it. Ordered a new Sim as well.
