[Q] Htc One M8 complete signal loss - One (M7) Q&A, Help & Troubleshooting

Please help! I bought a Tmobile Htc One M8 and I was using it with a Simple Mobile sim. Everything worked fine for a week. Two days ago I was driving and went into a large "dead zone" with zero reception. After I came out signal never came back. I have tried everything from factory reset,new sim card,changing apns,network operator option,etc. I can not get a single signal bar. Can someone help me?

Wrong forum this is for the m7

I had this issue with the Atrix 2 and never found a solution. One customer service rep advised to try a new sim card. They are free to exchange at any corporate owned ATT store.

Thanks for the reply Jeff. A bit of searching convinced me to go with a different phone afterall.

Same issue here but I've watched the bars dissapear, go to the ! EmUse only icon, and then come back. Seems to be sporadic though as the phones been fine for the past few weeks. Figured it was just a bug or an issue with the towers around here.

Lost LTE connectivity after upgrading to JB

I did the JB upgrade 2 days ago and completely lost any LTE connectivity. I set it to LTE/CDMA/EVDO and it just turns into gray signal bars....no LTE at all. Ive done numerous reboots and still nothing.
anyone have a solution?
I'm using the one that includes .../GSM/WCDMA. It works for me with LTE.
just tried, no success.
was reading on the Razr forum that i might need a new SIM card
I'd complain to Verizon even if your warranty expired. I think if an update breaks your device, they should still be responsible.

I went to verizon, they forced me into doing a hard reset, which made it work.

Had the same problem and could only get 3G. Got 4G back by using *#*#4626#*#* and set my radio to LTE/CDMA/EvDo. Then took the SIM card out and put it back in. 4G came back and has been working for the last 48hrs.
I had to do a hard reset as well, but it worked.

Great tip. This just restored my 4G, too. Sure beats doing a hard reset IMO!

HTC ONE Developer Edition Not Connecting to 2G network In India

Hi All,
I am using two Units of HTC One Developer Editions. With one handset the problem is it's connecting to 2G network. 3G works fine. I tried with MTNL sim and it worked and after that my first SIM which was not connecting to 2G also worked and after couple of hours situation came back and now the unit is only working with 3G network. Is there anyone else facing the same problem ??:crying:
Does anyone have any solution for this ??
Regards,
Mahesh
EDIT : After Doing S-OFF , now my handset it connecting to both the networks i.e. 2G and 3G
Thanks Moonlight Team ReOne Team
Mod's Please CLOSE this thread !! Thanks Everyone !!

I'm sorry to hear this, why would you want to use high end phones on 2G network, no offense at all. Just curious

because In india there are some places where we do not have 3G connectivity..
It might just be wonky signal in your area for 2G.
Also if you are using hand cut old sim, just get it changed to proper micro sim from MTNL. I had similar issues with SGS4 and MTNL Mumbai sim until I changed the sim card itself. Hard to explain but it solved my issue. It was very old sim which I cut using sim cutter.
Not facing any issue with 2G signal at all. There are areas in certain areas where I have to go (mainly basement) where there is no 3G and 2G works just fine on EDGE.

So you mean to say there is no problem with the handset, cos it worked with MTNL. ??
But it's not working with MTNL and Airtel.....and yes Airtel SIM is very old i mean it's around 3 years old sim.
Thanks !!
The sim card issues in cases of cut sim cards is well documented to be honest. No matter how well we cut it, sometimes they just dont work right on these newer phones. Over last 1 year I had to get new micro sim for most of my and my family member's numbers as one fine day the cut sim will simply not catch network and then realised the common problem with them all. All of them were cut either using micro sim template by hand or using sim cutters. After getting proper micro sim, the problem went away. This is not specific to One but happens with lot of new phones that require micro sim including Nexus 4, SGS4 and Nexus 7 3G tablets.

What ROM, kernel, mods, etc are you running? Is your APN set up correctly? This could be caused by a number of things.

Did you use the sim from another phone in the note 4 like I did? Or did you get a new sim when you got the new phone? I just talked to AT&T and they said my sim is not on their network, so I should go get s new sim tomorrow myself.

No sir. Used the new tmo Sim that came with the phone. Had the phone since launch, issues started a month ago.
The worst part is I can see all the networks, I just can't register to them!

I bought a note 4 from t mobile a month ago. My girlfriend got her s5 from them the next day. I have a cell tower less than 1 mile away serving up 4glte. Her s5 stays connected to 4glte constant and consistent. Note 4 will not stay connected to 4glte. It connects to G and mostly E. A royal PIA. I have to manually re-connect, sometimes several times to get back on 4glte. What I have done to try to fix: New SIM, Factory reset, Manual re-connect via T-Mobile. Also run with no apps.
Now keep in mind the tmo s5 is working perfectly.
Tmo's solution: Send them 20 dollars and they send me a refurbished phone(to replace my 1 month old flagship that hasn't worked right since day one).
F**k T-Mobile

I have been complaining for a month now. Got a new Sim and no fix. They are sending me a replacement phone for free. Tried to charge me $5 but I complained and they removed it.
Not sure the replacement will do anything but hoping for the best.
Try to ask more. Some agents seem more willing than others to assist.

All of the agents have been pretty good at attempting to remedy the problem up to phone replacement. My problem is they will not guarantee that I will receive a new unit. They have the refurb option which is complete bulls**t on a brand new phone. Especially when TMob separates the phone from the mobile plan. "Buy a new phone phone from us and if it doesn't work properly out of the box we'll send you some other persons problem for a slight fee" should be their slogan. And they are trying to pound on Verizon lol. I hope you get it working on your end. Good luck.
