Hi there
Can anyone help me please....?
I have a HTC Evo 4G LTE phone that i got from my friend as faulty.
The screen was broken etc..
I have replaced the screen and the phone starts up and works fine. Wifi is good and the sound etc is good too.
The only issue that i have with the phone is that i cannot get any network signal regardless to what ever network i use the sim card from.
I know that the phone is unlocked.,
Does anyone have any pictures of the back of the phone with the cover removed so i can see if there are any wires etc missing from the phone, or does anyone have a repair guide / manual that they can guide me too??
Thanks for you help .....
the evo lte is a cdma phone, so no sim card to be changed or swapped. and if you google something like "evo lte teardonw", evolte repair guide or evo lte disassembly you should find what you need. good luck, I didn't have a network signal, but I think my phone didnt like the rom I was running.

Issue resolved
Hi there
I have sorted the issue out and thought i would share my route to the remedy of no signal.
On the mother board you have the antenna cable that connects at two points.
The problem with my antenna cable was that it was damaged and could not catch a good signal.
The remedy was very easy and cost me £1.00..... i just got a new cable and installed it.
Simple 5 min job - phone works great !
Thanks for all your advice guys....

Hi folks, can anyone please help me with this problem?
My brother in law has asked me to look at his S740. He has tried several o2 SIM cards (UK) in this phone but always gets told there is no signal.
Not only that, but there is a symbol where the strength meter should be that isn't documented in the user guide.
He has also tried my o2 (3G) sim and a Vodafone sim, both UK.
Any advice gratefully recieved. We have tried several hard resets also.
Thanks
This means it's looking for signal. My guess: Still SIM-locked?

Not sure if it's SIM locked as there is a menu to select which carrier to use.
It reads the SIM correctly and sets it all up for o2, but just doesnt get any signal.
Does anyone know where the GSM antenna is on these? Maybe its a bad connection.
UPDATE:
I've had a mail back from HTC that recommends I send it in for repair, lol.
Now do I take it they are robbing buggers or do I take it that the icon is an indicator of a hardware fault??
Hmmmm, dilemma. lol
Are there any more suggestions on what it may be?
Has anyone successfully taken one of these apart?
it may be because of a hardware error...try to connect to a wifi network...if it impossible to find a wifi network then it is due to a harware problem.Most likely because the FR coaxial cable is out of its possision...download the service manual and see how to fix it.

Hi sasiskas, it conects fine to my wireless network at home. I take it from your response that the cable serves a double purpose.
I downloaded the service manual so I could take a look, but only got as far as removing the 4 screws at the back. lol, I couldn't figure out how to get it off, lol
I'm still stuck at the assumption that it is indeed SIM locked, and so will try to find a suitable card to try out.

Try contacting with your phone's provider (shop,e-bay seller whoever it is) and ask him details about the sim.Good luck.

Thanks. I have tried the same but just keep getting a vender ID, (lol spelling), error.
I would appreciate any input whether you have success or not, it just may spark an idea off.
I cant get in touch with any sales or provider as it was gifted to my bro in law. He's not that bothered about it but would like to have it working if he can.
Thanks folks.
Hey! I think I know the solution to your problem...I had exactly the same problem when I hardReseted my phone.
Go to "Start-settings-Phone-Band Select"
and then select
1.Network type : Auto
2.Band Type : "Euro" if you live in Europe, "US" if you live in USA , or "Japan" if you live in Japan.
Good luck...Let us know if it worked!

Yes that is a good suggestion because the phone will display that icon if it can't find a *usable* network, be it that the SIM doesn't allow it or if the bands don't match the selection on the phone or the bands are not usable by the phone hardware etc.
I would suggest downloading & running HTC Field Test (fieldtest.exe) with & without a SIM installed, with each network & band setting & see if it shows any towers or signal. (Normally you want Auto for both but you may not have that option or you might prefer to set to a KNOWN working band to conserve battery & minimize searching) If should show something even without SIM or with SIM lock because it's supposed to support emergency calls either way. If it shows signals with SIM but you still have same no service icon then it's likely SIM locked (although the phone should alert you to that fact) so odds are the phone hardware, rom or settings do not support whatever signals are available to you. (Btw if field test shows N/A for all the values you need to app unlock your phone)
Hope that helps.
Bill
can you share a link with HTC Field Test?Thnx
Search is your friend.

Hey all I'm having a very similar problem.
Had my HTC for some months now but in the past few days I've found that my network signal is becoming very unpredictable.
I'm also on O2 and I used to have a pretty contstant H (I presume HSDPA) connection.
Howeever im finding now the phone with go from H to 3G to GPRS to E to no signal in the course of 5 mines and round and round again!
Its very annoying as it means I cant make / received calls or texts fluently and even cut me off on a phone call too.
However usually on phone calls it will keep me connected ok till I hang up and then go to no signal.
I've checked the wireless and it is picking up networks..
Any other suggestions? I will try the field test tomorrow...
PS I know its not the network as my work blackberry is O2 and is not having this issue..
Cheers in advance!
Well, just to close my input on this thread.
I tried various ROM's available from this site and none worked.
I did try the band selection settings but still a no go.
I did have limited success but overall, nothing. The phone has now gone back to the person who asked me to look into it and to my knowledge he is going to sell it to one of these phone reclaim companies.
I did check and one place, I think through the post office, is offering £80 ish so not bad I suppose.
Anyway, thank you to all who have made suggestions and wotnot. Personally I'm still happy with an old Nokia 6300 and my Wizard (Mini-S)
Thanks folks.
Hello Problem solvers
I am going to buy an HTC Amaze , but there seems to be a little problem with the network of the phone , below i have stated down the exact lines what the seller has told me. Please suggest should i buy this or not.
The seller says :
"I bought it from someone and everything was unused. I put my sim card in and it worked for a few hours then it was unable to read my sim card. My sim still works on my other smartphone, but I do not have the time to find out what is wrong with the phone. I've tried other sim cards from other phones and also did NOT work. Seems like it won't connect to the network no matter what. Maybe the phone is locked or is not able to be used for whatever reason. Everything on the phone works perfectly as new. WIFI, apps, camera camcorder, games, etc. Everything.. Just doesn't seem like it will get any signal from the service provider. Possibly someone will know what to do and can fix or modify it. Can use it like it is or take it for parts, I don't know. Comes with all original equipment: USB cable/charger, manuals, and will have 8GB micro SD card. AGAIN, THE PHONE IS NOT CONNECTING TO THE NETWORK (SERVICE PROVIDER) AT ALL."

He later adds on to his saying :
UPDATE: Actually, the phone recognizes when a sim card is in, but will not connect to the network to make a call or connect for data. I am almost sure nothing is wrong with the phone and possibly could be a problem with the network or service provider.

Has anyone experienced this before? Please let me know what should i do, The price in which he is giving it to me is very good. If there are any solutions for this problem , please mention.
Thank you forum!
Regards,
Hmmm....the phone is like a month old. It is still under warranty. Why isn't the seller getting it fixed rather than take a loss? I'd be very suspicious. It could have been reported stolen and locked down. My spidey sense is tingling.
My replacement did this, I went into network settings and chose network, search automatically and wala problem solved. But still don't hand over the green until your sure.

Could the IMEI be blacklisted?
You have to call Tmo and have them register your sim. I had same prob when I first got amaze.
Sent from my HTC_Amaze_4G using XDA App
it might also be the sim card ... i know when i bought the amaze from the tmo store they said it will not take the sim from my old phone and that it only works with the sim card that came with the phone...
Whats up folks.
I have a HTC Desire X With Stock firmware, Android Version 4.1.1. Problem is that 3G is not working on it. I have checked the settings and everything is fine there. I have troubleshoot a little bit, by exchanging both the sim card and the phone, and there is deffinetly something wrong With either hardware or software of that particular mobile phone. The problem is that when i turn On/Off the mobile data button on the phone, it simply does not do anything at all, apart from turning the little text right beneath the Mobile data from Off to disconnected, and all this occurs in a blink of a second. I never see any bar in the status bar whatsoever, seems like it is totally dead. What should i do? should i reinstall the firmware on it, in that case how? And please dont talk about custom firmware as this is mobile phone is owned by a Company and not me.

Why not contact your service provider and tell them that you cannot connect to 3G it might be some problem with your service provider

Check if you have the right APN's for your service provider. Also, check if the Desire X's bands match your service provider's bands.
I had a similar problem because I used the sim card older than 10 years, when I changed and put a new one everything was ok

Sorry for a delayed reply but i have already checked the things you guys are mentioning without luck. I have used the same sim in another cell phone and it worked just fine. I also used the other cell phone and made sure desire x had the same settings as the other one but didnt help at all.
I am experincing another issue with another Htc cell phone aswell, its Htc one S, it simply is unable to detect my home wifi, it scans and finds all other wifi networks but for some reason not mine at home. I got like 10 other devices connected to tht particular wifi so wifi and router is just fine. But htc one s is simply not detecting it, what to do?

hmm guess you network antenna has some issues have it checked with a HTC service centre as a friends of mine had the same wih his one x+ and he replaced it so it might be the same case for you its not your sim provider thats causing the problems
HTC one s has a lot of connectivity issues and i have seen it often resulting replacing the motherboard in worst cases however i also get this error on my desire x quite a lot of times you can do it in two ways...
method 1- delete your wifi set up in your phone of your router and hit reboot and then try it should be able to detect it
method 2-if you are a person like me who has the router constantly on due to your wifi needs disconnect and reconnect your router after a few mins it again should be identified with you phone dont know why HTC phones does this but its a common thing...

Thanks for replying, but dude as for the HTC One S, i do not have any profile of my own router stored on the phone, which i can delete, because i never get the chance to connect to it, as it is not showing as an option to connect to, simply because htc one s is unable to detect it at all. I will give it a try to reboot my router and see if that helps. as for the htc desire X, i guess i have to send that telephone back for service.
Hi
I did reset my router, and it finally started to appear on my cell phone, thats nice. But i am having some other issues. Now i am connected to the wifi but it wont work on internett or any other thing working with internett. With other words, i do have a connection, but still nohing is working. And there is nothing wrong with my WIFI.
Another questio, how do i reinstall the stock firmware on HTC desire X?
So I have a Note 2 and a HTC one, for about three weeks I used my HTC one and then i switched back to my note 2. Yesterday I wanted to use my HTC one but every time I insert the sim card I get a no service message. what can I do to fix this?
I did not root the phone BTW.
Have you found a resolution? I just ran into the same problem. Phone was working great, then one Sunday afternoon it just stopped getting a signal. It's not the SIM as it works fine in my old SGSII (had to make SIM adapter). I am rooted and unlocked and running non stock recovery but still on stock kernel/radio. Haven't contacted HTC yet for obvious reasons.
I've had this happen a lot with my phone on tmobile. I live in a concrete basement apartment where there's no reception and if the phone goes more than 15 hours without any signal I almost always(80%ish) have to call tmobile and have them deactivate/reactivate the sim from their end.
A fix you can try that they swear "usually works" is go to settings/mobile data/network operators/search automatically
If that doesn't work then try settings/mobile data/access point names/menu/reset to default
Apparently these settings can be reset pretty easily when the phone doesn't connect to a network for a bit, but all this might just be a tmobile thing
I have a bit different problem - I bought HTC One from T-mobile and unlocked it. I tooked it with me to Europe and device does work with american sim (ATT and TMO) but it wont recognize any of my national carriers. Insterting simcards(perfectly working) does not give me reception or anything. Sim cards are the same thing in EU and US I think - also those are GSM phones. I have friends having same problems with their S4 from AT&T in Europe. Does anybody know something to help make this device work?
OP - this happened to my Wife's phone for no apparent reason one day. I simply removed & reinserted the SIM and rebooted a couple of times, hasn't had a problem since.

I changed my SIM for a new one. Seems like a new SIM cards are a bit different from the old ones because after I did that I had no problems

Same problem here. I am on paranoid android though so maybe that has something to do with it. When I go into the settings to connect to the t mobile network, it says "your sim card is not authorized" or something like that. Maybe it's cuz I haven't paid my bill for 2 months? Lol but I don't think that's reason for them to block my sim :/

I had the same problem and I had to restart my phone sometimes several times a day, sometimes I had to remove the sim card enclosure and reinsert it in order for my phone to get a signal. So I contacted HTC and they told me that I probably had a defective sim card enclosure so they sent me a new one. After I installed the new sim card enclosure with the same sim card I had before the problem went away. I've been without any problems for the past four months or so since I got the replacement sim enclosure
type *#*#4636#*#* -> phone information -> make sure GSM/WCDMA/LTE Auto selected and Turn off radio
If you see turn on radio click that to turn on the radio. Is some cases the radio gets turned off and a reboot doesnt fix. This is the only way I know to recover it.
I've this same issue!
Did anybody found a solution?? I already tried everything... but seems like the phone is not blacklisted.. in case it is, something I can do? besides change my IMEI.
Thanks!!

Radio chip
I wonder if anyone can help please. My M7 can't connect to the network. The radio isn't turned off, I checked using the code given by Shane_pcs, so I know it is a hardware problem. I suspect the radio chip has worked loose somehow and isn't making contact like it should. Any tips on how to resolve this please? I have seen a tear down of the M7, but don't know if anyone on here has attempted to secure the radio chip before...not even sure what the chip itself looks like. Any ideas please? Thank you.

Hello! I want to start by telling my english is not the best so i will do my best.
I have an s6 edge 925f that is around 1.5 years old. The battery is really bad so i watched a change battery movie on Youtube, ordered new battery. Got the battery and started to open up my phone.
Everything whent well some things was hard to figure out but nothing was broken and new battery is in. I started the phone and tested functions to confirm everything was ok. So i thought everything was ok until i was going away from home and my wifi was away. Now i noticed i got none signal from gsm.
Checked my sim card and controlled all settings and nothing helped. Opened the phone again and could not find anything wrong. So how can i continue my troubleshooting? Where is the antenna and what could got broken?
Another wierd thing is when i was drivning into another village my LTE signal found network so i thought everything was fine so i drove home. When i got outside LTE area the gsm was totally off again.
Any ideas whats happening with my phone?
Best regards Christian.
Anyone?
I have the same issue. I checked everyhting and all is well connected. Sometimes it will take LTE/4G signal but the phone gets very hot. If I leave it to GSM only I do not have any problem. Temperature is normal etc.
I have same issue with my phone and i think it is GSM unlock or faulty GSM IC because i purchased it second hand from somebody
Somebody told me i can fix this issue for you just by software modifying but i didnt trust him, have you checked your IMEI is real by checking in imei.info
The IMEI is real. The location of the antenna is in the midframe? Maybe a bad connection of some kind.
