[Q] HD3 no signal!!~~ :(

I bought my hd3 in china .it was unlocked, originally sold to hongkong.
after I went back to the U.S. I kept using my chinese sim card, and everything worked fine. when 7720 released ( it was a long time ago) , I swiped my cell phone, and from then on, my hd3 always tells me that 'no network found'. I tried to search network manually, and I see att and tmobile, but cannot register. now the signal icon has an empty set symbol,...and I don't know what's wrong???
p.s. my att sim card works well on my hd3...I've tried different roms, none of them helped.
the problem is solved, I inserted my chinese sim card into an android phone and it successfully registered in att, and then when i inserted it back onto my hd3, i got the signal LOL.. ..i've no idea why this happened, wish this may help to someone got the same prob.

Have your tried HTC Connection Setup?

yes,i've tried many times
it can detect the right carrier, but doesn't really help

Sounds like you may have to do a hard reset and then reinstall Setup Connection. During the configuration setup after the hard reset you can tell it what region/country you are in now; same for Setup Connection.

thanks for your advice, i just don't understand why should i hard reset the phone. as i tried many roms, each time i swiped in a new rom, the rom was brandly new, like a factory reset, and each time connection setup doesn't work.
i'll take your advice and see if this works out.
btw, i can't see your pic, it's too small. is it something relate to hard reset or ?

no, it doesn't work. T0T

You said your ATT sim works fine... why use the chinese one then? Also i think ATT will give you a new sim if you are under contract with them. You are paying for service aren't u?

………………ok
i almost give up on my hd3...
it seems like a root sin... no matter which rom fits in it, there is no signal at the very beginning when ' get to start' shows..

Is it an hd7? or an hd3? (never heard of hd3)

Found a lost phone

I found a lost Galaxy Note on a bench at a bus stop with nobody around it. I picked it up and tried to call home (to find the owner) and found that the phone had a passcode. I then popped off the back to check the sim and found a vodaphone SIM, (I'm Canadian so it isn't a phone from around here) I've tried a few "tricks" I read online to figure our who owns the phone such as sticking in another sim into it and calling it, then trying to access the phone from there, but all of the ways to bypass the lock seem to be outdated and not work. It is not in developers/debugging mode so I am not able to connect to it via USB. It seems like a pity not try everything to return the phone to the owner. The last thing I can think of is to factory reset the phone, but then I lose all the personal data which sort of makes things.. worse! Help?

Factory data reseting the phone is definitely a last ditch resort and the phone probably will be unidentifiable by then. Did you look at the grease stains on the phone? I've been able to unlock phones with about a 60% success rate just by looking at the grease.

I should have looked beforehand! That would have been the smart thing to do haha.. When I popped the backing of I accidentally wiped the screen so there isn't much in terms of clues from the grease. Is there any way to access the saved emails on the phone? If I could see an email, the to/from email, I could email the owner that I found his phone.

Try googling how to bypass android pattern lock or another similar search term. Something could come up

call VODAPHONE have them check SIM to account
big reward
? PROFIT ??
or..
Finders Keepers...
If I had a GNote I would not be leaving it in public.

Oh that's mine actually....
Not it's not, I jest... Yeah,.call Vodafone. They should know the owner by the imei.

For those traveling international with the S3

Alright not too long ago, I called verizon to notify them about my travels to Japan, 2 weeks prior my trip (i got back less than 24 hours ago). They did some over the phone stuff, added that 100mb plan. And told me to dial *228, I've been warned about dialing *228 on 4G phones before... But this is a Verizon REP telling me this. So i did it, and i was supposed to dial it again when i reached Japan, to update my roaming with their cell towers.
I did so as well... thought little did i know the message i got when i was in japan said my phone did not work over there (didn't know it at the time had my friend translate the message for me days after i already dialed)
Long story short, I've noticed after my initial dial of *228, I somewhat noticed my phone never connected to 4G again. It bugged me, but i was still able to FORCE LTE Only in Phone Info. But when i had that setting in, i couldnt recieve or send calls, or texts... just blazing fast internet.
In my area since I live relatively close to Los Angeles 4G is pretty much everywhere here. What i dont understand why my phone hasn't connected to 4G ever since i called.

I'd pull the sim, reinsert and reboot. You may need to reactivate. Sounds like the rep you talked to was a complete waste of space.

I've tried a SIM pull, no luck. I read somewhere dialing *228 could fry to SIM card? Maybe thats what happened, and i'd need to get a replacement...
What do you mean by re-activate?
I've done factory resets quite a few times already today, as well as the IMEI push/fix just in case... still to no luck

There's another command using the keypad you can use to factory reset your phone...i just can't remember it. Something like *#4342..etc. I remember seeing it posted on here somewhere but I would search for "factory reset" and see what you can come up with.
This is what people did when they flashed an AOSP rom and were unable to get 4G...it could likely work for you also. It's worth a shot!
Here is the thread and the command: Back up all your info because your phone will be wiped and make sure you are on a stock based TouchWiz rom...go into dialer and hit *2767*3855#. Allow it to reboot and hopefully you will have full use of your phone. If not, go and get yourself a new sim card at the local VZW.

Tried that twice during the IMEI push. Still to no avail. I'm going to assume the SIM card got bugged during the *228 process... And would probably need a new simcard. My dad also has the S3, and his connects to 4g just fine in my area... THe things i go through with this phone man... I prefer my bionic if the galaxy's camera wasnt so good.

Sorry about the phone woes but once you're up and running again you will see how this device runs circles around your Bionic.
Getting a new SIM card is easy. Verizon gives them away for free and you can just walk in there. Hopefully you get this taken care of.

Please help me with my pixel multiple issues ,WiFi problems and Oem unlock issue

So a few weeks ago I bought a pixel for my son from someone local. It was very cheap and my son was using it for school using his mobile data. Today I have then tried to use the phone as I await for delivery of another handset and am faced with some issues. First the phone won’t connect to the WiFi. It’s currently running Android 8.1.0 May security patch and no matter what WiFi wont connect. At times it will say saved network but won’t connect. I have tried to reset the phone but alas no luck. The other issue is that phone is sim unlocked and can use my ee and 3uk SIM cards but the oem option states “connect to the internet or contact your carrier”. Unfortunately I cannot get the person who sold me the phone and all I remember is he told me he bought it from Very UK. Any suggestions please to fix this?. I as under the impression only phones which are sim locked have locked bootloader and also any ideas on how to fix my WiFi thanks.

Seems like you've bought a Verizon locked phone. Those phones has locked bootloaders and recently there was a tutorial on how to unlock those bootloaders. So it can't be done on the traditional way. Here's the tutorial: https://www.google.se/amp/s/forum.x...unlock-bootloader-verizon-pixel-t3796030/amp/
You say you're running may security patch see if there's an update first to June. The non Verizon phones got that already on Monday.
Another thing you could try is to do a factory reset and don't restore any backups at all. Because some backups tries to restore previously remembered wifi. So try that and connect to the wifi. If all this doesn't work then you could try to enroll into Android P beta and see if that fixes it. If that doesn't work then it's an hardware defect. If you cannot get a hold of the person who sold you it then I'm sorry to say that's probably why he sold it to you cheap as he probably knew about the problems it was having. I personally would try to get a hold of him first.

hmm many thanks. How do i tell its a verizon device as its currently working with a 3 uk and ee sim card. Am just installing the android P better now and does this resolve the wifi issue because without wifi I wont even be able to follow the bootloader unlock guide above.

Bootloader unlock has nothing to do with carrier. If you could use 3 UK Sim then you're fine. Unlocking bootloader is only needed to flash custom ROM with some exceptions. Are you able to turn on WiFi and see your wifi but not able to connect or does it not turn on at all?

Hi thanks WiFi can be turned on but it won’t connect. At times it says connected and just saves the network. Mobile data is working fine so completely lost, and now trying to flash the P beta.

Just tried android p and same issue. WiFi will try and connect and just end up with saved but it won’t actually connect. Any other ideas please?

Have you tried pressing the wifi name and then press forget and try to put in the wifi password again. Is it the same issue on all wifi? Like at home, school, friends home or only at home? If it happens everywhere then I don't have any more ideas. My thought would be that it's a hardware defect. Is there no chance of getting hold of the previous owner?

They would probably only need the IMEI number, but if it's out of warranty they'll refer you to a repair center. Wish you all the best and hope that they'll be able to fix it. Let us know what Google says if you do contact them. Keep us updated please.

Thanks will update you as soon as I have spoken to them. The person I bought it from did say it was only bought last year from Very UK and it also looks mint. Has anyone had any dealings with Google RMA with phones without receipt?

SIM card not allowed after coming back from Japan

Hello guys,
Im coming at you for a question which I can't have any answer.
I bought a Note10 Plus in October to somebody on the web, the phone was brand new (on its original sealing and packaging) and working perfectly. I was first on Three network, the phone worked, then I switch on GoMo, working perfectly too. On the 10th of November I traveled to Japan with a local sim card (Docomo) and same, all working. But yesterday, I came back to Ireland where I live, and still as of today, the phone show me 'SIM 2 not allowed'.
The phone is unlocked, I've checked with the Samsung support and they confirmed it (but didn't bring me helpful troubleshooting steps). I've contacted my carrier too who said that there is no issue on my account, and they will send me a new sim card too.
I'm not expecting it to work though, as the SIM card is working on the iPhone X of my gf, and her sim card is not working on my phone too. So it's only on my Note 10+.
I've tried to remove the sim and reinsert it, restart it, reset network settings, check the date and time, nothing to do, all go to the same error.
After making research, I tried to check some IMEI Blacklist check websites, but I don't trust them as I don't know where these infos comes from, but one catch my attention because it told me that the phone was blacklisted : https://www.imeipro.info/
All the others says that the phone is clean. Again, that's why I don't really trust it, and my carrier didn't mention any block. I'm still curious why my phone appear as blacklisted so I send them an email to try to know more.
I receive signal too, but can't send/receive calls or text, and I don't have access to data neither.
So now I have my phone with no any SIM working, and I don;t know what to try to get my phone working again.
I think I've explained all I did today, I don't know what to do more, I don't have any idea of what's going on with the phone, that's why I need your light to see if you can help me to find a way.
Thank you guys, I hope to hear from you soon!

From the sounds of it, it sounds like it's been blacklisted, that's my guess. Do you get any message when you insert the sim? I had a similar thing happen to me, turned out the guy I bought the phone off on Ebay didn't pay he's bill and phone wouldn't text or make calls anymore. O2 was the company that barred the phone, and they couldn't help me even though I had proof I'd purchased the phone from the guy, only he could sort it out as it was he's account. Anyway thankfully PayPal came to my rescue, they just needed proof it was blacklisted, carphonewarehouse did a check and printed out the results for me thankfully as I knew the guy that worked there. I got a refund and promised myself I'd never buy a phone off Ebay from a personal seller, if its a business account then maybe. Awful experience though. I hope you get this sorted.
I'm guessing you've never rooted the phone or flashed it as that can sometimes delete the efs folder which causes the phone to have no imei.

Thanks for your answer !
No usually I root all my phones but this time I wanted to keep it as normal, because tthe phone looks like there's nothing more to improve to me (except a little bbit the camera when the light is low..)
I didn't knew that it could cause such things ! I should have done that
Honestly that was the first time I bought the phone to somebody, and more of that, the phone was sealed on the original plastic with the label ''eu sim card only''. So I was trusting it, even if I know, that doesn't mean it's safe behind that.
Since I've posted the message, I contacted few carriers, like mine GoMo, and they dont know anything about the blacklisting (I was surprised) then I contacted Three, they told me that the device does not belomg to the; so they can't check.
I tried Eir, and they refused to give me infos for data protections, which I think is stupid because the phone is not a personal information who could reveal an identity but anyway. I didn't though about Carephonewarehouse, I will visit them because it seems like this is the best idea.
The weird thing to me is still that it didnt worked suddenly... I was in the flight and this is when I came back that it didn't worked. Well, maybe that was a bad hazard.
Something I've discovered yesterday more of that is when I have this issue, turning off the 4G and only allowing 3G/2G will allow me to use the data. Still no phone or text, but the phone is detecting the H+ signal and I'm free to go on the web.
Yes for your question, the issue happened instantly when I insert the card on the SIM1 with the error SIM not allowed, the SIM 2 slot works perfectly, that's what I'm using for the moment but I can't use any SD card at the same time, so it bother me. :/
Thanks for sharing your experience, then I know a little bit fore of what to do. I wanted to go to the police but I don't want to spend 2 hours there. Maybe I'll think of it as a last resort...

I just came from Japan as well I had the same problem but with my Sony Xperia 1.
I bought it from the states and I took vacation to Japan and used their sim card.
When I came back here in Florida I switched back to my at&t sim card I couldn't make calls or texts only data works for some reason I tried everything I used sim card on other phones (sim card is fine)
I tried everything, nothing worked !
I factory reset the phone and it worked, fixed the problem (it's strange because I used Galaxy s8 also with that sim card and it's working fine)
My Sony Xperia 1 had similar problem to yours
I don't know if this will help you to be honest but I had kinda same problem.
Hope you solved you issue.

Thank you for that, I've tried this yesterday after a backup, I used the sim card with the phone completly as new (well, I've restored it from the settings, so I don't know if it was the good way) and it didn't worked.
I think I will try carephone warehouse as jadaress1 requested, it might give me lot of infos there. Im also starting thinking that the phone is carrier blocked, but I can't see any reason why the phone was new and already unlocked so I don't see any reasons...
I'll let you know
