help to unlock XDA Exec

Following Buzz's installation instuctions I am stuck with these two items.
9. Activate Radio even without Sim in it saying something about no Sim)
15. Flash your original Radio ROM. Do not upgrade the bootloader until you restored an original radio rom.
I think I am just about there with number 15 (with the resource on this site) but can not find anything on #9.
I know a lot of people say that it is already unlocked, but it seems unlocked to a few networks.
Regards

hi, XDA Execs should be unlocked
Does it ask you to enter the unlock code if u enter another sim?
If it doesn't then it's unlocked as far as i know.
What makes you believe that it's locked to a few netwroks, maybe it's because you're trying to find a non-existent umts signal...
Turning the radio on means turning flight mode off (and for the purposes of unlocking you do that without a sim)
Hope that helps.

I take it the UMTS is another name for 3G. My BT account is a normal non 3G account. Is it a case that I need to alter some of the settings, the networks it lists are...
@VF-UK
@ O2-UK
@ Orange
Is ther anything I should try....

umm, what happens if you insert a non-o2 sim into your phone?
If it's continually searching for a signal, it might be trying to search for a dodgy 3G/UMTS signal
in which case try going to phone settings, then in the band tab , select GSM instead of auto or wcdma
In the worse case scenario, if/when you flashed the radio 0.00.00, you might have had some problem with your USB (See the unlocking thread)

Thanks for all your help.
I think I have now got to the bottom of this. The fact is that BT use the VF network. The phone logs onto this, so I guess this is normal. However the signal strength never gets above 2 bars, is this normal?

Not anymore, dude. BT sold BT Cellnet (now O2 plc) a little while ago, but now they have started their own mobile service again (called BT Mobile) BUT piggybacking Vodafone's network.

If you want help, you need to tell us more details, such as what software/firmware version you are using, network carrier, what actually happens when you get no service, if it's rooted, etc.
Basically, the more information, the better.
Anyways, I have that random no service with the Australian Optus network, even though it says on the phone that I have full bar reception. Sometimes it's just the network.

"Not allowed" suggests a SIM problem.
Either the SIM has gone bad and you need to request another one from your network, or the SIM connection on your handset is dodgy.
The SIM governs what you can and can't connect to. If it's not allowing you to choose a network then it's not reading the information from the SIM properly.

even with the new sim the problem persists

1.29.401.12 and the newest 2.17 update have new radios i hear
maybe that will fix the problem,
thats my next step.wait for the ota

already changed SIM card and anntena
but nothing changes
i have sense 4+ (i thought the new update will fix this)

No network issue after repair

Hi there,
I recently sent my phone back to HTC because my volume button was stuck, which resulted in it not being able to boot (as it always went straight to recovery). They repaired it, and after three weeks without my phone I know received it back. They 'replaced parts and did a software update.'
Problem is, now I have no mobile network connection. The phone recognises the SIM fine, but no signal and search networks results in "Error while searching for networks."
I'm blaming the software update HTC did, so I send them another email. The thing is, I don't want to send it back AGAIN, I had the phone a full 2 weeks before it broke and haven't been able to use it since. Is there anything you guys can think of that doesn't involve rooting it and losing my warranty (which I will probably need now)?
Thanks a bunch

Hello,
have you tried to switch between the network mode; only WCDMA or only GSM? (Settings->Mobile Network->Network Mode)

Thanks for the reply. Yes I have, no effect. One other weird thing I have noticed since first posting: at the about -> Phone Identity screen, the phone number does not match my actual sim phone number. It reads the SIM fine though, as all my SIM contacts are available.

Could you use/try another SIM Card to check its work with a different one?
Is WiFi working? Any interruptions druing a regular call?

Regular call is impossible, as I have no cellular network at all. Wifi works fine. I am currently unable to try another SIM, as I'd have to cut a microsim out of a regular one and people around don't want to have their card cut up.
The sim works fine in my old nokia though, so I don't think that's the issue.
I'll try to find a friend with an iPhone 4 to try their microsim, but I'm not really counting on it.

Weird network issue... no network when switching to 3G/4G :(

I am in a fix here!!! Since long I have been facing this problem wherein, whenever I switch to 3G/4G mode, my phone looses network forever.. It seems to work perfectly fine in 2G mode.. I tried everything.. playing with radios, factory resetting and all the other help that I could get but in vain. I thought it is a hardware issue and since mine is an imported one, and I don't have warranty, I was avoiding to take it to a repair centre.. A week back, I went to Malaysia for a trip, and as I put a local SIM, my 3G starts working perfectly fine... I thought it could be a radio issue and as I came back to India, to my surprise my old local SIM was working fine in 3G mode yet again!!! I thought somehow my problem was sorted!!! It worked for 2 days and it is back to the old problem now.. no 3G whatsoever!!!! Please help me guys!!!

I was just browsing and I read an samsung user facing the same problem.. The carried switched his normal SIM to USIM.. and it started working.. could this be a valid issue?

try this.

If changing the settings in Phone Info did not help I have to agree that you need a different sim or different APN settings.

The same SIM works with the same APN in other phones... and even if it was an APN issue then the data would have been a problem.. But i don't even get network in 3G..

Post as much detail about your problem, if you want to get help.
What version M8?
Is it modded (custom ROM, root, s-off) or stock?
What region/carrier, and more importantly, what bands used for 3G and LTE?
What does it say for OS number in bootloader screen?
You've verified the SIM works for 3G and/or LTE on another device?

According to the following webpage, the 3G band used by Airtel is Tanzania is 2100 MHz (900 and 1800 listed are only for GSM/2G): http://www.worldtimezone.com/gsm.html
As this webpage also lists " 4G LTE TTCL" I will have to assume you got the info from the same or similar website. And that doesn't tell us what band your carrier uses for LTE/4G.
The 3G band 2100 MHz is supported by your current firmware. Make sure you have properly input the APN info for your carrier in the phone's settings.
LTE is trickier. Even with the proper band support and APN, you might not get LTE using an M8 version not intended for your region/carrier. But 3G should be possible.

I did but the 4G symbols is showed on the network bar once in a while. And it does not last long when it shows up!
For the TTCL sim card i can not access the network at all since it does not allow 2G services!

The same here. I face the problem yesterday =)) LTE icon show for the first time and then after a reboot, 3G and LTE signal gone forever =)) Now Edge only. Trying to fix it.

Help 4g

Hello friend, i bought a new m9 and when i activate data mobile i have only 3g , i tryed factory reset, to setup my network,
I rooted my phone, installed custom room.. still no change.. anyone can know why ?

Well maybe you dont have great 4g signal in your area? Or change apn.

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.

at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.

Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything

Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.
