[Q] abroad - infuse can call only emergency - IMEI ok

I bought an infuse 4G in 2011 in USA then, the same year, I brought it with me in Italy, I unlocked it and it worked since then both in USA and in Europe. I deeply love this phone.
A month ago I accidentally broke some pins of the SIMM socket and then I thought to start using the infuse as a guinea pig to play with android and customized roms.
After many issues and trials and many "return to stock processes", I finally managed to have a working CM9 installed on it. It worked so well that I decided to repair the SIMM socket to use it again. I brought it to the repairing shop and I've got it back a few days ago.
Unfortunately, both with the american and italian SIMM cards I can only call the emergency number (911). Basically it can not register to any network. (btw I'm currently in Italy)
To my understanding if I can call and talk to 911 it should mean that the repairing was good.
I also called my provider to see if my IMEI number is blocked for some reasons but they have confirmed no bad records.
I tried returning to fix things following several guides like:
UCLB3_Unbrick_1.1
Odin_UCKE3_v2
No Voice or Data service after install of CM9 - ##72786#
Recover EFS
but I don't see any way out. The problem is still there and it doesn't change, doesn't matter what I do or what ROM is installed.
Unfortunately, I'm kind of lost here because, apparently, everything works and I don't have any error notification (or simply I don't know where to look at to make some debugging)
Do you have any idea, suggestion?
Thank you!

My only thought would be did they really fix the pins? Seems one of them still isn't making contact. Return it to stock then return it to the shop where you got it fixed and say you are still having problems.

i second this but if the shop that you send it to was in the US then its gonna be a while till you get it back but if they end up not being able too then i would suggest buying a new infuse since its about $80-100 on amazon which you would be able to unlock yourself then start from there but yea go to that shop and if they say its fixed try the sim in front of them to make sure it is fixed because returning to stock fixes most if not all issues

I should add that 911 will work whether a SIM card is in or not, valid or not, working or not. Emergency Call is a safety feature that doesn't discriminate (will connect to any network available). This is why telco's ding you with a 911 fee every month rather than charging you for using it when you really need to.

Thank you all for the suggestions

ha! that I didn't know and it changes EVERYTHING!! I thought that being able to call 911 mean I had no problem with the SIMM socket. After whatever you've told me I do believe that most likely the problem sits in the SIMM socket.
One question though: let's say that it wasn't welded well, is it then possible that I can see the SIMM number in the settings panel but it's still not working?

In fact it does say "no service" but I can assure that I can see the SIMM telephone number and I can even launch some of the SIMM card tools (none of them really work though) without having any kind of error notification.

Forgot about that listing. Think I know why. Just went to that page, and I get an "Unknown" for that value (and my phone portion is working fine).
So that's mixed information, but a pin not making contact still covers that issue. But what it could be is that Access Point Names or Network Operators is out of whack (these things can apparently stay the same between flashes - or at least restored backups - for some reason).
To get to these two options, go to settings, the equivalent of More... under Wireless & Networks (sorry, I'm not on stock at the moment), and select Mobile Networks.

So I just have got back my phone from the repairing shop and ... it works!!
So I confirm that there was an issue in the welding of the SIMM socket. So this means that it's possible to see / access SIMM information if one of the pins is not connected.
Unfortunately the guy wasn't capable to tell me much about what they did exactly (don't ask, too long to explain ) so I don't know exactly what was causing the issue but I'm pretty sure it was one unwelded PIN.
It's also definitely true that you can call 911 even if the SIMM is not working properly or is not well connected to the device.

Signal/Network problem

Hi guys,
I've been having this problem with my N5.
Its a d820 model, unlocked and rooted.
I have no signal, cant register to the network either.
I can use wifi with no problem too.
I changed the micro sim card with other carriers, same issue. I asked for a new micro sim to my carrier too (not cut), but still getting the same problem.
It's worth mentioning that the micro sim works flawlessly. Im using it everyday on an HTC One S and signal and data works perfectly.
When I first get the simcard on the N5, it asks for a reboot, after it comes back up, it shows strong signal, but I can't make any call or receive, no messages either.
After a few minutes, the signal goes down and it shows only emergency calls.
Going into mobile networks and searching for my carrier takes quite some time, but no matter how many times I try to select my carrier,it always comes back with not able to register in the network.
I did a factory reset, and went back to stock, and then performed the system updates to 4.4.4.
I flashed a couple of radios as well, but no luck.
The IMEI shows well, and its the same that shows on the box, so I guess no problems there with a corrupt IMEI.
Has anyone else had any problem like this? Any suggestions?
I've been reading some threads here, and I still have to try a different kernel/ROM, but if anyone else knows of a similar situation, I would appreciate any suggestions.

May be it has something to do wid preferred network...
If u use 3g go to dialpad
Type
*#*#4636#*#* phone info
Select modem as wcdma only...
If u use lte select lte only... See if this works

I think I already tried that, but cant remember for sure
Will give it a shot, thanks

Is the phone second hand?
Have you checked if the IMEI is blocked by the network?

sounds like you bought a used phone that has been blacklisted. if blacklisted, your phone wont work on any US carrier, and many Canadian carriers.

Yes its a second hand phone, and I don't know if it is blacklisted on USA, but Im in South America, so that shouldnt be a problem
And there are no carriers here working with N5 so they cant blacklist the IMEI either
(This doesnt mean that the phone doesnt work here, actually, my wife has another N5 that works like a charm here)

the carriers dont have to work with the n5 to blacklist it. in other words, they can blacklist any phone that connects to their network. as soon as you connect to the network, they know your imei and other info about your phone. anyways, they blacklist your imei, so when your phone tries to connect, it cant. the agreement that carriers have in the US and Canada, could possibly be for all of the americas, or, in south america, they could have their own blacklist.

googling, i found that carriers worldwide are sharing blacklists.
The GSMA, an international association of wireless carriers, also keeps a database that wireless carriers worldwide could check to prevent stolen phones from being reactivated on their networks.

yup, thats the best thing to do. the people that first answer the phone, customer service, probably wont be able to help, maybe someone in tech. or, use this website to check(there art other sites as well).. http://swappa.com/esn

Well I just checked. IMEI not blacklisted on my carrier, also checked with swappa, not blacklisted either.
I used the *#*#4636#*#* to select wcdma as well as other options there, but still no go.
Also, under Mobile network settings, changed the preferred network type to LTE, 3G and 2G, but no luck
Tried Choose automatically the network, but still getting the message that its unable to register to the network right now and that I should try again later
I guess Im left with flashing some other ROM/kernel to see if it helps, unless someone has any other suggestions

also, what kind of nexus 5 is it, a d820 or d821? it would make a difference signal-wise. ones for north america, ones for europe. honestly, i have no idea which you would need http://www.phonearena.com/news/Differences-between-the-two-Nexus-5-models-D820-and-D821_id48985

I don't know if the problem is with the carrier, since I'm using the very same simcard with another phone and I have data and network with no problem.
The phone is d820, but I know it works here (my wife has the same one), network 2g and 3g work well here, LTE is the only thing that won't work here with this phone but I don't care about that
I'll keep looking just in case, and I guess tomorrow I'll flash different ROM

If the problem is wid radio flashing a different rom won't matter ..
Have u tried flashing a factory image ?

I know flashing a new ROM wont help with radio, but I've seen that using *#*#4636#*#*, going into phone information and then Select Radio Band, gives me an error and force closes.
I've seen some threads about that, and someone saying that it was working on a CM ROM, so I was thinking of trying that in order to be able to select the radio band and see if that helps.
About the factory image, yes, I used the google images to go back to stock, and then performed the system updates.

Well I flashed Slim Rom, and was able to get into *#*#4636#*#* to change radio band. Tried them all, no change.
Played around with the preferred networks and no luck either.
I'm officially out of ideas, but I'll keep digging around to see what I can find.
Any suggestions welcome.
Also, I know that there is a known issue with the GPS signal on some Nexus 5, and there are a few videos on Youtube showing how to fix it (basically opening the back of the phone, and sticking a piece of paper under the connector).
Does anyone know if there is something similar happening with the radio? Does anyone have a photo of the phone showing which part would be the antenna?
One additional thing I noticed.
If I switch, or just take out and reinsert the micro sim, the phone asks for a reboot. After doing that, when the phone boots up, I see I have network (full bars), going into mobile operators, I can see my carrier, and I can register too. But I cant make or receive any calls or messages.
During this 10 minutes that I have this sort of fake signal, if I go into *#*#4636#*#* and phone info, I can see my carrier, but it doesn't show my phone number. Weird.

Lg nexus 5 network issue
i am facing the same issue with exus 5 .In my hometown in India,the phone simply shows "Emergency calls only" and shifts to normal working mode with full network coverage once i travel to other parts of my state (parts which probably has a better signal strength ,i dont know ).i have tried out changing the sim card and a factory data reset ..Both didnt help ..

[Q] OPO on T-Mobile - 2nd OPO, same problem - network connection issue

Hello all,
Back again.
I'm trying to get my "2nd" OPO to work on T-Mobile USA.
First of all, it is not a SIM issue. I have 2 microSIMs that can be used freely across all T-Mobile enabled devices.
Once I try to connect to T-Mobile, it gives me a "Your SIM card doesn't allow connection to this network".
I tried the 'unlock the basebands/LTE process', got as far as ADB talk, but I cannot execute the su command, so the setprop does not work.
And this is my 2nd phone, a replacement from OPO. 2nd month running already. The 1st one had the same issue, but at the time I did not do research on tinkering with it,
and was 'NAIVELY' believing in OPO's customer 'service'.
Took me 2 weeks just to get 2 basic replies of "tech support", which didn't help since they gave me rather weak tech suggestions - 1st suggestion was reset, 2nd suggestion
was to look at the T-Mobile thread (I cannot connect to network, so how do you expect me to connect to APN?!?) . Then took them 3 weeks to go through the RMA process,
and yet another 2 weeks to send me a replacement(not).
Any assistance appreciated.

Check your imei on the tmo compatibility site. It could be blocked. Dumber things have happened. Double check that the SIM is installed properly. Second replacement and multiple sims seems to point at something you are doing.

Yes, the IMEI is not recognized on t-mobile. Which is stupid since this is the second one (the 1st one had the same issue too).
Has anyone else gone through this frustrating experience? To have two OPOs whose IMEIs are not recognized is...... well.... $!%#!. :silly:
SIM installations are fine. I have done them multiple times, with the same results.

Unfortunately no. Second OPO, same issues again. IMEI is not supported either. So, Groundhog Day here.

I'm with you man. I left vzw for T-Mobile and struggled like hell with getting the OPO working properly on it. From loaner phones to multiple sims, they/we tried everything. End result was to leave for at& . The signal is strong, but yet I keep missing calls daily. This beauty is going up on eBay. I just can't take it anymore. Sucks because Dev involvement is Huge here

Register and activate your phone with T-Mobile... I had the same issues for MetroPCS, and that fixed it.

I dont have any issues with network on Tmo, but what do u mean by register and activate ?

What I am saying is, you need to contact your carrier and get your IMEI entered into their system in order for the phone to run all services correctly on your carrier... whether it be T-Mobile or anybody else.
My 1+1 ran most of the services and operated on my SIM card and phone number in my hometown area. But, when I went to another area or town, it would not register with or run on any carrier... NONE! not even roaming like it does at home. I had to go to MetroPCS (on T-Mo network) and get my phone activated onto their system for it to run data, and 4G LTE. By just inserting the SIM card does not automatically sign your phone into the system and you should call or go to a dealer store and get it turned onto your particular carrier to run the network correctly.
Hope this clarifies my statement.

I never had to register or the like with my OPO for t-mobile. Didn't have to with my wife's OPO either.

It's a common enough issue across carriers. Sometime you do have to register the phone, and make sure you have the correct APN settings.
I just gave my daughter my OPO, I had Consumer Cellular (ATT) SIM in it. She dropped in her T-Mobile SIM and off she went, working perfectly. She's been using the phone about 2 weeks now, and in response to your question, I just checked her aPN, since I knew it's been working perfectly for her, only to discover the phone pulled in a MetroPCS APN! It's been working so well, she doesn't want me to change it to the T-Mobile APNs that are in the list.
Here is her APN settings (Calif-San Diego area), MetroPCS
name MetroPCS LTE
apn fast.metropcs.com
MMSC http://metorpcs.mmsmvno.com/mms/wapenc
mcc 310
mnc 260
apn type default,mms,supl

What APN is you OPO set to?

I had just popped in the SIM card and it did work in my local area. But when I went outta town, my phone wouldn't connect to any services, no roaming either. I use MetroPCS on T-Mobile network, and nothing would run without activation on their system and registering the IMEI. So, results may vary depending on the carrier or area.

registering
I am a frequent visitor to the USA from Canada. Usually with my original Samsung or Nexus rdware from Canadian carriers, but unlocked.
Each US carrier has insisted on registering my IMEI prior to activating a SIM. It seems to the user you can pull a SIM and place in any old device and most times, no problem. But that's not the carrier approved method.
T-MO was very insistent on this. To the point they would not activate a SIM for me with out the device and the IMEI first
Hopefully registering with your carrier solves this. It's a thing and may be the point of issue for you.

T-Mobile Note 10 Plus 5G

I unlocked my note 10+ 5g from t-mobile, but it won't get service with verizon.
When I install a non-tmobile sim, the software does not switch from tmobile for some reason.
Also Sam Mobile only has t-mobile and metro pcs firmware availible for the sm-n976u
Does anyone know if there is a way to get the phone working with verizon? Thanks.
-God Bless

Try clearing Sim card tool kit data.
Network reset.
Clear system cache.
Edit Access point names to correct values.
That's all I got but sure there's more. Never had use more than the above but never changed carriers. Verizon advanced tech support should be able to help... AT&T would.

The Verizon Note 10+ 5G has a different model number. So they probably won't allow the T-Mobile/Metro/AT&T version on their network

I think you're correct. AT&T is compatible with Tmobile but not Verizon according to B&H Photo compatibility charts.
So it look like AT&T is in your future. AT&T is easier to deal with anyway. Do not use a corporate store though, use over the phone or online AT&T.
It may be possible to change out the C port PCB for the Verizon variant. Yes that PCB controls internet access. I can't confirm this is the only difference though! That PCB is only $20 and relatively easy to change out.

It's gets service with att, but it still has the tmobile boot logo. I flashed the att rom, but it didn't help. The carrier is supposed to automatically switch when you insert a different sim card right?

It's actually super difficult to hard brick a Qualcomm device, and even if it is hard bricked and only enters EDL mode, it can be fixed as long as you have the correct files.
There are too many safeguards in place between Qualcomm and Samsung - the average user will always be blocked from doing anything that would brick a device. There's really no danger in flashing firmware whatsoever

I may have a way to do it. No guarantees though

I'm guessing the only option left is to root the phone, and then start manually removing things.

My method doesn't involve root, no. You can't root if you've taken an OTA update in March of this year or later

I hope I can be of some help.
I recently ordered a Note 10+ 5G - Locked Verizon from a popular online re-seller. When I turned it on, I was greeted with an AT&T boot logo. I was pretty upset, but I though I'd try to get it up and running on Verizon before spending a couple weeks sending it back and getting a replacement. I tried Verizon's online software and I couldn't get beyond the IMEI change. It kept telling me that the Note's IMEI was what I was already using with my Droid, which was obviously not the case. So, I headed into my local Verizon store.
Nothing they did would get my 4G SIM to work, so they swapped out for a 5G SIM for free, then switched my hardware IMEI numbers and proceeded to have a some difficulty getting on the network. After doing a network reset, it seemingly worked. More on that below. I was getting both data and voice over network. I was able to transfer my setting, apps, etc from my Motorola Droid with Samsung Switch. The phone indicates both 3G and 4G signals as I travel around town. 5G is not available in my immediate area, though it is in some cities I occasionally travel to, but I'm unable to test that just yet. I become aware that there are differences between Verizon's 5G and other networks and it seems the non-Verizon phone I have is probably for the best in terms of compatibility.
Unfortunately, texts frequently take 10-30 seconds to send. Images, gifs and other non-text MMS can take multiple minutes to send and sometimes just fail. Other times the recipient will receive them twice. I feel like this may be due to the poor coverage at my residence. Further testing in areas of good to excellent coverage are necessary. I tried changing the network settings from Settings > Connections > Mobile Networks > Network Mode, but anything other than the default "GLOBAL" would result in a disconnect of data and voice services. The only way to fix it was Settings > General Management > Reset > Reset Network Settings. This would restore the Mode to GLOBAL and bring back data and voice services.
In an effort to remove the AT&T branding, I learned how to trigger a carrier switch, dialed the code and changed it from AT&T to XAA. That got rid of the AT&T boot animation and I was able to remove all but 2 stubborn AT&T apps. I noticed that my android version was 10 and UI was 2.5, so I set out to update.
This is where things got frustrating. Every attempt to update through the settings > software update was met with failure. Try again in 24 hours, it would say. I assumed this was because I was now using a Verizon sim on an AT&T firmware, but I wasn't sure. I thought I might be able to flash to a Verizon firmware, but after several versions and some more research, I learned that going from 976U to 976V was not possible.
So, over the course of several days, I learned a lot. I looked up the firmware releases on AT&T's website for the 976U and saw that they matched the T-Mobile and MetroPCS versions. So, I settled on a T-Mobile version of Android 11 / UI 3.1. It updated without any issues and even remained in XAA mode. No bloatware, no loading images, all settings and apps the same.
So, even though I have an unlocked AT&T Note 10+ 5G 256GB and you have a T-Mobile, the fact that we both have a 976U model, I think there is hope for you to get up and running on Verizon.
Hope this has helped.

Unlocked or not?

I got a Metro by T-Mobile phone unlocked on eBay and while the phone no longer rejects MVNO sims, it won't connect to any network either. It still connects when I put the Metro sim back in but it won't connect with sims from Lyca, Tello or Hello Mobile, all T-Mobile MVNOs. The phone is a TCL 30 XE 5G (T767W) and I bought two of them new and they both have the same problem. I'm new to the T-Mobile network and I don't know if I'm missing something. I've never had this kind of trouble on Verizon or AT&T. Has anyone else run into a problem like this? I appreciate any help anyone can offer.
Thanks!

According to that site my phone is unlocked but it still won't connect to any network unless the original Metro sim is installed.

Maybe you need to enter service menu and change your radio settings or maybe you need to flash a different modem for your specific model number.
I know you said you bought them new but can you confirm that their IMEI is intact?

Thank you for your reply! Both phones were shipped to me from Metro by T-Mobile. The phones were able to connect with an MVNO sim when I set the radio to 2G only mode but that option disappeared when the phones updated to Android 12 and now they can't connect at all. Even before the update, the phones would frequently disconnect and I had to set them back to 2G only mode to get service back so there was always something wrong. I'm pretty good with computers but I've never flashed a phone before and I've been suspecting that I would have to do that with these phones. I'll be happy to check their IMEI numbers if you could let me know what I'm looking for. I'd also like to learn more about flashing a new modem as you mentioned above that sounds like it might address the problem. And if you wouldn't mind letting me know where I could find the service menu?
Thanks in advance!!

After they updated, have you tried booting into recovery and wiping the cache partition(not factory reset)? Sometimes, after updates, wiping cache is necessary to remove conflicts between previously existing data and the new update.
If you are getting a connection of any kind then your IMEI is fine.
Flashing a modem is sometimes necessary but it can have risks if you flash the wrong thing.
I'm not familiar with TCL devices or how they are flashed. Typically, to flash a different modem requires downloading a firmware that has the modem that you want/need then extracting the modem from the firmware then flash the extracted modem onto the device.
Methods to access service/radio menu different from device to device, I don't know how it is done on TCL devices. Most of the time it is done by using your dialer and dialing a specific code, if there is a dialer code for your device, you should be able to find it with a Google search for:
"TCL 30 XE 5G dialer menu code"
Or
"TCL 30 XE 5G service menu"

I was able to find my phone's service mode or engineering mode (hope they're the same thing) and get service back by setting the phone to 2G only mode again but that doesn't solve the problem of it losing service when LTE or 5G are turned on. Are there any other settings I could try changing?

Can you use the service menu to find out which bands/frequencies and network type the current modem/radio is using?
Can you find out which bands/frequencies and network type that your carrier network is using?
Compare them to see if they are compatible.
Or, try calling customer support for your carrier, there may be something they need to do in their system from their end to get your device to connect.

What do you mean by network type?
There are a lot of options to choose from, several of them list bands. Is there a specific menu I should look for?
The carrier I have the phone on is Tello which is a T-Mobile MVNO. I've also tried Lyca and Hello Mobile both are also Tmo MVNOs and all three had the same problem. The phones are from Metro by T-Mobile so everything should be compatible. Tello customer service has tried to help but they can't figure it out.

But, are the bands that are presently available on the device within the range of bands that your carrier uses? Do the network and the device use the same bands? If so, you shouldn't need to flash a different modem, if not, you may need a different modem.
Did you boot into recovery and wipe the cache partition to remove any potential conflicts caused by updating to android 12?
Are you certain that the SIM(s) you are trying to use is/are valid and active? If they have been previously deactivated, they won't work
Don't skip through my posts and only answer part of my questions. Let's cover the bases without skipping an answer to a question. Otherwise, it could lead to a wild goose chase that could have been avoided by answering everything I ask.

Sorry about the confusion. I did wipe the cache and in the past I've done a full factory reset from recovery mode it didn't help. And this problem already existed before the update to Android 12. It started the moment I changed sims. The phones only ever worked right with the original Metro sim and still do. That's why I wasn't sure if they were unlocked right but they don't reject other sims either.
The sims are active and have never been deactivated and now that I can force the phones back into 2G mode again, I can make and receive calls and use 2G data.
As for the bands I'm finding in the service menu, this is where it gets weird. They're all selected, there must be over a hundred bands turned on including bands I know this phone doesn't support.
I have confirmed the phone supports all the same bands that Tello uses. Tello uses the same bands as T-Mobile.

Ok, thanks for confirming.
It is weird, everything seems to be in place. Have you made sure your APNs(Access Point Names) are set correctly for the network?
I can't be certain that you have all of your network and radio settings set correctly because I have no idea what settings you have, what the options are or if there are any tucked away somewhere that isn't obvious.
If everything is right on your end, it may be something on their end that they need to get right.

Yeah, the APN was the first thing I checked and Tello confirmed it too.
I can send you screenshots of the service menus if that would help.
Tello is now saying the phone might not be "fully unlocked" I don't know what that means. Is there more than one way to lock a phone? Did T-Mobile come up with another way of locking their phones? A screen in the settings menu does warn the phone is still locked and it isn't yet eligible to be unlocked but it accepts the sim and connects to 2G at least. Could Tello be on to something here?

There are couple of different kinds of "unlocked"
There is SIM/carrier unlock and there is bootloader unlock. They two completely different things and have nothing to do with each other.
Have you tried going through the carrier unlock process yourself to confirm it has been done correctly?

Generally, there is a website that you go to to get an unlock code.

My understanding is that Metro phones can't be unlocked with a code. Instead, they're unlocked by a preinstalled carrier app when the phone becomes eligible for an unlock, which my phone isn't. In my case, I bought an unlocking service from eBay which had me hook up my phone to my PC via USB for the unlock. Is there another way to check?

You got scammed, whether they did it on purpose or not is another question. They probably didn't rob you on purpose, it is just a matter of there never being any kind of guarantee that a 3rd party unlocking service works on every device. You took that chance when you chose to go that route.
If there is an app that is supposed to be used, why is your device not eligible to unlock via the app? You will have to use the official unlock method if/when it is eligible, hopefully the 3rd party unlock service hasn't done anything that conflicts with the official method.
I suggest that, in the future, don't make gambles or look for shortcuts when buying devices without being 100% certain that you are buying from a reputable source that guarantees their products and services. It is best to buy directly from the carrier/manufacturer or from Swappa. I wouldn't buy from eBay unless I could confirm that there was a legitimately proven unlock method for the specific model number that I'm considering purchasing before I actually purchase the device.
If you can return the device and get your money back, I suggest you do it or report it to eBay to see if they will protect your purchase since what you got is not what you agreed to purchase.

I got the phones new from Metro not eBay. The only thing I got from eBay was the unlocking service which cost me $8. And I didn't pay anything for the phones either as they were free with the purchase of one month of Metro service. So there's really no point in returning the phones and I'm not gonna bother opening a case with eBay over $8.
Metro won't unlock the phones until I've paid for six months of their service.
A quick search on eBay comes up with multiple sellers offering unlocks for my specific phone model locked to Metro. I've been thinking about just trying to get the phones unlocked again by another seller but everything and everyone seems to be telling me the phones are already unlocked so I don't know what I should try next. Is there a way to check if the phones are really unlocked?

You've already used methods to check if it is unlocked. Obviously, the service you paid for didn't work, you can't get your money back for that, those services don't come with any guarantee. As I said, you can take another chance and try another 3rd party service that also is not guaranteed or you can wait and do it the official way. I'm betting the unlock service is a waste of time and money and you'll have to wait and do it the right way. That is the cost of blindly taking a shortcut.
