[Q] Help with unlock

To state clearly at first. The new phone in question was not rooted when I purchased it, but I did root it. So the phone is rooted but not unlocked. I thought I should also add that I'm in Atlantic Canada.
As usual, I always seem to have an issue that I look and can never seem to find the answer. This leaves me asking a question that I'm hoping there isn't already an answer to because I know people hate that.
So here goes. I have 2 SGH-989D phones. One I got new 18 months to 24 months ago with my re-negotiated Telus contract. I got the second one "barely used" a couple of months ago and I'm pretty sure it was a Bell pay as you go phone as this is what the person told me. He said all of the phones they get are always Bell. He would have no reason to not be truthful especially since I had a Telus and he knew I would need to unlock it I purchased it because my existing phone was acting up and also the screen was pretty severely cracked.
What I found odd is that when I put the Telus SIM card in the phone, I didn't get any message that the phone was locked. I was immediately able to dial a number and the call went through. I could also send and receive txt's. The phone also says Telus at the bottom of the screen. What is problematic however is that 4g won't work. When go into the new phone under network mode info this appears "GSM/WCDMA(Auto Mode)" But when I look at my original phones network mode I get "GSM/HSPA(Auto Mode)" So, I'm thinking this is probably quite obviously the reason that 4g isn't working and I have no data available unless I connect to wifi. This won't do.
So, where do I go from here? I'm thinking i need to unlock the phone in order to do something about this probably? Or is there something else I can do to pick up the HSPA instead of WCDMA? I'm so irritated by this. It feels like it should be a simple fix since both of these phones are SGH-989d's but maybe it's not. Lastly, and I don't think this makes much of a difference. My old phone is 4.0.3 version and my newer one is 4.1.2.
Thanks and I'm hoping someone knows what or if I can do anything or if I should just give up. I really hate giving up so I'm hoping it's not the latter of the two options.

Moved to Q and A, and, please do not bump within the same 24 hour period.

The phone is unlocked or you wouldn't of been able to make calls etc with your sim.
My guess as to the problem is that your Bell phone is not a SGH-T989D, it's actually a SGH-i757M or GT-I9100M, they are called Samsung Galaxy S2's but there are a few models of the S2 out there. To verify your model either go to Settings > About phone and check Model number, or pull battery and look under it for the model number. To my knowledge, Bell has never sold the SGH-T989D model of the S2.

Thanks for your reply Almite. Unfortunately the phone is the SGH-T989D.. I know it's a weird problem I've got here.
I used to play around with satellites back in the day. One of the things we used to do with the boxes was to jtag the box, erase the memory from the primary chip and then flash it with a different STB's info. This would enable us to do some wonderful things.
Rooting and then unlocking seems like a similar process however I just don't want to flash the phone with something that is going to brick it. I guess I'm going to need to do something. This phone is no good to me this way. If I brick it, I brick it. What I would like from someone in the community would be to direct me to the easiest process to flash my phone with a telus ROM.
I have read A LOT and there are many opinions out there, but I'm thinking that there is probably a consensus on what is the best and easiest way.

Update
I have successfully installed Jedi Mind Trick using TWRP as it appeared to be the best stable one out there. Used Darksides superwipe and then installed JMT. Still have issue of GSM/HSPA on original phone vs GSM/WCMDA on the phone that now has JMT installed on. I must say, I'm pretty impressed with how easily it installed and the ROM itself however sadly it did not help my conundrum.
I'm thinking that there is probably a developer here up for a challenge that could probably assist me with my problem. I really would like to be able to pick up 4g on this phone, or It's pretty much useless to me. What I need to figure out is how I can change this phone to recognize the HSPA network instead of the WCMDA network as GSM does not appear to be relative to data. Not with Telus anyway it would seem.
Maybe this isn't even possible because it's hard coded into the phone or something. Anyone have any ideas?

Last update unless anyone has any ideas

Spent almost an hour on phone with Telus tech support. he explained that WCMDA should work fine as that and HSPA are essentially the same thing. Went through several settings changes and edits with him. In the end, he was stumped. The changes we made should have worked but did not. Therefore I supposed I have no choice but to give up. Guess I'll give the phone to my daughter as i don't want her to go online without wifi anyway.

Same issue
My wife recently cracked the screen on her Rugby Pro so I picked up a slightly used Koodo T989D and plugged in the SIM card. I had the same thing happen. Phone booted, made calls, all seemed well. The next day she realized she had no data connection. I rooted the phone, flashed Telus radio, tried different ROMs, even purchased the unlock code for it hoping for a fix. I can't seem to find anything that will allow this phone data connection of any type other than Wi-Fi. I would really appreciate any ideas or information that anyone has on this topic as I'm running out of ideas and buying another replacement isn't an option.

So I hunted and finally answered this question we both had. Go to Settings:Wireless and Networks:Mobile Networks:Access Point Names.
Since my phone was a Koodo phone it lists Koodo SP. Click the menu button then New APN. Name it whatever you want. I called it Telus. APN is sp.telus.com. Scroll down to MMSC and type http: // aliasredirect. net/proxy/mmsc (without the spaces. They won't let me post a 'link'). Under MMSC proxy type 74.49.0.18. MMS port is 80. MCC is 302. MNC is 220. APN type should be Internet + mms. Click the menu button and save. Click the circle behind your newly created APN and wait. In under 30 seconds I had 4G connection.
Hope this helps you.

Does Flashing Stock Firmware Tar trip KNOX on the Note 4?

I'm having issues with my phone reverting to 3G after only being on LTE for a minute no matter how good of a signal of LTE I have. This just started today, and I have refreshed the profile, prl. I had the Sprint people remotely update my phone, and they also checked for issues in my area and there are none. I also factory reset/data wiped my phone and it didn't help either.
So before I call Samsung and tell them my issues for a replacement I wanted to try installing the Factory TAR via Odin to see if that might fix it since I guess factory reset may not really touch any corrupt modem/radio files really.
I know that on the Note 3 it didn't trip it, but I was wondering if someone has had the chance to do this yet on ours to see if it tripped it?
I might call Best Buy and tell them my problem and see if they will switch it out for me even though I am out of the 14 day return window. I really don't want to send it back to Samsung and wait a week or more for a new phone.

I don't see why it should you are not flashing a custom Rom just the original firmware stock. Your KNOX is in tact now your not rooted your good to go:good:

don't quote me, but I think Knox is tripped when change to a custom recovery, which is what is needed to install a custom rom.
Unless you're rooted, you should be fine. If you are, you've probably already tripped it.

flashing stock tar
Did that fix your LTE issues? Im having the same issue.

Nothing you can do will fix the LTE issue. Sprint says it is a Samsung issue with the phones radio firmware and Samsung says it is an issue with the their towers not connecting to the phone properly. I am on my second note 4 with the same issue after Sprint swapped with me. On second phone I went around with them for a week. Finally got to talk to an advanced tech supervisor and he said according to some log only he and others at his level has access to Samsung has said that some Note 4 phones had been flashed improperly. Note by flashing I mean the use of JTAG equipment not some OTA or USB thing we can do. So Sprint advised me to contact Samsung about sending the phone in to be reflashed.
So begins my third week playing phone tag and on hold for 30+ minutes at a time. Finally Samsung admits there maybe an issue with the phone since it happens all over the DFW metroplex. So they tell me to send it in. I ask what the turn around is since it is my only phone and I can't be without it for 2+ weeks. So the Samsung says "I see you are in the Dallas area, just a moment" puts me on hold for another ten minutes. Comes back saying I will email you a service ticket you can print out and then carry it to our service center in east Plano.
So I did that, had to leave the phone with them for 2.5 hours. Went back and they said there is nothing wrong with the phone and that it was reflashed per Samsungs support request. Tested on my way home and got 30's near the repair facility, then down to 10's and singles. About half way to Carrollton back in to the 30's, then back to the singles or lower near my apartment. Just a 1/4 mile north of my apartment I can get 50's.
So neither is willing to offer a solution or even a cause and we are stuck between them. Tomorrow I am going to the Samsung store in Frisco and asking if they can do a swap for an S5 or something. Something to prove that at least Samsung still believes the customer is always right and to keep the customer happy. I am not going to hold my breath though.
Basically one of them dropped the ball on the version of the note 4 and neither wants to take the blame or the backfire that will come from it once made public.
In my case it looks like I am stuck with 20 more payments on a defective phone unless the Samsung store is willing to do something.

[Q] IMEI 0 but Network is Live

Hey Guys!
Yesterday I bought an LG G3 D855 32/3 from second hand.
It's already running a Custom Rom I don't ask to restore it couse I'll bump the bl right after the buy.
Today I check some thing and I see my IMEI is 0.
But I have a network conenction. Gsm, 2G, 3G and 4G too.
What does this imei 0 means for me?
This is for the custom rom?
Can I backup this efs ?
Can I loss my network If I switch rom?
Regards!

This happened to me on my d851. Unfortunately the IMEI is corrupt, but I was able to recover. After that, I made sure to back up my EFS. If you google "lost imei lg g3" you can find info on the recovery process with a little reading. Anyway I'd make sure you have the original IMEI still under the battery before proceeding. You also might want to check the IMEI to verify it is clean.
Do note, though, methods of writing the IMEI or supporting such are allowed on xda, though.
To answer your question on ROMs. When I had a 0 imei, I was able to connect to providers (att / tmobile) on multiple roms including stock. So in my case, it was just a nagging knowing it was 0. No ill effects. Your experience might be different, though.

I have the same problem with my d851, IMEI shows 0 but i am able to make calls, text, browse,2g,3g(Havent tried LTE yet). How do i get my imei to display.
Its not a problem tho as i am able to connect to network but it will be nice if it displayed.

It's only a problem if you resell. You have two options.
1) Contact LG and tell them what happened was a bad flash and hope they will allow you to send it in to get fixed.
2) Do it yourself, as I did. This cannot be discussed on xda because it could be used to change an IMEI to one not assigned to your phone. I ill say it's possible and using the software required is a legal grey area, but I technically DID sign an NDA with Qualcomm during the time I fixed my phone. Work reasons, so it may not have covered it, but still. Also there seems to be one version of the stock ROM that works with the software. for D851s that is.
Edit: The problem is the EFS got corrupt. If you fix this by all means BACK UP YOUR EFS and store it 100000 places

Very good advice indeed!
Had this problem with my G2 once

But as i have read in the past, replacing your imei with one that doesnt belong to ur device should cause a hardbrick. Also, i dont live in the US, i bought the D851 from a phone market i think it has been refurbished.
THis could mean that the imei at the back of the device might not belong to this device (I dont really know... at least, thats what friend suggested.) I checked IMEI.info for the imei at the back and it turned out with a no results. Then i checked it on the T-Mobile site and T-Mobile said the device has some bills and if the bills are not paid, it wont be able to be used with T-Mo.(I dont really care as we dont have T-Mo here. But atleast T-Mo recognizes the imei.) THen i checked the imei with one more imei database and it showed up.
Now, my problem is that i know of Qualcoms Program that allows the IMEI to get reassigned but i was wondering that was for devices that are not able to connect to network at all. With mine it seems the IMEI is there. Its just that the OS is unable to read it. Dont you u think using the Qualcomm process would be a little harsh?
Also since its able to connect to network, i think my ISP is able to read my IMEI. Could i call them and ask them to tell me my imei? So that i could compare it with what is written at the back of the g3?
EDIT: I just got off the phone and the ISP/Mobile Network agent said they are unable to see IMEIs from their end.(Not just mine but everyones). I dont know, maybe she just might not know how its done. I will still keep trying tho.

Restoring using Qualcomm software IS hard, overkill and VERY RISKY. At the moment since your provider doesn't care, I say ignore it. Also I have no idea what would happen if you tried to change an IMEI to one not meant for your device as I've not ever attempted such. You phone sounds like it has a bad IMEI, but that would only as you said blacklist it on TMO. The IMEI afaik is only used to track stolen phones and deadbeats on bills. So as the saying goes "If it ain't broke don't fix it". If I were you, I would question the person you got it from about the bill delinquency, but you don't really have to. Just seems fishy to me.

[Q] 3G/4G Network phone in Edge mode

Hi,I have this issue with my T-Mobile Galaxy S3 (SGHT999)
.It seems to be in the Edge network even though I'm in a 3g/4LTE service area. The phone is slow.I could use a solution and looking for suggestions on how to fix this 4G network phone.I have another Galaxy S3 (SPH-L710) with another carrier with no problems. Well one problem I'm not with that carrier any longer. This phone doesn't have a sim card slot like the T-Moble phone has. The other problem is the wifi reception. Its ok in the room with the router but you go say 30' away and communication is spotty. Other S3 phone I could be 100' away no problem. I thought all Galaxy S3's were the same. Thanx for any help.

What carrier are you using it with? Make sure you have correct apn settings. For the WiFi not sure, 100 foot seems a little extreme for no problems, unless they were different routers

Sorry to resurrect an old thread but Im facing this exact same problem right now. I have two SGH-T999s, both unlocked, and while 4G works perfectly on one, the other only works in GSM/EDGE mode and will find no signal when I switch to WCDMA only. Both phones in the same location, the exact same sim switched between both handsets, works fine on one and not on the other. I have already reset the phone multiple times, reflashed the stock firmware, replaced the stock firmware with CyanogenMod 11 as well as the 12.1 nightly, NOTHING makes a difference. It will stick to GSM and EDGE only and will just not connect in 3G/4G.
At this point, I am guessing this is a hardware problem. The same exact stock firmware has been flashed on both devices, so it cannot be a difference in version. The phone with the trouble has been dropped and has a shattered front glass. I wonder if something else might have been knocked loose when it fell. I opened it up and tried to reconnect the antenna, but noticed that only one end was using a connector, the other end appears to be soldered. I did not try to pull the motherboard out, nor touched the sim tray.
Does anybody have any suggestions on where to look next to troubleshoot this problem?

I am also having this same problem; I've tried everything, including the things on this thread: http://forum.cyanogenmod.org/topic/...ge-on-phone-and-not-34g-imeidata-issue-fixed/
If anyone has found a solution, that would be great...

Check to make sure the imei in About Device isn't blacklisted and that it matches the one under the battery.
If it does and you have Odin flashed the stock firmware and factory reset, it is most likely a hardware problem.
FYI, the antenna you see when you open it up is the wifi antenna, not the cellular one.

Hmm, I saw that there was an IMEI present, but never considered it could be different!!! You are right, the IMEI on the back of the phone does not match the one shown in About Device! How could this have happened? The person who used it before is not someone who fiddles with their phone... The best I can think of is that whoever unlocked the phone for them must have done this!
I did see numerous threads about missing IMEI, but didn't pay attention because mine was not MISSING it! Also noticed it is against xda site rules to even discuss that stuff. But since I inherited a phone that came like this, I guess the mods will forgive me for saying "let me google this"
EDIT: Oh yes, the IMEI on the back of the phone checks out.
Also, did not know the antenna was the wifi one! But since its IMEI related, I guess thats not an issue anymore

Fixed it!!!
UPDATE: As per DocHoliday77's advice, I'm deleting the links and explicit instructions. Suffice it to say all the information you need to do this is available on this site itself.
After @DocHoliday77 pointed out that the IMEI may be incorrect, I did some research and managed to restore my IMEI as well as get 4G back.
I was able to restore my device because I had the advantage of having a fully working device with me from which I could pull the EFS partition as well as get an NV dump. For those that do not have a second device, I do not know how they can get things working again. In anycase, all of the information I needed to accomplish this was found in three threads on this site. The only additional piece of information that T-Mobile users need is that to get your device into Diagnostic mode, the dialer code is *#0808#.
Wanam's Partitions Backup & Restore... does a much better job at backing up the correct partitions for EFS.
EFS Professional for everything else.
And before anybody asks, sorry I cannot provide you a copy of my EFS backups. Only becuase I am not knowledgable enough to know how much personal information is contained in that partition, but given that the IMEI is dependent on it, I hope you can understand why I cannot share mine. Perhaps DocHoliday77 will be able to suggest a way for others to get this sorted out.

That's great that you got it fixed! And kudos for figuring it out on your own!

Sent my unlocked Note 4 in to Samsung, PBA replaced, will it still be unlocked?

Hi Everyone,
As the title says, I sent my SM-N910A to get the crashing/restarting/hanging/lag/restarting issue fixed. I was using a partial wakelock app the last few months and it fixed most of the problems, but the phone kept on lagging more and more, so I decided to send it in while it was still under warranty.
I looked at the info provided on the RMA portal of Samsung's website, they said that " SOLUTION: Replaced Cosmetic - Replaced Component - Replaced PBA".
From my understanding, IMEI is the same, but what I'm worried now is that my phone is going to be re-locked to AT&T, which isn't fun as I don't even have an AT&T SIM card or account, so I don't know how I'd go about getting it unlocked.
Has anyone else sent their unlocked SM-N910A to Samsung and got it back locked to AT&T? If so, what did you do to resolve it?
Thanks

I'd Contact Samsung support first thing in the morning and ask. They are usually great to work with....

I have an att note 4.
Once the phone is unlocked, the phone remains unlocked it should NOT reset.
If you've rooted the phone (which there's no root for att note 4) that can be reset, bc rom they flash is usually not rooted.
This is my understanding, experiences will differ. Please do followup with your experience once you get your phone back.
Good luck.

I would, except for the fact they said that they've never heard of my issue, that updating the software/uninstalling apps will fix it, thought a wakelock was equal to rooting (even though you can't root the AT&T version), etc. Since this I've had little faith in them aside from the actual people doing the repairs at RSI...

I know the unlock wouldn't reset normally, but I'm assuming if you replace the PBA, that includes the baseband processor, which in turn would result in a different IMEI, which in turn would be re-locked to AT&T. I don't think you can replace the components and assign the same IMEI to the device.
I know this is a question for Samsung, but when you email "tech support" and they tell you that if the processor is bad, they'll just replace the processor (you know, the one that's soldered on the PBA) I start to get a little low in confidence...

An update for everyone who was curious:
I got my device back, several components were replaced, and the phone basically looks brand new, even though I had taken good care of it.
Now, the IMEI of my device is the same, which confuses me even more, especially when I powered it on with my non-AT&T SIM card installed and was prompted for the unlock code.
Thankfully, I was able to reach out to the person I bought it from (new & unlocked) on eBay, and he provided me with the code, and it worked flawlessly. The best part of all of this is I'm on Marshmallow now, and notice several improvements (and like it more aesthetically). The RMA was straightforward with RSI (Samsung's partner) and I've got a non-wakelocking device once again.

i sent my unlocked AT&T Note 4 in last month to replace the rear camera (focus problems)
under warranty and they broke the LCD while taking it apart so i got a new LCD too. it was still unlocked
when i got it back.
