[Q] sold tp2 uscc to verizon guy

Hi I sold an unlocked xpress rom tp2 to a guy who had verizon.. he said verizon would not activate it at the verizon place.. i thought it would work??

well **** he did ebay dispute and it took the money out of my paypal acct! talked to him on the phone and he is sending phone back tomorrow.. learned something today ;/

Of course the company isn't going to support a custom ROM. I would have sked for my money back too. You should have returned it to stock conditions before selling it.

custom rom wont affect activation, the fact that it was a uscc phone caused the problem, next time only say it will work on uscc unless it has a bad esn

Using a branded phone doesn't make a difference so long as you are going from GSM to GSM or CDMA to CDMA. Verizon and USC both are CDMA. Several people on these forums have done the same thing.
He said the other guy took his phone into a Verizon store. If they see you aren't running the stock ROM, they will refuse to activate it. I used to do the same thing when I worked for T-Mobile. We could take someone with an AT&T phone and port their number, but if we found out they used a custom ROM, then they would have to get a new device.
Custom ROMs are never, ever supported by carriers. I'm not saying that this is definitely the problem, but it is very likely.

You need to Learn a bit more on CDMA. Just cause a phone is unlocked won't mean it can be used on other carriers. Verizon has to add the esn to their database after Whiich he can have a Verizon line added to it. So it's not the same as gsm

Yeah guy took it to verizon and they actually tried working with him but no luck with activation over the phone..they didn't care that it was uscc supposedly... Thanks for the help.. To bad these a hole carriers won't do WHAT THEIR TOLD! AH HA.. Thanks for info

Same thing happened with boost. They could not activate it cuz it was not added to the database. I think only metro pcs would do it for a fee. Not releally sure

Verizon will NOT add a foreign esn to their database. They will only activate verizon phones.

yup, Verizon doesn't activate anyone else's phones. Only phones with ESN's they have in their own database and they won't add a phone to it just cause you want them to.

How can an "unlocked phone" not be "unlocked"?

I asked this question a few days ago & no one answered, so I will try a different way.
Verizon tells me that my phone that is "unlocked & rooted" with CyanogenMod 10.2.1 is not truly unlocked.
So how do you completely "unlock" a phone so that it will work on Verizon's CDMA network?
Is there a different way to unlock for CDMA?
Thanks.

If your running cyanogen mod your bootloader is unlocked. There's two different kinds of unlocked, one is sim unlocked which means it can run on almost any carrier and bootloader unlocked meaning you can flash custom roms
As far as CDMA not that I'm aware of

Thanks. I couldn't understand how a phone can be unlocked & rooted & still not be unlocked. The salesman at Verizon told me on the phone that whatever company originally sold the phone would have to unlock it. I forgot that this was a T-Mobile phone. I use T-mobile sim via Straight Talk. If this sim is removed then would the phone be able to work on Verizon network? Verzion is telling me this is a GSM phone & not CDMA & won't work unless unlocked by carrier. Which makes no sense if it isn't a cdma to begin with. I assume that all Verizon version of phones are made for them as CDMA only?
If this is so, then Verizon should not be advertising "bring your own device" as it won't work. It should be "bring your own Verizon phone".

Verizons idea of bring your own device really isn't what it should be. It should work on the vzw network but all phones should be sim unlocked by the carrier as a law was passed to do so, however verizon won't a lot of times sim unlock it like it should be until the contract is fulfilled.
And yes there bring your own device is irrelevant because most gsm phones won't work like they should on this crappy network because they are the only CDMA only network left.

Thanks ShapesBlue. I assumed it was not really bring any device to play as they state. My phone came from T-Mobile from the original buyer, so I don't know if T-Mobile would till unlock it or not since it isn't stock any longer. I have a friends that use Verizon & they get good service in our area. Mine is limited on T-Mobile, lot of dead spots especially where I work & slow data. I had a non digital CDMA phone that I used through Straight Talk & it used Verizon network & I got good phone service in places way off the beaten trail, so that is why I wanted to try Verizon again.
Where can I find a copy of the "unlock law". I searched for it but didn't find anything. I would like to print it out & take with me for proof.
Thanks.

At&t moving to TMobile

Good afternoon all. I am thinking of switching my phone from AT&T over to TMobile. When I do this, will I then be able to install custom roms on the phone? Thanks in advance for your help.

If it is the AT&T model, then no. Only the carrier will change but the bootloader will still be locked and be unable to be unlocked at the present time. Sorry!

Thanks so much for answering this. I was about to switch over. Now I know it wouldn't do me any good.

Only good that would come of it is Tmo would pay your AT&T phone off and you can get a tmo v10 and unlock it. Tmo has binge on for youtube I use a lot . But if traveling AT&T has far superior coverage period .

I think I'll hold off on switching for awhile. I ended up getting the Note 7 on Tmo for business, so I'll definitely take advantage of Binge On. Thanks for the info.

I actually switched from ATT to T-Mobile last year. My best friend is a VP at T-Mobile. I have to say the phone was bootloader un-locked 10 minutes after leaving the store. Literally just a debug option. I live in North Texas, and where T-Mobile works they can't be beat. I was getting crazy speeds, 50+mbps. But there were lots of spots where it did not work. To the point I couldn't place or receive a call. Places that ATT and Verizon work. I also told them at the time of switching to them I needed two Cell Spots. I knew their service would not work at my home or at our lake home. They agreed, and for the next 5-6 months I played this game where they would only allow one to be activated at a time. So after about six months of it I bought out my contracts and came back to ATT. Yes I have a T-Mobile V10 unlocked, rooted, custom rom working on ATT. I get decent speeds but not what I get on the ATT Variant of the phone. I wish t-mobile was more complete on their coverage, while they may have coverage in more cities I don't think it's as complete coverage as ATT or Verizon. I also did not find that their plan was all that much cheaper than the ATT plan. Sorry for the long rant, just my two cents.

Is it possible to flash H960 international version .kdz file on H900 at&t version? If anyone does it, what are the issues caused? I was planning to do the same but I am new to LG.
Let me know if its possible and what are it's implications.

ATT GS7 unlock issue

Hey all,
I recently bought an ATT branded Gs7 from the online Samsung store, I have tmobile but I missed out on the tmobile sale of a few weeks ago. I haven't turned on the phone yet. I tried to complete the ATT online device unlock request, but I got the following message: "We're unable to approve your request because the IMEI number provided doesn't match a device that's currently on the AT&T network." I called ATT and they said they were unable to unlock it because it was never on their network... So does anyone know what to do?
- I'd rather not pay $20 to unlock the phone
- The phone did come with an ATT sim card though I have no account. Should I insert the sim card and turn it on? It won't make a difference later when I unlock it and flash the tmobile ROM, right?

Im in the same boat as you. I read somewhere inserting the at&t sim isn't a good idea. Don't remember where i read that. This worries me because i haven't received phone yet and also need to unlock. If i come up with anything I'll reply

Thanks....Anyone, anything?

I bought my s7 from cricket, but then I flashed it with the 930u firmware so it's now unlocked and will work any network, any sim card

We bought the 930a from ATT (and flashed it to 930u). I couldn't get it to work on anything besides ATT and cricket. I spent hours on the phone with ATT, eventually they told me they could only unlock the phone if I kept it on ATT for 3 months..... Even though I bought the phone at full retail.
We discovered all this after stepping off a plane in a foreign country. Ended up paying 20 or 30 dollars for an unlock code because we need it fixed NOW. It worked, and I hated to pay it, but ATT have me no other option.

930u doesn't have nougat yet. Supposedly next month is what I've heard apparently the 930u is only quarterly updates.

AT&T or T-Mobile for unlocked S8+ ?

The backstory.... Preordered an ATT Note 7 and had many headaches with delivery / billing. I am now living with my old Note3 using Goggle Voice/Hangouts because of my weak signal (all carriers) at home. I'm using a pre-paid Straight Talk plan when away from home.
I've been waiting patiently for the S8+ and now need to decide between AT&T and T-Mobile for a GSM phone. I plan on paying full cash price and having it unlocked to use a 3rd part prepaid plan (Straight Talk or ?).
I considered a factory unlocked phone (Best Buy, May 9th??) but I am told that those will also have a locked bootloader. Up until the Note 7 I always ran rooted with custom ROMS. I became a big fan of Samsung Pay which I think also means a locked bootloader with no root is needed. Of coarse, bloatware sucks. I had good luck with Package Disabler Pro on my Note 7. I will be using my Google number, if only for forwarding to another number. WiFi calling is a must one way or another.
My Note 7 from ATT let me run Mobile Hotspot at the same time WiFi was enabled. This made it easy for giving my Android head unit in my car Internet access. The T-mobile version at the time needed to be turned on and off.
I'm leaning toward T-mobile only because of my bad blood with ATT. ATT coverage is marginally better in my area.

Either and flash the OS on it with ODIN. It is the same hardware so it doesnt matter.

Yes and also if the T-Mobile version is going to have an unlocked bootloader, flashing T-Mobile firmware should allow you to unlock it through the OS.
But it's highly unlikely it will have an unlocked bootloader, although T-Mobile have supported it, I don't think it's happening.

No unlocked bootloaders on u.s.a. Carriers....

I get that if you buy a carrier phone and then unlock it. But what about the factory unlocked phones sold in the US?
I've heard that the bootloader on those phones is also locked, but not from a real good source of info. I've also heard international versions do not have a locked bootloader and do not support Samsung Pay. They also do not support CDMA (which doesn't bother me at all).

I'm in a similar situation and my first concern is what bands both phones support. Online it seems AT&T covers both GSM providers perfectly. The info on T-Mobile and its bands is extremely lacking. My second concern is the process of unlocking either fully paid off phone for use on the other. I think I can have TMobile unlock it for me but I'm not sure how it works with AT&T. The easiest solution is the unlocked version but thats not even got a release date set in writing anywhere.

As long you are flashing official firmware from Samsung nothing will break. Knox will not be tripped and Samsung Pay will work.

It is my understanding that all US (Snapdragon) phones cover all bands, including CDMA. That means you could even take an unlocked AT&T phone to Verizon. I'm not used to that! It even has LTE-U which TMo is supposed to be soon supporting.
I am an ex AT&T customer. They unlocked my Note 7, and again with the replacement, without issue. I seem to remember there was a wait period at first. 7 or 14 days?
The thing I'm considering is also the VR incentives for pre-ordering. I can tell you AT&T messed up my Note 7 pre-order. They shipped it on the release day by a slow method. I ended up going to a store and buying one outright and returning the unopened one once it arrived. That caused a billing nightmare that I had to call them every months until I finally turned it in and closed my account.

Can you recall where you read the carrier versions support all the bands just like the unlocked versions? All the info I found from the carriers shows different bands on each model.

You're missing what I'm saying... There will be no unlocked bootloaders on any Samsung S8 phones for the USA. You cannot get one from carrier or factory.
I think you may be mixing up Bootloader unlock and Sim unlock....

I do remember that it was a story about FCC approval of the factory unlocked (SIM) phone. Keep that in mind that it may be the unbranded, factory unlocked phone only, but the article did say they were all the same. The locked carrier phones may not be so flexible.
Other things I've found.. Best Buy SIM unlocked does not get the incentives. Best Buy, and their cheaper price, does not seem to offer a T-Mo phone.
The VR incentive is attractive to me, but is not a must have. At this moment, until I can find out for sure if Samsung Pay will work on an international version, I am leaning towards a T-Mo pre-order. But that is me and my preferences YMMV. I have a major dislike for AT&T.
Looking for where I read it. In the mean time this may be interesting to you.

You're correct that it seems T-mo info is evasive.

Hello,
I would like to know, if it posible to buy the Galaxy S8 from the samsung web page (att version), then unlock it and after that flash the unlocked rom flashing it with odin.
Can someone help me?
thanks.

Just ordered the 955F from Clove...
I'm hoping that missing bands won't hurt my AT&T usage much. Or any prepaid sims I may throw in there.
Will see if the 955U info comes out before my phone, and will decide if I want to cancel.
