I can't find any information on flashing samsung vibrant to cricket. I don't care about a full flash, voice and text is fine for my purposes. I don't care about data or android market or any of that.
I have seriously been NON STOP looking for last 2 days with no luck. I checked the cricket forums and I searched the forums here without any luck. I am an amateur I am not going to lie.
But I have a very good general background in technology and, I have already rooted the phone. I was trying to follow a guide I found but honestly I am not 100% sure that even does what I want it to. QPST samsung vibrant but when I do it I cannot simultaneously connect both the phone and run the software. If software is running first my computer won't recognize the phone as a modem and if the phone is connected first the software freezes and I can't even close it with task manager, I have to reboot comp.
Any help at all would be appreciated. I don't even know if this is the right forum for this question and I am sorry if I put it in the wrong place but this is vexing me.
Does cricket even use sim cards? If they are not a GSM carrier, it would make it impossible to use the vibrant on their network/service
Sent from my GT-I9000 using XDA App
Cricket is cdma (sprint, Verizon, us cellular type radio, meaning no sim card) and the vibrant is gsm (meaning it uses a sim card).
The vibrant cannot and will not work with cricket.

Well question solved. Definately not the answer I wanted but that can't be helped.
Are there any nationwide carriers that use GSM available similar in price to cricket? I will be looking into this right after posting this question but I figure I might as well see if anyone knows any decent ones they can recommend. Basically, looking for cheapest possible with nationwide coverage.
I just need talk and text. Preferably no activation fee and no cost for sim but I know I am being overly optimistic with that lol. I also know that this forum isn't the place for that so any help is appreciated but I understand if no one has an idea.

there is the one that wal-mart sells that you could look into
T-mobile note users ....
I'm posting this thread as a request for information today.....let me explain.
Within the past few weeks, many members have reported sim card errors on their tmo devices after root and flash of custom roms.
I personally know about 5 devices within the week that have suffered this failure.....3 of which, have been recovered by downgrading to Gingerbread .....
I'm sure there are many more sim issues we haven't heard about, as they likely haven't posted.
My intent here, is to have as many tmo users as possible, post your flash success or failure, in an attempt to prevent more sim failure issues.
Although I'm an ATT note user, I'm willing to help monitor and collect data here, so future users won't suffer the same fate.
2 of these failed devices were sent for repair, even though they were only days old, and worked perfectly prior to root and flash.
So please, if you are using the T-mobile network........please post your history and results.
Together we will likely find the cause .
And perhaps generate enough attention to the issues, that a fix can be found...
I am not attempting to cause panic, but I feel we need to fix the problem now, before we have dozens of affected units, rather than just a few.
Many thanks in advance ....g

I would mention that many t-mobile subscribers cannot get good data and voice while using the at&t version of the note. With the choice of an at&t and a t-mobile model, you should get the t-mobile model -- you will be happier in the long run.
Happy T-mobile user

I bought an AT&T note off craigslist about a month ago. It was unlocked, before I handed over the cash I put my T-mobile sim in and called a friend he said it sounded great so I bought it. I did a couple of speed tests with it and usually get between 3 and 6 mbps down and a lot slower up. I've had no problems, everything works great including GPS. It's running ICS 4.04 stock AT&T ROM and the baseband is unknown. I don't know who unlocked and set it up but they did a great job as far as I'm concerned. YMMV
off-topic, deleted.
It's all good ranger ....
Any and all info on the T-Mobile network while using the ATT note is welcome ....even the success stories.
I did request both in the OP, as I feel that we need both sides of the user responses to nail this thing down.
I do appreciate your response, and ask you for any assistance you can provide here.
This problem is so odd .....as it's not a brick ....but yet it is ....g
I sold my note to a TMo user...called them today(two days after) and they said it was working amazing....it was rooted and unlocked by an amazingly awesome person though(haha jkjk). The guy never rooted before and said the speed tests were rocking his gfs GS3 in TMo and the clarity of the call was great as well....ait could be a root issue or ROM issue though...
As far as unlocking if the pgones unlocked any way except for calling ATT customer care there is always that risk...plus a three minute phone call and giving someone your imei shouldnt be too much hassle .. So theres that dudes exoeruence from someone that knows what they are doing(kind of)...
The rom I left him on was AOCP CP3 by the collective jsyk

Kflan....
noting the unlock method here.....
I believe you are right.....We have many service unlock options, but only one that is safe....and thats the carrier method...
could this be as simple as users not unlocking the sim prior to root and flash ??? or an improper unlock ???
I'm hoping we can get some users in here to clarify that possibility for us.
Many thanks for bringing that up....g
Thank you Rob....
I appreciate the reply, and I'm glad your device is working as it should...

Users on the T-Mobile network, are losing the ability too see or access the sim card, after rooting and flashing the device with a custom rom.
Generally they are flashing ICS, but we also have some users reporting sim loss while using GB roms as well.
We know a few things that are leading to a possible cause.
The first is the carrier offset (my term for t-mobile users with an ATT device )
The second is the need for carrier unlock for the device to be used at all with t-mobile.
The third is the inability to restore "any " sim activity after the failure....(although a few users have been successful after a complete unroot and downgrade to GB .
Although I haven't yet found a pattern in this ....I have reason to believe we are seeing a carrier related lockout of some kind, as the sim functions fine in other devices, and the device functions normally minus it's ability to detect the sim or any network.
Perhaps a good next step, would be to re-lock the device to the carrier again, after a complete stock restore of the device.
I wish that we had an affected device to try this with, but unfortunately, the affected users are returning the device for repair or replacement.
Not all users will, as they need a working device immediately, and are trying desperately to restore functionality.
That being said, I'm hoping this thread will draw an affected user here, so we can explore more aggressive, and hopefully effective solutions.
I can't ask anyone to risk a device beyond their willingness to try, and with some proactive thoughts from our fantastic user base, we will crack this problem open, and create a fix.
We all know the risks involved in flashing firmware images, but since we are now crossing not only the root/flash barrier, we are adding the carrier change into the mix. And that brings it's own unique set of challenges to the table.
I sincerely appreciate any and all help, in my search to help our note users succeed in fixing the ghost in this machine ....g
I know this is a noob question but I've been reading all these t-mo service/I717 threads cuz I'm thinking of doing this. Does rooting the phone unlock it? I'm on the liquid jb rom.
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
I would like to echo what rangercaptain said earlier in the thread, regarding the fact that the SGH-I717 was never designed to run on the T-Mobile network.
And although we have virtually identical hardware and operational features, clearly something is different enough to cause this issue.
And I "do not " believe it is user error.
In the meantime, I would advise any user thinking about converting the ATT note to use on the T-Mobile network, to think very hard before attempting to do so......at least, until a verified and working solution can be found.
Ultimately, we need a bone stock ATT note, and a t-mobile user brave enough to try the process repeatedly, until the cause is identified, by eliminating one process at a time ...g

Rooting a device simply gives it's user the administrator rights needed to access the protected system and data sections of the device, that are normally reserved to the factory, carrier, and programming engineers of the software.
It does nothing to unlock you from your carrier.
That is done by contacting the carrier, and requesting that service.
It is also possible to be unlocked by a third party, but clearly their are risks involved in doing so while using the ATT note on the t-mobile network.
We are working very hard to correct the current "no sim card present" issue ...g

I have been running the AT&T i717 note on the T-Mo network since Tomin figured out how to get the 4g working, many months ago. I have not had problems with voice quality or sim card issues. I have run the Saurom GB roms, Goldie's Only1, many ICS roms, and now am on the stock T-Mo rom with the Blaze ICS modem.Tried all the modems, and Blaze works best for me. YMMV. I got a new sim from T-Mo to enable wifi calling. My data averages 3-5 megs, upload 1-1.8 megs, but at work I regularly hit 14 meg download. But like everyone, the speed is erratic, but functional for everything I do, including streaming netflix. My speeds were faster and more consistant with the GB roms, but the ICS speeds are plenty fast. I unlocked my phone with cellunlocker.com I think was the service. Nothing but a success story with my AT&T note on T-Mobile. And I get to keep my unlimited, unthrottled $5.99/month grandfathered data plan with 4g (if I used a "known" to T-Mo 4g phone I would have to upgrade. The AT&T note is "unknown" to T-Mo, If I got the T-Mo note it would trigger new data charges). For me, this is the point of the whole excersize. I have been lucky, and the Phoenix area has good coverage for me as far as T-Mo. This has been my experience.

Mine was rooted then I unlocked it so maybe try rooting first unlocking second?

So I looked around the threads on both Verizon, and Sprints side of the fences for an answer to this question and couldn't find any thing.
I have a Verizon Galaxy S3, and my contract with Verizon recently came to a close. I want to switch to sprint due to pricing and other options, but I don't have the money to drop on a new phone at the time, so I have been looking into unlocking the phone to work with Sprint, however I haven't much of luck...
That's when I came to XDA. While I was looking around the forum, I got to thinking.
Is there any possible way that I could take the Sprint version of the Samsung Galaxy S3's ROM, and load it onto my Verizon Galaxy? And has anyone tried this yet?
It's essentially the same hardware, right? To the best of my understanding, the only difference in the phones would be software related according to the carrier.
I am really struggling with this one, and I have witnessed the vast knowledge and great work by this forum before, so I am hoping I'll be able to find the help I need.

Verizon and Sprint do use the same cdma networks but will not activate each others devices on their network so the answer is no I do not think this is going to be possible for you.

Well I did talk to Sprint, and Sprint said they would be willing to activate an unlocked Galaxy. It's just the unlocking process that I am unsure of.
I read a few threads and am confused, so I thought I would just ask. I have a few 4G LTE devices for Verizon and am ready to switch to AT&T. Let's just say that Verizon and I had an argument and it is time to switch. Plus I would be saving over $50 to switch to AT&T with a month to month with a BYOP plan.
I visited the AT&T store today and had them insert a SIM into my S4. I get the error "This SIM card is from an unknown source" in the banner. I get a signal strength and a H for where the data symbol 4GLTE is. Then it drops the signal and refuses to have a data connection. At this time the APN settings were NOT adjusted. This was a straight out of the box S4 rooted on NC5 with Android version 4.4.2. After messing with the S4 for awhile he moved to the S3 and entered the proper APN settings. It pulled data, but only at EDGE speeds or 1X. Also, my last device, a Samsung Galaxy Tab 2, has no way of editing the APN settings. It is NOT rooted and is still on stock firmware.
My questions are these:
1. Can this be done?
2. What do I need to do to the phone(s)/tablet to make it work?
3. Will I be able to get 4G speeds?
I do not want to purchase phones with AT&T today because I just don't have the money. I already have these devices, I just want to swap them over. I am comfortable with flashing using ODIN and even so far as using safe-strap. I have flashed some custom roms, but my phone is a daily grind phone and I really want something that works 90% of the time.
Thanks in advance for any help!

That thread just asks if the SIM card would work and if they would need to flash a GSM ROM to their S4. That thread does not answer the questions I asked. I just gave my insight after a visit with the AT&T store. Store techs tend to not know as much as the XDA community. That is why I asked here. So no, it is not a redundant thread. I appreciate your answer, but it isn't what I am looking for. Not a straight up yes or no, this or that.
As for the GSM locks I discussed, it was from an experience I had with a Motorola Droid 2 and using it on a local GSM provider in the USA. So yes, that was pre LTE.

My point, which you apparently missed, is that there is no reason for starting up yet another thread to ask questions that have already been answered. That''s why I said that this is redundant.
OK, let me answer your questions.
1. Can this be done?
Yes, you can install an AT&T SIM, set up the APN, and it will work. What bands you get and what bandwidth you get depends on what bands AT&T are using in your area. You won't likely be able to get LTE speed; most likely just Edge. You can't fix that, as it's a limitation of the phone's radio hardware. Again, some people have made claims that you can flash the AT&T GS4 modem on a Verizon phone and change that, but that's pretty risky as it will likely brick your phone.
2. What do I need to do to the phone(s)/tablet to make it work?
It works, for some level of "work". If you're stock,some people have reported that the firmware requires CDMA for some functions, like SMS. I haven't verified that. I was able to send SMS with my phone and a UK SIM which uses the AT&T network.
3. Will I be able to get 4G speeds?
Not likely. For example, see here http://phandroid.com/2012/12/10/nexus-4-att-lte/ - the common band, LTE Band 4, has limited AT&T coverage.
I haven't gone over the specs of the two phones lately to match them up, so that may be worth looking at again.

Thank you for your answer. I decided to trade the phones into AT&T and get a credit towards a Samsung S4 and a Asus Padphone X. After I read a few more posts over the internet and a few more hours figuring out how LTE works I came across the answer. I did miss what you meant and I apologize. Again, thank you for your answer.
