Phone keeps connecting to Verizon tower?? - Hardware Hacking General

I bought a note 2 running on us cellular but whenever you call out or do anything calling related verizons automated voice comes on. I bought the phone for 50 bucks and its 9/10 condition so i figured if i cant get it to work the phone its self works perfectly. But now that i invested around 8 or 9 hours trying to figure out why i cant do anything and why verizon comes on a US cellular phone. But If anyone could help me out it would be great. The phone is indeed rooted running 4.4.2 and i have access to supersu and i have some CWM 6.0 version or something. Any ideas? Even if i can just get it back on the us cellular tower would be fine but if i could just unlock the device so it DOES work on verizon that would be even better.

How to reflash a Boost Mobile phone?

My sister bought an S4 off of eBay that was set for Boost Mobile and has had issues with it since she got it. She tells me that when she boots it up that a bunch of error messages pop up but once she closes them she can use the phone for calls and text as well as the internet but only on WiFi. She gets no mobile data and no GPS but does have a SIM card in it, however Boost is not able to activate the card.
She tells me that the phone is a former Sprint phone, and has contacted Boost about her issues but there has been no resolution. They have tried sending firmware to her phone but it has not helped. I do not have physical access to the phone as she is in Florida and I am in North Carolina. I have flashed my AT&T S4 before with no issues and want to try to help her. She however knows nothing about flashing phones but is willing to try it.
What I am trying to find out for her is what she could do to get her phone working the way it should. Would she have to flash it back to a Sprint phone and then to Boost again? What software and firmware would she need to do this? Would she lose her phone number or be able to keep it? I know nothing about doing this but can figure things out pretty well and can follow directions to do the job, and would also have to walk her through doing this herself. This is her only phone and she can't afford to get a different one right now so having this one working is important for her.
Any help with this would be greatly appreciated!

If the phone was originally on Sprint and someone flashed it to Boost Mobile, I can see why she is having problems. I would advise that the phone be returned and obtain other one that hasn't been modified. Boost Mobile will RESKU the Sprint Galaxy S4, S4 Triband and S4 Mini that haven't been modified at no charge and everything will work.
The full list of eligible Sprint devices are listed on the link below.

Questions on Unlocked htc 10 being used on verizon ( not full verizon conversion )

Does anyone know what this letter C like deal is between my wifi symbol and my call signal ? I was going to ask dottat big D but it seems we have lost him to the forum. He will be missed he was always a good contributing member and a good friend to many of us including myself. He will not easily be replaced and he will be missed. Best of luck to you D a lot of us appreciated everything you did for us.
Now on what I have going on, mine is an unlocked htc 10 s-off unlocked, verizon picks it up as a verizon htc 10 for reasons we are not supposed to discuss on here, so what was done is flashed the verizon htc 10 radio and such as Dottat has on his thread, but what I think is going on is mine is picking the verizon signal up as roaming which it is not, so my problem is in the phone itself and not in my verizon service. The reason why I have it set up to be picked up as a verizon 10 is because I run it on total wireless prepaid which is $35 a month unl talk & text with 5 gigs of verizon data throttled to 5 mbps down and two up. If it was on a post paid account then I could activate the sim in another phone and put in this unlocked 10 and it would work fine registered as an unlocked 10, but for total wireless if you activate the sim in another phone and put it in the unlocked 10 you will only get 3g data I think its this way for all verizon mvno the only exception would be verizon prepaid.
So here is what I have tried I"am running viper10 2.2.0 the first time in viper set up while flashing I selected the phone as unlocked 10 which is where I"am back to because I tried flashing again and selecting the phone as verizon 10 and it was working great problem fixed until I find out camera wont work it turns on then right back off so I tried uninstalling the htc 10 camera app then clear cashe and reboot and re install it from the play store and same deal open the camera app and it closes immediately, then flashed viper again going back to selecting phone as unlocked 10 during rom flash, and camera works great again. I really do not want to convert to a verizon 10 as I like my updates from htc directly and not from douche bag verizon lol. Anyone know this issue ? I do not need to convert to verizon 10 as prepaid does not use Volte so converting is worthless and of no benefit. I dont know if the issue is firmware related but wouldnt you think the unlocked 10 and verizon 10 would use the same software for the camera ? It makes no sense. I guess for the time being I wont have a camera and if I cant find a camera fix I will wait it out for the new nexus 5.5 inch screen phone expected to be due out in a month or two. Anyone have any clue on a camera fix ? Because as unlocked 10 flashed viper10 it works great except the camera wont work at all ?
Here is a screenshot showing the C
I forgot to mention not only is my htc 10 trying to roam, it does not want to send texts they fail sending and that is even trying using verizon messages. And I tried flashing the verizon radio again each time after flashing viper10 and switching from unlocked 10 to verizon 10, and then back to unlocked 10 again to confirm camera was working right again which it was now I will have to flash viper10 again and once again set it up in flash as a verizon 10, have no choice, either my total wireless verizon mvno service works and camera does not or camera working and no service yeah thats a no brainer lol. So there is where I"am and no Dotat to save me this time lol
you cant use the unlocked option on viper if your going to use it on Verizon. the Verizon option in aroma flashes the necessary files to make it work properly on their network, like system apps, libs, apn info, framework files, etc.....
the camera breaks due to mismatched firmware on your phone. you need Verizon radio and firmware for it to work properly. flash the latest Verizon RUU and radio if needed and then reflash viper with the Verizon options. if your using it for Verizon the unlocked firmware and options no longer apply to you and are now on verizons time when it comes to updates.

Yeah I will pass on that I guess I can do without camera as I do not want to convert to a verizon version. I like my updates quick and clean from Htc and not from slow verizon who takes months so they can try to figure out extra bloat to add or any other ways they can try to lock your phone down more.
With viper10 2.2.0 set up as a verizon 10 then flashing the verizon radio everything works perfect except no camera so no camera is better to me than putting any nasty verizon software on my phone I dont even want their firmware nothing verizon that I absolutely do not have to have like my unlocked motorola nexus 6 is I get nothing from verizon but the call signal and their LTE data just as it should be.
I just flashed the 1.19.605..9_s_on RUU that Dottat provided for Verizon onto my Sprint HTC 10. Everything works great, except for one thing: the camera launches a black, flashing screen in any camera app. I'm guessing this is due to some mismatch of firmware on the device?

Can anyone shed some light on this? I read on this thread here that people are experiencing this, but it isn't clear why, and what possible solutions might be...

Can't get PH1 to work on US CELLULAR!

I brought it in to US CELLULAR to get it turned on and the agent could not get it to work. He spent over a hour with tech support on the phone trying but with no luck! Essential's web site clearly states it will work on ALL major networks. I also went to ( Will my phone work) web site and it said it would work. Am I missing something and is there anyone that can help? I would love not to have to return this to BestBuy.
Do you have any updates on this issue? I’d like to get the essential phone, but us cellular is the only carrier that works in my area...
Thanks!
US Cellular being a CDMA carrier, all they have to do is add the MEID to their database. Is that what they're having an issue with?
original poster still hasnt updated. I'd really like to have this phone, but unfortunately i have to stay with US Cellular in my area
My apologies I thought I had. I returned it to Best Buy. Agent at USCELLULAR said they did not have the correct codes\ frequency or something for this phone yet but USCELLULAR would receive them sometime in the future. I too would've love to had this phone! I had to settle with a LG V30+ which is not bad I must say.
success! and failure
I had successfully used the essential ph1 on u.s. cellular for a month. By telling the associate it was a Google Nexus 6p they entered that sap ID (the code on each phone in the UScell database mentioned above) and everything worked perfectly. Yesterday I spent an hour on the phone with uscell tech support after my phone had quit working on their network. They have updated their database again something in that update is not allowing the ph1 to be recognized as a nexus6p anymore. I will need to find another work around or go to a different carrier unless uscell gets with the times soon
Which is yours' IMEI started with, 3 or 9?
I have the same issue. Mine worked on US Cellular perfectly until a few days after April 5 update.
Mine starts with a 3

Note 4 no longer supported by T-Mobile No Network

My husband and I both have a stock N910T. When we woke up yesterday neither phone would get signal, and not even make wifi call. Went to TMo shop today they told me that they were no longer sending signal to Note 4's (Thanks for the heads up TMo). We really like these phones and I wonder if I could root them and flash a stable ROM and get service on them again. When I pull the sim it shows 5 bars, put the sim back and X. I have rooted many phones, but not since I got this one 6 years ago, so I'm sure I'm a bit rusty.
Any advice highly appreciated. TIA
I'm in the same boat with the note edge. It stopped working friday night for me. Put the sim in a stock note 4 and same thing, so I thought my sim card died. Went to the tmobile store on saturday and they said 2 people had came in with the same issue and they had note 4s.
What I don't understand is how they can just stop supporting a phone. I thought that if it accepts the sim card and has the proper bands it'll work. I mean for ****s sake my car takes a tmobile sim for a hotspot and traffic updates.
same exact. i just factory reset and updated stock to see if it would fix but it wont. Any solutions here??
Try to:
a. flash a custom TWRP (recovery) with Odin
IMPORTANT - after you flash TWRP PLEASE TAKE A FULL BACK-UP!
b. flash a custom ROM with root
c. why root? because you can change the build.prop file and "pretend" to be another phone (newer more likely) so that the lovely t-mobile can still allow your phone to connect to the network.
This way you have zero costs, you keep your note 4.
Unless it's too complicated or the procrastination level is TDH (too damn high)
Or you have the cash and buy something new(er).
There's info on this forum about all these steps.
Before you do anything - go and read, search on this forums and on youtube. There are a LOT of tutorials.
Please be careful and READ. Get educated about custom recovery/ROM's.
You will get good knowledge and your satisfaction on make things work will be enormous.
You will be responsible on your actions with the phone.
Good luck.
mine is already rooted with a custom rom. which parameters do you recommend changing in build.prop?
my audi is older than the note 4 and data works fine and calls work on a motorola L6 from 2005, so I doubt it's the age.
someone on reddit came up with a temporary solution until they fix this. you'll lose 4g/LTE tho
To set to 3G/2G turn on airplane mode and enter *#2263#* on the phone dialer. Then select GSM/WCDMA Auto. After that turn airplane mode off.
Hey all - same issue here - Note 4 stopped working Friday morning. I tried everything on my end (factory reset, ROM flash, SIM swap, etc). I even tore the phone down and checked the connections. I ordered a replacement SIM / SD card tray reader thinking that was the issue. Now I hear others having the same issue. I live in Colorado FWIW. Calling into T-Mobile now to see if I can get some info here.
---------- Post added at 02:50 PM ---------- Previous post was at 02:31 PM ----------
After speaking on the phone with a tech support person, T-Mobile reported that they were aware of an issue with Note 4 users not being able to access the network. They said that they "were in contact with Samsung and were actively working on an issue" and reassured me that they would have a solution for customers soon. I sure hope so because I do not want to give up my Note 4!
Note 4 user here too. This sucks. I did the workaround on the dialer posted in one of the above posts, and now it connects. Says 4G at the top, but probably only 3G. That's fine for me in the meantime, but not acceptable in the long run. I just spent 2 days wiping the phone, unrooting, etc only to find this now! Got lots of work to do to get it back to my rooted state. Thankfully I have the backups to do it, just have to find the time now. Thanks T-Mobile!!
Has anyone heard any more on this issue?
Just had the same issue. Called T-mobile support and they had no idea of a widespread issue, said it was likely HW failure. I got a new SIM and that didn't help. Called local cellphone repair shop and they indicated they'd had several calls about this issue and fixed at least one so far by replacing the card reader. I applied the workaround above and got the phone working again so I don't understand why a new card reader is going to fix this.
Note 4 seems like it's back working on T-Mobile as of last night.
HI I purchased galaxy note 4 3 years ago in the first time I put him on i has that problem yet
But I live in curacao in the Caribbean and I think that the mother board was not good.
Then I has flight to medellin Colombia with the phone he began working I was glad but when I arrived to curacao from medellin the same problem
Sometimes he is working sometime not
I have the same problem T-mobile N910T

Thanks for the update! I reversed the workaround I applied earlier and mine is back to 4G LTE now.
Any update on this issue?
The N915-T is spotty and I'm trying to figure out why. It was officially kicked off the network by T-Mobile, but it still works. It connects to most towers but not to a particular one. Whenever I'm on that block the network can not be found. If I walk two blocks away it would connect to another tower and I can make calls. If I walk back toward the 'faulty' tower while on the call, the quality would degrade, the call drops and the phone would lose signal.
This would NOT happen with other phones - not even an older Galaxy S2.
This is likely a different issue altogether, as the phone actually connects and works elsewhere. I'm just hoping someone has an idea.

AT&T forcing me to abandon my Galaxy S8!

Hello,
I am new to this site, and have a burning question I am trying to find an answer for.
So AT&T has been my carrier since about 2014. In July of 2019, I purchased an unlocked S8 from Amazon for about $350 Description says it is: Samsung Galaxy S8 64GB Factory Unlocked Smartphone - US Version (Midnight Black) - US Warranty - [SM-G950UZKAXAA]. In the settings, the model number is listed as: SM-G950U1.
Recently, I received a message from AT&T saying that they are shutting down their 3G network in February of 2022, and that my phone will no longer work on their network. I went into one of their stores and showed them that my phone operates on LTE, but I was told that is for data only and voice operates on 3G. I could not remember the VoLTE name at the time, but mentioned that my phone had the capability to operate on LTE. They refused to go thru settings with me, and told me that my phone will stop working in February. Period. End of story. Also, I was told the same thing that the message states, that they are sending me a new phone and will be deactivating my phone after 30 days.
Now some of my friends are laughing at me saying, "Dang free phones!" But I do not want a 5G phone (which is obviously what they are sending). I have my reasons and this is not what I wish to discuss here.
The issue is... I love my telephone!! It does exactly what I want, and I don't need anything new. Not to mention that I paid for it entirely, with no subsidy from AT&T. I specifically bought it unlocked with intentions of avoiding contracts and having the ability to switch carriers if I so choose.
I am pretty sure that I saw VoLTE mentioned in my settings a while back. But now a search on my phone finds nothing. I assume a firmware update hid this info from me.
So... what gives? Does anybody here know if this particular device can make/receive voice calls using VoLTE - on AT&T (or any other carriers) - simply by changing settings in the phone? Do I have any options to make my phone continue to operate as intended? With any carrier?
Sorry for the long post. Any advice would be greatly appreciated.
Sincerely,
Steve

Please let me know if this works. I thought about doing the same thing, but have not gotten around to trying it. In theory, it sounds like a solid plan. But I have a couple of concerns.
During a recent phone call, AT&T told me their system has flagged my IMEI and that my phone will stop working very soon. So, if the system flagged an IMEI as an unsupported device, will it even matter which firmware is installed? Or will their system just deactivate the phone at some point?
Second, if you install the 950U firmware in place of the 950U1, will the device become carrier locked at this point? That would really suck if it did.
BTW, I was able to lock preferred network to “LTE only” by dialing *#*#4636#*#* and entering Device information screen. Unfortunately, my phone would not complete a call when using LTE only setting. VoLTE provisioned toggle is greyed out, along with others. Seems to me that if a guy could self provision VoLTE, this would solve the issue.
I called AT&T tech support and spent 45 minutes trying to get them to provision VoLTE, but they could not, or would not do it. At first, they kept telling me that my phone is a 3G phone. I argued that I could change the radio to “LTE only” and that my sim card status showed LTE for “mobile voice network type”, which proves that the phone is indeed LTE capable for voice calls - but that it will not complete a call because it is not provisioned to do so. Eventually they told me that their system would not allow them to provision VoLTE for me, since it is flagged as an unsupported device. Which leads back to the first part of this post.
I also found some stuff on reddit about putting the phone into “engineering mode” and something about a Samsung tool that unlocks additional dialer codes. Have not tried this, tho.
At this point, I am just completely fed up with AT&T for this whole S8 situation, as well as other unrelated issues. I will most likely switch carriers for principle’s sake, even though I know other carriers play similar games.
Anyway, I am interested in whether or not you find a solution and would very much like to hear about it. Thank you for the response!!

Hi, I'm Newbie around here. I'd like to share my experience with ATT and my beloved S8+ this past few months:
Much like you and many others I started receiving texts from ATT by mid 2021 saying my phone would not work after Feb '22. Yes, every time they suspended my line I wasted 30~ 40 mins on the phone, listening how they would insist my S8+ was a 3G phone. It didn't matter that I offered to send them screenshots of my device showing the "VoLTE option" and "4G LTE" while both in the USA and Mexico. Thing is, they only based their saying on a st....id whitelist and all the reps are just talking heads.
I use an S8+ international version which is NOT on the dreaded list. and I am on the 300/year prepaid plan which allows roaming between Mexico and USA with no 50/50 usage limit.
I bought this phone on amazon for 350-ish bucks a couple of years ago and I love it!
I have to cross the Mexico/USA border very frequently and I need two separate numbers one on each country for business reasons so dual sim is a must. On the other hand, I receive lots and lots of phone calls while driving, this made me crave for android 8.1 when call recording was allowed by google, not the case anymore. None of these 2 features are available on the S8/S9 US based phones. I do not need 5G, I do not use social media nor watch videos on my phone but do get to use Pandora, Spotify, MLB radio and so on......... Enter SM-G955F/DS. I was able to change Samsung's CSC code to Israel so call recording is active for all those notes I cannot write down while driving and I get to carry just one device with 2 separate numbers thanks to a dual sim.
Ok, so back to my phone not being on the f... list :
Around Feb 10th, I got yet another email and SMS telling me it was my last opportunity to change or I MAY be disconnected after 2/22/22 ( funny choice of date huh?). I noticed that words on email and text messages had been changed from WILL NOT on Jul/2021 to MAY NOT work on Feb/2022. Since I know for a fact that my phone is VoLTE capable, I figured my S8+ would work as long as AT&T did not intentionally disconnected my line.
So, I took a crappy phoenix ATT phone and updated it's IMEI on my account via the ATT prepaid webpage. After getting "approval" from ATT's system, I put the SIM card in and used it for a full weekend. After that, I put the SIM card back to my S8+ and it is still going strong to date.
Today is March 1st, and I have been weary of ATT sneaking me out of their system but fortunately it has not happened yet. Needless to say, I have not updated my S8's IMEI on ATT's webpage and do not intend to do so.
Now, This "proves" that my phone is indeed capable of using VoLTE and HD , and all those things ATT said it would not do is just plain B.S.. if they disconnect me down the road I would definitely move to T Mobile although I would have some issues with the 50/50 international roaming and I still have 8 months left on my prepaid annual plan with ATT so, keeping my fingers crossed.
AT&T just wants to make more money out of selling new 5G devices while getting rid of their stocked 4G phones.
I wouldn't mind if they just plain out stated " If you do not buy from ATT then ATT will not support your device and will not sell service to you" then again, it would probably be a PR nightmare for them although they do that for WIFI calling anyways.
Ain't it funny how 2/22/22 is coincidentally a paycheck's time ( 2 weeks) after a new flagship phone (S22) was made available for purchase ?
Anyways, enough for ranting and conspiracy theories lol...
I have taken out and put back to my S8+ the SIM card two times in the past 9 days after 2/22/22 and my service is still in good standing.
Maybe if you got a new replacement phone that you don't like, you may swap back your SIM card and it MAY work just like mine is even if it is NOT ON THE INFAMOUS WHITE LIST.

Hi, I'm Newbie around here. I'd like to share my experience with ATT and my beloved S8+ this past few months:
Much like you and many others I started receiving texts from ATT by mid 2021 saying my phone would not work after Feb '22. Yes, every time they suspended my line I wasted 30~ 40 mins on the phone, listening how they would insist my S8+ was a 3G phone. It didn't matter that I offered to send them screenshots of my device showing the "VoLTE option" and "4G LTE" while both in the USA and Mexico. Thing is, they only based their saying on a st....id whitelist and all the reps are just talking heads.
I use an S8+ international version which is NOT on the dreaded list. and I am on the 300/year prepaid plan which allows roaming between Mexico and USA with no 50/50 usage limit.
I bought this phone on amazon for 350-ish bucks a couple of years ago and I love it!
I have to cross the Mexico/USA border very frequently and I need two separate numbers one on each country for business reasons so dual sim is a must. On the other hand, I receive lots and lots of phone calls while driving, this made me crave for android 8.1 when call recording was allowed by google, not the case anymore.

Yep... AT&T is full of it. I got sick of wasting my time and energy trying to fight this. I eventually just switched over to TMo, and I have been running around with my S8's radio set to LTE only. No issues whatsoever. Great cell service, $30 bucks a month cheaper, all fees included in the flat rate, and a free Netflix account, to boot.
See ya AT&T!!! I hope some group with the the gumption and time takes you to court for your deceptive trade practices. I hope you lose lots of customers, time, and money for your douchery!!!
Has anyone looked into potentially using ODIN to use AT&T's firmware on the unbranded G950U1 without rooting to see if it adds the VoLTE software feature? Does anyone know if that flashing will disable (permanently break) samsung pay? I don't want any rooting since that will permanently break samsung pay on the hardware.
