Need some help if possible - Android Q&A, Help & Troubleshooting

Hi Guys, I apologize if this is in the wrong forum. Noobie to this forum as i am stuck with a phone I can't get to work. I just bought a used phone which was made for the US market. It's an unlocked Verizon Galaxy S5. When I first turned on the phone and saw the Verizon logo I was a bit annoyed as I did not think an unlocked phone would have a propietary logo. So I tried to flash the phone with Odin. As I am with Bell Canada I tried to flash the Bell Canada ROM, but it wouldn't work. I tried looking for a ROM that would allow me on the Bell network but I did not find one that would actually take. I kept getting write error and the flash would fail.
I was finally able to successfully use Odin to flash the phone,. SO right now I have the latest ROM for the Galaxy S5 for USA.
Can someone point me in the proper direction as to which ROM i should be trying to get this phone to work on the Bell network and use 4g/LTE? Right now this USA ROM is not allowing me to connect with the 4g network. I can only call someone on wifi, which is pretty useless to me.

Are you sure you're in an area with coverage? That happens to my Ace sometimes even with 3+ bars of signal. But it depends where I'm at. Try changing your location

I found the solution for this issue.
For Telus or Koodo only. Those who flashed with a custom rom and cannot connect to Telus or Koodo and get "Emergency Calls Only", do this:
Download Modem_S5830DTLKI4.zip here:

Then flash your Samsung Ace with this file on top of the custom rom and it should apply the correct baseband for Telus/Koodo.
Enjoy!

[Q] Can't seem to fully reflash SG Note 2 with stock ROM. Help please!

Hi, and firstly, thanks to any and all who offer their knowledge to assist my conundrum.
I recently purchased a Bell Canada version of the SG Note 2 (i317), I am on Telus so I attempted to Unlock the phone. I looked online and found people were having success unlocking these phones for free using the *#197327640# method, (whereby you go into the service mode, turn off the PERSHO_256 and then INITIALLIZ).
I tried this method and the phone then seemed to work with my telus sim, but only for voice, not data. When I put in a Bell SIM from a friend, both voice and data worked fine - which tells me its not a hardware (radio) issue. I also tried using another friends Telus SIM and had the same results as mine - which tells me it's not a SIM error. Also, all the settings in the mobile network area appeared to be correctly set up.
So, my next step was to try and reflash the phone to the stock Bell ROM and then just buy an Unlock code. I downloaded the stock ROM (2 different ones actually) and used Odin 3.07 to reload the ROM. I've tried it several times now, with both Bell ROMs and each time it says it's been successful, but the phone remains in the same, partially unlocked state.
It seems as though by using the PERSHO_256 method I have permanently, PARTIALLY unlocked the phone. I can't seem to re-lock it by installing the stock Bell ROM, and since it's unlocked, I can't get the foreign SIM error to come up to enable me to put in my purchased unlock code.
If anyone has any insights, it would be GREATLY appreciated. Thanks!

You should ask questions about a specific device in its own Q&A. (unless it doesn't have one). Cuz people there have the same phone and will know exactly what to do.
LIFE! IT'S WHAT YOU MAKE OUT OF IT!
Will do, thanks for the tip!

[Q] Bricked Galaxy Mega 6.3 SGH-M819N

Every time I try to flash with odin I get a security failed tz.
Do you have any idea what this can be?
Also when I try to go into recovery mode i get "Secure Fail: KERNEL"
I have the SGH-M819N, this all began when I wanted to switch from MetroPCS to Net10.
Because Metro's service is really bad, everywhere I go is like a dead zone.
Mind you i live in the city of Miami. lol
So the wonderful people at Metro wouldn't give me an unlock code for my phone.
I don't understand why, if Metro is a "NO CONTRACT" company.
Any ways, i took it to the flea market by my house to get it unlocked for $40
The gentleman that worked on my my phone instead of just telling me it can't be done, decided to flash my phone to AT&T SGH-i527 voiding my warranty completely.
Can someone please help me?
I have a $550 paper weight at the moment.
When I try to boot in recovery mode it says "System software not authorized by AT&T has been found on your phone. Please turn off your phone and go to the nearest ATT store for help.
And when i try to turn on my phone it just stays in the AT&T logo.

Any help will be greatly appreciated. :fingers-crossed:

Thank you for the info I was excited to see the thread and did everything step by step, but when i get to the part to enter the
serial #, for some odd reason Kies says that it is wrong, to please check and re-enter.
I'm sure i have the right #, its on the back of handset and receipt.
I think the problem with this is that your phone is a metro pcs mega and you're trying to put in the (metro pcs) serial number to download an AT&T Mega firmware. I don't think kies will let you do that and there currently is no firmware available for the metro pcs mega so kies may not work for you at all. You may need to sesrch to see if you can dowload the odin flashable firmware another way ( perhaps someone in the mega forum actually has it somewhere). Somebody correct me if I'm wrong.
Sent from my SGH-M819N using xda app-developers app
I think the GT-I9205/9200 are closer to Metro's version of the phone. Their ROM's work on the Metro version. Maybe try their firmware. Unfortunately Metro's firmware isn't out yet. Metro Locks the phone for 3 months. After the 3months of service they will unlock it.

Can i put UK H3G firmware on and American ATT device? AT&T to 3

The reason i want to do this is i own an ATT s6 edge (SM-G925A) but im in the uk and im on the H3G (3) network. It is network unlocked. It would be nice if the phone acted as if i had bought it here (able to update OTA, boot with 3 logo etc). I found the firmware on sammobile (SM-G920F), it was only a single file though, using Odin3 i loaded it into the AP tab, but i just got a fail and a soft brick which i fixed with the original ATT firmware that has 4 files. AP,BL,CP and CSC. I'll admit i'm not sure what they do individually.
I really want to know, is what i'm trying to do even possible and if so, where if i needed, can i get a more complete firmware file? I'd be really grateful of any help or advice, thanks.

Unlocked frp on s7 edge sm-g935a and flashed t mobile stock 7.0 rom. Sim unlock help

New to android rooting/developing. Ihave searched countless hours looking for help with the issue im having. Whicj brings me here to seek help.
I bought a s7 on AT&T network. It was google FRP locked. After a few hours of getting through it with help from online tutorial, I realised it was locked when I put my tmobile sim into it.
Since I wanted volte and mms to work,(as it does not on my current verizon unlocked s7e) I used odin to flash the latest t mobile version on 7.0 on the g935. All went well but there one issue.
After tmobile ota updates that ran after I put my t mobile sim in it still won't work. Guessing the sim is still locked. But I do not get the device unlock pop up like I did before the odin firmware flash. Tmobile device unlock is not working, some error server etc.
How do I unlock this phone so I can pop my tmobile sim in and get the phone I've been working for... Lol. Thanks in advance. You guys are so helpful with all this.
