Rooted LG P935 need clarification about Network/Carrier Locking

So ive gone ahead rooted my P935 many times now quite simple to do. The question is its a Telus phone i'm with rogers, when i flash the v10f kdz i get origninal GB korean rom fully unlocked phone shows using rogers network. When then doing nitro hd unbrick guide and if i only DD the system.img file to install the att version p930 then do the battery pull factory reset my phone still is network unlocked. What i'm tryin to find out is which .img files baseband firmware etc would control this network lock, since when i tried to flash H!ONO v20c P930 cmw flashable ics leak my phone became network locked again. Ijust cant seem to straighten it all out , information overload .

That's very strange, flashing ROMs should not affect network lock. I'm using Bell P930 on Fido, I've flashed AT&T leak and Bell official ICS and neither have re-locked the phone. As long as the IMEI remains unchanged you should be able to use the original unlock code you received to unlock the phone again.

Interesting indeed would it be the v10f .kdz korean somehow. And heres the thing I have recieved no unlock code to unlock. And now am back to running the CM9.1 unlocked working on Rogers Network .

Aha! I figured it out. CM has your Rogers APN preconfigured. The official roms would not lol. I don't know why the SU640 rom was letting you connect. It really shouldn't because your firmware and baseband should be incorrect if you flash it. Anyway, APN has nothing to do with your phone being locked or not

w0095157, are you certain your phone was never carrier unlocked by someone? Did you purchase it brand new in box from a store?

brand new in box i swear, telus store,. must be a fluke. but it works id like to find more information on different radios modems, which may change service for me, but i was comparing this to what iphone 4 service was saying side b y side.

Yeah, that makes more sense. Unlock codes are $2 off of eBay, it's worth it just to make sure you don't have any hassles switching between ROMs.

Does LTE work on Rogers when using the Bell unlocked version (P930)?
I know you have to get an LTE Sim card and an LTE enabled plan, but before i buy on eBay and update my plan, i was wondering if the LTE band works on Rogers even if it is a Bell phone.
Yes, i have LTE in my area.
Cheers!

I don't live in Canada, but from what I'm able to find online, Rogers and Bell are using compatible LTE frequencies so it should work just fine.

It works!!!

So after trying million and 1 things I made it work! Baseband and firmware go together and I thought they contain the SIM/network lock so i tried changing them, but apparently all the versions i tried were locked too.... so since the Korean version is with unlocked SIM, why not change directly from it to Cyanogen build ??? Because the wifi is not working!!! and since i did not manage to fine how to install in while offline (CM or Clockworkmod) i flashed from the Korean version just the system.img and voila! I have unlocked SIM with working WIFI ... so putting CM after this was a breeze!
so:
1. flash to Korean V10F_00.kdz
2. root the phone
3.adb shell
su
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
should have unlocked SIM + everything else working on the ATT version which you can now install Clockworkmod and go for Cyanogen mod of your choice. i did cm-10-20121105-NIGHTLY-p930.zip - works great!

I have a p930 with at&t permanent locked network, I discovered too that the baseband of the korean version is unlocked, I made a thread about this but nobody commented or cared i think lol, you can install any rom you want but remove the baseband of the rom before install.

Ok I have a similar problem with an at&t Lp 930, did the unbrick guide to sim unlock with the korean baseband. While in the koream ROM sim was succesfully unlocked. But after following the guide, flashing to AT&T Gingerbread and installing ClockWork Mod, I flashed it to HO!NO! AT&T ICS CWM Flashable ROM once in ICS, I lost Sim Unlock and was back to: Network Locked on Phone.
So what your saying is to basically only flash the system.img after the korean ROM is on the phone and ignore the other images, then after flash to desired ROM with CWM?
And if so, if I flashed to HO!NO! At&t flash, would I still have Locked Network?
Thank You

How can I update firmware?

Hello,
I live in Korea and not an AT&T carrier user. So, I have never received AT&T's OTA.
I tried to connect my Galaxy S7 Active to Samsung Smart Switch, but Samsung Smart Switch says my phone's firmware is the newest version.
My phone's baseband version is G891AUCU1APE7, and build number is MMB29M.G891AUCU1APE7.
Am I unable to update my phone forever?
I want to update my phone's firmware.
I desperately need your help...
Thank you.

ATT only updates there phones OTA... you have to be on the att network to get it to update.

+1 Not AT&T Carrier
But I see S6 Active can in PC updata I think can use the same method to upgrade

Given that they allow unlocking of the device, that is a ridiculous policy. I can only hope that someone will be able to download the image so that we can use odin.

looking on the S6 Active thread, they find the update downloads on AT&T site, not sure how ?? you can easily find out WHAT update is the newest ..
then either flash via Odin, or 'side' load it ...
but i couldnt find out how they were getting the links from AT&T site to download direct ..

Updating outside USA
in order to update this device outside of USA you should get a At&t SIM card (whit active account), put and seek for updates and will work, I made it a couple of hours and I was able to update.....All this thanks to a friend who lives in Usa and came to visit my country and lend his sim card to do the test ...

Do AT&T have such things as pre-paid sim cards? And could I activate one outside of the USA?

bandario said:

It exists and is called GoPhone, only you would have to do it through some friend or trustworthy person who lives in the USA and can buy it and send it to your country ... is what I will do for the next updates

(Was a scam site, sorry)

now we have these phones rooted, could people in the US with a OTA updates, pull /dump the updates
for us people outside US to flash via Odin ? ...

I'm looking into purchasing this device but have second thoughts due to firmware update availability (not to mention custom ROM support).
Anyway, related to the topic above, I have an AT&T prepaid GO Phone SIM but it is already deactivated/expired. Can I use this old prepaid SIM to update the device firmware outside US?
Side question, what is the difference between SM-G891 and SM-G891A? I see it often when looking for this device.
Thanks.

Hi aalam .. did you face any issues with update using Odin .. I want to update my device but I'm afraid that I might brick it in the process .. this is not the first time that I update a device using Odin but normally it's just one file and I never needed to use the pit file.
appreciate if you can tell me the status of the device after the update ..

S9 Message Your current software version isn't supported. Visit a service centre

Hi first post, please be gentle
I've got an s9 which is on EE UK, I flashed the phone with stock firmware, I did run into a couple of issues where when flashing the phone it got stuck on odm.img so I had to start again but using CSC and not home CSC so I lost everything
When the phone rebooted, it started up in German, so as I had my sim card in, it restarted in English
I'm using the following
G960FXXU2CSA2/G960FOXM2CSA2/G960FXXS2BRK3
Service provider SW SAOMC_SM-G960F_OXM_DBT_PP_0009
DBT/XEU/EVR
When I check for updates I get the following
Your current software version isn't supported. Visit a service centre
Can anyone help on how to put this right, I want to stay on stock firmware, not EE firmware
Thanks in advance

Good morning, I have a problem with my S9 model G9600 which came from the factory with the firmware of Hong Kong, however I tried to change the firmware for the one in Colombia because some voice services of the operators only work with the software of the country. But when trying to flash the part of CSC I mark the error and obviously the installation fails as in a kind of A brick because the logo of Galaxy S9 does not pass and is only solved by reinstalling the firmware with which it came from the factory; I have already made sure that the binary is the same, however I can not find a solution. I attach photos of the error.

You need to flash the XEU firmware, you have the German DBT firmware running right now

same issue, i have a hungarian telenor phone which suppoesed to be (PAN) , i flashed XEH which is hungarian, but it said software version not supported visit a support center , so i flashed the PAN 9.0 version and it still says this

Did you find any solution for this?

are you having an identical issue? i ask that because resolutions are very specific. Flashing firmware from www.sammobile.com/firmwares is very commonly the fix for a great many issues, but id hate to have you go thru the trouble of doing so if its not necessary

I tried flashing using odin but didnt work. btw, im using SM-965U and currently residing in Thailand. I dont know if this is the reason why I cant update at all.

S9 message
I am in the U.S. and am getting the message that software isn't supported also. Is there any resolution to this problem?

In case it helps, I was having this same issue with my unlocked Galaxy Note 10+. I found this thread after searching. I had gotten into this situation by flashing CP/AP/BL from TMO firmware without also flashing TMO's CSC or USERDATA. I avoided CSC/USERDATA (I was using the home CSC) because I wanted to avoid wiping the phone.
When I finally gave up and flashed CSC and USERDATA, everything was back to normal.

Help Flashing Samsung Galaxy S10+ from VZW to Strait-Talk

Hey everyone,
I'm new to flashing phones but have experience flashing other hardware; still, I felt it prudent to ask for some guidance on this being my first attempt:
I have a Straight-Talk phone which is active and working with 4G that I would like to swap the SIM over to use in my Galaxy S10+ from Verizon.
Swapping the SIM without flashing limited the functionality to be contingent on WiFi; 4G would not work correctly.
So I suspect I'll need to flash with unlocked firmware to get it to work properly.
I have downloaded the G975U1_SAU_1.zip which is what I think I'll be needing to pull this off, as well as the latest available download of Odin (3.14.1).
Before I get started, I'd just like to ask some Questions:
Should I leave the intended SIM (Straight-Talk) in the S10+ (Verizon) while I'm flashing, or insert it after the flashing?
Am I using the correct firmware to flash this Verizon phone to work with Strait-Talk? (United States regions)
Also should I back up the intended SIM in some fashion before proceeding with this process (if so what software if any would be advisable for this?)
Is there anything I need to watch out for?
Am I on the right track for what I'm attempting to do?
Thanks in advanced for any help! :highfive:

Insert SIM after flashing. You need the current U1 firmware from sam mobile. You also need the patched version of Odin that's floating around the forums here. No need to backup your SIM, but using Odin will reset your phone to brand new. Nothing that I can think of, you just put the correct Odin file in each slot and hit go. Seems like you're onto it, you need 3 things which are patched Odin, latest firmware, and I think phone drivers so your PC recognizes the phone. Should be able to find these on Samsung website or other parts of the web.

Thanks for the support!
After your encouragement, I rechecked my firmware made sure to acquire the USB Drivers from Samsung.
Successfully flashed the phone and its now working as intended!
:victory:
I used the Frija tool mentioned here to make sure I had the right files.
And the Driver install came from here.
Thanks again for your support! :highfive:

No problem man, glad to help. Good you posted links too so others can do the same if they're having issues.

Absolutely!
Anything I can do to help pay it forward.
I should also mention I got my CSC code from the list posted at
Droid Views dot com /how-to-change-csc-in-samsung-galaxy-phones/
(Won't let me post the outside link given that I'm new)
The code was required to use Frija to download the correct firmware.
(The 4GB download averaged at 2.5MB/s)
Here is the list I saw on the aforementioned page; I used XAA
Code:
[LIST]
[*]ACG – Nextech/C Spire
[*]ATT – AT&T
[*]CCT – Comcast
[*]LRA – Bluegrass Cellular
[*]SPR – Sprint (CDMA)
[*]TFN – Tracfone
[*]TMB – T-Mobile
[*]USC – US Cellular
[*]VMU – Virgin Mobile USA
[*]VZW – Verizon
[*]XAA – USA (unbranded/unlocked/default)
[*]XAS – USA (unbranded/unlocked)

Random questions:
If you start with a Tmobile GM-S975U that is carrier unlocked (got unlock code from tmobile)
Will it work just fine with straight talk? If not Does changing the CSC code work, and to which code?
Is different firmware required? like U1?

The U1 software for the S-10 plus is strait from Samsung and has no carrier bloat. All US S-10 pluses are the same, no matter who the carrier is. That means you can flash any vendors rom as long as you don't go backwards on the bootloader version. The phone gets set up by the simm card installed on the first boot. The good things about the U1 software is there is no vendor bloat and your updates come straight from Samsung. Don't forget, you have to us the customized Odin to flash with.
Deatailed info and Odin link can be found here. https://forum.xda-developers.com/s10-plus/how-to/guide-g975f-flashing-megathread-faqs-t3936704

Thanks for the reply. Should straight talk just work? My friend says data isn’t working on tmo firmware. What firmware and Csc code would work with them?

curious, do mobile Hotspot work, or is carrier still able to block it?

A little help with flash firmware

Hello guys. I am from Europe and just buy Samsung Galaxy S20 Ultra with Snapdragon. The phone is unlocked, but have carrier brand, Verizon, I want to remove it. Can't change phone language (see that this problem is discussed here, but I did not see a solution) and in Verizon miss Samsung Cloud.
I decided to try changing stock rom with Odin. Now downloading official firmware SM 988U, because I read that must put firmware with "U", and downloading SM-988USQU1CTLB (this is my baseband version and hope that this is correct firmware), write only USA, without any brands, from sammobile, I hope that is without carrier brand. Don't know if I will manage to change language successfully, because the phone is made for USA, but hope that carrier brand will disappear and Samsung Cloud will show. Will do this for first time and don't understand a lot of things. However, my question is for Bootloader.... I try to see if my bootloader is unlocked or locked, but can't do it.... If I put new firmware and bootloader is locked what will happens? Sorry for my stupid question, but I try to learn how things happen What you think, is my idea is good or no?

Something is bricks. I downloaded the original stock firmware from sammobile. USA only, I successfully uploaded it, everything with Odin was good, but after restarting and entering my sim card pin code, the phone want pin code to get app notifications. Please someone help me.... What is this pin code? I can only received phone calls

I manage to put the phone in downloading mod, please someone tell me witch firmware must download and install? The phone is SM-988U
