q? about using T889 on AT&T

my friend purchased a used Note 2 T889 from somewhere and the sticker on the back had a clean IMEI however the phones IMEI was actually different than the IMEI on the sticker and when we looked up the IMEI on the phone itself it was reported as lost phone.
So we were not able to get a new sim and register this phone to be used on Tmobile.
I went ahead and unlocked it and updated it to the latest firmware and it picks up the 4G-LTE on AT&T but its still running the Tmo firmware on it.
is there a way to install the ATT firmware onto this phone ? or any roms/firmwares with all the carrier branding removed ?

[Q] Can bad esn sprint LG G2 be sim unlock

a friend of mine gave me a bad esn sprint LG G2 that he bought off on craigslist. It has the ZVE firmware and I succesfully rooted it using stumproot. I install all of cloudyFa's roms on it, but for some odd reasons it won't pick up my tmobile simcard. I go to "phoneinfo" and no matter what I switch it to from WCDMA preferred to GSM only etc.... it just keeps saying "emergenc calls only" So i'm wondering if it's because of the bad esn that's keeping it from recognizing my Tmobile sim card. Anyone can help me?

Try a regular unlock on the device first.

regular unlock?
when you say regular unlock do you mean have the device unlock through Sprint first? I don't think Sprint will give the unlock code because the Sprint LG G2 has a bad esn. If what you mean by regular unlock refers to modifying the software then unfortunately that is something I'm not really good at, but I'm a risk taker - I don't mind attempting to do the regular unlock even if the bad esn sprint Lg g2 gets messed up in the process. Is there anyway at all for you to show me how to do the regular unlock? I saw in another topic about using Rom Toolbox lite to change some stuff, but when I install the Rom Toolbox lite app I have no idea how to use it - it's all very confusing.

I went to the link as you suggested and I downloaded the file that you provided, but it would not let me copy the folder carrier. I follow all the directions that was provided on the link, but when I check the carrier folder on the phone I notice there are only two folders. While the carrier folder on the TotalCMD folder had like 6 folders plus a file.

Hmm, not being a gsm user, I am not sure. Was there any information in the thread of someone else with the same issue.
One thing I think they didn't say was you have to be on zv7 or zv8. Unless further in the thread it says other wise. Still reading.

when I was handed the bad esn sprint LG G2, I checked the firmware and it was on ZVE firmware then I used LG Flash Tool and downgraded it back to ZV8 firmware. I have successfully rooted it also now on the ZV8 firmware. My brother-in-law has a sprint LG G2 and his work for tmobile, but only thing is his Sprint LG G2 has a clean esn/imei and mine don't. So i'm assuming mine is not working because of the bad esn. Oh well I will keep on trying and figuring out how to make it work.

eBay G7's - GSM unlocked, Sprint unlocked, unlocked - questions

I have purchased 3 G7's over past couple weeks, from the same seller (starts with "w", has a ton of phones). All of them were listed as G710ULM. Here is what I got:
1. One that was "grade B unlocked" came as model number LM-G710ULM, but with empty S/N. Android 8.0.
2. Second one was "grade A Sprint unlocked" came as model number LG-G710PM, has actual S/N, Android 9.0
3. Third one is same as #2.
I am assuming that #1 phone is also a PM model that wasn't unlocked properly.
With that being said, I wanted to make sure what my options are.
1. Can I properly unlock all 3 phones, so I can run updates on them? I plan to keep just 2 for now and #2 and #3 are in a bit better shape than #1.
2. I see a bunch of "GSM unlocked" ULM models that description mentions will not work for Sprint or Verizon. Is that really the case?
3. What other models are unlockable to be used on Sprint?
Thanks for help on this.

Anyone? I would appreciate some answers.

I got one as well, LG-G710ULM. Can not update via OTA (hence stuck on Android 8.0) since I am in the UK and according to LG UK support the IMEI corresponds to US carrier SP (Sprint they reckon). Kind of a bummer that you can not update your cell. Anyway, am also looking to update it, without jailbreaking it if possible.
Bump up this thread!

Its obvious those devices were just crossflashed with ulm software to gain unlock. That said, your best solution to getting an updated software will be to flash latest ulm firmware using lgup

OK, if you could clarify what G7 models can be flashed with ULM firmware, it would be great.
I am pretty sure I will return the "fake" ULM model and possibly keep the PM model - that's compatible with ULM firmware, correct?
What about ULM "GSM unlocked" models that per description don't work with Sprint?
Are there any other models that can be flashed with ULM too?

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)
[/LIST]

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?

Emergency calls only. HELP!

Hello
I bought a used s9 a few months back. It had dual sim. In "about phone" it said G960F and was on android 9. A few days ago, I wanted to flash android 10 so I downloaded firmware for G960F, booted my phone in download mode and SURPRISE. The whole thing was in Korean and of course it was a G960N model. So I downloaded firmware for G960N this time and flashed it. Everything went perfect but when the phone booted up, It had no sim service.
I've tried everything I've found on the forums so far related to emergency calls only or no sim service.
Any kind of help would be appreciated. I have no sim service for 5 days now.
Things I've tried so far:
Flashing my phone again with android 9 stock firmware, which I can't do anymore as I've updated the bootloader lol.
Flashing custom roms
Changing csc from SKC to KOO
Flashing OXM CSC as I live in Pakistan
Flashing different modems and basebands
Nothing worked

Try flashing back a G960F android 10 firmware.

Done all of that. No luck

OK, let's go back to beginning: you've bought the used phone. 960F never was (as factory leaving) dual sim phone.
so, let's start from the beginning:
contact the seller and ask what the hell have you bought (if it was any variant of the S9 at all.. somehow I doubt it).
2nd: write down the IMEI and serial number, and check with Samsung if this configuration ever existed (if not, what I suppose, the IMEI/sn info about the REAL model can give you a hint what have you bought).
Having the above info in hands, find the "service firmware", 5 files ROM for your device and try to flash it.
If it will not work still, I'm afraid you have two options:
1. check IMEI against stolen devices with your carrier.
2. Go to Samsung service asking for help.

Well mostly it isn't a fake mediatek phone as it will not even have a download mode.
Probably he bought a shi**ily refurbished phone with it's internals mixed from multiple versions of the s9, in the best case.(a Frankenstein variant of the S9)

I'm going to solve this mystery for both of you. The phone he bought is indeed an S9. Here in Pakistan, 'software' guys in shops can convert these to dual sim models with some z3x and Chimera f*kery.
As for why his phone isn't working - it is because the phone had a tampered IMEI to bypass local custom charges levied on all imported phones (insane charges, doubles the price of these kinda phones). Once he flashed a new image on his phone, his IMEI status would have become NG instead of OK, which prevents the phone from accessing any networks.
Solution is to visit the same 'software' guys, ask them to 'patch' the phone. It is a 5 minute process, requires root (which these phones already have).
