S9 with still on contract unlocked - Samsung Galaxy S9 Questions & Answers

Hi Everyone,
I'm expecting a CDMA/GSM s9 with bad ESN from sprint. I understand i can put GSM SIM and it should work, but will i still have to unlock it? and if yes, can it be done despite th ebad ESN. I read somewhere else someone that it could be flashed with VZN firmware using samfirm and then unlocked. Any ideas? Thanks

Baseband with the Metro ROM is G920T1UVU1AOCH, but the problem is, I flashed both of the S6's I have here to the Metro ROM to unlock them so I have no idea what the original baseband was lol I hope you do!
Any luck on the S6 Edge unlock? I scour the internet everyday for developments but I havent seen anything I feel like this S6 Edge I have is either going to sit here forever or Ill have to sell it as a blacklisted phone because its financed and I KNOW its going to get blocked.

the fact that baseband has a G920T1 means that it did changed the radio , while every damn firmware i tried never change the baseband ., is good to know though ... and if you have an S6 Edge try this before selling it .. ask to borrow someone's tmobile sim card and try to at least do a temporary unlock if that doesn't work then download the app VyprVPN select germany (i did) with the tmobile sim still in and try temporary unlock again,,, doing this at least it bought a month's use of my phone , maybe a solution will come up later on.

So youre saying that when you flash the Metro ROM to it, its not changing your baseband? I used the one posted by UnlockBase. Were you able to successfully unlock yours?
And yeah, Ive tried the TEMP and PERM unlock on the S6 Edge. I put my TMobile dealer SIM in it hoping that would help as its a free $80 monthly demo line I get for selling TMobile service. I would gladly try that method, but since we sell these phones, a TEMP unlock wont help me I need a permanent solution so once I sell it, Ill know the customer wont have any issues down the road. I have both of the S6's up for sale now that they are unlocked, but I have always wondered if Samsung REGION LOCKS these phones. Ive tested my personal ATT line in it, and it works great, but alot of my customers on eBay export these phones overseas, so Im hoping these new Samsungs arent region locked :/

when you try to flash any firmware with odin it ends on FAIL.. you can flash rom with twrp but baseband remains the same ,, so i dont know if the unlock app from tmobile is tied in the bootloader or radio or something else ... so far i'll just enjoy the 30days left and see what happens after that ... cause after it accepted my att sim card a message will appear reminding me the unlock was to end on Jul01 and if i wanna to do permanent unlock, so i flash a firmware from a canada version G925W so the reminder went away but i dont know if that means that in 30 days i'll be locked again

I gotcha. I did something similar. I flashed the international ROM on the S6 EDGE via TWRP and it told me the code is incorrect. I know the code is correct because if I ever it in with no SIM and the #7465625*638*# and put the code in it says successfull. This is SOOOOOO frustrating. The lock has to do with the radio or the bootloader/baseband.

I am interested to see if that works which it may as the app is not there to retrigger the lock. You never know.
I currently have metro pcs and I bout an unlocked Samsung galaxy s6. My original Sim is too big so I have to go to metro to get a new one but the phone is not reading the new sim in order for them to program it. How do I fix this or get around this? Should I not let metro try to activate the phone?

Need somebody to help me about network unlock.

I'm sorry but I have some questions. Hope you guys can help me out.
1. Can I flash the U1 firmware(unlocked) to get sim unlocked on my T-mobile S8+?
Because I'm not American, I need to sim unlocked my phone to use my country's carrier.
2. If the first one doesn't work, can I flash the s8+ sprint firmware on my s8+ T-mobile and after that can I sim unlock the T-mobile s8+ with buying the Sprint unlock code?
Because in my country, T-mobile sim unlock is much higher than the others.
Forgive me if my worse Engish bothered you.
Thank you so much.

From what I know it has to be unlocked through tmobile. Flashing different firmwares won't do anything and in the case of the u1 firmware all it does is remove carrier apps it does not unlock the phone to be used on other carriers.

Verizon Note 8...T-Mobile sim - help

Hello all, new here and I just purchased a Note 8 from Verizon. The device is paid off fully and i wish to use my T-Mobile simcard in it but it does not seem to be picking up a signal. I did update the verizon software to the latest version when i had my verizon sim card inserted. Verizon customer service told me i need to reset to factor setting then my t-mobile sim should work but this has not helped.
How can i get my t-mobile sim to work? Any help appreciated as i am new to android phones!
Thanks
Hi there, you must flash the new N950U1 2BQK1 or N950U 2BQK2 stock firmware to have full access of T-MOBILE Network. It's the only way it will work, I have AT&T NOTE 8 working on Verizon network with zero problem.

It's a very easy process to flash the 4 US Carriers firmware, I have done it more than 50 times and I'm not a developer.

I would like to know where to get the firmware and with what do you flash it with? Is there a instructions thread or link.
It's been over 5 years since I have tinkered with a Samsung device.
Hi there. You'll need to have your Note 8 Bootloader version on level 2, meaning 2BQK2, 2BQJA or anything with 2 before the last 4 digits.
1) tmobile SIM card in device
2) Odin v3.12.7 make sure extract
3) 2BQK2 firmware extract all files
4) put all 4 set of firmware files in the right manner, bl,ap,cp and csc. Don't used home-csc only CSC.

Unlock firmware
1) any carrier SIM card
2) Odin v3.12.5 Prince Comsey or modified Odin, make sure extract
3) 2BQK1 firmware, extract all files.

First instructions is for if you want stock US CARRIER BLOATWARE FIRMWARE, second instructions is if you want SAMSUNG STOCK FIRMWARE. Follow steps and everything will be fine, happy flashing.
So wait, I have a Verizon Note 8 (currently using MetroPCS perfectly), but I wanted a stock Samsung ROM (without the Verizon crap on it), I can just flash the second set of files instead and done with it?
Yes
Can I use a gsm sim card and a verizon sim card at the same time on verizon branded phone? I see you have to flash the firmware above but am wondering if this would help me.
So much misinformation in this thread.
I don't even know where to start:
The OP was asking why his T-Monile SIM wouldn't work. It doesnt matter which firmware you're on, if the Note 8 is unlocked (the Verizon Note 8 IS unlocked), and it has a clean IMEI, and your SIM is already activated, then it will get 4G LTE. I know. I have a Verizon Note 8, and use it on Tmobile. I used it for over 24 hours with my T-Mo SIM but running thr Verizon firmware with no issues. Only reason I flashed T-Mobile firmware was to rid myself of Verizon bloat and to get wifi calling.
As far as bootloader, that has no effect on the SIM card working. The OP would need a v2 bootloader firmware if his current firmwarealso had the v2 bootload. It probably does, so thats a moot point, but the implication was the v2 bootloader was the only one that would make his SIM work.
I hope the OP got it all figured out.

plus the second SIM wouldn't have an IMEI assigned to it.
And I agree the OPs best bet is to flash thr T-Mobile firmware. But his issue was he wasnt getting a signal at all with his T-Mo SIM. Flashing firmware won't fix that. Source: I have a VZW Note 8 on T-Mo. Used it with the VZW firmware and a T-Mo SIM with no issues.

Another user had SIM issues and flashed back to factory (theirs was unlocked) then changed carriers and SIM worked again...sometimes a clean flash can work...
Hi all. For me I flash all firmware at clean wipe, never any issues. I have an unlock AT&T Note 8 unlock running the latest Verizon firmware with VZW SIM active. I also have a t-mobile S8+ unlock and running the latest U1 firmware and working with Verizon SIM active. I constantly switch my firmware between tmobile, verizon and at&t to see performance and what ever else feature added.

How did you get ATT N8 to work on VZW? I flashed my Tmo to VZW and i could never get speeds above 1mpbs. Even with unlocked firmware it did not get anywhere with VZW. I heard that its because the IMEI is not in VZWs database.
Hi there. My AT&T Note 8 works great on Verizon network, it's running the latest N950U1 Firmware 2BQL2, everything works great. It will work good on T-Mobile too, lately tmobile network giving trouble, sometimes less than 1 mbps on download. Since June 2017 I been having trouble with tmobile network in my area and around, so I switch to Verizon, couldn't bother the crappie service. My location I get 215 mbps on my note 8, IPhone 8 plus 147mbps download. I prefer Tmobile but it's not working good in area anymore.

@Mr. Orange 645
I currently have a Verizon Note 8 with a TMO SIM and I'm getting 4GLTE but a few problems. Most of the incoming calls forward to voicemail and all outgoing calls the data has to drop completely before the call can connect. Will doing the carrier switching updates listed in the link above as well as flashing T-Mobile firmware assist with this problem? The phone is on 2BQK2 currently.

Verizion note8 with tmobile sim card
This is what happened when I changed carriers from the original verizon note8, on verizon network, with verizon sim and the most recent verizon pie update, to a carriers sim, that is tmobile service. And what happens, I didn't even think was possible... I put the new carriers sim in, truconnect, booted and let the phone register the new sim and network. Checked for update.... the was one, let the phone download and update. And you know how Verizon's boot logo is... it wasn't anymore. Booted the tmobile boot logo and sounds, strange. I'm not super noob and the little bit of knowledge and experience that I do have with roms and updates across carriers usually require physically flashing the rom. Correct me if I'm mistaking. Continuing.... optimizing apps....., huh?! The update flashed the tmobile software, without effecting any personally installed apps. Though the update did remove all the verzion software/bloatware, without permissions, and installed tmobile apps. 2 that are meant for user usage. They are tmobiles device unlock and the tmobile app. Which I might add, do not function, I surmise, because in not on the actual main tmobile network, but a scabbed on. I have never seen or experienced anything of the short. Please tell me if this is normal.? I was a bit upset. I did not give any carrier the permission to delete or install any app on my phone. But maybe things have changed since I dabbled. And If they have, maybe this might help the people that have been using Odin to get tmobile version rom while originally being a verzion phone. I dont think it's normal. Please tell me if this has happened to you.

Noob question, How do I root Hd1907.

I just got my phone yesterday, from amazon. It is factory unlocked and despite it being a hd1907, it has no tmobile software on it. My carrier is also Tmobile. The guides are slightly confusing to me, as I am not sure if factory unlocked is the same as having my sim unlocked? Also is it possible my phone already has the international rom on it? Thank you in advance.
Edit: Build number is 10.0.15.HD65AA

unlock bootloader for g988u verizon

New to flashing and unlocking bootloaders. Accidentally came upon the download screen and wanted to learn more. I have a samsung galaxy s20 ultra 5g g988u but from Verizon. Ive read everything i could and still confused. Can anyone help me out with anything. Lol i just want to learn
U.S. variant of Samsung phones cannot be bootloader unlocked. Everything you read online most likely is referencing the international version, which can be unlocked no problem. The only way you can unlock a U.S. variant phone is by paying a service fee (search for SamPWND).
