I purchased an att gs9+ directly from samsung, after that, I installed the unlocked firmware. Up to this point, I have used an att sim. When I tried to use a tmobile sim recently, I got a message saying "Invalid SIM card inserted - This SIM card is not supported. I was surprised as I thought it was unlocked since I installed the firmware. I then tried to install a version of the ATT firmare thinking I perhaps still needed to unlock it? At any rate, I tried but ODIN gave me the following error: FAIL!(auth).
So, first question is - If I installed unlocked firmware on my att gs9+, is it truly unlocked?
Second question, can I install the att version back again? Or perhaps the tmobile?
Finally - what does the ODIN error mean?
Thanks for taking the time to read,

SIM unlock is a completely separate thing which you'd need to use an unlocking service for, nothing to do with the firmware
Check the bootloader version your phone is running now, vs the one you're trying to flash, you cannot downgrade the BL
Download mode will show BL:1 or BL:2)
Firmware shows it here
G960FXXU2BRGA
Flash an equal or higher BL

Ok, thanks for the response.
I can see that my bootloader version is 3. I dont see any ATT versions out there for 3 though. Am I correct in thinking that I would need an ATT firmware to even get the sim card unlock prompt? Thats really the issue for me.. I am unable to unlock the device despite trying to reinsert, and running those #XXX*# codes.

nvm...Im not sure if by dumb luck, or putting on several firmwares and clearing things out.. it finally prompted me. wtf...
Thanks for the advice. I learned a few things about the firmware.

Good stuff :good:
Disclaimer: I am not responsible for any bricks/ issues you may encounter following this guide. Although, I will do my best to try to help you if something were to go wrong.
MAKE SURE OEM UNLOCK IS ENABLED UNDER DEV SETTINGS BEFORE YOU DO ANYTHING BELOW
Update 2: 3/11/2021 : I see maybe deleting the .ta files may help avoid soft bricking, feel free to try it I have not personally tested yet to see if it works.
Update#3 3/13/2021 : If you are following this guide recently make sure you update to Android 11 first! Do not do any updates after the first one to Android 11! Then the flashing should work just fine. Tested and verified this on Taiwan XQ-AT52 to 51 firmware
Hello, I've managed to successfully flash AT51 firmware on my AT52 without issue using Newflasher.
Step 1 download = the US firmware/ whatever region is needed for you and new flasher/ the sony xperia drivers needed to flash the firmware to your device. Extract it to your desktop. Install the Xperia driver from newflasher if you need to/ haven't yet. Newflasher needs to be extracted into the same folder where the firmware files are that you downloaded from Xperifirm. This step is crucial!
Step 2 : Power off your Xperia and put it in flash mode by pressing down on the volume and connecting it to your PC via usb. (Do not use the USB C cable that came with the phone use a different one if you have one) You'll know it is in flashmode if the notification LED turned green and the screen remains off.
Step 3 : Open newflasher.exe
Step 4: type n then press enter
Step 5: type n again and press enter
Step 6 : This is when you should get to the flashing stage. Press Y and enter to everything you are prompted to. type y for yes to. This for me resulted in a successful conversion over to AT51.
Step 7: Once everything is done and it says you are safe to disconnect your phone please do so and then press and hold your power button until the phone boots up.
At this point you should have a fully working AT51 firmware!
Bare with me as I"m working on getting developer access for androidfilehost and will upload the files asap. In the meantime you can download newflasher and the firmware files yourself using Xperifirm if you don't wanna wait for me to upload.

Can you please help? I followed and i got a corrupted message and power off in 5 second.

Can you tell me the model of your xperia phone? If you can still get it into flash mode when the notification LED turns green you may still be able to recover it.
Hi, I finally managed to restore it. I have to remove all the ta files to flash it, then it booted up.
Thanks for your respond.

I have using newflasher
After using 3 time xperia companion it work normal again
Hi, I didn't find this thread until after I made an attempt at flashing the device. I followed the instructions from the link below and ended up with the device saying it's corrupted.
https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/
I tried redownloading newflasher as well as redownloading the firmware I wanted as well as a new cable and that did not help. I reflashed it with this procedure listed above and it did not help.
Xperia companion won't let me do anything because it says the device is locked even though the device was not locked and there doesn't appear to be a way to unlock it. edited to add that I did get xperia companion to repair it successfully
edit again to advise I succeeded only after doing n and enter a third time then hitting y and enter for the final flashing step and that was successful in getting it updated correctly
Would it work to unlock my phone
Thanks for the guide!
Can I ask few questions please?
First is do I need to have my bootloader unlocked? I enabled OEM unlock setting in developer settings but that is only one thing I did.
And the second one is could this flash unlock my phone?
I am in this situation where my AT51 won't work with other sims except for Vodafone. UK.
I stayed with them for 30 days, (required time frame to get your phone unlocked) requested unlock code and it has been more than 10 working days but still have not received the code.
So today I did some searching online and found the service code to check if my phone is locked to a network and to my surprise it says it's not. So I am guessing that they have limited my phone to using only their sim through some other means andnot buy locking my modem. But this is ofc just a guess.
I kept chatting with the customer support and he keeps saying wait for the code which I do not believe is going to come, they have to unlock it on their end. But I am not sure about that. I don't think they are sure either..
Basically I'll wait fem more days maybe they will unlock it but if they won't when I am thinking maybe my modem is not locked and I could unlock it by flashing different ROM?
Or do you think this won't work?
Sorry for a rambling post. Looking forward to your reply. Thanks!

You do not need the bootloader unlocked as you are flashing official firmware.
Anyone know if you can flash a XQ-AT52 to a XQ-AT51 and then back to the XQ-AT52 firmware?
Sent from my XQ-AT52 using Tapatalk
I know this thread is a few months old at this point but I'm really struggling to flash to XQ-AT51. I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.
My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.
So I was able to flash from the hong kong version to the Taiwan version and back with no issues at all. But I'm still unable to flash to the US version without the "Your device is corrupt It can't be trusted and will not boot" error that seems to happen every single time I try to install the US firmware.
Can someone make me a favor and can upload the latest ftf of Android 10 for the Xperia 1ii Single SIM?

The 1 II has downgrade protection, so as long as the firmware version of the US version isn't the same or newer than the highest version you've ever used you're gonna get the corruption error.
What you could try is flashing the newer EU version and then flashing only the older US customisation image. That's what I did for a while since US firmware was older than EU firmware, and it worked. Not sure if it'll work with Android 11.

im in the us and was looking to the 256gb version (i think its taiwan). is the hong kong or taiwan version missing anything? or is the only reason to flash to US to get better coverage with us carriers?

It's for better coverage and for VoLTE and Wi-Fi calling support. Also if you get a HK one with Android 11 you will be unable to flash the US firmware, because it is still on Android 10; and the phone has anti-rollback protection.
it arrived on 10 still, but its bugging me to update.

This isn't the case now since the US models have Android 11 too now
Can anyone confirm that this process has to be done using USB 2.x? I've read in a separate post that newflasher isn't compatible with USB 3.x, which is currently what all my computer use. Also, should I be using the newest version newflasher?
EDIT: Tried on USB 2.0 and it worked perfectly.
SOLVED: use this tool. it's amazing: https://forum.xda-developers.com/t/...ader-unlock-enabler-engineer-decrypt.4378651/

after bricking the phone i had to use MSM tool linked on XDA. the problem is after the process ended my phone is not the same. it used to be LE2125.
now it's LE2120. and OEM unlock option is greyed out, so i cant unlock the bootloader. on the same option, it tells me to use network or contact the carrier, the first one doesnt work and dont know what the last one means, this phone was bought third-hand. is there any way i can solve this so i can install LineageOS?

Hey bud, I'm almost sure you don't have a sim in it, insert a sim card for the phone to be able to check if it's blocked by your carrier, even though it's unlocked, I have the same phone( Chinese version) and everytime that's what I need to do after msm back to stock. Stay safe.

I'm trying to root and update my friends T-Mobile 7T (HD1907) to the most recent generic ROM. She's leaving the country and has no need or desire to keep the T-Mobile branding, and getting on a generic ROM seems like it will allow for faster updates.
I've seen some threads that look like they might help, but having had issues in the past with other attempts on other phones, I know that one little oversight can cause HOURS of frustration.
So I figured I'd ask first and try to save the drama this time.
Where can I get the correct ROM to do what I want on this phone?
I have TWRP installed and have rooted with Magisk.
Current build # is 10.0.3 HD63CB
Carrier configuration version is 2.370001
I appreciate any help on this, thanks!

[CLOSED] T-Mobile 7T Conversion to International WITHOUT unlocked bootloader/SIM unlock!
Here is a patched MSM download tool for TMobile OP7T. It will bypass the need to sim unlock before unlocking the bootloader, and will also bypass the need of an unlock token file from OnePlus (hence skip the wait period of 1 week to get the...
forum.xda-developers.com
The key is to force reboot into bootloader mode when u get stuck on pink T-Mobile bootscreen after first "flash-all" script so u can repeat this "flash-all" second try which will then work.
Thanks for that. I managed to unlock the bootloader and update to Oxygen OS 11.0.7.1.HD65AA, which I believe is the most recent global ROM.
The model of the phone still shows HD1907, which I thought should change from the T-Mobile model to the global model in this process, but perhaps this is normal.
Everything seems to be working fine, but I'm a bit concerned it won't update properly if its not entirely "converted" to the global model.
I did the same. All working fine though. It brought me unlocked bootloader to flash the dual sim firmware or global. All works. Only concern I have is ..The unlock bootloader ticker in dev options shows greyed out "Already Unlocked" but, the ticker is in the off position to the left which is odd. My friends was done by token but mine using patched boot msm. Any reason to be concerned ? Perhaps that's going to hinder the re lock and possible re unlock ?
Some quick tips what I did to my new OP9 Pro Tmob LE2127 on CE22 firmware here in Canada! Picked the phone up a few days ago and loved it right away but hated all the Tmob crap they installed. Tried converting with the Fastboot method and managed to brick the phone as I'm running Linux and its a little more tricky if your not a Linux pro! It unbricked very easily with the MSM back to Tmob tool and an old laptop on Windoz 10. Make sure setup the HUSB Qualcomm drivers properly! Than some reading and realized you can only go from TMob to EU rom with the MSM tool. Tried that worked perfectly the first time did all the subsequent OTA updates all the way to the current Oxygen OS 13 & Android 13 and its working perfectly. At first there were some weird SIM modem dropping and data issues but as I upgraded to newer versions of Oxygen it cleared it self up. Still says two sims in the mobile network area but identifies them correctly also the phone identifies as a LE2123 now! I also didnt unlock my bootloader but I did get an unlock.bin just incase that process took only overnight, I submitted and recieved the Unlock Bin the next morning it shows up in your One Plus account and you download it! Hope that helps some one out and issues I will report back! Phone is very smooth now!

I'm on the fence about that right now the phone is running really smooth and fast I will give it a few days see how it goes!
I received (another and hopefully final) my op9pro the other day. Powered it up and noticed the OEM unlock was in blue and it still is after updating to the latest version. T-Mobile is giving me a hard time on getting my SIM unlocked. Probably because I bought it from Amazon. Want to attempt but I have seemed to have forgotten if root is still achievable with Sim being locked. Sorry been away for a year, you know iphone things.(throws up in mouth). Good phones though for battery life
If anyone has a locked sim,converted and rooted,please do tell if it is possible I don't need the steps,just confirmation that it works. Thanks

It's 100% sure, possible. I immediately converted my 9pro to Eu on day 1, while sim locked. I bypassed the toggle with a tool in the forum but there's also an adb command available for making the oem unlock toggle work.
This includes root and unlocked bootloader while sim locked.
The thing to be aware of is, the T-Mobile variants have a different bootloader unlock process vs non carrier variants. You submit an unlock token to OnePlus and get an unlock bin back, then flash that bin. Lately, people have been reporting the site is broken and they're using support email/chat to submit and get the token. However, this different process can also be bypassed:
Right after you do the Tmo->Eu msm conversion, it's advised to unlock the bootloader on Android 11. Android 11 on Eu will not need the unlock.bin to unlock the bootloader. But it is needed for later versions so if you want bootloader unlocked, do it right after conversion while still on A11.
The "problem" is, once you do this, if you want to sim unlock the phone later, you have to go back to stock Tmo firmware with the stock Tmo MSM tool, as the built in unlocker is not in Eu or other variants. Which means you will have to wipe data later whenever you want to get it unlocked.
it took me 6 Agents at Tmo chat support to finally get the unlock handled properly. One agent asked me to submit my proof of purchase and I did but they couldn't figure out how to unlock it because of the imei starting with 99 and they only know how to unlock imei starting with 35. Thankfully someone else did know how and they got it sorted after a week or so. Some agents told me it needs to be on the network for 40 days, some said they can't do it because I didn't buy it from T-Mobile, some said I need to wait longer. None were true. I told them I'm a developer and needed to unlock my bootloader to test things for my job.
Here's a link to the tool I used for making the oem unlock toggle work despite sim lock: https://forum.xda-developers.com/t/...ader-unlock-enabler-engineer-decrypt.4380419/

I'm sure its possible. If someone wants to get you up and running. But honestly, it's better to learn it yourself in case something happens and you end up without a phone cause you didn't want to learn. It seems rough but once you get it you're golden bro. Tough it out and smash them wires in the phone/computer, and open a terminal and tap away at the keyboard. If all else fails, slap the phone and)or computer around and show em who's boss
I personally had to go to AA as BA/EU was giving me a nightmare of a time with data
Just an update on my 2127 Tmob to 2123 EU conversion! Its working flawless guys I didnt bother unlocking the bootloader when I did the conversion even though I do have the unlock bin. It only took overnight to get the unlock bin this was a few weeks ago! The phone now is working really good everything is flawless still on a locked boot loader which is fine its working smooth and taking updates another OTA update came today! Running A13 Oos 13 LE2123_11_F74.
Which version of MSM tool is best for this conversion?

Yes everything is working good!
Question:
1.Enabling dual sim will add another IMEI to the device, so the original IMEI is duplicated or you get a new IMEI for it? In my country duplicate IMEI's aren't allowed hence asking
2. I remember there was a dual sim patch for OP8T and there were rumors of losing dual sim capability after update is that the same here?
