Help unlocking G920T to Metro PCS.

Hi guys, I have been reading for days but can't seem to find a concise guide. I am trying to use a Metro PCS SIM card in a locked TMobile S6.
I have installed twrp and root through Odin, but I can't manage to download the G920T1 firmware anywhere without it failing and forcing me to pay. I have tried sammobile and others.
After I flash the G920t1 firmware will his metro SIM card just work or do I then have to do a SIM unlock as well? Do I use a TMobile or MetroPCS unlock code if I need to SIM unlock?
Also does anyone know of a ROM that will allow me to use his Metro SIM without any of the above nonsense? I downloaded a ROM but I only have my Verizon SIM to test and it asked for an unlock code.
Any help is appreciated. Thanks in advance!
EDIT: After checking Android file host I found a link to the latest G920t1 firmware. Downloading now in hopes this gets me one step closer. https://www.androidfilehost.com/?fid=24591000424951428

Well I got the Metro PCS software running fine and when following this guide on unlockbase it says I just need this TMobile/MetroPCS unlock code and to put in the new SIM card and it should work.

Will report back later this week after purchasing the unlock code and attempting to input it.

One other note is when booting to stock recovery it warms me of multi csc. Its my understanding that this interferes with OTA updates. Is there anyway to fix the multi csc so my friend can take the metro pcs OTA updates or will I have to manually update them for him each time a new one comes out?

Your best bet is leaving it on tmobile rom.. if it's unlocked it's unlocked the sim will work just fine... just because you're using a different sim doesn't mean you gotta change roms
Leave it on what the device actually is, and let the unlock code make anything work for you
The S6 development is pretty dead and you will only really find updates for ours first, and if it's an original Tmobile device.. keep it on that, it's unlocked to work with anything but you don't have to flash anything specific to it G920T Use tmobile stock rom, unlock it and move on and do your business.. install twrp, get root , maybe a custom kernel and or rom?
If you root and leave stock recovery you're gonna have deep sleep issues, there hasn't been any MAJOR updates in awhile and it's only gonna go slower and slower with our device getting replaced by S7's and Note 7's
Roms will be updated to newer firmware bases, and JUST the bootloader and modem files will be online to quick flash within 2 minutes in odin to be updated then flash a updated rom base to the newer firmware if any future releases come.
Don't know too much about CSC sorry about that, but hopefully I at least get you on the right track?

The phone is locked. TMobile has the SIM unlock from the dialer disabled on the s6 firmware. You have to go through them to get it unlocked which my friend is currently unable to do, due to issues with payment on his account. I checked his imei and it says it's all good so I assume a traditional SIM unlock using the Metro pcs software should work.
I wasn't going to root or install twrp as this friend has no need for either and is fine staying on the stock software.

v21: Root/Unlocked Bootloader + TWRP?

Hi! When I got my R1 HD, I wanted to get Lineage OS and TWRP. I tried everything including:
adb "fastboot oem unlock",
SP Flash Tool, and
DirtyCow R1-HD Tool,
yet I found no luck. Does anybody know how to get an unlocked bootloader and TWRP on an R1 HD v21? Thanks!:good:
P.S:
My "Custom build version" is:
BLU_R0011UU_V21_GENERIC. Also, this is not the Amazon Prime variant, however I got this from Amazon (for example: I get no ads).

Sorry to tell you, but version 21 of the ROM cannot be bootloader unlocked or rooted. The more recent updates have secured the phone so that none of the previous methods you mention work anymore. The phone is no longer being manufactured and Blu does not provide a process for unlocking the bootloader as some other companies, like Motorola, do. So even though you paid more to get the no ad version, you can't root it. 8-( This was only possible in the earlier versions of both the amaon and non-amazon models.

So, can I revert back to an earlier version of the ROM where it is possible to unlock the bootloader?

no, the signed updates are incremental so, the checksum verification will pervent flashing old version

OK.... What's the best thing to do now?
I found this option in my updater that says "Local updates". Maybe this can help?

No, sorry - there is no known way to root or flash modified software after the phone has been upgraded with factory software. You can't go back. And, even if you could, it wouldn't help - it still couldn't be rooted or flash a modified ROM. Blu does not offer to unlock bootloaders the way some companies, like Motorola, do. Your phone is stuck with what you have now.
The best thing to do now? Enjoy your cheap android phone with great performance for the price!

Well, is there at least a way to skin the phone (ex: change bootanimation, remove bloatware (Yes, there is still bloatware apps, and I'm talking REMOVE the apps, no uninstall for user only), remove the Adups spyware) so that it is just like stock Android?

No - all those things require root, which you can't get. Only the phones that were shipped with earlier versions of the ROM and hadn't been updated over-the-air could be unlocked and rooted.

Related. I have an 8GB phone; Custom build:
BLU_R0010UU_V8.7_GENERIC 05-08-2017
I've been trying to install TWRP (and then Lineage) but I'm having zero luck with SPFlash. I've tried on a couple of computers and followed the directions step by step. Am I missing something here?
Thanks,
Edit: yep, saw in another thread anything above 8.1.
Imma email Blu and see if they'll loosen the restrictions if they're stopping development. Can't hurt at this point.

Samsung Galaxy Tab A 10.1 SM-T510 - How to unlock KNOX

Hi everyone..
Bought a Samsung Galaxy Tab A 10.1 SM-T510 online... I believe that this tablet is from an Online News Subscription. The previous owner decided not to renew the contract and the devices got locked.
Is there any way for me to re-use this device? any way to bypass the lock of re-set it. thanks...

I don't know if I could answer your question, but have you read this both comments:
OEM vs Bootloader lock.
The guide to unlocking the bootloader on the newer Samsung tablets seems to cause confunsion about what the OEM Enable switch does. First of all, the OEM switch has no direct bearing on the Bootloader lock. That switch has been around for quite...
forum.xda-developers.com
anyway, if you're able to get it running, be aware to *NOT* update the Tab to the lastest stock rom (5BUC4)
cause your are then unable to flash stock rom lower the 5 what is sometimes needed to flash custom rom's based on 4.

The previous (and current) owner of the device, is the Online News co. The subscriber that was using the device was merely "renting" it. I doubt seriously if you can find a way to bypass their lock without their permission. It probably has a proprietary bootloader, just like a phone that is locked by the carrier.

is there any way to flash a custom ROM that will reset / remove the lock?

No. In order to flash anything, you have to enable Developer Mode. And if you can't get past the lock, you can't enable it.

I would try to get in contact with company of the News Subscription and/or the lastest owner of the device.
if the company is able to lock the device, they're able to unlock it.
maybe another way (maybe !):
I would try to flash @Magendanz TWRP recovery and then format the partition.
I'm no expert, but I doubt that there is an additionally lock on top of Samsung, google, ..., what-so-ever .
I guess the lock is in software somewhere, but you gave to few info's of your device, e.g. what you're able to do and what not.
Why I'm thinking TWRP is installable (if the requirements for this are fullfilled !):
I mistakenly flashed the lastest FW with binary version 5.
All my attempts to flash a custom rom where denied cause a downgrade of the bootloaders binary from 5 to 4 was involved.
But I was able to flash the above TWRP and could format partitions and more.
Obviously the bootloader wasn't touched doing so...
and with TWRP installed I was able to flash CaOS.
Obviously it doesn't care what stock binary version was installed.
Have you already read all the stuff regarding "unlock" and such ???
are you able to get Developer Mode ???

Question Can the latest leak of the full international ROM be safely flashed on an NE2217 (T-Mobile)?

I've been wanting to convert to international for a while now but I heard it's very risky, I'm curious if anyone has an answer as to whether this is safe to flash since it's a full ROM

On page 2 there's a thread that should answer your questions.

Ok... Honest opinion... NO. If you are NOT sim unlocked and NOT bootloader unlocked, then when you flash to Android 13, your device will become locked completely... As in no apps will open and you will get some stupid "Contract Phone" error no matter what you tap. I'm trying to hunt down the process that activates this but it's hard considering that the only time it triggers is when you pop a TMobile sim into any other A13 firmware other than the original TMO flash. I know that they TECHNICALLY are the same model, 2217 ... 2217.... And myself am sitting here using 2215 FW on my 2217 TMobile locked phone... But I went thru nightmares and hard bricks to get mine working. I took my phone down to completely unresponsive state.... Had it revived to 2217fw, but NOT the TMO branded....and then used FB to get my unlock token for the bootloader. Once BL unlocked , I tried updating to the same 2217 android 13, and the phone did what I said earlier.... But thankfully I had FB and unlocked BL, so I just flashed the stock recovery and stock boot.img and it went back to working but on Android 13 (with A12 recovery and Boot.img). I don't recommend that at all because while yes I have had no problems doing it to several other phones with no bricks... I have had several reports that ppl didn't get the same success.... As of today I have flashed 27 ne2217 phones to 2215 then 2217. But I have had some headaches with using the exact same processes every time but getting different outcomes every time. There's SOME FILE that needs to be disabled in the system so this can be done safely, but unless you are Sim Unlocked and BL unlocked I cannot recommend you attempt this. That is the only factor I think that has made all my flashes successful, cuz ultimately it's a TMobile BRAND lock... Not region... Cuz ne2217 is NA... So the region is the same as I'm in Texas... But if it's not TMO branded fw.. the phone freaks out sometimes. But only with android 13. Kinda like how the 'Orange' state came back with the updates.... TMobile did this on purpose probably because of all the posts here about successful region swaps! Be warned! The TMO Mafia is waiting to put a brick in your hands!

Question Help, i did something stupid.

Hello
Hoping somebody can help getting my phone up and running again.
I wanted to unroot my phone, because i was having issues with danish "MitId". And was a bit sloppy with it.
First i tried using SuperSU to remove root. Because i didnt feel like setting everything up again. Didnt work.
Then I locked the OEM Lock in developer settings. Not thinking this would be a fatal error.
Got home from work, and said to myself. Jusk lock the bootloader and the phone will reset itself.
But this is not the case, when you have been stupid enough to lock the OEM lock.
Now I am stuck on "No valid operating system could be found. The device will not boot"
I can get in to fastboot by pushning power+vol down. But cannot flash anything since the phone thinks the OEM Lock is locked on it.
Does anyone know of a solution for me. Or is it going to the shop tommorow and say that my phone is going this. And hope they will sort it for me?

Can't you fix stuff by using https://flash.android.com/ ?

No, unfortuantly not. It fails:
Device Unlock Disabled​For security reasons, you need to enable "OEM unlocking" in order to flash your device. See the device preparation instructions for more information.

Try sideloading the full OTA. You don't need an unlocked bootloader for that.

Unfortuatly not, if I try to enter recovery mode. The phone just goes back to the screen saying "No valid operating system could be found. The device will not boot"
ADB is not available to me

If you can't sideload the OTA, I'm afraid there is not much else you can do with a locked bootloader except try to RMA it.

Can you get into recovery at all. Even if it's the stock you can attempt a sideload of the stock OTA.zip from Google. You may also try if your on boot slot A
fastboot --set-active=b
On b use
fastboot --set-active=a
Try to see if the other boot slot has an a bootable OS.
*****I apologize I just saw it's actually still locked****"
Contact U-break I-fix if I typed that correctly. The third party warranty repair center for Google's warranty. I believe they can attempt to switch the boot slot with a locked bootloader with the equipment they use to reflash these devices. If anything it's under warranty get the RMA and if the bootloader is locked on it trade someone or sell it and use it to make buying a new cheaper..

No, I can get into fastboot and that is it.
But everything I try in fastboot gets rejected, since it says the phone is locked.

Does the bootloader screen on the phone have the option to boot into Rescue. This has a ADB connection but I am not sure if adb sideload works

Really mad that Google intentionally locks phones this way, turning them into completely functional, but useless piece of junk. I guess that's late stage capitalism for you xD

Google is not responsible for phone's with locked bootloaders. They make the device with the specifications the carrier that sells it stipulates. Google themselves allows the unlock.

Iam guessing the same. Phone doesnt want to do anything.
And since i cant get into the phone to oem lock i am stuck. Live in Denmark, so by law I havnt voided the warrenty by rooting.

Pixel warranty is always valid even if you unlock and root. Google doesn't void the warranty. Go to Google pixel support page. Find warranty and act as if your submitting a RMA and it will tell you after you enter the device IMEI how long your warranty is valid for

Delete

If that were true. Android flash tool https://flash.android.com/welcome
Would work as it's the same process for the browser to flash the very same file. Motorola allowed signed factory img on locked. Google had never allowed that in fastboot as far as I am aware

DroidRommer said:
All you need to do is go here Factory pixel firmwares and scroll down to pixel 7 panther assuming you're not on the pro (cheetah)
-select the latest version for your model whether that's Verizon or whatever if you have the carrier unlocked one like myself just choose the Feb firmware that doesn't have a carrier name at the end of the firmware number (you should have your phone plugged into your PC and in fastboot mode) click flash and follow the steps. These are Googles factory images so it doesn't matter if your bootloader is unlocked or not as long as you choose the latest version and the correct version for your phone. Tbh you can't really brick the pixel 7 as long as you have a PC and are able to put the phone in fastboot mode (holding the volume down and power button while powering on)
-Anytime you run into some kind of bootloop issue or wanna get rid of root flashing the stock firmware from this website will factory reset and revert your phone to the way it was the very first time it was pulled out of the box and powered on. If you have already tried this and you know forsure you did everything correctly then I must admit I have never had this happen and I'm someone who flashes custom roms and goes back to stock to get the latest security update just to turn around and flash another custom rom right after lol. If you need any help or advice feel free to pm me whenever. I have been rooting phones for a long time and have to say that the Google pixel is by far the most user friendly phone I've ever owned when it comes to custom rooms, rooting etc. You can ALWAYS go back as long as you know what steps to take. Sorry for the rant especially if you already figured it out.
Happy Customizing!

Their bootloader is locked. You cannot flash a factory image like that with a locked bootloader. They also turned off OEM Unlocking in the developer settings. If they had left this enabled they would be able to use Android Flash Tool as that tool will unlock your bootloader if OEM Unlocking is enabled.

This wouldn't be Google, they basically encourage you too unlock the bootloader and root if you want as they give you all the tools you need and factory firmware options to go back if you make a mistake. Tbh if you are able to unlock and root the phone to start then you can go back. Even with a locked bootloader you can always flash the latest factory image on googles dev website, you just can't downgrade firmware or install different carrier firmware without the unlocked bootloader. If we really wanna poke at some phone developers I vote Samsung as I have had multiple people ask me to root their phones and if it's a US snapdragon version it cannot be done its so frustrating lol thanks for letting me vent, have a great day if you have the the carrier unlocked dev edition of the pixel 7 and ever need any help feel free to pm me. I have been rooting and romming pixels for a long time
Edit: I was not aware you couldn't flash the stock firmare using googles dev page without oem unlock. I apologize for jumping to conclusions. I thought I had every possible bad scenario happen to me by now but apparently I learned something new today.

Dude. You cannot flash factory images of any kind on any Google phone with the bootloader in locked status. Please stop giving false information on here. If you want to talk up Samsung do it on a Samsung post. Let's not confuse everyone please

To use Android Flash Tool, you have to have OEM Unlocking enabled in Developer Options for it to be able to unlock the bootloader.
To flash the factory image in fastboot you must have an unlocked bootloader.

Okay my bad you are right fortunately I have never had this happen. And like someone else said if he can't get into recovery then he can't sideload a factory ota... sorry I'm at a loss on this one. Some custom roms use "fastboot update file.zip" would that do anything in this case or would that command not even work with a locked bootloader I'm assuming. I apologize for trying to act like a know it all I've just never heard of this happening
