[Q] GSM Unlocked - Need Help with something silly...? - T-Mobile Samsung Galaxy S6 Edge

Hey All!
I finally got T-Mobile to do a full carrier unlock on my device. It is not paid off, it is just 2 days out of the box. There is a long story that goes with it, which I'd be happy to provide. I do want some help though before I go through it, if you would please assist.
Before they unlocked the device; I had installed TWRP, custom kernel, and AllianceROM. Fortunately, I backed up my original stock ROM with Ktoonz kernel before flashing Alliance. The T-Mobile Unlock app does not work on AllianceROM for probably obvious reasons. ANYWHO...I flashed back to my backup, ran the unlock with them over the phone and done.
Am I safe to flash back to AllianceROM backup I made? My understanding is once unlocked, forever unlocked. I would hate to flash into my previous backup to only lose my carrier perma unlock.
Thanks for the help!!!!

Once its unlocked, it's unlocked. It makes no difference what Rom you install afterwards.

Pretty much the exact same thing with me 2 days out of the box and not paid off or even used on the network. I did wait to flash recovery and what not till it was unlocked once it is perm unlocked though you are good to go I have flashed numerous roms and flashed via odin, and even had to use smart switch recovery by serial and still unlocked.

I went ahead and did a full back up of my unlock. Went ahead and flashed the ROM fresh over, not the backup, and reflashed the kernel. Still unlocked and good to go. Did it all through TWRP and no problems. Glad it didn't remove the unlock because I can't imagine continuing the battle! At least it is working perfectly with AT&T and has a full carrier perma unlock, rootable and bootloader unlock

Then you were not fully unlocked. You need to flash back to stock and call T-Mobile. Unlock app does come back after restore but it does not relock the device. It may say failed if you try to use it again as it is no longer in there system but unlock will stay.

[Q] R800a can not OTA update or enter fastboot, root problems? mode.

I recently purchased a R800 from someone on Craigslist. The phone is already rooted, permanantly I think since it is rooted after doing a factory restore. It is not sim locked, I believe its factory unlocked.
I tried to do the OTA update, which downloads, but fails to install. It appears to get about 3/4 of the way done, reboots and gives me an "update failed" message.
I wanted to unlock the boot loader, I got the unlock key from SE. I must of tried 10 times to get the phone to boot into fastboot mode, it NEVER does it. It simply boots up normally. I even got an app that makes it easy to reboot into restore or fastboot modes (just click an option and it reboots), however just like before the phone simply reboots normally. I even did a factory restore prior to trying the update... no go.
Should I try to remove the root access? Is this what is giving me all the problems. I was able to successfully install root explorer and titanium backup and both of those programs worked fine.
R800i, Android 2.3.3, Kernel 2.6.32.9-perf [email protected] #1, Build number 3.0.1.A.0.145
Edit: Title should be "Can not OTA or enter fastboot mode, root problems?"
Is your phone sim locked? Sim locked phones need to be unlocked before able to unlock bootloader or fast load. After you unlock bootloader make sure you never ota update.

Your phone has a locked bootloader and a factory lockout on fastboot.
Best advice to you is flash the r800a world generic 2.3.2 root it with gingerbreak then ota update. Use a program called wontanserver as its super easy.
Dont get anyone to remove your factory locks on fastboot until you read tons of threads on these fourms from the last couple months.
Ok, lets see....

My phone is the R800a. It was my understanding that this phone was never locked (factory unlocked). It came in an official Sony Ericsson box and has no carrier branding on it what-so-ever. It was not purchased through a carrier. It does have a weird stock data APN called "Telekila"?!?!?

Doesn't wontonserver require credits to run? How expensive does this get?
I didn't know the phone could have a factory lock on the bootloader. I did go to the SE website where you get the unlock key and it was successful in giving me a key... Well I shouldn't exactly say "successful", it did give me a key code to use if and when I can unlock the bootloader, weather or not that code is actually legit remains to be seen. I'm a bit skeptical now since you said the phone is bootloader locked from the factory. I though SE was allowing their phones to be unlocked. I recently unlocked my Motorola Atrix and was expecting to do the same with this phone.
Thank you guys for the advice. I love this phone so far but I can't wait to get a custom rom on it
It uses credits but they are free.
There are currently 2 gentlemen on these forums that can remove your fastboot locks and unlock your bootloader.
Have a look for thier threads on this matter
I would like to have this done now, so gentlemen, whomever is able to do this please message me and we can work something out. Im dieing to get a new rom on this awesome phone/game console.

If you need help with unlocking your phone contact Alejandrissimo he does Unlocks
I flashed the r800a world generic 2.3.2 rooted it with gingerbreak then ota updated.I get the same thing as DMpire , reboots and gives me an "update failed" message.
Is this because I removed some of the stock apps that came on the phone after it was rooted? Anyone know about this?
Does it matter if the SD card is mounted or not?
Removing stock apps then trying to ota isnt going to happen. Reflash, root, ota, then remove your stock apps
Is there any easy way to do this? can I reflash it as it has a locked bootloader, or do I have to get the bootloader unlocked?

I can't tell if my phone is unlocked or not?

Ok, my phone was unlocked and rooted. I did the update for Verizon a while back. Lost root, but i'm not sure if I lost unlock. I'm getting a replacement from VZW and what makes me think that it is still unlocked is a padlock that is nearly locked but not all the way. This is on the black screen with Google above it, and not latter where you can slide it.
I did try searching, but I couldn't find something like this.
So, if it is unlocked I would follow this, right?:
http://forum.xda-developers.com/showthread.php?t=1392310
and scroll to: Q. I want to send my phone back so I need to flash a stock rom and relock the bootloader?
Thank you!
Edit: Found a pic: http://mainframereview.com/newsite/wp-content/uploads/2012/05/samsung-galaxy-nexus-review-zach4.jpg
Seems like the bootloader is unlocked, but it is not rooted. Btw root checker is telling me that it is unrooted also my wi-fi tether doesn't work any more. So, the guide above should work right?
Yes. It's unlocked or you wouldn't see the lock. Yes, before you send it back flash stock and relock.

Flash new ROM to unlocked phone

Good Day
Sorry if this question was asked before, I am not clear about flashing new ROM.
I have a locked GN3 from tmobile, I bought unlocked code from eBay and my phone now working perfect with international career.
If I flash new ROM 4.3 or 4.4, will it be locked again? if tmobile release new update KitKat 4.4, should I update? re locked?
Thanks
Flashing any rom will not lock ur bootloader. Once u unlocked ur boot loader, unless u lock it back. It will not be locked by flashing roms etc

OP...I used Chainfire's RegionLock Away App on my rooted T-Mobile Note 3 and had to Odin back to stock for some troubleshooting and it was still sim unlocked. Once you sim unlock it once you should be good to go from there on out.

He's not talking about his bootloader, he's talking about the phone being sim locked to T-Mobile's network.

Rooting Unlocked Phone Question

I have an ATT phone currently unlocked and using it on T-Mobile. I want to root and use it on T-Mobile, but Im a little nervous that once I root, and wipe everything, the phone will be re-locked to ATT. So my question is, once I root will I lose my carrier un-lock?
It might be helpful to clarify a couple of things. It sounds like you're currently SIM-unlocked (thus able to use your AT&T branded M9 on T-Mobile). Are you currently bootloader-locked and want to unlock it so you can root? Or are you already bootloader unlocked?
Rooting definitely does not wipe/re-lock anything. Unlocking your bootloader triggers a system wipe. My understanding is that once your phone is SIM-unlocked, system wipes don't affect your phone's SIM status.
Sorry for the confusion. I am currently sim unlocked, and I want to bootloader unlock. However, before I unlock my bootloader, I want to make sure that I wont re lock my sim. My ultimate goal is to unlock bootloader in order to root, but I dont want to relock my carrier to ATT. Yes, it is an ATT phone and I'm using it on T-Mobile.
I'm pretty sure that unlocking the boot loader will not affect your SIM-unlocked status.
But if it were me, I would want a more definitive answer than that.
Another forum member may be able to answer for sure. In the meantime, consider asking HTC directly via their chat system. I've found them friendly and straightforward.

No you won't lose your unlocked network status.
The unlock once done is permanent.
There was one a while ago on the s3, an app, which was unofficial and I lost that a few times between flashes, but I don't think you'll have that issue.
Thank You. Unlocked boot loader, rooted and still have sim-unlock.

Downgrade back to Pie

I am on the official Android 10 firmware and would like to downgrade back to Pie. Is this possible without unlocking the bootloader? The T-Mobile unlock app apparently don't work on 10 yet so I need to get back to Pie to unlock then I can go back to 10.
Yes, I think you can. You can sideload an OTA image without unlocking the bootloader. Even though it says OTA, it is a full factory image. The files and directions are both available at that link. If possible, I would certainly do a full factory reset of your phone as soon as it booted however. You never want to back into an older version of Android without doing a full factory reset.

Ok, I just tried that and part way through installation it aborted. "E:Failed to verify package compatibility" along with some other errors...
To revert to pie you have to use the full image and the platform tools available over at Goog but for this you need to unlock the bootloader. If you want to stay on a locked bootloader you then lock it after you're up on stock pie again. Keep in mind you'll want to do the works before you move any data back to the phone and that unlocking the bootloader will wipe the phone so you'll need to back up everything before you unlock.There are specific instructions for all of that and the images and tools at https://developers.google.com/android/images
Don't be afraid of unlocking the bootloader, it can be unlocked and locked again at your whim over and over. Doesn't hurt anything other than you get a wipe in the process.

I cant unlock the boot loader because the phone is SIM locked to T-Mobile. This is the whole reason I want to go back to Pie so the unlock app will work. This sucks
You can get it sim unlocked by phone if you meet their unlock requirements, or at least you used to be able to do so, I did it that way there myself a few years ago. If that's not the case anymore then... yeah, you're in a pretty sucky spot.

I do meet their unlock requirements..They have a ticket open with engineering for over a week but I’ve found out from other means that the unlock app isn’t compatible with Android 10.
Do you mean there’s another way to SIM unlock then the app? If so please enlighten me.
"You can get it sim unlocked by phone..." You call them on the good old fashioned telephone and tell them you want to remove the sim lock. Customer service can do it without the app, to my knowledge this was possible as recently as the 6T; Tmo guys were calling up and getting it done in essentially the same scenario you're in.
