About a week ago I received notification to update to ICS. After downloading the file and the phone upgrading it get locked into a boot loop, then after about 14 hours it finally escapes form the loop and starts up only to have the SIM not get recognized, I tried restoring to factory default but it didn't work... I then sent the phone to Bell to get repaired but now they are asking for $200 to fix the phone as apparently the bootloader was unlocked and voided warranty.
As you can guess I'm saying "screw you" to that and trying to fix myself... I'm not experienced with android and when I originally upgraded I didn't back up my original software so i have nothing to restore... So basically right now I am wondering what I should do... the phone is being returned to me not repaired and I want to fix this but don't have the knowledge how to... I'm not dumb when it comes to unlocking phones as I used to unlock old Nokia's and jailbreak iPhones but I have no idea when it comes to Androids.
I'm guessing I will need to try and find an official ROM for this but Bell canada isn't the most open with their OEM software so I was wondering if anyone could help in this area by providing a ROM I could use... secondly I guess I will need to S-off my device in order to install the software?
I have searched the forum to find somethings that may be relevant to what I'm trying to do... but I'm getting confused as to what i should do (The curse of being a Noob)
Any info would be great... thanks

Quick summary: you have to be totally stock (relocked bootloader, unrooted, S-ON) to run the update to ICS via Bell.
Thanks... will give it a look through and see if I can recover this way.
Hi i will be receiving a Samsung galaxy s5 in the post tomorrow it will be locked to the network o2. I have heard that if the phone is updated to the latest firmware it will not be able to be updated. So i thought i just wont update it out of the box then and will leave it with the factory update the phone will be the latest model also. I have unlocked phones to networks before but never one of these i have looked through these forums for a decent guide but cant seem to find one. If somebody could point me in the direction of how to root the phone " the rom file and ect" and then a guide how to unlock the phone after it is rooted i would really appreciate it thanks
Hi guys,
I need some clarification re: carrier unlocking and how it works. I recently purchased a carrier unlocked G920T, and I was going to start messing with custom roms/kernels and other goodies. My question is: Will the phone revert back to being locked if I do a factory reset or if I unlock the bootloader and flash custom roms?
I'm not a T-Mobile user, so I can't get another unlock code from them.
Thanks!!
The G920T has a carrier unlocked version, which is probably the one you have, not the T-Mobile one. Even if it is, usually a carrier unlocked device will remain unlocked forever unless it was unlocked using a different or hacky method, then there is a possibility that it will relock

Yeahh go ahead, mess with it. when it is carrier unlocked, the software doesn't affect it, unless it is a hacky method like @serio22 said, but there isnt such hacky method for the GS6 so have fun.
If it is a G920T (the T means it's from T-Mobile), then carrier unlocking is not a guaranteed state. I paid T-Mobile the full price to get my GS6 and they "permanently" unlocked it. Then after a OTA software patch all of a sudden it locked itself again and I couldn't use my phone for 2 days while they tried to unlock it. T-Mobile's new device unlocking uses a new system which has the phone "phone home" to their servers to check if you're allowed to use it outside of their network. It happened again when I accepted the Android 5.1.1 OTA. So...beware of T-Mobile's not-very-permanent permanent carrier unlocking.
I am living in india..
My relatives brought me the t model ( i wanted f model instead of i sold in india for quicker updates but got t model...lol )
Anyways,
The moment i inserted my sim, it worked like a charm so its unlocked at the moment.
I dont know how they made payment their or how it was unlocked, but the way used must be legit coz its still stock at the moment without root / recovery etc. .
I read humo saying it can get locked again...
My main question, what are the odds of that happening?
Also since i live in india, i wont be able to contact t mobile via phone/walk in, are there ways i can get it unlocked again?
I dont have the bill too if it matters
i believe they have an app that unlock ur device since that is how i unlocked mine. if not u can try to contact customer service online since u r not in US.
With device unlock app , will i have to pay for unlock my s6 g920t or it'll unlock my device for free.
I have an unlocked s6 tmobile from usa, i heard the flashing stock rom will relock the device.
If the phone will relock then how can i unlock it again?
I'm not sure about flashing a stock ROM relocking the device. Mine re-locked when T-Mobile sent Android security patches. This week I did the Android 6.0 OTA update and it has remained unlocked.
Hey guys! i have a factory unlocked version of s6 tmobile, my question is if i can flash the tmobile MM firmware . My model says "country: cellular south" and the firmware country says us tmobile, so i dont know if i can flash without any problems, (Sorry for my english it sucks) thanks !

Code:
SW REV. CHECK FAIL DEVICE: 5 BINARY: 3

You can't downgrade your bootloader so you'd have to pay to unlock it unfortunately

Got it done remotely!
I have a Galaxy S6 (SM-G920T) from T-Mobile. It was locked. But it has an "Unlock" app installed by default. I used it and phone was instantly unlocked! Fast, easy and free!
I used to live in the US for a year and bought a g920T. Since i had the requirements i Unlocked and came back to my country but because of a problem, I had to install a stock firmware and now the unlock is gone.
So i'm wondering, if someone with a unlocked phone made firmware backup, remove the IMEI, and send it online would it work? I mean, right now it works just fine, so i can backup my IMEI and ID and just restore it if needed.
Please help

Heya,
I just recently got a hold of this tablet a few days ago and looked for a OEM unlock switch, which obviously wasn't there, both because it's a Verizon variant, and because it's a snapdragon variant. I've been researching for awhile and found combo files to unlock the OEM switch for this model, but everybody seems to get this model confused for some reason. I tried flashing one using odin and got a SW REV check failed [Boot]Fused 2 > Binary 1. I'm guessing I need to downgrade this tablet back down to android 8 since I updated it to android 9. Before I do that, I want to see if flashing the old firmware will be a waste of time or not and to see if there is a combo file or ENG boot file I can flash to get OEM or at least root unlocked. Something to get rid of all this Verizon bloatware and get rid of the Verizon boot animation with just a stock one. Hope I get a decently fast response.

theres not really any support for that tablet.. u can flash combo but so ur aware its not possible to downgrade.. u need a newer combo firmware that is same rev as the firmware ur on..
there is no eng firmware from what i can tell.
I've found several sites that have the firmware I need, but they're all locked behind a paywall. They're only like, $3 but I don't feel like entering my card info on these sites. Might just bite the bullet and get me a throwaway card. My baseband version is T387VVRU2BTB2. REV0.4. maybe somebody can find one for free out there. If not, I'll probably just pay the $3 and stop being stingy with my money.

I'm also looking for some firmware to possibly bypass FRP on my SM-T387V. Did you end up fbuying the firmware? Did it work?
I have a sm-t307u and while not the same device I'm unable to flash combo files due to a new token security measure. So, no OEM Unlock, no bootloader unlock, and no combo flashing in ODIN.
Sorry to just drop a question, but I can't find the answer. Can the snapdragon S10 SM-G973u1 bootloader be unlocked? If not is there another way to root it?
Thank you
Chris
HelloChris333333, just when you post on a forum the courtesy of saying hello. Yes you can root just with the firmware of your model S10 SM-G973U1 US model so not compatible with EU firmware.

I'm not sure that's true, but I would love to find out I'm wrong.
In my research, the SD phones cannot be unlocked unless you are on (and remain on) an older BL version. The last unlockable BL version was 4, as I recall... if you're running updated firmware you are likely on BL 6. Even on 4, the process was not free and once you did it you could not update to a newer version of FW without losing the unlock.
For this reason, I gave up on getting root/BLunlock on my phone... and honestly, I have not missed it. This is also why I have not seen much development of FW for the SD phones anywhere.
Again, if I'm wrong, I'd love to learn how it's done!
Hello meric57
Can you share a link to the firmware I need? I just bought this phone and there is no OEM unlock option, it is a US phone. If I cannot root it I will have to sell it and get another phone.
Thanks
Chris
I guess another question would be where can I get a S10 with the Exynos chip?
Thanks
Chris
Using ADB I keep getting "waiting for device" and then I find I need to unlock the bootloader. This crap is an endless circle.
U4 can be unlocked before , I can unlock it , Special engineering documents need to be made
I'm V6 nothing available. I bought a G973F instead. G973u1 going on ebay.
Exactly, there is really no root/unlock for snapdragon phones unless you're on a very old BL (and you have to stay there so you can't update). IMO, that's not "can be unlocked" even with "special" steps, particularly since most phones today will have newer BLs (even a year ago, I couldn't find a BL4 phone)... but, yes, it's technically true to say it can be unlocked, but only in very limited cases.
@Chris33333 For this reason, I get that you may want to go to the Exynos instead... I'm curious, if you're in the US, how does that work with carriers? Does it? I've found most US carriers refuse to activate phones that don't match their list of "compatible" IMEIs... I imagine an F-series phone won't be on that list.
I'm in the US using Straight Talk with T-mobile. I've had a Galaxy S5 rooted for years. With straight talk I can use AT&T, T-mobile, or Verizon. But this international phone does not do Verizon.
And StraightTalk will activate the F-series phone without complaint or issues? If so, that's great to hear... because I know VZ and ATT typically won't...
I haven't put the SIM in it yet. Still trying to delete all the crap off the phone.
Lol
