[Q] Short question about the bootloader

Hi guys!
I'm about to buy a Nexus One on Ebay but I have a short question to you guys
Since the seller has unlocked the bootloader to install custom ROMs, he restored the phone's recovery and OS to stock Google's stuff.
My question is: when Google will release 2.3 ( Gingerbread ) OTA update, is my phone going to get it like anyone else if my bootloader is unlocked?
I would really appreciate your help guys!
Thanks a lot!

Unlocked bootloader will not effect the phones ability to receive and install OTAs.

Are you sure my friend? I really want to be sure about receiving official OTA updates
Also, is it possible to lock the bootloader like if it was a brand new phone?
Thanks again guys!

I'm 100% certain.
My bootloader has been unlocked for quite a while, and yet recently I returned to an older stock image and received an OTA update as soon as I rebooted...
The bootloader cannot be re-locked, unless you have one of the very few "holiday" versions of the phone...

So when 2.3 Gingerbread will be released as an OTA update, my Nexus One will get it at the same time?

If everything else is stock, yes, you'll be fine. If you do have any problems, you can always come back and deal with them then...
May as well enjoy your phone, and perhaps read some more of the forum while you're waiting for the update?
Welcome aboard! xD

There are people working on relocking the bootloader, but it's likely going to take a while to achieve

yes your phone will get the official update just fine. but i promise you, bet 100 bucks that with that unlocked bootloader, you will download the next update on your own long before google officially pushes it to your phone. you wont be able to wait. unlocked bootloader is the way to go...

[Q] Debrand my Three branded HTC one?

I just got the HTC one on Three and I'd like to know if it's possible to flash the unbranded ROM so that I can get access to the 1.9 update without having to wait for three to push it to me?
Thanks all

I also want this. I am new to Android and after seeing the 3 splashscreen, bloatware and having to wait for the update, I am getting a tad pissed off for not getting a factory unlocked version.
I found the stock ROM, my question is: If I flash it to it, will I be able to use OTA updates directly from HTC and in general will my HTC act like an unbranded one?

I believe that to permit unbranding, that would also allow ota update from HTC rather than ota from your carrier 3 you would need to enable super cid, which cannot be set on an S ON phone.
Majority of HTC phone are supplied with S ON.
So if like most people your phone isn't S OFF then you can't achieve permanent unbranded status.
All is not lost though, if you want a nearly stock version that is the most recent base without waiting for 3 then you can install a custom Rom like ARHD.
I bought my 3 branded phone on 28 March 2013, and within days had unlocked, rooted and Installed ARHD.
Am now on ARHD v8.0 based on the latest software base: 1.29.401.16
The only downside is you have to manually update, that is to say you won't receive ota update .

Hmm thanks for the reply. When you "rebranded" it, did you get it unlock as well? or did you buy a code online?

The procedure I followed is to unlock bootloader via htcdev website. I don't believe This process unlocks your phone to allow a non 3 SIM to be used. I haven't tested this, but believe that carrier unlock requires a different process, I think you can obtain this only via paid unlock that I've read costs about £10 to £15

Ahh thanks! The most important bit for me at the moment to get the splash screen and OTAs (i.e. 2.29) working... I would prefer stock ROM however...

Fantastic! Thank you for the info i'll get onto that tomorrow

[Q] GSM Unlocked/T Mobile Motomaker Firmware

I plan to root my 32 GB Motomaker GSM Unlocked/Tmobile Moto X by downgrading to 4.2.2.
To do that I need the 4.2.2. firmware, but I don't know which firmware to use as I know there is a Tmobile 16GB phone.
Which firmware do I use? Is the firmware labeled TMobile the same as the GSM unlocked?

Good luck and let me know if you have any issues

Stop stop. Don't do that. Just get the unlock code and unlock the boot loader. That way you can root and recover and not mess with exploits that can wreck your phone while the boot loader is locked.
If its unlocked you don't need to jump through those hoops. Simply flash twrp recovery and reboot system and it will install supersu.

he is correct still use this guide but go down to the section about root with a unlocked bootloader. it will get you right threw it a lot easier and faster.

Thing with that is that it voids the warranty since he has the Moto maker version and not the dev

You are right. I don't want to unlock the boot loader because of the warranty issue.
Following the process - although lengthy - will root without voiding the warranty.
-LeeTxJD

Catch 22 then... Because once you go 4.4.2 you won't be able to downgrade anyway. BTW, at least until recently, the phone comes with 4.2.2 and immediately updates to 4.4 so you shouldn't have to downgrade if you want to try all that. Here's the other thing you should know... You have 2 weeks to return of exchange the phone (30 days in California) from the day you got it. You unlock and root and do all that and find an issue you can return it regardless of have it replaced. I know because I had to do that... My moto maker x was also boot loader unlocked and I got my money back.
Its not all that likely you will get something wrong with the phone past the initial period but it's up to you. You are more likely to break the phone trying to root exploit than it breaking past 2 weeks out of warranty.

What if my phone is Developer Edition (GSM) - will I be able to downgrade from 4.4.2 to 4.2.2? I am willing to unlock bootloader and to root.

If you take the OTA to 4.4.2 you get the 30.B4 bootloader. From what I've read, you cannot go back to an earlier bootloader and earlier system versions will brick if attempting to use them with the 30.B4 bootloader. So no, I don't think you can revert to anything earlier if you get to 4.4.2. At least this is my understanding.

[Q] has there been any progress on unlocking the bootloader?

So I just got my note 3 n900A att model about 2 months ago. last month the lollipop update pushed to my phone and I was happy but then I started working on rooting. I successfully downgraded my phone to 4.4.4 then to 4.4.2 by following guids on here and on another webiste that instructed me to use odin and then I rooted. Right now I am on Biggons rom and it is beautiful. I have been using safestrap to flash custom roms for this n900A.
I am however interested in trying to obtain a custom kernal and the bootloader being locked is frustrating. To my peasant understanding there isnt a option as of yet to get around the bootloader. please correct me here if I am wrong.
Are any developers working on this? Is it even possible to work on this? Am I just completed F'ed unless I went out and got a different variant of this phone with an unlocked bootloader?
lastly! Im curious if it is possible to turn my phone into a developer edition? that might be just a repeat version of my previous question. excuse my ignorance. I am new to this phone and boot locks n the what not.

Carrier unlock a G920T permanently

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
Sent from my SM-G920T using Tapatalk

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 !

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
