Samsung :: Galaxy S - Locked Bootloader?
Aug 26, 2010
The whole range not just the bell vibrant. Is the bootloader on these things open? Anyone running froyo on it yet? Or any custom roms? Thinking of getting the TMobile version, but it'd be pretty useless with a locked bootloader

I have purchased a S6 from Amazon, but the device is branded with Swisscom, with an awful boot logo and sound, and a few specific apps. I'm waiting for a nano sim, so for now I don't know if the phone is also simlocked.
I intend anyway to install custom roms, so I don't care much about this, however I can't find out whether the bootloader is locked or not (in which case, I'll have to send it back to Amazon I guess).
The device is a SM-920F, I made the OTA update to 5.1.1 upon powering it. Not sure what the bootloader and rom exact versions are, but I will add them to the post if necessary.

Rooting (or Jailbreaking if you're used to the iPhone) is pretty awesome - it enables you to use a whole bunch of apps that are previously offlimits (such as Titanium Backup - a piece of software that will back up all of your .apks. It also enables you to remove some of the built-in bloat that Sony stuffed onto the Xperia Play which frees up a bit more space for new apps (Who honestly needs the Chinese keyboard on their phone?!)The classic way to root a phone is to first unlock the boatloader and then through that, install a version of your ROM that allows root access. However, although SE are providing a way to unlock the bootloader on a Play, this is not ideal because:Unlocking the bootloader automatically invalidates your warrantyWhen you have unlocked your bootloader, the software update function on your phone stops working as SE consider your phone to be "modified"Most phones are SIM-locked to a particular network and are therefore not even candidates to be bootloader unlocked The solution is to root your phone without unlocking the bootloader. How? A new application called Gingerbreak does it all for you! Literally, all you need to do is download the Gingerbreak .apk, run it and enjoy your new rooted Play. I can confirm that it is 100% working and took about 5 minutes from start to finish.

The world knows updates in a Motorola phone is very slow! This leaves power users with no other option but to go for custom ROMs. Even there locked bootloader is always a very big problem! Moto promised long back to unlock bootloaders. Defy and Defy+ are now quite old phones and will receive no update either! So now is there any hope that the bootloaders will be unlocked? This deters most devs and power users from getting Moto phones inspite of an excellent build quality. Hope we get a reply and this thread don't die without any use!

So I think I know the answer but wanted to validate. If I leave the bootloader locked on my device and download a factory image from Google, cannot I just put the zip on the sdcard storage and run it through recovery to update? I don't think that I need to unlock the bootloader do I? I am trying to keep everything stock for now, but updates are a big reason I wanted this phone. Also don't want to break Android Pay.

My Dad's HTC One M7 is stuck in the bootloader screen and is unable to boot to the main OS.
The phone has never been unlocked or rooted, I've never even seen the bootloader screen until now. The first thing it says in the bootloader screen is ****LOCKED****.
The only information I know is that prior to this, he was prompted for a system update which (he says!) looked official.
I've tried every option in the boot menu (fastboot, bootloader, recovery, recovery reset) and it just goes back to the main screen.
Is there a key combination that I'm missing? Was the system upgrade corrupt? I know next to nothing about Android bootloaders.
I have tried Googling for hours but all the results are from people trying to load a custom ROM or unlocking the bootloader - nothing about a 'normal' installation.

Connected Galaxy S11 to Kies and was informed a Firmware upgrade was available. Current was shown as PDA:KF3/ PHONE:KE7 / CSC:KG2 (O2U) New shown as PDA:KJ1 /PHONE: K14 / CSC :KJ1 (O2U)It started off Ok and downladed firmware. Checked encryption of binary, unpacked binary, changed the picture of computer/phone to grey panel and started downloading to phone. Phone shows gren robot and "Downloading... Do not turn off target". It downloaded 11% and stopped.That was at 1540. It is now 1710 and it still shows 11%?

I am trying to retrieve photos from a Samsung Galaxy S6 that is stock at the lock screen. The finger print scan is not working and they do not know there back up password. I researched two ways to get around this.
1. Entering in the google account user name and password
2. Signing into Find My Mobile with the samsung account information and unlocking the phone
If both of these options fail due to the owner not remembering there above credentials is there any other way to retrieve photos. How about putting the phone in dfu mode and using a program on a computer to copy photos from the internal storage. Is something like this possible?

I often find myself waking out with a locked up phone. I use fingerprint and no matter how many times I reset my alternative password, it somehow magically changes and I cannot 'remember' it.
I used to lock my phone with android devide manager to fix this but now when i try to do so it says ''Since Google has confirmed that the screen lock is already set, entered password will not be required '' and now i cannot unlock my phone by entering a new password. I dont' want to do a factory reset, what is up with this?????
I really do not want to lose any of my data.

I have been trying to unlock it for use in Italy, but I can't get past the initial setup which is asking for my original Samsung login ID, which I obviously don't have. In addition, I can't flash the rom with Odin or install off of external SD card, because I cannot root it.

I have purchased a 2nd hand Samsung galaxy s5 online. it wont et me access the phone as it is locked due to an abnormal factory reset and is requesting a Samsung account id and log in - clearly I don't have one and it appears it needs to be the previous owners. Is there a way around this in order to access the phone?

When my phone is locked I find on the bottom of the lock screen the emergency call symbol which, if tapped, brings up the option to then dial 999. Problem is with my fat fingers is that I keep knocking this and so bringing up the option to deal. Luckily I've always noticed and then cancelled so no mishaps yet.

I recently bought a used Samsung Flight online and it appears to be locked. The pictures in the posting all showed it unlocked, connected to Rogers etc and the phone is exactly as shown in the posting based on the nicks/marks on it. However, when I boot it up I am faced with a passcode. I've tried the standard 0000, 1234, 12345, 00000 etc but no luck. I've also messaged the seller but have not received a reply as yet.

I think I am having GPS problems with the latest BOGG baseband, I intend to try to downgrade to 5.0.2 baseband, I am not sure if this is possible or not. I know that you cannot downgrade from 5.1.1 ROM to 5.0.2 ROM, but not sure about baseband.

I am attempting to help a friend and also satisfy my curiosity. She has a Samsung "Rant" through carrier Sprint. She said that after her phone was turned off for non-payment, she can no longer use the phone. She claims she has been remotely locked out, as if you set a security lock code and forgot it, that kind of locked out. She swears the company locked her out to keep her from getting at her contacts. Is this even possible? I googled and the only thing I can find is blacklisting lock outs using the ESN, which I already realize. But to actually lock the hardware remotely, is another thing. I know they can remotely unlock. What is her best option to recover those important numbers, and do all carriers actively do this sort of thing (if it's even true?)

Just updated via Samsung Apps the camera firmware to a CDE11 or something version. Took 4 minutes to update and flash this firmware. I wonder what exactly it changed in the camera firmware? Hopefully improved things or bug fixes.I will test a few videos and see if the bitrate has changed or not.

I need to disable the "Reactivation Lock" to flash TWRP recovery from Odin (failing because of R/L) but everytime I try to turn it off and enter my samsung password it will turn back on. I tried removing samsung account or deleting it altogether but no luck.now I can't receive OTA because of Ping pong root and I can't flash because of R/L. the ONLY way to fix this is to flash the exact same firmware (and CSC) as the current firmware via Odin. I'll never use R/L ever!
