Samsung Note 8, S8, S8+ new bootloader prevents flashing unsigned firmware

31 January 2018 1

Samsung is quick with updates and updates are always intended for the best interests of consumers or so you think. Well, sometimes updates may bring bugs, other times they may impose restrictions. However, this time it could mean locking your device forever. A new update has been rolled out for the Samsung Galaxy Note 8 and unfortunately, it comes with a new bootloader. So, why would a new bootloader be so bad? After installing the update, you will never be able to downgrade your device or flash the firmware of another region on your device.


This is because the new bootloader isn’t supported by the tool used to flash the firmware to the smartphone. A tweaked version of Samsung’s Odin utility called Prince Comsy’s modded Odin, which was used to bypass flashing the firmware of one region on to a phone with the same SoC from a different region even though the model numbers didn’t match. However, that isn’t possible anymore, all thanks to the new bootloader!

Prince Comsy’s modded version of Odin no longer works with this new bootloader so if you goof up while flashing, you could very well end up with a smartphone which is hard locked. You will only be able to flash builds which have been officially signed by Samsung. In laymen terms, if you have a U.S based phone and want to flash it to the Canadian firmware, you cannot do so anymore. The Samsung Galaxy S8 and S8+ haven’t received the update as yet. However, once the ROMs get the BLv3 revision, you will not be able to downgrade on these three devices. This is a huge way limits a lot of developers and users when it comes to custom ROMs.
