Samsung Galaxy Tab Firmware Leaks Show Locked Bootloader

A newly leaked Samsung Galaxy Tab firmware show that the Galaxy Tab have been shown to contain protected bootloaders that 'disables custom ROM flashing abilities'. Flashing to the leak has resulted in various reported unrecoverable bricks if Odin is used improperly to attempt to revert to a previous unprotected bootloader. If you want to maintain custom firmware flashing functionality, do not the JM6/A/C/D ROMs!

The result is that once flashed, you cannot revert to older/official/custom Samsung ROMs, and you are pretty much stuck using one of these four ROMs, as they are the only ones containing the right checksums.

This may indicate that Samsung is leaning towards limit custom firmware development by locking down the device.

They have been working on a fix for the people that had installed the listed custom ROM's and I think Rotohammer has found a fix but I'd check on XDA to get the full scoop...

Honestly, I hate to say this, but this would not be a surprise long term. This is similar to the model Archos has always pursued and Apple has done with their builds. The ability to lock and control the ROMs is a major limitation for Androids to get products like NetFlix or buyin such as Military/Govt contracts.

The DRM issue of Netflix is a real pain, but it makes ROMS like Archos or potentially Samsung a reality. The flipside of the consumer is impacted in loss of control. But it makes it a "stronger" product for security controls and inability for modding and placing a spyware rootkit.
