Warning: Leaked Galaxy Tab Firmware comes with Protected Bootloader

A note to those that are owners of Samsung Tab devices. The latest leaked firmwares come with a protected boot loader that disables custom ROM flashing abilities. From XDA Moderator Chainfire’s Post:

Some of these ROMs include new bootloaders. These bootloaders check checksums/signatures in various parts of the firmwares. The “normal” Samsung ROMs, nor custom ROMs and kernels, have these checksums.

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.

There is no known fix. I know, I’ve tried all of them some people suggested in other threads. None of them really works. Sure, with some effort, you can get a different firmware to somewhat run, but you’ll still be using the “checksum” bootloaders and the kernel will not be modified. You will still be running the kernel from the “checksum” firmware you loaded earlier. You will not be able to do full flashes, nor will KIES updates work.

Thanks Chainfire for the heads up, and for those of you with Tab devices be careful while flashing! To read the full warning, click here.

HTC’s New Ad Campaign And What It Really Means

HTC has just released three new blind test adverts comparing app loading speed, audio and selfies. Whilst you are surely astounded that HTC won every time, the tests were incredibly biased and their release shows something concerning about the company and how they are performing in the current market.     One of the many reasons companies tend to utilize blind trials is when they feel that their product is comparable or better than its competitors. This leads to the assumption...
