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.

Glimpse Notifications: Easier Lockscreen Notifications

Lollipop brought a revamp to the lockscreen, taking away custom widgets but showing your notifications instead. If you're a fan of that, you might want an easier way to check your notifications as they come in, without losing your current lockscreen. Glimpse Notifications by XDA Senior Member xrad offers just that. You'd normally have to turn your screen on manually to see your notifications. Instead, Glimpse Notifications will do it for you when a notification comes in. That doesn't mean...
