HTC DUMLOCK - Flash boot from recovery without fastboot! (Updated 2012-02-28 v2)

Dees_Troy · Feb 22, 2012

HTC Dumlock

HTC Dumlock is a workaround for devices with HTC's unlock that cannot flash boot from recovery. Put simply, we make backups of recovery and boot, then we flash the backup of recovery to boot. When you reboot normally, you'll be in your recovery, but since your recovery is flashed to boot, you can make changes to boot. Head on over to our website for download links and instructions.

NOTE: The Rezound does not have TWRP, so you will be using the universal version!

New v2 version scans / compares the backups of boot and recovery to help ensure that you don't run it twice and wipe out your backup of boot.

I believe I can unify all of the zips into a single one that is touchscreen based

It would make it extremely easy and useful.

Con,
I hope your professor's appreciate you !

I was hoping you would simplify it.

Quick question, so reading through the website a few times. It is my understanding once this is properly set up when we make backups it will be backing up the kernel and when we restore backups we wouldn't have to reflash kernel or am I taking it to far ?

Also would our backups from Amon Ra still work or better to just delete them and just make fresh backups of current rom with TWRP recovery.

There's 2 versions, one is the universal version that works with any recovery. The other, the TWRP version, is only available for a handful of devices and that doesn't include the Rezound. I don't have a Rezound, so I can't speak for it myself, but I would imagine that your existing backups would be fine (you could read boot, just not write to it) unless you chose not to back up boot.

I believe once I rebuild it specifically for the Rezound it will clear the confusion surrounding the purpose and use of the tool.

I look forward to seeing where this goes...

This may be huge. Invaluable tool if used properly.

I wonder if this same technique would work using "fastboot boot recovery.img" instead of actually having to save / flash / restore the boot.img?

I've been asking the same question

Yes, but the point is to avoid fastboot.

True. But I would think there would be a way to duplicate the fastboot behavior and boot from an alternate image file without requiring the use of a PC.

Dees_Troy · Feb 22, 2012

You can only issue fastboot commands from an external device via USB while your Rezound is in fastboot mode in the bootloader.

Not quite. I don't believe the fastboot method actually flashes anything to the boot image, so this method leaves more room for error due to the process of saving / flashing / restoring the boot image.

Totally awesome gentlemen. I cannot wait to install this on my phone.

That is the only way to do it without fastboot.

I am building a GUI for this so it will be pretty sick. Should be out tomorrow night.

Sure, but this method doesn't require a computer (or other external device) for those times when you are away from a computer. You can't do the fastboot method without a second device.

The 3D had a program called Flash Image GUI. It did what we're trying to accomplish here. Interestingly enough the program "worked" but it wasn't nearly as reliable as the fastboot method

And please don't take any of what I say a hating. I am merely discussing and spitballing. Lord knows that with the drama over at the 3D forums and Chad kernels I am not trying to bring that hate here. Not in the slightest.

I will post this in the other thread too. Thanks for all your hard work sir!
