On my HTC one hboot 1.44.000, I can run i ADB
fastboot boot boot boot.img
To boot on a custom recovery image without actually flashing the image.
On newer HTC one hboot 1.55.000 this has been disabled.
Does anyone know of any workaround to this problem?
Its a bit of a pain to do the initial backup of the stock recovery, rom and boot when you have to overwrite the stock recovery to do so.
Can the stock recovery be backed up to an img file from the ADB prompt, with stock recovery still loaded somehow?
In fact its a classic CATCH 22
I know you can extract the stock recovery later on from a the latest OAT update, but it would just be a lot more simple, if all you what is root, to boot on the image without flashing, install the super user app, then restore all the needed HTC specific apps you lose when unlocking and then you are back to stock with root.
Does anyone know the exact location of the OAT from where you can extract the stock boot and recovery from firmware.zip, and is this OAT deleted after it has been run, or if its still available to grab later one?
Since the device is not rooted yet, its not possible to check the \cashe folder for the OAT file before you rooted it.
What if its not there? How will you find the original stock recovery that fits your current system, any new OAT may have a different one, that mayl not work.
Again a CATCH 22
Why does HTC support unlocking the bootloader, and then limits it use, not allowing to boot on a recovery without flashing it ?
