Samsung Epic 4G owners who have converted their phones to MTD partition layout can "flash" this in MTD recovery. It temporarily boots CWM5 BML, allowing you to flash modem upgrades without wiping your phones back to BML layout. You may safely ignore the error messages when this CWM starts. This CWM is not written to your phone, so the next time you run recovery it will be MTD CWM.

Requirement: Your CWM recovery kernel must support kexec. CM7 kernels nightly 12+ support kexec.

Worked like a champ, updated to EL30 modem, running MTD with CM7. This is a GREAT idea. Nice work

OK, so this boots a BML CWM recovery for just that flash and does not touch the MTD CWM5 on the phone? That is some fine work my friend!!!!

What do you flash to get back your original recovery?

It is temp booting into this recovery with kexec. IIRC there is also a way to kexec from a PC over USB if you mess up your kernel/cwm.

Could we have a detailed instruction for idiots please or perhaps QBKing could make a video. This is a significant and important piece of development work. Congratulations!
