At the time, I did not have a BMP or any STM32 capable of being flashed as a programmer.
I figured the jlink clone might be useful in the future, but I definitely think the BMP / diy programmer is the way I would have gone if I had one sitting around.
@sancho119 No matter what I tried, I could not unlock the E73 with the STLink.
I had to buy a jlink clone, download a bunch of segger debugging tools, use the segger tools to override the lock flag. After that I could flash the bootloader.

#To share my experience with the nRF52832.
#I was unable to disable the read protection / flash lock with a BMP or ST-Link V2, but i was successful with a J-Link.
#When nRF52832 chip is read protected / locked, the first step is to try:
nrfjprog –recover -f nrf52
#This performs the same task as:
Jlink -if swd -device nrf52
J-Link>SWDSelect
J-Link>SWDWriteDP 1, 0x50000000
J-Link>SWDWriteDP 2, 0x01000000
J-Link>SWDWriteAP 1, 0x00000001
#Wait until AP 2 is 0, and the operation is complete
J-Link>SWDReadAP 2
#If two successive reads from AP 3 produce 0, then 1 then protection is disabled
J-Link>SWDReadAP 3
J-Link>SWDReadAP 3
#Tested with JLink v6.20b

I've tried the E73 Ebyte NRF52832 modules, various NRF51822, and "diymroe" STM32F407, all with the same result...not seeing anything and nothing to serial out.
Somebody with more experience with hardware debugging could probably dive deeper using STLINK / JLINK tools.
I know there are a few issues related to their use on github:
https://github.com/mysensors/NodeManager/issues/463
https://github.com/mysensors/NodeManager/pull/438
I also remember the project owner, @user2684, mentioned he doesn't get notifications from the MySensors forum, best to open an issue via github.
Interesting. I might be using a different library. I would stick with the LowPowerLab version, looks like sleep is equivalent to power down.
#define SPIFLASH_SLEEP 0xB9 // deep power down
https://github.com/LowPowerLab/SPIFlash/blob/master/SPIFlash.h line 82
I guess I'm using this library, https://github.com/Marzogh/SPIMemory. It was renamed to SPIMemory.
@xreichardx I have not tried the myscontroller bootloader, sorry.
I had similar high power consumption issues with this NRFduino from electrodragon. It turns out it was the attached flash module that was consuming a lot of power.
I was able to reduce the sleep current by immediately powering down the flash module.
