Only bootloader accessible after MacGyver-style

[phaetjay]

Hi people,

I have a Motorola Defy plus (MB526) lying around. Because it is such a nice phone, I'd like to use it as second/backup/emergency device, but my last attempts to install a not-completely-outdated OS failed miserabely.
Now, the phone is in the following state:
- Power button does nothing, vol down + power also nothing.
- When plugged in, white LED is on, but battery apparently does not charge.
- Vol up + power gets me into a bootloader screen, but I have a "battery low" error message.
- By destroying a USB cable I was able to manually connect 5V to the battery when inside the phone, so I now get: Battery OK, OK to program, transfer mode USB.
Also, when now booting, the Motorola sign appears for a few seconds and the phone gets stuck in the boot animation of an old CM version that I previously tried to install.

Does somebody know how to proceed from here to flash any functioning ROM? Or to flash TWRP or CWM?
Can I somehow access the phone in this state using adb? Could fastboot flash recovery work (at the moment, I only get <waiting for device>) after getvar all?

I would appreciate any help. Thanks a lot,
Jay

Flash the correct SBF using RSD Lite or sbf_flash to your Defy+ MB526 which would be using CG version 5, 6 or 7. I recommend flashing a lower CG SBF such as DHT-22 SBF. Then wipe data/factory reset in Motorola Stock Recovery by pressing Vol Down and Power Button simultaneously. If you get a black screen then flash a higher CG SBF.
