Updated r39222 to r40004 (md5 is ok) at a wr1043nd v1 (flash via Webgui + keep settings - near to stock) lead to a hard brick of the device (flash looks ok, rebooted and never come up).
Serial cable is ordered and maybe i can recover it.
All other recover/reset/... methods won´t work. It seems it didn´t even pass the boot manager (guessing from the led activity).
The firmware files at r40004 are 500kb smaller as the r39222 don´t know if this is ok (dropped some packages ... ).
