I use Weilei VP-280 with SOP44 adapter for 29F400, works correct.

I use BeeProg and PSOP adapter from obdfactory $900 (original, update from internet), never had a problem. I also have GQ-X4, it was crashing on me at times.

[mislav88]

check A19, probably you missed it

[k1champion]

thanks i check the box now i try and report this week

[electrix]

check A19, probably you missed it

For 29F400 flashes A19 must be disconnected.

I also use Willem PCB3 for years and I never had any problems.
Check by multimeter all signals on ZIF socket with HW Test in software. If there's all OK maybe adapter has some mistake.
Upload some photos of Your PSOP44 adapter and jumper settings - maybe I could help You.
