Cannot install sketches or bootloader to DFRobot pro mini

I am unable to upload sketches into SFRobot Arduino Pro-Mini. I have three of them, all exhibiting the same problem.
I don't get the traditional blink indicating the boot loader is installed.
I have tried to install a new bootloader using the "Arduino as ISP" with a known working Pro-mini, but with no luck.
What is wrong with these boards ????

2016-06-22 19:29:14 Thank you for all this work, Leff, but I fear you have missed the point.
NONE of the Pro Micro boards will accept a program using either of my two FTDI USB to Serial adapters.
NONE of the boards will accept reprogramming of a boot loader either.
All 3 are brand new boards from DFRobot, yet none of them accept code. They seem like they are trying (flashing lights), but programming fails.
I have two Pro Minis from other manufacturers, that DO accept programs, also a Due and a Mega 2560 from other manufacturers. All of them accept programs.
The three Pro Micros from DFRobot will not accept programs or a new bootloader.
So again, what do I do with these DFRobot boards? Is there something special I need to do to program them with a bootloader? Your instructions above are for loading sketches, not bootloaders.
Thanks!

2016-06-21 20:23:43 Hi j.opificius,
Take an Arduino controller as an ISP programmer could do the job to flash the bootloader, it often used to save a defective arduino board lost bootloader. But to program a sketch, it is very complex that I haven't tried yet, but it can as I know. For more info, here I wrote a post which could be found in Good to know, Arduino common problem (updating).
And as long as you have that programmer, you can do it easily then. Plz contact the seller or find how to online for yours. Also you could take ours as a reference. They should be very similar.
Plz see my next post about how to use the USB adapter.

2016-06-21 19:36:44 Leff,
I've tried reprogramming using both another known working Arduino Pro Mini ("Arduino as ISP") and a known working classic Arduino ("Arduino as ISP"), using instructions on the Arduino website.
I do have an Inland FTDI USB to serial adaptor which has the 6-pin header, and which I understand should also be able to do the job, but I don't have definitive instructions on how to use that.

2016-06-21 02:57:15 Hi Sorry for late update,
May I confirm what programmer you used?
I will have one tested tomorrow.

2016-06-17 06:19:55 Thanks for the reply; it's the 16MHz 5v one, DFR0159.
I've seen a lot of chatter on the Internet with regard to problems these third party xxxRobot board. These DFRobot devices were purchased for a professional application. The Inland devices I bought for personal use were half the price and have worked perfectly.

2016-06-17 01:24:54 not sure, I have not used this board, may I confirm which one you mean, I found two similar...?
