Repeated attempts to upload to Pro Mini via FTDI ("Basic") fail

Connections:
Have you successfully used the FTDI before ?
Connect RX to TX on the FTDI and open the serial monitor.
Send text out on the monitor, does is the text get received back.
Iused the FTDI before but that was several months ago. In my current case I did connect RX on MiniPro to TX on FTDI (and, yes, TX on Minio Pro to RX on FTDI. I was not able to use the
Serial Monitor because the connection was not made (failure to upload). I will try communication to Serial Monitor anyway. Thank you for your help.
Yes; the text was echoed back. ????? HOwever, the upload fai
led, anyway.
Try a different Pro Mini.
Assume you have the IDE set to Pro Mini ?
You may need to re-burn the bootloader.
I will RE-try using other Mini's I tried two or three. I will, again. By the way, I am using the "BASIC" 5v FTD1 but I did try the FTD232 with no success. I even tried using a plan to Upload through a "UNO" ("instructables". The IDE is set to pro-mini.
I think I am ready to take my current setup apart and re-wire everything. Thanks, again. I should put the thing away for a week and then try a new beginning,
By the way, the LEDs (TX) on the FTD1 occasionally flashes, but the RX LED does not. Usually two errors (programmer not found and Sync) are reported. On some occasions only the SYNC error is reported.
Hi,
Are you ProMinis, 3V3 or 5V models?
Google;
difference between 3V3 and 5V arduino promini
Thanks.. Tom.. 
5volts
You may need to re-burn the bootloader.
Error message: "Missing programmer"
Added info. On the mini the green LED is flickering while the red one is steady on.
Read thru this discussion, you can adapt things for your Pro Mini.
Added info. On the mini the red LED is steady on while the green LED is flickering.
when you selected Tools>board "Arduino Pro or Pro Mini" did you select the specific processor?
e.g. I am using a 3.3V 8MHz Pro Mini
if I select the wrong COM port or wrong processor, e.g.ATmega 168 I get
Using Port : COM12
Using Programmer : arduino
Overriding Baud Rate : 19200

I selected ATmega328P (5v, 16MHz),; that is the correct coice, in my case. I can TRY 3.3v, 8mhz
This is quite the task, eh?
Changing the processor choice did not change the result.
Not really.
You do need a programmer board, the basic UNO will suffice.
@tmkane
Exactly how are you making the FTDI to ProMini connection/s?
I will read through the gammon docs, Do I need and ICSP (?) cable to connect the uno to mini?
