Low Voltage Error- Tried everything

I have been getting the:
Voltage is 4.23
voltage is too low
error when flashing with ecuflash.
ive tried jumping the flashblock (tapping into the wire that loops) to the battery.
ive tried tapping into the OBDII 16 pin (12 supply) to the battery, which i think has messed up my OBDII cause now i get a get kernel error.
ive tried tappin in the OBDII 4 pin (ground) and grounding it out.

all this with a battery charger connected.

I have a 02 usdm wrx and ive heard they have a problem with this. I have however tried everything that has worked for others and came up with nothing.

if you know if tapping into the 4 and 16 pin could have messed something up that would be helpful too cause now im worried. thank you in advanced.

The low voltage error usually comes up if you forget to jump the flashing connector-so i presume that when you tried to flash that you joined the 2 green connectors and you had a bad connection bridging the other single connector.

i had the green test connectors connected and have a brand new setup. they were suppose to fix the problem with the flash block where they had a loose connection issue. how would i determine if i have a bad connection at the flash block? also, would spicing into the obdII at pin 16 and 4 cause a problem?

Best way to know if the flash block connection is ok is to test for no resistance over your block connector (the one you plug into the flash block)
Cant help you with splicing into the OBD wires-you shouldnt have any need to do this-why have you?

Just an idea-
Check behind the passenger footwell plastic side pannel-on mine there was another set of green connectors(the same as under the dash)-these should be permanently connected(theyre linked with the dash ones)-
I had an issue where i couldnt read/flash and got the "kernel get version"
error come up, i eventually found these plugs disconnected by pure chance!! Once connected,everything worked fine.

popped the door panel off of the passenger side and found the green test connectors. they were already securely coneected, so that was no good. thanks for the suggestion though. back to square one :(

Well-i dont know then.
Have you managed to read the ROM yet?
If not then you may have a problem with COM port settings-i also got the kernel error when i had a modem using the COM3 also which caused a conflict between the modem and the tactrix cable-i just changed the modem to another COM number in system devices on the PC.

before i cut the OBDII wires i could read the rom, but it wouldnt enter test mode (fans cycle, etc.). after i cut them and connected them back, i get the get kernel error, but it now enters into test mode. ive tried two different laptops lately and get the same thing.
