BITMAIN ANTMINER E-3 CUSTOM FIRMWARE

I have Bitmain Antminer E3’s, originally they came with 4gb memory, I believe ddr4, which is not enough for mining Eth anymore. I have a new control board that replaced the 2-2gb memory with 2-4gb memory, however the firmware doesn’t automatically recognize the upgrade. I need someone to customize the firmware to recognize and adjust accordingly, to be able to use the miners again. Also I want the frequency and voltage of the ASIC chips to be adjustable in the configuration menu of the web menu. Not SSH. BEFORE YOU PLACE YOUR BID, keep in mind that someone on here has already bid 250$ to add the adjustments to frequency and voltage in a matter of 2 days. I expect you to bid more, but 750 is not really feasible considering the earlier bid. I need this done soon, can’t wait longer than 7 days. Please bid accordingly. Thank you
