PLEASE HELP Moto G4 fastboot broken

I wanted to fresh wipe my phone with a stock ROM, and well I really messed up. My bootloader was unlocked, and like the stupid me I am, I believe I accidentally locked it again. Now, when trying to re-unlock it using fastboot oem unlock UNIQUE_KEY I get the error: (bootloader) invalid boot state That would be fine, if I could boot up; when I boot up, I get a "start up failed" on my device. The absolute worst part is that I cannot flash anything, not even the stock ".img". When trying to flash anything, I get the error target reported max download size of 536870912 bytes sending 'recovery' (13798 KB)... OKAY [ 0.468s] writing 'recovery'... (bootloader) Image recovery failed validation (bootloader) Preflash validation failed FAILED (remote failure) finished. total time: 0.530s Any help would be greatly appreciated! I hope I can get my phone back and running again soon, thanks! ---------- P.S. my fastboot getvar all returns : (bootloader) version: 0.5 (bootloader) version-bootloader: moto-msm8952-B1.05 (bootloader) product: athene_13mp (bootloader) board: athene_13mp (bootloader) secure: yes (bootloader) hwrev: P2A (bootloader) radio: 1 (bootloader) storage-type: emmc (bootloader) emmc: 16GB SKHYNIX HAG4a2 RV=08 PV=E4 FV=00000000000000E4 (bootloader) ram: 2GB SKHYNIX LP3 DIE=8Gb M5=06 M6=03 M7=00 M8=1F (bootloader) cpu: MSM8952 (bootloader) serialno: ----- (bootloader) cid: 0x0032 (bootloader) channelid: 0x8d (bootloader) uid: BC936D0100000000000000000000 (bootloader) securestate: flashing_unlocked (bootloader) iswarrantyvoid: yes (bootloader) max-download-size: 536870912 (bootloader) reason: Volume down key pressed (bootloader) imei: ----- (bootloader) meid: (bootloader) date: 10-30-2016 (bootloader) sku: XT1625 (bootloader) battid: SNN5970A (bootloader) iccid: (bootloader) cust_md5: (bootloader) max-sparse-size: 268435456 (bootloader) current-time: "Mon May 23 20: 8:35 UTC 2016" (bootloader) ro.build.fingerprint: motorola/athene/athene:7.0/NPJS25.
