How do I reflash Alcatel 5054N Android ROM without PC...

[rob_borg]

I recently purchased Alcatel 5054N smartphone on ebay...and all was running well until i installed an app named TWRP;it seems that this app had erased/wiped my system partition after a recent reboot,and is basically taken over for Android Lollipop!!?!!

What i need to know is where may i find a stock ROM for the make,model of smartphone phablet mentioned,and how to reflash the phablet/smartphone back to OEM stock condition???

Thanks in advance for any and all replies!!
