i rooted it, so i used an app to boot to recovery mode then i tried going back , i found out i was in a bootloop. so i went back to recovery mode and  restored the backup i made, after restoring and rebooting recovery mode also went into a bootloop, so i had only access to download mode, then i tried to flash it with a firmware i got from tsar3000.com for my device model but a different region, then i flashed it with odin and i got the result as fail on odin. i tried switching the tab on but to no avail, it wont come on or show sign that its charging. it only shows as device error when connected to pc. please what do i do now?? i need your help

unfortunately, we dont provide offline services ATM.
the phone might've gone dead due to an incompatible ROM flashing attempt or an Odin interruption. 
1. what error do you get when connected to PC via US cord?
2. when you connect the phone to PC, what does it get detected as under device manager?
3. have you downloaded the drivers for your phone model?

My pc makes a sound when its connected, and under device manager it shows as EMEI with an error icon, and yes I have the drivers for my device model... What do you think I can do now to fix the tablet, I went to an individual technician in ikeja and he says, he can fix it but for 8000naira, I assume that's just too much

since the battery is inbuilt, you'll need to pry it open. do you have the tools?

if this doesnt work then you'll need to JTAG
take off the back cover and disconnect the battery. connect the phone to the PC without battery and let me know if it makes any sound
