Dare I ask what you flashed? Also, did the process complete successfully, or else what error messages did you get? When trying to diagnose problems over the internet, as much information as possible is helpful, and we only know what you tell us.

"Flashing" incidentally is just a term for directly writing software to the phone's storage, so could cover quite a range of operations. If you flash the wrong software for your device it will make the device unusable, and in the worst cases (e.g. if you damage the bootloader) there may be no way of fixing it - so let's just hope that isn't what you have here!

Can you also tell us exactly what device this is? My guess is that you'll need to reflash a set of stock software (if you can get it into the mode where you can do that), but it has to be the software for that device - not just another one with the same processor or by the same manufacturer.
 
i flashed kasty-onda_v972_v2-442-v44-rooted and i don't know whether the process is done or not because nothing is loading on the screen after i flashed that rom and i don't know what device is it because there's nothing on the board and on the back of it and the software i got when i received the tablet was not stock rom

If you don't know what your device is or have a backup you have probably killed it.
 
i didn't get the box as i was gifted with that tablet and i even opened it seen the board there's nothing on it though if u want a want to see it i can send u a picture of it and i most probably think it is a study tablet but was installed a custom rom on it and was given to me so there must be a way to get to hard reset it
 
Trouble is that hard reset doesn't do anything to system software - it just wipes stuff you've installed. These devices don't waste a couple of GB of storage keeping a spare copy of the system software in case you make some unauthorised changes, so a hard reset won't fix corrupted system software. That's why when playing this game (which, incidentally, I do with all of my devices) it's important to only use the right software and to back up everything you can anyway.

If you could get it into the mode in which you did the flashing and we could find th right software it could be recovered. Otherwise someone who really knows that model and has access to a piece of kit called a jtag rig could probably find a way of recovering it. But if you don't even know what model it is this will be very hard. I don't suppose th person who gave it to you (and presumably rooted it) could tell you?
 
well i flashed the rom using my pc the software i used is phoenixsuit i even flashed twrp but i was not being able to use it cause it was not responding and was bigger than the screen size of my tablet so i could not make a backup of my my rom i had previously do u think if i give it for repair they can do it
and even the screen is showing white screen on my device now it is turning on but white screen is coming on the screen
 
That third shot suggests that this is a tablet that was supplied by this programme. That may help someone track it down, though I've not yet found any details of what model (or models) they supply. Did you have a reason to believe it is an Onda V972 tablet (which is what that ROM was designed for)?

The fact that the TWRP you flashed was written for a different screen resolution was actually a huge clue that you'd flashed the wrong version for your device. If it had worked it could well have caused a lot of damage.

The worrying thing is that you can't get it into the mode you used for flashing (most likely fastboot mode). If you can't do that there's nothing else we can do here.

As for repair, someone with the right knowledge and equipment could probably do it - it's a matter of whether they can recognise the device and find what's needed.

well at first i wasn't sure what i was doing but i've seen the custom rom in this website at first and flashed the twrp for vOnda 973 using update app in my tablet but it was struck in the twrp screen for one day and i was not able to get out of it but any how i bypassed that and i again downloaded vOnda 972 twrp and flashed it but it was still the same resolution as before it was bigger than the tablet screen was and not responsive i've downloaded the twrp from here

and seen many other roms and downloaded vOnda 972 the rom from above link
and used phoenixsuit software for flashing the rom and after flashing the rom there was only white screen with light but nothing loading on the screen tried every combination to go into some menu or hard reset and to even get something load up on the screen and as i told because i could not flash the twrp correctly i was unable to make the backup
 
is there anyway if i can boot up my tablet using the micro sd card by installing the android os in it or anything if it is possible anyway
 
No, you won't be able to boot it from SD (which is only loaded towards the end of the android boot sequence) unless that ability was written into the bootloader. I can't offhand think of a device which includes this.

I've gathered that you'd tried loading software for the vOnda 972 and 973 tablets, but my question was whether you had any reason to believe that your tablet was one of those models? Because I've not so far found any mention of what model of tablet that educational company distribute, so wondered whether you did have some information, or whether you'd picked those because they had the same SoC?

The tablet not booting is one thing, and as you say you don't have a working recovery. But the real test is whether you can get it into the bootloader? This generally involves shutting it down then booting while pressing some button or combination of buttons, which will vary between manufacturers (but volume buttons are a good place to start). Some of what you posted before has given me the impression that such things are also not working for you, but I want to be sure. Note that shutting down first (e.g. by pressing and holding the power button) is important. If you can get it into the bootloader there is still hope - if you've corrupted that then you'll need a repair shop with specialised hardware to have any chance of recovering it.
 
if none of them are working then there must a reset button on my tablet or a special combo of buttons which i think not able to find out there are only three buttons on my tablet 2 volume buttons and one power button
 
The only reference I could find to that motherboard is this Russian forum post. The device they refer to there seems to be for the Russian market (all references I could find were in Russian), so probably not the same tablet. I would imagine that budget tablet makers will use off-the-shelf components, so wouldn't think that the motherboard itself would suffice to definitively identify it. The poster in that forum was incidentally having problems finding firmware for his/her tablet that would work, and the person who replied to them just suggested using adb to backup (not your problem, and won't work in your current state), so I doubt there's any help there.

You never answered the question of whether the person who gave it to you knows what device this is.

As for getting into the bootloader, yes, booting while pressing one or other volume button, or both, or in combination with power, is the sort of thing I'd expect. If no combination works that's a bad sign. As we've said, a reset button wouldn't help you anyway: you've corrupted the tablet's firmware, and a reset (erasing the /data partition, i.e. user installed apps and app data) won't change that at all.

I'm sorry, but I am out of ideas here. It's actually quite hard to really kill an android device, but if you can't get it into fastboot or download mode then I think your only hope is to go to a repair shop and tell them the situation (that you don't know what tablet model it is but tried flashing the software anyway and bricked it) and ask whether they think they'll be able to do anything.
 
i can't contact the person who gave me the tablet now cause he's outta town and he left the tablet's box at his home and brought only the tablet and charger which he bought for me recently i will ask the person soon about the tablet but it might take a couple of days to find out i guess he don't have an answer cause i already mentioned that he bought that recently and might not be familiar with the tablet
