hello strix666 unfortunately your problem may not be fixed for some causes :
1. your phone is a low quality phone (sorry for saying that)
2.before huawei created the phone some documents leaked and many companies created clones with much lower quality
3. this is a common problem with this model of huawei phone so don't be surprised if it has gone BRICKED without anything
and i wanted to know what were you doing with the phone (with details) before that happens and did you try to had reset it?

dear strix666
i'm very sorry but the (recovery_TWRP_2.6.3.0) is a recovery used for lenovo phones specially lenovo p780 and as the most common results there are 3 things that happen :-
1. the phone gets bricked possibility : %70 (your current phone situation)
2. the phone gets stuck in a boot loop possibility : %22 ( thats what happened to your phone at the first flash )
3. the phone stays safe and nothing happens possibility : %8 ( impossible )
and so after you tried to fix it by flashing it 2 times again it is commonly bricked which can't be fixed easily and the only way to fix it is by using apps similar to odin.
but before that i need to need know some other details :-
1. does it charge or show the charging icon?
2. try to hold the volume down and power key for about 15 seconds anything happened?
3. connect it to your pc and go to | start menu > devices and printer > right click your device > troubleshoot
and if it doesn't appear please tell me.
by the way my name is paywand and sulaimaniyah is my city

Since you can reach recovery mode,
Try flashing the rom I released few days ago in the development section.
Press thanks if I helped you

First of all to say thanks,you can press the thanks button on his/her post,it helps keeping xda clean and on track.
Now as for your problem what I think is that your system partition memory has corrupted,
Recovery is stored on separate partition so you are still able to access it.
Elsewhere your motherboard and all is intact cause you can run the rom installer and execute commands to.
I strongly recommend getting your phone to a service centre for help,
Noone here(I guess) can help you deal with hardware issues.
One more thing, have you tried restoring your system via wmshua flash tool,
You can find its tutorial easily in the forum. Try it before spending money
Press the thanks button if I helped you.

I can't change my rom, wipe / format doesn't work. Nothing changed after flashing with Odin.
16 GB Tab 2 have a known faulty EMMC (MAG2GA). It can happen, that your EMMC get "read only", so you can't perform any write actions (also you can't format) anymore.
From the EMMC data sheet:
5.1.7 End of Life Management:
The end of device life time is defined when there is no more available reserved block for bad block management in the device. When the device reaches to end of its life time, device shall change its state to permanent write protection state. In this case, write operation is not allowed any more but read operation are still allowed.
But, reliability of the operation can not be guaranteed after end of life.
On a faulty EMMC firmware it happens a lot faster.
What are the symptoms?
Uninstalled apps and deleted files are back after a reboot
Formating the storage doesn't work (after reboot the old rom and apps are back)
You can flash whatever you like via Odin - it showes "passed" but after reboot nothing changed (e.g. still no StockRom or still the old Recovery you had previously installed)
... there might be some more, but only to mention some ...
In most cases, the issue can be fixed by a EMMC firmware update, but you need someone who's able to do it (possible via ISP, nothing you can do esylie at home yourself). In some bad cases you need to find someone who can replace your EMMC.

Need Help with Huawei Phone Major Problem. Experts Needed >

Okay i have a really big problem with my phone ( Huawei y7 prime 2017 TRT-L21a )
How the Problem Started :
the phone was working very fine while rooted and unlocked , didnt face any problem at all and once it happened that i decided to install Xposed framework and modules , i did install the latest and the most suitable for phone version yet no modules appeared so i had to go into twrp to install modules and stuff , i noticed that the phone couldnt boot and went into bootloop problem , had to format factory but ACCIDENTLY erased ALL data including SYSTEM , P.s im not a noob with root stuff , The Major problem showed up i Couldnt even get Past The sign of * ur phone is unlocked , OS is booting * , so i went on surfing the internet for answer and solutions but it was all invain for complete 30 hours without sleeping and having a heart attack !.... every time i proceed i find problems Like FRP LOCKED and USB DEBUGGING LOCKED and ADB DEVICE NOT SHOWN . UNABLE TO ENTER RECOVERY MOD , etc......
i ve Tried every thing and followed every video instructions , also xda developers instructions , And many websites .
i downloaded all compatible dload (update.app) zips and everything but i couldnt install them as they reach 5% and get stuck and the phone then reboots in loops
So now , 1) i dont have OS
2) no USB DEBUG
3) no FRP unlocked
4) no TWRP or Recovery ( the erecovery stucks at 61% and then reboot loops )
5) i have only got fastboot state and written on it phone unlocked.
So The Fix i need and i really have a big hope that it will fix it which is :
1) a way to unlock USB DEBUGGING for my bricked phone using Pc which i didnt find all over the internet
2) a way to install TWRP recovery using Pc (but not the ordinary method ) i need it to be installed through dload
3) ALL MY OS FILES STOCK ( RECOVERY - BOOT - SYSTEM and others )
Whoever find me a solution , i will be in his debt for a life time as im really Got nothing to do for it , im literally useless rn
MANY THANKS IN ADVANCE.
