The Dat0 line of A04s is below the cpu. Is the cpu scratched or not yet ?

if the phone is in the state of EUB mode....
chimera can fix it via repair boot/unbrick method..
it will flash the BL, then you can flash with full FW

I couldn't scratch so I had to remove emmc form board and connect on BGA adapter interface so I could read emmc and I discovered that the boot configuration was 0x0 which seemed abnormal and and android software information wasn't coming up but the user patition was intact now I couldn't flash bootloader with Ufi since I wasn't seen the bit type of the phone I only changed boot configuration to 0x57 the regular mtk type which other exynox devices use and when I replaced chip to board device was still in exynox mode I'll have to chimera as adviced thanks a lot I'll keep updating

Hi Gujjarmobile789
Brother, on Samsung A04s ISP the DAT0 pin is only accessible after drilling the CPU, that’s why it connects properly only in that way. If the phone is dead after ISP, then please share which ISP method you used and also attach a clear photo of your ISP connection.
Also confirm:
After ISP, is the phone creating auto port in device manager or not?
Is it showing any kind of response (charging, detection) or is it completely dead?
Did the phone die immediately after ISP wiring, or after FRP reset?
Only after checking these details we can suggest the right solution.

First, the ISP connection used is not correct.
2nd, you should check each line one by one with a multimeter in GR mode, especially on the lines where you applied jumpers, to make sure there is no short.
3rd, if all the lines are ok, remove the CLK resistor and put a jumper on that point, then check again.
4th, if everything still looks fine, the next step is to remove the flash chip and test it directly on the box to confirm whether the chip itself is good or faulty.
If you want, I can provide you with the correct ISP pinout for this model which works 100%.
