General Be Careful Resetting Samsung A22 - IMEI become Unknown!

[demoimoet]

This actually happened on Samsung Service Center (SSC), yesterday they try to reset Samsung A22 and IMEI unknown. Modem part become corrupted. Updating device to new version will not solve the problem.

So, i actually still confuse why this happen? Mediatek Helio G80 is unstable?

Don't know how to resolve this issue, because it's MTK maybe there are no ISP pinout to direct programming. Unlike Qualcomm or Exynos, which always exist for ISP pinout.

Maybe secure modem file will solve it but i don't see MTK bypass for this chipset.

Any of you maybe have the same problem with new security on Mediatek chipset?
