Hi everyone! I tried to install linux on my MBP 2015 A1502 and broke something.
Now flashing question mark appeared when MBP starts. Disk utility can't find ssd (adata sx6000pnp) either.

I used Parted Magic USB, NVMe Secure Erased ssd and then used GParted to create GPT partition table. I also created HFS+ partition on it.

So now I can even write some files on ssd from Parted Magic USB but ssd is still invisible in MacOS Recovery mode.
What can I do with it? Thank you in advance for your suggestions. And sorry for my English, I'm not a native speaker.

Using GParted, etc., probably wiped out the recovery partition as well.
Booting to internet recovery on a 2015 MBPro will likely boot to either Yosemite (OS X 10.10), or El Capitan (OS X 10.11). Neither will see the NVME device. You will need to boot to a bootable installer on an external USB drive - minimum of High Sierra.

Time to:
a. boot to INTERNET recovery (Command-OPTION-R)
b. open disk utility
c. go to "view" menu and choose "show all devices"
d. select the internal physical drive (top item) and ERASE it to APFS, GUID partition format
e. re-install Mac OS.

Internet Recovery Disk Utility is unlikely to help at all. The OP says that the internal drive is an ADATA SX6000, which is an NMVE device. Internet Recovery on a 2015 MBP will be either 10.10, or 10.11, at the newest. Neither OS will see an NVME drive, not even as an "unknown" device.
OP will need to boot from an external, using at least 10.13 (or newer)

Reviewing the posts above. OP said he bought the MBPro, used, with that SSD already installed.
It will be using some kind of internal adapter.
An "Adata" brand would NOT be OEM (unless I have moved into an alternate reality, somehow)

OP needs to boot to a system version that has a hope of actually showing that NVME device.
Best chance is to locate/make a bootable macOS installer, minimum system would be macOS High Sierra.

Or, find an OEM storage drive, which may make this process simpler, without the struggle to boot to a system that actually supports that NVME drive -- Internet Recovery would actually find an OEM drive. It can't/won't see that Adata PCIe drive.

The default internet recovery version (Command-option-r) will be the newest that’s compatible with that computer. Command-option-SHIFT-r will attempt to install the original OS.

Wondering if the OP could:
1. boot to internet recovery
2. install the OS onto an EXTERNAL USB drive
3. would boot/install this way also upgrade firmware?
4. then, once the external drive has the OS installed, CLONE IT OVER to the internal drive...?

Firmware updates require an original Apple SSD inside the MacBook; however, if the MacBook is running the latest Mojave firmware, updates can be done with an internal NVMe drive.
