    Based on this post,
    https://jb8a8f8.com/support/index.php?threads/search-new-image-for-x-solo-mini-2-clone-evoe3hd.387/
    Then it must be a toshiba nand flash chip, I think the TC58NVG3SOFTA00

    The bbs xml file data should then be this,
    Code:
    <?xml version="1.0" encoding="utf-8"?>
    <Flash maker="Toshiba" name="Toshiba TC58DVG3S0ETA00" type="NAND" technology="SLC">
      <Command type="Nand" programmode="Block" maxbyte="4096"/>
      <ID>
        <Maker maxbyte="1" offset="0x00">0x98</Maker>
        <Device maxbyte="1">
          <DevId offset="0x01">0xD3</DevId>
        </Device>
      </ID>
      <Size unit="mbit">8192</Size>
      <Sector uniform="true" secure="false">
        <MaxSector>4096</MaxSector>
        <Size unit="kbyte">256</Size>
      </Sector>
    </Flash>

    But thank you for answer!

    It's probably a Samsung Flash chip, but set to bad Flash by the VU+ driver attack. Manufacturer replaced the Samsung chips by Toshiba chips when this happened.

    Or, if you want to know for sure which nand chip it has, you will have to remove the sticker.
    With a bit of luck and warming up the sticker, it might be possible to remove it completely so that you can reuse it.

    Another option is to measure the eight I/O pins, and see if they are all in the same ohms range because it may also be that the nand flash chip has some bad I/O pin connection to and from the cpu.
    Measure them between a ground spot, and the pins by ohms.

    But also, it may also possible that the nand chip is defective, a new one may solve this issue.
