How to disable flash drive protection?

Question

USB flash drives

SanDisk flash drive is write protected how can I disable protection

Answer 1

Check the flash drive in R.tester: https://rlab.ru/tools/rtester.html
If it somehow identifies it - volume, vendor, etc., then write what and how, then you need to start from the specifics.
If you need files from a flash drive, and it is not detected in R.tester, then alas. There is nothing to be done at home, choose a data recovery specialist in your region: https://xn----7sbbfbnfa0a2audfacc2cat8e9f.xn--p1ai/
If you don’t need information from a flash drive, then the best option is to exchange it under warranty. A drive that once failed is no longer reliable.
Trying to restore her performance is unreasonable, she will let you down again, and according to Murphy's law, most likely at the most inopportune moment.
UPD:
In addition, technological utilities are recommended to you in the neighborhood. In no case do not use them if you need files. After them, no data can be recovered.

Answer 2

Look for your flash drive at https://flashboot.ru/iflash/ , see what utilities are suitable for it. Try low-level formatting or controller firmware if you can find a flasher and firmware with the right combination of controller and flash memory.
But most likely the flash drive is hardware broken and there is no point in dealing with it.
