How to remove write protection from a QUMO flash drive without formatting?

Question

USB flash drives

About two weeks ago, as a result of a hardware glitch, part of the data stopped being read from the flash drive. The flash drive itself is correctly detected by the system, the FAT32 file system (it did not fall into RAW), the total volume of the drive and the amount of occupied space have not changed, i.e. like everything is in place. But here's the trouble - when you try to open some of the folders, a warning about CRC arrives, i.e. even just to open and view the contents of these folders is impossible. I tried to pull out the data with recovery programs - it pulls out exactly what I see, i.e. no result. At the same time, in disk management, the flash drive is defined as read-only. Help with advice on what to do next - I don’t consider formatting, I need to pull out the data. Already went through all the options (registry, diskpart) - does not help.

Alas, I think I'm hint000right.
In short, you are in Moscow, we will be happy to help with a flash drive: https://rlab.ru/flashrecovery/
What you can try yourself:
Download R.tester and run a reading test. It will either break, or you will see exactly where and how many unreadable sectors there are. If you read everything, see the next step.
You can also skip the previous step and try making a binary uncompressed disk image right away (GNU ddrescue, Clonezilla, etc.). If it suddenly turns out that the entire drive is readable, then it would be useful to correctly extract it, insert it, make the full image again (into another file), and then compare the two images byte by byte.
It is highly likely that there will either be places where the data differs, or there will be zeros (or FF FF FF) where there shouldn't be. These are the problem areas.
After that, open the image in the old version of R.saver (it can work with images) and do a full scan.

But in general, I think that this is all a dead poultice and the result will be the same.
You need to contact a company that deals only with data recovery and nothing else, because. the problem is hardware and requires special equipment and knowledge. Various "repairmen" will not be able to do more than yours. Well, if they don't hurt.
If you are in Moscow, please contact, if not, here is a brief reminder of how not to get into a scam: data-recovery.rf
PS
A small but important addition: if the files are really needed, it is better not to delay. Now flash memory is very crappy (you can see it for yourself), and after just a few months on the shelf, all the data can be covered with "holes" (gaps) due to charge leakage in the cells. We've been seeing this on a regular basis lately.
The more modern the flash drive, the more relevant it is.
And in no case use technological repair utilities selected by VID / PID. Their purpose is just the opposite, and after them it will be impossible to restore anything at all.

Remove a disk dump from it, and you can already open it for writing and repair the file system
