Kingston 8G USB drive, Phison PS2251 39 main controller, mass production can not recognize 8G

This means that your USB flash drive is likely to be expanded from 4GB to 8GB. 4GB If you force him to change it to 8GB, then the U disk will have a reading and writing error after a period of time, or how big it is, or find a seller If it is within the warranty period, U disk parallel goods, there are many fakes, and you must buy it through regular channels when you buy it. good luck！

What else can I say, fake, with a capacity of only 4G

Try using a different mass production tool.

There are a lot of counterfeit USB flash drives in Kingston, and many of them will have problems after a period of time, such as being written protected and not being able to display data.

Hello, this means that the main control does not correspond, try to change to other versions of the tool.

Mass production is risky and may damage the USB flash drive ,..The mass-produced USB flash drive should be a genuine product of a big brand.

Mass production method: 1. Use the U disk *** main control chip identification tool chipgenius or chipeasy chip to find out yours without worry"Chip manufacturers"、"Chip model", two parameters. Search the Internet for the corresponding mass production software.

2. Because there is no universal USB flash drive mass production method, search the Internet for the use of the corresponding mass production software.

The next latest chipgenius or chipeasy chip worry-free test is not available"Chip manufacturers"、"Chip model"parameters, it should not be mass-produced. And there is no corresponding mass production software success case teaching on the Internet (guinea pig) should not be mass produced,

Hello, this is a U disk mass production tool, don't recognize or make a mistake, you can use other versions of Phison 2250, re-mass production, there is no other way, if mass production can't be done, only throw it away.

I don't even recognize my own mass production tools, or the USB flash drive that can't be handled, has been so bad that even the USB flash drive manufacturer has to discard it.

USB drive is damaged and larger, replace it.

Pure originality, even if it is copied, it is copied by itself.

There is a risk in mass production, and the ,.. of the USB flash drive may be damaged by the wrong tool, wrong method, and wrong operationThe mass-produced USB flash drive should be a genuine product of a big brand.

If you can't recognize the U disk, maybe the U disk memory card is broken, go to the after-sales service to replace or repair, and you don't have to look at it below.

If you can recognize the U disk, you can try the next method, if you don't care about the data, try it first:

!!If you only recover a USB flash drive memory card, there are several more common methods, and if one does not work, change the other.

1. Use ufoamat or fill 0, fill 1, and then format to try to see carefully, don't click the wrong plate.

2. Use diskgenius to forcibly format and try it (it may affect future mass production).

3. Use hddllftool to forcibly lower the level, 4. Use diskgenius to repair bad roads (bad blocks), and purely personal success has been done with this, (forcibly repaired).

What should I do if the computer does not recognize the USB flash drive.

2. There should be something online. If not, it should be that the mass production tools have not yet flowed out. You have to wait for it to leak out.

In this case, there is only one way to shorten the chip needle angle. Note: Be sure not to short the wrong connection, otherwise the chip will burn off. You'll have to go and get a new one.

Re-production, pay attention to the original firmware. It is unlikely that a USB flash drive can be found, but it cannot be mass-produced. Use tweezers to short-circuit, and when the mass production tool is found, let go of the tweezers and mass production.

You're awesome, re-test it with the chip wizard.

Smash it and buy a new one. USB flash drive is not expensive. You don't have important information anyway.

Let me tell you, I'm a mass-produced USB flash drive! Listen to the landlord: If you don't have important data in it, it's too easy to do (it doesn't look like it, because you've been brushing for a long time), I'll tell you a 9 yuan solution, PS2250 is unstable, even if you brush it, there will often be problems.

You go to the electronics mall to find the 6280 chip of the U disk board (just the board of the flash memory), there is, quite stable, and it only takes two minutes to brush the firmware 8G, and the upgrade program is also given, I have these, but the mail plus the postage is not suitable for you, just buy it, (don't brush the ps2250 again, the main control has bad feet before you can brush in) use the cutter head chrome iron to slip down the flash memory, perm back and forth a few times, while scalding with fingernails, after lifting this end and that end, it will come down (we all keep the nails), and then weld on the new board, It is good to pay attention to the identification point of 1 foot, and the welding leg is not afraid, and it will be opened after a few slips, and then the firmware will be brushed, ok, 8G has become.

You can contact me to help you solve it, after the short circuit is repaired, you need to re-flash the firmware to recover.

The landlord is not too divided, and he sent two of the same and 100. What are the consequences of mass production failure? Is it a flash hanging? Try again with a different tool version (I think the two versions of mpall and mpall are good), and flash the firmware again.

It is more useful to ask for help on the digital home than to send it here, where there are many masters.

Continue to look for mass production tools that can recognize your USB flash drive, and continue to toss.

The last time I had Kingston 16G, it seems to be PS2251-68, and I can use it again after many attempts!
