The versions earlier than dfu 3.26 is applicable to lcd7781. It works this way.
The versions later, however, is applicable to lcd 9341. If you reinstall the system with benf firmware or other old firmware, there will be such a device error as white screen because the driver for lcd is different. You need to reinstall the system with new firmware.

This only works when your device is with versions earlier than dfu326. Because the wrong lcd driver will lead to white screen and program running failure. However, the way this fella did is awesome!

Will the source code for 201 be offered to the fans for re-development? If it will, would you pleasure share with me where I can get it? If not, the period for the re-development would be lengthy?

If I modify the stuff like you did, how can I retrieve the saved files? Is the disk catalog visible if I insert the original Mini USB? Or, the saved files can not be retrieved if I don’t add the SD card to the card reader, right?

It’s dope! In fact, you may use microSD transformation card (SD) to do it. (Please check if the connection position is matched)
The plus for this transformation card lies in that you can change MicroSD Card by extraction and replacement.
PS: you can see the saved content in this card when you connect it with pc. It is really an advisable way to modify your device.

The benf here is easier to operate. It is way better than that from the original factory. It’s really cool!

To implement the change of TF card, TF card is under 2g, and is the old type of  card (about 3, 4 years ago), because the new communication protocol of TF card changed, was put to also can't identify the NANO, so don't recommend this operation You only put the flash chip welding back.
