It was the same. Despite the fact that the screen flickers, the program flashes the book. Click first on the Switch, and then on Update. I poured out the same way on 3 firmware from the official site. In short, while the update did not go away completely, I sat and ran the firmware again and again.

Everything, hang up, the problem is solved. It turns out that you need to pull the lock lever back and forth, otherwise it does not want to flash the infection. AT)

There was such a problem, on my Rhythm-420, for some reason, the name of the folders with the books, and the files themselves, stopped being read. Shows some squares. Tried to delete, not deleted. I made the firmware from the official site, everything remained as well. Is it even possible to format the built-in memory card and write to it on a new one?

Look in the language settings of the book installed language. Obviously not Russian.

Disassembly of the E-book Ritmix RBK-420.
1. Take out the rubber plugs with a sharp tool and unscrew 4 screws (black) with a screwdriver No. 0.

2. Blade we separate the case from the side of the connectors, and on the right and left side. We separate the top last, because the cover is glued on the tape to the battery

on the edges to the left and from the right by 3 latches, and on the top and bottom two.

3. Gently lift the lid, a speaker is installed on it, it is soldered to the board, we unplug the speaker and the battery. We take out the screen connector.
4. Unscrew 4 screws (white) and remove the board.
5. Reassemble in the reverse order.

Is it worth it to flash it on a newer firmware, and does the format read from you FB2 ???

When updating the firmware (set v2.2.4 for Texet TB-720HD)


And what program was used for firmware? Native or also from texet?

I want to share the solution to the problem with the "update library" sticky window. All actions were carried out according to the instructions for the firmware with some additional steps.
IMPORTANT! All actions were performed on Windows 7 x86, drivers were not installed on Windows 7 x64.
1. Download the firmware and firmware from the off site (http://www.ritmixrussia.ru/products/rbk-420).
2. Unpack everything and run RK28Upgrade.exe on behalf of the administrator.
3. We connect the device to the computer. A message like "Found RK28 MSC Device" should appear in the status line of the program.
4. Select the firmware file by clicking the "..." button where it says "Image Path:".
5. Click the "Switch" button, after which the system will try to install the driver and therefore will not be able to. Start the "Device Manager", find an unknown device there and install the driver manually. Driver included with the program.
6. (Optional) click the "Get Disk Size" button. A window will appear with information about the size of the memory. I did this purely to test the responsiveness of the device.
7. Click "EraseIDB". As far as I understood this type as deleting a partition on the hard drive.
8. Click "Upgrade".
9. At the end of the firmware update, turn off the device. Close the program. We connect the device to the computer and try to enter the disk of the internal memory of the device and receive a message stating that it would not hurt to start formatting it. We agree and format with the default settings.

The whole device works again.

P.S. Is it possible to do "EraseIDB" without flashing I do not know. And I do not recommend experimenting.

Some of my observations about the firmware:

1. Firmware from 12/14/2011 works best (tyk).
1.1 In the latest version (dated 06.03.2012), the video often hangs up, or the video is played only until a certain moment. This was not related to the limitations of the FAT32 file system on files up to 4 GB in size. The reasons are most likely in the most prosh.
1.2 In the very first version of the firmware (dated 09/20/2011) there were glitches with the interface - a frigid pink background in the status bar when playing video, not typical for other firmware brakes when playing video. And also guaranteed to give Error (-9) (see spoiler, because I haven’t saved the error log, I brazenly took it from the user's messagekoren2003)
INFO: Test Device Start
INFO: Test Device OK
INFO: Download IDB Start
INFO: Download IDB OK
INFO: Reset Device Start
INFO: Reset Device OK
INFO: Test Device Start
INFO: Test Device OK
INFO: Download Image Start
INFO: Write image to flash, Image Size: 99328K, Written: 99328K
INFO: Check image, Total: 99328K, Checked: 43008K
INFO: TestUnitReady ok
ERROR: Download Image Fail,Error (-9)
INFO: Upgrade End

2. Alas, none of the firmware correctly works with NTFS.

3. Do not run the program for firmware in compatibility mode with Windows XP on Windows 7 (and, presumably, at 8) otherwise it will not be able to put the device into bootloader mode.


And so if to sum up, then it would be necessary to successfully flash on Windows 7 x86:
1. Please download from 12/14/2011
2. Run the "flasher" on behalf of the administrator (mandatory) but NOT USING any compatibility mode.
3. Refer to the post comradeBl @ ckmor (tyk), for he described the installation process in detail.

IMPORTANT! All actions were performed on Windows 7 x86, drivers were not installed on Windows 7 x64.

1. I personally checked on a laptop with Win7 x64. The drivers did not get up from the win7 folder, wrote the error code 10, but from the "vista" folder they got up fine.
2. And one more note: - USB 3.0 was not detected, it was defined only in USB 2.0.

For the rest, while I am observing ...
