RESTORATION OF THE DEVICE FOR RK3188 / PX3 / RK3368 / PX5

Recommended for those who do not have an OTG port and mechanical buttons

(responsibility for the consequences lies with you)

Download the archive, unpack it in any folder (it is desirable that in the way there were no spaces and Russian letters).

Attached fileSD_Firmware_Tool.zip (489,51 KB)

The program SD_Firmware_Tool.exe is in the archive . With its help we will prepare a loading card.

We also need:

1) PC running Windows, having a card reader

2) microSD card for 2 - 4 GB (in the process of working all the data on it will be erased).

3) firmware (file update.img or dupdate.img ), compatible with the processor and the screen resolution of your GU. It is desirable - the same one that was on the device before "zakirpichivaniya."

Procedure:

1) We insert the card into the card reader PC

2) Run the program SD_Firmware_Tool.exe

3) In the top drop-down list "First: Choose removable disk" select the drive letter corresponding to the card.

4) Below put the flag "Upgrade Firmware".

5) Click the "Firmware" button and select our firmware update.img ( dupdate.img ).

6) Click the "Create" button and wait for the process to finish.

7) Close the program and look at the map. The files rksdfw.tag , sd_boot_config , sdupdate.img appear on the memory card.

8) We completely disconnect the power to the radio. That is, turn off even the wire BAT (yellow), not to mention ACC (red). It is best to just pull out the main connector on the back.

9) Insert the card into the "GPS" jack of the radio.

10) Turn on the radio, immediately feeding it full power, that is, both from the battery and from the ACC (as a working option - pre-turn in the car ACC, and then connect to the radio main connector).

11) We are waiting for a few seconds and do not worry.

12) The sign of success will be a lot of text messages on a black background, similar to what we see during normal firmware.

13) At the end of the process, the message "All complete successful! Please remove the sd-card." Appears at the very bottom. (orthography and punctuation of the original).

14) We take out the card and wait for the radio to load. If the recorder does not reboot itself after removing the card, then "help" it by pressing the Reset button. If the screen is not lit,

Everything - the process is over.

What to do with the card? The fact is that the program has formatted it in a special way, and in Windows you now see its incomplete volume. And in the radio tape recorder it can not be used at all - otherwise automatic flashing will take place every time it is turned on.

The card can be returned to the normal format using the same program by clicking the "Restore" button. Or save this card as a tool to restore the radio.

PS In some situations (there is a suspicion that this happens when trying to upgrade to firmware with another partition markup), the above method fails. Namely: after the start with the boot card at the bottom of the screen, an error message appears immediately after the start of the process, accompanied by a recommendation to remove the card. After removing the card, the system remains in the recovery mode. Further attempts to execute the item (s) of the menu, assuming the installation of the firmware from the card, fail with the message that there is no firmware file on the card. This happens even if you insert the card back. This is due to the fact that the card was removed, and its re-mounting is possible only after a reboot. But if we (with a newly inserted card) select a restart in the menu, then the start will happen again from this boot card, again there will be an error and so on in a circle. And if we insert another card, then instead of recovery, the main loader will start, and since the system is "corrupted", there will be a hangup.

In this situation, you need to store a USB flash drive (or another card inserted into the USB-card reader - it's also perceived by the tape recorder as a USB flash drive), in addition to the boot card, to write the firmware file (update.img, dupdate.img or nupdate .img - depending on the hardware and software "subspecies" of your radio), and then insert this USB flash drive into the USB jack of the radio. And now after an unsuccessful start from the card and the recovery menu appears on the screen, we just select the item "update from USB", well, then everything is as usual.
