I am anticipating that some of you new 770C (8740) owners have not tried to upgrade firmware on any of the Xuelin players before. I am, therefore, posting here the instructions for this process. I hope these instructions are simple and clear enough to get you thru the process. Please let me know if you have any questions... Good luck, and remember, if you don't like the new firmware, Xuelin has included the original firmware in this download, so you can always put it back on your player. But AGAIN, this firmware is only for the new 770C (8740) and not the original 770C (8718).
Instructions for updating firmware on the Xuelin 770C
First, you will need access to a computer with Windows 7, XP or Vista. I have not been able to get a computer with Windows 8 to complete this process. You can use either 32 or 64 bit Windows 7. I have had problems with some newer computers due to some of the newer processors. I am using a Dell computer with Windows 7 (64 bit). I have the Intel Core 2 duo on my laptop. I have been able to use an older Lenovo laptop with Windows 7 that had one of the early versions of the i5 processor, but I have not had luck with newer Lenovo laptops with newer versions of the i5 or i7 processors…
Download the file that I’ve linked to above (post #640 in this thread), this will give you a file named “ihifiupimg-new770.rar”. Once you have downloaded this file, then open it. Before you can update the firmware on your 770C, you will need to download the drivers you need to your computer; this is very easy. After you have opened ihifiupimg, you will see a subfile named “Release_DriverAssistant”. Click on this to open. You will see another file named “Release_DriverAssistant”. Click on this file to open. Go down to subfile named “DriverInstall.exe”; click on this file and an image will appear (RK driver assistant). Select “Install driver”; you will soon see an image that asks if you want to install this device software; select install again. Depending on the speed of your computer, you may see this message again, just select install again. After several seconds to a few minutes, you will get a message that says drivers have been installed ok.
Once you have loaded the drivers, go back to the main ihifiupimg-new file. Look for the subfile named “RK27Image_upgrade.exe”. For some people with Windows 7, you will need to run this subfile as administrator to complete the upgrade process. For others with Windows 7, you may only need to click on this subfile and it will extract to your computer; the upgrade image will appear on your screen. When the image appears, look at the text box at the lower left corner of the image; it will have some symbols in it that contain …RK27…. You then want to connect your 770C to your computer with its usb cable. After you connect your 770C, select usb on the DAP and the image will change to “iHIFI usb connection” on the DAP screen. The text box in the left lower corner of the upgrade image will now read something like …RK27 MSC…
Now look up to the top 1/3 of the upgrade image and you will see a box that has the number “80” in it. Just to the right of this number 80 box, you will see a row of 4 “buttons”. Go to the second button (the one that reads something like E>>>>). Click on this button. The message in the left lower text box should change to …RK27 Loader… Next you will look back up to the number 80 box. Under the row of the “4 buttons”, there is a text box that is labeled “Image” on its left side. Go to the right side of this image text box and click on the button (…). An image will appear and this is where you will open the firmware for the 770C (n770new.img); the n770new.img is found in a subfile of the ihifiupimg-new770; the subfile is “img”. Double click on this subfile and 2 image files appear. As you would expect, the n770new.img is the new firmware upgrade. The n770old.img is the firmware currently on the 770C (8740). (for better access to the n770new.img file, I have downloaded the image file to a separate flash drive. I plug the flash drive to a separate usb port on my laptop and select the image from my flash drive).
After the image file appears in the “file name” box, then select open. The number box that read “80”, should now read “688135”. Next click on the 1st button just to the right of this “688135” box. After you do this, you will see several lines of text appear in the large text box in the middle of the upgrade image. Once the firmware has been added to your 770C, the DAP will turn off briefly, but then restart. Occasionally, the 770C will appear frozen after the firmware change; if this happens, you will need to reset the player thru the small hole (with a paper clip) under the microsd slot.
Since this is the Chinese version, the language on the player will be in Chinese. If you wish to change the language on the DAP, scroll down to line 10 on the screen (first line is line 1). Press the select/play button and another screen will appear with 1 line. Press select/play again and the language options will appear. Move to the language you prefer, press the select button and the red check mark will move to that line. Then press the return button on the DAP to move back out to the main menu.
