大佬，这个固件更新了啥

@"BI4PMQ"#p31614 官网给出的是： 1. 更改为显示 VFO/PMS 扫描期间的频率（最高 100kHz）。我试了一下VFO扫描已改成100kHz步进了！ 2. 进行了其他功能改进和优化。暂时还没有发现！

数据线需要单独买么能用K6的吗

@"BG4ILW"#p31628 记得5D附带了一根Mini USB线，可以找找包装盒里面。实在不行就只能花高价买那个专用接口的线，或者单买接口做一根。

谢谢，没想到5DR现在还在更新固件~

@"BG4ILW"#p31628 八重洲中国官网给出的升级手册PDF版本真的是缩水太多了，我翻译了日本官网的升级手册，升级需要原装的USB线，类似于选装的SCU-19等等是不可以用于固件更新的，不过您可以试一试！

@"BD8DLV"#p31656 中国朋友选购5DR太少了，不过在国外还是很多的，就像我发这条固件升级的贴子一样，全网都找不到，只能自己摸索，官网给到的信息量太少！

@"BD8DLV"#p31656 这好歹是八重洲最新的旗舰手台，还能不给固件了啊🤣

@"BI1ULP"#p31658 难怪，我用咸鱼上淘的写频线没办法升级固件。

@"BI4PMQ"#p31673 😋因为我想到21年的手机24年可能都很少给系统升级，所以以为5DR的固件已经很稳定了

Yaesu FT5DR upgraded to the latest firmware; a novice user experienced many difficulties, but ultimately succeeded!

BD8DLV Received, thank you.

bigQ

BD8DLV I feel that Xiaomi's phones have the best battery management... The battery management is excellent, and charging is also very fast.

BD8DLV

bigQ Perhaps this is due to Xiaomi's internet-centric company culture.

BloodBlade

BD8DLV If accessed via a mobile device, it displays betting website advertisements. It's likely that the site has been compromised and hasn't been patched yet.

BI4PMQ

BloodBlade Is it still visible? I already found it before.

BI1TSS

I just upgraded the firmware for my 500DR yesterday and it worked perfectly using an SD card.

BG6QMO

After upgrading, an error message appears.

YAOQI

BG6QMO The error message was unclear, which scared me and made me hesitant to upgrade for a few days.

BloodBlade

BG6QMO Try re-entering DFU mode and uploading the firmware again. If that doesn't work, you may need to contact customer support.
Remember to check the version on the packaging box before you start, as the link provided by the original poster only applies to packaging boxes with a region code of.CHNthe devices.

BloodBlade

BG6QMO Another possibility is that there's a configuration issue. If you have a serial cable, try re-entering the frequency settings first.

BH3QBH

BG6QMO 我也出现了报错，去英文的那个官网下载EXP版本的，刷上就好，我的弄好了

BH3QBH

BH3QBH After the upgrade, it started giving errors and wouldn't boot. I have re-flashed both the primary and secondary programs, and the display indicates that the flashing was successful, but when I try to boot, it fails. I have tried flashing multiple times, but it still doesn't work.

YAOQI

BH3QBH Is this going to require a warranty claim?

BI1ULP

BH3QBH Based on your question, I found the reason for the problem on Facebook. There are many versions of the 5DR available globally, and for the Chinese version, the firmware cannot be downloaded from the Japanese website and should not be referenced against the upgrade instructions from the Japanese website! I have tried multiple times, and the issue is the same as what is reported on Facebook. I hope this can help you resolve the problem!

Therefore, I recommend downloading the firmware update from the official Yaesu China website at http://www.Yaesu.com.cn/down/class/?2.html!

YAOQI

BH3QBH I'm so worried that I can't bring myself to update the firmware today.

BI1ULP

BH3QBH The problem must be with the firmware upgrade package I downloaded!
After unzipping, the main component should be at the very end and in uppercase.（CHN）Exactly!

BH3QBH

YAOQI 我都发走了，售后打电话，告诉我英文官网下载了就可以了

BI1ULP

YAOQI Be a little bolder! Haha!

BH3QBH

BI1ULP 不对，我就是下载了CHN的版本才报错，后来英文官网下载了EXP就好了

YAOQI

BI1ULP Try upgrading now.

BI1ULP

YAOQI I tried clicking the link, but I couldn't get to it. However, when I searched for "Yaesu China official website" on Baidu, I was able to access it. The links are identical, with no differences in spelling or characters. I don't know if Yaesu has blocked some functionality on the HamCQ website. Haha, who knows!

YAOQI

BI1ULP Thank you, sir.
