最近uvk6出了个多固件切换，我刷上了losehu 129h，losehu129e，原厂固件以及cec3.0v。在刷完固件切换过一次之后就不能再次切换了，在萝狮虎的github上有个添加80B代码段，这个要怎么添加到固件上，要用什么修改[upl-image-preview url=https://storage.hamcq.cn/2024-07-09/1720545089-491554-img-20240710-011005.jpg]

@"BI1TPU"#p22834 我有个没扩容的，问客服是多大的说是1M的，我强刷扩容固件刷成雪花屏了，给救回来了

@"BD3PVM"#p22845 我现在只能用自定义固件129

似乎就是要4M才可以刷，之前想搞多固件切换，不过看到要拆机烧录望而却步，之前在b站上刷到一个视频，希望能有帮助。【泉盛UVK5/K6 多固件引导刷机演示-哔哩哔哩】 https://b23.tv/kTGjdFu

原理上就是利用第二块EEPROM存储多系统，如果没有扩容4MB是无法正常存储多系统的

@"BD3PVM"#p22845 你这个事因为没有刷汉子库的原因吧

@"BD3PVM"#p22845 1M版本可刷LOSEHU132固件，132H等带后缀的版本空间才不够

@"BA8AMF"#p78170 是的，后来看到萝狮虎发了视频教程，需要烧录就没有继续搞了，手里是有一个4m版的

现在的多系统切换不需要固件兼容，不存在80B代码段。

Regarding UVK6 firmware modifications

BD3PVM

I recently upgraded my UVK6 with the Losehu 129h and 129e firmware, as well as the original factory firmware and CEC3.0v. However, after switching between these firmwares once, I can no longer switch back. There's a 80B code snippet on GitHub from LösseTiger that I want to add to the firmware. How do I add this code? What modifications are required?

BI1TPU

My K6 regular version has been bricked.

BD3PVM

BI1TPU I have one that didn't get expanded, and when I asked customer service what size it was, they said it was 1M. I then forcibly flashed the expansion firmware, which turned it into a Snow Flower screen, but I managed to recover it.

BI1TPU

BD3PVM Currently, I can only use custom firmware version 129.

BD3PVM This issue might be caused by the lack of updating the "Hanzi" library.

Charactex

BD3PVM The 1M version can only be flashed with firmware for the LOSEHU132 and 132H versions (with suffixes), but not the versions with more space.

BA8AMF

It seems like you need at least 4M to flash. I was planning on switching between multiple firmware versions, but after seeing that it requires disassembling and reflashing, I decided against it. I saw a video on Bilibili that might be helpful. [QuanSheng UVK5/K6 Multi-Firmware Flashing Demonstration - Bilibili] https://b23.tv/kTGjdFu

BD3PVM

BA8AMF Yes, later I saw a video tutorial from Luo Shi Hu, and since it required burning, I stopped trying to do it myself. I already had a 4m version.

Charactex

The principle involves using a second EEPROM to store multiple systems. Without expanding the storage to 4MB, it is impossible to store multiple systems normally.

SilentYANG

Currently, switching between multiple systems does not require firmware compatibility and there are no 80-byte code segments involved.
