K2硬改16M+128M，从半砖到彻底失败。

zhao20946

经常在论坛里看各种硬改的贴子，自认为可以实践了，就拿出被淘汰的K2试手。

一路状况不断，最后以翻车告终。过程给大家分享下，也希望有大佬指点下。。。

1、先拆下原机8M闪存，用编程器读出原固件（原系统breed+高恪），然后写入新的华邦16M闪存并装入机器上，按reset通电并成功进入breed。

2、断电后，用风枪吹下原机64M内存，然后装上华邦128M内存，按reset通电进入breed。

3、进入breed页面，上传固件进度到一半的时候中断，breed也进不去了；再次尝试进入breed，ping 192.168.1.1 -t，发现ping通几下就断开连不上了，重复几次操作都是如此。

4、breed能短暂进几秒，发现闪存和内存都能识别。先从软件上找问题，挑容易的下手，拆下闪存重新写入最新的breed并焊回去，问题依旧。

5、焊好排针连TTL，TTL有输出，但是TTL显示了几次信息后，没什么别的操作就彻底砖了，再开机进不了breed也无TTL输出，输出信息如下：

能换内存，手艺不错啊

yxb007

你这个应该是内存没焊接好，再吹吹，或者拿下来重新值锡

也是第一次换，莫名其妙的就砖了，硬砖估计救不活了

内存虚焊的可能性很大

没有换内存技术就不要换，

内存没焊好，重新拆下来植锡

天明夜暗

再吹一下，吹到镊子碰一下芯片能动，会自动复位，那就好了

三楼正解，应该是内存虚焊造成的

可能是虚焊然后脱焊，就彻底不能开机了吧。晚上回去再吹下试试，也可能是内存有问题。。。
