我的ipaq hx2110是英文版的，装了中文输入法后没有配置好，系统几乎崩溃，无法使用，就想升级到WM6看看。从网上找到的升级教程，应该是一个俄罗斯的大牛搞出来的，从下载来的升级包中可以看到很多俄文，这个升级过程需要使用不同的nbf文件来回刷机三次，才能进入WM6，时间有点漫长，不过总算顺利。
1) Hard reset iPaq. Do this by holding the calendar button and itask button (curved arrow), and then put your stylus into the reset hole on the bottom of the iPaq. This will hard reset it.
2) After doing that, put it in to bootloader mode. You do this by holding the contact button (to the right of the calendar) and the itask arrow, and then clicking the reset button on the bottom. It should now be in bootloader mode. unplug the power/usb cable and plug it back in. hit the calendar button. it should now say USB.
3) run hpRUU.exe under the Wm5.0 for hx2000_1.00.00.L_ENG folder. It's found in provishki. it will flash your ipaq to 1.00.00.l . let it flash all the way.
4) hard reset the ipaq and put it in bootloader mode. see steps 1 and 2. make sure it says USB.
5) do step 3 again, but this time don't click upgrade. rename the E1_Upgrade_ROM_v1_00_00_L_SIGNED.nbf file to 100l.nbf
重复第3步，这里一定要注意操作顺序，先点出hpRUU.exe，等检测到PDA之后，upgrade按钮出来之后，再重命名E1_Upgrade_ROM_v1_00_00_L_SIGNED.nbf file 为 100l.nbf，我第一次升级时，没有注意顺序，先重命名文件，再运行hpRUU.exe结果hpRUU说我的sku号码不对，不能升级。
6) go into the SP32408_1.00.00.H_ENG folder and get the NBF file from there. copy it into the 1.00.00.L folder that we were just in. rename is to E1_Upgrade_ROM_v1_00_00_L_SIGNED.nbf. click upgrade. let the upgrade finish.
进入SP32408_1.00.00.H_ENG 文件夹，将NBF文件拷贝到
7) repeat steps 1 and 2.
8) delete the E1_Upgrade_ROM_v1_00_00_L_SIGNED.nbf file that you just copied over and rename the 100l.nbf file to E1_Upgrade_ROM_v1_00_00_L_SIGNED.nbf.
9) run hpruu.exe again. DO NOT CLICK UPGRADE.
10) get the wm6_wwe.nbf file and copy it into the directory we were just in. rename E1_Upgrade_ROM_v1_00_00_L_SIGNED.nbf to 100l.old and wm6_wwe.nbf to E1_Upgrade_ROM_v1_00_00_L_SIGNED.nbf
11) click upgrade. let it finish.
12) repeat step 1
you should now have Windows Mobile 6 on your iPaq. Good luck
附带我的ipaq截图：
原始升级包下载比较麻烦，有200多M，但实际上针对hx2110有很多文件用不到，我就做了些精简，重新打了一个包，只有90多M。
