本文提供了解决平板电脑遇到的无法升级内核NAND问题的具体步骤。包括使用正确的固件文件、创建定制的microSD卡以及利用特定工具进行修复等方法。通过两种不同的修复方案（FIX#1和FIX#2），帮助用户克服这一难题。
There are now two possible fixes for the cannot upgrade kernal nand issue. The latest nand chips may need to use the FIX#2 instead of the FIX#1.
1) Create an uberoid rom micro sd card as you normally would.
2) Since most users with these issues probably do not have a backup of their original env_uboot file, so choosing a correct option in the changer will still be somewhat of trial and error.
3) Format your sd card using fat32 full format
4) Download the uberoid rom to you pc and using 7-zip extract the rom to a location on your hard drive
5) navigate to the folder where you extracted the rom too
6) run changer.bat
7) choose the selection that best fits your table model #
8) if the changer ask to format the sd card answer no (you have already done it I hope)
9) if the changer asks to copy to sd card answer yes
10) Download the following file at :
FIX#1 http://www.4shared.com/file/obPwUPVj/uzImage.html OR
FIX#2 http://www.4shared.com/file/hCrsXM3v/uzImage.html
10b. copy this download file to: /firmwareinstall folder on the sd card. Windows should prompt for overwrite answer yes
11) Safely remove the sd card from the pc and flash as normal.
Again allow 15 minutes for first boot after flash and selecting proper option will still be a trial and error. But this should overcome the cannot upgrade kernal nand. Should you need to use another option in the changer you will need to repeat step 10b after the new sd card is created ..
FIX#1 was provided by user db8200 who obtained an updated rom from his seller. He discovered differences in two files, the u-boot.bin and uzimage.bin. Please pass on your thanks to db8200
FIX#2 was provided by user njkane1979 who obtained an updted rom from hisseller. We need some additional testers with this new generation of nand flashes to see if the issue is resolved ..
Pass on your THANKS to user njkane1979 ..
This fix was verified by user Perfekt who successfully updated his tab that was also experiencing the cannot update kernal nand error. I am pleased to report he now has a fully functional tab. Please pass on your Thanks to Perfekt.
