转自xda,本人没试过,不对结果负责,呵呵
首先,只有使用aio刷破解版的4.0的,才能回去,
如果你直接在线升的4.0,对不起,回去等完全破解4.0吧
1,重启,进入RECOVERY模式(音量+和电源键)
2,刷3.2.1r2的文件,这就是卡刷,先下载rom到外置sd卡上,现在中国的rom官方还能下到
http://info.update.sony.net/ST005/nbx03_024/contents/0008/signed-nbx03_024-ota-0042.008.zip
3,在刷的过程中平板将会自动重启3或4次,此期间显示的是机器人下面三个点的界面
在第三个点变绿之后重启时,按住音量+键
这样你就能在完成前回到RECOVERY模式,这非常重要
4,抹除个人数据
5,完成
最后的抹除也是很重要的,因为你不这样做的话,就会死到启动动画那里, 再启动的话将会启动到冰激凌三明治了4.0只有抹除才能正常启动所以如果你在卡刷完不抹除,就得重头再做一次了.
原文:
Can I downgrade my device from prerooted 4.03 to 3.2.1r2?
- YES! In few simple steps:
1. Boot into RECOVERY;
2. Flash 3.2.1r2 update zip (removed from s.ony server - added mirror);
3. During flash tablet will reboot 3 or 4 times, with 'green dots' screen.
Just before last 3rd dot reboot you've got to hold VOL+ button,
to get to RECOVERY just after flashing complete! IMPORTANT!;
4. Wipe device;
5. DONE.
Wipe just after flash is very important, because if you will not gonna do this,
then it will be bootlooped in start animation, after wipe will boot correctly,
but after another reboot it will gonna boot again into ICS!
So if you will not gonna wipe just after flash, then just start all over again.
