In fact, users in China use the U8800, multi-system has been used for a long time.
So, now I will use my broken English to tell you how to use multi-system
First, you need The extra two partitions in the 4G space
. you could use twosys-partition.zip to get The extra two partitions 15&16
download partition package:http://forum.xda-developers.com/atta...1&d=1321675310
The second system-specific recovery system
put the twosys-partition.zip and you like rom's zip into Sdcard
rename the recovery_22.214.171.124_en_sys2.img to recovery2.img , then place it to /cust
Boot into recovery,flash this package directly, same as flashing a ROM.
After flashing go to advanced options, choose to reboot to recovery.
Go into recovery again, flash this package again directly, same as flashing a ROM.now you will have The extra two partition 15 and 16
OK, let's flash two system into you phone
Go into recovery again, flash you like rom's zip
boot into first system, you could use RootExplorer access /cust, rename the recovery.img to recovery1.img, rename the boot.img to boot1.img,rename the recovery2.img to recovery.img.
reboot you system into recovery, now you recovery is second system recovery,you could flash the 100911-cm7,it will auto flash into second system.
reboot system, you will into second system (CM7)
if you want change you system to first, you could use RootExplorer access /sbin/gk, you will found some .sh files,Execution the 8-ChangeSys will auto rename all
img file then auto reboot to first system.
you could copy the 8-changesys.sh to any place let you change system easy.
restore offical partition ： download
：only the 100911-CM7 can flash into second system, other ROM only flash into first system
please backup your data, because you will lost all data in phone
