一般情况下进行OTA升级，是不会清除用户数据，如果想清除用户数据，制作升级包时添加–wipe_user_data参数。
制作清除用户数据的差分包
./out/soong/host/linux-x86/bin/ota_from_target_files --wipe_user_data -v --block -p out/host/linux-x86/ -i v1.zip v2.zip update.zip
制作清除用户数据的全包
1.先使用make otapackage编译出素材包，文件是\out\target\product\k61v1_32_bsp_2g_ago\obj\PACKAGING\target_files_intermediates\full_k61v1_32_bsp_2g_ago-target_files-mp1V15202.zip
这个也是用来制作差分包的文件
2.使用命令生成可清除用户数据的全包
./out/soong/host/linux-x86/bin/ota_from_target_files --wipe_user_data out/target/product/k61v1_32_bsp_2g_ago/obj/PACKAGING/target_files_intermediates/full_k61v1_32_bsp_2g_ago-target_files-mp1V15202.zip full.zip
如果编译失败报如下错误，修改ota_from_target_files.py脚本
xxxx@xxxx:~/work1/xxx/xxx$ ./out/soong/host/linux-x86/bin/ota_from_target_files --wipe_user_data out/target/product/k61v1_32_bsp_2g_ago/obj/PACKAGING/target_files_intermediates/full_k61v1_32_bsp_2g_ago-target_files-mp1V15202.zip full.zip

ValueError: Cannot generate downgradable full OTAs
3.修改ota_from_target_files.py脚本
- build/tools/releasetools/ota_from_target_files.py
if OPTIONS.wipe_user_data:
if not OPTIONS.vabc_downgrade:
logger.info("Detected downgrade/datawipe OTA."
"When wiping userdata, VABC OTA makes the user "
"wait in recovery mode for merge to finish. Disable VABC by "
"default. If you really want to do VABC downgrade, pass "
"--vabc_downgrade")
OPTIONS.disable_vabc = True
# We should only allow downgrading incrementals (as opposed to full).
# Otherwise the device may go back from arbitrary build with this full
# OTA package.
- if OPTIONS.incremental_source is None:
- raise ValueError("Cannot generate downgradable full OTAs")
+ # if OPTIONS.incremental_source is None:
+ # raise ValueError("Cannot generate downgradable full OTAs")
最好使用vim去修改
