factory_reset.sh does nothing except echos "NG"

[frankli998]

Below is the code of factory_reset.sh, which does nothing except echos "NG" when runned.
I am aware of a similar issue #95
,but the user do not seem to have solved the issue eventually. PS: Suggested launcher-mod is highly likely to cause this issue.
My device is hacked using windows10. Tried re-flash 1.6 firmware or downgrade to 1.4, neither worked for me.

root@FPX-1010:/usr/local/bin# cat factory_reset.sh
#!/bin/sh

. diag_functions

default_destructor ()
{
echo NG
}
trap default_destructor 0 2 11 15

shutdown_screen=/usr/local/etc/factory_reset_$(rawdata --sku_name).bmp
if ! test -f $shutdown_screen; then
exit
fi

opt=$(getopt -o e --long no_epd_init -- "$@")
if test $? -ne 0; then
exit
fi
eval set -- "$opt"

epd_init="gray INIT FULL 0"

while true; do
case "$1" in

unset epd_init

you can try to run it manually and see which part didn't work out and exited

I don't think launcher-mod could cause such issue but you can prove me wrong

you need to bypass the official version check, i.e. use my modded firmware to downgrade. Otherwise it won't flash at all. And after flashing, very likely you need to reset by going into "Settings" > "Initialize DPT"

"I don't think launcher-mod could cause such issue but you can prove me wrong"
Yes, I guess you are right. I reversed launcher-mod and re-flashed but the problem still exists.

"you need to bypass the official version check, i.e. use my modded firmware to downgrade."
I did use your firmware, and it actually downgraded successfully, since the version number changed in settings when I checked.

"You need to reset by going into "Settings" > "Initialize DPT".
I have tried both "going into "Settings" > "Initialize DPT" and run factory_reset.sh under diagnosis mode, neither worked. So what do you mean by running it manually?

[frankli998]

Another question, is there anything different between "fw" in normal mode and "install-pkg" in diagnosis mode?

[frankli998]

OK, reason found. In 1.6 full-mod, there is an native application named TestMode, I changed my SKU from Japanese to Chinese, and this seems to disturb factory_reset function. Changing the SKU back to Japanese edition solves the problem.

how to change sku? thx @frankli998

[frankli998]

1. Root dpt-rp1 2. Flash 1.6 full mod, this pkg can be found in "PKGs I made" wiki section in this repository 3. Open eink-launcher, launch Testmode, a native apk, and you will see the option to change SKU ---原始邮件--- 发件人:"chaoskin10"<notifications@github.com> 发送时间:2019年7月15日 星期一 上午8:59 收件人:"HappyZ/dpt-tools"<dpt-tools@noreply.github.com> 抄送:"frankli998"<605212980@qq.com>;"State change"<state_change@noreply.github.com> 主题:Re: [HappyZ/dpt-tools] factory_reset.sh does nothing except echos"NG" (#116) how to change sku? thx &mdash; You are receiving this because you modified the open/close state.
