Can't install on 4.4.4 tablet due to missing $RANDOM generation method.

[KhazAkar]

What happened?

Hi!
I'm running Alcatel Pop 8s with CM11 (KitKat 4.4.4). I know, it's ancient, but I wanted to revive it and have microG running. I'm unable to install it via sideload, because of such error:

ERROR 79: $RANDOM is not supported

Version

1.3.1-beta

Android version

4.4.4

Custom ROM

CyanogenMod 11

Relevant log output

No response

Hi,
I didn't expect anyone to have this error, but it should be easy to fix.

Could you please try this and report back?

Same error code, but got different log - "ERROR 79: Unable to generate a random number"

[KhazAkar]

What's more interesting is that I can see in /dev after doing adb shell in recovery /dev/urandom and /dev/zero ... interesitng.

@KhazAkar
What are missing are the other things.

Could you please run these in adb shell and tell me the result of every line?

command -v shuf; echo $?
command -v awk; echo $?
command -v date; echo $?
date -u -- '+%N'
command -v tr; echo $?
command -v head; echo $?
command -v dd; echo $?
command -v hexdump; echo $?
command -v od; echo $?
od --help

@ale5000-git sorry for screenshot, but I hope is everything visible :)

@KhazAkar
Could you please retry with this and report back?

Went further, but now got a different error. Should I create a different bug ticket, or we will continue here? Log retyped from display below:

@KhazAkar
We can continue here in this ticket but I need the full log.

Could you please try this version (the log is enabled by default)?

You will see a line like this (path may be different):
Creating log: /sdcard1/debug-a5k.log

Then after the flashing is ended you just need to get the file with:
adb pull "/sdcard1/debug-a5k.log" debug-a5k.log

And post it here.

I've pulled debug-a5k.log as well, as recovery.log. debug-a5k.log doesn't contain that much more than I gave above. This tablet seems to use /tmp for sideload.
recovery.log
debug-a5k.log

@KhazAkar

Could you please post the result of this?
adb shell "ls -laR /system"

Since it may be big it may be better to save to file with:
adb shell "ls -laR /system" > file_on_the_pc.txt

It seems that now it works fine. Skill issue on my side, sorry! :D
After mounting manually system it installed now. Maybe auto-mounting /system when it's not mounted would be a good idea, or having it in docs?
BTW, where can I give you some $$ for your work? I wanted to appreciate it somehow your dedication to help me :)

[ale5000-git]

It already has auto-mounting of /system but currently it does have an issue in your specific case but I will fix it soon.

Thanks for your reports too; I like programming and I want to fix all issues, no matter what it is.

Only thing left is that I get "com.android.acore" crashing on start, plus logging is quirky, and GPlay, but that I can handle in different ticket. At least it works now :)

[ale5000-git]

The issue with automounting was that the "System mountpoint list" was empty.
Usually there are 2 cases:

1. Under the "/" mountpoint there is an empty system folder that is used as mountpoint for the real system partition;
2. Under the "/" mountpoint there is a system folder with inside a bin folder; if it is used as mountpoint then binaries under /system/bin (from the "/" mountpoint) are no longer usable. So in this cases my installer avoid using /system to mount the partition.
   In this second case usually there is a /mnt/system mointpoint that can be used but in your case it is missing.

Now I have changed the code to use a fallback mountpoint if there isn't anyone usable and it should fix automounting on your device.
Could you please try it and report back?

About the other issues

• "com.android.acore" crashing on start => please open a separate issue for this.
• logging is quirky => What do you mean? The log currently can't activate too early but usually there isn't any problem this early (the issue with random is really a rare case).
• GPlay => What is the problem?

[KhazAkar]

1. Sure, will check it out whether possible.
2. Sure, will open separate ticket for that when it will rise again
3. Logging in is quirky - sorry for misspelling. It wasn't ending the procedure of logging in to the account, but after skipping I was logged in.
4. Before reboot it was unable to open the application.

Hello!
i'm sorry it took so long.
I've tested that zip and it appears to be working. Currently it detects my device as 32 bit only. Qualcomm Snapdragon 410 AFAIK is 64 bit cpu. Is it because underlying android is probably 32 bit or something else?

EDIT: as of acore thing - it's android.process.acore specifically. During initial screen. Will create ticket for that.
