Howto make a permanent change to $PATH? - Droid Incredible Q&A, Help & Troubleshooting

Is there a way to make a permanent change to the $PATH variable to place /system/xbin ahead of /system/bin? I found /init.rc when the phone is booted, but obviously I can't make changes to that yet. When booted into recovery, I can't find the same file to edit it. The /init.rc file is specific to the recovery image at that point.
Basically, I have busybox installed in /system/xbin and want it to override the /system/bin apps. I do not want to install busybox in /system/bin.
Any help would be appreciated. Thanks!

are you trying to export a path? if so it would go something like
export PATH=$PATH /system/bin
or you can
PATH=$PATH /system/bin
export PATH

He's trying to make it so he doesn't have to reset the $PATH variable every time. I'm assuming you are currently just using something like.
export PATH=/system/xbin:/sbin:/system/sbin:/system/bin
every time you enter shell. The way I would do it is by editing the init.rc as you stated, however it doesn't stick on the incredible, also as you stated.
The only thing I can recommend is making it a shorter PATH to type. You could just enter
export PATH=/system/xbin:$PATH
for example, and that would accomplish the same thing with less typing.
The only other way that I know of would be to make a start-up script, not sure how to accomplish this outside of init.rc however. In linux I would add it to the bash_profile or something similar. Not sure how to do it in android...

Not only for shell, but I'd like to be able to do it for installed apps as well, such as OpenVPN. Ah well, just have to wait for full root unlock.

This is done in the ramdisk. You can actually do this yourself. You need to extract the boot image, break it apart into the ramdisk and kernel, alter the init.rc file, package it back up and then flash it back to your phone in recovery.
Even if we get the nand unlocked, you will still need to do this since the init.rc recreates itself from the ramdisk during each boot.
If you are using a custom ROM, just request the dev to do this.

Thank you kindly, didn't know where those files were kept. Interesting how that works, so basically the phone works like a hardware chip, where the main parts of the OS recreate themselves from ROM, similar to firmware... I like it... prevents corruption I suppose.
Out of curiosity (I've never made a ROM, and therefor never packaged the boot image), is it packaged as a tarball? Or do you require ADB to extract? If you don't want to answer, I can probably track it down somewhere.

It's a bit more complicated than that. Take a look at this link. I'm sure there are other ways, but I would recommend only doing this in some flavor of Linux like Ubuntu.

Cool link. Thanks.
But yea, pretty much seems to be that simple, Just a gzip (zip) and tarball (cpio). The only thing I wasn't expecting was stripping out the 2k header with a hex editor, but I think I'll try using the scripts found through that link to do that, not that I couldn't do it by hand... but I'm lazy...
Thanks again.

Dev Question.

If I want to customize a ROM that I have in update.zip format, do I just manually modify the contects of the update.zip and change the update-script and build.prop files or should I be doing this another way through an IDE or something?
If so, can someone please link me to where I might get some relevent info?
Thanks.
dsixda's kitchen will let you pretty much cook and modify any ROM.
I wouldn't use the root function on there, but if you look at the No Idea Blog link on the first page of that thread it tells you how to add root permissions if your ROM doesn't already have them (it's really easy).
Also, if you're on Windows and don't like the fact that you can't use the kitchen to its full potential, you can download a copy of Ubuntu Linux and VirtualBox (both free) and run Ubuntu as a virtual machine within Windows. Alternatively you can try WUBI as pointed out by kendong2 here
Using the kitchen will ensure that your customised ROM is signed - Amon RA requires signed update.zips, I think there was something called Clockwork Recovery which doesn't need the package to be signed.

Thanks, I'v already managed to add root myself a few times to various ROMs so i don't think that'll be an issue.
Does the ROM need to be re-signed on each modification? Which is why I wouldnt be able to edit it manually?
Thanks again.
EDIT: I have no problem running linux, infact I have Ubuntu on my laptop and will install Fedora 12 on my desktop now.

yes resign after every update. just unpack, modify, repack and resign. not that complicated if you get yourself some handy scripts (write them or use dsixdas kitchen).

As far as I know yeah (unless you're using that other recovery image I mentioned). It's pretty easy with the kitchen - press 9 and it cooks the ROM. Takes about 2-3 minutes for each bake - its flashing the ROM that takes ages.
You could sign manually, I'm sure I found a tutorial on how to do that when I was modifying some apps.
It works fine on OSX too. If you read the first post, he does say some things won't work on Windows. Like I said, you could use VirtualBox or WUBU which will save you the hassle of extra hardrives, partitions, dual-booting and all that.
Q
Ok, got the kitchen open under linux now, first question is this, the ROM i'm using doesn't have a system.img, it has a folder "system" so it naturally won't let me continue in the kitchen without it, how do I solve this problem?
Thanks.
To customise an existing ROM, extracts all its contents.
In the kitchen make a folder starting with "WORKING_" the underscore can be followed by any name of your choice e.g. WORKING_ALIASNEOROM
Inside that folder paste the boot.img, system, META-INF and data (if its there) folders from the ROM you extracted.
Inside the META-INF folder delete the 3 files - just leave the com folder.
After that you should be good to go with the ROM.

Thanks a lot, really appreciate the help.
One more question, hopefully the final one, when i remove apps or add them to the relevent folder, are permissions and linking taken care of automatically where necessary?

No problem, I was in your shoes a couple of weeks ago! Yeah, you just copy the apks - worked for me so far.
Most ROMs come with a data/app folder, but incase yours doesn't just create it next to the system, boot.img etc and then in the update-script add:
Code:
delete DATA:app
copy_dir PACKAGE:data DATA:
set_perm 1000 1000 0771 DATA:app
before the format CACHE command.

Where can I find the syntax for this file? I like to understand the commands so I can use them properly, i get that set_perm is setting permissions and 0771 are the permissions being set, but what are the "1000 1000"?
Google wasn't my friend this time and I couldn't find a syntax.
Have a look in here, I've not got enough Linux experience to tell you how those permissions work. I update that file by comparing ones from other ROMs and slowly got the hang of it.
Cool

Exactly what I was looking for, thanks.
Just failed two flashes because of:
1) because i conned the kitchen into setting up the working folder (by putting a fake system.img) it didn't delete the symlinks so i had to do it manualy (after trying to flash then figuring out why it failed) and
2) it couldnt chmod "su" because it didn't exist, strange since i was working based on an existing ROM and didn't delete the "su" binary.
Question: How and where do I change the build name that shows up on the device to my own name?
EDIT: 3rd flash was successful but on boot it hangs at the HERO screen, logcat just says "waiting for device". Ideas?

Someone's custom ROM may have it someplace else. My kitchen was mainly designed for new cooks making their own ROMs from the stock ROMs.

I think it's in the build.prop. Just compare the field values with what you see on your phone right now for the build name.

That's what I don't get, the update-script isn't edited by the kitchen right? But the chmod command in the update-script was from the same ROM, so surely it's "su" binary should be in the same place the update-script looks for it, or am i missing something?

Thanks, I'v given it a go, will see what happens if/when i get a successful flash.
As for your adding that info from Ash to your kitch, I think it would be useful because I forgot the last line (setting permissions) and it just caused my ROM to hang on boot, reflashing now and hoping adding it was the fix. Will update this post once complete.
UPDATE: Still hangs on boot even with that line added. Where do I go from here in debugging since I can't get logcat?

If you used my instructions about the WORKING folder earlier, then you don't need to use option #1 in the kitchen to setup working folder - that's only if you're working with stock images. The result of that command is a WORKING folder - which you already have by extracting the files and making that folder manually.

You only need the permission twice if its for the recursive set, because the first is the directory and the second is it's contents.... or so I believe.

[Q] SU not working

I am just about to release my new barebones build with a lot of new features but one thing is killing me. I cannot get superuser to work anymore with the latest build and the latest kernel. Rogue tools won't overclock without SU working and that just totall kills the speed of my build =(. The build is based off scoot's release 5 and I am using the latest kernel with and without the module update SU is unaffected. Everything else works though.
What have you changed from the build i sent you that might effect it? Does it work for you with the original build? Things to check are the sysinit.rc, make sure it calls userinit.sh on startup, and also check your userinit.sh in the /bin directory and make sure the su fix is still present in the file Otherwise, try opening the super user app and downloading the latest su binary file, if it fails to install then you most likely have partition permission issues.
I did edit userinit to enable the odex script. I am gonna check that now.
Ok I am pretty sure that was it. how do I add this line to userinit to have it be proper then? /system/bin/odex.sh

You'd need to put it in sysinit.rc like this :
service odex /system/bin/odex.sh
So put that line right at the end then? Or is there a special format it has to go in. Sorry, I have just never had to edit this particular file before lol.

At the end is fine, you will see some similar lines in there, you may want to add some options such as :
console
user root
oneshot
I don't know what the structure of the odex script is so i don't know which options you will need to get it to run properly but these are the most likely, just experiment and see
I've always put it at the end, after the su fix just as "/system/bin/odex.sh" and nothing else. What does service do? will it run it continuously or just with different permissions?
I would say its more likely that something's gone wrong while you edited userinit.sh, and now it can't be executed.
did you edit it in windows? you may have /n/r line endings now instead of /n
if you did it in linux it may be a permissions problem
fixed! I used the userinit from my old barebones. Something changed in the update. The two looked totally different.

Finally the tutorial
Make your own Android Build for the HD2 by domineus ​I have always lived by these words- if you give a man a fish, he can eat for a day; but if you teach a man to fish you can eat for a lifetime. Android on the HD2 has always been an interesting thing for me and I know a lot of people that want to create their own builds, but have no idea how. If you ask a build creator or maybe someone in the htc-linux-chat how to get started, there may not be an answer. In fact, some of the perplexing behavior has left me puzzled in several ways - as if how to get an android build is a vaulted secret of knowledge like the holy grail. To be honest, it's not. It's a bit of hard work, a few nods in the right direction, and ultimately it's a community involved project. Just like miui development is a community project spanning actual continents to get this thing on our device every single week! It has led to a lot of questions, in my inbox, of how to begin. For a long time, the answer to the question was not answered until Cass helped me out. I want to do the same and contribute how to get a build of miui (or any android build) to the HTC HD2.
Things you will need
In order to properly start android development, it would be a good idea to make sure you have the following (a lot of it is no duh when you think about it)
A computer running linux
I can't stress that enough. While there is a lot of things you can do in windows, you will need some sort of linux distro in order to get android properly running on your HD2. There are a lot of linux distros you can use; with many using ubuntu as it is the most user friendly. I use Fedora and I am quite happy with the results. It's simple and effective. It gets the job done. Get a distro that you feel can get the job done.
Android SDK - either windows or linux
Android SDK is something that can be freely accessed and downloaded from the following location:
http://developer.android.com/sdk/index.html
It is a developer environment, but probably the most important thing you can use here (for the time being) is logcat. Logcat provides you to visually see the libraries and files working together to get android to work as well as if you run into an issue, it is the first thing you should resort to. For instance, boot reloop? Take a look at your logcat and try again.
A kernel
There are quite a few kernels available for android previously and they are divided into evo kernel or nexus one kernel. Many builders have transitioned to an evo kernel for PPP and a few other nice details but it is totally up to you. I highly recommend hastarin's kernel. For most of the time, it works well. But as you have noted, on MIUI, it hasn't been working as fantastic on other builds.
Donor Files
This is a bit difficult to find because it appears that the files that work best are nexus one builds without CM6.1 modification. So far, only one chef has that and it is tytung's nexus one build. Regardless of whose files you're using (e.g. tytung or darkstone's system which is the preferred choice) you will need a well working android build. You will be pulling several files in order to port.
MIUI itself (well any build honestly just miui is a good example)
This is a given. However, if you download from miui.com you will probably have an untranslated rom with odex files. That's bad. And in Chinese! It would be a good idea to browse the English forum for a deodexed rom with appropriate english translation (apps and frameworks)
-If pulling files from windows, you will need this
system extractor
http://uranus.chrysocome.net/linux/explore2fs-old.htm
I use that if I download in windows. It's relatively straight forward and it allows you to pull the files you need from the system.ext2 you're using and copying them to folders necessary.
build.prop
This you will need. You can find one here:
http://www.multiupload.com/B59IU3S6XY
Patience
Probably the most important thing. One thing I have noticed is you need patience to make it through. Sometimes, your build works, sometimes it doesn't. And it is difficult to still keep going. But gotta pull it all in and keep trying...it does pay off.
Okay so you have your files, a nice linux distribution, your build you want to port (MIUI preferrably) and you're ready to go. Now it's time to begin the process!
Step One - The Setup
I usually grab my files in windows before transitioning to my linux distro to finish the process. If you using windows 7 and you are using explore2fs, you will definitely have to right click on the exe and make it compatible by selecting compatible with windows vista. The file should also need to be run by administrator. If you don't know how to do that you can google compatibility in windows 7.
First thing is first. Create a new folder, you can call it donor_files if you want because name is arbitrary. The most important thing is to just name it. Within that folder, create a new folder called system. Enter the system directory and create a new folder called etc. Within etc, select Once that is done, create a new folder within etc called firmware. Once completed, return back to the system folder, create the folder called lib. In the lib folder, create a new folder called hw. So your folder should look like this:
Folder Name
-system
--etc
---firmware
--lib
---hw
So far so good? Excellent. Now, if you're in windows you will need to do a few things. Extract the system.ext2 of your donor build and place it somewhere you will remember (like your desktop). Now open up explore2fs, select file, and open image file. Under files of type (drop down), select all files and navigate to your system.ext2 file. You should now see the ext loaded on the left side of the program's workspace. Located is a very small + that allows you to view all directories in your ext2 file. Click that.
You will see several system folders on the left and files on the root. Since you haven't selected a specific folder, in the right hand view, you should see the file build.prop. If you did select a folder (like app) you will see some files. And that's okay too. Get a feel of the program.
Now you will do a test file pull. On the left hand side, select the folder etc. On the right window, you will see several files. We want AudioBTID.csv. Once you see the file, right click on AudioBTID.csv and select export file. Navigate to the donor file folder (or whatever you named it) and place the file in system/etc of that folder. Congratulations you just pulled your first file! But you will need a lot more files. Within the same directory, pull gps.conf, hosts, media_profiles.xml and the ppp folder. Now, navigate to firmware and pull the following files:
BCM4329B1_002.002.023.0360.0362.hcd default_france.acdb htcleo.acdb
BCM4329B1_002.002.023.0436.0439.hcd default_nel.acdb yamato_pfp.fw
bcm4329.hcd fw_bcm4329_apsta.bin yamato_pm4.fw
default.acdb fw_bcm4329.bin
Ideally you should not be able to find htcleo.acdb. You can find it here
http://gitorious.org/xdandroid_leo/q...eo/htcleo.acdb
Now in explore2fs, go to the lib directory and pull these files and place them in your lib directory:
libcamera.so
libcamera_client.so
libcameraservice.so
libhtc_ril_wrapper.so
libmm-omxcore.so
liboemcamera.so
libomx_aacdec_sharedlibrary.so
libomx_amrdec_sharedlibrary.so
libomx_amrenc_sharedlibrary.so
libomx_avcdec_sharedlibrary.so
libomx_m4vdec_sharedlibrary.so
libomx_mp3dec_sharedlibrary.so
libomx_sharedlibrary.so
libomx_wmadec_sharedlibrary.so
libomx_wmvdec_sharedlibrary.so
libOmxCore.so
libOmxVdec.so
libOmxVidEnc.so
libqcomm_omx.so
libstagefright_omx.so
Once those files are pulled, navigate to the hw folder of the system and pull the following files:
sensors.htcleo.so
lights.htcleo.so
Once those files are pulled, you can save your donor files to a flash drive and then boot into your linux distro. Login to superuser in terminal. For fedora, the proper method involves typing in su --login and entering your password you set up. Minimize your terminal window.
Extract the miui (or any other build) to your desktop (the focus is the system folder). Ensure the rom is deodexed and in your own language (if its miui, you will have to apply the proper language translations). Now copy the files you pulled from your donor build and apply it to the appropriate folders (usually a copy and a paste-literally). In this instance there will be duplicate files, overwrite them. That's the point! Do not forget the build.prop file I linked to earlier. You should add that to system folder.
So the files are copied, the next step is to restore the minimized terminal window (the one that is logged in as root). cd to where your system is located (not to the system folder itself). Now you will have to enter the following commands in terminal
chmod -R 777 system/etc
chmod 755 system/bin/*
chmod 755 system/xbin/*
rm system/etc/firmware/default*acdb (if you have sound in call issues)
touch system/etc/ppp/active (If you have latest wrapper and need ppp)
chown root:2000 system/bin/pppd
chmod 4755 system/bin/pppd
chown root:root system/xbin/su
chmod 4755 system/xbin/su
chown root:root system/xbin/hci*
chmod 4755 system/xbin/hci*
dd if=/dev/zero of=system.ext2 bs=1048576 count=256
mke2fs -F system.ext2
sudo mount -o loop system.ext2 /mnt2
cp -rp system/* /mnt2
sudo umount /mnt2
A few words on this that I must bold. the /mnt2 directory may not exist. If not, try mnt, that usually works
Once this is done, you will have a nice system.ext2. The only thing you'd need now is a rootfs, a kernel, clrcad.exe and a startup.txt file. Once that is done, you can test your build out.
Any questions
Special thanks to Cass and the htc-linux-chat for the few pointers they gave me.
The guide is by "domineus - http://www.miui-dev.com/" & I take no credit what so ever​
Thanks to "white-energy" for giving us the link..!!!
Hope to have many more Chief's for our HD2, so that we [especially me] can satisfy our hunger to try different builds/ROM's..!!!
Happy Cooking..!!!​
PLEASE PRESS THANKS IF YOU FOUND THIS THREAD USEFUL..!!!​​

Can anybody out there give us a step by step guide for cooking a NAND ROM for HD2..???

Instead of making a ext image, you should make a yaffs image.. so it can work on Nand

I've been looking for something like this. I want to create my own build for the recovery flasher. I guess the only thing needed would be how to convert from regular nand to recovery.
Thanks bro.

Are you sure its the only difference? Are the nand drivers stored only in the bootimg/initrd and not somewhere in the system.img?
yes or no will do for me thx
Is there a way to edit system.bin files, that comes with the NAND builds. I suppose that is where the ROM is. I want to unpack, edit the included apps and repack. How it is done? How the bin file is done. Google does not give any satisfiable links, did a quick search, though...
i am confused
Which explore 2fs do I download? There are 3 different ones one for binary one for code and optional update source code. I am a noob and tired of not having roms I am happy with. I have windows 7 and xp. I realize this will take time and I am good with it everything thats worth anything takes time.

I think you mean system.img not system.bin
You can extract them with the unyaffs.exe or with the unyaffs command under linux. I have written a guide with attatched utilities here
Additionally birksoffsjunk (seasoned WM guru & chef of ChuckyDroid, ChuckyROM, & Dexter) has made a batch program to make this process easier. It's a work in progress & somethings are still buggy so follow the thread
Between the utility birkoffsjunk made & the tutorial I wrote you should be able to successfully edit & run your own build. Hope this helps.

It's an archive that can be decompressed and edited thru linux.
White-Energy use system.bin in his rom
Regarding initr and zimage, there is a guide that you can point me on ?

I have only green HTC
Hello
I would like to use Android on my HD2. I was searching and testing many ROMS but I didn´t find any rom which is usable for me. I would like to have a ROM that is without Sense, has Multilanguage support and is on Android 2.2 version.
So I decided that I would make my own.
0) I was reading
HTML:
http://forum.xda-developers.com/showpost.php?p=10291851&postcount=1
and made this procedure.
1)downloaded some ROM from here
2)unpacked this rom in linux with :
Code:
unyaffs system.img
then I got this directories:
Code:
app bin build.prop etc fonts framework lib media usr xbin
3)I downloaded update-cm-6.1.1-N1-signed.zip from CyanogenMod Forum > Downloads > Stable Mod > Nexus One and unpacked. I got : META-INF system boot.img.
4)I copied everything what was described step 0 from directories from step 2 to directory system from step 3
5)I downloaded and copied build.prop from step 0 to system
6) I updated permition like it is described in step 0
7) I created system.img with command : mkyaffs2image . ../system.img
Then I copied this system.img from linux to my windows and put this file in directory in which was different NAND rom. (replaced system.img). After that I flashed my phone and it did not work. Screen was frozen after booting and only green HTC was on display.
Can somebody please help me and give me some advice or some small howto. Does anybody know what can be wrong?
Thank you
Michal Fichtner
I appreciate the guide but damn that is hard to read. It really needs some sort of structure to it, titling proper paragraphs etc.
Hi,
it is possible to combi the dropdown energy widget froom miui and the gingerbread lockscreen into Desire HD Build?

Edit build.prop through updater-script

Hello fellas.
Back in the day, if I wanted to keep my dpi setting of 280 after flashing a new nightly (talking CM now), I just made a local.prop with the modified line and put it in /data.
Since, I think, CM10, though, local.prop doesn't get loaded, so I have to manually change build.prop.
I know a solution to this would be just keeping the same build.prop and flashing it after the rom (I already have a zip with the modifications I like that I flash after each nightly), but I don't really want to keep an old build.prop. What I want is to juat modify the line through my zip, so it stays updated while I don't have to modify the line every single day.
I found very quickly that I can use this line:
sed -i 's/ro.sf.lcd_density=320/ro.sf.lcd_density=280/g' /system/build.prop
to get the job done, and it does indeed work if I run it using the terminal. The problem is, I can't get it to work in recovery.
Having very little experience with programming, I'm just trying stuff to see if it works. I treid directly including the like line in the updater-script, didn't have too much hope for that.
I also tried including another simple file with this code:
#!/sbin/sh
sed -i 's/ro.sf.lcd_density=320/ro.sf.lcd_density=280/g' /system/build.prop
that I then extract and run, as I've seen in threads in the forum, but still doesn't work. The file gets extracted, but it doesn't work
I even tried to do it in a userinit script form, just to see if the rom loaded it on boot, but nope.
This is pretty friggin' simple to do, and I'm sure I'm probably making a silly noob mistake, but I just don't have any experience with this kind of code, so if someone can tell me how to make my zip run that very simple line, I'd much appreciate it.
Thanks.
Ok, after moar and moar and moar search, I finally found a script that does the job.
Problem solved.
yay
yay
Hi,
can you please provide your solution. I'm also trying to edit values in build.prop.
I tried to do via init.d script. The script is fine but / system seems to be read only when executing script at startup.
So it would be great if you can reply how you did it (maybe complete other way).
Thanks in advanced!
This is the post in question.
Swiftkey'd from my GNexus
Perfect, thanks a lot! I already found a workaround via an init.d script but this looks very promissing....
Sent from my XT894 using xda app-developers app
It's very useful.
I just included it in my after-nightly zip, so everything becomes automated with cyandelta.

Hi,
So how do I edit AND add lines to build.prop from recovery ZIP?
Easy solution
Or maybe using just the updater-script and this code (this should also work on every rom)
run_program("/sbin/sh", "-c", "sed -i 's:ro.sf.lcd_density=.*:ro.sf.lcd_density=280:' /system/build.prop");

You can change 280 to another value if you want.

Sir can you tell me what to do to change ro.product.name if same phone in different regions is having different ro.product.name so that the build.prop for every phone that's installed.

any solution to fix the fingerprint on GSI?

Does anyone know if they already have a solution to fix the fingerprint on any GSI on the moto g7 play?
I don't think there will be a fix for it. GSIs are basically developed for testing purposes and are not functionally ROMs.

I'm working on this right now. It requires a jar from /system/framework, and some libs from the stock OS. And maybe an overlay, but that part I'm unsure about. If I get anything working I'll post a flashable zip.

man, you are the g7 play hero ngl, can you post an explanation of what needed to be done when youve done it, you know like the technical side, so people like me can learn?

I use a few methods in general to figure stuff out.
1. Google, Arch linux Wiki, stack exchange.
2. Sleuthing. Go digging though system files or app manifests.
3. Poke it with a stick. Running strings or grep on a file for keywords. Poke the box with the right input, and it'll often give you prizes in return. This is especially true for things you can't just decompile like a bootloader image. You can even do things like tease partition mounts from a vendor image this way.
4. Load files into a hex editor. I personally use HxD. This works similar to the poke the box method. If strings and grep are like a radio, then using a hex editor is like watching TV.
5. Don't reinvent the wheel if you don't have to. Look for things that you know accomplish the same, or a similar task, then adapt them to your situation. This isn't always easy but 90% of the time it'll get you there or damn close.
This project is a combo of 2 and 5.
I first went digging through system and vendor files. I know from prior experience that apps and hardware features often require library files (/system/lib/*.so), bin files (/system/bin & /vendor/bin), jar files (/system/framework/*.jar), and permissions (/system/etc/permissons & (/vendor/etc/permissions). Occasionally hardware features also have an init script to start them. (/system/etc/init & /vendor/etc/init)
So I searched with a root explorer for any files in those locations that have "finger" in the name. That gave me gold. I made a note and created a file structure to match them, then copied the files over and created a zip.
This is where #5 comes in. In order to flash it, we need a script to tell twrp how to mount the partitions we're going to modify, where the files go, and what file permissions to set. (rw-r--r--, 0755 etc.) I knew how to do this from modifying phh's su to work on Lineage OS 17. And I learned how to do that by looking at the flashable zips for, viper for android, and the universal disabler. Since I had adapted those for Phh su, when I needed to do it again, I pulled the scripts from Phh su and edited them to use the new files and permissions.
That's the jist of it. If you want to see how the scripts are written, extract the zip and look at META-INF/com/google/android/updater-script with a text editor. I recommend either Quick Edit pro for android, or notepad++ if using Windows.
Finger Print Test #1
If anyone running a GSI wants to test this, just flash it in twrp and let me know if the finger print sensor works. It should NOT break anything. If you get any flashing errors please tell me. It means there's a typo somewhere in the scripts and I need to fix it.
