[Tweak] Boost RAM Management - get more free RAM! // [23.03.2011] Fixed Permissions.

Memory Tweak - get more free RAM to use for apps and less lag.
// This was first intended for other ROM chefs, so they can include this tweak in their ROMs. I'm aware that there are apps which can do this. But it's the idea to have it included automatically, so you don't have to annoy your users
However, this is also for normal users. Those just flash the CWM Package thunderteaser made here. Thanks for this.
I made a script which boosts the RAM Management significantly.
You can use this in any ROM - those values have been created from my mind and were being tested for several days in heavy use.
IMHO, it's the perfect combination of RAM Management.
HOW TO IMPLEMENT IT INTO YOUR ROM
Just make a new bash script and place the following code into it.
NOTE: bash files created on Windows don't work. Create them with a UNIX like Linux (Ubuntu, Fedora, whatever) or Mac OS X.
Place the script in /system/etc/init.d so it gets automatically executed at every startup. You have to make this because init.rc (in root dir /) gets executed first and will also set the RAM Management (minfree) on his own.
UPDATE - 20.03.2011
Supercurio said, there is support for init.d in his Voodoo injected kernel for JV1 Gingerbread.
This means, the script is fully working and the Gingerbread JV1 memory leaks are fixed when using those values.
This also means, my current ROM v10.0 Beta 3 already has the Memory Hack integrated.
Code:
#!/system/bin/sh
# DarkyROM 2011 - Joël Staub (darkyy)
# This will stabilize the memory leaks in Gingerbread and other ROMs.
# Adjusting Memory Settings
# The values in MB: 10, 16, 24, 68, 76, 92
if [ -e /sys/module/lowmemorykiller/parameters/minfree ]; then
echo "Modifying minfree parameters"
echo "2560,4096,6144,17408,19456,23552" > /sys/module/lowmemorykiller/parameters/minfree
else
echo "minfree not found"
fi
Permissions
You may want to adjust the permissions of the script when it's on your phone.
You can do it with ADB.
First, connect to your phone.
Code:
adb shell
Get root access.
Code:
su
Set the permissions.
Code:
chmod 777 /system/etc/init.d/ramtweak
Code:
chown root:root /system/etc/init.d/ramtweak
When you're a ROM chef, you can include those permissions either with update(r)-script or with a bash file.
Thanks to zacharias.maladroit for the hint with the permissions.

Ok this looks awesome but for the most part of the members can u make a proper tutorial ? I really don't understand how to implement your hack, how to create a bash script init.d ?
sorry for my noobiness
And when you say in every ROM, did you also mean every custom kernel ?

You just make a new file on your COMPUTER.
Or it would even work on your SGS (but I'm writing now for the Computer).
Example:
Let's say, you're on Windows - create a NEW text file and remove the .txt extension (you need to have this option activated in the explorer settings).
You can leave it to no extension or just make it end on .sh
You got a file called randomname.sh now.
Now to make it easy, just copy this file to the C: drive in NO subfolder.
Now just ADB push this file to your SGS into:
Code:
adb push /randomname.sh /system/etc/init.d
Or just copy the .sh file to your SGS via USB Storage mount and copy it to the directory with Root Explorer or Super Manager.
Yes, this should work with every kernel (Android 2.2.1) here.

Thanks for doing this testing to find good settings. Forgive me if I'm misinformed, but is there anything particularly innovative about new minfree settings? I do appreciate your testing and finding ones that work well for you.

have a good rest, Darkyy !
thanks for this script
so you noticed improved interactivity with "apps and less lag" ?
gotta try this with CM7
FYI:
the defaults of the CM7 kernel are:
Code:
cat /sys/module/lowmemorykiller/parameters/minfree
2048,3072,4096,6144,7168,8192
edit2:
make sure that you get the right permissions for the file on the phone afterwards
say:
Code:
chmod 750 /system/etc/init.d/99rambooster
chown root:shell /system/etc/init.d/99rambooster

thanks for explanation ! I have done what you say and rebooted my phone after that. I renamed the file to init.d after placing it into the /system/etc/ directory and setted the défault permissions for this file rwxrwxrwx (or something like that)
But how I find if I have the hack succesfuly installed ?

Not innovative - this is nothing new.
It's just that many ROM devs aren't aware of this and I thought I could share my script.

EDIT:
Ouch, CM7 really has 2048,3072,4096,6144,7168,8192?
That's really not the best value... looks close like JV1 RAM Management at first glance...
I'm gonna check that later.

Thanks Darkyy! Once again, you kicketh ass!
I am gonna give this a try.

Nice, some info on min free settings:

while we're at it:
you could include lots of stuff from the
tweak script for the Galaxy Spica
in your next revision of ROM
I'm using some of those
and planning to continually add more after having tested them

Gah this is such a retarded suggestion. Darky your SGS ROM is really nice and I'm currently running it, but please think about things like this before you post them.
The SGS has, comparatively, RAM out the wazoo. Why do we want more of it sitting idle and unused? RAM is there to be used, not sit there looking unused and pretty like a virgin at an eastern european slave auction in a free -m command. Twatting about with this setting on behalf of the Android Low Memory Killer is essentially like telling the ROM you have less RAM than you actually do since it will always endeavour to keep that much RAM -free- as in -unused- by the GUI itself as well as Android apps.

Darkyy, so I just copy the codes, paste in notepad then save as [anygivenname.sh] then paste into system/ect/init.d using root explorer and reboot my galaxy s?

Darky is this included in your rom? if not is it going to be?

guys
seriously: read what comes after the 1st ,2nd and 3rd post - or the first 1-3 (or 5 sites) if it's a larger topic
you'll see that you need to change the permissions & owner
you do that via logging in via adb, becoming root (su)
and navigating to /system/etc/init.d/
or do it explicitly from the folder where you are - like I posted
0) prepare file on windows / linux / mac
Code:
#!/system/bin/sh
# DarkyROM 2011 - Joël Staub (darkyy)
# This will stabilize the memory leaks in Gingerbread and other ROMs.
# Adjusting Memory Settings
# Old Hack (you can ignore this, it's just another method of doing it)
#if [ -e /sdcard/darky_tweak/init.rc ]; then
# echo "Copying init.rc to /"
# cp /sdcard/darky_tweak/init.rc /
# else
# echo "No init.rc found"
#fi
# New Method [15.03.2011]
if [ -e /sys/module/lowmemorykiller/parameters/minfree ]; then
echo "Modifying minfree parameters"
echo "2560,4096,6144,17408,19456,23552" > /sys/module/lowmemorykiller/parameters/minfree
else
echo "minfree not found"
fi
e.g. save as:
99rambooster
1) dl & install Android SDK
http://www.talkandroid.com/android-sdk-install-guide/
2) connect phone
navigate to tools folder (or from Linux: launch from terminal via command)
3) put it on the phone
Code:
adb push 99rambooster /sdcard/
4) log in to phone & become root
Code:
adb shell
(now in phone)
Code:
su
5) copy it to init.d folder [you eventually need to remount /system rw]
Code:
cp /sdcard/99rambooster /system/etc/init.d/
6) adjust permissions:
Code:
chmod 750 /system/etc/init.d/99rambooster
chown root:shell /system/etc/init.d/99rambooster

[MOD] XWJVH unlimited Browser Tabs

Hi all,
It is the stock XWJVH (Gingerbread) internet browser modified to open more than 4 windows.
You can visit up to 16 different web site at the same time but you'll probably miss memory before.
Note:
Once you reach the 8th windows, continue to press the "new button" and it will open an extra new window even thought that the counter will not display more than 8
For those who remain in froyo,see my thread for XWJS8:
[MOD] increased Stock XWJS8 browser limit
For JVK:
[MOD] XXJVK unlimited Browser Tabs
To install :
-copy the apk to your sdcard
-Delete the old Browser.apk in /system/app
-Place the new Browser.apk in there
Note:
Don't forget to be superuser and to mount the partition as read-write :
for stock kernel :
$su
#mount -o remount,rw /dev/block/system /system
#cp /sdcard/Browser.apk /system/app/Browser.apk
#exit
$exit
for CF-ROOT kernel, (thanks to ramad)
su
stop (phone will freeze, that's OK just move on)
busybox mount -o remount,rw /dev/block/system /system
cp /sdcard/Browser.apk /system/app/Browser.apk
exit
exit
adb reboot

Thanks for the link. I came across this thread by just manually going through the Galaxy S>Themes & Apps sub-forum. I tried searching "8 window" and "JVO" but that brought up loads of posts with these individual words in it...

Good to know. I may include this keywords when i post my work.

unzip archive cifs_md4_10.4.2.17.zip and extract cifs.ko & md4.ko
> adb shell
# mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
(...or if you have busybox already installed : # busybox mount -o remount,rw /system )
# exit
> adb push cifs.ko /system/lib/modules
> adb push md4.ko /system/lib/modules
> adb shell
# chown 0.0 /system/lib/modules/*
# chmod 0644 /system/lib/modules/*
# insmod /system/lib/modules/cifs.ko
# insmod /system/lib/modules/md4.ko
# exit
* available for any rom ( custom rom ) who already has busybox installed !

Thanks for compiling those modules, maybe not the best place to ask, but I'm just currious
if you had any issues with the 10.4.2.17 source code from ASUS, I wish I knew what I was doing wrong
but I had noticed the source was about 25% smaller than previous source I had downloaded from ASUS

During the Installation process in Aroma, i recognized that the percentage counter reamins at 0 and not as in for example Sonic4 moves to 100 %...
Hopefully that will help you to find and fix the problem.

Seems like your system wasn't mounted correctly! I would say goto mounts and storage and remount( unmount and then mount) the system partition! Then install again!
Be sure u r coming from an ics rom

No, i came from Sonic4, and i had already the same idea, so i tried to mount the /system manually before the installation where the log is from already. At the moment i´m installing again 4.0, but if i can also do another try with mounting the partition manually.

[LG V50] temp root exploit via CVE-2020-0041 including magisk setup

temp root exploit for LG V50 ThinQ with android 10 firmware
including temporal magisk setup from the exploit​
The exploit uses CVE-2020-0041 originally designed for Pixel 3 running kernel 4.9.
I have adapted the Pixel 3 specific exploit for kernel 4.14 that is used with LG phones running Android 10 with March security patch level.
This work has been done upon request of @Inerent who contributed not only with very fine donations, but also did all the testing on his LG phone, as I do not own any LG phone myself.
As an addon I have implemented setup of magisk v20.4 from temp root exploit included su permission asking notification support, that has been also a hell of work to get working.
SUPPORTED TARGETS
You can find currently running fw version with 'getprop ro.vendor.lge.factoryversion' command run in an adb shell.
LMV500NAT-00-V20m-LAO-COM-MAR-10-2020+0 - LG V50 ThinQ with V500N20m fw, 2020-03-01 security patch level
LMV500NAT-00-V20f-LAO-COM-JAN-31-2020+0 - LG V50 ThinQ with V500N20f fw, 2020-01-01 security patch level
LMV500NAT-00-V20b-LAO-COM-DEC-23-2019+0 - LG V50 ThinQ with V500N20b fw, 2019-12-01 security patch level
LMV500AT-00-V20g-LAO-COM-MAR-10-2020+0
LMV500AT-00-V20a-LAO-COM-JAN-24-2020+0
LMV500AT-00-V20e-LAO-COM-JAN-23-2020+0
LMV450AT-00-V20a-LAO-COM-JAN-15-2020-ARB00+2 - LG V50 ThinQ Sprint fw, 2020-01-01 security patch level
Please note, it is unlikely that any other fw version than those listed above would work.
The only (unlikely) case when the exploit could work with different fw version (or different phone model) would be that they would use binary identical kernel image in the firmware.
USAGE HOWTO
be sure to run supported firmware version on your phone (you may need to downgrade, involving factory reset)
enable developer mode options and in there adb debugging (eventually install adb drivers)
download the v50g8-mroot3.zip with the exploit attached in this post and unzip it
use 'adb push v50g8-mroot3 /data/local/tmp' and get temp root with following commands in 'adb shell':
Code:
cd /data/local/tmp
chmod 755 ./v50g8-mroot3
./v50g8-mroot3
If it worked, you should see something like this:
Code:
[+] Mapped 200000
[+] selinux_enforcing before exploit: 1
...
[+] Launching privileged shell
root_by_cve-2020-0041:/data/local/tmp # getenforce
Permissive
root_by_cve-2020-0041:/data/local/tmp # id
uid=0(root) gid=0(root) groups=0(root) context=kernel
root_by_cve-2020-0041:/data/local/tmp #
In case you get 'target is not supported', you may list supported targets with
Code:
./v50g8-mroot3 -T
and try to force one close to yours using '-t num' option.
Please see the 2nd post for magisk setup from temp root details.
Please be careful what you use the temp root for.
Changing something in partitions protected by dm-verity (or Android Verified Boot 2.0), like for example /system, /vendor or kernel boot partition, can result with a not anymore booting phone.
In such case you would need a way to emergency flash stock firmware to recover.
This is why it is called 'temp root' - you get a root shell only temporarily, it is lost with reboot and it does not allow to make permanent changes in crucial partitions until bootloader unlock is achieved.
Some partitions might still be possible to modify - for example in case of sony xperia phones it was possible to do permanent debloat via changes in /oem partition and such debloat would survive even factory reset. Similarly some modem configs have been present in /oem allowing to setup IMS for different operators/regions or tune other modem related stuff.

DOWNLOAD

MAGISK SETUP FROM TEMP ROOT WITH LOCKED BOOTLOADER
To enjoy the temporal root with apps asking for root permission, you can now start magisk v20.4 from the root shell provided by the exploit.
download the v50g8-mroot3.zip with the exploit attached in the first post
download Magisk-v20.4.zip from magisk releases page on github here
use 'adb push v50g8-mroot3.zip Magisk-v20.4.zip /data/local/tmp' to copy the zips to the phone
unzip and prepare magisk setup with following commands in 'adb shell'
Code:
cd /data/local/tmp
unzip v50g8-mroot3.zip
chmod 755 v50g8-mroot3 magisk-setup.sh magisk-start.sh
./magisk-setup.sh
get temp root and start magisk up with following commands in 'adb shell':
Code:
cd /data/local/tmp
./v50g8-mroot3
./magisk-start.sh -1
./magisk-start.sh -2
./magisk-start.sh -3
just this point should be done after each reboot to get magisk running again.
NOTE: please be sure to enter each command separately, line after line - do not paste all in a single block and do not put them in a script.
There are reasons this is divided in 3 stages. With this approach I got the best stability, while putting ./v50g8-mroot3 together with -1 and/or -2 stuff in a single script run resulted with a reboot most of the time.
Phases 2 and 3 need to be split for functional reasons to start magisk with working su permission asking notification.
If it worked, you should see something like this:
Code:
flashlmdd:/ $ cd /data/local/tmp
flashlmdd:/data/local/tmp $ ./v50g8-mroot3

Now you can exit the temp root shell and use 'su' to get a root shell controlled by magisk manager or allow other apps that need root as asking for root permission now works.
You can even re-enable selinux like this from 'adb shell':
Code:
su -c 'setenforce 1'
The magisk setup from exploit including working permission asking has been fully developed by me, it uses some novel techniques to overcome the limitations caused by magisk run from a temp root instead of being integrated in boot process as a service.
TIPS FOR BETTER STABILITY OF THE EXPLOIT
The exploit works based on use after free, that means it depends on state of memory heap and how it changes during exploit time.
That means there is some portion of unpredictability and a chance that something else is overwritten than hoped for by shaping the heap.
So to get best results, one should stop anything that could run in background, like:
set airplain mode, turn off wifi and bluetooth so there is no data connection at all
set "Stay awake" to ON while charging (i.e. using adb shell) in developer options
disable auto updates of system and apps
debloat your system so useless apps do not run in background
reboot your phone having all the above
wait two minutes after boot up with phone unlocked, screen on connected to PC via usb cable having 'adb shell' already active (checking with 'uptime' command)
start the exploit
after getting root shell and succesfuly starting magisk, do not forget to properly exit the temp root shell by use of 'exit' command two times, so the 'adb shell' with the exploit is ended with the rest of clean up
CHANGELOG
2020-05-11 : Initial release (V500N20m-testJ) supporting V500N20m all Korean variants
2020-05-16 : multiple targets supported (v50g8-root)
2020-05-20 : v50g8-dump tool to dump kernel space memory available in G8 thread
2020-05-24 : implemented support for magisk start from the exploit (v50g8-mroot), added support for V50 Sprint with 2020-01-01 security patch level
2020-06-10 : fixed problem when V50 rebooted/crashed soon after obtaining temp root shell, released as v50g8-mroot2
2020-06-23 : hopefully stability improved even more with V50 allowing stable magisk start from temp root, released as v50g8-mroot3

Ok guys, OK!!!!
Here is a guide made for noobs for Root (download, extract and copy root file inside platform tools folder) and Backup in it, using Adb Platform Tools
Root and Backup V50 Korea
1. Download LG V50 Root (extract it and copy inside platform tools folder), Platform Tools ADB and LG USB Drivers 4.4.2 and install it
https://forum.xda-developers.com/v5...g-v50-temp-root-exploit-via-cve-2020-t4098077
https://www.mediafire.com/file/mu78ydkoalgfzyd/platform_tools_adb.zip/file
http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
2. Connect USB then Enable Developer Options and USB Debugging and enable Stay Awake Screen
3. Turn off wifi, data, bluetooth restart phone, unlock screen and let it 1 minute to load all processes
4. Run Power shell command from inside platform tools folder (SHIFT+right mouse and open power shell here) and type cmd and hit enter
5. Run command - adb devices - a pupup should appear on your phone - tap Allow and Remember it on your phone!
6. Run one by one the following commands
adb push V500N20m-testJ /data/local/tmp
adb shell
cd /data/local/tmp
chmod 755 ./V500N20m-testJ
./V500N20m-testJ
7. When rooted you will have this lines in terminal
[*] Launching privileged shell
root_by_cve-2020-0041:/data/local/tmp #
If root is not achieved or phone restarts by itself repeat from step 3
Backup Important non KDZ Stuff like IMEI
1. Download this file backupselected.sh and move it inside your adb program This is already pushed to Platform Tools folder so ignore it
https://www.mediafire.com/file/gh00t76n4ctc061/backupselected.sh/file
2. Run this command from cmd
adb push backupselected.sh /data/local/tmp
3. Obtain Temp Root and from root shell run these
chmod -R 777 /data/local/tmp
./backupselected.sh
4. Backup will be saved in Download folder on your phone
Usefull Commands - Maybe @j4nn can help us with more usefull commands
rm *.* - delete all files
rm -rf (folder name) - delete that folder
adb push (folder or file name) /data/local/tmp - copy that folder or file name to that /data/local/tmp address
cd /data/local/tmp - then - pm install (appname) - installs it

Thank you. Can't wait for the G8 root guide!

Excellent someday we will have the Bootloader unlocked and for being to install the R
ags

Thank you and all other contributors for the donations.
I've updated the first post (not only the donations list but added some more clarifications too).
Please note, as discussed since beginning with @Inerent, only the temp root exploit has been supposed to be implemented by me.
There is however available an engineering booloader, that may eventually allow to unlock bootloader after flashing from temp root.
This needs to be tested first and can involve some risks to brick the phone.
I do not own any LG phone (and do not even want one), so I am not doing that, sorry.
But I've already checked few things regarding the engineering bootloader and I can conclude, that it could be compatible in the sense that it most likely would not brick the device.
The reason I see that comparing stock firmware ABL image and the eng bootloader (aka ABL) seems that both use the same signing root certificate and they both have identical OU info in the signature certificate:
Code:
OU=07 0001 SHA256,
OU=06 0000 MODEL_ID,
OU=05 00000000 SW_SIZE,
OU=04 0031 OEM_ID,
OU=03 0000000000000001 DEBUG,
OU=02 000A50E100310000 HW_ID,
OU=01 000000000000001C SW_ID
If it would work with android 10 is another question though.
Please find attached source for split utility, to get some parts of the image likely to start with a signature certificate.
Those parts then can be converted to text form representation of the certificate via following command for example:
Code:
openssl x509 -in LUN4_abl_a_COM3.img-001238 -inform der -text -noout > LUN4_abl_a_COM3.img-001238.txt

Yes, Jann, thats true. But thx for helping us with some advices. I hope we are a big community (also users are coming from LG v30 and V40) and will figure this out, or rise another bounty if not.
Thx for helping us!

$20 donation sent to @j4nn from me. Thanks for the hard work.

@AngryManMLS, thank you for the donation. Updated the first post.

LG G8

It seems this lg g820UM is the code for all USA carriers and Canada and should work for all like for koreans
If you do March root it will be compatible with February or January? If yes then pick March firmware.

Please note, if the exploit works with March firmware, it does not make it compatible with any other older firmwares, even if they are vulnerable.
The kernel build (binary image) is different there, i.e. it would need different offsets in the exploit to succeed.
The reason for selecting March security patch level with LG V50, i.e. the V500N20m firmware version, has been in order to exploit the newest still exploitable firmware.
The bug has been fixed in LG kernel since April security patch level, so using March fw allows you to use the latest still vulnerable and the most up to date fw for the temp root.
For other targets like the G8 might be useful to select other fw version if there are multiple variants that would use identical kernel binary image, possibly even not having a downloadable fw release for a variant, while existing for another variant (this may be a case if phone variants have identical or nearly the same hw).

The difficult thing is that the G8 variants are all over the place with which firmware/security patch they are on. My T-Mobile variant (G820TM) is on January 2020 meanwhile say the Verizon variant (G820UM) is on February 2020. So it's a mess which pretty much tells me each variant will need to have it's own exploit made for it.
Edit: Just found out the G820UM just got the April security update. KDZ isn't out yet for that.

Hello, I've been talking to inherent on telegram; I think he sent you some of my outputs / logs. I'm sorry I haven't been able to donate as I'm unfortunately not old enough to do so. I've got a Sprint g8 which is stuck on the Android 10 beta on November patch. If you adapt this for other g820um variants, will it likely work with my patch or not?

@AngryManMLS, most likely April security fixed the bug making it not exploitable anymore.
Yes, each kernel build/image would need specific support in the exploit.
@antintin, I need the binary image of kernel used in the firmware that is running the phone we would target with the temp root exploit in order to develop support for it.
Is your Android 10 beta on November patch firmware downloadable anywhere?
Or can you flash any other firmware?
Can you say which G8 model/carrier would have identical hardware to your Sprint G8, while having a downloadable fw?

Well I'm not entirely certain, maybe I can ask vl48. I think any g820um should be fine though. I doubt there is any beta kdz available to download, however. I unfortunately can only go on the final pie version or November patch beta 10 on my Sprint. My updates are broken :

After the temp root, can we flash Magisk patched boot img to /dev/block/bootdevice/by-name/boot_a or something like that? Does it still work after a reboot

@quantan, most likely not, due to dm-verity/AVB 2.0 - it is a temp root...
Magisk (with possibly limited functionality) may be eventually started from the exploit, but it seems not to work yet...

Would be good to at least have android 10 on the Australian V50 but we can't even get that.
Will never buy lg again.

That is not LG fault, is your carrier one. Wait patiently, pretty soon all our problems are resolved.

I have to agree with you on this one. Right now, LG is getting it's lunch eaten by many Chinese OEMs and their bleeding cash in the smartphone business. LG latest "FLAGSHIP", the V60, is a d*** joke when comparing it's 60Hz screen refresh rate to any new smartphone. It's selling for $809.99 new on Tmob and their already selling for less than $700 on Ebay. By end of summer, $390?
I too "Will never buy LG again!".
BTW, I have an Essential PH-1, admittedly old hardware but I'm already running Android 11 DP4 as a daily with very few problems. The V50 won't see 11 for what....... 18 months?
