[APP] Configurator - partition/wipe/backup/restore sd card, other tedious tasks

I wrote this to help when I'm flashing roms and thought I'd share. Let me know what you think - comments, suggestions, fixes.
This is a batch file that gives a menu to perform the following functions:
Code:
echo [1] Edit user.conf
echo [2] Swap status
echo [3] Turn Swap On
echo [4] Turn Swap Off
echo [5] Set swappiness
echo [6] Memory Status
echo [7] Partition SD Card
echo [8] Mount SDCARD in recovery
echo [9] Unmount SDCARD in recovery
echo [10] Repair EXT partition
echo [11] Erase EXT partition
echo [12] Backup EXT partition
echo [13] Restore EXT partition
echo [14] Push lockscreen image
echo [15] Reboot device to recovery
echo [16] Reboot device
echo [17] Wipe device <--- May be buggy
echo [99] Exit
Partitioning is done by using 51dusty's sdparted.
v1.1
Added Repair EXT partition
Added Wipe device (may be buggy)
Extract config.bat to your adb directory (containing adb.exe and AdbWinApi.dll) and run it.
If you aren't familiar with adb, check this thread here.

Hi Phillip, this looks like it has some promise. Can you give some more specifics (commands) for the noobs (like once you open ADB, what then?), or, does a menu come up? I am at adb remount/successful. now what? Thanks.

All you have to do is run config.bat, don't run adb. Type the number of what you want it to do.
Here's some more explanation of what this does, minus the obvious ones.
[1] Edit user.conf
This will automatically pull the user.conf file and open an editor, then automatically put it back on your phone after you make your changes and save.
[2] Swap status
[3] Turn Swap On
[4] Turn Swap Off
[5] Set swappiness
This asks for a value then sets the swappiness to that value.
[6] Memory Status
This shows how much RAM and swap is available and how much is in use.
[7] Partition SD Card
This asks what filesystem you want (EXT2, EXT3, EXT4) on your SDcard, and how big you want the swap partition to be, then formats the card have a FAT32, EXT?, and Swap partition.
[8] Mount SDCARD in recovery
This gives your SDCARD a drive letter in windows while the phone is in recovery mode.
[9] Unmount SDCARD in recovery
[10] Erase EXT partition
[11] Backup EXT partition
This copies the files in your EXT partition to a folder on your computer.
[12] Restore EXT partition
[13] Push lockscreen image
This takes a picture you put in the same folder as config.bat and makes it the background image of your lockscreen.
[14] Reboot device to recovery
[15] Reboot device

Yeah, this is gonna be sweet when I get some time to play around with it. If I have ?'s would you prefer PM's or in open forum?

This looks awesome. Do you have to already have apps2sd on your mt3g for use of step 7? Or is this just an easier way to do so?

7 is to create partitions on the card, then if you flash a rom that uses apps2sd it'll use that ext partition. It uses sdparted to create the partitions, which I think has become standard on most roms. If you flash a rom without it, you can put it on there using the link the first post.

CPU status readings
Hi Phillip, I'm having a lot of fun with your configurator. I would like to ask your opinions on some things related to CPU speed. To that end, I have enclosed the user.conf text I ran, below. The first question is, though: do you have an opinion as to whether the Overclock Widget app causes any potential conflicts or issues? If so, I will get rid of it. My sense from communicating with Mike Taylor on the JACxROM thread is that the ROM more or less sets the CPU automatically. Next, as I understand it, if sacrificing a bit of battery life is acceptable, then the minimum frequency can be set higher, and in one of his last posts he recommended 245760. From what I am attaching below, I am not savvy enough to know exactly what I've got going here. The terms "scaling min freq" and "default" are a little bit beyond me. Bottom line: is the lowest setting currently 128000 or 245760, and is there really any harm in having it set to this level or even higher? I'm almost always plugged into some power source, so battery life does not concern me. Finally, please explain what this means at the bottom of the reading: "percent cpu usage before going up a speed step". Thanks...

I'm glad you're getting use out of it. I've never used the overclock widget, as you said, you don't really need it because the rom does it for you. I set the minimum cpu to 384000 and up threshold to 30 and it stays speedy.
The up threshold - the percent cpu usage before going up a step means how much of the cpu do you want to get used before it speeds the cpu up. I set this at 30. I really don't know if these settings do any damage, but it runs fast. I'm sure the battery takes a hit, but my phone stays plugged in a lot.
For the user.conf file I make these changes:
compcache_en=0
cc_backingswap_en=0
linux_swap_en=1
swappiness=40
scaling_min_freq= 384000
up_threshold=30

Sorry, I think I'm doing something wrong. I just changed those values, hit "enter", x'ed out of the cmd screen, reopened, entered "1", but the values did not change. Is there a final step I am missing? Do I need to click "save" in the drop down of the cmd screen instead of "enter" on the keyboard?

I see what happened. You edited the temp file that gets put on your computer and saved it, but closed the command window before it was put back on your phone. After saving your edits, you have to choose 'exit' from the file menu. That'll exit the editor, then put the changed file onto your phone and return you to the menu.
After editing:
alt+f (file menu)
s (save)
alt+f (file menu)
x (exit)

OK, that was beyond easy. Thanx again. One last question (for now): I know even less about the whole compcache/linux swap thing than I do about CPU settings. However, I think I get it that you either use one or the other, and in post #9 I'm assuming you're using the linux swap and not compcache. Can you explain why you chose one over the other? I know there's all sorts of debates, just wanted to hear your thoughts on the subject.

I use linux swap because I'm running jacxheroski 2.1 (I tried 2.2a/b/r4 and it was too buggy and rebooted) and compcache doesn't work on the MyTouch on 2.1. I really don't know anything about how each works and how they are different, I just know linux swap works for me.

Good enough. Yup, I'm gathering as I read more, "to each his own". Mike recommended the settings he put into the JACxROM, so I'll go with the master's recommendations. Thanks again.

new info
Hi Phillip, long story shorter, Mike changed some things up on the earlier JACxROM version, and based on what he said and what I'm attaching, it appears linux swap vs. compcache is the way to go on that one. He recommends a 64 MB swap partition. I am not able to tell what size it is. Can you? Your configurator is really fun but still a bit beyond me...

Using swap automatically uses the full swap partition (whatever size you set when you formatted the SD card).
Use "[6] Memory Status" from the menu.
Your total swap size will be across from "Swap:" under "total" heres mine (62676):
Code:
total used free shared buffers
Mem: 97852 96120 1732 0 620
Swap: 62676 25528 37148
Total: 160528 121648 38880

any chance of this being converted to linux-friendly ?!
I might be able to do the work to convert the script to linux-friendly, if mr hooper would allow it!

Hi, I'm new to Android.
I installed the SDK, and put your script in ../android/tools
Yes, I put ../android/tools in my path (winxp).
I'm running Cyanogenmod 4.1.999
when I run your script, it says 'Device state is unknown'.
I can mount my sdcard as a removable drive when I connect it via usb to my computer. Did I not install something that I needed to?
Also, does anyone know where Cyanogen put the user.conf in his mod?
Thanks in advance and sorry for my noobitude.

If you are in recovery mode it should say device is unknown. This is normal. If the phone is booted and shows unknown then you'll want to be sure you installed the usb_drivers from the sdk properly.

Thanks, that worked.
I have 2 computers, drivers would not update on one, but the were able to install on the other. Can't figure out why.
I'm using cyanogenmod 4.1.999, and it says that I don't have a user.conf, and it also says 'system/bin/swap not found'.
This is what it shows when I press 6 (memory status):
total used free shared buffers
Mem: 98140 96300 1840 0 432
Swap: 96812 24520 72292
Total: 194952 120820 74132
Device is booted.
Is it normal for that much memory to be used (I have the 192mb Mytouch)?
P.S., thanks for the Configurator app!

[Application] gstreamer for Eclair, Froyo and Gingerbread

Here it is the gstreamer for your rooted android phones. I have made two flashable zip files:
gstreamer-0.10_gingerbread.signed.zip for android 2.3 (gingerbread)
gstreamer-0.10_24-11-10.signed.zip for android 2.1 and 2.2 (eclair, froyo)
I strongly suggest you take a backup of system partition before you flash as it contains third party shared objects like glib and oil.
For your convenience I have included a init script at /etc/init.d/99rtpstream which will launch either "/system/sd/rtpstream.sh" (eclair and froyo) or "/sd-ext/rtpstream.sh" (gingerbread) if they exists at boot time.
Gstreamer is a very flexible multimedia frameworks and it supports windows, OpenBSD and Linux. More information can be found in http://gstreamer.freedesktop.org.
This build is targeted at audio processing as I could not get the videooutput (surfaceflingersink) working. Patches are welcome please see the bottom of the post for sources.
Turns your mobile into wifi speakers
At home I have a htpc which plays videos on the TV. However occasionally I would like to use my android mobile as wifi speakers with a pair of headphones so I will not disturb others. This setup also give me the freedom to roam around the whole house whilst listening to favorite music/radio or just anything being played on the htpc. I found it rather convenient to listening to online radios.
Step 1 On your android mobile
Login to your mobile either via adb or ssh and run the following commands in sequence:
Code:
export GST_PLUGIN_PATH=/system/plugins
export GST_REGISTRY_UPDATE=1
export GST_REGISTRY=/system/sd/gst-reg.bin
AUDIO_CAPS="application/x-rtp, media=(string)audio, clock-rate=(int)90000, encoding-name=(string)MPA, channels=(int)2,rate=(int)44100, payload=(int)96, endianness=(int)1234"
gst-launch-0.10 udpsrc buffer-size=4096 port=6500 ! $AUDIO_CAPS ! rtpmpadepay ! mad ! audioconvert ! audioflingersink sync=false latency-time=100 blocksize=16384
Replace "/system/sd/" by the correct place where your sd card is being mounted, for aoss build this is likely to be "/sd-ext/".
Step 2 On your pc
Here are instructions for windows and linux only, for other platforms please refer for online help to setup correct source and parameters.
{windows}
Install gstreamer 0.10.7 from http://code.google.com/p/ossbuild/downloads/detail?name=GStreamer-WinBuilds-GPL-x86-Beta03-0.10.7.msi
and run the following command from the console
Code:
cd "C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.7\bin
gst-launch.exe directsoundsrc blocksize=4096 ! audioconvert ! lamemp3enc target=1 cbr=true bitrate=128 ! rtpmpapay ! udpsink port=6500 host=ANDROID_PHONE_IP
Replace ANDROID_PHONE_IP by the ip address of your android mobile
{Linux}
Code:
gst-launch-0.10 pulsesrc device=output.monitor ! "audio/x-raw-int,channels=2,rate=44100" ! audioconvert ! lamemp3enc target=1 cbr=true bitrate=128 ! rtpmpapay ! udpsink port=6500 host=ANDROID_PHONE_IP
Replace "ANDROID_PHONE_IP" by the ip address of your android mobile and replace "output.monitor" by the name of your default pulseaudio output monitor device.
Automate the process
If you are happy with the whole thing, I would suggest put the script from Step 1 into /etc/init.d/ so it will start automatically at boot time. However you will not be able to start/stop gstreamer easily without touching the adb or ssh console. I ended up adding a loop to check a particular file on sdcard with the following script (save it to /etc/init.d/ as 99rtpstream.sh and make it executable)
Code:
#!/system/bin/sh
export GST_PLUGIN_PATH=/system/plugins
export GST_REGISTRY_UPDATE=1
export GST_REGISTRY=/system/sd/gst-reg.bin
AUDIO_CAPS="application/x-rtp, media=(string)audio, clock-rate=(int)90000, encoding-name=(string)MPA, channels=(int)2,rate=(int)44100, payload=(int)96, endianness=(int)1234"
killall gst-launch-0.10 > /dev/null 2>&1
while [ "$test" = "" ]; do
if [ -f /system/sd/rtpstream.nostart ]; then
sleep 5
else
gst-launch-0.10 udpsrc buffer-size=4096 port=6500 ! $AUDIO_CAPS ! rtpmpadepay ! mad ! audioconvert ! audioflingersink sync=false latency-time=100 blocksize=16384
sleep 5
fi
done
Replace "/system/sd/" by the correct place where your sd card is being mounted, for aoss build this is likely to be "/sd-ext/".
Basically it will not start gstreamer if there is a file called rtpstream.nostart on sd card.
I have also created 2 scripts on sdcard that can be used with gscript lite so I can start/stop gstreamer from gscript without touching adb or console.
start script (save it to sdcard as rtpstream-start.sh and make it executable)
Code:
#!/system/bin/sh
rm /system/sd/rtpstream.nostart
Replace "/system/sd/" by the correct place where your sd card is being mounted, for aoss build this is likely to be "/sd-ext/".
stop script (save it to sdcard as rtpstream-stop.sh and make it executable)
Code:
#!/system/bin/sh
busybox ps | grep gst-launch | grep -v grep | awk '{print $1}' | xargs kill
touch /system/sd/rtpstream.nostart
Replace "/system/sd/" by the correct place where your sd card is being mounted, for aoss build this is likely to be "/sd-ext/".
In gscript you can create 2 scripts with root permission and one to use the start script and the other to use stop script.
Other considerations
Streaming realtime udp over wifi when screen is switched off proved to be problematic (voice chopping) under android as most of the factory wifi driver is too aggressive on power saving. The solution is to change the default power saving mode to something like PM_FAST for some broadcom chips. This will involve recompiling the kernel. If you are using wildfire/buzz you can try my customised kernel from here http://forum.xda-developers.com/showthread.php?t=967746.
Sources
Most of the gestreamer sources including dependency libs come from http://github.com/prajnashi/ and it was ported for andriod 1.5 and as such the gstreamer android plugin is not working at all and I had to resort to this http://github.com/jahrome/. Unfortunately I could not get the video sink (surfaceflingersink) working, patches are welcome.

[WEBTOP] GenTop2-20120509 (Beta) - Next Generation Gentoo Webtop Replacement

[size=+1]Introduction[/size]
What is GenTop2?
GenTop2 is a full-fledged Gentoo Linux able to replace the original Motorola Webtop. It is faster, fully-customizable and gives you the power of a complete Linux system on a mobile phone. It is a peek into the future of mobile computing!
Thanks goes to kholk, who did the original GenTop, otherwise I would have long given up.
Why use Gentoo Linux as WebTop?
Programs are fully optimized for the ARMv7a CPU contained in the Atrix.
Thus the whole system is faster and more responsive.
No shackles put around the WebTop by Motorola.
You can install any program (which compiles on ARM).
All software (except X11) is fully up-to-date.
You remember old times with desktop computers having far slower CPUs and less RAM than your phone and you wonder what you can do with this pocket computer.
Why NOT use Gentoo Linux as WebTop?
Gentoo is huge because it must install all development files.
The system and all programs must be compiled on the phone. How crazy is that?
Firefox could not be built. But, there is a smaller replacement.
Why bother using a phone, when you already have a notebook?
Working and Installed Applications
X11 via WebTop or HDMI (with hdmi-hack)
Xfce4 with thunar file manager
midori web browser with Flash player
claws-mail client
audacious
evince (pdf viewer)
ssh daemon
rxvt terminal
aiw Android In-A-Window!
Sound output via Android media system.
All are very light-weight Linux applications perfect for a small system.
Not Working:
webtop-panel (system status bar on top)
non-flash video playback ?
Installable as binary packages:
firefox (renamed to Aurora due to trademark stuff), approx 30 MB.
thunderbird (renamed to Earlybird due to trademark stuff), approx 44 MB.
libreoffice, approx 250 MB.
abiword, pidgin, emacs, texlive,
and many more, drop a note for more wishes here. However KDE is just too large.

GenTop2 Space Requirements, Disk Speeds and a Note About WebTop2SD
Gentoo is very large because packages contain all development files. This cannot easily be changed, therefore one must work around the space limitation of the /osh partition in some way.
I did some "disk" performance measurements using bonnie++ (see [1] for full info). Here the through-put results in short: /data (ext3) 20,800 KB/s read and 6,200 KB/s write, /sdcard (fat32) 21,500 KB/s read and 8,000 KB/s write, /sdcard-ext (ext3) 12,300 KB/s read and 4,200 KB/s write, /sdcard/loopback.img (ext3) 16,150 KB/s read and 4,400 KB/s write.
One way to go would be to require webtop2sd, however, GenTop2 does not support webtop2sd because the read/write speed of the internal sdcard is much faster than on the external sdcard. Thus I tried to install as much on the /osh partition as possible and move directories onto other partitions as necessary, leaving symlinks behind. WebTop2SD also requires dpkg for some reason, which Gentoo does not have.
Therefore, it's pretty unavoidable that you do some space management yourself.
I have decided to utilize the /preinstall partition for /var. I'm not fully sure that this partition is unused on every Atrix released, but I guess in most cases it contains only provider specific bloatware that people don't want anyhow. On my Atrix it contained some car racing game, which I find hilarious to play on a mobile phone.
Anyway, the /preinstall partition is 300 MB and perfect for /var if reformatted to support many small files. The /var/db/pkg/ directory contains lots and lots of small files describing the installed packages. See the installation instruction for the mkfs line.
I also decided to require some extra ext3 partition for further program, data and portage files. It is needed anyhow to install further programs, which is what most people want to do. The /data partition would be the obvious choice and for that reason the first GenTop2 put files in /data/osh/. However, /home/ is also on /data by default and it gets pretty annoying when your home directory is full.
The only alternative to /data is either a partition on an external sd-card or a loopback mounted file-partition on /sdcard/, both are not as fast as /data (/cache cannot be used as it must be wipeable). So there really isn't much choice left except for external storage.
The main GenTop2 tarball puts 630 MB in /osh (leaving 145 MB free) and 178 MB in /preinstall (with 150 MB free), which must be mkfs formatted.
The portage GenTop2 tarball puts 1460 MB into /mnt/gentoo/ of which 475 MB are data files from /osh/usr/ and 810 MB are the portage tree.
[size=+1]Steps to install GenTop2:[/size]
There are some complications involved when using faux123's kernel, because it only contains ext4 filesystem modules and explicit mounting of ext3 will fail. The ext4 module will however mount ext3 filesystem without problems.
use adb shell and get root:
Code:
$ su
# cd /osh
# mv etc etcx
# reboot
Reboot. The above will disable the webtop.
Download http://kristallsturm.de/GenTop2/GenTop2-20120509.tar.gz (275MB) and put it onto /sdcard via USB or adb push.
use adb shell to overwrite the existing WebTop:
Code:
(first we delete /osh)
# cd /
# ls bin
bin: No such file or directory
(this tests whether the old webtop is disabled)
# rm -r osh/*
# ls osh
(should be empty)
(next we disable and reformat /preinstall)
# mount -o remount,rw /dev/block/mmcblk0p12 /system
# mv /system/bin/load_pia.sh /system/bin/load_pia.sh.disabled
# umount /preinstall
(depending on your ROM this might fail. ignore this problem if the following format works)
# mke2fs -m 0 -i 2048 -j /dev/block/mmcblk0p17
# mount -t ext3 /dev/block/mmcblk0p17 /preinstall
(for faux kernel: replace ext3 -> ext4 in above line)
(now we unpack the main tarball)
# df
(/osh and /preinstall should be almost empty)
# cd /
# tar xvzf /sdcard/GenTop2-20120509.tar.gz
# sync
(begin extra for faux kernel: we change ext3 -> ext4)
# sed -i s/ext3/ext4/ /osh/ubuntu.sh
(end extra for faux kernel)
# sync
# reboot
Once rebooted you will get an X11 login on the HDMI connection or you can access the phone via ssh.
Account Passwords:
root / atrix
adas / atrix
To make GenTop2 more useful and to compile/install further packages you currently must have an external sd-card (or someone must devise a method to use a loopback device).
I have partitioned my external sdcard using a desktop computer into the following two partitions:
/dev/block/mmcblk1p1 (remainder)
/dev/block/mmcblk1p2 (4.0 GB, formatted ext3)
Advanced: (Actually most of this stuff is advanced.) You can also use the new GenTop to partition the external sd-card. Open a terminal, and use something along the lines of:
Code:
# fdisk /dev/block/mmcblk1
(partition it, see further description of fdisk on the net)
# mkfs.ext3 -m0 /dev/block/mmcblk1p2
The boot-up script /osh/ubuntu.sh will mount /dev/block/mmcblk1p2 to /mnt/gentoo. This place is referenced by /usr/portage, /var/tmp and /preinstall/usr and will enable emerge if you install the second GenTop2-portage-20120509.tar.bz2 tarball.
Download http://kristallsturm.de/GenTop2/GenTop2-20120509-portage.tar.bz2 (124MB) to /sdcard/ using any method.
Use adb shell or a terminal on the desktop
Code:
$ su
# cd /
# tar xvjf /sdcard/GenTop2-20120509-portage.tar.bz2
Note: If you trust your network connection, you can also download and unpack simultaneously (without saving) it using:
Code:
$ su
# cd /
# wget -O - http://kristallsturm.de/GenTop2/GenTop2-20120509-portage.tar.bz2 | tar xvj
[size=+1]Installing further software[/size]
How do I install applications in Gentoo?
- Read http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1
- Read http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=3
I have set up a portage overlay "atrix-overlay" which unmasks many packages and includes some custom patches required for compilation on arm. It is included in the main tarball and automatically synced alongside "emerge --sync". Most updates will now be performed via this overlay.
See https://github.com/gendol/atrix-overlay for details.
Furthermore, for large binary packages like firefox, thunderbird and libreoffice I have set up a binary package repository with the same USE flags as the atrix-overlay. These are built using cross-compilation on my desktop computer.
See http://kristallsturm.de/GenTop2/packages/
To force installation from binary packages use emerge -G <package>. See the list of "Installable as binary packages" above.
[size=+1]Miscellaneous Questions[/size]
Why no thumb instructions?
- I did a speed test of cryptography functions and thumb instructions were approximately 10% slower than usual ARM code.
Where was GenTop2 compiled?
- Most of the system was fully compiled on my own Atrix. Larger binary packages are compiled on my desktop using cross-compiling.
Why is X11 not up-to-date?
- The only xorg driver I could get working is the one on the original Webtop, and that requires an older version of X11.
Why is udevd not running?
- If you look at logcat there are lots of the following messages, some of which are due to udevd. Disabling udevd reduces (but does not eliminate) these messages and probably also some unnecessary background process that draws battery.
NetlinkEvent: NetlinkEvent::FindParam(): Parameter 'UDEV_LOG' not found
NetlinkListener: ignoring non-kernel netlink multicast message
NetlinkListener: ignoring non-kernel netlink multicast message
[size=+1]Reinstalling the old WebTop[/size]
Some people on the forums struggled to reinstall the old webtop for some reason. It shouldn't be that difficult and I created a tarball of the original Webtop WT-1.2.0-133_38. These instructions were not tested by me:
Download http://kristallsturm.de/GenTop2/WT-1.2.0-133_38.tar.gz to /sdcard/ using any method.
Use adb shell or a terminal to disable mounting of webtop:
Code:
$ su
# cd /osh
# mv etc etcx
# reboot
Use adb shell to unpack original tarball into /osh:
Code:
# cd /
# ls bin
bin: No such file or directory
(this tests whether the webtop is disabled)
# rm -r osh/*
# ls osh
(empty)
# cd /
# /sdcard/WT-1.2.0-133_38.tar.gz
# sync
# reboot

It is a good job. I try this. Thank you.

This is a very agressive aproach. /osh dose have some Moto magic sauce in it. How well can you drive the screnn with a stock X system? Most of the cutesy features from WT I can live w/o, but the "phone"app really is usefull. Seams like this would be worth the effort to figure out.
If I was using a less "pure" setup (spinning up X and the phone app in Motos osh) then bringimng up the desktop in Gentoo, how would that compare to oither the same concept with other distros?
Please post on. I think this is the first time somebidy has run a non /osh X. Would love to see if it really can be done.

Thanks for pointing that out. Yes, the approach is radical, but not as aggressive as you may think. All the "magic sauce" in /osh lives in /osr/usr/local/ and all of that is retained. The only problem is that some dynamic link libraries are missing, but most of these problems can be fixed.
They actually had to be fixed because the GenTop2 does need to send some magic signals to Moto's PortalApp/DockService to work correctly. This is done using the /usr/local/bin/rmtest tool via the "fbcp" instance of dbus.
Other than /osh/usr/local/, /osh is really just Debian.
With the phone app, you mean the green phone button? I just tested that, it can be added. The phone button is nothing but a .desktop mime file, which calls one of the magic apps /usr/local/bin/androidlauncher. And it popups up in the aiw display.
I even tested the HD Media Center laucher and that too worked without problems. That really should be included in the next GenTop2 tarball.

I guess I don't understand what you mean with a non /osh X. GenTop2 does run X11 and you really need to replace the system libaries to get a well-working Gentoo.

Great job! Does this work with cm rom's aswell or only with blur based ones? As another fact, we could use distcc or crosscompile distcc to compile most of the stuff, actually even a crosscompile binhost would be doable for several packages. One more thing, we could probably use an .img file on the internal sdcard partition, that would be ext3/4 formatted instead of using the external sdcard (but probably its better and safer to sue the external card, due to the flash wear)
edit: so i tried it on my atrix with nottachtrix rom installed, it starts fine and seems to work rather well, i only saw two to me rather annoying bugs:
1. somehow the X server thinks that my tv (1080p lg) has a virtual size of 1366x768 and will not allow to use the 1920x1080 resolutions that are in the TV's EDID and that the system puts into the xorg.conf file aswell as it shows in the Xorg.0.log
2. the atrix's screen stays on all the time in the "normal mode" and if one uses the mouse on the gentop its moving and functioning on the atrix's screen aswell (ie you can launch apps by accident with the mouse in android)
I do not know if these are issues with nottachtrix or something else, but for me on the "normal webtop" 1080p worked on this same TV.
here the xorg log: http://dl.dropbox.com/u/24268926/Xorg.0.log

Really nice, installing it right now!
Does flash work on Midori?

I don't know about CM7, you'll have to try to replace the Linux system like moto does it.
The X11 screen size defaults to WebTop resolution 1366x768, but you can change that to 1920x1080 by editing /etc/X11/xorg.conf. The first thing to try is to comment out all Modelines and let EDID detection do the work. But for that a monitor must be present, so you need to Zap (Ctrl+Alt+Bckspace) your X, and that brings up the dual input problem.
I also use nottach's ROM. The dual input problem happens when something in motorola's magic communication goes wrong. I have not been able to figure out how in particular moto disables input on the touchscreen. For me it works most of the time. I also have all the Modelines in xorg.conf enabled, because they fit my monitor.
I didnt really focus on Flash, yet. But as it works on the original Webtop, you should just be able to copy the plugin files.

Can't get Midori working .. Got network (via ping), but no web browsing
EDIT: Solved by disabling proxy settings inside Midori

i haven't run gentoo in over 10 years but this is tempting!!!!!

1) use ADB and first post
2) Gentoo Portage - it's command line but very easy

Hmm, anyone using this with webtop over HDMI? I get the login screen, but the webtop touchpad thingie doesn't come up so it's impossible for me to log in.

Yes. The touchpad thingy is also an open end. I have no idea why it doesnt come up. The GenTop2 tries to do everything in the same way as the original one, but for some reason that doesnt appear.
I guess the touchpad is some Android program part of DockService or PortalApp, which drive the Webtop switch. But I havent debugged how to activate it.

To extract a .tar.bz2 you use tar xvjf ...

three items one that caused some grief, but other than that this has lots of cool potential!
I have a stock rom with root.
1. resolution was pretty screwed up. I did try to adjust the resolution, but it was locked into one setting.
2. flash isnt installed on the browser so many websites where disabled.
3. I could not get AIW to start.
I see you answered #1 in a previous post. But I think all three of those items are minimum requirements to replace webtop. BTW great job again! Its seemed much faster than the webtop app.

2. Try to copy the flashplugin from original webtop(not sure if it works with midori)
3. aiw works fine try to reboot the phone

Took me a while to get this all running, but it's great now it is. Have this over Nottachtrix 1.3.1. Everything installed and works fine!
Cheers!

When my phone turns on and gets to the preparing sd, it takes forever. Does this happen to anyone else?

anyone tried to emerge chrome/chromium?

[I9001] [SCRIPT] Zram script for arco's ICS build

Hello everybody,
I thought that ICS was a little bit slow on my SGS+ so I tried to tweak it.
This is when I came across the option compcache in the settings -> performance menu.
Only I found this option isn't w orking yet in arco's alpha 3 build, or isn't working anymore.
Either way I found out that zram0 is present on the device, so I created a little script with which you can set-up Zram.
Just put it somewhere you can browse to with Terminal Emulator.
Also make sure it's permissions are set to rwx-r-x-r-x.
After you set the permissions right, just execute with: ./zram start
Or if you want to stop the swapping again just give in ./zram stop
This is the code for the script:
#!/system/bin/sh
#
# Zram manager
# koudumrulez{at}gmail.com (PsychoGame)
case "$1" in
start)
echo 3 > /proc/sys/vm/drop_caches
echo 30 > /proc/sys/vm/swappiness
# get the amount of memory in the machine
mem_total_kb=$(grep MemTotal /proc/meminfo | grep -E -o '[[:digit:]]+')
mem_total=$((0,25 * mem_total_kb * 1024))
# initialize the devices
echo $((mem_total)) > /sys/block/zram0/disksize
# Creating swap filesystem
mkswap /dev/block/zram0
# Switch the swap on
swapon /dev/block/zram0
;;
stop)
# Switching off swap
swapoff /dev/block/zram0
;;
*)
echo "Usage: $0 {start|stop}"
esac
exit 0
You can just call the file zram, and then copy it on you're device for example you're SD.
I only used this script on ALPHA3 build. Maybe it works on others as well, but that's at you're own responsibility.
Greetings Psycho Game

Here I'am again.
There's been a little error from my side.
If you put this file on you're SD-Card you can't set the permissions right.
What I did was putting the file in /system/bin, so the full path would be /system/bin/zram.
I did this with ES File Manager, but you're free to use whatever file manager you like.
After this make sure the permissions are set to rwx-r-x-r-x in the file manager, or in the terminal you can do a "chmod 755 /system/bin/zram" without quotes.
The zram is now useable through executing the command: "/system/bin/zram start or stop".
You can also choose to mount the zram automatically with booting.
In this case you have to make a file called userinit.sh in the folder "/data/local/"
This file needs the following content:
#!/system/bin/sh
/system/bin/zram start
I also set the permissions of this file to 755 with "chmod 755 /data/local/userinit.sh" but I'm not sure if this is neccesary. Anyway it works.
Hopefully somebody can use this script as well. If you do, please leave a comment. Also if you have questions feel free to ask. I will keep an eye on this post.
And the question if this will work on Alpha 4, yes it does.
Greetings,
Psycho Game

Hi Psycho,
thanks for your effort.
I also saw that zRam is indeed not working on the latest Alpha 6 (i use the Galxy W / i8150 Build).
I had a look at your script and some other sources and enabled zRam on my deivce for testing purposes.
My conclucsion so far is, that there seems so be some major problem of interference with an other memory management policy.
Independent from the Size and Swapiness configuration - there is something going wrong hier i think
I watched the systems memory stats through proc/meminfo and free. Once the system is out of fresh memory, it begins swapping. zRam swap then getfs filled up quickly. Now the system gets extremely slow, i also had two restarts (likely in cause of some kernel panics from acute memory problems).
Will be difficult to track down the problem, my guessings so far:
- Interference with LMK, as it only indirectly knows about zRam
- Some kind of io block size might have been set to a bad value for the zram device
- CPU-load through compression simply much to high (unlikely, but have not checked it yet)
.. and plenty other possibilites
ATM, its definitely only a huge decrease in performance for me. What was your experience?
From the technical specs, i guess zRam should behave much better, so i really guess theres going something wrong.

Guess i found a possible reason for the bad performance.
I will write more details when i have the time to.

Just tried the above script on CM9 (build 0814) for Galaxy Exhibit 4G (a sister phone of Galaxy W as I understand it). I ran the script in the Terminal. Initially the performance became very bad after a period of time (especially after opened many apps). It almost looked like zRam made it worse once it got used for some storage amount. However, after I changed mem_total_kb from MemTotal to MemFree, and removed 0,15 for mem_total, the horrible slow down seemed to disappeared (even after I opened 5 apps at the same time).

any further refinements of this script?

"Roll your own" SKINNY MIUI - Revised 09/04/16

Skinny MIUI is all about preserving the good; Working premium drivers for Camera, CPU control, Notification LEDs, Bluetooth, FM Radio etc. while resolving what is bad in the stock offering.
All deletions assume the user has absolutely no interest in being part of the Xiaomi ecosphere. Leave now if that is not you.
This guide applies to MIUI stable versions 7.1.1 thru to 7.2.5 only. Developer, Beta or Eng versions are not good candidates.
STAGE 1:
Boot.img mods: (this is not creating a custom kernel!!!)
The stock boot.img is unpacked, init.d support added and many entries that are not relevant to our hardware removed.
Disabling lines trying to load non-existent services from init.rc, init.mt6795.rc and ueventd.rc etc. stops a bit of churning on each and every boot and frees up a bit of RAM.
There are intentionally no other tweaks contained within the boot.img. All tweaks are done in init.d scripts accessible outside the boot.img.
Note: This boot image made from 7.1.4 will work back to ver 7.1.1 and forward to 7.2.50 / 6.3.31 and is superior to the stock boot images contained in those ROMs.
At this point you can flash the modified boot.img to your phone if you already have a stock MIUI 7.1.1 to 7.2.50 installation that you are going to keep.
If you are going to do a clean install, replace the boot.img in your ROM zip file with this modified one. (backup the original first)
The boot.img is found here: (Now links to folder with all versions available)
https://drive.google.com/folderview?id=0BwdRTuyj12_yRk9Kcm1pZkxuZzg&usp=sharing

STAGE 2:
Full install:
I recommend you install my TWRP 3.02-2 version from here:
https://drive.google.com/open?id=0BwdRTuyj12_yWWp0SUpGV1pzT1k
Before installing your chosen ROM:
Check that the updater script found: \META-INF\com\google\android\updater-script is not going to install Preloader, Uboot (lk), Recovery or logo partitions. If so, edit the updater-script to prevent this happening. This is to reduce the risk of a soft-brick or being locked out of your phone.
Do a factory reset in TWRP (wipe Data, Dalvik, Cache) before installing any ROM.
Install your chosen ROM. Trying to slim down the ROM before install is an arduous affair which tends to end in bootloops so we leave the original ROM alone in this respect..
Do the install without connecting to mobile or WiFi networks and just skip at screens prompting for network connectivity and creating accounts.
Reboot into TWRP once finished with the initial Setup to avoid Recovery from being deleted on first boot.
Install an updated SuperSU zip package from TWRP recovery - V2.46 to 2.71 work equally well.
Do not install a root package other than SuperSU - most online ones are malware!
Update the outdated and incomplete Busybox installation. I have created a TWRP flashable zip to upgrade to the latest version 1.25.0. This is the second edition which has better binaries and no longer creates symlinks to busybox commands.
https://drive.google.com/open?id=0BwdRTuyj12_yd0s1QmNLRzdveFk
Now install a root capable filemanager (Root Explorer or Total Commander recommended). Open it and gain root permissions. Open /etc/perfservscntbl.txt in a text editor and edit as follows:
Code:
CMD_SET_CPU_FREQ, SCN_APP_TOUCH, 403000
CMD_SET_CPU_CORE, SCN_APP_TOUCH, 1
This will lower the number of cores used and the frequency at which it runs when a screen touch is detected (referred to as Touch Boost) Changes are activated on reboot.
Now create a file named 01_tweaks in the /etc/init.d folder. Change the permission of the file to 0755
Tips on creating scripts:
The EOL(end-of-line) characters must be in Unix format - not Windows. Make sure you are using a text editor that saves in Unix format.
Note also that many script files need a blank line at the end to work correctly. Get in the habit of always doing this whether needed or not.
Any line starting with a # character and anything after a # character on a line is not processed and is referred to as "commented out"
Script files must start with the header #!/system/bin/sh as the first line.
Init.d scripts are processed in alpha-numeric filename order hence the common usage of 01_xxx, 02_xxx format for names.
Copy these lines into the 01_tweaks file: Note: Different values for 2.2GHz cpu and freq limited operation.
Code:
#!/system/bin/sh
### Tweak Interactive CPU Governor
echo 806000 > /sys/devices/system/cpu/cpufreq/interactive/hispeed_freq
echo 85 > /sys/devices/system/cpu/cpufreq/interactive/go_hispeed_load
echo "90 403000:80 806000:85 1326000:90 1625000:95 1950000:99" > /sys/devices/system/cpu/cpufreq/interactive/target_loads
echo 32000 > /sys/devices/system/cpu/cpufreq/interactive/timer_rate
echo 10000 > /sys/devices/system/cpu/cpufreq/interactive/min_sample_time
echo 15000 > /sys/devices/system/cpu/cpufreq/interactive/above_hispeed_delay
echo 20000 > /sys/devices/system/cpu/cpufreq/interactive/timer_slack
### Tweak IO Scheduler
echo deadline > /sys/block/mmcblk0/queue/scheduler ### choose between cfq, bfq or deadline
### Enable this line if using cfq or bfq scheduler only
# echo 0 > /sys/block/mmcblk0/queue/iosched/slice_idle
echo 256 > /sys/block/mmcblk0/queue/read_ahead_kb
### Enable zram swap
# echo 1073741824 > /sys/block/zram0/disksize ### 536870912 = 512MB 1073741824 = 1GB
# /system/bin/tiny_mkswap /dev/block/zram0
# /system/bin/tiny_swapon /dev/block/zram0
### Tweak Entropy to avoid regular depletion of available pool
echo 512 > /proc/sys/kernel/random/read_wakeup_threshold
echo 1024 > /proc/sys/kernel/random/write_wakeup_threshold
#Tweak for wifi router connection issues
#echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
### FSTRIM: Enable once after installation is finalized and then monthly ##### needs an updated busybox installation to work
# busybox fstrim /data
# busybox fstrim /cache
# busybox fstrim /system
Options: Add / replace lines to do the following:
1. freq limit a 2GHz cpu to 1781MHz (recommended setting)
echo "90 403000:80 806000:85 1326000:90 1625000:95 1781000:99" > /sys/devices/system/cpu/cpufreq/interactive/target_loads
echo 1781000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo 1781000 > /proc/cpufreq/cpufreq_limited_max_freq_by_user
2. Full speed 2.2GHz cpu
echo "90 403000:80 806000:85 1326000:90 1664000:95 2158000:99" > /sys/devices/system/cpu/cpufreq/interactive/target_loads
3. freq limit a 2.2GHz cpu to 1885MHz (recommended setting)
echo "90 403000:80 806000:85 1326000:90 1664000:95 1885000:99" > /sys/devices/system/cpu/cpufreq/interactive/target_loads
echo 1885000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo 1885000 > /proc/cpufreq/cpufreq_limited_max_freq_by_user
4. Add a limit to the maximum number of cpu cores allowed to come online (for possible battery saving maybe...)
#Limit max cpu cores available (range 2 - 8)
echo 4 > /proc/hps/num_limit_low_batt
echo 4 > /proc/hps/num_limit_power_serv
echo 4 > /proc/hps/num_limit_thermal
echo 4 > /proc/hps/num_limit_ultra_power_saving
Edit /system/build.prop. Change the line: ro.sf.lcd_density from the default 480 to a value between 400 (everything smaller, more on screen) to 520 (everything larger, less on screen) to suit your taste and eyesight. You can test this out first by issuing the wm density command in a terminal app. e.g wm density 440 will immediately change the density to 440dpi, wm density reset will put it back to whatever the build.prop setting is. Adjust the text size in Settings in conjunction with this to get the best result.
At this point you have a functional set of tweaks that are all tested and proven to provide a battery and performance improvement. There are a lot of detrimental or placebo tweaks out there so be a little bit discerning in what else you add to these tweaks - sometimes less is more. Now is not the time to load up those tweaks!
Do a TWRP backup of System, Data, Boot and NVram partition now to save your efforts up to this point.

STAGE 3:
Now its time to get Skinny: You will need an app that can uninstall and freeze system apps. I use SD Maids App Control feature for this purpose.
Warning: If you intend to use app lock, you will unfortunately need to keep some fingerprint service files. See the post below and a few before it to understand the problem. Thanks to @DarthJabba9 for his work.
I believe that app lock also disables MIUI Optimization if enabled.

First phase is to get rid of the obvious bloat apps and Xiaomi in-house apps....these in the list below are safe to remove.
Tick off what you have removed and reboot each 10 or so deletions and backup, don't try to delete everything in one hit as you will end up stuck at boot.
WARNING: This removes some functionality that may be useful to some users. You either want the function or you don't - it is your finger pressing the buttons!
Some people may choose to keep the MIUI Home Launcher interface. In this case, keep MIUI Wallpaper as well.
Must keep these - Do not delete:
Updater - disable autostarts, do not freeze
Theme Manager - disable autostarts
Security (com.miui.securitycenter) - leave as-is
FwkPlugin
Network Assistant app
MiuiSDK - disable autostarts
AuthManager
Webview (update via Playstore once install finished)
Xiaomi service framework - disable autostarts, freeze app
Definitely O.K to delete list:
Wallpaper Apps:
Android Live Wallpapers
Black Hole
Bubbles
com.android.wallpaper.holospiral
Live Wallpaper Picker
Music Visualization Wallpapers
Phase Beam
Photo Screensavers
*Miui MiWallpaper * keep if also keeping MIUI Home Launcher.
Xiaomi/MTK Apps:
Analytics
Assistant
Back up Home screen layout (cloud backup)
Backup - delete if you don't use it (use TWRP instead)
Battery Warning - deleting this does not affect battery charging or display
Battery Saver - deleting this improves battery life
Blocklist (AntiSpam) - delete if you don't use it
com.miui.mipub
File Explorer - delete (you should already have a root capable file browser)
Find device - use the generic Google version if you really must, not the Xiaomi one supplied.

Note: If you have apps reappear as if by magic, they are being reconstructed from cached information. SD Maid has an excellent "Corpse Finder" function that will delete the orphaned files and prevent this happening. Clear corpses after each reboot.
Second phase is to toggle off the autostarts (receivers) on the apps that do not need to start by default. This is not the same as freezing an app. Some apps will still start by themselves - do not worry too much about this.

Third phase is to clean up left behind folders and files
/data/miui/app/customized/ remove any app folders that you have uninstalled
/data/miui/app/noncustomized/ remove any app folders that you have uninstalled
delete folder /data/miui/mms
delete folder /data/miui/gallery

Establish network connectivity.
If Gapps is required but not installed, download open_gapps-arm64-5.0-pico version. You can install individual extra Google apps at any stage later on.
Go through all MIUI Settings and turn off everything you do not need running.
Install your favorite media player, web browser etc. to replace the deleted original apps.
Can replace Calendar and Messenger with Google Calendar and Google Messenger to remove some more Xiaomi dependencies. Contacts & Dialer are much harder to replace - True Phone is the only viable option.
To further limit Xiaomi unsolicited communications, rename (or delete) /system/xbin/tunman to tunmanbak. (This is a tunneling protocol driver that Xiaomi uses without your knowledge or permission).
The startup is disabled in the boot.img but it can still be started after boot unless renamed.
To skinny the Themes footprint:
Go to /system/media/theme/
Delete elder-default folder if no use.
Delete entire contents of miui_mod_icons folder
Delete items in /system/media/theme/default/ that are not going to be used.
Delete items in /system/media/lockscreen/ and /system/media/wallpaper/ that are not going to be used.
Now install your favorite app for monitoring CPU parameters and make sure that on idle, there is only one cpu core running and it sits predominantly on 403MHz. It will jump a little bit but that is normal with the inevitable background activities. Increase the timer_rate if you want more stability at idle rather than cranking up the load figures too far. Up to 50000 or down to 30000 is O.K (remember we are talking microseconds here so 50000 = 50mS)
Congratulations! You now you have a "Super Skinny" MIUI installation. Do a backup now!!!!
Now you will feel the AOSP shining through - and still you have working everything!

This post will list useful tools and items that need further investigation.
Apps for finding and disabling things:
Wakelock Detector-Root - monitor and records wakelock activity
GSAM - monitors what apps / services are consuming battery
Disable Service - disable services started on an app by app basis
SD Maid, Titanium Backup - Freeze / remove apps, toggle autostarts (receivers)

Issues:
Find a way to completely disable XMPush service with and without Xiaomi services framework installed.
Xiaomi Services Framework causes Sim connectivity issues if deleted - do not delete. There will always be one XMPush instance running.
Find out what is causing Audio On wakelock reported by GSAM

I have now unchecked that option, and will see over the next day or so whether it resolves the problem. This appears to be the fix
What triggers no sim / no service errors
Removing Xiaomi Services Framework is the culprit
Why do some files / folders not show up in root filemanagers?
MIUI locks the files / folders to prevent them being used or shown.
Why does zram not work anymore?
Rename tiny_mkswap, tiny_swapon, tiny_swapoff to teeny_mkswap, teeny_swapon, teeny_swapoff
Make sure owner is root shell and permissions are 0755 for all 3 files.
edit the init.d script to reflect the change in filenames. Now it will work again!

Example full Skinny ROM based on MR7.2.30 ID:
This is how my phone is set up, it has 100% functionality, zero FCs and zero battery drain on idle. The init.d settings are exactly as provided. Compare the directory listings to your own to see what is deleted.
The other major variation to this is for people who want to keep MIUI Launcher (and MIUI Wallpaper), everything else should remain the same. This cost you a bit more RAM usage and slightly more cpu activity (less battery) but is still impressive compared to stock.

Thanks a bunch for the info. This is exactly what I'm looking for (my slimming down attempts always resulted in bootloops, so I've been playing it pretty safe so far).
Is this something you repeat every time an update is being pushed to your RN2?

@elaurens By doing this you are forgoing the use of OTA Updates which will unravel everything you have achieved.
I had to go through quite a few bootloops before creating the "safe lists" - I suffer so you can all benefit.
If you are starting with 7.1.4 everything is perfect and needs no more updating
Keep your eye out for additions to these lists as I discover or remember them

I have tried this:
http://forum.xda-developers.com/red...d-enable-clearmotion-miui-based-roms-t3278552
to enable ClearMotion and can vouch for it being safe - as in no malware and no breaking things. It adds the following to Build.prop and puts some hacked drivers in /system/lib.
persist.sys.display.clearMotion=1
persist.clearMotion.fblevel.nrm=255
persist.clearMotion.fblevel.bdr=255
ro.mtk_clearmotion_support=1
ro.mtk_slow_motion_support=1
ro.mtk_16x_slowmotion_support=1
Is this a worthwhile thing to do? There are no negatives in doing so as far as I can see but I don't really have anything that can give this a proper workout.
Can anyone see a difference in video playback? (Must have hardware acceleration selected) I won't recommend this if there is no perceivable gain.

most of the stuff works fine, everything checks out, It's not really anything new, but i find it well written, and it's not just a "placebo build.prop tweaks edit" which is a +. its a smart thing to have it all in a single thread.
however there're some issues with init.d script. even if you get init working, sometimes it just simply wont apply any of the tweaks. interestingly enough, i forced it to create a new text file on every boot, and that works. not really sure whats causing this prob.
anyways, by some magic I eventually made it apply the script, not really sure if it was cause of the rom change, or just pure luck lol

@sikica133 and anyone else having init.d problems:
init.d problems are usually one of the following:
1. incorrect folder permissions.
2. incorrect file permissions
3. No line feed at the end of the file (blank line)
4. incomplete or missing Busybox install
5. missing header in the text
6. Loosing SU privileges
Check init.d folder has 0755 permissions
Check file has at least 0644 permissions
Check and/or insert a line feed at the end of the file
Install busybox on rails, run the cleanup and busybox install, uninstall busybox on rails after this (this gives you an up-to-date and more complete busybox installation)
First line of file must be exactly #!/system/bin/sh
Reinstall a fresh version of SuperSu through TWRP
I sometimes get caught out myself by editing a file on the PC and transferring it back without fixing permissions afterwards:silly:
I have the ultimate build.prop tweak that I will share with you all now, stand back, it is very powerful
persist.sys.use_qualcomm_performance_features_instead=1

nah, i was testing it with a updater-script doing 0755 on all scripts. busybox should be fine cause other scripts did their job. dunno, could be some funny issue on my end. works now, i was just wtf, everything works, this doesnt. no idea what was going one tbh, but it works
could be incompatibility with bbox and the script itself? im running it without feedline atm, and it applies it all. same script i used before when it didnt do anything.

MIUI 7.1.4 and I assume all other versions has a very old and incomplete version of busybox installed (I think it was v1.20?).
It does not have fstrim command (plus a few others) included which is why I recommend updating.

I tried init.d and 01_tweaks script (whith correct permissions).
The system is more time in 806 Mhz., deep sleep not works properly.
I use Stable 7.1.1 .
Deleting script, deep sleep works fine.
Need I install or update busybox for resolve my issue?

@Xabadou This script is the starting point. If you do not "skinny down" MIUI, there are so many things running in the background that you will find it difficult to sit on idle frequency.
How far into skinnying down have you gone?
Also, if you have a 2.2GHz cpu, the 2nd line below frequencies in bold must be modified to valid frequency for that cpu.
If you are not going to skinny down to a great extent, then it helps to bump some of the load settings up a touch.
These are the original lines:
echo 80 > /sys/devices/system/cpu/cpufreq/interactive/go_hispeed_load
echo 90 403000:70 806000:81 1183000:84 1326000:87 1469000:90 1625000:93 1781000:96 1950000:99 > /sys/devices/system/cpu/cpufreq/interactive/target_loads
# for 2.2GHz cpu: echo 90 403000:70 806000:81 1183000:84 1326000:87 1482000:90 1664000:93 1885000:96 2158000:99 > /sys/devices/system/cpu/cpufreq/interactive/target_loads
Modify to:
echo 85 > /sys/devices/system/cpu/cpufreq/interactive/go_hispeed_load
echo 95 403000:75 806000:81 1183000:84 1326000:87 1469000:90 1625000:93 1781000:96 1950000:99 > /sys/devices/system/cpu/cpufreq/interactive/target_loads
This is enough to get it to sit on 403MHz idle in most cases. If you go higher, you will start compromising smoothness. There are no problems at all with entering deep sleep.
If you are still having problems, you have an app running that is badly behaved - identify it and deal with it.
Refer back post #10, I mention why you should upgrade busybox.
I am running my phone beyond Super Skinny and loving it. Super stable and battery friendly while still being a performance beast. You should notice even at the point of trimming down to Skinny, this phone really starts to liven up.

Do you have a list of the apks (and directories) that you deleted in order to get the skinny ROM? Such a list would be useful for writing a script to automate the task.
P.S.: you might have noticed that I am a script fanatic - I generally find that it is less error-prone to automate such tasks with a script - and you only need to get the script right once.

I use stable 7.1.1 by xiaomi.eu whith your modded kernel and a lot of apps frozen (App Quarantine).
Modified kernel works very good.
Just now I have updated busybox.
I have 2.0 ghz version.
I will try again the script.
Clear Motion mod works fine in MIUI roms but you must use MX Player for play videos.

persist.sys.use_qualcomm_performance_features_inst ead=1
Works qualcomm tweaks whith mediatek processors?

@DarthJabba9 The lists ares already mentioned - 1 to get to skinny, 1 to get to super skinny but if you do this in a script on a live system you will likely end up in a bootloop because there are too many odex and cache entries orphaned for Android to handle in one hit. If you intend to apply a script to the ROM files before installation, that is a different story. It takes a bit of effort to figure out how and where MIUI is loading a lot of its components from but is doable.
Why I have not offered a complete ready to go package? It is too easy for users to do it themselves and add their preferences along the way. For those that have actually followed through with the process, I can guarantee that they will instantly loose interest in any other custom ROM.
@Xabadou Thanks for the clarification on ClearMotion. I run VLC set to hardware acceleration and can't see the split screen test mode. Video looks fine regardless, so really hard to tell if anything has changed.
Do the apps that you quarantine stay not running? I had problems with quite a few apps running regardless of being frozen or not so had to uninstall.
You, along with everyone else are not running a modified kernel - the kernel remains intact since we do not decompile and recompile or compile it from source.
The "persist.sys.use_qualcomm_performance_features_instead=1" tweak is a sarcastic dig at the many tweak offerings that do absolutely nothing:silly:
You asked the question showing you were not ready to accept this at face value:good:
If there is no evidence of a tweak doing something positive, don't blindly use it!!!

This is a customized boot image that provides init.d support and has unnecessary entries removed. No tweaks are embedded.
It is built on 7.1.4 and can be used on stock 7.1.1 to 7.1.4.

credits to @DarthJabba9 for the alternate init.d support method adopted in this image. It circumvents using busybox run-parts method that appears to have some bugs.
