How do i enable compcache on CM 3.9.2 and higher? [SOLVED]

I have been searching for a clear guide to enabling compcache on 3.9.2, but there is so much info about swap and compcache in this forum i feel like im running around like a chicken with its head cut off.
so far i have pushed 3 different userinit.sh files into my /system/sd with no change.
#free shows 0 swap , #cat /proc/ramzswap says doesnt exist , #cat /proc/swaps comes up blank.
So i searched more and ended up making a 32mb linuxswap partition on my sd and cant figure out how to get that moving either.
Im bogged down with information and have no idea where to start.
Someone point me in the right direction please. Im a swap/compcache noob...
i would like to run them both together, but as i said i need a noob setup guide

Your /system/sd is a mounted ext filesystem, correct?
Push the userinit.sh from here:
http://forum.xda-developers.com/showthread.php?t=542304
Then run it as root and report back any results:
# /system/sd/userinit.sh

i pushed userinit.sh to /system/sd/ with adb
then put in console
su
# /system/sd/userinit.sh and got /system/sd/userinit.sh: permission denied
should i be doing this in the recovery console?
and what did u mean by: is my system/sd/ a mounted ext filesystem?
i did adb remount to mount /system/ as r/w if thats what you meant.
let me apologize once again. i have almost no knowledge of linux commands. a step by step would really save some time. the only thing i hate more than not understanding something, is wasting others time while i do it.

sounds like you did not set up a second partition (or a 3rd for that matter) on your sdcard.
there are many different ways to do this (I prefer gparted in linux), but here's one guide that uses parted in cyanogen's 1.4 recovery image:
http://forum.xda-developers.com/showthread.php?t=534714
hit me up if you hit a snag

im pretty sure you are right. My mmcblk0p2 exists (of course) but when I check # /dev/block/mmcblk0p3 it says not found. And if I # ls /dev/block/mmcbl0p3 it says no such file or directory.
Im guessing i botched something in paragon partition 9. if i remember correctly i put the 32mb linuxswap partition between my fat32 and ext3.
Do u think i should create a new linuxswap partition after my ext3 with paragon9, or is there a workaround for my mistake? does the phone even recognize my poorly placed partition as anything?
thanks so much for your help. after a few hours of reading all these threads Ive come to realize you are the resident expert in swap compcache scripts. as for myself.... not so much

ext should be 2nd partition.
...and linux swap 3rd if you're using it (but it's not needed for compcache -- only as a backing swap).
I'd kill them both and readd with some variant of parted -- i've read that some are having trouble w/ paragon partitioning

Very well then. Ill reformat today and report back.

First of all! Paragon Partition Manager is a FARCE!
Gparted Live CD was awesome. Paragon had my sdcard looking pretty bad. I had 32mb of unallocated space between my FAT32 and EXT3. Even though paragon was telling me it was formatted to linuxswap.
I moved my ext3 over and created a 32mb linuxswap at the end of the sdcard with no loss of data. wow
But sadly, i pushed the userinit.sh #free shows 0 swap and #cat /proc/swaps shows nothing.
Im going to try this >> http://forum.xda-developers.com/showthread.php?t=542899 <<<WORKED!!

What ive learned:
Use Gparted to create a linuxswap partition AFTER your EXT3. Paragon is pure ****.
Get the user.conf and userinit.sh file from the link in above post.
Put them in the root of your sd card
I DID THIS WITH TERMINAL
su
mount -o remount,rw /dev/block/mtdblock3 /system
cp /sdcard/userinit.sh /system/sd
cp /sdcard/user.conf /system/sd
chmod 755 /system/sd/user.conf
chmod 755 /system/sd/userinit.sh
type #sh /system/sd/userinit.sh into console to activate the script.
type #sh /system/sd/userinit.sh -s to get a pretty well detailed report of the goings on.
OOOh being a linux noob is much headache.
Alpapa Thanks for giving me your time and pointing me in the right directions. Thanks man.

I'm a newb as well... so did you chmod either of those files after moving them to ext2/3?

Yes. You have to chmod both of them.
And this works on 3.9.4.
V 0.1 files work best.
http://forum.xda-developers.com/showthread.php?t=542899
And these files come with everything disabled, so you have to edit both of them and enable what u want before putting them on your sd.
0=disabled
1=enabled

[Solved] Can't flash ROM?

Hi, i try to flash Cyan's new rom v4.0.1, but i keep getting this error message in my recover console:
E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0)
(No such file or directory)
E:Can't mount SDCARD:update.zip
Installation aborted.
After trying unsuccesfully to flash the rom, my sdcard can no longer be seen in my phone and it became write-protected, unable to move files into the sdcard. Appreciate your help....
Edit: Yeah solved this menacing but simple problem which i found out is my sd card fault. Since i couldn't access sdparted in the recovery console, i had to use Ubuntu to partition my sd card again. Sighs... now i have to replace everything back into phone. Thanks anyways for those who gave advice.

is your sdcard formatted to fat32? because /dev/block/mmcblk0p1 or /dev/block/mmcblk0 is referencing your first partition or your sdcard respectively.

you dont flash a rom in consol
you flash it from the recovery screen. you probably CAN flash it from consol, but its much easier to flash from the recovery screen. what recovery image do you have?

yes my sdcard is fat32(1st partition) and my 2nd partition is ext3 whilst the last is a linux-swap partition...

Well I've Always had the best luck with my partitions in order as follows Fat32-Ext3-Linux-Swap(if you use it)
And if you still have problems this is what I do
Well I re-downloaded the update. and did this.
This is how I installed without any problems:
: rename to update.zip
: place in the root of sd card
: shut off device
: boot into recovery
: wipe (alt w)
: go to console (alt x) and hit enter
(enter)
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# cd /system/sd
# rm -rf /system/sd/*
# reboot recovery
: now wipe again (alt w)
: run a filesystem check from the menu. If it tells you to run it manually,
drop to a console (alt+x) and run "e2fsck /dev/block/mmcblk0p2".
: flash
Enjoy!!
Hope this helps!!!

The problem is i can't even mount mount my 2nd partition, and everytime i write the command > # mount -o rw /dev/block/mmcblk0p2 /system/sd < , it justs says no such file or directory found.
I also can't go into parted in the recovery console so the now the problem is i can't even reformat my card. I'm going to try Ubuntu and reformat my card and partition it again. Sighs...

please, can you tell me how did you solved it, did you use ubuntu to reformat the sdcard? thanks in advance..

Yes, since i was not able to access parted in the recovery console, my only choice was to use Ubuntu: Partition Editor. When i diagnose my sdcard, i manage to format only my ext3 partition so my fat32 remain unchanged. You need to go download Ubuntu OS, then try to install or LiveCD the Ubuntu. There is a thread under android development which will guide you on how to do this...

Changing a SDCard

I have a Kingston 8Gig Class 4 and i just bought a Transcend 8Gig Class 6 SDCard.
Can someone please tell me step by step how to backup my class 4 to and restore it to my new Class 6.
Thanks in advance!

ubuntu is the easiest way believe it or not as it is the only o that will see ur partition when u mount ur sd card. check out the wubi installer. or u can use adb.
adb remount
adb pull system/sd/app to pull the apps off, just replace pull with push when u want to put them back on the ext.

i can't recall the exact thread in this Q&A section but there was one that showed how to backup /system/sd to your sdcard then you could pull those files off on a computer and put them on the new sdcard then copy them back over to the second partition.
i think they were something like
Code:
mkdir sdcard/ext2 (the directory name doesn't matter just whatever is easiest for you to remember)
cp /system/sd /sdcard/ext2
someone correct me if something is wrong with those. then put those files on your new sdcard and go to the recovery console so you won't have to worry about any force closes with the new sdcard. make sure you do this after partitioning your new sdcard
Code:
mount /system
mount /sdcard
mkdir /system/sd
cp /sdcard/ext2 /system/sd
i think the commands were something like that. but if you have adb then the way posted above is the easiest for me.

Why don't you just use backup(for root) users application? just copy the folder it creates on your sdcard to your drive, and place into the new sdcard.

@David, I think those commands would work, but here's what I always do (and can verify it works).
Code:
rm -r /system/sd/dalvik-cache/*
rm -r /system/sd/app_s/*
cd sdcard
mkdir ext
cp /system/sd/* /sdcard/ext/
Then to push back
Code:
mount -o rw /dev/block/mmcblk0p2 /system/sd
rm -r /system/sd/*
cp /sdcard/ext/* /system/sd/
reboot
Its best to do all that in the recovery console, or adb shell when the phone is in recovery. Don't do it while the phone has booted in the ROM.

Thanks for all the help/reply...
one more question... how do i do it? do i do it in the terminal? console? or adb?

What they just gave you would be done in terminal.

I said at the bottom of my post. Recovery console is best, if you do it when your phone is actually running you could have issues.

Well yeah, ideally when the phone is in recovery...

i have a Desire and im wondering if there's a easier way to clone the sd card to another bigger. Any idea ? Cloning softwares ?

What about just dd the SD card. something like:
1. Turn off the phone
2. dd sd card to img file
3. dd img to new file
4. New sd in slot and reboot

Switchrom and Wipe ext3

I am using the Switchrom script with CY recovery. I have successfully made backups and switched between roms using the script. Now I want to try the new Drizzy Hero rom. To install the rom I will have to wipe the ext3 partition. My question is, If I wipe the ext3 partition, will I loose the script? If yes, can I copy the script in system/sd later on for it to work again?
PS: Before someone posts "search the thread" answer, I tried doing it and couldn't find anything.
Thanks

The only thing that is stored on your ext3 partition is your apps. So when you clear that only your apps will get cleared.

Thanks man. Wiping now.

To clear this up for other reader who might stumble on this thread, the above comment is not true. If you wipe you ext 2/3 you might end up wiping more stuff than just apps. I realized it the hard way lol. However you can push back switchrom.sh in /system/sd and you will be good to go. The alternate method to do this is to delete just the following folders:
mount /dev/block/mmcblk0p2 /system/sd
rm -rf /system/sd/app*
rm -rf /system/sd/dalv*

You can do that or you can wipe buy doing this
Code:
mount /system/sd
mount /sdcard
rm -rf /system/sd/*
cp /sdcard/switchrom.sh /system/sd/switchrom.sh
That's how i've been doing it. And I like to do it this way to make sure the my EXT2/3 is completely clean. I've had problems where doing a partial wipe gives me issues. But yes if you wipe your EXT2/3 drive it will get rid of everything (including the switchrom.sh)

when you wipe your internal phone memory and ext3 you will lose the script. once you get the rom you flashed up and running again, just repush switchrom.sh and you are good to go again. wiping the ext 3 or the internal memory WILL NOT wipe out your backups. when i use switchrom i dont even wipe all of ext3...
this is what i do... flash a new rom. get it setup the way i want. install all apps and extra settings i want. reboot into recovery, run switchrom.sh and let it do its thing. now when you have created your back up and want to flash a NEW ROM, not one of your backups, wipe internal memory of course but instead of wiping all of ext 3 drop down to recovery console and do the following
Code:
# mount /system/sd
# rm -rf /system/sd/app*
# rm -rf /system/sd/dalv*
this will prepare your ext3 for a new install of a new rom. when you are going back and forth between your backups you do not need to wipe ext3 at all. the script takes care of all of that. if you have any more questions PM me or hit me up on gtalk - palosjr
NOTE- this script is case sensitive as i found out the hard way... when bookmarking and tagging ROMs be sure to use all lowercase. if you use uppercase the script will fail. hope this helps bro.

thanks guys, i got it to work.

Switching SD Cards

I just received my new class 6 SD card in the mail today, and I was wondering how I can transfer all my files over to it. I don't mean like music and stuff like that, but like my Apps2SD. I don't exactly know what all I have to transfer over, but if someone can give me the adb commands and what I'm trying to transfer, that would be great.

Go to the recovery console
mount /sdcard
mkdir /sdcard/ext
cp /system/sd/* /sdcard/ext/
the copy the ext folder to your new card, put it in your phone and go back to recovery
mount -o rw /dev/block/mmcblk0p2 /system/sd
cp /sdcard/ext/* /system/sd/
I've probably made a couple of mistakes with mounting the partitions correctly, so you may have to mount /sdcard on the second batch of commands.

Use Adrian's method

awesome, i've been wanting to know how to do this myself so this will definitely come in useful.

B-man007 said:
pretty sure the adb command is
adb pull /system/sd/*
then use adb push to get it back on the new one.
that should get everything on your ext partition. (note: do this while phone is booted into the rom. else you will need to mount the ext partition)
(if you need clarification, dont mind asking)

What? Pushing apps to the ext is not a good idea when the phone is in the ROM (when I tried half of them showed and half of those FCed)
You can easily mount your ext - mount -o rw /dev/block/mmcblk0p2 /system/sd

i don't push i use adb install that way all of them get installed and i don't have the problem with certain apps not showing up right.
you say that like i want to type a really long command, i just use adb remount, or if i am forced to use my phones keyboard for command i just go to the recovery console and use mount system or mount system/sd depending on how specific i feel . (i hate typing commands on the g1s keyboard, and its and epic fail if you mess a long one up.)

easiest way i have done this is do a switchrom backup, make sure its saved to your old sd, get your new sd partitioned correctly, and copy the switchrom folder from your old sd to your new one, then do the normal steps to restore a switchrom backup... this will restore your rom to the exact moment it was when you saved it. had me back up and running in 10 minutes after a new sd was here.

Thanks so much for the help guys, I just noticed that I left my USB cord at work :/, so tomorrow I'll get back to you guys about this.

ya i started my response and saw you already answered so i was like mehhhh
i wrote my own script to do all this stuff below for me, and its done through the recovery.
Back up apps
Remove app_s folder
Reformat ext3 partition
Restore apps
Enter Recovery
SwitchRom Backup/Restore
Clear Dalvik-Cache
adb push while booted works fine for me, it just slows the crap outta the phone for a good 2-3 minutes, but it works fine. i use push because adb install hasnt always worked 100% for me (i have ~130 apps, and some of them don't install.)
anyways ill edit out my post to stop confusion

i have no more then 40 apps so adb install doesn't really flunk out on me
the only thing i don't like is the protected apps that show up in the fugly system default app icon and the long name.
