StreakDroid Performance Mod 1

[Guest Stephen Hyde]

ok folks heres a quick update for the more adventurous of you.

first up what is it:

I've re-enabled 1.22ghz & 1.267ghz cpu speeds and they seem stable (please see the note below)

Added ability to use init.d scripts

Added Data2EXT support

Added Files to hopefully preroot the rom

Fix courtesy of mistadman for the this file is not an audio file error

PLEASE NOTE, THE 1.22 AND 1.267 CLOCK SPEEDS ARE HEAVILY OVERVOLTED(~200MV AND 250MV OVER STOCK RESPECTIVELY ABOVE THE STOCK VOLTAGE, THEY COULD VERY WELL FRY YOUR DEVICE IF USED FOR PROLONGED PERIODS, I ADVISE USING A MAX OF 1.19 ONLY PUSH HIGHER FOR SHORT PERIODS

Requirements BEFORE installing

1. A linux ext4 formatted partition on your microsd not bigger than 2gb in size- howto below for formatting

2. memory card reader - you cannot repartition over usb connection on streak

ext4 howto

You need a linux based pc/laptop with ext4 support to do this (must at least have the file mkfs.ext4 available)

1. Connect your microsd to pc and check to find out what device node it has been assigned. (i will be using /dev/sdb for this tutorial)

2. backup any data from card you want to keep before proceeding as all data will be wiped.

3. run the following commands to partition card. im assuming you have a 16gb card, if not you will need to adjust the size enterd to ensure you leave ~1.9gb free for the ext partition

a blank line means just hit enter

fdisk /dev/sdb

o

n

p

1


+14G

n

p

2



t

1

c

w[/code]


this will repartition your card as needed for data2ext



now we need to format it.

[code]mkfs.ext4 -F -L userdata /dev/sdb2

tune2fs -o journal_data_writeback /dev/sdb2

tune2fs -O ^has_journal /dev/sdb2

mkdosfs /dev/sdb1

thats now done and you can copy the update to sd and update as normal now.

FIRST BOOTUP WILL TAKE A WHILE DUE TO THE INIT FOR DATA2EXT wait at least 10 mins before puling battery and starting back up - device should boot fine then

download: http://downloads.streakdroid.com/djsteve/perfmod3.zip

edit: you should also be able to do the partition and formatting via adb shell on device if you push over the mkfs.ext4 file from the zip and chmod it 755

Please feel free to donate to my work if you find it useful :) - any amount is appreciated

What are the advantages of doing this in plain english for the noobs (me)?

Speed boost on core file input output operations..

[Guest LorD CLockaN]

After the partition and first boot up, can I copy back the data that I backed up before??

Ir do I need to do a factory reset!!

Replay fast!! :)

I OC via SetCpu.. it automatically rises the voltage or what!?!?!

I'm booting my linux mint 10 eeepc as I type :)

edit:

DO I have to copy back the data and that aply perf.zip update via clockwork??

Edited December 12, 2010 by LorD CLockaN

[Guest Stephen Hyde]

yes you can throw back the bcked up datea to sd, and yes the voltages are set in kernel their just insanely high

[Guest LorD CLockaN]

So voltages are set automatically

great!! I was hoping for some soldering and voltmodding :)

[Guest Stephen Hyde]

yea voltage is tied to clock speed

[Guest LorD CLockaN]

Last question..

first partition is ext, second partition is?? I copy back data to sdcard's second partition??

Thanx a million!!

edit:

backup complete, now partitioning...

Edited December 12, 2010 by LorD CLockaN

[Guest Stephen Hyde]

first is fat32 second ext

[Guest LorD CLockaN]

Partitioning done, now waiting for backed up data to copy back to the mc.. than update..

So no need to use new recovary?? as you mentioned it in the first post??

edit:

Maybe I should have bought faster MC reader :)

Don't have MC adapter to SD for original card reader :)

[Guest Stephen Hyde]

all you need to do is flash the zip in whatever recovery you use as you would a rom

[Guest fards]

What was mistadamans fix for the audio file error?

[Guest Stephen Hyde]

permissions in init fixes part and stagefright fix for http needs a file replaced also :) both in this update

[Guest superutp]

crap...dont have a linux based pc/laptop..:)

[Guest Stephen Hyde]

can do it on device over adb but its more challenging

[Guest LorD CLockaN]

I did everything as said

applied perf.zip. it booted in 2 min.. Chose 1267MHz, and quadrant only 1600!!

anything else

[Guest Stephen Hyde]

load up adb and run mount, check mmcblk1p2 is mounted

[Guest LorD CLockaN]

I run it in terminal

Only these devices:

/dev/block/mtdblock6 /system yaffs2

/dev/block/mtdblock7 /firstbot yaffs2

/dev/block/innersd0p5 /cache ext3

/dev/block/innersd0p6 /cache ext3

There are lots of other lines of text, but I think these are important

there's no word of mmcblk1p2

[Guest Stephen Hyde]

the data2ext hasnt kicked in, check /system/etc/init.d run ls -l in that folder

[Guest Wee Thomas]

crap...dont have a linux based pc/laptop..:)

Really? Cuz all you need is to download unetbootin and load a live cd onto a flash drive (or an actual cd) and boot linux.

I have a backtrack4 live cd image for use to take care of various tasks that are hard to do otherwise on my win7 laptop.

[Guest LorD CLockaN]

I checked init.d is in there.. folder has all permissions, but insite init.d folder there is a read only file..

there's a folder init.d, not a file

inside init.d folder is a 01dat2ext read only file r--r-----

[Guest jayjayn1]

Ive created a dual boot windows 7/Ubuntu laptop. Will this get the job done?

[Guest LorD CLockaN]

yes

[Guest Stephen Hyde]

lord clockan try

busybox chmod -R 755 /system/etc/init.d

then reboot

[Guest jayjayn1]

yes

cool. onto the next phase.
