Lag Fix for Galaxy S "Showcase"

I'm sorry to post this in the Fascinate forum, but as you all know Cellular South's version the "Showcase" is identical in hardware as is the Mesmerize, but there isn't a forum for either of them..
I see there's plenty of kernels and etc.. But is there just a simple lag fix that I can do to my Showcase that will make every day use better and less laggy?
A simple yes or no is fine with me.
if there is a way a link post or explanation would be VERY appreciated.
Thanks,
Elijahblake
(PS)Sort of on the same subject, but I read that gingerbread is going to support ext4 file system. I know the Galaxy S uses the RFS file system which I believe is where we get the lag in the first place.. Will it be possible to switch file system formats?
I'm not real familiar with all these Linux formats. Would it be similar to reformatting like from FAT32 to NTFS?

If you can provide some additional information and files, I can port some things such as Voodoo lagfix to your device.
Needed:
stock kernel
stock mbr
mount output
All of the following can be done through adb on a rooted device.
To dump the kernel do:
cat /dev/block/bml7 > /sdcard/zImage
To dump original mbr do:
dd if=/dev/block/mmcblk0 of=/sdcard/showcase.mbr bs=512 count=1
To get mount output do:
mount
then paste the output of that command as well as upload the showcase.mbr and zImage files here.

look for the thread in the fascinate forum simply titled "root"
also you will need to locate the thread explaining how to get clockworkmod recovery on the showcase in the same forum

will do.. May take me some while to get all this info gathered..
quick question? I've read of some people not being able to see certain apps in the market after rooting.. Is this still the case?
If my phone is rooted and 2.2 finally does come out (officially) will have to un root and remove any lag fix to upgrade? How hard will this be?

To get the upgrade, you shouldn't have to un-root, but you should probably disable voodoo first as the update will almost certainly have a new kernel, and applying the update without disabling voodoo could cause quite a headache.
If you do apply the update right away, you could quite possibly loose root, so you may want to wait until the devs re-root the update. This could make things easier for you as the rooted update will also likely be cleaned up some.
To disable voodoo, you'd just need to create a file called "disable_lagfix" in /sdcard/voodoo and then reboot your phone. See the thread in the dev forum about removing voodoo for more details if you want.

ok well it looks like I'm rooted.. Now I tried to open the ADB that came in the fascinate root zip but it's not opening for more than a split second... you have a download link?
Also can uninstall all this bloatware now??
edit.. thought I had Android SDK on this laptop.. Downloading it now

I have c:\androidsdk
I put ADB inside tools and it sees my device when I run ADB devices
But on the commands you listed nothing happens, I'm not sure if that's the entire commands or if I'm supposed to add something to them..

Try to run the following
Code:
adb shell cat /dev/block/bml7 > /sdcard/zImage
adb shell dd if=/dev/block/mmcblk0 of=/sdcard/showcase.mbr bs=512 count=1
adb shell mount
or just typing "adb shell" and entering the commands at the new prompt, and typing "exit" to get back to the normal command prompt.

here's what happened..
the first two commands didn't work. DO i need to create a folder name zImages?
The second command said access denied..
You tell me if the mount worked haha..

jt will have to comment on whether that is what he needs from the mount command. Can you try the following to see if it works?
Code:
adb shell
su
shell cat /dev/block/bml7 > /sdcard/zImage
shell dd if=/dev/block/mmcblk0 of=/sdcard/showcase.mbr bs=512 count=1
exit

well, it granted me SU rights.. but still a no go...

i figured since i was in shell i shouldn't type that.. still got no directory found...

would root explorer make this any easier?

I just tested out all of the commands on my Fascinate and they all worked, so I'm guessing that the Showcase is putting stuff in a different place. jt will have to help you out further as I'm not sure of where else to look for the info he needs.

for the cat command it should bml as in lowercase L, not 1. And it looks like you added a space between the of and = on the dd command.

jailbreak ps3 using psfreedom, anyone successfully?

Hi expert,
Has anyone successfully JB PS3 using the following link?
http://psfreedom.com/wiki/HTC_Droid_Eris
I cannot get it to work, just curious if anyone successfully done it would like to share how you accomplish this. There are 2 steps that I have question on, they are:
Fastboot should say < waiting for device >, I don't get this message, I only received boot image loaded OK
insmod /sdcard/psfreedom.ko returns error message "cannot insert psfreedom.ko file exists"
I've been reading the last 3 days and still unable to get this loaded, is there a more up to date instruction for eris? TIA.

psfreedom.ko
Did you copy psfreedom.ko file to your sdcard

wonder if having clockwork or RA recovery makes a difference...

Yes, I have the psfreedom.ko on my root of sd card and I think I do have fastboot on because the command fastboot devices return my phone id.

For what it's worth, very soon you won't be needing any device to jailbreak the PS3, the master key was discovered and most if not all future developments will be signed code making the jailbreak method obsolete.
There's already a working 3.55 custom firmware, though many homebrews still need to update to use it.

Its a recovery img just like Clockwork and Amon_Ra's. Its actually based off of Clockwork. So just flash it to your recovery.

No, I ran it on XP but I can see the PS3 jailbreak option now, there are 3 JB option right? PL3, PSFreedom, or Hermes, so I can just select any to boot my ps3 in JB mode, do you know if these payloads has spoof on them?

I don't believe any of them do. But you can download the other PL3 payloads from the same site also. Then just extract them to you sdcard.

Hi Chev, thanks for all your help, I think I got enough information to go home and mess around with my ps3, I hope it'll work.

anywhere we can read up on this?

FYI, I was able to run the JB last night and it works great, test out some games and got GT5 working so far but it does take a long time to load my GT5 to the HD. I am happy now that I don't have to switch games out for my kids any more .

NS 4G - Need radio image dump

Looking for anyone with a new NS4G to dump a copy of the radio. I messed up and flashed a rom that had a gsm radio attached. rendering my phone useless as far as phones go.

root
post a good root method and how to do the dump. I can have it hotlinked in 1 hour

i used http://jaxov.com/2011/02/how-to-root-android-2-3-3-gingerbread-on-nexus-s/
worked just fine.

Once you're rooted, do
Code:
adb shell dd if=/dev/mtd/mtd5 of=/sdcard/ns-cdma-radio.img count=12583040
Then upload that ns-cdma-radio.img somewhere ;D

?
ok thanks, i will link it when finished
the dumped file will be in my phone memory, correct?

You don't need the platform api, just the SDK tools/platform-tools , that'll save you a lot of download time.

instal drivers?
look to the 2nd rooting method i posted. the 2nd file you download are the drivers. you would install it when your phone is in fastboot mode then go to device manager and upgrade the driver

unzip the rar file and make sure to select x86 or x64 driver for your pc.
you should be able to type "fastboot devices" hit enter and it will return your phone if you have the drivers installed

Also the simplest method to get the drivers might be to put phone into fastboot mode, plug USB to computer, then install PDA Net (which automatically installs the phone drivers). I personally could not get the drivers to install manually on Windows 7, had to use the PDA Net method.

CMD is giving my a Permission Denied with this command

Try this: (I am assuming you've already finished rooting and installed superuser)
run adb shell
that should give you a "$" prompt in your command window (you've just shelled into your phone)
then type "su" (without the quotes)
On your phone, a superuser request should pop up on the screen, hit Allow
Your command prompt should change to a #
then type
dd if=/dev/mtd/mtd5 of=/sdcard/ns-cdma-radio.img count=12583040
*EDIT: made a typo in the original writeup of this post and left out the count parameter*
(no adb shell required before the dd command this time since you're already shelled into the phone)

here it is
http://www.megaupload.com/?d=H3Z7RQLZ radio image for you
Also, from the first root method I cant find this file and move forward
4. Tap on the gray box that says Mount R/W
5. Tap and hold on the file install-recovery.sh and rename this file to install-recovery.sh.old
6. Once renamed, download and install the app called ROM Manager from Android Market
7. Once installed, open ROM Manager app and choose Flash ClockworkMod Recovery option.

i didn't do that i just ran ROM manager and flashed the latest Clockwork. you're backing up the old recovery. in that step, good idea, sure. needed, not really.

Actually the point of renaming that script is to prevent clockwork from being overwritten by the stock recovery.
The default stock rom is set up to re-flash the stock recovery from cache on bootup if it detects that it's been changed (which is very annoying if you *want* clockwork recovery).

thank you very much for uploading that for me
now correct me if i'm wrong netarchy but i would use fastboot to flash the img file?
I just want to double check before i mess up once again. i'm pretty smart and a quick learner but not a pro like yourself

worked?

Help: Is there an Windows app that can backup the Streak ROM as an image file?

Hi,
Is there an app that you can run from a Windows XP laptop that can backup a Dell Streak ROM Image as a single file to a hard drive?
My apologies if this has been asked before, but I seem to only find backup apps that run on the device itself.
Thanks.
PS: Assuming if this is not possible, what is the best way to backup to a laptop hard drive?

Thanks for you reply. That's the step I wanted to avoid by installing a custom recovery.
So I suppose there is no other easier way if I just have a stock Streak with the stock Dell recovery?

Nothing at all. There are non root apps that will allow you to backup your user apps and their settings but anything related to the system will have to be manually reconfigured because your not rooted more than likely either. And those don't work well either.

He could do a system dump using ADB, but to do so he would...
...have to be rooted.
...have busybox installed.
...have to determine where the system partitions are (e.g. /dev/mnt/nanda for /system).
From there he could then execute the commands in a command prompt. For example, to do a system dump on my el cheapo Coby tablet, I use the following commands:
Code:
adb.exe wait-for-device
adb.exe shell mkdir /sdcard/dump
adb.exe shell su -c "cat /dev/block/nanda > /sdcard/dump/bootloader.img"
adb.exe shell su -c "cat /dev/block/nandc > /sdcard/dump/boot.img"
adb.exe shell su -c "cat /dev/block/nandg > /sdcard/dump/recovery.img"
adb.exe shell su -c "busybox tar -czvf /sdcard/dump/system.tgz /system"
mkdir dump
adb.exe pull /sdcard/dump dump
Putting it all together into a single file though is not going to happen. Besides, installing ClockworkMod or StreakMod and doing a nandroid backup through it is the best means of backing up the Streak.

Please help a beginner understand ADB

I am quite proud to have got as far as I have (please see screenshot).
However, I am trying to adb pull my nandroid backup from TWRP onto my PC. I've searched all over the place for the right commands but whatever I type, I get a "could not find" message.
Could someone please let me know what to type to adb pull the nandroid backup onto my PC please?
Also, when I have reformatted my Nexus 7, what do I need to do to adb push the nandroid backup back onto my sdcard?
Many thanks in advance!

It should be in your /data/media/0/TWRP/BACKUPS/015d4172c98600219/ directory to c:/users/a/desktop.

Thanks! I have been at it all day! I've finally managed to adb pull my nandroid backup and my TBU. I now want to sideload them to make sure I can do everything before I reformat my N7. When I enter: adb sideload 015d172c98600219, I get a "cannot read message". What is it that I should be entering?

You can not sideload a nandroid backup. You need to push it to your TWRP directory.

Thanks very much for this. I guess adb is not for me.
This is where I am (screenshots). No matter what code I try nothing happens. I just see a set of instruction run quickly on the screen and then I'm back to square one.
Do I need to do something about the device itself, in "mount" perhaps?
Sorry to be a pain! Don't worry if you don't have the time!

Make a temporary backup so it will create the directory. You should still have your system image after the format so have you tried booting up then copying through My Computer?

Well I haven't reformatted yet because I wanted to make sure I mastered the adb method before I wiped everything. But now I don't know whether I should format at all. Sounds a bit risky if I don't have a rom to go back to!
Sent from my Nexus 7 using xda premium

It's strange, though, that I can successfully adb pull files but not adb push them back. Does anybody have a clue?

Your ROM will still be there after formatting. If is not, just reflash it with fastboot or sideload.
Also, you can't have spaces in the command.
