[Q] downgrading android software. stuck on command prompt

hiya everyone, im new on here and really need some help.
im trying to downgrade my android software so im able to root it. only problem being ive never used command prompt lol!!
the guide im using says:
Launch a Command Prompt window and browse to the location of the files extracted in Step 1.
Enter the following commands:
adb push psneuter /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/psneuter
adb shell chmod 777 /data/local/tmp/misc_version
adb shell /data/local/tmp/psneuter
adb shell
You should now get the # prompt, indicating temporary root.
Enter these commands:
cd /data/local/tmp
./misc_version -s 1.31.405.6
but how do i browse for the files if ive stored them in my documents and in a folder called downgrade android.
many thanks

What device are you trying to downgrade and what version of Android are you currently on? If it's Gingerbread there is a oneclick root called gingerbreak that works for a lot of people.
More info needed really.

help!!

keeps saying not a batch file :s

Moving them into the SDK tools folder temporarily would make things easier and would mean only the file name needs to be typed rather than the specific location, try it out, I hope I remembered correctly

you can either modify the command like this:
adb push C:\users\[YOURUSERNAME]\My documents\downgrade\psneuter /data/local/tmp
or setup a locale path variable to the dir, where adb is stored as mentioned in THIS thread. (step 4)
Then you can simply cd to the dir, where your files are stored, and run adb from there (actually you can run adb from any dir then)

[Q]Installing busybox

Hi,
I'm trying to install busybox into a development board by downloading the pre-compiled binary and following the installation steps here. However, after doing so, I'm still unable to use the commands in /system/busybox. For example, when I try to run mknod, it shows me the following error:
Code:
./sh: mknod: not found
Basically, I did the following:
In Linux
Code:
adb root
adb remount
adb push busybox /system/busybox
adb shell
In device adb shell
Code:
cd /system/busybox
./busybox --install .
./sh
cd /system/bin
mv sh sh.android
ln -s /system/busybox/sh sh
It would seem like what I did to install busybox didn't work. May I know what's the correct procedure to install it?
I tried creating symlinks using the same ln command and it works, but do I have to do this manually for every single command?
Thanks!

Hi,
Where would I add it? init.rc or something?

Anyone?

Ways to root .29?

I've got some questions about rooting on a locked device, which I may as well fire away.
I'm on .17 DE and has got it setup nicely, so I don't want to go to .29 just to try things out, and if something goes wrong it's better if the tablet has got a boot manager installed so rescue flash is possible. So, if someone who knows what they're doing wants to unroot and try this out (or just tell me if anything is feasible) I believe many people (primarily not rooted .WW-people, but maybe all current ICS-device owners) would be very happy.
Q1 - In the "tweaks" post seanzscreams mentions there may be a way to push build.prop to /system/ at boot.
Wouldn't it be possible to create some root stuff to push and run, like
(pushsu.bat)
Code:
adb wait-for-device
adb push su /system/
run it, reboot tablet
create a shell script file for permissions (or some other mojo) and push it aswell:
(permsu.sh)
Code:
chown 0.0 /system/su
chmod 06755 /system/su
and then run:
(pushper.bat)
Code:
adb wait-for-device
adb push permsu.sh /system/
and finally run and reboot:
(setperms.bat)
Code:
adb wait-for-device
adb shell sh /system/permsu.sh
?
Q2 - wolf849 is doing some funky stuff to downgrade firmware where he's mounting stuff at /data/local/tmp and rebooting for (I assume) permissions to write to the "stuff".
Would it be possible to test these commands (modified to possibly work or break something) (mmcblk0p1 = /system on my device):
(in adb shell or something)
Code:
mv /data/local/tmp /data/local/tmp.bak
ln -s /dev/block/mmcblk0p1 /data/local/tmp
exit
Then reboot and see if /data/local/tmp is in fact /system mounted rw (ie "copy or push su"-able).
If the former wouldn't work because of symlinking rights maybe another approach would be a bat file, like
Code:
adb mv /data/local/tmp /data/local/tmp.bak
adb reboot
adb wait-for-device
adb ln -s /dev/block/mmcblk0p1 /data/local/tmp
adb reboot
Please don't try these suggestions if you don't know how to recover from possible bootloops or semibricks.
I would try them if I'd been unlocked and boot managered, but I'm out of luck if something goes wrong.

[ROOT] LG Intuition & LG Spectrum ICS

Source: http://www.androidpolice.com/2012/0...root-the-lg-intuition-and-lg-spectrum-on-ics/
If you find this useful please follow me (jcase) on twitter ( https://twitter.com/teamandirc/ ).
Here you go, root for both the new LG Intuition and the LG Spectrum running ICS. The vulnerability is a simple permission bug allowing us to setup a symlink to local.prop (yes yet again). While the bug is the same, the procedure is slightly different, so I will have the instructions separate.
With the LG Intuition, they did seem to attempt to mitigate this attack. Not by setting correct permissions, but by dropping adbD to the shell user if it runs as root, even if ro.kernel.qemu=1 is set. They failed, they give us enough time to run one command before dropping the root privileges, in our case a script to root the phone.
LG Spectrum ICS Root (for the leaked ICS rom):
Expect this to be patched in the release rom. Leaked ICS rom has locked bootlaoders, ie no recovery at this point.
Files needed:
su ( http://dl.dropbox.com/u/8699733/lgroot/su )
adb shell
$ rm /data/vpnch/vpnc_starter_lock
$ ln -s /data/local.prop /data/vpnch/vpnc_starter_lock
$ exit
adb reboot
adb wait-for-device shell
$ echo 'ro.kernel.qemu=1' > /data/local.prop
$ exit
adb reboot
adb wait-for-device remount
adb push su /system/xbin/su
adb shell
# chown 0.0 /system/xbin/su
# chmod 06755 /system/xbin/su
# rm /data/local.prop
# rm /data/vpnch/vpnc_starter_lock
# reboot
Once rebooted, install Superuser from the market and enjoy.
LG Intuition Root
Files needed:
su ( http://dl.dropbox.com/u/8699733/lgroot/su )
lgroot.sh ( http://dl.dropbox.com/u/8699733/lgroot/lgroot.sh )
adb push su /data/local/tmp/su
adb push lgroot.sh /data/local/tmp/lgroot.sh
adb shell
$ chmod 777 /data/local/tmp/lgroot.sh
$ rm /data/vpnch/vpnc_starter_lock
$ ln -s /data/local.prop /data/vpnch/vpnc_starter_lock
$ exit
adb reboot
You may have to unplug/replug your phone to get some computers to pick it up again after this reboot.
adb wait-for-device shell
$ echo 'ro.kernel.qemu=1' > /data/local.prop
$ exit
Here is the important part, you will have to execute the next to commands one after the other. We want the second command to be fired off as soon as adbD comes up, before it drops root privileges. This may take some a few minutes, and after the second command is complete you may have to unplug/replug you phone to get your computer to see it again.
adb reboot
adb wait-for-device /data/local/tmp/lgroot.sh
(Here is where you may have to unplug/replug, but only after the second command has ran).
adb wait-for-device shell
$ su
# rm /data/local.prop
# rm /data/vpnch/vpnc_starter_lock
# reboot
Once rebooted, install Superuser from the market and enjoy.

Thanks!
Dude, it has been killing me not having root since I managed to get the leaked ICS installed. But I tried this, and just wasn't having any luck. I tried to make a .bat file for it, no go. So i tried inputting it line by line and i keep getting hung up at the $ echo 'ro.kernel.qemu=1' part. Just wondering if anyone else is having this problem.
Also, since yesterday whenever I check for a software update, I'm getting an "error occurred during download". I was wondering if I would even be able to get the final ICS OTA when it finally is available.
Thanks again jcase!

Which specific ICS version do you have, I had a couple different leaks to work with.

Ive got the spectrum, btw. Still trying to make a nice, clean, automated .bat, but it keeps failing now at the remount command.
---------- Post added at 07:37 PM ---------- Previous post was at 07:24 PM ----------
And now is saying "rm failed for /data/vpnch..."
When the remount fails, I get a "remount failed: operation not permitted" message.
Hope this is useful to you.

unplug/replug, The intuition is very touchy. Might need to do it from another system or with another cable.

Place the two commands into a batch file/shell script, or setup teamviewer and msg me on gtalk

so this is just I've come up with tonight, the exploit still fails line by line, so I made a batch file just for that command, and I think I may be misunderstanding that "adb mount - o" command you recomended.

Try now, something was altering my post

Correction needed for Intuition
First of all, thank you!!!
For Intuition, where the 'important part' is, the second command returns an error.
I was able to succeed by running
adb reboot
adb wait-for-device shell
then wait for the # to appear, and quickly paste and execute:
/data/local/tmp/lgroot.sh
took a few tries, but I am rooted! :laugh:

Just wondering how you guys like this device? I was just debating on switching to verizon and this device stands out as the most interesting to me... so I had to look here to see if anybody rooted it.
Anybody try any different roms? or think there may be a Jelly Bean update for it?

/system/bin/sh su not found
any help with this was having an issue with the echo command but got past that but now it's giving me this error

It's an amazing device I love it and im rooted. used the steps above and it worked. I am sure it will get jelly bean love eventually. No roms yet. But LG added a lot of customization to the device form what developers usually add as mods.

Will there be a single click method for root on the intuition. I can't seem to get this method to work

Exploit still works on the final version of ICS for the LG Spectrum
Just updated my phone. Couldn't wait for the OTA rollout, updated via the Verizon Wireless Update Util on my comp. Root worked no problem. Thanks again Jcase!

What did you update your phone to?
