[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)

Can you post the original post you are following? You might need to create your own goldcard.

[GUIDE][ROOT] Root almost any china android phone

Use any 1 of the following methods.
I have personally tried these on 2 of my china android phones.
1. Using linux {Recommended}Install Ubuntu or DebianEither
Install the android-sdk.
dl.google.com/android/adt/adt-bundle-linux-x86-20130717.zip <==x86
dl.google.com/android/adt/adt-bundle-linux-x86_64-20130717.zip <==x86_64
or
Just get the standalone adb and fastboot executables
texasice-cream-sandwich-mirror.googlecode.com/files/adb_fastboot.zip​Install ia32-libsRun this in a terminal
Code:
sudo apt-get install libc6-i386 lib32stdc++6 lib32gcc1 lib32ncurses5
Now download the files required for root and put it in the same folder as adbmir.cr/GDEPZT4V​After you finish installing the files,
Connect your device with debugging mode enabled
Run
Code:
cd path/to/adb
where "path/to/adb" is the directory of your adb file
Now run
Code:
sudo chmod a+x adb
sudo chmod a+x fastboot
>>Root
Code:
./adb devices
./adb push psneuter /data/local/tmp/
./adb push busybox /data/local/tmp/
./adb push su /data/local/tmp/
./adb push Superuser.apk /data/local/tmp/
./adb shell
Chmod and run the exploit under adb shell
Code:
cd /data/local/tmp/
chmod 755 psneuter
./psneuter
Now re-engage an adb shell to check if the exploit worked.
Code:
./adb kill-server
./adb devices
./adb shell
If you see a # sign, the exploit was was successful. Otherwise repeat from >>Root
Now run these on the same adb shell
Code:
cd /data/local/tmp
./busybox ash
mount -o remount,rw /dev/block/mtdblock0 /system
cp /data/local/tmp/su /system/xbin/su
chmod 6755 /system/xbin/su
chown 0.0 /system/xbin/su
cp /data/local/tmp/Superuser.apk /system/app/Superuser.apk
chmod 777 /system/app/Superuser.apk
cp /data/local/tmp/busybox /system/xbin/busybox
chmod 6755 /system/xbin/busybox
Now reboot your device and open up SuperSU. Let it update the binary.
Your device should be rooted. ​2. Use Windows + MoboroboMethod 1 {Recommended but hard}
Download Moborobo from
Code:
moborobo.com
This software can Install drivers for many china phones and other branded phones.
After installing Moborobo download the files required for root
Code:
mir.cr/GDEPZT4V
Extract the files to the installation directory of Moborobo.
Code:
C:\Program Files (x86)\Moborobo
Run a CMD window under that directory and type
Code:
xcopy AndroidInterface.exe adb.exe
Connect your device in debugging mode & Open up Moborobo, It will install the drivers.
Keep Moborobo open & Follow the instructions mentioned in >>Root
P.S- the linux commands begin with a "./" remove this in windows or else it won't work. Note: Wherever I mentioned a terminal, the windows equivalent to this would be cmd​Method 2 {Easier}
Download and Install Moborobo just like above and run this under a cmd on that folder
Code:
xcopy AndroidInterface.exe adb.exe
Also download UnlockRoot or SuperOneClick
To make sure the adb files are of the same version, Copy over
Code:
adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
to UnlockRoot's tools directory or SOC's ADB directory
Connect your device in debugging mode and open up moborobo.
Now keep Moborobo open and Run UnlockRoot or SOC. ​Good Luck :good:

Hi there!
under method 2 in the end...I could not locate ROOT nowhere.....

I said follow the instructions mentioned in ">>Root".
I named a step in Method one as ">>Root". So I meant you should repeat those steps.

Now download the files required for root and put it in the same folder as adb
mir.cr/GDEPZT4V
Click to expand...
Click to collapse
What files?
EDIT: managed to do all the steps using method 1 in windows but got this message with executing ./psneuter :
mnmap() failed. Invalid argument

I used windows to root
failed at adb shell psneuter command...
/system/bin/sh: psneuter: not found
how to proceed ?

Easiest way to temporarily get root on Android

Hi
I have a new Android device, it's not any of the ones that have their own forum.
More specifically it runs Android 11 on top of a 4.19.193 Rockchip BSP kernel.
I need to read one or two specific files but these files are only readable by root.
I have ADB shell access.
What I do want to acheive:-
Temporarily have an ability to copy a file that's readable only by root, this could be by some GUI app that copies files, as long as the copy is readable by normal user, running commands as root, copy a partition to an image file, export to a desktop machine and read it there. Any one of these would get me that file.
What I don't want to do:-
I don't want to permanently modify the device, unlock the bootloader, put su into /system or anything like that.
Does anyone know of a rooting app that can give me temporary root access but then doesn't actually change the system?
thanks

To get temporary super-user ( AKA root ) rights on an Android's device shell all you have to do is to find a suitable su binary and copy it onto Android's filesystem.
A: To run Android shell commands with super-user right from within the shell on desktop computer ( AKA Command Prompt ) you have to run within desktop computer shell
Code:
adb devices
adb push <LOCATION-OF-SUITABLE-SU-BINARY-ON-PC-HERE> /data/local/tmp/
what will 1. connect the Android device to your desktop computer and 2. upload the su binary in the Android device temporary directory always available for the user.
B: Then, in desktop computer shell type
Code:
adb shell "cd /data/local/tmp & chmod 776 su"
what makes the su binary executable: its ownership by default is set to shell.
C: Then in desktop computer shell type
Code:
adb shell "ls -l"
what will show you content and permissions on recently uploaded files.
D:
To apply a series of Android shell commands what require super-user rights you now would run
Code:
adb shell
export PATH=/data/local/tmp:$PATH"
su -c "<SHELL-CMD-HERE>"
....
su -c "<SHELL-CMD-HERE">
exit
BTW:
When in an Android shell another process like su gets started then this spawned process runs as a child process means it inherits most of the parent process attributes.

adb push allowed me to send the file
Code:
adb push su /data/local/tmp/
su: 1 file pushed. 1.2 MB/s (11640 bytes in 0.009s)
but the adb shell command is failing
Code:
adb shell "cd /data/local/tmp & chmod 776 su"
chmod: su: No such file or directory
if I then log in over adb I don't seem to have permissions to do anything in data
Code:
adb shell
ls -al
drwxrwx--x 47 system system 4096 2022-09-02 16:31 data
cd data
ls -al
ls: .: Permission denied

additionally, I thought that su would need the suid bit set
Does chmod 766 acheive that?

oh this works
Code:
adb shell
cd /data/local/tmp
ls -al
total 18
drwxrwx--x 2 shell shell 3452 2022-09-02 16:32 .
drwxr-x--x 4 root root 3452 2022-07-27 03:04 ..
-rw-rw-rw- 1 shell shell 11640 2022-09-02 16:29 su

Code:
chmod 776 su
ls -al
total 18
drwxrwx--x 2 shell shell 3452 2022-09-02 16:32 .
drwxr-x--x 4 root root 3452 2022-07-27 03:04 ..
-rwxrwxrw- 1 shell shell 11640 2022-09-02 16:29 su

Code:
adb shell
export PATH=$PATH:/data/local/tmp
su
su: setgid failed: Operation not permitted

The device has separate boot_a, boot_b, dtbo_a, dtbo_b partitions.
If I could be reasonably sure that booting a boot partition from a similar device (I have one) would pick up the dtb from this device then I think I could be reasonably confident of not frying anything, I might try and boot it from fastboot.
