Required files:
http://dl.dropbox.com/u/8699733/chainsdd-su.zip

Unzip chaindsdd-su.zip and then get a shell with adb

Code:
adb shell

Set up the dirs, so shell owns them prior to logging. If shell does not own them then we can not control them. If the logs dir already exists, you may have to do a factory reset to remove them. They should not exist unless someone attempted this previously.

Code:
mkdir /data/local/logs
mkdir /data/local/logs/kernel

Open emode's logset activity. First button should be for enabling log set, enable it. Do not exit the activity, but if you do just repeat the below command.

Code:
am start -a android.intent.action.MAIN -n com.zte.emode/.logset

Confirm the log_kernel.txt file exists, if it does not wait a minute and check again.

Code:
ls -l /data/local/logs/kernel/log_kernel.txt

If it exists, delete it and immediately symlink it to /data/local.prop, logset may recreate it, if it does delete and try symlinking again.

Code:
rm /data/local/logs/kernel/log_kernel.txt
ln -s /data/local.prop /data/local/logs/kernel/log_kernel.txt

Now we want to wait for /data/local.prop to be created, it may take a minute or two. Keep checking until it exists.

Code:
ls -l /data/local.prop

Now once /data/local.prop exists, go back to the logset activity and disable logset. If you don't disable it, it will slowly eat away at all the disk space, and possibly overwrite the local.prop before you get root. Now lets set qemu=1 then reboot.

Code:
echo 'ro.kernel.qemu=1' > /data/local.prop
exit
adb reboot

Once you have rebooted, remount, install su.

Code:
adb remount
adb push su /system/xbin/su
adb shell chown 0.0 /system/xbin/su
adb shell chmod 06755 /system/xbin/su

Clean up your mess!

Code:
adb shell rm /data/local.prop
adb shell rm -r /data/local/logs

Reboot, install the Superuser app from the market and enjoy

Code:
adb reboot

Might Not Work As Expected

I just tried this procedure from JCase at the RootzWiki dot com site with mixed results. The phone is a ZTE Merit Z990G from Straight Talk.

I went through all the steps and everything performed as expected. When I start start an app that requires superuser permissions, the app reports that the device has not been properly rooted. I have repeated the process as outlined four times, including downloading the SU file, and have the same results. Titanium Plus, Busy Box Pro and Root Check Basic report that the device is not rooted.

However, a couple of the Google apps - music, movies and reader seem to think the phone is rooted. Any ideas or suggestions will be very appreciated.

Sounds like band permissions on su, try

adb shell ls -l /system/xbin/su

if the permissions come out as "-rwsr-sr-x" then you are rooted, try updating su with the suepruser app, or finding a different copy of su.

If the permissions are different or it says it doesnt exist, then you need to repeat the instructions as you missed one or two

Thank you for the fast response. Here are the permissions for the SU file and based on what you are saying they look good:

C:\SDK>adb shell ls -l /system/xbin/su
-rwsr-sr-x root root 22364 2012-06-17 12:47 su

I have located and downloaded a couple of "su" files from XDA and similar sites and the files are identical. I will continue searching for a different "su" file and see if that makes a difference.

I looked around and did not find any "su" files that were different than what I downloaded according to the root process. Just for grins I copied the "su" file from my Noot Tablet which is rooted and tried that file. Sadly, it did not make a difference.

Please let me know if there is any other information I can provide or if you would like me to try something else.

What happens when you open the Superuser app (note this is not supersu) and go to settings/options and attempt to update su?

It Worked - But Don't Know Why...

What happens when you open the Superuser app (note this is not supersu) and go to settings/options and attempt to update su?

I re-installed Superuser and Superuser Elite and now the phone says it's rooted. I've been in IT for over 35 years and it makes me nervous when software "magically" fixes itself. But now that it's working I won't question it and proceed from here. I appreciate your help and your effort.

Cheers

Generally you have to run superuser once to get it to work I've found, at least recent builds (or maybe its recent android builds)

root or no root

followed steps, ended up with this...

$ ls -l /system/xbin/su
ls -l /system/xbin/su
-rw-rw-rw- root root 22364 2012-07-15 09:25 su

the superuser app shows all blank under apps and logs, when i try to update it, it says "checking" for a few secs and then nothing... also wondering how to do a factory reset cuz if i didn't screw the phone up yet, i will :) thx in advance

Has you can see I'm new here. I'm old and retired I would love to root my ZTE Merit 2.3.5 but this is over my head.
I was wondering if there's any accomplished phone rooters in the NC area that would be willing to walk me through this or do this for me
I'd be more than willing to make a donation to make this happen,

Not working

I can't even get past step 2, I have the file installed and unzipped on both my computer and my smart phone. The only thing I can find to put in the codes is command prompt which says "error: device not found" when I type in adb shell. My ZTE Merit phone has very low internal memory due to all the retarded system apps that came on the phone, I would very much like some assistance removing them from my phone. I also downloaded superuser elite onto my phone and it doesn't show up with ANYTHING. The first page says
superuse v3.1.3(46)
tap to display changelog
elite installed
su binary not found
a check in the box "outdated binary notification
unchecked box, temp unroot (When tapped it does nothing)
unchecked box ota survival (Again when tapped it does nothing)

I scroll over to the apps section of the program and it says "No apps in list"
What am I doing wrong? This lack of space is quite irritating
 
SIM Carrier unlock a ZTE Merit Z990G Straight Talk

I'm currently a T mobile prepaid customer and received the Merit from a friend of mine for doing some painting. I have looked for a month now and had a few unlock websites fail at attempting to unlock the phone via the IMEI (which the phone does have ). I have attempted to put my tmobile sim in the Merit but there is NO place to enter an unlock code. I really DONT wanna change my service to straight talk and would be willing to pay a decent amount to anyone that is capable of unlocking this phone for use with tmobile. If you think you have what it takes PM me and i will give you the IMEI and we can work out a deal. I challenge ANYONE achieve the impossible and get me the unlock code and a way to input it into the phone.:eek:

Can't get SU to upload

Hey I'm new to rooting android. I get to the point of installing SU but windows keeps telling me file not found. Would really like some help in fixing this issue. I have installed SU file to C:\Android\android-sdk\SU. Up to this point everything works fine.
adb push su /system/xbin/su
adb shell chown 0.0 /system/xbin/su
adb shell chmod 06755 /system/xbin/su
Any help would be really appreciated.
Thnks

Help getting Started

Hey Anyone and everyone that may be online, I have a real quick and probably REALLY EASY question for ya... I'm trying to get started Rooting my ZTE Merit and I need to find out how to get to or where to find the screen where I type in the commands. I already downloaded the chainsdd zip file. So now I'm supposed to get shell with adb. If someone would be so kind and put me in the right general direction, I sure would
be grateful.

Thanks in advance,
Jason
