I've noticed that since I've rooted when I go to the Android Market it doesn't show any of my apps as "Installed". They all seem to still work but it's like the market no longer regnizes what I have on my device. Is this normal?

I'm right there with you. I just can't get the #. I've tried at least 50 times. I'll put it down for a couple of weeks and give it another go, same deal, damn $. I've tried running SuperUser while doing it and still no dice. Even tried numerous times adb shell after the first reset of the phone.

What else could it be?

I'm not sure what the problem you are having is, as I got mine rooted on the first try, but it seems that many people's problems are due to some sort of adb issue between your phone and computer. You can try rooting (and anything beyond that) without using a computer, which would eliminate adb altogether:

I have used z4root on multiple LG Optimus S with no problems. I do understand it is better to understand whats going on but after the headache its just so much easier.

Use z4root, it works. I think what people are missing when using z4root is you have to run 'su' in 'adb shell' then go to the phone and ok the request for root. After that, you will have # in adb shell.

I tried these instructions too, endlessly before using z4root and have flashed the custom recovery as well as a custom rom with no problem.

This post from devilspy really helped me when I was having problems:

Yea I Gave up after 20+ tries, and just used z4root. SOO much easier. I wasn't doing anything wrong, as soon as I rooted it I had no issue gaining su privileges. Popup did come up asking to grant.


C:\android-sdk-windows\tools>adb shell
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
$ su
su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system


C:\android-sdk-windows\tools>

As pbmlt just mentioned, if you type "su" after the "$," then you should be able to get the "#."

Must be doing a noob thing here, but here's what i get when trying to root: I copy and pasted adb push rageagainstthecage-arm5.bin /data/local/tmp/rageagainstthecage at first line-by-line, then up to exit. What I get back is 'adb' is not recognized as an internal or external command, operable program or batch file.

WHAT AM I DOING that I can't even make it past the first step?

Windows computer? Are you in the \tools folder or the \platform tools folder? If you were in one, go into the other instead.

If you have an epic, try the EPIC forums as they will be more beneficial and device specific. I am not sure if this exact script will work on the Epic.

It took me a few trys, but if you read through the entire post youll find an answer.

My fix was simple - after i pushed all the items and ran ./rageagainstthecage and it kicked me off adb, i closed it all off. by this i mean I closed the application, and also checked the task manager (ctrl + alt + del) and looked for adb.exe looking in the process. It stayed dormant, so i ended its process.

Once it was all closed, I reopened the SDK Manager, then opened another command prompt.

If your having problems navigating or locating "adb", simply look through where your sdk is installed, and look at all the folders. for me, i started with a :tools: folder, but there wasnt adb.exe in there. After I ran the SDK manager and updated everything adb.exe was in a folder called platform-tools. This is where you should copy rage...,su, and busybox.

back to the command prompt - navigate to the folder with adb and run adb shell.

this worked for me - Win7 platform. Im pretty sure it will work for you too. I tried z4root - but again, it would not give me root access because i didnt realize that adb stayed dormant.

Use adb's command prompt - itll help you understand the process better (as is recommended). I know this thread has been beaten with a stick many times, but i hope i helped someone out

If you can access the phone from adb then no but if you can't then yeah you will need to.

 

[scooled101]

thanks beezy i guess i will give it a shot and see what happens but if i open sdk the black screen is there then the update manager pops up the only way i can keep the black screen from closing is to leave the manager on also, if i close the manager the black screen will close also

Okay gotcha, it's seems like it's making you update.You want to install the "platform-tools" then where it say in the guide to use
(android-sdk-windows/tools) instead us (android-sdk-windows/platform-tools) or whereever you have it installed.

i understand what you are saying but it just lets me update where its at it will not let me change where it is going to update and store, the only thing it will let me do though is choose what i want it to download. and it has platforms starting at platform 1.5 up to2.3 then the documentation kinda off beat of the instructions i guess haha this threw me in a big loop

Let it find the available updates then just click cancel. Don't install them. The sdk comes with adb, you don't need all the other stuff.

 

[scooled101]

the screen is black with a cursor and will not let me type at all though

 

[KSmithInNY]

It's supposed to do that. Now open a cmd prompt, you use this, not the one sdk opened.

Your at the start of step 4

 

[scooled101]

also says cannot find the filename specified so i take it these files have to be downloaded sorry to be a pain
