[Q] link_image[1995]: failed to link su CANNOT LINK EXECUTABLE

Long story short is that yesterday I rooted my HTC Glacier and everything seemed to work fine. I was able to obtain admin privileges by opening a Android terminal and typing "su". Today after deleting a few files from my phone which I thought were junk (face palm) I go into terminal to check if the "su" command still works and I get the message "link_image[1995]: failed to link su CANNOT LINK EXECUTABLE".
I've checked and my s=off is still in place so it's not that that's causing the error message. I'm new to Android so I'm stumped as to what steps to take next in order to regain my admin privileges.
Thanks for any and all advice XDA Community.
Cheers!

Try re-running visionary. It won't hurt anything and it installs su, busybox, and superuser.apk when you run it. It won't mess up anything you already have installed and it might fix your problem.
Also, I'm sure Whosdaman will tell you and move the thread when he sees this but make sure you post questions in the Q&A section.

Ran Visionary and no dice. Thanks for the tip though and sorry for posting in the wrong forum.
Any other ideas?

Try going into xbin (cd /system/xbin) and typing ls and see if su is in there. If it is you could try running rom manager and "fix permissions" if it will let you.

Good deal. I'm actually out fixing someone else's desktop computer at the moment. I'll attempt your advice later tonight.
Thanks again.

Ok, had a free moment and was able to run ls, su was there but unfortunately I wasn't allowed the super user access needed to fix permissions.

Please post questions in Q&A section.

1. Go into settings-applications-manage applications and try clearing superusers cache/data. See where that takes you.
2. If that did not work - isntall a fresh copy of superuser app from the market and once more see where that takes you.

Sorry about that. All future posts of these sorts I'll be sure to put there.

Tried both of your tips but unfortunately am still getting the same error when I run the "su" command.
Any other thoughts?

Update: Superuser automatically downloaded a new binary and told me to unzip it in recover mode.
I went into recover move and attempted to unzip the binary and was greeted with an error message that said the file couldn't be unzipped because it was "bad".

Can you get su in adb?
The more I think about it, You're s-off so you can fastboot new recovery image and then flash new rom with all the goodies preinstalled. May be the easiest route.

To be honest I've had my pocket computer for all of a week, so I'v still not had a chance to play around with adb.
The whole reason I rooted in the first place was so that I could flash custom roms. You think I'll be able to flash even though "su" privileges don't seem to be working properly in my current rom?

Update: It's clear from reading around these forums that the way to get to know your phone and thus be able to fix it is via adb. So I'm installing the Android SDK now. Thanks for all of your help Borodin1 and Grankin01

[RESOLVED] Stubborn security on MT4G. Will not Temp-Root.

I was able to root my MT4G with ease using VisionARY r14. My friend purchased a MT4G shortly after and I was trying to root it for him, I used several methods and no luck on any of them.
I've tried using:
1. Visionary temp root>attempt perm root
2. Visionary temp root>terminal (sh root.sh)
3. Visionary temp root>terminal (/data/local/wpx.ko)
From what I understand #2 & #3 basically are the same. So going back to the problem, on MY phone (I don't recall if I used #1 or #2), I rooted with no issues. On his phone, the root is not sticking, every time I go into the bootloader on his S=on still. Nothing stands out or is out of the ordinary, and I would think it would have rooted just fine, the scripts ran via terminal emu and looked okay and all.
Something else I've noticed is when I install CWM Recovery via ROM Manager, after temp root from Visionary the install of CWM Recovery itself was fine, though after going into bootloader and trying to access recovery or booting into recovery from ROM Manager, it doesn't go into recovery, I get the cell with red triangle and "!" on it. I'm assuming that this is a result of it being unrooted still? Anyone else run into a stubborn MT4G like this? I've attached 2 pictures for visual aid of the phone's bootloader screen and about screen below.
Any suggestions or help is greatly appreciated, I've been trying to root it for over a week now and no luck.

I can't see the pics you posted, but I had this issue myself, for me the answer was to find a stock recovery pre ota update and force it, then I ran visionary and terminal with sh root.sh or whatever... Hope this helps... Just try to find an image of pre ota stock rom and go from there... There is a good forum here with a walkthrough to do this... Post results please, would like to know if this was your issue...

Ok guys, first of all Scotty2 gets all the credit for the program R&D. I used my device as a test bed and have tried a couple different kernels (Gr8Gorilla's O/C Kernel and the stock kernel).
Now for the boring stuff ...
This is a very invasive way of rooting your device but the benefit is TRUE S=Off and root privileges throughout the system. As such, you do this at your own risk and if you brick your device neither Scotty2 nor myself are responsible, YOU ARE!!! Do this at your own risk!!!
This is not for the faint of heart and if you have any reservations about doing things like this do not do it.
This process will do three things for your device. I will explain them here:
1. It will set up Super CID on your device allowing you to flash any carriers rom (not just tmobile). Giving you more freedom with your choice of software. The software still needs to be device specific to the glacier for compatability reasons though. Like vodafone glacier roms etc.
2. It will subsidy unlock your device. In other words, it will SIMUNLOCK your phone allowing you to use an AT&T sim card and so on in your device without needing the unlock code from HTC.
3. Most important of all it will turn the RADIO S=Off. This is the ultimate S=Off because the radio is what controls the security flag in the first place. Once you turn it off here it is off everywhere and will allow you pure unadulterated access to your device.
This process will not change your bootloader (unless your on 0.86.0000 and you follow the optional steps).
Now, you may be asking "Why do this? I already have root from your other guide and it has given me r/w access to system and recovery. I thought this meant we had permanent S=Off." This is only partially true. We have had an engineering bootloader and "Label" s=off not radio s=off. When you turn the security off in radio it is off permanently no matter what hboot you have installed engineering or otherwise. However, it is optional but you can still copy the engineering hboot over and it will allow you to flash whatever you like without (as much) fear of bricking your device.
This guide assumes you know how to use ADB. If you do not there are guides all over XDA to show you how. There is even a really good one in this forum. Also here is a video on how to setup adb discovered by topgun303: http://www.youtube.com/watch?v=1UF5w1dKe2U
*NOTE*
For some reason this process can bork your recovery. If you notice after following the steps below that in order to reboot from recovery you have to uninstall/reinstall the battery and hit the power button, just install/reinstall clockwork recovery through Rom Manager in the android market and it will fix your problem.
CONFIRMED: Guide does work for pre-OTA devices!!! Thanks xanz!
Here we go:
If you are already permarooted per the other guide just follow the first 11 steps.
Make sure you have visionary installed on your device. (If you were already permarooted w/s=off ignore this step.)
Download this file:
http://www.mediafire.com/?s7afymwe2wb3x60 New version of gfree with more options! See below.
md5sum: b73c56ca0e21664c5756d4ad295063c5
1. Now unzip the file into your SDK tools directory.
2. Plug your device into your computer.
3. Now open explorer and hold down shift at same time you right mouse click on your SDK tools directory (platform-tools if you have the R8 version of the SDK). Select open command window here. If you are in linux (ubuntu) right mouse click on your SDK tools folder, choose actions, and choose open command window(or whatever it's called). Otherwise, open a command prompt and cd your way to your SDK tools directory.
4. Type "adb push gfree /data/local" and hit enter.
Optionally, you could dl the file to your phone use androzip or something like it to unzip the file and then use root explorer to move the file named gfree to /data/local. Not the gfree.h file. All the other files are source code inlcuded for the gnu license. This would skip the first 4 steps.
5. Now unplug your device from the computer.
6. Run visionary to gain temp root. (If you were already permarooted w/s=off ignore this step.)
7. Open terminal emulator on your device, type "su", and hit enter to gain root privileges.
8. Type "cd /data/local" and hit enter.
9. Now type "chmod 777 gfree" and hit enter to make the program executable.
10. Type "./gfree -f" and hit enter.
New features in gfree.
gfree usage:
gfree [-h|-?|--help] [-v|--version] [-s|--secu_flag on|off]
-h | -? | --help: display this message
-v | --version: display program version
-s | --secu_flag on|off: turn secu_flag on or off
-c | --cid <CID>: set the CID to the 8-char long CID
-S | --sim_unlock: remove the SIMLOCK
With the new features you can turn off one thing at a time. You can also turn security back on and set the CID back to stock if you wish. To turn simlock back on you still have to follow the revert procedures on this page as the information that is patched to turn the lock off is encrypted and we can't write back to it other than restoring the entire image.
So, if you wanted to leave simlock on but turn security off and set super CID the command would be "./gfree --secu_flag off --cid 11111111" + enter. The -f switch after ./gfree that is now in the above step (./gfree -f) just tells gfree to patch everything.
11. Wait for the program to finish and then reboot into HBoot to see if S=Off. Also, check your bootloader version. If it says s=off and has bootloader version 0.86.0000 it worked.
If you already had hboot 0.85.2007 you can check it through the hboot menu. It gives you an option for "system info" in the hboot menu. Highlight it and hit power. It should say CID = 11111111 or something like that. If it does your golden.
Congratulations!
12. If this is the first time you have rooted your device you will need to run visionary again (temproot w/set system r/w after root checked and then attempt permroot) to make root privileges permanent and then reboot again. Now "su" should work properly for you.
Gfree writes a backup of the file that it patches named Part7backup-numbers.bin on your sdcard. I suggest putting this file in a safe place as it is the only way to revert if you need to.
[Optional] Steps to flash engineering bootloader.
1. Restart your phone and plug it back into your computer.
2. Download this file: http://www.megaupload.com/?d=NN5726Z8
md5sum: df4fd77f44993eb05a4732210d2eddc6
3. Copy the file to your SDK tools directory.
4. Open a command prompt again and cd into your SDK tools directoty (platform-tools if your on the new R8 SDK).
5. Type "adb push hboot_dhd.nb0 /data/local" and hit enter.
6. Now open terminal on your device and type "su" and enter to gain root priviliges.
7. Type "cd /data/local" and enter.
8. Now type "dd if=hboot_dhd.nb0 of=/dev/block/mmcblk0p18" and hit enter.
9. You should see something like: 2048 bytes in 2048 bytes out 1048576 bytes copied blah blah blah.
10. Now restart the device into hboot and check if your bootloader version is 0.85.2007. That is what you want to see.
Congratulations, you now have a TRUE root and engineering bootloader on your shiny MT4G!!!

Please Help! Permanently Root MyTouch 4G

Hello,
I have been trying to figure this out for over 24 hours. I feel like I am so close yet so far. I have watched video after video, read guide after guide and still no luck.
I have tried the adb method (no luck whatsoever) and the root folder + visionary and cannot get my phone to permanently.
My android version is 2.2.1
I have Root File Manager installed
I have Super User installed
I have Visionary r.14 installed (tried MULTIPLE versions)
TempRoot works fine until my phone reboots (which is supposed to happen) but when I press Attempt PermRoot my phone reboots and it goes back the to the way it was unrooted.
My goal here is to put a new ROM on my phone (i.e. GingerBread) or something like it.
Can someone PLEASE help me?
Thank you in advance
Matt

Use this thread. Follow the instructions to the "T" and you will be fine. It is very simple and pretty much dummy proof. This is the g-free method. I have rooted 3 phones with this method with no issues, and this is my first Android phone. Good luck!

Thank you very much! I did get it rooted and I am working on installing my ROM. That was a very quick response, Thank you

You are very welcome.

i dont mean to sound like a noob, but can you push the gfree files to data local by using the terminal on your phone correct?

I haven't used the gfree method but you need atleast temp root access to make data R/W (read write) so unless you have temp root no. But if you do it'd be easier to just use a root explorer.

[Q] LCD Densitity help..

Hi, I recently rooted my X10 mini pro using Z4ROOT, I then messed around with a few settings using liberty tools, I changed the LCD density and now my icons are big and ugly, I cannot change the density back to 120, it just stays the same.
I have also tried to root it properly using android SDK, however, this has no success at all at rooting my device.
I have tried copying and editing build.prop (I opened it up on notepad and changed the density value to 120) and tried to paste it back into system, would you know it I dont have permissions.
I have also tried to edit the original build prop file using a text editing app i have installed on my device.
How can i change my LCD Density back to its original state??

flash back to 2.1 with flashtool and then use the flashtool to root. You don't need superuser permission to get into flash mode. You obviously didn't really root the device or you would be able to grant SU permissions. Also there is an X10 Mini Pro forum you should have posted there.

Download a program called usbdeview. Open up the program (run as administrator) and delete all of the drivers associated with your phone. Make sure USB Debugging is turned on in your settings/applications and plug your phone back into your computer. This should download the drivers necessary to run ADB.

Just use this

Try using one of splash screens that are on this site already so you can tell if there is something wrong with the file that you are using or if you are missing a step. You can always replace it later once you know what the problem is. I'm thinking that if it's saying that there is no such file that may be the problem with the file. Did you unzip the file from the folder and put it on the root of the sdcard?
