Rooting fails - LG G Pad X 8.0 Questions & Answers

The rooting instructions are here. Everything went smoothly before this command: "adb logcat -s recowvery," which hangs forever. I've repeated the same root process to many times to count and it always fails on the same command.
Does anyone have a solution?
Thanks

Cant access recovery or boot phone - Have screwed up?

Hi Guys.
I don't know if this is the right forum, please tell me if so.
I think that I've screwed up bigtime when i tired to upgrade my recovery image. Here is what happende.
I have rooted my Hero a long time ago, so what i did was trying to follow this guide for installing the latest recovery image: http://forum.xda-developers.com/showthread.php?t=645253
when i tired to flash the recovery image using this command: flash_image recovery /sdcard/recovery.img. I was using Terminal Emulator.
What happened was i got a lot of error messages saying that the phone was out of memory. This resulted in that i couldn't get acces to the recovery menu when rebooting my phone and that i cant access my phone rom.
I then tired to flash the recovery image using the installation guide of this thread: http://forum.xda-developers.com/showthread.php?t=561124
The thing is that i can see that the phone is mounted through the "fastboot devices" commando
When i try to flash the recovery image using fastboot i get this error message:
C:\android-sdk-windows\tools>fastboot boot recovery.img
downloading 'boot.img'... FAILED (remote: not allow)
finished. total time: 0.001s
HELP! What can i do? Is my hero 'saveable or is it bricked?
//Mads
First of all its not bricked don't worry. Do you still have old recovery of Amon_Ra or not ? If have than put latest version of Amon_Ra recovery into your sdcard & reboot your phone into old recovery of Amon_Ra Than just follow these commands
Code:
adb shell
$su (not required if you have root already)
#mount -a
#flash_image recovery /sdcard/recovery-RA-hero-v1.7.0.1.img
when its done just type adb reboot . your phone will reboot
Hope it helps
Hi, it's good to hear. I think that my old recovery mode was screwed up during the attempt to upgrade. because if i tries to boot into it it just stops at the HERO bootscreen and goes no futher. If i just try to boot normally it goes to a black screen and then nothing else happens. Tried to let it boot for 30 min without anything happening.
The only thing i can access is fastboot.
when i try adb shell it says the following:"
C:\android-sdk-windows\tools>adb shell
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: device not found
you need to update your drivers that means you are not having latest drivers .. there was a thread i guess download drivers & check how to set up correct adb drivers on windows .. & by the way do you have installed HTC Sync ? make sure you have installed HTC Sync because it finds all htc drivers i guess than try
Code:
adb shell reboot bootloader
fastboot boot recovery-RA-hero-v1.7.0.1.img
adb shell mount /sdcard
adb push recovery-RA-hero-v1.7.0.1.img /sdcard/recovery-RA-hero-v1.7.0.1.img
adb shell flash_image recovery /sdcard/recovery-RA-hero-v1.7.0.1.img
adb shell reboot
Thx for the help, but that didn't work either.
I found this guide http://forum.xda-developers.com/showthread.php?t=714519 which did the work. So now i'm back at 1.5 for a little while, just need to root right away The good thing is that my phone is working
Thx for the help.
Glad to hear it Men .. Well come abroad

My method for S-Off on a 64bit OS (lengthy sorry).

This is the method I used to S-Off several devices (8 in total) on Windows 7 64 bit.
Remember, Team Unlimited does not recommend that you use any OS that is not supported as the drivers can cause some issues.
I have included a method that will test whether your drivers in your current setup will perform in a way that reduces the chance of all hell breaking loose.
Before starting, make sure you have downloaded and installed the HTC drivers for your phone and have Adb downloaded. A great place to get this is from “Team fireballas FakeCid AUTOMATIC bootloader unlock” thread.
We will need this file for a later process as well. (File Download)
Once downloaded, unzip it to C:\Root.
Verifying that your drivers are working correctly. (Typed commands are in red)​
1) Attach your phone to you computer with the supplied USB cable.
2) Enable USB Debugging (Settings>Developer Options>USB Debugging)
3) Open a command prompt and navigate to the location you extracted the adb files to by typing: cd\
Then type: cd c:\Root\stuff
Your Prompt should read:
c:\Root\stuff>
4) Now type adb devices
You should see the following output in the command prompt.
C:\ Root\stuff >adb devices
List of devices attached
HT26KS311633 device
Your device will have a different device ID than what is listed above. Just make sure it shows a device ID and device listed after it.
5) Now type: adb reboot bootloader
At this point your phone should reboot into the bootloader with Fastboot selected.
6) Type: fastboot devices
You should see the following output in the command prompt.
C:\inc4>fastboot devices
HT26KS311633 fastboot
Ensure that your device is listed. Your device will have a different device ID than what is listed above. Just make sure it shows a device ID and fastboot listed after it.
7) Type: fastboot reboot
You should see the following output in the command prompt.
C:\inc4>fastboot reboot
rebooting...
finished. total time: 0.070s
Your phone should be rebooting.
You have now verified that your drivers are working correctly even after rebooting into fastboot.
At this point I cannot give you alternative instructions per Team Unlimited. So follow the directions listed HERE.
When you reach step 12 which states:
“Temproot your phone via any method available - we cannot help with this step and it is REQUIRED!”
Follow the following steps that were originally written by captainrewind in the “Team fireballas FakeCid AUTOMATIC bootloader unlock” thread.
Go to Settings -> Connect to PC and change Default connection type to Disk drive and disable Ask me.
Navigate to the folder in the command Prompt by typing
cd c:\Root\stuff
Now that you're there, type:
adb devices
If your phone pops up in the list, you're good to go!
Next, type
adb restore fakebackup.ab
DO NOT click OK to the restore on the device just yet!
Now type:
adb shell "while ! ln -s /data/local.prop /data/data/com.android.settings/a/file99; do :; done"
(errors will appear, ignore)
Accept the restore on the device, then type:
adb reboot
(At this time, you are temprooted, and the phone UI will be in an unusable state, with temproot shell.)
After reboot type:
adb shell
Verify that the prompt is "#" (meaning root) or "$" (meaning normal user). If it's not "#", please start over.
You can now return to Team Unlimited’s instructions and continue with step 13.
This should take you the rest of the way to S-Off.

Excellent suggestion and great advice. Always make sure your computer can recognize your device in all device states before attempting root.
I found the hard way on a Kindle Fire and now always do this test (a couple of times) to make sure the device being rooted can be seen in all states by the PC. For whatever reason, my (original) Kindle Fire has a different USB Enum for each state and my Windows 7 64-Bit computer didn't recognize it in fastboot which caused a lot of irritation.
This is helpful but I believe unlimited specifically asked not to have any other how to threads

This isn't a how to about Unlimited's process. And frankly, they can request anything they want, but they will not control other peoples threads. They were talking about their own thread.

I'd like to comment on this part, since it threw me off a bit and scared the daylights out of me.
After you issue the "while..." command, you'll get infinitely scrolling errors/warnings, or at least I did in Ubuntu. Just ignore them, nothing is wrong. While they are infinitely repeating in your terminal, just accept the restore on the phone and they stop. I don't remember the exact text of the error, but if someone could put it here that would probably be helpful to anyone wondering.
Very cool. Thanks madmoose!

Will this make my laptop s-off

Only if your laptop is an Incredible 4G...
Add me to the list of S-OFF via Win7 64bit. I restored my Viper TWRP backup and all is running smootly. Now, I am off to customize my bootloader with RegawMOD Bootloader Customizer.
Used a modified version of this to achieve s-off but what really helped me was the "Verifying that your drivers are working correctly." section. When I had tried unlocking earlier I keep getting stuck in the error looping screen when restoring the fakebackup. This little set of instructions pointed me in the right directions for getting the drivers installed correctly.
Many thanks MadMoose and Happy New Year! :victory:
Many thanks to MadMoose. Everything worked for me on Win7 64bit as well, and would have worked more smoothly if I had done it your way
Yesssssssssssssssssss
Wow what a journey, used it on my 64 bit computer per another post here that gave a very nice detailed instructions. had to relock, temproot, s off, flash recovery, and then restore... but i would do it 100 times again! thanks everyone for your activeness in this community, hopefully it continues to grow
Has anyone tried to get s-off with Windows 8 x64 yet? I copied in the drivers, tried all the commands, and they replied normally. Will I brick my phone if I try?
I'm afraid it won't work unlimited said that 64 win7 wasn't officially supported it just happens to work
It may work but unlimited won't help/support you if you have problems.

I'm just wondering if it doesn't work, then am I bricked? Or can I just pull the battery and restart?

Went ahead with s-off in win 7 x64. Success!

[Q] Terminal Command "Stop". Phone not boot up.

Hi everyone! Please help me. I've accidentaly typed in Terminal Emulator commad "stop" with SU permissions and my phone first freezed then don't want to boot up. How can i start my phone? I can access only recovery and fastboot.
Edit: Also i can run adb commands. So the question, what command i need to run for start phone?
If you have access to fastboot you could simply use RSD Lite to reflash your phone to stock.

I don't want to flash stock then again set everything i need. I just need a correct command to run thru adb for start.
It's like "adb start" or "adb shell start", i don't know.

Honestly, i never heard of the command "stop".
You could check the documentation for adb.
Edit: There is a command called start which "restarts execution of an emulator/device instance."

Can also connect that bad boy of yours to comp and run start command in terminal. I have done this too. I also ran bootanimation in android terminal, continous bootloop. But fun is had running those xbin/bin commands. Lol
XT912 RaZR SpYdEr CDMA
hit ThAnKs if I was helpful!!!
I have done this stop command too but my phone still boots up normally it just goes blank and my touch buttons are lit up and all I did was power off by holding power button for 6 seconds and power back on and booted up normally ? I'm alittle scared to play with commands now because I was just typing all random root user commands and I went through a bootloop like 5 times and I reflashed through RSD lite but I know now that I shouldn't play with those cmds now??

How to fix adb (error:closed) and fastboot (waiting for device) in cmd

Hi there!
Please help me...
My Infocus M210 is rooted and I've edited the build.prop from a build prop editor to speed up internet data connection but the editor goes wild and changes everything written on the build.prop then forced my phone to shut down and when I start my phone, it stuck at boot loop.
I've already wipe data/factory reset on its built-in Android system recovery <3e>.
but I think its the worst thing that I've done.
Coz I thougt it disabled debugging and removed root permission from my device.
I've used Apply update from ADB.
I tried to sideload stockrom.zip but when its completed sending on my phone, then says "installation aborted" I've tried different ROMs but same result.
I have also tried shell commands:
adb pull /system/build.prop
adb -d -e -s <serialNumber> shell am start options -D
but all shell commands doesn't work and says "error:closed"
So then I've tried Fastboot mode
but my devices wasn't found
so I have followed some threads and watched youtube tutorials:
So I removed drivers via "usbdeview"
Then installed Fastboot device/ Fastboot interface drivers manually.
but I almost tried all drivers from official to many google drivers
but still my device wasn't found in cmd
says "waiting for device"
Now I'm thinking if there are some tricks to fix adb "error:closed"
or try different computers for fastboot
I already used my Windows 7 64-bit from my friend
and Windows XP 32-bit from my friend
Please Help me...

Galaxy S4: ADB recognizes device when normal. Although not recognized in bootloader

Hello everyone!
I am currently having issues with my Galaxy S4. I am attempting to install twrp onto it although I am having issues. I have not made any modifications to it, it is running the stock rom and it is not rooted.
I am following this guide: https://www.xda-developers.com/how-to-install-twrp/
I installed adb and fastboot using: https://forum.xda-developers.com/showthread.php?p=48915118#post48915118
I have not gotten any errors.
I type into command prompt:
adb devices
I then get my devices id.
I then type adb reboot bootloader
Once it finishes going into bootloader.
I type adb devices and then get nothing.
I also tried typing fastboot devices and also got nothing.
When I use flashboot flash recovery it gives: <waiting for device>
Could anyone help? I am a newbie at this.
Thank you!
