[Q] Complete noob, grateful for root help

Hi .. would really like some help as I got a replacement G2 and I need to return my broken phone back tmrw and would like to root it.
I actually rooted my first g2 using temp root/visionary about a year ago...
but now I can't seem to understand the wiki's or any guides on how to root my phone again. . help!
Tried the AMT way, says device is not connected
Currently trying to use this guide : http://forum.xda-developers.com/showthread.php?t=1107911
I can't even get past the first step.. in the command prompt I get
"*daemon started successfully*
error: device not found
any help would be appreciated.. sorry I am a complete noob at this

Do you have the HTC Drivers installed? Do you have Android debugging enabled on your phone? I don't know if it matters but I think your sdcard shouldn't be mounted when you connect it to your PC.
With the above things done, you should be able to type
adb devices
And it should list your device and its serial number.

You probably need to install drivers. I'm assuming you're using windows?
You can get the driver package here
You'll need to downgrade first with this guide
Then I recommend the wiki method to root
-Nipqer

I just downloaded the HTC drivers
i'm following the downgrade guide now
i downloaded the 2 files and put them in the platform-tools folder
already having trouble with the first step
"Run the following command to verify the exploit has access to what it needs. (Only the first line is the command. The second line should be the result returned if all goes well.)
Code:
> adb shell cat /dev/msm_rotator"
where do i type this command?
"> adb shell cat /dev/msm_rotator"
sorry if i sound like an complete idiot.. i have no clue what to do.

alright, i read through some of the adb for dummies
when i type in adb devices i do not see a serial number.. but i've installed the htc drivers already
is there something else i need to install? thanks
edit:* Yay i just got the drivers working, serial number is now showing!
edit 2: i had no idea what i was doing... somehow got through the instructions, downloaded some pda drivers, followed the guides and now my phone is rooted!
i felt like Neo typing in the codes... Thank you guys. Thank you XDA!!

Glad to hear you got it sorted out. Sounds like a good learning experience

I cannot unlock my Samsung Galaxy S I9000

Hi guys I have been trying to unlock my Samsung Galaxy S I9000 for some time now with no luck. I have tried two (samsung unlock and the xda) methods and both has failed. There is a problem generating the codes. Maybe I did too much flashing in the begining I don`t know . Can anyone help me with this please? I have added a jpeg to see if that helps.

you get permission denied error ..
do this in terminal
Code:
adb shell
su
chmod 777 /efs/nv_data.bin
exit
exit
after this you can
Code:
adb pull /efs/nv_data.bin

Thanks for the quick response. but bare with me cause I don`t understand the instructions. How do I go about doing it in terminal?

I unlocked my SGS by using an app called Galaxy_S unlock by Helroz from the play store.
If it doesn't work try downgrading to froyo as I unlocked mine when I was on 2.2.

It seems you have adb.exe tool already installed but you get error because you do not have enough rights on your phone so get the rights by these lines..
by terminal here I mean cmd.exe from Windows
so enter cmd Start/Run/cmd.exe
then to start adb server enter this
Code:
adb devices
then in cmd enter
"adb shell" press Enter (in fact this is "terminal" - a way to get access on your phone and enter commands)
then "su" press Enter
and so on..
Code:
adb shell
su
chmod 777 /efs/nv_data.bin
exit
exit
lastly enter
Code:
adb pull /efs/nv_data.bin
now you get nv_data.bin on your PC check for this file in the folder where adb.exe is located usually ~\android-sdk\platform-tools\adb.exe
You have the advantage of a well-known phone so there are solutions for everything
by example look here for a tutorial to unlock your phone
If you do not understand something let me know about
This is the case you want to work from scratch the easy way is to search on Market/ Google Play for an app to unlock this phone

Wow it is not easy to get past this image verification at all. Anywho............ So I have properly installed the SDK and I also installed a stock rom (I9000XXJP2) and rooted it and Now I get this result displayed in the attached pic. I have tried to follow the instructions given by ruscan.calin (and thanks for the "look here for a tutorial to unlock your phone" link) but I again I am back at a dead end.

replace on phone and give rights follow that tutor
I can help you but give me more details because I don't have this phone

I installed the SDK and put in the path for the ADB folder. Then I installed a stock rom (I9000XXJP2) and rooted it although I think I did not have to root it. I then used the "Generate_Code" script from XDA. But I still don`t get the NCK and Freeze codes. Should I try another rom?

root is very important if not you can not play with nv_data.bin file...
what link ? and how did you do what steps I can't guess show me some logs screenshots anyway more info !

Then from the DOS command prompt:
adb pull /efs/nv_data.bin
Step 5: Select the file on the main Samsung Galaxy S Unlocker & Repair page
Step 6: Enter your desired Unlock and Unfreeze Codes and click the SUBMIT button
Step 7: Download the new file that is generated for you
Step 8: From ADB shell (Type "adb shell" at the DOS command prompt) or a terminal on your phone, enter the following commands to backup your current EFS related files, in case something goes wrong. ![/QUOTE]
After I have followed the instructions up to "steps 4" I am not sure what I should do for steps 5,6, and 7. I don`t know where "the main Samsung Galaxy S Unlocker" is. I included two pics of tmy adb shell (adb pull /efs/nv_data.bin)
I also copied an efs folder from my phone onto my pc.

My sincere apologies to you my friend. I was able to unlocked my SGS after I followed your advice of downgrading to froyo and then I continued with the tutorial I got through Member ruscan.calin. So excess amount of thanks to you both. I will make sure to properly BACKUP my SGS3 before I touch it. I have learnt my lesson. Thanks again.

Hi,
You can unlock your Samsung Galaxy S I9000 using unlock codes!! Unlocking using codes is easy and also safe!! You can get the codes from your service provider or from reliable online sites!!!Personally, I would suggest prounlocking.com , here they provide accurate codes at reasonable price!!!

On linux, sometimes you need to mess with one of the virtual filesystems for it to see the device. I can't remember how it works now, but you add a file with the manufacturer id and product id.

Cheers for the info is it this what you are on about sudo adb kill-server if so i have tried it and it only shows the device when powerd on i have had a little play this morning before going to work still no joy I really want to unlock this device and flash a better rom than uk's O2 rubbuish but it feels like i am hitting my head against a brick wall. Any how thanks again this community rocks well of to work i go

hello,
I did it last week...
try
Code:
./adb reboot bootloader
the important part if you just unzip the "android/sdk/platform-tools" it that you put "./" before adb and fastboot commands and eventually before folders's paths
Give it a try.

Cheers will give it a try tonight when I get home @ work now and knackered lol

There's a possible fix until the moment you flash persist or restore EFS from another phone to yours.
ONCE AGAIN, DON'T TRY TO FLASH PERSIST OR RESTORE EFS FROM ANOTHER PHONE!!!
Just root your phone using Magisk and execute these commands using adb on your PC/laptop:
Things to note before you start executing commands below:
1. Make sure that USB debugging in your phone is turned on.
2. If everything is set properly and "adb devices" has been executed, u should see popup window about ADB allow on your phone BUT ONLY IN CASE YOU ARE USING ADB ON PC WHICH WASN'T USED FOR ADB YET. Make sure "Always allow from this PC" is checked and click "OK". Re-run command one more time. You should be able to see your device in cmd window now.
3. After "su" command, you have to grant root access to adb shell within 10 seconds.
4. "adb reboot" command will immediately reboot your phone, don't panic.
5. You are doing this at your own risk.
Code:
adb devices
adb shell
su
chown -R rfs:rfs /persist/rfs
chown -R rfs:rfs_shared /persist/hlos_rfs
adb reboot
Commands have been used from this thread: https://forum.xda-developers.com/g5-plus/how-to/fix-persist-resolve-imei0-explanation-t3825147

Good morning!
Look I was able to recover the signal (h +) with that command but not imei. Will not you know other commands that will make him recover or some method? regards

Pixel 3XL adb works, fastboot not seeing phone?

I just bought an unlocked Pixel 3XL from the Google store.
PC is Linux Mint 19 with both adb and fastboot installed.
I have developer mode, usb debugging on. PC has been granted permission to debug.
I am stuck trying to unlock the bootloader.
$ adb reboot bootloader --boots the phone into the boatloader as expected,
Device state: locked
Power button options do not include: Unlock Bootloader
$ fastboot flashing unlock --returns: < waiting for any device >
$ fastboot devices --returns: no permissions (user in plugdev group; are your udev rules wrong?)
Seems that adb can communicate with the phone but fastboot does not see the phone... I have been searching for further info on adb/fastboot, but so far no joy.
Can anyone recommend a solution or further troubleshooting in this situation?

This happens because the device drivers are not completely installed.

As stated, the user trying to execute the command has not been added to the udev rules.
Basically, you'll need: usermod -aG plugdev $LOGNAME (or equivalent for your OS)
the rules.d file in etc/udev needs to be edited (if its not already) to include: SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0664", GROUP="plugdev"
then: chmod 644 51-android.rules
and: chown root: 51-android.rules

Thank you for the replies.
I tried to use adb/fastboot on a Win7 desktop after I posted the above, and I cannot get the phone and win7 to see each other at all.
I have since tried to get into recovery mode but get "No Command".
What can I do to move forward? Phone boots and works fine once I get out of recovery.
This phone is fresh from Google, never had a sim in it.

Thank you for the detailed answer. I am having difficulty implementing the mods you listed. I have been a Linux user on and off for several years but I do not have deep knowledge of the inner workings.

After factory reset, stepped through process again, but still no joy on Linux (Certainly still the above mentioned group permissions issue which I failed to figure out how to fix).
Win7 did not seem to be working for a long time (got no popup on phone asking for debugging authorization), after a half hour of attempts I walked away for 15+ minutes and when I looked back at the phone the Debug auth popup was finally there...
Booted to fastboot, did $ fastboot flashing unlock <= Returned: "Finished. Total time: 0.356s" LOL, yeah, with me struggling since yesterday...
Now fastboot screen says Device status: Unlocked

Windows has to update. The 30 minutes was probably the update in the background. My windows 10 did the same thing. Linux doesnt work anymore. I used ubuntu with latest adb and fastboot packages. Manually installed newest tools zip. Nothing. I got it to work a few times. Windows 10 is a little buggy too. Only fastboot I found to work on the pixel 3 xl without and or little errors was my MacBook. Which I have dual booted to chromeos and Ubuntu in chromeos. Also restarting on windows anything puts it into the loop of things. You can install adb and fastboot on windows but they need a restart to work. Unless just mounting the file folder and using it that way.

I am still trying to get adb/fastboot to work on my Linux Mint 19.1 laptop so that I don't have to rely on an old Win7 machine to sideload monthly updates. I have been a Linux user on and off for several years, but I have no deep knowledge of what goes on 'under the hood'...
Can anyone here with a deeper knowledge of Linux and/or Mint 19 help me implement the mods that uicnren outlined, or otherwise help me get adb/fastboot to work?

I realize this is a bit old now, but, in case it's helpful for someone in the future...
Often the /etc/used/rules.d directory is empty. You just need to add the file 51-android.rules into that directory.
Code:
sudo touch /etc/used/rules.d/51-android.rules
You need to run that command as root which is why it's prefaced with sudo.
Then you can edit the file as described in the first post. As stated earlier, much better to type into your editor rather than cut and paste because you want to make sure no weird html characters get introduced.
