Hi everyone,
I have looked everywhere on google and have been at this for over 5 hours now. I have tried rooting my phone from 3 different PCs (XP SP3, SP2 and 7). With all of them i have managed to get the drivers for adb installed (after many problems) and got all the way to the fastboot part of the rooting.
Once i get there, i have the same problem on all 3 PCs. ADB can no longer find my phone! Following the instructions, i checked for the device before i powered it off and found it by doing abd devices in cmd prompt. The moment the device is powered off and then back on, bam! No more device!
I am at my wits end at this point and just don't know what else I could possibly do! I would be immensely grateful for ANY advice.
I did check that my device allowed USB debug so that's not it either.
Also, my phone is a Rogers phone and I have just put through the upgrade they sent this morning.
adb cant find your phone in fastboot mode but fastboot can
Try writing fastboot devices instead of adb devices
All the comands in fastboot mode start with fastboot...e.g fastboot flash xxx xxx.img
I ran into this problem as well on my attempt, I forgot to re-enable (or enable) depending on where I was at "usb debugging" which is in:
settings> applications > development > check the usb debugging box.
After that, when you do abd devices in your shell, it should surely list after that. Good luck!
edit-- woops scratch that.. sorry I just read back that you made sure of that.
Thank you for that!
Now, i see it in fastboot, but when i try typing fastboot boot recovery.img i get a "cannot load recovery.img"
Sorry, apparently i need a lot more hand holding than i though!
(this is where I am getting the instructions from HowardForums. I'd post the link but I can't do that yet on this forum...
Basically, these are the instructions i am following:
If the phone you have is an HTC Magic (no hardware keyboard), the method is pretty much the same. I modified Haykuro's zip with files that were meant for the Magic. You can grab it here:
*link*
Again, open another command prompt as steps 2, and 6-8 are entered in the command prompt.

3. apply update. (LET IT FINISH, DO NOT TOUCH ANYTHING UNTIL YOUR PHONE IS COMPLETELY IDLE. DO NOT TOUCH AFTER FIRST REBOOT (WHEN CHIP APPEARS) UNLESS YOU LIKE A BRICK. )
4. reboot out of recovery mode.
5. power off phone, hold back button and power to boot into fastboot again
6. fastboot flash boot boot.img
7. fastboot flash recovery recovery.img
8. fastboot reboot
enjoy!
These are pretty much the Haykuro instructions for the Dream, which I modified to apply to the Magic. The boot and recovery images were made by Amon_RA. Happy Rooting!
Just like with the Dream, the first part flashes a good SPL, the second flashes a rooted boot and recovery. The easiest way to test if the device is rooted is to open another command prompt in the tools dir and type
Code:
adb root
If it returns that adb is already running in root, then you're all set.

Am i doing something wrong?
Thanks so much!
You need to navigate to the folder where you saved your recovery.img
For example if you put it on d:/Android dev. you will need to do (inside cmd)
d: (switches to drive d
cd d:/Android dev. (changes the folder to android dev.)
and then issue the fastboot command
without the brackets of course...

Again, thank you so much! It seems I am still having issues as now I'm being told that "remote not allow".... is this a rogers thing?
Again i do apologize for all the hand-holding necessary here
yes, i am getting this <remote:not allow> message too. I was able to fix my other magic (purchased in october) via fastboot boot recovery.img but not this new one i have (purchased in Dec).
Anyone have any ideas how to bypass this block of 'remote, not allowed"?
Hi! I was trying to backup my Orange Monte Carlo following a Portuguese tutorial but I'm stuck in the middle and I've got no help! Hope you can provide some! These are the steps I followed (translated)
1 - Install ADB Made Easy;
2 - Open cmd;
3 - Activate cellphone debug mode;
4 - Connect via usb (without mass storage) and install drivers if request [it was requested and i installed];
5 - Run adb devices, it should show your device [it did];
6 - Run adb reboot bootloader, your cellphone will boot in Fastboot, wich is an Android image without menus [correct until here];
7 - Run fastboot devices, your device yor a question mark(?) should show up (advance to next step), else you miss drivers [step not completed];
cmd says 'fastboot' is not recognized as a command. Now my phone is stuck connected to the computer with an adriod pick and I have no clue on what to do next!
Don't know where you were going with this but to reboot your phone just pull the battery ..
Not bricked

Thank you! Do you have any idea why the last command doesn't work? I believe it has something to do with file location... I'm trying to backup my Monte Carlo. Next steps were to "fastboot boot recovery.img" and then backup.
It should be in the platform-tools directory of the android-sdk. Verify that it's there...if so cd to that directory and it should work
I already fixed it for myself, thanks! Now I can't seem to be able to install clockwork!
Doing <<fastboot boot "C:\Users\R&J\Downloads\recovery.img">> reboots the device but doesn't enter recovery.
Doing <<fastboot flash recovery "C:\Users\R&J\Downloads\recovery.img">> , <<fastboot reboot>> and <<adb wait-for-device reboot recovery>> results the phone entering android's default recovery (no acess to backup feature).
Any way to help? Thank you!
The first command <<fastboot flash recovery "C:\Users\R&J\Downloads\recovery.img">> is trying to write the recovery.img you downloaded to a recovery partition on your device. It may not be overwriting the original recovery.
try changing permissions by doing
adb shell
su
chmod 777 /recovery
then try to flash again
Lol it seems like I have been luck enough to solve my own problems, I have sucessfully installed ClockworkMod Recovery 4.0.1.4 unofficial MoDaCo Edition using a bat file . Now I can't seem to find a way to flash recovery back to stock. I though this was an option inside the modded recovery. Any tips? Thanks again!
EDIT: I have the stock recovery file . God... this tutorials I'm folowing aren't that noob friendly...
A lot of people have been asking, so here are my notes for gaining root w/o flashing or unlocking the boot loader. :good:
Thanks to Chromium and The Jack of Clubs for their initial concepts and documentation.
Download ADB and set up Tools
Download the full Android SDK here:
http://developer.android.com/sdk/index.html#download
(scroll to the bottom of the page -> DOWNLOAD FOR OTHER PLATFORMS -> SDK Tools Only)
Extract the android-sdk-windows zip to c:\android-sdk
Browse to C:\android-sdk\android-sdk-windows\
Double Click and run SDK Manager.exe
Uncheck everything except the Android SDK Tools and Android SDK Platform-tools
Hit the Install xx Packages button
Download Super SU and TWRP
Download the latest TWRP here:
http://techerrata.com/browse/twrp2/bacon
Extract the TWRP image file and save it as recovery.img in the following folder:
C:\android-sdk\android-sdk-windows\platform-tools
Download SuperSU here: http://download.chainfire.eu/452/SuperSU/UPDATE-SuperSU-v2.02.zip
Plug your phone into your computer and Copy SU zip to the phone... (anywhere will work)
Get your Phone into Fastboot
Reboot the phone in fastboot mode (hold volume up + power). You should get a cyanogen guy smiling at you, this indicates the phone is in fastboot mode.
Open a command prompt and do:
cd C:\android-sdk\android-sdk-windows\platform-tools
Type:
fastboot devices
NOTE: You should receive a list of connected devices, this means your PC is connected to your phone. If not, something is wrong with ADB or your USB driver and you need to fix it before you can proceed!
Boot with TWRP and Flash
If “fastboot devices” worked without error, type this:
fastboot boot recovery.img
After the recovery.img transfers, your phone reboots into TWRP. Hit “Install” and choose the SuperSU.zip from the location on your phone that you saved it to earlier.
Once flashing is done, reboot and enjoy root. No re-imaging or unlocking your bootloader necessary.

if you dont want to wipe data, it also sets flags a tamper bit (which can now be reset), or if you just plain dont want to.

Ah ok, i did unlock and switch to PA after second boot , so there were no data that would be lost
May I ad that there is an easier way to get adb. Its a program called minimal adb. This what I used originally in case someone prefers to just download that file. Just an option thats all... :good:
Nice tutorial
Download
Search for TWRP recovery for LG V10 H901 (File: twrp-2.8.7.0-h901.img (31.7 MB))
Backup Apps and Data
While this process should not wipe any of your data, a backup is highly recommended. Once you install a custom recovery like TWRP, make sure you backup your system, data,etc. from the recovery. It will be helpful in case anything goes wrong.
Prerequisites
This guide is compatible with LG V10 H901 only. Do not try it on any other devices or variants.
Unlocked bootloader is required to install a custom recovery like TWRP on your device. Click here.
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
Install Motorola USB Drivers on your computer.
Open Settings> Developer options and enable USB Debugging on your device.
Go to Developer options and enable Allow oem unlock.
How to Install TWRP Recovery on LG V10 H901
Download the recovery image file. Extract if in case a zip file. Now transfer the file to your PC where you can easily locate it.
Make sure you have setup ADB and fastboot on your PC. Also accept Always allow from this computer when you plug in the device for first time to enable USB Debugging.
Now power off your device and unplug it from your PC.
Boot into the bootloader or fastboot mode. To do so, press and hold volume down and the power button simultaneously for 5-6 seconds. When you see the bootloader screen, connect your device to the PC using a USB cable.(Choose fasboot if option is available) Alternatively, you can also issue the following command through your cmd or terminal, while connected to the PC in order to boot into the bootloader.
"adb reboot bootloader"
Navigate to the location where you have placed the recovery file. Rename the recovery file to a simple one, like recovery.img. While the folder with recovery.img file is open, hold shift key on keyboard and right-click on an empty space and select “Open command window here” option to launch a cmd window.
Now issue the following command in the command prompt to check your device connectivity
"fastboot devices"
Now flash custom recovery. Issue the following command for that.
"fastboot flash recovery recovery.img"
Custom recovery will now be installed on your device. Now boot your phone in recovery mode. You can do this by turning your device off and then press and hold volume down and power keys at the same time. Or you can simply enter the following command.
"fastboot boot recovery.img"
Once into the recovery, you can backup your current ROM, data, EFS and more.
Once you have installed TWRP, you are all set to install custom packages onto the device’s system. Alternatively, while on Linux or Mac OS, you can issue “./fastboot flash recovery recovery.img” command to flash the TWRP recovery.
Root
As you already have TWRP, simply flash the SuperSU file (version 2.56) to gain root access
@TheJesus @KAsp3rd, thanks guys for everything you've done over the past few days. no shade to @joe01gun but if people are going to use these instructions make sure you search the rest of the forum for what thejesus and kasp3rd put together to get us to this point - definitely appreciated. thanks @joe01gun for putting these additional instructions together.
Your post says the following:
Set up ADB and Fastboot on your computer. You can download the minimal ADB and fastboot tool from here (unzip it) or get the quick ADB and fastboot installer from here.
yet, there's no link to the necessary files to "unzip" them. Any suggestions?
Thank you for the help, but where do we get fastboot set up on our PCs? Yes, this is getting confusing with the steps outlined above. I followed the first step and had to take out the battery because I was stuck in fastboot screen with small tiny text in the top left that didn't respond to any manipulation with the volume keys on the back of the device and wouldn't restart any way until I took out the battery.

I think it's cause he's not allowed to post links yet cause he's too new. I followed this guide http://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930
You can get twrp from the development forum.

Your condensed thread is more convoluted than the actual development thread which also includes the links to everything.
I'm still wondering why you have install Motorola USB drivers for an LG phone..
Understood
Understood
The one on development is straightforward and I managed to make it done.
If you don't lock the bootloader back, you will see bootloader unlocked when starting up.
If you have root enabled file explorer, you should remove /system/priv-app/adaptclient folder to avoid annoying root request from adapt.
Please use the main dev thread for instructions on what to do, found below. Having duplicates for what is essentially the same thing can cause confusion and just takes up unnecessary space. So I have closed the thread.

TWRP 3.0.2 for Acer Predator 8 ported by Ruben. - If you like my work please donate here, it will also give me a boost to make more things for this device : https://www.paypal.me/RubenCraveiro
----------- -----------
IMPORTANT NOTE ABOUT ROOTING AND UNLOCKING BOOTLOADER:
After flashing TWRP 3.0.2, use the SuperSU 2.46 flashable zip, do NOT use latest version or will result in a bootloop. Good Luck and have fun with rooting. Unlocking bootloader will delete all your data, so please make a backup first. Thank you.
----------- -----------
CREDITS
And also, before anything i would like to say thanks to @arjaylzo for telling me the name of a device with TWRP which helped making this update possible.
REQUIREMENTS
1- Fastboot/ADB Drivers and ADB folder
For drivers: http://adbdriver.com - Download ADB Driver Installer (universal) from the website, extract it, connect device it should detect device(if not, enable USB Debugging and reconnect), and press install, it should install drivers.
For ADB Folder: download this and extract to your main drive(C:/): https://goo.gl/ZTrfBb
2- Unlocked Bootloader (you need requirement 1 to do this)
Instructions for Unlocking bootloader: Go on settings, about device, press build version several times till it says your a developer, go back to settings, press Developer Options, and enable OEM Unlocking. Power off, then press at same time Power and Vol+ button, then connect to pc and open a cmd and write cd c:\\adb and write fastboot oem unlock, then accept the prompt it will give on tablet, and follow the rest of the steps.
----------- -----------
New TWRP bugfix update! Now you can flash stock rom on TWRP without bricking! Download Page updated!
----------- -----------
BUGS:
1- adb shell command needs to be sent before system partition is mounted or it will give an error, after doing adb shell you can mount system and do all the modifications you need.
2- You cant flash any img on twrp it gives an error, im trying to fix.
3- Backups do work, but everytime twrp restarts, the device name seems to change (which means that on /TWRP/BACKUPS/devicename/backupsinside/ changes every reboot so you have to go get the backup inside the old devicename folder and put on the new devicename folder).
----------- ADITIONAL NOTES -----------
Im leaving an unsecured boot image because system seems not want to boot android if anything seems changed. So please if system does not boot after flashing twrp/rooting, flash the unsecured boot img on fastboot
----------- -----------
Steps TO INSTALL TWRP AND ROOT
1. Download and extract the files: https://drive.google.com/file/d/0BxzG5iupOOSKNTdlRC1Wd0VmTlk/view?usp=drivesdk
2. Power off the tablet.
3. Enter fastboot mode by pressing the power button while holding down Vol -
4. Open up command prompt and navigate to the directory where fastboot.exe is located.

make sure you didnt put a folder inside the adb folder instead of the actual file and make sure your writing the right name of the file..

If you flash stock rom, i think you have to reinstall stock recovery, the rom itself already brings stock boot.. after flashing stock recovery it should boot since no modifications have happend

On step 4 You need the fastboot files, (adb & fastboot) just search how to install adb and fastboot drivers, choose the directory where to install them and place the needed files inside that folder and open a command prompt on that folder so you can flash the files.

That means adb drivers arent corrently installed, but i can see you have the folder with adb, all you have to now is download this(drivers): http://dl.adbdriver.com/upload/adbdriver.zip
Extract and open the software eith the tablet plugged in, it should tell of drivers is installer properly or not, and if not you can install, after installing it should work on the cmd the commands..
