This was tested on Telstra's XT925 (Razr HD) on Jelly Bean 4.1.2
You will need a copy of fastboot which is part of the Android SDK.
I know there is a touch of double posting here but I wanted to make a thread so users can find all the info they need in one place.
I found the Telstra XT925 particularly tricky to work with and the below method worked flawlessly where others failed.
Give it a try and let me know how you go.
Thanks all.
Apologies as a new poster I can't supply the links, but most of you will know where to look.
Files Needed:
CWM-SuperSU-v0.99.zip
cwmrecovery6028-xt925_20130219-epinter.img
Motorola drivers from website.
(1) While the phone is fully loaded, go to Settings -> Developer's options and enable "USB Debugging".
(2) Now power off the phone completely
(i) Either by holding the power button for 5-10 seconds or pressing it once and hitting "power off"
(3) Once powered off, hold the power button + both volume buttons at the same time for 3 seconds
(4) You'll see a bootloader menu, you have literally only 3 seconds to select an option
(5) Using the volume buttons +/- go to select "AP Fastboot" then press the middle "rocker" button that's nest right inbetween the volume
button to select it.
(6) If successful, you'll be taken to fastboot screen with white writing on a black background.
(7) Install the Motorola USB drivers (these are readily available from the Motorola website)
(8) Install the Android SDK
(9) Download the Clockworkmod recovery image
(10) Download the Clockwordmod Super User zip
(11) Once the USB drivers are install, plug your phone in, it should detected as a ADB device.
(12) Copy the CWM image into the folder where fastboot is located in the SDK (normally \Android SDK\sdk\platform-tools
(13) Open up command prompt as administrator
(14) Change to the SDK platform tools folder where both fastboot and the CWM recover image is kept.
(15) type in "fastboot flash recovery FILENAMEHERE.IMG"
(16) Wait a few seconds, confirmed successful
(17) While the phone is still on, you can copy over the Super User zip file onto the SDCARD on your phone.
(18) Power off phone.
(19) Repeat the power + volume buttons process but then this time select "Recovery" and press the rocker.
(20) This should load into the Clockworkmod recovery system, go to install zip. Then select the SU zip file.
(21) Install, then reboot.
(22) Let phone boot up, you should now have root access.
You forgot to mention the need for an unlocked bootloader to use this method

Yes sorry forgot to mention that thanks. Can't always get the first post right Otherwise thankfully Motorola makes it easy to do the initial bootloader unlock anyway...at of course, the cost of your warranty.
more clarification
hi sorry for a noob question but how to confirm that the boot loader is unlocked??, i am on telstra with Razr HD on JB (JB was done via OTA update). I tired the other mechanism of using the Razr Hd utility 1.10 and did not work
Are you able to show screenshots or do you have a video tutorial......
PS: my understanding is that on Telstra when in fastboot the screen shows "Locked" for all razr HD devices so how did you manage to unlock the boot loader
thanks that works fine even on french ROMs
sorry to ask here,
I flashed cmn on moto xt925 ul boot loader FIDO 4.1.2, but how in the hell i chose install Su from zip??? i was able to enter into recovery, scroll down to install from zip but how to select that option? hit power nada? is there a key combo
Finally got it, rooted at least what a *****y moto haha

FIRST AND FOREMOST: DISCLAIMER,
I am not responsible for any steps your take in modifying or following the steps described below. This is simply a guide to assist you with restoring your phone. If your break, drop, ruin, brick, wipe, slap, chop, honk, ding, open, slave or unock your phone and it does not respond how you expected sorry your phone, your responsibility.
What is described below worked for me.
Ok, after searching for hours or nearly days for a way to unroot and get back tot he stock rom that allows for Over the Air Updates (OTA's) I finally figured it out after piecing together tons of threads on related subjects.
Anyway here it is...
On my nexus one I was using a CyanogenMod Rom and wanted to revert back to stock because of a few glitches I didn't like. I was presented with tons of problems when trying to do so. This is what I did.
For dummies version:
GET THE NECESSARIES
(1) Downloaded the stock ROM FRG83 from Modaco HERE
(2) Unzipped this to a folder I created on my PC (I named it Platform-Tools)
(3) Downloaded and Installed the Android SDK. This comes with ADB and driver for your phone which is a must need. HERE
(4) Copied all files from the android/android-sdk/platform-tools folder to the folder I created earlier in step 2.
(5) Downloaded fastboot command (Available in attachment below)
(6) Downloaded flash_image.zip (Available in attachment below) (Optional - flash_image.zip only needed if using ADB method and is not described below or recommended)
UNLOCK BOOT LOADER
(1) Unlock Boot Loader (Yeah you have to do it). If not done you will get an error saying unable to verify signature when trying to load the img files.
-Boot in to boot loader by Powering on your phone while holding down the trackball
-Connect phone to your pc using a usb data cable
-on the boot screen it should say something like "fastboot usb" after doing so
-Type fastboot oem unlock
-Read the warning and accept it
(2) Boot in to boot loader by Powering on your phone while holding down the trackball
(3) Should say unlocked at the top
PHONE UNLOCKED AND READY TO FLASH YOUR PHONE TO STOCK
(1) If not done already Boot in to boot loader by Powering on your phone while holding down the trackball
(2) Connect phone to your PC with a USB Data Cable
(3) From your PC command prompt change directory to where you save your img files and the fastboot command stuff
(4) Type The Following In Sequence from your PC Command prompt:
fastboot flash boot (YOUR DIRECTORY)\boot.img
fastboot flash recovery (YOUR DIRECTORY)\recovery.img
(5) Boot in to recovery
-Select bootloader from the menu
-Select recovery from the next menu
(Wait, a triange with an exclamation mark appears)
-Press the power button along with the up volume button
(Boots to the android recovery menu)
-Wipe everything
(6) Reboot in to the boot loader and Type The Following from your PC command prompt In Sequence
fastboot flash radio (YOUR DIRECTORY)\radio.img
fastboot flash system (YOUR DIRECTORY)\system.img
When done reboot and enjoy your fully restored un-rooted back to stock nexus one and enjoy all your OTA Updates as they are released.
If there is something I missed or needs correction let me know and I will make necessary revisions.
pardon my ignorance but i was under the understanding that the Nexus One already ran Stock android

Anybody that needs to download and flash an Original ROM obviously didn't follow the first rule of flashing. NANDROID BACKUP YOUR STOCK ROM FIRST!!!
To return to stock for OTA updates all you need to do is restore your Nandroid backup and reboot once. That's all.
Hi all,
I have recently got hold of a Desire S and updated it a couple of months ago with the standard ota update from O2 (Or branded phone)...since then I have been getting signal errors which I have read about elsewhere.
Anyway thought I would root my phone...I S-off using revolutionary, it did not appear to work the first time, it appeared to s-off the phone but I did not get prompted for the CWM download, second attempt, it informed i was s-off and to download the CWM, I clicked yes and it tried to download but nothing happens.
So as far as I can tell I am s-off but no root. I have tried gingerbreak and superoneclick both of which stall during the process and do not root my phone.
I am very new to this and not sure where to go from here to get my phone rooted.
My Hboot was 98.002 now it shows:
-Revolutionary-
Saga PVT Ship S-off RL
Hboot-6 .98.1002
If I go into recovery I just get a red triangle with an ! and have to reboot the phone.
So I am at a point where I do not know what to do to get it rooted....or can I just get a pre rooted rom and flash that over the top?
Thanks
I'd suggest that to start you change these setting on your phone
Settings->Power->Fastboot = OFF
Settings->Applications->Development->USB debugging = ON
There are various links in my signature, they should all help. Download the adb&fastboot link and extract the files to your c:\temp\ directory on your PC. Then install the HTC drivers then continue and follow the instructions below:
You first need to download CWM recovery image file for this device to your PC into again the C:\temp directory.
Put the phone in Fastboot USB mode (by following instructions below
Unplug USB
Turn the device off
Hold volume down button (HOLD IT) and press power
Hboot will start.
Wait for sdcard scan to complete.
Plug in USB cord connected to the computer
Press power ONCE and Fastboot USB mode starts
Then run a CMD shell from the PC and then issue the commands into it from the directory where you have put the downloaded img file (c:\temp\)
fastboot flash recovery cwm-4.0.1.4-saga.img
adb reboot recovery
To root you phone then
Download and then copy su-3.0-efgh-signed.zip to your sdcard root
Start clockworkmod recovery
Unplug USB
Turn the device off
Hold volume down button (HOLD IT) and press power
Hboot will start.
Navigate to recovery with the vol down button.
Press power to select and enter recovery.
Select "install zip from sdcard"
Then select "Choose zip from sdcard"
Then select "su-3.0-efgh-signed.zip"
Then select "Yes - install su-3.0-efgh-signed.zip" to confirm
Then go back
Then reboot.
Try to download the pg88img file of cwm our 4ext you find them in the index thread.
Put the pg88img in root of your sd, reboot to bootloader and flash the file. After this the easiest way to gain root would be to flash an prerooted ROM.
Don't forget to make a backup of you're current ROM if anything fails
Swyped from my Desire S
I feel your pain. I am replying to you to make sure you did all the steps required. Furthermore, in using "Superoneclick", which worked for me on my Samsung Fascinate, if I missed a step it didn't work. I.E - I didn 't re-boot!
@ben_pyett you sir are a lengend!!!
what you posted worked...the only slight thing I had to do different was install the htcdrivers first, as it would recognise my phone, then I could do the adb reboot recovery.
It said it failed but I continued to flash su-3.0-efgh-signed.zip and happy days, now to load up a rom!!
many thanks and also to those who replied

Glad to have been able to help.
Now take a backup using CWM so that you have a safe fall back position - just in case!
I'd then suggest updating the recovery to 4EXT which I personally find easier to use.
You'll then find all the ROMS linked within the INDEX thread
Enjoy!
just running a backup now....just waiting for it to finish then to hunt for a rom.
Will probably use rom manger and voidru, seems a popular choice and a good place to start.
Then pay the £1.56 for 4ext
Thanks again

Completely agree with you. Just wanted to point that it is not necessary to pay (thanks to madmaxx82)
Yeah, I just rooted my galaxy tab, installed lagfix etc (feels like a new piece of hardware now, it so fast!)
I first coudnt do it, because i didn't have the Samsung drivers installed (just like the HTC drivers here)
I never actually rooted my desire s manually!.
I just s-offed, then installed custom roms straight away which already come pre-rooted.

Swyped from my Desire S using XDA Premium
Hey guys.
Basically:
My brother has a Motorola Xoom 32GB MZ604. He tried to root it but it was unsuccessful. After reboot of the failed root, it will now get stuck on the M boot screen and not move, there's no loop as such, it will literally stay on until it runs out of battery or is turned off by pressing buttons.
Any ideas what's happened and how we can fix it?
He took it back and they want £46 to put new software on.
Thanks
Oli
Can you still enter recovery??
Sent from my Xoom using XDA Premium App
I believe he can but he said he's already wiped it? I'll try again though when he gets home tonight from work.
I had the same issue when I first tried to root my xoom. Here is what you do:
1) take out the external sd card. And thru pc , put on it the new recovery image and put it back into xoom.
2) search my posts on how to root mz601. I know yours is mz604. But it is the same procedure. I will post steps for you soon.
Sent from my MZ601 using Tapatalk 2
There you go. Step by step.
First, download the below and put them onto your xoom internal and external SD card. Put them under /mnt/sdcard for internal sd, and under the root of your external sd card.
To download:
• Get the Motorola USB drivers to your laptop: http://developer.motorola.com/docstools/USB_Drivers/
• Get the Android SDK to your laptop: http://developer.android.com/sdk/index.html
• Recovery Image: http://goo.im/devs/teameos/recoverie...ecovery-r6.img
• GAPPS: http://goo.im/gapps, your GAPPs would be: gapps-ics-20120429-signed.zip
• ROM: get the latest release for mz604 from here. http://goo.im/devs/teameos/roms/nightlies/wingray/
Steps:
1. Power off your XOOM device.
2. Press and hold the volume down button while pressing the power button at the same time. Note: Even if your xoom starts again, just keep the button pressed until you see "Starting fastboot protocol" on the screen.
3. Connect Xoom to your computer via USB.
4. Open a ‘Command Prompt’ or ‘Terminal’ window on your computer in your sdk/tools folder. This is the sdk you downloaded above.
5. unlock your xoom and flash the recovery image. The recovery image should be in your current working directory where you have command line navigated to: Type:
adb reboot bootloader
fastboot oem unlock
fastboot flash recovery eos-recovery-r6.img
fastboot reboot adb
reboot recovery
Now, you have your device unlocked and recovery installed.
Reboot your xoom by selecting the option "reboot system now" from recovery. you can navigate up and down using the volume buttons. Once an option is highlighted, press the power button to select, you will still have your old ROM.
To flash the other ROM downloaded above,
1. Boot into recovery by:
i. As soon as you hit the reboot command above, you should see a Motorola logo appear. Wait 3 seconds and tap the Volume down button and the words Android Recovery should appear on the screen. When you see that, tap the Volume up button and you’ll boot into recovery.
2. From within Recovery, perform wipe data, wipe cache, and go to advanced, wipe dalvik cache and battery stats. Don't worry, if the ROM and GAPPs are deleted, which should not be the case, you will have them on your external sd card
Note: wipe data will delete your stuff on the xoom. It would be great if you backup your files that you need to your external sd card before you start any of this procedure.
3. In recovery, navigate to install zip from sdcard > choose zip from sd card and select the EOS ROM you copied to the root of the SD card. Once the files are flashed, DO NOT reboot afterwards. Hold on.
4. Again, from Recovery, choose install zip from sdcard > choose zip from sd card and select the GAPPs you copied to the root of the SD card.
Then hit reboot system now. It will take 2 - 3 minutes for the first reboot. Setup your google account. and you are good to go.
Later reboots will be much faster (around 40 - 50 seconds).

if it's getting to the splash screen then just as you turn it on, whack it into fastboot then you'll be able to flash new recovery or flash back to stock.

Go here: http://developer.motorola.com/products/software/ to get the stock images to flash in fastboot to get the xoom back to factory conditions. It's normally the last resort, but the most successful. You may need to sign up for an account, but it is free.
Right guys basically i want my xoom to be complete stock what is the best way to do this. can i still use the above steps but by using the default motorola software.. it looked like it was using differnt firmware, and one of the links didnt work. sorry i really dont have a clue what to do and need my xoom back its been away for 3 weeks now
yes you can.. just flash the stock OS for it and you are good to go again.
and whats the best way to do this. sorry im not too sure about rooting on the xooms etc i used that poxy one click root which by the looks of things lots of people have had problems with it.
Rooting is pretty straight forward steps. Use the steps I provided you above if you want. If you are looking to flash stock rom, you still need recovery and stock rom to be flashed.

My mz601 is stuck at booting it keeps going off and booting again
My steps to a factory reset Xoom Wingray
My Xoom Wingray also crashed and was stuck in the boot animation. I still use my Xoom as my alarm clock and music player with multimedia dock. I had to put the Xoom in the drawer as there was no way to turn it off, it would just reboot back to the flashing animation. I was surprised that it wasn't dead by morning and it was still in the boot loop. So I wanted to revert back to the stock ROMs so this is what I just did. This is assuming you have nothing installed on your PC so from scratch. I actually just went through this a hour ago so I am still in the very last step.
First download and install the following:
-Minimal Android SDK from http://forum.xda-developers.com/showthread.php?t=2317790
-Motorola drivers from http://www.motorola.com/Support/US-...tware_and_Drivers/USB-and-PC-Charging-Drivers
Now you need the original images:
You can try to get it from the source here, https://motorola-global-portal.custhelp.com/app/standalone/rom-images , but I had to request access to the files and was impatient.
I found the original images here instead, http://forum.xda-developers.com/showpost.php?p=64412362&postcount=10
You will need to find the original images for your device, the source in the first link should be able to help you.
Flashing Instructions
I would recommend having the power cord attached throughout this, but if your Xoom is fully charged it should be ok.
Assuming you installed the minimal SDK in the default folder, C:\Program Files (x86)\ Minimal ADB and Fastboot, unzip the individual images (boot.img, recovery.img, system.img and userdata.img) into this folder. If you installed into some other folder unzip there instead.
Now you need to put the Xoom into fastboot mode. Press the VOL-UP and Power to reboot, but then keep holding the VOL-UP. You should end up in fastboot mode.
Plug the Xoom into your PC.
Open a CMD window into the fastboot directory. If you installed the Minimal Fastboot from above you can simply go Start>Minimal ADB and Fastboot>Minimal ADB and Fastboot.
Type "fastboot devices"
Type "fastboot flash boot boot.img"
Type "fastboot flash system system.img"
Type "fastboot flash recovery recovery.img"
Type "fastboot flash userdata userdata.img"
Type "fastboot erase cache"
Type "fastboot oem lock"
You can see the responses I got in the attached image. Once complete the Xoom rebooted with the original Honeycomb OS and then I had to wait for all of the OTA updates to be pushed. This has taken several hours and now it is updating all of the stock Google apps.
Help with my MZ601
Please, I need help with my MZ601.
A friend who recently passed willed his MZ601 GSM/Wifi to me. I do not know a thing about it; however, I have read a couple of posts. I gathered from these posts that the MZ601 would need to be flashed with a new ROM, especially as when I powered it on, it stopped at the big 'M' logo.
I have checked so many posts online here and found links to many Roms and Gapps, but none is working.
Please, I would be glad if anyone could help me with the following:
(a) MZ601 GSM/Wifi ROM - whether Stock or Custom ROM.
(b) Also remember that I am a idiot; hence, I will need a step-by-step guide on what to do.
Thank you very much.

Rooted when I first got the tablet, was not using it much. Used Kingoo to remove root. On reboot it is now stuck at the NVidia logo.
When I reboot into recovery mode and select factory reset I get a CWM manager screen, select factory reset and reboot. Still stuck on the NVidia logo (currently in excess of 30 minutes.)
Any ideas?
Solved it:
Solution:
1. Register for the NVidia Developer program (I chose the gaming selection, not hardware). Takes about 30 seconds: https://developer.nvidia.com/gameworks-registered-developer-program
2. Download & unzip the Shield Software: https://developer.nvidia.com/gameworksdownload
NOTE: Make sure you download the correct version for your Tablet. WIFI, LTE-USE or LET-RoW (Rest of World). DO NOT FLASH THE WRONG ONE.
3. Download the Minimal Fastboot and ADB http://forum.xda-developers.com/showthread.php?t=2317790
4. Install the drivers for the shield from the NV download in step 2. The one PDF in the download is instructions (ish) if you need them.
5. Run the Minimal Fastboot and ADB installer.
6. Copy the contents of the fastboot folder to the NV folder from Step 2 (this is easier than editing the path for a single use).
7. Power off the tablet and connect it via USB to your computer
8. Hold down the Volume Down button for 3 seconds, press the power button and continue holding the volume down.
9. At the recovery screen you will see a menu. Look carefully. The bootloader will need to be unlocked. If it is locked see the note below. Select fastboot and press power. (I am not sure this step is required, since it returned me to the same menu, but it worked)
10. from the NV folder in step 2, double click "flash-all.bat" to flash the tablet.
If this did not work I would imagine that your boot loader is locked.
NOTE: To unlock the bootloader (Instructions are from NVidia directly)
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.
The complete instructions from NVidia (may be easier for some)
SHIELD TABLET RECOVERY IMAGE FLASHING INSTRUCTIONS
To follow the instructions in this guide, you will need adb and fastboot.
These tools are provided as part of the Android SDK:
http://developer.android.com/sdk/index.html
Before flashing this recovery image to your SHIELD TABLET, connect your SHIELD TABLET
via USB to the PC where you downloaded this recovery image.
Next, put your SHIELD TABLET into fastboot mode using one of the following methods:
SW method:
- Boot to android home screen
- Connect the device to linux/windows system
- Open terminal (on linux); command prompt (on windows).
- Type "adb reboot bootloader" in terminal/command prompt
HW method:
- Turn off the device
- Press "Volume Down" -> "Power", hold "Volume Down" and leave Power buttons till device boots
To flash this recovery image to your SHIELD TABLET, run the following commands from
the directory where you extracted the recovery image package. If this is the
first time you have done this procedure, you must unlock the bootloader (see
below):
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb
Quick resolvement! Nobody could comment in the meantime.

For a stock K1 (no custom recovery TWRP, etc.) I'd say the process outlined above is your best bet (restore stock recovery image).
I don't think you have to register to the Nvidia Developer Program anymore. Just go to the NVIDIA Download Center (as linked in the post above), find the right image, and download. Use search term "K1" and you should see the right image as one of the top few results. I believe version 5.2.0 is the last one that was released.
Once downloaded, flash the partitions using fastboot, as noted in the instructions.
First, you’ll need ADB and fastboot, which can be downloaded here. To set up ADB, go to Settings/About Phone/Software Info and tap on build number until you get a toast notification saying “You are now a developer!” You will now have a new category in Settings called Developer Options. Go into developer options and enable USB debugging and OEM Unlock. You won't be able to turn it on if your phone is plugged in to your PC. Once you've turned it on, go to your PC, open Terminal or Command Prompt and type “adb devices”. Then plug in your phone and hit enter. You'll get a prompt on your phone to “Allow connections to this PC?”. Check Always allow and Allow. Now run “adb devices” again. Your device should now appear in Terminal.
If you have a SD card, download the latest zips from here and here onto your SD card. It'll save you a step later on.
Then you'll need to reboot to fastboot by holding down VOL- and plugging in USB while power is off. Alternatively, you can type “adb reboot bootloader” in Terminal or Command Prompt.
Next, you'll need to unlock the bootloader. Bootloader unlocking will factory reset your phone! Once you're in fastboot, run “fastboot oem unlock” in Terminal or Command Prompt. Now the bootloader is unlocked.
Now it's time to flash TWRP, a custom recovery for Android. It's going to be the way you install custom ROMs and add-ons. Download Official TWRP here. Once you've extracted the recovery.zip, run this command: “fastboot flash recovery path/to/recovery.img”. Once the file has flashed, disconnect the USB cable and battery. The next step is important! You're going to need to boot into TWRP for the first time. With the phone off, hold down VOL- and press power until the phone vibrates and the LG logo appears. While still holding down VOL-, release and immediately press and hold power. You should now be at a white screen that says “Reset all data and restore to factory settings?” Use the volume and power keys to select yes and yes again. If you've installed TWRP successfully, it won't actually factory reset your phone. Now you should see the TWRP screen. If you don't see the TWRP screen and instead see a floating ring that says “Erasing”, don't worry. Let if complete and try flashing TWRP in fastboot again.
In TWRP, you'll be greeted by a screen that says “Swipe to allow modifications?” Swipe it, then go to the Wipe tab. Go to Wipe, then Format Data, then type yes, then go to the Reboot tab and select Recovery to reboot into TWRP again. If you're prompted to install the TWRP app, don't bother.
Once you've rebooted into TWRP again, it's time to disable encryption and root the phone. Download the latest zips here and here. Skip downloading them if you already put them on your SD card earlier. On your PC, push the files to your phone using the command “adb push path/to/file.zip /sdcard/”. You can drag and drop the file into Terminal or Command Prompt to copy file path. Then go to the Install tab in TWRP and select the no-verity-opt-encrypt.zip, tap Add more zips, then add the root zip, then swipe to flash. Let the zips flash, then tap the Reboot System button when it's done. Your phone will take a little longer to boot and might reboot a couple times.
Once you're back in the OS, go through the setup wizard. Set up Magisk. If you stay on stock, you should install an app like Quick Reboot Pro from the Play Store to make it easier to reboot into recovery. Now reboot back into TWRP and go to the Backup tab. If you have a SD card, set it as the backup location. You can enable compression if you want. This will make a full system backup that you can restore from as long as you have TWRP. If the backup takes up too much space, you can put it in Google Drive or your PC later on.
You are now ready to install ROMs!

Please explain more in detail so you can be helped better In what ways? What are you doing to get into bootloader mode? I've never had any issues on my T-Mobile Stylo 2 plus. Are you trying to get into bootloader using buttons manually or through twrp or adb?

You hold volume DOWN and power then soon as screen comes on and you see LG you let go of the power button and then immediately press power again and you never let off volume DOWN. That doesn't work?

Hey there, I've got the LG K530F, is there any chance of unlocking it? I looked up the LG developer website and it's not listed in there, filling that form will just lead to a popup regarding that. I thought about downgrading it back to MM (Android 6.0) using the K350F10d_00_02221.kdz firmware package aiming to be able to run fastboot oem unlock, but I'm afraid of getting it bricked. Anyone tried it? I recall doing something like that to unlock the LG Optimus L9, but that one was way older and had much weaker security measurements.
Can't get into Bootloader
Hi i have a LGL82VL and when trying to use adb reboot bootloader it just restarts, And when using Vol Down and Power it just comes to the factory reset page (Hard Reset)
Any ideas on how to get to the bootloader? i checked with fastboot devices while on the hard reset page and got nothing. Any Ideas?
