Flash new recovery to Wildfire the Easy Way

I found this after searching around for ages on a way to upgrade the recovery on my Wildfire/Buzz, all the friggin fastboot methods weren't working. This worked straight away, no errors, no problems.
Flash a New Recovery Image
1. Find the recovery image you want and MAKE SURE IT IS FOR YOUR PHONE (should say in where you download it what phone it is for)
2. Rename the filename of the recovery image EXACTLY as it is written to recovery.img
3. Put the recovery image file on the SD card (not in any folders)
4. Download Android Terminal Emulator from the Market (there are a few different terminals in the Market some have an onscreen keyboard and some don’t experiment till you get one, also hold down Menu in some of them to bring up the onscreen keyboard if you don’t see it)
5. Open the Terminal program and type the following (with hitting enter at the end of each line):
su (press enter)
(at this stage it will ask you for superuser permission to access your core system. Allow the access)
su (press enter)
flash_image recovery /sdcard/recovery.img
6. Phone should pause for a second and then show you a new blank line. Turn it off and back on by holding down Home and Power to ensure it flashed correctly. Done.

Error
flash_image: not found
Sdcard is fat (not fat32). Any idea.

EDIT - Sorry, Wrong method, here's the correct one:
First, make sure you have the latest Android SDK, then:
Connect the device to your computer
Copy recovery.img to the root of your SD card
Open term on your computer and run: adb root adb remount
Flashing the custom recovery adb shell flash_image recovery /sdcard/recovery.img
Reboot into recovery to make sure the process was successful.

3xeno, your method is the same as yusuo's.
he directly use console on android to send command "flash_image recovery /sdcard/recovery.img" after become root ("su")
pro: no need for PC, con: hard typing on the device
you ask adb to execute on the device the command "flash_image recovery /sdcard/recovery.img".
pro: single command with a real keyboard; con: need for PC and cable

fastboot works only with s-off,if you don t have s-off it will not work .-. (or if you don t have the right files)
anyway this metod didn t work for me
fastboot is the best and more simple than this,anyway is there a metod to flash recovery from the phone?

I know, but the method on the handset itself didn't work for him. Hence, just suggested the alternative of the same technique as in the OP

My phone has alpharevx s-off. I thought there was no need of pc and everything can be done from phone itself. But still it didn't work for me. Same error.
If there was a need of pc terminal, maybe the 1st post needs to be clear.

After a bit more reading, it seems "flash_image" must be present in /system/bin for it to work.

Yes. Now I can confirm that it works when there is "flash_image" (a file with no extension) is present in the path /system/bin/. Also the permissions of flash_image needs to be executable. Just flashed the recovery partition .
Download flash_image from the link given by 3xeno. The OP needs to be updated.

HELP!!!! trying Install CWM on zv8

Ok so here it is almost day 2 trying to install CWM on zv8 after using "mt's easiest way to keep root thru zv8'. (Oh and by the way MT your the MAN). Now getting to zv8 was easy, But getting the recovery installed is another issue all together. First started with the AIO bat. file which installs cwm (kudos to MT and djrbliss). And it reads
"system cannot find the path specified'.
SO ok well apparently the computer isnt reading the phone found out the driver has issue shows the error message(on both my laptops).
ok lets try the terminal emulator with
brad6360 said:
1) Download the cwmrecovery.img to your SD. ( I downloaded MT's zip file and then extracted all with root explorer, but you only need the cwmrecovery.img file.)
2) Use root explorer to copy or move it to the /data/local/tmp directory (make sure permissions are set to r/w/exe).
3) Launch terminal emulator and type these commands:
su
mount -orw,remount /dev/block/system /system
mount -orw,remount /dev/block/data /data
dd if=/data/local/tmp/cwmrecovery.img of=/dev/block/mmcblk0p14 bs=4096
rm /data/local/tmp/* 2>/dev/null
4) exit terminal emulator and then reboot.
You can then try the vol down+power button combo upon boot to enter CWM.
Good luck.

didn't work and I the local.prop file in the data folder.
Someone PLEASE HELP!!!
(not a noob or expert but I can read and follow directions lol)

Are you sure you still have root level access?
Does adb detect your phone at all?

Still have root access I used root explorer to add the local.prop.
Adb recognizes my phone it shows a serial number under adb devices
Is there a way I can flash cwm in adb?
Sent from my VS910 4G using XDA

Use the newest aio from Mt. It worked for me. The simplest way is to flash the v7.tot then 'JUST' root, create the local.prop file, then ota to v8. Then continue on with Mt's aio to install cwm. Don't worry about having complete root access (cuz I didn't, but had cwm). Flashed broken out and haven't looked back.
--My REVO is Broken, tweaked, SC'd, and TB'd. Just awesome!

Thats where I'm stuck. I'm on zv8, using mt's easiest AIO to update from zv7. The AIO for cwm isn't installing nor through the terminal emulator. Any other suggestions?
Sent from my VS910 4G using XDA

What happens when you go into recovery? Is it the stock recovery? Stock v8 didn't have the option to boot into recovery. Just a thought. When I did it I got a lot of errors, but it took.

I have the same problem, Even when i Flash zv7 tot and try old AIO it says
Cannot find specified path
and i am not a noob and have broken out an old revo with mt's help but this new one with pre loaded zv8...No luck yet
had to manually push

I'm glad that I'm not the only one having this issue

Can you use Root Explorer to check and make sure adb is pushing the image file to your phone? Look in this directory: /data/local/tmp/cwmrecovery.img
You could always do this manually using adb. Here's how.
1. Open the ZV8CWMRecovery folder on your PC.
2. Double click the 'Files' folder to go into that directory.
3. Highlight/select and copy the address of your current folder location on your PC. It will look something like this:
Code:
C:\Documents and Settings\username\My Documents\Downloads\ZV8CWMRecovery\Files
4. Click Start>Run>type 'cmd' and hit enter/return to open your command prompt.
5. Type 'cd', hit your spacebar, then paste your address which you copied in step 3 into your command prompt, hit enter/return.
6. You should now be positioned in the folder containing the adb and CWMRecovery files.
7. Type the following to copy the CWMRecovery image to your phone:
Code:
adb devices
adb remount
adb push cwmrecovery.img /data/local/tmp/cwmrecovery.img
adb shell dd if=/data/local/tmp/cwmrecovery.img of=/dev/block/mmcblk0p14 bs=4096
adb shell "rm /data/local/tmp/* 2>/dev/null"
adb shell rm /system/etc/install-recovery.sh
adb shell rm /system/recovery-from-boot.p
adb shell rm /data/local.prop
adb reboot
Phone should reboot. Try and boot into CWMRecovery after it reboots.

idk if I'm not doing something right or wrong. I have usb debugging and internet connection, and I'm getting "remount failed: operation not permitted".

I had the same issue but following these instructions helped me, what finally helped me was typing a wrong command wich gave me a help menu with all the commands, the important one being "adb reboot [Recovery:Bootlaoder]"
adb reboot recovery did the trick, then wiped flashed broken out and sooo happy to be done with it.
after pushing CWM in command prompt of course

I'm also getting "remount failed: operation not permitted" when trying adb remount in the command prompt just as mrand1 apparently did.
I (perhaps noobishly) skipped that step and did adb push cwmrecovery.img /data/local/tmp/cwmrecovery.img but after trying the next step got cannot open for write: Permission denied.
I'm trying to get back to Broken Out 1.1 - when it first came out I successfully downgraded to zv7 by flashing the .tot and then doing the OTA update, but now when I try to do that I can't seem to get the OTA to start downloading. I flashed zv8 tot in order to test the latest root method (which works) I just can't get CWM on there now - I don't seem to have any recovery at all actually. Any help would be appreciated.

I did the same thing, flashed to zv8 tot, was able to root but was unable to flash cwm recovery. I tried manually doing it and running MT's AIO. It's telling me permission denied on all of the steps except the push cwmrecovery.img. It appears I do not have any recovery either. Trying to get to Broken Out! Any help is appreciated, thanks guys!

For what it's worth I also tried that with the same results.

I finally got this to work much more easily thanks to a quick talk with mtmichaelson. Here's the method:
1) Get to ZV8 (I got there via LGNPST)
2) Root using the tool found here: http://forum.xda-developers.com/showthread.php?t=1621625
3) Open a Terminal Emulator
4) Type: su
5) Hit enter
6) Type: echo 'ro.kernel.qemu=1' > /data/local.prop
7) Press enter
8) Reboot
9) Use the ZV8CWMRecovery.bat found here: http://forum.xda-developers.com/showthread.php?t=1583023

Man, that was too easy!
Thanks for posting this slimzim. This worked straight away for me, I'm installing Broken Out as I type! I'm actually a little glad this happened because now I'm a little more familiar with terminal emulator and what local.prop does. Never had to use it in the past. This is exactly the second phone I've ever rooted and am usually able to just use AIOs.
And of course, thanks to mtmichaelson for chatting with you about it and doing all the hard work in the first place!

If you've done all steps exactly it should work. I went through a ton of other "fixes" that didn't work, I believe the key here is when you use the terminal emulator directly on the phone to create local.prop. I was trying to create local.prop in every way but that, and until I did it directly on the phone did I have success.
Good luck!

local.prop missing
I used the Easy ZV8 All in One Rooting Tool, and have no sound at all like a couple of other users. One of the suggestions was to rename the local.prop file in the /data folder to local.prop.bak.
I assume this is the /data folder in the internal folder? When I did the steps for the all in one rooting tool (coming from rooted zv7), there is no local.prop file in my /data folder to rename, yet I still have no audio for ringtones, phone calls, etc. except for the boot up sound on the splash page.
Any ideas why my local.prop file isn't even there? I even tried copying the one from the mtmichelson zip file into there, still no avail. Thanks!

I have the same issue. I used the echo command in term emulator and the local.prop file was there. rebooted and the file is gone. I have root but cannot install cw recovery. I have tried AIO, adb, and terminal emulator but nothing makes it stick. Any help would be greatly appreciated

[ROOT][10-29-13]How to Manually Root the Nvidia Shield

Introduction
The following procedure will walk you through the step-by-step process for gaining root access on the Nvidia Shield.
Note: You must have an unlocked bootloader before you can proceed with this tutorial!
A tutorial on how to unlock your Shield's bootloader can be found here.
This tutorial also assumes how have the correct ADB and Fastboot drivers installed for your device, for a tutorial on how to install the ADB and Fastboot drivers for the Shield please look here.
Due to the nature of modifying devices system files the standard XDA disclaimer applies: I take no responsibility for bricked devices due to the following rooting procedure, no warranty express or implied is given, I will not be held responsible if you mess up your device by following this procedure!
Procedure
Before you begin please make sure to read and re-read the whole procedure, making sure you understand the directions.
1. Download the "Superuser-su.zip" file and the "roth-insecure-boot-63.img" file that are attached to this post. After you have downloaded the files, extract the contents of the "Superuser-su.zip" file which contains Superuser.apk and the su binary, and move them to your ADB and Fastboot folder on your computer. Also transfer the "roth-insecure-boot-63.img" to your computer's ADB and Fastboot folder.
MD5 Checksum for "roth-insecure-boot-63.img": F8BA5C48D0323D99E2A748C77BF647F6
2. Connect your Shield to your computer using your USB cable. For maximum reliability please connect the USB cable to a USB 2.0 port directly connected to the motherboard as USB ports on the front of a case panel or USB 3.0 ports can sometimes be unreliable.
3. Now that your Shield is connected to your computer make sure that "USB debugging" is enabled under the Developer Options section in the system settings menu (If the Developer Options section is hidden, go to the About Phone/About Tablet section of the system settings and then tap on the item that lists the Build number 7 times or until it says "You are now a developer" and the Developer Options section becomes visible in the system settings).
4. Open a command prompt window (cmd) in your ADB and Fastboot folder on your computer and issue the following commands (If you are new to using ADB and Fastboot I would recommend checking out this excellent guide to get you up and running):
Code:
adb reboot bootloader
Now that you are in fastboot mode let's make sure that the computer see's our device:
Code:
fastboot devices
If the computer see's our device then we can proceed, if it doesn't see your device make sure you are in fastboot mode and have the correct ADB and Fastboot drivers installed for the Shield.
Now we will be booting an insecure boot.img (ro.secure = 0) to our device to allow us to gain root acess:
Code:
fastboot boot roth-insecure-boot-63.img
After the insecure boot.img finishes flashing the device will automatically boot up using the insecure boot.img.
5.First we need to mount the /system partition as read/write so we can modify it:
Code:
adb shell
mount -o rw,remount -t ext4 /dev/block/platform/sdhci-tegra.3/by-name/APP /system
exit
6. Now we need to run the following commands to push the Superuser.apk and su binary to there correct positions and set the proper file permissions:
Code:
adb push su /system/xbin
adb push Superuser.apk /system/app
adb shell
chmod 6755 /system/xbin/su
chmod 644 /system/app/Superuser.apk
mount -o ro,remount -t ext4 /dev/block/platform/sdhci-tegra.3/by-name/APP /system
sync
reboot
7. After the device reboots and power on into the Android Operating System you should see Koush's Superuser app in your app-drawer and you should be rooted. If you would like to verify root access you can download and run Root Checker Basic from the Play Store here. Enjoy!
Credits: Koush for his open source Superuser.apk and the su binary (https://github.com/koush/Superuser)
If users would like me to create a 1-click root process of this please let me know and I will do so .
If you are stuck with the rooting procedures I would recommend checking out this great video tutorial by wwjoshdew.

Alternatively the following works in almost one click (one fast boot, actually): https://github.com/linux-shield/shield-root

It's just whole unlocking thing and giving up your devices warranty. NVIIDA being able to decline your RMA if your fan goes out and the unit overheats. Or if the scree dies (for example). I'll do it, just gotta grow a pair first.

I did my RMA and nvidia sent me a new 1. So you should get your new shield b4 you send it back if you happen to root it and the screen dies.

This is a pretty complicated way of rooting. All I did was unlock the bootloader, flashed Clockworkmod Recovery, and then flashed the SuperSu zip with that. Rooted! As easy as a Nexus.

This method is actually nearly the same. It's a bootable self-contained image (like recovery is) that mounts the correct partitions, installs the necessary bits, and is done.

I haven't done this yet ... but could you also provide instructions on how to revert? I ask this as it would be nice to know that there is a back-out plan.

To unroot your Shield since you are only temporarily booting an insecure boot image rather then flashing it, if you run the following commands in either ADB shell or terminal emulator will unroot your device:
Code:
$ su
# mount -o rw,remount -t ext4 /dev/block/platform/sdhci-tegra.3/by-name/APP /system
# rm -f /system/app/Superuser.apk
# rm -f /system/xbin/su
# mount -o ro,remount -t ext4 /dev/block/platform/sdhci-tegra.3/by-name/APP /system
Then after you have entered those commands reboot your device and you'll be unrooted.

The original factory restore image that you can be flashed to your shield to return it to stock can be downloaded from here, along with the factory image extraction instructions (Under the open source resources section), as well as the factory image flashing instructions.

Does anyone if the root stop you from updating the device like GS4?

Simply rooting does not. I was rooted and updated. You lose root but can just reroot it like the first time. I am not sure if you have a custom recovery installed though. I haven't used one on the shield.

I am using the window 8 and I can't get the command prompt to work either directly open or open it as administrator to type the command. Any idea what I am doing wrong?

When you mean you can't get the command prompt to directly open what do you mean by that? Does command prompt not open or run at all when you open it? Do you have ADB and Fastboot installed and the files listed for this procedure in your ADB and Fastboot directory? The Shield I rooted was my friends and he's on vacation right now so I unfortunately can't make a video right now , but I'll still be happy to try and help you through the procedure.

[Q] Recovery not sticking - adb help

Hi guys, I would really appreciate some help. I am able to root my gear and transfer the TWRP via odin. But when I reboot into recovery it just goes back to the stock launcher. I read this in the developer thread:
IF YOU FIND THE RECOVERY IS NOT STICKING & YOUR GEAR WIPES WHEN ATTEMPTING TO ACCESS RECOVERY AFTER FLASHING.
YOU MUST ROOT YOUR GEAR PRIOR TO INSTALLING TWRP AGIAN & RUN THE FOLLOWING COMMANDS IN ADB.
*NOTE* YOU WILL HAVE TO ACCEPT A SUPERUSER REQUEST POPUP WHEN EXECUTING "SU" COMMAND.
*NOTE 2* PROBABLY A GOOD IDEA TO RUN THIS PRIOR TO FIRST INSTALLATION, TO SAVE TIME.
Code:
$ adb shell
$ su
# mount -o rw,remount /dev/block/mmcblk0p20 /system
# rm /system/recovery-from-boot.p
IF YOU DELETE THE "RECOVERY-FROM-BOOT.P" FILE YOU MUST RELFASH TWRP RECOVERY.
I have rooted and installed roms on phone before but working in the developer tools is new to me. Can anyone explain exactly how and when to do this during the TWRP recovery install process? Or possibly just point me to a how to or youtube on basic adb commands? I have searched and it looks super complicated. Just need to know how to run these 3 commands.
THANKS!

i have the exact same issue, is there any answer for this??

Well it's been well over a year since I did that but let's see if I can help..... Before I start I'm hoping you've already enabled adb debugging on the gear and downloaded adb onto your computer. I believe you run the commands after you've run cygnia but before you flash twrp. You run the task from a command prompt from your pc. I'm pretty sure you don't include the $ or #. Before you start try the adb command- adb devices from the command prompt on your pc. That'll let you know if the gear is connected. I remember being a bit intimidated by it all as it was different to any other flash I'd done. In reflection it's very easy, type the line in a command prompt, press enter, wait for the cursor to come up again, type the next line. As for guides..... I can't remember which one I used but there's plenty out there.

Over the last few months development on the LG L90 has made some great strides, up to the point where we can actually install roms! In order to do this, however, you'll need an unlocked bootloader.
The problem that arises is that there are different models of the L90, being the D405, the D405n, the D410 and the D415. For most of the models the unlock process is very similar, but for the D415 another method is needed.
This guide is aimed at explaining the entire unlock process in a complete and simple way, so even if you have no experience flashing custom recoveries or roms at all, you should still be able to follow this guide. If you run into problems, please just post a reply or send me a PM and I'll do my best to help you.
First of all I'd like to note that I did not develop any of the bin files or apks in this guide, I'm only collecting all the unlock methods in one place for easy reference. Therefore I am not responsible for you bricking your device or causing any kind of damage to it. You follow this guide AT YOUR OWN RISK! That being said, let's get to the unlocking!
What you'll need to unlock the bootloader
1. A rooted LG L90
You can root the phone by going to https://towelroot.com in your mobile browser and tapping the lambda sign. Save and install the apk (make sure unknown sources are enabled in "menu > general > security"). Google will warn you about the app, this is because of the exploit which will enable the root access. Execute the program and tap "make it ra1n", then install supersu from the play store. Open supersu and choose to rebuild the binaries. This will fail, but after a reboot supersu should be installed and working properly.
UPDATE: If towelroot doesn't work for you, you've probably got the L90 with an updated firmware. In that case you can follow this guide by @gdjindal to obtain root access. Afterwards you can follow the rest of this guide again.
2. Have adb installed.
just download the Android sdk and install it or, if you don't care about the SDK itself, the minimal adb from the bottom of this post (thanks to @shinobisoft for the upload). Now add the C:/path_to_the_sdk/sdk/platform-tools to your windows PATH variable (Windows 7: right click my computer > properties > advanced system settings > environment variables) or the foler in which adb.exe is located if you downloaded the minimal adb..
On your phone go to "menu > general > about phone > software information" and tap build version a few times untill it says you're a developer, then go to "menu > general > developer options" and enable usb debugging. Connect the phone with your PC and choose to connect in software mode and install the drivers and tools. When you get a message on your phone that your PC want to access usb debugging make sure you check the checkbox and accept. Now open a cmd prompt and type "adb devices" without the quotes. If it shows a series of letters and numbers followed by device, you're good to go. If it says unauthorized, you haven't accepted the prompt on your phone yet. If your device doesn't show up at all you haven't installed the drivers correctly.
3. Find out which device and software version you're running.
Go to menu > general > about phone > Hardware information for your Model number. Mine is LG-D405n, so my model is D405n.
Go to menu > general > about phone > Software information for your Software version. Mine is V10b-EUR-XX, so I've got version v10b.
4.1 If your model number is D405, D405n or D410, you'll need a modified aboot.bin to unlock the bootloader.
Go to the bottom of this post and download the file with your model and software version. I used the L90_D405n_v10b_hack.zip. Extract the aboot.bin in the zip file to a folder on your PC.
4.2 If your model number is D415, you'll need another method to unlock the bootloader, which is explained in this thread made by @aSuperSaiyanG0D.
Unlocking the bootloader on the D405, D405n and D410
1. Open a cmd window an CD to the folder where you've saved the aboot.bin you've downloaded in step 4.1
2. Execute the following commands:
Code:
adb push aboot.bin /storage/external_SD/aboot.bin
adb shell
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/storage/external_SD/stockaboot.bin
dd if=/storage/external_SD/aboot.bin of=/dev/block/platform/msm_sdcc.1/by-name/aboot
Right after the su command, supersu will give you a root request on your phone that you'll have to accept!
This will also make a backup of your current aboot partition as stockaboot.bin on your external SD card. If you don't have an external SD card, this won't work and you'll have to use /storage/emulated/0 (this is a zero, not the letter o) instead of /storage/external_SD/ like this:
Code:
adb push aboot.bin /storage/emulated/0/aboot.bin
adb shell
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/storage/emulated/0/stockaboot.bin 5429599
dd if=/storage/emulated/0/aboot.bin of=/dev/block/platform/msm_sdcc.1/by-name/aboot
3. That's basicly it, you can now install a custom recovery. I suggest downloading the latest TWRP (2.8.0.0 right now) from @shoxxy's thread, which can be found here. Just use ROM Toolbox to install it, choose rom installer, press settings > flash image and select the TWRP image from @shoxxy's thread. Afterwards you can boot to recovery using ROM Toolbox, or by shutting down the phone, holding volume down and power untill the lg logo shows, then releasing and immediately pressing those buttons again. You should get a screen asking to perform a factory reset. Choose yes twice (don't worry, it wont actually perform the reset) and TWRP should boot up. Now you can create backups and install custom roms too!
If you're a fan of cyanogenmod, you should visit @Quarx's thread, which can be found here. His CM11 is already mostly functional (right now on some models the front camera doesn't work and the ir blaster doesn't have any software, but most other functions actually do work very well, while it is faster than LG stock and gives almost twice the battery life), so if you like CM it's a thread worth keeping an eye on.
Flashing back the stock rom (in case of a brick)
If you've bricked your device, or want to revert to stock for any reason, you can follow this guide made by @gdjindal.

So, I did everything, but when I try to do the 4.2, I cant do it.. The reason why is because it says "No stat file"

If you have a problem with step 4.2 only, I assume you have a D415 and you should actually ask this question in the thread that step 4.2 links to. Or isn't that what you meant?
EDIT: please note that step 4.2 is for the D415 ONLY.

Sorry, my bad, I though tha step 4.2 was the wole thing that comes next, my device is D405

No sweat If you've completed step 4.1, just head to step 1 of the next section and you should be good.

Open a cmd screen (go to start > all programs > accessories > Command prompt) and from there run this:
Code:
cd Desktop/Folder_you_put_the_aboot_in
adb push aboot.bin /storage/external_SD/aboot.bin
adb shell
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/storage/external_SD/stockaboot.bin
dd if=/storage/external_SD/aboot.bin of=/dev/block/platform/msm_sdcc.1/by-name/aboot
if you use an external SD card. Else run
Code:
cd Desktop/Folder_you_put_the_aboot_in
adb push aboot.bin /storage/emulated/0/aboot.bin
adb shell
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/aboot of=/storage/emulated/0/stockaboot.bin
dd if=/storage/emulated/0/aboot.bin of=/dev/block/platform/msm_sdcc.1/by-name/aboot
Mind that I've only tested this using the external SD, but it should work both ways.

That is stange, never had that error myself. In that case I would try another way to put the aboot.bin on the root of the SD card (google drive for instance) and continue from the adb shell part..

BTW: what's the output of

Can't I just simply paste it on my SD card?
Edit: I think I found what my problem was, something in developer settings..
2nd Edit: Nop, it still gives the same read-only error..
3rd Edit: The output of adb devices is LGD410bc(..) Device

Strange, but yes, you can simply paste it on your SD card and continue from the "adb shell" line. You can also try
Code:
adb shell sysrw
before the push command to mount the filesystem as RW. If you do this, it is recommended to use
Code:
adb shell sync
adb shell sysro
after the psuh command (so you'll mount the filesystem as RO again).

Where did you get the not found message? And what do you mean you flashed stock again? If you couldn't execute the dd commands then your bootloader is still locked and all you've done so far is root the device..

UPDATE: I don't get a response, but it seems this user previously flashed the wrong aboot.bin (or did something else, unfortunately he's not being very clear on that) so please only follow this guide when you have a stock recovery + aboot partition. If you did try some things before, please flash the stock rom back first and then follow this guide.

Thats awesome! Thank you! :cyclops:

No problem! Just let me know if you run into any problems so I can update the guide accordingly (and hit the thanks button if it worked of course).
