Flashing cwm and rooting on unlocked BL P760? - LG Optimus L9 P760, P765, P768, P769

Hi everyone,
So after deciding whether to do it or not, i finally unlocked my BL yesterday. At least when i dial the secret number and look at BL info, it says "UNLOCK".
But I've been trying to flash cwm and rooting but it seems my device is not being recognised in cmd.
And i am having difficulties to install fastboot drivers again because my device is not showing up at all in device manager.
If you could kindly list some simple instructions on how to flash cwm and rooting on unlocked BL (Before you ask, yes i went through all the guides with no avail) or help me to install flashboot drivers properly, it would be appreciated.
Thank you and good day.
EDIT 1: I can boot in fastboot mode, But when i do adb devices, driver installation fails and thus the command for flashing cwm says "waiting for device" and never flashes.
EDIT 2: From what i have searched from previous posts , i need to wait 30mins, I will do that and report.... Hopefully it will work

If you can boot into fastboot then do fastboot devices, adb devices are commands in adb mode, not fastboot mode, instead of flashing through adb use fastboot flash , hope I help!

Sorry,
I actually did what u said.
But when i type the command (in cmd) : C:\Android>fastboot devices ---> The command is accepted and there is a driver installation which fails.
Even then i continued and typed : C:\Android>fastboot flash recovery recovery-clockwork-touch-6.0.3.1-p760.img
But with the second command, it simply says "waiting for device" in the command window, but nothing happens.

Can you boot your phone normal now at all or not?
If you can, use BTDAG's guide in my signature and install the custom recovery using the flashrec method.
I cannot it stuck at the "HERO" boot screen :'(
what I can do is that I can use the adb shell the browser the files inside the phone.

I can't go into the recovery mode.
I can only go into the fastboot mode.
Try this,... Go into fastboot.
Hit BACK to enter the fastboot bit.
I should now say FASTBOOT USB or something similar.
Then you need to cd into the right directory using CMD.
example,... I have to type...
cd c:\sdk\tools ................But it might be different on yours.
then type
fastboot devices
It should bring up your device serial number.
Then type
fastboot oem rebootRUU
fastboot erase cache
Then reboot.

try the HEROIMG.zip method
Hello,
just another idea:
- download an original RUU.exe (preferably of an older version, rootable) and extract rom.zip (a lot of guides in the forums)
- rename to HEROIMG.ZIP and put in sdcard root
- restart hero with volume down pressed
- normally it should find the heroimg.zip and flash it and you are back to normal

[SOLVED] How to safely update TWRP 2.4.4.0 to 2.5.0.0 on my HOX+ International?

Simply flash the image using hasoon's toolkit, that is the easiest way.
Else you can use ADB tool...

Like mentioned by the guy above, use the toolkit or use the command fasboot flash recovery (recovery name).img
e.g.
In command prompt (CMD) type
fastboot flash recovery recovery.img
That should do the trick. Since its a recovery flashing, hardly anything goes wrong. HOWEVER, DO CHECK THAT YOUR PHONE IS CONNECTED. I cannot emphasize the importance of this. It caused me a massive problem so i'm warning you before hand. Type into command prompt, adb devices and check that your device/s is attached. That's it! :laugh:

Thank you guys. You mean I don't have to remove the existing TWRP version and just use hasoon's tool to update the old TWRP to 2.5.0.0?

in cmd try "fastboot devices" you should see your device, if not ,install drivers and try again it should work
Thats what happens when i type fastboot devices

Typical causes of that:
Not having the fastboot.exe in the folder you are working in on the PC.
or
Not in bootloader mode on the phone.

fastboot.exe is in the folder i`m sure .. but i run the phone in fastboot mode .. what is bootloader mode ?
Ohhh...is this on the D5503? Sony Xperia Z Compact? You sure you're in fastboot and not flashmode? What color is the LED? If you go into your device manager, does it show your device with or without an exclamation mark? Might have some helpful info here:
http://techglen.com/2014/03/26/inst...-14-3-a-0-681-4-4-2-kitkat-official-firmware/
I think you might have to unlock the bootloader before regular fastboot commands work.

Ok, so what are you trying to do in fastboot?

It seems like the bootloader is not unlocked then. You won't be able to install a kernel without doing that first.

NNow dial *#*#7378423#*#* and navigate to Service info > Configuration > Rooting Status
Now look for Bootloader Unlock Allowed
If Bootloader Unlock Allowed: Yes, then you may proceed
i tried that and it said yes :\
Ok, good deal. That means you can go through the steps to unlock the bootloader, not that it is already unlocked. Refer to the guide I posted and it has what other steps you need to do to proceed.

yes it reboots showing blue LED when i hold volume up while i connect the usb .. still the same problem :\
Try replacing the normal fastboot command with this:
fastboot.exe -i 0x0fce
Just to clarify - You signed up @ Sony's dev site and they emailed you the key to input in the commands to unlock the bootloader?

I think you are not booted in boot loader, give following command
adb reboot-bootloader
then after few seconds check whether you booted in bootloader or not.
fastboot devices
It will show your device.
fastboot flash recovery recovery.img
It will flash recovery.
no.... I'm in bootloader
First i enable usb debuging ->vonnect my mobile to pc ->in cmd gave adb devices-> adb reboot bootloader->fastboot flash recovery recovery.img

Boot hang

hi all,
i have a rooted vivo air lte with supersu.
i wanted to install magisk with the manager 8.0.3 (the boot.img from stock rom i extracted to downloads folder) by choosing direct install.
now the phone hangs on the bootlogo.
i can boot into recovery and choose "apply update from adb"
i installed fastboot and adb on the pc.
in the terminal command "adb devices" i see "devicenr sideload".
when i enter fastboot devices, there is no device shown.
im not sure if i have unlocked the bootloader when i rooted the phone a year ago..
so what do i have to do now to get it booting again?
thanks for the help!

Device is configured to get booted in "Sideload" mode what is a variant of ADB mode.
Try this
Code:
adb devices
adb reboot
to return to "Normal" mode.
no, this is what i have chosen in the recovery, otherwise i dont get any device listed in the terminal..
@schlunk
Once being in the Android Recovery Mode and you select option Reboot system the Android device simply gets restarted: the actually configured ADB mode herewith doesn't get changed / reset.
when i enter "adb reboot" in the terminal its "error closed"..
is ther e something i can sideload then to solve this, when the phone is waiting for the package to sideload?
thanks for helping!

QFIL is the answer.
this is a flasher like odin?
so can i just flash the boot.img, that magisk wrote back to the stock one?
and like i said im not sure if the bootloader is unlocked, does it play a role in this?

thats exactly the file i downloaded to extract the boot.img and see what happend
i dont want to flash the complete stock firmware again with the risk that my phone is bricked after that.
there must be some easier solution for this??
cant i just flash what magisk messed up?

Nope, I don't think there is.
Depends if that boot is same that was in your device. See the video
and the thread too: https://forum.hovatek.com/thread-31476.html
The boot should be the same, the firmware is exactly the same like in the phone regarding the label.
So with this linked method, flashing a single partition means, the boot.img can be flashed solo, without the need of flashing the whole firmware?
And when that doesnt work, i still could flash the whole firmware then as last resort?
That what I would do... Good luck!
