[Q] Troubles with unlocking bootloader both Windows and Linux. Encrypted BL ? - LG Optimus L9 P760, P765, P768, P769

Hi,
I'm new here so I'll make it the most clear I can.
Device: LG P760
Date of production: on battery it is 02.2013 but it was in repair back in the middle of 2014 and god knows what it has been done there. Probably change of whole mainboard
Soft: Stock 10(someting) on Android 4.0.4 -Branded > Update to 20h JellyBean - Branded >>service>> not branded 20h > Flashed manually 20b Europe Open
EDIT: AP Bootloader Version: LK May-2012 (From hidden menu)
Target: Unlock bootloader
What have I done so far:
Windows 7
1. Standard console
Code:
adb reboot oem-unlock
2. RomToolkit 2
3. LGL9Toolkit
4. Bunch of scripts found here
5. Omap4boot
Result: Pretty much reboot of system without any effects
Linux Ubuntu 14.10
1. Standard console
Code:
adb reboot oem-unlock
Result: reboot of phone without any effects
2. Connecting via fastboot and
Code:
fastboot oem unlock
using modified by myself script found somewhere
Code:
#!/bin/sh
which fastboot || echo install fastbooot first, e.g. on ubuntu sudo apt-get install android-tools-fastboot
which fastboot || exit
echo 'Connect LG L9 *without battery* to PC using data cable'
sudo ./usbboot p940-aboot.2nd p940-u-boot_fastboot.bin && echo usbboot ok || exit
echo 'DO NOT disconnect usb cable. Insert battery, then press enter'
read x
sleep 10
echo fastboot devices:
sudo fastboot devices
echo 'UNLOCK'
sudo fastboot oem unlock
which resulted in:
Code:
/usr/bin/fastboot
/usr/bin/fastboot
Connect LG L9 *without battery* to PC using data cable

That is pretty much everything. I've read about some magic cable and something about encrypted bootloader but I'm more than confused now. Am I doing someting wrong, especially on Linux (more acquainted in this type of system)? On Windows I have to exclude drivers problems, tried on 3 different machines, waited long before unlocking

Well, I'm in your same situation, but mine has been produced the 31/5/2013, so it have an encrypted bootloader.

P778G Soft Bricked

Hi, well a friend of a friend gifted me an LG L9 Model P778G (Carrier: Personal Telecom Country: Argentina). The only thing that he told me was that he dropped his phone and it didn´t turn on back anymore. I externally charged the battery. The phone doesn´t turn on, sometimes when I connect it to my PC (windows XP) it recognizes it as OMAP4430 but only when battery is not connected (when I connect battery it says unrecognized usb device, when I press Vol+ and Vol- with or without battery it also says unrecognized device. Already tried to flash with LG Mobile Support and KDZ but it says phone not connected. I would like to know how can i get the phone back working and if possible with Jelly Bean (I don´t know if phone had JB or ICS, but of what I almost certain is that it was never modified because it belonged to an old person). Please explain with detail though I'm not used to LG (HTC & Samsung owner) and don't know much of it.Thanks to everyone!

I believe you still need to install the fastboot driver again.
Take a look at lelus fastboot script thread here - http://forum.xda-developers.com/showthread.php?p=41768774
Read the part in the thread about installing the drivers and about the original fastboot thread.
That should get you ready to be able to do the offline or online kdz flash

Hi, now the phones stays for a while, but still can't get it recognized at KDZ or LG MST.
PS: when installing fastboot drivers after connecting battery it says an LG Logo should appear on screen but it doesn't, thanks for your support

You can try to run the B2CAppSetup.exe, after opening the app, select you phone model and letting it install the drivers, then unplug and plug the USB cable back in and see what happens.
Edit - Also when you connect the device to your PC when in fastboot mode what does it show up as in the PC's device manager?

I'm not sure yet... We need to get the ICS Uboot and Xloaders to install so that you can get into S/W mode.
I'm trying to research on an answer for you.
These L9 are a real pain in the butt.

[GUIDE][BRICKED] [BOOTS ONLY TO RECOVERY][All ASUS TRANFORMERS]

This is a general users guide to unbrick your Transformer tablet.
This guide will help you if your Asus tablet will only boot into recovery
and the command
Code:
adb reboot-bootloader
does not work to get you booted back to bootloader screen ..
If the above command works then skip to the first fastboot command ..
WHAT YOU NEED
An Asus tablet that will only boot into recovery …
Woking adb and fastboot on your PC
Windows drivers (if using Windows)
A fully charged tablet
Asus data cable
Stock firmware blob (from Asus's web site, make sure you get the right one)
_that's bootit.ko (unzipped and placed with fastboot.exe)
Downloads
Asus Stock firmware---MAKE SURE YOU GET THE CORRECT SKU FOR YOUR TRANSFORMER TABLET
click me
_that's bootit.ko----click me
INSTRUCTIONS
Extract your stock firmware in your downloads folder twice...You will see a blob file rename it boot.blob and move it to the same folder as your fastboot.exe or if in linux to your home folder
Unzip the bootit.ko and place it wth the above blob file.
Let start with this command to make sure that your PC can see your table as an ADB device in recovery
Code:
adb devices
OUTPUT
Code:
[email protected] ~ $ adb devices
List of devices attached
015c7d7a445c260c recovery
Then lets push the bootit.ko to the root of the device like this
Code:
adb push bootit.ko /
OUTPUT
Code:
[email protected] ~ $ adb push bootit.ko /
673 KB/s (27690 bytes in 0.040s)
Then lets insmod this .ko file
Code:
adb shell insmod /bootit.ko
This should reboot the tablet into the bootloader menu, lets verifiy.
Once in the bootloader screen lets make sure your PC can see the device in fastboot.
Code:
fastboot devices
OUTPUT
Code:
[email protected] ~ $ fastboot devices
015c7d7a445c260c fastboot
So now its time to erase the misc & cache partitions, as that is most likely the partitions that is making it boot to recovery...
Code:
fastboot erase misc
OUTPUT
Code:
[email protected] ~ $ fastboot erase misc

******** Did you mean to fastboot format this partition?
erasing 'cache'...
OKAY [ 2.096s]
finished. total time: 2.096s
Once these two command run with OKAY as the OUTPUT .
It is time to make sure we can reboot into the bootloader with the hardware buttons
So from where you are at in the bootloader screen use the VOL DOWN & POWER buttons to boot the tab back into the bootloader screen ..
Run these command in fastboot in this order
The next command is to just verify your computer can see your device
Code:
fastboot devices
OUTPUT
Code:

A message from _that
_that said:
Here is the original thread where the bootit module was tested for the first time -> http://forum.xda-developers.com/showthread.php?t=2291974
The problem was that the installed recovery was too old and incompatible with the bootloader and so could not access the eMMC at all. The bootloader command to boot to recovery is stored in the MSC partition (mmcblk0p3), and the recovery could not clear it. Since the bootloader checks the MSC partition before checking for volume-down, it is impossible to get to fastboot without some additional kick in the butt (aka "bootit.ko").
The correct bootit.ko file to use is the one in "bootit-bootloader.zip": http://forum.xda-developers.com/attachment.php?attachmentid=1985941&d=1369339132 - the older version turned out to be too weak. Note that this is a zipped kernel module, not a recovery-installable ZIP. You need to unzip it on your PC before adb push.
After making it to the bootloader menu and working fastboot, you can fastboot flash a current version of TWRP and install the custom ROM of your choice. No real need for the stock blob, unless you want to make sure you have the current bootloader and a known working ROM.
Here is another thread where bootit.ko didn't help, maybe it was really a hardware problem. But lots of good background info from me. -> http://forum.xda-developers.com/showthread.php?t=2437376

Azpen A729 fastboot interface

For those of you who have inter-connectivity through ADB with your Azpen A729 , but have lamented that fastboot seems not to work with this device, listen up. Please note, however that I will not be responsible for what you may do to your Azpen tablet whilst at the fastboot command line. From there you're on your own.
It's all quite easy. This Azpen tablet presents itself with USB vendor id 1f3a to your PC. Surely you're aware of this already as you've been communicating with your tablet through the ADB shell and have included something similar to SUBSYSTEM=="usb", SYSFS{idVendor}=="1f3a", MODE="0666" in your udev rules. Oh yeah, remember that... {idVendor}=="1f3a"? It all comes back to you now. All you need to do with fastboot is to explicitly identify the USB vendor id as 0x1f3a on the command line. Let's give it a try:
First put the Azpen A729 in bootloader mode:
Code:
# adb root
# adb reboot bootloader
Have a sip of coffee.
Now invoke fastboot with the following:
Code:
# fastboot -i 0x1f3a devices
Android Fastboot fastboot
Notice now that your tablet responds as an Android device in fastboot mode and all fastboot command-line arguments are available to you. Please be careful. May I suggest this one:
Code:
# fastboot -i 0x1f3a continue
resuming boot...
OKAY [ 0.009s]
finished. total time: 0.009s
That simply continues the boot process and you're back to normal on your tablet.
Once again, please be careful. Be safe. You've been empowered.
- PoFolk
How do you unlock the Azpen A729 bootloader?
Again, this is quite simple. You must do absolutely nothing. The Azpen A729 tablet ships with the bootloader unlocked and with the super user (su) binary enabled. Here is the fastboot response from my unrooted, stock Azpen A729:
Code:
# fastboot -i 0x1f3a oem unlock
...
FAILED (remote: system is not locked)
finished. total time: 0.016s
Now if you are adventurous, skeptical, curious, or all of the above and need further "proof" that your Azpen is already unlocked, you could very easy toggle its bootloader status with the following command. HOWEVER, I suggest that you firstly backup your user data as you'll want to unlock it again and in the process of toggling between lock and unlock the user data will be wiped. Still want to do it? Here ya go:
Code:
# fastboot -i 0x1f3a oem lock
...
OKAY [ 0.016s]
finished. total time: 0.016s
Now your Azpen is locked. To unlock it again simply execute:
Code:
# fastboot -i 0x1f3a oem unlock
...
OKAY [ 10.707s]
finished. total time: 10.707s
Notice that it took a little more than 10 seconds to unlock. Why? Your user data was being wiped, but not-to-worry. You backed it up before running this experiment.

Have you tried flashing a backup of your system img yet?

Kindle fire hdx 7 starts in fastboot mode wrong boot/corrupted recovery image?

Hey all i ran into a problem yesterday i downgraded my fire hdx tablet to 13.3.2.8 and everything went fine except that my boot image and recovery partitions got messed up so now when i turn it on it goes straight into fastboot mode i have the 32 GB model 2013 edition which is a 7 inch thor based tablet i heard someone was able to flash fastboot via linux but i cant get it to work on windows 7 64 bit so im going to try flashing a new boot image and recovery partition via linux to see if that will fix the problem but i would appreciate the assistance. Thanks

There is no known (or at least widely recognized) recovery from a catastrophic 3.2.8 boot failure. As the bootloader remains locked (and hence fastboot crippled) I do not believe you will have success restoring recovery or flashing a new boot image. Sorry - I'm afraid you now own a brick.

Believe response would be similar regardless of host. With a locked bootloader only a few fastboot commands work - none of them useful. Maybe you'll find a workaround!

Can't unlock bootloader versions >3.2.3.2; can't flash with a locked BL. Your device is bricked.

Unable to boot to FastBootD

My phone does not enter into FastBootD mode when I enter "fastboot reboot fastboot"..
The screen on my phone doesn't change at all when I enter the command, and my computer adb window reads the following, it's some sort of help menu;
Any advice? Thank you it's very much appreciated.

SDK Platform Tools release notes | Android Studio | Android Developers
Android SDK Platform-Tools is a component for the Android SDK.
developer.android.com
You need to update your adb/fastboot. Download the latest platform tools from the link above.
That seems a bit odd since I just downloaded it 2 days ago from Google! Could have got an old link but I doubt it...
Didn't work unfortunately!
I downloaded the zip file from the link, unzipped with 7zip and got "platform-tools_r30.0.5-windows". Within there is a folder named Platform Tools.. I held shift and right clicked on the white space in that folder and opened a powershell.. Ran this:
PS C:\Users\CSW\Downloads\platform-tools_r30.0.5-windows\platform-tools> fastboot devices
ZY227FVPN4 fastboot
PS C:\Users\CSW\Downloads\platform-tools_r30.0.5-windows\platform-tools> fastboot reboot fastboot
usage: fastboot [ <option> ] <command>
And received the same help menu and no change on my phone.. Same result.
Listen.....reboot to recovery. It's an empty barren wasteland, until: hold the power key down for a 3 second count, now, continuing to hold the power key down, hold the volume up key down for a 2 count: 1, and 2, and...release.
On the new menu enter fastboot - this is fastbootd.

hold power an hit vol-up once then release
The trick for our SOFIA is to execute the ADB command while the phone is POWERED ON (System booted up like normal - like when use the phone, make calls, etc) and NOT in fastboot/bootloader mode:
Enable USB Debugging in developer options on phone
Connect USB cable
Answer confirmation/security prompts on phone and PC
Type "adb reboot fastboot" at ADB CLI
FASTBOOTD will now appear in red letters at the top - you are in FASTBOOTD mode
Hope this helps!
