[Q] Recovery via ADB ? - LG Optimus Black

Is there a possibility to enter stock recovery via USB cable and ADB in SW Upgrade Mode?
Can anyone check this as my phone is in repair centre?
1. Turn off the phone
2. Connect USB cable with Vol+ button (phone enters in SW Update mode)
3. Open command prompt and from ADB folder type "adb reboot recovery"
4. Is this working?
I'll be very grateful if someone would check this. Thanks in advance.

Please, it is very urgent. If it works I could today pick-up phone from my Operator before they send it to repair. They're sending it tommorow.
Much thanks and sorry for double posting...
EDIT:
@fjsw: thanks for checking.

No it doesn't work
output:
error: device not found

I'm in recovery...
I turned on my bricked OB, waiting for bootloop, plug USB and "adb reboot recovery"
Sorry for my bad english
edit: I inserted some files from Nova v8zip to CM7-SelfKANG4.zip and flashed this edited CM.zip... Bootloop, plug USB and "adb reboot recovery" .. but, I flashed again CM.zip, now no-edited, reboot system from recovery and i got Error sreen.. So I flash firmware with http://forum.xda-developers.com/showthread.php?t=1111771

AFAIK it doesn't work. I tried it too (when i bricked my OB {CM7-->stock} but it didn't work!

Wow it's been an "old-time" thread to reply, since the first post August 7, 2011. yet it still replied today.
AFAIK, "Android Debug Bridge" need operating system to run (to debug). It need USB Debugging that running with Android, so ADB can't run without Android OS running..

Moved to Q&A for you. Remember, all questions go in Q&A and never in development.
So have you managed to return it to stock after?

New Nexus 6 stuck in a bootloop trying to update to 5.1, please help.

Hey everyone I'm looking here as my last resort before sending my phone back to Motorola.
Bought a Nexus 6 from motorola uk which was delivered yesterday, switched phone on and all the Google apps on the phone updated, then had a notification OTA to download and install android 5.1 which I did, towards the end of the install process I had an error with the green android and a red exclamation mark.
I powered the device off with the power button and it turned back on and ever since it says "Android is starting" "Optimizing app 1 of 125" once it goes through all the apps it gets to the android boot screen then just goes back to the "Android is starting" "Optimizing app 1 of 125" over and over and over. (Infinite bootloop)
Pointers: The phone is not unlocked or rooted as I'm a noob its just fresh out the box, also I never opened/unlocked the developer options.
I have tried various recovery mode fixes, wiping cache and wiping all data and then rebooting the device with no luck.
Is there anyway I can hook my N6 up to my computer and fix this with a tool kit etc? I'm willing to try but I'd need basic instructions and reassurance it wouldn't muck up my warranty if it didn't work as my only other option is to exchange for a new device.
Any help, advice etc would be hugely appreciated. Thanks

Read the guide on how to fastboot flash a factory image. No toolkit necessary.
Would you mind posting a link to a guide? I forgot to add that I don't want my phone to become rooted by trying to fix this issue, I want to keep it stock like it was, also does not have developer options enabled stop me from going further.
Sorry for the questions I'm a noob to this and quite anxious.

I've made the fastboot adb folder on my PC and attached my phone whilst it was in bootloader mode, I types in the command box adb devices and there is no list of attached devices.
I presume this is because I didn't enable developer options or USB debugging?

When in bootloader mode type : fastboot devices
-Edit- just read that your bootloade is still locked so i`am afraid there is nothing you can do to fix the issue as you cannot flash firmware with a locked bootloader. Best is to claim warranty because of a software issue while updating.

Thought this would be the case, I went into adb fastboot and typed in fastboot devices and its showing some letters and numbers next to fastboot on screen if that helps.
In the future I presume I should make sure to enable developer options first so I can get out if this mess?
Also would it be best when I get my new n6 just to sideload the latest update marsmellow by getting the factory image from the Google website? Last question can I skip from 5.0 straight to 6.0 sideloading or do I have tobdo it one at a time?
Thanks for trying to help matey

Next time enable usb debugging and ENABLE OEM UNLOCK, both in developer options. You can flash the latest firmware available directly in fastboot by flashing the individual img files.

It says this on my Nexus 6 phone screen.
Unlock bootloader?
If you unlock the bootloader, you will be able to install custom operating system on this phone.
A custom OS is not subject to the same testing as the original OS, and can cause your phone and installed applications to stop working properly.
To prevent unauthorized access to your personal data, unlocking the bootloader will also delete all personal data from your phone (a "factory data reset".)
Press the volume up/down buttons to select yes or no. Then press power button to continue.
Yes (Unlock bootloader, may void warranty)
No. ( Do not unlock bootloader and restart phone)

Sure, but first we have to get the phone working again,

Stuck on LG screen when boot.

I tried to reboot and it is stopped at the LG screen as shown in the attach photo. I dont know what to do now, as I think it cant even connect and to the dock (still charging but not recognised at all by the PC). It would be great and very appreciated if anyone knows what I need to do? Otherwise it is an expensive paperweight now.
Thanks in advance.
P/S: This is my 1st post in XDA, so if anything wrong with my post please let me know, I will change. Thanks again.
Update
I managed to make it work again. this is what you have to do is boot it to bootloader mode, then go to recovery mode and use the "apply update from adb" function (sideload in other words) to install the Android 6.0.1 again.
Link to download Android 6.0.1.
To put the watch in bootloader mode, follow the instruction in my youtube video here.
As soon as it is in bootloader mode, your computer should see the watch as an android device now.
In Bootloader mode, go to recovery mode (use the virtual buttons on screen), then go to the "apply update from adb" option.
Now, at this step, you need to open command line on your computer and type "adb sideload <android file>", where the <android file> is the one you download earlier. You can just type "adb sildeload" then leave a space and drag the file to the running Cmd window.
Now just wait for it to complete and restart itself.
Hope this helps.
This may not help, but try pressing the side button in for 20-30 seconds. Shortly after it stops vibrating, it will start rebooting again and then you can stop pressing the button.

Hi There,
I have the same problem after the update.
I followed your steps but to enter into recovery mode I had to enable USB debugging mode which cannot be done as the watch keeps on rebooting.
Please let me know is there any other way to enable usb debugging mode to enter into recovery?
I get this error on my pc when I enter into recovery " error device '(null)' not found adb"

Any other phone if you don't flick oem unlock first in developer ootions it's a hardbrick. The Asus unlock tool apk does this. Did you install that first and unlock first? Hope you can recover

You're FUBAR for now, nobody has figured out a way to flash the phone without an unlocked bootloader. Just use it as a brick until someone finds out QDL9008 or other ways to flash it.

Your only option is to go to ASUS service center in your area and ask them to repair it. If they accept to service it they will of course charge you for it which is better than having a bricked phone. Other than that your only option is to send the phone back to China there you can claim that the phone got a bootloop and since you didn't unlock the bootloader you are still covered by warranty meaning you will only pay shipping fees.
Thank you Rashad83. I just sent it to Asus Service Center with a fee.
Did you guys changing the Boot Slot?
Check your current boot slot by hitting -
fastboot oem device-info
Then change the slot to "B" if you're currently in "A"
Slot change command -

Guys, Please obtain an ASUS Raw firmware to recover your devices. Do not fall for tricks by various users around which asks to pay for them.
Just use Google and find yourself the correct RAW firmware for your model.

Hi, I've managed to unbrick my ROG Phone II Tencent Edition 8/128 with a locked bootloader having "slot _a" error. Link to other thread: https://forum.xda-developers.com/rog-phone-2/how-to/repair-rog2-phone-edl-modeofficial-t4012175
My equipment for flashing, for sure you already have ADB installed in your computer, my computer is an x64 Intel Windows 10 laptop, I used USB 2.0 not USB 3.0
Credit to @johnny886 for the sharing the tool,
"If your phone can only enter EDL mode (9008 mode)
this firmware is glad to help you. It can be flashed in through
the QPST tool, or it can be flashed in through the Xiaomi miflash tool.
To use the QPST tool, you must change the EMMC to UFS. No matter which tool you use, -(I personally did not use this, I just downloaded the file and followed grewookie's instruction below)
you must restore the factory settings after the phone is turned on, otherwise the storage
of the phone will recognize the error! !! !!
Factory settings must be restored after booting! !! !!
The firmware is made through the official package UL-ASUS_I001_1-ASUS-16.0631.1910.35-1.1.207-user.zip
without any modification, Suitable for repairing phones that can only enter edl mode(9008 mode).
File Downlaod link: https://drive.google.com/open?id=1Pk...Sf6cDq7SuJiBBu"
Credits to @greywookiee for the super clear instruction:
"Here's some instructions I put together that would have helped save me a lot of time. Please correct anything I missed:
After you have downloaded the zip file, here are the step-by-step instructions:
1. Extract the zipped folder wherever you want on your PC.
2. Open a CMD window.
3. cd /d <whatever path it is to the "\ASUS_ROG2_ZS660KL_QPST_Firmware\images" folder> e.g., "cd /d D:\RogPhoneII\ASUS_ROG2_ZS660KL_QPST_Firmware\imag es"
4. Make sure your PC is connected to the side port of your phone and the phone is in fastboot mode (Volume UP button + Power button).
5. Check and make sure your PC is connected properly by entering "fastboot devices" in the command window. You should see the ID of your device.
6. Then enter "fastboot oem enter-dload" in the command window. This will put the phone in emergency download mode (EDL). My phone went all black.
7. Open "\ASUS_ROG2_ZS660KL_QPST_Firmware\MiFlash2018-5-28-0" folder. Launch "XiaoMiFlash.exe".
8. Click "refresh". You should see a device in the list.
9. Click "select" and navigate to the "\ASUS_ROG2_ZS660KL_QPST_Firmware\images" folder.
10. Click "flash". Wait until it says "success".
11. After it's done, you'll hold down the UP button, Down button, and Power button on the phone at the same time until it shuts down.
12. Hold Up button and Power button at same to boot into fastboot mode again. Select Recovery mode by using the Up/Down buttons on the phone. Press the Power button to select.
13. Select "wipe data" from the drop down list. Go down the list of "no" until you get to the "yes" and press the Power button.
14. Select "reboot now".
15. Done."

Right now I'm getting slot_b is unbootable. My computer recognizes the phone as "Android Bootloader Interface" but when I run "adb devices" it doesnt show up and I cant run fastboot commands even though I'm plugged into the side usb port. Please help me.

Was the boot img rooted, is that why you have no recovery? If so, just boot to fastboot mode and flash stock boot instead of root, that should have recovery

Download the Full Rom
Extract it
Use the exe file to install with bootloader screen
Ok that was able to get me back to recovery, I tried to wipe and then boot into android, didn't work got the "your device is corrupt and cannot be trusted and will not boot". Still isn't recognized in adb devices so I don't know how I would proceed from here. My device is the Tencent Edition if that helps with raw firmware/rom.
P.S Thank you guys so much for your help I really appreciate it.

But you get fastboot mode, just plug the USB in side port and flash latest raw WW Rom.
Here's the link to 1908.21

Once in fastboot mode (the first menu you see, before selecting recovery, start, power off etc is fastboot mode) check your device is recognised with fastboot devices cmd and then run flashall_AFT.cmd that'll get back your working rom . But also, delete or move the original zip from that same extracted folder, the raw rom with the same name confuses the flashall_AFT.cmd
So I flash the most recent firmware you linked and double checked in recovery that it was pushed to the device and it was, but when I try to boot into android I get the asus logo for a second and then it restarts and it will give me a screen that says "Your device is corrupt. It cant be trusted and will not boot" and then has a link to google support .

Did you let the raw rom flash entirely? It should take a minimum of 10 minutes... The phone should reboot twice (I think) as it completes... Maybe try again, but I'm not familiar with that message...
If the phone doesn't reboot, I would let it run for a half hour or so before rebooting...
There we go, I got it to work man, I was just being impatient with the firmware flash but now I got it to work I appreciate your help and patience so much let me got through and thank your comments and then you can flag a mod to take down this thread. Thank you
