Vol- plug in USB is fastboot mode.
Vol+ plug in cable is download mode.
If you stuck in fastboot mode to get into download mode:
(Hold vol-, power, vol+ all 3 together until phone goes blank immediately release vol- and power keep holding vol+ it should boot into download mode )
doesnot work for me faild cannot erase this partation in unlocked state
doesn't work it says my phone doesnt pass a safety check and not will boot, and after that goes to fastboot
After unlocking the bootloader LG G7 run Android 10 by QFIL, I got stuck in fastboot. I consulted many sites but could not find what I needed.
I would like to share some of my experiences after I have successfully fixed them.
Once you have unlocked the bootloader you have illegally modified your phone. When something goes wrong, the phone automatically stops at fastboot. If you want it to continue, you need to load the magisk patched boot.img.
The boot.img can be extracted from your kdz rom file and you can make the patched boot.img by magisk app on the other phone and flash to the boot_a and boot_b partition by QFIL
After successfully boot your phone with magisk patched boot.img, you must use LG Bridge to refurbish your phone (choose Refurbish Option when flashing your rom) to make sure it work fine.

Flashed Build HWI69 for US Retail on a Canadian wifi MZ604 xoom..tired of
waiting for 3.1 update.
adb reboot bootloader
fastboot oem unlock
adb reboot bootloader
Xoom will then reboot into bootloader screen
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
fastboot reboot
It is stuck on Starting RSD mode 2.
I can not get it to fastboot protocol...device does not turn off.
Any solutions?
Fastboot OEM lock is where you went wrong. Anyway see this thread.
OK I did this procedure yesterday but did not relock (I know it says to on the moto site but the guide I read said not to).
Anyway, pressing power and vol up will force a reboot. Unsure what will happen when it boots back up though...!
You should be fine. Only trying to relock will cause this error.
To get back to fastboot after a bad lock do this.
Power button and volume up, this will reboot the device.
As soon as the screen turns back on holds down power and volume down. In about 60 seconds your device should go to fastboot. Do not let go until it gets there.

Thanks for the reply . It now says Failed to boot LNX 0X0004
Starting Fastboot protocol support
However it will not connect to xoom.
<wait for device> when issue fastboot command.
What the hell is going on?
you need to read this thread
http://forum.xda-developers.com/showthread.php?t=1108518
The exact thread I linked to...(-__-)'
I followed instruction from motorla dev support site.
"h**p://developer.motorola.com/products/software/?pubid=987654"
It uses command "fastboot oem lock"! So why did locking brick the device?
here it is:
Device Software Images
Select the appropriate device software image to download and re-lock your device. If you need to find your build number on your Motorola device go to Settings and About Phone or About Tablet.
The commands to flash and re-lock your device are as follows:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
Note: If no userdata.img file is present in your download, please issue the command:
fastboot erase userdata
The Moto instructions are for locking the device back to it's own image. You are not using your device's own image. Every guide I've seen on here tells you not to relock, regardless of what Moto say. Believe the devs.
Thanxs
I now believe the devs......
Thanks for the reply. Sent the beast out to moto Canada today.

Try making or obtaining a factory cable which its different from an OTG cable. Start with the two links below. This might save the day.

I tried to root my Motorolo Xoom 3G however after appliying fastboot reboot commend the device stays at the screen where Motorola logo and Dual core technology are.
The device is not responding any commend that I applied via PC.
I am able to enter fastboot protocol.
Here are the commends that I applied.
1 - adb reboot bootloader
2 - fastboot oem unlock
3 - fastboot flash boot boot.img
4 - fastboot reboot
After I applied all these commends , in MsDOS screen there were fihished text.
What should I do to start the device system again?

You can manually reboot by pressing volume up a power and holding until it reboots, then when you see the red dual core screen tap volume down and then volume up. You should be back in 'starting fastboot protocol' again. Make sure you have actually unlocked. Try fastboot oem unlock again and if it gives you instructions on the Xoom screen, follow them all. It should reboot into the os...skip all set-up steps except go into settings /applications/development and make sure debugging is checked. Then reboot back into fastboot and continue with what you are doing.
I unlocked it again however still it stucks at the Dual core screen. Is there any other operation to start the system.
By the way, I am using a Turkish version of Motorola Xoom 3g. I guess it is an important detail.
I have resolved the problem.
I downloaded MZ601_H.6.1-38-11_Retail_Turkey file from motorolo developer web site.
Fastboot flash boot bot.img
Fastboot flash system system.img
Fastboot flash recovery recovery.img
Fastboot flash userdata userdata.img
Fastboot erase cache
applied the above commends.

Hi. Huawei p8 max dav703-l phone owner. Phone is using kang vip b211. Downgrade to kang vip b029 phone is now Huawei Logo stuck. No opening. Please help?
So first you need the following.
1. Clean B029 firmware.
2. Huawei Firwmare Extractor
3. ADB and fastboot
4. P8max TWRP
After you have all those.
1. Locate your Update.app from your B029 Firmware.
2. Use Huawei Firmware Extractor and extract the follow from your Update.App
boot.img , recovery.img, cust.img , system.img , cache.img , userdata.img
3. after rename all the files you have extracted from Huawei Firmware Extractor ( they should be called. "10.boot.img , 11.recovery.img .... etc") to the following:
"boot.img, reocvery.img , cust.img, system.img, cache.img, userdata.img"
4. So now you need to put those files in the exact place as your ADB and fastboot. So your FOLDER should look like the following:
ADB.exe
Fastboot.exe
"some ADB & FASTBOOT files"
boot.img
recovery.img
cust.img
system.img
cache.img
userdata.img
Also, put the updates.app file into your SD card under the folder "dload". So it should look like "X:\dload\updates.app"
After you have the following setup, do the following on your phone.
Make sure your phone is shutdown.
1a. plug in USB then (vol down + power) to boot into bootloader
** If your phone can not shutdown because you are in a bootloop**
1b. Make sure you have (hiSuite) installed, plug in your USB to your computer. Hold all bottoms till the phone turns off a vibrate. Then hold (vol down + Power) to get into bootloader
2. Use command prompt to go into your setup you have done at the top with ADB, fastboot and img files.
" cd c:\your\folder\here\p8max " for example
type "fastboot devices"
you should see your devices show up. If it doesn't then you have driver problems you have fix first or you don't have hiSuite installed. (Try re-installing hiSuite)
If you see your device show up, type the following
MAKE SURE EACH "fastboot flash" SAYS OK BEFORE DOING THE NEXT STEP.
type "fastboot flash boot boot.img"
type "fastboot flash recovery recovery.img"
type "fastboot flash cust cust.img"
type "fastboot flash system system.img"
type "fastboot flash cache cache.img"
type "fastboot flash userdata userdata.img"
If all are ok, you want to:
type "fastboot reboot"
This should restart your phone. You should be able to boot up your phone. Once you have your phone boot, your not DONE YET!
Turn off your phone, make sure the B029 update is in your SD card. (see example above)
turn back on your phone and hold (vol up + power) with NO USB plugged in. This should force your phone to force update back to B029.
Make sure you get to 100%. NOW YOUR PHONE IS FIXED! - it will reboot, then now you should be in b029
If you get stuck at 90% then you need to clean up your internal storage first.
