[Q] How to enter fastboot mode in LGC800 (myTouch Q) - Android Q&A, Help & Troubleshooting

My mom's LGC800 is stuck in LG boot screen, is there any possible way to enter fastboot mode in the LGC800? I tried the adb command "adb reboot bootloader" it reboots and gets stuck again in LG boot screen... Any button combination? Cause I badly want to unbrick it...

I have adb and fastboot. I rooted with SuperOneClick.

I can not reboot in recovery
II tried these steps:
Adb reboot bootloader reboots but stops at the LG logo.
Same with volume – plus A plus F then Power on. I let go the power on after 3 seconds.
All I get is LG logo.
In Rom manager and recovery mode. I get the Lg logo.
The only way to come back to my phone is to use fastboot reboot.
With a terminal emulator, Command SU, command reboot recovery. The phone reboots but stays on the lg logo.
I tried fastboot reboot-bootloader and I get the same LG logo.
I downloaded and tried Quick boot app in recovery and and I get the same LG logo.
Is there a way to see if there is a recovery application on my phone.?
Can anyone help me to reboot in recovery?

[Q] Stuck in bootloop, can't connect to adb

I tried installing CM12 and when I restarted I got stuck in a bootloop. It just stays on the LG logo screen for a while until the kernal crashes. I can enter Dload mode and fastboot and I see my computer installing the drivers but adb devices says nothing is connected. I tried entering recovery but the phone just vibrates, restarts, and goes back to the LG logo. Is it fixable or do I have to send it in for repairs?
*Edit* - After about ten minutes of trying to enter recovery and rebooting it finally entered recovery and now all is good.

HTC OneX+ Doesn't Start (Stuck at htc Logo) & Can't Enter Into Recovery Mode

Hi Everyone,
This is my first post here. I don't have much idea about android systems so posting here.
My friend has some booting issue with his HTC OneX+.
The phone is not starting up (Stuck at boot- time HTC logo) and we are not able to enter into recovery mode using Volume Down Key + Power Button.
I want to know if its somehow possible to flash the complete device and install fresh android remotely using USB without entering into fastboot mode / recovery mode.
Thanks in Advance.
hi there, if you boot the phone into fastboot you can reflash recovery, after that you may need to adb sideload the rom and reflash the kernal

[HELP]Huawei Y635 fastboot&rescue mode loop

Hi,
I have a problem with this huawei Y635, when I power on, the smartphone do always de same loop: Huawei Logo, a blue screen(but during a very few seconds), black screen, and then repeat... Unless I press Volume -, then it starts the FASTBOOT&RESCUE MODE, with the white screen, the android logo and in red letters PHONE Unlocked.
I tried:
1. With an UPDATE.APP, extract the boot, recovery and system .img, and with the fastboot, runing through the windows console, flash the three files and reboot the phone. Conclusion: Again, loop or fastboot&rescue Mode
2. Install the TWRP custom recovery using the Install-Windows.bat. Conclusion: Again, loop or fastboot&rescue mode
3. Download from huawei official website the original software and with the command "fastboot update"update.zip", try to install this official image. Conclusion: Again, loop or fastboot&rescue mode
So, please, I need any kind of help to terminate with the loop, it doesn't matter if I have to install a custom recovery or ROM..... But before install and loose all data, is there any possibility to find the contacts, the media, or any kind of file in the phone storage through the console or fastboot??
Thanks

Oneplus 6 TWRP Install Trouble

When in fastboot mode, I run the command prompt <fastboot boot boot_op6_ob3_twrp.img> however rather than booting to the TWRP recovery mode, it just goes into the screen that is the oneplus logo and says fastboot mode. When I boot into recovery mode witgh volume down and power button it goes into the advanced reboot, and then if I go through the menu and choose to boot into recovery mode, it just boots back into the advanced reboot menu. Anybody have an idea of whats going wrong? please bear with me, I am a newbie and haven't attempted rooting a phone in years.
I am using the oneplus 6 root guide on android soul website for instruction
