I have installed Crdroid Nougat ROM to my LG G2 D802 yesterday, everything was fine. After flashing something via recovery phone went dark. When I boot device it shows only LG logo with secure booting error, then the screen goes black while phone is still on. Download mode and recovery wasn't working. When I plug to usb computer was going crazy with device errors. I tried a lot of solutions like this , with ubuntu and windows 10. Nothing worked for me. After a few hours I found a simple solution in a forum. Worked for me, maybe work for others..
Press Power and Vol Down buttons together for about 10 seconds, When you see LG logo release for a half of second and immediately press and HOLD again Vol Down + Vol Up button. Factory reset screen will come. Select yes with vol down button and press power button to factory reset.

A boot loop happen after i tried installing cyanogenmod 7 early realease from this forum. Now the device stuck in boot and will display cyanogenmod 7 blue circle around 3 -4 seconds over and over. Can anyone of you help me because i think i need to do a factory reset, but now it stuck in boot loop and it does not have a key combination to go into recovery mod. Help

There is a key combination. Search it on google. How to boot lg optimus (your model) into recovery. Once in wipe data then wipe cache
Sent from my Nexus S using XDA App
Expansion
From searching other forums and google I found the following:
You can enter update mode by removing the battery, then while holding down the VOL + button plug in your usb cord(i assume while it's connected to your computer).
Then you can search the forums here and find:
[LG P970] Upgrade Kit 3.5
(the title is longer than this i just didn't put it all in here due to laziness)
This should help you in your quest of retrieving your phone from light up paperweight status. I don't really know though. Since I've never used your phone. Good luck.
recovery mode
you need to press the home button,volume -, and power,
to enter to the recovery mode.
sorry for my bad english.

The Home key is actually the touch key on the Optimus Black..it's not a button but a touch input
The combination is the same as above :good:

Doesn't work when you power up your device with those keys.
Power on your device before you press the key combination.
Took me a frustrating half an hour to find out...

power up your phone, when the buttons start to blink (or the cm logo appears or whatever boot logo you have) press and hold vol down then press power button (home key is not really needed like the video ) . it also works on stock rom if you have a recovery installed.
note that it won't work at the early bootup when the lg logo appears or when android is booted and ready.

It takes me in safe mode, i'm not even sure what it is (I guess is something similar to window's? It has less apps when I am in safe mode!
I'm not sure what to do, I tried to reboot in recovery mode with the ROM manager but it doesn't work (nothing of the ROM manager works actually).
Any ideas on what safe mode is?
Thanks!
UPDATE:
I tried this app to reboot in recovery mode
play.google.com/store/apps/details?id=com.siriusapplications.quickboot&hl=en
It rebooted the phone, the android robot showed up with some stuff turning in the stomach (like this: upload.wikimedia.org/wikipedia/commons/7/76/Android_Update_Screen.JPG) and then it turned on normally except that all my data now is gone (which is not a problem since I wanted to wipe it from the recovery mode, the problem is that I still can't get into recovery mode!
P.S.: it wouldn't let me post normal links because I'm a new member, I hope I didn't break any rule posting them like this! (after all it's not spam!)
I have new galaxy tab 10.1 which I am planning to root, however I cannot get unit to enter download mode. I have tried unsuccessfully at least 20 times using the recommended method of turning the unit completely off then holding the vol-/power buttons. I press the vol- slightly ahead of the power button and hold. All I get is the samsung splash looping over and over with no download or recovery menu icons popping up after the samsung splash. Once I let go, the tab will go into android recovery mode with the option to reboot which takes me to where I started. I have followed all of the tutorials to the tee. Is there another way to get to download mode? Should I take it back if this indicates a more serious problem.
I have also done a factory wipe/reset to no avail. Will vol+ / power do anything?
thanks for your interest I would appreciate any help.

I seem to recall that at least one variant swapped the button around. In any case, it can't hurt to try volume up.
Here's what you do - first, shut the device off by holding power down and waiting for the confirmation.
Then, when it's off, hold the volume down button (to the left side, next to the power button.) Holding that down, press and hold the power button. When you see it light up, release the power button but continue to hold volume down until you see the recovery/download icons.
If doing that doesn't work, try volume up and power. Good luck!
Ill try your suggestions. thank you

I'm having a similar problem. I have a galaxy tab 10.1 wifi that I rooted immediately when I got it. I havn't used it in about 4-5 months. I've already done all the odin and download stuff, but now i want to update my cwm and install a JB rom (I'm currently using aokp). I'm having a funny problem with it now -- Its difficult to turn on and impossible to get into download mode.
In order to turn on my tab, I have to hold down the power, connect the charging cable and get the download screen to turn on, then hold down the power again, wait for the screen to turn off, unplug the power and hold the power button until hopefully it turns on again. And this doesn't always work, sometimes I have to do it a few times. But whenever i've tried do the same thing that gets the tab working normally -- only holding the down volume as well as the power, Nothing happens.
Now once its on and working, things work great, but turning it on is a pain and its impossible for me to bring up the download or recovery option.
I've also tried to 'reboot to bootloader' and that doesn't work, although i can still 'reboot to recovery'
Any tips?

I have almost the exact same problem...
Volume up puts me into download mode and i can connect with Kies but it wont do the JB update
Voulume down ... nothing just boots
if i let it try to do the OTA update it will freeze at the boot screen and stay that way till the battery dies.
To get it to work again i have to do almost exactly what was decribe above..
I have no recovery options at all.
also my Tab is "NOT" rooted

I had a similar problem initially... the screen would just flash the "downloading" message, but the tablet wouldn't mount/connect to my laptop. Here's the solution:
1) launch odin
2) connect usb cable to laptop only
3) power down tablet
4) hold down the power volume down buttons together
5) when you see the downloading message, let go of the power button
6) let go of the volume down button (now just displays "downloading" message, but nothing happens
7) press volume UP
8) you'll get a message about installing custom ROMs and be given the option to do so by pressing volume UP again
9) the tablet mounts and connects to odin
10) from there follow the instructions for flashing recovery via odin (i.e., using PDA button...)
FYI just double check the guides again regarding download and recovery modes. In the thread title you mention Tab 2. This is the forum for the original Tab not the Tab 2. Both devices have different methods and key presses to access the various modes.

1.Completely shut down the device(by pressing power down button for about 20s)
2.Try the Power + Vol Up combo again(keep them pressed until amazon logo disapears)
3.If you don't see anything, try twice or thrice again
If you are finally able to get access to TWRP, then follow my instructions here :

HELP! Blue Wave 8 33GT tablet stuck in recovery mode with "No command" message
I got my Blue Wave 8 33GT (not HD+) tablet completely bricked. First of all, I know this is not really a popular device and some of you might not have a single knowledge about this one, but I hope in any way you might help me get this device working again. Thank you in advance!
Some info about this device:
Bluewave's website: Wave 8
Android OS version: 4.4 KitKat
Device processor: Rockchip-based (RK31)
What just happened? It suddenly reboots while I'm playing and gone into recovery mode with an Android and a "No command." message. Now it won't boot the system anymore whenever I reboot, it always going into this recovery mode.
It has no volume buttons, just a reset, a hard back button and power button. Holding down the power and back button goes into the recovery mode directly. Through normal boot, it flashes the Bluewave logo twice then goes into the recovery. While the reset button immediately turn the device off. There's nothing else I can think of that I can do in this case.
My laptop can recognize it as an ADB Device in recovery mode and I think I may be able to flash it via Rockchip BatchTool, but the instructions I've read states that the device should be up and with a USB debugging enabled which I am not currently able to do in recovery mode. Device is rooted and working totally fine until this happened.
Anyone got into this kind of problem and able to go through it? Please, any help is greatly appreciated.
P.S
Just let me know if there are any additional info I could give you.

Hey! Thanks for your reply and time.
I tried every combination of either of the two keys but there is no such recovery menu showing up, and I am pretty sure that this device doesn't have a built-in recovery for factory reset.
If only I could go to its download mode stuff to be able to flash the firmware...

"Long press the power button to restart the device. If restarting fails, hard reset the tablet by poking the Reset hole using a pin. " it is from FAQ
maybe this could help.
1. Press the power button to get the option menu for
Power off
Reboot
Silence phone option.
2. on that menu you have to hold down that power off option on your touch screen while also holding down the home push button on the side of your tablet.
3. This brings up a screen to reboot into safe mode..(these are the 3 steps the company does not tell you that is why no one gets it to work.
4. HIt yes for safe mode and then hold down your power and home buttons on side of tablet till the dopo Logo appears.
5. Release both buttons and hit the power button one time and then hold only the home button down till a menu option appears.
6. Use the home button to move down to factory reset and press the power button to select. Once it says complete then use the power button to select reboot.
Problem solved. Hope this will help everyone out.
The only way is to remove the battery, attached again the battery then power it on their is no hard reset on blue wave the go to settings factory reset
Old LG G5 I had previously installed Lineage on. Was in a drawer until I decided to charge it up and let one of my kids play games on it. When I input the correct screen lock pattern, it goes black, then comes back to lock screen.
I am able to hold power button to then select power off, restart, etc. From power off, I power on and get the orange triangle recommending to lock the bootloader. But no combination of power and vol-down or power and vol-up will get me to TWRP. It just rolls right back in to Lineage.
Also, from power off, if I plug in to my Linux laptop, it will power on and go to fastboot.
Feels like USB debug got turned off and/or trust somehow got revoked, but I never had this laptop connected to it so probably doesn't matter. But like I said, my unlock pattern is working. I get different response with correct pattern versus incorrect.
I'm also able to see the phone from my https://google.com/android/devicemanager page. I tried to send a secure and erase thinking it might let me start from scratch, but I only see a notification that "Device Located" and it never does anything.
And finally, lsusb -v does see the phone, but adb devices never does.
My question is any idea how to get back to TWRP to wipe and push an updated image or even put an updated TWRP?
Try this ...
It's like getting into Stock Recovery. To get into TWRP Recovery using button combination (hard reset) you'll need to hold volume down button and power button simultaneously, releasing power button (temporarily) once LG logo appears then quickly pressing and holding power button again, all the while maintaining hold on volume down button. The stock recovery message (white background) will appear requiring you to select volume up/down button to continue to reset software (see attached image). If you select yes it will appear to factory reset but will actually boot into TWRP.
Hope that helps!
