Force turn off Lenovo Vibe P1 - Lenovo Vibe P1 Guides, News, & Discussion

We all know how to force restart Vibe P1 which is by holding down the power button for 10 seconds..
But say you're in a boot loop or a forced recovery or a diagnostic mode and you want to unbrick the phone using Qfil..
Now you can wait for the phone to completely discharge and it will turn off by itself..
But I found another way by accident..
Steps:
1- hold both power button along with vol down button for 10 seconds to make the phone restart (this works anywhere.. in Android or recovery or bootloop) and don't remove your fingers
2- keep the buttons pressed while the phone is restarting it will boot to the green "Lenovo" logo and after a second it will power off.. you can lift your fingers now
3- now you can hold volume up and connect the phone to PC to flash stock rom with qfil or hold power and volume down to go to qualcomm test mode or hold power and volume up and down to go to recovery..
Please test if it works for you.. I tested it on my P1a42..
In Lenovo P2 it goes a little differently..
1- Do step 1 from above.. keep the buttons held when restarting until you see a black screen saying "AP fastboot flash mode"
2- Press the vol down button once until you see the word "power off" on screen.. press power and the phone will turn off.
3- Proceed to step 3 as above

Tested and working!!
Thanks for this one adhammagdy.:good:
I was stuck in a bootloop and this one helped me turn my phone off and I successfully flashed with qfil to restore my phone.
Just a quick addition for clarity...
After step 4, the phone kept bootlooping even after the volume down and power buttons were kept pressed.
Once we reach this stage, we need to release both the keys simultaneously when the screen goes dark in between. Then the phone will stay turned off and we can proceed as given in step 5.

[Q] Help! Cant get my phone into recovery mode

Ive tried the volume down and volume and power but it wont work.... Any suggestions?
You are sure your phone is off and you:
Hold down the volume up and down with your left thumb and make sure there is a click feeling from both buttons and use your right hand to click on the power button?
I'm having the exact same problem. Have tried about 25 times to boot into recovery. Just does not work.
Pull the battery after every failed attempt took me about 2-3 tries. Before you do anything shut off phone pull battery then attempt to boot into recovery.
Yes, I'm doing that. The samsung screen comes up and if I release the buttons it does the normal boot up. If I keep holding the buttons the black screen with "vibrant" keeps coming on and off.
So far I discovered that it works perfectly if you hold the power button until after the Vibrant logo appears and then release the power button while still holding the both volume buttons. If you release the power button before the logo appears it will FAIL.
Only after the logo dissapears you can release the volume buttons.
In other words:
1-Press and hold both Volume buttons
2-Press and hold Power button
3-After Vibrant logo appears release Power button
4-Wait until Vibrant logo dissapears and then release Volume bottons
5-You should now be in recovery
Pito
Wow, I followed your directions step by step and still no luck! I wait till I the Vibrant logo to dissapear to release the volume buttons but it just boots up like normal. Thanks anyways! Is there another way of rooting my phone?
What I do as well is hold until the first logo dissapears and as soon as the second one appears release buttons. Then its in recovery.
Ive tried everything you all have said so far and I still cant get my phone into recovery mode. I was able to do it on my wife's vibrant but not on mine. Any suggestions?
Try getting quick boot from the market. It had an option to reboot into recovery. If your problem is just getting the button push right (i had real trouble with it at first) then this should work.

ROM: Stock
Recovery: Clockwork 2.5.0.4
If you are rooted then Clockwork Recovery Mod has the ability to boot into recovery mode. Or you can turn on usb debugging and use adb. Start>Run>cmd and use "adb reboot recovery"

Hardware button boot into Recovery with TWRP

Sorry if this post is redundant, but the methods I've seen haven't worked, so I can't be alone. Here is how to boot into TWRP if your phone is boot looping/soft bricked. (info pulled from here, of all places.)
1. Make sure phone is completely powered down.
2. Press and hold the Volume down button and the Power button.
3. When the LG logo is displayed release the Power button only then immediately press and hold the Power button again.
4. Release both buttons when the Factory Hard Reset screen displays.
5. Press the power button three times, like it says. Even though it says it will delete everything, it won't (I can confirm that if you are at least on v2.6.3.2).
6. After a "factory reset processing" appears, you should get the TWRP flash screen, and you are good to go.
Hope this helps someone besides currently frustrated me.
I LOVE YOU! I honestly didn't think this would work but it does and i'm so happy.
just about to make a thread asking how to do this. Glad I searched. way to make you jump through hoops tho.
thanks for this. for me the phone didnt even have to be completely powered off.
i wa sin a sleep of death so i held down power and vol down until lg logo appeared let go and then pressed power again. pressed power 3 more times and it booted into recovery

Awesome. Didn't know this!
Thanks
@jadengore : I was stick in a bootloop, and your thread helps me a lot !
Big thanks !

Also, if you're too scared to try that, I've had success using rom toolbox to reboot into recovery. Of course this is assuming you have a working system.
Thanks very much, but...
Hello,
I unfortunately dropped my VS980, cracked the screen, and the digitizer only works on the bottom portion of the screen. I have a new screen coming, which should fix this issue, however I would like to get my data off my phone (pics), but I can't as I have a password (draw a line/shape kind) and without being able to enter this in, it will not connect to my PC as mass storage.
I was hoping to be able to boot into recovery with hardware buttons and get my data that way, not sure if that is possible either, but at least try it. This I found to work to get me to the factory hard reset screen, but I am skeptical to push the power button and have it wipe my data!
I am open to other options to get to my data if anyone has any, including android device manager which is something I have thought of, but not sure if I can reset the security to nothing, or maybe as the bottom portion of my digitizer seems to work, I can enter in a space or a period for a password and enter that in.
Looking for any guidance!
Thanks!
Got it!
Redid the password with android device manager, which got me in, but I didn't even need to do that as I had the brainwave to plug a mouse in with a usb adapter. Works flawlessly, got my data, now just waiting for replacement screen!
Strange Problem
I am using F-320K[G2], Cloudy G3 Rom, when I hit boot into recovery it does bring me to TWRP but hardware buttons doesn't work. It just restarts the phone.
Vol down+Power till LG logo up, release and press and hold again and after few secs it restartsand came back to LG screen. If I continue to held it it just repeat restating.
hardware keys to enter recovery. voldown+power then volup+power

steps to enter recovery that worked for my Sprint LG G2 on ZVC firmware.
1) hold power and volume down button till you see LG logo -- quickly release these buttons and
2) immediately hold power and volume up buttons to enter into factory reset menu.
Then 3 presses of power key to confirm wipe and enter TWRP recovery. :good:
I was going mad trying to enter recovery for an hour. It appears like different models/software versions have different key combinations for entering recovery mode.
My phone was stuck at lg logo screen and i didnt have nandroid backup of the phone. so couldn't try the TOT restore method too as i waned my phone data.
Another way to get to Custom Recovery

The way that let me get into custom recovery is different.
I hold 'vol up+power+vol down' to start from turned off state and keep holding it[Don't leave just keep holding the 3 buttons]. It doesn't show factory reset screen, it get me into TWRP[Custom Rom] directly. I heard 3 buttons gets u in safe mode IDK but I got into proper working TWRP.

I have a F320S.
Hold Volume up and press the Power Button,when comes Lg Logo release the Power Button and start the TWRP
if anybody's looking for the information in this thread like i was, and the posted method doesn't work (it did not for me):
1. Power off
2. Hold volume down and power
3a. release both at logo AND press BOTH at logo right after releasing
4a. Enter recovery
You should enter recovery, but if not...
3b. Keep the buttons pressed (your phone might continue into the start animation, but if you keep the buttons press it will return)
4b. The first logo will appear. Release both and press BOTH
5. Enter recovery
hope this helps someone

this worked omg...thanks a million...
Just wanted to contribute here in case anyone else had tried everything listed in this thread and still was unable to boot into TWRP.
I'm on Sprint, stock, rooted ZVE, and I have TWRP 2.7.
1. Power off phone, wait a few seconds to make sure phone is completely off.
2. Hold power and volume down.
3. As soon as LG logo appears, KEEP holding down power... BUT release volume down and SWITCH to holding volume up.
4. After a few seconds, screen appears saying "Recovery mode" and TWRP opens up after that.

[Q] LG G2 D802 can't get into download mode

My phone is completely messed up.
i got an update form LG.

i installed manual via adb commands TWRP.
and then thing became real bad.

1 sec after i get few error codes and then black screen without ADB support.
i trierd to get into download mode after reading in forums that only this can help.
but I can't.
I powered down my phone in all possible methods:

after the phone is off i tried power it back into download mode with the next combinations:
power + V+ and then USB, power + V- and then USB,power + V+ and V- and then USB.

I will be happy to get some help.
Thanks
Ran :good:
sorry was wrong.
try turn phone off, add usb, then press volume up. I think that's it.
Hi
did no work also
I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..
Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142
This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:
Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

S7 Edge stuck on boot logo ( G935FD )

I tried flashing the bootloader from here.
Then it went crazy or something, and got stuck on the powered by android logo, however i was still able to boot into download mode the first time by holding power + volume down button
to simulate a battery pull then quickly holding the volume down + home + power again. Then I tried flashing TWRP immediately in an attempt to make it work because i have a flash drive to microUSB adapter that allows me to read flash drives from my phone ( so that I can flash the rom properly ). The last time I was in TWRP there was 0 things in my storage everything was wiped after I flashed TWRP the first time
Now im trying to go back into download mode but it just wont let me after the battery pull.
1.) After simulating the battery pull, I immediately let go when the screen is dark.
2.) I immediately attempt to go into download. It shows the powered by android for a second, then flickers then it's back to the powered by android again.
3.) I think my recovery and download is screwed. Or something is going on
=== EDIT ===
I managed to get into download mode and flash back my stock rom.
I think the phone must have read my Power & Volume Down & Home button as the battery pull because I let go of all buttons completely before doing it.
Steps to get out of bricked hell:
• Hold Power & Volume Down until the phone turns off
• Immediately without letting go of the Power & Volume Down button, press the home button as well.
• If the timing is not correct just retry.

Help! Stuck on black screen and cannot get to fastboot

I tried unrooting my 6T and something went wrong. Now when it boots it shows the bootloader unlocked warning then goes to black screen and stops. It will randomly vibrate when I press the screen or the power button. My computer doesn't recognize it and I can't even seem to be able to turn it off completely. The only thing I can get it to do is reboot by pressing and holding the power and volume up buttons.
Any advice on how I can force it into fastboot or get my computer to recognize it so I can working on it?

Keep pressing simultaneously volume up , volume down and power button all three of them until you get the fastboot screen.
It maybe takes a while...

like the first answer:
hold vol up, vol down and power butten as long as the phone boots into fastboot mode and flash fastboot Rom OR
hold vol up and vol down for about 5-6 seconds, and plug your phone to your computer. if it gets recognized (with typical sound of windows) try msm tool. And be sure you have the qualcomm driver installed.
