Hello people of the world.
My LG F240L has got its power button damaged(HArdware problem most likely). So now i cant boot into the device. I dont want to flash the whole rom again cuz i dont want to lose my data. Is there anyway i can use LG Flash Tools or some other software to reboot my off phone???? i just need it turn on just one more time and then i can make other arrangements. All help will be appreciated!

You can Using reboot app on chplay or search google

If your phone is completely shut down, the simple way is to:
1 - Plug the usb cable into your phone, as you normally do for charge it or connect it to pc.
2 - Wait for the Lg logo to appear.
3- Then quickly unplug the cable and wait for the phone to reboot normally(don't wait too much or the phone will enter in "charge mode"). You should see how the Lg logo blinks, then your phone will wake up.
It worked on my e980.

Pressing once does not turn it on. You need to hold it down for few seconds, til it vibrates. Then you can release it.
I do this but wont power on. I dont know why.
Its recognized on my computer as qualcomm usb or zeus flash device.

It's soft bricked, you need to recover your phone with Sony Update Service.

You won't need to power on your phone for this. Install Sony Update Service on your computer and follow the instructions given.

Now connect cable.
Should work now and update service will do its stuff.
Thank you guys but
It work, green led and updates loading, phone detected as s1boot download.
I unplug the phone and hold power button until vibrate but nothing
Now when I plug phone on the pc, the computer detect qhsusb_dload device
what is the problem ?
That is strange. I am running out of ideas to help.
Last idea is to use Flashtool and flash a stock GB/ICS rom.
Use this thread for all instructions and download links - http://forum.xda-developers.com/showthread.php?t=1642480
I forgot if flashing by flashtool requires to have unlocked bootloader.
Ok thank You
I will unlock the bootloader and then flash the phone

[Q] HELP! Lost download mode! LG E970

Hello, So i tryed to flash to CM10 rom for LG E970 and my screen went black after reboot. So then I tried t go back to stock with LGNPST and it would get to the logo and stop. So then (lol) I tried using a teenybin instead and now I can't get download mode to show up and all the screen will do it show a gray battery with a lighting bolt and sometimes when trying to power on or get to download mode it'll act like it's about to do something and shows a black screen with google in grey and an unlocked lock at the bottom of the screen. Help is all lost or can i fix this??

Use the KDZ Updater with the latest firmware version of your phone...
First, download and install the latest lg driver. (your phone must be unplugged when installing)
Second, download the LG E970 kdz.
Third, "google" and install the kdz updater.
Fourth, put your phone in "Download mode" by pressing both volume keys and plug into usb port (wait 2-3 seconds, your computer will load the driver)
Fifth, open the kdz updater and select "3GQCT" in type...and "CS_Emergency" in phone mode. Then browse & select the kdz you've just downloaded...and press the Launch button. It should take about 8-10 minutes to complete...your phone will reboot around param.94 then you can unplugged it and let it boot normally.
Finally, make a "factory reset" to erase all previous data and plug your phone to wall charger to gave him some fresh blood.
Give us some feedback & good luck :good:

Try to get in donwload mode pushing together volume+ and volume- and then plug in the usb cable (to your pc) do not release the buttons until you see the download mode logo on the screen. The phone has to be off before doing the procedure if it wont turn off , push the power button for something like 15 sec, should go off that way
Good luck and in the event that you can't go in download mode anymore , take it to assistance. It's the only way.

Warning to everyone please avoid using Freegee Relock feature it can cause semi hardbrick or worst a full hardbrick.
I just had a SEMI NIGHTMARE using Freegee
I installed Freegee, then installed CWM classic installation, everything went fine also made nandroid and efs backup. So I decided to Relock and then "semi hardbrick" happen.
Why Semi Hardbrick because you think you can no longer use the usual Download Mode tricks. (Insert USB, when battery show press the combo key) but that will not happen no matter what you do.
What you see in the screen is a freeze up LG logo with error like secure boot encryption in two lines or something like that.
The hard reset command still work but you cant go any further you will see the error again.
Ok here's the trick and its very tricky its like catching a fly for a Download Mode.
Normally during boot LG logo normally flick twice, then the battery shows if your insert the cable or the animation Logo if loading the system, mine don,t during this trouble time.
What happen that it seems you cant turn off your phone it persist to turn ON with boot encrption error on the screen but to turn OFF you press and hold volume down or up or both and power (this is the key to go Download Mode)
I used the volume down + up and power button
While turning off the device and you think the logo stops showing up release the key then quickly insert usb cable when the LED light turns ON quickly press the Volume UP, DOWN, POWER congrats Download Mode ^_^
I reminder to anyone Please don't use the Freegee Relock function. But if want to witness the near death experience go ahead its safe now ^_^

so please confirm you were plugin in the whole time right??

yawako said:
Yeah I remember I was still plugin (charging using PC) when I use the Relock function of course I have to reboot after that.
If you mean when it gets error you cant plugin your usb because it will trigger the device to turn ON and it persist to turn ON

when you are plugged in either by charger or computer, you might not enter recovery or download mode.
turn off your phone by pressing power for extended time.

You think I dont know what I posted here why not try it for yourself if you have a unit like mine.
If only I took picture of that damned boot error.
Are you sure about download mode? Not using cable?
Click to expand...
Click to collapse
what i have seen here and done myself, sometimes no matter how smart you are or knowledge you have, one always misses the smallest of the things.
yes if you are plugged in you will have a had time to get into download mode or even recovery. sometimes it just wont enter either.
also sometimes phones seems turned off but its not that's where pressing power for extended times comes up. otherwise it will try to boot on plug.
You are far from hard bricked (that's the good news). If the device turns on at all its not hard bricked. If you are getting a security error its most likely because you uninstalled some system apps and didn't put them back before relocking. You might also have not had a backup of your boot.img. Freegee will restore your phone without a boot.img backup if it can't find it, since at least that would put you close enough to stock if you had to take it in, and you can still use download mode.
You can get to download mode because you see the lge logo, download mode is before that logo in the boot sequence.

[Q] Lg g3 vs985 not going into recovery while device is powered off

Please help lg g 3 won't enter custom recovery I've tried all button variations
Please someone help I have a rooted g3 and don't wanna brick it?????

Please someone help
I've seen people are viewing this post if anyone know how to fix my problem please help or message me, the minimal adb won't work unless the device is turned on in usb. debugging, I can access my recovery with phone on easily but while it's powered off I should be able to get to custom recovery by pressing volume down and power while phone is off, but this method isn't working. So if I get in bootloop I can't get into custom recovery...please anyone any ideas
Well it should be as simple as holding down power and volume button down things but i guess you've already tried that method many times and it didnt work so you ask then, right?
If your phone in bootloop, you can flash tot files and it will back to stock re-root and re-install trwp.
If your phone still (or already) normal, you can download an app that can take you to custom recovery such as rebooter or power menu, thats it.
Yea phone isn't in bootloop, but if I put a Rom on phone I have no way to access the recovery because the volume and power won't take me to the recovery, so if it goes into bootloop I'm outta of luck I don't understand why the hardware buttons won't take me to the recovery, have you ever heard of this problem

How long are you holding the vol down and power buttons? It should be around 15-20 seconds, then your system recovery screen comes up, you choose factory data reset, yes, and then TWRP comes up. If that isn't working - are you sure your buttons are working OK?
If the phone is turned off is there any other way to access it while phone is off?
Yes buttons work fine I hold it down and it just goes to Verizon screen ?
Actually when I hold it down it just stays on logo and reboots back to logo over and over and over
Actually I hold it down and it reboots to logo over and over its like there's no recovery there I don't understand lol
If anyone has any ideas or thoughts on how to fix this please let me know

OK... Does your phone boot into your ROM at all or are you bootlooped? If your phone boots, download an app called flashify and get the proper twrp .img file for your model and flash the image using flashify. It's an easy app to use - just make sure you're using the correct twrp .img for your phone...from here: http://forum.xda-developers.com/lg-g3/orig-development/recovery-twrp-touch-recovery-2-8-2-0-t2966129
If you are bootlooped I would suggest starting over and reflashing back to stock using the tot or kdz method. Here is a guide: http://forum.xda-developers.com/verizon-lg-g3/general/restore-verizon-to-stock-t2827878 I know it can be a pain to get the download tool working properly sometimes, so it may take some effort to get it working, but be patient (and read a lot if you get stuck) and you will get it working.
I don't know how you got borked...maybe it was an un-bumped twrp image? Either way, it is what it is, just try not to do it again Good luck.
Thanks much I'll try this
When this happened to me i would
1: remove battery
2: insert battery
3: hold volume down and lock button at the same time
4: When the LG Logo pops up release the lock button for 1 second (while still holding the volume down button), then press down again
5: A data reset/restore menu appears, and when you choose to reset/restore, TWRP boots to recovery.

How to reboot Xperia S

Hey, i have installed TWRP recovery. It works, i can get to it and make backup etc. But how I can power on my phone? Really, I have no idea. Normally I should just push Power On button, and it will work. Now it doesn't. Phone is restarting all the time to sony logos, then pink led, then blue and power off. Then after few second phone is restarting again and again. How I can just normally power on my phone?

Please tell all the things you did before the problem begins. What have you did last thing to your device? Put your device on charger until your led turns green.Then flash official firmware by flash tool.
Another thing do you able to boot to twrp recovery?
So i have unlocked bootloader (but like 2 months ago) and installed twrp recovery. Actually now, since the battery decharged, because it was restarting all the time, i can do ****. I can't put it on charger, because its restarting after like 5-10 minutes after charging. I can't flash my phone, because its decharged or its stucked on sony logo. I can't use the official repair tool, because its not recognizing my phone. Now I can't even get to the recovery.

ok calm down.Its not a big problem.Just follow these steps.
1. while you see sony logo or when the phone is turning on ( Press and hold VOLUME UP key+POWER key simultaneously).While you feel a short vibrate release the keys. Now put on charger.hope you will not get the automatic turning on problem.
2. Then Download Flashtool software from internet. ( official repair tool will not work coz you have unlocked your boot loader)
3. Download your mobiles official stock firmwire.Then flash it using flash tool.
You can learn about flashing ftf(firmware files) by flashtool from internet.
Best of luck
Ill try to do that 1 step, but I think it wont work. And I have already googled those next steps. Anyway thanks for those steps
Yep, nothing actually works. I get the sony logo, start pressing power button and volume up, then green led is lighting. Its fine for like 5-10 seconds, then its decharged, need to charge for like 20 seconds, and then again sony logos appear. Infinite loop.

The green light means you are on flash mode.the mode is used to flash firmwires.so you need to install flashtool.then install flash mode drivers.then do the steps to flash firmware.
But I can't install anything, since the xperia just restarts after few seconds or just power off, because I can't charge the battery.

You have to install flashtool and drivers on your PC.search on google guide to use flashtool
I have installed drivers and flashtool, but man. You don't understand me. The phone is not charging when im in flash mode. And I can't charge it, because the screen with sony logo can't be powered off. I can only go to flash mode, but in this mode, phone is not being charged. And if I try to flash firmware the phone just run out of battery.

1. R u able to power off your device by volume and power key?
2.OK you can flash stock kernel by fastboot mode.it can be done with a low battery.(may be you have a corrupt kernel)so after flashing kernel you can try to turn off your device by pressing and holding vol up +power key.don't let go any of these two buttons until you get a vibrate.I have never listen or faced this type of issue where we can turn off our device.

Best way is to go to a mobile shop and ask him to remove the battery by unscrewing. You can try at home to do that if u have tools to unscrew

Do You still have a working recovery? If yes, then You can push a ROM zip to phone via adb while being in TWRP and then flash it. Also, again if You have working TWRP, You can turn off phone via it by going in TWRP>Reboot>Power Off.
You can also turn off Your phone by pressing Power and Volume Up button together. You will first get a single vibration. Keep the combination pressed, then You will get three vibrations. Now Your phone will be turned off fully. This combination will work.
Whenever You connect Your phone to PC/Charger, Your phone will charge, regardless it's in bootloop or not.
But, can you read? I said i cant get to fastboot, cant power off phone, cant acces twrp.

You are asking for help and mirhawk is trying to help you.you should not write him like that.if he didn't read your previous post then you can tell that politely. If you behave like this then no body will help you.XDA teaches us to be friendly with all first.
xDD He should spend 2 min of his life to read the topic instead of writing useless posts. Anyway, phone is dead, there is nothing you can do actually or its not even worth. Close topic.
