[Q] HELP!!!! MY LG L7 P705g can't start

Hi,
one day, I changed the permission of /system/font by accident:
e.g. I changed:
.............read....write.....execute
user.........V........V...........V
group.......V.....................V
others......V.....................V
to
............read.......write......execute
user........V..........V..............
group.......V.........................
others......V.........................
After that, I can't turn on my phone anymore T.T
When I press the power button, the LG logo appears, and then vibrate, logo disappear, after a few seconds the logo comes back and that's it!
It just stays there (I waited for 2 hours and it didn't change,so I turned it off)
Please help~
How can i fix it...

Enter download mode, and flash your firmware like this: http://forum.xda-developers.com/showthread.php?t=2409308 or just open LG Mobile Support Tool and select "Recover Phone". It does the same thing but it's easier.
Nothing's lost, you'll get it fixed.

hi, thanks a lot.
but what is "version"? There are version 10C/10E/20A in http://lg-phone-firmware.com/index.php?mod=Lg+Optimus+L7&paese=RGS/ROGERS&id_mod=13 ...
How can I know which one is the right one?

My guess is 20A is ICS, 10C is the first release of Gingerbread, and 10E whatever update they did to it. If you're not sure, go with the LG Mob Supp Tool, it's safer and easier.

Did it work before with the exact firmware update you had? Remove the battery of your phone and re-insert it (don’t turn it on). Press and hold Volume Up button and Volume Down button. While you are pressing the two buttons, press the Power button or insert USB cable (try both if it doesn't work). Or try with: phone off, volume down + insert cable. I don't know the exact combination for your phone.

try vol down+power
when keys light up, touch menu key (vibrates)

Even if you can't go to download mode you'll still be able to use kdz on it. just plug it in and start it. And btw, be careful next time. My Optimus L7 got hard bricked and I needed to go to LG for them to fix it.

Hopeless....

there are 6 days from now...l have no recovery,download or fastboot mode...only this fu**ing LG logo...l can use adb commands on windows 8.1 but it not help very much because my device is not rooted and and can't run adb shell( device read-only error)...all l have to do is to root the phone, BUT HOW..I've tried manualy install root to get adb shell work...no chance...l have another laptop with ubuntu,but this time my device is attached offline on ubuntu terminal...HELP!I dont know what to do:crying:
edit:LG G2 F320L
is there some way to get fastboot mode working if i'm not rooted?...
edit2: 3 weeks and l found nothing for my phone:crying
edit3: 4 weeks and no chance to get my phone back ...

Which phone? Asking for help with zero info on what you're using and what you've done isn't likely to illicit much.
Just do a full reset (from power on) and then flash stock kdz.

l send my phone to LG service 2 day ago and they contact me today....bad news: my phone can not boot to the end and can't be recognized by any device(original LG tools and cables etc.) to be repaired.l have to send it back...... where the phone was purchased(Singapore)

I feel bad for you but hope you've learn a lesson, read more and more and more before doing anything to your phone. If you don't know or not sure or unclear, don't go for it yet.
Anyway, still under warranty?

To switch off your phone. Hold the power button about 10 second. you will see screen completely black, or unplug your battery.
To do hardware reset for F320L. Press and hold power+ volume-, when LG logo appear release power button only and press power again. You can see Hard reset mode.
After that, if your phone still not reboot. Try to flash KDZ or TOT in download mode.
To access download mode : Press volume- and plug your phone to PC
If you can not access download mode. plug your phone to computer and check what driver you have in device manager. If you got only Qusb-Bulk. Its bricked completely.
If you plug your phone to Windows and got a lot of message come up to format it. press cancel and don't format it. then follow :http://forum.xda-developers.com/showthread.php?t=2582142

when l'm using VRoot app ad ex....this app recognized my device lg g2 f320L , but the software is from F320s..so this avoid warranty...solution is to change the motherboard...but it is 250 fuc''g euros

Can you use adb to push file into /system folder ?
This is the only way to replace your build.prop file to change F320s to F320L

Well I am a bit confused... mostly because this isn't so clear...
When you hold power button it reboots, but if you continue to hold it, it will shut itself down.
It's this way on LG G2 D802 and should be the same on yours.
When it's shut down, hold volume down and then power, when you see the LG Logo release the buttons and hold again volume down and power button. This should get you to recovery...
Try it like this?
I play around with my G2 alot and I have had the LG logo issue several times.
I use PhilZ Touch Recovery and TWRP to backup valuable files.
PhilZ Recovery with AROMA File Manager and if that isn't set up I use TWRP Recovery.
You need a USB OTG connector for this...

Try this for getting to download mode it worked for me:
1.) don't push any buttons, just plug phone into computer using usb cable
2.) push and hold power button + volume up button
3.) do not let go when you see LG logo, continue holding
4.) after a few seconds you should be in download mode

I have the same problem, no download mode on my G2 (European version, stock kitkat without root, bought it a week ago).
Just to be safe, the way I tried to launch it into download mode was:
1. Powering off the device.
2. Holding the volume up button.
3. Plugging in the USB cable (while still holding the volume up button)
The LG logo shows up for a while, after which the charging animation shows ups...

Your phone must be turned off
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
that is the known method for G2 unless you flashed a custom boot-loader or changed the keys to enter download mode or recovery etc .... now try to enter a hard reset mode but don't apply it or all your data will be gone i say again don't approve it it is power+Vol down
if it works i think the keys combination are still in default then try to enter download mode again
if it didn't work return the mobile to be fixed or changed

Thanks for your reply!
The method you described is the same as the one I used, unfortunately it doesn't seem to work. I can't seem to get it to boot into recovery either...
I believe this reddit post describes my problem:
https://www.reddit.com/r/lgg2/comments/2n4gqa/unrooted_lg_g2_on_stock_android_442_kitkat_will/
The OP's conclusion is:
So I rooted and installed AutoRec and that got me Download Mode. Afterwards I used LG Flash Tool to flash the stock KDZ file onto my device to unroot it and to see if Download Mode is still enabled which it was not.
I believe this is LG's way of preventing users from upgrading to unofficial/unreleased firmware.

I managed to fix the issue by performing an emergency recovery using LG software. It must have been caused by one of the OTA updates.

LG G2 Boot security error after trying to flash SuperSu after going to LineageOS 14.1

I've been using Cyanogenmod 13.1 (rooted) and I decided to flash a ROM with Nougat. I flashed lineage-14.1-20170320-nightly-d802-signed and open_gapps-arm-7.1-mini-20170325 and everything worked fine except I didn't have SuperSU. I tried flashing SuperSU-v2.79-201612051815 and when I tried to boot into system I got this screen (with the LG logo below) http://i.imgur.com/O7vOtab.png I tried many methods like this https://forum.xda-developers.com/showthread.php?t=2582142 and this https://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 to no avail. In Linux when I used the ls /dev/sd* command in the terminal the phone wouldn't show up and later in Windows I got the PC to recognize the phone as Marshall USB Composite Device 9006 http://i.imgur.com/a5WHV9P.png and in Disk Management the phone partition shows up un-initialised http://i.imgur.com/XaVKIu7.png . Help I don't know what to do now. Tell me if I should provide more information.

I had the exact same problem. Then i found a solution. Just dont flash the normal Supersu, you need to flash the Supersu BUMPED file. Just go in recovery, press 10 sec the power button to be sure the phone is off, then hold volume down and power button until the logo appears, then release and press again (fast) then choose yes, yes. Just flash the Bumped and if recovery asks to do root choose NO.

Yeah Bad same Problem, turned off and it went on, then again bootloop. But if you press the power button long enough then its completely off. In cyanogen mod i had Problem that i couldnt get into recovery with power button+volume down.
So you should flash kdz, get oneclickroot for LG g2, then autorec lollipop to get recovery. Then flash Rom + gapps + The bumped file.
If you dont know how to flash kdz, you can ask here. I will help
Good luck

Yeah Ok. When I wanted to turn It off, I just pressed the power button until the screen went black and the logo came again but after 2-3 sec the screen went black again, then it was off (just hold power button for 10sec)
Try that when your phone keeps restarting

Get the lg mobile support tool, install it. Then open and connect your phone via download mode, it will find the phone and download the kdz for it. That should work.
If it doesn't install automatically, click on additional options then click on set upgrade error back, or something like that.
Before all that install the driver from

Then you can start with lg mobile support tool

Stuck on bootloop after 9.0 from LGUP

Hello there!
I've tried to go from android 9.0 beta build to the released LG one for my country (H87030a_00_PLS_PL_OP_0905). The installation went ok. But the phone was stuck on logo. So I did factory reset by holding vol- + power button. Now the phone is stuck on boot logo, and it doesn't turn off.
After that I've tried going with this instruction: (https://forum.xda-developers.com/lg-g6/how-to/lg-g6-unbrick-method-t3935924). But on clicking download button step in QFIL, there goes "Download Fail Switch to EDL FailFailed to Switch to Emergency Download Mode"
Sooooo I would try to install again the original kdz file by LGUP again but the phone is stuck on LG G6 ThinQ logo :|
Would anyone help me out with this?

Worked, I am in download mode, but when I try to go through link instruction to install working KDZ, after clicking "start" the error window pops up:
"Error: 0x81000302, Please use latest DLL
LAF Protocol version is not match DLL=116608592
Device = 124133408"
EDIT: Tried with not "partition dl" option but with the upgreade one. Everything went fine but! Now I am back at the solution of the problem. Back at LG G6 ThinQ powered by android logo :/
EDIT2: Menaged to make it work. It turns out that despite that I bought my phone in local store in Poland, it doesn't mean I get phone specificlly sold for this region market. I got it for POC region. It makes difference :| Thanks anyway guys

Have you already solved your problem? I have exactly the same as yours, stands on the LG logo and you can not turn off the phone or enter the download mode
