Try the Unbrick methond in this link I'm pretty sure you can recover your phone this way .I have done chaotic things to mind and always manage to get out of anything by doing the Unbrick method.If you do decide to do it the trick is to uninstall any of the drivers you currently have installed for the phone and install the once that come with the Download file for the unbrick method.O and connect your usb to the back USB slots if using a desktop.

Yeah, you can't flash CWM with the bootloader from official ICS. You have to go through the unbricking guide.

Make sure you do your own backup
e.g. rooted access and backup your existing recovery image to /sdcard
adb shell

How to get recovery mode:
Power off your phone, then press "Power + Vol Up + Home" at the same time
or
if you have USB connected (debug option turn on in your phone), issue "adb reboot recovery"
PS: TWRP sometimes has touch problem (still don't know why), you need to use power off method to get recovery mode (it works almost).
How to restore your stock recovery
(I am assumming your backup recovery (stock) image in /sdcard)
adb shell

Touch is weird. I think there was a problem with screen resolution
and I cannot flash F240S's TWRP.
F240k's works just fine, though

for flashing permanent recovery has both good and bad side:
pro: we can restore any issue by twrp or cwm backup
con: we cannot OTA update directly until we flash back stock recovery

1) to recovery: When your phone in power off mode, press "Power + Vol Up + Home" at the same time, wait it flash to boot twice
2) do you have rooted your G Pro?

make sure you have adb drivers installed correctly
check driver, reboot PC + mobile and re-try
PS: test
adb devices
you should see your device ID, otherwise your adb drivers in pc is not working

no... it sounds L is different.......
my founding, when comparing K & S are identical binary
but L is totally different from K or S (either TWRP or CWM)
it sounds strange...to me, if the LOKI using the the same signature for all KR version
If you can use CWM on K or S, I think it is ok
can you test for me, try flash gk-twrp-f204S , and see whehter you can use it?

[Q] Fastboot UDC?

Hello, I tried to flash twrp recovery on my brothers Sprint LG G2. He has the spark update. Everything seemed fine but when I try to get into recovery mode it says Fastboot started and UDC after it. Now my question is how do I make sure he has a recovery, he wants to get hotspot MOD. Do I use Freegee to downgrade his aboot then flash the lokied twrp file? Or do I need to go back to stock to avoid bricking ?? Please advise!
Thank you !!

Use autorec to get recover (its in lg g2 general forums) and if that dont work you will have to .tot back to stock and use ioroot 25 to root and autorec for recovery

[Q] Is it safe to install p930 custom recovery on p935?

So, i rooted my Telus Lg Optimus lte (P935) with Cydiaimpactor. Now im trying to install Rom Manager and i am not sure if i can use P930 recovery on my P935. If not i want to know what recoveries work on this phone.

Hi,It is safe because p930,p935 & p936 have same hardware.
Download the recovery.img and put it in the root of your sd card, then run adb . After that, run this following command:
edit:enable usb debugging else it is not working
adb shell
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
or you could just install the recovery through rom manager by clockworkmod . . .
Flash at your own risk

Thank you !!

LG G4 stuck at LG LOGO screen cannot flash back stock img

HI,I am having LG F500L,running Android 5.1,build number LMY47D,sofware version F500L09a. At first, I backup my system img to the phone memory. I typed these commands
Send_Command.exe \\.\COM3
then type id
dd if=/dev/block/mmcblk0 bs=8192 skip=65536 count=548352 of=/data/media/0/system.img.
After done, I opened my phone storage then there is a file named system.img.
Then I downloaded rooted img F500L10w online provided by a forumer. I renamed it to system2.img and copy it to phone storage. Then I open cmd typed these commands
Send_Command.exe \\.\COM3
then type id
dd if=/data/media/0/system.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0
After done, my phone reboot and stuck at LG Logo screen.
OK,then i want to flash back my stock system.img. I type these commands again.
Send_Command.exe \\.\COM3
then type id
usually it will show uid=0(root) gid=0(root) context=u:r:recovery:s0 , but there straight show # after 1 seconds.
Then i type dd if=/data/media/0/system.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0
after 1 second it show #
Now my phone stuck at LG Logo screen. I cannot flash back to stock img. Can i know how to solve this?Thanks.

Search the general thread.. your answer is somewhere there, someone made a thread on how to go back...also if it comes back immediately then do it again and again it will eventually work.

Same situation, using F500L 09a, ROOTED, and flash the 10w -> get stucked on LG logo

I created the backup system.img for granted before this, so I have.
But you said it still did not work. that's it?
After the flash 815, you could use adb and the "send command" to flash your system.img?

I tried use adb and the "send command" to flash my backup system.img. My phone still stuck at LG Logo. Because the system partition already changed to H815 and does not same with F500L so it cannot works.

Im in the same exact situation.
It looks like we can use h815 10b kdz but loose signal strength. But it boots.
We need to figure out how to backup f500l original partitions, as much as we can before so we can restore it all afterwards.
Need to figure out how to calculate bs, skip, count ect.. Of each partition. Not sure exact what we absolutely need. Assuming system, boot, modems at minimum.

What I dont understand is why your phone doesnt work. Because according to what you posted here is what you really did. You flashed your own backup system.img and not the rooted system2.img. So your phone should have stayed as it was.
Unless youve mistyped..

F500L does not have kdz or tot to go back to stock. So that doesn't work for us.

OR we need someone with a working F500L to back up his or her system, boot and modem partitions and share with us

Thats awesome. For 9a or 10a? Did you get boot.img as well?
If you could link it in the thread it would be great and might help others that need it as well.
Have you been able to get yours to work again?
Should be 3 modem partitions, how did you get them? Id like to back mine up too.
