Hey,
They are two ways to fix this, first flash the modem in TWRP (Never tried this my self so not so sure it works or not) described the same problem in this thread study it if it help you [Guide]Restore to Stock "Bricked" "Unlocked" LG Optimus G f180,E97x
Second as I told you earlier go back to total stock try the KDZ updater for that if it gives error then flashing the tot file through LGNPST, you will be able to flash any desire stock KDZ after that via R&D Tool or use the first method to unlock the bootloader in above thread and then flash any custom rom you desire.
If you do go to original stock of your rom remember to backup the modem and EFS partition (if not already did, they contain your IMEI incase anything else go wrong) and copy them to safe place in computer or cloud.

[RECOVERY][UNOFFICIAL] CWM RECOVERY v5.0.2.8 for LG Optimus 3D Max P725 and P720H

Hello Guyzzz!!!!!
A Great Newzz for ALL!!!!! First the recovery was not compiled by me!
But NOW I am BACK with a FULLY WORKING RECOVERY AND FULLY COMPILED BY ME :good:
We have now a FULLY WORKING CLOCKWORKMOD RECOVERY v5.0.2.8.
The CLOCKWORKMOD RECOVERY is TESTED on :-
1. LG OPTIMUS 3D MAX P725
2. LG OPTIMUS 3D MAX P720H
I HELD NO RESPONSIBILITIES FOR BRICKED PHONES. YOU MAY TRY ON P720 BUT AT YOUR OWN RISK.
Credit Goes to :-
1. I, Me and Myself ( For taking the initiative,compiling testing and removing all bugs )
2.. Cynogenmod for the SOURCES.
3. P720H tester ZOOM.
According to me, the CWM RECOVERY is fully working.
HERE ARE THE STEPS TO INSTALL THE CWM RECOVERY :-
Download the CWM RECOVeRY FINAL.zip from the link given below :
http://www.mediafire.com/?p59d9ppjlhkcp67
Copy the cwm5.0.2.8.img on the ROOT OF THE SDCARD not the External SDCARD ( Root of SDCARD means not in any folder )
The BIGGEST REQUIREMENT IS YOUR OPTIMUS 3D MAX should be ROOTED!!!
Now download ANY TERMINAL EMULATOR from the GOOGLE PLAY!!!!!
You can try this :-
https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en
And install it.
Type the following commands in TERMINAL EMULATOR :-
su
dd if=/dev/block/mmcblk0p6 of=/sdcard/mmcblk0p6.backup bs=4096
dd if=/sdcard/cwm5.0.2.8.img of=/dev/block/mmcblk0p6 bs=4096
Once complete.
Turn off your phone.
1st hold 3d key then volume down button and at last power button.
Keep holding till the LG LOGO appears and leave when it appears.
You will enter the CWM Recovery
Proof of the Recovery :-
Worked like a charm! First I couldn't get the # to appear (the phone WAS rooted) so I just used the terminal emulator you specified, and that solved it.

is it somehow possible to activate nable adb access in CWM 5.0.2.8?
or can i flash a zip to do this?
Again .. i can enter S/W Upgrade Mode
There i only see S/W Upgrade
Please wait
while upgrading....
(NO ADB ACCESS! But the Tool recognize the phone but won't let me start the sw upgrade.)
In CWM i can mount & unmount storage and flash zip files or backup / Restore.
BUT no ADB access and Restoring the backup i made doesnt work either)
What breaking my head is that the LG Update must had set a flag to boot into recovery after i downloaded it so mindless.
Since then i stuck in cwm bootloop. There mus be a way to reset this flag. Somehow!!!)
Its over .. i flashed CWM-Loop-DeLooper -> now i stuck @ LG Logo.. also vol+ to enter S/W Upgrade not working anymore. Now its bricked! ARGH!

Thanks a lot! Its strange that in any instruction not says this way of use CWM, i read a lot differents cwm instructions, but the always the same - use power off key ot use 3d button.
Who don`t how to use CWM menu :
"properties button" - up
"home button" - down
"back button" - back
"search button" - ENTER
Cannot select options in cwm
Hi Eklovya,
Brilliant job done!!
I have successfully rooted and installed CWM following your method.
However, when i go boot to CWM, I can use the volume buttons to highlight the options (I wanted to backup), but I am not able to select the options. i tried the power button and the 3D button, no go. What do i do?
I just exchanged my P920 and got myself this P725 today!!!
schubeir
EDIT: my bad!!! found the solution in the post just above!!!!
schubeir
(possibly long post , I will try to make a post at least a little fun to read).
Guys, I humbly come before you, kneeling and desperate, trying to solve my problem .
I've serarched XDA and a lot (!!) of others forums and comunities to revive my P720H (LG optimus 3D Max in Brazil).
I am not a complete noob in custom firmwares for Android, but this time, the LG phone gave me a hell of a headache (and almost a divorce, for the 3 days going too late to bed, trying to solve it).
I will explain what happened and what I've already tried to do and the results.
Causes:
I've tried to install ClockworkMod in my P720H because it still was in Android 2.3.6 (I think).
I've successfully rooted the phone using this thread: http://forum.xda-developers.com/showthread.php?t=1886057 with the SuperSU app on GooglePlay.
When I asked CWM app to reboot in recovery mode (to wipe things and install the .zip file on the sdcard root) things got bad.
My phone could not get passed the LG logo anymore.
So far we have a cause: CWM app did something to the phone. I am not able to boot the recovery menu nor to pass the LG logo on the screen.
Over the communities we may find that it's a common issue.
It is important to say that I am able to enter the 'S/W updating' state. When I connect the phone to the computer, holding VOL+ and placing the battery, I got the S/W screen.
What can I do? In several posts (even here in xda) we may find 3 or 4 different solutions to restore the phone. I think I've already tried everything, but I am sure that the steps became fuzzy in my read and I mixed the solutions in the end.
Drivers:
- I have already the drivers installed: When I connect the phone (with or without battery and with or without vol+ pressed) my Device Manager recognizes everything. I don't have any component marked as 'unknown device' or with exclamations points or anything. This is a good thing, I guess. I had to install more than one thing to solve every driver problem. I don't remember exactly, but I think that the LGDriver-something and the omap4430 something too.
Solutions:
- I have tried the LG Support Tool and so far it appears to be the closest to a solution that I've reached. With the phone connected (in S/W mode or no), I insert the IMEI and the software recognizes the model and starts downloading something (500mb approx.). But after decompressing, during the installation phase, it gets stuck at 4%. I waited for more than 20min and still got nothing better than 4%. It appears to be a common issue too.
- The LG_FlashTool (version 1.2) does not work either. In fact, it does not even recognizes the phone. I've changed the COMport to 41 (according to some guide) on Windows Device Manager and chose the port 1 on LGFlashTool. Even after selecting the kdz, bin and fls files, the software does not connect to the phone. I don't have a screenshot here, but I've seen here in xda that the software displays the model of the phone on the top and a READY message on port 1. Mine does not do it.
- KKDZ_FW_UPD_EN: I've tried this one but it does not even start working. The interface is not that good, so I don't know where I may be failing. I need to 'read phone information' or not? What do I have to chose on each combobox? How to proceed?
And why the hell is there so much .exe on this thing? Do I have to run a apache server to do something?!
- OMAP4BOOT: This one connects to the phone and works, I think. But I don't know its purpose. It's just to place the phone on 'S/W updating' mode? If so, it's useless, because I can enter it easily. If no, maybe I am missing something. Either way, I don't have a version for the P720H. If I remeber correctly, it proposes P999, P760, P870, ... I choose P760 to test it and it works (apparently, again).
- SmartFlashTool: I don't remember if I have already tried this one. As I said, it was too much already.
- NVFlash: I've found it only to G2X, so I didn't know if I should try forcing it to my model. I can give it a try if you help me.
Other softwares and downloads:
KDZ:
- V10B_00 and V1A_00: found today and downloaded for my model and country (will try to extract things and use it later).
- LG_P725_V10F_00: I was using this one until yesterday, because I didn't have the one to P720H
- LGP700AT-01-V10d-232-03-SEP-11-2012+0.dz : Found in an indian repository of some kind of LG data leak. Apparently is useless. DZextract gave me nothing.
DLL: LGP720_20120330_LGFLASHv1377: Needed in some of the softwares above (LG FLashTool? I don't remeber).
BIN and FLS: LGP725_LG_P725_V10F_00_AP.bin and LGP725_LG_P725_V10F_00_CP.fls, extracted from LG_P725_V10F_00.kdz. I don't know, but I should try extracting these from the V10A_00, because apparently is the correct one for my model/country (I am not in my house right now).
Well... :crying:
tl;dr version:
I am facing a LG logo boot loop in P720H. I've tried to reboot CWM in recovery mode but it didn't work. I've tried several approaches but I don't even know what is the point of each one. I found that this is the best topic to use, because is one of the fews that covers the P720H.
I have all those softwares and almost 5gb of downloaded material (kdz, img, bin, exe, ...) but I don't know what I am supposed to use.
In the end, I want my P720H in android 4.x if possible. If not, I just want the crap 2.3.6 again. :crying:
Can you help me? I am not a total noob in custom firmwares and roms, and I am willing to pass all the information that I can :fingers-crossed:

Can i use CWM and EXrecovery (v19c) for v20c rom?
Hi @alamatnitotoy !
Me and my friend, who has su880, were testing the v20c kdz.
We flashed v20c kdz using KDZ updater, smartflash and even we tried the offical LG update upgrading from v19c to v20c.
After every way of flasing v20c the phone always stucked at LG boot logo. So We read back every partition from the phone and it turned out that the LNX partition, which contains the kernel, is empty. I mean the kernel was missing after every flash of v20c, but every other partition was okay.
We extracted the the every file from the kdz and the the kernel image was empty in this case as well.
I don't know what is it. Maybe we are doing something wrong or LG simply left out the kernel file from v20c?
Did you flashed v20c?

yes i did flash the v20c. I had that problem before also when using other flasher other than the kdz updater. also sometimes when its failing, what i do is i run the file "Root v20c" thru apx before using the KDZ updater to upload the v20c

Thnak you! The rooting-forv20c.rar contains the v20c kernel file.
I need CWM for v20c.Do you have it?
@alamatnitotoy I looked deeply into why flashing v20c brick your phone. My statement that the kernel image is missing from v20c was wrong. The kernel is there but an wrong place. When you use the extractor from P990 AIO toolkit to extract the image files from AP.bin file, the extractor shows you that which image file is at what OFFSET (or address) in the AP.bin file. Here is what am I talking about:
Code:
[01] address=0x00100000 size=0x00400000 // bct file
[02] address=0x00500000 size=0x00200000 // partition layout
[03] address=0x00700000 size=0x00200000 // bootloader
[04] address=0x00900000 size=0x00600000 // recovery
[05] address=0x00f00000 size=0x2bc00000 // system
[06] address=0x2cb00000 size=0x00600000 // kernel
[07] address=0x2d100000 size=0x12c00000 // internal sd content
These adresses also used during smartflashing. These adresses tells the smartflash where is the kernel image and system image and etc in the v20c AP.bin file
If you flash v20c and you read back the 12th partiton with nvflash you can see only zeros.
If you open teh v20c AP.bin file in a hex editor and you go to the 2CB00000 offset you can see there is nothing just bunch of zeros, the kernel is not there. The kernel actually at 2E000000 offset. Not just the kernel is at a wrong offset, also the sd-img is at the wrong offset. sd-img should be at 2D100000 offset, but in the v20c AP.bin it is at 2E600000 offset. So, when you flash v20c the kernel partition will be filled with 00 hex values and the internal sdcard got damaged as well, because the kernel image gets flashed to the internal sdcard. This cause the Stuck at LG boot logo effect, even if you flash v20c kernel to the righ partition with nvflash, because the internal sdcard is damaged.
Fixing v20c AP.bin file:
There are only 00 hex values From 2CB00000 to 2E000000.
Delete those 00 hex values, then the kernel image and the sd-int.img get to the right offset
Insert the same amount of 00 hex values as the amount of deleted 00 hex values to the end of the v20c AP.bin file to keep the size of the sd-int.img, then save the modifications.
I flashed this modified v20c AP.bin to my p990. I read back every necessary partition with nvflash and everything was okay. bootloader, bct, partitions, kernel, recovery, system are aon the right partition so maybe it's fixed, but I am not 100% sure just 98% because I don't have su880
I want to share you and with others the fixed v20c, so you can test. You can download it here
I want to share my google drive folder as well where you can find my works with su880. It has cwm for v19c and v20c. I also write a read me how can you flash it and root your phone with CWM. Well it was not tested as well, I am 98% sure it works, because rooting p990 and su660 stock roms works that way and p990, su660 and su880 almost the same. I use the CWM recovery image from "CWM for v19c".
My folder is here, some files are still uploading. I will notice you in this post when it is finished
There is no bootloader.img in the folder "SU880_V20C_CWM".Have you forgot it?

[Q] Help! LG F180L has been bricked, only google logo,no Download&recovery

HI~
could somebody helps me~
my situation-
I have LG F180L (korea version, 4.1.2)
few months ago, I flash it to 4.1.2 Taiwan version ( v10F) with KDZ updater.
it's successed!
(I backup original F180L's base-band and restore ,
some days past, I found something wrong---
* Standby-time not to long,

so I want to go-back to korea-version
But I can't into download-mode (volume UP&DOWN + plug USB to PC) ,
and recovery no-functional-list (it's only green-droid with triangle)
and then, I install freegee on google play store , unlock BL & install CWM 6.0.4.8 recovery
reboot into recovery (worked!), clear user-data & cache first
(no download-mode ,so I download a (universal 4.4.2 v30c) zip package on gfan web-site, and copy it to my F180L
zip-file source: bbs_gfan_com/android-7520119-1-3.html)
then install zip from SD
everything in install-process looks so good,
But ~ reboot,

[Unbrick] How to revive H815 - no recovery/fastboot/download mode

Today something went wrong while flashing weekly LOS build and my LG G4 (H815 with v20P firmware) went into very fast bootloop: https://www.youtube.com/watch?v=9gm0dh6bLp4
In this state i wasn't able to enter recovery, nor fastboot, nor download mode. Only IMEI screen (Vol Up + Vol Down I believe) was accessible which was no use.
Here are the steps which got me out of troubles:
A) Verify that you have LGUP installed and have proper 8994.dll version for your device.
Different versions of FW use different libraries which results in errors during flashing.
Steps:
1) Install LGUP with this guide https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
2) Get the right DLL. You can try this one:
Abandoned War Place said:

error 0x2000 invalid command response Has Been FixeD WITH THE LASTEST DLL FILE
FILE INCLUDE (DLL+PATCH_DLL+SETUP LGUP+DRIVER) package
Please Read The *READ ME FILE FOR THE RIGHT INSTALLATION WITHOUT GETTING ANY PROBLEM :

https://drive.google.com/file/d/0B_yWw6RLoA-gdTMtZFczMUhQOHM/view?usp=sharing
Click to expand...
Click to collapse
...or extract it directly from KDZ file with extractor https://forum.xda-developers.com/showthread.php?t=2600575.
You need to extract it from FW version that your phone is already running, not from the one you are about to flash! (when flashing from v20d to v20p you need v20d version, but when reflashing v20p FW you need the v20p DLL)
3) Navigate to LGUP install folder (default "C:\Program Files (x86)\LG Electronics\LGUP")
4) Overwrite the old DLL located in "model\8994" folder version with new one in
I don't know the exact compatibility, or how many different DLL versions are out there. Hopefully it doesn't brick the device even more when wrong version is used, it just doesn't work.
B) Write h815 image to sdcard as mentioned here:
leptdre said:
Hi guys,
i came up with a temporary to unbrick LG G4 H815 , you just need a 32 GB SD card ( i used Sandisk 10 class) , the dump that i will link , and Win32 disk Imager, the SD card must low level formatted.
1- download this dump

2- put the SD card in the PC and chose the dump file and write ( run as admin ):

It worked for me with just 8GB one. Be aware that the image written to SD have like 20 partitions so windows might go crazy.
C) Follow these steps:
jam1445 said:
3. One the Write Completes. Eject Card and insert in your LG G4 H811. Press Volume Up Button while connecting the USB Cable.
4. There you go, it will open the download mode.
Click to expand...
Click to collapse
D) At this moment my G4 finally entered Download mode
I was able to reflash KDZ using the usual procedure (select UPGRADE, find a KDZ file, restart LGUP, select REFURBRISH and START). Initially I got 0x2000 error at approximately 16% (boot displayed as status) that was caused by old version of 8994.dll library.
E) Back to stock
Now you should have stock H815 again so lets flash LOS back as usual
Kudos to OPs: @bullghost , @shakeyabooti , @leptdre , @jam1445 and other posters on G4 section of XDA!
Hope this helps someone!
Good job. If your using this and you're gonna buy a SDCard on purpose, be aware that this fix might not work on your device. Ehehe
@Jirrick im getting the same error on LGUP where do i find a newer version of the dll?

I'm using a 16gb microsd, but however I try to image it (exfat, fat32 filesystems, different win32imager versions) also have tried different cables, but it still doesn't show any sign of life. I bricked it exactly the same way as OP did. Does anyone have anything else I could try to fix this? Also does the battery charge when its on 9008 mode?

Can you get at least to the IMEI Display mode (Vol UP and then quickly Vol DOWN, keep both pressed until it shows up)?

No could it be caused by low battery? I remember it being like 30% when I bricked it, and does it charge under 9008 mode?
Sorry to hear that. I'm afraid this is beyond my knowledge if it wont even enter the IMEI screen. I suppose you can leave it bootlooping in charger over night and then try in the morning?

It does not bootloop, straight up dead. Just shows 9008 forever on the pc, I left it for like 2 hours like that yesterday. I'll leave it overnight today and if not I'll hack up a direct 5v 1a charger to charge the battery directly. If both don't work i'll probably flash LS991 files in QFIL and use it as a tablet afterwards.. damn i got this phone not even 2 weeks ago perfect condition and all. Will not buy any more damn LG devices.
Oh, I thought your phone was rapidly bootlooping like mine did. Sounds like the person who sold it to you was aware that the phone is on last legs (probably even baked the phone so it runs for few days more) and screwed you over. My next phone wont be LG either.

Lenovo K8 Note Red State Bootloop After Flashing Custom Recovery

Hello Guys,
The issue is that i wanted to root my lenovo k8 note so follow this link "https://forum.xda-developers.com/android/development/tutorials-how-to-root-lenovo-k8-note-t3685502", Everything works file but in last rooting step no. 9
9. If you see internal storage 0mb Then GoTo Wipe and FORMAT DATA once & reboot to recovery
but in my device there has memory 59999mb so i ignored and reboot using twrp but it says no OS installed
and shows orange state, then i format phone using twrp but nothing happens again orange state and no os installed.
then i found another article with same issue "https://forum.xda-developers.com/android/help/lenovo-k8-note-stuck-boot-logo-flashing-t3751324/post75974342#post75974342" and found this
The bootlogo issue.
Hey! I read your post regarding your k8 note being stuck at the bootlogo.
Consider that you can still use TWRP, boot into it.
Then go ahead and download the SuperSU zip on your PC/laptop and connect your phone with a USB. You might be able to see the SD card folders on your PC, then you can just copy and paste it to the internal sd and flash it. You'll be good to go. If that doesn't work, in the TWRP Mode, go to advanced and select ADB sideload. You can now flash using ADB sideload.
Search for tutorials on ADB sideload. It's easy and that should work.

Are you okay with losing your data on your phone? If yes then go ahead and flash stock ROM with sp flash tool. And about your problem, I guess you wiped the /system partition as well that's why it was showing no os installed.
Another thing is that if you install twrp Do not boot up your phone, boot up into twrp by pressing volume up and power button at the same time you'll need to flash magisk or supersu so that twrp can modify partition correctly.
Thanks

I have lost all my mind and need serious help.
Recently, the march update came. i forgot that rooted phone should not be updated by the OTA update. And i did. As a result i got stuck in a bootloop. Then I had to use the oreo ROM from this forum and flashed it using SP Flash tool. It was a successfull flash. Then I used Maui META to write the IMEI for both sim. That was successfull too(Wifi and bluetooth addresses were working by themselves and i didnt write the serial number of the phone).
After working nicely for three days, i was using Whatsapp and a friend of mine sent me a .pptx file (powerpoint presentation). I opened it using WPS office app. I opened it multiple times in morning with no problems. But in the afternoon at about 2.53 PM while i was in my car, i was unable to open the file. The phone hanged. It heated up. To get out of the hang, i restarted the phone using the power button. IT DID NOT START. All it showed was the lenovo logo screen. And after doing more restarts, the phone went completely blank.
Now i cannot start it, or charge it. So i thought of flashing it again. But when i connect it to my PC, it keeps CONNECTING and DISCONNECTING. what i saw in the device manager was that the driver keeps changing very fast betwee MTK USB PORT and PRELOADER.
I found the solution to be updating the drivers manually. I did. Now the driver shows only DA USB VCOM and when it changes, it goes invisible in the PC and then appears back. Now when i start flashing, the first red progress bar appears as: Download DA 100%. and the flash hangs. After some time, this error will popup: ERROR: STATUS_UNKNOWN_STORAGE_TYPE (0xC0040009)
Please someone help me.

I opened it using WPS office app. I opened it multiple times in morning with no problems. But in the afternoon at about 2.53 PM while i was in my car, i was unable to open the file. The phone hanged. It heated up. To get out of the hang, i restarted the phone using the power button. IT DID NOT START. All it showed was the lenovo logo screen. And after doing more restarts, the phone went completely blank.
Now i cannot start it, or charge it. So i thought of flashing it again. But when i connect it to my PC, it keeps CONNECTING and DISCONNECTING. what i saw in the device manager was that the driver keeps changing very fast betwee MTK USB PORT and PRELOADER.
I found the solution to be updating the drivers manually. I did. Now the driver shows only DA USB VCOM and when it changes, it goes invisible in the PC and then appears back. Now when i start flashing, the first red progress bar appears as: Download DA 100%. and the flash hangs. After some time, this error will popup: ERROR: STATUS_UNKNOWN_STORAGE_TYPE (0xC0040009)
Please someone help me.

I couldn't find more about the problem online, can you please upload a screenshot of the error. Try using the latest version of SP Flash Tool and see if the problem persists
I have lost all my mind and need serious help.
here are the screenshots. Note that the battery is in the phone always because i am unable to open the back cover. During the flashing process, i did not press the vol - button.

Now in the following screenshots, i kept the vol - button pressed down. Note that the driver is stuck at preloader and not DA. Also the first bar is yellow color in both these cases. However, in the above situation, multiple files were flashed. But in this below situation, only this so called "flash" was done; that too unsucessful in the end.

The problem may be with your drivers, i see you have Preloader drivers only.
Follow this guide for installing drivers - https://forum.xda-developers.com/elephone-m2/help/windows-10-mtk-vcom-usb-drivers-32-64-t3267033

So i did as you said brother. I don' t know how but something happened. The phone, after a long time actually displayed up. It showed the LENOVO logo and down in the corner two things came in written :
>device unlocked
>Tool DL image Fail
I googled it up and found that it requires to flash the phone with the DA DL option ticked. I did that but it does not flash. The error is same as follows:

Okay so what i figured out is that in this state: (battery plugged in, no notification LED response, no response on power or volume buttons) the driver you require is MTK USB PORT.
I updated to this driver manually, and guess what? the phone actually flashed. But three files remained and the process hanged. (system, cache and userdata)
Now i get the errors:
>device unlocked
>Tool DL image Fail
and sometimes: >device otp failed
I am trying to flash the rest three files individually. Lets see what happens.
