[SOLVED] Need to flash System partition through fastboot - LG Optimus L9 P760, P765, P768, P769

[SOLVED] Need to flash System partition through fastboot - LG Optimus L9 P760, P765, P768, P769

Hello.
I recently sold this phone and went to factory reset. no problem. However, i forget i deleted the STOCK home app. THere is no launcher on the device so LG Setup Wizard simply crashes when finished setting it up. There is NO ADB since the setting has been erased. I need to re-enable it in settings but can't get that far since LG Setup Wizard keeps crashing..
I think i'm screwed.. what a stupid way to brick..
Device is: LG Optimus L9 P769 T-Mobile variant. Thanks guys!

you should be able to put your device on download/emergency mode and flash a kdz file with lg tool, you tried it?
if don't try yet, take out your battery, hold + volumen botton and put your battery again holding even + volumen key, and conect your to your computer, it must show the yellow screen with the legend download/emergency mode, and in your computer must be install the drivers, to exit the download/emergency mode just take out the battery or hold the power button, and for flash a kdz file, search a tuto, there are many, and many videos to make it easy . All this process let your device as new, all applications and configurations

I am aware of that mode but when attempting to flash that way before, after upgrading to jellybean, it would never flash for me. So I didn't even try it. I'll give it a shot though. I also was able to download one of the cwm backup zips posted in the other thread and extracted the system partition then created a .img image out of it and will try both your method and flashing that img file when I get home from work. Thank you for your post!

SOLUTION
Installed the ICS uboot.
Booted to SW Upgrade mode via plug USB, hold volume up button, place battery into device
Launched KDZ update tool and it connected and went smoothly!
If you have the JellyBean uboot, it won't connect in SW Upgrade mode if booted manually.

[Q] Bootloader Encrypting Error | L9 P760

Yesterday I rooted my LG Optimus L9 using LGpwn tool, after that it worked just fine.
This morning I tried to install ClockworkMod Recovery. Using this post. It explains how to download and install CWM Recovery from app that you downloaded in form of APK.
This method did not work 100%, but I was able to reboot normally, so in post it said that sometimes it does not work and you need to download and use Busybox installer Link to busyboxx.
After this I managed to boot in too CWM using app from mentioned thread.
Then problem occurred. After I saw CWM was working I selected reboot device option.
Except now when it started to boot it stops right after Second LG logo (First is static one second one is animated).
I get white screen with "Encrypting" on top and gray line. And one Reset Phone button. IMG they are Dropbox links.
This is followed with Error : Unfortunately, the process com.android.phone has stopped. IMG
I am able to boot in too CWM and I have tried flashing something like Cyanogenmod but I get error Status 7. Tried removing line that checks model, no use.
Tried clearing every cache and fixing permissions, nothing. Formatted everything still no use.
Dear XDA community That you in advance.

I fixed my phone by going into SW upgrade mode, and using the Upgrade Recovery function of the LG Software Update tool or whatever. Be sure you don't have any http servers open

I got the same problem, but when I try to access to SW mode and connect to LG Software Update tool to restore my phone, the phone keep disconnect and the phone screen will turn off, so I fail to restore my phone, I have already re-install the USB driver and changed a several USB cable but the problem still, but I tried to restore my phone with SW upgrade method since last night and is was OK, can anyone help me?
---------------------------------------------------------------------------
The Problem Solve Finally, the solution is I plug the battery back to the phone after access to LGMobile Support Tool, and after finish the restore process, the phone will restart but keep boot loop, then I perform the hard reset (Remove the Battery and insert it after few seconds. And now do the 3 button HARD RESET. First press VOLUMEDOWN and HOMEbutton. Then Press Power button only for 3 seconds and release power button but dont release VolDown and Home button and KEEP BOTH PRESSING until you see a Bigger Green Standing Android and circulating Molecular structure above it. DONE! ), then the phone begin work~~~

Hi,
I HAVE GOT A VERY BIG PROBLEM.After i installed the App AutoRec(i had TWRP befoe,but i thougt when i install it it updates TWRP to a newer version) my phone only starts in Fastboot Mode-no DownloadMode-no Recovery Mode.
After that i erased all the things(aboot,boot,cache,system,laf,....) und flashed them again,after that the Phone only starts until the LgLogo then it stops.No Fastboot,no recovery,no DownloadMode.When I Press VolumeUp+PowerOff i get into the Factory Reset.When i press on Erase all user data&restore default settings?---When i press Yes the phone the logo comes an on the left up side stands"Error:boot ceryfication verify
Secure Boot error
Cause :Boot cerification verify
After that the display is black,and i have to restart the Phone.
When i press all 3 buttons on my phone,i got into the hardware key control mode,does me help that everthing?
When i plug in the phone in my pc,it says "unknown device",when i use to do something with fastboot it says"waiting for device"?
Please help me,what can i do?I have the Phone only since 2 two days,an i wouldnt lost it Unhappy
Sorry for my bad english

Can you still get into twrp? With the phone off hold power and vol down til LG logo comes up the release and press again after. Should take you to a menu, just hit yes. If it takes you to recovery just hit factory reset and it'll,take you to twrp. If so, I'd recommend putting a Rom onto an sd and flashing it. You'll lose everything but it's better then losing this beautiful phone

You obviously didnt read his post correctly. He stated that when he gets to the factory reset area which leads you to Recovery Mode/TWRP it shows the LG logo appears and nothing happens.
As for you my friend if you are able to somehow get into download mode with a button combination you have a chance at saving yourself by using a TOT or KDZ file to restore your phone to stock software. But i also have a question for you.........Why the hell would you allow an app to flash a recovery file that has nothing to do with BUMP'D? The Bump'd recovery for our phones is specific to our phones! You should never auto update any recovery unless stated its ok from the Bump'd developers, Which they never did or will because our TWRP Recoveries are different than any other phones because of the bump'd implementations with in them and the boot.img's. Sounds to me like you may have screwed up your partitions and/or boot stack. Your are better going on IRC and requesting the help of TheCubed/IOMonster and AutoPrime, but mark my words you will face some heavy criticism from members of the IRC channel when you explain this story to them. But they are always willing to help.

I dont know why i have done it,im new on Lg.Before i had an HTC there is so many other.I will aks that guys.I hope i can save my new phone.
But the Problem is,i dont get into download Menu,i did everthing

Bootloop and no way to enter in recovery or download mode

Hi guys! Yesterday I decided to unlock the bootloader, flash recovery (twrp 2.8.6) and the cyanogen 11 nightly. Everything went good until I tried to install the gapps, I noticed that the physical shortcut to enter in recovery (after the turning off, of course) didn't worked: the phone restarted or boot up the rom, but I was able to enter in recovery from the advanced restart menu from the rom. Going into the info of the phone where it says kernel there was written "unknown" and no way to overclock. So I decided to reinstall the kernel (the cyanogen11extended) from twrp, everything went good except that I couldn't restart into recovery, it stuck on rebooting until shutdown. So I tought let's use fastboot to erase ad flash the recovery partition and the kernel, but it didn't do anything even if on the cmd said okey and finished in something about a second, but when i tried to enter in recovery I always get stucked on rebooting. So I tought"well if I have the system image I could flash it with fastboot and restore the stock kernel", so I erased the system partition and tried to flash the system.img and I get the message that it is too big for the destination device. Now I don't have a system installed tye hotkeys don't work and I'm stuck on LG screen logo.
There is a solution or do you suggest to send the device in warranty, instead?

Pull the battery and try to enter download mode.

Hi vagelis! You mean without the battery? The hotkey is vol up+power, right?
Edit: i tried without the battery pressing the vol up + power (also tried with vol down + power) and it doesn't work, on the screen I have an image which says to put the battery in, and holding the keys has as only result to reboot the phone showing the image... I guess there's no hope right?
Edit2: I entered download mode using the g2 method, now I have to downoad the kdz rom and the lg flash tool to unbrick, right? But where I can download it since the lg site for the firmware is apparently down?

Ok guys, I was able to unbrick entering in emergency mode e doing the flash tool stuff. The strange thing is that when I start the flash tool putting the file kdz and going forward in the next window, when I click on read phone info the program stops working, if I click directly on stuff then the lg mobile support tool is opened. Now when it starts to write on the phone, the tool says that an error occurred (something like "the server is offline) but on the phone it says the port com and start to download the rom. If I say ok to the error of the lg mobile support tool it stops the firmware update and stops the program, if I don't click ok the firmware update end is work unbricking the phone.
Now I noticed that with the stock rom from the version v10h until the last one towelroot is not working, so I downloaded the v10g germany version (since the italy version was offline) and flashed with the same procedure as I have done with the unbrick, so I could run towelroot and flash the twrp and the cyanogenmod11. Thank you so much for your time!!

The topic is quite old, but I've just solved that problem. You should just do it:
1) hold power and vol down till you see LG logo -- immediately release these buttons and 
2) immediately hold power and vol up button to enter into factory reset menu. 
Then click "yes" and next "yes", too.
That's all.

Tab S6 stuck in bootloop, can't get to recovery mode

My Tab S6 tried to auto-install an update yesterday (it is rarely connected to Wifi/internet). It then rebooted. Since then, it's been stuck in a boot loop.
It will display the "Samsung Galaxy Tab S6 | Secured By Knox" logo screen for a few seconds, then switch to the blue "Installing System Update" screen (with the android logo). Installing System Update gets to 28% and stops. Then the rotating icon on the android freezes. Then the device reboots and starts all over again.
Edit: the tablet is 100% stock. It's not been rooted or had any custom ROMs loaded.
I have tried getting to recovery mode, by holding power+volup while it boots. This doesn't seem to change the behavior at all. Any advice is much appreciated.

can you shut it down? try volume down and power button ? if it don't shut down, do this soon as it reboots, hold volume up and down and plug in usb cable to desktop/laptop usb port! it will boot into download mode!

I can't actually shut it down. If I start holding power+voldown right after it boots, the tablet does reboot before getting stuck at 28%. But it reboots--it doesn't power off.
I tried download mode and that actually seemed to work! Specifically, I left the tablet overnight in the reboot loop until the battery drained. Just now, I held down volup+voldown and plugged it into my laptop. I got the green "Warning/Custom OS" screen and then pressed volup to continue. The tablet rebooted pretty quickly after that (I'm guessing due to low battery) so I didn't get a good look at the download mode options.
Once I'm in download mode, can I factory reset the tablet? I don't need to preserve any data/apps/settings.

You cannot reset the tablet from Download mode afaik- You need to enter Recovery Mode to do that.
You can however, flash stock from Download mode using Odin (3.13.3 is best). If you're not confident with doing that, your best option is Factory Reset in Recovery Mode. Hold Volume Up and Power when the Tablet is booting, let go when you see the Samsung logo. The timing can be tricky, but you should be able to do it. Also, you can force a reboot with Volume Down and Power.
Alternatively, if factory reset doesn't work, since you're completely stock, you will still be covered under warrenty.

Thanks for the suggestion. I have tried this many many times. I've tried letting go of the buttons at different times. I've tried holding volup while letting go of power. I've tried this a ton of different ways, and no matter what, the tablet always shows the "Installing system update" screen. Some googling has led me to believe that sometimes, when performing a factory reset, the "Installing system update" screen shows up right before the normal recovery screen. Is it possible that the tablet is trying to get to recovery mode, but can't get past this first step?

Honestly, I don't know - I'm not an expert but I guess it's possible that the update failed and corrupted both System and Recovery.
You'll be covered under warrenty, so maybe just return the Tablet from where you purchased or direct to Samsung, could take a while given the current situation though I guess. If you have a PC, then I think the best option would be to just flash stock yourself, since that's probably all Samsung will do. Even if that doesn't work you'd still be covered under warrenty, as far as I'm aware attempting to flash stock doesn't trip Knox.

Here is solution to unbrick your device!!!

Despair not...I have just come from resolving this exact situation not 30 minutes ago. I'd been trying to flash (using Odin as I decided to stay on Stock and not root this device, for a change) the latest OneUI2.1 releases for my device (SM-T865 - LTE version) and boom in the middle of the Odin update, the flash just failed...I then couldn't reboot and get into neither Recovery, nor Download Mode because it appears my bootloader and recovery both got corrupted.
Here's what you need....
1. Odin app for PC (am on Windows)
2. Your device's Stock firmware (sammobile firmware archive)
3. You will need someone to help you boot the device directly into Download mode (and this is the tricky part because for most of us we are used to get into Bootloader by using the key combination (from Powered Off device) Vol+ and Power On at the same time to get into stock recovery and then scrolling down to option 2 in this menu, "Reboot to Bootloader". Well now you are going to boot directly into Bootloader mode. Here's how you do it...
4. Get your friend to line up the USB-C cable into the port of the device, but DO NOT press it in...yet
5. Press Power off and Vol- buttons at the same time to turn off the device
6. And now you have to to be super fast: if device starts to turn on on its own, YOU press and hold Vol+ and Vol- both at the same time while YOUR FRIEND pushes the USB cable fully into the port - you should now have booted directly into Download mode. (if not repeat this, and remember to be super fast and sync with your friend pushing in the USB cable)...
7. When you get into Download mode, then you are home and dry...
8. Select ONLY the Bootloader file (BL...XX...) in Odin, make sure only "reset time" and "reboot" are ticked, and flash
9. When device reboots, press Vol+ and Power combo to get back into Bootloader mode again...but I think device will reboot into Download mode on its own
10. Now select all the files from your Stock file into the various tabs (BL, CP, CSC, AP...) do not select HOME_CSC as we want to flush this device clean...
11. Flash, and voila...success - you will have lost all your data but rather that than losing the device...
12. Feedback here and let us know if this works? For reference for others in the future...

FYI, I got in this situation, and the previous post did work for me, just takes good timing! Thanks!!!!

Same issue today for me. My tablet showed different screen with green and red text, it allowed me to delete app data, then booted into safe mode, then i had to do factory reset and now i am screwed, as it is refusing to restore any apps and their settings. I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.

Just found a news article that there is a RGB/sRGB problem with wallpapers. It might be the problem i had.
I am adding a screenshot of the result.

Yeah, I had that kind of reboot loop from a wallpaper that I downloaded

I can get into download mode. But it kicks me out within a few seconds. Any help please

I have the same problem with a Tab S6 Lite, it is in bootloop and does not let me enter the recovery mode, I can go into download mode and I flashed the latest original firmware Android11, Android10 etc., . I tried them all but always goes in bootloop, and also the bootloop occurs only if I connect the usb cable to the PC, without any sign of life. Do I still have hopes or have I compromised the motherboard?
The reason for all this is because I had followed a guide to give root permissions with magisk, I did everything right, only that the guide was with Android10, while I had Android11 and I was deceived by the fact that in the title of the guide there was written "guide 2021"
, so I did not check the compatibility of operating systems, I was a fool, I know, I hope so much that I did nothing irretrievable, it's my son's tablet!

Download the android 11 last rooted rom from there. You install it with odin as as a normal original rom.
Disable in odin auto reboot. After rom install, restart manually and press the correct buttons immediately to boot in Twrp and not to system. Format (not wipe) data from there and reboot to system. If you are lucky it will work..
(I hope you unlocked bootloader before try to root. If you haven't unlocked bootloader this won't work also).

I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.

Wiping cache partition in Recovery and reflashing the firmware are basically your only 2 options

Flash in odin the same rom you had. There are 2 csc files in rom, which you use 1 in odin one. Try use the "home csc". Home csc keep KEEPS your data. If you're lucky it may work. (It would work in keeping your data 100% if your rom was ok. Because it isn't you have some changes to work.).
You must try with same rom or newer.
CSC – If you flash the CSC file, it’ll perform a factory reset of your Galaxy device and wipe all data while installing a new firmware to bring your device to the same state as it was when you purchased it. Go with CSC if you want a clean installation.
HOME_CSC – On the other hand, if you want to keep your Samsung phone’s data and settings even flashing the stock firmware, you can select the HOME_CSC file.

LM-V600TM stuck in the boot loop

Hi everyone, I followed this guide here https://forum.xda-developers.com/t/v60-bootloader-unlock-and-magisk-root.4358785/ to root the phone with magisk. Everything went great up to the last point. I rebooted my device and I am currently stuck at fastboot mode as my device can't normally boot into stock rom I had before I tried to root it. Should I just flash stock rom on the device? How should I do that? I am still an amateur and can't figure it out by myself. My bootloader is unlocked. Any help would be much appreciated. Flashing backup boot images doesn't help.

Just put your device in the download mode. Here are the steps for you:
1. When you are in the fastboot mode, choose to turn off the device by scrolling though the options (via volume up/down key and then pressing the power button to select).
2. After the phone is off, keep the volume up key pressed and insert the USB cable into the device. Make sure the USB cable is attached to a computer before plugging it into the phone. This will put you in the download mode.
3. From there you flash the relevant firmware using LGUP.

The case is outdated, I managed to upload the firmware via LGUP
Hi everyone.
I have a similar problem. I wanted crossflash to EU.
When I was ripping and deleting the contents of the partition, the phone lost the usb connection and after reboot it fell into a loop. It does not report for usb and I can not turn it off. Is there anything else that can be done to save him? I erased the partitions FTM, Modem_A, Modem_B, SID_A, SID_B, OP_A - not OP_B.
I have a backup of them
I'm sorry, my english is bad.

You have two options depending on which one is available to you:
1. If you get into the QFIL then try to restore the deleted partitions. It is quite possible that other partitions have also got affected due to abrupt disconnection resulting from power failure.
2. Maybe you can get into the download mode. It will be tricky. Press and hold the volume down key and the power button till the phone restarts. Once it starts, press the volume up key and insert USB cable (that is already connected to a computer). Once there, re-flash the firmware.

Thank you for your help. I was able to start the phone in download mode and upload the firmware via LGUP.

Hello! I didn’t root anything, everything is stock. at some point phone just crashed and now it is stuck in boot loop. i was able to factory reset it, but nothing changed, it keeps rebooting. LV600AM

The problem, in your case, becomes complex because AT&T does not release firmware publicly (that you could just re-flash the phone with). How were you able to factory reset the V60 phone? Did you get into the settings menu and reset it from there?

i was able to use power/volume down feature to get into factory reset menu, wipee everything, but nothing changed. it just keeps rebooting till battery runs out

I hope someone here could share with you a full AT&T V60 partition dump. Failing which your only option is to have AT&T restore it for you.
