[Q] p769 bootloop, can't go into CMW mode - LG Optimus L9 P760, P765, P768, P769

My p769 was unlocked bootloader and installed NamelessRom with CMW 6.0.4.5.
I installed Rashr app from PlayStore to install CMW 6.0.4.8. I followed and used files from
p769-recoveries-p769-mirror-issues-t2879854
After installation, the device rebooted. But LG logo shown less than 1 second, and the keep rebooting again again. I tried to go to CMW mode or hard reset, but it doesn't work, just bootlooping very quickly.
I followed a tutorial, FLASH Any LG L9 Factory ROM (kdz) WITH OFFLINE FIX but,

Drivers installed correctly and followed the instruction correctly. Even my device can't go into CWM mode, I can turn it into S/W upgrade mode. But as shown in the picture, there is a connection problem. I tried this using two different computers, but same problem.
I also tried to re-install CMW using fastboot. Used this http://forum.xda-developers.com/showthread.php?t=2119090 tutorial, but stuck at
If I put in battery, the device turn on and start bootlooping. (LG logo is disappear very quick). Run the fastboot again, and tried to this, http://forum.xda-developers.com/showpost.php?p=43969494&postcount=95 but I same problem. cmd window shows <waiting for device> and there is gray color of LG logo in the device screen. After a few minutes, device rebooted automatically and the bootlooping. No flashing job processed.
So, my p769 is totally dead? Anything I can try to do?

Nevermind

Solved the problem.
I used LG FlashTool and could flash it to normal stock rom. Now it boots OK, and works OK.
Used Unbrick/Unroot/Flash ANY (P769, MS769, P760) in Download Mode tutorial,
but had some problem with files that I made and / or come with package.
So used files that BajoPrimate uploaded. Flashed successfully.
Thanks sammyz, BajoPrimate

Hi, i can't help you for now, but i have your same smartphone and i want to make a cwm recovery.
I've been rooted succesfully the phone and i made a cwm for this device, does anyone know how put the you25 in fastbootmode?
*deleted*
your help will be apprecciated,
the phone if of my girlfriend and now, after tryng to flash a cwm recovery built by the online builder,the you25 is still in bootloop.
Fortunately, I made a backup of the stock recovery and now i have to reflash it.
I need to know how put the phone in fastboot mode or eventually how reflash all the entire system, (before my girlfriend knows what i did:crying.
If you are interested, i made a cwm porting that works for 50%, you can backup and restore all entire system; then i tried the online builder to make it 100% working but with no success.

No, i can't access adb, i need to put it in fastbootmode by pressing at startup a sequence of buttons. (Es, power+vol down or whatever else for this devise).
Now i see the android logo only plugyng the power cable, it still appears for about 3-4 seconds, then the backlight of the three buttom buttons lights on and then the device reboots.
Initially, I flashed the recovery by adb, after rooted the mobile and mounted the filesystem in r/W mode with:
Code:
dd if=/sdcard/recovery.img of=/dev/blocks/mtdblocks10
.
You can find the right number by typing in adb shell:
Code:
cat /proc/partitions/
I have experience with other device, generally you can flash with adb, fastboot and by download mode, if the device boots you can always fix it, but you need the right tools.

what happens when you boot the device by normal start, does it also go into the 3-4 seconds bootloop or does it get stuck on the android logo?
i had my device stuck there already too but i was still able to access adb.

The device starts only if i plug the power cable, after 5-6 second the android logo shows up and then after 4 seconds the device reboots.
Adb doesn't work for me, but if you have adb working i think i can help you.
What is the last think you made to the device before beeing stock on the boot?
*deleted*
Thank you, but that doesn't work for me.
What about jtag? i have experience with decoders but nothing about smartphones.
Reading about how restore nexian a850, i founded that is possible to reflash the you25 with the sprocoom tool and the same driver of the nexian a850. Unfortunately I do not have the firmware for the you 25. Has anyone it, please?
I think that it is possible to flash the device using the img files that i created before and a prebootloader.
I have also to edit a file with a list of all partitions with their address in hex format.
Unfortunately i do not know these values, and i cannot see them from my device because it doesn't work. can anyone help me, please?
here is a list of all partitions:

[Q] Device ROM/Soft Bricked problem! Help!

I've spent some time researching how to root my phone for quite awhile now because there was almost no guide for my phone to be rooted. I have a Samsung Galaxy Admire 4G (Model SCH-R820) connected to MetroPCS with a 16 GB external SD card inserted. Also it had Android 2.3.6 installed on it. With some hard research I finally found a forum that I followed to root my device.
The forum actually did help to root my phone which I couldn't believe. :laugh: I installed the .apk file with File Explorer and installed Framaroot, then I opened the app and I rooted with SuperSU as instructed in the forum. The whole process was successful and I downloaded a app to determined if my phone was really rooted which later said positive that my phone was rooted. After less than 2 hours of my phone being rooted and having fun with it, I saw thing about custom roms and I liked the ideas of installing a custom rom. I installed a app called "Rom Manger" and it said I needed ClockWorkMod Recovery or ClockWorkMod to be installed to be able to get the custom rom. My device was NOT supported and taped the unsupported device selection and it prompt me to say if I had ClockWorkMod Recovery MANUALLY installed. I didn't know what that mean't and selected "YES" which I would regret later on. I then selected "Backup Current ROM" and it restarted my phone but I don't know where if the backup was place on my internal memory or SD card (I THINK IT DID NOT DO A BACKUP). I went onto my computer to get a custom ROM and tried to install it into my phone using Odin v1.87 when my phone was i guess in "download" mode. (When you hold a few buttons and it prompts you about a warning on installing custom OS).
Just when I saw it fail to install, I realized that I installed the WRONG ROM to my device! (THE CUSTOM ROM WAS FOR A DIFFERENT DEVICE). :crying: When I restarted my phone it was stuck on the Samsung Boot Screen and it would not boot the Android OS and would get stuck on the Boot Screen whenever I would restart my phone. I tried Wiping Cache, Wiping Data/Factory Reset, and Rebooting my device and the same problem would persist. Also the app "Rom Manger" didn't seem to install ClockWorkMod Recovery because I'm only able to do Stock Android System Recovery and "Download" mode to my device.
The thing I think I can do is get a stock ROM for my Samsung Device and reflash it with Odin but whenever I research the ROM for my device I can't seem to find one EVEN on this site. (TRUST ME I DID LONG RESEARCH TO FIND ONE). My brother has the SAME EXACT PHONE and I was hoping if I rooted my bro's phone and do a backup on my bro's ROM with a different app (NOT ROM MANGER) and get the back up on my computer and use it on Odin to reflash MY PHONE'S ROM would it fix my BootLooped/Softed Bricked phone?????OR any ideas on how to get my phone back working OR do I need to buy a new phone if all possible solution fails?
One more thing...I think ClockWorkMod is NOT Safe for my device so if I really need to install it on either phones please tell! :good:
This is how it looks when in download mode (Sorry For The Huge Picture):

I did the same thing. try sending it into metro pcs they told me they would flash the original on there. they wouldn't do it for me though cuz i cancelled my service with them and got t-mobile with a galaxy s3.

LG L9 P760 Softbrick - no way to flash etc.

I have very big problem with my LG L9. Firts, I unlocked bootloader and rooted phone with some kind of method, everything was working great, until I flashed PACman rom. Internal space was decreasing to the moment when it reached 612kb, so I wanted to flash another Rom. And from this moment I have problems.
First of all, I downloaded rom, for example PolishBlood from Original Android Development.
I entered Clockworkmod (6.0.3.1), wiped all data / factory reset, dalvik cache. Did everything like in tutorials. Then, clicked install rom from sd card and pick "choose zip from external sdcard", cause this option was working when I was installing PACman. And here I have problem: E:Can't mount /external_sd/. I read couple of tuts, and best, and I think only option was/ still is guide from this thread: [GUIDE] [UNBRICK][ROOT] FLASH Any LG Factory ROM (kdz) WITH OFFLINE FIX
But here, I have problem too. flashing process stopping at 15%, and telling me that cable/cellphone is disconnected.

I think I have all drivers installed, I'm doing everything step by step like in tutorial, except enter in LG software mode, cause I don't have any rom.
So for now, I can only enter ClockworkMod and S/W Upgrade mode. Please help, cause for now I have Nokia 3120 ;/

Do online kdz flashing using lg mobile support tool. Download it and connect in S/W upgrade mode . It will detect your phone , then upgrade to latest version. Its online method so make sure u remove those two lines from host file which v use for offline flashing. This should work
Thanks a lot. It was simple, why I didnt think about that? Problem solved.

Stuck on "Powered by ANdroid", No Recovery or eRecovery

I tried to upgrade from 7.4.16 to 7.5.1 by creating a flashable zip from huawei update extractor, and the zip file created by it include modem.img to flash to /dev/block/mmcblk0p30. so when i reboot it, the phone will stuck in Powered by ANdroid splash screen. trying to boot to recovery mode won't work. but by pressing vol+ vol- and power key, i can enter recovery mode, the stock recovery will try to flash sdcard/dload/update.app, but will fail at 5%. the twrp recovery is working but flashing normal zip including system, boot, cust won't help.
So one day I was searching how to flash modem.img and found out dc-phoenix tool can do that for honor 8. so i gave a try.

the tool is not free, i have to pay eur 15 to get a account to unbrick it. since huawei customer service costs about eur 8 in my area, i think its worthy.
To ensure, i try method 2 of it. this needs to download a factory image for my phone, click Enter Support area a web page will open, find firmware of my deivce, whick is
PLK-AL10_CM001026_Factory_firmware_general_Android_5.0_EMUI_3.1_testpoint.dgtk
my phone is already in fastboot mode, just connect it to pc, click update waiting...
after a long waiting finally its over, no error.
i use fastboot reboot to boot it and it just boots fine. so the phone is unbricked, but system is not useful, model became unkown. the factory version is emui 2.0, i can not upgrade to newer version.
so i need to try method 1 again. this time i downloaded emui 4.0 b388 from club.huawei.com, load it.
at first i used a wrong version for another phone model, it will always fail, so its important to make sure the rom is full stock one for the exact phone model. if third part adb/fastboot software exists, close them first, lick wandoujia, hisuite, qq... then click update to start.
when its ready, my phone can boot up fine with emui 4.0, but sim card is not working, so i had to continue the step 2. reboot to recovery with usb plugged in. this step was a lot slower then step 1 but just wait patiently.
At home this step always fail at writing file 21 of 22:System instantly, showing out of memory which is not normal since my pc
has 16g memory, and hard disk still has 8g left. But on my work pc, its fine, a little strange.
if this step failed, i think the best way is contact support or try in another pc. last night when it failed i try to flash via official method, shows cust update failed the reboot. i guess the sim not working is related to that.
when this step finished, the phone will reboot automatically.
Hi, I don't think that flashing that would help, can you acces the fastboot mode ? (vol down and power)
Cordially,

Need Help Installing TWRP

I would like to install LineageOS 14.1 on my S4 but I can't get TWRP to install. I'm running the new VRSGPL1 build and have it rooted. Also tried to install TRWP on rooted OF1 but couldn't make it work. I started with a completely reset and wiped phone each time. I used Wondershare to root, unlock the bootloader, and install SuperSU. I then try to use the official TWRP app to install. It says it succeeded but after reboot, I get the message that the phone didn't start correctly and that i need to use the Verizon tool to repair. I've tried MANY different methods to make it work so i'm at the end of my rope. I'm hoping one of you Gurus out there can help. Thanks.

You can only use Flashfire (v.53 or lower with this device) with a locked bootloader. You can't install TWRP or any other custom recovery. Don't keep trying because you will brick your phone.
PS- Wondershare nor any other tool (available now at least) will unlock your bootloader on this device.

No that means you're rooted
Ok. Thanks for clearing that up for me. I installed Flashfire. I tried v .52 first and it wouldn't start up so i uninstalled and installed v .53. It starts up and lets me choose my zip files to flash. I click on flash and it starts the process giving me the screen loading files then goes blank. I've tried changing different settings but i still get the blank screen. Any ideas?
