[Q] downgrading to v10k - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

When i tried to downgrade my L7 from CM10 to stock V10k it shows that the DEVICE WAS NOT FOUND? what should i do? Please help..

Maybe try reinstall kdz flash tool and drivers. Open kdz by administrator. Connect phone via cable usb without battery and pressing volume + and power. 3GQCT and cs emergency mode. Launch new software.

How do you use emergency mode in kdz flasher? What is the kdz flasher? And, how do you flash firmware with fastboot, flash recovery restore v20d from recovery backup?

all the answers are there
IT'S A KERNEL ERROR
1. Have the necessary software.
- Phone Drivers
- KDZ_FW
- The Room you want to install, in my case I served in the final Android 2.1, I suppose due to the use Android 2.2 I had made a partition so I'm not allowed to return to that version of Android.
2. When we light up the phone and leave us this error screen, press the power key + the Volume Down key to set the phone into download mode or (Download Mode).
3. Disable USB LG Driver Model, this will change depending on the operating system we have in the case of windows will be in Manage> Device Manager> Modems> LG USB Drive Model -> Right Click "Disable "
4. Open KDZ_FW select type 3GQCT, Phone Mode: DIAG, consider the room to install (File *. kdz).
Cannot flash any rom on my phone
Hey there, sorry if im spamming or doing any newbie thing, i've always try to stop that.
Recently i've try to get a rom on my phone but I've just got the kernel panic (blue error handler arm11 is crashed!!) I've had that before and solved it with no problems, but this time my computers or my brother's computer do not recognize the phone, not even after disabling the modem, and just when trying to flash a KDZ, this is what i get
[R&D Test Tools Log File]
02:56:37 : Launching SW update
02:56:37 : Unpacking KDZ
02:56:47 : KDZ file extraced
02:56:53 : Files were extracted.
02:56:53 : LGMobileDL Load.
02:56:53 : Port = -1
02:56:53 : Connecting to phone
02:56:54 : PHONE WAS NOT FOUND!
02:56:56 : ===FINISHED===
I don't know what can I do, tried with 2 computers, CS_emergency mode, 3 diferents rom, disabling the modem, but nothing! Even not in download mode.... Any suggestion?
As I said b4, sorry 4 spamming and 4 my english
if this happens (mine was bricked cant turn on no download mode no nothing) just send to lg get them to help you upgrade to 2.1 then try again
Is that the only thing left i could do? No way to try to fix it? I could send to the provider, but I don't know if there's a LG provider around, I may send it to "Movistar" (where i bought it)
---------- Post added at 10:03 AM ---------- Previous post was at 09:44 AM ----------
Whats just curious, is that my pc recognizes the phone, but the KDZ updater cannot! :/
like they say.
lg modem off in device manager.
switch-mode phone to downloding.
and try again. if youre phone die at 215, try with another soft
Or, delete ALL LG drivers, then restart ur PC, install them again, connect ur phone and flash in cs emergency... if doesn't, try another KDZ, or look for an out.kdz which could help, I've got about 7 arm crashed (kernel crash) and solved them that ways I just mentioned
Sent from my LG GT540 using XDA App
one trick about drivers is that you can try to connect it to the port you've never used before on your pc to connect your phone. It should then automaticly search and install drivers to recognize your phone
To all..
To fix this when I got this error you need to reflash a fastboot 2.1 and then go into fast boot and type the commands fastboot-w to wipe it then reboot into download mode and flash the normal stock rom
Same here :/ cant fix sending back to LG

Can you enter in download mode (Turn off the device, then press volume up and down, and while you are pressing them, connect the usb cable)?
Or can you enter in recovery mode?
If you can, in download mode flash a stock rom by lg flash tool, or in recovery flash a rom by otg cable...

Otg cable is useful if it lets you enter into recovery... If it does, do the following steps:
1- FROM PC:
Download the rom you wanna flash (for d800), better if it isn't heavy, maybe download one of the aosp rom (300 mb max);
When the download ends, take a usb pen, connect it into the pc, then move the rom in the usb.
2- FROM THE PHONE:
Enter recovery mode (search how on google, its really easy);
Once you're into recovery, connect the otg cable with the usb pen you used before;
If you are on TWRP, go to "mount", and select OTG, if you are on Philz's, ignore that;
Make a simple wipe (wipe to factory reset----> data, cache, dalvik);
Then, flash the rom you have in the usb pen by otg cable.
Ok, once the flash ends, BEFORE REBOOT, DISCONNECT THE USB OTG CABLE, then reboot...
Try this way, if it doesn't work, tell me

[Q] emergency mode in lg l3 (e400)

Hi Friends!
I have lg l3 e400. It was working well before i flashed a custom rom. But after installing rom it is showing emergency mode when i switch it on. Neither it is connecting to the computer nor reboots in recovery mode. It stucks on emergency mode. Is there any way to connect it to pc or get out from this problem?
Please help....
Connect USB cable and try to flash it via KDZ TOOL(is it detecting phone).
i had that problem too
what i did?
i connected the phone via usb, and selected emergency on kdz and flashed it, you have to install the lg drivers first

COOL1 BRICKED QUALCOMM HS-USB Diagnostic 900E

After using my cool1 for a month with no problems i decided to flash JUI 7.0.1 (with gapps etc...) on my Cool1 via TWRP but after doing it i realized it has many bugs and apps doesn't work properly. So i decided to return to EUI. After flashing the original stock firmware and rebooting the phone automatically switched off.
Power button not working, i cannot get into recovery and i tried all combinations of buttons without success.
When i connect it to the computer the red led start glowing and my computer recognizes it ONLY in Device Manager as QUALCOMM HS-USB Diagnostic 900E (COM3).
i have all the latest drivers installed.
i tried QFIL and it also recognizes it as QUALCOMM HS-USB Diagnostic 900E (COM3) and after setting everything when i click "Download" i get this error:
Start Download
COM Port number:3
Switch To EDL
Download Fail:Switch To EDL FailFailed to Switch to Emergency Download mode

to flash a new rom i need the phone to go into QUALCOMM HS-USB QDLOADER 9008 MODE but i tried everything installed the latest drivers even bought a 10$ EDL CABLE from amazon still not working always show me QUALCOMM HS-USB Diagnostic 900E
Any suggestion that would help, please... I think it's hard bricked because it cannot get into recovery nor the fastboot mode. completely dead only Red led glowing and QUALCOMM HS-USB Diagnostic 900E (COM3).
Thank you
hi
i installed custom recovery to cool 1 c 103
after it finished model number changed to 106
what i have to do?????
So nobody could help?
hello. probably you wipe system. .. or i dont know..but try this:
Forced writing a recovery mod using QFIL.exe:
a) open program qfil.exe
b) choose the recovery folder and xml file
(remember: for writing succes recovery you need type this command in cmd: BCDEDIT.EXE –SET TESTSIGNING OFF)
c) plug the phone
d) now. most important: Hold Volume up , Volume Down and Power Button At same time. and - always press the button
if not working : first d) and then c) steps.
if the qfil.exe read the phone hold continues button.
e) press download button on qfil.exe
Now in this moment you have a recovery mod.
This method it worked for me
So now you need a flash a rom.
I dont understand why after flash some room(miui 8, 9, etc) my phone did not open..
maybe some rom dont have a kernel
so.. i flash the jui 7 by cuoco and my phone its a live ()
now you can try flash now room (I'm not sure if it will work as I did not try)
1. wipe data and cache
2) flash new rom
edit: dont work flash any rom after flashed jiui..i dont know why......
Edit2: for change jui to eui watch this:
