LG Mobile Drivers no longer connect

I am starting this thread separately from the locked on S/W and other threads because I have on possibly fatal issue.
I have had an increasingly hard time connecting my locked on S/W screen device to two different computers and having it recognized. I have reinstalled the drivers and constantly restarted the phone, but have reached a point where I just cannot get it connected anymore.
On this issue only - looking for suggestions.

When asking fof help with software you need to provide more detail, os... driver version... detailed error description... screen shots.
In addition its possible the cable itself is causing problems.

Have tried different cables - no effect. LG Mobile Driver versions tried were 2.2 3.01 and latest - 3.21. Have problems on 32 bit W7 AND XP machines.
No screen shots - was being shown in "My Computer' and connected OK initially - now not at all. I look at Device Manager and there are LG USB and other devices that show up - really has me stumped.

because you havent specified I'm going to assume you're trying to update using the kdz tool, can you post the log?
people have been most successful on XP, do your troubleshooting on that machine. Provide screenshots of the device manager and detail the state of your phone... which recovery you have and what you've done to it.

You want a log from kdz tool - will that show any specifics of the connection problem, or just show that it doesn't? I am back on stock recovery (but still rooted - difference of opinion as to if it matters). Also on stock ROM for the update.
I am trying to connect to the tool. I sometimes just try the LG Updater to see if it connects - no dice. When I was on CWM recovery, I could normally access the device and SD files - it is in the S/W updater mode that I am having all the issues.
At this point, the only reason I am trying to flash with the kdz tool is that it may be only path out of this mess. If I could somehow break out of the S/w Updater screen through another way - would gladly try it.

The kdz tool will work for this if drivers have been properly installed, unfortunately in your case there is a conflict and you haven't provided enough detail to get help....
Post the log and some screenshots of device manager so we can see what's going on.

Thanks for your offer to continue to look at this, but it has became too much of a pain and a replacement is due Monday.
The connection went steadily downhill after the S/W Update screen lock. Uninstalled and reinstalled a number of driver versions. If the problem is as I believe with the locked device, there would be no way to access anything.
NVFlash (without the battery in) connects OK, so I have used the one click root to format the internal card, factory wiped the rest (it has froyo on it), and stock recovery is back on. Could not get in to ADB anymore - so could not unroot.

[Q] PLEASE HELP with Faulty IFX Modem

Hi Everyone,
I've been given a friends phone to repair which he got with 'no emie' number showing, hence no signal. ClockwordMod recovery works fine and you can flash any custom 21e rom.
I've tried everything below on both an XP and Win 7 machine. All the procedures work fine on my P920 but fail on his. Both phones are running the same rom and kernel with 'Software Version: LGP920-V21e-Apr-19-2012' and 'Baseband version: L6260_MODEM_SIC_01.1042.00'.

[Method/Attempt: 1]
At first I assumed it was a simple case of restoring the imei number with 'tutty' using this guide:
[GUIDE] Unlock Phone / Recover IMEI
With my working P920 connected, when I switch the port settings to 'CP Image Download' the new driver is installed and everything in the terminal window works as it should:
When selecting 'CP Image Download' on the faulty P920, you get one beep where it disconnects and no new hardware is detected or drivers installed. All the connection the connections detected when it connected in developer mode are all gone from device manager. Hence, there are no working ports for Tutty to use. As expected, when trying to connect to a port detected in dev mode without switching the port settings to 'CP Image Download', tutty's blue terminal window either gives an error or doesn't respond to any keyboard input.
I next tried re-flashing a baseband in download mode using two different versions of SmartFlash. Both give a 'Timeout error' when trying to connect to the IFX Modem.
Mine flashed without any problems:
[Method: 2]
I next attempted to return to stock using the LG Flash Toolk files via The Dark Lestat's guide:
[GUIDES/TOOLS]Making Developing/Flashing/Returning to Stock Easier
The 1st attempt was with V21D_00.kdz but it kept hanging at Step : TYPE_WPARAM_IFX_DN_POS and failing at 30%.

For my next attempt, I tried these guides (without the modded USB cable):
[TUTORIAL] Flash BIN rom, Unbrick, Update - Optimus 3d (Service Flash software)

[GUIDE] [P920] [SU760] Resurrection Guide (Lets get those brick's fixed...)
and
http://forum.xda-developers.com/showpost.php?p=33509495&postcount=110
After several hours and many attempts! it can boot boot both into Normal Download mode and omapboot Download Mode (Button with yellow arrows followed by Korean letters). No matter which download mode I try, the LG Flash Tool gives an error after trying to communicate with the IFX Modem:
I have tried contacting others who have had similar issues but not had any replies.
Questions:
Would the modified USB cable help with the LG Flashing tool?
Assuming this is a hardware issue and only LG can repair it, is there any way of returning to stock V21E rom without root via clockworkmod recovery and then replace cwm recovery so there's no sign of it having been rooted?
I would appreciate any pointers or advice!

Try to flash prada baseband it is under IMEI tutorial with lg flash tool. Then see what is your IMEI an try insert old one with hyperterminal.
I woud first flash 21kdz and do factory reset so you know that AP part is ok. Then flash baseband only CP file.

Hi iodak, and thanks for the reply! If you're referring to the 'LGP940_CP.fls' baseband file, that was one of the first things I did (method 1 in OP). Just tried it again and getting the same error!
The IMEI is blank.
When the port setting 'CP Image Download' is selected, the connection to the phone is lost. The terminal window does not respond because the 'Intel USB Flash loader utility' is not detected, hence no driver and no port for it to communicate with the phone.

Also tried that (Method 2 in OP), keeps hanging when trying to communicate with the IFX Modem and fails shortly after.
Flashed several different kdz files on my own P920 without any probelms

Tried it with the 910K Ohm resistor between pins 4 and 5 of the USB cable but still the same.
Not had a chance to test the cable as I've lent out my multimeter to a friend.
Given it to a friend that has an Octopus box to try and repair the IMEI that way.

Hi, i have the exact same problem with my p920 and tried the same ways without success.
Could you solve the problem somehow? Octopus box?
Thanks, Krisz

Hi Krisztián, unfortunately the Octopus box didn't work. It failed to detect the phone in both 'Modem' or 'OMAP' modem. Also tried modifying the original LG USB cable with both a 910k resistor and a 56k resistor (as suggested by Furious Gold) without any luck. Hence pointing to a hardware fault!
The problem with the documented method of restoring the imei is that the corrupt/damaged ifx modem prevents the phone from going into 'CP Image Download' mode and thus allowing Windows to detect and install the 'Intel USB Flash Loader utility' so that Tutty can write/flash a new imei number to the modem.
As a work around you can try putting the phone into a mode whereby it iss ready to be flashed aka 'omapboot Download Mode' (Button with yellow arrows followed by Korean letters). Follow steps 2 to 9 in this guide by xbsall: http://forum.xda-developers.com/showthread.php?t=1942836
When you get to this screen:

Open Tutty (or hyper terminal) and select serial protocol. Click on open
Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
Type at%imei, it should display a dummy IMEI
Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK

If it works, try doing the "Extra Step for P920 User's" in xbsall's guide.
Hope that helps and let me know how you get one.

Hi Guan,
Thanks for the suggestion, but it did not work.
I can put the phone into download mode. (volume up +cable+power button), after that the computer recognize it correctly.
Com port is changed to 41, i connect with tutty to the com41 of the phone, but there is no response after.
I can not give any command, only the green cursor is there. (i tried to type and press enter even like this but no response.)
So what do you say? is this phone now equal to an ipod touch? only hardware fix can solve it?

Hi Krisztián, unfortunately the Octopus box didn't work. It failed to detect the phone in both 'Modem' or 'OMAP' modem. Also tried modifying the original LG USB cable with both a 910k resistor and a 56k resistor (as suggested by Furious Gold) without any luck. Hence pointing to a hardware fault!
The problem with the documented method of restoring the imei is that the corrupt/damaged ifx modem prevents the phone from going into 'CP Image Download' mode and thus allowing Windows to detect and install the 'Intel USB Flash Loader utility' so that Tutty can write/flash a new imei number to the modem.
As a work around you can try putting the phone into a mode whereby it iss ready to be flashed aka 'omapboot Download Mode' (Button with yellow arrows followed by Korean letters). Follow steps 2 to 9 in this guide by xbsall: http://forum.xda-developers.com/showthread.php?t=1942836
When you get to this screen:
Then:
If it works, try doing the "Extra Step for P920 User's" in xbsall's guide.
Hope that helps and let me know how you get one.

Hi n3fta, is there any signs of physical damage on yours? Also what ROM and baseband do you have installed?

There is no physical damage to the phone it looks brand new. The phone is on 20c just a stock gingerbread rom, I'm not sure about the baseband. I purchased this phone from ebay with missing IMEI after losing mine. I was aware of the restore IMEI thread so when I noticed this particular phone for $100 I thought it was a bargain and figured I could repair it in 10 minutes...I was wrong.
I've tried flashing the phone every way I know how and it hangs at waiting for IFX Modem no matter what I do. I'm really hoping this is just a software issue and there is no damaged hardware, but I'm beginning to have my doubts.
I decided to uninstall all drivers and now I cannot install the OMAP drivers. The phone will not go into download mode at all, nor does it vibrate like it should when going into download mode, I probably should have mentioned that the phone has not vibrated like it was going into download mode since I started messing with it. OMAP just keeps flashing over and over when I plug the device in with no battery, but does not appear once battery is inserted. I had no problem at all getting my old phone into download mode, so I suspect this has something to do with our problem.

Just noticed I can flash roms using CWM. I'm now on Thiaz but it has made no difference, is there anyway we can flash fls files using CWM? Not sure if it would help or not just throwing it out there.

Listen bro if map flashes its OK it happens to me and if it doesn't vibrate in download mode that's OK ...just install all the drivers again and restart your PC and the start again and flash a gb with LG flash tool..wish u the best and give feedback so we can help u.

Well I installed drivers again and it appears to be going into download mode and device manager shows LGE CDMA USB SERIAL PORT (COM41)
It still will not get past waiting for IFX Modem, even when trying to use the WKParks Omap for fastboot it doesn't ever get past waiting, every other program hangs at waiting for IFX Modem.

Try another PC with windows 7 and try another cable

I have tried using windows 7 and another cable but it's still not working.
My problem is the exact same as the OP of this thread. IFX Modem not responding and no new device being installed in tutty.

Still having this problem, anybody have any idea what the problem might be?
I cannot restore IMEI unless I can get a connection in putty but no new device is being installed when I dial 3845#*920# and select cp image download or cp usb. I have tried this on 3 different PC's XP, Win7 32 and Win7 64 the result is always the same...no new device installed.
When trying to restore using LG Mobile Software it always crashes at 15% during installation.
LG Flash Tool and Smart Flash both fail at waiting for IFX modem.
Using the KDZ installer it always errors out early in the installation process.
Is there any other way to restore my IMEI? Are there any alternate methods of communication with tutty or hyperterminal?
Would going back to Froyo possibly help? I would have tried it by now but can't find a zip version of the rom to install and the only way I can install roms is through CWM.
Any help would be greatly appreciated.

How to talk to the Modem with AT commands from the phone

I have noticed that when using a working Optimus 3d in device manager I see LG USB CDMA Serial Adapter or something to that effect, when using my non working phone I only get LG Mobile USB Serial Port. Without CDMA serial port I cannot update using Smart Flash, Flash Tool or LG Mobile Software Updaete.

I have exactly the same problem as n3fta...IFX modem not connecting...i did all the methods too..all the same errors.
The phone was working when i got it. I rooted it and installed clockworkmod but i was for p920, not for mine p920h. So when it rebooted it was in Lg logo loop. I used fastboot v0.5 to get it back alive and installed some ROMs but all with no IMEI or signal.
Is there a solution?

Is there a way we can get a full backup with someone that has the same phone working and load it on clockworkmod recovery? Or would it be like cloning the phone or something like this? Sorry, im a bit new on this area.

@berthilbl
I exhausted every software repair option before returning it to my friend, hence, it was definitely a hardware fault. Even Octopus box refused to detect the modem, even with the official LG flashing cable for the P920 (similar to the modded one in this thread but with a different ohm resistor). As it was on GB when I got it, the baseband had been flashed some time after it had shipped. Hence, it wasn't shipped with the fault as a bad batch but developed it later.
You mentioned that yours is a P920h flashed with cwm for the P920. Have you tried returning to stock recovery?
If all else fails, there are several video's on youtube showing how to dismantle the P920. It might be worth taking a look at the circuitry. May turn out to be something simple like a dry joint or just a loose connection.

[Q] Can anyone help me

Phone facts:
LG-F180, S/N: 0066451ae1d458e3
TWRP 2.5.0.0 installed together with LGNPST TeenyBin
From the fastboot screen
PRODUCT NAME mako
VARIANT mako 32GB
HW VERSION rev_11 (&¤)
BOOTLOADER VERSION MAKOZ10f
BASEBAND VERSION N/A
CARRIER INFO None
SERIAL NUMBER xxxxx
SIGNING production
SECURE BOOT Enabled
LOCK STATE UNLOCKED
NOTE: I found somewhere that rooting is NOT enough you also have to unlock, (FreeGee?). Could someone please confirm or reject?
3) Now I turned to “[REPAIR] TeenyBin - Softbrick Quick Fix / Bootloader Unlock [E971, E973, E975, F180*]” using LGNPST and TeenyBin. Finally something happened – I could access the TWRP built in.
4) Then I used ADB to push ROM to the internal SDCARD and recovery to install. But this method failed – tried several ROMs which all gave errors initially. I discovered that the install script pointed at “e975” in(ro.product.device and ro.build.product but the phone reports “geehrc4g”
This is the output in recovery.log when trying to flash ROM
Warning: No file_contexts
script aborted: assert failed: getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975"
assert failed: getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975"
Following the advice of changing the script by
a. Deleting the ‘assert’ line in the script, or
b. Changing the element to what the phone reports did not help
E:Zip signature verification failed: 1
Error flashing zip '/sdcard/thinkingbridge.zip'
Updating partition details...
To ensure working environment I tried to flash gapps which worked perfectly so connection and recovery must be functional.
5) Now turning to: ”[GUIDE] How to UNBRICK your Optimus G - security error, bootloop etc”
I used the method described and downloaded the appropriate KDZ file etc. etc but flashing gives this log:
10:05:58 : Launching SW update
10:05:58 : Unpacking KDZ

10:09:29 : ===FINISHED===
At the point where KDZ file is extracted the phone reverts from download mode to recovery which is probably why it fails.
I read the thread at xdadeveloper forum "[Q] Unbricking LG Optimus G e975 - using LGNPST, TWRP, ADB". Do all the things suugested but nothing happens.
I am so confused about somethings that are:
In recovery mode it shows that it it is a MAKO product. What is this mean because every thing i know is that it is a LG Optimus G F180 and after searching goole, i find that MAKO is a Nexus 4. So What ROM i have to download and from where?
How can i solve this problem? Please help me and reply me. I tried every method suggested on internet. Many people have same problem stated but no solution is given to them..
My email is [email protected].

Hi,
Yes, you have to unlock and root.
Locked phones are arrangements made between a network provider and a phone manufacturer. So your phone model is locked by your phone manufacturer and it is tied to a particular network provider.
The Nexus 4 (MAKO) and your phone has similar specs, except that Nexus 4 does not support microSD, so you will have to install it from the phone's internal memory (aka "sdcard"). Custom ROMs for phones with microSD are usually installed from the microSD instead of phone internal memory.
Hope this helps.

[Q] P500 - Emergency mode - KDZ and LGMDP errors

Hi everybody,
I’m at a point where I need to get some help…
My story:
I hard bricked my P500 one year ago … I had CM7 on it, and I installed CM10, but had no network,
so I upgraded the baseband, unfortunately it froze in the middle of the upgrade, I took the battery out, and it was the end …
BOUM … No fast boot, no emergency mode anymore … nothing … dead … Impossible to switch it on …
I bought a new one, which is working under CM7. No problem.
(So if it helps to fix the old hard bricked one I have a working P500 under CM7)
I just got the idea to fix the dead one! Because it’s fun, but I’m stuck and need some help.
JTAG reset:
Since it was hard bricked, the only possibility was a JTag reset. I found a nice guy doing it close to my place and it worked!
The phone has been recognized without any problem, the full dump worked without any mistakes, and finally the bootloader has been restored with a RiffBox.
(See attached picture) The phone can now reach the emergency mode again.
Flash original firmware on P500 with KDZ - not successful:
http://forum.xda-developers.com/showthread.php?t=875881
The drivers from LG are installed, I disabled the LG modems,
my computers (xp) sees the phone without any problems.
I tried to flash the original firmware on it with KDZ, which I’m used to do
but this time I get every time an error
"Error upgrade
WPARAM : 100
LPARAM : 4008"
(Logfile attached)
Flash stock rom with LGMDP – not successful:
http://forum.xda-developers.com/showthread.php?t=1324105
Same here, the P500 is recognized by LGMDP,
it seems the IMEI number is not active,
and everytime I flashed a rom, I got an error:
“Error! AMSS writing” (See attached picture)
Flash a custom recovery (CWM) from LGMDP – not successful
http://forum.xda-developers.com/showthread.php?t=1318750
I also tried to flash CWM, LGMDP seems to have installed it, I got a “Download complete” message,
but I cant access the recovery mode. Vol Down +Home + Power On just brings me back to the yellow emergency screen.
I of course checked everywhere online … I have seen sometimes the same errors as mine but no solutions ….
Do, one of you, have a solution? Or know the errors I’m encountering?
Or do you have another way tp get out of the emergency mode?
Thank you for reading and helping me in any way …
Bestrau.

How much did JTAG cost ?

Make sure you have the correct KDZ file for your device and download my attachment.
I know for a fact that this KDZ Updater works as it is the exact one I used to restore 2 P506's back to life just a month or so ago. I did this on Windows 7 Professional 64 bit so it should also work for Windows XP.
Do all the usual KDZ stuff. Disable LG Modem in Device Manager, etc. Then follow the directions in the ReadMe.txt in the attached archive. Best of luck!

Look man, it's upsetting to have the phone in Emergency Mode. August last year, my phone got stuck too, tried every program I could and never boot successfully. Took my phone to the store, they said they tried everything but they couldn't make it work. After a couple months with another device I decided to plug my LG P500 in to the computer and see if there was any new program available to flash. Strangely, my phone BOOTED in the stock rom and has been working flawlessly since. What I'm saying is, don't lose hope, this phone is amazing!
