Hi !

You confirm this flash method solves "Security Error" with non recognized sim ?

I have to flash a friend's phone, but don't have the phone yet. He just described error he had on the phone.

Thx
[LG Optimus Black] optimusBS:
some file image is incompatible for your phone look for another image file like v20h v10a etc

i use to have that same problem, you have to be in s/w mode so that COM will appear and not empty like that, just remove battery then keep holding +volume button then plug the usb to the phone.

[LG Optimus Black] jonas.h:
Hi guys,

a friend of mine has a huge problem with his rooted P970 (android 2.3): after installing an update, the system only boots into ClockworkMod, rebooting from there only goes into the CWM Recovery again. Even holding HOME+VOL-DOWN will also boot the CWM. Factory Reset and installing a ROM from CWM doesnt made a difference either.

So we tried to install a firmeware via SmartFlash (V20N). But the problem is that the COM-port only appears for few seconds until the CMW is completely booted, than it vanishes again. So we really have now idea what to do next.

Thanks for your help!
[LG Optimus Black] ramrod:
Hello.

did you read and understand the manual? do it again!

you have to hold vol + and then connect usb for the s/w update modus

if you follow the instructions, it works.
[LG Optimus Black] jonas.h:
We actually did this, but the port still disappears after CWM is fully booted... :( So it never went into the s/w update mode.

What does it mean? Can we flash something via CWM?
[LG Optimus Black] ramrod:
you must power off your phone.

Then vol+ and insert usb
[LG Optimus Black] jonas.h:
I know, we always removed the battery before each try... Didn't work!

Could it be, that the update destroyed the hboot and therefore it always directly boots into CWM?
[LG Optimus Black] RomWiz:
After s/w it boots into cwm for you to full wipe, flash su.zip and your rom.

[LG Optimus Black] mr.thing:
Hi All,

Have a dumb question about Smart Flash tool from LG. Yesterday my wife’s LG started to randomly rebooting (currently running Zeus 6.27n). Basically phone reboots, boots into lock screen and then reboots again, etc… I thought maybe to upgrade to latest Zeus, but when I tried to go to Recover Mode (CWM), phone just stuck on “LG” screen.

Long story short, because there was no important info on the phone I decided to completely “reflash” it with Smart Flash. I downloaded the tool and required patched Gingerbread ROM (patched_bin_lgp970_v20b_cis_mar_05_2012_by_snegovik) with BIN and FLS files inside it.

Installed LG Drivers, run the tool, set the phone to Software Update mode. Phone was detected successfully on COM8 port. I then selected required files and click “start”. Process took few minutes and was successful. Phone went to reboot and stuck on “LG” screen again.

I took the batter out, put it back in and powered the phone again. To my surprise there was still “Zeus” ROM animation logo and phone booted to “Zeus” lock screen. I was even able to unlock it and see that all my apps are still there and it is still “Zeus” ROM. Phone went to constant reboot after few seconds again.

I downloaded another ROM (BIN_LGP970AT-00-V10a-EEU-XXX-MAY-09-2011_0) and tried to flash it again. Process finished successfully but the result was the same (stuck on “LG” screen, take battery out, boot into “Zeus” again, then constant reboot).

Am I doing anything wrong? I thought with Smart Flash tool it will wipe out everything and make phone in “virgin” state. Could my issue be hardware related and I just need to throw this phone to the rubbish bin? 

Any help will be much appreciated.

Hello,

I have problem with ports, tried lg drivers 3.7.2 but theres still nothing to pick in com port combobox.

Running win 8 pro, maybe that's the problem?

Tried every usb port I have. Reinstall, restart..

This is what is says in device manager when I hold V+ and plug it in usb

sometimes 1st variant, sometimes other

Hello,

I'm on CM10 "stable" and I would like to upgrade the baseband version from V10E to V20S.

I succeed to convert the kdz in fls/bin file (with LG-P970 ROM COVERTER 2.1).

The fls file is the one for the baseband.

My problem:

Windows 7 only detects my P970 as storage device. It does not create the COM port in the device manager.

SFT can't see any COM port.

I have installed the LG driver (LGUnitedMobileDriver S4981MAN38AP22 ML WHQL Ver 3.8.1) but no COM port appears when I connect the phone.

Any idea?

Is there something to activate on CM10?
[LG Optimus Black] jdayscokn:
I believe it needs to be in software update mode for smart flash (volume + then plug usb) correct me if im wrong so you shouldnt need to do anything on the rom side
[LG Optimus Black] filzip:
I started the phone in "sofware update" mode but the COM port does not appear.

Can someone with CM10 confirm the phone is correctly detected by the LG driver and that the port COM is created?

I tried at home with Win7 and at my work with WinXP, but it does not work in both case. No port COM is created.

PS: if I remember well, the LG driver worked and detected the phone when I was with the stock ROM V10E.

I succeed to flash the baseband only

I finally succeed to flash the baseband only.

Actually the LG driver was well installed. There is nothing special to install it. Just press next, next, next ...

Here is the procedure I followed:

- install the LG united mobile driver

- remove the battery from phone

- start Smartflashtool

- press the VOL+ button and at the same plug the USB

- keep the VOL+ button pressed until the windows recognize the USB driver

At this time, FST will show you the COM port and the "LGE Mobile USB serial port" driver.

- switch to tab "ROM copy D/L"

- select the fls file in the CP bin field

- press start to begin the flash of the baseband

I failed in my previous tentative because:

- i thought I could flash it without switch off the phone

- the battery phone must be removed

- I did not keep the VOL+ pressed long enough

- the COM port only appears if you press the VOL+ button and connect the USB cable, and you keep the VOL+ button pressed until it is detected.

I hope this can help other.

I spent enough time to search

If you do have a recovery installed on your phone.

1- plug your USB cable on PC

2 - Remove the battery from your phone (remember without battery!)

3 - plug usb cable and wait screen change for a white battery icon.

4 - Press and hold: Vol down first and power button.

5 - hold buttons and wait to boot in recovery!

No COM port detection...

Hi,

I've read this entire thread, and saw only one relevant post to the problem I'm facing.

I understand I need to keep the VOL+ pressed until the computer detects and installs the driver.

However, After having it happen once, and possibly the cable lost connectivity during the driver installation, it just doesn't happen again.

I've tried three different computers, connected the phone with VOL+ pressed for long periods of time... dozens of times.

I just can't get the computer to detect the phone on S/W update mode, so I can't flash anything.

Has anybody had this happen? Know what I might be doing wrong?

Thanks in advance!

Tal.

yes you can use it for OB, it's recommanded to downgrade with SFT, security error is the message of locked bootloader ICS.

You can't install CWM in official ICS, bootloader is locked, but you can try some custom rom or repack in dev section.
