Hi i have the ICS firmware installed and i think the option is somewhere else there

AP_CP_USB_Switching-> CP USB

though if i select it windows 7 finds a new device but no driver (have the LGmobile drivers installed and also flashed with smartool) and the pnp usb device found is looping after the CPU USB selection

the only time i see a modem being detected is @ the default AP USB mode [LGE Android Platform USB Modem]

but if i connected to that and try to type something into HyperTerminal i get a ERROR

my initial problem i get a red cross for the signal and the imei is empty, though what is strange i neither get any SIM message @ all if the SIM is inserted no pin question nothing :(
[LG Optimus Black] Orcusen:
You have the option to erase entire Flash cp marking and then restore imei

After, you can restore imei

After, you can restore imei

HELP! I flashed IZS via cwm, got bootloop. So I flashed tre v30b baseband with smartflash, but i'm not sure if I flashed it on the CP or AP D: the phone bootloops and when I get into S/W Update mode, the pc does not detect it. I've tried other cables and pcs, WHAT CAN I DO?
[LG Optimus Black] Orcusen:
Have a hardware problem. The USB connection on your phone is not good. You'll have to send it for service.
[LG Optimus Black] GPaul:
I heard about that...sometimes it works to flash p970 rom on KU5900 but you can loose your internal memory.:(

[LG Optimus Black] davifs:
you and I have the same problem ekkkke've tried everything, but my black optimus does not leave the screen lg.
[LG Optimus Black] Ekkkke:
Hi radkor,

I have one more question: The PPT in the Zip-File also shows some stuff on the first tab (Normal D/L) of the tool. Is there any chance to use these options and try another time? What about 'Erase entire AP' and 'Erise user data/AP'?

I have no idea what the first tap of the tool is about but it appeals me a bit to try some stuff... or does it not make any sense? Or makes it even worse?

THX

@davifs, if I find any help I will post it here. I will also send it back if nothing works and can tell what LG answers.
[LG Optimus Black] radkor:
I don't know. Never used this option...

"Erase entire CP" (on "ROM Copy D/L" tab, you can enable this option using Windows Enabler.exe), will overwrite FULL NAND overwriting IMEI part. This will change your IMEI.

You can revert it back to original imei using this:

1. Connect phone by USB
2. Enter 3845#*970# in dialer
3. Select Port Settings -> Select CP USB
4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200
5. Type AT if response is not OK, change port number
6. Type at%imei, it should display your current IMEI
7. 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
8. Reset

If you have nothing to loose you can give it a try.

I accidentaly checked this Erase entire CP option when I was writing this tutorial and successfully reverted my IMEI to it's original.

When I try to install the smart flash tool , i keep getting CRC error and cant install...
[LG Optimus Black] radkor:
You have bad download. Download it again directly from multiupload.

MD5 for SmartFlashTool_External.rar is f2def4fed0ae83854c9ddd100f2279ca

BTW. What are you trying to install? There's nothing to install. Just unpack/unrar it...
[LG Optimus Black] Tritio:
Hi all,

I tried to flash my black exactly like you said. The problem is when it was at 1:45.00 it was erasing something and then give an error.

The phone now is dead, I try to connect in SWupdate, but doesn't respond. neither LG logo is coming when I push the start button. I think it has no solution, but I have installed adb from sdk and I still trying to connect to something...

Maybe you could help me... any tips?
[LG Optimus Black] radkor:
Hmm, it looks like a hardware error (NAND write error) or problems with USB connection.

If phone doesn't boot into S/W Update mode I think that I can't help you... :(

Is it discovered by PC after USB connect or totally dead? Is battery charged?

What was going on with phone before you used SmartFlash?
[LG Optimus Black] Tritio:
Thanks for your quick answer.

i was updating the v20n yesterday via lg_update, and i get several times error communication, and retry.

This afternoon I thought to install via smartflash an original room, but easy rooteable, and I downloaded the bin of a v10a.

I started to flash according to this tutorial, and everything was fine until at this time, where it must be say download succesfull, says error.

After that, the phone still with screen SWupdate.

I close the window from smartflash, and I try again, but says that it's not connected.

In this moment, i choose to disconnect the usb cable from the phone. Went off, and never will start again.

The battery was full before to do something.

It isn't discovered by pc via usb, totally dead.

I was trying to connect via adb from android sdk, but says device nit connected, so I think, that I will send it to technical service to see what they say.

1. Unpack SmartFlashTool_External.rar with SmartFlash Tool.

wtf, how am i supposed to do this. I downloaded the file "SmartFlashTool_External.rar", but how can I unpack it with smartflash tool if the file was supposed to be smartflash tool ?

Should I install some other program for unpacking rar file ?
[LG Optimus Black] N1ldo:
Very good!

now just need to know how convert KDZ to BIN/FLS.
[LG Optimus Black] radkor:
Geeez. "Unpack SmartFlashTool_External.rar with SmartFlash Tool" means unpack ***.rar with SmartFlash Tool (in it) it means that in this rar is this tool...

I will change that as I can see it is not understandable for some people...

Where can I find a bin / sh pro v20 ROM LG Black Optimus?
[LG Optimus Black] radkor:
As I wrote HERE there's no V20 bin/fls yet.
[LG Optimus Black] :
Did anyone tried to use it under wine or virtualbox? I don't have any working winsh*t...
[LG Optimus Black] sp0rkticus:
Kinda of a n00b here, I was wondering if anybody knows which ROM should I pick for an LG P970h from Claro Puerto Rico. Not sure if picking the wrong ROM will mess anything up. Thank you in advanced
[LG Optimus Black] radkor:
You DEFINITELY need a ROM for P970H as ROM for P970 may brick your phone (I think that only radio would be broken, but better not to try).

Puerto Rico is MCC (Mobile Country Code) 330. Claro is MNC (Mobile Network Code) 110 so you need P970h 330-110 firmware.

Unfortunately there's such no that firmware available in bin/fls BUT you can flash LGP970hAT-00-V10a-CAO-XXX-MAY-23-2011+2.zip (or any other for P970H), then flash your original firmware by LG Mobile Support Tool (Mobile Updater).

LG Mobile Updater downloads ROM from the internet using your IMEI (not your current firmware) so it'll download correct version for your mobile.
[LG Optimus Black] radkor:
Links may not work. It's hard time for file sharing services due to Megaupload closing...

[LG Optimus Black] whatismyusername:
So I used this method to upgrade my phone to "LGP970_V30B_00" and had been using it for a few months.

Decided I wanted to install Clockwork Mod Recovery and tried to use ROM Manager to install it, but it bricked my phone and I get LG Security Error when I switch on my phone.

My question is, is there anyway to fix this without losing all of my user data like text messages etc.

[LG Optimus Black] Orcusen:
What version you have installed? ... v10, v20, v30

Please try a v10 or v20

Then you can follow the tutorial

Which Windows are you using?
[LG Optimus Black] Cru_N_cher:
v30 (ics release)

Windows 7 x64 ultimate

will try with the old v20 firmware and report back if it works there

Try another rom, i have the same problem, I bought mine on ebay and it is the same carrier 1&1, you have to use an older rom and then it'll get to do everything.

Search "BIN_LGP970AT-00-V10a-EEU-XXX-MAY-09-2011_0"

Hey, I am getting Sim security error on P970, so i thought i would give this tutorial a chance before going out and buying a new phone.

So far i have downloaded SFT rar file and v10 bin file in OP. The LG driver link dont work anymore tho. I havent anything else. I was trying to find v20 bin and fls files for my P970 on google but havent had any luck yet.

What is the difference between v10 and v20. also do i need to write down my imei numbers before diving into this?

V30C_00.kdz for LG P970

LGP970_CP.fls

i tried to use SFT and choose LGP970_AP[0].bin as AP and LGP970_CP.fls as CP

flashing went well but now P970 only showing LG when turned on

i'm trying to use LGP970_AP[1] and LGP970_CP now

hopefully it will be ok

did i do something wrong here?

[LG Optimus Black] Ereshkigal:
Actually, I did it with the update provided by LG, all went fine. It should work for you, too.

Do like I did. Write down your IMEI, use the custom firmware in the OP, and after you successfully reset your phone, use the LG updater to update your software (since you will input your IMEI, it should get the correct firmware for your carrier and region).

Mine worked like a charm. As for the driver, as I said above, you can download it through the official LG updater, too.

Hello Guys,

Im new here and i was able to install CM 10.1 (Dec-2012 release).

But my OB was running too slow and the GPS wasnt working so i decided to install the lastest CM nightly on it: cm-10.1-20130416-NIGHTLY-p970.zip

What i did:

- Just sent the .zip to my sdcard and did a install thru sdcard from recovery boot.

After this my clock isnt workin, my google play, my gmail, my data (3g) and also de wifi (so far that i was able to see).

I tried to install the gapps that i have on my sdcard as well: gapps-jb-20121011-signed.zip

But what i wanted was to zero my phone and do it from the begin,

tried to use the BFM with the 20a image (brazil one) but as soon as i selected the CP and AP source it biped.

Overall it didn't flashed :S

Now i trully don't know what to do, want the latest version but i was reading here and some of you guys were stating that the latest nightly CM wasnt working well so by saying this which one is the best for use, stable and working ok?

And how should i proceed by formating my sdcard, doing a factory reset, etc?

I appreciate in advance :)

[LG Optimus Black] CrawnberyJack:
for those who deleted user data via smartflash and than the phone didn't boot anymore , your motherboard is not broken. take the phone to a service and ask for "boot rewrite via jTAG" because you deleted the boot partition.

If the phone suddently doesn't open anymore after a rom flash , or anything like that , jTag might save you again.

It costs around ... 20 euro to repair the boot sector. Enjoy.
