i have my KS20 from Hong Kong and it was a chinese rom.

that means mine should be an unbranded one.

i tried so many times to flash with an english rom but it never works.

at the end, i can manage to flash with the chinese 10b and working good.

with the english rom of 10a or 10f or 10a+10f, all were saying "sim card locked" and OPT blocked after i restored my NV file.

please advice how i can flash with any english rom and which one should i use?

is there any steps i have missed out? do i need LG.exe?
[Upgrading, Modifying and Unlocking] jfive:
im just a newie myself but yes you need lg_.exe to get your code from the phone. this will sim unlock your phone. but if ya not sure wait for an expert to answer (grin) :D
[Upgrading, Modifying and Unlocking] raykisi:
Hi, stephen.chan

Branded KS20 = Sim Locked KS20 which is locked to a specific network so you can't use other service provider, if you want to change service provider then you have to unlock to make it work.

Unbranded KS20 = no sim lock KS20, can change service provider as you want.

I think your KS20 is Unbranded, try flash the Official English HK_10a again with the "Erase EFS" option checked. If still can't solve your problem, pls tell the exact problem after (whether it is "sim card locked" or "OPT blocked") these steps

Hi, 42NeR

Beside it shows "no phone" and "none", is the com port shows "enable"?
[Upgrading, Modifying and Unlocking] stephen.chan:
i am now sure i have an unbranded KS20 (tried with the sim card of other network and it works)

also tried to flash the Official English HK_10a again with the "Erase EFS" option checked in Emergence mode.

it runs perfect before i restore my NV. after the NV restored, on the today page, first will appear "sim lock" then after few second, "OPT block"

please advice.
[Upgrading, Modifying and Unlocking] 42NeR:
raykisi

Yes, com port it shows "Enable" and shows the port number, No phone, None. If I try backup NV via such comport:

1. A computer shows IMEI and Bluetoth address NOT_ACTIVE.

2. After I press the button "NV backup!" in few seconds it shows "Error! Can'nt connect serial port! Please restart and reconnect device." And after that a computer shows com port "Disable" and in a folder with program there is a folder NV_BACKUP with a file xxxxxxx.nv2 with size 333 bytes. After plugging-off usb cable from a computer then plugging-in to a computer it shows again com port "Enable", but of course "No Phone" and model "None".

I think problem is with device. I can't find windiag.dll in \WINDOWS.

Could You chek hiden files and files in ROM on your device and find this file? I think this file is there only on LG device and works like a driver for mounting com port inside the device for transfering information from the phone part to a computer. May be my problem is in this file.
[Upgrading, Modifying and Unlocking] dorik2k:
If after restoring NV you get OTP Block, than you should have a branded phone. It can connect with other sim cards just because it is unlocked... Try the hybrid rom... maybe it could work...
[Upgrading, Modifying and Unlocking] edwinlcw:
Hi all, i believed i got a unbranded ks20 in Malaysia, so if i flash the official HK rom v10a, do i need to backup the nv file or the program will automatic backup for me?

thanks
[Upgrading, Modifying and Unlocking] stephen.chan:
i have also tried with the hybrid rom, but also same happened, OPT block as well as SIM lock

what should i do if i want an english rom???
[Upgrading, Modifying and Unlocking] dorik2k:
Try flashing a branded rom, choose one randomly, or at least with a language you can understand some words... and if that works, try to backup the nv2 file of that rom, and flash again the english hybrid rom... maybe this can help...
[Upgrading, Modifying and Unlocking] stephen.chan:
thank you very much for your idea...

but... which is a branded rom (i am so sorry but i am REALLY confuse with those branded or unbranded roms....), please advice for a German one with thanks.
[Upgrading, Modifying and Unlocking] mladenst:
Hi there! I'm new here so I have few questions. Does this new English HK 10a fixes issue with Direct draw so IGO and other applications can work? Anyway I was trying to flash this new ROM and did everything like described at first post in this topic, I did hard reset too before all of this, but at the point after I browse to image folder and then click START, and then YES in next confirmation dialog I get message: Error! Security mode. What I'm doing wrong here? In that window it shows just model: KS20, and compiled/released date, IMEI, Bluetooth address, cal date, current address it's all blank/empty. Thanks in advance!!! I forgot to tell that current ROM version on my phone is V10b, as well as bootloader and modem firmware and ROM date is 2008-3-7 if this can help somehow!

I have do the changing in engeneearing menu and after e soft reset i have installed the lg corona than the new modem was installed correctly to may laptop but when i imposted the remote connection vodafone the laptom reply to me with this message errore "the modem cannot respond" why for you?

In second i would ask you more help to procedure to flash new rom on my ks20. I have made the backup with lgmdp euro correctly and the sire is 116kb.

But at this point i dont know how to continue. The flash.bin that i have downloaded is already that of the english because i have found only one of this flash.bin and i presumed that is of the english rom. Do you confirm?

After i have made the backup how to i continue?

And afeter the flash what i have to do over the restore nv2?

Please halp me in italian language so I am not wrong.

Thanks so much for your gentleness and im sorry for all these questions.
[Upgrading, Modifying and Unlocking] stephen.chan:
tried to do it but i did not even have the chance to restore the NV (OPT block after the first restart, on the green window page)

I did it with normal mode by the way, is that normal?
[Upgrading, Modifying and Unlocking] MarcosC:
I had exactly the same problem, you have to change your registry and/or try in a different computer (I had to do both). Search this thread and you'll find the answer.

[Upgrading, Modifying and Unlocking] stephen.chan:
dear all,

i have finally done it with version 10a. i am not sure if it has anything to do with my 10e GER rom (did not even able to get to "today") or may be i did it wrong the first time...

anyway, i have flashed the 10a rom from normal mode of 10b rom (but not yet restored nv file).

it works perfect but "no phone". then i used the method of "clear all" and NV dauft to restore my old nv file (it was made from 10b) and it is done!!

thanks so much to dorik2k and Rayskis, you guys are excellent! thank you!!!
[Upgrading, Modifying and Unlocking] dorik2k:
When flashing, you have to choose Erase EFS option,,, as this will prevent conflict with old configurations,,, It's a select box on the lowerleft corner of the flashing window....

Anyway, you have to flesh in emergency mode now, as you cannot switch on the phone... Hope you have the NV2 backup...
[Upgrading, Modifying and Unlocking] arash3210:
thank you dorik2k for helping us to solving problem;)!
[Upgrading, Modifying and Unlocking] stephen.chan:
i have done "erease EFS" everytime, also but still did not able to get it done before.

as i said before, i am now 10a english rom working really nice, but still do not know how i have done it.

coz the 10e GER never works on my ks20 before too.

anyway, still want to thank you very much.

Hi dorik, excuse me for the trouble. have sent you a mail some days ago but I have not received an answer. I have perhaps bored you, I am sorry it.
[Upgrading, Modifying and Unlocking] 42NeR:
My experience of LG KS20 following:

1. There are some ROM's that can't backup .nv2. Those ROM's do'nt contain first of all the file windiag.dll in \WINDOWS directory on a device. But a copying this file in directory is'nt enough. LGMDP shows anyway "No Phone". It was such ROM:

WM 6.0 - 5.2.1626

ROM Version v10b_B_3.1.1.00215J

Bootloader version v10b

Modem version KS20-MSM7200-V10b-FEB-14-2008

Factory version

KS20-00-V10b-CIS-XX-FEB-14-2008.

After reflashing my device with ROM HK English v10a everything with connection to LGMDP is OK

2. What described at the link

(how to change IMEI and bluetooth address)

http://xdaforums.com/showpost.php?p=2354610&postcount=362

is mostly false. IMEI is READ_ONLY_S and you can't write IMEI directly. But it's possible to change IMEI if Yo will be follow next instructions;

1.You should have installed on PC QPST and NV Editor.

2. Connect NV Editor via QPST port to a device, read all of nv from mobile, than save it to a file .brt

3.Flash new ROM without restoring .nv2 with option "Erase EFS" enabled.

4. Open in NV Editor the saved .brt file and press Find, enter 550. It wil be IMEI, edit it in the right lower corner of window. You should edit the column Hex Value (IMEI is writted in little indian (from right to left) after the letter A.)

and then connect to the device and after a changing IMEI press download all actieve to mobile.

5.Soft reset device, connect LGDDP and restore .nv2 with the option "Reset darabase&contens" (NOT ERASE EFS!). Iou'll have new IMEI.

To change bluetooth address with this version of NV Editor is'nt possible.

[Upgrading, Modifying and Unlocking] donnaw:
I am new to this forum and can say that I have read all your posts with great interest (even though they are all WAY over my head). I have a couple of questions.

I just got my KS20 about a week and half ago. I purchased it as an inlocked phone and it was shipped from Hong Kong. I have T-Mobile USA as my carrier. I love the phone and it works as expected except for 2 areas:

1) I have been on the phone with T-Mobile for hours trying to configure it for internet with no luck. We have tried every configuration possible (except the correct one??). Initially all I got was

"“Dialed wap.voicestream.com

Cannot connect for an unknown reason. To check your connection settings and change them if needed tap settings. If the problem continues, reset your mobile device according to your manufacturers’ documentation and try again.”

I have finally gotten rid of that and have now been able to connect to their Edge network but still cannot get a browser to open a url (I have the $5.99 plan). Nor send MMS.

I do find that there are several profiles for Asian carriers under the AutoProfile selections. Is it possible that either this was originally a branded phone and was unlocked by a third party or that LG missed something when they created an "unbranded ROM? Could there be a registry key value that makes the phone still think it is on another carrier?

2) The phone is supposed to have Bluetooth 2.0 with A2DP. checking my version I.8.7 build 0900. would some of you please check your phones and let me know if you have v2.0?

any help anyone can give me would be greatly appreciated. And if my questions sound dumb I apologize. I'm just a little old lady from Texas and not too well versed in cell phone ins and outs.

tryed the whole night with no luck .

every time i had a time out when i back up the nv2 file

the last what i did is

1 power off the phone

2 disconnect the usb cable from the phone

3 hold down the send, internet button and pressed the power button

saw a green light coming up ( emergency mode)

4 connect the usb cable and opend lgmdp_euro

and now it is flashing in emergency mode with succes

my lg ks20 is branded with vodafoon with no simlock i think. it sees my t-mobile simcard
[Upgrading, Modifying and Unlocking] raykisi:
OMG....

To backup .nv2 file, u should backup b4 flashing, but not backup after flashing

So the step is:

1. Backup .nv2 file

2. Flash your phone with other rom in normal or emergency mode (normal mode prefer)

3. Restore .nv2 file automatically by LGMDP or manually by choosing ur .nv2 in LGMDP and restore it back to KS20

If you hv any problem about flashing and connecting with LGMDP pls consult my posts, you can find them in my signature

Also, since it sounds like you have flashed your phone without making a .nv2 backup 1st, so you probably has lost your .nv2 file ady and forever, your phone should work like pure pda with no phone functionality now.

Am i rite? Congulation for that!!! this is all due to you flash your phone without read through all information (especially in my posts)

But if you do read in the future, you may be able to find a solution.

Good Luck

been trying to get activesync working with this phone the whole afternoon with no luck, 5 minutes ago i did a factory reset and it worked

then i saw your unlock the lg ks20 topic cause my phone was locked again, downloaded the files , started it and now its working :) still without the back up , coulndt get that working
[Upgrading, Modifying and Unlocking] raykisi:
activesync work only with "Microsoft USBfn" setting in engineering menu (which is default setting)

But LGMPD only work with "LG composite" setting in engineering menu

So you should set the relevant setting for different purpose

You can't backup .nv2 is because either you are too stupid or you computer not working or cable broken.

I think is the 1st reason

Steps:

1. Install "LG Corona USB Driver"

2. Change necessary settings in engineering menu

3. Install "WinDiag_Open.cab"

4. Soft reset your phone

5. Connect your phone to LGMDP
[Upgrading, Modifying and Unlocking] nnndoh:

and i know that if i need the backup file, you can make me one via the imei number. but it seems that i don;t need that

KS20 won´t turn on

Hey guys,

Sorry for spamming with noob problems, but i read through these forums for several days - and I truly admire the work of some of you guys - before laying my hands on my new phone, and i still messed something up and can´t find any answer to my problem...

I followed the instructions to load the unbranded HK rom (the phone is unbranded), everything went well, LGMDP said download was succesful, the phone turned on, I got otp block...

I wanted to get it to emergency mode (send+browser buttons), so i took out the battery, plugged back the usb cable, inserted the battery again, and tried to enter the emergency mode. It didn´t work, so i removed the battery, tried again, removed the cable.. and so on.. and while at the beginning it showed some signs of life (green led, display saying battery is charged), now it doesn´t react at all. It´s just dead, whatever I do to it...

Any ideas..? Thanks a lot!

[edit] now it worked without the cable plugged in.. (??) but I still can't get to emergency mode :(
[Upgrading, Modifying and Unlocking] raykisi:
Visit my post pls

http://xdaforums.com/showthread.php?t=405945

For OTP block result after flashing, there are two reasons:

1. You didn't check the "Erase EFS" option for flashing

2. Unbranded phone flashed with Branded or Hybrid rom, OR Branded phone flashed with Unbranded rom

So, in order to eliminate the occurrence of Reason 1., you must flash with "Erase EFS" option, if there after still coz you OTP Block or illegal use then it would be due to Reason 2, try flash with another rom

For emergency mode, you hv to turn on emergency mode b4 connecting to USB and connect to USB after, if you connect USB 1st then press the 3 button to emergency you ll never get there
[Upgrading, Modifying and Unlocking] Chartres:
Thanks a lot raykisi!!!

It was Reason 1 and I plugged the usb cable before trying to get to emergency mode (i followed the official LG service manual).

Where do I donate?? :)
[Upgrading, Modifying and Unlocking] robotov:
A stupid question

Sorry guys, I just want to ask you:

When you flash your LG using the LGMDP utility with the HK English ROM, for example, does this procedure change the IMEI of your phone? I hope, it doesn't.
[Upgrading, Modifying and Unlocking] Chartres:
Hi Robotov, no, if you backup your nv2 file beforehand (in LGMDP, Tools > Backup nv2) and then restore it after flashing, your IMEI will not change. If you fail to do that, the flashing will erase the IMEI and you won´t be able to use your phone - unless you manage to do some magic using some instructions here: http://xdaforums.com/showthread.php?p=2248729.
[Upgrading, Modifying and Unlocking] raykisi:
Chartres is right, ppl who lost their imei no. after flashing was because they lost their .nv2 data in the phone which contain their KS20's imei no and also the calibration data for the phone functionality.

So, before any flash job MUST backup your own .nv2 file first. Although i can get you a .nv2 file, it won't be prefect, it will be branded and the last digit would likely to be different
[Upgrading, Modifying and Unlocking] robotov:
Thank you, guys!

I definately have my backup (the .nv2 file). I asked my question for another reason. Let's say I've flashed a new ROM. The procedure went fine and the phone started working properly. However, after the flashing, I can suddenly have another IMEI number which belongs to a stolen phone, for example. In this case I can have legal problems with my Operator - right?

Thanks!
[Upgrading, Modifying and Unlocking] raykisi:
I would say this is impossible, unless you phone is 2nd hand and the pervious ower lost his .nv2 and flash a .nv2 file which get from another KS20 and sold it to you, or you got another .nv2 file in the LGMDP.exe folder and it automatically restore it to your phone after flashing.

BTW is you new IMEI no. starting from 357323-01-XXXXXX?
[Upgrading, Modifying and Unlocking] robotov:
Exactly

357323-01-XXXXXX, you are absolutely correct. Thanks!

No Phone

Hi, How are you all? I'm new here and have been following this thread. I got through many of the instructions and have flashed my KS20 unbranded from Chinese Rom to English Rom. The only problem I have now is my KS20 is only a PDA and no phone function. I tried checking the IMEI and it was a strange numbers with 0000023000000<0. I guess somewhere along the process, I must of did something wrong. I tried to load the nv2 files and still no phone. I used QPST to edit the IMEI but couldn't edit the last digit. The phone now has 357323-01-xxxxxx-0. My IMEI is 357323-01-xxxxxx-1.

Since my IMEI is wrong, is this the reason why I have NO PHONE?

Is there anything else I missed?

Please help. I would really appreciated.
