[LG KS20] "Unavailable OTP Block" solution

[cleverguy]

Hello everybody! :-)

I have read lost of post regaring KS20 flashing procedure.
Most common is to:
1) backup NV2 with LGMDP
2) flash phone with desired ROM erasing EFS
3) restore NV2 settings

The only problem is that after restoring NV2 the phone says "Illegal use" and "Unavailable OTP Block" message appears on the screen, so the phone becomes unusable... :-(

We all should backup NV2 with QPST Service Programming instead of LGMDP.

However if you have a NV2 backup done with LGMDP only there is a solution :-)

1) Flash with any ROM that does not cause "Unavailable OTP Block" error erasing EFS
2) Restore NV2 with LGMDP, but do not restart the phone!
3) Backup NV2 with QPST Service Programming to QCN file
4) Flash with the ROM of your choice erasing EFS
7) Restore NV2 with QPST Service Programming from QCN file

And that is all! :-)

Of course you have to switch USB settings with Engineering Menu after every flashing.

but i am now not able to connect with the computer,

what can i do?

[cleverguy]

In that case you should use Emergency Mode :-)

Turn on device while pressing Send and Internet buttons.
A green LED will light.

[stephen.chan]

yes it is done.

i found out i can only flash with chinese rom, but i really want an english one.
(my ks is bought in hk with chinese version)

can you advice me how to flash with english rom?

[cleverguy]

Well, you should be able to flash ANY ROM using one of those flash tools mentioned above.
I had Polish unbranded ROM and I checked several branded ROM-s like French, German, Polish and finally English (HKE).
If you are able to turn on your phone in emergency mode you should be able to flash it, and it does not metter what ROM do you use. The problem might be in ROM format. Do you have a standalone MZ file or flash.bin with additional files?

[bradbox]

Try the branded ROM and pray.

[kelmen]

When i turn on device while pressing Send and Internet buttons.
it didn't show a green LED light and didn't go to emergency Mode!
what should i do?? help...

[raykisi]

1. Disconnect from USB
2. Press Send and Internet buttons and hold
3. Press Power On while you r still holding Send and Internet buttons
4. Then u should see a green led on, and ady to connect USB

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

Hi Ray, the second you said caused my problem.
My phone is SFR French.
After read your post I have to raise a question: if I still want to flash a unbranded rom, how to solve the "unavailable otp block"? Do you have any advise? Thanks!

[raykisi]

SFR French = Branded KS20

I think i have stated very clear in my post with the title "[How To] Flash Unbranded rom in Branded KS20"
Dun tell me you can't understand, unless you can't read english.

If you understand the steps and the rom that you need go ahead n do it, if you still hv no idea after reading my post, then i would say you r too smart to do the flash, i recommend you to stay with french.

Good Luck

Thank you ray, I have found the solution.:)

Hi guys :)

I own a greek Vodafone KS20. I bought it in Greece. I live currently in Sweden. The phone at some point had a problem with the touch screen and i sent it though UPS to Greece to be fixed by LG. The phone was working otherwise, appart from the touch screen. They claimed they fixed it, so i paid for the UPS to bring it back (80E all together). I received it today and the phone gives back the anavailable OTP block error while opening. LG Greece claims that they did nothing to the software.

So basically my question is if there is there any other reason that this error would occur besides a bad flashing procedure? They are not paying for the device to be delivered to them and i am not paying another 80E to do it again either.

And the second question, since my line of work is not with computers, is whether there is a kind soul here that would teach an old dog how to fix this step by step? Before Raykisi or abybody else jumps on my back ( :) ), let me say that I did read this (http://forum.xda-developers.com/showthread.php?t=405945) and this (http://forum.xda-developers.com/showthread.php?t=369481) but still i am not really sure how to take the first step. I can not get into the device so i cannot press anything on the dialpad.


If i get it right, the process would be to:

- Extract the current Rom or whatever.
- Patch it somehow
- Get it back in?

Is there anyway that i just overwrite it with a new one and be done since I dont wont to unlock the device, not to use an unbranded Rom, just to make it work again.

Thank you in advance for your help and understanding.

Easy problem, but y nobody trying to ask question in my own post?
Here is my own post:
http://forum.xda-developers.com/showthread.php?t=405945

Steps:
1. Find out your phone is Branded or Unbranded, the definition of that is in my post
2. Choose the right rom, Branded phone Branded rom, Unbranded phone Unbranded rom, for english there is not Branded rom so you need hybrid rom for Branded KS20, in my post you can find "English-HK-10a + French-voda-10f Rom", also if you are not after it, there is also a list of official Branded or Unbranded roms
3. Since your phone is hving "OPT problem", you can only flash your phone in emergency mode
Emergency mode: make sure usb is unpluged, turn off device, press and hold "send" and "browser" buttons then press power on, a green led should be turn on, connect it to LGMDP and flash it with the rom you get in step 2
Note: since you flash in Emergency mode your original .nv2 data in KS20 will be lost, if you did make a backup of it b4, restore it back to the phone after flashing, if you dun hv a .nv2 backup read my post at the very top you will find out how to get 1 from me
Also, to connect LGMDP to restore .nv2 file after flashing you ll hv to read this:
http://forum.xda-developers.com/showthread.php?t=396032

BTW, since you will lose your original .nv2 data (my .nv2 solution is not perfect) if you never make a backup b4, i would prefer you send it back to LG

Good luck

raykisi thank you very much for your help :)
If you feel this should be in your own thread then i can continue there.

1. It is a vodafone mobile, it has the logo, so it is branded.

2. So since it is a greek vodafone mobile i guess that this rom is the correct one????

Greece Vodafone 10g (DZ-KS20-00-V10g-202-05-APR-2-2008+0.dz)

I found it in your thread. Can i flash directly with this Rom?

3. To flash it I need the LGMDP program as you said. I downloaded it and the folder has 4 different versions: Euro, H3G, Open and US. I guess i should use Euro???

4. Will the LGMD recognise by the LGMDP program when i connect it to the USB in emergency mode? How will i know if it is recognised?

5. Are there any special settings in the LGMDP program that i have to select before flashing?

6. If i understand correctly after flashing in emergency mode it is certain that i will lose the nv2 information. I dont have a backup since i was not responsible for this error. I can send you the IMEI so that you send me an nv2 file for my phone. Does this nv2 file work for sure in branded phones? Because you said in the first post that the last digit is always different. What is the possibility it doesnt work from your experience? If it is very low maybe i can take the chance but if not, as you said maybe it is safer to pay another 100E and get it back to LG.

Thanx again for your help :)


Edit: Not to get me wrong, i understand that there is no responsibility whatsoever by you guys here, whatever i do, i do it myself. I am just trying to understand what are my chances of fixing this darn thing myself.

[raykisi]

1. correct
2. correct, but you also can flash to any other language as long as they are Branded rom, or make a hybrid rom
3. I only used Euro b4, hvn't try other version
4 As long as you switch your phone to emergency and connect to USB, LGMDP will recognise it,
but for normal mode which you will use after flashing to restore .nv2 file you hv to follow this post: http://forum.xda-developers.com/showthread.php?t=396032
To restore .nv2 manually by LGMDP Read this (from post #104 to #118):http://forum.xda-developers.com/showthread.php?p=2531611#post2531611
5. Just try to play around with LGMDP, it is not complex, the only tricky thing is, you can press "Original" or "DZ" buttons to switch between two flashing mode
6. with my Branded .nv2 file, you can use with any branded rom, if you want a perfect imei no. you hv to go for LG, if you dun mind the last digit would be different then go for me

Your .nv2 file is ready to pick up, but you didn't send me your email address

If you need further help pls post in my post pls

did you backup your own branded nv2 file with LG MDP?
If yes, you can reflash the unbranded rom with two mbn files "amss..." and the "partition" mbn file replaced by the three of your branded rom, and then restore your nv2 file, the problem will be solved and your own imei can be back again.

[vduenas]

Cleverguy,
I have tried what you said, but when I'm doing the Nv Restoring, my phone restart by itself, and shows OPT Block, I dont know what to do.
My celphone was unblock, I have tried with 3 ROM, but the phone doesn't recognize my SIM.

thanx

By this methond I recorvered IMEI, but I can't calling - there is no service :/ I dicovered that last digit of my phone IMEI is different - it's "0" and should be "1" (The last digit of IMEI is check digit). Maybe this is the reason? It's look like the IMEI it's not correct - when I checked on site http://www.numberingplans.com/?page=analysis&sub=imeinr the number which is edned at 0 - the "analyse" submit "Please check the IMEI number. The entered number is invalid. [Err 101]", when I type IMEI from box my phone, there is no error. There is possible to change the IMEI manually? I tried this method http://forum.xda-developers.com/showpost.php?p=2354610&postcount=362, but in Service Programin I don't have tab NAS :/
