[Q] No imei, possible to fix without service center? - Galaxy S II Q&A, Help & Troubleshooting

Hi!
My imei just suddenly disappeared one day and I have been trying everything I could find on this forum to fix it. My .nv_data.bak files (in /efs folder) seems to be fine (from the date of the file), but I think my nv_data.bin files is corrupted. Have tried the methods of using the .bak file to restore the imei, but havn't worked.
I sent my phone to the service center, and they told me that they had to change the motherboard on the phone to fix it, and it would cost me 500USD+.
Is there a another way to fix the phone without changing the motherboard? Can't see how changing the motherboard can cost over 500USD when the phone itself cost 750-800 USD.

PM Odia, he'll sort you out.

Why you must pay if your phone have 2 years warranty?

You void your warranty the minute you flash a custom Rom

Talked with Odia now. Since my imei is blank and not 0049, the only way is to change the mainboard. Bah

Try this: https://market.android.com/details?id=com.helroz.GSII_Repair#?t=W251bGwsMSwxLDIxMiwiY29tLmhlbHJvei5HU0lJX1JlcGFpciJd
I assume no responsibility.

Yeah, thought about it, but can't access the market when my imei is broken :/

Doesn't that tool more less just copy the /efs folder to /sdcard, (re)format it and copy everything back (i.e. fix the corrupted filesystem)?
If that's the case, you could do those steps via adb or terminal emulator app.

Exactly but I'm not sure how clued up the OP is so I offered him an easy option.
@OP can you not connect to the market with WiFi?

@ HellcatDroid I've tried that method with adb shell, but didn't work.
@ Intratech When I try to open the market app, a white screen just pops up in half a second, and the app close itself.

I should add that function to kTool too, I think.... shouldn't I?

Go for it mate. I like the work you're doing.

Erm, try going to applications in settings and clearing the market data and see if that fixes it.

Hm, still can't get access to market. Isn't possible to download GSII_repair on PC and put it on the sdcard with USB?
