Samsung SM-N900A Issue after Cert Write - GSM-Forum

aaydah76 · 06-10-2015, 00:33

After doing a write certificate the phone was working fine. Now it won't make any calls (Emergency Calls Only) I tried flashing a QCN file to fix the issue but now the phone won't even recognize the sim card.

Maybe the cert you wrote is blacklisted?

Do you have the corresponding drivers installed?

The drivers are installed and here are the results that I get. I also tried to use a different certificate and the same error occurs.

Do you have adb/fastboot drivers installed?

Yes I do. I always use the same computer for this process..

Does the fact that I have null IMEI have anything to do with this?

I was actually looking at that right now. On the phone does it display NULL when you dial *#06#?

Yes it does.. I think this was cause because I tried flashing a QCN file that was intended for N900T. Not sure if the issue is related or not.

No I believe the QCN doesn't affect that, I've tried that with other devices it doesn't affect it. I believe the phone has a damaged EFS OR it has a damaged Baseband. You may want to reflash the phone to stock rom, you can find the file in the support section.

As You can see from your Software log, phone's modem part is damaged:

Quote:

SW version: Unknown

This can be Software (modem firmware or EFS is damaged, or You have written unsuitable firmware) or HW problem.

You should re-flash the device with different firmwares and check, whether modem is correct (not Unknown). And only then (when phone's modem part will be correct) perform "Write Cert". It is not possible to repair IMEI, if phone's modem part is damaged.

If after of writing all firmwares, which You have, phone's baseband is still null or unknown (SW version is Unknown) - most likely, this is HW problem (problem with eMMC flash chip).

Could you tell me what files I need to flash? Just the AP or do I need to flash something else? I tried this (Including the PIT, BL, AP, CSC) but that didn't work. Guides - Post #2 - XDA Forums

You should try to write different available 4.4.2 and 4.4.4 firmwares. We can't say which firmware exactly will help for your particular phone.

I am going to try 4.4.4 (It's currently running 4.4.2).. Could you tell me what files I should flash? Should I just do the AP file or are there others?
