D820 only 2G after repair IMEI [Solved] - GSM-Forum

cafonabob1 · 09-27-2015, 16:42

I just did repair IMEI on D820. Everything went OK but now only get 2G data.

I checked forum and solution is to flash some QCN files but the links have been deleted and I don't find these files in support area. Can you please post.

Also when flashing QCN, it says "IMEI on this QCN does not match phone". Which IMEI, keep same or write the one from QCN file?

Thanks!

YEs that is what I assumed and did but only 2G. I need a good QCN file. There are posts from a few months ago on this forum with solution but links were deleted.

Hello.

To repair network, try these different solutions separately:

1. Make Repair 3G/4G. Re-start the phone, insert SIM/USIM card, wait 5-7 minutes and check network.

2. Try to write these QCN files (https://drive.google.com/open?id=0B_...UNIb3d6ek1sZVE, https://drive.google.com/open?id=0B_...UhXZmlQaEhhZ1k). At first, write Repair_1.qcn, then write Repair_2.qcn, re-start the phone, insert SIM/USIM card, wait 5-7 minutes and check network.

3. Try to write QCN file from the Support Area, re-start the phone, insert SIM/USIM card, wait 5-7 minutes and check network.
