Galaxy Note 2 shows no sim card after radio flash I have the SGH-T889 (T-Mobile USA version of the Note 2). When I got my Galaxy Note 2, I loved the device, but disliked the software. So, I decided to flash CyanogenMod 10 build from the N7100 forums. Although many things worked, the radio did not work. So, I decided (in my infinite wisdom), to dd the radio from the Stock SGH-T889 T-Mobile rom to the /dev/block/mmcblk0p10 partition (http://forum.xda-developers.com/showthread.php?t=2039081).

This did not work, so I installed the stock SGH-T889 rom just to get it back to working order. However, my sim card was no longer being detected. I have tried flashing other roms to try and get the radio back, but alas all say that there is no sim card.

I realize I have probably permanently messed up my phone. Does anyone have any ideas or things to try to get it back to working order? I am out of things to try.

UPDATE: I have tried everything you guys have posted, and ended up sending it back to Samsung and get them to fix it under the warranty. I believe they replaced the whole motherboard, so I will never know exactly what the problem was. If you decide to send yours back, make sure to reset the binary counter that you see in download mode. There are guides around the Internet for this. Thanks for all of the help.
Get the ODIN package from here. Then use ODIN to restore to "True" Factory Stock. This will put you back to stock (but will not reset your flash counter). Then from there you can start and use ODIN to root the device again, flash CWM and flash custom ROMs. The modem/radio you linked to should be the radio that you will want to flash if you flash an N7100 ROM. But, as you can see, I would stay away from ROMs that are not for the specific model. the T889 has a couple ROMs based on the stock N7105, but there have been changes (things like the radio) replaced with versions that are for the T889.

I eagerly wait for an AOSP build (specifically CM) for the T889, until then, I am running one based off the N7105 with the Bullet Kernel by cmenard. This kernel has the modules for CIFS support, which I use constantly.
