So, I got one of those obama phones. And it was fine.....until it broke. So, I decided to try and make it work with my US Cellular Moto X. I found this guide and followed it. I was able to make calls and texts....However no data. Which annoyed me. So, me being me, I decided to keep going until it stopped working I tried flashing it, flashing just the modem, I even looked into NV values, bands and whatnot myself. Being a programmer and having worked with hardware many many times in the past, it wasn't too difficult to understand. However, try as I might, I cannot get it to work again. It detects the SIM card, I see the number, and it even says I have voicemails.....However I have no signal. I'm completely puzzled. As far as I can tell from typing *#*#4636#*#* it is in using GSM. and I tried many different ones. Any help is greatly appreciated. As of now, I also tried flashing a different kernel and then just decided to flash CM13 thinking maybe there was a lock in the kernel.....No luck. UPDATE: I trimmed down and put in an old straight talk sim card and it gets bars and it will call....the call obviously won't go through XD but it will call. So, I'm stuck....

Remove SIM and switch off phone 2. Boot into bootloader mode and select BPTools, after phone boots, enable debugging 3. Map the comports correctly to QXDM 4. Airplane mode 5. In QXDM, open command prompt, type spc=000000 6. Open NV browser, look for item 441 and make it 0x383 or 0xFFF in band line, click write 7. Look further for NV item 946, write 0x0028 in band pref 8. Lastly item no 1877 and write 2622339 to rf_bc_config line 9. Reboot 10. Phone now boots in global mode, insert GSM SIM and use with EDGE data. CDMA section remains untouched. Part II:- 3G HSPA+ UMTS 2100 mhz unlock (part II only after getting Edge signal) 1. Select LTE from mobile networks settings. Remove SIM and switch off phone 2. Boot into bootloader mode and select BPTools, after phone boots, enable debugging 3. Map the comports correctly to QXDM 4. Airplane mode 5. In QXDM, open command prompt, type spc=000000 6. NV item 946, write 0x0EA8 in band pref 6. NV item 1877 and write 245891456 to rf_bc_config line 7. Full flash current firmware by fastboot with emphasis on fastboot erase modemst1, fastboot erase modemst2 8. Phone boots in global mode with HSPA+ Note:- Firmware flashing will remove unstable signal issue. All the changes will be permanent. CDMA/evdo remains as it was earlier.
