Member: 1656305 Status: Offline Sonork: 100.1624503 Thanks Meter: 48 | Wifi problem after unlock/default efs/imei? Solution here Tested in Note3 sm-n900 and S4 i337(m).. 1. Root your device with any method you like... (cfroot, kingo, etc) 2. Install root explorer 3.0 (or any newer version available) 3. Open root explorer and locate EFS folder (dont forget to mount as R/W) and Delete it (it maybe will say error, just try again) you know it is done when you press power button to turn off (it will power off without select power off option) 4. Repair imei/unlock with spt of course and after that.. wifi will work again... Tested by me.. sent from my sm-n900 using tapatalk |

Member: 2151640 Status: Offline Thanks Meter: 1 | Hey guys, I'm having the same issue on my i337. Could someone explain a few things on the steps of vickcar13 op? I have already installed root explorer and located EFS folder. I don't understand what "(dont forget to mount as R/W)" means. And after that how do I "Repair imei/unlock with spt". Sorry if my questions sound dumb, I am a total newbie... |
