Member: 90682 Status: Offline Thanks Meter: 21 | I did search and it seems like this Samsung S4 has similar or same M/B as AT&T Samsung S4 (SGH-I337) GSM.... [Not CDMA (Tracfone)] Also, I saw on Youtube that a Vietnamese guy posted Unlock and use GSM for this Model#: SM-S975L (Samsung S4 Tracfone Straight Talk USA)... Let me check and update with a Youtube links later on... Here is the link [Not sure if I'm allow to post a link or not] How Unlock Samsung TracFone Straight Talk SM S975L Galaxy S4 https://www.youtube.com/watch?v=1MWysLoRPFM @stanner Any idea what he did? Or did he reset the Unlock to 00000000 [8 zeros]? Last edited by dtkool; 09-28-2016 at 01:42. |

Member: 90682 Status: Offline Thanks Meter: 21 | Nope... I think there is a TEMP UNLOCK Solution with Unlock Code. However, everytime you reboot or restarted the Galaxy S4, the phone will be RELOCK. You will have to Retype and Re-Unlock it again. I'm still looking for a PERMANENT UNLOCK Solution for this Model (SM-S975L) Here is a youtube video showing a Vietnamese guy unlocked. (Not sure this is permanent unlock solution or not): https://www.youtube.com/watch?v=1MWysLoRPFM Anyone or GCPro Key team care to work on this Samsung S4 Model: SM-S975L ? |
