Enable OMH/EVDO/Wifi-Hotspot on Spring LG Tribute LS660
To get the SPC, we need to activate the device on Ting (a Sprint MVNO operator in the US).
Use a referral link to Signup on Ting so that you get a $25 account credit. You may use mine if you'd like -- http://bit.ly/varkeyting
Proceed for activation and it will ask you for the MEID and ICC ID, both are available on the box. Go through the steps, enter any US address (maybe use the address of a package forwarder or something). You will be asked to add a payment method, don't worry they won't charge you immediately. Create or use an existing Amazon account for this. Add a virtual credit card and link it to Ting. Once this wizard completes you will get an email with the SPC. You don't need to do anything on the handset. Now you can go to the device settings page in Ting and delete the device.
Once we have the SPC, we can get the device activated directly on Sprint so that the Wifi Hotspot and other features get enabled.
Go to http://bit.ly/sprintact and select "I'm a new customer and I want to activate my Sprint Prepaid phone." and go through the wizard. You need to enter your MEID and it will ask you to confirm the ICC ID. (You may have to wait sometime after you deleted the device from Ting for this to work) Go to the next page, enter the details (use any US address where Sprint has service). Choose the cheapest plan and when it asks for payment, select the pay later option at the bottom. Finish all the steps and you will get an email with your new Phone number. Now power on the device, connect it to WiFi and let it activate. This may take some time as it downloads couple of things. Once the activation, PRL update, firmware update etc is complete you would be able to use the device. Go to the settings menu and see if the Wifi Hotspot sub menu is enabled.
Now we need to enable DIAG mode and then RUIM. @Vinod Nayak has made an excellent tutorial on this, so I am not posting it again. Please check the thread -- http://www.rimweb.in/forums/topic/36748-how-to-change-mode-from-nv-to-ruim-in-any-cdma-phone-using-dfs-free-version/
(You may also want to change the SPC 000000 to remember to easily.)
You can insert the Reliance CDMA RUIM and it should register to network with call and SMS. I used a mini SIM which was cut and didn't have any problems. Few users reported that it did not work with a cut sim. So YMMV.
When enabling data it threw an error for me and few others.
To get data working, I am not sure of the exact change but few of the changes that I had made before it started working are below. I used QPST 2.7.411 for Step 2. (I will update the post with more info once I have the exact changes required).
Changed the NV MCC MNC to 404 00
Disabled Sprint Mobile IP profiles and created a new one and activated with NAI as NET Changed NV Mode to SimpleIP
Handsfree activation popup on every restart. To make it go away immediately, enable Airplane mode, wait few seconds, it would display an error and disappear. Now disable Airplane mode and you can continue using the device (well, until the next restart )I will update the post with more details as we learn about them. I thank everyone who participated in the other thread, for their inputs which helped us in reaching this stage.
