There is another way to prevent the error which would be by preventing the parent if statement from returning true. One variable which is checked is the this.mEndurance variable.

This variable is set with this line of code: packageManagerService.mIsEndurance = SystemProperties.getBoolean("ro.vendor.tct.endurance", false); So if we can somehow modify the system property ro.vendor.tct.endurance to return true then we can bypass the check and install the package!

This is where our developer is currently up to, if you have any cool ideas on how to modify this system property without root then by all means let us know!

      Apps4Flip-Admin If you can figure out how to get this phone into download mode than you should be able to root or create custom firmware (kosher?) for the phone.

              Apps4Flip-Admin This is way more confusing then תקפה כהן! I'll still try to get through it. But, how do I dial the 2880. Just call 2880? Are there stars and pounds?

                use the hashtag and star pattern from the other commands, but it still won't work because of the second issue I brought up

                  Apps4Flip-Admin Installing APK won't work? Or the code won't work at all? (I didn't see anything when I pressed it).

                    Its a system property and there is no way to see that it changed besides for running adb shell settings get system install_enabled

                    Before running that code it is set to 1 and running the code sets it to zero.

                    This allows the check in the code to pass. Now we just have to get passed the other check!

                      SamFried Can you provide link to the phone on Amazon.com?

                          SamFried I'm not sure it's true, but if I get a chance to try I'll let you know. It may be true.

                            Does it work on Sprint/T-Mobile?

                              Reifam Most of us will not know because only Tracfone is selling the phone, and it will be locked to their network until you use the phone with their service for 60 days, then the phone can be unlocked for use with other carriers. The phone just came out so we don't have any testimonials yet. Verizon bought Tracfone and Tracfone traditionally had phones that worked across all 3 of the different carriers (although your service would be with Tracfone, it may have used Verizon, T-Mobile or AT&T network), however Tracfone is slowly moving customers onto Verizon-only devices and SIMs that strictly use Verizon's network (my hypothesis is that Tracfone will become Verizon Prepaid one day).
                              For now, if you're looking for a T-Mobile version, check out the TCL Flip Go [Login to see the link] it is nearly identical to this.

                                  This phone also uses the Kika 12key-keyboard which has a pretty bad T9 dictionary. Try to type "I'm" for instance, the only suggestions are in, go, etc. It would be really nice if this keyboard dictionary could be updated somehow

                                  knopper If T-Mobile has a version and Cricket has a version, wouldn't that mean the TracFone one works with those towers?

                                      Biden2020prez no not necessarily. For one they are different model numbers so the 2 carriers are not selling the same phone. Secondly, the LTE bands are different between the models. You need certain LTE bands such as band 71 to work well on T-Mobile. This band is not on the Tracfone model. Tracfone’s since shifted their focus to providing service that strictly connects to the Verizon network so the addition of band 71 is not a necessity on their phone. Hope this clear things up

                                          knopper Yes, that clears things up. So if I get this phone unlocked, I can't use it on T-Mobile?

                                          Pretty smart to have a decent unlock policy, but make customers forced to your network even after the phone is unlocked...

                                              You probably can use it on t-mobile, but it just won't work as well, due to the missing bands

                                              Biden2020prez My bad, I just looked into it again. The Tracfone version (model T408DL) actually has band 71, so is all set for T-Mobile. I had it the other way around....the T-Mobile version (model 4058W) does not have band 13, which is very important for Verizon (it's Verizon's low band that allows for better indoor coverage and better rural area coverage). So actually, the T-Mobile version would not be good to try to use unlocked on the Verizon network. However using the Tracfone version on T-Mobile would be fine in your and Reifam 's cases.

                                                  How can you see what bands are on the phone? Also, is there a list of what carriers use what bands?
