  • Instructions for installing a kosher ROM on TCL Flip2/Classic T408DL

darth hey is it possible that everything works but calling doesn't? even texting is working in both directions. but calls in/out don't work. wondering if that's even a possibility with a "bad" ROM rather than apps not launching/working/etc. Or do I need to do anything for it to work?

      flipperk [Login to see the link] The calls are actually working but sporadically. Moving to new SIM doesn't help. Still curious if you think the culprit may be this 4058W ROM I used or do you think it's unrelated? Thanks.

          Jumptoheaven this is on Tmobile, a TCL Flip Go 4058W and I'm able to swap SIMs around without any issues. I moved two of my lines to this model phone. The first is stock ROM and has no issues. The second is this ROM and has these intermittent call in/out issues (texts seem to be fine). I'll also notice dropping from 4GLTE to 2G etc. So it may just be a bad phone coincidentally and that's why I'm asking if a "bad" ROM could exhibit these kinds of issues. (Everything else is working 100% btw).

              flipperk As I mentioned earlier I dont have a 4058W and never tested anything on it. Im not sure what is causing your issues.

                  darth I understand that. What I'm trying to figure out is if the ROM is "bad", is it at all possible that it would exhibit itself in this manner? Or is the only way a "bad" ROM presents itself is the inability for the phone to boot or app that crash, etc. rather than an intermittent voice network issue.

                        flipperk I dont modify anything that should effect the service. But I have never tested it so I cant say for sure it has nothing to do with my Rom.

                              Any updates about, if the kosher ROMs of the phone will update to have the KEFH software version?

                                darth is there any way that I can help you to help me with this? cant have the kids running around with a browser on these 4058W phone. Thanks! Also, is there a way for me to revert back to the factory ROM on this
                                "bad" kosher phone (I have another 4058W with factory ROM).

                                    will this guide work for the 4058g?

                                      does anyone know how to add an app to the rom before flashing it

                                          zlate The installation of these Roms deletes all installed apps.

                                              "Run Auto Booter".
                                              In command line, I ran mtkfastboot.exe, got error:
                                              Found MTK Preloader Port on COM4
                                              Running MTK Fastbooter on COM4

                                              b'READYTOO'
                                              Entered fastboot mode on port COM4
                                              Traceback (most recent call last):
                                              File "lion.py", line 97, in <module>
                                              AttributeError: 'Thread' object has no attribute 'success'
                                              [46576] Failed to execute script 'lion' due to unhandled exception!

                                              However, even with that error, when I plug in the phone, it did go into fastboot mode.

                                              I was able to proceed to run these commands:
                                              fastboot flashing unlock
                                              fastboot flash --disable-verity --disable-verification vbmeta vbmeta.bin
                                              fastboot flash --disable-verity --disable-verification vbmeta_system vbmeta_system.bin
                                              fastboot flash --disable-verity --disable-verification vbmeta_vendor vbmeta_vendor.bin
                                              fastboot flash boot boot.bin
                                              fastboot reboot fastboot

                                              BUT, the cmd window stuck at:
                                              Rebooting into fastboot OKAY [ 0.001s]
                                              < waiting for any device >

                                              On the phone, the screen shows
                                              [Login to see the link]

                                              Which option do I select? It does not matter which option I select, the CMD fastboot is stuck on < waiting for any device >
