[Verizon Galaxy Note 4 Android Development] syrenson:
Constant app crashing and Wifi problem

Greetings All,

I recently rooted the boot loader in my Samsung Note 4 SM-910V and installed TWRP. Following this, I was able to successfully install a modified version of the Verizon stock ROM for this device (one that does not overwrite the boot loader). This ROM was fully functional and apart from a slightly different bloatware distribution, it was identical in form and function to the software that came on the phone.

This said, my reason for rooting the phone in the first place is that I would like to run Cyanogenmod 13 with Android 6.0 on my Note 4. To accomplish this goal I downloaded the 2016-06-20 build (cm-13.0-20160620-UNOFFICIAL-trltevzw.zip) from this thread, ensured that the file was not corrupt, and uploaded it to my phone. I also downloaded the ARM 6.0 stock Gapps from Open Gapps (open_gapps-arm-6.0-stock-20160621.zip), ensured the file's integrity, and uploaded it to the phone. Next I followed these steps:

1.) Booted the phone into recovery/TWRP

2.) Selected Wipe > Advanced Wipe and wiped Dalvik Cache, System, Data, and Cache. (got succeed message)

3.) Selected Install and chose the cm-13.0-20160620-UNOFFICIAL-trltevzw.zip (got succeed message)

4.) Selected install and chose the open_gapps-arm-6.0-stock-20160621.zip (got succeed message)

5.) Selected Reboot System

This lead to the ROM booting and going into the welcome/setup wizard but I immediately started getting flooded with "Unfortunately X app has stopped" messages. I brute forced my way through the setup wizard while clearing probably twenty "app has stopped" errors along the way. Once I was actually in the OS proper the barrage of errors made it practically impossible to accomplish anything. Opening Google Play Store resulted in it immediately crashing.

Upon doing a bit of research it was suggested that these errors might be eliminated by choosing a lighter Gapps package with the bare minimum required to access the Google Play Store. As such, I repeated the above process from scratch (wiped/reinstalled the ROM) and installed open_gapps-nano-6.0-stock-20160621.zip. Unfortunately this resulted in the same barrage of "app has stopped" messages. Doing a bit more research, I tried a number of suggested fixes for these errors including: resetting automatic time and date, clearing data and cache for Google Play Store, Google Play Services, and Google Services Framework, and attempting to clear the the cache for all apps via the Storage and USB submenu. None of these solutions worked.

Next, I decided to wipe and install the ROM without Gapps just to ensure that Gapps was truly the offending party. It turns out that Cyanogenmod13 itself was also plagued with these errors. In particular, after wiping and reinstalling the ROM (without Gapps), and booting into the OS I started getting repeated "Unfortunately app has stopped" errors for the "CM Updater" and "Settings" apps. I did some research on this and all that I could find is that the CM Updater bug has been fixed in the nightly builds. My understanding, however, is that the Note 4 isn't supported by those builds and therefore we need to use the ROM included in this thread.

As an aside, I also had problems getting Wifi to turn on and actually find local networks.

Since this is my primary phone I ultimately wiped Cyanogenmod 13 and reinstalled the modified stock ROM so that I can receive calls and messages. I am, however, pretty bummed as I was really looking forward to running Android 6.0 without all of the bloatware. If anyone has any suggestions on how I might go about a more successful second attempt at installing CM13 on my Note 4 SM-910V, I would greatly appreciate it.

Kind Regards
