Zmax Pro - Process System problem - Can I reinstall Android files?

terrimareeterrimaree United StatesPosts: 3 ✭✭

I would like to reinstall Android if I can. During/after an update my phone was low on memory. It rebooted itself while in use some days later. I ended up deleting some apps and some app folders (or so I thought). I might have deleted too much, and gotten something from the Android system, or the update did not install right??

I started out with the ZTE being from Metro PCS but the phone has been unlocked and been using it with Cricket for about a year. I'm not sure if updates come through as Metro PCS still. I'm assuming so. I have the Metro PCS apps that will not remove, and manually installed the Cricket apps that I wanted.

Now I have 7 GB free storage on the internal memory, but every reboot says:

            “Process system isn’t responding. Do you want to close it?” 

Whether I select “Wait” or “OK’ I can use the phone, but I can only use one app at a time and have to use back button to back out of everything I have done. If I open something that has a link, it can’t even figure out how to open in in Chrome browser which is still installed.

My quick settings changes do not work. I can only swipe down once and see four settings and Display brightness. Settings Gear will not open settings from here. I have to go to All Apps button and find Settings to open it.

I would like to reinstall Android system, but don't know how... I need a zipped file or something? I am afraid a hard reset wiping all my other things will still not work right because of possibly some missing files (if I deleted something I shouldn't have) because of the current behavior.

Android version 6.0.1
Android security patch level August 1, 2017
Baseband version Z981B01
Kernel version [email protected]
Build number Z981V1.0.0B21
Hardware Version u88A

I would love it if I could just get a legitmate Android system file to reinstall, or at least the last update file might help fix the problem. I test software as my job, and we reinstall things over the top all the top. This really seems like messed up/missing files to me, but I'm not sure what kind of files would be available to try to reinstall. I'm hoping something. I am really fearful a full reset will not fix this and will just lose my data.

    hi, unlike desktop OS where you can reinstall everything from scratch, mobile OS typically just do a reset and it will return the phone to the stock setting. Mobile OS has its system files hidden in a separate partition that typically is not user accessible so you should still have those files protected.

    In your situation, I would say, back up everything and just do a reset and afterwards, just start with minimal apps that you need and then you can decide what other apps you would like to install.

    Oh yes, it should be up to date, but I don't trust the install actually installed properly.

    For a reset, that is a lot of likely impossible work to do a backup since I cannot connect it to a PC with the process system not working. I cannot even select "Connect to PC" to try to do anything with USB settings and the phone won't show up in the computer's file system.

    I don't trust moving that much to the SD card because of all the problems I have trying to copy or move just small amounts of files and file sizes. I've even had to reboot with File Manager not responding.

    I don't really trust the Android system to do a correct hard reset. I just want to reinstall the update if I can.

    In System, About,
    there is a "Storage card updates" that says under it "copy update package to storage card for system updates". Selecting that says:
    "Please copy update package to root directory on storage card, then click OK button."

    That is what I would really like to try first since backing up my files is not a simple option.
    This makes it sound like there should be something like an or FileName.update that I should be able to put on the SD card.

    @terrimaree , you are correct that you can use the update to update via microSD. However, I do not believe there is a flashable file for your particular device as it is done via over the air. Factory reset is probably your best option

    In this case, Free up Phone Space is the first thing you have to do. Followed by Reboot Device, Move Apps from SD Card to Internal Storage, etc., there is always one that can fix "process system isn't responding".

    I did end up doing a factory reset. Turns out I did have a bad SD card. I'm not sure when that happened and if it was part of the initial problem. After doing factory reset I did still have some trouble, but not like before. It's much better since getting a different SD card, so that may have started all of my trouble.
