Honeywell Dolphin D 75E Android 4.4 KitKat to 6 Marshmellow, add gms, g play services

Hello XDA,

New to posting on the forum.

I have a Honeywell Dolphin 75E smart phone running Android 4.4 (Kitkat) however it is non-GMS (google mobile services) version so it does not have any google apps or services and no google play.

I’ve sideloaded various apks, latest versions of google play store, google play services, google play framework, google account manager, but found that the latest compatible version of google play services would enter an almost continuous “Google Play Services has stopped” loop which made the device essentially unusable because of the constant error preventing you from doing anything else.

So, I installed earlier version of google play services (from Spring 2018?) and was able to reduce the error to almost never and could now open the play store but get a “error retrieving information from server. DF-DFERH-01” error in google play store with a “retry” button, however I can access the left side bar and settings on google play store but not any apps or content.

I researched online how to resolve the “google play services have stopped” error in android and the “DF-DFERH-01. Retry” error in google play store and tried all possible solutions mentioned such as force stop, clear cache/data, uninstall, reinstall, reboot, etc but nothing improves.

Since the google play services has stopped error is occasional with the older version, I was able to sideload Chrome & many other apps some of which work perfectly, however, some latest compatible version apps when opened state that they won’t work unless a newer version of google play services is installed and then they immediately close (even though I can see their content loaded and working before they close, for example YouTube). Again, when I update the google play services to the most current compatible version (compatible with arm7 Android 4.4 and the device dpi or non specific generic versions) the google play services has stopped error becomes non stop and renders the device essentially useless because the error message pops up so frequently that you can’t actually do anything else other than close it again and again.

I’ve done weeks of research on how to fix the error and even contacted google support but the response is always the force stop, clearing cache/data, uninstall, reinstall which I have already tried. I can obviously keep using older versions of some of the apps however they don’t have the same functionality in some cases, so I would like to fix the errors with a newer version of google play services so I can install and run newer apps directly from the google play store rather than side load apks from online... for example, google chrome says it won’t work unless I update google play services but then it actually works anyways; google duo requests newer version of goggle play services regardless of whether the version of google duo is years old or current, and refuses to work beyond the message to update google play services; Google home version that allows smart lights devices requires newer version of google play services to work and the older version of google home that does work with current older version of google play services, doesn’t work with the smart lights, for example.

I’ve researched and the D75E comes in both android 4.4 or android 6 versions and each can be either with gms or non-gms versions (google mobile services), so I know that the device can have android 6 with google play store.

I found instructions online on how to upgrade the D75E from android 4.4 to 6 however the instructions are from Honeywell Aid and the file download links to a file download site that requires a Honeywell account login presumably for the administrator of the purchased licenses. Since this is a device someone gave me that is not sold at stores but rather to entities for the specific purpose of being used as a handheld barcode scanner, I don’t have the Honeywell site login information or thus support from Honeywell.

Most of the information online about adding gms to non-gms android pertains to Huawei and other Chinese phones running android 7 or higher and cyanogenmod and lienageos don’t seem to have the 75E for obvious reasons.

So my questions are:

1) how do I fix the “google play services has stopped error)?

2) how do I run apps that require newer versions of google play services”?

3) where do I find any rom with android greater than 4.4 for this specific Honeywell dolphin 75E device or can anyone help me get the 75E GMS file:

D75-M-69.01.17-(0285).zip?

Here below is some information copied from the Honeywell link that comes up when you google search upgrading the 75E from android 4 to android 6:

Android 6 License .xml file

When upgraded the CT50 and D75E from Android 4 to Android 6, an upgrade license is required.

The license .xml file has to be copied over a USB link in the root of 'Internal Storage', which is equivalent to the internal mount point '/sdcard'.

License is no longer required starting with Android 6 kernel version:

75E GMS: D75-M-69.01.17-(0285).zip

75E Non-GMS: D75-M-68.01.17-(0285).zip

CT50 GMS: CT50-M-71.01.17-(0285).zip

CT50 Non-GMS: CT50-M-70.01.17-(0285).zip

Any help would be appreciated, thanks!
