I'm trying to locate the zip file that contains the OTA update for my Droid Bionic. Right now, its failing to update, and every time it fails it deletes the file and I need to re-download it (takes a long time). I was hoping to save off the update so I could try a few things on my phone and try the update. I read online its somewhere in a /cache directory, however I dont see anything at all when I mount it to the PC and do a search for cache or even "*.zip". Does anyone know how I can find the zip file? Maybe I need to change the PC settings or something to search for it (I have changed the folder settings to view hidden files and system files).
Two pieces of ground I want to cover here:
/cacheis typically a separate partition on your device, which wouldn't be mountable by a PC via USB, which is why that isn't working. The USB connection generally accesses a directory named "sdcard" (or similar) which is used as an external storage device, although this storage area doesn't have to be physically external to the device (it may just be a partition named
/sdcardrather than a physical card).
If the OTA is in
/cachethen you should be able to find it with a file explorer or shell on your device. Once you've found it, you could simply move the file from
/cacheto your external storage and then copy it over USB. You'll need root in order to access
/cache, though. There are a number of file explorers that support root access, but I personally use ES File Explorer.
Alternatively, you can flash an FXZ rom image for your current version or later. The benefit of that is that it doesn't matter what state your phone is in or if its missing bloatware that the OTA update requires.
Things you need:
- FXZ image for the desired version (google search for it)
- RSDLite (google search rsdlite 5.7 download)
- Motorola device drivers (found on motorola's site)
- USB cable
My device is HTC One M7 I managed to find the OTA by doing a dumpsys | grep .zip
I was already in a adb shell su session as the file was being downloaded,(after I exited and re-entered the shell and tried to run the dumpsys command I couldn't find it. I'm guessing dumpsys works on a temporary log.)
eventually I found it in the /data/data/com.android.providers.downloads/cache folder
I managed to copy it to /sdcard but it wouldn't show up in Windows Explorer until I unplugged and re-plugged the USB cable in.
I guess Windows doesn't refresh the folder/directory index (or something) to see new files created in there
