[Android General] JesseAaronSafir:
Help please. I have 5.0.11 rooted. I had the OTA notification and manually downloaded both US_ME302C-V5_0_16-0-ota-user.zip and US_ME302C-V5.0.17-0-uta-user.zip. I placed the first one (793MB) on the root of the internal sdcard and disconnected USB. This did NOT get the update notification triangle to appear. I also tried Settings->System Update->Check now and I get nothing. I also tried rebooting into the bootloader with power+volume up and I'm not seeing it update there either. Then I installed fastboot via method 1: http://xdaforums.com/showthread.php?t=2588979 and it appears to install fine. I'm running Windows 7 64-bit. But Device Manager didn't show the ADB device so then I tried installing these device drivers: https://secure-software.intel.com/en-us/system/files/article/458818/intelandroiddrvsetup1.1.5.zip and it didn't show up immediately but at least it was able to find drivers after that. Now Device Manager show the ADB device and "C:\adb\fastboot devices" shows the tablet with a S/N that's all 1's. However, "Fastboot update US_ME302C-V5_0_16-0-ota-user.zip" doesn't seem to install either the copy that's in the C:\adb folder or the copy that's on the root of the internal sdcard on the tablet. I am getting an error:

C:\adb>fastboot update US_ME302C-V5_0_16-0-ota-user.zip

archive does not contain 'android-info.txt'

archive does not contain 'android-product.txt'

error: update package has no android-info.txt or android-product.txt

C:\adb>

What am I doing wrong? Could I rename the zip to ASUS_BUNDLE.zip and use the "SD DOWNLOAD" option in the bootloader? Would I put this on the root of the internal sdcard or on the root of the external sdcard?

Ugh...renaming the firmware file to ASUS_BUNDLE.zip and placing it on the internal sdcard did not update in the bootloader. But then I tried moving it to the external sdcard and that seemed to take. Unfortunately, it wiped /data and I'm still at 5.0.11 for some reason.

After it came back up with 5.0.11 I got an OTA update prompt, which I accepted. It downloaded it and started installing it rebooting to recovery and then came back up and it still has 5.0.11 on it. Settings->About->System Update doesn't show an update available.

Next I tried this:

C:\adb>fastboot flash update US_ME302C-V5_0_16-0-ota-user.zip

sending 'update' (793307 KB)...

OKAY [ 97.778s]

writing 'update'...

FAILED (remote: problem with creating ota update file!)

finished. total time: 100.940s

C:\adb>

The tablet reports:

Edit: I found earlier in the thread that you have to downgrade fastboot to 4.7.3 in order to flash an update so I did that and then I was able to flash the 5.0.16 via fastboot. Progress! And now after getting up to 5.0.16 I was able to drop the 5.0.17 root update onto the internal sdcard and after rebooting it was prompting to install, I did it and now I have 5.0.16 rooted. WHEW!

I'd still like to know what I did wrong in the first place.

Now that we have 5.0.16 rooted, has anybody noticed any difference over 5.0.11 other than no longer getting nagged to accept an OTA? I see it's still Android 4.3. Build number is JSS15Q.US_epad-V5.0.16-20140226. I did a Google search for a changelog and I'm not coming up with anything. Any performance improvements?
