I attempted to install this beta-update, but the installation failed...

What I did:

- tried to install the update, but there was not enough space available

- removed SD card (was configured as internal storage)

- did a full reset on the device, this worked... continued the installation configuration

- after completion, tried to install the update again

- download went ok apparently

- but when the installation started (reboot), the "Android Recovery" menu is shown

- it complains about a file EMMC:/dev/block/platform/mtk-msdc.0/11120000.msdc0/by-name/boot:7665664:e4e2735b891bfee63bf6aa462bb4a201d32a256:8339712:bf63c40c5710ab48b87d23bdc583958dc4fb9527 has unexpected contents.

(note copied this by hand, give me some slack 😉 )

Update.zip is not correct

Installation aborted.

OTA failed! Please power off...

After rebooting the device starts normally, obviously without the update installed.

Mimas — Thu, 15 Feb 2018 16:00:14 GMT

Thank you.

I suppose the date would be

Wed May 17 13:31:54 CST 2017

correct?

Have you flashed the device to version 1.24 or did you get there through OTA updates from an older version?

Re: LIFETAB E691X Firmware V2.8 (Android 7)

vtx — Thu, 15 Feb 2018 16:06:52 GMT

@Mimas, yes that is correct.

If I remember correctly, this was the firmware that was installed on the device when I purchased it (new), back in September 2017.

Is there anything I can do to make it work, the upgrade?

Re: LIFETAB E691X Firmware V2.8 (Android 7)

dlirbo — Sun, 18 Feb 2018 20:00:17 GMT

Ich kann das Update auch nicht einspielen.
Bin auf E691x_20170517_v1.24
Fehlermeldung im bootloader: file ist corrupted
Freue mich auf das Upgrade aber so ....

Hi @vtx, @dlirbo,

thank you for your feedback. We are working on a solution and @TheDoctor will get back to you shortly.

dlirbo — Tue, 20 Feb 2018 07:30:44 GMT

ich habe das Problem bereits gelöst.

Ich habe den medion updater hier uas dem Forum installiert und dann das image aufgespielt 🙂

Wo finde ich den Updater in diesem Forum?

Re: LIFETAB E691X Firmware V2.8 (Android 7)

Mimas — Tue, 20 Feb 2018 14:53:53 GMT

Hi folks,

the following advice is only for devices with Build number v1.24 and kernel version "Wed May 17 13:31:54 CST 2017".

For some of those devices the update to v2.8 unfortunately doesn't work right away. Instead you have to install another update file first.

You can download that file here:

http://cdn.medion.com/downloads/software/full_medion_e691x-ota-V1.24.zip

Copy this file to an sd card or right onto the device and install it via the Updates app -> "Check memory".

The Build number after the update will remain v1.24, but the kernel version will be updated to "Wed May 17 17:38:11 CST 2017".

From here you can install the real update to v2.8 over-the-air as usual.

Please let us know if it works.

Und nochmal auf Deutsch:

Der folgende Hinweis gilt nur für Geräte mit Build Nummer v1.24 und Kernel Version "Wed May 17 13:31:54 CST 2017".

Für manche dieser Geräte muss man leider erst ein weiteres Update einspielen, um danach das Update auf v2.8 durchführen zu können.

Diese Update-Datei könnt ihr hier herunterladen:

http://cdn.medion.com/downloads/software/full_medion_e691x-ota-V1.24.zip

Kopiert diese Datei auf eine SD Karte oder direkt auf das Gerät und installiert sie über die Updates App -> "Gerät durchsuchen".

Die Build Nummer bleibt danach weiterhin auf v1.24, die Kernel Version wird aber auf "Wed May 17 17:38:11 CST 2017" erhöht.

Daraufhin kann dann das richtige Update auf v2.8 ganz normal über das Netz installiert werden.

Lasst uns wissen, ob es geklappt hat.

Grüße,

Mimas

@Mimas and @TheDoctor I can indeed confirm that the proposed workaround (the intermediary firmware update) for kernel build dated "Wed May 17 13:31:54 CST 2017" works.

Thank you both and whomever was involved.

Also note that due to the limited amount of on board storage that the update did not succeed until it was reset prior to the update, and the 1.1GB update image was copied onto an SD card. When this part is completed, the V1.28 succeeds.

Hi @vtx,

glad to hear it worked. That you had to reset the device first to make room for the update is not so ideal of course. Sorry for the inconvenience.

Hope you enjoy Nougat on the E-Tab.

Best Regards,

Mimas

I was enjoying it, but I'm having a problem now with V2.8 I never had with V2.4. The WiFi connection turns out to be unstable.

After having been successfully connected for hours, the WiFi suddenly disconnects, and attempts to reconnect again. The device shows "authentication error". All neighbour SSID's are properly shown. Other devices (smarpthone, laptop) do not have this problem.

Switching off WiFi, and reenabling doesn't work, problem remains. Re-entering the correct password does not work. On the other hand, rebooting the tablet does work! Immediate connection.

The only thing that may be a little odd, is that I put a high continuous load on the WiFi connection by having it synchronised a huge 50G folder/map using Syncthing. Did this before with V2.4 (Android 6.0). Never a problem. Now this issue turned up twice with V2.8 (Android 7.0 Nougat).

Hi @vtx,

pardon me for saying that syncing 50GB files with (or onto? or from?) a tablet device sounds like a rather odd use-case. Or did I get that wrong?

How many times did you do that successfully with the old image?

Re: LIFETAB E691X Firmware V2.8 (Android 7)

vtx — Thu, 22 Feb 2018 11:14:07 GMT

Many times. Never had a problem with that. I like this tablet because it is light and small, and I use it watch movies or series for instance when I am on an airplane, or in the middle of nature in a tent. So, I load these movie files onto that tablet (obviously on an SD card). Seems rather regular use to me.

Re: LIFETAB E691X Firmware V2.8 (Android 7)

Mimas — Thu, 22 Feb 2018 14:46:29 GMT

Hm, I see your point, @vtx. As someone who can appreciate that use case, I would consider moving the data by other means, like copying it onto the SD card with your PC. Or you attach the tablet to your PC (or fileserver) via USB, declare the tablet to be a portable drive, and copy the files that way. Just a thought.

I'm not trying to dismiss the WiFi issue though. We will look into it and if more people show up with similar problems it's priority might go up.

Thanks either way for your feedback!
