Problem with FW 20170829.121614.V0321
The question is: Monday falls oder defective batch? I think the picture is not clear yet.

I have the model with sec701, cant seem to flash anything on it anymore. It bricked itself after the latest ota 20170919.150557 was installed. I managed to get it to show over usb by shorting pins 14-15. Cant seem to finish a flash successfully, getting this error "uboot/partition logo/verify partition/error result". I even tried my restoring the 0829 and its failing on same spot...

[P.X]

I have cautioned many times now

How many people with initial FW 20170829 have got a box that flashes even once without becoming borked/bricked/useless ?

What are the Memory chips ?
What is the eMMC chip ?
etc.
Please give details as requested above if possible ...

Has anyone with freezes tried this?
"you can put into one more capaciator 22uf/0805 6.3v on position 1c40 all wll good"

I found it as a comment in this video

Here is the thread that discusses this - http://4pda.ru/forum/index.php?showt...ost&p=63415661
Open in Google Chrome and use the 'translate' feature
Have come across several references that have validated it works.

Here is the origin - http://4pda.ru/forum/index.php?showt...ost&p=63158281

Note however that this is for the PRO 3GB/32GB - the S912 box.
This freezing issues being discussed also predates the current issue with the most recent Pro+ boxes
=> I don't believe is applicable to this box (Pro +)

Also, SEC 701 and SEC 713 seems to be the same product and share the same modell number: KLMAG1JENB - B041. Maybe just different revisions/steppings?

At first glance the 701 and 713 look like date codes, i.e. "713" would be week 13 of 2017.

Can you please post a photo of the board and which pins you shorted? I also have a bricked device which only shows the red/blue standby light when plugged in. I cant get it recognised by USB.

Just noticed a new Mecool M8S Pro L

MECOOL M8S PRO L YouTube 4K Streaming 3GB/16GB Android 7.1 Amlogic S912 KODI 17.3 TV BOX 802.11AC WIFI Bluetooth LAN HDMI - Black

with Widevine Level 1

Chances of a nice Magendanz ATV ROM

???

Like other people here, I spent hours to make this box work properly without success. The worse device I came across (among many).
My suggestion is not to buy any MECOOL devices at all.
Spec and price may look tempting, but if software is bad (in addition to HW issues), the box is useless still.
I have additional Mi Box from Xiaomi and it works like a charm out of the box.

Yes, that sounds logical.

It was updated on M8S_PRO + -ota-20170919.150557.V0619 (box on amlogix s905x 2 / 16Gb M8s pro + Flash SEC 652)

From the card microsd did not want to update, inserted through the card reader into the usb port and updated via the application UPDATER

In the section about the device: M8S PRO + userdebug7.1.1 NHG47L 20170919.150557.V0619

Interface like without lags. Working HDMI-cec with LG, but as with all the boxes is not complete, the prefix only knows how to go to sleep with the TV turning off the remote control.
There was a Google Cast item in the Android shutter, but it does not work ) The device is displayed as M8S PRO + but it does not translate to it. Checked and in the settings of the android and through third-party software localcast, the connection is not established. With relatives in boxing air, miracast works.

Removed HDMI selfadaptation (which by the way did not work). the framerate does not work

I have stopped getting email notifications from Freaktab ! Anyone else ?

Hi,

Thanks to Magendanz for all the effort on these FWs
I flashed the recovered 08.29 OEM IMG but the bad box is still a bad little box - freezes during the Mecool Splash Anim.
Worth a try.

It's the same pins as the z69 (pin1 has triangle symbol), see magendanz post here http://freaktab.com/forum/main-categ...310#post673310

So, these eMMC chipsets include both the NAND flash storage and the eMMC controller on the same die. One of the features introduced in the eMMC 5.0 controllers is a Field Firmware Update (FFU). My guess is that an FFU could be used to correct the problem with this defective lot. If I were gearbest, that's what I'd be asking the factory for.

BTW, this isn't the first time Samsung eMMC controllers have had serious firmware issues: https://forum.xda-developers.com/sho....php?t=1693704

WARNING: There's is a possible bad batch of M8S Pro+ boxes which are experiencing regular freezing and crashes. We've narrowed the source of the problem down to a Samsung eMMC 5.1 chipset (KLMAG1JENB - B041), batches SEC 701 to 713, and these usually shipped from the factory with version 20170829.121614.V0321 of the OEM firmware. If you have one of these, it's highly recommended that you not flash any ROM (custom or OEM), as the prolonged block writes seem to result in serious data corruption.

By request this was posted.

I am sorry but Id consider this a manufactures defect and they should replace any affected. Mecool should offer replacements to units affected.
