[ROM] Mecool M8S PRO+ TVStock Nexus ROM (Android TV 7.1)

[Rafaluke]

Hello Magendanz.

I'm still having issues with my box. The HDCP is saying Unprotected and due to that some videos app's keep crashing. I'm wondering if there is something that I could try to revert back the HDCP to protect again.

Any ideas? I have made some searches and found someone saying that can be possible, but haven't reply back regarding what to do...

Can't think in any use of the BOX if it was not able to revert back the HDCP...

Thanks.

Hello Magendanz, thank you for your reply.

Well, I'm sorry to hear that. Dont have a clue about what happened. I'm completely sure that I have followed the instructions for the firmware updates...

I've got in contact with Gearbest support, stating the problem. The support have requested to install a stock firmware, 20170715 .093046.V0321. They have sent to me a zip file, but when I tried to update by USB, the box not allow me to proceed saying that I cant install an older firmware version. Since I dont have a .img file to overwrite with USB burning tool I'm wondering if there is a way to roll back a firmware with .zip files?
Ive tried to find a .img file with this exactly oem firmware but no sucess.

Even knowing that this operation probable will not work, I would like to take a try. Can you help?

Thank you.

Yeah, their update script won't allow a downgrade. You'll find an archive of some older OEM firmware releases (some of which have had their scripts "fixed" and some burn packages, which won't care) here: http://freaktab.org/27~f

Hi.
I'm interested in changing the launcher but I've read that on Android TV you can not change the Launcher. Is there any way to change the Launcher in this ROM?

Thanks.

You can change the launcher on an Android TV build. In fact, that's what the OEM did.

Hi,

I would like to ask you for some help, because I am stucked.

I installed the system successfully(3.0.x-x twrp), everything was working fine, but the videos were full of pixels and “felling apart”. So I decided to do a reinstall and created a backup. I installed 3.1.1-0 and erased the hard drive. I am getting the following error message when I try to install it.
"*** Install Amlogic firmware update ***

- Confirming target device...
file_getprop: failed to stat "/system/build.prop": no such file or directory
Updater process ended with ERROR: 7
Error installing zip file '/usb-otg/update_M8S_PRO+-V0619_TVStock-171001.zip'
Updating partition details...
...done"

It wouldn’t be a problem, if I could install the backup, but because of the twrp update it won’t recognize the older backup. I even tried to use an older twrp version, but in this case it won’t run at all.
Here I am stucked.
Could someone create a backup with 3.1.1-0 twrp and upload it for me? Is there any other solution?

P.S Have you ever seen the aforementioned video problem? I haven’t had anything like that before.
Thank you in advance.

The install script on your update is trying to do environment checks by reading the build.prop on the system partition...but you erased that partition. The workaround is to use a burn package (.img file) or comment out the checks in the updater-script that's buried within META-INF.

Note that when you repack the .zip file it will no longer have a valid signature. That's fine when using TWRP to install as long has you uncheck the "Validate file signature" option.

After I flashed and bricked my first device from the affected batch (I did not get the original rom back) I got a new one from Gearbest with SamsungChip (SEC725).
Now the Rom works wonderful. Thank you Guest

Hi,

Does anyone have the 20170825 TVStock OTA zip? I saw a link on this thread but it looks like it has been removed. Would really appreciate if someone could re upload it.

Thank you!!

You mean 20170829.121614.V0321? That was never released as an OTA update, but it did ship on some units. I created the following burn package (.img file) from a backup here: http://freaktab.org/3acc0ea053ee8feb

As far as I know, there's never been an OTA update.

I mean your TVStock version based on the 20170815 firmware. On post #568 ( http://freaktab.com/forum/tv-player-...459#post674459 ) Freud mentions trying an OTA with your TVStock 20170825 rom and provides a link but unfortunately that link is dead.

I'm asking because I have one of the affected boxes that came with 20170829.121614.V0321 firmware, and I was able to flash to both your Nano and Stock ROMs from 20170825 by modifying the update_script to only update boot.img and system, and installing through TWRP. So I think it would be possible to flash the ATV version of that rom if I had the system.new.dat, system.patch, and system.transfer.list files.


Thank you very much for your work on these ROMs!

There's no indication that the TVStock 20170825 release would run on an affected unit any better than the current ones, and they'd be missing some important fixes. Have you tried just installing the latest TVStock OTA update?

I tried latest TVStock OTA and it never gets past the Nexus logo. Same thing with latest OEM OTA. It seems my box is only compatible with V0321 based firmware. I also tried only flashing the system partition of the latest TVStock OTA and leaving the old kernel, the screen goes black after the Nexus logo and hangs there.

[chinubrio]

Are you going to get the HDMI CEC and the Chromecast functions to work in future versions of the ROM?

Google cast is a longstanding issue that may never be solved. The HDMI CEC functionality is inherited from the underlying OEM firmware, so it's really out of my scope.

Where can I find the latest OEM update file 9 (ATV)? Can I update using the TF card?

[P.X]

Post #1 will have a link to the base OEM FW

see: Updated to latest M8S Pro+ OEM firmware (20170919.150557.V0619)

I found your older M8S_PRO+-V0321_TVStock-20170730.zip and flashed the system partition and it worked. It runs great except for choppy/janky scrolling in leanback apps (same problem was present in the OEM firmware it came with as well as your nano and stock ROMs), but no crashes or hang ups.

I still would appreciate if you could re-upload your M8S_PRO+-V0321_TVStock-20170825.zip so I could at least have the most recent V0321 version, seeing as my box won't take any V0691 firmware.

Thanks again!

P.S: Is it possible to use the kernel/system from p212 boxes on p21x boxes like the M8S Pro+? Your Beelink Mini MX3 II TVStock ROM works beatifully (very smooth scrolling) in a p212 box I have, would be great to be able to run that ROM on the M8S Pro+ (don't care about L1 Widevine since I already lost that trying to unbrick the box, and if I have to use a Wifi dongle that would be ok too as the built-in wifi on the M8S Pro+ sucks.)

Check the archives here: http://freaktab.org/27~f

I haven't tried porting any Marshmallow ROMs to the M8S Pro+, but I suppose it's possible in theory. Just swap out the .PARTITION files and image.cfg in one of my M8S Pro+ burn packages with Amlogic's Customization Tool.

[polpus]

Check the archives here: http://freaktab.org/27~f

I did, unfortunately there's only M8S_PRO+-V0321_TVStock-20170825.img, no M8S_PRO+-V0321_TVStock-20170825.zip file

As for flashing a Marshmallow, Amlogic USB Burning Tool always fails at 98% on this box, for all firmwares except for M8S_PRO+-20170829.121614.V0321.img, that's why I'm using modified zip updates.

Then I'm afraid don't have it anymore. It's not in my local archive either. (I keep the .img files, but usually toss the OTA updates.)

That failure at 98% should concern you, since it means it's failing the checksum verification. Switching to an OTA update to skip the write verification may solve your problem in the short term, but the underlying issue isn't going away.

Bummer =( Is there any way to convert the system.PARTITION file in the img file to a system.new.dat + system.transfer.list?

Yeah, I know it's not ideal to flash OTA and skip verification, but so far I haven't encountered any problems so I guess there's very few bad blocks in the system partition.

Did you notice any major improvements when going from V0321 to V0619?

Also, I noticed something really odd: If you open Google Play Store (in TVStock ROM) and scroll down to "Top Paid Apps" and "Top Free Apps" lists, do you see a difference in scrolling smoothness when compared to the other rows? Those two rows that have an additional banner in the background scroll much smoother for me than the other rows.

It's possible, but ask me again via PM in a few days. I'm trying to get updates out for the Beelink GT1, M8S Pro L, and Z69 right now.

Thanks man! Really appreciate it. You have one of the affected boxes as well, right?
