[ROM] Mecool M8S Pro Stock & Nano Nexus ROMs (Android 7.1)

[ClarkKent]

Once in TWRP, prefix file name is of lesser importance.
Copying of log data will show what happens just prior to the e7
Probably the roms target device is a mismatched name, as compared to your actual box's identity.
Compare the two... Open the zip in its own folder, open meta down thru android. Once at updater script, that will open in a script editor for matching the two targets.
Once done, reZip and move back to 1st level of sd.
It should go by reset recovery or ota via twrp in either case. METHOD 1: UPDATER SCRIPT HACK TO FIX ERROR 7

Note: Use this method only when you’re 100% sure that the ROM you’ve downloaded is for your device. What this does is to bypass assert checks in recovery so that you can install the ROM without any checks.

1. Open the Lineage OS ROM zip using any archiving software like 7zip, WinRAR, etc… You can also open it on your device.
2. Now, you need to navigate to this path: META-INF » com » google » android » updater-script.
3. Open the file updater-script in a text editor. You’ll see a bunch of lines with the command assert and the model name of the device next to it.
   
4. If there’s a mismatch with the codename of the device in the script, you’ll get Error 7 while flashing.
5. So, just either edit the code to match your device’s codename or delete all the lines having the code “assert & getprop”
6. Save the file.
7. Try to install the ROM now.

Thank you
I've downloaded the OTA version and saved it in ext. sd card, then rebooted into twrp and tried to flash but found an error and stopped.
Should i write the OTA rom in internal folder? Or maybe download it again?


Could be corrupted dl, it's happened before. If twrp can find it. It's always flashed is my experience.
What's the error? Are you copying log to SD card, for future scrutiny? That helps.
Might want to get with the boss... @ magendanz. Yaknow?

Since its on the 1st level of card already (no subfolder), you could try reset button method. Capture your twrp log though.

I downloaded again, saved in internal download folder but again failed. It says "error 7"
i think, possibly something happened with the zip file. It is not right. If possible , magendaz, fix it and uploaded again.

P.s if i try reset button method, should i rename it into "update.zip" ?

I've flashed past roms residing in the internal downloads folder, via twrp.. Data intact just fine.
Suggest you bkup data and basic dalvik/ cache wipe
Provided your upgrading from Mag's last Pro rom. Some others require data / factory wipe... Pretty sure

The OTA update can be done with the sd card method or another way?
i assume, we dont need to setup the box from the begging, right?

As promised, here's a build of the Nano Nexus ROM for M8S PRO based on the Shiningworth firmware. Basically, it's the same as the ones I created for the Vorke Z6 and Beelink GT1, but I've updated the device tree so that Ethernet now works correctly.

Burn Package: Nexus_M8S_Nano_NHG47L-20180119.img

This has a bunch of new features and fixes that we haven't seen yet from VideoStrong. For starters,

- Quick (2-3 sec) resume from sleep with preserved user state
- Auto framerate settings (3 modes)
- Superuser root setting
- Drag up from bottom of screen to show navigation bar
- HDR and SDR settings
- Additional Dolby/DTS/Digital audio settings

If the consensus is that this is better than the ones based on the official OEM stock firmware from Videostrong, we may move to this new foundation permanently. For now, though, it's just a trial. What do you think?

Hi Magendanz,
Will you be doing Magendanz ShiningPath test for the Pro L ?
Seems like it may be an upgrade there too, if you have any time or inclination !
Thx.

[ClarkKent]

I'm a player, when and if you're able to get an ota up.
Danke

Yes, Ethernet seems solid. I haven't noticed any problems there.

I don't think any app is going to help that animation stutter issue, as that's probably happening at the kernel level.

[ClarkKent]

Most interesting. Thanks for the update.
Bt is no issue, as rarely used recently. Ethernet is, I understand that is solid?

Can sw interface be supplemented or assisted by an external app? Ie: terrarium tv offers a backup decoder if performance requires.?
Stutter during transition looks like what?

... And yes, when you can a sd/ota version is appreciated and more conveniently useful.

As long as you flash with the USB Burning Tool defaults, your Widevine L1 keys are safe. As for an OTA update (.zip file), I can do that pretty quickly if there's need.

Remember, we've still got the Bluetooth audio stuttering bug to deal with on the Shiningworth firmware. With tillaz87 joining the effort now, I think we're close to a fix, but the SW user interface also isn't quite as smooth as VideoStrong's. (You'll see stutters in animation and transitions, but playback seems unaffected. It's pretty subtle, but it seems that they've got a kernel module that isn't yielding the CPU when it should. I'll need a better Android profiler to know more.)

Magendanz sorry bro, but we can not DO IT - if we take it to our kids, they will kill us

Sounds greatly improved. I'd like to try.
Can you, will you be able to release a SD version?
Will this be compatible with the WV update from GB we've discussed recently.

mXHX, if you feel so strongly about live wallpapers, you need to create your own custom ROM. With support pulled from the latest Amlogic SDK, that's going to be a heavy lift and you're one of only two people who seem to have missed it. Frankly, it's just not a priority for me.

Nice work! So during the consensus:
- no more live wallpapers
- no native AC3 audio decoding with amplayer
- but working wake up sleep... It will be a little longer consideration

......maybe at final end of the ages the best version will based on ugoos am3 (same wifi/bt as M8S PRO) with their fine tunned audio/video decoding, native fileserver, root/unroot/supersu-root, native hardware monitor, usefriendly logcat support with IR codes dumping, etc.etc.etc. but I don't know what does it all matter you to build on it.
