X98_PRO_android_5.1_mirek190_v6.0 rom

[metha]

first, thank you for your support.

it wasnt a problem with the rom. i bought it from another guy who doesnt unlocked the oem, so i needed his account from googl to log in also after a hard reset.

s in case, if you sale anzthing with android 5 or higher, unlock your device and cut it from your google account 🙂

cheers metha

Thanks for your efforts

So two possibilities:

1. crashes are related to the GPU.  The some possibilities
   1. Some default settings have been changed regarding the GPU in this ROM in the prob.build
   2. The 4Gb RAM does interfere with the GPU (since the RAM is shared with the GPU) and the GPU needs another settings not to crash.
   3. In either cases, Chrome uses GPU acceleration. Could you try to disable as much acceleration as possible from within Chrome ?
2.  networking. That would be bad. Did you you Chrome without accessing the network during your off-line period ?

What are the changes in the prop.build file between the various roms ?

Intento instalar second install_it (Intel ADB drivers) en Windows 10 pero da un error por ser de un editor desconocido. He reiniciado W10 para no secesitar que los controladores estén firmados pero sigue sin poder instalarse.

¿Alguna sugerencia?

Hi all,

I am new to the forum. I recently ordered the Teclast X98 Pro and I want to flash it with Mirek190 V6 rom. I downloaded all four files I found in the relative post (the flasher, the stock rom and the V5 and V6 roms) and I wanted to ask the exact installation procedure (I’m a newbie).

Do I directly install the V.6 rom ? Does the V.6 include ALL the previous updates or do I need to install the four files in some kind of a particular order?

I would greatly appreciate if someone could guide me through this procedure. Thanks in advance!

[Iñigo Martinez Lasala]

Install only V6.  Clean install option.

Previously you should have installed Windows drivers in order to install new ROM. Follow the guide in first post.

Hi.

Build.prop between versions are almost equal. This is not the problem.

Diffs between both versions:

• At /system/codec, hotplug script. Useless. You can remove it.
• At /system/codec, gov script. Minor changes. Seed parameters are useless but could affect for some hungs. Removed.
• At /system/codec, surfaceflinger script. Useless. You can remove it.

It’s importan to disable forced GPU acceleration for 2D at System/Developer options. It clearly affects stabilty and do not provide any benefit.

Other changes: removed memory=2048M at kernel boot options. This enable more than 2GB RAM memory and for me is a must.

Now I’m testing with other kernel parameters for i915 kernel module (GPU) like i915.semaphores=1 and others. It takes time to test because hangs are not so frequently as in the past.

I think there are at least to type of problems and by removing some parameters and forced GPU acceleration I’ve solved or mitigated one of them because previosly I suffered hangs once or twice a day and now only each five to ten days. During my vacation period I didn’t use Chrome….

But definitively it’s mainly a GPU problem, not Wifi, I think.

Thank you so much

What I've used and what I've got:
TECLAST X98 AIR 3G, TECLAST X98 AIR II, TECLAST X98 PRO,CHUWI HI8, CHUWI HI12, CUBE I9

Could it be related to the known SoC bug that is solved with intel_idle.max_cstate=1 ? On a Bay Trail mini PC, this is required, otherwise random hangs occur at a low frequency. There are bug reports that Cherry Trail SoCs suffer from the same problem.

[dan grab]

any news about v7.0 ? still developping ?

What do you use to shutdown the cores for power saving?

A new ROM would be great. The tablet with V6 gives to much crashes. Me wife won’t even use it anymore.

Reflashing it to V3 results in a frozen tablet with chinese teclast logo on the screen. Reflashing to V6 works, but that doesn’t solve the crashes.

Wat about the new release of Mirek he would try to post ‘this week’ 3 months ago? Is he still alive?

Cheers. Henkie

Yes, that is another posibility. Also i915 rc6 state (for GPU sleep). This weekend I will test with both changes.
The bug you are talking about appeared with kernels 3.1X series and was fixed in 4.XX… but if we limit Cstate to 1 I’m not sure if the tablet will enter into deep sleep.

This bug was introduced in the 3.16 kernel and is still present in the 4.x series (in my experience). Only a few 4.0.x or 4.1.x kernels seem to work fine (see comment 49 of https://bugzilla.kernel.org/show_bug.cgi?id=109051)

Have the kernel arguments changed between v3 and v6? Has the kernel version changed?

There is another annoying bug: for me the sound of a video (or anything really) stops after a short while, which is related to the headphones symbol appearing in the notification bar. Any fix for that ?

Hello!
I need to port Mirek190 V4.0 ROM.
Please give a link to v4.0.    V5.0 and V6.0 can not, they are 64 bit.
I need 32 bit Rom V4.0, for porting to X80 Power.

Hello. I just bought this tablet used and it already has mirek190_v2 installed with Kernel 3.14.37. I needed this tablet specifically for the HDMI out. It does not work. It says it is connected when I connect to any device but there is only blue screen on the other end. Anyone else have HDMI out issues? Yes, I cut back the plastic on the HDMI cable and tried a few different HDMI cable. Even went to the store and tried a few different cables. No luck.

Does this firmare not support HDMI? Do I need to flash to original firmware? Thanks.

[Ruto Inor]

Two pieces of good news.

v6 is indeed very stable once the files in codec directory have been removed. I only got hangs when the screen was rotating, once every 2 weeks.

Now, the problem with spurious detection of headphones seems to be solved with an app called headset toggle, which forces the sound output to your chosen destination.
