My touchscreen not respond,helppp

Hi , I have a grand problem my display does not respond to my commands, I have the model Huifei s07 , r3188.android 4.4.4 malaySK.video.thanks

does the whole touchscreen not react or does an area (e.g. top left) still work?
Did it work before flashing Malaysk ROM?
Did you also flash a new MCU (just for reference - should not be related though)

I recommend using a keyboard and mouse to go into the settings and re-enable the boot animation (Settings > "System TM" > Prop mods).
Every time I disabled the bootscreen, I lost my touchscreen, steering wheel buttons, and buttons on the unit itself. All other modifications to the build.prop went through just fine, but disabling the boot animation always broke everything.
I'm also on a RK3188 running a Malaysk 4.4.4 ROM.

reviving an old message, do I just need to plug a keyboard and mouse to USB and they will work?

I finally changed the touchscreen.

Firmware Update to Marshmallow - GPS Stopped Working

Hi!
I've made a post in the Asus forum, with no luck and I found this page where you seem more technical :
Two days ago I downloaded the Android MM 6.0 update from the Asus Homepage downloading the version WW-4.21.40.144 , since I live in Brazil and the phone was bought here. I followed all the steps one by one till it got updated.
The problem is, since then my GPS is not working (Waze, Googlemaps ans several apps).
I tryed:
1. Giving all permissions of location to the apps
2. Puting the settings in High Accuracy
3. Restarting the phone several times.
4. Switch on and off Airplane mode and 2G 3G ands 4G (I read sometimes its interference from that)
5. Waiting almost an hour with the phone outside (sunny day) to see if it detects the satellites.
6. Every app inthe appstore that promise GPS Fixing (reseting, A-GPS and all kind of tests. Funny thing, the sensor IS working acording to those apps.
7. Factory Reset
8. Factory Reset and Erase Cache from the bootmenu. (as indicated in the Asus Forum)
9. Downgraded to Lolipop again. WW-52.20.40.196
10. Again every app to reset the GPS.
Nothing worked.
To my surprise, now I have Lolipop and no GPS. So back to basics but, worst.
The Asus forum told me to Update to the latest version, which I did:
1. Updated my phone with the latest MM version. 4.21.40.223.
2. Put the location options in "High Accuracy" and permissions needed for the apps.
3. As the old software was installed after that, I tried Waze. No GPS Signal was found.
4. Did a factory reset.
5. Put the location options in "High Accuracy" and permissions needed for the apps
6. Installed the apps GPS Toolbox and Waze again, the both can't find a GPS signal. I left the phone outside for 10 minutes.
7. Tried to install the version UL-Z00A-WW-2.20.40.198-user by bootloader, but it says it cannot update to an older version, which sounds about right. (I had to try)
What else can I do? I don't mind going back to Lolipop, but when I did GPS didn't work.
Is there any chance the new Update wrote something apart from software in the chipset that cannot be undone?
Help please, I really need the GPS!
Phone not rooted.
Thanks!
Juan

After long hours of searching, reading and trying I got it fix. How?
0. Have a full charged battery or have your phone plugged to the wall (except for the USB stuff on step number 2, obviously)
0.1. Make backups of all the info in the phone, because everything is going to be erased.
1. Download the version WW-52.20.40.196 from Asus website.(unless you need the other like CN, JK, etc, see Asus site to be sure)
2. Copy it to the internal storage of your phone in the root of it (not in any folder), via USB.
3. Get to the boot loader (Turn off phone and once is off, push the power button with the Up volume one until it vibrates 2 times. Release only the power button until the menu appears) - Search the forum for more details.
4. Select "Recovery Boot" with the volume buttons and press the power button to confirm.
The next steps are all in the Recovery Menu (once it finishes every step it goes back to the original menu, no alerts, sounds or nothing. So check every now and then)
5. Make a Wipe/factory reset, and wait, it takes some time. (use the volume buttons and press the power button to confirm)
6. Make a Wipe of the cache. (use the volume buttons and press the power button to confirm)
7. Install update from Internal storage selecting the name of file you copied on step number 2 (use the volume buttons and press the power button to confirm). It will take a while.
8. Reboot the system (use the volume buttons and press the power button to confirm)
It will restart with the phone in the Lolipop version and the GPS working fine. Even after the Lolipop updates.
Marshmallow update has a bug, that at least with my phone the GPS doesn't work. Tried reinstalling marshmallow latest version after the GPS got fix, just to prove the point, and in fact, it stopped working again.
Then I did all the steps above again and went back to normal again.
I STRONGLY RECOMMEND NOT TO UPDATE TO MARSHMALLOW WITH THE ACTUAL FIRMWARE VERSIONS AVAILABLE.

I also had this problem with Marshmallow ROM, as the GPS is not working in terms of unable to locate any signal from satellites.
However, I also solved the problem with a method sounds very silly.
I turn on my GPS overnight using an application called GPS Status.
The night I turn it on, it was locating 0 satellite (it will write 0/0 SAT). However in the morning, I found that the GPS is now working, locking on 8 out of 24 discovered satellite (it wrote 8/24 SAT).
Now my GPS is working seamlessly.

Thanks! I will try it next weekend. I need my phone this week. Hahaha
I ll post when I do so.
Do you know other similar cases of people who did that and worked?
The thing is, now I have Lollipop again an I noticed how slow the system is running with applications. I d love to have the update, but not sacrificing the GPS

I decided I won't make the test because it doesn't justify the risk and time.
I'll wait for a newer update or just stay with Lollipop.
Just to let you guys know in case someone was waiting for this

I downloaded GPS Status as suggested by SleepingAran and ran it once. Now my Waze is working seamlessly. Thanks!

There's another simple solution that works:
Follow exact steps:
1. Turn on location and set high accuracy mode
2. Open google maps
3. Move your phone several times in the shape of 8 (8-10 times should be enough)
4. Close google maps and clear it from recents screen
5. Start google maps again. Profit

[MTCD/E] [PX5] BT Search and connection issues with device name and pin

Recently some users including me are having issues with BT Connection, device search, setting device name and making changes persistent.
BT MODULES THAT IT WAS TEST ON:
SD-968 - [HA] [MCU MTCE 2.75] Firmware 20180201 and few earlier = WORKS
MD725 - [??] [MCU ???] Oreo Firmware = DO NOT WORK (According to feedback) LogCat needed to see if Firmware communicate with BT Module at all.
METHOD 1 (SHORTER):
1. Force Stop BT app
2. Clear DATA and CACHE for BT app
METHOD 2 (LONGER):
Here are the steps I've done to make it work.
1. Boot device (restart if it was not in deep sleep)
2. Directly go to system BT settings (drop notification and tap on BT)
3. Set Device name and PIN
4. Press refresh
5. Go to Home Screen (Home Button)
6. Open BT App -> Configuration
7. Name and PIN should be entered now
8. Disable/enable Auto Connect and exit app
9. reenter app and configuration to enable Auto connect
10. Make sure that all previous BT profiles for HU are deleted on phone and that phone is visible for all devices (usually when BT configuration is open device is visible)
11. Try to search for devices. It should fail (it failed for me)
12. Go to factory settings
13. Change BT Device even it is wrong one (I have SD-968 I changed to MD725)
14. Tap Apply -> Exit -> CANCEL on reboot prompt (without doing step 13 there will be no scheduled restart)
15. Reenter Factory settings and set correct BT Module (I have SET SD-968) Tap Apply -> Exit -> and Confirm REBOOT
16. After Reboot Go to BT App and try to search for phone it should be found (make sure it is visible like in step 10)
17. If all is OK you should see the phone and you should be able to use it normally (it worked for me)
Attached pictures of some steps for METHOD 2.
NOTE: I'm ATM at HA 6.0.1 Firmware from 20180201 and issue happened after upgrade. Also from what I see Users have same issue with and after Oreo update. Hope I helped

Thanks for the info. Have you tried this method also for oreo rom as well ?

A step that worked for me was to clear data and cache for bluetooth app..

Good point it didn't worked for me but, it can also help. Added to main post.

You can trigger a reboot with "hctreboot" in factory settings. Does that work instead of doing steps 12-15?
I definitely have the BT issue. I have an Xtrons(GS) MTCD/E PX5 Oreo and an Xtrons brand OBDII. They won't talk or disconnect. I'll try this tomorrow morn and report back.

I have same GS MTCE 2.75 PX5 OREO but an old OBD2, give HU same password as OBD2 adapter..

Point of 12-15 is that HU re init Module itself along with software. Not sure if it works that way on MTCD/E but usually it works on modular systems.

Tried with PX5 oreo installed with no luck. Both methods are not working for me.

What???(I thought that this was a trick for oreo)
In my unit BT(MD725) works without any tricks for MM.
I tried your trick with 2 kinds of oreoROM(HA and GS) but BT did not work.
Thanks anyway

I'm sorry, but as I wrote I have SD-968 BT module not MD725. I'll update main thread with so far know to work devices.

Any news?

Not that I know, I'll be back from Trip on Sunday, so I hope I'll finally finish the tests and upgrade to Oreo in April.

seems to be the same
The solution is to go back to android 6, the problem is that it is not as fluid in my case as android 8.

Hi, same problem here....
I can not use my ODB2 connector on my Android 8 radio either.
Is there an adapter that works?
Is there a trick to make it work?
Greetings and thank you!!

Hi..any update on how to get the bluetooth working on android 8..

if you still have android 8 installed, try going to factory setting and change the BT Device even it is wrong one (anything other then MD725) tap apply and exit and reboot.
after reboot change the BT device back to the original one (MD725) tap apply and exit and reboot.
after reboot go to the system BT and try to search if the phone name appears let me know.
i still didn't try the above method on android 8, but if anyone with MD725 module is still using android 8 please try and update us.
thanks

Dasaita MMCNP - BT connection problem
Hi, I have Dasaita HA2106-V840-8 a problem with Bluetooth connectivity. First time I managed to connect my phone to Dasaita MMCP (car_kit), but after a few days the devices failed to connect. I guess my device has embedded SD968 BT chip, in accordance with the description.
When I enter the name of the device and new PIN in BT settings, and then turn on finding the device, they are not visible to each other. I tried this other day too, but when I turned MMCP, entered settings was gone (not memorized). No name, no PIN, but also there is no connection. Search doesn't have results. At the end I tried to unpair devices and pair them again, but I get a message on my phone "Unable to communicate with CAR_KIT".
When I entered in settings for BT (settings/car/factory setting/application-choose...) it was set to WQ_BC6. And then I tried to set up SD_BC6, reboot, search BT, nothing was found again. Then I returned to WQ_BC6, reboot, search BT, without success. In the end, I tried to set up SD968, but it's not worth it anyway, MMCP does not see a mobile phone. I also tried several phone models without success. I also went to the BT application and clear data and cache, but always the same thing - BT devices do not see each other. I'm not even sure BT is ON because it doesn't have a special slider to move On/Off.
What should I do? Please help me!

[Request] mcu.cfg file

Hi everyone,
I have a problem with my HU... the knob volume and knob seeking not working in rotation ways. Working only if it's pushed(mute and back). I read almost everything on this forum related with this. Also I already posted the problem here and today I had some time to spent and I tried to solve this issue but without any luck. What I have done? I tried to reset button panel from key study, I tried to reflash with old mcu.img, new mcu.img, patched mcu.img, to flash with an empty mcu.cfg (0bytes), also I've tried with another rom(rooted one) to insert command manually to assign keys code ( am broadcast -a com.microntek.irkeyDown --ei keyCode XXX )... nothing changed.
After all these attempts I came up with an idea, to flash my mcu with a mcu.cfg from you. Maybe will work...
So, here is my requires, to helping me with this cfg file, saved by you from your good working HU. also I'll need mcu.img to flash same versions as your HU on mine. Or at least to tell me your version of mcu and I'll search it.
Now, my HU it's a MTCD MX with physical buttons (for VW car). So I need your exported dmcu.cfg from your mtcd mx HU.
!!!An advice for you, those who want to helping me, Do not ever ever choose "hardware key study" and assign one, just for play or curiosity, if you pushed, just go back. Don't "save and exit"!Because in this way you will lose the settings for all physical buttons... and you have to assign manually, but the knob rotations can't be assigned anymore. Like this I lost the knobs functions. That's it!
Thanks a lot my friends!

Solved
Finally solved! How?!...
In factory settings > other settings > knob mode it was a wrong setup "IO ports". I entered here and I saw there are few types of settings. And because i don't know what they means, I've tested "2 10k/20k ADC" and BINGO...both knobs works again.
Most likely was my fault for that wrong setup from knob mode... I don't remember when I've changed but doesn't matter now... new setup solve my issue!

Hi There, I'm about to update my HU and wanted to know how to export my current settings. Is there an APP you install?

Never mind I found it in the car setting under "Factory Settings" my password was m123456, I'm running a MTCE_HT. I've seen where another password could be 212121.

[PX5] MTCE Android 9 Bluetooth and volume issues

Hello all,
After finally updating my PX5 to the latest MCU and firmware (according to Hall9k) using his mod application, I am now experiencing low volume on everything (radio on max is pretty low volume when you're on the highway) and bluetooth settings always reset to empty settings and will not find my phone and my phone will not find the PX5.
I've tried resetting wifi and bluetooth settings, no luck. I've tried resetting the unit back to factory settings, erasing all data, no luck. I found a post regarding the bt issue and followed all his steps (changing the bt device and reverting back to it, etc.) but no luck. I found a post which said the device somehow needed to be an other one than previously set, so I've tried all the devices in the list, but no luck. Only at the parrot device, the bt settings were automatically reverted back to factory default (Car... something), but it wouldn't connect. Normally my device was on SD-968 I believe (not currently in my car).
So, that's my main issue now. How can I get BT to connect, without rolling back to Android 6.0.1? Because on 6 it worked.
And second, how can I get the volume louder? Again, after updating the volume somehow seems limited.
I don't want to go back to 6, if there's an other way, because 6 had its own problems...
I'm really lost here and have spend many hours in the car, trying everything I could find online (even manually clearing cash and storage of the bt settings, etc). There must be a way this should be fixed.
My Android 9 fw is from November (Hal9k send that one to me)
My MCU is MTCE_GS_V3.17bd_3
