I need help

I recently bought Android HU for my mercedes E 2005 form Isudar China.

Android 8.0 Octa core 4gb Ram and 32GB rom with DSP.

After finishing installing it. I tried to turn on the WiFi but there was no way to turn it at all (it stay in off side). I also notice that the MAC address for the WiFi is 02:00:00:00:00:00 , which I think it is wrong. In the other hand the Bluetooth is working but i couldn’t use it for Internet (it work only for calling and music play) and I can’t send or receive any file using Bluetooth. I bought TB-link WiFi dongle but didn’t work I also tried to use 3G dongle, it also didn’t work. When I connected other device to USB (DAB) it works. I asked the seller what to do?! He didn’t give me answer. I need professional help. I don’t know if the problem is hardware or software. Because the device is totally new, and from beginning doesn’t work.. Every help is appreciated.

Install Original Android PX Unit operating system from USB Stick (take about 1 Gt from USB stick) and choose option that erase all data from PX device.

You find operating system from this forum (xda-developers.com/android-auto/).

Normal network or system reset, or forced system restart (change something in Settings > CAR > Factory settings) not work. Also MCU update dont work to this problem.

I can't turn on wifi.. and usb hub stop working..

This problem happened after restart factory

Please help me

Sorry - no help from me, but I've got the same problem.

Got a new erisin ES8985V with PX5 32GB/4GB and android 9.0 yesterday. It worked with wifi and usb-dab+ box for one hour. Then after rebooting, the dab+ couldn't connect any more. I made a factory reset and since then no wifi and no usb.. MAC is 02:00:00 ....

MCU is MTCE_YB_V3.41_1

Unfortunalty the seller (erisin.com) doesn't react.

Thanks for an advice.

I have the same problem, Bluetooth works but not wifi. Did you find a solution? :(

...Hardware issue. Return for warranty service.

---------- Post added at 03:15 PM ---------- Previous post was at 03:14 PM ----------

Read the posts here, would that help? Or return under warranty/buy new unit.
[MTCD Software Development] Gnomepises:
My HU has more than 2 years, it doesn't have warranty.

In other hand I've seen that is possible to fix it with a wifi usb stick. https://www.youtube.com/watch?v=pkefBbLTPuQ

Have someone tried that? I think it probably is the faster and cheaper way to fix the problem. And for me is not a problem to use one usb for wifi. This things are useless without internet connection.
[MTCD Software Development] teddyking:
TP-link TL-WN725 wifi dongle is working for me. I can buy it for USD6 here, so i tried with my Dasaita PX5 HU.

Onboard wifi on the HU is sometimes works and sometimes stops. I found that it is RTL8188 chipset. I tried reset USB host with tasker method but it is still not working. During the time that it isn't working, i found that others USB port is function properly. Therefore, i think the onboard wifi module is broken.

TP-link TL-WN725 is also RTL8188 chipset, so android system will use it as wifi adapter for the HU. But the problem is when the onboard wifi is just working at the same time, wifi connection won't work. If you can modify android ROM to have driver for usb wifi dongle with specific chipset, then it should also work.

I'm thinking about desolder onboard wifi module and using usb wifi dongle permanently. But some users reported wifi problem after desoldering so i'm still thinking about this method.
[MTCD Software Development] Gnomepises:
I've bought the same wifi usb stick but it doesn't work for me.

How can I know wich chipset is my wifi module?

Or How can I know the usb that fits with my HU?
[MTCD Software Development] Gnomepises:
First thing i tried with some USB Sticks but Wifi didn't turn on with Original ROM or Malaysk Rom 8.0

<<<<SOLVED FOR MY HU WITH MALAYSK OREO 8.0 and this wifi Stick>>>>>

My HU unit is XTRONS PE9846BPL https://e3io.com/pe9846bpl

My wifi module in my px5 was not working weeks ago. I think it's already broken. I've tried to install several firmwares without any positive result. I couldn't turn on the wifi. BUT...

I can confirm this stick Comfast wu725b https://www.aliexpress.com/item/32852230418.html

Is compatible with my unit and with Malaysk 8.0 Rom. This Wifi stick has solved my problems. It has been 3 months without wifi. The easiest and cheapest way to fix my problem.

After the stick was arrived, I've only plugged the usb and a reboot to the HU... the wifi was already turned on. Awesome! ;D
[MTCD Software Development] Manuele83:
I have same problem but it started right after a firmware update, so it cannot be hardware...must be software 100%

wifi hardware issue and fix

I had a similar issue with my XTRONS TE103AP, about 2 years old. It was running well, 3 month ago I installed HAL9k v4.0 and everything went fine. Then, suddenly 2 weeks ago during holiday I could not activate WIFI anymore.

All trials with reset to factory, latest MCU or XTRONS firmware could not help. I dissambled the device and started some tests. The wifi module is soldered on the back side of the main board. It is a REALTEK RTL8188ETV which needs 3.3V operating voltage.

https://xdaforums.com/picture.php?albumid=16351&pictureid=60707

But I could not measure any voltage when I switched on the TE103AP. Voltage is generated by 3.3 regulator AZ1117CH-3.3 but which was no powered too.

I noticed that the power regulator is controlled by software via an output pin of the PX5 board. There is a inverting switch with two transistors between PX5 output and regulator IN.

https://xdaforums.com/picture.php?albumid=16349&pictureid=60705

https://xdaforums.com/picture.php?albumid=16349&pictureid=60703

The dimensioning at the base connection of the NPN transistor is strange. I would have expected that resistor R62 is smaller than the bias resistor R80. But dimensioning is opposite and hence even if output of PX5 is 3.3V, base voltage is too low to drive the NPN transitor.

Since I did not have the right equipment to switch the tiny resistors I just connected 5V directly to the input of the regulator:

https://xdaforums.com/picture.php?albumid=16349&pictureid=60701

Wifi did not work immediately because I assume that there is no correct installation of wifi drivers when module is dead during firmware update.

But after a new firmware update with this fix wifi worked again :)

My Conclusion:

I guess that wifi worked initially just borderline / by chance because of the strange dimensioning at the NPN transistor.

After some aging of the transitors the powering of the wifi module was gone.

Since my device was older than two years (and did not have the original firmware) I repaired myself.

But if you face this issue on a newer device and resetting to factory does not help, I would recommend to claim this to the manufacturer.

Regards

Matthias

I have the same problem with a PX6 Dasaita with a Hal9k rom after resetting the rom.

I tried MCU updates 3.40 > 3.57 > 3.60 > 3.62 > 3.71d and re-installed the Hal9k rom (Hal9k_Mod_4.0_MTCD_MTCE_PX6) without success.

edit : idem with stock rom PX6 HA2_rk3399_9.0_ota(20200521)

edit : ps, i see errors in the log of recovery.
[MTCD Software Development] berlo:
After doing the MCU and system updates, I realized that by unplugging the dual usb connector the wifi comes back !
[MTCD Software Development] sarruman1:
Hi,

Did you, by any chance, find any solution to your problem? Seems that I'm facing the same issue, very frustrating indeed!

Thank you in advance!
[MTCD Software Development] berlo:
No, I haven't found a solution.

I don't plug in the dual usb connector
[MTCD Software Development] skezza:
I believe I may have a similar issue. I've lost my dual USB ports. I think I've fried a component and whatever was supplying 5v to that has stopped.

I can make the ports work if I run 5v to the usb devices via a Y cable. This would be fine but for some reason, coming out of auto sleep causes the device to enter some sort of meltdown mode which eventually results in a hard reset. One of the visible defects is no Wi-Fi although it just gets worse until it dies.

My plan is to disassemble the device and try to work out what component is dead but who knows if I'll spot it. Sometimes you can't see it :(

[Amazfit] D_L_I:
Hello,

I have the amazfit stratos for few wkks now and in the last 2 day it started to act quite weird.

Out of the blue it starts an activity without touhcing it, it is scrolling through the options rapidly and erractically. all without interacting with it whatsoever (even when the watch is not on my wrist).

I tried to do factory reset twice (once with restoring data and once without) and it did not help and the issue presist.

is there something that I can do to fix it?
[Amazfit] lfom:
Bad digitizer. Clean it well with a soft dry fabric, restart watch and reset data as last resort: unpair, pair again but do NOT restore old data to watch. If it's not fixed after that, it's a hardware issue.
[Amazfit] D_L_I:
What is digitizer?
[Amazfit] lfom:
AKA Touchscreen.
[Amazfit] 96degrees:
been there..my stratos acted out like yours too..factory reset or unpair or pairing again to different phones not helping..

so i returned it to the seller and 3 days later i got a new one..

Hi All,

I had a previously rooted 8142, but it crapped out on me last week, so I've just bought a new one. I'm trying to root it now. I've unlocked bootloader, and installed the TWRP app, but I can't figure out how to root it.

I was running windows and used Xperifix when I did my last one, but now I'm using Ubuntu, and there's not really any software (like Xperifix or One Click Root) available.

I've been using FlashTool, and can get it to show root privelages, but I have no idea how to flash a recovery image using it.

I tried using Platform Tools via the terminal and I think I was able to flash a TWRP recovery image to the device, but the TWRP app isn't seeing it, nor can I boot into recovery mode.

I tried to download a recovery image via the TWRP app, but even when it's downloaded, the TWRP app isn't finding any recovery images despite pointing the app to my downloads folder.

TWRP is also showing "No Root Permissions"

I can't flash SuperSu or any other ROM's without being able to boot into TWRP recovery menu.

Maybe I'll have to install windows to use the rooting software. Does anyone have any ideas? Been messing around with it 6 hours now and still can't boot into recovery. :(

Thanks for any ideas.
[Sony Xperia XZ Premium Questions & Answers] ricardo99831390:
first I dont know if youre using fastboot so do "sudo apt install android-tools-adb android-tools-fastboot" then open a terminal were twrp is located and type fastboot flash recovery "name of twrp".img and then you are ready to go. I dont know if you can use this phone without a specific driver so that can be a problem. If you cant do it that way i recommend you using a virtual machine with windows and run fastboot (platform tools trough there) so you dont have to remove ubuntu.

Also remember how to access fastboot
[Sony Xperia XZ Premium Questions & Answers] tombow:
Thanks! I'll try both of those methods over the weekend and report back.
[Sony Xperia XZ Premium Questions & Answers] ricardo99831390:
well i forgot to mention, the fastboot flash recovery command depends on your android version so take that in count.

[Samsung Galaxy Tab S3 Questions & Answers] joberg3000:
How I bricked (and unbricked) my tablet SM-T820 due to OEM Unlock setting and battery drain - I hope this is useful for someone making the same mistake! I successfully rooted my Tablet S3 T820 with TWRP 3.2.1-1 and Magisk and installed SM-T820 Tweaked without any problem the moment I received it - it's a great daily driver!

While fiddling to fix an app crashing due to safetynet issues, I unchecked OEM-Unlock and forgot about it. The tablet ran out of power and upon reboot gave an FRP boot error "Security Error: This device has been flashed with unauthorized software & is locked. Call your mobile operator for additional support...". Any attempt at booting into TWRP was FRP blocked I guess because of the locked Bootloader. I immediately tried doing a stock firmware restore etc. via ODIN which failed at about 65%, probably due to a low battery (which I didn't know as there was no way of seeing the battery status). Upon reboot I had a screen saying "use the emergency recovery function in the smart switch PC software". When I tried reflashing stock firmware through Odin again, the tablet connection kept disconnecting/dropping out every 10 seconds or so and restarting always going back to the same “use smart switch” error message. The same happened in Download mode. I now know this was due to a drained battery. I couldn't power off the Tablet in order for it to charge as it always switched on as soon as power was connected.

The fix: I noticed when in the error boot screen "use smart switch to recover" it didn’t charge at all (I had it plugged in for 8 hours) and always cut out and rebooted to error msg. every 10 seconds. The first time I managed to stop it cutting out was by booting into Stock Recovery Mode with "Home & Vol+ & Power" buttons while plugged into the wall socket (stock recovery must have installed just before Odin failed the first time I tried to unbrick). I had it plugged into the wall socket in Recovery Mode for about 2 hours where it very slowly charged a tiny bit. In stock recovery I booted into "Reboot Bootloader" where it went directly to Odin Mode saying “Downloading... Do not turn off target”. I then reflashed my firmware without any errors. After first boot the battery was still only on 1%! I again have a brand new, functional Tablet! Now back to Rooting . . . and never touching oem-unlock again! :p

Hi guys, I'm new using Samsung phone.:D Is there any way to lock the screen without press power button? I saw an app called "Good lock" but it's server down:confused:
[Samsung Galaxy Note 9 Questions & Answers] grtmoby:
You can use Soft Lock Screen from the store
[Samsung Galaxy Note 9 Questions & Answers] willcor:
Firstly,

it depends what "Samsung phone" you got.. a Note 9 or what?

Secondly,

as far as i know ? ,

if you use a 3rd party lockscreen app, you canot use Fingerprint etc to lock/ unlock and certain other apps eg like some banking apps.

You have to use a stock (Samsung) method.

Good lock 2018, is only available to certain markets,

worldwide.

I do not have option to install Good lock 2018.

I have installed standalone, NavStar app (Samsung)

(ApkMirror website)

which i believe is part of Good lock 2018.

It has navbar lockscreen option.

Works fine, no issues.

I'm sure there is other Samsung options also. eg Edge panels etc.

Then you are in same boat as me.

I couldn't install Good lock 2018 directly, due to market restrains, etc.

I had to separately in install each standalone app

that's included in Good Lock 2018.

I downloaded these standalone apks.

from ApkMirror website, also i had to download

Activity Manager (free) from Google Play .

It's an app to create shortcuts, to enable you to access each standalone app settings, as it the apps

won't appear in app drawer.

I approached Huawei Service center here and they quoted me for SGD $350 (about US$250) including parts and labour. That was even more expensive than iPhone X screen repair!!!!!!! I tried to find parts on my own but even on Aliexpress.com, P20 Pro screen is sold like $250 SGD. Is there any online stores that could get the screen with more reasonable price????
