[MTCD  Android Head Units Q&A] tsaxman:
I have this unit for ~3yrs and it's been solid until recently. First the music microSD card became unrecognized at times, then more frequently, to eventually disappear completely. Replaced the card to several brands/sizes/formats/etc to no avail.

Only way I could listen to MP3s was to connect an old 4GB thumb drive to the USB port. Again, Tried several newer brands/sizes/formats/etc to no avail. I simply hated to have this ugly thing sticking out on the dashboard, but it was a workaround.

In the last few days the unit seems to struggle to boot (when I start the truck) and the MP3 thumb drive is not longer accessible. And the GPS microSD is not accessible either. Removing the GPS microSD sometimes speed things up and the thumb drive becomes accessible, but that's a hit or miss.

As troubleshooting goes, I've already 'Factory reset' the unit several times, replaced the cards, etc.. to no avail., and although I'm thinking this may be a mechanical issue with the card readers, it's unlikely to be affecting all 3 card readers (USB, Music, and GPS).

I'm thiking the next step is to replace/reinstall the ROM (or a venture into a new one, like https://xdaforums.com/android-auto/...rom-hal9k-mod-2-mtcd-mtce-head-units-t3741583).

Any recommendations are appreciated.

Nowadays, the mobile phone and us are inseparable. It can be said that wherever people go, where the mobile phone is brought, even the toilet is not missed.

The thing that could have been done in 3 minutes, since the smartphone was added, the time has been extended to 30 minutes or even longer.

So, before the popularity of smartphones, what are you doing when you go to the toilet?

https://mega.nz/#!zxInmY6K!iez4Y2Kmg5smCndC8gMqZrjw42FXYVR6CDMM49HCcHQ

This is a dload firmware which works on every DUK-L09C432 with EMUI9.0.

Simply put the dload folder in the root of your microsd, power off the phone and boot it again with all 3 buttons (vol+/- and pwr) pressed for 5-8s.

Voila, it should start installing the new firmware.

[Honor 8 Pro  Guides, News, & Discussion] simika:
quite strange.. since i'm on Android 9 i can't enter fastboot mode anymore!(smartphone is fully working.. rooted , unlocked )

i tried trough adb "adb reboot fastboot "

also by button sequence..

honor 8 pro just restart ...

anything i could do?

P.S. just tried... even recovery is not working!! so i can just use ADB commands but can't boot in recovery or fastboot
[Honor 8 Pro  Guides, News, & Discussion] OldDroid:
connect the phone to pc, keep vol- pressed directly after pressing restart on the phone, it should enter fastboot now.

"adb reboot recovery" should work though.

[Honor 8 Pro  Guides, News, & Discussion] simika:
thank you, I'm gonna try tonight ...

I'm afraid that recovery somehow "disappeared" lol.. when I update from oreo to pie and I changed it to twrp to install magisk! anyway tonight I try, if I get in fast boot I can install recovery (this time pie stick recovery, so I can update to 9.1..cuase if I try "dload" now it just reboot..)
[Honor 8 Pro  Guides, News, & Discussion] simika:
YES ! like that it worked !!! thank you

[EDIT]

so what i want to do is:

fastboot boot recovery.img BUT is not rebooting in recovery( and not loading it )

but it gives me this error: downloading "boot.img" so it's ignoring my command of booting with recovery.img

i've got stock recovery from UPDATE.app file of my actual rom ( 9.0.1.175 )

i didn't want to "install" the recovery cause i'm not sure it's the right file ... : (i've choosen recovery_ramdis.img)

[IMG="which recovery?"]http://www.simiweb.net/recovery2.jpg[/IMG]

is that the right one? in that case i can just install it .. cvause at the moment i can't reboot in any recovery !

[EDIT SOLUTION]

so since anyone could have my doubts ... here it is my " solution !

at the end i did install stock recovery ( which was RECOVERY_RAMDIS.img got from update.app and extracted by huawei update extractor)

fastboot flash recovery_ramdisk recovery_ramdis.img

than i use

fastboot reboot

and since i had the installation package already in my smartphone it went directly into UPDATING status ( through emui update program )

took less than 5 minutes to update to this latest EMUI 9.1.0.210

and 2/ 3 minutes for honor 8 pro to reboot.. and i had to change my underwear LOL !

at the moment i've lost root ... but probably i can get it back in the same way as i did with previous PIE !
[Honor 8 Pro  Guides, News, & Discussion] simika:

Issue solved by Nokia/Hmd together with Mediamarkt Sweden with above and beyond kind of service,

They handled the issue quick and effective without any pressure from social media or newspapers. Kept me up to date with any type of progress in the matter.

And even let me replace the phone with another brands phone due to certain reasons, they also provided for extra accessories to the replacement phone even though it was another brand as well as putting out extra credit at the store of my choice for future purchases.

So my hat comes of for them for the 11 star of 5 stars maximum service

got real issue on my phone night between 23/24 july wich resulted in me and my girl waking up and in less then 1 min the appartement was smokefilled and the phone was like a blowtorchand we managed to toss it from a 3 floor window onto the street wbelow.

we ggot lucky that we ive in a small 1 bedroom appartment with a working smoke alarm just few meters away in the same room .

the phone is now seng in to nokia/hmd EU service center for inspectionon what went wrongwith the device.

and even though this happend i cant wait to get a replacement/new nokia 7plus since i realy loved the model.

hope they find anything fast if there is something wrong with it since the model in my eyes still is a greatphone

atm the phone is on the way to nokia/hmd main service in EU since they where extremly eager to check it out on what may have gone wrong and they helpedme to get a basic timeline by lots of questions so to see if there was any strange behaviour with the phone prior to the event

and as i understood this was basicaly a first for themwith this kind of event specially since it wasnt plugged in atm of the explosion . so i am waiting on reply from them for reciving and first checkup on the device.

[Nokia 7 Plus Questions & Answers] Akibalo:
still no news from nokia/hmd other then they are putting everything under a microscope to try and find anything that might have gone wrong.
[Nokia 7 Plus Questions & Answers] Akibalo:
So update on this issue.

So far they couldn’t find anything wrong in design of the phone and or battery so it looks like it was just one of them crazy bad luck happening.

They still haven’t completely checked everything as I understood but they felt satisfied to close the matter on mud end and do more testing without me having to wait for all answers.

And the solution on the matter for me as I got. New phone and accessories like SD cards, cases, Custom screen covers, wireless headphones as well as a bunch of extra store credit for future purchases.

However due to demands from girlfriend that the same model of phone was not allowed inside ever again if I wanted to sleep in the same bed/apartment ever again I had to pick another model.

However since they didn’t have any similar phone model.

They came up with the suggestion of me picking from any brand of phone even from their competitors. So now I have bramd of phone and really happy with the solution in the end..

So to all that might be worried about this repeating itself don’t be.

Also even hat it took some time I am extremely happy with the solution in this matter as well as they will update me with any future findings in this matter.

Best service i ever experienced in a cellphone warranty issue.

Nokia/hmd gets 11 out of 10 stars for their handeling of the service around this issue.

I took a samsung A40 instead due to the fact that it was good enough for my current needs but I do miss my Nokia. But as My girlfriend Put in her veto against the Nokia 7plus model I didn’t have much choice.

Nokia’s work in the matter is the best I ever encountered when it comes to Customer service and I feel they took it extremely serious to find a solution on the matter and as I understood it was just a one time happening.

But I am happy with the new phone since it is quick software and takes decent photos, but I am going to miss the Nokia.

So I've been trying to revive my 838pro for a few weeks now, It's got the NO GSM, boots to OS fine issue which seems to plague many people.

I'm just wondering how many of you out there have the same or similar (GSM/Radio ceased functioning) problem, I know it's lots but I've made a poll here so we can tabulate some figures. Surely if it's a large enough problem we can do something about it legally? Or at least get some assistance/guidance from HTC?

I know alot of people have been spending alot of their spare time on this and I'm not trying to belittle or disregard your threads by starting a new one, but this is really the thread for people who have tried EVERYTHING! (I even dissassembled the unit, desoldered the backup battery and soaked it in some soapy water for awhile!)

So, if you've tried all the radio upgrades/downgrades, hardware/software/voodoo tricks and still come up with zilch, vote yes.

[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] Jorge Humberto:
Hi,

The battery of my Samsung Galaxy Note 8.0 GT-n5110 was lasting under an hour and I decided to replace the battery. I bought a brand new one (from 2017) and replaced the old battery (from 2013). Since then, the tablet stopped charging at all. Before, apart from the short battery, tablet was working fine.

Some symptoms:

1) The new battery showed at 66% charge and ran for a couple of hours and then the screen started flashing and tablet switched off.

2) The old battery showed charging at ~70%, but would die after a few minutes;

3) both batteries now show as charging when plugged in and go to maximum 3-4%;

4) when plugged in, I am able to go into download mode and TWRP and keep there "forever";

5) when I disconnect the charging cable, the screen flickers a bit and tablet switches off;

6) I've tested with different cables and chargers that work on other devices;

7) I've replaced the charging port, no change;

8) in TWRP, tablet states that "/data" cannot be mounted

9) I tried once to boot into the system while plugged in and it started booting, but hit a brick wall when it gave an error message about the data (OS? can't remember) being corrupted and needing to factory reset the device.

Tablet is rooted and has LineageOS 14.1 installed on it.

Any ideas? I've read somewhere that it might not charge due to a corrupted kernel, and might need to install a new rom, but would prefer to do this with a charged battery...

Cheers

Jorge

UPDATE - 2019-07-30

if I let it charge while in download mode, it does charge, but very slowly - e.g. 24% in 3h for the new battery

UPDATE - 2019-07-31

Finally managed to get the battery charged to 100%, but in download mode. Will try to re-flash the firmware on the tablet to see if that fixes the issue.

UPDATE - 2019-08-02

OK, flashed a new ROM on it (LineageOS 14.1) and still have the same issue: It charges (slowly) in download mode, but that's it.

[Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti] ektus:
If you can get into the system, can you check the reported battery voltage? e.g. using "GSam Battery Monitor" or "Ampere".

I've replaced the battery twice on my main tablet and once on the spare and haven't had that kind of problem. The old battery on the spare was charging very slowly, but other than that was working normally and still had approx. 15Wh capacity.

With my main tablet and new battery, at 90% state of charge the voltage reads 3.974V and drops to 3.3V when the tablet forces shutdown at 18% or the like. I'm trying to lower that threshold in order to better match the SOC and the real shutdown point, but haven't run the battery dry yet after inserting the property in buil.prop.

Hi All,

I have a 10.1" Android Head Unit and it has two wires for steering wheel control. I thought this unit had CAN or CANBUS capabilities but its Key 1 / Key 2 for the steering wheel controls.

How do other units interface the CAN BUS?

What hardware do they use?

Is it standard SLCAN (can over serial) or native can0?

Does can-utils work on other units?

I'm looking at adding the hardware myself if it uses some kind of common hardware.

My car (Mazda 3) and a friends (Volvo XC90) have the steering wheel controls on the CAN bus.

My plan was to code together a canbus to SWC but if I can get native CAN on the device that would be great.

I2C, SPI, USB, Serial... do we know anything about the chips used for decoding the CAN?

I'd really like something and I will do hardware and program code as long as it's not java!

Thanks for the info. I've been poking around with the oscilloscope and a CAN bus tool but nothing. I'm wondering if it's actually serial transmission instead of can but all the other pins match 100% with my unit.

Are you from Spain, since the links are in Spanish?:D

Ah... I really want to know how these CAN decoders work! Do they decode the CAN and send as Serial? Or do they filter CAN messages? :confused:

Sorry, can't see the last link, Error 401!

I'll go look for more info on these decoders. For now my oscilloscope is showing nothing and the can sniffer is silent!

Thanks!
[Android Head-Units] O.i.D:
Ok, looks like I found something.

On the 8 pin connector "C" when I go through the list of "decoder protocols" the message changes as well as the baud rate.

On the 6 pin connector "E" it looks like it spits out serial data during boot on the "CAN" pins.

The device lists a dev/tty, ttyGS0 to ttyGS7, ttyMT0 to ttyMT4, ttyS0 to ttyS3, ttyp0 to ttypf. So lot's of ports to try.
[Android Head-Units] t3l3m4k0:
Yes, I come from Spain.

I suspect my canbox converts canbus signals to serial levels and filter messages.

Probably devices to monitor are ttySX. Have you rooted your device?
