Wifi

So my wifi is not working properly.. It will connect, but not transfer or communicate from time to time. I decided to open my unit and take a look. What I found is a sloppy solder job. So my question is : is the wifi wire supposed to be connected to one solder point or 2? In my case it's connected with 1 and a half. (look at pictures)
[MTCB Android Head Units Q&A] agentdr8:
It's supposed to be soldered to the wire and shielding, which it appears to be.
[MTCB Android Head Units Q&A] dougie175:
Not sure what resistive buttons are, I am guessing buttons with some sort of resistance.

I have a civic and the buttons are like below

The controls were working perfectly, however I tried changing the mode button to a mute function instead of a play/pause function. The second I touched mode then the headunit seemed to go into what I think is called a boot loop where it just sat loading forever, turned it off and back on again and it booted up, changed the buttons back to play/pause and since then no matter how I press the button the track skip an mode buttons double trigger, the volume buttons however work fine.

The fact there were working perfectly and only messed up when I messed with the assigning of them make me think its probably some software issue I have caused messing about, get the feeling I need to do a clean install once I work out the perfect combination for me and hopefully it will cure the issue

EXACTLY,

The XDA Portal Posts, are supposed to be on the RIGHT side of the screen. At the top of the page, they start out on the right, but as you roll down the screen reading posts, the XDA portal Posts will suddenly switch from the right side of the screen to the left side of the screen. When it does this, they cover up the first 25% of all the text on the left.

You can even find the exact spot that the XDA portal post display will switch from right to left, and if you roll the mouse wheel 1 click back up, it will switch from left to right, over and over and over.

I was pretty sure it was something wrong with XDA's website, as it happens on any thread on XDA, not just this one, and it happens on both my work computer, and my home computer. This problem started yesterday, on both computers, and I use Internet explorer at work, and Chrome at home. I am not experiencing this issue on any other forum I go to, it is just on XDA.

I can try AD Block on my home computer, but that will only block ads, not the XDA portal Posts, and I cannot install anything on my work computer anyway.

Am I the only person experiencing this behavior?
[MTCB Android Head Units Q&A] dougie175:
Yeah I didn't have an issue with double SWC command before think I have messed something up somehow when I have been messing about. Im sure it is nothing a clean install wont fix.

As for editing the file I will do it on the PC and stick it on the GPS SD each time and use Terminal each time to make sure I don't mess anything up. Once I find the timing and settings that work for me I will do a complete clean install and start again which should hopefully cure my double SWC commands problem
[MTCB Android Head Units Q&A] clearchris:
Basically, is there a canbus adapter involved, or did you wire the buttons up to KEY1 and GROUND?

The reason I think a software re-install may help is because the buttons have been working great for the last 2 days before I messed about with the software and seem to have caused some sort of double command for each press

Ok so the cable should be soldered to 2 points.. I have a feeling that the solder point on the chip itself is bad. I can't really think that this is a software issue..
[MTCB Android Head Units Q&A] kjettern:
Ok! But one thing I think is a bit weird is that the wifi used to be working ok before.. I'm only tethering from my cell phone 1 foot away.. That's why I think it's a bad solder rather than the antenna? You still think it's the antenna?
[MTCB Android Head Units Q&A] kjettern:
Ok! Thanks for the good answears! I will try to touch up the antenna that's already there and then maybe change it if it's still not working properly. Don't really care about good signal, as long as I can hook up to my cellphone. Right now I can't even get a good signal from one foot away so something is definitly wrong..

Did you manage to solve your wifi problem yet? I had the opportunity to play a little more with my unit. Seems that when I set the over all dpi of the unit to 180 wifi reception is less prone to problems. I use Malayask's rom with next launcher and in that image I can set the dpi in : configuration (of Android) -> system -> dpi -> 2nd item (choose dpi yourself).

Can you confirm that the problems vanish or get less worse if you set the overall dpi to 180 too please?

Dunno, Microsh*t puts a 32Gb limit on Windows for FAT32 formatting, your ll have to install some software to do it which you may have to pay for.

Or you could use Linux - as Android is a version of Linux you may be able to do it on your headunit or phone if you can find an app that does it.
[MTCB Android Head Units Q&A] andr786:
it's 4gb and no i havn't formatted in fat32. is that what i have to do? it works on my android phone s4.
[MTCB Android Head Units Q&A] CARRisma:
Think I just found the answer to my question. The Windows GUI doesn't let you format drives over 32gb as FAT32, however the command prompt does:

FORMAT H: /FS:FAT32

Where H: is the drive letter. I haven't tried this yet but I'm hopeful.
[MTCB Android Head Units Q&A] typos1:

3G dongles in 4.2->4.4??

HuiFei/KGL has two versions of 4.4 out... one is for 1024x600, has app icons ripped off iOS and 3G dongles work fine with it... so far it is only found in new units with that resolution straight from the factory. The other is 800x480 and looks like it's specifically for updating the HU's from 4.2 to 4.4. It basically retains the look of 4.2 but updates to 4.4 and MCU V2.22.

I'm sorry for not reading around 200 pages of this topic, perhaps this has been answered - but when we update a HU from 4.2 to 4.4,

ALL

3G dongles stop working, it seems like there's no support for them.

Any advice on this?
[MTCB Android Head Units Q&A] typos1:
Never tried NTFS and I never mentioned it in my previous posts, but Linux (Android IS Linux) can read FAT32 up to 1Tb (most hard drives are formatted in FAT32 as its the most compatible format). So all of these units can read USB storage/hard drives up to 1Tb, although they have to be formatted in FAT32 or EXT2/3/4 and they may have to be re-formatted in FAT32 even if they are formatted in FAT32 already, before they work.

To find out more about this, read the Wikipedia page on FAT32.
[MTCB Android Head Units Q&A] Enc0der:
Great, so this is what I said .. format it to FAT32 (non-standard procedure for Windows XP/7/8) to make the HU read it.. I'm glad to hear that it will work with all of them.
[MTCB Android Head Units Q&A] typos1:
Right, think you may have missed my reply to your first post, cos I did say youd have to install some software to do it.

Microsh*t have put a 32Gb limit on formatting in FAT32 in their OSs to promote their new format - exFAT, so I dont think your ll have much luck, just Google it to find a free formatting tool for Windows or try searching for an Android app to do it. I dont use Windows so I cant help.

---------- Post added at 03:36 PM ---------- Previous post was at 03:31 PM ----------

Didnt know thats what you were getting at, as its been covered so many times in this thread already that you can use any HD up to 1Tb formatted in FAT32 and that Windows cant format more than FAT32 so if you use Windows your ll have to get an app to do etc, etc, etc.

Im in holiday for easter so was not possible for me try to solve this problem.. I can confirm that the only wifi with problems is at my home...signal isn't so strong ..out of the garden and I can't go close to the house with the car...I just noted that wifi at home with my KLD is unstable ...lost the signal sometime. ..not my galaxy...for this reason I have buy a wifi extender just to increase signal outside...it will arrive next week..my idea is that with this HU if wifi is not so strong or there is some interference is able to connect ...but remain 'gray' so no Internet connection....

I don't know if somebody found the same problem...

Anyway as soon will arrive my extender I will so what's happen....

If nothing change I will try to update my v2.20 with the 2.40 but I thinks is not the problem..

FAT32 format

I can confirm that the FORMAT H: /FS:FAT32 command in MS Windows does not work, as [MENTION=456516]typos1[/MENTION] predicted.

I found this page on the internet which suggests a few Windows based utilities which allow you to format a drive in FAT32:

http://www.online-tech-tips.com/computer-tips/formatting-external-hard-drive-to-fat-32/

I tried "SmartDisk FAT32 Format Utility", apparently from Verbatim and it worked perfectly. It's simply an .exe file so no need to install any bloated application for this simple task. Only took a few seconds to format my 128gb Samsung MicroSDXC card.

Not any that we have found yet, we tried running two Huawei modems: E173u-2 and a newer one, the E1750 - both worked fine under 4.2, and after we updated them to 4.4 800x480, 3G connection stopped working altogether.

Errrr... I work with HuiFei units daily, I have two units on my desk right now, one is a 4.4 1024x600, factory new, the other is a 4.4 800x480 that was updated from 4.2 with files from the manufacturer.

The 1024x480 one has an updated, "fresh" look with icons straight out of iOS, 3G dongles work without a problem, the 800x480 one basically looks the same (menus, icons, radio, etc) as their 4.2 model which I'm sure all of you know, but it updates to 4.4 and MCU V2.22. After the update all 3G modems stop working immediately.

I don't know what is responsible for the difference in looks. Is it because of the resolution, is it the MCU, whatever. They definitely don't look the same.
[MTCB Android Head Units Q&A] zorantoma:

[MTCB Android Head Units Q&A] NaviPR:
I have taken two HuiFei units:

- Factory 4.2, 800x480 (MTCB-KGL4-V2.08)

- Factory 4.4, 1024x600 (MTCB-KGL5-V2.22)

I wrote down everything from the "About" section of each unit - MCU version, Model number, S/N, Android version, Kernel version, Build number.

Then I updated the 4.2 800x480 to 4.4 using files from the manufacturer.

I compared it to the factory 4.4 and everything matches, except for the KGL number of course and serial number. Same Android version, same kernel number, same build number. So, I guess, in effect, the Androids are the same.

BUT, the fact is, that the 1024x600 has a different look to it, and I don't know what's responsible for that.

And, the most important thing, is that so far, after going from 4.2 to 4.4 800x480, NO 3G dongles work, at all.

music stops when using GPS-app

i got my unit 4 days ago. it came with firmware version 4.4.4_23012015 MCU MTCB-KLD-V2.30 which was extremely buggy (complete systemlockups all the time)

i reflashed it with KLD_4.4.4_1024x600_150113_rooted_light_reparted_init.d_v4.2 (from coudu) and updated MCU to V2.40.

my unit seems to run ALOT better now except for 1 thing so far: The music suddenly stops when using any GPS-app

i have searched this thread and came across #7906 . the reply on that was a new version firmware would be posted to fix this.

i have the latest firmware, but still have this issue.

it seems that it doesn't matter what player i use (default stock player "Music" or any other player like Player pro)

please note that my gps-sound settings are set to "mixing" and level is set to 0 (want just my music to keep playing and i don't want any gps-app to make any sound)

is there a fix (or setting) for this?
[MTCB Android Head Units Q&A] ga!nusha:
What GPS app are you using ? I have seen so far 4 people having this issue, me included. One user had tomtom, one sygic, i use waze.

At first i thought it was because i stopped the sound in waze. I reset the sound settings in the app and sound started working. But now it stopped again. It seems to be random.

I think it is a new bug. I am on 4.2 using viper fx. Haven't noticed the sound bug before installing viperfx. However, i have only used the unit 3-4 times before installing the new sound driver.

There is 4.2.2, 4.4.2 and 4.4.4. (not just 4.2.2 and "4.4" as you put it).

As I keep saying, the MCU is irrelevant to the Android update, they are separate things.

Have you searched the thread for a solution to your 3G problem ?
[MTCB Android Head Units Q&A] DJCannonball:
i tried the app that came with the unit (Sygic) and also Waze. The weird thing is, muisc keeps playing when i start sygic.

When i closed Sygic and started Waze, the music keeps playing for a while and when waze is completely started (screens are build fully) the music stops.

when i close waze, the music continues playing.

i haven't looked into viperfx yet, i have no idea if i have this in the firmware or not.

First up is a 4.2 updated to 4.4, 800x480.

3G dongles stop working after this sort of update.

As you can see, it looks exactly like a HuiFei 4.2 unit, same icons, menus are the same too.

Not seen the hybrid 4.2/4/4 before, strange.

On the fileserver there are versions of the proper 4.4.4 in both resolutions.

I was thinking you might have found a new version or something which is why I asked for more info.

Dont use a dongle myself, but if you do a thread search you should find some info on how to sort your 3G problem, I m sure I ve read that a few people have had the same problem, it definitely hasnt affected everyone though.

The MCU is entirely separate from Android and can be updated separately, you could try updating or indeed "down" dating your MCU as that may fix the problem, I do know that this has worked for some people in the past. (V1.77 I remember being particularly good for some people)

[MTCB Android Head Units Q&A] agentdr8:
Audio focus stealing by GPS apps is usually related to the Settings->GPS->GPS Application setting. If it isn't set to your gps app, and it isn't set to mixing, then it will take full audio focus away from other android apps. Also, if your headunit has a button for launching GPS, use it instead of using a launcher icon.
