[MTCD  Android Head Units Q&A] jpreston84:
I've had similar problems with a KGL MTCD/MTCE unit (2GB RAM, PX5, with MTCD MCU). The problem isn't the ROM, but for reference, I'm running Malaysk's latest PX5 ROM. Most notably, I experience significant break-up using bluetooth for calls. Additionally, I'm unable to pick up WiFi from inside my house out in my driveway, though various phones and laptops can do this acceptably well.

We opened the unit, found bad soldering at the WiFi/Bluetooth module, and attempted to repair it. We replaced the antenna with an SMA pigtail and longer antenna, and removed a soldered short in the board. We then powered back up with the new antenna, and found the signal no better, and in fact possibly worse than before (we may have damaged something when trying to fix the module).

We also noted that there is a small antenna printed on the bottom side of the board. There were several problems with this. First, the "internal" antenna was "connected" (more on that in a second) to RF1. RF1 on the specs for this module as published by a number of sellers on AliExpress shows RF1 as being no contact. So, we're not even sure how that's supposed to work. Second, I said "connected" before, because the soldering was bad and apparently didn't really have a connection at all. Third, being an antenna on the underside of the board inside a metal case will probably preclude it from working at all anyway.

The biggest problem is likely metal under the dash of my car, which prevents WiFi from being picked up well under there. The antenna needs to be moved out from under the dash.

I considered getting an SMA extension cable to simply move the antenna. However, at the end of the day, I've ordered a USB module, in the hopes of getting it to work. The module is listed as "USB WiFi Bluetooth Adapter, Wireless WiFi Dongle Network Adapter 150Mbps & Bluetooth Transmitter Receiver with External Antenna for Desktop/Laptop/PC, Supports Windows 7/8/8.1/10/XP/Vista/Android" and sold by "iFun4U" on Amazon.com. The unit has a larger antenna than the Comfast unit previously mentioned, and appears to use the same Realtek RTL8723BU chipset that the onboard module uses (typo'd in the listing as "Realteck TRL7823BU"). Here's a link to it: https://www.amazon.com/gp/product/B01JYE5BT2

My hope is that by plugging this unit in and restarting the system, the wireless kernel module will pick up the external USB device first and register it as wlan0, making any further configuration unnecessary. If that fails, I'll look into ways to specifically assign my external device as wlan0. Worst-case, I'll open my unit back up and de-solder the USB data pins on the module.

I'll let you know how it goes.
[MTCD  Android Head Units Q&A] jpreston84:
Update -- on my KGL unit, simply plugging in the new WiFi/Bluetooth dongle caused the system to crash when booting. We ultimately had to disable the onboard Realtek chip by cutting the power trace to the board. After that, the system boots right up, and the Wifi works quite well.
[MTCD  Android Head Units Q&A] stefcio007:
wondering if this also means A2DP audio streaming is clear now too?
[MTCD  Android Head Units Q&A] newbie_vlc:
Which trace disable power on chip?

Someone test antes USB hub to confirm that It works?

Thanks you
[MTCD  Android Head Units Q&A] jpreston84:
Please check the post earlier in this thread by GeorgeM269, which shows pictures of the pinout for the board. To be honest, if you cannot use those to determine the pinout of the board, I do not recommend you attempt to cut a trace. You could destroy your head unit, and I accept no liability for that. Do this at your own risk.

- If you have opened the unit, and are looking top-down into the unit, with the face-plate on the top side, and the back panel on the bottom side.

- From that angle, on what I'll call the left-side of the small board, you'll see 4 connections, which are GND, RF0, RF1, CLK. RF0 runs to the antenna connection on the board.

- On what I'll call the bottom edge of the board, there are 6 contacts which have have no connection.

- On what I'll call the right edge of the board, there are 4 connections which represent a USB connection to the system. From top to bottom, these are GND, Data+, Data-, PWR (3.3V). The 3.3V power connection, on the bottom right of the board, is the one we cut.

- Check your results with a meter to be sure you've fully cut through the trace.

For what it's worth, this mod is still working without issues.

I'm not sure what "antes USB hub" is. I can tell you there are no issues with using the USB hub I purchased. Personally, I ended up plugging my USB WiFi/BT dongle onto one of the ports on the rear of the head unit.
[MTCD  Android Head Units Q&A] notime2d8:
I ordered this USB stick off eBay Link. It has the RTL8821CU chipset with Bluetooth 4.2, wifi ac standard, and 5ghz Frequency. The radio does pick it up as a USB device but it doesn't have a driver built into the kernel. I'm going to see if I can build a kernel module and get it to load. Just a little hesitant to try because if it causes the kernel to crash i'll have to lose my settings/info to restore it as I don't have ADB set up yet.
[MTCD  Android Head Units Q&A] sev:
keep us posted. this sounds interesting!

[MTCD  Android Head Units Q&A] stevey500:
Hoping this goes somewhere :)

I have already tried desoldering the included excuse of an antenna and replacing it with nice coax to SMA connector with a 2.4ghz antenna. I get much better range but I only get 1.5-3mbps but traffic just randomly stops. Sometimes it wants to to work at 10-15mbps magically but will eventually stop.

In the mean time, I will get a Comfast RTL8723BU dongle on the way and remove/rename the extension of the 8188eu.ko file to disable the internal RT8188EU module and see if this improves anything. The RTL8723BU.ko file is in there. It looks like you can obtain a RTL8723BU in the same surface-mount form factor as the included RT8188EU. With a hot-air gun, I bet it can be transplanted. I wish we had a kernel source to compile more drivers for these android head units. Spotify playlists would download in a pinch with a wireless AC adapter.

[Samsung Galaxy S8 Guides, News, & Discussion] yglup:
Hey guys, long story short, I work for a very big US carrier and Samsung is running a rep promotion through Samsung Elite app ( Training app for reps ) we accumulate points by having S7, S7 Edge, S8, and S8 Plus users download and register Samsung Pay to their devices and entering our rep code ( my rep code is " 4A37C " ) into the promo code field. Every time we get a friend, customer, stranger, whoever, etc. to enter our code it keeps track and awards us points in which we can redeem for various things. Only catch is that the user must be new to Samsung Pay App ( you can have an existing account, but must not have loaded a bank or credit card yet ). I'm asking if anybody with the time can help a brother out by entering my code " 4A37C " into Samsung Pay under the promo field ( under options or under promotions section ) and applying it. This does not prevent you from entering any promos you may in the future enter, nor is it a contest. I am just asking for the help from those willing to give it as support. What I can offer, is help with any Samsung Pay related questions any of you may have. :):D

Read through forum rules and not sure if this is appropriate forum for this, Mods if this post is against XDA rules or in wrong forum, please let me know and I will handle it appropriately.
[Android Q&A, Help & Troubleshooting] Macavity_AU:
I have a few Samsung devices still on Stock.

I want to be able to set some apps not to start on boot. I'm finding some apps starting at boot that really don't need to be (an archiving/unarchiving app for one).

I can't find a way in the device stock ROM.

Most threads listing app managers are old.

I don't want to Freeze or Disable them. I want them on the device. I use them. I just want to stop them auto-starting, at boot or otherwise.

Can someone suggest a good, non-bloatware, non-invasive app startup manager that is worth it? The main device in question does not have ROOT.

Thanks
[Huawei P9 Lite Questions & Answers] bmita:
Hi everybody!

I currently have the B362 stock version installed in my P9 lite, I wanted to use the "dload" method (with UPDATE.APP file copied on SD Card folder) to upgrade my phone to the latest B364 or B370 stock version, however when the phone starts in recovery mode the process stops at 5% and a error message is displayed and the only option is to restart the phone.

This method was previously used to upgrade to B362 version without problems.

Does anyone know where the problem is and how to fix it?
[Huawei P9 Lite Questions & Answers] pilgrim011:
Maybe the update is not compatible with current version.

** Unlocking the bootloader will WIPE your device!**

Update:

Tmo is unlockable

Sprint is unlockable

ATT is NOT

Verizon is NOT (Shocker!)

So I just got my phone and the very first thing I did was unlock the bootloader! It's very very easy..

1. Enable Dev Options and enable OEM unlock as well as USB debugging. If you don't know how to do that, what are you doing here? ?

2. Goto: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a

3. Agree to all the fun stuff then sign into your Motorola account. I used the handy sign in with Google button. Download and install the Motorola drivers as Motorola uses there own fastboot driver for some reason.

4. Open a command window and type adb reboot bootloader

5. If you have ever unlocked a HTC bootloader this will be easy for you. Put in the command it tells you into a command prompt then copy the entire string.

6. There is a option on the website that lets you paste it and it automatically cuts the unnecessary stuff out for you.

7. Paste the new string into the box, agree to the terms and in about 5 min you will get a email with your unlock code

8. Type fastboot oem unlock ^paste your code here^

9. You should receive a message saying your bootloader was unlocked.

10. Restart bootloader and confirm!

This is awesome news! I went back to best buy and ended up getting one through AT&T, currently typing on it now. I'm hoping the process will be as straight forward with the AT&T model. I'll give it a go when I get home and report back.
[Moto Z2 Force  Guides, News, & Discussion] filthyfnj24:
Looks like AT&T is locked down. After going through the above steps on Motorola's site. "Your device does not qualify for bootloader unlocking."
[Moto Z2 Force  Guides, News, & Discussion] filthyfnj24:
Has anyone figured out how to unlock the bootloader on the AT&T model?
[Moto Z2 Force  Guides, News, & Discussion] seniorstew:
If the website says no then it won't work. Sorry!
[Moto Z2 Force  Guides, News, & Discussion] filthyfnj24:
Do you think an ATT sim will work in a T-Mobile model?
[Moto Z2 Force  Guides, News, & Discussion] seniorstew:
If you buy it full price you can unlock it. Check the LTE bands first though
[Moto Z2 Force  Guides, News, & Discussion] filthyfnj24:
I think that will be the route I take. There's a couple of T-Mobile and Sprint variants floating around on eBay, I'm assuming from their BOGO offers.
[Moto Z2 Force  Guides, News, & Discussion] cliberti:
I can confirm Verizon is locked as well and can't be unlocked by the factory
[Moto Z2 Force  Guides, News, & Discussion] Shaffer678:
You got it straight from Verizon? I'm only asking because I got mine from Motorola and I'm wondering if than boot loader can be unlocked .
[Moto Z2 Force  Guides, News, & Discussion] bart bart:
I got my T-Mobile Z2 Force and was easily able to unlock the bootloader using the same method thru Motorola website. I was also able to confirm that "TWRP 3.1.1 albus" for Z2 Play does NOT work on this phone, it just freezes. For the love of god please someone get this phone rooted so I can delete all the startup crap and have a clean phone. Thank you in advance. :)

[Moto Z2 Force  Guides, News, & Discussion] XirXes:
It looks like we don't need custom recovery to install Magisk root anymore. The biggest problem now is that we don't have a kernel image for our current roms. Moto still hasn't released kernel source for the Moto Z2 Play yet so I'm not super hopeful about getting ours anytime soon. Betting we don't get it until after Android O is available.

[Moto Z2 Force  Guides, News, & Discussion] Team DevDigitel:
somone who has a device can DD the stock recovery image in download/fastboot mode.

As well you can DD the entire system.img as well to get a stock based rom put together.

Magisk should be able to patch the stock boot.img and get dm-verity patched and force encrypt turned off as well.

If somone will DD the stock boot.img and upload i can patch it so you can send it back to the phone. Same with the stock recovery somone needs to DD the stock recovery so we have a copy of it. We dont need source code for anything really, unless somone is trying to build a aosp rom for the device or to build a custom kernel. I can mod the stock kernel without sources, just cant add overclock, underclock, voltages etc. Same thing if somone can pull the stock boot.img i can pull the files from it to rebuild the z2 play twrp to work for this device.

really stock boot.img and the stock recovery being backed up is what i need to get started. I DO NOT HAVE MY DEVICE YET, so i cant test the work or verify anything but the things i listed i can do without the device if someone can dump me the stock boot.img.

[Moto Z2 Force  Guides, News, & Discussion] XirXes:
I've found stock rom images for the US carriers besides T-Mobile. I want to re-up them to somewhere else besides hellashadylinks.china before I link them here. It may help get a few Sprint devices rooted at least. Try and capture OTA updates when you get them, it's going to be our first option for root.

---------- Post added at 12:17 PM ---------- Previous post was at 12:01 PM ----------

Can you post a link on how to do that? I was attempting last night through adb and I can't get read permissions. I haven't found anything for fastboot and recovery won't open an adb shell connection. If there's a way to get it through fastboot I can definitely pull T-Mobile's kernel tonight. I should have the kernel images for At&t, Sprint, Verizon and US Cellular for you tonight either way. You could probably get TWRP working on T-Mobile with At&t's kernel.
[Moto Z2 Force  Guides, News, & Discussion] Team DevDigitel:
Otas save under Cahce on the device, we would need to either dump it off the device via fastboot, or have root access to get those ill get ahold of the stock images and see what i can put together, i really just need the boot.img so i can unpack and patch it for the sec checks, and get the default.prop file to build twrp. Thanks for info tho, its gonna be a week or so before we get all the stuff given to us from Moto, but its not gonna be like how it was for vzw, its a national handset, things will get going no worries!
[Moto Z2 Force  Guides, News, & Discussion] filthyfnj24:
Is root possible without unlocking the bootloader? I'm coming from a Sony XZ where you have to unlock the bootloader in order to obtain root. I returned the AT&T model after trying to unlock the bootloader and finding it was locked down.

I currently have a T-Mobile phone with an unlocked bootloader but it's essentially useless to me right now since it can't be unlocked for AT&T. If the AT&T model can at least get root that's good enough for me.
[Moto Z2 Force  Guides, News, & Discussion] XirXes:

That's a good idea flash our boot img on another device the use magisk and get root ( in my mind it is please let me know if it's a bad idea)
[Moto Z2 Force  Guides, News, & Discussion] mr turtle droid:
you can modify the boot.img in adb and fastboot flash it which gives the device root but its being a b**** so idk if this is gonna work
[Moto Z2 Force  Guides, News, & Discussion] joemossjr:
If we achieve root with that boot img then we should be able to dd the recovery img in adb which then we can make twrp with the rebuilt recovery then flash su
[Moto Z2 Force  Guides, News, & Discussion] XirXes:
Haha it's a bad idea. The boot images are device specific. There's a method to patch a non rooted device with magisk now but it requires our kernel images. I'd try it but the only image I don't have is the T-Mobile image. I don't want to mess with trying a different carriers kernel on my T-Mobile unit as I don't have a way back if it doesn't work. We have to wait for the first wave of OTA updates or figure out a way to dump the images from a non rooted device (unlikely). Hopefully Moto wants to be aggressive about pushing us Android O.
