[MTCD  Android Head Units Q&A] nixfu:
First of all just to clear things up. There is two moving pieces. "firmware" and the android software ROM installs which some also call "firmware" sometimes just to make it confusing. The firmware is very low level hardware code that is installed onto the MCU which is a separate very low level hardware controller on the systems and is totally separate from the processor which runs android, the MCU's are in different models/revisions called MTCB, MTCD, MTCC. Go to your settings->about and look at the MCU type it will have the letters MTCD, MTCB, or MTCB in the hardware version. You have to load the correct firmware for the correct hardware type. If you load MTCB firmware on MTCD hardware etc.. you will brick it. You must load MTCD firmware on MTCD hardware.

There is also different ANDROID installs available for the units. Those are generally built specifically for a) the MCU version, b) the screensize, and d) the processor. So there is a specific build of android for the head units that have an MTCB MCU processor, are 800x600, and have a RK3188. If you have a different MCU such as MTCD, or a different screen resolution you have to find the one that matches your system.

2) Recovery using a USB stick or SD card is the best way to go. Usually when installing different versions(stock vs malysk etc) of the android system install (ROMS) you have to first do the wipe/clear from inside recovery because they can't be installed 'on top' of each other. Sometimes a change will also require a wipe to be done when installing even a newer version of the same system.

3) The recovery is in the hardware itself on these units. No need to do anything other than know the magic incantation and keypress sequence etc to get to it on your device.

4) Most of us backup our APPS/App Data using Titanium Backup. Most people don't chase every update because often updating the ROM software android on these units is generally basically a full new install and you lose all your setups and apps and you have to do a re-setup like a brand new unit when you update and its a bit of a hassle. Titanium Backup of your apps can help make that time a little shorter but it still is a bit of effort, so personally I only update every so often and not every version.

5) Most of the newer models seem to have better mics. I had a MTCB and I had to do the 'mod' to get mine usable, but on the newer MTCD I have now, the mic worked fine as is.

6) The BIGGEST benefit of FUSE is that it makes the 'internal' space look like a full 16GB+. The stock roms., only have 2GB internal (OS) space, and 16GB looks like a 'SD Card", so you only have very little space to install apps and you have to do the whole 'move apps to SD' thing to be able to install apps on that space. Also doing the 'move apps to sd' thing messes up the icons on apps lots of times. With the FUSE mod, you have a huge amount of space to install apps 'internally' and it just works much much better.

7) Generally the 'sticker' on the front does not matter, its the system/MCU type such as "JY, RA, etc." But I would stick with either the stock rom for YOUR brand, or use Malysk's install.

For Nexus 6 SHAMU​

I was tired of Google not releasing an OTA or factory image so I compiled my own ROM for NEXUS 6!!

- Based on NRD90M AOSP

- Stock Kernel

- Root and Busybox, Nexus Launcher, ugly leaked ringtones [coming soon]!

Download folder: https://drive.google.com/open?id=0B-CbH9Yv1OUWWXRlYmNNLUZ2dGs

Go to latest version and download the ZIP file, the folder image_files contains system.img/boot.img and others

What works/what doesn't:

havent tested it yet but please report what works and what doesn't

Bugs: you tell me!!!

First make a backup, in case anything goes wrong and then download the ZIP, wipe all except the internal storage partition and flash the ZIP then wipe the cache.

Changelog

Version 2:

Added N Preview blobs

Version 1:

Initial

PLEASE PRESS THANKS AND BUY A BEER!!11!!! DAE GOOGLE IS SLOW LOL
[Nexus 6 Android Development] mexiken:
I assume the stock kernel included does not enforce encryption????

P.S. Appreciate the work you did to get this out for us.
[Nexus 6 Android Development] konradit:
Yes stock kernel is included
[Nexus 6 Android Development] mexiken:
This didn't work for me Capitan. Says error, unknown command while flashing, though the script completes. Gets stuck at Google screen on reboot.
[Nexus 6 Android Development] konradit:
Mhh, I used MM blobs so that was kind of expected, will compile again with N Preview blobs

There is another ROM for Nougat: http://xdaforums.com/nexus-6/general/rom-useless-nougat-t3447372

Did the issue of Google Play services persist after a reboot?

Also did the Setup Wizard crash on you?

Can you take some screenshots :p
[Nexus 6 Android Development] Matt4542:
Don't flash this. Every time I try to flash the GAPPS it tells me that they're meant for 7.0 only and that I was on SDK 22 (5.1). It also overwrites TWRP, so have fun reflashing that. I'd suggest to wait for the Google images or wait for someone to release a proper build, not this hacked together junk.
[Nexus 6 Android Development] konradit:
I built the android_7.0.0 tag and uses N Preview blobs, it should not say API 22. You can flash system.img and boot.img separately, they are in the folder. This is indeed a hacked together build since Google doesn't seem to push anything, not even a statement regarding the status of the update.
[Nexus 6 Android Development] Unreal_Shogo:
Everything works on useless build on general section, so everything would work in this build. No FC on setup wizard

[Nexus 6 Android Development] derekr44:

EDIT: yup, Adreno 530 and above will support it. N6 has Adreno 420

[Nexus 6 Android Development] Unreal_Shogo:
Well, Qualcomm said they'll release the drivers first to Adreno 5XX family and then to 4XX and searching technical capabilities (wiki) the GPU can handle, so... I still optimist ????
[Nexus 6 Android Development] mexiken:
Still not flashing for me in TWRP. Same unknown command error and does not install the OS. Do I need to update TWRP or something????
[Nexus 6 Android Development] sebastianomodugno:
RIL don't work for me, but ROM is faster then DP5.

UPD: No any IMEI in settings :)
[Nexus 6 Android Development] garywojdan81:
If you're not using 3.0.2.0, then yes you do
[Nexus 6 Android Development] hackthis02:
That's what I guess. I'm guessing it's a Qualcomm issue. If your GPU can support Open GL 3.2 it can support Vulkan 1.0. At least 7.0 bumps us up to 3.2 from 3.1.

I would recommend the useless ROM over this not well done on the useless ROM everything seems to work.

Still thank you your work.
[Nexus 6 Android Development] 0vermind:
About to flash, but not sure how one would be better over the other. Both are compiled from source without any modifications. It appears both have same bugs as far as Play Services crashing due to permissions, and WebView apps. Easy fixes. Anything is better than what I have now--the partitions on my phone are badly corrupted from dirty flashes of ROMS and kernels. Been way too busy at the shop to worry about my phone. Nuking and paving tonight. :D
[Nexus 6 Android Development] HueyT:
Try PWn3R (Beanstalk Dev) version as it does not "force encrypt" and works OK except for call audio issues with Verizon (so do the other 2 AOSP versions here--can hear caller only on speakerphone mode and BT mode, but not through normal phone earpiece). It also works well with Open Gapps 7.0 Micro

[Galaxy Note II Q&A, Help & Troubleshooting] Juanjo1420:
Hi for all. I have a few questions.

When I activate the mobile data 3G indicator sometimes appear and instantly dissapear, the maximum speed that I have It's the H+

Is this normal? I use zuluman patch for the "No registered in network" problem.

And finally my IMEI doesn't match with the IMEI behind the battery label but the phone works perfectly. It's necessary restore my IMEI? I don't have a copy of EFS folder, How can I restore it?

Greetings and thanks in advance! :D
[Galaxy Note II Q&A, Help & Troubleshooting] audit13:
The imei in the phone should always match the label unless the phone is a refurbished unit?
[Galaxy Note II Q&A, Help & Troubleshooting] Juanjo1420:
I found it on the ground of a street one day. I try to found the owner but not luck. So I install it a Stock ROM downloaded because the stock one that the phone has was very bloated and then there start the "No register on network" problem so I install it the Zuluman patch and works well but recently I saw that the IMEI that the phone shows me doesn't match with the label one.

Greetings :D
[Fire Q&A, Help & Troubleshooting] ogpog:
Hi, having flashed a couple of fires I was curious to understand why we can't unlock the bootloader by copying one from an early (pre-5.0.1) image. Perhaps someone can critique this and fill in the gaps to help me learn?

I understand the general idea that an ARM SoC starts after power or reset by executing from adress zero in memory which must therefore be some non-volatile memory (ROM, but possibly something flashable). The general way it goes is that address zero contains a jump instruction to the entry point of some code that we call the "Boot ROM", all of which is in that non-volatile memory just mentioned.

The boot ROM has just enough capability to initialise RAM and load a secondary bootloader (SBL) into it from some other non-volatile storage such as flash memory (is this the UBOOT partition on the internal flash drive?). The SBL is what we know as the bootloader that responds to the volume-down key and can boot the system (kernel and ramdisk in 'boot' partition) or recovery (kernel and ramdisk in 'recovery' partition), or it can establish itself as a fastboot server.

This left me wondering why we cannot simply replace the SBL image with one from a pre 5.0.1 image that supports unlocking. I don't understand how downgrading can brick the device.

I don't understand the detail and haven't been able to find anything concrete to explain it. If there is, perhaps a link to it might help me. Or if someone can be kind enough to explain it ?

I was thinking that the inability to replace the SBL may be because boot ROM performs verification of the SBL to ensure that it is legit before executing it. I don't know if it does but I read somewhere that the SBL image contains a 40-byte header for this purpose and that the boot ROM contains a verification (public?) key.

I presume the boot ROM is in some flash memory that is inaccessible from the outside and I thought that it could not be modified which would mean that all the SBL versions would need to have been signed by the same key. But I think perhaps the boot rom can be modified and the key contained therein can be changed when upgrading. I am guessing - I'd like to know how this works...

anyway, enough rambling :D

Hi,

First of all I'm a complete noob,

I was on Marshmellow 6.0.1 (NO ROOT) and signed up for Android N beta and tried to update my phone to the beta version and started downloading it, in the meanwhile i had no idea how, but all of a sudden i got the Android N update when i thought that i was updated to android N beta.

So, i went ahead and updated my phone and then the problem started,

the system UI frequently stops working and puts my phone to the lock screen and i observed, this happens everytime i press the overview softkey

Any ideas, what might be the problem and how to resolve it?
[MTCB Android Head Units Q&A] mrtowel:
i got my new RK3188 based head unit 3 weeks ago (android 5.1), with CANBUS module to display varies car info in the unit and get the steering wheel controls working, last week my car displayed "Error: Transmission" (Skoda Octavia 2014), and my transmission box started to act weird (skipping gears).

First thing i did - was to remove the head unit, but the problem was still there, as my car is still under manufacturer warranty - i took it to repair shop (after installing the original head unit back), and got it back after four days - they said that the transmission computer has malfunctioned and they replaced it.

The nature of the problem (computer malfunction) and timing of it (two weeks after installing a head unit with CANBUS connectivity) got me worried - that maybe something with the head unit caused this problem.

has anyone every encountered this? can it even happen (is there any protection for such issues in the CANBUS protocol?)?

The problem with your transmission computer is completely unrelated.

[Nexus 6 Q&A, Help & Troubleshooting] mkmathers:
I've been running the Android (N) Beta program for almost a month now. Yesterday, when I picked the phone up, it just simply turned off. When I tried to boot it up, it got stock in a Bootloop. The phone would not go past the boot animation and the only screen I would get is "Enter Your Password), and after it, it's an endless bootloop. (I have not tried to do anything on the phone, just the official stock build from Google).

When I go into the Bootloader it displays the following:

[Nexus 6 Q&A, Help & Troubleshooting] mkmathers:
thing is, whenever I try to use NRT to fix the problem it demands for the Bootloader to be unlocked, and for it to be unlocked it should be restarted and so as NRT says, and since it's in a bootloop it's no good. Tried to unlock the bootloader via cmd like it would happen on android M you know after entering certain commands, then on the phone a message telling you your phone will be wiped appears, but the thing is, a new menu drops in cm telling as in repartition, format and stuff, and nothing on the phone appears, and to be honest I don't wanna be too foolish and wreck the phone or something, since these type of things are not in my field

[HTC Sensation] bijaybd:
Recently, my touch was broken so I replaced with from a shop. From that day my wifi wasn't turning on. But, after sometimes it turn on and suddenly again disappear. So, i go back to the shop and they assemble the phone once again very careful as they said nothing is wrong with the hardware. Now, it worked like 4 5 hours again disappear for no reason. Again i tried many ways search on google tried many solution even factory reset. I tried to drill the battery to zero percent wifi comes back again its gone after some times. Again I visited the shop they try to clean the phone antenna and everything. assemble it careful. Well it runs again and after few hours disappear. So, I tried to figure out what actually the problem. I remove the back cover and try touch the battery couldn't move it as it is fixed with glue. But, whenever I open the cover the wifi doesn't work. But, i try to move the battery and create pressure on it without even turning off the phone the wifi comes back. But, later again after few hours the wifi is gone.

When its gone sometimes it disconnecting and connecting again and again. Sometimes it even couldn't find the signal at all. In my area I find many wifi routers with mine too. But when the problem occur it can't find any network so Its not my router problem and other phone's and laptop are working well with my router.

The problem is that it suddenly disappear with no reason and I have no idea what is the problem ??

can anybody help me to fix the issue ?
