[Android Q&A, Help & Troubleshooting] scotttherobot:
Thanks for documenting this, this is awesome info. A while back I built a rudimentary SIP client for MC74 based on the AJVoIP SIP package. I gave up on it once my trial period for that package expired. It was quirky, with flaky audio and no LED control (which both now could be solved by the info in this thread), but I did have hookswitch (hangup/answer by picking up the handset) working.

In the spirit of documentation, the hookswitch is an ambient light sensor that gets covered or uncovered by the handset's earpiece. The original Dialer2 app reads the raw value and compares it to a calibrated set point to determine on/off hook state. Reading the path

/sys/devices/virtual/input/input0/event0/device/raw_adc

with a FileReader will get you the current value. For my device, off hook (answered) is a value below 110. On hook (hung up) is a value above 110. For my testing I just polled this file every 250ms but you could attach a FileObserver to it or something.

This is actually what I am working on with a unit that I got.

The phone I have (from the build.prop file):

ro.build.version.release=4.2.3-phone-5068355-southern-userdebug
ro.product.model=Meraki MC 74
ro.product.brand=Meraki
ro.product.name=capri_me1
ro.product.device=capri_me1
ro.product.board=capri

Currently trying to work on getting ADB working from within the phone and not just within the Clockwork recovery that I got loaded on it.
[Android Q&A, Help & Troubleshooting] drraccoon:
Getting a pretty close stock experience on the MC74 is totally possible with some dedication and work. For reasons I cant get into, I am unable to provide the steps / files that it took to get where I am, but I have a functional MC74 with working handset & speakerphone. The only next thing I need to work on is getting the "IR" sensor to hangup in specific Dialer applications.

I am using Grandstream Softphone dialer.
[Android Q&A, Help & Troubleshooting] alex39wkd:
I was able to achieve the same, except GS dialer is not scaled correctly.

Not able to post link to image, as I don't have 10 messages.

So it is a/6aQYsz6 on imgur

Did not bother to fix it, as my intent is custom PJSIP dialer (someday :)

Headset sensor, led, mixer - figured out.

The only mystery is "mute" button and the red LED behind it.
[Android Q&A, Help & Troubleshooting] rcky844:
Hey, I am interested but I don't have the device.

First of all:

You can install a GSI on a 4.1.2 based device, but you can't without creating a vendor partition, GSI is a part of the Project Treble released with Oreo. It requires a vendor partition to work. On 4.1.2, there's simply no device with a partition called vendor, so you can't flash a GSI.

But, if you have a fully working Android Pie tree, you can make a vendor partition yourself.
[Android Q&A, Help & Troubleshooting] jtthecanadian:
As you didn't mention that you couldn't share any information like the reply previous to yours, would it be possible for you to share what you used to get there?

As someone with only linux, networking and voip knowledge and that never played around with Android ROMs/ADB before, that would get me started as I can ATM only get to ADB.

Also, did you use the version of android already on the Phone or Flashed it with a new ROM?

Thank you!
[Android Q&A, Help & Troubleshooting] alex39wkd:
I have used "adb pull" (in recovery mode) to dump boot partition, just used path to it in /dev/...

Used android tools to decompress and unpack boot.

Changed ro.secure to 0 and something like "meraki usb debug" to 1

Repacked boot partition

Used adb to switch to fastboot

Flashed boot and boot2 with this image

Now it is accessable as normal Android phone, for whatever you might want to do with it.

Testing procedure to revive/recover MC74

There is a procedure to revive the MC74 -- to get root access, and install an open VOIP / SIP application to allow the device to be used as a VOIP phone on any SIP service (hopefully). Could ONE OR TWO people give it a try and report problems on github? The project is: https://github.com/reviveMC74/reviveMC74

It contains a python script and helper applications and files to somewhat automatically recover the MC74. It works for me, but needs testing and further development. The VOIP application works basically, but needs things like support some of the extra features of the MC74 and integration with various SIP services (like voicemail, message history etc). Remember this is code is not polished and needs work.

Holy crap! Awesome work! I just ordered one of these phones on Sunday as a replacement for my deskphone which is a Cisco 7961-GE that I have incorporated into my 3CX lab, this is sick! I can't wait to try it out! :D

I know, I know, you "can't get into how to blah blah" but how in the heck did you get the navigation / statusbar back? I can't figure it out for the life of me!
[Android Q&A, Help & Troubleshooting] jtthecanadian:
Did you manage to get a different version of Android running on your phone?

The version on it isn't supported by discord and the GS Wave Lite app doesn't scale properly.

Also, I can't seem to figure out either how to get that menu bar, I'm still using ADB to navigate through the phone ATM.
[Android Q&A, Help & Troubleshooting] Jacobwitt:
For those who are still subscribed to this thread, the project has really taken off since the initial posting!

We've got a website, subreddit, and github going to help further communicate and share our findings!

Thus-far we've totally gutted out all of Meraki's applications via an elevated system image, either self created, or via the image I created which is easily flashable via ADB sideload. We've also built a custom build of LinPhone that allows use of the handset, speakerphone, and all device sensors (LEDs, IR for pickup/hangup, etc.)

All the details are laid out on our site; https://revivemc74.com and if you run into any issues, feel free to ask on the subreddit! /r/reviveMC74.

Really proud of the team! We've come a long way!
[Android Q&A, Help & Troubleshooting] Greg Austin:
https://github.com/reviveMC74/reviveMC74 has a script and necessary files to root the phone and install automatically patch the boot.img to install a softphone app to allow the phone to be used on any SIP/VOIP provider. It's cool that you an also install (old JellyBean) Android apps.
[Android Q&A, Help & Troubleshooting] card1411:
I have been watching this thread for quite some time and have even Revived 2 phones. I'm impressed with the work done so far and very much appreciate it!

That said, I am curious why there hasn't been any comment about setting up this phone to work similarly to the way it did out of the box? It seems to me that the "Revive" is simply adding a phone app to a jailbroken tablet and any "native" functionality is lost.

Again, absolutely no disrespect to the progress and work done thus far. I simply pose the question.

I look forward to insightful comments!
[Samsung Galaxy Note 9 Questions & Answers] puddleofmud:
Dear All,

It's my first time converting from iPhones to Android. Happy to join this community to learn and share.

It was my first amateur experience flashing my Galaxy Note 9.

Basically, I flashed an incorrect BL file at Odin after OEM Unlock. Phone was running Android 9 and it was a N960N (Korean Model).

I downloaded the BL file from another forum that was apparently supposedly to be only flashed inside TWRP.

I was stupid enough to change that zip file into a .tar file.

After a successful flash at BL, the phone seems to be bricked. It is unable to go into recovery or download mode.

I've tried

1. (vol down + bixby + power)

2. (vol up + bixby + power)

3. (vol down + bixby)

Whenever I do this, the following message just keeps getting prompted "KERNEL REV. CHECK FAIL DEVICE:3 BINARY: 2 (BOOT)

The computer can't detect the phone anymore....

I was stupid. Please advise me. Could it be that on the hardware volume down button is faulty? I was having a hard time bringing it to download mode at the beginning. I used recovery mode to boot into download mode and then made this big mistake.

I brought it to a repair shop, they said the volume down button is working so its more likely software problem.......

Any solution?

Thank you in advance.

I need to report a bug,

I see there is no way for the applications to save files to the system.

For example, I have 2 applications that can export their settings to the file system, the first one when I go to "share file to..." I don't see the file manager to save the settings file, and the second one, when press "export settings" it says "storage access framework not available"

I read that is has to do with the Q and the apps, it's called Scoped Storage

https://www.xda-developers.com/android-q-storage-access-framework-scoped-storage/

So maybe it doesn't have to do with the rom development but the app development.

Other than that the rom seems great, battery is great with default kernel, no crashings. Thank you.

Hello, latest experience here after facing some bugs:

Clean flashed the 08/29 build...

I early flashed during July, so I was still based on FDE instead of FBE, now I am full FBE.

The TWRP by Reignz I was using was a bugged one, stucked on Gathering System Info during flash Nano Google Apps, flashing 3.4.0 R1 FBE fixed the problem of stuck Google Apps,

I also had libjni_latinimegoogle.so permissions screwed and no more Swype, a clean flashed fixed it using 06/21 Nano GApps in order to use also Meteo Inside Lawnchair

And in the end the big governors are now scaling down properly, before I had them always stucked above 2GHz even on standby.

Only problem I have right now is with latest Magisk Canary isn't able to Hide apps like SkyGO anymore.
