[MTCD Android Head Units General] TonyFerreira:
Need some help with a new PX6 Head Unit I just purchased from China for my Audi. I am new at this so I apologize in advance and appreciate any help.

Here is my information:

MCUVer: 415175bLZH-Q5-AL-7-190817[170325]

FrameworkVer: 9 PQ2A.190305.002.eng.work2.20190826.163102

AndroidVer: 9

APPVer: 2019082701T_1024X600_970

Nadflash: 16.86G/22.52G

RAM: 4G

UUID: 010E6A88-3BFD-00B6-0000-000100001A88

Is there an update for this unit.

Also this unit shows me the OEM UI, do updates need to be specific to Audi for the Audi UI to display?

Thank you in advance.
[MTCD Android Head Units General] marchnz:
Not an MTCD unit, you might have to try search.
[MTCD Android Head Units General] TonyFerreira:
Thank you for the reply and pointing me in the right direction.

[Moto G6 Questions & Answers] VineelKumar:
I have installed TWRP, in recovery when im trying to install dm_verity file i'm getting error - "unable to find boot block location". can someone help how to flash it
[Moto G6 Questions & Answers] Spaceminer:
You have to format data using the type "yes" to continue method. Then use twrp's menus to reboot back into recovery. Mount /system and /vendor in twrp then flash it. If you still have a problem, then try the 5/21/19 release of the disabler.
[Moto G6 Questions & Answers] WoKoschekk:
[MENTION=7718083]Spaceminer[/MENTION] No, that's nonsense! Data is mounted correctly and is fully unencrypted. See screenshot where you can read "Updating partition details... done" There's NO error message.

That's the first thing...

Second, there's no need to mount sth manually, the script itself will do this if necessary!

[MENTION=7045149]VineelKumar[/MENTION] Download the dm-verity-disabler.zip by Zackptg5 from

https://zackptg5.com/android.php#disverfe

This will work with your device.
[Moto G6 Questions & Answers] Spaceminer:
It doesn't show data as mounted. It shows the external sdcard as being mounted. And there is an error, twrp is giving error 1, and the disabler is also showing an error saying it can't find the boot block location. This means twrp isn't able to modify block devices or mount them properly. What I told him to do will fix the problem. The script doesn't mount anything correctly if twrp is not able to run the script... I know what I'm talking about. I wouldn't steer the guy wrong.

Edit: I'm definitely correct. What I said is actually mentioned in the official twrp thread for this device. It says; "If you format data (Not just factory reset) after decrypting you must reboot into recovery and format again." - direct quote from the instructions, under notes.
[Moto G6 Questions & Answers] WoKoschekk:
I flashed the same .zip with /data, /system and /vendor mounted properly and ran into the same error... (see screenshot)

To mount a device block it's not neccessary to have /data mounted.

The .zip is incompatible with Moto g6 - that's all!
[Moto G6 Questions & Answers] VineelKumar:
Thanks it worked fine. But for some reason the mobile was struck in boot loop(just warning message on screen saying, you have unlocked bootloader for couple of seconds and then same thing appears again), any idea how to fix it ?
[Moto G6 Questions & Answers] WoKoschekk:
Yes, do it manually. The disabler.zip does two things on your device.

1.) remove dm-verity

2.) disable forceencryption of /data

The magisk.zip also removes dm-verity within the installation process. So you don't need the disabler.zip for this.

To remove forceencryption you have to follow a few simple steps which are given in my instruction below:

preparation:

You have to be on the latest stock firmware with TWRP installed and nothing else.

Boot into TWRP and format /data (do not wipe it! you must use format). Then reboot directly into TWRP!!

Now let's start to remove forceencryption.

1.) place the attached .tar.gz file in your internal storage (/sdcard)

2.) mount /vendor in the options menu and open TWRP's terminal command under advanced settings

3.) type in (or copy it from here)

tar -xvzf /sdcard/fstab.tar.gz

4.) at next boot your device will be unencrypted

Now don't reboot your device and stay in TWRP to install the magisk.zip v19.3!! That's important to flash v19.3 instead of the latest v20.3 otherwise it causes a bootloop!! I don't know why it does but you can later update Magisk without any problems through the Magisk Manager.

Magisk will now remove the dm-verity during the installation process. That's a part of the installation script of Magisk.

When the installation of Magisk has finished you can boot your device into system. Maybe it reboots one time but don't care. Also the bootanimation will take some time due to unencryption of /data. That's quite normal.
[Moto G6 Questions & Answers] perfectswanson:
I appreciate your patience, WoKoschekk. I for one appreciate the guide and insight into the reason root must be achieved this way. I was using 20.3 and 18 the whole time. I was successful with your instructions the first time. It became stuck on boot after the initia reboot, so I pushed fstab and magisk again and it was fine. I remember that on one phone, encryption wasn't a problem if you had your pin or password. Could it be the same here provided there was no fingerprint assigned (might be the original pixel)? I'm guessing this TWRP can't decrypt? Just curious, because N/A balogna. :p
[Moto G6 Questions & Answers] WoKoschekk:
I'm glad to hear that!

TWRP for Moto g6 can't decrypt your data. That's the reason why you must disable forceencryption to use TWRP.
[Moto G6 Questions & Answers] kmssd:
I don't have a SD card, so I put the file into the TWRP folder. I then used,

tar -xvzf data/media/TWRP/fstab.tar.gz

Was that the right location?
[Moto G6 Questions & Answers] WoKoschekk:
/data/media/0 = /sdcard

/external_sd = external SD in SD-card slot
[Moto G6 Questions & Answers] kmssd:
Ok, I see now. Anyway all updated and rooted with your instructions, thanks.

[OnePlus 7T Pro 5G McLaren Guides, News etc.] ntzrmtthihu777:
Hope this helps! This has been tested to work on a device unlocked on 10.0.13,

and there is little reason to believe it won't work on others. Also, if you use the

msm tool for these devices, and wish to unlock and continue to get OTA updates,

you must use this package, as MSM relocks you, and will destroy reserve.img again.

Those of you who have used this, please keep an eye out for updates from TMO

and report back whether you were able to update.

Confirmed that it works with brand new OTAs. Several members of the TG group

took the update from 10.0.16 and 10.0.19 without issue after restoring reserve with

these packages.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] js042507:
Thanks for this. So just to be clear, I should be able to run the second part (fix reserve) only and this should put back the .img file so I could theoretically receive the OTA? Is the first part necessary at all? I am on 10.0.16 and would just like to receive the OTA directly. Of course, I would unroot first.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] LLStarks:
No, you need to do the whole thing.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] ntzrmtthihu777:
The first part is necessary if you are on any other version than 10.0.19. You would need a reserve.img dumped from 10.0.16

to ota to 10.0.19, and since most people unlocked before 10.0.19 came out, we're not likely to get ahold of reserve.img for

those versions.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] dstryrwiz:
Does the first part perform a clean wipe or just force the OTA to apply even with the file mismatch?
[OnePlus 7T Pro 5G McLaren Guides, News etc.] ntzrmtthihu777:
First part does not wipe at all, just an overwrite. It fastboot flashes all the non-device-specific partitions as dumped

from a phone which was updated from 10.0.13 to 10.0.19, so after the first bit, and then restoring the reserve.img, your

phone should in theory be exactly how it would be if you hadn't unlocked, except its unlocked. Confused yet?
[OnePlus 7T Pro 5G McLaren Guides, News etc.] dstryrwiz:
Understood. Just to be clear though, this overwrite doesn't result in a replacement of the data partition with a blank partition, correct?

I understand that it's technically not a wipe, but I just want to be certain by doing this process that I won't end up losing all my files and need to restore all my apps again. If I need to, it's fine, just want to know that will happen before I do this process if it will.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] ntzrmtthihu777:
Well, standard disclaimers apply for any sort of flash operation on your phone, but no, it should

not delete anything in userdata. The first script pack should not touch it at all, and the second one

doesn't do anything other than push a file and correct permissions and selinux context.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] La_anvil:
excellent. thanks
[OnePlus 7T Pro 5G McLaren Guides, News etc.] nickmc01:
Everything worked for me. Also looks like the Magisk patch works as well. So far no issues. Hopefully this will work with the next OTA update.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] NotATreoFan:
Very nice! I will probably take a shot of rooting my phone next weekend. Just got done setting my replacement phone up, and not in a rush during the week to do it again.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] dstryrwiz:
Update worked perfectly for me. Thanks for this!
[OnePlus 7T Pro 5G McLaren Guides, News etc.] Keepinitgreen:
directions are very unclear in batch for update part, says it was finished with the Super (after parsing all 12 parts) and then nothing and now when i closed out to try to do the reserve to the boot loader im getting into qualcoms crashdump mode and its saying corrupted force dump kernel_restart. Please advise.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] ntzrmtthihu777:
No, it was 'finished' with super. there are more images after that.

Can you get into either fastboot or fastbootd mode?
[OnePlus 7T Pro 5G McLaren Guides, News etc.] Keepinitgreen:
My apologies brother, did not realized there were more to flash. Just completed part one now to do the reserve.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] ntzrmtthihu777:
It happens. I amended the first post to say it would reboot on its own, I thought I had,

but it was only on the second part.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] Keepinitgreen:
All good man! Appreciate this dope workaround. I have intermediate experience with terminal so it's a lot of guess work haha
[OnePlus 7T Pro 5G McLaren Guides, News etc.] Gamesoul Master:
Is this still the case? And if so, would it be useful to have access to somebody with a locked HD1925 running 10.0.16?
[OnePlus 7T Pro 5G McLaren Guides, News etc.] jhofseth:
[MENTION=6692406]ntzrmtthihu777[/MENTION] , I wonder how hard it would be to modify all future snatched OTAs to completely ignore reserve.img? I did see one line in the last one mentioning a specific reserve size.
[OnePlus 7T Pro 5G McLaren Guides, News etc.] NotATreoFan:
You would need root at a minimum, and likely a functional TWRP as well. Once you modify the OTA, it will fail the signature check.

Hello!

my TyTn rings late. it rings after one second. how can I fix it. I have many OSs and Radios but it didn't fix. could you please send me a private message.
[8525, TyTN, MDA Vario II, JasJam ROM Development] eightball:
I think it depends on the filesize of the ringtone and/or where the ringtone is stored (on the device it should be faster than on the storage card)
[8525, TyTN, MDA Vario II, JasJam ROM Development] r35b3ct:
i have the same problem but bro the ringtone is being on device memory in either ways the only path is in My Documents>Ringtones

thats what i know :confused:
[8525, TyTN, MDA Vario II, JasJam ROM Development] Chrisofsweden:
There's at least a couple of threads on this topic already. Search for "ring delay" in the root of xda forums and i think you will find them. Hope you solve it!
[8525, TyTN, MDA Vario II, JasJam ROM Development] mlalahoi:
WHat you need is the RIng-Delay patch, 2 CABs atached, one of them should work for you. Just make sure you use a .wav file as your ring-tone and the problem goes away. Cheers

[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] rastaman69:
Maybe this will shed some light on the issue. I have two units pf Mi 9T Pro. A black and flame red. Both are updated to the latest MIUI 11 Android 10. Nova prime installed exactly the same each detail. The black one can show notification badges while the red one cant. Checked firmware, the black one has MIUI 11.0.3 Global, while the red one has MIUI 11.0.5 EEA. This is the only difference i can see on two phones. My question now is, can i flash from eea to global?

Update:

Tesla Unread does not work either.

Update 2:

installed Notifyer on top of things and set a test widget on wall. once a notification for the test widget came in, all the other notification badges

came back to life. success i guess.
[Android Auto General] sTingA_:
Now i checked the connector of the Display with an oszilloskop.

I could not find a datasheet for the "D5" of the Display, but i found a WD070GHL40AE-C3 from "HannStar" which look quiet similar.

The shown pinout matches the design on the board.

I found out, that the CLK Frequency is 1213 kHz and the RGB Input are all in sync with the clock frequency.

That makes no sense to me.

I followed up the traces on the board, and they go directly to the head board (PX5).

There is a parallel chip (GM8284DD) to the RGB and CLK line, but it seems that this chip takes the signals and converts them to the Chrontel, but I can't find any datasheet.

So it a software problem or the graphics unit has died ... any suggestions?

[OnePlus 7 Pro Questions & Answers] redpoint73:
bootloader-fastboot mode is the

only

time fastboot commands will work. I know you tried this "also". But I feel you are wasting your time trying to run fastboot when phone is booted (instead of focusing on the situation where fastboot should actually be working). adb and fastboot will not work at the same time by definition. Also, debugging does not need to be enabled for fastboot (only for adb).
[OnePlus 7 Pro Questions & Answers] fustyler:
I have tried it from bootloader and still the same on my pc it just says waiting for device.

What else can I try?
[OnePlus 7 Pro Questions & Answers] redpoint73:
Try a different cable, different USB port. Fastboot can be finicky sometimes. You can also go to Windows Device Manager, find the device, and see if you can manually select the drivers. There is a generic Android device driver that sometimes gets fastboot to work properly on some of my past devices. This is on Windows 7, haven't done this on WIn 10 yet, so not sure if it is exactly the same.
[OnePlus 7 Pro Questions & Answers] fustyler:
Have tried different cables and different machines both pc and mac
[OnePlus 7 Pro Questions & Answers] billyt1:
What's you gotta do is look up how to disable signature verification in Windows 10. Then once you done that stuff put your device in fastboot mode then on the window 10 PC open of device drivers find Android phone then bootloader update driver. There will be 2 choices for updating pick the on device one. Should do you right.

I had to do this after flashing the T-Mobile version to my international version with the msmtool and it locked my bootloader for me
[OnePlus 7 Pro Questions & Answers] mnemesis:
Since adb is working, do an adb reboot bootloader and it'll then boot into fastboot. If you can't get a return on fastboot devices at this point, it could be you haven't oem unlocked your phone yet.
[OnePlus 7 Pro Questions & Answers] fustyler:
I ran adb reboot bootloader from pc to boot phone into fastboot.

However fastboot devices ran from pc still shows no device.

[OnePlus 7 Pro Questions & Answers] Giri Prasad:
This worked for me as well. Just to make it clear, rephrasing his reply. After disabling signature verification on windows 10, connect your phone in fastboot mode & open Device Manager on Windows & look for Other > Android device.If it is found, This means Windows 10 is not having proper drivers to recognize fastboot device. Now install "OnePlus_USB_Drivers_Setup.exe" & it will show pop up for installing driver & after accepting(this is blocked due to signature verification in normal situation), Android device will be recognized in fastboot mode.
[OnePlus 7 Pro Questions & Answers] puyow18:
ugh. I've tried all of these suggestions and still can't get the device listed in adb while in fastboot.

I even used the TOOL ALL IN ONE without success. Funny thing is, that program recognizes my phone being in fastboot and has it listed. But if I try to flash a recovery from there, it opens a command window and ultimately says there was an error in connecting to the device.

Any help is appreciated.

I have a similar problem. I tried to disable the signature. Installed a new Redmi Note 7 driver. The phone is recognized as an Android phone in the device manager. In Orangefox recovery it is recognized with ADB command. In fastboot it is not recognized. In Orangefox I can't format data. So my ROM is not booting up.

Hi, I already solved this issue (but this only works for xiaomi phone (Redmi Note 7 to be specified), for other brands I think need to download your devices flasher/driver tool)

For Xiaomi user only

1. Download Mi Unlock Tool (https://mi-globe.com/download-xiaomi-mi-unlock-tool-all-versions/) (Version 4.5.813.51)

2. Extract the files anywhere you like

3. Run MiUsbDriver.exe to install the driver

4. Try fastboot devices command

I hope this helps you guys. The Mi Unlock Tool also useful to unlock device locked bootloader.

For other devices maybe can follow this tutorial

[Samsung Galaxy Note 9 Questions & Answers] mhamdyl08:
About a year ago, I downloaded firmware for N960F from updato and downgraded from Pie to Oreo using Odin and it went all so well.

This time around I'm trying to downgrade from Android 10 to the exact same firmware version I used back then, just downloaded from updato yesterday.

Thing is, is doesn't seem to want to flash.. When I use the csc file Odin gets stuck at the recovery.img step. If I use the home_csc file, flashing starts, but is frozen at the start of the system step and nothing happens.

What is going wrong and what can I do?
[Samsung Galaxy Note 9 Questions & Answers] Trex888:
You can downgrade to pie android 9.0 but not oreo since you jumped to android 10

Android 10 and android 9 pie is on bootloader 3 and oreo is on bootloader 2 & 1 so impossible to downgrade you Cannot go back to oreo.

Odin will fail to flash.
[Samsung Galaxy Note 9 Questions & Answers] mhamdyl08:
As I previously mentioned, last year I managed to downgrade from Pie to Oreo. Anyway, I just downloaded Pie firmware and tried flashing it and it does exactly like I said above, using each csc file, freezes at its respective step.

What could be the problem? Odin?
[Samsung Galaxy Note 9 Questions & Answers] paul_59:
As previously mentioned you can downgrade, but only to an earlier version of Android if the bootloader version is the same as the one you're currently on.

So Oreo came with bootloader 1 and later versions had bootloader 2

Pie came with bootloader 2, 3 and last version had bootloader 4

Android 10 comes with bootloader version 4

So from Android 10 you may download to later version of Pie with bootloader 4 only.
[Samsung Galaxy Note 9 Questions & Answers] Trex888:
Try factory reset first from recovery before flashing

.use latest version of odin

Try reboot your pc and different usb cable.

I recommend you to use patched odin from link below
