Did you let the let op9 update via OTA after you sideload BEFORE you reboot?
[OnePlus 9] papad13:
I didn’t sideload anything!!! I flashed it with twrp
[OnePlus 9] papad13:
To be honest ,the main problem is that after all that **** with the Indian op9pro msm.

I cannot go to android 12

Every time my screen freezes when installing the stable version of 12
[OnePlus 9] iaio72:
where you find the stable version of a12 for op9?
[OnePlus 9] papad13:
OnePlus Android 12 Tracker: Here are all the official OxygenOS 12 builds to download and install

OxygenOS 12 Open Beta builds based on Android 12 have begun rolling out to multiple OnePlus smartphones. Head on over for the download links!

[OnePlus 9] ctonylee1965:
You have to sideload OP9 from OnePlus website in temp TWRP
[OnePlus 9] lukebukowiec:
Thank you so much seriously, you and op both... I thought my phone was gone for good
[OnePlus 9] DerBaLu841:
OK, my phone was totally bricked and now i*am on Lineage. That is how i bring my phone back to life:

1. Download the Qualcomm Drivers and the MSM for INDIA

2. extract MSM and the Drivers (the CAB with 7zip)

3. connect your off turned phone with your pc and hold the + and - Volume.

4. Now your PC shows up QHUSB_BULK

5. install the Drivers manually on QHUSB_BULK

6. Now you have installed the QDLOADER 9008 driver

7. Start the MSM tool --> click next --> target to india --> sha256 to uncheck --> use lite firehose to check --> Start

8. just make a cup of tea and relax

9. Download ONE+ tools and the Universal ADB Drivers and the adb toolkit

10. After that you have to get into the developer options and check USB-Debugging

11. Now open the ONE+ Tools and "enable OEM unlock"

12. check the OEM unlock on your phone and boot into fastboot mode

13. ONE+ Tools --> 9 --> 6 --> y

14. after the reboot we need to check the usb-debugging again

15. Download the newest Rom for the OP9 OTA

16. Download the TWRP recovery img and put it into the adb folder

17. lets boot into fastboot again and start twrp via adb with : fastboot boot twrp.img

18. Put the downloaded OTA on the storage of the OP9 and wipe system slot a and b

19. install the OTA on Slot a and b

20. boot into recovery (not twrp) and format and wipe system.

21. reboot

Maybe on Lineage?

When you will get on Lineage you need to downgrade the phone first.

22. Download the rollback package from here and install it via twrp

23. after reboot, we need usb-debugging again

24. after that you need to boot into Lineage recovery and install everything via sideload --> follow these tutorial --> KLick

25. after all that you need to reboot and chill.
[OnePlus 9] kischde:
Something doesn´t work as expected. First of all, drivers were installed correctly - now the phone seems to not be detected at all, there´s the connect and disconnect sound over and over again. Where should my PC show QHUSB_BULK? I expected it to see in device manager but it isn´t.

Another question.. why do we need India MSM? My phone´s a European version..

Edit: found in device manager now. Windows telling me that best driver is installed already... So no changes until now :(
[OnePlus 9] kischde:
Damnit.. it worked ^^

After trying uncounted times it seems as if the MSMDT for Europe did the job. It started already.. Will now try to install LineageOS, too.

Thanks mate for pushing me into the right direction :)
[OnePlus 9] tonbonz:
Thank You!!! Amazing!!! Fixed my bricked Global 9 after a week of frustration using the MSM Pro EU tool, all 3 items ticked (Firehose lite, auto reboot, etc.) and target select EU. Little tip that may help (worked for me and I used a generic cable from Walmart): On Windows 10 check update in settings for Qualcomm port drivers . With these drivers installed run the tool in admin mode with your phone unplugged. Choose your settings, hold down the power button for about 20 seconds, plugin and immediately hold down the Volume+ and Volume- buttons, the tool should then recognize your device and you can press start. Took about 319s. Mine didn't auto reboot due to low battery but a few minutes on the charger and the One+ boot screen appeared for what seemed like forever but eventually booted and set up no problem. Now to get back to Global 9...
[OnePlus 9] EtherealRemnant:
Is there any way to actually get the device recognized as a global variant again? Even after installing stock global software, it's still recognized as OP9P by MSM as well as the OTA updater. I really just want to get it back to out of the box working order at this point and it's clearly not there if I can't get my device to be recognized as what it actually is...
[OnePlus 9] tonbonz:
I may be wrong but I swear that even while running the pro firmware my device was still recognized by the global model number LE2115. What version of the stock software did you install? Did you either flash both slots or take an update so the OP9P firmware is no longer installed on slot a? I went all the way back to 11.2.4.4 and sideloaded to both slots from twrp recovery. Hope this helps!!!

Apologies!!! I saw your thread after replying. please disregard😬​
[OnePlus 9] tonbonz:
After getting back to Global 11 OTA first tried to install the latest 12 update but the file was only 400 and some megabytes. Rebooted and still on 11 at which point OTA installed the latest 12 full system update of 4GB more or less. Rebooted and no touchscreen. Booted twrp.img and no touchscreen. Put the device back into EDL mode and the global tool worked no problem. Now OTA once again is showing the latest 12 update with a file size of 400 and some megabytes. Installing the full system zip using local upgrade fails. Likely just sideload the latest 12 full system update through twrp but is anyone else experiencing this?
[OnePlus 9] EtherealRemnant:
Yeah I just fixed it period. LOL. My phone is back running global software and running C.48 even with working touchscreen. :)

Now... to go mess it up again flashing ROMs 🤣🤣🤣
[OnePlus 9] mrkcw:
Thank you, this method helped me get my bricked t-mobile op9 working again. Just a heads-up, the link to lineage points to the op9p page
[OnePlus 9] stez827:
its the same guide for op9 and op9p
[OnePlus 9] liver20:
In my case error unsupported target o2

My phone is le2110...flashing op9 pro indian
[OnePlus 9] EtherealRemnant:
O2 is global so just download the global MSM.
[OnePlus 9] v_krishna@xda:
Same issue with me can anyone please tell me how to update to android 12 without freezing the touchscreen
[OnePlus 9] tonbonz:
I used adb sideload while in twrp recovery to install the latest 12 OTA update (full not incremental) to both slots and that did the trick
[OnePlus 9] v_krishna@xda:
i get an error repeatedly while using the sideload method "adb: failed to read command: No error", is there anything else to do?
[OnePlus 9] v_krishna@xda:
Please tell me in detail what to do?
[OnePlus 9] tonbonz:
I read in another thread that that's normal. I got the same notification at about 40% I think and everything was fine. Just means it finished. In twrp recovery on your device it should show it finished and if there were any errors. After doing the first slot, instead of rebooting to recovery, I rebooted to the other slot and repeated adb sideloading the OTA update.
[OnePlus 9] tonbonz:
Hey, have you had any luck? I was trying to remember exactly what I did or what I forgot. I was in kind of a panic at the time and everything is kind of a blur. I was revisiting my previous reply when it hit me that after dumping the payload.bin and trying to flash the individual images as directed in the thread I mentioned, I had to use the MSM tool to recover. This of course put me back on 11 and relocked the bootloader so rather than setting up my phone for the 100th time I went ahead and unlocked the bootloader before booting into 11. Once booted into 11 I did the bare minimum setup just to enable developer options and usb debugging and THEN I performed the steps to sideload the 12 update to both slots. I apologize for the brain fart!!!:oops: I hope you have already managed to fix your phone but if not I hope this does the trick and again I apologize...
[OnePlus 9] mugaintus:
Holy stinking sh*t it work! Thanks man. My new Tmo 9pro was about to go back and you saved it.
[OnePlus 9] FrankVGL93:
Just saved my phone as well, completely works! Thanks for it guys! You totally rock
[OnePlus 9] Phillis:
Thank you!

Bought the LE2115 from Alixpress for BF and the Indian version was able to unbrick the device!
[OnePlus 9] D7M:
I try to open msm tool when I open it it says (msm tool packed image does not exist )
[OnePlus 9] mirzafaisal:
Yes Its Worked :cowboy: but camera and Sim network are not working
[OnePlus 9] _MartyMan_:
After flashing Pro firmware, you can MSM To regular firmware.
[OnePlus 9] mirzafaisal:
SW

Yes I did the same and my op9 everything work fine thanks
[FYT Android Head Units] Stephen2898:
Hey guys

My first post on here so I’m hoping someone can help

Received the Teyes CC3 in the post today for my Astra GTC I’m not sure where to connect the power wire to the back of the radio for the reverse camera

There isn’t any loose wires on the loom for the power and the instructions just say to connect it to G3 ACC which I’ve attached a photo of but it isn’t clear of what to do

Any help would be appreciated
[FYT Android Head Units] mastrv:
In summary, the rear camera needs power when you want to use it and the head unit needs a signal (i.e. 12V) to determine when to switch the display to the rear camera.

The diagram shows that:

Power is provided to the rear camera whenever there is power on ACC...which means all the time the radio is on:

On the head unit side, the red wire is connected to G3, ACC, to send the 12V to the rear.

On the rear camera side, the red wire is connected to the red wire from the rear camera so that the camera receives the 12V and is powered.

The 12V signal to the rear camera is provided to the head unit when there is power on the backup lights:

On the rear camera side, the yellow wire is connected to the backup lights. Whenever you put your car in reverse and the backup lights get power, the 12V from the lights go to the head unit on this yellow wire.

On the head unit side, the yellow wire goes to G5 which signals the head unit to display the video from the rear camera

This is assuming you use the connection wire provided by TEyes that includes the extra yellow and red wires on both ends in addition to the yellow RCA jack that provides the video from the rear camera to the head unit.

Does the above make sense? Note that the diagram shows that the rear camera will always have power. I've seen comments that it's not a good thing to always have your camera powered as it may reduce the life of the camera.

Did your car already have a rear camera or are you adding a camera where none previously existed? If none existed, then you pretty much have to use the wire provided. If your car already had a backup camera, then other issues come up. Also, your car probably already has wiring going from the rear to your old head unit and you could use that.

Remember, this is only advice and you should confirm any of the information given to you. You take full responsibility for anything that you do... :)

FYI, I don't have a CC3. I have an older SPro / CC2 but the wiring for the rear camera is the exact same.
[FYT Android Head Units] gabol8000:
Hello, I appreciate your deatailed answer mastrv :) I also have a question with that topic. I attached diagram that shows connections on Teyes CC2 Plus.

There is a Note at top: "Connection on the yellow line will not be needed if you already have a canbus box and the reverse control line (G5 area) has been connected to the canbus box."

I have ordered a set for Chevrolet Cruze from AliExpress. I received a Raise canbus box (RZC as at the picture) in the set and according to the diagram and note, I do not have to connect the yellow wires.

Maybe it is about only the yellow wire on the head unit side but on the camera site I have to connect to Reverse Light Power Supply?

Please tell me how it should be.
[FYT Android Head Units] mastrv:
What year is your car? Does your car already have a rear view camera? If so, does your car have any wiring specifically going from the rear camera to the front / old head unit? Here's a portion of the schematic for my car. It shows specific wiring in the harness to the (old) head unit. I used this to connect to G5 to trigger the new head unit to know to display the video from the rear camera:

View attachment 5372513

You should know the wiring schematics for your car. Information is sent through canbus. Different car makes and models provide different information through the canbus. Depending on your car, it may also send the reverse status for your car. My car is a 2012 and the reverse information does not go through canbus. I run my head unit without a canbus module. Not sure if you can override this and have your head unit ignore this information or if you need to.

I'd say to try without connecting that wire and if that doesn't work, then hook it up as needed...unless you know for sure the information that goes through the canbus.

NOTE: My original rear camera built-in rear camera runs at 6.5V so I also had to adjust the voltage to 8.6V or a little over that so that the head unit recognized it. I believe the Android head units need at least that to trigger displaying the video on the screen. Yours may be different so you should verify that. However, if you use a camera your purchased or that was provided by the vendor, it probably runs at 12V so you should not have to make any changes to voltage. Again, you should verify this. I did testing on the kitchen table before installing the head unit. I also did voltage measurements with a multi-meter on the old head unit wiring to verify voltages, etc.

As always, this is only advice and you are responsible for anything you do. If you're not comfortable doing this, have someone else install or wire up the head unit that knows how.
[FYT Android Head Units] gabol8000:
Thanks for your answer, my car is Chevrolet Cruze (year: 2009), it neved had build in camera or any camera. Unfortuantelly I don't have wiring schematics but I try to do things as on video tutorial created by Teyes:

I'm just not sure about the reversing mode.
[FYT Android Head Units] mastrv:
So, you got the canbus module. Are you sure you need the canbus module? What do you need it for? Usually, the following are some of the functions that canbus can provide for the purposes of a head unit:

dynamic parking lines when in rearview on the screen

as you don't have a factory rear camera, you don't have dynamic rear parking guides

reverse engaged status

with no factory rear camera, this status is obtained from backup lamps as described in diagram/instructions

I believe some even have video through canbus

no factory rear camera so the video comes through the new wire you must install

radar from rear sensors

do you have these? If so, do you absolutely need them on the head unit?

steering wheel control buttons

do you have steering wheel control buttons?

If you don't have these buttons, you can purchase a separate control with buttons and wiring and connect it directly to your new head unit such as this one:

https://www.amazon.ca/Joying-Universal-Steering-Control-Android/dp/B08R6VK9PN

there are several styles of these available but they all essentially provide several buttons available to you where the modules connect to key1 and key2

If you do have these buttons, you'll need to find out where the wires for the buttons are or if the steering wheel control information comes through the canbus. If you can't find out about the canbus info but know where the wires are, you can try to connect the wires to the key1/key2 wires on the head unit. If you don't know where the wires are...you can always purchase a separate steering wheel control module as if you did not have any steering wheel controls

controlling automatic climate control

is yours automatic or manual?

this does not normally matter. As long as you can set the climate controls without the need for the head unit, then you can live without having this info go through canbus.

my car has an automatic climate control with it's own buttons and settings. it did not go through a screen for any of its settings.

You should try to get the schematics. Try looking around on through Google. Never know what you can find. The schematics can answer some of the above questions if you don't know.

As your car did not have a factory rear view camera, it most likely means you have to put in the wire from the new rear camera you install to the head unit. If you don't need the canbus, you'll have to wire the yellow wire as described in the instructions. If you need the canbus, then you don't wire the yellow wire as also indicated in the diagram/instructions.
[FYT Android Head Units] mastrv:
@gabol8000 I just had a quick look at the Cruze install link you posted. It did not use a canbus module and they connected the wire to the backup lights for G5.
[FYT Android Head Units] gabol8000:
Well I will use canbus box bacause I want my steering wheel buttons to work. So in that case you think I don't have to connect to 12V Reverse Light Power Supply?
[FYT Android Head Units] mastrv:
If you are using a canbus module, the instructions say not to connect it...correct?

So, don't connect it and see what happens. Nothings going to break. At worst, there will be no image. At best, you'll be finished.

Then...if no image, it probably means your canbus doesn't have that info. Connect the wires and the image should appear.
[FYT Android Head Units] gabol8000:
I will do so :) I found a second video (newer) where the installation process is slightly different: there is no connection to reverse light and canbus box is used.

Here is full diagram of connections in my device:

https://cc2p.teyes.ru/en/map.html
[FYT Android Head Units] mastrv:
The connection diagram is pretty much the same for the SPro, CC2 and the CC3 with maybe some minor variations. In any case, the question is what information does your canbus provide to the head unit.

Let us know what happens.
[FYT Android Head Units] gabol8000:
I have installed the device and everything works fine but with some minor issues with 1 or 2 applications but it is thing for another subject.

I did not connected the yellow wire on both sides :) there is no need to do it - the canbus is providing informations about reversing. Camera works great.

The only little problematic thing was that I had to strip the insulation from the G3 ACC wire so I could connect it with camera ACC wire.
[FYT Android Head Units] startas:
Yeah, i dont really understand the difference between yellow cable + red cable and only red cable combos on camera video cable either.

When you have a video cable with both red and yellow additional cables, then camera gets the power from teyes device (red cable from camera power cable connects to red cable from video cable, and near teyes device, red cable from video cable connects to a loose power cable (number 3 on scheme) that comes from teyes power cable bundle), and yellow cable acts as rear gear detection switch - yellow cable near camera connects to rear driving lamp cable of a car, and the yellow cable near teyes device connects to a loose cable (number 5 on scheme) that comes from teyes power cable bundle. Then when you turn on rear gear, teyes gets signal from rear driving lamp, turns itself into special mode for camera only, and sends power to the camera. This method works, i have done it.

But when camera has a video cable with only red additional wires coming from it, then i dont get it - do you need to connect camera power cable to a car cable that always has power, or to a rear driving lamp power, and then connect red cable as a trigger wire ? Is there a difference of camera getting the power from car directly, or from teyes device ? Why there are 2 variants of rear camera video cables ?
[FYT Android Head Units] Bob_Sanders:
The yellow cable is the TRIGGER signal from the reverse light to the head unit, which tells the head unit to change its input from what ever it is presently on, to it reverse input. The red cable is POWER (12 volts) going to the cam so it can power up. (If you have CAN BUS and a can bus adapter, then the yellow in most cases doesn't need to be connected. The can bus will deliver the reverse signal).

It doesn't really make a difference where your cam gets its power from (the red wire), just so long as you are feeding it 12 volts any time you wish to use the cam. It's just more convenient getting it from a dedicated connector on the head unit.
[FYT Android Head Units] startas:
Ok, but how about all the cars that dont have CAN BUS - there are plenty of rear cameras for those cars that have video cable without yellow wire, only red one. Do you have to use red wire as trigger wire, and give camera power directly from the car (power from always on source, or from rear driving lamp) ?
[FYT Android Head Units] Bob_Sanders:
I have a video cable with only a red cable... no yellow. I also have can bus so I didn't need the yellow, but if I didn't have can bus, I would have to run my own yellow wire.... either that or use the red one as the trigger wire and run another power wire from somewhere.
[FYT Android Head Units] hawk30:
Just installed Teyes CC3 with video converter box in my Wrangler JL 2021, to use the factory reverse camera.

Had to try few ways to connect it, but when you take a moment, then realize it is simple to do.

If anyone has issues - let me know, I can share my experience.

P.S. I did confuse 2 factory connectors (rear cam and radio antenna - last one is the thicker one). Turned out the factory rear cam was the tiny one. Otherwise make sure to connect to separate yellow CAMER IN RCA plug, and do not cut pink wire on converter box.
[FYT Android Head Units] Simonjames91:
I have the same issue I think, I have a Toyota Hilux SR5 rear camera is not working I have can bus installed could you share?
[FYT Android Head Units] Simonjames91:
Has anyone installed a 6V factory camera to the Teyes screen?
[FYT Android Head Units] Bob_Sanders:
The camera voltage shouldn't matter to the head unit being used.... just don't connect the camera's power leads directly to the head unit or you may blow the cam. You will have to use DC to DC converter (or similar) to drop the voltage to power the cam.
[FYT Android Head Units] hawk30:
Few things to check:

1. Make sure you connected to separate Teyes connector with marking Camera In ( not CVBS in)

2. Try all car plugs to connect to that port mentioned above.

While running the car and when you put in reverse, if Teyes switches to camera - then you have setup CAN box properly.

Thats all I think.

Note, on my car you can watch the reverse camera anytime via menu. No need to put in reverse. On Toyota it might power the camera while running engine only, not sure.
[FYT Android Head Units] JoRastaf:
Yes. In my car, the factory fitted reverse camera works on 6v. I used an AEROPRO harness to use the existing reverse camera wiring and connect it to the CC3. The aeropro harness connects to the factory reverse camera cabling (plug and play) and gives you an RCA video output that you feed the CC3. You do however have to make one wire connection for the reverse trigger. Which is easy enough. Aeropro harness has a reverse trigger wire and you connect it to the reverse trigger wire on the CC3 harness
[FYT Android Head Units] Knyman:
Don’t think you shall connect any power at the unit. Camera gets its power at the back of the car, from revers lights if I remember correctly.
[FYT Android Head Units] Bob_Sanders:
Not necessarily.

If you want the cam to work all the time then you need to connect to a power source which is on all the time. With the cam powered by the reverse light you will only be able to use that cam in reverse and not as a monitor while forward driving (a great many headunits come with the ability to use the reverse cam as a monitor)
