[Android Head-Units] ExtremeMOD:
Sorry to hear that. Please try the following steps:

1. Completely disconnect your head unit from power, start Flash Tool as Administrator and execute the command: Format+ALL including deleting the bootloader

2. Run the steps from "Brick Recovery" starting with Step-6.

If the above doesn't work - revert back to your original firmware by restoring your backup. Share your System Info screen found in Car Settings as well as your build.prop file and we'll have a look.

Make sure the USB cable is properly attached. The firmware update should not take more than 20 min. If it does, it indicates a bad cable/connection.
[Android Head-Units] dustindavidson900:
My PC will not detect the head unit at all. I'll try the test point recovery tomorrow and report back.
[Android Head-Units] ExtremeMOD:
In that case, follow the full brick recovery guide in the OP but use your backup to restore it. Once completed, share the info mentioned in my previous reply.

PS try step 1 in my previous reply. Because the unit is only detected once you push "Download" in Flashtool and then connect the USB cable to your computer. Before that nothing will be shown in your Device Manager. If nothing happens in Flashtool then do test point method.
[Android Head-Units] vijay_joon:
you need test point method now to make that alive again , after shorting them for some 2,3 times,run flash tool ,select scatter and press download, then connect headhunt with a usb a cable...
[Android Head-Units] dustindavidson900:
Why would I need to short them for 3 minutes? Isn't shorting them while I connect the usb enough. That's what the test point instructions say.

Edit: I was able to recover using the Android 6 version of the mod. Could not get the Android 8 mod to work. Thank you for the guide
[Android Head-Units] ExtremeMOD:
Glad to hear it! Android 6 is the recommended option, hands down. I made Android 8 for those that can't successfully rollback to 6.

The unit you see in the pictures in the Android 6 post is a project of mine where rollback caused physical buttons to no longer work and I couldn't remap them either. So had to put together Android 8 package.

Hi, can I update my yt9216bj without disconnect it from my car?
[Android Head-Units] ExtremeMOD:
You absolutely can. However you need to disconnect it from car battery.
[Android Head-Units] vijay_joon:
i meant to say 2,3 times , my mistake , i amended, shorting them removes the previous preloader stuff , i may be noob here but this is what worked for me
[Android Head-Units] dustindavidson900:
The method I had to use slightly differs from everything I have read.

1.) I wired a toggle switch to my positive lead. Left it in the off position (no power to head unit)

2.) I connected my radio to my PC (most instructions said do this after)

3.) Pressed the download button in flash_tool.

4.) Shorted the test points and turned on the toggle switch. As soon as I flipped the switch the radio connected and flashed %100.

I actually soldered a button to the test points to make it easier and in case I have to do it again. Took me a minute but then I realized it's just the volume up button and the procedure is essentially the same as putting a phone into download mode.
[Android Head-Units] ExtremeMOD:
Soldering a button switch is indeed by far the best approach. However since the majority of folks here are very new to these types of units, the guide makers here aim to keep it as simple as possible.

You're correct about the buttons and their functionality but since the majority of these devices come without physical buttons, you need to force download mode this way.

Finally, test point method is only required if you mess up your preloader. This should rarely happen. The only times you need to write a new preloader is when changing Android API, i.e upgrading or downgrading. And of course if you modify some of the hardware inside.

The majority of times users accidentally delete the preloader from their units in FlashTool.

I have problem with my Unit (Ebilaen YT9216BF 2GB/32GB).

I installed your firmware, and try reboot to twrp (using command: reboot recovery).

After that my unit doesn't boot (black screen).

After that i want to install TWRP (by SPFlashTools as says Tutorial), but Unit was bricked.

My problem is i didn't make backup firmware.

Right now when i try to unbrick my Unit (using a lot of firmware versions) in SP Flash Tools has error: s_ft_enable_dram_fail (4032) (olso when using TestPoint in motherboard).

I think this error means that i have wrong preloader.bin

Any chance to unbrick Unit without having original firmware?

Information about Unit from motherboard:

B9216BF v0.5/C 32G

A005-B9216BF011(9.0)

20210220

Problem solved. I find correcr preloader.bin

[Android Head-Units] ExtremeMOD:
You could share a picture of your soldered button. Some folks here might find it helpful :)

I'm thinking of making a guide going for a permanent mod, where the soldered tactile SMD button will be accessible through a small hole in the back of the head unit (similar to how you access the RESET button). That way you can use a 'needle' to short the test points, rather than picking the unit apart every time.

And in the app at the bottom there is an option to choose from three options "Delete all", "Keep user data" and "Delete all and lock" what should I choose?
[Xiaomi Poco X3 NFC Questions & Answers] Abdullah.Csit:
Yes, you can rollback.

- Delete All - flash with format data.

- Keep user data - Flash without format (not recommended)

- Delete All and lock - flash with format data & Lock bootloader.

All methods are safe but it's recommended to not keep data.

You don't need to wait not even 1 minutes. you can unlock it immediately.

You can update your device through OTA (settings > About phone > check for update) to whatever update android 11,10,12....

Hi guys,

one more question of me. Hope to get some help.

I´m desparate. I want to organize my data on my OP7T via PC so I connect it to it, but, if I want to open the pictures of snapchat, instagram, facebook etc, then it shows in Photos of Windows, that the file is damaged or can´t be read. But in the normal Camera folder, I can see the pictures.

SO I always have to copy it on my PC if I want to look to them. Thats pretty annoying.

Does anyone also have that kind of issue? Would be nice, if someone could test it on his own.

AND also this annoying messsage come several times, if I pull out the cable of the phone. (the pictures are attached.
[General Questions and Answers] dmm3rd:
Hi,

I am hoping someone may be able to help me. I have a Samsung Galaxy S7 that is originally a US based Verizon phone. It's been on Verizon since I bought it in 2016. Never any changes/modification done to it. I recently ported it to T-Mobile in US. Verizon claims it is unlocked but it seems to still have some kind of network lock on it. On boot with a valid, functioning (tested in a different phone) T-Mobile SIM it gets a message that SIM is not a Verizon SIM, but continues to boot fully. Initially had no connectivity to T-Mobile network but after manually setting the APN it finally got messaging and phone calls to work but no mobile data (i.e. internet connectivity) thru T-Mobile. If I look at 'Network operators' under 'Settings' - 'Connections' - 'Mobile Networks' the 'Network operators' option is greyed out. Normally I would expect to select 'Network operators' option and there should be a list of Networks listed there but can not select it.

T-Mobile tech support says the phone is still locked by Verizon. Verizon says it is not. Neither will work to resolve the problem. Phone is not black listed. It's unlocked but it's locked!!

Have done a complete factory reset a couple different times with no change to any of the above. Not much else I can think of at this level.

So I don't know what to do... Try to do a ROM flash or something more root level to get rid of all the Verizon boot code (which it still boots with all the Verizon garbage) or something else to resolve this? I don't want to buy a new phone right now, so need to try to resolve this somehow.

Researched for similar issues. Lots of info on so many different things out there but most outdated and geared to earlier dates from when S7 was initially released along with Andriod 6.0. Or just isn't the exact issue I have. Any suggestions or help you can provide would be greatly appreciated!! Below is all the phone info.

[General Questions and Answers] xjim:
I have exactly the same situation. Did this get solved?
[General Questions and Answers] xjim:
I solved the problem!!!

You said your model # is "SM-G930V". The "V" at the end stands for Verizon! It will never work with anything else! Other phones have different codes for different carriers. I bought another GS-7 phone that was unlocked. It had a "U" at the end, standing for unlocked. It wouldn't work with Mint Mobile (T-Mobile) due to not having the right "bands" for transmission. Apparently newer technology have more bands.

I love the G-7 and found the GS-10E to be an exact replacement - the G-7 case even fits it (but the holes etc don't line up).

I bought a like-new version of the GS-10E for approx $150 from ebay and am 100% up and running!

Good luck.
[General Questions and Answers] dave678:
That's flat out wrong. All US S7's are the same hardware wise. The carrier's firmware determines which bands are enabled or disabled.
[Google Pixel 4 XL Questions & Answers] ADB100:
I recently purchased a pair of Samsung Galaxy Buds+. They are working, however the Samsung Wearable & Galaxy Buds+ plugin don't work properly.

I followed the instructions on getting them paired - Install the Galaxy Wearable app from the Playstore, open it and allow all the permissions, connect (pair) to the Buds+, let it install the Buds+ plugin and then again allow all the permissions. At this point it says I'm all set, however the app says 'Your earbuds aren't connected to your phone'. I click connect and I just get 'Couldn't connect to your earbuds' and can click 'try again'.

Bluetooth wise they are connected and I can play music and answer calls etc, however the Galaxy Wearable/Buds+ plugin app aren't working. I need this to be able to update the firmware on the Buds+.

I've downloaded the Windows Galaxy Buds Manager software and installed it on my Windows 10 notebook (that has Bluetooth...). This cannot connect to them at all. The instructions say to put the buds+ back into the charging case, close it and then re-open it. I do this and nothing happens. The buds+ don't appear to be in pairing mode in the case at all. I can pair them with Windows natively and they work for audio OK.

I am starting to wonder if they are counterfeit?

I have also tried with another Pixel 3a phone and the behaviour is exactly the same.
[Google Pixel 4 XL Questions & Answers] blackhawk:
They work best with Samsung phones. Only Samsung devices support the SSC codec which is the highest resolution codec for these. If your device supports LDAC use this codec, it's supported.

Try a network reset and clear the system cache.

Make sure Wearables has all needed permissions or it will not load. (I'm not sure if Wearables works on non Samsung phones.)

Test by trying them in a phone call to see if bt is connecting. You should also hear a brief tone when you place them in your ears.

Once Wearable is working properly it will prompt you if they're are updates or you can request it check.

Updating; leave case open. Make sure both buds are nested. Do not interrupt the process, it may take a few minutes. Don't move or use the phone. A bad flash can't be corrected except by Samsung.

I've updated them in my ears but that's not the preferred method.
