Once the bootloader is unlocked John Wu's excellent instructions for rooting the Samsung Exynos devices did the trick.

I'd be interested to hear if anyone has success flashing a GSI image once rooted. My initial attempt with PixelExperience and AOSPExtended were unsuccessful.
[Samsung Galaxy Tab A series Questions & Answers] Magendanz:
In a moment of weakness I broke protocol and allowed VaultKeeper to disable OEM Unlocking. Now it's missing from the Developer Options menu. How did you bypass the waiting period?
[Samsung Galaxy Tab A series Questions & Answers] Magendanz:
Just a quick status update on my TWRP builds:

I've building successfully with prebuilt kernel and have managed to work around AVB, but it seems that TWRP can't be booted with a stock kernel on these devices. I have the list of changes that need to be made, but I'm in a holding pattern for now until the kernel source for the SM-T510/T515 is posted.

UPDATE: If you'd like to request kernel source be posted, you can use this online form: http://opensource.samsung.com/reception/userCountry.do

UPDATE 2: The kernel source for both the SM-T510 and SM-T515 is now posted on http://opensource.samsung.com.

Make sure your clock time is current

1. Disconnect any network

2. Disable clock auto update

3. Disable software update in developer settings

4. Disable auto update in software update section and do manual update (it will not work of course)

5. Change the date 14 days from now

6. Reboot and check

Disable Vault Keeper

After rooted, use your root file explorer and do the following:

1. Edit build.prop

Change ro.security.vaultkeeper.feature=1 from 1 to 0

2. Remove RLC folder

Delete /system/priv-app/Rlc

Here is a link to your unlock guide, had to search through all your posts to find it.

After using this guide and unlocking the bootloader. I am now unable to reverse this process. Play Store says device is uncertified. Am unable to see Disney+ and Netflix apps in play store. Really need to update this guide or remove the thread since root is unattainable as of late. OEM unlock option is now grayed out and it says bootloader is unlocked with no way of changing it back.
[Samsung Galaxy Tab A series Questions & Answers] elliwigy:
really? im sorry but just bcuz ur having trouble doesnt mean its "unnattainable"..

i am unlocked, rooted and everything just works as it should even d+ and netflix..

maybe u should give more details about your situation so ppl can help u instead of telling the op to delete or update the guide bcuz u cant watch the mandolorian.. just saying..

theres also plenty of other guides for all of your issues that you might find easier for you as well.
[Samsung Galaxy Tab A series Questions & Answers] dcillusions77:
When did you get your tablet? Cause the newest Odin is telling me I can only flash official files
[Samsung Galaxy Tab A series Questions & Answers] elliwigy:
had it a while now.. its a T510 Tab A 10.1"
[Samsung Galaxy Tab A series Questions & Answers] dcillusions77:
Yes same here. I think Odin is my problem
[Samsung Galaxy Tab A series Questions & Answers] elliwigy:
could be.. it took me a few tries to get it first time but after that i pretty much follow same steps and usually comes out ok..

im actually considering building a rom for it.. its been a long time since i made a samsung rom lol
[Samsung Galaxy Tab A series Questions & Answers] dcillusions77:
Ain't messed with Odin since the s3 and s4 era here. Not understanding why it's asking for only an official file :/
[Samsung Galaxy Tab A series Questions & Answers] elliwigy:
look at the guides lol.. a lot has changed since s3 s4 devices lol.. theres a very specific method for it to work.. if u miss one step then prolly need to start over.
[Samsung Galaxy Tab A series Questions & Answers] dcillusions77:
Might later it's not unlocked atm. Thanks for your time
[Samsung Galaxy Tab A series Questions & Answers] fritz.barnes:
I have the same device - Galaxy Tab A. My pc does not see the device when I do this bootloader unlock process discussed here - VolUp+VolDn+plug in usb.

Similarly, it took me quite a while to get to where I could boot into download mode and connect with Odin. Problem is that my pc does not recognize that there is a device attached, while in download mode, unless I get there by adb command (adb reboot download).

What I am trying to do is flash TWRP onto the device. (Coincidentally, my real aim initially is to be able to boot up automatically when power is received, which I think is the same thing you are trying to do.)
[Samsung Galaxy Tab A series Questions & Answers] elliwigy:
try restarting the device while plugged in but as soon as device turns off immediately hold both vol+ and vol- only
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
The problem is probably with your PC or the USB cable and not the tablet. Are you sure you installed the Samsung USB drivers on the PC? Make sure the cable you are using will charge at the "smart charger" rate.
[Samsung Galaxy Tab A series Questions & Answers] fritz.barnes:
Yes, 100%. And reinstalled them a couple of times.

Also the cable I am using is the brand new cable that came with the brand new device.

---------- Post added at 02:53 PM ---------- Previous post was at 02:11 PM ----------

No luck. Tried that a bunch of times in case my timing was just not right.
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
OK, let's backup. The first step is unlock the bootloader. The PC doesn't need to see the tablet to do this and you don't need Odin. You need the PC for this first step only because the tablet needs both the power AND data lines to connect. With the tablet off, plug the cable into the PC only, not the tablet. Now press and hold both vol up and down and NOT the power button. Only then do you plug the cable into the tablet. In a few seconds, a green screen should appear on the tablet with instructions on unlocking the bootloader. NOTHING needs to happen on the PC. Are you getting this far?
[Samsung Galaxy Tab A series Questions & Answers] fritz.barnes:
Yes, I am looking for the "Warning a custom OS can cause critical problems....volume up longpress: device unlock mode" screen, is that correct? I am there. (Just making sure because the screen looks blue or teal to me. Could be the device or my eyes.)
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
OK, hold the vol up till the next green screen appears and unlock the bootloader. The tablet should now do a factory reset and reboot with the bootloader unlocked.

edit: BTW, us old timers don't do "teal". To me the screen is green.;)
[Samsung Galaxy Tab A series Questions & Answers] fritz.barnes:
Ha, I may be as old as you are but my wife is an artistic type. I learn what I have to learn, to survive. (When I was in school we called it aqua.)

Okay....well that seems too easy. I have rebooted with bootloader unlocked.

What I think I need to do next is use Odin to flash the twrp file I have downloaded. Please tell me if I am on the right track. And again thank you!

(I see there is no OEM Unlocking option in developer mode. I'm guessing that is because it is already unlocked.)
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Yes, now is the time to use Odin to flash TWRP. Use the same two button method to bring up the TEAL screen but only press and release the vol up to get to download mode. Your tablet should now show "added" in Odin.

I am trying to flash twrp-3.3.1-6-T510XXU2ASK5-20200215.tar.md5 (37.8 MB) which I downloaded from https://androidfilehost.com/?w=files&flid=301961
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
What version of the stock ROM is currently installed on your tablet? The TWRP version needs to match. You may need to flash a matching stock ROM before flash TWRP or flash a TWRP that matches your current ROM.

edit: I don't think that is the problem. In looking at your post, it appears you put the TWRP in CS instead of AP. Is that right?
[Samsung Galaxy Tab A series Questions & Answers] fritz.barnes:
It has to match the build, right? Pretty sure it does.

I have Build PPR1.180610.011.T510XXU2ASK5 on the device. I'm thinking I just have to match the "T510XXU2ASK5" part, which I did.
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
Yeah. I just noticed you got the "official releases" error. I've never had that problem but many others have. Try searching to thread for "only official releases".
[Samsung Galaxy Tab A series Questions & Answers] kennyk09:
Hi, I just ordered T510.

I was wondering if I can ADB and delete bloatware?

Also, does this model still get updates for its system?

If yes, until when does it get updates?

Can you receive updates when bootloader is unlocked or when it's rooted?

Thanks
[Samsung Galaxy Tab A series Questions & Answers] lewmur:
It gets security updates on a regular basis. Won't get Android 10 till september. And, no, you won't get updates from Samsung with the bootloader unlocked. But if you install a custom ROM, the devs will furnish all security updates. Custom ROMs are also the best way to debloat.
[Samsung Galaxy Tab A series Questions & Answers] kennyk09:
What I'm planning to do is just debloat using ADB. So that I can keep receiving the official updates. When there are no more updates, then I'd install custom ROM.

One last amateurish question, you can't root without unlocking the bootloader, correct?

Unlock bootloader -> install TWRP -> install magisk -> root. These are the steps?

Thanks

I recently acquired a Tab A8 and i am attempting to go through the root process, its been years since I messed with an Android device. The dumb thing won't OEM unlock. I went through the 4 steps you have here and I am quite literally sitting on a downloading screen where it says its now in Download Mode. Been sitting for 30 mins...

Anyone else got this one:

https://www.amazon.com/gp/product/B07QV67XBW/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

So far I'm loving it!
[MTCD Android Head Units General] zerozoneice:
those 10" units are known to have a space between the display and the actual touch, resulting in almost a 3D / depth-like effect of the stuff onscreen (when watched from an angle, which happens usually where the driver or passenger are looking at it, no one is looking straight perpendicular to the screen). Is this also the case with this unit?
[MTCD Android Head Units General] scythe000:
Is it known under different names? I’d love to find a thread’s talking about software options. Anyway, I don’t really notice any kind of a 3-D effect, if you look at it from an extreme angle, it does look like there is a small gap, but I definitely don’t feel it when pressing on the glass. It’s a beautiful display, a lot nicer than I would have expected.
[MTCD Android Head Units General] scythe000:
Where are you finding the updates?
[MTCD Android Head Units General] zerozoneice:
yes, the display is beautiful, very good contrast and color saturation.

i've seen one installed in a car few days ago, and the first thing i noticed (was sitting in the passenger seat) was the depth effect. This effect is not present in all other units 7", 8" or 9". You could see it more in the launcher main screen (it was an Ownice), less in FM radio app or mediaplayer, navi, etc...

another thing that i didn't like was that for my car i had to cancel the airbag warning connector since the unit comes with own mask and for VW/Skoda the mask that is used for 8 or 9" units has a airbag connector. The Ownice 10.2" did not. Also an issue is the huge screen at night with white background apps which even at lowest brightness they still blow your eyes off :)
[MTCD Android Head Units General] mindriot:
I may buy the dsp version soon from ali express.

I need to find out if the mcu is an MTCE first, as hal9k will be developing his rom for px6 mtce, and i wouldnt be suprised if malaysk adds it too
[MTCD Android Head Units General] ikerg:
Dasaita manufactures only mtce units

Enviado desde mi SM-G950F mediante Tapatalk
[MTCD Android Head Units General] zerozoneice:
to clarify this, i suspect the ownice i saw had that 2.5D+nano screen, because my 10.2 dasaita has no depth issue whatsoever on its ips screen.

reg. airbag warning, it's just not visible, you need to take it out from the old cover together without unplugging it and just place it behind the screen. it won't give errors but it's not visible either...
[MTCD Android Head Units General] stokedcrf:
also no issues on my IPS screen either! Great unit for what it is. Of course there are little issues here and there like all units.

I rooted mine so I could freeze apps I don't need and really clean everything up :)

Has anyone looked at (somehow) adding HD Radio?

My Rav4 HU has this and I've found it to be much better at receiving a signal (where I live anyway). I'm looking at a PX6 dasaita unit on Ali (also), but they all have the 6686 radio chip, where the 6688 radio chip has HD Radio included. I wonder if the 6688 couldn't be somehow retrofitted? Yes of course there would have to be pin compatibility etc, has anyone looked at that by chance?

I'm so tempted to just buy one and say scr*w the HD Radio... but sadly it's about the only thing I use the HU for! it would be hard to give that up as I almost always have the screen off :)

Cheers, they sure do look nice, would love to have one. Not sure if it would suit my needs though, when all said and done.
[MTCD Android Head Units General] pritamjagtap:
Do you also have carplay wire/wireless chip on unit? did you see if that is able to charge your iphone with carplay on?

ALso have you driven longer than 2 hrs? with this unit ? I had PX5 and it used to reset over using it continuously for 2hr or more. and also PX5 was not charging iPhone while carplay was on.

If possible could any one update me on this?
[MTCD Android Head Units General] scythe000:
It does charge while doing CarPlay because it’s wireless so I just plug it into my charger. Works totally fine for hours on end. I’ve got an annoying bug with VLC thinking it doesn’t have delete permissions unless I manually grant it twice, but that’s unrelated. Also a bug with my iphones voice to text requires me to type a character first before it’ll pick up mic input, but I think it’s an iPhone issue.
[MTCD Android Head Units General] pritamjagtap:
So far looks good then.

I do not find any description on link you got on amazon, specifying about wireless carplay, i tried contacting Iris he replied that there is option to get carplay wire/wireless on PX6. I ask him to send me link to product he is yet to reply.

Did you have to specify Dasaita to get you wireless carplay? or its just standard now?
[MTCD Android Head Units General] scythe000:
I could be mistaken, but I think it's wireless. I hadn't asked for anything in particular, so it might be standard now.
[MTCD Android Head Units General] komatan:
I have dasaita - car play works on wire plus you have to have additional box/device ( can buy it in bundle with head unit). When iPhone connected through it - CarPlay works seamlessly and your phone is charging.

One more thing - you need to have application for CarPlay too.

Regards. k
[MTCD Android Head Units General] pritamjagtap:
Would you mind creating a video and share it over youtube? about carplay ? I am interested to see it.(& I believe most of us here wants to)

Cansomeone share his settings export from working dasaita px6 ?

My unit is ~2 months old and I´m experiencing restarts and hangs(mainly at first minutes after engine start) from first day also.

I have tried multiple SW re-installs + MCU updates, cable reconnecting, changing CAN module, SOM reconnecting (disconnect + connect), nothing helped. Unit is not overheating as it sits between 30-55°C.

I have also tried to borrow another unit from friend to test it and his unit is working fine in my car. He doesn´t have the Dasaita one!

There is MANYpeople with this issue and if the only possible repair is to replace the SOM board (150$) then it's really sad.

Open link, copy it from address bar and send it for US there ?
[MTCD Android Head Units General] Cameron32:

I can't find the link, my iPhone can't support download.
[MTCD Android Head Units General] marchnz:
All of this suggests a hardware QA issue. The MCU config file is simply config settings, people forget the hardware component and the LOW quality of these units. Applying a mcu config won't achieve anything.

Suggest sending it back, requesting replacement or refund. Dont hesitate, they will waste your time for a QA issue they probably know about in an effort to do nothing and keep your money.
[MTCD Android Head Units General] Cameron32:
We requested them for a refund, but keep refusing asked us to update the unit and reinstalling the unit.

Hi.

My C-hr 2018 dont have front camera. The rear camera image show in the mirror. But i want see in the radio. I dont see any cable available in the dash to connect with the radio.
[MTCD Android Head Units General] marchnz:
That's typical tactic, waste your time for long enough for dispute or warranty to expire.
[MTCD Android Head Units General] adicrl:
I did not know 2018 C-HR does that, is it a Toyota option now?

I have a rav4 model, also with no front camera, and the video inputs look the same on my unit. If your dashboard wiring did not have a rear cam input and your mirror cam still works, then you may be better off to simply disable the rear cam on Dasaita from the unit's factory settings. This way it will not attempt to process a signal that does not exist and you will not get the black screen when coupling reverse. I get occasional glitches with my original rear cam (image upside down, guide lines not showing).

Another option would be to get an extra rear camera, there are models that mount instead of a tail plate light (it comes with an LED light for the plate), but you might not want that if under warranty, plus extra wiring costs.

Did you get a response from the seller or maybe feedback from YouTube installation videos?

Yellow Triangle Alert Screen

Hey! I just got my Dasaita Max 6 installed by CarToys, into my 2013 Fiat 500. I have no steering wheel controls (CarToys said the included wires would not allow it). Any idea what I need to do in settings, or to buy to make it work? Also my odometer is blinking now.....

Also, while driving, a yellow triangle alert type screen will pop up, stopping all audio and button controls. It seems to happen when I hit a bump in the road, and won't go away unless I hit another bump. Any ideas on what that could be?

One last thing, does this stereo have support for an iPod? Thanks for the help everyone!!! :)

I know this is a somewhat old post but I just got a PX6 so I saw this and wanted to point out there's a thread on XDA about hd radios where I posted an apk to control the Directed hd tuner. I would check on ebay and see if there are any for sale but then I would start receiving unwanted emails etc. I'm still running the apk as part of my system.
