So, like an idiot I got excited about rooting my phone and my first big mistake was not making a backup. I followed all the steps in the video titled "Official Android 7.0 Nougat on Moto X Pure Edition!" by HereGadgets on Youtube.
Now I'm stuck at the "WARNING BOOTLOADER UNLOCKED" Screen. The only difference I can find in my process was that when I was going through the process it said "Slot Count Not Found".
I have tried to use the "Moto X ToolKit" but it can't connect to daemon.
Also (if it means anything) when I'm in my bootloader it says "Status Code 3".
Yes I know that I am very dumb.
I tried to reflash to a factory default, and it says "Not supported command in current status". So I think I would have to access the "Allow OEM unlock" option in developer options, which I obviously cannot do since my phone is stuck on the screen.
I'm quite hopeless but if anyone can shed some light on how to fix my issue I'd be forever grateful.

Sorry for the incorrect forum, but it appears there is no such forum for my specific device.
So story goes, I rooted it about 6 months back, lost the charger and stopped using it for maybe 2 months, found the charger yesterday, turned it on, was prompted with a System Update upon connecting to the internet, update failed, tried to do a hard reset (pwr, vol +, lock button) - it returned the message "Unrecoverable Bootloader Error (0x19000008)"
After receiving this message, I am unable to boot the device, it hangs at the "Iconia Tab" splash screen.
I tried various methods found online, including one where I put the device in the "fastboot mode" with the series of buttons previously mentioned, went as far as trying to execute the command "fastboot oem unlock" and other variants of the same command or related commands, and all of them lead me to "< waiting for device >".
This puts me in an uncomfortable position, as I am fairly tech-savvy, and normally capable of knocking out minor inconveniences such as this one.
I am fairly familiar in the android/rooting/rom'ing world with phones, and the methods used for this device were very unfamiliar, and confusing. Normally I'd just use the fastboot files to restore it to stock, and be done with it, the methods with this tablet are confusing and most solutions people have posted have been unsuccessful in my aid to fixing this.
So I ask you ladies and gentlemen, what can I do?
Any and all help is greatly appreciated, and thank you in advance.

Will it boot to the stock recovery? If so, do some searching for a a200 rom or update. If it's an update, then you'll need to decrypt it (look in the Themes and Apps forum for the decrypting tool. It should be one of the first threads). After decrypting, open the zip, and pull the "update.zip" (do not extract), and copy that update.zip to your Ext SD card. Reboot to the stock recovery and see if it installs it. Might have to try several a200 update.zips before one works.

Please correct me if I am wrong, but the power + volume + lock toggle is the method used to get to the recovery?
When I try that it gives me that bootloader error and will not proceed any further.

I recommend trying in the Acer A200 forum here: http://www.acertabletforum.com/forum/forum.php Does your PC recognize the table when it's plugged in? YOu could try to reflash the bootloader. Just throwing out a couple of ideas.
Hi folks,
I've browsed a number of other threads looking for an answer, and tried a number of methods but I feel like further attempts without asking for help are going to be shots in the dark. The issue I'm experiencing is really strange to me, as the device will boot all the way into the OS before rebooting itself after a few seconds. This is my friend's tablet, and I assumed it would be fairly straight forward for me, but that was an incorrect assumption. All apologies if there's a clear cut answer to this solution posted somewhere, I spent quite a lot of time between reading threads here and various search results before finally swallowing my pride and posting here.
Anyway, what the device is doing: It reboots within seconds of booting up to the lock screen (which is responsive to input sometimes, but not others). When it is responsive, I can unlock the device, but I'm not able to do much else before it reboots. As far as I can tell, ADB debugging is not turned on, but "adb devices" returns the device SN when in recovery/sideload mode.
I am able to access fastboot without issue, which displays the following:
PRODUCT NAME - grouper
VARIANT - grouper
HW VERSION - ER3
BOOTLOADER VERSION - 4.23
BASEBAND VERSION - N/A
SIGNING - not yet defined
LOCK STATE - LOCKED

I can issue a "fastboot oem unlock," which will bring up the unlock confirmation screen. Here, one of two things will happen.
It will either drop back to the fastboot screen with "Unlocking now......" displayed in the upper left corner of the screen and do nothing, or start the bootloop described above. On the PC side, I get "FAILED (remote: ()"
In recovery mode, it says "Android system recovery <3e> KTU84P." and I'm able to push files via adb sideload (though I had to install Koush's universal ADB driver) . I tried applying the signed-nakasi-LRX21P-from-KTU84P zip, which made it all the way to "patching system files," before rebooting, so I thought I was going to be in good shape, but the bootloop returned. I've also tried sideloading nakasi-ktu84p-factory-76acdbe9.tgz, as well as the image-nakasi-ktu84p.zip from inside the .tgz, but I get "E: footer is wrong, E: signature verification failed."
Even trying a data wipe/factory reset from recovery mode doesn't seem to do a thing, despite it claiming to wipe the cache and data partitions.
Anyway, I'm optimistic considering the tablet is booting (or at least kind of before rebooting). I've tried both the Nexus Root Toolkit (on two different win7 machines) and even went so far as trying it all manually via what they're now calling Android Studio and its dependencies. I'm wondering if either a) there's some kind of image that doesn't require the bootloader to be unlocked (as I was hoping would be the case with the above reference signed LRX21P/Lollipop update zip), or b) if I'm missing something in my attempts to get the bootloader unlocked.
Any thoughts or considerations would be greatly appreciated. I'm not sure what to try other than starting from scratch at this point.
Thanks!
I tried rooting. I checked with rootchecker so it didn't root. Update notification came and I clicked on update. The next screen I know said "your device is unlocked and can't be trusted" and after that a dead Android logo and "
error!" Message.
How did you try to root, and with what versions of what software? Did you follow the tutorials here, there are specific ways to go about rooting this device...
Hi everyone,
As title says, I'm facing difficulties in the unlocking procedure. The main error I get is the "Device not bound" at 99%.
Anyway, when I try to bind the device (which I already did before the procedure and waited for 72h) it asks me to accept permissions every time and, when the operation is (successfully) completed, the option to bind account is still "clickable" like i didn't bind it, and the operation can be repeated infinite times, which seems strange to me (look at the screenshot)
Plus, even though the "Find Device" option is enabled, on i.mi.com the device shows as offline.
Further, sometimes the device exits automatically from Fastboot mode or, at times, isn't recognized by the pc (this is a different problem but I thought it was worth to share it).
Thank you in advance for any help, I'm pretty desperate at this point.
Howdy,
I've used the Tab A for a couple of months now as literally a daily driver, since I modified it to fit into the multimedia slot in my car. It was rooted, had TWRP and even Viper4Android on it.
Long story short:
Since it's laggy I thought to test project Treble on it, since it's supported.
I wiped the tablet with TWRP and installed arm64 A/B (since it's Android 10) and it wouldn't boot anymore. It showed "Samsung Galaxy Tab A", shut off, vibrated and repeat. Also tried "Only A". Same result.
I thought to install it via fastboot. Since TWRP effectively replaced Fastbook afaik, I tried to flash the original "BL" downloaded form sammobile for this exact model. Flashed it, it succeeded and then...
It turns on with a blue screen that essentially says "This phone has been modified and is locked" with red letters on top stating "SECURE CHECK FAIL: recovery.img"
I can't get into download, it always jumps to this message. I tried all possible combinations, plugged the tablet into my pc while holding down buttons - nothing.
If I hold the pwr+down for circa 10-15 seconds while in this screen, it reboots and goes to a slightly different message stating: "SECURE CHECK FAIL: boot.img"
My PC doesn't recognize any USB devices, not even in the device manager.
What should I do? Any help would be greatly appreciated.
(I guess no music on the daily commute tomorrow lol)
Tried a Samsung JIG adapter. Still no success
Finally good news!
I tried it again with new combinations.
Turns out, if you hold all three buttons (pwr, down and up) eventually DOWNLOAD mode appears.
Worked here and am flashing stock now.
For rooting on latest bootloader (Rev:4, U4) which is the one you've installed already, you must purchase a subscription on this page and download that file for root:
https://support.halabtech.com/index.php?a=downloads&b=file&id=452768
As you described, it seem that you updated the bootloader and there's no way to get back at Rev:3 U3 bootloader, having the same trouble in rooting terms, I just hope a developer or an advance user that have a subscription in such page can help us and share the file that is on that page
