Unbrick Mediapad t2 BGO-DL09 - Android Q&A, Help & Troubleshooting

Hello guys!
I am trying to unbrick this device but no success for now, no dload, no fastboot, no recovery, not recognized by PC, just image "your device failed to pass verification and can't be trusted" and no reaction on any buttons.
Does anybody know how to unbrick it?

@Maxnrg
Such error messages typically addionally shows "Visit this link on another device: g.co/XYZ" for example what leads to Google's help center.
Have you already visited?

Help my honor 8x bricked

My device died when I tried to install Pie Update by HiSuite and FirmwareFinder the message says "your device has loaded a different operating system"
I tried to install stock firmware by " dload " but i failed > This release is not compatible with the current version Please install the correct version
How can I restore my phone?
please help
Anything new?
Hello! Have you ever found a way to sort it out? same situation here.. I'd even contacted DC-Unlocker team and they said there's no plan for this model anytime soon!!
Seems to me that the only way to unbrick this phone is to purchase a bootloader and an FRP unlocking codes, that's frustrating because it's ridiculously expensive!!

Hello, can you explain how to make it work? Even dload method doesn’t seem to work for me cause I get the ‘failed to install’ message (instead of saying that I’m on a different version or so)!! dload method never worked for me it’s like I had no sdcard inserted.
I would like to get a detailed tutorial since I’ve never had ‘dload’ method to work, I think I am missing something!
Thank you

Flashing stock ROM for Mi A3 from EDL mode

Hi,
The Xiaomi Mi A3 is an Android One phone, is an authorized Xiaomi account necessary to flash the official ROM from EDL mode when the bootloader is locked?
The Mi A1 and A2 / Lite phones also Android One, don't require an authorized account in the same case, what's the difference with the Mi A3, perhaps the elf programmer file?

go to Fastboot mode & unlock
go to EDL mode using command :
Code:
fastboot flashing unlock
fastboot flashing critical_unlock
fastboot oem edl
My phone went into bootloop without any hacking/modding. I ended up EDL but whenever I flash I get a unauthorized from the flash tool.

Same thing happened to me, you need an authorized Mi account to flash in EDL mode. I had to connect remotely to someone who had an authorized Mi account to unbrick it.

hello.
if you were so kind to provide who was your contact? i have the same error and like to unbrick it too.
it just boot to fastboot mode (the one with the rabbit and the android).
thanks in advance for your comments.
Hi, I am facing similar issue as my phone is also in the fastboot mode.
Xiaomi is telling to contact their service center but in the current scenario, this is not possible.
Can you suggest how to get some OS installed so that my phone is unbricked.

you can check this tool, is very effective.

Hi,
Thanks for the reply.
The problem is, i had never enable USB debugging. So no tool seems to be working.
The issue occured when i received an OTA update for Android 10 and my phone went into restart mode.
There it got stuck on the fastboot screen.
I dont know if this occured due to it having being connected to charger at that point of time.
Anyways, is there any alternate option considering the USB debugging is not enabled and neither is the bootloader unlocked.

Realme 7 RMX2155 SP Flash Tool error

I have a problem when unlocking bootloader in my Realme 7 RMX2155 device, i did all exactly like in guide, and i have an error like this:

See the message I replied to you with in PMs. Lemme know if it helps.
Did you install the python application properly? Without running the flash toll, you will press and hold the volume down and volume up keys of the phone until the download is complete..This is a sequential process, if you miss one, you will not get the result...Finally, on a PC with win 10 installed, the field is very difficult, it causes problems in loading inf files, and you will disable signatures on it. I am writing from the translation, the explanation may be broken

Redo the Brom steps. It's either you did not pass BROM or pass with error msg ( if it is, give ss of the error msg )

Question MSM Download tool for unlocked version

Please upload this tool if you have it so i can fix my phone .. at this point t-mobile, metro pcs and god knows what they all were able not only to fix their phone but install the unlocked rom without the bloatware .. Honestly i don't get why OP refuses to release this .. or maybe they have but its not posted here ..
So if you bought your phone from oneplus.com and have the unbricking tool .. please upload it or tell me how you managed to fix your phone
Contact OnePlus support, and request a remote session to repair your phone.
If they set one up, they'll send you a link to download the MSMDownload Tools ahead of time.
So far everyone with unlocked version has been told to mail their phone in, rather than doing the remote session. Once someone gets the remote session, they'll be able to upload the MSMDownload Tools.

already went thru that and instead of sending my phone in chose to wait for the tool.. looks like i made a huge mistake and now is too late to send it in ... but thanks for suggesting
Also waiting for an ops for the unlocked variant - I have a theory that converts between variants without unlocking BL, but without the ops it can't be verified.
I believe One Plus is not releasing their MSM tool specifically because it could be used to convert variants to unlocked / retail. They have refused multiple board members, myself included, to utilize the tool to remotely fix broken devices.
Dimitrimem, check the unbrick thread for my instructions on how to fix phones using fastboot and a super.img or fastbootd and the OTA.
Un-bricking my Nord N200
Don't ask me why, but I tried to upload a GSI using fastboot to my N200. And that didn't work. So I then read online about other people getting the same error I had, and their fix was deleting the "product" partition and erasing the system...

Bootloader is locked so fastboot is not an option ..
Do you have the unlock code bin file?
If so do the following, because booting in fastboot itself will give you an error saying you cannot unlock the bootloader, you most boot into recovery, fastboot is not recovery it's considered the master recovery Incase if the Android recovery fails or you flashed the wrong file to the wrong partition.

I don't
You'll need to give that information. Check the box, your serial number should be on it.

The only thing I have from my mail with oneplus is the IMEI number from the form they made me fill in for the remote session only that later on they told me they don't have the files(msm) for my phone
If IMEI and serial number are the same let me know and I'll post thst here
The most you could do is get the unlock code bin. Then wait 7 days for a reply, flash your device with the TMobile msm, and then follow the TMobile to oem, that should do it.
If you need to reach me for stuff like this, I am available on discord via the xda,

From the screen itself. No it boots back to the error .. but I was able to get into recovery by pressing volume up and down

I have the fully paid variant.. so I don't need the unlock code... That's t-mobile.. my bootloader is locked or OEM is locked
Your phone comes preloaded with an emergency boot chip called Qualcomm download mode. Use the TMobile msm tool to flash your device back to factory, then you can essentially do what you need. To get back to oem.
I keep forgetting to quote reply I hate this lol.

Question Edl Authentication error

I hardbricked my N20 by installing CPH2459 files on GN2200. I believe I didn't put dm-verity cmd in my vbmeta flash line on fatsboot.
I want to point out that if you hard brick, EDL has authentication, so there is no way to "fix" the phone and get fastboot back to recovery it all. I have spent 2-3 days on it now. Probably will see if Oneplus can rma/flash it. I have tried Qfil, MSM Download, Rombox (the screenshot on XDA show N20 but the actual application doesn't have it).
If anybody has a solution please let do me know otherwise just letting you know EDL has authentication won't let you flash thru firehose.
message from EDl using Qfil:
INFO: TARGET SAID: 'INFO: VIP is enabled, receiving the signed table of size 8192'

I bricked my MI A3 a few years back by flashing a ROM to the wrong slot (a/b)... I didn't know any better. I had to take off the glass back and jump it into EDL mode with a staple. It was tricky as you had to tap the jumper pads at the precise moment to actually get it into EDL mode. Someone on here PM'd me and I had to connect remotely with a person in Russia (seemed shady) with an authorized Xiaomi account to flash it back to stock ROM. $28 I think I paid, fortunately the guy was legit.

OnePlus will return you to stock remotely if it becomes beyond repair.
Also there are a few adb and fastboot capable apks but I am fairly certain it would violate the forums rules to name them.

I wouldn't know how, I'm just able to follow guides on how to root, flash ROMS etc. I have little understanding about that.
