Unusable A2017G - ZTE Axon 7 Questions & Answers

So i have this A2017G owned by a cousin of mine. He had never tempered with anything except updating OTAs from the settings app. Meaning Stock everything and BL locked. Now, all of a sudden his device lags a lot (after the N-B06 update). When booting the device the boot animation lags like crazy. And it almost never gets past the boot animation (always restarts at Axon 7). The times it does reach past the boot screen, the device hangs after a minute or so and restarts.
Things that i have tried:
# Factory resetting through stock recovery.
# Downloading update.zips from ZTE and trying SD Card update trough stock recovery. Which always fails saying Signature verification failed.
# Booted to factory test mode and tried adb devices on cmd. Nothing comes up as there is no new device on the device manager. Also no sound.
# Booted to EDL mode and flashed N-B06 from this post: https://forum.xda-developers.com/axon-7/how-to/guide-ztea2017v2-0-0b08-t3658636
Nothing helped. Same old lags. And of course, the device is unusable.
What to do? Suggestions?

Get a new phone. Unfortunately I think it's some hardware that is broken. But in case it's not try to flash b05 instead?

I don't see anything else you could do since adb doesn't seems to work. I'd just RMA it with the warranty still being in effect. And if it was purchased trough amazon you'll probably just get a new one ! (that's what happened to me last time).

Did you try downgrading through EDL? I'll post the link to MM B10 for you to install through EDL, see if that helps. I seriously doubt that it's a hardware issue since it would not even boot if that was the case (take the Nexus 6P and 5X as an example: big cores busted and the phones wouldn't get past the boot logo).
Don't unlock the bootloader if you can't fix it, it'd make matters worse if LOS-based ROMs didn't work.
Edit: Here are a couple of links for B10 from 4pda. should be the same file:

I have tried this EDL package as well. Most of the time it says can not found programmer file. Only once it said can not find hello packet, reset status. That also ended up in error.
The N-B06 EDL package flashes fine. But the problem still persists.
I have also tried replacing N-B06 recovery.img with TWRP recovery.img and flashed it. But that just bricks the recovery.
Currently the 2 EDL packages i know are these two. N-B06 and MM-B10 for the G. The N one works fine while the MM one doesn't. Do u have any other EDL packages?
I too think it's a software problem since he has never dropped the phone and only used it for 2 months.

I think something is wrong with the hardware. I had a similar problem as u with my last phone a honor 8, it frozed up and it was nothing I couldnt do other than go back to the store with it. I got a new one.

I got that package from 4pda. if you go to the 4th category brick repair manual, then enter the link that says "Qualcomm drivers and MiFlash" it will redirect you to 4pda. no need to translate: just open the spoilers (I think it's the 2nd) and you'll find all of the images. You obviously have to use the A2017G ones. there's B10, i think B11, B05, B06 and maybe another N package too
The thing is that it'd be best if you could downgrade to Marshmallow, as that would probably do some other stuff that N packages don't do.

Do you have an external SD card plugged in? Try to use without external sd, i already had lags because of a defective sd card (that couldnt be rescued nor reformatted )

I was gonna suggest that, but a read-only SD card wouldn't provoke that. I had one that got read-only after using it as swap for a long time, and you would only notice in twrp (booted in ~2 minutes). If he was able to try to install a system update through the recovery, he was able to write to the SD card --> it's not dead

It lags the same. Regardless a sd card is inserted or not.

Thank you for mentioning there is EDL packages in 4pda. I just tried the packages that are available for the G variant on 4pda. But the problem still persists.
I was thinking that too. Trying to downgrade through EDL. But so far i've found only one MM so far, B10. But that ends up in error during flashing process.
Is there any way to install TWRP through EDL without unlocking bootloader? Also, is there any way to unlock BL without adb? If i could at least unlock the BL, i could flash twrp through EDL. There are EDL packages available for flashing TWRP.
Thanks.

Mabey but I think as in my case that something has happened with the hardware. I think it is a hardware's fault that has come up to the surface when he updated the phone like it did 2 me. But hey, it's just my theory.

The problem is axon 7 is not available in our country. If he has to rma it then he has to send it to a relative in Sweden. Then the relative can do that for him. That's why he asked me to do what i can to revive the phone. RMA is the last resort for him.
Now, i guess i will give up and tell him i did everything i could.
Anyways, thank you all for helping.

Pixel XL bricked by switching to Slot B in TWRP No rom, bootloader, recovery,fastboot

Hey,
I just wanted to inform you about an issue that happens in TWRP. I just bricked my Pixel by switching to slot B without flashing a bootloader in slot B. I think TWRP should inform the user that rebooting will brick the device. What are your thought on that? It could be done similar to how TWRP informs the user to install supersu if the phone isnt rooted.
This would be really helpful as it would prevent many people like myself from bricking their phones.
Now if I connect my pixel it only shows Qualcomm HS-USB Diagnostics 900E (COM3). No bootloader, fastboot, or recovery is present.
Here are a coupe of links of other people that did the same thing:
https://productforums.google.com/forum/#!topic/phone-by-google/sXjCoQ8glac
http://forum.xda-developers.com/pixel-xl/help/pixelxl-bricked-t3517310
Thanks!
Edit
I contacted the devolper of TWRP and he says that it should have boot loader regardless.
Here is the history: At work 3pm, froze Android system apk and some other telephone apps to troubleshoot something, I know I shouldn't do this. Resulted into boot loop. Go into twrp recovery and wipe data. It boots up fine and I see it downloading updates but it never goes through, I attempt to go back to recovery and apparently it's back to the stock recovery even though I originally had TWRP rc1.
I get home at 7 pm, I want to install TWRP rc1 so I send the command to boot into TWRP and then I install the zip, then I install sr5 SuperSU. I change to slot b and it's been bricked since.
It arrived November patch and it stayed like that since I was rooted. It attempted to install 7.1.1 but it returns installation problem. I think the bootloader was removed because of the failed update.
Your in download mode. I had this happen once on my Nexus 7. I held power for 90 seconds and it went back to bootloader. However I dont know about the pixel. Its still a new and uncharted device.
You also have to realize TWRP is in an unstable stage. You really should not flash anything until its in final release mode. I know I know... Hindsight is 20/20.
If you have insurance you could get it replaced.
Good luck.
sorry to hear dude..

Does anyone have an understanding about how something like this could potentially happen? Do these phones ship without information on the second slot? After my phone OTA updated, I switched slots without issue back to the previous version by following the information from Android Police. I'm not clear on what exactly would need to happen for the noted situation, and how someone could potentially get into a similar situation, unless the phone ships without information on the second slot. Switching slots worked without issue the times I tried it, but my phone had been through a typical OTA update before switching slots, so there was definitely information on both slots when I tried it.
Just an FYI: I am running Slot B on my device. Never tried Slot A. Just an FYI

Same, mine is on slot B. Dunno if it came that way, but it is only two days old. I let it take the OTA then flashed Francos kernel and then booted the root su image.
I really regret not watching more closely how all of impacted which slot it was on.

Everytime you get OTA update you will switch slots. If you update via flashall it will say on the same slot.
This mode can't be a complete brick but it doesn't look like anyone has a solution yet. Maybe we will need some HTC tool?
Also when you root or modify you take responsibility for anything that happens. There is always a chance of a brick. At least Google will still probably warranty these devices.

Updated op with more info
I installed TWRP while in the car riding with my girlfriend. I had some issues with the mobile radio showing no SIM card. Due to my limited options, I tried switching rom slots. It booted into the old software and said there was an update etc. I don't think switching rom slots leads to bricking if no other mods were done.

were you rooted because I had an ota in process wich failed while I was rooted which I think was the cause of the issue.
I kind of had the impression none of the stuff we're flashing is the bootloader itself. Isn't the bootloader the Android equivalent of Windows BIOS? Doesn't the bootloader load the boot image? Then the boot image mounts the system partition? So how could anything we're flashing cripple the bootloader?

Bump
The problem is that the phone ships with an empty slot. If you try to boot it your permanently bricked do to having no bootloader on that slot. Once you take an OTA both slots have data and you're safe.

There is only one bootloader though so that's the confusing part. Still not sure how some people bricked completely. The bootloader is the first thing to load and tells the phone which slot to boot. Each slot does have its own boot, system, and vendor though. Been discussing this a lot on some other threads and there is still no answer has to what some of these people did internally that messed up their phones

Failed bootloader flash? The Google .IMG files contain bootloader's.
EDIT I do believe the flash_all.sh flashes the bootloader
So you cant even run ADB commands ( a.k.a Bootloader / Recovery mode ), its a hard brick or soft ?
Does your PC detect the device when its on and connected via USB ?
Why did you switch slots in the first place ? if your taking an OTA on a rooted device with SU an OTA wont even apply via TWRP, you have to manually flash with the flash-all.bat script or part by part and the A / B boot slots are handles by the updates so you don't accidentally boot with a slot with no bootloader.
There is no need to swap A / B manually and if your going to flash and want to play with the A / B slots you should at least flash the partitions first but hindsight is a wonderful thing.
Aboot here might be your friend, but as this device is still quite new to many devs and or the tools might not be publicly available . . .

Encryption unsuccessful

Hello... Try sideloading a full OTA of your choice from here: https://developers.google.com/android/ota#angler
It needs to be newer than the installed version. Not sure it will solve your issue though. Maybe someone else will chime in with a better solution...
If nothing works, RMA your device.
Good luck...
Thanks for the advice.
I tried to manually flash OTA but it falied because of the locked bootloader.
I am not sure if there is anyone could point me to do it via ADB. I tried using ADB but the phone is not recognized by my computer yet.

Hey...
Reboot into Bootloader. Select recovery mode with the volume rocker and press power.
Once you see the Android guy laying down with his belly opened, press power and tap volume up once.
On the menu select: apply update from ADB
From here type in a command prompt:
adb sideload "name of the full OTA zip you downloaded without quote"
Supposing you have prior knowledge with ADB. Let me know if something is not clear here...
Good luck...
I finally get ADB recognized Nexus 6p. But the ota stop flash at 46%. failed to read command: No error.

Probably so. There is one guy who found a 6P with a shattered screen for sale and paid a local repair shop to have the motherboard swapped out. Claims it cost him less than USD $100 but he is in South Korea. You're probably better off cutting your losses and finding another phone... after Huawei tells you NO three times.

posted it on craigslist now.
( I noticed that you are in the Woodlands area. I missed the time when I am in Houston. One of the best memories)
just a follow-up to somebody might see encounter the same thing. I was not able to fix the phone.
With a locked bootloader and "encryption unsuccessful" page, you might try warranty first. If that does not work, you might want to take rescue OTA from google and flash it in recovery via " install update via ADB".
Please be aware that rescue OTA is different from system image and should be flash via ADB in recovery.
Good luck.

Here are Rescue OTA. One would need to flash it with ADB in recovery. https://developers.google.com/android/ota
The following one is firmware/factory image. One would need to flash it with fastboot while in bootloader mode : https://developers.google.com/android/images
Use the correct zip file according to your flashing mode ( recovery or bootloader)

Hello,
I see nothing different than hmm an OTA here. I thought that was a "special" OTA, but no.

Hello!
I have the same "Encryption unsuccessful" issue. It happened many times recently. First I replaced the battery, because it produced early sudden shutdown at 30-40%, and could run only for a few hours from 100% to 40%.
The new battery is enough for 30-40 hours as I use it, and can operate the phone down to 1-2% before shutting down.
But if I have to restart the phone, the encryption unsuccessful problem still comes up randomly after battery replacement. I can restart several times without problem, then randomly just fails. Mostly after software updates I guess... I have stock firmware, stock rom, etc. the only thing was made that I have installed TWRP, and wiped user data. Hope that helps. Can it be the defect of the emmc ? If so, how shall I diagnose it?
I'm very newbie android user, I changed from Windows Phone ( ) only a few months ago...
The question is what could cause the Encryption unsuccessful error? It's interesting, that if I enter any random numbers as unlock code, the phone tells that it appears to be valid, but unfortunately cannot decrypt data.
So I would like only to disable forced encryption, maybe that helps. Could someone point me to the right direction about what exactly should I do? Is it enough to flash a modded kernel to disable encryption? I don't want to root, or experiment with custom roms and I would stick to the factory firmware as much as I can, but without encryption of corse...
thanks!

But if I have to restart the phone, the encryption unsuccessful problem still comes up randomly after battery replacement. I can restart several times without problem, then randomly just fails. Mostly after software updates I guess... I have stock firmware, stock rom, etc. the only thing was made that I have installed TWRP, and wiped user data. Hope that helps. Can it be the defect of the emmc ? If so, how shall I diagnose it?
I'm very newbie android user, I changed from Windows Phone ( ) only a few months ago...
The question is what could cause the Encryption unsuccessful error? It's interesting, that if I enter any random numbers as unlock code, the phone tells that it appears to be valid, but unfortunately cannot decrypt data.
So I would like only to disable forced encryption, maybe that helps. Could someone point me to the right direction about what exactly should I do? Is it enough to flash a modded kernel to disable encryption? I don't want to root, or experiment with custom roms and I would stick to the factory firmware as much as I can, but without encryption of corse...
thanks!

Same. The data decryption being unsuccessful happened to me as well on stock oreo 8.1.0. not rooted
Anyone know how to fix it and doesn't happen again?
Thanks

Screen Not Responsive After Flash ..... +

Hey,
I've been on quite a journey since I attempted to flash the Treble rom for newbies. My phone eventually ended up as DFU'd but, I brought it back to life after a following the DFU Unbrick - Disassembly guide. After doing this, the screen was not responsive to touch at all at the Welcome screen of the EDU ROM. So, my adventure continued as I took the phone apart several times again to make certain things were connected, not damaged, etc..
After flashing TWRP I concluded the screen itself must be fine because I could use TWRP using the screen/touch. I have since tried flashing several different roms, tried many combos of unlocking the bootloader (again, because I assume it was already unlocked due to the bootloader warning screen of can not check for corruption message), tried flashing bootstack and the stock rom from DrakenFX. Used MiFlash, EDM Tool to flash various items.
Each time and currently, when it boots to the Welcome screen it does not respond to touch.
Can anyone please help me with this?
Thank you!
I remember this happened to me some years ago with a different phone, and it was a bad flash.
I resolved it by flashing the stock firmware again.
What did you flash with MiFlash? Stock firmware untouched? You must do this, try with B35 untouched. Don't flash stuff with TWRP.
Untouched? Is there anything on here like that?

Those are "untouched" system images. Replace recovery.img with a proper TWRP version before flashing:

Yeah, unfortunately the very first link (since I am in the USA and have a U version) is the very stock EDL version I used with MiFlash rightg after I was successful getting the phone out of DFU. I have tried flashing it twice after and still nothing.
Thank you for helping!!!

Sad to hear that... Maybe you can try again? Who knows, with a little bit of luck...
Or try another version, like this one:
https://www.androidfilehost.com/?fid=890129502657579386
btw, did you try every single spot in your screen while in TWRP? Maybe some pins in the connector are broken and some parts work and others doesn't?
And for the sake of it, you could try discharging your battery completely.
Last thing I can think of... is to restore the stock recovery and apply the official update via sdcard:

Yeah, the entire screen works perfectly in TWRP. I disassembled it several times before when I thought I may have put it back together wrong or damaged something so, the battery was removed those several times therefore, no power.
I'll try the stock above. I'm actually trying another stock rom atm --- flashing from sdcard

Well, EUREKA! I found I had saved the first files you were supposed to load when the Axon was first unlocked ( file name STEP_1_3-B20_FULL_OTA). Flashed it and the screen works fine. Now, I have to remember how to update it...lol I've unlocked the bootloader in Developer mode and I should be on my way..... fingers crossed.

Strange.
Nevertheless, congratulations. Happy for you.
Well, it's great that I now know the screen/hardware is fine but, I am unable to get any further than version B20. OTA doesn't work, the other files to flash (STEP_4-B20_to_B27 and STEP_5-B27_to_B29) won't flash and get aborted due to it expecting a certain version. I've tried DrakenFX Bootstack and then Stock System and it boots to the Welcome screen but the screen is no longer responsive again.
I have been at this all day again and it's shaping up another all night too. I am so baffled!
Restore to stock firmware your phone came shipped with.After that update trough ota or sd card package and maybe dont flash Treble again,its broken

i wish i had seen this sooner, because i have this same exact problem on one of my boards. it will update perfectly to any of the MM sd card update files (see rootjunkys bl unlock video, thanks @Tomsgt) but the board/phone will not retain touch functionality on anything higher than mm b29. i had lost my imei on that board, and actually swapped to another one despite eventually regaining it simply bc i wanted to be on Oreo ROMs. if you find a fix, id love to know about it. i flashed and reflashed every update, sd card versions, edl versions, and OTA updates to no avail. Nougat or above, touchscreen didnt work... mine was a gold a2017u. good luck, man. im glad im not crazy.
Sorry to bump an old(er) thread I started. I wanted to ask if anyone has found a solution to this issue yet?
I have since tried updating using OTA to Nougat and the screen doesn't respond so, I had to flash back to Marshmallow B29. Thank you to anyone who might have an idea!

[SOLVED] Cascading failures leading to bootloop and softbrick

Hello all. I am about done with this phone. Let me give you a quick timeline.
I had a bootloader error, so I flashed the NPN25.137-35 images to get it working
I used it for about 1 week, installing all of the OTA security updates
One morning, my phone had restarted (I know because "You must enter your pattern after a restart")
Over the course of this day, google apps starting force closing and opening some of them would soft reboot the phone.
The next day, random apps were doing it too
Finally, after one crash, the OS never came back up, it was bootlooping
Upon a hard restart, the phone only boots into bootloader.
This is where I am now. I have downloaded NPN...35-5, NPNS...93-10, and NPNS...92.14. Unfortunately, trying to flash any of these give me a "prevaildation failed security update downgrade" error on every partition I try to flash. The phone just bootloops when I try to restart it.
Things I have tried:
Using fastboot to manually install one of the 3 packages mentioned above.
Using a toolkit to automate the install of the 3 packages.
Using Motorola Device Manager (Never got it to launch)
Flashing the blankflash bin (No usable image file found)
Android OEM unlock setting was not set before this crash, so I cannot unlock the bootloader.
Praying to various deities.
Unzipping the packages, editing the *info.txt file into androidinfo.txt and rezipping to use as an update package (Invalid info.txt error)
I have no idea what to do next. I find it frustrating that Motorola doesn't differentiate between 32GB, 64GB, Amazon ads, no amazon ads, US, EU, or indian variant in it's model numbers! Everything is just "XT1687" and none of the update files are named with words, so knowing what the hell I'm flashing is impossible.
So, frustrations aside, does anyone have any suggestions as to how I can get this phone working again. On a side note, the only thing that I can think of that would cause such a cascading failure from Stock OS is RAM or Storage corruption / failing. Any thoughts on that as well?
=~=~=~=~= SOLUTION FOUND =~=~=~=~=
This may not be a good solution for anyone else that has this issue, but recently Oreo came out and the OTA update was captured. I was able to flash the new OTA because it had a higher security level and at least got the phone bootable.
Do you know what software channel you were on? E.g. retus, retla, etc? If your phone was completely up to date with the OTA, then you can't use a firmware version of less than 92-14 or 93-14. Whether or not you use 92 or 93 depends on the channel.
Locked bootloader limits other possibilities unfortunately.
Retus. I can't guarantee it, but that looks familiar to me, like I had seen it somewhere in the "about phone" section. Is there a released Stock image that has the current security patch? I can't find it on XDA and I'm not trusting androidfixfiles.info or a link in a youtube video.
93-14 hasn't been leaked yet. So you'll be stuck for now.

As a last resort you might try booting TWRP in fastboot mode, download and flash the TWRP flashable version of NPNS25.137-93-14. and see if that gets you back to a working phone. Just a suggestion. I don't know if it will boot when the bootloader is locked but it is worth a try.

I get that. What I am suggesting is not installing TWRP, but booting it from fastboot, if it is even possible. Given your results trying to flash a ROM I would say not. But what do you have to lose by trying?

I've tried that with a locked bootloader myself, it doesn't allow a non-signed image to boot. OP should give it a go as a 'hail Mary' attempt, but I wouldn't be holding my breath.
I've never heard of a phone that was fully stock with no mods or flashing ever done on it getting a bootloader error. The only bootloader error I am aware of is when the bootloader and ROM build are mismatched which doesn't happen unless the phone is being manually flashed. Was the phone on a custom ROM and you tried to return to full stock? Did you purchase the phone used?
If no to both exactly what did you see when you got the bootloader error? What was the message and what was the phone doing?
People who are on full stock with a locked bootloader don't usually flash system images so your story is a little hard for me to understand unless there is more to it. Normally a factory reset would be the logical solution when your phone is acting odd--flashing a system image seems pretty extreme and it sounds like flashing the wrong system image might be the cause of your current problems.

I agree. :good:
While my phone was wholly stock, I am not new to phone rooting or custom ROMS. I bought the phone from someone who was trying to unlock it. They screwed something up and couldn't get the phone to boot. I bought it, flashed the NPN25.137-35 image after reading plenty of XDA posts about it. This one was the Retus / North America stock image. Flashed using the suggested guidelines that are along the lines of "fb_oem_mode ... flash oem oem.bin ... flash partition sparsechunk1.img" (Something like that). That got it running and once booted, it had many OTAs update in quick succession. After about a week the phone started having trouble. Google apps would crash frequently, then non-google apps started crashing and restarting my phone. After one said restart, the phone would only bootloop. I tried rebooting into recovery to do a factory reset and got the bootloader instead. I can go take a look at the bootloader and see if it says it's secure / oem or what

Try flashing just the stock recovery, as it sounds like that is corrupt. Ideally you'd want to get a recovery that was the same build as you were on after all the OTAs had installed. At least you'd hope that that would give you the factory reset option.
If that doesn't work, there's fastboot commands to erase user data, cache, which would be pretty much what a factory reset would do. Hope you had your data backed up.
Oreo OTA came out recently. Someone grabbed the update file and uploaded it. I was able to flash it and get the phone to boot. The verdict is still out on if it'll be stable.

Hard brick Mi A1?

Hello
I decided to start from scratch and installed latest stock rom with mi flash. The tool reported successful but I ended up in a boot loop. Somehow it failed when the screen came up with 'data encryption....'. I flashed it again ad the phone only vibrated when power on. I hat to do the restore point method to gain EDL mode. I flashed an older firmware. Now the screen stays black. I'm able to boot into fastboot, unlock the bootloader and install TWRP. But the screen is just blank/black.
I have a feeling it haves something to do with emmc_appsboot.mbn or boot.emmc.win
When I flash boot.emmc.win with fastboot on Slot A (I tried both slots) at least the LED turns on when the device is plugged on a USB cable. But nothing more........
I still have my backups, created by TWRP. I don't know this is in some way helpful.
I find the tool TWRP Backup Tool. It seems I could restore a TWRP backup from there. But which file should I use? My backup is a folder. There isn't any .zip or .img file.
Some ideas?
Same here
i can flash with edl mode

can you do me a favour please? After the rom I flashed last night (yes, I guess it was a Nougat version) I was able to enter edl mode and unlock the bootloader. Today I tried other ROMs. Now, I forgot which Nougat version exactly worked for unlock boot loader. If you can post the exact version or a link would be great.
I don't think it's a hardware fault. I guess we need only the correct boot files. It should be possible to extract those files from a TWRP backup. But I can't find any hint how to do it.
If you find something that helps. please post it here. I'll do the same....

Yes, the bootloader is unlocked. I'm able to enter into fastboot. From there I can flash TWRP and boot into recovery. I installed even Magisk. It seems everything to work, but the screen. I was very careful when I did the testpoint method.
Here's the result of the fastboot oem device-info:
(bootloader) Device tampered: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
OKAY [ 0.047s]
Finished. Total time: 0.047s
Do you think there is still a chance to fix the device? I thought about to send the device back where I bought it. The device isn't even 2 week old. But I doubt the dealer will grant me warranty since I opened the device.
Edit: THe cellphone starts normally me thinks. If I want to boot into bootloader I have to press power and vol -
I run the TOOL ALL IN ONE which shows me immediately when a Fastboot device is detected.

After I was in bootloop (with screen) I wasn't able to unlock bootloader. So I used the Mi Flash tool. I tried different (at least 6 or 8 )versions from this site: https://xiaomifirmware.com/roms/download-official-roms-xiaomi-mi-a1/
After flashing the roms, the phone only vibrated when tried to boot. It repeatedly vibrated when connected to the USB cable and charger.
Only one rom allowed me to enter fastboot and unlock the bootloader. Android 7.1.2 Nougat (N2G47H.7.8.23) ( https://xiaomifirmware.com/download/5117/ )
That's the rom which is currently on my phone.
I tried once to install the latest Oreo 8.1 with TWRP. Since my screen is black, I used the TOOL ALL IN ONE. The flash process was successful. But then again only vibration when try to boot.
Actually, in all those versions GAPPS or Magisk isn't included.
Just to mention; my Mi A1 is a MDG2. Not sure if that matters.
Without the screen, I'm kinda limited regarding to TWRP.
EDIT: I never did a backup by ADB. But I did several with TWRP. I wanted to recover one of them. But methinks, that's not possible with the TOOL ALL IN ONE.
Edit 2: I also made a TWRP backup from the Stock Oreo 8.1 version. It was the state on which the phone was delivered. I only did installation wizard like login to google account.....
The folder contains files like data.ext4.win000, data.ext4.win001, system.ext4.win000, system.ext4.win001. But once again, I don't know if this is helpful in any way.

OK, we already know that it is with bootloader unlocked and in Nougat. That tells us 2 things: 1) It will not accept Stock Firmware until it blocks the bootloader and for now, that is not recommended. 2) You have to install a Nougat CustomROM, because to install Oreo you need to update the firmware.

Since the use of the AIO tool has not been effective, I would consider using the native firmware's own commands, especially flash_all.bat, which in theory leaves the cell phone as a factory and does not relock the bootloader.
Another aspect to keep in mind is that before decompressing the firmware file, rename it to a short one. It happened to me that a very long folder name was generated and the flashing was not completed.
Try this process with firmware N2G47H.7.8.23, using the instructions on the page that you mention, in the section "How to install Stock ROM (fastboot) on Xiaomi Mi A1"

So, in this case, there is physical damage that I can not deal with. You could try using the warranty, but you should trust that the marks on the screws are not noticed.

They will see it. I tried with a common screwdriver. Since this didn't work, I bought a kit.
Well, bad luck.
However, thank you very much for your effort. That was very kind.

A last question. If they replace the phone, I know, there chances are zero. Would I face the same issue if I want resurrection remix with the phone sound? Would I have to flash that modem.img?
If so, that's just not worth. It all started with that problem. Everything worked perfect but the phone.

Well, the truth, I never had any audio problem with calls with Resurrection Remix, and this rom I have used it in more than 6 phones of different manufacturers.
In my case, the problem of the calls was presented by flashing the modem of the version 8.1 of November, but downgrading to 8.0 was resolved.
Good luck with the cell phone, and it's a pity that it has been damaged.
It is advisable to learn to use the ADB and fastboot tools directly, rather than the AIOs.

Hello
I didn't give up so far. Something interesting happened.
I did the follow command: fastboot flash boot.emmc.win
The flash boot.emmc.win I extracted from my TWRP backup. Now, the phone rebooted and I hear a android notification. The charging LED is working too and the backlights of the buttons. When I touch the screen, the backlight of the buttons goes on. It looks like the phone is running. But, the screen is still off.
When I press the power button short, I hear the sound which indicates the screen goes off.
Tell me if I'm wrong, but with that behavior I think it isn't a hardware damage. Since still is Nougat installed, I might need a boot.emmc.win for Nougat?
We could be very close to fix the software.
EDIT: I used: fastboot boot boot.emmc.win
If I understand this correct, that way it is only temporary. So I tried:
fastboot flash boot_a boot.emmc.win
and
fastboot flash boot_b boot.emmc.win
With that, nothing happens. So, now again fastboot boot boot.emmc.win
Phone has restarted. I hear a sound. When touch the screen backligh of buttons goes on. I'm in a menu I guess. The installation wizard. I also hear the sound when I press something on the installation wizzard.
At least, that's new. Before there was nothing.
Edit 2: Might it be related to efs1.emmc.win and efs2.emmc.win ?
Edit 3: That's crazy. I touched the screen randomly and activated a 'Screen Reader' for blind people
