I do believe you have your phones confused. The Honor View 20 is the international version of the Honor V20 which was only announced in China last month, December 26, 2018. The international release of this phone is not until January 22, 2019. So Saturday's event really is a preview event. I am looking forward to seeing this phone because I really want to see what it is capable of photo wise with the new 48MP 1/2" Sony sensor.
[Honor View 20 Guides, News, & Discussion] MervinsOnlineID:
I got chosen to have the "chance" to join the event but I still haven't heard anything back from the Honor team after giving my information. Did they announce the final winners?
[Honor View 20 Guides, News, & Discussion] Rikiaic:
I was chosen n will be attending tomorrow. Very excited.
[Honor View 20 Guides, News, & Discussion] pdanielf:
Thanks for the Event and Invitation

I want to say thank you to Honor International, TK Bay, and xdadevelopers for putting on this event.

TK was a great host. The Honor View 20 models really have to be seen in person in order to properly appreciate their beauty.

The way the backs reflect light and react to even the slightest changes in angle and light intensity make them almost seem alive. I took a few photos as I tried to capture this light/color/patterns interaction.

I wanted to post images, but have not posted 10 posts yet.

The 48MP Sony sensor and the camera seem very versatile and impressive. The View 20 itself is very comfortable to hold and is no larger then my Mate 10 Pro while having a noticeably larger screen.

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?
[Xiaomi Mi A1 Questions & Answers] laugeek57:
Same here :(

i can flash with edl mode

flash nougat rom stock for oem unlock

flash twrp ok

flash rom black screen:crying:
[Xiaomi Mi A1 Questions & Answers] XtraWater:
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....

[Xiaomi Mi A1 Questions & Answers] XtraWater:
Thank you. I'll try it again. I also got bootloops, but the screen never turned on. As mentioed above, I was even able to install TWRP. And it booted into TWRP. But without a screen....

Thank you. I installed december rom. But screen is still black. Probably hardware defect.
[Xiaomi Mi A1 Questions & Answers] samuro625:
What ROM do you install through the TWRP? Have you tried only to install a rom, without Magisk or GAPPS and wait if it boots properly?
[Xiaomi Mi A1 Questions & Answers] XtraWater:
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.
[Xiaomi Mi A1 Questions & Answers] samuro625:
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"

For now these files are not useful, but do not erase them.
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Ok, I did shorten the folder and file. The process flash_all.bat by itself was successful and I guess the phone rebooted. But still no screen. Still dark.

You mentioned to install a Nougat custom rom. Would you suggest a particular one?
[Xiaomi Mi A1 Questions & Answers] samuro625:
I have a question: what images are seen on the screen? The logos of Xiaomi, the TWRP, others?

Anyone who is allowed to install by TWRP, following the developer's instructions.
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Nothing. Absolute nothing. Even no LED when charging. The screen is just dead.
[Xiaomi Mi A1 Questions & Answers] samuro625:
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.
[Xiaomi Mi A1 Questions & Answers] XtraWater:
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.
[Xiaomi Mi A1 Questions & Answers] XtraWater:
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.
[Xiaomi Mi A1 Questions & Answers] samuro625:
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 :)
[Xiaomi Mi A1 Questions & Answers] jack_21:
Boot.emcc.win isn't a Fastboot valid image!

.win is a TWRP format

How was possible to flash it?

I entered fastboot with Power and - Vol

then fastboot boot boot.emmc.win

Phone reboots/starts. Do you know a file which I should flash with fastboot ?

Inside of .win there must be something

No, I changed name to boot.emmc.win.rar but winrar don't know what to do with it.

I wonder if that something has to do with Slot a or b.

I tried fastboot flash boot boot.emmc.win

Answer: FAILED (remote: partition table doesn't exist)
[Xiaomi Mi A1 Questions & Answers] jack_21:
Because you have boot_a and boot_b

But I don't suggest you to flash that file
[Xiaomi Mi A1 Questions & Answers] XtraWater:
However, after fastboot boot boot.emmc.win

the phone boots. But after a restart it does nothing. Whatever is within boot.emmc.win, it leads to boot the phone, even without screen. I came to the pint where I could select the wifi network. But...well...

May be the screen turns on when I could use a boot.emmc.win from nougat. Is it actually a boot.img?
[Xiaomi Mi A1 Questions & Answers] jack_21:
Yes it should

But you have also aboot (apps_boot_mmc.bin) if I remember correctly

Maybe you can try flash that also

Which firmware were you using before the disaster?
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Thank you. All the aboot.img I got came with adb tools. Regarding to the emc file, actually I can only boot from it, but not flash.

The last os which worked was Resurrection remix. Latest final.
[Xiaomi Mi A1 Questions & Answers] jack_21:
It should came from the rom package

Did you tried to flash latest Pie?

https://mega.nz/#!l8dy1AiA!cbc6iiLjsTCLIB8vVn_O7mIZ3AjaUAtVlyBfhrJSI-0
[Xiaomi Mi A1 Questions & Answers] XtraWater:
I had that thought. But I found only OTA versions. Not sure what to do withe them.

I did the official pie update but went back to Resurrection remix oreo 8.1 which worked. Till I figured out that there was no audio on the dialer / phone app. Since I couldn't found a solution I flashed back my twrp pie backup. Phone worked and tried rr again from new. Same issue. Then I flashed latest official stock rom, based on oreo 8.1. Since then, screen won't turn on.

I'll be in 5 minutes at my pc and check your file.
[Xiaomi Mi A1 Questions & Answers] luxerinolt:
Same thing here. I can boot into EDL, boot into fastboot, but NOTHING shows on the screen. I can boot to twrp via fastboot commands but it shows nothing, flashing any official software doesnt help, too.

Just FYI, all of this happened after flashing official pie in TWRP.

By flashing anything past Nougat, the phone is in the vibration mode and i can't do anything, after flashing nougat, i can access fastboot, but nothing on the screen.

Once i managed to boot into twrp via fastboot, it showed only 10 gigs of storage in my computer. It didn't have any files or any traces of any ROM flashed, too.

I tried basically everything at this point - NOTHING HELPS. By this point i have already bought a new phone, but i am still looking for a solution so i can still have this device working.

I really hope someone finds a solution to this. I am willing to test things, roms, kernels, basically anyhing to recover the A1. If you have a possible solution, you can contact me on discord or telegram, since i am willing to try any solutions. My discord is Arnas#0001, Telegram - AArnas

For system a and b. However, the phone don't boot. I still can enter fastboot mode. But that's all.

[Xiaomi Mi A1 Questions & Answers] jack_21:
Invalid sparse is ok

Did you tried wipe data?

Something shows on screen?
[Xiaomi Mi A1 Questions & Answers] XtraWater:
The only thing I did was fastboot erase. But after the flashing process. The screen shows nothing. Also no LED lights or button backlight.

I'm not sure about wipe data. I can install TWRP but only get access by the ALL IN ONE TOOL. There is a button: Erase/ All Data / Decrypt Internal Storage.

In the zip file, there should be a "apps_boot" image or something similar

Then same thing but with "fastboot flash abootbak ...."

I got a aboot.img which I just flashed. And now, all the phone is doing is vibrating when on the USB cable or try to power on. The only way ( I know )to gain access again is with the test point method.
[Xiaomi Mi A1 Questions & Answers] jack_21:
So you flashed "aboot.img" using "aboot" and "abootbak" prefix and it only vibrates? No Qualcomm 9008 Preloader in Device Manager?

Can't enter in Fastboot mode now?
[Xiaomi Mi A1 Questions & Answers] XtraWater:
It seems, I missed the : Then same thing but with "fastboot flash abootbak ...."

Didn't use the abootbak.

I can't enter fastboot now. And no Qualcomm 9008 in device manager. To get back the Qualcom 9008, I need to enter edl mode by test point method.
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Yes, it vibrates only. Should I do the test point method?
[Xiaomi Mi A1 Questions & Answers] jack_21:
If you have a spare USB cable you can try to build an EDL cable

http://b.top4top.net/p_2699t7x1.png
[Xiaomi Mi A1 Questions & Answers] XtraWater:
I tried that earlier. That didn't work for me.
[Xiaomi Mi A1 Questions & Answers] jack_21:
Did you try to bridge the two wires and insert the cable into the phone, then wait for 8 second and release the bridge?
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Yes, but the cable now is messed up. Don't have another USB C cable. To do the testpoint method is easier for me. The warranty is gone anyway.
[Xiaomi Mi A1 Questions & Answers] jack_21:
Ok, try that and let us know!

If you gain access to Fastboot, you can try reflashing Pie rom and if that doesn't work, try last Oreo from en.miui.com (or Displax thread in Guide / News discussion)

But if you use the Oreo Rom, remember to edit the bat file that you will use in order to flash, removing "fastboot oem lock" related line
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Wouldn't reflash Pie bring the same result?

I tried to flash different versions of the official Oreo with the Mi Flash tool. There I can check if I want to clean or / and lock the bootloader. Not sure if I should use Mi Flash at all.
[Xiaomi Mi A1 Questions & Answers] jack_21:
Ah ok good

Well, maybe it's better to use MiFlash in edl mode
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Thanks. So you are saying that happen to other peoples too? I found some threads about black display, but everyone has different issues.
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Thank you jack_21. I'll try again to flash Pie and I'll post it here. Some further steps I should try after Pie is flashed?

For now I need a break :)

But it actually you don't think it's a hardware fault. That gives me some hope ;)
[Xiaomi Mi A1 Questions & Answers] jack_21:
We hope that!

Well I don't know if some additional step may help

I think it's better to evaluate next move after regain fastboot access
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Hello

I did the test point method and wanted flash the latest fastboot stock oreo from https://xiaomifirmware.com/roms/download-official-roms-xiaomi-mi-a1/ (Version 9.6.8.0) But it seems, this isn't a fastboot image, even it's mentioned. It's rather for twrp.

Instead I flashed Android 8.1.0 Oreo (images_V9.6.7.0.ODHMIFE). With that, again, Phone only vibrates. Nothing else.

Then I flashed version 7.8.23 nougat. So, now I can get in fastboot again.

I'm now a bit confused about your instruction to install Pie:: 'In the zip file, there should be a "apps_boot" image or something similar

This file wasn't in the flashing script, but you can try using command fastboot flash aboot images\apps_boot.img(or how it is called, maybe .bin)

Then same thing but with "fastboot flash abootbak ...."'

Within the images folder is a aboot.img. and a boot.img. Nothing else looks similar to what you mentioned. In fastboot, last time I did:

fastboot flash images\aboot.img

that resulted in vibration.

Do I have to use:

fastboot flash images\abootbak

bak looks like a backup.
[Xiaomi Mi A1 Questions & Answers] jack_21:
Ok so let's sum up:

- You used testpoint method and you were able to flash a ROM

- Oreo ZIP from unofficial site "xiaomifirmware" was for TWRP and not for Fastboot

- You tried to flash Oreo "9.6.7.0" but the phone only vibrates and it's not working (and no "Volume down key" fastboot mode)

- Then you flashed Nougat " 7.8.23" and now you can enter Fastboot using volume down key

Do you know if phone starts with Nougat? Is the screen black or off?

BUT PLEASE

Never download firmware from unofficial sites, trust only en.miui.com or XDA (where others users can confirm if it's working or not!)

You can find the latest official version (Fastboot) from Xiaomi here: https://en.miui.com/download-333.html (for now it's Oreo V9.6.8.0.ODHMIFE, because Pie was withdrawn for bugs seems)

Or you can find OFFICIAL fastboot images here https://xdaforums.com/mi-a1/how-to/ota-xiaomi-mi-a1-ota-links-t3718542
[Xiaomi Mi A1 Questions & Answers] XtraWater:
Yes, your summary is correct. Nougat starts, LED turns on and the backlight of the navigation keys turn on. The screen is off. I don't turn on. When I tap on the screen, I can hear when I touch a button. Or when I press the power button, it makes the sound when the screen turns off. But Nougat starts only when I fastboot boot boot.img or boot.emmc.win

The Nougat version is the only one which gives the phone some live. Fasboot is working.

I just downloading the stable version from https://en.miui.com/download-333.html

Most likely it will end up in vibration mode.......
[Xiaomi Mi A1 Questions & Answers] XtraWater:
I just installed TWRP. Booting to recovery shows me the phone in internetx explorer. Internal memory is 9GB. It should be much bigger. I tried to do screenshots with the all in one tool. It does create a folder named Screenshots_tool, but the folder is empty. I hoped to recover a TWRP backup.
[Xiaomi Mi A1 Questions & Answers] jack_21:
Well you can try to use EDL+QFIL Tool with the latest package you just download from MIUI official site

It will restore your partition as out of factory

Here on XDA they say download the latest version 2.7. But is still the same 2.0.1.1

Yes, because you must read the version number from QPST Configuration and not from the single tool (like QFIL in this case) :P
