Hello. I Factory reset my Mi A3 while in my Google account not through recovery. Now when I boot the phone I get an error saying unable to connect to wifi when phone is connected to wifi and the when I try to add my Google account I get a message the The Google servers are unavailable and try again later. I did some looking and tried a few suggestions on line, about deleting Google app caches and delete account and add account. I deleted the phone in my Google account in my desktop and can't add it again, I turned off two step verification...it's seems like the phone isn't behaving at all right. I can get into the phone and a message will tell me to finish setting up and when I tap the message I go to the start up page. The phone isn't currently rooted but the bootloader is unlocked.
Thank you in advance for reading this far, please any help is appreciated.
I haven't experienced that problem myself, but if you have already factory reset your phone, then why not download the stock rom and flash it? That would reinstall your OS and may solve the problem. Do it from Android SDK platform-tools. You will need to boot your phone into fastboot mode.
Download the stock MIUI firmware fastboot image from: https://xiaomifirmwareupdater.com/miui/laurel/
Then follow the guide here: https://www.thecustomdroid.com/xiaomi-mi-a3-stock-firmware-guide/
Thank you for your reply. I was thinking about that and wasn't sure if it would help. I will try that and let you know how it goes.

Well I have gone from bad to worse. Now stuck on fastboot screen and bootloader locked. Ugh!
If you google "mi a3 stuck on fastboot screen etc" you should get a couple of suggestions. Can you boot into recovery? Press the power key and the vol. up key at the same time. Keep holding until phone restarts, then release the power key and wait for the Recovery menu screen to appear.
Also did you read the Important Note at the bottom of the instructions?
If the device fails to boot into the OS and keeps bootlooping, connect it to the PC while in fastboot mode, and execute the following command:
.\fastboot set_active a

Thank you for you reply. I did see the instructions and tried the script while connected in fastboot mode. I tried the miui tool and relocked my device while and now I am in fastboot with locked bootloader. I was reading about EDL mode help however the first attempt came back unable to enter EDL because bootloader locked. I decided to step away for a few days to take a beat before going further.

First of all I would thank Crowds he is the best reference that I've to return in case of any problem I face. (He doesn't sleep - any time I ask he immediately supports)
I bought Lenovo K910 and I've managed successfully to install new ROM "VIBEUI_v2.0_1443" and Gapps with Crowds support.
I advised two of my friends to buy this good and cheap phone. For one of them I installed the latest rom successfully. But with the other I had a big problem The phone stuck on Lenovo Logo.
I was trying to install TWRP 2.7.0.0 batch before installing my new ROM, but during installation and after the phone rebooting the batch command screen shows <Waiting for Device> and the phone is stuck on logo screen.
I tried to connect the phone to PC many times, but PC doesn't recognize the phone. When I try to turn off the phone by pressing the power buttons, the phone restart on logo screen like the shown in this video.
I've read in many site that I have to do the following:
Download and install "minimal adb and fastboot"
Just type on the command line without pressing Enter:
Code:
[COLOR="Blue"][B][I]fastboot [COLOR="Plum"][STRIKE]boot[/STRIKE][/COLOR] recovery.img[/I][/B][/COLOR]
you should place your recovery image file in "minimal adb and fastboot" directory
The phone should be disconnected from computer and completely off (press the Power button for 10 seconds - in my case the phone is restarting)
Press and hold both volume buttons, then connect the cable to the PC.
Once the phone vibrate, press Enter to execute the recovery command line
Click to expand...
Click to collapse
In my case when I press and hold power button the phone is restarting on logo screen so I have to wait for battery consumption
I tried many times with TWRP images but it failed...
I tried with CWM image and it succeeded to load, but I don't have otg cable to load recovery or ROM from usb storage (The problem was in installing TWRP and my ROM should has no problem)
I want to flash TWRP on phone not only loading by "minimal adb and fastboot".
I decided to flash TWRP 2.7.1.2 batch through modifying the batch file. I just used fastboot commands
Code:
[COLOR="blue"][I]fastboot oem device-info
fastboot oem unlock
fastboot oem device-info
fastboot [COLOR="Red"][U][B]flash[/B][/U][/COLOR] recovery data/recovery.img
fastboot flash aboot data/lock/emmc_appsboot.mbn
fastboot flash rpm data/lock/rpm.mbn
fastboot flash sbl1 data/lock/sbl1.mbn
fastboot flash dbi data/lock/sdi.mbn
fastboot flash tz data/lock/tz.mbn
fastboot reboot[/I][/COLOR]
Finally I succeeded to install Recovery and phone works well in the new recovery mode and the system mode that I've not update it yet
I want to share you the problem solution in brief:
Download and extract this file "flashrec TWRP v2.7.1.2" from here
Just select without executing "flashrec_Modified.bat" file from the extracted files.
The phone should be disconnected from computer and completely off (press the Power button for 10 seconds or wait for the battery to be almost empty)
Press and hold both volume buttons, then connect the cable to the PC.
Once the phone vibrate, press Enter to execute the recovery batch file
and as me the phone start the recovery mode in TWRP and can be rebooted in system without any problem
i must extract "flashrec TWRP v2.7.1.2 this file on phone or where? can u explain a

As long as the hardware is not physically broken, your K910 is unbrickable

You need to carefully follow each steps in the method - if you short that magic pin and then connect the USB cable (with battery disconnected), your computer will report seeing the device at either COM port 9008 or 9006. Then you can download the factory image to revive the phone. Of course you need to have the right device driver installed. Like I said, as long as the hardware is not broken, this procedure will succeed for sure.
I love you man!
I love you man! I wish you all the happiness and wealth!:victory::victory::victory::angel::angel::highfive::highfive:
I'm sorry that probably many have asked the same quesiton, but I'm desperate. The case is I followed the guide on rootyourmobile dot com how-to-unlock-bootloader-install-twrp-and-root-huawei-honor-7 to unlock, install twrp and root. All went good until installing SuperSu through TWRP, where the installation process got cancelled and I'm now stuck at honor-logo. I can still access twrp(it's in chinese though), by holding volum up + power, but I dont manage to access fastboot mode.
I realize this is a way to go. I guess my problem is not getting into fastboot, I also tried all options under Reboot in TWRP. Should I let the battery run out? Any help is much appreciated. Hope my phone is not total garbage...
DigiGoon said:
Okay follow these step, if you don't understand any step ask again. But follow these:
Download the UPDATE.APP of the Build number you were on before.
Extract system.img, boot.img, recovery.img, cust.img from that UPDATE.APP
Flash all these files via bootloader mode, to boot into bootloader mode, once a loop is over and you see blank screen on your phone, quickly press Vol DOWN button and while pressing it connect your phone to a PC. If this doesn't work and you get into recovery, then in recovery go to option Reboot, in that select Bootloader.
Once in bootloader mode, flash these files by firing these commands from a CMD, make sure files are situated in the same location where you open up the CMD.
Code:
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash cust cust.img
fastboot flash boot boot.img
Now after your phone boots up normally, put the same UPDATE.APP from which these files were extracted in dload folder of your external SDcard.
Now switch off your phone and press all the three buttons(Vol UP + Vol DOWN + Power) simultaneously.
Flashing process will start.
Hope this helps.

No need to open a separate threat. Check your post.
Why are you quoting my post and starting a new thread with it?
So, i installed Xposed, and like many people, i got stuck in the logo... No big deal there... Went to look for some help, and it said to go to fastboot, so I went, but it got stuck in the fastboot logo. Then I connected it to the computer and when I try to list the ADB devices I Ialways get an error saying the server is outdated...
I really need some help! I can't find anything online to help me!
Thanks in advance!
Edit: I submitted a bootloader unlock request to Xiaomi earlier today, but I can't see if its approved or not because phone doesn't work
well,
if you are in fastboot mode then the command is "Fastboot Devices", Not "adb Devices"

and about boot loop problem try to flash miui fastboot rom.

And about bootloader request problem you can go to edl mode and flash miui without any permissions

I tried, but i cant seem to go to edl mode through fastboot, any tips? and because of bootloader lock i cant flash fastboot rom with MI Flash
Edl mode needs a specific fastboot version.
For the Redmi Note 3 Pro / Special Edition
Download and extract this package on your PC.
Enter fastboot mode by holding Power and Vol- at the same time. Wait until the Mi Bunny appears, then connect the phone to the PC.
Run reboot.bat in the extracted package. A command prompt will appear. Press a key to reboot the phone to EDL mode.
Upon entering EDL mode, the screen should turn blank. The notification LED might be blinking red. Done.
To get out of EDL mode, hold the Power button for about 10 seconds.

Above quote taken from xiaomi reddit wiki.
If the above doesn't work, see the link for deep flash cable, shouldn't be need for kenzo/kate.
How you flashed/installed xposed on locked bootloader is another question?
You may need to update your adb/fastboot version + device drivers(adb)

Installing Mi Flash should have put the correct drivers on your PC.
But can be got from here: - https://xiaomifirmware.com/downloads/download-pc-drivers-xiaomi-redmi-note-3/
And I already linked adb/fastboot tools.
IF your comfortable opening your device, there is also a test point method you could try.
http://en.miui.com/thread-244814-1-1.html
Could not find a English video, so maybe try googling more and you might find one.
If not, you could ask at local repair shop, if they would fix it for you. Using Cable/ TP method.
Note for other readers:- MIUI roms need a special version of xposed, for it to work. And installing from an app would more than likely would have use the wrong version. Should never be done on a locked bootloader, only asking for trouble. (Rovo89 is currently trying to bring MIUI support to the official version for nougat roms)
hello all
i spent last few hours looking for solution to how to flash Stock Rom to my YB1-X90F and i found steps here and there and finally i got it. so i gathered all the steps in one thread to help whoever want to flush back to stock or downgrade from newer version for any reason.

1. do it on your own risk, I'm not responsible for any damage to your devise.
2. Unlco your bootloader here is the steps by earthCallingAngela ----->>> Here
3. if you having issue to connect your drive to your computer while on bootloader you can install Intel driver, its worked for me, ----> Here
4. now install Intel Phone Flash Tool, i think it will install drivers as well, download it from here
5. Download Yoga book YB1-X90F Stock Rom Uploaded by Flippy498 from here
6. open Intel Phone Flash Tool and boot your phone on bootloader by Vol Up + Power, you should see the tool detect your Tablet.
7. on intel tool click on brows and located the Rom, wait for the tool to unzip it,
8. do not change anything just click on Flush and wait for it, on the middle of the process the tablet will ask you if its ok to wipe user data choose yes
after that the tablet will reboot and finish the installations and power off itself, power it on and wait for it, its will take long time for first boot so do not power it off.
Halo keyboard will not work until you do these steps By vimalbhimani on here
a) Open ‘’contacts’’ app, create a new local contact ” test”
b) Click search button at contact
c) Input ####6020# code into search bar
d) a list of country codes will po up, browser the country code list, then chose country code US and click OK
e) Then device will reboot and update, you should be able to use halo Keyboard after that.
note: i have issue with TouchPl keep stopping, had to chose google instead of Lenovo to get it to work without error
if you want to update the system to latest version (7.0.1) you can just go to update and update it.
if you have something to add please do
Thank you all.
Here's an alternative method for those who don't trust flashing tools due to bad experiences and prefer flashing files manually via Fastboot (like me):
Follow steps 1. to 3. and 5. of the opening post.
Unzip the stock rom (archive) into your ADB/Fastboot folder.
Boot the tablet to the bootloader (c.f. step 6. of the opening post).
Use the following commands:
Code:
fastboot flash gpt gpt.bin
fastboot erase misc
fastboot erase persistent
fastboot erase frp
fastboot erase metadata
fastboot format config
fastboot format country
fastboot format cache
fastboot format data
fastboot format factory
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash config config.img
fastboot flash country country.img
fastboot flash system system.img
fastboot flash bootloader bootloader
fastboot flash oemvars bootloader_policy-oemvars.txt
fastboot flashing lock
fastboot continue
Execute each of them with Enter and wait till a command got executed completely before you try to use the next one.
It might happen that you face an error while flashing that oemvars bootloader_policy-oemvars.txt. I couldn't find out why that happened and ignoring it seems to be harmless.

c) Input ####6020# code into search bar
d) a list of country codes will po up, browser the country code list, then chose country code US and click OK
e) Then device will reboot and update, you should be able to use halo Keyboard after that.
note: i have issue with TouchPl keep stopping, had to chose google instead of Lenovo to get it to work without error
if you want to update the system to latest version (7.0.1) you can just go to update and update it.
if you have something to add please do
Thank you all.

I followed all of the steps and it says "Flash Failed (Fastboot) PLEASE HELP
Edit: I fixed the problem by simply rebooting it. I didn't think it would be that easy.
SameSame, but L-Version ... cannot find Stock ROM ...
Hi there,
I would like to downgrade 2 Tablets YB1-X90L (not F), this thread is onderful BUT I cannot find the STOCK ROM version for the L-Model (the one with LTE) ... can someone point me out as where to get it ? The background is that Nougat screwes up the playstore ... as discussed in many other threads and there is no -permanent- solution... Thank you!

found myself in the same boat and eventually came across this:
https://cloud.kolyandex.su/index.php/s/npeVhVlnJw8BFIy
hopefully it sticks around long enough for others to grab.
note that the steps are slightly different in that you have to manually select the .json in the extracted folder.
Could someone please help me with downgrading my YB1-X90L, it just refuses to boot at all after my nephews messed with it, I found the stock rom but I can't get some of the needed programs and drivers,

Here's an alternative method for those who don't trust flashing tools due to bad experiences and prefer flashing files manually via Fastboot (like me):
Follow steps 1. to 3. and 5. of the opening post.
Unzip the stock rom (archive) into your ADB/Fastboot folder.
Boot the tablet to the bootloader (c.f. step 6. of the opening post).
Use the following commands:
Code:
fastboot flash gpt gpt.bin
fastboot erase misc
fastboot erase persistent
fastboot erase frp
fastboot erase metadata
fastboot format config
fastboot format country
fastboot format cache
fastboot format data
fastboot format factory
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash config config.img
fastboot flash country country.img
fastboot flash system system.img
fastboot flash bootloader bootloader
fastboot flash oemvars bootloader_policy-oemvars.txt
fastboot flashing lock
fastboot continue
Execute each of them with Enter and wait till a command got executed completely before you try to use the next one.
It might happen that you face an error while flashing that oemvars bootloader_policy-oemvars.txt. I couldn't find out why that happened and ignoring it seems to be harmless.
Follow steps a) to e) of the opening post.

It would be great if someone can helb me.

sorry for replying to such an old post.
could you or anyone else please reupload a 6.x stock rom for the yb1 x90L? i just cant find any working link and am currently stuck with a device without properly working wlan. wlan keeps turning itself off after a few seconds after reboot and only restarting the whole device can turn it back on again... i hope a rollback can solve the issue...

looks like the original link is down, so i searched for the file name YB1-X90L_USR_S110085_1710170829_WW08_EP_ROW_otafull.zip and this came up:
YB1-X90L_USR_S110085_1710170829_WW08_EP_ROW_otafull.zip | Easy Firmware
easy-firmware.com
ive no idea if this is working or safe to use but its a start.
good luck
So my Android YB1-X90F was locking up when trying to boot, just stuck showing the Lenovo logo. Thinking I'm clever I stubbled across the boot menu if you start the device with the Volume Up held. From there I tried the Recovery Mode and did a Factory Reset. Then the tablet started up and shows the Green Andriod Bin Man, saysi Encrypting and promptly reboots. So one starts Googling and ends up here. Some very help information, thanks for that.
So I've got as far as installing all the drivers/Intel Phone tool/Android Suite etc. but I'm still stuck. The flash is locked. Is there another way to unlock this as I can't get into Android to allow the developer options as suggested in Step 2 of the opening post?
Trying the fastbook commands in post 2 also fail
Code:
FAILED (remote: Prohibited command in locked state.)
finished. total time: 0.170s
TIA
LOL @ me, of course the manual fastboot commands fail as that's precisely what the Phone Tool App trying when doing its magic.

I'm in the same boat. I acquired a YB1-X90F but all it does is show the orange Lenovo splash screen, then a black screen.
So here I am reading threads. But I'm already at my first hurdle...since I can't boot into the OS and go into Developer Options to start the boot loader unlock process.

Solved. I ran 'flash_update_from_user.json
Just waiting for the battery to charge to 30% to hopefully enable the Halo Keyboard.
Here are the files needed in case other links void in the future: https://drive.google.com/drive/folders/1gD9FyA03GbLZ7ZcjkyMDlhVPs4_em2rY?usp=sharing
Edit: The Android N update bricks the device for some reason.

The link is not work anymore, could you please share you firmware for x90L model ? thanks
I tried to root my phone using this guide, followed it down to the word and yet my phone's stuck in a bootloop. It keeps restarting to the Poco start screen.
Ive got the stock recovery, and for some odd reason fastboot commands work only in the "FASTBOOTD" screen and not the the "FASTBOOT" screen which you get from "adb reboot bootloader" command.
I try to shut it down and it boots up back again in the same screen and is stuck there.
Im clueless and I really dont know what to do. Some help would be greatly appreciated.
edit: I tried to use the stock recovery and wipe data. No progress.
I tried to connect the phone with the MIAssistant but the app doesnt recognise the device.
I tried using the MiFlash tool to flash the stock rom, it goes on infinitely. Im currently trying to use the SP Flash tool and MediaTek Bypass tool but I havnt got any progress yet.
I promise I'm never buying MediaTek devices ever again.
Careful with the Flash and Bypass tools, they can cause problems.
What can you achieve with the hardware buttons on the phone? Can you get it into recovery?
Fastbootd working but fastboot not sounds like a USB drivers problem - there are some driver options here.

It was a driver issue, thanks for the link.
What I did to get out of the bootloop:
1. Download the latest Miui rom for your version, make sure it's the recovery version and not the fastboot one.
2. Press ALL the buttons, Vol+ Vol- and Power button to shut it down for a few seconds (assuming you can't switch it off as it keeps powering back up again).
3. After it's switched off, quickly press the power and vol- button until you see the FASTBOOT screen.
4. Connect with PC, make sure you have the proper drivers and have connected with the right USB port.
5. Download OrangeFox custom recovery. It is a unofficial custom recovery, so its stability is questionable. But it does the job here.
6. Copy the OrangeFox zip and the Miui rom file to your phone's SD card or any external storage which your phone can access.
7. In your PC, extract the OrangeFox zip folder in your platform-tools folder. (The folder where you run your cmd fastboot/adb commands)
8. Open up cmd, and enter the command:
fastboot flash boot recovery.img
9. Your phone should boot up to the OrangeFox recovery. If not switch the phone off (Step 2) and press power + vol+ button for booting up to the recovery.
10. Locate your OrangeFox zip installer file in the recovery and flash it.
11. Reboot to the recovery again.
12. Locate the Miui rom and flash that. Before swiping to flash the rom, there is a check box which says something like "flash OrangeFox once the rom has been flashed". If you want to keep OrangeFox as your recovery then check it, or else leave it unchecked. Flashing roms remove custom recoveries.
13. Your phone must reboot to miui.
NOTE: You can use fastboot commands to flash the rom but I'm not very familiar with fastboot commands (I actually forgot most of them). Hence I use the recovery method.
