Mi Max ADB Problem - Xiaomi Mi Max Questions & Answers

After flashing a custom rom "[ROM] [HELIUM] MIUI 8 Global Rooted **Update 12/27/16**", my adb has stopped working. The message says that ADB is unauthorised and the ADB vendor keys are not set.
I've tried to on and off usb debugging, delete adb keys from c/windows/users but to no avail. Any work around?
I'd like to add that I flashed the rom via adb sideload previously. Thanks

I don't think there is , I searched everywhere
I see you did the unlock, for reference the command is: fastboot oem unlock, an on-screen dialogue will appear asking for user verification.
You can use "MTK Extractor" to extract system.img and other files, you can then modify them, and flash them using "SP Flash".
I recently uploaded a clean stock ROM (LEAGOO_T5_OS2.1_E_20180116) to Mediafire and Needrom.
I've also uploaded a carepack if you are interested in the new ROM, or even for a custom.
UEFI ?
Hi, could some T5c owner please check if the path sys/firmware/efi/ exist? Just want to know if it is using UEFI.
My regards.

Download stock rom from miui.com and flash with miui flash when you get in fastboot mode

I do not give stock ROM installed.

Hi! I am the owner of a Xiaomi Mi Max 3.
I tried to update it to a stable official ROM using Miflash, instead of checking the box flash_all I marked flash and lock. I blocked the bootloader.
The phone does not start, it only goes into the recovery mode and a message appears in red at the end of the recovery menu "this miui version can not be installed on this device"
(This version of MIUI can not be installed on this device)
I can not change the ROM using Miflash.
Can somebody help me?
Thanks greetings.

Hello
Yes there are other programs you can try and use: QUALCOMM / QFIL
I had a similar problem with a Lenovo Tab4 8 Plus (8704x) device and this QFIL program and the right ROM files solved the problem for me on that Lenovo tablet when it was hard bricked i.e only went into fastboot or recovery mode.
You need to find all the right version flashing files for your device before commencing, i.e you cannot downgrade a MIUI rom it has to be the same as what was / is on your device or an upgraded version. Unless your bootloader is unlocked :good:
https://en.miui.com/thread-432217-1-1.html
https://androidmtk.com/download-qualcomm-flash-image-loader-qfil
Also maybe you can try adb fastboot program if QFIL doesnt work
https://forum.xda-developers.com/poco-f1/how-to/tool-xiaomi-adb-fastboot-tools-t3887359
One last thing I remember is make sure your Xiaomi device is recognised by the computer in all modes if possible; fastboot, recovery for the ADB drivers or QFIL drivers to work properly. A pop up ballon bottom right PC screen will show if drivers are recognised and ready.
All the best with it
Xiaomi Mi Max 3 Fixed! Entering EDL mode and following these steps.

Need to flash Mi Max

Due to my mistakes with TWRP, now I cannot flash Mi Max, 2016 model. Stuck at Xiao Mi logo and three running dots of Android. Prior to this accident, I used Mi Flash successfully several times. But, safe mode, TWRP still function. Although, charging the phone is difficult and unreliable.
Could you tell me: is it possible to flash the phone without damage to its data? If not, how to extract data from the malfunctioning phone?
I don't remember the complete commands and tutorial but there was a way in which you have to temporarily install TWRP by ADB commands using a PC/Laptop. And then, using the MTP menu of TWRP, you can extract your data.
You can search for how to install TWRP with losing data using ADB commands on google or on XDA
