Hi there. Please help me to root my Xiaomi Qin2 phone with SC9832E CPU. I dont have pac firmware, but i have full firmware in update.zip.

It have OEM unlock option in Dev menu but none of any ways to unlok bootloader i try is works. It doesn't have preinstalled GApps so it's hard to use it in full way. So i need to unlock and root it.

It seems that bootloader isn't unlocked. Ive read thread https://forum.hovatek.com/thread-19578.html and fastboot getvar unlocked command were well runing. But flash patched bootloader shuts whith unlock it first error. So i try next all the other bootloader unlock command and it won't works. To flash pac file via ResearchDeweloperTool I dont' have a pac file only update.zip

This is what i get:

Code:

C:\Xiaomi_Qin>fastboot getvar unlocked
unlocked:
Finished. Total time: 0.002s

C:\Xiaomi_Qin>fastboot oem unlock
                                                   FAILED (remote: 'unknown cmd.')
fastboot: error: Command failed

C:\Xiaomi_Qin>fastboot oem unlock-go
                                                   FAILED (remote: 'unknown cmd.')
fastboot: error: Command failed

C:\Xiaomi_Qin> fastboot flashing unlock
                                                   FAILED (remote: 'Not implemet.')
fastboot: error: Command failed

OEM boot unlocked is turned on in Developer menu

ensure you're using latest adb & fastboot version, you can check the version using the command "adb version"
if the output is version 1.0.41, then you're using the latest and it must mean that your device requires a special command / token or key to unlock bootloader. Unfortunately, only the device OEM can provide that

for PAC file, you'll need to use Cm2 dongle to backup firmware from your device and create a PAC file (this doesn't guarantee root success as some spd device wont allow flashing signed factory files). If you can find someone having cm2 dongle then its worth a trial

That's suxx ((( But can i search for correct unlock command/secuense in u-boot.bin?

it's very unlikely that you'll get the right command from uboot, moreover you do not know if the device uses special command or token / unlock file or worse case scenario the device could require both special command & key but there's no harm done in trying
you could try using the guide @ https://forum.hovatek.com/thread-21403.html ; since you already have uboot file,  simply jump to Step 3: Read the Bootloader file

No at all. its' not true Xiaomi its a division of it as I undastood. It have Duoqin.com service account for SMS/Contact sync, remote locating etc. and I can't register in it coz of chinise only phone number it request. I can share FullOTA if ya interesting to look inside of uboot and bootloader. https://yadi.sk/d/K0EFeekyddtQ7w
there's two firmware available - common one (1.x.x) and so-called study one (5.x.x). Last one is with some study apps preinstalled and blocked sideloading. Common one is with sideloading ability. Both of FW have limit to instsall apk within phone UI to 6 apps. While it doesn't affect in sideloading at common fw. At JD.com Qin 2 Pro version available with 2 GB RAM and 12 app limit and newer CPU.

You'll need a CM2 dongle + module like CM2SP2 before once can even begin exploring on this device..unless you can somehow find a pac file

Ok now we have a PAC fw ready to flash. How can we research for unlock boot and next root it?
