 **[[https://www.hovatek.com/forum/thread-48912.html|Oukitel based on Unisoc chip: is it possibile to fastboot boot from a custom image?]]**
+I tried to root an **Oukitel G2** smartphone, which is based on the Unisoc T606 chip. I tried the procedure based on the script **signidentifier_unlockbootloader.sh**, which uses the identifier token provided by fastboot and an Oukitel leaked RSA key:
+<code>
+./signidentifier_unlockbootloader.sh 473230303030303030303036353835 rsa4096_vbmeta.pem signature.bin
+</code>
+Unfortunately flashing the **signature.bin** file obtained in that way does not work (I used the required modified **fastboot** binary):
+<code>
+./fastboot flashing unlock_bootloader signature.bin
+downloading 'unlock_message'...
+OKAY [  0.001s]
+unlocking bootloader...
+FAILED (remote: Unlock bootloader fail.)
+</code>
+May be this phone is locked with a different **rsa4096_vbmeta.pem** key.
+Does anyone know if it is possibile to boot using fastboot and a custom kernel image?
+I extracted the **boot-gki.img** file from the ROM image, then I patched it using Magisk 26.4 (patching seems successfully), ten in bootloader mode I executed:
+<code>
+fastboot boot magisk_patched-26400_Y9t93.img
+</code>
+But it seems that the phone starts with the stock kernel image, because Magisk says it is not installed and root is not available.
+  * Yes, I enabled the Developer options => OEM unlocking
+  * Yes, I tried the standard fastboot flashing unlock, fastboot oem unlocking, etc.
