3utools Unable To Load Restore Ramdisk
Start the DFU mode restore.!IMPORTANT! Unplug the USB right after the screen turns white. This happens after iTunes message 'preparing iPhone for restore' which loads iBSS. Use the payload here to patch iBSS. Now just load ramdisk and kernelcache as usual, then recover your data/fix the system over SSH. If UniFi Video is unable to store inbound video segments to the temporary cache, recordings will not be processed. Verify that the RAMDisk has been correctly configured, is mounted with sufficient space (minimum 3GB), and that the path has been properly set in system.properties. As a result, users can not restore their iDevices using iTunes or earlier versions of 3uTools. 3uTools for 64bit, 3uTools is one of the best tools for iOS users. Launch 3uTools and Click Flash & JB - Firmwares to download the iOS firmware to your iDevice. If i select the ABR10 then the splashscreen is coming and than the Notice unable to load initial ramdisk. Press to proceed. After pressing Enter the system told me: unable to load linux kernel.press After that i am back at the selection tab. In the settings for the Rescuemediabuilder i set. Linux based with windows kind of Harddrive.

The key assigned to load and access BIOS varies from manufacturer to manufacturer but usually its F1, F2 or F12. Once you enter the BIOS, select the ‘Restore Defaults’ option listed in the menu.
Process
iTunes side
iTunes has pretty much no say in how the restore goes along. It will send the DeviceTree, RAMDisk, and Kernel (respectively, as far as I know), but in firmwares 1.1.1 and up the program on the RAMDisk pretty much runs the show. On the Restore RAMDisk, it is called 'restored_external'. On the Update RAMDisk, it is called 'restored_update'.

iPhone side (Procedure)
- Wait For Storage Device (wait_for_storage_device)
- Create Filesystem Partitions (create_filesystem_partitions)
- ASR Stuff (restore_images)
- Mount Filesystems (mount_filesystems)
- Fix Up /Var (fixup_var)
- Unmount Filesystems (unmount_filesystems)
- Clear Persistent Boot Args (clear_persistent_boot_args)
- NOR Update Prep(update_NOR)
Actual NOR Update Routine(Img3_update_NOR)
During this procedure, the system will start flashing the NOR. Interestingly, on devices that don't actually have a NOR (since the iPod touch (3rd generation)), this process still runs and flashes to a special firmware section of the NAND.
- Flash Individual NOR Image(Img3_flash_NOR_image)
- Update Baseband (update_baseband)
