1.) Go to http://apt.saurik.com/debs/ and download cydia deb.
2.) With iFunbox put in to your device.
3.) SSH to device and perform
dpkg -i cydia_1.1.28~b10_iphoneos-arm.deb
It will fail and will provide the list of missing packages.
in my case it was
cydia depends on apt7-lib; however: Package apt7-lib is not installed. cydia depends on apt7-key; however: Package apt7-key is not installed. cydia depends on cydia-lproj (>= 1.1.10); however: Package cydia-lproj is not installed. cydia depends on darwintools; however: Package darwintools is not installed. cydia depends on sed; however: Package sed is not installed. cydia depends on shell-cmds; however: Package shell-cmds is not installed. cydia depends on system-cmds; however: Package system-cmds is not installed. cydia depends on uikittools (>= 1.1.4); however: Package uikittools is not installed.
4.) debs/ and download missing debs.
5.) Put all deb files to your device.
6) SSH to device and force install missing debs.
in my case: dpkg --force-all -i apt7-lib_0.7.25.3-14_iphoneos-arm.deb apt7-key_0.7.25.3-3_iphoneos-arm.deb cydia-lproj_1.1.12_iphoneos-arm.deb darwintools_1-5_iphoneos-arm.deb sed_4.1.5-8_iphoneos-arm.deb shell-cmds_118-7_iphoneos-arm.deb system-cmds_433.8-14_iphoneos-arm.deb uikittools_1.1.9_iphoneos-arm.deb
7) Install cydia
dpkg -i cydia_1.1.28~b10_iphoneos-arm.deb
Profit.
