S4 (GT-I9505 [LTE?]) stuck in reboot loop, and recovery "System Update" failed" with no recover menu
My*S4*wanted to install an update: before letting it proceed I thought it would be good to*backup*- however after/during*backup*(Kies 3/Smart*Switch on*Windows*10) something happened, and now it fails to boot fully - just ends up on a constant boot cycle, almost as if the system update was run but corrupted.:
Boot (Cycle)
==========
1. get the*Samsung*splash*screen*with the model number, followed, eventually with*
2. the*Samsung*colourful graphics "fireworks" which stop, and then the*phone*Vibrates/buzzes twice, and then restarts,*
3. GOTO '1' - repeating itself continuously.
Recovery Mode
=============
Manage to get a recovery logo by using Power+VolUp+Home, and releasing power at logo. When I do this the device goes straight into a "installing system update" with Droid wiggling ears, then appears to crash out of that with "no command" and comatose Droid animation and return to the familiar faulty boot/cycling behaviour.
When I was backing up, Kies had reported,*
Current version: PDA:OJ2 / PHONE:OJ2 / csc:0J1 (BTU)
Latest version: PDA
K2 / PHONEK2 / cscK1 (BTU)
Size: 1458 MB
Don't seem to be able to do much else (hard reset or wipe cache). I think I can get into*download*mode - Someone suggested using Odin or Kies to re-flash the device with stock firmware, which sounds about right.
Please help.
