Original&untouched OTA complete update from original 4.4.2 (KK) into 5.0.2 (LP) multilingual with several european and asian languages.
Download both (the file was splitted into 2 parts because of file size limitation) files: update_K920_S226_150429_ROW.part1.rar (SHA1: e9059f48ecc829f0d09a80b99aaaa817cfa27164) and update_K920_S226_150429_ROW.part2.rar (SHA1: 6411834916aacd2880dc03221c0af8b0f6f7038f) and place them in one folder; then ucompress, using WinRAR – the result will be one file: update_K920_S226_150429_ROW.zip (SHA1: 304b69baeea26658713141c41a91e75991c9eddb).
Rename file update_K920_S226_150429_ROW.zip into update.zip, then place (copy) it in \googleota folder on your Lenovo K920 phone. After restart the installation starts automaticaly. Be patient – it takes about 10 mins. to be finished. No data will be lost or deleted during the update, but making a backup before installation is always reasonable.
That download and use of downloaded update is completely free of any charges, so any donations are non-mandatory and optional; just as a favor.
Both rar files are containing 5% repair data.
Have good fun with your new and original Lollipop
