My phone wont upgrade froM the sd card or the cache in the recover menu it states its depreciated (the cache) and its unavailable (the sd) eveb know they operate properly not in the recovery menu. Also when entering the recovery menu on the bottom in yello text its states "tz data missing: bitmap_stageempty missing (code-7)" new line " yz data missing:bitmap_stagefill missing" im pretty sure thats how it states it but i know for a fact this is what it says. What does tgis mean. Also i cant backup my device from google bit its is connected to my acct.. So many issues so sad i agree with other this is my last zte i had zte for years why are you guys such lags on helping us out on this phone you offer help but common your choices of help suck i have already sent it in cuz it gave me 3erd degree burns on my hand and it came back with software issues now you want me to send again seriously... I juat want a new phone n yhen i send this one back no you want me to wait 2 weeks after i send this on in. Totally unreasonable.. Help a sister out and fix tge dang thing already.
