Hi there! Is anyone here that can provide stock rom for Blackview BV5800. I'm from Romania. I bought this phone from iHunt.ro Company. They specify on their website that they are official importers from Blackview and sell this phone under name iHUNT S60 Discovery with a custom ROM, but the phone is very slowly for his configuration. Another problem is the 3G/4G switch. On google play appstore i found this app called "4G only" that allows me to force the phone to stay in 4G network only even there is no signal. Works perfect with other phones, but with this phone, i have no chance. I switch the band to LTE ONLY, 4G network apears for 3 seconds, after that it switch automatically to 3G. That's why i need a stock ROM.

I searched for stock ROM on google. Just one result with a fake ROM i guess, because i flashed on the phone via SPFLASHTOOL with download only, everything works fine until the OK message appears. That was the end of phone life. Won't turn on, not charging logo, anything. SPFLASHTOOL still recognize the phone but i can't write any data on it. When i try to write/download data with SPFLASHTOOL i get this error: STATUS_DA_HASH_MISMATCH (0xC0070004). 
Now i send the phone to their service, i hope they will repair it. But i know it will come back with that stupid ROM, and i still want to install stock ROM. 

If anyone can help me please leave a link. Thanks in advance and please accept my appologizes for my bad English.

Hi there.
Unfortunately such shop isn't an official Blackview Reseller (it changed the name of the phone and installed a custom rom on it!!!!). I can't help you anyway, i'm sorry.

So there is no way to write stock firmware on this phone? Their ROM is modified but the phone is BV5800 at the base, that's how i get here...

hi
this is for (bv5800Pro_v0.1-20180614_FT.rar)
i have bv5800
will it still work?
thanks

No, it will not work.

Today i received my phone back from waranty. Response from service: PCB change. 
My next question is: Can i root this phone, to put another custom rom, because their custom ROM is ugly, and still having trouble with 4g only mode. Even with *#*#4636#*#* menu setting, when i select LTE Only, it switch back to 3g automatically. This is very frustrating! 
If there is someone with BV5800 stock ROM, not BV5800PRO, please, please, please, make an effort and give us a copy from that ROM.
Or help to root this phone. I forgot to mention that this stupid Custom ROM from iHunt, dont have EnginnerMenu. Is Missing  

You're out of the official support channel, i'm sorry, You'll have to deal with iHunt.
