Lenovo A816 Qualcomm based ROM bug - General Topics

Hi People!
I hope that somebody can help me out with the problem i have. I flashed an Updated ROM via needrom on my Lenovo A816 but for some reason it turned to be with some kind off error.
The ROM seems to work fine but eats battery like mad. Another thing that happens is, it lags on reboot and does bootloop at least 15 times and then suddenly it boots in.
Can somebody help me out with this problem. I can't install twrp or CWM. I tried adb, but no luck at all. I can get into Lenovo-recovery but fno luck.
I would like to copy ROM from my other Lenovo A816 to this so it can be healthy again. I need instructions please.

[Completed] HardBricked Jiayu 3s

Helllo guys, this is two days I'm looking for how to fix the problem but it's two days that I can not.
There are two days I tried to install firmware on my Jiayu 3s while operating, SP Flash Tool said the root had gone well since that day, impossible to turn on my phone, does not start, but does not load is detected as the "Alcatel DNIS # ** Interface" on my computer, I tried several methods; reinstall the drivers, try to reflash ect .. but nothing happens. I know this method before, I had a Chinese firmware (MOLY.lr9.w1423.md.lwtg.cmcc.mp.v9) , everything had gone well, stages ect ..
But when I tried to flash firmware with Europeans, it was bricked the phone and from that day, I can not do anything.
(Sorry for the bad English but I use Google Translate)
Can you help me solve the problem? I you will be very grateful if someone could help me.
My phone has a non-removable battery.

[Completed] LENOVO A816 (qualcomm based) flash HELP NEEDED!

I need HELP with my Lenovo A816.
My phone is stuck, it turns ON and turns off. It comes as far as Lenovo logo and that's it. When it turns on, just vibrates, comes to logo and shutsdown again, and keeps doing that all the time.
I can't access anymore recovery menu, only Lenovo recovery but it does not help at all.
I accidentaly erased Lenovo launcher.
It doesn't get recognized via USB-PC. I tried flashing tools Qualcomm emmc download tool, qpst etc...
Can someone guide me how to repair the phone (flash custom ROM).
I have my wifes A816 which is working ok (except it also needs flashing ROM because of the chinese junk apps nad gapps not working, but don't want to ruin this phone also). Maybe having another would help rescuing my A816.
Please, anybody HELP.
