You need start flashing process and then connect switched off phone to PC.
Some users mentioned that they press and hold volume rocker (up or down) while connecting in to PC.

That takes mt to recovery or factory mode.
It allways goes to charge mode.
One detail, when connected normaly, if i plug the usb it still only charges, no connection to PC.
Tried multiple cables, pcs usb ports everything. It´s probably hardware, but what part? system board? sub board? battery?
I´m clueless

You no need battery for flashing so if you want you can open phone disconnect battery and flash system.

Too go to recovery mode you need also have pressed power button!!!!! So by my opinion you still doing something wrong or power button in your umi super is faulty and is stuck on. Try press power button and you should hear clicking sound!!!

Connection to PC you can only get if phone is on and unlocked.

When i connect USB it acts as if i have pressed power button and takes me to the combination of power+ vol key(up or down)
Power button works just fine while operating phone on "on mode" power menu, standby/wakeup, and recovery action selection work normaly
It clicks and i can sense it when i press it so i don´t think it´s button´s problem.

Connection to PC you can only get if phone is on and unlocked.

Yess of course, unlocked phone and still only charging, no reply on windows of detected hardware or icon on my computer to browse phone.

I had some faith on this one so i gave it a try, no luck the phone won´t even react withouth battery, i plug in the usb and no response from either side.
BTW, just giving some infos that might be worthy, i have a amp mesure charging deviced, i place it in betewwen charger(original) and cable (original too) and is only charging at 0.7 amps, the battery is around 1 year old, but had a lot of harsh treatment such as playing games while charging, i know its bad for battery´s health, but could that be a problem for flash? Don´t think so, but just in case its a info

I think that you should explain your case from start.
Why do you want flash your phone?
Did you ever flash your phone?
Did you ever connected your phone to PC for downloading/uploading stuff?

Ok, from the start. Tks for the patience by the way.As I told before, i have 2 umi supers one it was mine since it was released, the other was bought a few weeks ago 2nd hand still in the box in a great deal on local ecomerce.
I want to flash it because i want to intall latest ROM on mine and I need SU.
On the second because i want to remove the google protection, from previous owner, after reseting the phone.
I already flashed my phone twice for upgrading purposes, and SU install i think, i never had problems. Allways a clean Job.
I had so many MTK devices, so i´m used to the process.
Connection to pc was allways simple and flawless, but a few months back it stopped to connect to pc (Only charging no phone browsing downloading or uploading) and i thought it was software issues so i dint gave it much attention, in my mind, one of these days I would flash it with latest release and all would be ok.
My surprise started when i would not get the connection for preload flash, i did a factory restore trough recovery hoping it would fix the issue but no luck, still no connection.
I tested the second umi later and the same. I can´t flash it.
I picked up a old Alcatel POP c7 i have just to make sure, BAM straight connection as it should windows drivers loaded and SPFT flashed it in 3m.
I thought it was too much of a coicidence, but apparently it is not. Something is wrong with both of them.
I red a lot on the subject, and i´m starting to consider to solder testpoints so SPFT can flash, if there is nothing i can do. Is it viable? Can you help me?
Thank you in advance
