[Question] Can't connect phone to PC,is not detected with Droid Tools, SpFlash doesn't work etc.

[AErkel]

Hi all

this is my first post so please be nice to me if I do something wrong.
Ok, where to begin with my long list of problems...

1. I have an Evercoss A28b bought in Indonesia but manufactured in China. It has Mediatek 6972 and SW version is ALPS.JB3.MP.V1.40 (that's what I could find in the phone's factory mode)
2. I rooted it 2 months ago and put all my apps and data on it from my old phone with Titanium Backup. I had some minor problems in the beginning but fixed them all and the phone was running smoothly.
3. This morning I froze "Go Launcher Z" because I didn't like it anymore and wanted to try how my phone looks withour it. Since the moment I froze the app nothing happened. I couldn't access the home screen or the app drawer but only my recently used apps when pressing and holding the home button.
4. I wanted to reboot my phone but it kept booting and booting, saying "android is upgrading" all the time. After one hour I took out the battery and now it's dead.
5. I tried to reset it into factory mode and first it seemed to work because it asked me to do all the settings like language, google account etc. As soon as I was finished a window appeared with "unfortunately setup wizard has stopped" and now I can't even see my homescreen or anything. My screen is black apart from the battery, wifi and SIM icons in the top right corner.


Now, what I tried to do:

1. I googled and found a few solutions saying I should flash my rom. I googled and found the sp flash tool and a rom for my phone.
2. SP Flash Tool did not recognize my phone and there was no scatter file in that ZIP file that I had downloaded.
3. I downloaded MTKdroidtools to try to generate a scatter file from my phone and a lot of different drivers but none of them made my phone connect with DroidTools.
4. So I went back to SP Flash Tool and googled for hours in order to find a scatter file and make my phone connect with SP Flash Tool. I managed to find another rom, this one had a scatter file in it and I also managed somehow to connect my phone with SP Flash Tools. It was only recognized after I had selected the scatter file and pressed the download button though.
5. SP Flash Tools brought an error message saying my pmt has changed and I need a new one or something like that. Unfortunately I can't even re-do this to give you the correct error message because I can not connect my phone to the PC any longer. Everytime I do this with battery or without it keeps connecting and disconnecting all the time.
6. I am at my wits ends and don't know what to do any more.

Please help

hi, AErkel. welcome to Chinaphonearena.

First of all, good job on getting this far. You've done the right steps as far as I can tell.
For the PMT error, you may want to try formatting with SP Flash Tool before Downloading the ROM onto the phone.
For the connect-disconnect issue, try doing the trick with the hard buttons. Try pressing down on the volume down button or power+volume down or volume up, etc. It could be any combination of those. I believe others get that to work with all 3 of them. If you have a hard home button, you can mix that in, too.

Don't give up on that, you're on the right track. I hope you get things sorted out!
