[sBricked] Hisense Sero 8 Pro - No Command [Help!]

My Hisense Sero 8 Pro recently updated, the update failed and now it shows the broken android with 'No Command', I looked online and everything seems to point towards recovery mode, the thing is though the Sero 8 Pro does not have any volume keys they are software side, it does however have a small pinhole which i assume is a reset button but i tried poking/pressing/holding it with and without the power button being held down, trying those routes, i tried looking for alternate ways to get into recovery mode and found using ADB works also, tried that to no avail as the commands seemed not to affect the device, this was made harder as the device was only detectable by ADB for 5 seconds during boot up, I also tried using ADB Hard Reset but found out that my device is rooted which was strange as all my attempts to try to root the device failed, according to root checkers.

So now I'm asking Online for some help, quick recap;
- Hisense Sero 8
- No Volume Key
- Pinhole Reset button?
- 'No Command' Screen
- Failed Software Update
- Rooted (Apparently)

If anyone wants a challenge i think i just proposed one.

[WIP] command line nandroid-like backup all variants

Ok, so I successfully rooted my H810 G4 via LER. I was impressed with being able to dump the system.img of my phone, inject root into it, then write it back to my phone. So, I thought, why can't we just back up ALL the partitions of our phones this way and if something goes wrong, those of us who do NOT have a KDZ or TOT file to flash back to original factory can just go into download mode and dd our phones back to factory!! Now I have followed this tutorial here:
http://forum.xda-developers.com/show....php?t=2450045
to learn how to dump partitions. HOWEVER, what I do NOT yet understand is why he does not use any of the bs,skip,count variables in the dd command. So I need help understanding these and I am doing more reading on it here and there. What I don't know is are these variables partition specific, or are they only PHONE specific and we can just use the same variables for each partition?
I have an ATT H810 running H81010b firmware. Here is all my partition info!

So if you guys can chime in and help get this figured out, also I will post updates for what I learn about it. Hopefully we can get this so that we can do backups this way until we get a custom recovery for the most of us with locked bootloaders!:good:
