Hardware version information can be found as part of your device serial number.
Your serial number is located on the back / rear of the device, across bottom ( page view ) * Above bottom line, is printed Model  " V975M " - S/N will begin with V975M ( first 5 characters of S/N )
Also attached on the outside of the box ( printed sticker )
Note the 9th and 10th alpha / numeric in your serial number
9th is always " V ", followed by 10th is always a number
place v next to number = V1, V2, V3, currently V4
this is your reference model number
Model versions change, when internal hardware is changed or added in the device. EX: changed or added internal hardware chip(s)
EX: consider v3 = (v1/v2) + Blue Tooth - when used with mated ROM version.

Your v975m hardware device model version dictates what Onda ROM should be used.
Ex: For v1 hardware mate to v1 ROM
Exception : v2 hardware ( mostly mainland China distribution ) Mate with v1 ROM
If you decide to attempt non-mated / unmatched hardware and ROM
Please remember there are consequences to all actions. Sometimes a little, Sometimes a lot.

Forum posts
Before posting questions that may have been asked and answered many times before you arrived
Read all that others before you have shared. Learn from and with them ...
Look for repeated issues and work-a-rounds, if many are experiencing ... you may also experience
If you experience something not posted, make a post, focus on the issue / problem, ( not just " it worked last night now my screen is black when i touch the power button, what do I do ? " ) provide enough information so others may help or direct you where to find needed additional help ... Include device version and Firmware version
If unknown issues surface and are not discussed, how could anyone expect a solution ?
Try to keep post in the proper ( existing ) thread / topic. EX: NOT posting 4.3 stuff in a 4.4 Beta thread.
Do not start a new thread because you may not have time or are unwilling or cannot read.
Redundant threads may be closed, removed or locked by Admin. You may not receive any help.

Many folks will not respond until they have a positive result to share ... this often takes time. ... folks may be 1/2 world away .. or down the street.
For most all problems there are existing solutions. Solutions usually begin with patience.
* Note:
Having the same help post in multiple forums / threads / topics, across multiple sites / forums may create additional confusion and anxiety for you and other members. If you do not respond to every individual post reply received ... those folks that may have a solid solution may assume you found a fix that worked. Check your posts daily. After a few days ... others may ignore post and move on
Do not expect folks to know your current position, when they discover conflicting thread chains..
Always post some type of follow up letting others know status or solution .... to all sites posted.
