Onda v975m ROM / ROOT simple upgrade guide

Onda Official ROM - Onda install instructions

     * Custom ROM installation = follow instruction provided by Developer


Battery 60% +
NO external ( cable ) connection when attempting ROM upgrade / root

** Battery 80+ % - v3 device ( if using OTG method ) see below

Download ( current / selected ) Onda Original file
Un-compress file ( creates a folder that will contain needed files )
Copy included files ( 5 files, generally ) to FAT32 formatted micro SD card

All files ( NOT .txt file ) placed directly on micro SD card ( DO NOT place in a folder on mSD card )
Ex: 1.09v1 ( 5 files )
u-bin.bin ( do not un-compress zip file )

** Note some ROM update versions contain 4 files, ex: 1.05v1

MicroSD card need to be FAT 32 format. ( standard for new package card )
I use a different ( 4 GB or 8 GB or 16 GB maximum size cards ) for Upgrading or Rooting.
If re-using card, safer to format or delete old files prior to attempting upgrade / root process.

Files can be copied using computer / device ( file manager ) to card
You will need an internal card slot or external card device attached to computer.
Card size adapters can be used if necessary, without problems

Files can be copied to mSD ( Ext. ) card via connecting computer / v975m with supplied USB cable
Select - share / transfer file connection type in the v975m ( bottom choice of 3 ) pop up.

When copying on mSD card or USB stick using M.S. computer = safely remove media the Windows way
Always use MS Safe To Remove / v975m “ Unmount “ features to protect mSD card data / USB device and data also future successful accessibility.

With v975m power OFF
Place card into v975m
Hold Volume+ (up) rocker switch - located on tablet side - for 4-6 seconds
Continue holding volume+ while you press and hold the Power button
HOLD both … until you see the ( little ) green Android
Release the power button first,
Release the volume+ approx. 5 seconds later ( usually the little Android will single " flash / flicker " )

momentary black screen ...
The little Android will change position, size, color – ( earlier ROM = big white Android )
note digital completion gauge under big Android

....... relax .... do not panic ............... honest ....... it will happen ...... ready ...... set ......
System will re-boot upon completion ( 10 minutes total , or less )
Initial ROM boot takes several minutes

The device will boot with all Chinese characters

Enter Settings – down left side, tap on “A” ( capital letter A ) Language settings
Language settings - Right Side – Select first ( 1st ) item – scroll down list – select your language

Similar instruction to ROOT v975m
Download root file, un-compress, place files on mSD card
Boot from mSD card following same button holds
V975m will restart when completed.


Edit: Completion time estimates

Estimate 10 minutes ( less ) for brush   

Estimate. less than 1 minute for Root alone 



* NOTE continued root requires DISABLE Google play store auto-update feature, notifications is o.k.
Onda official Root ( SU ) version does not perform root function if S.U. update is installed.


** 22 Apr 2014  v3 device 1.0.9v3 / 1.1.0v3 ROM and newer 

RECOMMEND 80+ % battery when attempting mUSB / OTG connection following OTG update process.

I have a problem. It looks like my 975m dont want to flash even the officalrom. I formatted the card to FAT32 with 4096 allocation value, copied only the 5 files into the root, the card removed safetaly. Tab turned off, card in, hold v+ than power, wainting, the onda logo appers and then comes the recovery menu. The recovery menu dont see the files or the folders on the card (seems formatted). And i tried the burning tool version tool, but in this case i dont get little android (I get the recovery menu instead of the droid ) too. Please help me.


Thank you.
