Problem with G sensor after upgrade

Recommended Posts

Hi, I installed "ONDA_V975m_V3_v2.0.1_rozak_20140515-TWRP V3_v2.0.1_rozak_20140515" on my Onda v975m V3, to install the new version of android "KitKat".

Then I installed latest rozaks Custom ROM for V3.

I think it's really a good job (I hate chinese apps), but I have a trouble. The screen doesn't rotate just from the first intallation.

What should I do? Can you help me?

That´s normal. It´s a bug in the ROM. No help possible. Please install the TWRP-ROM-Backup from RAZIO. Then the sensor works.

Hi, I had the same problem and the only solution that I found is restore the tablet with a recovery of the original firmware, that you can find here:

To do that you need an sd card formatted for TWRP. You can find TWRP here: http://www.ondaforum.com/files/category/3-custom-v975m-rom/

Those files are for the V4 version, so ensure before begin this work.

After that you should have your tablet as new, with chinese language and applications installed.

You need only to set up the language in the options menu (that is in chinese too) and uninstall chinese apps with an app such as "Titanium Backup".

You need root rights of course.

      I'm having a problem with wifi connection, doesn't want to see or recognize my router, I tried a lot of things to do but unsuccessful, I neeeeeed a huge help, don't know anymore what to do.
       Only thing what I noticed that is working is when I attach router on cable, then is working, but again working so slow. I saw some videos that sometimes to fix a problem with wifi on tablets is to move antenna from battery section and it should help for reception of signal, but I don't see how to open my tablet to succeed something like that.

      I recently resolved to finally upgrade to Windows 10, seeing as most of the earlier issues with drivers seemed to be resolved.
      I looked up the subject here, but the information is too disjointed and old. I want to upgrade my x86 Windows 8.1 section only, I downloaded an ISO and formatted a flash drive with Rufus in both Fat32 and NTFS, entered boot options by pressing esc on the keyboard, but the drive doesn't show up in my boot options.
      My only other option is the Media Creation Tool. I have two problems with this option: I don't know what size the download will be and I don't know if I can save the ISO as a backup. I've cleared up the required space (6Gb) on my drive, I plan to overwrite the factory partition with the successfully installed Windows but only after a successful upgrade.
      I need to know which option is best suited for my v820w V3 that is the most up to date.
      I see there's a newer model out, is it possible to use the dualboot ROM of this one instead?

      after the anniversary update 1706 the on off switch is not working any more. 
      I can only send the tablet to sleep by START->Power->etc.
      Waking it up is a gamble, I have no clue why and when it wakes up, sometimes after pressing the volume and on/off buttoms it wakes up minutes thereafter.
      Any idea?
