  1. Cural explains it very well You can change it without flashing anything by using Trickster MOD after remounting rootfs as r/w.
  2. Welcome, welcome! Here's hoping you enjoy your new tablet!
  3. You and rozak should discuss integrating this fix into his ROM by default. This is causing way too much confusion here. Obviously, with the latest kernel, the fix only works until you hit high temps, but still.
  4. "Lag" is such a general term and can mean so many things. I have no idea what you are specifically talking about. However, as a quantifier of "smoothness," 60fps in the UI is the goal for Android 4.3+. This tablet does not do that, so it feels like a bloated horse carcas to use. It's really easy to measure framrate using an app called FPS Meter. Interestingly, none of the scripts or tweaks that members of this forum claim increase smoothness actually effect frame rate in any way. This means most are either suffering from the placebo effect, or are talking about something else when they say "lag" and should be more specific. It is so easy to check the frame rate - it literally takes like 5 seconds to mess around with it and post a screenshot. But very few do, for whatever reason.
  5. You will not be able to do that. These tablets do not work like traditional PC's.
  6. This forum is starting to feel really unorganized, and many people are asking repeat questions that are already answered in threads but are impossible to find. I know there are people who are on here often and post a lot, but are not devs. Why not make them mods to help shuffle around and tag posts? They are obviously people who want to help out. Otherwise, I think this community is too small and busy to maintain the forum.
  7. I am experiencing the same thing as you SciBee, and had come to the same conclusion. This is the first documented evidence of the problem, though, as well as the solution, so thank you soooooo very much for taking the time to do a write-up on this. We need more people like you working on this tab.
  8. Mods, Based on what I have seen over the past few days, with posts that contain the equivalent depth of "lol just got dis wat do now," this is a thread that is sorely needed. I'm not sure the section this belongs in, but it is probably worth a sticky, wherever it goes. All, I whipped this up today while waiting on some laundry. I will continue to work on it (along with the other threads I started on this forum) throughout the week. Feel free to comment if you notice anything that needs updated changed, or have something you believe is worth adding.
  9. INTRODUCTION Hello, and welcome to the forums! Unless you are lost, you are here because you have just purchased or are looking to purchase an ONDA v975m tablet. This is an unofficial website created by a community of ONDA v975m owners. We all come here in order to share our resources and experiences in order to help each other learn how to use, modify, and develop for this device. Although this remains a small community, it has come to our attention that the sheer amount of information we have compiled has become too large and unorganized for most newcomers to easily navigate and understand. Because of this, we have spent a great deal of time to compile and streamline all of the information you need to start off into this single post, so although it is long, please read it in its entirety. The goals of this post are as follows: To help you determine if the ONDA v975m is the right tablet for you. To give you a basic understanding of the hardware in your device. To provide you an overview of the Android operating system. To describe and link to all the most up-to-date modifications that are available to you. To inform you of all current bugs and issues with this device, as well as known solutions. To point you to places you can go to find further help if you need it. Again, let me stress the importance of reading through this post in its entirety before you do anything else. This will help you to make informed decisions and avoid costly mistakes, and will help us by reducing the number of help requests on the forums. Without further ado, let us begin! IS THE V975M RIGHT FOR YOU? If you have just received your new ONDA v975m, or you are considering purchasing one right now, you must first seriously consider these questions before proceeding any further: Do you want a tablet that works well as soon as you take it out of the box? Do you expect things like the audio and touchscreen drivers to work properly? Do you want predictable battery life? Do you want to give this tablet as a gift? Do you understand the basic workings of a tablet computer (things like GPU, CPU, RAM, touchscreen, accelerometer, etc.)? Do you have the ability to read, understand, and follow basic instructions written in English? Do you have the time and motivation required to spend hours reading, understanding, and following those same instructions? If you answer "no" to any of the above questions, this tablet is not for you, so return it for a refund now (or don't buy it at all) and consider purchasing a similarly priced device with better support. As it stands, this device does not function correctly, and remains little more than an interesting toy/hobby for developers. This may change in the future, but as of now it seems unlikely. Consider this a warning. REGARDING THE HARDWARE CPU/GPU The v975m is based on the AMLogic M802 system-on-a-chip (SoC), which includes 4 ARM CPU cores that run at up to 2.0GHz and a MALI-450 GPU. The tablet (along with most other phones, tablets, laptops, and even desktops) has the ability dynamically change the clock rate of the cores based on what you are doing. If you are simply reading an email, the clock rate may drop as low as 92MHz, but in a demanding game it may scale up to 1.6GHz or 1.8GHz. This is done to reduce power consumption by the CPU and increase battery life - giving you only as much processing power as you need at any given time. The part of the system which controls this is called the "governor." As you can imagine, is very difficult to design the governor so that it both saves power and gives you maximum performance exactly when you need it. There are some interesting nuances regarding the governor in the v975m which we will discuss later. RAM This tablet comes with 2GB of RAM, of which approximately 1.5GB are available to you. Out of that, the system will eat up about 820MB to run the launcher, background services, and store framebuffers (chunks of data that the GPU uses to represent each pixel on your screen), leaving you about 680MB to play with for your applications and games. This sounds bad - and it is. However, if you avoid installing shitty, bloated apps that run tons of services in the background, you will likely not run into any issues. Internal Storage The v975m can be purchased with either 16 or 32GB of internal storage, so aim for the one that best fits your requirements. In either case, unlike the hard drive on your PC, the internal storage will be divided into many small partitions, including but not limited to: bootloader, boot, recovery, system, data, and sdcard partitions. A "ROM" is a file (or files) which developers create so that you can create/overwrite/update one or more of the partitions on your internal storage. To serve as a reference when investigating or "flashing" (installing) ROM's to your device, we will quickly review what information is stored in each partition: Bootloader The bootloader partition of internal storage contains all the information your tablet needs in order to power on and figure out what to do next, kind of like a table of contents in a book. If you screw up the bootloader, the tablet will not know what it is or what to do, and when you power it on it will just sit there with a blank screen (a hard brick). The only way to recover from a problem like this is to directly access the internal storage hardware (NAND flash chips) and rewrite all of the missing data with a special program on your PC. So, be very, very careful when updating your bootloader. Boot The boot partition contains your kernel and other files related to the very low-level functionality of your device. The bootloader loads this partition by default after it initializes your system. The kernel is the very heart of the system, and controls how all of the individual hardware components work together to make your tablet work. If there is a problem with the kernel, or kernel drivers, different hardware components will not work as well as they should, or will be outright broken (more on this later). If you screw up your boot partition or flash the wrong kernel, your device may behave similarly to a hard brick, but will most likely continuously reboot, displaying the boot logo over and over again (a soft brick). This leads us to the next partition, which is... Recovery The recovery partition on your device contains a miniature, fail safe operating system for your tablet. In case of emergency, holding the volume down button on the side of the v975m will cause the bootloader to load this partition instead of the boot partition. The recovery partition allows you to access and modify parts of the system which you would be unable to otherwise while the device was running. Because of this, the recovery partition is primarily used to flash, or install, updates and modifications to your device in a safe way. It also functions as a way for you to fix any screw ups you may have made. By default, the recovery partition OS has minimal functionality outside of flashing files, so developers have made replacement recoveries which can do a lot more, the most popular of which are called Team Win Recovery Project (TWRP) and Clockworkmod Recovery (CWM). System The system partition contains the Android operating system and all of the apps that come bundled with it. This is the part that most of us are familiar with and interact with on a daily basis. This is also the easiest and safest part of the system to modify, as it is completely separate from your very important bootloader, boot, and recovery partitions. Because the Android OS is entirely open source, developers have created a number of specialized versions for many devices. The two most popular variations of Android are called Android Open Source Project (AOSP) and CyanogenMOD (CM). AOSP is based on completely unmodified Android source code, while CM is heavily modified and includes and number of tweaks and additional features over AOSP. The version of Android you should use is entirely based on what you as a user want your device to do. As a general rule of thumb, however, AOSP works with more applications, while CM offers more features out of the box.

  10. Sorry to hear about your problems. Cracktech. Please keep in mind, this is a very small community, with very few people who have the technical knowhow to develop ROM's, etc., and those who do are very busy. Could you please describe the problem in more detail, with perhaps a link to a post on XDA or similar regarding how to fix it? I'm sure if you post it here for the community to see, one of us here will get around to fixing it. Thanks in advance for your help. We need all we can get, and really appreciate it.
  11. If you install Titanium Backup, you can easily view and remove any apps that are installed. I'm similar to you - I nuke everything except the Play Store.
  12. Ah, so it is likely a thermal limiter. Thanks for the informational post, SciBee! I'll have to grab me some tools here in China, left my regular tools back home in the good ol' US of A. And I agree with you about the price thing. I see way too many people complaining about it on here. As a side note, has anyone ever tried submitting bug reports to ONDA? I've seen many threads talking about contacting AMLogic, but none about ONDA.
  13. I will need to attempt this tonight. I mounted the root fs as r/w and forced my max scaling frequency to 1992000000 with Trickster MOD. I got a grand total of 26 seconds at 2.0GHz before the governor detected high temps and forced me down to 1.1GHz max frequency. At least I think it triggers on temperature... Will need to do more testing.
  14. Welcome! I, too, am interested in the 975i. However, poor drivers (like we have to struggle with on the 975m) will cripple any OS. Also, I am hesitant to get another Windows RT device after my experience with the original Surface RT. As it stands, Windows is just way to heavy and unoptimized to run on an ARM-based tablet. Lag all around!
  15. I often pop back to the site and want to quickly see if there have been any new posts. In the green theme, I see most recently created threads on the right, but what would be really useful would be to see the threads that were most recenlty posted to and when that was. If this forum runs on PHPBB, I'm almost 100% there is a plugin available for that.
