Some of these issues develop slowly until they become so unbearable and disgusting at the same time. You only need to notice the abnormal performance once you start using the gadget.

How to detect the problemĭetecting the problem of some of these Chinese tablets is not far-fetched. As I stated earlier, this is a common problem with Chinese tablets, and I am ready to work you through a step-by-step procedure on how you can fix such a tablet for yourself, friends and family. However, in this how-to guide, I will be showing you how to fix a tablet that won’t turn on or charge. The most common problem with Chinese tablets is that most of them won’t charge or turn on or even boot. There are different types of possible faults, but I have seen many tablets with the same problem. Though these products are affordable and easily accessible unfortunately, some of the tablets are of low quality with very high chances of becoming faulty.

Which kernel sources do you currently use for testing your new H3 based OlinuXinos?īTW: While it’s a good idea to patch this flaw ASAP I would believe that most affected OS images relying on this kernel (for Orange and Banana Pi) are that insecure by design (sudo without authentication for default user) that it doesn’t matter that much whether the fix is applied or not.Īny news on your H3 boards while we’re already at it? 🙂 Until mainline kernel support for H3/A83T isn’t ready there simply has been no alternative if you wanted to run a H3 device a few weeks/months ago.

H3/A83T contain different IP Blocks for many things and linux-sunxi community is still busy writing mainline code for this stuff from scratch. Which ‘better alternative’ are you referring to? The problem only affects Allwinner’s BSP 3.4.x kernel released for H3/A83T last year (not A20 or any other Allwinner device - unfortunately you chose a rather misleading title for this blog post). What does this means? All devices which run Allwinner Linux Kernel 3.4 are subject to this backdoor security flaw and you can easily gain root access on any on them! Here is what OLinuXino Kernel responds on the same command:

(well if you want hardware acceleration GPU drivers are still with binary blobs and no one knows what is inside, but this looks like heap of works and no one is interested to liberate them so far). This is just yet another example what you are exposed to when use kernels which are with binary blobs inside, not speaking of the security quality of the code which Allwinner developers produce!įortunately we use Linux-Sunxi community kernel which is 100% open source and no binary blobs! If the guys from Allwinner were smart enough they would at least hide this in the binary blobs, so no one could see it! embedded always in the kernel you can’t remove it! Some guy decided to try it on his Orange Pi – you see the result, he got root access to the device by simple echo command!ĭamn! and this is put with non-conditional flags i.e. …and while thinking on it, scrolling down I found this: My first though was who the hell will use the original extracted from Android Linux Kernel 3.4 made by Allwinner which contains binary blobs, when there is completely Free Open Source alternative developed by Linux-Sunxi community? What does this means? If string “rootmydevice” pass through sunxi_debug process it assigns you root privileges. I got this interesting Tweet this morning from Ken Tindell decided to check what is this about and expand the message … then LMAO!ĭavid Manouchehri found interesting code in the Allwinner GitHub
