Kind regards

Thanks anyway. I'll be sure to paste a link if I ever find something.

Yes, the same logic applied to the 3328 dont work on 3399...

I tried to build one for superceleron a few weeks back, but had no luck. Difficult to do without the actual hardware for testing.

This thread is an awesome idea. Any chance a TWRP recovery exists for the Yundoo Y8 (RK3399)? I have been looking all day with no luck. Thanks in advance.

ok I did it but it didn't install the recovery, even though it said it was successful. what should I try now? thanks again for your help

Edit: I figured it out through the Rockchip Android Tool. Thanks again for this!

forgive me but its been a while since I've had these boxes, do I do that from the recovery or from within Android?

Edit: nevermind, I think I remember. I have to rename it to update.zip and then reboot right?

Yes, I've seen that bug on several of my RK3328 devices and it's really annoying. The solution is to use the update application from the system partition and select the local .zip file just like you would an OTA system update.

Thanks Magendanz but my A5X has an issue in stock recovery where is can't mount the sdcard because unknown volume for path [/sdcard]. any suggestions? can I just update the recovery using Rockchip Android Tool?

The easiest way is to just install this signed update. You can use the stock OEM recovery or the built-in Update app. https://1drv.ms/u/s!AoqocX31ecnXgZ1Y5wCvIAbEeuhmMA

Hi Magendanz, is there a guide on how to install twrp? I have an A5X Pro with RK3328 and I want to give this a try. thanks!

Just FYI, I updated the build in the link above to remove the damn TWRP App install prompts. I just find them annoying, in a very Microsoft kind of way.

A new TWRP 3.1.1-0 build for Rockchip RK3328 is available for testing here: TWRP3_RK3328-3.1.1-0.img

On Rockchip devices, the offset to the bootloader message block in the /misc partition is 16384, rather than the usual zero or 2048. Unfortunately, support for BOARD_RECOVERY_BLDRMSG_OFFSET is broken pending a pull request that I've submitted.

Also, there are about a dozen or so command-line arguments (wipe_data, wipe_cache, update_package, etc.) defined in Recovery.cpp, but Rockchip felt the need to add a custom one of their own, "wipe_all". I had to make some tweaks to twrp.cpp after the get_args() call to support that. Remember, the Rockchip RK33 bootloader calls recovery directly with this "wipe_all" command-line argument as part of the factory setup after flashing new firmware, so this really needs to be right or you'll end up with a TWRP boot loop.

And for those brave souls who want to make changes or build for other Rockchip devices, I've provided the source on GitHub here:
