you will need to go back to the China rom. you can use the rsa tool but replace the global rom with the China rom in the folder windows. it's not a standard rom it's a special type that works with rsa allthough they can be found on github and XDA. so you remember what version you where on

Thanking you for your contribution in creating that EFI for the HP 400 G4 SFF, you have overlooked several things in any case. The mapping of the USB ports is poorly done, in the kext that you created there are several ports that appear as Internal, (in fact there are) but not that many. The Internal USB port on the motherboard where a Fenvi HB-1200 card is connected is not mapped, I was not able to map that port either (it should appear as Internal 255) I don't know if the internal SD RDR port should be activated from the same BIOS ( something I didn't find) and in my case it is necessary to activate it to power the Fenvi's Bluetooth. Do you know how to activate that port that goes inside the motherboard?

There's also quite a fatal bug in 16.0.324 relating to DPI. If you increase the DPI (screen size) by +1 and restart, the tablet gets stuck in a bootloop (the shell/lock screen never loads, and the tablet then restarts after a period of time) and requires a factory reset (resulting in a loss of all data) to recover. Additionally, if the DPI is +1 and you access the extended control centre options (the '>' in the brightness toggle for instance) it crashes the shell and puts you into the bootloop. Basically, avoid increasing the DPI. The CN ZUI 16 (16.0.336) ROM does not have the bug. CN ZUI 16 is also massively improved in regards to its language support.

The ribbon that goes along the stretching part is damaged. I had and iPega telescopic controller which behaved similarly; the right side would disconnect whenever I stretched it. I had to find the sweetspot to keep it working properly but eventually it broke completely. Now I have a BSP D8 Pro, I'm loving it although I know it will eventually suffer the same fate. It's and easy fix, the hard part is getting the right ribbon.

You can change the ribbon, happened the same in mine , i had to ordered it from ali, its a 10Pin 0.5 mm pitch, 400 mm lenght. If you find a 350mm lenght its better but the 300 mm its too short, and thats why it disconnects, use capton tape and rout the ribbon in a way the mecanism avoid crushing the ribbon. Also the D8 pro is better, better quality and improved ergonomics. You can also conect both the D8 and D8pro with a usb c to usb c cable to the tablet and you have 0 latency and conects always as a an xbox. Good videos. I have my Y700 in chinese 16.0.336 version. I hope you can make a video tutorial for those who are already in a higher version. I dont mind the chinese UI but its difficult to follow a guide without any experience.

Global 100 percent but I would double check the china version before you update. I've made a few videos about it. But I would never go back and now it even updates from the lenovo servers only if you use the Rsa method without unlocking the bootloader or rooting which is possible using the method setout in the other videos
@core-computinglab
@core-computinglab Месяц назад
One of the few ways is to fully unlock the bootloader, and flash it through fast boot like you would flash a GSI ROM. But it will break the update stream, so it means you will have to update through a zip file and flash it. From what I have found out about it. Check XDA post, I found they have a lot of great information about the process.
@MyAmazingUsername
@MyAmazingUsername Месяц назад
Your CN version is too high. The CN 761 update (and higher) added a region lock which is saved in a hidden system partition and cannot be removed. If you try the ROW (global) ROM the device will fail to boot. The best you can do is get the NEC ROM which is the Japanese rebrand of the device, if you want to get rid of the Chinese stuff.
