Access to UART on Gemini PDA - Planet Gemini PDA Questions & Answers

Hi all,
Does anyone know if there is access to a UART for a serial console on the Gemini PDA?
TWRP was ported so presumably there must be access somehow? (Or did TWRP just merge in MTK kernel patches and it worked?)
Cheers,

hello, nobody has any idea of tools for the Wave 723 ReMaker and trix do not work either the stune.
What exactly NOT work?
Alternate Tool instead sTune is TkFileExplorer_2.4.exe
But as I remember maybe correct, only some settings need to change in menu... for proper work.
Best Regards
Thank you very much mate Adfree

Hubitat Elevation [C7] rooting guide

Hubitat elevation is a smart home hub (Z-Wave/Zigbee/IP). The primary advantage of the device comparing to numerous commercial products is its ability to work without a cloud connection. Unfortunately, Hubitat folks restricted access to the device, so out of the box your tinkering abilities are virtually non-existent. We're going to fix this in this rooting guide.
Hubitat Elevation hardware is built around Amlogic A113X SoC, and it is very similar to Amlogic s420 and s400 boards. It is based on a standard Android architecture and it runs linaro. The bootloader is U-Boot, but the boot timeout is set to zero, so you cannot get to the U-Boot shell/console.
To root the device using this method you will need:
- 3.3v USB to serial adapter
- Some electronics skills
- Linux/Development skills
(Apologies, this guide is not a step-by-step process for for unskilled users)
Rooting Hubitat Elevation C7:
- Open your Hubitat Elevation (there are 4 screws on the botton under rubber pads). Exactly in the middle of the board, you will see an unmarked test point. This is the recovery/bootloader mode switch. If you connect it to the ground and then plug the device into a USB port, your compluter should detect new USB device (Amlogic bootloader port).
- On the component side of the board, find four test points in a row (marked 2TP1.. 2TP4). This is Amlogic UART. 2TP2 is RX 2TP3 is TX (115200,8,N,1). Use a 3.3v USB to serial adapter to connect. If properly connected, you will be able to see boot log and interact with the console.
- You can use pyamlboot to boot from USB. Boot images can be generated using meta-meson (github.com/superna9999/meta-meson). Elevation C4 uses Amlogic A113X, so you need to build for Amlogic s420 or Amlogic s400 board. You need, at a minimum, to build two USB bootloader files (u-boot.bin.usb.bl2 and u-boot.bin.usb.tpl) for pyamlboot.
- Booting U-boot over USB using pyamlboot will get you into u-boot console. From there you can boot Linux kernel from USB, MMC, or set bootdelay for Hubitat's u-boot so you can interrupt the Hubitat's U-boot and get access to its console.
- To set bootdelay option for Hubitat's u-boot, just read environment located at MMC offset 0x27400000 (or MMC block #0x13A000) into memory, edit bootdelay, and write it back to the MMC. This will get you access hubitat's uboot console.
- boot Linux from boot or recovery partitions with edited command line that gives you shell access.
- Once you get root shell, just create a new user, add it to /etc/sudoers, and remove iptables rule in /etc that blocks inbound SSH port. You will not be able to log in to Hubitat Elevation over SSH.
Enjoy the tinkering freedom!
P.S.: Anyone with a password cracker and a beefy GPU, please recover passwords for root and hub users from MD5 hashes in /etc/shadow
I'm looking to go through this now but I have an older Hubitat version. I'd assume the process will be similar though. Is this something that would work for connect to the UART? https://www.amazon.com/Adapter-Seri...+USB+to+serial+adapter&qid=1608139326&sr=8-15
Does anyone have a dump of the firmware?
I have made some progress using the main post as a jumping off point. If anyone is interested in this board message me. I would love to work on this with someone. I am new to hardware hacking.

Does anybody know how to make use of UART points on the board for kernel debugging?

I have no access to adb while booting. When I get a serial connection it's the primary bootloaders output, when it switches to kernel I get nothing.
I have tried changing kernel's cmdline to use ttyHS0 instead of ttyMSM0 but no luck.
Turns out you don't need a serial output to read a failed kernel log. If your kernel version is above 3.9 there's something called pstore driver which copies kernel output to a temporary location on ram which you can access via locating to /sys/fs/pstore/.

How to Backup/dump firmware and webui from Huawei e8372h-153 to a file and downgrade/restore it on another device of the same type

I am a very happy owner of Huawei e8372h-153 that has firmware version 21.210.03.01.1080 and much less happy owner of similar device that has firmware version 21.333.03.00.00
I am looking to downgrade the 21.333.03.00.00 to 21.210.03.01.1080.
Is there a linux based way to dump firmware (and webui) from device 21.210 to file(s)? This would provide a backup before I start playing with these devices a little bit more...
Dumping the images is one important step in a backup procedure and restoring is as important There is more info available on that, but most solutions require Windows OS and a custom software. Is there a way to do it on linux using standard toolset (or optionally some custom tools, but these would need to have source code available for me to trust them).
I don't want to use images available on the network as I also can't trust them without verification and for that I would have to do lots of binwalking.
My initial goal is to replace/downgrade the firmware on the device 21.333 (and my ultimate goal is to get images that I can binwalk and learn from).
So far I have been able to explore these devices a bit
After connecting to USB device is shown (lsusb) as
12d1:1f01 Huawei Technologies Co., Ltd. E353/E3131 (Mass storage mode)
then two interesting devices appear /dev/sr0 (8MB mounted on /media/${USER}/MobileWiFi) and /dev/mmcblk0p1 (memory card partition mounted as /media/${USER}/1234-6789).
usb_modeswitch with option --huawei-alt-mode switches this device to
12d1:155e Huawei Technologies Co., Ltd. HUAWEI_MOBILE
then /dev/ttyUSB0, /dev/ttyUSB1 oraz /dev/ttyUSB2 appear in /dev (the first one allows for AT commands execution, function of the remaining TTYs is unclear to me, but I would love to find out soon)
usb_modeswitch with --huawei-new-mode option switches from device 12d1:1f01 to
12d1:14db Huawei Technologies Co., Ltd. E353/E3131
then only the memory card related devices appear and from what I understand the device is in hi-link mode (it is accessible from browser as 192.168.8.1)
after connecting with test pin number 2 connected to GND I get
12d1:1443 Huawei Technologies Co., Ltd. USB COM
here the device seems to be in boot mode (?) exposing only one TTY (/dev/ttyUSB0) that I have no clue how to use (as I want to avoid using any unverifiable software and Windows OS). BTW In this mode memory card partition also seems to be available.
My main question is: Where to search/explore from here to get dumps of firmware and webui partitions from the 21.210 device and restore from these (preferably also on 21.333 device -- fingers crossed).
Bonus question(s): Where one can learn more about the functionalities of /dev/ttyUSB1 and /dev/ttyUSB2 (in alt mode) and what is the /dev/sr0 (in storage mode) and how to use /dev/ttyUSB0 (in boot mode?
Any help/suggestions much appreciated
Below I include the output of the ^AAT^VERSION? command for both (21.210 and 21.333) devices

How To Install Lineage OS and Optionally, Build Lineage From Scratch
Hello Friends! Today I wanted to re-write a guide for installing Lineage OS on the 2019 Pro. This guide will be more to the point and have only the needed tools. The SOURCE for the Lineage zip shared in the download section below. [/SPOILER]...
forum.xda-developers.com
FOR LINEAGE
THIS GUIDE USES LINEAGE OS AS IT'S BASE, BC I HAD NO IDEA WHAT I WAS DOING WHEN I FIRST STARTED. I WENT THROUGH A LOT OF UNNECESSARY STEPS.
PLEASE USE ONE OF THE LINKS ABOVE FOR DOWNLOADING AND ROOTING LINEAGE OR ANDROID.​
*Hi Friends!*
Today I want to show you how to root your Nvidia Shield, for development purposes, as well as for repairing a soft-bricked system.
Spoiler: DOWNLOAD SHIELDROOT
https://drive.google.com/file/d/13pnW5eiO70b4JIvmbgqNRMhI5g1YHlzG/view?usp=sharing
Spoiler: THE SETUP
Plug your usb hub into the port next to your hdmi.
Plug a usb-c cable into the other port.
You will need an Nvidia Controller, a USB Hub, Portable Drive.
As well as a mouse and controller or a usb 3.0 keyboard
Spoiler: GETTING TO THE BOOTLOADER
Unplug the power cord from the Shield, then reapply it.
Using your Nvidia Controller or USB 3.0 keyboard, hold A and B until the Bootloader shows.
Select Unlock the bootloader.
Select Factory Data Reset.
Hit Reboot and remove the power cord, then unplug the usb from PC.
Wait a few seconds then add the power cord to the Shield.
Leave the USBC unplugged from your PC.
Hold A and B to post back into the bootloader.

Unplug the USB-C From the PC and Reapply.
(Must do to fix broke fastboot after unlock)
Run ShieldRoot.
This will flash the NVIDIA Developer Rooted images.
This will also flash TWRP for us, to recovery as well as boot.
This purposely bricks the system to run TWRP on boot until we finish
Spoiler: FLASHING THE OS AND OPTIONAL GAPPS
Have Lineage and Gapps saved to a portable drive.
Plug the drive into your usb hub.
Select Install in TWRP and start with Lineage.
Do the same thing for GAPPS If you want to have your playstore. RECOMMENDED.
Unless you know what you're doing...
GAPPS Version is the mini TV build so it runs much smoother.
Spoiler: SIDELOADING THE ROOT
----edit, please Know I believe you don't need to do both steps,
-----i had a problem with the flash on either the apk or the zip
------so i just put them both in.
------ ALSO NOTE THERE ARE A MILLION WAYS TO GAIN ROOT WITHOUT
--------MAGISK, THIS WAS JUST THE EASIEST WAY TO PROVE CONCEPT
Go into Advanced on TWRP.
Select Sideload ADB.
Then run the SideloadRootApp.bat file.
Lastly SideloadRootManger.bat file.
Select Reboot system.
Setup your system how you please.
Spoiler: UNLOCK DEVELOPER OPTIONS

I'm still studying everything android, apk, linux, etc. I thought about cracking big name emulators last night, like "Nox, andy. bluestacks" with custom OS full Root, etc, but then it occurred to me what these programs actually are, and it's so simple.
It's just like building androidx86 in a virtual machine, except the programs I mentioned, figured out how to manipulate the machines within the virtual environment, doing their best to shut sudo down, and Sold Out to Corporations, uploading $hitware, on top of their independent, emulated kernels.
So I thought "Why not install a headless (just terminal, no gui at boot version) linux" and then construct the android emulator from scratch?" Well I started researching more based off that train of thought, which emulators work on linux and I learned about the most Special One. https://anbox.io/#collapse2
The logic Is flawless, beautiful, brilliant, but not unique! Thankfully for me, as I am a female that prefers Windows, in a world ran by men that love Linux <3 no Hate. I understand. It is akin to apple vs android, but I digress. I was initially going to install a virtual machine with ubuntu to test out anbox, which I absolutely am going to do, as well as I plan to do everything in my power to get it to work on the shield, muahahhaa, butttttt.....
For Us Windows Users.... THERE IS AN AMAZING NEW DEVELOPMENT WITH WIN 11. I must investigate further, I'm updating my OS now... and hopefully in a few days I can prove my current theory, and share with you guys something Truly Magical in the World of Android, for both Windows and Linux Users.

*ALSO A KNOWLEDGE BOMB*
anyone else who finds themselves on this Journey... I stepped on my shield and in doing so it bent the usb on for my nvidia controller. It also somehow shorted out the system. Lol. Anywho, In doing so, I tried to replace the usb cable with a crappy one I just had lying around and it did not work. I found a newer usb cable and it triggered the controller, so I theorized that since the ports are USB 3.0 or 3.1, not sure, the bootloader will only post with a usb 3.0+ Device. So in theory, any keyboard or controller usb 3.0 should work by holding a + b down

Hello.
Here is where I am at in "thinking outside the box".
So instead of trying to flash windows or ubuntu directly onto the nvidia's system partition, why not flash it to a portable drive?
So I am researching UEFI, Bootloaders, flashing, and volumes, particularly how they store and load data.
So I understand that windows requires it's hard disk to be formated to GPT.
My USB stick is MBR. I have a partioning software that can change the USB to GPT.
If anyone understands what I am talking about, can you reach out? I know this is possible, I know the answer is out there,

""Nvidia uses its own proprietary disk structure on its devices, which look like a modification of GUID partition table(GPT) with protective MBR. Most disk partitioning softwares are unable to read Shield TV's partitions because its primary header is overwritten with non-standard GPT format.
Here are list of disk paritioning software I tried and couldn't even read the disk at all: fdisk, GParted, KDE Partition manager, diskpart and Disk Management on windows. Of course, you may format the disk and rebuild partitions, but then it won't boot from Shield TV at all.
There are two softwares can read partially:
GNOME Disks - the default partition software for Ubuntu, however, could read the partitions IF you boot L4T from Shield TV. It won't work if you try from another computer. Also, it is still unable to modify partitions.
gdisk (GPT fdisk) - gdisk can read partition 2~33 from backup header. As you can see, 33rd partition is the one that holds most of 500GB storage. (462.5 GiB out of 465.66 GiB)""""

All the apps that originally worked, will still work. However, since this process involves flashing a new operating system, lineage, as opposed to the base, stock, operating system, android, you may have to reinstall your favorite apps like dolby
---There are many ways to flash your favorite apps, perhaps the easiest being a program called "send files to tv" you can install that on your phone and tv, then DL the app you want to send to the tv, like dolby, and within SFTTV, You can easily send the app.
You can also use my tools in the shieldrooot but SFTTV is a lot simpler for beginners
Hello,
I am trying to figure out how to either inject a custom bootloader like Clover onto my Nvidia Shield, or to Modify the existing EFI bootloader itself or with a modification to a Recovery program such as TWRP in order to be able to use a custom bootloader to select "Boot From Usb"
I figure I oughta make a backup, but I do not know how to backup my bootloader either....
I think I understand how to look at the shield's partitions now to find the one with the bootloader, I'm just nervous to proceed...
I have been researching for a week and have learned amazing tidbits of knowledge on the sublayers of the shield, and a lot of its partitions...
I was able to install a custom OS, modified GAPPS, and root on my shield, I am just hung up on this final part....
If anyone who understands this would care to share even a bread crumb where to start, I Would Be Ever So Grateful

Hi @jenneh I know you're in the middle of a different train of thought, but since you are one of the most active members recently, I was hoping I could reach out for your help on two really important issues I'm having. I don't think that anyone has been able to get AI Upscaling to function after rooting, and it's one of my favorite features of the device. If you ever have time and are in the mood to crack this nut, I'd be both incredibly grateful and also willing to send like $30 your way.
On that note, I am also having a hell of a time trying to get the AdGuard CA certificate installed. I have tried every method I could find, but none of them seem to be compatible methods for this device. I will both send you an AdGuard lifetime license, and another $30 for this bounty. Any help at all would be greatly appreciated! (Oh, and if you're interested in attempting these feats, please DM me. I'll reply with the AdGuard license in advance.)
One final important note: My device is running the new 9.0.0 update.
Even the new update 9.0.0 AI Upscaling not working after rooting...NSTV 2019 Pro
I tested but same problem Demo mode work only Enhanced Mode
Here's where I'm at now! I am in the Kernel! Not through ADB But instead On the shield Using Root Explorer to learn all of the shield's directories to find out where the hell the EFI drivers are to inject my new bootloader. I see many options pertaining to the upscaling that I can modify but I haven't got the slightest, what it is yall are trying to do. If someone can explain it better we can totally solve this.
----i'm a little weirdo and i have been dreaming about this,, or rather, dreaming in Operating Systems for Months Now~

To Do List:
Will be reuploading the shieldroot tools with wipe all partitions code, updated lineage, etc, as well as including options for folks on other versions of the nvidia shield, all with ammended code. This will take some time to upload / craft, but I will let y'all know when it's done.
Please note, there is nothing wrong with the current shield tools, I am just making them Better! Peace and love
This set me off track for about an hour, if anyone has any ideas https://forum.xda-developers.com/t/a-strange-fastboot-problem.4380579/
