[Q] Ployer MOMO2 rk2818 arm9 rooting?

Hi,
quick specs before the tirade:
Brand: Ployer
Model number: MOMO
Firmware version: v2.2.1_00.04-CN *at* 20110625
Kernel version: 2.6.25_(V2.2_3_718DC(E8_R8)_D2_RHJ_A18* at *0728)
Build number: froyo1.00 MASTER.eng.root.20110323.164551
Android version: 2.2.1
CPU: Rockchip 2818, ARM9, 660MHz
Screen: 7.0 inch TFT, Resistive Touch screen, 800*480.
No external hardware buttons for navigation or volume. Only Power button, menu and esc buttons on the top side of the tablet.
* had to replace at symbols because I am obviously sending email addresses or something... *
I'd also love to link the device so people can see what I am referring to if that helps... ployer momo2 should find the ployer.cn web.
--
I am sorry if this does relate to another thread, I am still trying to work out where I am at with this thing, and do not know enough, and I've been searching for days and days putting off posting and hoping it falls into place, but no luck.
I have a Ployer MOMO2 device, which is a cheap Chinese Tabet, no phone, no camera. Here is the URL to the device: .. well i would but cant link.
My problem is I need to get root access to this. I would ultimately like to have a fresh install on it entirely, as everything is in Chinese up until it boots into the os.
There is no Market app on it, and any websites that need flash try to redirect to market: which the device has no idea about. So, I need Market but this is only part of the reason. I cannot uninstall the default Chinese apps, and I cannot use them either.
I also know it has a cramfs filesystem, which is the reason I cannot perm root using z4root. And unfortunately, z4root also fails to temp root the device, failing and then locking up the tablet, or freezing it requiring a cold reboot.
I have tried various version of r4root, having read others have had success. Not so.
I downloaded rageagainstthecage-arm5.bin which is suposed to work with android 2.2.1, and executed it using a terminal app, which proceeded to fork processes and can adb. However, that is where the success ends.
The terminal freezes, as expected, and I force close it. Reopen it to check root, but it won't open. The only way I can access the terminal now is to reboot the device, thus losing any temp root access.
Ugh.
I've tried 1click, as well as other recommended once, but not having the options to boot into recovery/bootloader etc, I cannot complete any instructions on those guides.
I also just wanted to see how I could go about the process of updating the system, using update.img on the sdcard, not intending to do it, but to just gauge the process for now.
It detects the image but says it's corrupt and asks me to delete it.
This was the update.img I got OFF the tablet. It wont even accept it's own? Nah Im doing something fundamentally wrong.
I've been trying so many things, I'm lost.
I simply need to know which direction to attack this issue, and I've seen other rk2818 images out there that have been edited to include root access and market, so for those guys it's possible.
Can someone please offer any advice, keeping in mind I'm not well versed in this, and may require more than cliffs notes...
I really do feel as if I've made complicated something that does not need to be so.
Thanks in advance for any help,
Cheers!

ihave the same tablet u need rktoolupgrade and the firmware from alcordigital website (search on google) .
to install this firmware first open rktoolupgrade ,hold the back key in your tablet and plug usb cable(keep holding back key) windows will find your tablet xp will demand to install drivers(upgrade work only on win xp)choose the driver for xp it is inside rktool folder (driver/86/xp)
open image you will see grren led in rktool then clic upgrade wait when it finish you will see a message (1ok,0fail)
sorry for my bad english i hope it will help you .

[Q] help with IDeaUSA 7" tablet

Hi, everyone
I hope that I am in the right part for posting? I am new to this android thing.
I am trying to find a how to root idea usa 7" tablet from fry's for $77.00. Their is a lot of rooting programs but I have not been able to find anything on this model.
Also what would be a good rom to flash it with? I tried finding out if uberoid and cyanogenmod would work but I could not find any info on this model.
Not to sure what model I have that I would be able to flashing this rom with, either uberoid or CM7? Help
Model: MID, sv7206 v1.4, kernel 2.6.35.7-infotm
processor armv6 rev5,
hardware imapx200,
android 2.3.3,
brand infotmic,
display gri40,
release codename REL
bootloader unknown
I don't know if this is the right model IDea USA IUMID-0071 because the spec's are off. Http ://ideausa.us/produects.html but similar. I am looking for rom that is more update/modern. any potters?
Does anyone have the original rom for this or know how to make a backup this rom?
Well I am thinking that is might be this model but not to sure wm8650,SV7206 v1.4 or IDea USA IUMID-0071.
It's not flytouch
The screen is very slow on this model. Unless you use a pen then is works better.
Also hoping to be able to flash this to ics 4
Thanks

I just bought one, too. What a pos? it works but the screen is almost unusable, lots of mis-fires.
I did figure-out the real OEM web-page,
http://www.sinovideo.com.cn/Products/indexshow.asp?lang=EN&SortID=61&ID=85
This correctly identifies the installed 2.3 OS and reveals that it's some kind of 1 GHz processor. The real performance problem, however, is the 256 MB of memory, ouch!
I have not had any luck finding any updated ROMs. Actually, I suspect the installed ROM is tweaked to work around the defective screen (I think it's configured to ignore any 'touch' lasting less than 0.5 second?) so I'm not going to change it.
---------- Post added at 08:58 AM ---------- Previous post was at 08:49 AM ----------
FYI - I found another site that has lots of discussion about the "M7206" tablet
http://www.techknow.t0xic.nl/forum/index.php?board=51.0

Here's some more info. (Yes, I have continued to investigate even though I bad-mouthed it )
- This tablet is also sold as the "infotmic m7206"
- the screen works MUCH better if you use a stylus
Currently, my tablet seems to be getting about 24 hr standby battery-life, and the battery-usage report says "Cell standby" is using 75%, even though there's no cell radio? Some of the discussion on the techknow forum seems to be about this same issue but all the solutions seem to involve rolling your own ROM, which I'm not prepared to do. For now I just plan on leaving the tablet plugged-in overnight.

Rooting Idea USA Tablet
Oh my, what a mess...
This post is in regards to the Idea USA Tablet (Unable to Root)
My specs:
- Idea USA Tablet (Made in China)
- Model Number: MID (Unknown)
- Android Version: 2.3
- Kernel Version: 2.6.35.7
- Build Number: MID-userdebug 2.3 GRH55 (ENG)
Issues:
Whelp, I have tried the basics and I can't get this thing to root for anything. I was able to get it to hook into the PC through USB. There are 2 usb slots on the side of the tablet. I believe one is for HOST and the other usb is for OTG (Charging). Once I figured out the host port, then I had to download the drivers for this poorly made tablet...But, what drivers? You go to the Idea US website and you get no helpful information. So, there are no drivers made specifically for this $100 dollar generic tablet from FRY's. Ok... No big deal... So, I download the default "Android USB Drivers".
Peachy, it worked! Now, I can transfer files back and forth between the card(s). Wonderful, first step down, next step was to root. So, I read up on how to root with Super One Click.
Ok, so now, I set the tablet to "USB Storage" and "Host"...Then I download and run Super One Click.
Ok, I run the "Super One Click v.2.3.3"; by clicking the root button and then all I get is a frozen screen that reads:
Code:
Killing ADB Server.... Kill Server 0.11s
Starting ADB Server.... StartServer 4.09s * daemon not running. starting it now on port 5037* *daemon started successfully*
And then it just freezes the program. So, now I'm completely stuck. I mean I learned a great deal, that I can hook up a keyboard, mouse, etc to this thing, but, obviously Super One Click was not designed for these generic tablets. I have read other articles which have suggested that the .inf driver for the default "Android USB Drivers" needs to be edited for your specific tablet model and you must enter the specific CODE# for it to recognize for rooting with Super One Click... But, god forbid, I haven't found any useful information on where that might be. Also, someone suggested to install the Android SDK and edit those files along with the .inf files to make this work. But, that didn't work either. I did everything right. I turned off USB debugging and then I would wait for super one click to come up with waiting for device...but that never happened. I even tried it with USB debugging on... still nothing.
Has anyone created a generic batch program to root these types of devices? What am I doing wrong here?

Rooting Idea USA Tablet
Well, this took me all night to read and learn about how to root this basic tablet from Fry's.
First off, I tried many different things and it just didn't work. Using super one click is definitely out of the question for this particular tablet.
I read all night and thankfully found the forum article on how to solve this issue on xdadevelopers own forum.
As per quoted quotes below:
.....You can use gingerbreak to root this. Run it once and let it reboot, then use supermanager free from market to rename the su symlink from /bin/ to "old" or something, and reboot again.
You should now have root ........ It might take a couple of trys but it works.
You need to download supermanager from the market. Enable root in supermanager settings and click yes when superuser pops up.
Then use the file explorer within supermanager to navigate to the /bin/ directory and you will find a sysmlink called su
You need to rename this su symlink to old - completely take out the name su.
Just to be safe run gingerbreak again and then you can install busybox from market.

Thank you so much Pablo11. The idea is to download the APK for GingerBreak from online onto your IDEA USA tablet directly. The trick here is that the brand name is IDEA "USA", but the real workings behind the "MID" is "ViMicro". You will notice that displayed as you turn on your tablet. So, in order to find real information about your MID device, you have to search articles for vimicro.
Once you run gingerbreak, your tablet will go completely nuts. Nothing will run right. Things will break and it will be a complete mess. It will however, install superuser apk. However, it will not work. You can download the Root Checker from the market and you will notice it is NOT rooted. So...thanks to pablo11, you will want to download supermanager from the google play market. Install it.
Next go into the supermanager settings and click on ROOT. Make sure root is enabled and checked marked in the settings. When you enable root in the settings, it will prompt you with "allow root?" Click on Yes. This will give you the access you need.
But, your not done, once again as per Pablo11, go to the super managers file manager section. Get to the root directory by clicking up, and then find the folder "bin". Look for the file "SU" and rename this to "old".
Now, you will be able install busybox and any thing else thats root.
By the way, restart your tablet again, and I "personally" recommend that you go into your settings> Privacy> Check mark both (Backup my data and Automatic Restore) and then click on Factory data reset. Start the tablet from like it was brand new. Don't worry it will keep the root that you did intact. You will just have to re-register the tablet with your existing gmail that you originally used with that tablet.
Lastly, use the root checker from the market and you will see that it is successfully rooted.
Okay... Now, my next step. To crack open this tablet and put in a bigger SD Card as the 2G SDCARD is way too small, especially if you want to use new roms and install a linux operating system onto it....

[Q] Exchange the whole UI stack on Android

Hi
I am new to hacking android. I have built linux distros in the past, and have worked with Linux for 15 years,
I have just rooted a ZTE V965. It doesn't come pre-installed with Play store, and has all sorts of ZTE-specific Chinese apps. It has a good baseband circuit, a good screen, reasonable camera and I think is a great value phone, apart from the awful UI.
It is an android phone, although heavily customised. It has an MTK6589 processor coupled with 4Gb ROM and 512Mb RAM.
I have other phones which operate a much more "Vanilla" android. For example, the Guophone 9105 which also uses an MTK6589. This has a troubling tendency to reboot every random interval. Approx 6 times a week.
I have had success in the past running Linux systems built for much earlier kernels on later kernels. This suggests the ABI (application binary interface) for the Linux kernel changes rather slowly.
I am wondering how well the userland apps are separated from the kernel and drivers on Android.
Specifically, is it feasible to dump all the UI stuff from one phone onto another then change the init to launch the other UI?
Would this risk bricking the phone, or would the shell commands and ADB infrastructure still likely operate?
I guess I should change the bootloader to one that supports fastboot first, right? Is ther a how-to on achieveing this from the root shell?
Thanks for any thoughts
Nick.

Hi Nick, I have the same phone. I'm also very new to android, last phone was iOS and before that windows. I managed to root the V965 using Vroot. I also managed to install SuperSU and CWM. However, the CWM is not fully functional, I can only do a factory reset, not install any packages or roms. Probably the phone has a locked bootloader. I can't check, because the USB driver with the phone doesnt support fastboot.
I really need to get google play working in this phone, read a lot of stuff, tried many things, but I havent succeeded yet. Please let me know if you make any progress.
In China they are flashing this phone, found some ROMs even, but I am not sure how they manage and google translate isn't much help there.
http://www.romjd.com/Device/zte-v965/hot/all/1

Hmmm my V965 is having some issues now
After a factory reset, the setup wizard keeps crashing. Even after another resest. So I can't get in the phone anymore.
Any chance you can send me the USB drivers that are on the phone? My phone isnt deteceted anymore, so I can't access the drivers, which I want to reinstall. And of course they are not on the ZTE website.

Fastboot and ADB appear to be standard protocols, at least on my Ubuntu, which don't need special drivers. However, it does appear that the stock boot loaader on the v965 does fail to incorporate the fastboot option.
If you remove the battery, replace it then turn on holding the volume down, you will get a menu, but fastboot is not there.
I don't know for a fact, but I do suspect that if you have access to the running android system as root, then you could in principle change any of the internal flash data. Therefore, in principle, I guess you could replace the boot loader or anything else in the running android system. Anyone please correct me if I am wrong, or confirm if I am right.
The feature set of this phone seems to be the same as the feature set of my Guophone. MTK6589, dual SIM, etc. So this image may be a good place to start if considering a transplant.
If you have ROMs, then perhaps it is possible to flash the ROM from a root terminal. I'm thinking add the uncompressed ROM to the Micro SD card, then using the dd command, block copy it to the appropriate image area on the internal ROM, reboot, reset to factory defaults.
If anyone more experienced than me with the nuts and bolts of Android can confirm or deny this will work, or where it should be put, please let me know.

An important factor is that the NAND is not locked on the ZTE V965. So if you have a root shell on the phone, you can issue the following command:
mount -o remount,rw /[email protected] /system/
Once you have done this, you will have read/write access to the system partition.
The only thing I then need to know is what should I avoid changing that may break the ADB bridge/root console?
And is all the UI stuff kept together, if so, where?
Shuffle it around a bit, make a new ROM

Thanks for the driver!
Unfortuntely it doesn't help
I found out the culprit, I tried to install gapps (google apps package) to the system app folder. I thought these changes would be reversed with a factory reset, but they are not. Setupwizard.apk keeps crashing and is preventing me from accessing my phone, so I must find a way to remove it from the system app folder. However, since this error occurred, I am not able to contact the phone in any way from the PC. Adb toolkit does not detect it, even when I reinstalled your driver. It's quite puzzling, I dont understand why in recovery mode I cannot connect adb-toolkit anymore.

Got my V965 working again, but it was a lot of hassle with shell access. Still not fully functional, no drives detected when i connect to USB, which is quite annoying, but not more than that. If you ever make any progress with google apps or flashing, please keep me informed, that would make this phone much more useable. I'll also keep hacking away at it, but without a bootloader unlock (I still think this is the problem), I don't think it will be possible.

I'm convinced it's possible to flash the phone, it seems they do it a lot in China.
I found a website with a couple of custom ROMs specific for the V965:
http://www.romjd.com/Rom/Detail/17086
And what I suspect is a rooting & flashing tool. Rooting works, I haven't figured out flashing yet.
http://dl.vmall.com/c0xa12brvo
I've also tried flashing from the settings - update menu in the phone, but it never finds the ROM (update.zip)
I did find another problem, I can't be reached on my phone, it always goes to voicemail. Same SIM in another phone works fine. No idea what's causing this.

Hi
I might be able to help you with the problem.
I have a mint, unused ZTE v965. I have used MTK Droid root and tools to extract a backup of the entire new phone. It is currently uploading to www dot nickhill dot co dot uk forward slash ZTE-V965_new_backup.zip
You should be able to write this back to your phone using flashtool.exe.
I don't know for sure if this will work, so entirely at your own risk! Just trying to help. If unsure, ask around.
I am new to this forum, so please remember to click the thanks button if you find anything I have done helpful!
Meanwhile, the MTK droid root and tools has a function to remove much of the chinese stuff (once the system has been installed) and there is always the cyanogenmod gapps package. This may be worth investigating.

Thanks for the ROM, i'll give it a go. I will try to install it using the update option in the settings, that seems the safest.
Be careful with gapps. setupwizard.apk + factory reset = a lot of problems (if you install in system app folder)

OMG that tool is awesome. created CWM boot, installed your ROM, then installed a clean ROM, then installed gapps, all working!!!

Firstly, I'm glad it's working for you.
Secondly, which tools did you use? Did you unpack the zip, open flashtools, select the scatter file then program the phone, or did you use some other method?
Which clean ROM did you then install, and how did you install it?
Did you then use MobileUncle to install CWM then use the cyanogenmod 10.1 gapps, or did you do something different?
It is useful to remember that MTKdroidtools has a useful function to remove chinese stuff. I think if more people contributed to the list of Chinese files that are safe to remove, that would be blade.
A detailed step-by-step guide might be helpful for anyone else with the same problem. One of the general problems I find is that there are plenty of guides around referring to this program, or that program, but few are detailed enough for someone who doesn't already know about those programs to use.
I pretty much bricked a Lenovo A766 yesterday, and it took several hours to learn about the tools to eventually unbrick it.
I would have rather spent my time understanding what is really going on, rather than spending my time learning vaguely what tool achieves what end result. If I understood more about the Android system, and built that knowledge on my understanding of Linux, I reckon I could achieve much more.
One thing I notice is that tablets and smartphones are actually replacing desktops and laptops. February this year, windows machines were down 7% YOY. I use Ubuntu for my main computer. Using these tools on Windows led me to significant frustration! This has led me to understand why there is a move. Maybe the tools provided for windows need to eventually move to android. We could then potentially use USB OTG to service other android devices. MTKdroidtools and flashtools runnng as a host on a separate Android system would be cool.

Did you give it a try yet? Another user did and google apps are working for him, so thats 2 for 2.
Are you still on your original ROM? If so, I have a question for you. Do you get notification badges on your icons, for instance, when you have a missed call, is there a red box with a 1 on the phone icon? Also, do your contacts get ID-ed when they call you? I have some problems with that, caused by the country code prefix. I am still running that ROM I downlaoded from the Chinese forum, but if your ROM doent have these issues, I will switch back ASAP.

Where are configuration settings stored accross factory resets?
I have come to the (perhaps erroneous) conclusion that the user interface and what the user will experience is governed primarily from:
the APKs in
/system/app/
/system/vendor/operator/app/
and the configuration files pertaining to the installed apps, which is located at:
/data/user/0/
I guess that when the android device is factory reset, the /data partition is completely cleared, right?
Is there a set of standard configurations which are unpacked from somewhere into /data/user/0/ after a factory reset, or is it normal for all configurations to be stored in their respective APKs?

[Completed] [SOLVED] Turn on USB debugging with black screen

Hi Everyone,
I'm using a Samsung GT-N7105. It has 16GB of internal memory. It has no external SD card.
A few days ago my phone's screen went black. Everything else works fine, including touch, just that the screen is always completely black.
I took it to a repair centre. After the repair centre ran some tests, (they kept my phone for 2 days,) they confirmed it was the LCD screen problem (i.e. a hardware issue). Since that LCD screen is expensive to repair, I chose not to repair it.
So now I want to install Android Screencast on my phone. I connect my phone to my desktop, and to my surprise I discover that USB debugging isn't enabled anymore!
So I call the repair centre and ask them what software changes they made to my phone. Their response is:
1) The partition table has definitely NOT been altered.
2) "Your Android version has not been upgraded."
3) "We used a special software to format your phone." They declined to tell me what software they used, and they don't seem to know which partitions have been "formatted"! But they did say that "format" was not the same as "factory reset".
(Btw the people at the repair centre are non-native English speakers, whereas my first language is English, so it was hard to ask about technical details.)
Therefore my best guess about the software state of my phone is:
1) It's running stock Android 4.1.2, which it's been running since the first day I bought it
2) The bootloader should have no KNOX nonsense
3) Recovery should be stock recovery
4) A few partitions have been "formatted" to unknown states
5) There are no longer any pattern, PIN, or password locks on my phone. If my phone is on and it's been sitting idle, I just have to tap the home button, then swipe the screen, and it unlocks.
I can reconstruct the partition table of my internal memory if you guys need it. I did an entire dump of mmcblk0 about two months ago.
(Btw the size of that dump of mmcblk0 is 15,758,000,128 bytes, which is significantly less than 16GB, even if you count by 1000s instead of 1024s. Unimportant side question, but does anyone know why?)
**************
My main question is: How do I enable USB debugging ON ANDROID with the black screen restriction?
I've searched the forums, and in thread 2395047 (can't post links yet) the recommendation is to flash CWM recovery to get adb access. But keep in mind that my ultimate goal is to be able to install Android Screencast on my phone, so that I can regain full phone functionality (with the help of an attached computer screen). I don't quite see how adb access via CWM recovery can help me to achieve this goal.
Also, I've never actually used CWM recovery before and don't know how it works. One of my concerns is: Once I have flashed CWM recovery, and after I boot into recovery, do I immediately get adb access just by hooking up to USB cable to the desktop? Or do I first have to select some setting, which would be tough to do with a black screen?
Thanks in advance for all your help!

Hello,
I've been dealing with android for a while and have been a member of XDA for a while. In my time here I've searched for a solution to this issue many times all over the web and XDA but never came up with anything useful.
Of the possible solutions I've found, the most likely possibility is to use an OTG cable and mouse to interface your device but this requires you to see the screen which is not an option for you. adb in this situation is only useful if you want to retrieve data from your device. I do remember finding something on the web that could potentially help you turn on USB debugging but I'm having trouble finding it now. I'll keep looking but can't promise anything. In the meantime, try posting your question in the forum linked below.

Hi Droidriven!
Thank you so much for taking the time to read and reply to my question.
Guess what, with the help of workdowg, I managed to work out a solution! My saving grace is that I'm running Android 4.1.2 and not one of the newer versions. My understanding is that if I was running one of the newer versions of Android, then I wouldn't even be able to get adb access via CWM recovery, because of the extra security measures. (Although I might be wrong about this point; I am still noob.)
I solved my problem in the following way:
1) Flash CWM recovery via ODIN Download mode
2) Boot into recovery, connect phone to desktop computer, open a command line terminal
3) Type "adb shell" to get a root shell in CWM recovery
4) In that root shell, type all the commands in the last code box at the end of the following post:
http://forum.xda-developers.com/showpost.php?p=63829295&postcount=27
(Much thanks to workdowg for this step)
5) Type "exit 0" to exit the shell in CWM recovery, then type "adb reboot"
6) Wait for my phone to reboot to Android
7) Type "adb devices", and now I see that I have adb connection to Android
After this, I was also able to successfully run Android Screencast with my phone. I can see my screen again!
So now, everyone please help me think of some useful search tags for this post / thread.

I'll have to remember that, I wasn't aware of the difference in 4.1.2, I've not had to deal with 4.1.2, that's good to know.
Glad you got it going, now see if you can find one of your devices on eBay that is no longer working in one or another but still has a good digitizer and glass, you may find one cheap, then you can use the digitizer+glass from the used one to fix the one you are using.

That's a really good idea, which I didn't even consider. (Maybe because I've never meddled with hardware before.)
Thanks!

[SOLVED] Android Trojan.Gorilla.AM or Guerrilla.AM on my device OEM launcher...

(NOTE: this post is a duplicate of a similar thread I started on the Android Central user forum)
Hello everyone,
In the continuing saga of the Leagoo T5C i bought before the holidays from GearBest, I've seen the good (the price and overall build quality, along with a reasonably good user experience), the bad (some notifications that I just can't get rid of, among other things), and I now present you the ugly: after watching a review video on YouTube about my device, I learned that it came loaded with a Trojan called "Gorilla.AM"...
***EDIT: apparently, the Trojan's name could actually be "Guerrilla.AM", I'm not sure.***
Needless to say, I did as the tester had, and installed Malwarebytes, which, sure enough, found the exact same Trojan on my device.
You can watch the video here: https://www.youtube.com/watch?v=R5l3z7BvBtk
It so happens that it's embedded in Leagoo's own application launcher, called Sujet (in French; maybe it's called "Subject" in English, I don't know). I can force quit the application, since I use another launcher called Apex (good pick, by the way), but Malwarebytes can't seem to shake the Trojan off my device nonetheless.
A quick search on Google gives very little in the way of information about this malware, but I'd like to be on the safe side, so I came here.
Any contribution would be welcome at this stage.

Hi. I've seen your post on a french-speaking forum but for my own reasons I don't want to help there, too many morons.
Leagoo is well-known for smartphones with built-in spyware/adware. I've had both a Z5 and a M5 and both had such crap in the stock firmware.
This one is new to me but you'll probably have to follow the same steps to get rid of it.
Try
Code:
adb shell pm disable <internal name of that launcher>
first (from a PC connected to the device with ADB - zillions of tutorials available for this)
The internal name can be found by guessing or by using one of the many apps that will show you the information. One is https://play.google.com/store/apps/details?id=com.csdroid.pkg
If that fails, try adding "-k -user 0" to the command line.
If it fails again (denied) then you have no choice but to root your device first, then use this pm command from a root shell or directly delete the folder for "Sujet/Subject" from /system/app or /system/priv-app where you'll find it.

Hi,
OK, first off, thanks for the reply. Secondly, as I've stated before, I'm new to Android, and though I know my way around the command line in both Windows, Linux et OS X (not so much macOS: my MacBook Pro is 12-years old...), I suppose there are some things to set up first, before you can actually do what you suggest.
I understand that ADB stands for Android Debug Bridge, so is it an existing functionality in, say, Windows, that you can trigger from the command line, or a third-party software you have to install first?
On the Android side, what action should I take? Any Developer command to enable/disable to let ADB interact with my device the way it's supposed to?

Yes, you need to enable debug mode on your phone too. I could refer you to one of the zillion tutorials available on the net, but here's a summary.
Go to settings > about... (à propos)
Make at least 7 rapid touches on the line that says "build number" or its french translation.
This will make a new settings menu available from the main settings page: developer options
In this new menu, enable USB debugging.
Then you need to install ADB on your Mac and I'm at loss to help you there because I'm totally foreign to Macs. Never used one.
This seems like a good start: https://www.xda-developers.com/install-adb-windows-macos-linux/
Note: you may also try issuing the commands mentioned above from a terminal emulator running directly on your Android device, although I'm told that it's not exactly the same thing protection-wise.
Install this: https://play.google.com/store/apps/details?id=jackpal.androidterm and try typing the commands from the emulator window. If it works, no need for ADB (although having ADB will probably prove useful sooner or later and I encourage you to take the step).
EDIT: forget the guys from Phonandroid, they're brain-damaged beyond help

OK, thanks for the heads-up; I've already installed a Terminal emulator on the phone, so I'm gonna give it a go in a moment. I concur about Phoneandroid, alas: I've just received flak from one of the moderators because I'd double-posted on the same subject, whereas I'd just posted one thread, in the wrong part of the forum, according to him. Go figure...

OK, please feed back on your attempts, both from terminal emulator and through ADB.
Alas, I suspect that root will be required. It was for me on my Z5 and M5 to get rid of Leagoo's crapware.
Phonandroid is a bunch of losers with bloated egos posing as experts when 2/3 of the replies given are total BS.

"Er, Houston, we've had a problem..."
On Windows: "ADB is not a recognized name for a command applet..."
On OS X: "adb: command not found"
Stumped, I am...

(Additional question, not quite related: Aida64 indicates that my device runs a 4.4.49 version of the Android kernel, when the current version for Android 7.x is supposed to be 4.4.1; how does that compute--no pun intended--with my issue?)

Missing adb command is because the adb.exe (Windows) or adb (Mac) file is not in the command path. Either make the folder that contains the adb[.exe] file the current folder using the cd command or use whatever context menu for opening a command line window within the currently selected folder works, or even add that folder to the PATH variable. Google "add directory to path" for Windows and MacOS.
No idea about the kernel version. Minor kernel versions may vary within an Android release. Not surprising and most definitely unrelated to your problem. The crapware certainly isn't part of the kernel. It's most likely a system app i.e. a folder within either /system/app or /system/priv-app folders. You can't delete it without root, but you might be able to disable (freeze) it with the commands I gave you.

OK, thanks. I did "cd" to the folder where I had unzipped ADB on Windows (on the Mac, when I tried to open the ADB executable, I got a "cpu not supported" error message in the Terminal, as I feared, since my MBP is 32-bit-only, and most Mac applications nowadays only support 64-bit CPUs), and still got the "adb unrecognized command" error in PowerShell.
The phone was plugged in, and the right USB mode, so I'm still a bit baffled here. Gonna try it again with a different approach. Will keep you posted.
Over and out...

OK, here's what I got: "Error: java.lang.SecurityException: Shell cannot change component state for com.leagoo.launcher3/null to 2"
Basically, from my poor understanding of how Android works, it's root or die, right?

I see that this phone has 7.x android. So, a Magisk Systemless flash might work. After rooting your device, get a good launcher integrate it to /system. Then delete your stock launcher all together.
Tell me if this works.

If you are new to this, use an app from play store for uninstalling and integrating apps.

Hi,
Yes, like I said, I'm a newbie when it comes to Android, so I'll abstain from rooting my device for now, but I'll keep your suggestions under advisement, because I suppose there'll be no other option in the long run. I'm gathering info on how to safely root a device.
I've done countless jailbreaks on iPhones, and it was always absolutely painless, but then, I had better understanding of how iOS works than I have Android, so until I know more about the OS, I'll keep my phone as it is.
Thanks again!

Jailbreaking vs Rooting is like 5-1 on difficulty level. Because Android is Open source while IOS is not. I would highly suggest you Root it if your phone does not have warranty. After all something that is on /system partition like your launcher will need superuser access to modify it. I cannot think of a way that wont void your warranty.
You can flash TWRP and then boot into aroma-fm but that will void your warranty. Rooting is the preferred option here.

Yeah, well, the phone is brand-new, and still under warranty, but that's not what's holding me back: I'd rather not brick it, most of all, because I need it, if not as my main phone, at least for connectivity.
I've read tutorials on this very website about using TWRP to flash a new baseband, but I'm curious about what firmware to choose, where to download it from to be sure it's not laden with bad stuff, and how sure I'll be to have an operable phone afterwards.

Why do you want a new firmware? I don't get you man, do you want to clear out the malware or try a new ROM? Because i think you would have to build a new ROM, there is not one available i guess.

That's the thing: the malware on my phone is part of the application launcher installed by the OEM. In other words, it's embedded inside the ROM. If I root my phone and somehow manage to get rid of this launcher, what's to tell me that Leagoo won't push it silently back onto my device under the disguise of an update?
I don't know what to do here. I understand that based on stock Android, each OEM applies a certain number of modifications to accommodate the hardware it used to build the phone, and since the SoC is brand-new, I gather there aren't many drivers available, unless I leave the current baseline in place.
I'm kinda caught between a rock and a hard place here...

If you use malwarebytes after root that thing wont happen. And almost all of the OEMs have a trigger which voids when rooting or flashing firmware. After that the OEM wont give you updates unless you use the A/B partitioning system.

OK, I understand how rooting my phone would void the warranty: after all, it's a substantial change in the phone software, and the OEM can't be made responsible for any mishap that occurs after I've rooted the phone.
What's the A/B partitioning system (I suppose it helps partition your storage space)? I don't have a microSD card installed (I use the slot for my second SIM), but I do have 32 Gb of storage space, minus what's already used up.
Do you know KingRoot? Is it as good and (reasonably) safe a rooting tool as they say it is?
