Is it possible to install gsi ROM t if buggy then reflash back to zui stock ROM without bricking the device and relock the device to China region to keep widevine L1 and for ota updates for the device.. If other region row wideviinev L1? Thanks
[Lenovo P11] mardon85:
I tried to do this tonight and for the life of me could not get my laptop or my desktop (Both windows 11) to see the 9008 port. I've installed the latest driver and it just sees it under EDL mode as "android" under other devices.

I'm on the latest version of ZUI, I wonder if Lenovo did something?

Anyone else done this process from the latest ZUI update?

Hi

I have a new Android device, it's not any of the ones that have their own forum.

More specifically it runs Android 11 on top of a 4.19.193 Rockchip BSP kernel.

I need to read one or two specific files but these files are only readable by root.

I have ADB shell access.

What I do want to acheive:-

Temporarily have an ability to copy a file that's readable only by root, this could be by some GUI app that copies files, as long as the copy is readable by normal user, running commands as root, copy a partition to an image file, export to a desktop machine and read it there. Any one of these would get me that file.

What I don't want to do:-

I don't want to permanently modify the device, unlock the bootloader, put su into /system or anything like that.

Does anyone know of a rooting app that can give me temporary root access but then doesn't actually change the system?

thanks
[General Questions and Answers] xXx yYy:
To get temporary super-user ( AKA root ) rights on an Android's device shell all you have to do is to find a suitable su binary and copy it onto Android's filesystem.

A: To run Android shell commands with super-user right from within the shell on desktop computer ( AKA Command Prompt ) you have to run within desktop computer shell

adb devices
adb push <LOCATION-OF-SUITABLE-SU-BINARY-ON-PC-HERE> /data/local/tmp/

what will 1. connect the Android device to your desktop computer and 2. upload the su binary in the Android device temporary directory always available for the user.

B: Then, in desktop computer shell type

adb shell "cd /data/local/tmp & chmod 776 su"

what makes the su binary executable: its ownership by default is set to shell.

C: Then in desktop computer shell type

adb shell "ls -l"

what will show you content and permissions on recently uploaded files.

D:

To apply a series of Android shell commands what require super-user rights you now would run

adb shell
export PATH=/data/local/tmp:$PATH"
su -c "<SHELL-CMD-HERE>"

....

su -c "<SHELL-CMD-HERE">
exit

BTW:

When in an Android shell another process like su gets started then this spawned process runs as a child process means it inherits most of the parent process attributes.
[General Questions and Answers] dieselnutjob:
adb push allowed me to send the file

adb push su /data/local/tmp/
su: 1 file pushed. 1.2 MB/s (11640 bytes in 0.009s)

but the adb shell command is failing

adb shell "cd /data/local/tmp & chmod 776 su"
chmod: su: No such file or directory

if I then log in over adb I don't seem to have permissions to do anything in data

adb shell
ls -al
drwxrwx--x 47 system system 4096 2022-09-02 16:31 data
cd data
ls -al
ls: .: Permission denied
[General Questions and Answers] dieselnutjob:
additionally, I thought that su would need the suid bit set

Does chmod 766 acheive that?

[General Questions and Answers] dieselnutjob:
The device has separate boot_a, boot_b, dtbo_a, dtbo_b partitions.

If I could be reasonably sure that booting a boot partition from a similar device (I have one) would pick up the dtb from this device then I think I could be reasonably confident of not frying anything, I might try and boot it from fastboot.

[Redmi Note 10 Pro] wuslschweiz:
Hi Guys

Until now I never used a TWRP Backup I took and restored it. Therefore this question:

I am right now on LOS19.1

Is it possible to take a full TWRP backup

- metadata

- Data

- Boot

- Cache

- Dtbo

- EFS

- Modem

- Super

(all except Recovery)

Then Flahs MIUI 13.8 test something (If Google Pay is working there) and when I am finished testing just restore the full TWRP backup und my phone is on the same state as it is right now, without loosing Data?
[Redmi Note 10 Pro] NOSS8:
Restoring an AOSP rom to a Miui rom will not work and vice versa.
[Redmi Note 10 Pro] wuslschweiz:
Thank you for your reply
[Redmi Note 10 Pro] wuslschweiz:
Hmm, why does it not work?

Or does someone know a link with some detailed information about android and roms?
[Redmi Note 10 Pro] NOSS8:
Not the same OS(google and Miui).

Use one or more third-party apps for ,sms,mms apps.

It's as if you wanted to restore a Miui backup on an apple (I'm talking about the system, etc, of course).
[Redmi Note 10 Pro] HiQual:
I am not sure we have fully understood the question. I think the OP might be saying he will test MIUI and if he does not like it can he safely use the TWRP backup to go backwards and fully restore LOS 19.1 fully working as before ? ?
[Redmi Note 10 Pro] wuslschweiz:
Ok, thx

So if I understand right, when I am on MIUI I can flash LOS19.1 over it and on this LOS I can restore the twrp backup I took from my actual LOS installation and I am back on current state?
[Redmi Note 10 Pro] NOSS8:
Yet I wrote "Restoring an AOSP rom to a Miui rom will not work and vice versa." It seemed clear to me since there were no objections.;)

Restored to the same rom should work but sometimes TWRP is finicky.
[Redmi Note 10 Pro] NOSS8:
If you back up systems etc on los 19 and install los 19.1 it can't work.
[Redmi Note 10 Pro] wuslschweiz:
Yes you are right 😊

Had to flash roms to often during last weeks und I am tired of setting it up again. I just have paranoya 🤣

Just want to get that dmn google pay to work

But thank you for your patience!
[Redmi Note 10 Pro] NOSS8:
For Google pay to work, you must take a certified rom or root and use Magisk.
[Redmi Note 10 Pro] wuslschweiz:
Are LOS19.1 or CrDroid8 not certified?

Does Google pay not responde with an error message if the rom is not certified?

Which Magisk module do I have to use?

When I install the SafetyNet check app it says passed.
[Redmi Note 10 Pro] NOSS8:
I can't really answer you, I don't have this device and no AOSP rom currently.

To find out if the phone is certified with the rom installed: play store/settings/about.

Even with a certified rom sometimes google pay does not work but usually the Op reports it.

I was using Magisk settings Hide.
[Redmi Note 10 Pro] wuslschweiz:
Thx, I will give it a try
[Redmi Note 10 Pro] Laptapper:
Los is passing safety net.

With magisk and right settings also.
[Redmi Note 10 Pro] wuslschweiz:
I assume on your LOS phone, Google pay is working?
[Redmi Note 10 Pro] Laptapper:
Can't say. No NFC and don't use pay
[Touch HD Accessories] dsm52:
What are the chances that the 1500mAh battery that comes with the MAX 4G would fit into our Touch HDs? The MAX is slightly thicker than the HD which may explain the bigger battery though..
[Touch HD Accessories] ez2remember:
Yeah that would be nice... I wonder if the battery connects are in the same place. If so the battery may work but probably bend or bulge our battery cover.

Another problem is where do you buy the max 4g battery from?
[Touch HD Accessories] iouri_2008_HD:
No chances, different dimensions. I see them.
[Touch HD Accessories] tboy2000:
That sucks. I was wondering the same thing.
[Touch HD Accessories] chuckie0530:
heyhey,

I am from Hong Kong, and I got my HD yesterday.

I also bought a replacement battery incase my HD runs out of battery~

I think it is a Japanese brand, and the battery comes with 1500mAh!!

google it and u might find it!

~cheers
[Touch HD Accessories] ikkezelf1:
Got myself a 1500mah battry from ebay.

It fits and works.

was hoping for an even bigger battry, cause the difference between 1320 and 1500 isn't that much.
[Touch HD Accessories] ctohang:
May I know the brand and how much is it?

Thanks!
[Touch HD Accessories] JohnQ:
i bet its momax. its HK brand. im using it. also 1500mah. not longer than original one.

but its ok to be a replacement....so far so good
[Touch HD Accessories] Begovaya:
Gotta be careful with batteries of unknown sources.

Surely there are many good and cheap stuffs made in China, but more often you find cheap and bad items.

From my experiences, these low price batteries are short-lived, with wrong mAh parameters, and worst of all, may cause damage to your precious phone. I'd better buy an original one (or wait for it to appear...)
[Touch HD Accessories] ednap:
I'm also using a second 1500 mAh battery from eBay without issue. Does last longer than the original 1300 unit as I can compare because I swap between the two on extended trips away from the office.

how long apps survives in the background?
[Vivo X80 Pro] waldoud:
Hello, thanks for answering, from what you managed to notice, some between 2 and 3 hours, others last a little longer like wahtsapp that is every two days
[Vivo X80 Pro] Pervokur:
try this through adb shell

settings put global activity_manager_constants "service_max_inactivity=50000000,power_check_max_cpu_4=5"
[Vivo X80 Pro] waldoud:
Great, thank you very much for your answer, I will try and tell you, in theory, what does the code do?
[Vivo X80 Pro] Pervokur:
if app doesn't do anything in the background then it will be killed after service_max_inactivity. Removing battery optimization will not force app to do something xD
[Vivo X80 Pro] waldoud:
ok I understand, thank you very much for your help I really appreciate it a lot, I'll be commenting on what happens
[Vivo X80 Pro] waldoud:
the code when entering it in adb says that it is not recognized, anyway thank you very much for your help
[Vivo X80 Pro] Pervokur:
because first you need to execute "adb shell" and then "settings put"

otherwise

adb shell /system/bin/settings put global activity_manager_constants "service_max_inactivity=50000000,power_check_max_cpu_4=5"
[Vivo X80 Pro] waldoud:
done should I reboot?

no

Hello Cruizertz, I have the same device but 1g/16g

In the radio app can you save the stations and not delete them when you turn on the device again?

First unzip the folder, and just copy the Update folder (inside there are more folders, don't touch). Second, put the Update folder on a flash drive and insert it into the USB² (you have two USB ports on the headunit, must be with the number USB².

Third: the system asks you if you want to update, you must give OK or wait 5 seconds. The copy of the files will begin, do not touch anything, and you will see how the lights blink

Fourth: do not touch anything, when the update is done the unit will turn off, and when it turns on again the lights will continue to flash, and after about 30 to 60 seconds it will start updating again. Never remove the flash drive or touch anything until the message appears at the bottom indicating that the update has finished.

When you're done, tap ok. Everything has been deleted from the headunit, and you must reinstall everything you had before.

Important: if you had the Apps from a vendor, such as Podofo or Jancar, they are deleted. If you had any map App too, but if you need Here Maps tell me.

Thank you very much for your help meidland. I was able to search for a moment and have installed it and everything is working perfectly.

How to use wireless android auto?
[Android Head-Units] gedster314:
Oops, responded to wrong one. Will get to yours in a bit. Don't remember exactly, I tried so many things trying to accomplish various things. Let me poke around my device a bit to refresh my memory on the Bluetooth AA aspect.

I unzipped/unrared it. Moved it to a usb thumbdrive. Stepped into the first layer of folders, there will be one folder called something like 'autoupdate', move that folder to the root layer of the thumb drive. Inserted thumb drive into one the headunit's hangy down USB ports. Opened the headunit's file manager and gave the headunit a minute and it popped up with "do you want to update?" It's then like 20 minutes with a couple reboots. My experience was painless and uneventful. Wish getting the AC vents to fit the fascia well and the fascia to fit the dash well went that easily.

Don't expect a performance bump. The unit is painfully slow with Google Maps but Android Auto is pretty zippy. For the grief this Hikity kit gave me, just having Android Auto over the stock headunit with Bluetooth Aux in adapter made it all worth it.

Next time, I think I will stick switch Kenwood, Alpine or Pioneer. Atleast they have some form support.

Thanks again XDA people. I've been away a long time and got out of my phone hacking phase. Good to see you guys are still hard at working on making Android devices better.

I

I think the app is called z-link or something.

You dont have to do anything to connect AA to the HU.

Just have your smartphone connected to the HU's bluetooth.

Try to forget the HU bluetooth on your smartphone and maybe the HU's hostspot.

Disable bluetooth on smartphone, enable it back and connect the the HU.

AA should popup soon after, without starting anything on the HU.

In case you messed with WiFi settings on the HU, try to revert them.
