[Q] Fake Samsung Galaxy S3 problem

Hi guys,
I have here a fake samsung galaxy s3
After hours of searching I finally figured out that my phone is an MTK.
MTK Soft Ver: 0x1220
MTK HW Ver: MT6250
OS: MTK52D
Model: J5001
I wanted to root this phone but there is no development settings so no usb debugging option either..
Basically I want to put a new OS on this phone but I'm stuck not knowing what else to do to try rooting this phone..
What can I do to put a new OS on it..
Any helpful information would be much appreciated!

Nobody has a clue?

Does it run Android, and if so, what version? If it's 4.2+, then you need to repeatedly tap 'Build Number' in your about phone page of Settings.

Using *#66*# you will find something like this (and factory tests):
VERSION SUMMARY: YLXJ5001_11B_272_Y7_ML10

DSP PATCH: 1.0

But nothing more to do from this point... This device is a shame for me, I can`t do anything.

[Completed] Please Help Me (I am severe problem with my Android Tablet PC video recording)

Hello,
Awesome XDA developers. I am seriously in need for some helping hands for my Tablet PC. I have got a China Octa Core 7 inch tablet pc with WUXGA display, MT6592 Octa Core processor, 2GB RAM, 16 GB ROM, Android 4.2.2 OS , 13.3 MP REAR CAMERA, 5.3 MP front camera etc.
So far the tablet is so good with Android 4.2.2 OS. The china company recently gave me an updated ROM for the tablet PC. The update includes Android 4.4.2 OS. I installed the firmware with SP Flash tool 5.5. After installing the OS, I was very happy to enjoy KiTkaT. Every thing were perfect.
Except one strange problem I am facing with Android 4.4.2 KiTkaT upgrade. I can take photos in 13.3 MP high resolution with the rear camera. But when I record videos with "Fine" recording mode or any other modes (low, medium high or fine), the video gets recorded in 640x480 low resolution only. I tried every camera settings did not work. I also check the "build.prop" settings & "camerasize.xml" settings. But nothing worked. For both the front (5.3 MP) and rear camera (13.3 MP) records videos in 640x480 low resolution where as the same camera take photos in 5.5 MP (Front Cam) & 13.3 MP (Rear Cam) resolutions.
But for Android 4.2.2 OS, both the cameras could record videos with 1920x1088 resolution when you choose "Fine" as the video recording mode. I am a beginner level developer. I can not get anything to fix the problems. I reported this to the tab company, they said the firmware company can not fix the problems now. And asked me to use the Android 4.2.2 OS. I have also googled for possible helps with this firmware problems. I found that modifying libcameraservices.so & media_profiles.xml may fix the problems. I found the file "libcameraservices.so" and copied to my PC, opened it with a HEX Editor but am not that expert to correct it. Please help me.
Can the XDA forum experts help me with this miserable problems. :crying::crying::crying::crying::crying:
Please help. :crying::crying::crying::crying::crying::crying:
Thanks & Regards

Those are libraries that are included in the firmware. Those can't be edited with a Hex editor. Not effectively anyway. What I'd suggest instead is to see if you can install Google Camera App.
But if that too does not work, then for you, the only other thing might be going back to 4.2 short of rebuilding the firmware with right libraries.

Tried Google Camera But Failed

Thanks for your quickest reply to ma text.
I installed google camera. After getting it installed from the play store. It closes with an error when I try to access the camera settings. I also tried to do a trick by copying the "libcameraservices.so" from the Android 4.2.2 firmware & then copying it over the "libcameraservices.so" Android 4.4.2 firmware. Then I rebooted the phone, but it got stuck in the boot logo never rebooted.
Is there any possibility to correct the parameters of libcameraservices.so (Android 4.4.2 firmware) to fix the error..?? I am not that expert in building a custom ROM yet. Can you please help me out..??

Here is the libcamerservices.so for bot Android 4.4.2 & 4.2.2
Hi,
I am upload the "libcameraservices.so" file that I copied from the both the fimware system files. Is there any expert who can check the difference between these two..?? And correct the parameters so that it is possible to record video in 1920x1088 resolution for Android 4.4.2 OS as well.
Thanks & Regards

MTCD PX3 with android 7.1.2 - downgrade for rooted rom?

Hi!
I have a PX3 MTCD (XRC) quad core 2GB with android 7.1.2 nougat
nougat is nice, but i'm wondering if it is really necessary to have the latest android offering on these units?
would there be a benefit to downgrading to a rooted Malaysk 5.1 rom?
I'm looking for speed and reliability.
Usually I'll have the following running:
nova launcher
neutron for music player (my music is all FLAC files which neutron plays.. also neutron widget is great/stable)
or sometimes pandora
navigation: google maps, sometimes waze
when not actively using navigation apps to get anywhere, i'll have MiniMap overlay on the left half of the home screen and pandora/neutron widgets on the right, just below a Google Now widget (shows weather and some important info)
minimap overlay: https://play.google.com/store/apps/details?id=com.teqtic.minimap&hl=en (very cool floating/re-sizable)
I've got a mobile jetpack in the glovebox for data (not sure I can recommend this if you live someplace hot)
Here are some specs of the unit I've got:
CPU Rockchip 3188 Cortex A9 Quad core
RAM DDR3 2GB
Flash 16GB
GPS SIRF III
Loader FORYOU DL-30
Amplifer IC ST TDA7388
Radio IC ST TDA7786
Bluetooth 4.0
Resolution 1024*600
Max output 4*50W
Main Frenqency 1.6GHz
So should I stick with 7.1.2 or would there be much more benefit for speed/customization/?? if I downgrade for rooted rom?
Thanks!

Do you installed the Malaysk rom? I have the same system and i want to downgrade it, but im so confused because ther's not a lot of info. for px3
Please tell me if u do it

Hello there
have you figured any way to root ?

I'm +1 for the rooting question as I have not figured any way to do it yet.

I have pretty much the same unit, for my Kia optima. I tried to install malaysk's rom and recovery asked for nupdate.img, not dupdate.img like all these other threads specify. Even renaming the file to nupdate didn't work, told me invalid firmware. I have another thread asking for advice, but it hasn't garnered a response.

I have the same unit. Do you haven any problems with the car control app?

Has in the meantime already someone have found away to root the HU?
I have a similar MTCD_KLD_V2.58_1
and also look for a root solution

XRC Root Solution
Hi All,
Might have something that may help. An img file provided as a root solution but A-Sure (another supplier on the list) but I cannot get it to work I either get a partial file or a complete one. I cant post links due to my current post count but if anyone want the file to check out and maybe figure out where I am going wrong you are welcome. Drop me a PM and I will pass on my G-drive location for the download
Mine is MTCD_XRC_2.54a_1

Here are the details on my HU
64Bit Octocore - Coretex [email protected]
2GB
MTCD_XRC_V2.54a_1 June 16 2017
Branded under A-sure, this is a dedicated shell for an Audi TT
Many issues as with many of these HUs
No steering controls
Partial Bluetooth support
Doesn't recognise 4G USB Dongles

@Whizzbangles
Hi,
I have the same unit as yours mounted in my 2008 audi TT mk2 and everything works perfectly : bluetooth, steering wheel control, usb sticks...
Didn't try to root or change anything yet. Only issue is "Audroid auto apk I downloaded (not present in my Play Store) is not working.
Still discovering MTCD world...

I would be interested in your settings around the canbus and also just a check on how you have set up the wiring.

I just rooted my mtcd_kld_v2.58_1 with KingOroot. I then upgraded SU to SuperSU and uninstalled KingOroot while still retaining root. Its in one of the threads in this forum.

Yes, Kingoroot does the job. I am still however struggling to get my MF730M working.

Ah, thats the one that crashes on startup. Shame.

It crashes on mine too. Rk3188 px3 with 2gb of RAM. 7.1

Im running the px5. Does it install superuser and give you root? If so, you can install supersu after and uninstall kingoroot and superuser, leaving root with just supersu.

The RK3188/PX3 2Gb N units use a slightly modified SoM compared to the older RK3188/PX3 1Gb L units (the motherboard is the same). @Hal9k_ managed to get the N ROM to work on the older board simply by altering the partitioning so it should theoretically be possible to make the L ROM run on the later units as well.

Need a help in finding the right software update for my HU

I need to find the proper android 9 SW update for my below HU as it keeps restarting out of sudden :
Model : Rockchip PX5
Android version : 7.1
Resolution : 1024x600
Build No. : MXC89L-release-keys-20171229-V8.0
MCU version : TP66H4 4.24.1
APP version : TP66H4 20171207 .0.0.42
Thanks in advance

Your unit is not an MTC(D/E). Try searching forums for TP66H4, or posting/request thread moved to Android Head Units forum for greater exposure.

MTCE Head Unit resolution problem, no usb, how to change DPI

Hi All,
I have a MTCE unit in my car.
With some tinkering I've managed to unlock its potential, Swapping the launcher, customizing a bit and so on.
The only thing that bothers me a lot is that the units DPI or resolution is ridiculous, every app is barely usable everything is huge.
the units screen is 800x600
and this is its info:
Code:
Model
A-MEDIA AUTO (800x480 O)
Android version
6.0.1
Core version
3.10.0
[email protected] #1320
Build number
px5-userdebug 6.0.1 MXC89L user.hct 20180130.142324 test-keys
MCU version
MTCE_HZC_V2.75b_1
CPU
8 core 64-bit CPU Cortex-A53 @ 1.5G
Memory
2000 MB
after searching the forum and the internet:
there is no obvoius usb connection for ADB, or wireless ADB
only 2 sd slots and a mini usb connector that apparently doesnt even work
no root.
no secret menus with passwords in settings
is there any way I can change the DPI on this thing?
any help would be greatly appreciated.

Your question is much better posted here: https://forum.xda-developers.com/f/mtcd-software-development.7379/
I´ll ask a mod to move it to there. May be have a look around there.
BTW: You really need to upgrade your unit to at least Android 9.

It has a bit issues with the Memory, but I think it would work fine... and you would be able to root, or use a custom ROM with it.

The resolution is changed using the dmcu.ext file. Choose the resolution of your inclusion, copy dmcu.ext to the sd card and update the MCU.

If you want to update the MCU, then yes. Before updating, save the settings in the dmcu.cfg file, it is a backup of your settings, in case of problems with dmcu.cfg, you update the MCU and everything will return to the original settings. Factory settings/126/EXPORT, you can find the file in the root directory, take good care of it, save it to external storage.
