Problems with WiFi & Recovery with rk3036 board used in Mega Drive Flashback Consol

Hi guys,

I am a (bad) developer who is trying to obtain the maximum from the recently released Mega Drive Flashback console.

It is an Android 4.4.4 unit with an rk3036 SoC. The problems I am facing are 2:

1 - WiFi module seems not to be laoded and all .ko modules present in /system/lib/modules give "invalid exec format" for the exception of the mali.ko (gpu) one (when instmod it says "already present"). I would like to know what I have to do to find/build a correct wifi module; reading on the web it seems to be a kernel-related problem so I need to recompile the .ko or find another kernel or find a precompiled .ko which "fits" with the used kernel. I found other kernel.img, system.img and boot.img from other Rockchip devices but I do not know which .ko file to "reuse" (wifi.ko ?). Which WiFi USB dongle do you suggest me for this "challenge" ?

2 - I "stole" a TWRP 3.1.1 from an Android TV firmware using another Rockchip SoC and it is booting fine (I cannot control it via touch screen because the Mega Drive Flashback has not a screen but it is controllable via mouse) but it seems not to recognize/mount any console partition and the mounted ones (the ones present inside the recovery) are 0 bytes and I cannot save options. Can someone help me in making this recovery in a working state ? If needed I can post the recovery.img file.

The device is correctly rooted with SuperSU and has Busybox installed. ADB and MTP drivers are working fine.

Sorry for all those noob questions but we are trying to describe how the console works; you can find what we found out here: https://mdfbrew.org.

Hi, since our Mi A1 display is quite pale (and color calibration is inaccurate), it would be fantastic to have KCAL support in order to use for example Kernel Adiutor to calibrate the screen (as we can do with Redmi Note 4 global on Lineage OS rom with patched kernel). I have tried with Color Changer Pro but it's pretty limited (saturation change give poor results).

Now that the sources are released (even if nougat-based) , it will be easy to apply using the guidelines in this post https://xdaforums.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080 ?

Thanks in advance :)

PS: sorry if it's quite similar to a mine old post, but I have posted it in the wrong section last time, so I please mods to cancel the incorrect post.
[Xiaomi Mi A1 Questions & Answers] murtaza1326:
well it's too early to demand anything in kernel as far as i saw devs here all are in try to make custom roms well I don't think it is much necessary (we are on stock already) we need custom kernels first so if a one developer should work only to make kernel source stable it would be great and yes this features would be implemented but we have to wait

in a month we can get android 8.0 stable kernel and OS i think
[Xiaomi Mi A1 Questions & Answers] itsnie:
Mod please lock this useless thread
[Xiaomi Mi A1 Questions & Answers] dying_sun:
I don't think it's an useless thread, because kcal support is added in every custom kernel and it's quite used worldwide. If it's useless FOR YOU, it's not my problem.
[Xiaomi Mi A1 Questions & Answers] alkesh95:
Just off topic.

If it's in every custom kernel then your request and this thread are useless.

Won't you agree.
[Xiaomi Mi A1 Questions & Answers] ivomin:
Pale?!... wtf... just made a comparison with my old lg g3 and it's 1:1... except for the low dpi.... are you sure it's not a hardware problem... otherwise.... yes KCAL would be great....
[Xiaomi Mi A1 Questions & Answers] dying_sun:
Off topic? Thread it has been moved by mods. Anyway, since no custom kernel is available yet my request is to modify stock kernel in order to have KCAL support, I have seen all over XDA more useless threads...

I have seen hundreds of mi a1, screen is far form perfection, colors are under saturated and contrasts are poor. G3 had poor colors too. Redmi Note 4 has the same problem (and a quite similar panel), but with kcal I was able to do big improvements to the screen. I attach an example.

LEFT -> Redmi note 4 calibrated RIGHT -> Mi a1 hope you can appreciate the difference, it's not easy to show it in camera
[Xiaomi Mi A1 Questions & Answers] alkesh95:
My post was off topic not your thread.

Second i am aware of the benefits of kcal.

Just read my post again.
[Xiaomi Mi A1 Questions & Answers] ivomin:
I see what you mean... still i don't think there is much of difference for an ordinary usage.. for such low level device I don't think we (I) should have expect anything different and in the end ... it is still an old IPS technology so for really sharp and accurate colors - AMOLED. In the end it is a matter of taste and as this device is yours you should be able to modify it up to your taste. :)
[Xiaomi Mi A1 Questions & Answers] _mysiak_:
I find colors of mine very close to what Nexus 5x delivered, which was supposed to be very accurate. AMOLED is usually anything but calibrated, punchy & nice, but not accurate. But there seems to be a great variation of different LCD panels in Mi A1, so I was probably the lucky one.. :)

[Nexus 5X Q&A, Help & Troubleshooting] Artur98:
Hello,

in display settings on Android Oreo there is an option to change display size and i allways have it on "small" but there is a problem with one app that seem not to adjust to this settings and it is impossible to use it because all buttons and text are deformed and they overlay on each other. The problem disappears when i change the display size to "default". So here comes my question: is there any way to keep overall display on small and somehow make it change automatically to default only for this app?
[LG Stylo 3 Questions & Answers] technobe:

[General Questions and Answers] Muniappa:
since acer iconia B1-850 has 1 gb ram android GO would be a better option.

Has anyone tried installing it ? Is it available firstly ?

if so where can i get it
[8525, TyTN, MDA Vario II, JasJam General] torontotytn:
Hi everyone, great forum - and my question comes right out of the box. I recently got a 8525 for Rogers Network - and I am charging it. The LED goes from Orange to Green - but it won't turn on.

Do I have to wait until it's fully charged to turn it on? And does it need to have my SIM card in as well for it to turn on. I'm thinking I was given a Lemon.

What you think?
[8525, TyTN, MDA Vario II, JasJam General] BBowermaster:
It will turn on without a sim card. Are you holding the button in when you try and turn it on?
[8525, TyTN, MDA Vario II, JasJam General] torontotytn:
I had to do a reset to get it going - i got it slightly used for an amazing deal - i am starting to see why now.

The power button isn't working
[8525, TyTN, MDA Vario II, JasJam General] alkizmo:
that's REALLY not good.

You need that button to work to turn ON/OFF the screen allllll the time.
[8525, TyTN, MDA Vario II, JasJam General] torontotytn:
I am getting a swap done on the phone - so no problem. Thank you all though!

Another question - if i have wifi set up in my house - and i want to make sure the device won't pick up the Roger Network and start charging me - is there a way to turn off that feature.

So if I am at a hotspot - it will automatically go there and not the rogers network?

***EDIT: Nevermind - just have to hit the call button.***
[8525, TyTN, MDA Vario II, JasJam General] BBowermaster:
Download Modaco NoData. You can toggle Roger Network connections on and off.
[8525, TyTN, MDA Vario II, JasJam General] torontotytn:
Really?? I'll check it out - thanks man.

Another question - sorry for so many - and this might be a programming thing. But is there a way to have the phone option as a shortcut on the today/home screen?

Or even make it a soft button option?
[8525, TyTN, MDA Vario II, JasJam General] XtreMe_G:
there's already a shortcut to the phone in the start menu, so u can just choose that to be one of the aps in the home screen. the shortcut is real descriptive too.........its called phone
[8525, TyTN, MDA Vario II, JasJam General] torontotytn:
LOL - I saw that - I was looking for something that I could get at one handed without accessing the start menu.

thanks though

Edit:

Nevermind - hitting the call button brings up the phone. Nevermind..
[8525, TyTN, MDA Vario II, JasJam General] XtreMe_G:
hehe :p

welcome to the forums.....there's loads of information everywhere in these forums so pls spend some time reading so you dont turn ur phone into a brick
[8525, TyTN, MDA Vario II, JasJam General] torontotytn:
Will do - thanks man.

[Galaxy Note 4 Q&A, Help & Troubleshooting] mnmspis76:
Hi guys, sorry if this is a super silly question but I haven't been in the rooting game since 2007 and lost touch with a lot of things.

I have a note 4 SM-N910H with base version N910HXXU1DPC1.

Trying to downgrade because of all the issues with 6.1. Don't mind if it's official or custom rom (provided it's a super stable release). Thing is, I can't find a rom with the same base version number.

Question is, does it matter or can I just go by the model number alone?

If someone could point me to the correct links I'd very much appreciate it.

Thanks

Any guides to relocking bootloader and restoring to stock on EU version of V30 ?

Thanks in advance.
[LG V30 Questions & Answers] R800x_user:
Should be as easy as using the "fastboot oem lock" command
[LG V30 Questions & Answers] ChazzMatt:
Any reason you are doing this? The stock debloated, tweaked ROM in development section should give you all the features you need. You can also flash KZD without relocking bootloader.

LG still has a record that you unlocked your bootloader so it's not like they don't know.

Yes, these are the commands i used to lock the bootloader again (note you have to setup the device again)

adb reboot bootloader
fastboot oem lock

[LG V30 Questions & Answers] Gegobite:
what about the rom?

so when i do lock the bootloader, does the software get checked or updated or do I have to install it manually... what happens after i run all the commands in adb? Im currently on LineageOS 15.1 (LG-h930) :p

Question I ran fastboot oem lock and now I'm bricked with "your device has failed a routine safety check and will not boot" Does anyone have the fix for this?
[LG V30 Questions & Answers] me2151:
You need to be on a stock KDZ(literally 0 changes) before locking. try booting to download mode by turning phone off and holding Vol+ and plugging into a computer. Then flash a stock KDZ.

20e is the latest KDZ for US998(i assume thats what you have considering thats what is in your Signature). Use the LGUP_common_DLL_V30_ALL_VARIANTS attachment(there is directions in that thread on how to use that DLL).

[LG V30 Questions & Answers] kanehun:
Happened to me as well. Do NOT use uppercut method, as it is not working on Oreo. Instead use lgup dev method. It is working.
[LG V30 Questions & Answers] runningnak3d:
As [MENTION=4555111]kanehun[/MENTION] stated, you must use the patched LG UP, and you must use partition DL mode (select all partitions) -- upgrade or refurbish won't work.

If you don't want to wipe your phone and just want to get it to boot again, only select recovery, boot and system and make sure that you are using the KDZ for the version that is on your phone. You should be able to salvage your data if you need to.

[LG V30 Questions & Answers] charliebigpot:
Does relocking the bootloader basically unroot the v30?

If not, is there a way of unrooting a US998?
[LG V30 Questions & Answers] ChazzMatt:
If you JUST relock the bootloader you are going to cause LOTS of problems, UNLESS you first restore full stock firmware. Possibly even bricking your phone.

1) You want to flash stock KDZ via LGUP, which replaces TWRP custom recovery with stock Recovery.

Use "Refurbish" or "DL Partition". Then you no longer have root.

2) You can also relock the bootloader AFTER that -- if you wish to get rid of unlocked bootloader warning.

But step #1 will "unroot" your phone.
[LG V30 Questions & Answers] Septfox:
Completely different operations.

Unlocking the bootloader allows custom software to run because partition signature checking is skipped. This is what allows flashing and running non-LG ROMs, custom recovery, etc.

Manufacturers don't want you doing this because it enables updating the device once it hits planned obsolescence; they want you to give them another $800+ at that point, not keep updating what you have.

An example I like to point out: the Motorola Droid 4 stopped being supported at android 4.3 (Jellybean). Thanks to Safestrap - the bootloader is permanently fused shut but an exploit allowed loading an entirely different kernel and ROM via kexec after the stock kernel startup- and some particularly determined developers, it's running up to 7.1 (Nougat). The kernel is ancient at this point and spackled together with pieces from Amazon devices, and the phone is a bit slow using a modern O/S because it only had 1gb of memory, but it still works and people still use it as a daily driver because they like it. Last CDMA landscape QWERTY phone and all.

Root privileges are part of Android itself; think of it a combination of Administrator and TrustedInstaller account privileges from a Windows PC.

Google doesn't want you rooting because of the myriad ways the average user can ruin their Android installation by screwing with system files, the many security implications (easy example: let the wrong app have root, now the app has access to any data on the phone it wants and can manipulate whatever it likes), and it making it a lot easier to do things like block ads system-wide.

TL;DR bootloader unlocking is more device-side that disables certain "security" checks to allow booting non-OEM software. Rooting is software-side, lets you use the Admin account in Android for any number of useful shenanigans. They are independent of one another, but depending on the method rooting can prevent a locked-bootloader device from booting.
