This is from 2016. Do you think is still valid?
Re-read my post. I did NOT say that the thread I linked to was the ultimate or current guide. I advised to look at LOS as they had current guides.
The XDA threads started a long time ago, but they are good if you get a problem along the way. ie the instructions in the OP are outdated
I specifically said the OP instructions were outdated!


Firstly I need some foundations to start moving forward. I would like to start by replicating one of the ROMs that I already know, are working under my device. Basically I want to start with the premise the if someone did it, I could do it again, before I venture in "new devices" into the unknown camp.
And thats why I suggested reading the how to build LOS. They probably have the largest device coverage, and have instructions for each device. So if your device was "kirin"

But if you look at the base GIT pages for a custom ROM they usually also have instructions on how to build, but not normally device specific or as thorough as LOS. Did i mention you better get comfortable with GIT...

I think I could build from sources and all that without issues, but I don't really know where I must be touching and tweaking things to make things work. I have 0 knowledge about this topic.
Im not sure how little you know about programming or how much you wish to modify the ROM, so thats like asking how long a piece of string is. READ! where to tweak is going to rely heavily on programming ability. oh, and READING

I have a LG V30 Plus, Docomo Variant (L-01K).
Recently it started showing that annoying "charging blocked due to moisture" error.
I found a way to disable it by going into the hidden menu on one of the forums but I can't get into the menu because I don't know what model number to write at the end.
Typing "01" doesn't work, can someone please help me out? Also it keeps on saying "unable to operate".
Hi i need your help, I flashed a custom ROM and now it doesn't work well so can you please help me to get the LG v30+ L-01K firmware .

Hi Any Chromecast Receiver App That Work With Phones? The Google One
I don't exactly understand what you are asking, but there are no apps that will act like a Chromecast on your phone. There are video and music apps that you can share with someone with the same app however, so that you can watch/listen to the same thing at the same time though.

im really noob, want to asking about memu emulator. my PC spec is low, already using memuplay 7.6.6.0, feel stable, and already removing any bloatware. only for playing AOV.
but when i updating AOV, i cant login on in-game web page. because maybe memuplay webview is not support it.....
I try updating or changing manually using latest google webview and bromite webview but its say cant install because conflict with already existed packages. so i try deleting memu webview using adb shell, then install manually but still working , maybe system not detect new webview package that i install manually.

btw i already try updating whole MemuPlay with latest but i give up because its freezing crashing and lag pretty badly... maybe it too heavy for my PC.
anyone have suggestion?

Here you have the MEmu Play requirements https://www.memuplay.com/blog/system-requirements.html, although it's compatible with W7, probably you can update to a light version of W10 https://computerhoy.com/noticias/te...arlo-ventajas-tiene-frente-windows-10-1041257 actually I don't use it, so I can't sure you which the issue is, anyway, in the link you have the MEmu´s blog and forum from where you should find valuable information.

not really answer that i need. already using memu 7.6.6.0 and its already feel stable. i need to solve webview problem.....so that any in-game browser its not broken. because after updating aov, in-game browser is broken and only showing blank white page.
"i dont want to update whole memuplay" because its freeze, lag and feel heavy.
and updating whole windows to 10, its different matter again.....

Well, not always, the answer we have, is what we want, but still, they could be what we really need anyway, I never said that this is the panacea.

Only I can add to this, that you should check all the caches pertaining to the browser and the web view apps, also delete all the other web view you have installed, check in developer options that, the web view you choose is what is set by default (in case you have no root, and you can't delete the one that is in-built), also, if you want to use Chrome as web browser, better choose Chrome as web view app by default.
I try updating or changing manually using latest google webview and bromite webview but its say cant install because conflict with already existed packages. so i try deleting memu webview using adb shell, then install manually but still working , maybe system not detect new webview package that i install manually.
ADB shell doesn't delete, really, the package installed, so you can expect conflict, you should need root, to completely remove them.

How do I build Pixel Experience 12.1 for my device (Galaxy Tab 4 10.1; matisse)?
If you go to the Pixel Experience GITHub page, they will normally have instructions on how to build for official devices. Or you could simply search "how to build Pixel Experience". that should get you to the same page.

I dont know your device, but assuming its not am official device, then you need to find compatible Vendor, Device & Kernel sources for your device. A lot of custom ROMs will have instructions on how to create the ROM for unofficial devices as well. If your device has no 12.1 ROMs, then it will be hard slog, not for the inexperienced looking for a quick win.

My device doesn't have any Android 12/12L ROMs, neither does it have any Pixel Experience builds, not even unofficial.

i think i've seen this question before but a search didnot produce productive results.
in my email app , if i click a link it use to ask me which of my 3 browsers i wanted to use. now my email app just picks one automatically , always the same one.
anyone know how i can make it go back to asking me which to use?
(i cleared cache of all 3 as it was all i could think of to do).
thanks for any suggestions ,

Check that you don't have that browser set as default.

Clear defaults from the three browser apps, in case some of them have an option like opening tool chain in case you some time, granted this permission, probably this app will be open as most frequent used.

Apart from clear caches, if nothing of the other solve it, you may clear data from the email app.

Then you have a LOT of reading, and I hope you are a talented developer.

In my eyes, your biggest problem will be creating a device/vendor/kernel code for your device. (ie the device tree) I havent built for a few years, and I wish to keep my current phone on A11 but all ROMs have moved to A12L ; the problem with Pixel Phones. I went to check my preferred ROM's device tree (for my device) on GIT, and I found they only had a A12L tree. Normally you could see all the old/previous trees, but I also noticed that the A12L device tree hadn't been changed in a year. That makes me think I may be lucky and the current A12L tree is the same/compatible with A11. Which in your case may mean that an old A11 tree is compatible with A12L.

When I started building ROMs, it was a case of try, and then fix each specific actual issue as it came up. Without specific actual issues, its like asking the length of a piece of string. Try. Use one of the other devices as guide / starting point / learning path. And to be clear, if you dont have a prebuilt device tree source, it a lot of work. They problably have a telegram channel or such for extra ROM building help.

My device has a device tree for Lineage OS 18.1. Can I use that for building Pixel Experience 12L? Can I follow the build guide for an official device to build unofficial Pixel Experience 12L for my device?

a couple of problems there. Most ROMs are broken into two categories. LOS or ASOP based. I dont know Pixel Experience, but I would guess that its AOSP. The device trees are probably not compatible.

...smip...Can I follow the build guide for an official device to build unofficial Pixel Experience 12L for my device?
Not EVERY step is the same for unofficial. You will have to manually edit/create you device tree for the inclusion of your specific device. I previously had to modify my device make files, to make them compatible with the different ROMs i tried to build.

In short, if you have an unofficial device to build for, it is not a simple "follow these exact steps letter for letter". You are going to need to do some programming.

What's the easiest way to make an unofficial build of a ROM? Pixel Experience only have build guides for official devices. How do I create a new device tree for my device for Pixel Experience, or edit the current Lineage OS 16.0/17.1/18.1 device tree for my device to make it compatible with Pixel Experience 12L?

What is "easiest" is dependent on you.

I think I have already answered that question (more than once). Thats a bad indication, as to build ROMs, your going to need to do a LOT more reading, and take care to understand what you have read. There are many guides available on the internet, dont depend on some random guy on a forum to have all your answers. Search & read and teach yourself.

You should never install a non-tested ROM to your device. Now you have to try to install again the stock ROM, to see if this fix the issues, miss-flashing may cause. Search for the stock firmware for your device, and apply it using this https://motorola-global-portal.cust.../158726/~/download-rescue-and-smart-assistant

    ok , not sure if there is help for this but ; i got a used htc m9 thats att branded but had been used on metropcs. i cannot get a data connection. cannot change APNs. when opening apn screen there is a message , "apn settings unavailable for this user".
    i went ahead and used kingroot to gain root thinking that would allow me to modify apns in system (if thats where they are and if i could find them) but system is read only and so far cannot get rw permission. have tried with a root app and TE using "remount -o ………"
    anyone have an idea for me to get rw in system?
    p.s. tried "supersume" app to get superSU but fails every time so far.
    p.p.s. phone not recognized in computer. when plug it in no dialog pops up about allow this device always etc.
    any ideas , thoughts r most welcome ,
    dave
    Probably, you can modify those files and push them back using TWRP. Also, you have this https://forum.xda-developers.com/t/...-superrw-featuring-makerw-read-write.4247311/

    Hello,


    I am new to this forum and sorry to duplicate the question. I posted it in a separate (stand-alone) thread but have not received any responses.

    Basically, I just bought 2 prepaid TracFones, one is TCL A509DL (Android 11) and the other is LG Stylo 5 (Android 9). I was trying to make them my GPS units without activating them. One caveat, I have headaches from EMFs, so my thought was to put both phones in Airplane Mode and to use a USB to Ethernet dongle and connect them to the Internet over the wired connection to run initial updates and to update maps. None of the phones recognized the Ethernet connection.

    Is it possible to run initial updates using Ethernet with the stock drivers/firmware, how do I update to the latest? Or do I need to root the phone and find some alternatives to google maps?

    Would you please suggest?
    Thank you

    Airplane mode makes it ignore connections via internal radio and USB. You probably won't find a solution to work while airplane mode is enabled.

    Can we use samsung m21 rom in m30s since all specs are same except selfie camera ?​

    Probably, if the camera doesn't work, you might be able to extract the files to make it work from your stock firmware and apply them to your ROM.

    I'm sure there's a better place to ask this, so apologies. Is there only the one xda app available (on Google Play)? It seems incomplete, or just hard to use. I get a better experience in the mobile browser. Am I missing something?
    i think most peeps get better experience in mobile browser. i personally use the app though. but whichever suits best.

    Hello guys..:)
    I would like you to go through XDA new users guide and you must read the FORUM RULES before posting here or anywhere else on xda.

    The rate at which the new users are joining xda on daily basis is very high. A lot of users join because they have got some problems with their devices like bricked phone, bootloops etc. because of following incorrect processes. Some join to help out others, to share their knowledge and gain more.

    So basically this thread is for all of those who want to ask questions and answer those.


    So those who want to help here, just try to answer without flaming, let it be answered thousands of times earlier, show them the path, direction and let them do things on their own. Do not spoon feed, rather just try to point them to right direction.

    This whole idea is of @undercover and the former OP Bruce Wayne and I thank him.

    To The people asking questions here, don't forget to check for the links from 2nd post. That will help you increase your knowledge, and do answer the questions asked by others if you know the answer. Please don't simply say thanks if some member helps you, instead use the thanks button, that will help us keep this thread less cluttered.
