I wanted to create a thread in which any question can be asked, be it porting related or anything and we all help each other out, this has been going for a few years now and has been a huge success so I have updated the quick start guide and I will be a more ever-present force in the thread to answer any help and such that you may need, because if we all help each other this place can be a more user-friendly and more interactive place to visit.[/B]


Please also note you may PM me if you wish to ask anything in private, or if you feel the need to just say hello.


Please also note that this thread was indeed a sticky at one time however I had other commitments in 2011 (College and such) and it was removed by November 2011.


For donations, I would kindly ask you to donate to the Macmillan cancer care and support, however if you wish to donate to me I will donate it to the charity anyway, myself and Macmillan thank you for your support, no one should have to face cancer alone.



HERE IS A GUIDE TO GET STARTED



GENERAL KNOWLEDGEv1.0

S-OFF - (HTC Devices)[/B] Basically means you can flash ROM's to the SYSTEM partitions and such.

Write Protection - This can mean a variety of things, from a locked boot-loader to SD card access, consult your device forum for information.

Bricked(Soft) - Soft brick means that it can be recovered using appropriate methods found in your device forum.

Bricked(Hard) - Very hard to fix usually means it's beyond repair but can be fixed in certain circumstances and at a local repair dealer for your phone.

Kernels - The backbone of the phone, they are responsible for making everything run, the CPU, Schedulers and such are configurable using the kernel.

CPU0 - Different for each phone however CPU0 is usually the 1st logical processor followed by 1,2,3 for quad core phones.

Dual Core/Quad Core - Dual core means you get CPU0 and CPU1, Quad core means CPU0, CPU1, CPU2 and CPU3 are all available.

Chip-set - This is your main-board, it means what your phone is built upon.

Lib files - Found in /system/lib usually however this can be different, they control the software to firmware gaps on your phone, so they enable sound, camera, video; the major things live here, don't touch it unless you know what you're doing.

Battery Stats - These control how long your battery lasts, they are reset when you delete the file from the system however it's strongly recommended you don't delete them.

AOSP - Basically means the original Google Android software as a bare-bone OS.

Partitions - These are different for each phone and should be treated with great care for example flashing a puppy to the radio partition would be a foolish action.

Launchers - They change the UI of the phone, there are many out there so try them all until you find one that suits you just right.

Logcat - This is only useful if you have an error with your phone, it's a simple adb logcat command however I prefer to use QTADB which is a nice GUI style logct application.

ROM's - You flash these on phones that are able to flash Custom software, you can get many varieties however the main ones are 'Stock' the original phone OS, 'CM' which is AOSP, 'MIUI' An AOSP/AOKP style crossover mimics the iOS UI.

Recovery - When flashed; custom recovery allows you to make changes to the different partitions inside the phone for example flashing a custom ROM.

Flashing - Basically writing information to a partition or making a fool of yourself in public (the latter is not recommended due to laws)

Over-clocking - This means pushing your hardware beyond its manufacturers original settings, this can be useful to create a faster phone but treat it with care as you can damage phone hardware.

Under-clocking - This means lowering the stress on the system by making the hardware run slower than it's intended to do, great for saving battery.

Under-volting - This means under-volting your CPU or GPU, this can cause stability issues but on the plus side can save battery, it's all about striking a balance.

Benchmarking - This means to test your phone to its max and find out how it stacks up against other devices.

IO Schedulers- They control how the system reacts in different situations, there are different types of Schedulers available so use each until you find one suitable for you (protip: Use fiops or noop)

CPU Governors - They control the CPU frequencies and such for example "Performance governor" will give you constant speed, whereas "Conservative governor" will give you low speed.

GPU Governors - They do the same as their CPU counterparts except they control the graphical section of the hardware.
Ii
Radios - They control the baseband aspects of a phone (your network and such) they have different names for each device, they are very dangerous to mess around with.

Galaxy Note 4 rom issue SM-N910F
Hey all,

I recently broke my main phone whilst carrying out a repair (Sidenote dont do repairs when your hungover)~

Anyway went back to using my note 4 and I couldent use my banking app because I had obviously at some point in the past rooted the phone.

So I embarked on a mission to unroot it which I was successful in.

But then I found a way I could have my phone rooted and use my banking app but it involved flashing the phone back to the stock rom entirely
I downloaded what I was sure was the stock rom for my phone and got to work with odin.

anyway the phone booted fine but whenever it tried to connect to the mobile network it rebooted itself.
Obviously not the stock rom

Ive since searched high and low for the stock rom flashed several on too the phone and yeah no joy
So right now I dont have a phone and im genuinly surprised at the impact that is having on my life lol.

So im hoping to get some help too find the stock rom for my phone

As says in the title its a samsung galaxy note 4 SM-N910F it was purchased in the united kingdom and the network is o2

Any help and advice would genuinly be apreciated.

Cheers.

I could use a bit of guidance in a direction...
Hello,

I buy a cell phone about once every 3-4 years. I like them to be last season's model so the price isn't too high, and most of all, I like to unlock and root them. This has become increasingly more difficult as the more time goes along there are less and less Verizon phones out there that I can root. Did I mention Verizon is the only network I can get coverage in my area? I actually use Page Plus.

Finally, my question:

I am in need of a new (new to me) phone for use on the Verizon network that I can unlock or root and make it do what I want. I have heard about the new kinds of rooting whereby you don't have to unlock the bootloader, but unfortunately I don't get involved in the process but as the aforementioned 3-4 year period. I am wondering if you could steer me towards any good Verizon prospects that can be readily rooted? I would appreciate it very much. A thousand thank you's in advance.

sdcard folder set not appearing in TWRP
I have just tried all day to root my phone (a Redmi Note 5), and have found myself stuck at the part where I'm supposed to either enter a password to decrypt TWRP (I already tried setting one for my phone itself, and TWRP doesn't recognize it) or try to access the folders that are supposed to appear under sdcard.

From what I gather, the following folders are supposed to appear under sdcard when I tap "Cancel" on the password screen and then "Install", and do appear under Internal storage memory when I hook my phone up to my computer:

-Alarms
-Android
-DCIM
-Download
-MIUI
-Movies
-Music
-Notifications
-Pictures
-Podcasts
-Ringtones

None of those appear for me under that folder, or any others within Internal storage.

Under internal storage also includes these folders, which I cannot access through my computer, and thus can't transfer files to:

-acct
-cache
-config
-cust
-data
-dev
-etc
-external_sd
-firmware
-license

Is there a way to recover the folders that are supposed to appear under sdcard?

Hi guys

I have a huge problem. I have a phone that the bootloader is in-eledgible to be unlocked. I would really like to be able to root my phone so my idea was to manually or programatically root it by some means.

Using termux i was once able to add my su binary to the /system/xbin directory but i cant remember how i was able to so. And yes i was unrooted at the time.

There has got to be some exploit i can use to deliver and modify the files. Can someone please help me

Hello,
I have Xiaomi redmi note 4 mido. Recently I was trying my luck with some custom ROMs (specifically aosp extended) which I succeeded but due to some problems while flashing I tried to update my twrp version from adb sideload, since I couldn't see any zip files in it. And now I can't boot into twrp, it says "system has been destroyed". I've tried reverting to stock rom and recovery then flashed twrp again but I still get the same error (stock recovery works just fine). Bootloader is unlocked and I can boot into bootloader, also phone works without any problem on stock rom(global version). Couldn't find any answers on web, other than how to get back to stock rom which is not my concern.
Any help is appreciated
