Yes, it is possible to install custom kernels on stock roms. The kernel developer will usually say which roms (or types of roms) the kernel supports. If you are not sure you can try reading the kernel thread, and there will always be poeple saying things like "working great on [firmware version here]". This way you can also make sure that it will work ok on ...

Short answer That very much depends on your device, as the rooting process often is device specific. Following up to the rooting tag wiki will give you some basic info, and also provide a link to our rooting index, which might even already include a link for your device. TL;DR Basically, rooting just means to push a binary (su) and a helper app (SuperUser/...

Yes, you can check the SHA1 or MD5 checksum. You didn't specify which ROM you are downloading. Let's have a look at the Nexus stock ROMs: https://developers.google.com/android/nexus/images#mantaray There is a download link and a version number and checksums listed like that: Version: 4.2.2 (JDQ39) Link: https://dl.google.com/dl/android/aosp/mantaray-...

Factory images are bootloader compatible images, that is to say, they can be flashed using fastboot or alternative low-level tools or environment. Full OTA images are over-the-air updates that are to be flashed via recovery environment. OTA updates are usually either incremental or full. Incremental updates require the user to be running a specific Android ...

This is a protection that HTC uses to ensure quality in their devices. To re-install their custom stock, you must re-lock your phone. To do this, place your phone into fast-boot mode and plugin in via USB: At the command line (or wherever you may have the fastboot binary), execute these commands: fastboot devices fastboot oem lock This will lock ...

TheBro21's comment applies only if it's a KNOX enabled device. For most Android devices, when you boot into downloading mode it will read a few lines in "SYSTEM STATUS: custom" or "Custom Binary Download YES (and the number of time here, if it hasn't be reset with triangle away)". If in bootloader mode it says Unlock state: true, it might be that the ROM is ...

I am assuming your device is NOT rooted by you You can Factory reset your device (of course after taking back up of data ) Root your device, flash a custom recovery and take a complete back up of your device with TWRP Generate MD5 check sum using TWRP or alternate apps like Hash Stamp MD5 & SHA1 generator Download stock lollipop (assuming that your ...

In theory - yes. In practice, it varies from device to device - a very common way of an end-user obtaining root is to flash an insecure kernel. This can be a standalone kernel or a pre-rooted kernel + ROM combination. For certain devices, there are also available a number of 3rd party "one-click rooting" apps. That being said, rooting might cause your ...

1) Building in Android could mean: - building a deliverable in the android build tree - building a deliverable on an android platform having build tools installed - building the AOSP (Android OpenSource Project) A little bit more context may help. According to the following question 'the build system is different from other Linux systems' it could be the ...

After OTA system update, does the device install OS to both partitions? Or install to only one partition. and whether the device continues to same(current) android version until reboot manually?(after installing version update). Or whether it updates current to latest version overnight. It installs only to the inactive partition, which becomes active ...

You need to use a third-party launcher app like Nova Launcher. In Nova Launcher, you can hide the persistent search bar by navigating to : Go to Nova Settings > Desktop > Persistent Search Bar > Select "None".

The answer is YES . It is not mandatory for you to install custom ROM for rooting your device. ROOTING process is a actually YOU ARE GETTING ALL THE PRIVILEGES of your phone . So it is not necessary to install Custom ROM Steps to Do Rooting : Find root files for your Android Device on the internet(Every phone has a different root file ). Place it in your ...

There is no GT-N5200 or SM-N5200 produced by Samsung, and Samsung never produced MediaTek-based devices. Add the fact that the FCC ID is that of P1000 (Galaxy Tab 1st-gen), and it's obvious that your device is a fake copycat, and a poor example at that. Don't expect to find anything for it.

Searching the web gave me a clue: While before Android 7 one could easily flash a custom recovery without fearing side-effects, starting with Android 7 the system enforces DM Verity. That is, at a very early stage in the boot process, the system checks whether any partition was "tampered" with – which in my case meant the /recovery partition. As far as I ...

If it isn't the overlapping WiFi channels: a normal Nandroid does include /system and /data, but I think you can just flash them separately. What you're referring as "firmware" is probably the /system partition. If you guys are using the TWRP recovery, you should be able to add his entire TWRP-created recovery onto your device, boot into TWRP and start a ...

Based on the screenshot, you have the stock recovery. The stock recovery normally shows "Android System Recovery <3e>" whereas custom recoveries tend to have their name instead. There are two popular custom recoveries both of which look quite different to the one in your screenshot ClockworkMod: TWRP:

Most Samsung apps will not work on CyanogenMod because they are TouchWiz-based. CyanogenMod is AOSP-based. You would need to flash a stock ROM, or any custom ROM that is TouchWiz-based.

Well there are many advantages of using custom ROMs. Just removing bloatware from your phone doesn't make your stock ROM a custom ROM. Custom ROMs like their name, are based on "custom" code and are not based on the ROMs made by the manufacturer. There are many custom ROMs that change the base-band of your phone which in turn improves the overall signal ...

Old things tend to stick around. In everyday things (toasters, microwaves etc) there is some kind of software to control the device. That software is installed by the manufacturer and is usually hard to change, in practice read-only. While you can flash the system partition on android, with some electronic devices you needed to and still need to plug in some ...

If your phone's bootloader is locked then you definitely need to unlock it before performing those operations or non of them will succeed (the bootloader throws an error of some sort like "FAILED (remote: Command not allowed)" I ran this command on a phone with locked bootloader C:\AGUSTINO_ROOT\2014-08-02.21.07.25>fastboot flash recovery recovery.img ...

This is based entirely off @Firelord's comment, with some modifications, so all credits go to him. First things first, the stock ROM is not as such stored anywhere on device in a form which the device can use to recover itself in case of some catastrophic software failure, such as a botched OTA. Now, as to how stock ROMs are stored for distribution, that ...

Signed fastboot zips: These contain the complete rom and can overwrite everything including your data partition. These cannot be flashed via recovery - extract their contents and flash via fastboot.

The main difference is that the single file doesn't Factory Reset the phone after flashing, but the 4 file firmware does factory reset and remove absolutely everything and make it like an out of the box phone. The 4 files are called Binary Firmware which contains all the files in certain order: Bootloader contains all the boot files AP contains all the ...

My experience tells me that for TWRP to detect backup files the latter should be in a directory whose name would be shown as the name of the backup and that directory in turn should be under: /sdcard/TWRP/BACKUPS/<serial>/ Here, replace <serial> with the serial number of your device. You can find the serial number of your device using the ...

Well that took quite a bit of work. In the end I was able to get the custom firmware for the Hudl mentioned on the MoDaCo forum. After that the difficulty was getting the USB Drivers up and running to get the Hudl happy as an MTP device. I think this is how it went...

EDIT: This fix was temporary. The problem returned the next day. Sorry. After I flashed Cyanogenmod 12.1(upgraded to lollipop) to my nexus 5 I had the "no Sim Card". It is a very popular problem for this ROM or Lollipop in general. I try shimming the sim, Updating PRL etc... and nothing was working. Here is what I think finally fixed it for me: In dialer ...

Have you rebooted the device after "Unlocking bootloader"? fastboot reboot You need to execute this command before flashing custom ROM. Also, You don't need to turn on USB debugging when unlocking bootloader.

I'll just quote Elluel on XDA: Don't bother messing with reverting everything just to update, it is extremely unlikely to work since as of Lollipop Google has changed the OTA method to check the sum of the entire partition rather than only what it cares about. Download the 5.1 factory images, and flash system.img, boot.img, cache.img, radio....
