A "Recovery" is a special space in the internal memory of your phone, set aside by the manufacturer to perform diagnostics and OS upgrades. In Windows terms, it's a rough equivalent of Boot Menu (usually accessed by pressing F8 during boot-up.) It's invisible to the phone under normal operation, and is accessed in a special way (usually by turning the ...

It sounds like the "/system/bin/app_process" has been modified and so it doesn't match the signature required. There are 2 ways to fix this, either get a copy of the stock file from another phone/rom or flash the factory image for 4.3 Edit: After reading "update 2" it sounds like you want the factory image option detailed below. AndroidPolice has a step by ...

ClockworkMod Recovery is a "custom recovery image" which is installable on many Android devices. You can install it in order to replace your device's "stock recovery image" with something more useful. Specifically, it can be used to backup and restore your current ROM and data, as well as to install new ROMs. You can use ROM Manager to manage which ...

No, it does not format the SD card. It only wipes all internal memory on the phone. It is recommended you do this every time you switch to a new CustomRom, or if the current CustomRom is giving you problems (typically after upgrading the CustomRom).

In short, if you want to flash KitKat Android 4.4, you'll have to upgrade to a version of CWM greater than v6.0.4.5. Or, use an alternate bootloader. For the Galaxy Tab 2 GT-P5113 or GT-p5110 you can find the instructions here.

I had the same problem and I found the solution is to rename a file in the system folder: remount /system in read/write mode (use something like the Root Explorer app or ES File Explorer; both have root modes (check the app's settings) for remounting /system as writable) rename the /system/recovery-from-boot.p to /system/recovery-from-boot.p-bak ...

If you have a fastboot-enabled bootloader version (such as the old 0.76.0000 engineering HBOOT in the EVO's case) you can use that to flash it from a PC via USB. Reboot into your bootloader, then select the "Fastboot" option from the boot menu (if it has one, it may start up fastboot automatically). Once it's ready, go to your PC's shell and execute: ...

Starting with version 6, deduplication support has been built into clockworkmod recovery. The blobs directory folder contains a hashed directory structure that holds the deduplicated files across all backups. See the developer's Google+ post for more, in short: TL;DR: ClockworkMod Recovery now deduplicates files between builds. This results in way ...

First, some disambiguation is in order. Amon_Ra is a developer who created one of the recovery consoles (named after himself.) Just like ClockworkMod (which was created by a different developer named Koushik Dutta, a.k.a. Koush) Amon_Ra's Recovery performs various low-level tasks on Android devices. Odin is a Windows application that can be used to flash ...

Two things are important here: 1.) Even if you wouldn't install ClockworkMod, you'd lose your warranty since you replaced the pre-loaded operating system with unsupported one. 2.) ClockworkMod (or any other alternative recovery) is what actually installs CyanogenMod on your phone so it is required. In short: Replacing your phone OS with Cyanogen will void ...

The required part of a kernel .zip file looks like this: META-INF com google android update-binary updater-script You'll also want to have the kernel zImage file somewhere else, easiest if you just have it in the root of the archive. updater-script contains the following at minimum (assumes zImage ...

Clockworkmod stores its backups in /sdcard/clockworkmod/backup (replace /sdcard with the path for your external card if you're looking for backups to external memory). With versions prior to 6.0, you can move off (or delete) the entire directory to clear space. The entire backup is self-contained. If you're using a 6.0 or greater version of Clockworkmod, ...

It does this in order to break up large .tar files into chunks of 1000000000 bytes (or 1 GB): -rwxrwx--- root sdcard_r 0 2014-03-19 14:31 data.ext4.tar -rwxrwx--- root sdcard_r 1000000000 2014-03-19 14:33 data.ext4.tar.a -rwxrwx--- root sdcard_r 1000000000 2014-03-19 14:36 data.ext4.tar.b -rwxrwx--- root sdcard_r 1000000000 ...

I would check your /sdcard/clockworkmod/backup folder and remove any old backups you have in there. You can also remove them from within Rom Manager under Manage and Restore Backups. Then click on the older backups and select Delete from the menu.

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 ...

Primary reasons for the no swap recommendations are the basic uselessness of swap for most devices, performance reasons, and device longevity. As Liam mentions, modern devices have no shortage of RAM (Even my old underpowered Wildfire S has as much RAM as my previous desktop.) and that RAM is managed fairly well by the modern Android system, making a swap ...

I just a got an email from the Heimdall dev, he said it's not compatible with the Galaxy Mini. Thanks guys for your replies.

The easiest way would be to install Rom Manager. The first item in this app says "Flash ClockworkMod Recovery" and under that it will say something like "Current Recovery: ClockworkMod 5.0.2.2" (see below). If it does not say this, or has nothing here, chances are you don't have it. If you don't have it and would like it (and are already rooted, of course) ...

To unpack a YAFFS2 image, you can use the free unyaffs tool, which is available as pre-build ELF-binary (for Linux) from this page at code.google.com. This page also contains hints on how to obtain the source code, so you could build the binary yourself e.g. with gcc (gcc -o unyaffs unyaffs.c). I use this tool myself, it works fine on Ubuntu 8.04 32bit as ...

CWM is the shortform of ClockWorkMod. ROMManager, CWM recovery, Tether etc are their products. CWM Recovery and ROMManager are tools which enables you to backup your current ROM, install custom ROMs etc. If you are interested in knowing more about CWM, see this page. For rooting you do not need CWM. In fact for installing CWM you need to be rooted. ...

It was removed because It's total placebo these days. I wrote it for dealing with the silly things that happen when we used to put apps on SD before Android supported it. Since then, it's been something of a sugar pill that magically fixes all problems without actually doing anything. (Taken from the commit history, posted by Steve Kondik)

A nandroid is the name for a complete backup or image of your device. It can be performed in clock work mod (cmw) . Clockwork mod is a custom recovery because it is a second of tools that can used without booting an os. Think of it has an additional BIOS. When rooting and jailbreaking, u will want to install the clockwork mod. It is the workhorse that has ...

One way is to open ROM Manager and choose "Flash ClockworkMod Recovery". Select your device when it prompts and wait for it to download the latest (non-touch) recovery. Using a file browser, go to /sdcard/clockworkmod/download/<site>/recoveries and paste your .img there. <site> may be mirror.kanged.net or something else, just check the folders ...

The easiest way to find out if your Galaxy S2 already has ClockworkMod Recovery installed is to try and boot into it. Turn off the phone, then hold the Volume Up, Volume Down and Power buttons at the same time. (For international version of the GS2 you need to press and hold Vol Up + Home + Power combination.) If it boots into ClockworkMod - you have it ...

I had the same problem. Looking at the source of heimdal revealed that this message is send when no USB device is attached. And this was in fact the case. lsusb showed that the kernel is not aware of any USB device related to the Galaxy S: flo@flo-pc ~/data/cm9-sgs $ lsusb Bus 002 Device 004: ID 046d:0990 Logitech, Inc.

If you are talking about a Nandroid backup: Yes, it would. It creates images from the devices file systems -- so all that's stored there gets copied to those image files. You can then even extract single items using e.g. Titanium Backup.

The general consensus is there's usually different partitions available: system data cache boot recovery When a guide says to flash "partition" where partition is one of the above, then that implies transferring the contents destined for the partition. The mileage will vary depending on the handset/manufacturer as not all of them actually have ...

Recalibrating your battery won't actually make it last longer. What it might do is ensure that the battery level display is more accurate, so that when it says it's at zero, it's actually at zero. Personally, I used an app like Battery Calibration (requires root) and it seems to help. To be fair though, I haven't actually tested the actual levels myself, so ...

This suggestion assumes familiarity with connecting to the phone via ADB I had a similar situation on my previous phone. I was able to pull the important stuff over ADB when the phone was in recovery. In my case I had to mount some of the filesystems to access everything I wanted to retrieve. I'm not sure if it is dependent on the phone whether the ADB ...

Sony Xperia Devices use a recovery-in-boot arrangement. While you can't simply flash a version of TWRP or CWM, you can flash a kernel that includes what you need. For the Xperia L, you can flash the Phanton Kernel, which includes CWM. There is no other way to do get CWM or TWRP without flashing a new kernel.
