General :: Android Won't Boot - MNT Folder Missing?
Nov 24, 2013
I wanted to enable full gpu rendering on my Samsung P6200... I am running 4.1.2, rooted. I downloaded the zip file, booted into recovery and installed the zip file, I rebooted, it shows the normal model number and that on the screen, and about the time when the boot animation starts it just goes blank, although it is still on, now, I rebooted back to recovery, I had made a backup moments before, I only had 770 MB of space left so it made a full backup except my /data partition, that failed, but I didn't want that backed up anyway.
I thought well maybe I should restore, so I went to advanced restore and chose the boot partition to restore, restore was succesful, I restarted and did the same thing, now I try to restore the whole backup and it says md5 mismatch, I connect to adb and mount everything, and find my mnt folder is missing, now I don't know how to fix this, if I go to install zip from sdcard it shows all my files and folders there, but if I go to /sdcard/storage/sdcard0 in adb it only shows two folders, Download and Webzine. How to fix this, I don't want to restore my /data partition due to the fact that it only did like 5% of the backup of it and need a lot of that data, if I were to fix the md5 mismatch (don't know how) what partition would I restore to fix the boot error? And how do I fix the missing mnt folder issue?

I should start off by mentioning im completely new to rooting and custom ROM (or even UNIX for that matter).I've just flashed a CM 10.1 rom onto my LG Optimus 2x. In the process my phone has lost its IMEI, and for that reason i cannot connect to any mobile network.In the 'about phone' section of the settings, it shows IMEI as unknown and Baseband as unknown.
I've learned that this may have to do with a corrupted EFS folder/partition. I didn't make a backup of this folder (i were following didn't mention that i should have done that)Now I'm trying to follow along with this guide to recover my IMEI. URL>....The problem is i don't even find the /efs folder in both the terminal emulator or this app I've downloaded "ES File explorer". Does it mean its been deleted? I've read that it may need to be mounted so i found this command somewhere on XDA to use
The first line worked in the terminal emulator, but when i tried entering the second line i get an error 'mount: No such file or directory'.

I recently switched to Ubuntu and decided to use NetBeans for Java development instead of Eclipse which I used on Windows. The problem is, in the Eclipse I used on Windows, I had a folder named "drawable-hdpi" with the standard app icon in and a few other folders like "drawable-mdpi" (I think). But with NetBeans, there doesn't seem to be any folders named "drawable".

I am experiencing an annoying problem with an Android project in Eclipse. All my other Android projects are okey (at the moment). Whenever I perform a clean (Menu:Project->Clean...) the project gives an error and I can't compile/run the app. The error is: Project 'Project Name' is missing required source folder: 'gen'
As soon as I edit some code the problem disappears until I perform a clean again. I can also right-click on the gen-folder and delete it. Eclipse will recreate the gen-folder and the problem disappears until I perform a clean. This is not a showstopper but it is really annoying since I sometimes have to do a clean before I run the app.

Whenever I do a Clean on my project, I get 2 errors:
1.) The project is missing gen folder.
2.) There is a build path error.
I go to "Configure build path" and uncheck "Android 1.6". It works. If I do this again, I go and this time check "Android 1.6". It again works.

I downloaded the bootanimation.zip for the droid 2 and all instructions and tips say:
If your rooted it's as easy as putting it in the /data/local folder!
Well there is a /data folder on my Nexus and it's empty. If I try to make a new folder it says "cannot create new folder" in File Explorer that came with CM6.1. Astro greys out the create folder button. What am I missing? Also I saw that you can ADB push it. WTF does that mean? I know how to do some fastboot stuff, is it the same? Reboot the phone with the USB connected and run commands on my PC?

I try to understand android boot sequence on my JB (under CM10). I found some docs and there should be specific partitions (boot, recovery, system, cache, data).
My understanding of the boot sequence is now:
A) normal boot:
1) Power ON ->
2) bootloader ->
3) boot-partition where i flashed the kernel aka boot.img ->
4a) system-partition with the OS (libs, UI, etc) where i unpacked over CWM my customROM.zip ->
4b) data-partition, where i unpacked google-apps.zip and installed all the apps ->
4c) cache-partition with user data
B) recovery boot (adb reboot recovery):
1) Power ON ->
2) bootloader ->
3) recovery-partition with CWM where i may unpack all the .zip stuff to proper partitions, or restore from sdcard, etc.
Is this correct? I wonder, because i didn't installed CWM into recovery-partition. It cames from install of CM10 (fastboot -i 0xfce flash boot boot.img), so it must be in boot-partition and not in recovery?
So, next confusion: i looked up to /proc/mtd and i don't see neither boot nor recovery partition here:
Quote:
# cat /proc/mtd
dev: size erasesize name
mtd0: 19000000 00040000 "system"
mtd1: 00600000 00040000 "appslog"
mtd2: 06580000 00040000 "cache"
mtd3: 1a400000 00040000 "userdata"
I did a backup with CWM and loocked the data. There aren't boot, and recovery backups:
Quote:
# ls -lha /sdcard/clockworkmod/backup/2012-10-04.18.49.55/
d---rwxr-x 2 system sdcard_r 4.0K Oct 4 18:56 .
d---rwxr-x 3 system sdcard_r 4.0K Oct 4 18:49 ..
----rwxr-x 1 system sdcard_r 1.6K Oct 4 18:54 .android_secure.vfat.dup
----rwxr-x 1 system sdcard_r 54.6M Oct 4 18:55 cache.yaffs2.img
----rwxr-x 1 system sdcard_r 360.2M Oct 4 18:53 data.yaffs2.img
----rwxr-x 1 system sdcard_r 212 Oct 4 18:56 nandroid.md5
----rwxr-x 1 system sdcard_r 214.6M Oct 4 18:51 system.yaffs2.img
#
So, i think i didn't understand the boot sequence and partition schema corectly.

I am trying to do some low level performance testing related to device processor cores through adb which I feel it is affected by Android background services and system stuff.
As I know that the Android boot sequence stages are as follow:
1.Execute Boot ROM code.
2.Execute the boot loader.
3.Load the Linux kernel.
4.Launch Zygote, which initializes the Dalvik VM.
5.System server which loads the Android system.
So my question is how can I interrupt this sequence to force it stop on stage 3 to load Linux kernel. This can implement my intermediary performance testings before loading again Android system.
Does Fastboot or Clockworkmod recovery can load my device to a kind of Linux kernel?

Instead of seeing the boring old Android logo or my service provider's logo, I'd love to see the standard text-based Linux boot screen that shows the status of all the hardware and configuration info as my phone boots. My current phone is an HTC EVO 3D running Cool ICS with Sense 3.6 and Revolutionary CWM.

When I open my Instagram (using xperia ray latest Gingerbread stock ROM), and go to "Photo Maps", a dialog box appears saying "Photo Maps requires that the Google Maps Android API is installed on your device
I tried uninstalling and reinstalling both Google Maps and Instagram, I restarted my device too. But it doesnt solve the problem.
I tried checking /system/framework/com.google.android.maps.jar , I thought I lost this file but the file is there..
This is a rare problem and I only found 2 search results on Google about this problem, and both were found on XDA forum. One had his problem solved by placing this .jar file there. The other one tried placing the .jar file but no luck.
It's bothering me. Because I think it will affect other application that uses google maps. But I'm not sure. And I don't want to reinstall the whole ROM because I have partitioned my SD card, put many stuff in it, I dont want to start it all over just because of this small problem.

I just bought a 10.2" Flytouch 8 tablet with Android 4.0.4. In the Security menu I don't see any screen lock line to lock the screen; so I cannot lock the screen.
According to the online guides I consulted on the web it should be there. How I can access the screen lock menu?

I'm trying to add an application to the android source code in packages/apps. I have been following several tutorials and they all use the "mm" command to build their app they are adding. But I can't find the "mm" command in any of the android source code that I have downloaded and built.
-- mm: Builds all of the modules in the current directory.
Does mm have to be downloaded separately? When I build android source code, I get a folder containing lots of commands but mm is not there.

I am running pa_skyrocket-3.57-10JUN20130131650 and pa_gapps-full-4.2-20130719-signed on my ATT Samsung Galaxy SII Skyrocket.
I like the PIE features, but the status notifications don't show up if PIE gravity is set to anything besides the bottom. I get the "back", "home" and "multitask" buttons. When it is set on the bottom, I also get the time, battery info, date and any notifications. How to enable the missing status notifications when PIE gravity is set to anything besides the bottom?

I am trying to play a video in android emulator I have the video in my assets folder as well as the raw folder.But after doing some research still i cant play video in my emulator.i am working on android 2.1 My video format is mp4 so i don't think that should be a problem.Could anyone just give me an example code so that i can understand a bit more?The problem is that the VideoView that I need to display the Video will take only a URI or a File path to point to the Video.If I save the video in the raw or assets folder I can only get an input stream or a file descriptor and it seems nothing of that can be used to initialize the VideoView.

I'm running an SGS2 with CM9 (always up to the latest nightly).
I noticed today then when trying to open the Play store, it takes me directly to the Apps section and doesn't let me choose between the normal Apps, Movies and Books sections that i could before (i'm in the UK so no music option ever existed).
If i go to Play Book or Play Movies and press the market button, same happens, it just takes me to the apps secions.
I've tried clearing data on all google play related apps and uninstalling the google play updates and rebooting etc but still, everytime it takes me directly to the apps section and doesn't let me access any other section...

I followed the effen manual to flash a new ROM for my HCT Desire HD on Monday, December 12th with absolute success. However, I have lost the start up sound file and when I boot my android, it boots in quiet mode. I searched for a solution and found many threads explaining how to disable it, but very little on how to enable it.
The problem is when I open my SDcard and look in the media/audio/notifications all I have is a facebook.mp3 file, I do not have any other files that would allow for the start up sound to open on boot.

Is it possible to modify the folder grid width within android. For example, by default if I have 3 apps within a folder it will be displayed within the folder in a 2x2 grid with the top two spots and the bottom left occupied with an app. Instead I would like to modify it to be a 3x1 horizontal grid.

In the Phone Memory (not the external microSD) there is a folder named Android.
It has two folders in it, "data" and "obb".
Memory cardAndroidobb
Memory cardAndroiddata
Is this like "program files" in windows? Or "/usr" for freebsd or linux file folder structure?

How easy is it to make an application that's just a wrapper around the browser? Can the Android OS boot directly into that application so that only a certain application launches after boot. I'm building a client some custom software and I'd prefer to use one of those Archos 5 MIDs than a Linux netbook.
