ROM Dumping, I am lost

Hello,

Trying to make a custom rom for a device i just got (it has no specific brand).

Tried dumping with romdump but boot.img was empty, so i had a look around and finally queried mtd:

cat proc/mtd
dev: size erasesize name
mtd0: 00040000 00040000 "misc"
mtd1: 00500000 00040000 "recovery"
mtd2: 00500000 00040000 "kernel"
mtd3: 00300000 00040000 "ramdisk"
mtd4: 0aa00000 00040000 "system"
mtd5: 04000000 00040000 "cache"
mtd6: 10800000 00040000 "userdata"

In all exemples i saw there was an entry with the name 'boot' and neither 'kernel' nor 'ramdisk'.

dd if=/dev/mtd/mtd2

and

dd if=/dev/mtd/mtd3

are not recognized as valid by the kitchen.

I am guessing that somehow if i managed to merge kernel and ramdisk i would probably get a proper boot.img but my (maybe wrong) thoughts stop right here.

Has anyone seen such a case before?

thanks

[Q] New to flashing - Basic questins

This forum is really big and I am new. I apologize if I am asking this in the wrong place. I have been reading a lot about how android working, and serving Google for answers.

I always thought that the only way to hard brick a device was to erase or corrupted the bootloader. Since even if the ROM and recovery had problems, you could use fastboot mode to fix things.

Now I am reading that Roms ussualy include a kernal, and flashing a kernal can lead to a hard brick. Does this apply to the Nexus 7 2012, or just devices that use download mode/ODIN instead of fastboot?

I always thought of a boot loader like an i intersection where you normally keep driving strait (into the main rom), or turn left (into recovery), or stay at the intersection (fastboot). How does a kernal tie into this? Do all Roms include their own kernal, or are different kernals and Roms usually flashed sepretly?

Thank you for helping me to understand this better.

I think the best explanation of what a kernel is, can be found here: http://www.androidcentral.com/android-z-what-kernel

In order to flash custom roms you absolutely must have a custom recovery. Can't do it any other way.

A custom recovery allows you to make complete backups of your phone and flash custom roms and other stuff. It does a lot of things, but these are the 2 main features that concern you. Here's a link to some info: http://freedupthoughts.com/2013/04/what-is-custom-recovery-why-should-i.html

[General Questions and Answers] MaHo_66:
Any android device who is capable of flashing custom roms or custom kernels whether in downloadmode/fastboot/custom recovery etc. could get bricked, you just have to be careful not to flash/install different kernels other then what is made specifically for your device hardware.

In official stock firmwares/ROMs who are flashable via fastboot or ODIN mode, the kernel is included already in the ROM alongside with the recovery, bootloader, system partitions etc.

In custom ROMs, the kernels are also included within the rom but these are modified kernels to let it work properly with the devices OS and are more often tweaked for performance, and thats why its called custom kernel. if your phone is capable of root and handling a custom recovery such as CWM/PHILZ/TWRP you get the option to choose whether you want to flash another kernel if there is one available of course, otherwise you could stick with the one that comes already with official firmware or custom ROM.

for your question about ''how does a kernel tie into the bootloader'' read further here

i hope this cleares out some basic things for ya :)

Yes bro, could be an exhausted battery.. But that shouldn't be a problem if you're getting good backup.

Its normal after a while for the initial cells to lose charge as they are the most used ones.

Try caliberating your battery by draining it completely (0 percent) and then charging. Do this a couple times, should help.

---------- Post added at 06:27 PM ---------- Previous post was at 05:49 PM ----------

your problem lies within the way you have installed the rom OR the settings you have applied for the rom. seems like your apps and or the device itself cant read the internal or external sd card (wherever you placed your songs) and thats why you cant apply them as your ringtone. try changing some settings related to the problem or reflash the rom with full wipe and dont mess with any mods in aroma installer, try default settings in aroma installer see if problem persists..

Photon Q Unlock Issues & motherboard question

Hello!

I've been following an XDA forum on how to mod my Photon Q, however I have run into a few issues and have been unable to receive help from those members at this point in time. I've followed all the instructions from the link provided in the forum (can't post here due to 10 post rule)

And have been trying to receive the unlock code from the Motorola site,

However, every time I type in the OEM code I've received off the phone, it states the device is unlockable...which is incorrect. SO! Is there anyone who can direct me in how to extract the OEM code off the Command Prompt Window and correctly insert it into the Motorola website? As the issue is simply that I've somewhere mistyped this 99 digit code.

hi i have an lg optimus f3 and a long time ago i switched the internal sd card with the external one for use of primary storage. any games i had or any apps would be installed to the external memory but the phone would see it as the internal. for example normally internal storage would read 1 gig and external would read 16. but with that external 2 internal app it would read internal 16 external 1 gig. with that in mind i have done it before but me and my dumb self flashed my phone to get a fresh install for some new modding. however i forgot to save the settings for that and now i cant make it work again. can someone help me please? i just want my phone to use my external sd card for everything instead of my internal one. i dont care if i have to edit files or use an app. but just some clear step by step advice on how to do this. i did it before but it seems as if its being stubborn this time around. thanks in advance.
