I know its something fairly simple, but for the newbies out there, here's a simple walkthrough I made for how to flash a custom ROM on your Android phone. If there are any improvements I can make, let me know How to Flash a Custom ROM on Android
Benefits of Flashing a Custom ROM
While you’ll end up seeing a lot of benefits from custom ROMs, they all probably fall under 3 main areas:
Better Performance – You’ll be able to overclock Android or even see it built in with the ROM as well as see overall performance increases from various tweaks
Better Battery Life – One of the first things people do when rooting is remove stock apps. Don’t know how? Most developers have the apps already removed in their ROMs. Additionally, various system tweaks and improved kernels, as well as undervolting Android help to drastically improve Android battery life.
Better Overall Experience – Try other versions of Android such as those found on other phones that have been ported to yours; stay up to date with updates and new features; try out different Android themes, etc.
All in all, there are a LOT of benefits you’ll get from using a custom ROM on Android, so wait no more, here’s How to Flash a Custom ROM on Android.
Basic Steps
Choose the ROM that you want and download its .zip file
Transfer the zip file to your phone's sd card. Do not put it into any folder.
Turn off your phone and reboot into recovery, usually by holding the down button and power button at the same time.
Do a Nandroid backup
Wipe the phone by clear cache/factory restore and wiping dalvik cache
Flash the zip file that you put on your sd card
Reboot phone

Ohh I gotcha Well thanks man
how do you:
Wipe the phone by clear cache/factory restore and wiping dalvik cache
how do you wipe dalvik cache?
Also...
I downloaded Azrael v2.41
am I suppose to rename the .zip file from Azrael_v2.41_by_Ricsim78 to PC36IMG.zip?
I once renamed it to PC36IMG.zip and it would not read it and ask me to flash..

If you're rooted, I recommend flashing to Amon Ra Recovery.
When you boot into Recovery, go into the Wipe section, there are options there to "wipe factory restore" and "wipe dalvik cache"
After you do that, go back to the main screen in Recovery mode and find where it says "flash from zip file" (or something along those lines), then navigate to where you have the Azrael zip file.
I was in the same boat you're in, just 2 days ago. I've been reading these forums nonstop for 2 days now
I did the wipe..but I'm not exactly sure how to "flash from zip"
can't find that...
and still wondering if I have to rename anything

You don't have to rename anything.
What recovery are you using - Amon Ra or Clockwork
- If you wiped and performed a NANDROID backup, then select the option of "FLASH ZIP FROM SD CARD". Then you should see the .zip file of the ROM you downloaded, select that, confirm, and once done reboot.
Good to go!
there's so many guides..some are outdated and such
I don't have root access. Still trying to get to that part before flashing.
Already performed a wiped. Now I'm stuck and don't know how to perform a proper root since all the pc36img are outdated.
I have hboot 0.97.0000
dumb question but... after i flash from zip when do i then restore the nandroid??

After you flash a ROM, you don't need to restore the nandroid. The Nandroid back up is an image of your system at the time you do the back up. You would only restore the Nandroid when you want to go back to the version on the backup.
What I do with a ROM is load it, then get everything working the way I want it to and then do a back up of it. Can then go back to it whenever you want to after trying out more ROM's.

Hello, it's me again with new set of questions
My device is GT-I9001
1) What is Nandroid backup? Is it complete system image backup like Acronis True Image, created with CWM, because i have CWM installed?
2) I am planning to install CM9 on my device, is it possible to restore my apps completely with settings, and games completely with passed levels with Titanium (I've got Pro version). I need to know if any problem could arise when restoring? I also read not to restore system apps, my question is why?
3) Am I installing CM9 via odin or via cwm? I saw two files gapps and cm9, which is firstly installed?
4) How to wipe before installing custom ROM?
5) Could you find me Stock ROM for my phone, I've got no luck finding it? Here is PDA and CSC

1. yes, it is complete system image backup (can be created using CWM)
2. yes, you can restore apps including their settings via titanium backup.
3. please read the installation guide for your device.
4. wiping can be done via CWM
5. find it on your device sub-forum.
1) Ok, I understand...
2) There is still more questions I asked...
3) I cannot ask there until 10 posts, and it's a bit unclear/confusing to me...
4) I know that, what I need to wipe. I figured it's system, cache and dalvik...
Is it needed to go into mounts and storage and to format system, data and cache...
Is sdcard and emmc needed to be wiped?
5) I already said I cannot find it...
Anyone knows the answers?

2) if you just restore User-Apps you can not do anything wrong. Only if you restore Systemapps that are not for your new system.
If this happens you can easily restore your nandroid and start over again
3) Odin is more or less only for Stock Roms. CM is flashed through CWM
4) nope! If you do the Wipe, system, data etc. will be formated
5) you can easily find stock roms for almost every samsung device on sammobile.com
Thanks for clarifying
I searched every possible site, but still can't find my stock firmware
Hi everyone!
I have three questions.
1. a) The installation instruction on slimroms.net says you should do system partition wipe as well in addition to normal TWRP wipe. I used to do normal TWRP wipe only when I flashed SlimBean, and it worked (maybe not since it got bricked). Wiping system is actually necessary?
b) When you update the ROM, do you have to do full wipe again? Or can I just flash the ROM zip file after erasing cache/dalvik? I have long been curious about this since the first instruction always has this phrase: 'if you are coming from a different ROM'.
2. Is there a simpler way than using TitaniumBackup after flashing?
3. Do I need to flash updateSU zip file every time I flash the ROM?
Thank you in advance!

1.a. In TWRP > Wipe menu > You have an option to wipe the system partition so you just have to check it. Before doing this make sure that the option -rm is checked in TWRP settings.
1.b. Only wipe cache and dalvik cache for an update.
2. TB is one of the best apps to restore apps & data. You can also create a flashable zip to restore your backup.
3. Yes as long as SuperSU isn't fully implemented in the rom.

Another question:
I flashed franco on SlimKat ROM. So, do I need to do full wipe when I update the ROM?
Or can I erase cache/dalvik > flash ROM > gapps > franco > SuperSU?

No. Wipe cache and dalvik is enough for an update so "cache/dalvik > flash ROM > gapps > franco > SuperSU" is correct.
I'm not sure for SlimKat but with some ROMs you don't need to flash GApps at each update.

That's good. I don't know why formatting cache takes so long with Nexus 5. I'm always stuck at "Formatting Cache using make_ext4fs function" for a minute or two. This didn't happen with my Galaxy Nexus.

Sorry for bothering you with similar questions, but I just wanted to make sure! When I change the kernel from franco to Trinity, I erase cache/dalvik and just flash Trinity, right? Only when I want to try out another ROM, I need to full wipe? Thanks.

If you didn't modify the rom=> you can flash a custom kernel WITHOUT any wipe
If you already change the kernel => you have to dirty flash your current rom (no wipe) then flash another custom kernel
If you want to try another rom => you have to full wipe: data+cache+dalvik+system
hi,
i did a big mistake. I wanted to install some vpn apps, which requires write permission on /system. I downloaded root explorer und tried to set all permissions for the system folder. But the app stills lacks the wanted permissions, so i started root explorer again and additionally checked the checkboxes under "special permissions". After doing that android crashed, the "systemui" process crashed and restarted and crashed ...
I rebootet the device, but i only see "google" and then comes a reboot and the device boots into recovery (TWRP 2.6.3.4). I already tried the "fix permissions" under advanced, but it didn't helped.
Is there any way to fix whatever i did wrong and not lose any data?
Any help would be greatly appreciated

Thanks for your help. I don't want to miss something this time and complety brick my device. Could you/anybody tell me exactly what and how do flash to recover my device?
I did all the rooting stuff with the "Nexus Root Toolkit" program and followed strictly guides, except this time
Do i have to flash the rom with ADB? which file(s) should i flash system.img only? Or i have to flash more files?
A short noob guide would be really appreciated :good:
Greetings k1x1987
So you are just rooted on the stock setup? Then you should be able to flash a stock odexed rom that matches your current set up (4.4.1 or 4.4.2) and you should wipe, but just the caches. You'll likely need to adb push rom.zip /sdcard when in recovery. You probably could adb sideload as well, but not sure if that wipes anything else. Never had to mess with sideloading.
For future reference, once you are up and running, I think what you would need to change is the SELinux permissive state. There's an app do that. Then the most you would need is to hit the R/W button when you're in /system with Root Explorer. Or with the newer Root Explorer versions, once you try and make a change that needs R/W permissions, it'll stop and ask you if you want RE to switch it for you to complete the task.

Thanks for your help. Yes, i am complety stock besides root and franco kernel. I already downloaded factory image (4.4.2). Should i flash the zip, which contains all the system.img, userdata.img etc. (i think it was 5 files) or just specific ones? It would be n1 if my data dont get lost.
Thanks in advance.

Just flash the system.img in fastboot.
Most devs recommend wiping /system first.
fastboot erase system
fastboot flash system system.img
I would also erase cache too.
fastboot erase cache
That will clear the cache, not the dalvik, but think that should be enough to get going.
...and once it is fixed, never change system permissions again.... Same a Linux, never change permissions at /root
.. phone works again
thanks at all for the help. But now i cant get any cell service. I looked under settings/about the phone/status and saw that my "IMEI" is "unkown". Could this be the problem? I read about restoring imei, should i try this and it this the cause for me not getting any service?

Using fastboot, flash the cache image from the factory image, fastboot flash cache cache.img
^ That should do the trick. If not, well, let's not go there yet. The cache should fix it. If that does, do yourself a favor and back up your EFS folder and save it somewhere safe. Either use TWRP or flash the EFS backup tool from here: http://forum.xda-developers.com/showthread.php?t=2514095
Can i install roms on System 1, who and how? pls help, i dont want to break my phone, i 've LiquidSmooth but on System 3, i need more space and the only way its installing on system 1..
Who other roms can i install on system 1, and who are requirement? thx for your help :good::cyclops:
Yes, you can. In fact, I am using just System 1 (AOSB) as my daily ROM.
I don't know if this is required, but I'm always doing the following:
1. Format /system, /data, /cache
2. Wipe System, Cache, Dalvik Cache
3. Install ROM
4. Install GApps
I never had any problems since.
Goodluck mate!
Cheers,
Rae
I have never used any other system other than system 1 as daily driver..i don't know y ppl are so scared to flash..same time two years back we didn't even have a recovery on boot and still used to flash roms courtesy rdavisct, alteredlikeness, jimbridgman n co..this whole concept of multiple systems has made things more complicated than before it seems

Sorry to hear that.
So, are you saying that after you installed a ROM in System 1, you force-installed BMM again through System Keeper?
I think you need to FXZ back to stock ICS, then root, then install BMM from the market again.
I think I had the same experience back when I first got this phone and was still experimenting on stuffs.
Anyways, do you know how to FXZ back to stock ICS? There's a guide on how to do that here:

Dude you can flash ROM's on System 1 but please be careful as it will delete all other data on the other systems.
One more thing if your using altreds CM 11 use the BaNkS minimal gapps, It's not a problem to flash on the system 1, the thing is a failed flash can sometimes lead to you needing a FXZ, so just be careful on which ROM your flashing. :good:
I have little bit confusion. Please guide if these steps are correct:
1. Using BMM, format system 1 partition, data, cache.
2. Clean/wipe data, cache, battery, dalvik
3. Install ROM and GAPPs in system 1
4. system keeper > keep/install BMM
Are these steps correct?
Another question is if I want to install only one ROM in system 1 and want to use all available space for this setup then how to setup the partitions with maximum available space? Or I don't need to setup partitions?

No need to set partition sizes on system 1, that's solely for multi-booting ROMs on systems 3-6. Everything else is good though.

But one confusion, I use BMM for flashing ROMs. And in case of BMM, we have to set partitions for system, data and cache. How to do that partitioning step in case if we want to flash ROM in the system 1 ? Won't we have to specify the sizes for all of those partitions?
Another question is, how to fully clean up the system 1 and free up whole ROM space before starting system 1 setup? I mean can I clean everything which came from factory before flashing on the system one to get as big as possible size of internal ROM for the system 1 setup? How much space we can get by doing that? Right now it shows around 2 GB available for user (apps and data) in the 4GB ROM of the Atrix 2, how much would it show in case of custom ROM flashing by freeing up whole space?

System 1 gets partitioned by flashing the FXZ so it's not necessary to do it with BMM. The best way to clean up system for flashing is to flash the FXZ first, then root and install BMM, etc. You can also use BMM to format system, data, cache and dalvik cache if you haven't created partitions for other systems. The only reason you will ever need to create partitions with BMM is to flash on systems 3-6.

Oh, I thought BMM will do it on sys 1 as well. I used sys 3 & 4 just to try out various ROMs without risking the stock system so that I can know which ROM suites me and later I can cleanup the whole system and put that ROM of my liking in the main system.
I am not familiar with FXZ method and it seems more complicated to me. isn't there any way to flash ROM on sys 1 and deleting the other partitions?
I am noob in this flashing thing and its been just 10-12 days since I started it up. the bmm method looked easy to me and I would prefer it if its possible to use for this purpose.

Flashing the FXZ is actually pretty simple. The main thing to know is which FXZ is the correct one for your phone. (Also it's a really good idea to find THAT out BEFORE you need it.) BMM is far more complicated and confusing IMHO.
Anyway, it's still possible to do a clean flash via BMM if that's what you're more comfortable with, though, so no worries. Just do a factory reset, which will format data, cache, and dalvik. Since that formats the data partition you will lose everything on any other existing systems. (though it may not always be necessary I normally format the system as well. DO NOT reboot at this point or you'll have no choice but to FXZ.) Then you just flash the zip plus gapps and whatever other mods you want. Personally I like to reboot between flashing each zip. In other words, I flash the ROM then reboot. Then gapps and reboot, etc. No repartitioning is necessary for flashing on system 1 and might actually be detrimental so just skip that.
Thanks a lot @1BadWolf, your post clears all doubts in my mind

Thanks for letting me know about no need of partitioning sys 1. If I wouldn't have been in this discussion with you, I would have ended up creating partitions on system 1 as well like what I have learnt to do on other systems and there would have been a thread by me on getting stuck in bootloop, you saved me from that.
To be bit on more safer side, let me put what I have understood so far:
1. Boot in BMM.
2. Factory reset on system one. (I have two other custom ROMs on system 3 and 4. will it also clear all the other ROMs installed on other systems also?
3. Format partitions on system one.
4. Clear system, data cache etc
5. Install ROM and GApps on system 1
6. Keep BMM in main system
7. Reboot and done
Is there anything broken or wrong in that chain?
One more query, can I keep continue installing ROMs on other systems like what I am doing right now in case of retaining stock ROM?
