Hi!
I need some help with understanding of flashing custom roms e.t.c.
If I have 4.3 ( latest official update ), is it possible that I upgrade to CM11 4.4? Or I just can flash roms wich are based on 4.3?
Dont get it!
Thank you for responding!
If you have custom recovery installed, then you can install Compatible ROMs for your device (such as CM 4.4). If you are running stock or another ROM, then by entering custom recovery and making Nandroid backup first, you can install the ROM. To install, read the post for ROM you want to make sure compatible/whats needed (like GApps, etc), download, backup current ROM if isssue happens (to save yourself), WIPE data/factory reset, WIPE cache/dalvik cache, install ROM/etc as directed via the ROM post page. As long as you can meet these, you can flash what you'd like.

Welcome, make sure you do your research though on flashing and the ROM in case there are issues with the ROM specifically (ex. Bluetooth not working, or something). Any one thing missing (didn't flash GApps, ROM problem, etc) can cause issue. If no issues or you can live around them if they exist, then good luck.

Hi
I am new on the SGS2 though i have one Android Tablet.
I have been reading a lot and there is something i have not been able to find.
I want to root, , install CMW and install this custom ROM: Dynamic
http://forum.xda-developers.com/showthread.php?t=1582217
1.- Do i need to install first the CF-ROOT kernel matching my actual Firm to make the root or can i install the Siyah kernel at this will make the root anyway?
2.- If i install the CF-root using ODIN, do i need to install an specific kernel for that ROM? Or most kernels work with most rom?
Thanks.
I suggest you flashing the cf-root kernel with odin then you can install your custom rom from the modified recovery mode flashing the .zip file of the rom.
You can flash the siyah kernel after that, because generally custom roms mount a custom kernel which supports CWM (Clock Work Mod, the custom recovery).
If i helped u, press thanks.
if you are on ics you should be good flashing siyah but most of us here started with cf root

1/ follow the install notes stated for that rom also siyah kernel if flashed thru odin will give you root and install cwm/superuser
2/if you install cf root again follow install notes within that thread and it does say best to use same cf as your stock kernel or find one close to it to match
i prefer to use siyah less hassle but each to there own and everyone has there own choice
Thank you all.
I decided to go safe and try with CF-Root. Now i am rooted and i have installed the rom using the CWM.
Do you recommend to change the kernel again? I think that the rom has its own kernel but i am not sure.
Also something weird happen (little off topic), after wipe and reinstall the rom, i have some apps installed by default, some of them where on the old ROM.
I thought that all the apps will be deleted with the installation of the new rom.
Not sure how to fix it.
Thanks again
Apps will only be deleted by doing a full wipe in cwm. And you dont need to flash another kernel if you only want the root feature.. i think all the custom roms use a rooted kernel... some use cf-root, some siyah, some speedmod etc...
Well, i really prefer to use the features offered by other kernels. I was not sure if i can change the kernel keeping the Roms or if i need to reinstall everything afterwards.
How do i make a Full Wipe? most of the apps are bloatware and i do not want them.
Thanks
im also a noob and i use siyah without changing much
just OC to 1400 and choosing en demand for governor

You must go in the custom recovery and press "Data wipe/factory reset", so you wil have only the system apps, but you must start the phone configuration again.
U can flash another kernel if you want, there's no problem with the rom, but remember to do a dalvik wipe.
If youre thinking about to flash a new kernel, i would prefer to flash the kernel first (now) and then do a full wipe and dalvik wipe. Otherwise youre doing some work twice...
And if youre yet haveing some "bloatware" (e.g. from a provider branded firmware) after wipeing, you can delete them (be careful with system apps) with root explorer... (in "\system\app" folder....

If your happy with the results you get form using CF then by all means stay with it otherwise follow the thread in which your rom is based on users will often leave feedback on there selected kernels and setups like my signature for example check im sure theres users within your choosen thread with the same
I can advise using the kernel cleaning script after changing to another kernel. http://forum.xda-developers.com/showthread.php?t=1363738
This will prevent problems that left behind files from the old kernel can cause.
After flashing the file/script install the desired kernel
Thank you to everyone!

I did the Data wipe/factory reset and everything as per the instructions:
*For a clean installation and no problem
- Download the ROM and put it on your S2.
- Go to Recovery
- Wipe data factory reset, wipe cache.
- In Advance: wipe dalvik cache and wipe battery stats.
- In mount and storage - format data , system and cache
- Install the zip file and you will get the CWM install completed message.
- Select Reboot Now and let the phone boot up to an Android setup screen.
- If there are Update, download it, put it on the phone, go to recovery and install it. Don't do wipes.

I think i am going to make it more than twice.
I will go to other kernel to try them. The battery on CF is not as good as i would like.

That is the strange thing. I am not using any branded firmware, i came from one, but i thought everything was to be erased after the wipes and formats.

I will use this on my next try this weekend.
If i do not understand wrong this is what i need to do:
Review the rom to find a kernel that suits it.
Use the kernel cleaning script
Install the new kernel.
Follow the instructions to flash the desired ROM with all the wipes and formats required.
Anything else?
Hi,
I've recently rooted my phone and installed my first ROM - Resurrection Remix - and it's notified my of an update (v3.1.3) and downloaded the zip for me. My question is how do I safely update RR?
When I first installed it I had to perform a number of steps wiping and clearing things before installing from a zip using CWM. Hopefully I don't have to do all of these as I don't want to have to completely reinstall every update, but do I have to do any of them still or do I just install from the zip in CWM without any other steps?

Have you read the first posts of the ROM thread?
Maybe there is a description of how to install the update.
If not, then you can just flash the update zip file in CWM recovery and try to reboot normally.
If everything works fine ... that's it.
If you have issues, boot into recovery, wipe cache and Dalvik cache and reboot normally again.
If that does not help, then you might have to wipe data (do a factory reset) in recovery.
But I think that these steps are not needed as you are already on this custom ROM.
(Usually you only have to do the complete wipe steps when coming from another / stock ROM - and the other way round.)
Good luck !
P.S.: Always create a nandroid backup before flashing. So you are able to "go back" if needed.
hi friends..
i have sony lww rooted and a flashed custom rom serenity v3 and vegeyance 1.31 kernel.
now i want to try another custom rom but i have some confusion..
should i have to follow all procedure again while flashing another custom rom
i mean i don't want to loose my data and contacts again i have backup but i don't want to do it again
so if i want to flash another custom rom should i have to follow all procedure like..
-flash a kernel
- do a full wipe/factory reset
- wipe cache
- go to mount & storage>format system
- go to advance-wipe dalvik cache
- flash the rom
i know flashing kernel and flashing rom is always important and without it i cant install any custom rom
but i hate the steps to follow between these two steps.....
so friends plz tell me is this compulsory to follow all steps or is there any short way...
thanx to all in advance.....

If you are on an ics kernel, no need to flash a kernel again. If you want to flash CM, then you have to follow all the instructions. While switching between roms, wipe everything except the /data partition. Then install your new custom rom. There is no guarantee that the rom will boot. It is recommended to wipe everything but no harm in trying. It is much safer to backup contacts by going to contacts and export to sd card. For messages you can use Sms backup and restore on market. Use titanium backup for apps. Done!
Sent from my LT26i using xda app-developers app
I would not recommend to format /system. Otherwise you may get a getprop error. The updater-script should wipe /system automatically
Only wipe it if it's recommend in the thread of the rom :good:
follow this procedure bro...
1.Backup
So you dont want to lose data...then first backup your contacts,export it to memory card,
then backup messages using sms backup and restore,u can find that on the play store...
dont forget to make a nandroid backup..
2.Gather info about current device status and the rom u want to flash
then check whether the rom you want to flash requires a different kernel other than the one on your device right now...
if the android versions differ,definitely kernel has to be changed otherwise you can get stuck in a bootloop...
visit the rom thread,check whether there are some bugs associated with your device,download the fixes required if any...
here you might find links to the supported kernels,instructions on installing the rom i.e wipe cache,data,dalvik cache,system etc etc...
download the rom,copy it to your sdcard along with the fixes if any...
3.Start flashing
First flash the kernel...then enter recovery
wipe the partitions that were mentioned on the thread...
then select your rom and flash it..,then enter recovery again if u want to flash the fixes...
4.Restoring..
install titanium backup first,restore all your apps from the nandroid backup,then you can restore the contacts and messages...
you are done
i know its a long procedure,u can get really frustrated until you hit on a stable rom and kernel...but i dont think there is any shortcut to this..
Sometimes the updater-script in your new rom may have been set to delete data,system,cache,dalvik cache. So if u don't want them to delete u have to edit the updater-script.
Hi!
I want to do a
COMPLETE REINSTALL
of my Neo V.
I use AOKP ROM.
What is the best way to start here?
1) using flashtool by DoomLord and flashing old stuff before doing a full wipe?
2) only full wipe via recovery and then install the ROM?
3) factory reset, then full wipe, then flash ROM?
Whatever.
I am overwhelmed of the possibilities in doing it. There are many ways, but I want to ensure that everything is set up correctly from the start.
All my data and intern ROM stuff is saved via Titanium.
So don't be shy to recommend the best and cleanest and deepest way to do this!
Thanks a bunch for your advices!
All the best

This is the usual procedure when installing a (new) ROM.
The other day I saw something in Flashtool which said that my device would still be a ICS device. There was nothing mentioned that AOKP was already in use. Or a JB kernel. There was still a footprint from a ICS ROM I used ages ago. I want to change that.
This is my problem: I want the device to be recognized correctly everywhere.
So, the advice you gave me would be the deepest I can do for the device itself?
I think I did this one or two times, but these footprints from former ROMs and flashing stuff are still there.
Thanks in advance!
Flash stock firmware (.587)
Copy ROM and GAPPS on SD
Flash a kernel in fastboot
Go to recovery..
Full Wipe.. install..
it should be good..
Check in Flashtool once the mobile is settled down. it should recognise as 4.1.x or watever!!

It is important to mention where to get this Stock ROM: http://forum.xda-developers.com/showthread.php?t=1678690
What I already got back to normal is the indication of Wifi: It never was blue and full but always grey.
I didn't check my version in Flashtool yet as I am still restoring my apps and settings.
Will report back if there are any issues or new information.
See you around.
I installed one latest firmwares to try it, and hate it. Anyway I went to install CM13 even blisspop and it won't install and gives error 7. I can odin stock rom but can't flash any asop is my sm-g900T dead lol.

Are you doing a full wipe before installing any AOSP ROM? I.e. in TWRP, there is an option for Advanced Wipe. Before your first time installing any AOSP ROM, coming from stock ROM, you must wipe system, data, cache, and dalvik. Also when you say latest firmware, you mean FOL1, right? Because that's the latest. Finally, are you using the right ROM file. This phone's development codename is klte, as opposed to kltespr, kltedv, kltevzw, klteusc, etc.

Yes I've install hundreds of roms on this phone, I know it's klte I do a full advanced wipe in twrp
I believe it was FOL1- I've never had a problem before. Figured maybe new firmware made impossible flash asop or something.

I googled it and error 7 is a problem with the assert. So double check you have the correct ROM file, then edit the first line or two out of the updater-script (located in META-INF/com/google/android/)
