Hi.
If you are gonna flash stock ROM via flashtool, it won't touch your bootloader and you will loose everything on your phone, not what you have in your sdcard, but everything else. And yes this will fix all other problems. Your phone will be like it when you buy it

Recently , i have been watching some Cyanogenmod 9 ICS 4.0.3 ROM video and it seems to be cool. Well my question is if i flash the Cyanogenmod ROM , can i re-flash the stock ROM that i had?
And is it safe to flash a custom rom?

Cool as in not overheating ???
a wipe and flash of stock rom will remove custom rom .
Root and custom roms void warranty and have a slight risk of bricking the phone .
But are usually recoverable .
You need to read the faqs and guides and understand the CM9 instuctions first .

to flash cynogen rom first u have 2 root ur phone please find the thread in original devlopment section regarding the same
u can reflash ur stock rom by dwnld the releavant .tar file adn flash the same thru odin
You can re-flash the stock rom, but just be sure to know which one is your stock rom. Go to settings, about phone and record the info there to be safe. Also back up your current rom using CWM.
There are always some risk in flashing a rom. Some people dont read instructions and cause problems on their phone, some people flash a rom not built for their phone (i9100 VS i9100G), etc.
Yeah i have rooted my device with cf-root. Thanks guys , i'll read some guides about cyanogenmod and flash it.
If your are currently on GB stock rom, Cyanogenmod developer recommends to install ICS bootloaded first,
You should be able to reflash your Stock ROM veriosn from ODIN, as well as custom roms from CWM...
What is bootload? o.o
My current firmware is ICS LP7

No they say to have below some specific ics boot loader, no mention of upgrading your gb boot loader, unless they changed it.
Plus I yet to had any issues with the latest ics or gb bootloaders..

I think he meant boot loader.
But since you already have ICS, you won't need it. Just take the latest CM9 nightly (or ROM based off it), and flash (you'll have to wipe cache data and dalvik too eventually). Make sure you make a full backup of your current stock ROM through CWM as well.

I refer this guide actually : http://forum.xda-developers.com/showpost.php?p=20841817&postcount=1
I dont know its outdated,
as others are sharing their experiance that you could flash CM9 straight away from your CWM since you are already on LP7 with ICS Bootloader.....
I don't get it... What is a bootloader?. I mean when i flashed with ICS LP7 i didn't put a file on bootloader. I just loaded the PDA .tar file and flashed it..
Soo that means that i have to reflash the stock rom with bootloader?

I dont know the ICS package you flashed had an ICS Bootloader already...
I just gave you the link for Original CM9 developers guide...
Just wait for others recommendation who have already flsahed CM9 from CWM....
Hmm thanks . But i have read in the guide that i can flash it with odin , do i still need the bootloader?
I did a search but did not exactly what I wanted.
Have a few questions in mind:
1.Can I Flash any custom Rom with my stock kernel?
2.Will doing the above cause any problems?(brick,bootloops,buggy rom)
3.Also unlocking the bootloader(is it necessary?Please a Noob here)via the official method(sk17i)I heard we would loose access to certain company features(track.id etc)would I loose access to official update of firmware from them?
4.Most of the Rom's featured here have not specified which kernel to be used with them could anyone suggest one which can handle most Rom's?

Please read the sticked threads, everything should be explained there
1. Yes, custom roms for locked bootloader
2. It can cause bricks or bootloops, roms where something's not working can be buggy
3. Unlocking the bootloader is necessary for nearly all custom roms like Cyanogenmod, AOKP, etc. You will loose your DRM (who needs them?) and track id won't work, but if you download the latest version it should work! You can't update via PC Companion, but you can flash official updates using flashtool :good:
4. All the kernels like Rage Kernel, kernel panic, x kernel, if you look in the kernel thread there should be explained for which software version they are...
That's it, but should be explained in the sticked thread, too

But if done properly they would run properly right? Without Bricking the device? Also should I be in ICS(stock) to install any ICS Roms(custom)? Or does the requirements for each Rom different?
I did find some locked BL Roms Thanks:goodSticky Threads)

He should be on ics to flash ics custom roms, because otherwise you could get a bootloop

A bit too late. How to fix the loop? Should I use flashtool to flash the stock rom?:crying:
Or should I use the Sony PC companion to "repair it"
(Note I'm in stock Kernal With root, So will doing it via Sony PC cause more problems?Also since I have root will I be able to use the official updates and Repair options?)

i would suggest u nt to use Sony PC companion after rooting, unlocking BL as FOTA updates may brick ur device
(when u unlock BL its quoted there that not to do FOTA update after unlocking BL)
I dont know it brick device or nt bt why take risk?
Did u make a cwm backup??? If yes just restore it or flash the official ftf using flashtool....
I think I may have BRICKED it!!....stuck at SE logo at start-up cant enter CM recovery!!....I did make a backup in the SD card but since I could not enter recovery no use. I tried to flash the official firmware via PC(flashtool) but it says USB debugging is disabled!
Have I officially BRICKED my device? is there any way to get back to the good old GB and stock Rom?:crying::crying::crying:
Use Flashtool, Flash the Stock FTF and all should be come good again
Or Use SEUS/PCC and try The Repair Option

hi everybody!
I need an help. Sorry for my bad english, I'm only 16 and I'm Italian.
I have an Xperia Mini, it's my first android phone, so I'm not very good at android modding! I downgraded it from ICS (Official) to Gingerbread (4.0.2.A.0.42 build) and I rooted it. Then I installed ClockWorkMod recovery. I don't have an unlocked bootloader, but I want to flash a custom ROM based on gingerbread. If I flash it, can I go back to stock rom with CWM's restore function? And If I can't, can I use flashtool to flash it (I have the .ftf file that I flashed for downgrading)?
Thanks very much.
Welcome to our forum
You can flash a gingerbread custom rom for locked bootloader with cwm, but be sure it is for locked bootloader!
If you take a backup in cwm, with backup/restore -> backup before you install the custom rom, you can restore this backup to go back to stock. Flashing the stock ftf will also work, you have to decide if you want to restore or flash, but if you take the backup in cwm it will backup the whole firmware with all apps etc :good:
Thanks! :good:
But do I need to flash a custom kernel? Or can I keep the stock kernel?

For locked bootloader custom roms it's the stock kernel :good:
For unlocked bootloader roms you need to flash a custom kernel, but this is only possible on unlocked bootloader

Normally it should work, but the problem is there's not specified if it is for locked or unlocked bootloader. It's stock based so it could work on locked, but it is recommend to flash a kernel. You could try it, but it could be you get a brick
When it's bricked, (mostly) you can't boot in recovery so you have to flash the stock rom with flashtool
Another little advice: If you install an ics custom rom on a gingerbread phone it could end in a brick. I had this when I was on locked bootloader, so I updated to ics (while keeping root, how to do this is in my rooting guide) and installed it again.
You can try an ics custom rom on your phone running gingerbread, just install it. But if it won't boot, flash the stock gingerbread rom and update it with root to ics
Ok. But before installing a rom, I have to do a full wipe, and wiping all will delete the CWM recovery?
I think I'll first upgrade to ICS officially. Can I use pc companion? or I have to flash the .ftf file of the stock 4.0.4 firmware with flashtool?

1.) make nandroid backup
2.) factory reset/wipe data
3.) wipe cache/partition
4.) format system
5.) wipe dalvik cache and battery stats.
6.) flash ROM
7.) flash supersu fix, there are lots of links out there just incase you have problems with root. this will solve your problem if u have locked BL
8.) if you lose CWM, you can use led deletes x-recovery tool to install cwm after you boot your rom
BUT TAKE NOTE THAT THERE ARE CERTAIN THINGS YOU MUST DO IN "SOME" Custom ROMS like Hasa(flashing lockscreen after 1st boot)
MAKE SURE TO READ THE THREAD's INSTRUCTIONS FIRST
Ok i read all the guides...now I'll update to ics and root it. Then I'll install a custom rom.

I see a lot of ROMS posted list kernels other than mine (NC2). Do I need to flash those kernels prior to flashing those roms or not?
Also, If I want to go back to a NC2 roms will I night to flash that kernel back?
I am confused, please lmk. Thanks!

No need to flash kernal.
But, If your developer of Rom said that custom Kernal is required then you should flash custom kernal....
For backing to stock rom you need SP TOOLS (Smart phone tool) & Scatter file.
Every custom Rom does have its own kernel included which works perfectly with it. You don't need to flash any kernel. Just if you want to change the kernel you can change it afterwards. If you want to go back to your rom you have had before, just backup your system folder with twrp for example recovery and then you can restore it back. Hope that helped.
I have a Redmi 5 plus, and I unlocked the bootloader to flash custom roms , after that I moved on official ROM but each and every SENSORS ARE STOPPED working except finger print sensor, I don't know what to do:crying: please help me to fix that issue
Ive had the same problem while trying to flash a custom kernal, its a kernal problem.. try to flash the stock rom again.. full flash it will restore the sensors.. or else flash boot file from the stock rom
