Updating to new firmware/kernel - Galaxy S II Q&A, Help & Troubleshooting

Hey all so after I update my firmware to XWKK5 do I have to wipe everything while in recovery mode is it really necessary?

What do you want to achieve with deleting all from recovery?
If you've upgraded, then the phone is in the version upgraded. If you delete all from recovery, you have to reinstall the entire ROM or the phone wont boot...

Thought I had to Wipe Data / factory reset and Wipe Cache Partition?

Instructions are to be followed .
Custom roms usually ask for wipe but not stock roms .

You don't need to do that if you are upgrading from a Stock ROM. If you chose the wipe version of ROM for flashing then it'll automatically wipe you device. If you use non-wipe it'll upgrade and everything remains same.
Wipe is only recommended when you are switchin from Custom to Stock or vice-versa else after a version downgrade say KK5 to KJ3.
Hope it helped.

Best way to flash back to stock rom?

What would be the best way to go from any custom rom back to a stock rom. Wipe data, cache, dalvik cache in recovery, the shut down phone and flash stock rom via odin? Or should I also wipe system before flashing?
Thanks!

You don't need to do any wipes through CWM if you are going to be flashing a stock Odin rom, odin automatically takes care of all that stuff. You can just boot your phone into download mode as is and flash the odin rom.

Btw, your title is a bit misleading/ confusing? Aha, you ask "best way to flash back to custom rom" ??
Yes that was indeed a bit misleading, corrected!

[Q] How to remove a ROM so I can flash with a different ROM?

I flashed my S2 yesterday with CheckROM and I like it and everything but I'd like to try MIUI today but I'm not sure how I would go about this? I think I may have to wipe my phone (already have a backup from before I flashed with CheckROM) and then just install MIUI like I did CheckROM? Correct me if there is another way or I'm wrong.
Just go into clock work recovery, wipe data cache, flash miui.

By formats system do you mean wipes everything or just cache?
Let's see.......
You wipe data, cache but your phone can boot, because the OS remains.
You wipe system OS got removed, you can't boot phone.
Wiping system is the cleanest flash you can do.

[Q] Omega ROM flashes inquiry

Hi,
I was using stock firmware up until yesterday I flashed to v5.2 successfully. Everything is working fine. But I just have a question, I remember that after the flash, and the phone rebooted and I connected to my wifi...the phone automatically started to download and install all the 4 apps that i had personnally installed on the stock firmware all by itself ..
I'm asking because I see that there a v6.0 available and would like to flash that. But before I flash, do I need to do the following wipes?
Wipe data/factory reset
Wipe Cache
Wipe Dalvik Cache
If so, do I need to do this for between EVERY Omega flashes to ensure it goes smoothly? Thanks

You should only have to wipe cache and dalvik then flash the ROM. You'll be fine, I also always format cache and system in the mount and storage part of Cwm recovery BEFORE flashing the ROM, never had an issue.

Is that considered a FULL wipe?

No, full wipe is when you delete all user data as well.

Ok I found the definitions of what a full wipe and no wipe is:
Full Wipe Install means:
- Wipe Data / Factory Reset
- Wipe Cache and Dalvik Cache
- Format System partition
- Install
No Wipe Install means:
- Wipe Cache and Dalvik Cache
- Install
Just a question, in the FULL WIPE listed above, where would I find "Format System Partition?" I don't recall seeing that..which category do I enter to do it?
CWM recovery mounts and storage format system .

Thanks, is there any harm if I do a full wipe EverytimeI upgrade an Omega ROM? I just want to stick to one way of things to minimize any issues.

[Q] Twrp recovery -- do I also wipe system before flashing new rom?

Hello. I have backed up my stock rom and would like to flash a new custom rom. Team Win Recovery is all new to me as I used clockwork recovery and Amon RA on my old evo 4g. Before I flash a new rom, I know I'm supposed to wipe cache and dalvik, but do I also wipe system? Thank you for your help in advance.
If you're flashing a different ROM all together, then I usually do Factory Reset, Cache, Dalvik Cache. (in that order)
I don't know that the order matters, it's just my way of doing it, and I've never had any problems.

Thanks for your quick response. Gladly appreciate it! But there's also an option in the wipe menu to wipe "system". In the wipe menu, there's: cache, dalvik cache, factory reset, battery stats, rotation, system. I wiped cache, dalvik and battery, anything else I neeed to wipe before I install a custom rom? In clockwork recovery, all I used to do is wipe data, cache and dalvik.

Yes, when flashing a fresh ROM wipe EVERYTHING, including system. I usually wipe a few times just to make sure I'm starting fresh. I haven't used this super wipe but you can also check this thread

Edit: I don't usually worry with wiping battery stats or rotation

Thank you. I wiped everything and performed a factory reset.
You don't need to wipe system. Any decent rom out there will wipe the system for you before the rom flashes.
If I'm not mistaken, I believe that the factory reset wipes system anyway.
No factory reset does not wipe system. Also do not use super wipe zips. They are bad for you

Factory reset wipes the data partition. It does the same thing as the factory reset within the phone settings. If you wipe system, it completely wipes out the OS, and there will be nothing to boot. Of course you can still get back to recovery. When you flash a rom, by default it should wipe the system for you and replace the system with the rom you are flashing. There may be a case where you are flashing an incremental upgrade, which will not wipe the system.
The reason you do a factory reset (data wipe) when flashing between roms is because settings and other stuff that was saved on the data partition may not be compatible with the rom and cause issues.

Based on what?
Based on what developers have said. Super wipe originated from a CWM issue back on the EVO 4G and people never seemed to of forgotten.

The issue was with cwm not superwipe. The superwipe created for this device works fine.
the issue was with cwm, the superwipe was made to combat that issue. a good dev will set his rom to wipe system. all a user has to do is factory reset in recovery. Superwipe is a unnecessary step and could be bad for the phone if its corrupted or the person who made it did it wrong.
really great info, thanks guys!

Yes. A system wipe doesn't affect recovery. It just wipes the system partition on your phone. The recovery partition remains unaffected.

how to factory reset stock 4.0.4 and keep root?

how to factory reset stock 4.0.4 and keep root?
hi am quite new to the s2, after rooting with Siyah 4.1.5 i am getting constant crashes and freezes, i wanted a quick step to stop guide on how to factory reset the firmware.
i don't mind loosing all apps and data as i can use titanium also all my main data is on my external sd card. thanks
You are asking to do to different things a factory reset will wipe user data only nothing else , you will still be rooted.
go into recovery and clean cache, daavik cache and then do a factory reset. It will store your phone to default settings for what ever stock rom you are on.
If you format the internal storage, you will lose the rom, root and all data on the internal card. You will then have use cwm or odin to flash a new rom and apps.
Don factory reset jus download philz kernel an flash it via odin or cwm
