would formatting /system in cwm lead to any problem
i want to format /system and then flash another rom
Is there a particular reason you feel the need to format your /system partition? I can't personally see any benefit in it and I've never tried it because it is were all the data, framework, boot image, .res, etc...and build properties regarding your current ROM are located. If you plan on flashing another ROM prior to the format I think it would render it redundant because if I'm not mistaken when you flash a ROM it formats /system anyway. However I could be mistaken as I am fairly new to development.

Just format the system, pull the battery, put it back in, boot into download mode and flash a rom

Hi guys, this is my first post on this forum ( Actually I have benn here for a long time without account )
Alright, This is my problem, I usually flash back to stock by RUU, my Pico has over 100MB free space. A few days ago, I flashed the same RUU, but this time I have 70MB space only, I have cleaned all partitions by recovery and flash again, still.
Oh wait, I just use Disk Usage and check the storage, it's say there are some data(not system) on the internal storage, wow.
Does anyone have ideas?
My Pico cid is Taiwan(621), so I flash TW RUU.
Thanks
before flashing, did you wipe system partition too?

why not sd-ext partition for apps?

I know that and it's convenience, but this smartphone now is just my secondary phone.
And for a odd reason, I prefer not to creat a partition on my SD card, just like to keep it simple and clean.
Looks like I'm stubborn...
So I have a Nexus 4 With Stock 5.1 as my primary (Internal) ROM And CM12.1 as a secondary ROM. I was hoping to be able to wipe /system and then use CM as my primary ROM. I can't swap Primary and Secondary via TWRP due to limited space. Because if I was able to wipe /system, that should give me enough space make CM my primary.
Also, would a factory reset also wipe my 2nd ROM too? Because I was thinking of factory resetting my phone to make space so I could swap but I was just wondering if it wipes my 2nd ROM because I have already copied my data over with Titanium Backup.
P.S. I have backups stored on my PC just in case something goes wrong.
Thanks in advance :good:

Have you tried asking in the Multirom thread for your device?

Sorry didn't think of that. Thanks!

Hi guys.
I am a noob in this, but i have done my research and did what i was told.
i have an I9100 and i have rooted it.
when installing CM12.1 (tried 3 diffirent versions) i am always getting status 6 installation aborted.
can the problem be with the kernels? i tried 3 diffirent kernels for I9100.
Please help
Much appreciated.
Hello,
Welcome to XDA.
If you are certain that the ROMs you are flashing are for the I9100 specifically(not another model), then you may be able to use jrummy's root browser to unzip the ROM zip that you are trying to flash, after unzipping, find the META.INF folder and open it then edit the updater script in that file, then using jrummy's root browser compress everything back into a flashable zip, when it prompts you asking which compression level you want to use, select "best", after its zipped, make sure it's placed on your extsdcard(do NOT put it on internal sdcard). When you get in recovery, go to the advanced options and select the option that lets you wipe individual partitions, wipe the system partition and the data partition(DO NOT WIPE ANY OF THE OTHER PARTITIONS), after wiping the system and data partitions you flash the ROM and see what happens.
If you need help understanding all that, you can ask in the forum linked below.

I hope this helps, good luck.

sorry i wasnt clear,
my phone now has "Kernel_Dorimanx-V10.44-LP-SGII-PWR-CORE_-[08-01]-[26-06]-LP-SGII-PWR-CORE.zip"
When im flashing "cm-12.1-20151114-NIGHTLY-i9100.zip" , i get status 6 error.
i followed the instructions on how to fix it using notepad++, and it still doesnt work. tried 4 roms, same error.
unfortunately my external sd card with the backup was wiped. so i have no rom installed.
did i brick my phone? if so let me know what i did wrong please.
much appreciated friend.
When coming from jelly bean or kit kat to lollipop you have to format system and data partition before flashing. Did you do that, you didn't mention in your last two posts that you did that.

No, those are the normal wipes, I'm talking about the format options. Which recovery do you have? CWM or TWRP?
If CWM, boot to CWM, then choose the mounts and storage option in recovery, in that menu you will see the option to format partitions, format system and data partitions, don't format any other partitions or you'll cause more problems. After they are formatted go back to main menu in recovery then continue into flashing your ROM and Gapps. If it doesn't work after that then there are probably things like your modem or bootloader that need to be updated, if that is the case then it means you need to flash any stock updates that came after Jelly bean for your device(to flash stock updates you have to be unroofed and have an unmodified system partition) and then flash your custom ROM, but you need to check that because some devices can't be rooted after certain updates have been taken, it varies from device to device.
If you have TWRP then you'll see an option saying format or wipe in TWRP, choose that option and find where you wipe system and data(again, do not format any other partitions). Then after format is done go flash the ROM.

Sorry, the format options are in the mounts and storage option in recovery, i misspoke earlier, it has been a while since i used CWM, I use TWRP because of some things i do. Try doing the format system and data and then installing your ROM and see if it works.

Hey all,
I have found myself getting used to this new A/B partitioning scheme and it is great not having to wipe app/user data as it is shared across both partitions. Is there a reason one would need to factory reset their phone anymore?

If you're having issues with your ROM but then you could just as easy do a fresh install

I had to do a full wipe after too much experimenting broke root. If you are changing custom roms a wipe may be necessary.
I wrote up a guide about A/B here: https://forum.xda-developers.com/oneplus-6/how-to/guide-noobs-guide-to-b-partitions-op6-t3816123
