Is there any way to reset the phone completely, to be just like when i got it the first time? I have flashed hell of a lot of roms on it and now i would like to wipe the slate clean. Is there any way to do it? I know about factory reset. Is it enough for wiping the slate clean.
I don't know much about the software behind the processes and i would like to know if the phone is being damaged everytime i flash a new rom? And would flashing the stock rom reset all the system files?
And i confess, I am a noob. I would be happy if someone can point me in the right direction.
From what I understand if you wipe data, cache and dalik cache in cwr and flash the stock rom it souls be to wen you got it if you want more peace of mind flash it to a earlier rom and do I upgrade using your phones software program to the latest software there is no damage done, the only thing (well on my type of phone atleast) it might have a glad counter which tells hoe many times its bin flashed but I think that can be reset with a USB jig

Flash your carrier's offical rom from here via ODIN. Wipe data first.

Then you can use usb jib(if original was GB) or Chainfire's Triange away from Market to reset the counter.

I didn't have a prob like this 'til now, but did u try to make a clean full wipe reflash?
Wipe data, factory reset
Wipe cache partition
Format data/system/cache
Reflash Rom (later maybe kernel, too)
U have connection to inet? All settings in set correct?

I don't think it's a problem with the ROM as it worked fine until i tried to dual boot with resurrection remix via siyah 3.1 kernel.that's when the infamous eMMC chip error came up.so i switched back to cmw recovery and sensation. Flashed n wiped everything. But everytime i restart the date and time goes back to the default one. And yes i have set the correct settings and everything.

Get gotbrickbug app by chainfire from the market and check whether your eMMC chip has been fried or not

If your eMMC chip had been fried, you wouldn't be able to do a lot with your phone. I don't understand why you're linking this to your date/time problems. Also, Chainfire's app won't tell you if your eMMC chip is fried, just whether a particular erase method could brick your device.
Well when i enter into recovery, i get three four files missing.Those which you get if your chip is fried. And yourphone can continue working fine with a fried chip.only when the bogus corrupted sector is accessed again does it gets your phone into a Brick.Plus am not able to dual boot in siyah anymore.
Emmc being something to do with cache. I think the local settings like time and date is not getting stored to be brought back during a reboot.

I know you guys have had a lot of these questions, but I need help.
I rooted my S2 the other day with jeboo kernel v1.2a I believe. I installed CWM v0.99 aswell. It was all working fine until I went on to the Superuser app on my phone and said something about binary needed updating. So I continued thinking nothing off it. But now my phone is stuck in the boot loop and I don't really know what to do... I have looked around for answers but I am quite confused by it all.
I cannot enter recovery mode but I can enter download mode. I tried installing the jeboo kernel again but nothing happened. I was going to try installing a stock kernel but I don't know what version my phone is.
All of this probably doesn't make sense because to be honest, I don't really know what I'm talking about...
I would greatly appreciate any help!
Thanks.
Download stock rom from Samfirmware, flash with Odin = clean slate. How ? Thread stickied near top of Q&A.
flash another kernel

if you are talking about your phones os version then it is jelly bean.
flash another kernel with disabled emmc brickbug(Syiah,speedmod,dorimanx...etc)via odin as recovery comes preinstalled then do a wipe data/factory reset.

Omg thank you so much. This worked and got the phone out of the boot loop! Now do you recommend wiping date/factory data or leaving it how it is?

as long as you chose a safe kernel from emmc brickbug you can safely perform a wipe data.

Could you explain what emmc brickbug is?
I don't really want to perform a factory reset - is it recommended to do one?
Thanks.
Edit: Downloaded emmc brickbug check from the play store. Says"NO. Sane chip." I'm guessing that's good news?
there is no risk of emmc bug

emmc brickbug is a bug with internal storage(internal storage chip)witch makes phone dead if you perform a wipe data/factory reset with CWM or restore a nandroid backup(mostly with ICS 4.04 ROMs)it happens to some Samsung phones(edit:even S3 but in different case it causes sudden death[it also means phone dead but it happens even if you didn't perform wipe data or restore nandroid backup]from no reason).
But since your phone is sane chip,you are LUCKY,there is absolutely no risk of emmc brickbug.
Only perform wipe data/factory reset in case of bootloop (especially when flashing new ROM)or when the phone hangs.
Sorry for bad english.

Hi guys, I've owned this tab (p4wifi) for a few years now and for sure loads of junk has been building up in it. I've used dozens of ROMs in the past and it seems to be slowing down. Now the slowness isn't the issue, I just want to revert it back to full, pure stock as in Unrooted stock ROM from sammobile with no user data whatsoever. Exactly like the first day I got the tab, no pics videos or anything that I took.
I live in Malaysia so I'll be using this: http://www.sammobile.com/firmwares/3/?download=5982
So now the problem is how to exactly go about doing this? I'm currently running CM10.2 with CWM installed and I want all my user apps, photos and videos gone too, like everything. I understand that i have to boot in Download Mode and use ODIN to flash that ROM image, but hat are the steps before or after that I have to take to remove all my user data? Would really appreciate it if I could have a step by step procedure.
Thanks alot guys

well before flashing the KERNEL image....
it is not quite necessary to totally wipe the phone..
bt to ensure a clean install it can be done...
while.... since u want to return to pure stock.... it is better to first restore your first cwm backup which u made just after rooting.....
coz flashing a kernel wont remove the custom scripts bt only disable it.....
so wat i say is... first restore ur just-after-root cwm bakup.... after that flash your kernel which u will download from sammobile. com.
and then u will have a pure stock unrooted phone like in the beginning

Do this:
1. Wipe data/factory reset in cwm
2. Wipe system
3. Wipe cache
4. Wipe dalvik
5. Wipe internal memory or sdcard or /data/media (I forgot what its called in cwm)
Then boot into download mode and Odin flash the stock ROM.
FYI, the other guy was wrong, sammobile offers ROMs and not kernels. And, HEY, I'M FROM MALAYSIA TOO!

Thanks both of you Woohoo fellow Malaysian on this legacy tab. Sweet thanks for the detailed procedure, I'm guessing step 5 is the one that wipes all photos and videos? Because normally 1-4 just wipes user apps. Will try it after having my stuff backed up How is the UI smoothness for you on this tab? Just wondering if I'm the only one who feels that mine is very sluggish.
actually, Toldo's stock rooted ICS rom and Omni Kitkat rom are both smooth.

Yup that's the one that wipes everything. Sometimes the tab feels sluggish, depending on what i use it for, like heavy multitasking and such, but overall its pretty smooth. BTW, I'm running SlimSaber 4.3 on my tab. I feel that 4.3 gives the best performance for our tab and 4.1(pershoot's cm10) is the most stable.

If you're going to revert to pure stock, just flash official firmware via ODIN. Boot into stock recovery and factory reset. It will also wipe the contents for internal sdcard.

On stock ROM? I'd recommend A1 kernel or Yoda kernel. Yoda kernel is quite outdated and doesn't contain the l2_hsic wakelock fix if you have the 3g version, but its pretty good. A1 on the other hand, is a fan favourite. Both have performance governors and if I'm not mistaken also powersave governor, but honestly I've never tried trickster mod so I can't tell you that.

Thank you sir, great help so far heh. I ended up flashing the rooted deodexed stock ROM i found in the forum but after flashing I chose to disable stock recovery flash, does that change anything? My first boot wasn't successful so I went to reflash the ROM again in CWM and it got stuck in "Opening update package". I restarted the tab and it booted up normally. Is the stock ROM interfering with the custom recovery? :3

Did you do the usual wipe before flashing? And also what version of cwm are you using? Try using this version of TWRP by kasper_h.

It's alright everything's working now Now another problem popped out I wiped my internal memory which means all my photos and everything non system related, and it did, my tab was practically empty buttt the tab doesn't register it as that ._. The storage part in settings shows that I have used up like 12GB of space even though I have wiped everything clean, I did an SD card folder analysis with ES file explorer and although it showed the same 12GB used, the folders shown do not add up to that, could it be the indexes are not updated? Because I don't see anything that could be eating up all that space

If the sdcard is empty, that means something is hogging your space somewhere in /data. What version of Android were you on before and now?
