I am fairy new in this and would like to know if anyone can tell me how to do a full wipe and reset of this tab? I picked up a used one yesterday to experiment with. I already have 1 since long but never got to flashing it because of the brickbug thing. So it came with some custom 4.0.4 rom and I flashed JB stock onto immediately with odin but for some reason it seems sluggish and also rebooted itself once where all apps got deleted?!
I read that on stock ics doing any kind of wipe can brick the tab? Is still the same on jb? If not can anything please be kind enough to tell me how to go about completely cleaning everything out? It is to my limited understanding that just flashing a stock rom leaves all kinds of things lurking around underneath? Especially since considering it came with a custom rom on the previous owner my have flashed lots of things without properly cleaning up?
oh and I just got it rooted with cwm so that's done at least.
JB has been reported to be brick-bug safe.
Boot into recovery and factory reset, wipe cache and dalvik cache (in advanced) and reboot. First reboot may take a while, so be patient.
Setup and let the ROM "bed in" and build its caches.
Edit: if you still have troubles, do the above and also format system partition, reboot into download mode, flash firmware with Odin, and 're-flash the cwm recovery.

Thank you for taking the time to answer! This is exactly the kind of helpful info I was looking for.
Would I gain anything from flashing your kernel and is that something you would recommend that I do?

Of course, there's lots to gain or lots to miss out
There are many many features that improve it over stock kernel.
There are a couple small random bugs, but they are also reported to be present on stock kernel.
Please have a full read of my kernel Post #1 to #3 and decide for yourself if it's for you. I've also provided the stock kernel for flashing which I recommend to always keep on your device.
You can flash the kernels via custom recovery (CWM or TWRP) or ODIN.
As always, please read the disclaimer too.
Take your time, and make an informed decision on what best suits you
Edit: if you do decide to flash it, make sure it's the P6800 JB 4.1.2 kernel (NOT P6810 ICS 4.0.4). The are two different threads......

This is a flashable zip that simply returns your kernel and wireless.ko to stock GB 2.3.3 as delivered by LG in the update. This is for people who have played around with custom kernels and wish to go back to stock for whatever reason. Caveat: I have not tried the zip myself but one user has reported he has used it with success. This is a simple flash that simply replaces the boot.img and wireless.ko with the files from stock, so you should have no problems with it.
Disclaimer: I am not responsible if you brick your phone, void your warranty, or any other pain or suffering you may experience as the result of flashing this kernel.
Note: Always wipe the Dalvik Cache when flashing a new kernel. If you don't unintended consequences (i.e., boot stuck on LG logo or boot loop) may result. The first boot after flashing will take around five minutes or so. Please be patient and don't report your phone is bricked while it is still booting and rebuilding the Dalvik Cache, which takes several minutes depending on how many apps are installed.
Please report back any success or failures here.
Enjoy!

I was wondering if there was away to revert back. Thanks alot. Hey i got a question I am still a noob and I just stsarted changing kernels but Have been flashing for a while. I asked whast needs to be done before I flash and was told to wipe cache but nothing else is needed. I am haveing a problem with the new EB 2.1 and trinity kernels. When I do a hard boot to fix data it reboots twice the second one being a normal boot so I still dont have data. Should I try to wipoe dalvik and cache would that fix it if no do you have any suggestions?

ONLY the D. Cache should be cleared right?

Yes. The Dalvik Cache is the crucial thing you need to clear when you flash any system file, kernel, etc. If you don't a bootloop or stuck boot is a likely result. If you flash a different rom then you should wipe the system also to be safe.
reason is because I've been clearing the Cache partition as well, I'm not sure if I was suppose to do that, lol.

No reason to clear normal cache. In fact, if you use Rom Manager, that will delete the recovery it flashed as that is where it keeps it.
i looked through the forum and didn't find this exact question so i'm sorry if it's been posted before.
basically what i'm wondering is if i have a ROM installed, let's just say one of the new ICS ones, and a new release of that ROM comes out, is there a way to upgrade to the newer version without having to install all my apps and stuff again through titanium backup? i hope that makes sense. in other words, is installing a new version of a ROM that you are already using going to be the same process as flashing a new ROM entirely? that could get annoying with newer versions of ICS seemingly coming out twice a week.
thanks in advance!
It's recommended to wipe and reflash, but I just flash over top and if there's problems I resort to wiping. Clear cache and dalvik and just flash over top, your apps will still be there. But if you do it this way, you should not report any problems

Probably could have used search to find this. But typically, unless the dev say to full wipe, when an update comes out for the rom you are using you can flash the update over the older version without a full wipe. You are still required to clear cache/dalvik to do this. If anything that was working before does not work anymore after you have flashed the update over the older version, then you should go back and do a full wipe and flash the new version. I personally always full wipe when flashing a newer version.
Sent from my Inspire 4G using xda premium
It all depends on the ROM and what is updated. Seriously you have to go by what the DEV says in his thread. Some you can update without wiping and some you have to wipe. Others will automatically wipe for you. Best advice is to read the DEV's thread. They should all give you this info. And if you looked over the first few posts of his thread you really wouldn't be asking this question here.
Some mods have the cache/dalvik wipe built in, so just make sure you read through the thread for whatever mod you're trying. Wiping it twice won't hurt, but just wastes a little time.

really? man. I'll make this very simple for you.
1. put rom on root of sdcard
2. boot into recovery
3. wipe data, cache, dalvik cache
4. install from sdcard the zip file
5. reboot.
almost all ROMs except for the PD98IMG.zip stock ROMs are flashed with the above method. Not all ROMs require a full wipe (data, cache, dalvik cahce) when upgrading within the same ROM but it is recommended to do so to avoid any issues. If you're switching between different ROMs, it is required to do a full wipe. Search my good man.

That's a problem on your end, that rom is flawless and you flashed it wrong
This is the guide I used to flash the ROM

I compared it with ones on xda and it was identical but more noob friendly which I preferred. I dont know what I couldve possibly done wrong.. I followed EVERYTHING step by step. I love everything about this ROM except this one major annoyance.

It was a bad flash or bad download. Try to redownload and check the md5, then simply reflash it making sure to follow instructions and wipe properly
Sorry, but may I ask what an md5 is? And the specific ROM I want
http://forum.xda-developers.com/showthread.php?t=1377087
doesn't provide instructions, at least that I know of so I followed this guide
http://www.traemcneely.com/2011/12/27/install-custom-rom-at-ciq-removed-short-review-instructions/
Only problem I can think of that I made was flashing the RC 6.75 Stock ROM and then wiping cache partition and flashing the 7.4 Stock Nonewipeupdate right afterwards which is exactly what the guide asked for. Was I suppose to reboot after flashing the stock RC 6.75 ROM before flashing the 7.4 Stock Nonewipeupdate?

You need to flash the base and boot it before flashing an update, like you said.
Before flashing any rom this is a general procedure
wipe data/factory reset 3x
Wipe cache 3x
wipe dalvik cache 3x
format system 3x
flash radio if need be
flash rom
reboot
dont touch phone for at least 10 mins
set up basics
if it has an update
reboot to cwm
wipe cache 3x
wipe dalvik cache 3x
flash update
reboot
Okk. ONE LAST question. The SkyRocket ICS (2.3.5 Gingerbread) ROM I'm using doesn't have or provide a radio file to DL on the page which I linked earlier. Does that imply that this particular ROM doesn't need it? Or am I suppose to find a radio to flash before flashing the ROM and update?
Thanks alot for your help/advice!! Really appreciate it!

In about phone, what does it say for baseband? Kj2 is the 2.3.5 stock radio
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
If the radio you're using is working and you're flashing from gb to gb, you shouldn't have to worry about the radio. You'll still have the same one. Radios flash separately from roms. I don't think you'll NEED to flash a new radio unless you change to an ICS rom.
Sent from my SAMSUNG-SGH-I727 using xda premium
Android version 2.3.6
Baseband version I727UCKJ2
Kernal version 2.6.35.11+
Build number Sky-ICS RC7.4 Stock
When I purchased my phone and after I rooted it, I was v2.3.5 but after I flashed my first ROM (which is my current ROM) the android version changed to v2.3.6. So if KJ2 is the stock radio for v2.3.5 is there a possibility my problem of not having the att logo and wifi signal on the top of my phone due to not having the correct radio for this ROM? or for v2.3.6 in general? Or is it from what you said earlier, my flashing process was wrong? Or a mixture or not having the correct radio and flashing wrong?

Well, I don't really know whether or not the radio is working. I suppose in my case it is working since I am able to recieve and make calls, text, and go on the web. However, I am unable to see the att logo, wifi/cell signal on the top of my phone. I don't know if this problem has anything to do with the radio though. Sorry for my lack of understanding..
I'm assuming the problem is more my fault in terms of not flashing correctly. I have no idea whether or not I need a separate radio for this ROM.
Sounds like a systemui /frame work problem
Wipe data/cache/dalvik
Reflash
Fully boot
Shutdown
Flash update
Wipe dalvik
Reboot.
The signals at the top wouldn't be affected by he radio. You would most likely get them back if you reflashed your from or flashed another. As long as it's a 2.3.5 or 2.3.6. And also follow the instructions (usually pretty standard, wipe data factory reset a few times, wipe cache partition, advanced, wipe dalvik cache a few times, go back, mounts and storage, format system a few times. Then install zip from SD card) oh and always backup first and make sure you can restore the backup. But yeah if you can make calls and use internet, your radio should be OK.

Not sure the deal with your cell/wifi signals not showing in your status bar, but, the carrier logo could have been removed in the ROM itself.
I would try out the nexusmod zero ics I'm running it now and I like it a lot more than nexus 4. Also when I went from the from you are on now I had to do a super wipe before I could get the ics rom to work without bootloop

Hi everyone, Im relatively new to the whole flashing and custom rom scene. I rooted my wind mobile (Canadian carrier) LG-P999 and ran CMR before trying to flash EGB. I used the instructions on the forum post to install EGB. In the installation process however, It looked like Gapps were already installed, I installed the Gapps I was told to download here http://forum.xda-developers.com/showthread.php?t=1575199 again anyways. My phone will now not start, all that happens when I press the power button is the LG logo flashes, and then the Eaglesblood logo flashes then the phone shuts down. I have the CWM recovery file saved on my computer. Can someone help me unbrick my phone? thanks in advance, and please excuse my horrible grammar, I'm quite terrified right now.
EDIT: I messed around with my phone, and I am able to get into the Android System Recovery. Should I wipe data/factory reset? Will that solve my issues?
First get the rom you want to install on a sd card boot into recovery and wipe and install. If you factory reset it still will try and load eaglesblood. If using a cm 7 rom like eb or hellfire flash gapps right after the rom. Hope this helps

Anytime you flash rom, I recommend these steps. (Some may argue that it's over kill)
Get a Copy of Titanium Backup Pro.apk
Batch back-up all your user apps if you so wish. (These first two are optional, but I highly recommend)
Copy ROM, Kernel, and Gapps to MicroSD card. (EXTERNAL)
Boot into CWM.
Do a Wipe data/factory reset
Wipe cache partition
select advanced-->wipe dalvik cache
mounts and storage-->format /system
Install zip from sdcard (not the apply update option!)
select your ROM, flash
select you kernel, flash,
<optional, if your on March BB and depending on ROM, you may need to flash new baseband.zip, forum search for it)
select gapps, flash
Reboot!
Sometimes upon booting you made need to wait 5-10min for phone to come up and be speedy. Be patient.
Hope some of this helps since your able to boot into CWM, which means your not bricked, yet. I;ve been there in a loop, called it soft bricked. Performed all of the above steps, never had the problem occur since. I jump between two GB 2.3.7 ROMS and two ICS ROMs with ease.
Flashed several ROMS in my life and have not always wiped all data. Mainly i do dalvik and cache. My phones have always work. Now i have a Razr HD with an unlocked BL with TWRP loaded. I cant seem to get past the initial bootup screen no matter what ROM i flash. What am i missing here guys? Do i need to check the "factory reset" in TWRP along with Dalvik, system and cache?

Please explain this further to me. My problem is with 4.2.2 ROMS. The fix above is for folks having issues with 4.3 ROMS. Are you suggesting that doing this will also fix my 4.2.2 problems? This is also CWM while i run TWRP. I did a quick look and the two are setup a little difference. I played around with those highlighted instructions and almost accidentally wiped my only backup of my previous state. I actually thought i was toast but somehow i reloaded and went back to my old backup state.

i could be wrong, but in my opinion having the exact same issue even though its a different version, one of the 2 fixes in that thread should work.
the first fix likely doesn't directly apply although i suggest you ensure you have the latest version of your recovery of choice found here http://www.mediafire.com/download/tt7cwwua49n24uv/Razr_HD_Recovery_Flasher_V7.rar
second fix (backup ALL data you don't want to loose first as noted above), then do a full wipe as listed above, not just a fdr that doesn't wipe everything on the internal card.
the problem at this point is, you are assuming it wont work because of version differences, i am assuming it will. until you try it, i don't see any point in exploring other options, if there are any.
Dirty flashing when you go to different ROMs is generally not a good idea. Even on 4.2.2, it leaves residual data behind. There's a reason that the devs talk about doing complete wipes in their ROM threads, and there's a reason that they tell you not to talk about bugs unless you use their install directions.
