I was quite disappointed by not getting a reply to my questions in my phone section so i decided to post it here, hope you guys'll help me out.
Before i perform flashing a rom, i have a couple of questions to ask you.
1. I'm not familiar with nandroid backup and all that. So if someone can give me some explaination of how it works and what i need to do to have a backup of my rom so i can flash back to orignal one whenever i want?
2. Also i heard from people that after flashing some ROMs, you can't get back to stock rom (recovery), if so then how you know that certain rom isn't flashable
3. Is there a difference between recovering (flashing stock rom) and downgrading? if so then what?
4. How can one brick cellphone and how to recover back, is it easy to brick?
Also some basics if i need to know so that i don't brick my cellphone and can easily get back to my official rom whenever i want. Please do tell me anything which i should know, Thanks !

Hi everyone
I am a noob so be nice to me. I accidently cracked the screen on my Samsung Vibrant and so have a few questions about how to return the phone back to Stock/unrooted (just like befor i flashed). I am fine if i have to lose my contacts, apps. ect...
Background:
I rooted my phone with One-Click-Root/Unroot from XDA (loved it). I then flashed the latest Nero 5.0 ROM from Team Wiskey (Love it). As part of either the root or flashing the ROM(i can't remember which one), I downloaded "ROM Manager" with CWR.
Q #1: Is it as easy returning to stock ROM as just using "Flashing ClockworkMod Recovery" or should I have used "nandroid" (don't know what it does, but I see it talked about) also?
Q #2: I hear people say that you need Odin to return back to stock ROM, but then I hear that is ONLY if you don't have ROM Manager w/CWR. Do I need Odin or do I only need ROM Manager w/CWR?
Q #3: If all I need is ROM Manager w/CWR and it returnes back to what it was before i flashed, can i just us the "Unroot" button on the One-Click-Root/Unroot"?
Q #4(Last Question): Will I recieve OTA's if I have to us Odin and flash a stock ROM, how do I get back to stock and recieveing OTA's?
I understand that there are alot of posts asking how to return to stock but that is from people where something in the programs went wrong when trying to return to stock. I am just wondering what programs (other than ROM Manager and CWR) are need for me to return to stock? Please help, I don't want my phone to be rejected because my warranty is void. Thanks

All thats needed to return to stock is a Nandroid backup of your original ROM.
Oh wait.....
Why do people totally fail at this?
What you need now is an original ROM for your device and then flash it from recovery.
So in other words, I need to download a 2.1 Rom (last version i had) from somewhere back on to my computer and then do the same things that i did to flash Nero 5? Is that where Odin comes in? OR, would CWR already have that ROM and everything all in one package?
Like I said, I am a nook. I am suprised that i didnt brick my phone rooting and flashing a ROM the first time. I may be pushing my luck going back to stock. But, it needs to be done if i want my phone fixed.
I would have a look HERE, in the Samsung Vibrant forum. I'm sure you'll find an Official ROM to Flash somewhere in there.
You would just put the .zip on your SD card, restart to Recovery and select the option to Flash from SD
Okay, i am getting it now. However, wont the "Update.zip" (Nero 5.0) be there on my SD memory already? Will i damage my phone if i delete the "Update.zip" and put in the Stock.zip (then do the recovery thing)? So once i get the Stock ROM uploaded on my phone, can i just use the one-click-unroot (from XDA) to have my phone be unrooted and new just like it was when i bought the phone? Will i get OTA's?
Thank you for your help, i am sorry for bugging you but i feel like i am starting to understand it more. These are probably the last questions that i have....probably
I need to return this phone. Bad pixles. I have unrooted it and restored the stock 2.2 rom nandroid. But this phone was shipped with gingerbread. I can't get it to update using the LG software. It says my software is up to date. So I guess I have to root again and flash the stock gb. Will someone help me locate stock gb zips or nandroids?
you have to do some trick with that lg updater to get it to work. Atleast, I had to. If i can find those steps I'll posted.
try this: unless you found a gb zip..

or here are the zip files..

I havent looked but I am sure there is a nandroid or.zip of stock GB in the dev section. If not I just returned my phone to stock because I got a new one and I just wanted to mess around so went to my original GB from befor I played witht the phone and did a factory reset then made a nandroid copy of that on my old phone because the new one was used and the person had someone else do the rooting and flashing for him and they never made a backup of the original. So I took the nandroid backup from my old phone and restored it on the newer one and it worked perfectly. So If you need and it is allowed I can post the copy of that nandroid backup and that should work I think.
Note I am not an expert so if anyone knows better please chime in. But I think that should be okay to send back for warenty exchange. Unless they really look they wont know the difference. I'm sure that they can always tell if they try jhard enough. So when you are on the phone with them make sure you are polite and dont lose your temper for any reason because that will m ake them look harder for a reason not to help you. Thats just my advice. Good luck
You should flash the development section on your phone
Thanks. I cant seem to figure out how to flash those bin files
Now I've done it! I found this file 2x-v10b-1300166062-nvflash and flashed the "flash" app. Now my phone thinks its a p990. What have I done! How do I reverse this! It wont let me flash clockwork recovery anymore
HOT DAMN! I GOT IT! Finally found exactly what was looking for!

New to Android, about 3 weeks now with my Rogers 1727R. I've been trying to grab all the good files and build my understanding of returning my phone to it's stock ROM if I have to return it or if I brick it etc. But I seem to have downloaded, from this forum, so many files, with different names and files sizes, I'm confused about what does what. So I'm asking any senior people here if they can tell me what I have, what it does, and whether I need it. Here goes:
Stock_ROM_SGH-I727R-UCKJ2-k0nane.7z - Think this is a stock ROM but un-bloated. It's 257 MB.
i727_stock_kernel_odin.tar - It's 10 MB, appears to be a stock AT&T ROM, but perhaps just the kernel, not the whole ROM?
Stock Recovery.tar - It's 6.08 MB. Downloaded it today.
Nandroid backup - 841 Megs with data.ext4.tar, system.ext4.tar, boot.img and recovery.img which I thought was a complete image of my ROM.
Look at the size differences. From 6 MB up to 841 MB. What the heck are all these files?
please dont cross-post.....
I was wondering the same thing. I rooted my Skyrocket but in the instance that ICS is available before more custom roms, I may want to unroot. I can't find much information on this. Only how to root for which there is good information and tutorial videos. The size of the different recovery files seems to vary quite a bit.
You do not.need to unroot to take an ota update. You just cant delete any bloat. And gota have stock recovery..... so freeze bloat dont delete. But if you do you can always odin the stock tar
I thought when you flash ClockWorkMod (recovery.tar) that that replaces your stock recovery. Or do you still have the stock recovery just with CWM added?

Yes when you flash CWM you replace stock, do not take an update if you are using CWM, flash back to stock recovery first if you think you just have to have the #.#.2 instead of the #.#.1, to me its not worth it. Once I flash I don't go back to stock. The developers here are amazing.
@ harry_fine, be careful, or you are going to end up with a $200 paper weight. I know how confusing this stuff looks when you first start. Do you're research, make a plan before downloading random stuff you know nothing about. I like to play it safe. I read the posts in the developers section a few times a day for a week before I even start to flash a phone. Most all developers that post things give a very in depth description of what it is they are making available READ IT ALL, and follow directions posted. If i see something that looks interesting I just let it sit a couple days and read what people post about it. If all seems good and there are no major problems I give it a try if not ill let it pass. I have yet to brick a phone (knock on wood). I hope this helps.
BTW
Stock_ROM_SGH-I727R-UCKJ2-k0nane.7z -its a ROM, the post where you got it should tell you whats in it
i727_stock_kernel_odin.tar - this is a stock kernel, I like to think of them as drivers for you phone, install with odin
Stock Recovery.tar - this is a stock recovery you need this if you have installed CWM but want to instal an update, install with odin
Nandroid backup - this is something you should make using CWM before you start flashing a ROM just encase the ROM jacks up you phone you can reinstall
Thanks for explaining that. I am still trying to get the hang of everything myself. I read the Rooting instructions and watched several how to videos before I even considered taking the plunge. I am still a little confused about some of the terminology but I am learning by the day.
The only reason I would consider going back to stock would be if ICS is available before CM7 or CM9 on Skyrocket and then I would want to try it out.
So, if I were to flash back to "stock recovery.tar" (Does the name matter at all?) and take the update, that would would mean I was unrooted again right? Then I would undergo the same procedure to flash cwm and then Superuser?
If I use a custom kernal can that stay the same or does it need to be stock as well before installing an update or new rom?
I don't pay that much attention to the "return to stock threads" since I would never risk it for an update, even ICS, but from what I understand If you wanted to take the update you would need to put the stock recovery (name may not matter but why risk it) and stock kernel back in. You would still be rooted, and need only install CWM if you wanted to instal another ROM later. I think. If I am wrong someone will correct me, but that should be that.
Then how does one completely unroot if they wanted (or needed) to?
To unroot you odin the stock tar

The stock tar in the unroot reaturn to stock fix soft brick thread. Is the factory firmware the phone comes with.....stock recovery not rooted
Hi everyone,
I hope this hasn't already been asked, I tried searching.
I'm wondering if I can flash an N7105 rom to my N7105T (Note 2)? From what I understand, the difference is the modem. Could I pick up a rom with no modem, or alternatively flash the stock modem back after flashing the rom?
I'd really like to dig into Android and get to know the technical workings, custom roms seem a good start but I'm afraid of bricking it.
I have TWRP and will take a nandroid (including EFS).
Another way of putting this might be 'is there a checklist I can follow to make sure the rom will work on my phone'?
I'm trying to learn and work out all the terminology, but this is all new to me as my technical experience only goes as far as rooting.

Good day everyone, just got my note pro WiFi version? Already rooted and has custom kernel civz, tablet feels slow so I'm planning on changing rom maybe lineageOS but I'm concerned about the procedure because I'm not sure where I'm standing with every change done to this device, any help is appreciated I just don't want to brick this device trying to flash a new rom.
Currently it's running stock rom 5.0.2, 3.4.39 civz kernel and knox 2.3, if someone could provide a step by step on what should I do or check in this device to be on the safe road id really appreciate it. Btw I don't even know what recovery I have or how do I access it.
Bump
honestly most samsung devices are the same so id suggest getting the full stock system and using odin to revert to stock, from there start by getting a custom recovery and seeing what else you need to set up your rom
someone correct me if im wrong
heres the page for official stock "images"

someone told me that I just need to install twrp as it is and start flashing roms, dont know if this the best way to do it what do you think?
It could work just keep in mind that you don't know exactly what the previous owner did to it so if they installed a custom kernel you'll be stuck with that, could be a good thing could be a bad thing
You could always give it a shot and if it gives you problems go back to stock then TWRP then start rom-ing
