I've a two-year old Nexus S, which needs to be returned to complete stock, unrooted and un-recovery'd. I didn't root or install the recovery mod myself, so am at a disadvantage when trying to remove it. Guides I've seen for full unrooting seem to rely on a version-specific external file, which seems to usually be 9020A or 9023 - quoting the model number entirely, this is a GT-I9020, nothing more, which seems to render invalid all unrooting/stock-restoring guides I've seen. The phone is still running the official Android, in fact it was factory restored a week ago, and is at version 4.1.3. It's updated a bit since then, possibly including the droid version too.
So my question is how do I go about this? Flashing the wrong version of anything is usually highly unwise, I can't find anything specific for this model, and I don't know enough about the details of the matter to judge what's best to do.
All advice much appreciated.

Shall do then, I need to wait about a week before I can in any case (need the phone as-is for app testing), but that does look promising. I saw it a while after posting, but wasn't sure if it was genuinely as good as claimed, or suitable for this version - I'm very wary of bricking the phone.
Many thanks.

It is genuinely that good if you read the instructions carefully. I use that toolkit myself for more than a year now and I recommend it.

my dad is going to get me a samsung captivate for my birthday next week, and I really want to get the most out of the device. I have several questions that I could not find the answers to:
1. what is the chance that loading a custom rom will brick the device? I see a ton of disclaimers on rom pages and stuff. how dangerous is this?
2. can you fix a "bricked" captivate? is it possible to flash it back to stock, or does bricked mean perminatly dead?
3. how long will it be until there is a gingerbread rom? I wanted to get the nexus s, but I have to go att. how long will I have to wait for that gingerbread tastyness?
thanks for the help.

1. There is always a chance to brick your phone even if it is .00009% it is still there.
2. Make sure you can get into download and recovery mode with the 3 button combo. As long as you can get there then you can just about always recover no matter what you do to it. Key word being almost. There are also other ways to recover, look around and I am sure you will find them.
3. That part is still up in the air. Untill we get a full port. Right now we are still waiting (well at least some of us) for an offical 2.2 update let alone a 2.3 update.
Make sure you read at least the first page in the rom thread you are gonna flash for any extra instructions
so pretty much it is unlikely that I will brick it, and even if I do, it is possible to fix?

It is highly unlikely that you will brick it. Most bricks can be recovered from. The only time I have not been able to recover is when att did the OTA and it bricked my phone and I didn't know about jtag at the time so I sent back to att and it was replaced. Is it 100% umbrickable? No but i would say 99% as long as you read up first and follow the directions to a T you will be fine. I have flashed about 1500 times and nothing i could not recover from
Sent from my SAMSUNG-SGH-I897 using XDA App
thanks. I just wanted to make sure that it was fairly safe to modify, because the phone is not cheap,and it would kind of suck to brick the device 10min ito owning it.
ya I was the same way as you, kind of nervous about bricking my new phone. Just read up on all of the various rom threads. If you have a good idea what you're doing the chances of bricking should be quite small.
I agree (with all of the above) and there is an excellent how-to link to YouTube vids in the Development section (too late and heading to bed or I'd link it) that steps you through rooting and installing ROM. I've been there, done that but it's a great reference for anyone thinking about installing a custom ROM....nice to SEE someone do it to ease the fears.
OK so I followed a youtube video tutorial on rooting,and I think it's the boot.img that messed everything up. It would boot up before but it was stuck on the Google screen, the OS didn't load. So I found a GRH78 or something Nandroid backup and ran that, but the capacative buttons don't work, the screen isn't calibrated correctly and the phone radio isn't correct either. Then I remembered my Nexus S was the newer GT-I9023 GRI54 and I need a GRI54 NANDROID stock backup (which I can't seem to find!)
Guys, what do you suggest I do at this point? I can't revert to stock (I've been trying)
I just got this Nexus S and have been spending hours trying to restore firmwares, finding it online, but now I know I need the GRI54 Android 2.3.3 backup, and if anyone has that I'd be super happy
I really need help
you most likely need the 9023 method of rooting
see the stickied guides
I fixed it. I downloaded a GT-I9023 GRI45 firmware file off of somewhere here (<3 xda forums) it wasn't a nandroid backup, but I used the clockworkmod to install it and surprisingly, it booted up again. (of course, I had the crappy 2.1 installed before so maybe this acted as an 'update' and fixed all the problems, but anyways it works smooth now as it did before )
I knew I could figure it out.
Not to be an ass, but I think there's a lot of difference between bricking a phone and being unable to boot. You've never bricked your phone, since you could still switch ROMs by using the Recovery.
This is a misleading title. Bricking is when you just can't enter not even the bootloader/Recovery.
you are 100% right
unfortunately many people keep getting those 2 terms confused, and use it inappropriately
every body needs to chip in and help newbies learn the correct terminology.
thank you

Looks like I've managed to act and look like a fool...
I tried to root my Nexus S with Superboot, unaware that it was version-specific (I should have known that ). To make a long story short, I tried to root my phone with Superboot which is written for android 2.3.3, while I'm running 2.3.4.
The phone can get to fastboot/recovery, but won't boot. I googled to find how revert to a stock 2.3.3 or 2.3.4, but somehow did not find what I was looking for.
Phone was vanilla, I hadn't installed anything specific on it besides twitter, FB, etc.
From a powered-off phone, how would I manage to revert to a clean phone ?
Thanks for your help, people.

<EDIT:
All the solutions I've seen required CWM or similar, and a rooted phone. Since my problems started because I wanted to root my NS, I figured that I was out of luck for a while, and a non-working phone was out of question.
I went at my retailer and managed to get a new phone free of charge I *****-footed around the fact I was installing an unsupported (by the carrier) update/app, the clerk wasn't very familiar with the NS so it went well with them and they gave me a new phone

Hi all,
I'm attempting to upgrade my Galaxy S Captivate (Rogers) 2.2 stock phone, although it is rooted and unlocked currently. I've read many of the plethora of threads both here and elsewhere, but in all honesty it is a bit overwhelming and I was hoping to get some clarification on some of the specifics and was hoping people here could help.
1) I was hoping to upgrade to 2.3, either stock or a custom ROM. Which ones are good and stable? There are really so many now, I would appreciate a few suggestions. I've looked through many of the threads, but can't really make up my mind.
2) After I choose a ROM, what are the steps for my phone. Should I unroot? Or at least remove the unlock? I was hoping to maybe just have a list of things I should look for in the guides so I know that they're accurate to my specific device and setup.
3) Just to confirm, I should be able to root and unlock with the new ROMs on 2.3, right? Same for lagfix, that was pretty damn useful.
4) Are there any modems which are better than others? Do I do that separately?
Sorry if I seem a bit confused here. Any help people could provide would be much appreciated.
Thanks!

Most (not all) kernels have a lagfix (EXT4 file system) option, some don't. It seems RFS has been behaving well for most on 2.3.

Every ROM will have one preloaded by the ROM dev. Modems are very often (geographical) area specific. They're quick and painless to flash so try out a few.
Read/study to info guides and tech terms. And especially- always follow the instruction of the ROM dev before installing- it will help you tremendously.
Thanks for the reply mate. So, I was thinking of using continuum, and I was just hoping to confirm everything as I understand it.
I'm looking at this thread: http://www.team-continuum.net/forum...ses/(guide)general-installation-instructions/
And at this thread: http://www.team-continuum.net/forum...lease)(rom)continuum-6-1-xxjvq-android-2-3-4/
1) My device is NOT the i9000, correct? (Galaxy S Captivate from rogers, I think it's the i896?)
Current Firmware: 2.2
Baseband: I896UXJL1
Kernel: 2.6.32.9
Should I have any problems?
2) I shouldn't need to re-lock my phone or anything. I use titanium backup to copy everything off my phone (I just used the batch backup)
3) Then I update the bootloader with this one (I897UCKF1), and I assume I just download and run the executable while connected?
4) Then I flash the non-i9000 kernel with odin?
5) Finally, I put the phone into recovery, and install continuum from the SD.
6) What apps do I restore from titanium? Just the apps? Or can I move some system settings over too? Might be a bit dangerous.
7) Does doing all of this wipe everything on my internal SD card? And should I take out my external SD before doing all this?
Is that correct, or am I missing something?
Thanks!
Problems can always happen with humans in the mix, but if you follow proper directions you shouldn't have any.
1. No problem there (see answer 3).
2. Make sure you copy your Titanium backup file off of your phone as you will wipe everything during the ROM flash. Not sure what you mean by "re-lock"...
3. Again, just follow the instructions to the letter- icezar (Cezar - Continuum) does well to explain the process in his thread.
4 and 5. See answer 3.
6. Apps only. I may be corrected on this but I believe going from 2.2 to 2.3 it may be best just skip any data at all. As a general rule there are very few scenarios where you would ever load system data from Titanium Backup.
Everything you asked about could be answered by spending some time reading the forums. As for which ROM, only you can answer that. There is no "best" ROM because each person has different needs and ROMs can run differently from phone to phone. Next time, spend some time doing some searches, look through the ROM-specific stickies in Q&A, and read up in the developer's ROM thread in Dev. Personalized service is nice, but this is more of a do-it-yourself forum with helpful, unpaid volunteers.
Yes, and Kona was very helpful. Thanks for that mate.
As I mentioned before, I had indeed read many of the stickies, but there are simply too many versions of the same information and I got a bit confused. It's especially hard when the same device has many different models, and each model can have multiple ROMS, and each ROM has many different versions. Factor in unlocking and rooting, and there are a vast number of possible setups. For someone who hasn't loaded a custom ROM before, that can be a bit daunting. Even the threads that try to keep things in one place can sometimes add to the confusion.

That's why it's better to post to an existing related thread rather than start a new one that just ends up adding to the clutter.
I have never rooted my phone before, but would like to do so. I'm running Android version 2.3.6 can someone explain to me what to do or direct me to where I can find out how?
Go here . http://forum.xda-developers.com/showthread.php?t=1340526.....it has complete very clear easy to understand directions of how to root.
I was just reading that thread and I seen someone posted that a one click method would be up but I couldn't find it?
Thee acs easyroot one click does not work for 2.3.6
Got it thanks
So I see that it says you need knowledge with the use of ODIN which I don't have so do you still think I would be able to do it?

What answer are you expecting? I know that sounds incredibly criticizing, not my intention, I promise. I got a laugh. I'm just saying think about it.
My advice though is to watch someone do it on youtube. Even if not for your phone it will help give you an idea of the steps needed and about how long it should take (very useful if something goes wrong and you find yourself sitting and waiting and worrying about how long it is supposed to take)
If you can be patient and follow steps, I'm sure you can. Everyone has a first time.

Yeah that's the first thing I did before I decided to post. I always try to do my research before finally asking a question. I read that rooting is different for all phones so I thought why watch a process if it's going to be different from what I will actually be doing it will kind of confuse me even more. Also I search on YT and there were only 2 videos that I found for this phone and both were for version 2.3.5.

You might be surprised how few people research anything before posting. There was a post last week about a guy who bricked his sgsii by flashing a file for a lg Optimus. Then got mad when people said that was stupid.
You're already ahead of the curve with what research you've done.
The nice thing about odin is it's samsung specific software. There may be different details for different phones, but how you connect the phone, the file type you choose, and buttons you do and don't select will be the same. If ever in doubt ask a question. Silver03wrx is easily one of the biggest helps here, much less the rest of the community.
Just know that for now, there's no way to root without tripping your flash counter.
Sent from my páhhōniē
So there is no way to root without modifying recovery? I would like to preserve my ability to update ota or potentially reverse the process.
You can follow those insruction with odin. The after you flash the superuser zip you can flash stock recovery tar found here http://forum.xda-developers.com/showthread.php?t=1360943.
And fyi anytime you odin the stock firmware .tar it takes u back to complete stock . Beware though in order to be able to take ota updates u can not delete bloatware. Just freeze it. You need stock recovery and bloatware intact/frozen to be able to ota update
so with a fubar'ed flash counter, i can still receive ota updates? also, will this custom recovery alter my efs folder at all?
All u need to do is have stock recovery and all bloatware to recieve an ota.
Thanks again for your help. This is not the case with my captivate so I was a bit concerned.
Looking through many post, all of them seem rather old, Im finally ready to root my tablet, Im tired of all of the lag I get and it seems as Samsung has let the 12.2 pro die.

Yep. My faith in Samsung hardware is hit or miss, but my faith in them having too many models for them to keep up with is starting to wane.
Anyways, I had no problem getting TWRP on it, and flashing SU. Just follow the post and if it doesn't show up on your computer, try other USB ports. For some reason these samsungs are picky. I had to try three USB ports to get it to register in Odin. After that it was no problem. I verified it with JRummy's tool, and have run other root apps, and it took just fine.
I wasn't able to get xposed working, but that might be an issue with the stock ROM. No big deal though. Backups, moving apps to SD, and such, are all capable with root and TWRP, though it would have been more tidy to have the SD card as an extension of the on-board, I can live without it.
If you need my stock ROM build info it's P900UEU1COI1_P900XAR1COI1 (cellular south). There are two US ones I see available for 5.0.2, and have no idea what the difference is, but that one works fine for me. So if you have to Odin first, or after, that one seemed to go well for my US P900. Use that info at your discretion, because I can't see your current build info.
Thanks for the info

Same build here.
Follow the directions carefully (you likely don't need to do the first area as you're already up to date), and you should be all set. Just remember to backup everything important first. Since you already have your info/apps in place, and aren't changing ROMS's, there isn't much to it. Don't forget to do a backup using TWRP after you have everything up and running. You'll want to download busybox from the app store, after you're rooted.
Careful if you decide to go with a custom ROM after. I didn't have much luck with cyanogen mod 13, because it knocked out a lot of my Spen needs, and there are a fair number of reports of random reboots on the one I tried. Hopefully that will change and I can update to 6.0.1 when/if it does.
For you, there shouldn't be a need to wipe data or factory reset, but if the lag continues you may want to wipe your cache's once you have your nandroid backup.
PM me if you run into any issues, or better yet, with any questions you're unsure about, before an issue happens
