Question: Rooting and Cyanmod - 2.1 - Captivate Q&A, Help & Troubleshooting

Hey guys! I was told to come here for help on rooting and modding my Samsung Captivate! I've been a long time member on overclock.net and I have heard nothing but good things from XDA so I thought I'd stop by for some quick questions.
What I am looking to do is mainly use the free tethering that cyanmod offers. I totally am not willing to pay ATT $30.00 a month for tethering.
I've been reading some post's on here and other places, but I would like to get your input on the best ways to do this without bricking or messing up my phone.
I apologize if there is already a sticky for this but I honestly didn't see anything I was 100% about.
I am currently running the 2.1 on my Captivate and the only thing I need to possibly back up is my contacts.
If anyone would be kind of enough to point me in the right direction I would greatly appreciate it!
Thank you,
Obzz/THEoBZ

If you are on 2.1 that is an easy place to start. If your not worried about backing up anything besides contacts, there's no real need to root before flashing cyanogenmod. If you do want to back things up such as your apps, wifi networks, etc etc I'd highly suggest rooting your device. Regardless, all you need to do is have a clockworkmod recovery zip on your SD card. Boot into recovery flash the custom recovery, then wipe data/factory reset, then flash you're desired ROM.

Oh ok! Is there anyway I can save them without a SD? Like to my computer or something?

You can use the internal SD and export it to it! then transfer to the computer. It is contacts>menu>IMport/Export>export to SD card

Or just sync your contacts through your google account that's the easiest way I find.

Alright, I went ahead and just saved them to my SIM. Question, for some reason when I try and use my internal SD it says none is available.. How do I fix this?
Also will I need a extra SD card to install cyanmod? The only instructions I can find is that way..

You won't need another SD card. The internal SD card can be used to store the cyanogenmod zip file. I'm not sure what you mean when you say the SD card cannot be found?

I need some help please

I've been on XDA today for atleast 3 hours and havent gotten anywhere, I have owned my G1 since dec. 08, rooted it, and kept the firmware at 1.1. I have jesus freak recovery 1.41.
Like I said, I've been on XDA forums for 3 hours already and haven't had any clarity what so ever and am just frustrated right now. Without being 100% I managed to upgrade to 1.6 withy cyanogen 4.2.15.1 I lost everything that was on my phone, it hurts but I'm just frustrated to the point right now that the phone is functioning slower than before and theres lag between the screens and functions. With the upgrade, all of the phones original fucntions "contacts, alarm clock, calculator, etc." force closed and nothing worked, i tried to factory reset and because of the stupid sync issue from the begining skrewed me and about half of my info saved to my google account. I'm so frustrated right now.
I need to know how to install the newest recovery to hopefully work with Nand because I had to Manually rename the DRC83_base_defanged to update.zip and then had to manually rename update-cm-4.2.15.1-signed to update.zip to install each one at a time without having the ability to freely choose what zip i wanted to install.
I haven't been able to find what issues there are with using another phones firmware on the G1, i've seen the Hero firmware, the home screen looks gorgeous and runs like a dream, but I haven't been able to find anything saying that it is okay or a BAD idea to attempt to install it, also I havent been able to find any info on finding the newest g1 firmware or any mods to be able to make the g1 firmware look like the hero, or any other android platforms. I have just found constant cooked firmware after firmware with a hard time decyphering why one may be better than the other. If someone could help me, I would GREATLY appreciate it.
I continute to run into threads "how to root" or "down load this, and download this, and assuming you have something with options you dont have, make it work like this"
Please someone help.
First you need to upgrade your recovery b/c the one you have is very very Ancient with a capital A....You have to wipe before you flash the defanged then flash cyan w/o rebooting.
I want to upgrade my recovery, but I haven't found anything that can help me upgrade the thing. any links to tell me how to do it? and is there no order that I have to install the firmware? instead of having to go from 1.1 to 1.5 to 1.6, can i just go from 1.1 to 1.6 in one hit?
step 1: search the development forum for amon ra's recovery. read the instructions to flash it.
step 2: go to cyanogenmod.com and read the instructions for upgrading from scratch.
once you've done those two things, you'll be much happier.

You don't re-root when you need to change roms you just wipe in recovery mode
You need amon_ra
http://forum.xda-developers.com/showthread.php?p=4647751#post4647751
Like the other guys have said, upgrade to Amon_RA recovery. This allows you to flash updates from any filename, not just update.zip. The link is in my signature, or it's on the G1 Dev Forum in the sticky threads.
After that, boot into recovery and go to the Wipe section. Wipe all the things there, not just data. I never used to wipe everything either and I found that was the source of alot of my problems when changing ROMs. Obviously if you have your SD card partitioned and you choose to wipe your ext then you will lose what is on there.
Cyanogen has good instructions on his Wiki, but basically you want to flash DRC83_base_defanged, DO NOT reboot, and flash CM over the top straight away, then reboot your phone and you'll have a nice clean CM install.
This flashes the HTC Developer image which includes legal Google apps (Gmail, Maps, etc) and then flashes CM over the top which includes all his cool changes but does not delete the Google apps which we aren't supposed to distribute because it's illegal. Perhaps you are not aware, but Cyanogen got a Cease & Desist letter from Google, which is why we now do the defanged base method. More ROMs are moving to this method as time goes on, Pay's ROM and Super D are two which do this.
As an aside, I have found CM is not the fastest ROM. Some people have had better success with a ROM called Super D which is quite popular and includes many of the Eclair bits and pieces which CM does anyway. I personally use Dwang's ROM which is a much more plain Donut image however it absolutely flies. Both of these are linked in my sig, and are usually within the first few pages of the G1 Dev Forum anyway.
Thank you guys so much! I really appreciate how helpful the community has been. I've been having some issues with the the upgrading and maintaining because of my memory card slot dying out. A lot of the times the system will not register that I have my micro sd card in it or it'll say the sd card is blank. I just hope the phone lasts the extra 6 months till the end of my contract

I used to have this problem too, but it went away when I moved to 1.6 (coincidentally the same time I replaced the SD Card that came with my phone with a new Class 6 card). So either the upgrade of the OS or the SD Card fixed it.
In going to have to try the new men card cause the system is already at 1.6 but the phone is still trying to kill itself.

[Q] Questions from someone on the verge of Flashing (Cognition 3.02)

Hey all,
So I'm am effing fed UP with Samsung. My Captivate is a hardware powerhouse, and with the stock Eclair firmware and all their bloatware, it's laggy, bogged down, and just not the device I wish it was. And with the talks that the Galaxy S phones are virtually unbrickable, I have decided to seriously consider ROOTing my phone and flashing the Cognition 3.02 ROM. I have watched a lot of videos, done my research, but I still have a few lingering questions for those of you out there who have recently flashed this ROM, preferably for those of you that this is the first or near-first ROM you've flashed. I know how the process works, but some specifics are bugging me and holding me back.
Ok, so I've listed some of my major questions below. Feel free to answer some or all of them if you've got the time, or DM me if that's easier. lf I think of any other Qs I have I'll post them in subsequent replies.
1. First and foremost, what process did you use to root and flash cognition on your Captivate? I've been looking at the MobileTechVideos three part tutorial on youtube which most people seem to recommend. Is this what you used? Was it as easy as simply following the instructions word-for-word? Did you run into any problems along the way?
2. I know to use Titanium Backup to backup my apps and stuff, but I've read a lot of places that I should only use it to restore those apps, and not to backup and restore user data like settings and contacts. How did you do it? My major concerns are about my contacts/phone book, which I have synced to my google account, but I also have syncs to my facebook and twitter accounts, and my phonebook is nicely linked and everything across all three. I'm afraid to forfeit this organization, so I just want to know that I'll be able to get everything back the way it was without too much trouble. I know you can export your contacts to your SD cards, and I could presumably import them from their after flashing, but I just want to be clear on how that all works.
3. Do you use your phone as a digital music player? I do, and I use iSyncr to sync it to my iTunes. If you do as well, did flashing screw any of this up? Playlists, etc? Will I need to re-sync or will it all be there once the phone scans my external SD (which wont be wiped since I'll remove it beforehand)?
4. In your first few days of use, what are the biggest improvements you see in the Cognition ROM as far as daily use is concerned over the stock firmware? Any problems you've come across? What's the selling points here, in layman's terms.
5. Do you have any regrets about flashing?
Thanks guys, and any other advice you think would be helpful that wouldn't come under any of the questions would also be GREATLY appreciated.
4. No problems for me. Phone is smoother and faster now.
5. Not at all.

1. manually rooting is overrated. most, if not all, custom roms automatically root your phone for you, so there really is no need for you to do it yourself. except the first time: root your phone using the one click since it's simple, grab rom manager from the market and use it to download an update.zip containing clockworkmod recovery for the captivate and leave that update.zip on your phone and never change it or delete it. it makes flashing new roms so much easier and there is really no need to ever remove or change it. boot into recovery, reinstall packages twice, install zip from sd card, and pick your rom. also, you will never need to use rom manager again unless you lose that update.zip.
2. I use titanium backup in batch mode (hit the menu softkey and hit batch). click backup all user apps and system data, but uncheck everything that is in red text, therefore backing up only things in green text (useful system settings, contacts, calendar, messages, etc) and white text (user installed apps). then run batch operation. install new rom, use batch to restore all missing apps and system data. to re-backup newer settings, app data, or updated apps, use backup all new apps and newer versions, and then either redo old backups or forced redo of all backups.
3. yes, but I just copy and paste my music files over instead of syncing them. also your internal sd is never wiped unless you use master clear on odin, which I have never done, nor do i ever wish to, because in my opinion there is no reason to. therefore both your playlists and your music would not be wiped whether you put them on the internal or external sd. (unless of course, you decide to use master clear)
4 & 5. I agree with faroid.
Be sure you have the correct odin set up and recognizing your phone on your pc. Eventually you will need to use it for one reason or another. The most common is the odin3 one click jf6 but some newer builds cannot be flashed to firmware older than jh2.
1. To root i use one click root/ unroot vary simple plug in and press root then install clockwork recovery from the market its free with clockwork recovery you can flash your cognition

Did you use the full MobileTechVideos method when your phone got bricked? Or did you flash without reflashing to stock and wiping everything?

So how do I know which one I should use? Is it based on the ROM I flash, or my hardware (Captivate)?
Which odin stock firmware is based on the build (four digit number under battery such as 1006) and what version your phone came with when new, such as jf6 or jh7.

Do you by chance know which one I'd need off hand? I'm at work and don't feel like pulling my phone apart, but I can tell you that I bought my Captivate the day it came out, so presumably it came with the oldest firmware the Captivate ever came packaged with.
1. No need to root. That's an extra step you don't need. My method, get the update.zip for clockwork mod, just search the Dev section, no need to even install Rom Manager or anything. Take that update.zip and put it on the root of your internal SDcard (just the normal phone storage, not an external SD. Then using adb or button method reboot into recovery, choose reinstall packages. The phone reboots into stock recovery. Choose reinstall packages again and this time you get Clockwork. Wipe data, install zip from SD, choose zip file, pick Cog, install and done.
2. I use titanium for user apps only, ie, things I got from market. All my contacts are synced with google, so once I add my google info under accounts they are back. Sorry, i don't mess with facebook or twitter so i can't answer that. As far as settings, you just have to manually do that, ie, ringtones, wireless networks, etc.
3. Yes I do. And I also use iSyncr. No problems whatsoever. As long as you don't do a MasterClear. That option under Odin will wipe your internal SDcard also. The Wipe Data under Clockwork recovery just wipes out installed apps and settings but leaves your internal SD intact.
4. Honestly, it's just a much better experience overall. The phone is faster, smoother, and more responsive. Plus DG has taken the liberty of removing all the ATT crap and un-needed apps.
5. Not one.
My only advice would be to "be prepared". My sure you have button recovery available ahead of time. Check your Rev version of phone, ie, the date under the battery. It seems newer Revs require a different version of stock Odin One-click. Some people have had issues running the original One-click. If you have any doubts about your phones ability to go to download mode, in case you need to go back to stock, spend the $1 on building a USB Jig.
You will find that flashing is easy. Recovering from unexpected errors can be easy if you are prepared.

So do I not need to be rooted to use Ti-BU? I thought I saw that under the product description in the marketplace.
Also, under #1, when you say "Wipe Data" you are referring to an option in the Clockwork Recovery menu, not an Odin MasterClear, right? Will this wipe my internal SD?
If you got the phone on release you likely have a 1006 build with working 3 button recovery and can safely use the odin3 one click jf6.
Sent from my Liquid Metal using XDA App
TiBu needs root. I rooted using one click, then backed up user apps and data (used built in contact export to save contacts and smsbackup for texts).
Then I just ran the update.zip for CWR and flashed Cog - was my first flash too and pretty painless. TiBu returns your apps as if you never changed them.
Make sure you can access recovery and dl mode though.

Sorry, forgot you would want to backup before installing a new ROM. Yes, to use Tibu on your current ROM you will need root.
As for wipe data, yes it's a clockwork option. Like I said in #3 wipe data just removes user installed apps, and changes all settings to stock, but all data on your internal store will stay there, pics, music, etc.
Master Clear is the Odin option, which I never use by the way, that will completely delete everything on your internal SD, bye bye music, pics, etc.
This is all EXTREMELY helpful by the way.
Quick question about USB Jigs--is it easy to build one myself or should I splurge on the ~$15 one MobileTechVideos sells? There's seems pretty fancy, and I can't afford to be phoneless as I putz around trying to jimmy myself a jig.
I can't speak from experience but there's a thread here in QA that makes it seem easy. Just get 3 x 100kohm resistors, wire them in series, twist it to look like a horseshoe, there you go. If you have a radioshack or other electronics store near you it's worth a shot. Like I said, I think all 3 resistors cost may $1 total. You can also test it on your phone to make sure. Touch the jig to the 2 leads, if it goes into download mode instantly you did it right. Pull battery and reboot and all is well.

Yeah I saw that thread, I'll have to try my hand at it before I do this process. Better safe than sorry. Thanks.
Ok, so, the plan = build working jig and DL proper Odin just in case, one-click root, Ti-BU, move clockwork update.zip and cognition zips to my root folder, reboot in recovery, reinstall packages/flash clockwork, then wipe and flash cognition. This sound correct?
That sounds about right. Really the only thing different i do is on the root of my storage I create folders for ROMs. So I have a Cog folder with the rom in it. Once you have Clockwork installed and you are choosing to flash, it will let you navigate to different folders. That's just my preference because I don't like to have too many individual files on my SD. Minor thing, just thought I would mention it.

Haha, appreciate the advice; I like a little organization in my life as well.
Sounds like you've flashed a few different ROMs. Have you ever bricked your phone to the point where you needed a jig? Or has it always been smooth sailing?
I guess I'm just trying to figure out why one person's phone would brick and anothers wouldnt. It kind of makes me assume that if you brick your phone, you've done something wrong, and if you just do the process right, everything should go smoothly. But maybe that's naive of me.

[Q] Going to root wife's nook, what do you suggest?

So we just bought a nook color and she is still new to it. Obviously, she reads lots of books and I... well, want to make this into a tab and play w/ it. She might want to do web browsing and install some games/apps, but primarily will be used as an e-reader.
What rom (if any) do you suggest I flash? Or will I be better off just rooting the device and leaving it as is (w/ market)? She has no patience for developmental stuff so looking for something stable but also something I can play with

Root the Stock and leave it. its the most stable rom.
Make your own SD card, running Nookie Froyo or CyanogenMod. When you take the card out and reboot, her machine is completely back to normal, or so I'm told. You both get to have what you want.
I can run CM from SD card w/o rooting the device!? if so... sweet, I saw sum tuts but still educating myself. Rooting and leaving stock is also a good idea, however I heard B&N is able to update your device thus losing root... Is this true?
For her, it sounds like just rooting would be the best option, since it has the market, all of the B&N features, and is stable. As mentioned above, running a ROM from the sd card is a good option for you. After rooting it, you could format the sd card used to root, and then load a ROM such as CM7, Froyo, or Honeycomb from the SD card to play with.
This way, she has her mostly stock setup, and you have your tablet setup that you can load by just popping in the sd card and rebooting. When you're done playing with it, power down, pop the sd card out, reboot, and it's back to her setup.
If you do decide to run a ROM from the sd card, make sure to get at least a class 4 (sandisk class 4 4GB works well for me). Then, if you find something that would work for both of you, you could look at flashing to internal EMMC for better speed/performance. Another option is dual-booting between ROMs, which you can find more about in the development section.

There is a thread in the dev section on how to block the updates. Here's a link to the sd card version of CM7 you asked about. You don't have to root first, but you can.

As suggested I'd root the stock software for the wife, and when you want to play choose a ROM that can run from the sdcard and you will be good to go.
Currently I run 4 different setups. Stock rooted on internal mem. Then I setup 3 different sdcards to mess around with Honeycomb, CM7, and Froyo from time to time.

You do not have to root it first. All you have to do is create a live SDcard with Clockwork ROM manager put the SDCard in and boot it up holding the n and the power button in > wipe > flash CM7.
With this device reading off the SD first you do not have "antonoot" first.
I've ran CM7, Honeycomb and a few others. My personal choice is stock rooted device is perfect.

She gonna be using it 75% of the time, so I decided to root and leave it as is. Everything works good. I tried to do nookie froyo off SD card but had too much trouble w/ adb, i'll save it for another week. But for now, stock root works good. Got Zeam and Home switcher to help both of us out
I wanted to point out the only downside of rooted stock is that she cannot use in the in-store B&N features! If she plans on using that (i've heard they have not only the hour of reading free, but also sometimes offer deals and events) then you might wanna not be rooted and use the SD card. I know this is a little late to tell you as you already did it, but I thought I'd let you know anyway.

I'll throw this in for whenever you feel like creating a bootable SD CARD to play with. I've found that higher class sd cards make a much bigger difference in how fast/well the rom operates than you might think.

[Q] Nook Root

Hello,
I have read and watched and searched different ways on rooting the nook and they all either don't seem to work or are confusing. Can someone point me in the direction of complete step by step instructions for rooting my nook on a micro SD card. I feel dumb while trying to do this because its my first ever root even though I have assembled computers. Its the software that makes me nervous. Thanks for any advice.
I totally understand how you might be hesitant to jump in. I came here a few months ago from a windows phone and had no clue about Android devices. Get yourself a Sandisk card (4 or 8gb ought to do the trick). I went with a cheaper card at first and was very disappointed with the way it worked.
Follow the directions here:
http://forum.xda-developers.com/showthread.php?t=1000957
and you should be fine. good luck!
It may be a little daunting at first (I'm a new NC owner myself). But just keep in mind, the NC is setup to boot off the SD Card first. So you essentially always have a recovery method there. Also, if you don't flash CWM (Clockwork Mod) to be your recovery, you can always use some methods to restore the device ( 8 failed boots for example). The methods are listed on the forums quite a few times. But, basically... android is just another flavor of *nix. Though it does have its own intricacies.
As long as you backup your current setup through CWM's backup operation (AKA: nandroid). You can do pretty much anything and just do a restore to get back to where you started. It's almost like ghosting a computer... It just doesn't redo your partitions.
Get yourself a copy of CWM Here's the most recent 1gb image. This basically gives you a bootable SD Card that can backup/restore the internal memory, format it, and flash images.
You can get the latest cyanogemod rom's nightlies here. You also need Google Apps if you're going to flash the new rom though.
And here's a guide to revert to stock.
Personally, I wouldn't bother with the SD Card system... I would just root the internal rom and flash back if you don't like it.... or flash a different rom, like CM7, if you want the nook to be more of a tablet than an e-reader... just keep in mind... it wasn't meant to be a tablet...
Hopefully this helped.
Ya just wanted to chime in. Its pretty hard to mess up on the process of rooting and if you do there's ton of threads to help you out along the way! Even the NC wasn't meant to be a true android tablet it does the job well and well worth the money. Maybe ill go better later down the road, but after what I paid for this NC brand new on CL I SOOOOO happy!

[Q] Getting back to the original....

Hi all.
First of all let me use this opportunity to thank this amazing and always growing community for their help and everything else in my Android life.
Well, I have been using different ROM's recently and experimenting a lot with my device. Its been great.
To cut it short, I am looking to get my device back to it's original state.
I have a Samsung Galaxy Mini S5570, rooted, with MusicRom.
I also have a 2GB SD card, which I 'separated' in order to install apps on SD.
I would like to know how can I get the SD card back to the original mode, flash a simple Android 2.3.6 rom, and unroot it.
Help is appreciated.
You can remove the partition using a partition tool like multitool wizard. You can flash gingerbread through Odin, a good tutorial can be found here: http://youtube.com/watch?v=tcki_b7j0bQ. Stock roms are unrooted by default. Click thanks if I helped.

Both helped a lot.
I found out that the tool is named Mini Tool not Multi Tool.
I am trying to un partition my SD card now. Than I will try and flash the rom through Odin and I am all set.
Thank you both.
Just a simpler method than that one:Just move all files from SD card to your PC.After emptying SD card go to Settings >Storage>Erase SD card. Now your SD card is 1.84GB free
