[Q][GT-i9020a] How do I reflash back to factory?

Hi, new Android user here.
I was trying to root my Nexus S phone yesterday and I'm having problems. There is a lot of rooting guides out there and I used one from xda and also one from unlockr.com. Managed to root the phone ok (I think), but everytime I flash a custom ROM, the phone won't start at all, it just sits at the boot up screen and repeats itself.
So I'm thinking, I should just start over again. So I flash the stock ROM from xda back to 2.3.1. Everything seems ok, the phone starts up... but it's always stuck on airplane mode and the phone itself doesn't even show stuff like IMEI, mac address anymore.
So now I figure I've probably messed the phone up enough and need help lol. How do I go about reflashing the stock ROM and getting my Nexus back to out of the box condition (Stock ROM and no custom bootloader)?? Any guides or step by step instructions would be very helpful.
Thanks

Did you wipe before flashing roms?

Maybe flashing the KB2 modem would help that but the 9020a came stock with 2.3.3 and not 2.3.1 so that could be it...I'm not sure but that software wasn't meant at all for ours so it could be part of the problem. But if I was you I'd take a look at this thread wich has all the stock software for your phone. Make sure you wipe everything in clockework and then flash the stock rom. http://forum.xda-developers.com/showpost.php?p=13123996&postcount=39
dsixda uploaded the stock backup and the stock recovery, you can read more at that link, good luck hope it helps

You can download the full stock ROM from the link below:

Move the zip file to sdcard. Boot into recovery and flash the ROM. It should get you back to stock 2.3.4 ROM, all locked.

[Q] CM7 / ICS Flashing issues

I soft bricked my phone playing with ICS, I got a JIG and solved the problem
I can now ODIN back to any version and once rooted I can install any samsung based rom, the problem comes when I try to flash aosp both CM7 and any ICS beta
What happens is I select the zip, it runs a script and the phone reboots, I see the AT&T logo and then it mounts the sd card, it says it can't find the zip file.
I've tried Froyo, Eclair, even gingerbread (I know your not supposed to flash cm7 from gingerbread, I'm just running outta ideas) I have froyo bootloaders, I reinstalled them with heimdal. I've also done a master clear and erased the internal sd card
Does anyone have an idea of why this is happening?

Are you trying to install the zip from ClockworkMod?

Most likely, the rom is incompatible with the flash method you are choosing which bricks your phone. I had this happen to me twice from either flashing a rom the wrong way or just trying to flash the wrong rom all together and killing my system, but I ended up telling AT&T Techs that it happened when I tried upgrading to 2.2 to avoid warranty issues and they replaced my whole device with a refurbished unit =]
However keep in mind that they cannot jig your device and you will have to do that yourself to get your data off your device before you try getting a new one via this method.
Possible Solution:
1. If you can, flash cm7 to your device
2. Flash This ICS rom

If you have already tried this then I apologize, but I hope this helps.

Another problem
Ok, everything I see says I should flash from a captivatemtd recovery, but when I install Rom manager and select captivatemtd, it says their are no offical recoveries for it, I'm currently running cognition froyo 2.2 with froyo bootloaders
Does anyone know where I can manually get the captivatemtd CWM? and how do I install it?

I'll go over my method of installing(I've had ZERO issues flashing from/to any ROM)
1. I FTS/MC using Odin 1 Click. My phone build is 1008
2. Root with 1 click root(I have to do steps 2 and 3 because I do not have 3 button recovery)
3. Sideload and install ROM Manager(Rom manager, and CWM update.zip are in the Sideload zip that's attached)
4. Copy CWM Update.zip and ROM to device. Reboot and install CWM
5. Reboot into recovery and install ROM
Odin 1 Click(If you can use it)
http://dl.dropbox.com/u/12100225/Odin I897UCJF6-final-OCD-REV0.zip
Root 1 Click
http://dl.dropbox.com/u/12100225/Root.zip
Sideload Wonder Machine and ROM Manager
http://dl.dropbox.com/u/12100225/Sideloading.zip
Edit** What is the build number of your phone?

Here's what you need
Just download this rom
http://download.cyanogenmod.com/get/cm_captivatemtd_full-181.zip
And then watch this video!

Flash CM7 using odin
then flash ICS using clockwork mod using the instructions I gave you before.
That's the easiest way I found to do it and that's how I went from stock rom to CM7 rom and then finally to ICS

Tried this to the letter still doesn't work, could it be because of rom manager not finding a recovery for captivatemtd, some pages say I need that recovery but it isn't available in rom manager.

Finnally
Finnally got CM7 installed the problem was I had to do the three button boot into recovery twice, the first time updates clockworkmod to version 5.x
Now to try ICS again, wish me luck

Thanks
Thanks for all the suggestions, the tip in the video about flashing the speedmod kernel did help I think, I've successfully flashed
teamhacksung's ICS Port for Captivate (BUILD 9) again.

A couple notes here:
1 when your flashing cm7 from cwm( NOT 3e RECOVERY THOUGH) you need to flash the. Zip file, then reboot system, IT WILL PROBABLY BOOT LOOP, three button back to recovery and flash again, then while in recovery still flash gapps. Reboot and it will install fine. You should ONLY need to do the two time flash the first time going to cm7.
2. When you go to rom manager and choose manual flash overide from hitting the menu button you will get the unsupported recovery, DON'T WORRY about it and hit ok. Then another popup will come up and choose 3.x and it will work.

[Q] ics rom upgrade infuse 4g help

So Im a new member to the site for the most part (have been reviewing threads for more than a year now, though) and decided to finally sign up while trying to flash CM9 ICS on my infuse. Im running into issues. I currently am running ZUES Build 6, with the ICS theme / framework. I LOVED CM7 for the Ascend, so decided to give it (CM) a try on my infuse. The Dev threads say that i should have no issues b/c Im flashing from a UCBL3 / GB ROM, but when i try to just flash it, its an invalid package...? I tried flashing over the ICS recovery from both Hiemdall and Odin but hiemdall needs a "valid tar.gz" and i also encountered the same type of issues with Odin. Ive used Odin before to flash to stock, but im a complete noob to Hiemdall. Any help from an experienced Dev or another flashoholic is greatly appreciated! dont have 10 posts to ask in the Dev section yet...

Could you be trying to flash a .zip file that is designed to be flashed in CWM recovery via Heimdall or Odin? I don't have an Infuse but I'm currently running AOKP on my Galaxy SII and the files posted by in that development thread are CWM flashable.

ive tried in all 3...cwm says
"Cant open /sdcard/update-cm-9.0.0-RCO-infused4g-04152012-UNOFFICIAL-signed.zip
(bad)
installation aborted"
I figured it was a bad DL...tried 2 other DLs, no luck
they said to flash from gb to flash a file called ICSRecovery.tar.... how would i go about doing this...i have red cwm like needed. im completely lost here...And thanks for replying.
edit: here are the pages, and is your rom ICS

I does sound like a bad download, redownloading would have been my first instinct as well.
Rereading your post, it seems like maybe you haven't been able to successfully flash the ICSRecovery.tar that jt1134 mentioned in the first link you posted. Entropy512 doesn't mention needing to flash that recovery before the .zip but it may be implied, I haven't read nearly enough of the pertinent threads. You should be able to flash the .tar using Mobile Odin.
It looks like you pulled the download from Entropy's thread here
http://forum.xda-developers.com/showthread.php?t=1601844
Entropy left some pretty detailed instructions that should be easy enough to follow after you've overcome this initial hurdle.

so you suppose i install mobile odin...will try, and will keep progress updates
update:mobile odin not available for my device...must dump... :/ 30 minutes...............
Update: i was able to flash the recovery image for ICS through sgs kernal flasher, reboot, and get rainbow recovery. it WAS a bad DL, the ICS recovery couldnt flash it...but when i tried to reboot normal, i got into what i call IRONY!!! i was stuck in a recovery loop ( you see the irony in that, right?). reboot put me back in recovery again every time i clicked the option...i was able to get out of the recovery loop by flashing the zues 6 rom (because the ICS couldnt read the boot image of my backup) then from there i rebooted and got the voodoo recovery (huge relief). I was then able to restore my backup (after practically drenching myself in sweat)! I will be uploading an image of the rainbow recovery, as its been dubbed, for those who would like to see what a pain in the ass it is.........

Twrp boot loop

This happened before but I can't remember how I fixed it.
1. Flashed TWRP (over codename if that helps)
2. it bootlooped back to recovery instead of starting the system
3. tried flashing another rom/ didn't work
4. finished season 2 of the walking dead
5. reflashed TWRP didn't help (TWRP flashing failed even tho it was the same file I used to get TWRP in the first place)
6. Took the battery out but that didn't help either
I really don't want to odin or use one click any ideas??

Meh, lets start with the first two...
To stop the reboot to recovery, you must flash eollie's oneclick with bootloaders (so flash it twice, second time flash bootloaders) and go back to mtd.

I got it from what I thought was the official XDA TWRP thread but I'm not sure if it was official or not
at first I tried reinstalling codename but now I'm trying Beam (Tuk edition) and it seems to be working

TWRP Major Boot Loop
hey guys, im new here and i desperately need help with my phone!
the other day i was flashing a rom on my samsung galaxy s 4g. Things were turning out fine, until i had some complications on my phone.. so, i removed the rom. when i rebooted my phone, it went directly into the team win recovery project boot loop and every time i try to reboot my phone, it goes into the twrp. I also can't wipe anything and i can't delete anything! Does anybody know how I can solve this or is my phone basically bricked

more details would be helpful..
As in what rom, or what kernel.... etc... and make sure you have the corret phone.

Same problem with t959p
Looks like I'm not alone.......here's my story
the other day I wanted to switch from a stock rom to a custom, so I flashed redux 1.3 which was actually a froyo rom, and it started draining my batt like crazy so I flashed another rom on top of the froyo rom not realizing what I was doing and somehow messed it up cuz now it will only boot into recovery.
Now just to be clear I know this was my fault, I know I should have odin'd back to stock first, but I wasn't thinking at the time.....Ohh and just so you know I've flashed this sucker hundreds of times and was always able to get out of any mess I got in.
So here is the situation as it stands now, 3 button combo to enter download does not work. I can only get it into download with the jig I made. the problem is even in download mode none of my pc's will detect the device as a Samsung composite device, so odin will not see it. I've installed every possible 32 n 64 bit driver I could find including reinstalling kies. Kies wont even see it. I've tried flashing a few roms that I know worked and still it just boots into recovery. Now one thing I'll tell you is that depending on which rom I flash I can get recovery to switch from cwm to twrp. right now I left it with cwm 6.x.
what I need is a cwm flashable stock telus t959p rom complete with bootloaders or at the very least a cwm flashable zip file containing the bootloaders to see if I can recover the phone.
ohh and if your thinking about telling me to google search for the answer then don't bother.......I've spent the last 4 days reading posts and going to different websites and repositories trying to find something that would help me and so far nothing has.
the only thing that might work as a last resort is pushing the bootloaders as per one of raver's or whitehawks posts but it's a little more complicated for me as I would have to set up a laptop with Linux as I don't think i'll be able to pull it off with any of my windows pc's, win7 and win 8 only.
so if anyone has the files I need or can make them please let me know....or if you think you have another solution I could try i'm all ears err eyes.
thanks

Have you tried heimdall one-clicks? Maybe it's showing up as gadget or something like that. I've had luck using zadig and heimdall to bring it back from the brink of death.

Nothing to see here, move along

Would like to revive a slightly dead thread.
I upgraded to a Galaxy S3 and no longer use my SGS4G for daily use. I had AOKP and disliked it, FC's and didn't like the feel. I have been trying to install a new rom ( old rom, VH Black Ed. ). Every time It loads into TWRP I have the ability to select the zip, install, it says complete, but reboots right back to TWRP menu. I've tried flashing CWM and it will install, flash the rom, reboot, and right back to this TWRP B.S... what am I doing wrong? I want to continue to use this SGS4g for music and internet duties.
How can I install CWM and have it stay even after a reboot? This TWRP is starting to me off

Did you happen to one click to stock before you went ham at the recovery?

K1 stuck on Nvidia Logo

HI all
i was using my recalled tablet normally alongside with the other and at some point i decided to put on a custom rom.
Before this a friend of mine unlocked the bootloader , rooted the tablet and putted on it the CWM , flashing the nomoreota.zip
After a long period without any problems i decided to go on custom trying to flash the Blisspop first, then Dirty Unicorn and then another one i don 't remember.
The result was the same with every single one : black screen and nvidia logo and that was it.
I successfully flashed TWRP adn used it to install the roms but there was no different response.
Can anyone please help me ?
i wouldn t mind to go back on stock but i fear to brick my tablet due to the kill switch, so i prefer to go on custom to be invisible to nvidia servers.
Thank you for your help in advance

Any Ideas ?

If you change from a 5.x to a 6.x ROM, you need to flash the correct blob as detailed in the follwing thread
http://forum.xda-developers.com/shield-tablet/general/unofficial-update-original-shield-t3281541
You also need to install a 3.x.x TWRP.
If you still get into recovery and are able to flash roms, this is pretty much the only possible problem I know of.
