[Q] PLEASE HELP!!! Cannot Boot Nexus S!!

Hi everyone,
I'm sorry I'm quite new to this, and I'm afraid I've gotten myself somewhat stuck with my Nexus S. Yesterday I managed to root it, install superuser, as well as clockwork mod. Today I wanted to try a new rom and after some attempts, it seems I no longer have any working roms on my phone. After much searching with no luck, I turn to you guys for your expertise.
So I am able to see fast boot upon pressing the volume up and power buttons, and am certainly able to choose recovery and get into clockwork mod. Within clockwork mod I can mount USB storage, so I can transfer roms to the internal SD card. I've tried 3 or 4 roms, some say they install correctly, others not, and after trying to boot after any installation I simply get stuck at the google screen with the lock image at the bottom. The only things I have "deleted" is wiped the data and cache. I have no idea, but I think I may have erased the bootloader image or something else that I should not have that is required.
I have a i9020a model (non-4g model I believe), can you pleeeeeeeeeeeeeaaaassee help me!! I just want to get back to gingerbread 2.3.6, and my phone back up and running the way it was. I've become quite nervous after some searching with some saying a resistor mod is needed on the hardware!!

Your okay cause you can get into fastboot and recovery so don't worry. Maybe the rom you downloaded is not for your phone. Did you make a nandroid backup before flashing the rom? If yes then go into backup and restore from clockwork recovery to go back to stock.

If you can get to recovery, just flash the stock image FOR YOUR PHONE. Then you can go through and reroot..don't worry, you'll get the hang of it.

So my phone is not "bricked" as they say?? I'm not in big trouble?
I did not make a nandroid backup What kind of image am I looking for and how do I install it on the phone? I know my phone is of the variant i9020a, but how am unsure of how much more specific I should be looking for.
Looking at the following post: http://forum.xda-developers.com/showthread.php?t=1063664.
Should I try installing the Android 2.3.6/GRK39F/UCKF1 Radio/KA3 Bootloader option?

Choose the latest 9020a version of the FULL ROM, which is what you have already have eyes on.

I've tried installing the file I mentioned above, but I get a status 7 error when trying to install, and the install is aborted.
Could I get some more assistance please? Can anyone point me to a correct, full rom? Or perhaps I'm installing it incorrectly, could someone be so kind to outline the correct steps to a proper install?
Edit: I think the above mentioned file is for a GSM model, I'm sure I have the CDMA version.
Also, somewhat good news. I managed to install the oxygen rom, but for the 4g version and installed fine with no errors, but I have no service. What does this indicate, as I still want to restore back to a factory version (non-4g) of gingerbread 2.3.6.

What CWM version do you have? Is it 3.0.0.0?
Also, if you have no service, it's likely that you downloaded a ROM with an incorrect radio.
Edit:
If you have CWM 3.0.0.0, make sure to download the latest version, found in this thread: http://forum.xda-developers.com/showthread.php?t=988686 (use 5023-cyan.img). You flash this the same way you did CWM previously, though in the terminal make sure you type out the 5023-cyan.img file name.
Next, download the stock ROM from this thread: http://forum.xda-developers.com/showthread.php?t=1063664. Simply look for your phone version, and you'll find the correct software variant.
Maybe you've fixed your phone already; if not, I hope this helps!
I wish you the best of luck. Oh, and through problems like these, you come to learn a lot more about your phone. That's what I've found, at least.

At the thread you mentioned above there is a version with a different radio, you might want to give that one a try.
You also said that you only wiped data and cache, so maybe you should do a full wipe before. Not doing that can sometimes lead to problems.

To be brief, the phone is up and running as brand new! Thank you so very much everyone. It seems the error was with CWM, as I was able to install and boot a 4g oxygen rom on my phone, I went into rom manager, and at the bottom of the list was an option to upgrade to 5.x. Installed the CWM update, wiped everything and was able to install the factory rom, no issues, and everything works just as I remember
I have most certainly learned more about my phone, and I am going to look at it as a rather stressful learning experience rather than a mistake on my part.
But a sincere thanks to everyone once again, I posted this at like 4am here and had a response within a few minutes, I was pulling my hair out haha!

Flashing to stock rom will help you out. You can get stock roms from Internet simply by searching in Google...

[Q] Can't Connect to Wifi

I searched around and couldn't find a definitive answer. The problem I'm having is connecting to wifi at all.
After getting a phone replacement, I unlocked the bootloader, flashed CWM recovery, rooted, flashed CM 10 nightly 09/29 and GApps but when I booted, I could not connect to wifi at all...I can't even turn on wifi because the toggle is greyed out. I have tried reflashing several times and even tried a different rom. but still no luck. Anyone else have this problem or know how I can fix it? I rely heavily on wifi because of ****ty data in my dorm. Any help would be much appreciated!

Hello,
What was the version of software on you phone before rooting, was it a T-Mobile phone? The newest version for T-Mobile has created is issues for roms that aren't the same version.

Yep, just found out that was the issue. kinda sucks because I'd rather have jelly bean! Oh well guess I'll deal with no wifi till a fix comes out.

why does the Ruu not work anymore i want to take my phone back to where the wifi works..... i have a cwm backup from before the update but that did not even fix the problem
____EDIT____
Well i got the wifi back. ( and the OTA update ? again )
Relocked the phone boot loader
I opened the RUU
took the Rom.zip from the folder.
took the stock recovery img
flashed the stock recovery img
start the phone back up
downloaded the update again. ( 4.0.4 )
did all the waiting etc
phone powers down reboots applies the updates to it self.
powers back up updating completed
WIFI WORKING.
go to try and do the ruu.exe again but no it says error 140( i think ) wrong bootloader version.
This update changes the bootloader to version 1.14___ So now the phone is non tamperd and says relocked so back to stock ( YAY )(((for now))))( i think lol )
Most importantly the Wifi is working.
If anyone wants i can take and give the files from the RUU ( not the whole zip but what ever img's you want from it ) Just send me a PM i will mail it to ya.

So did you use the 1.84 ruu? And you did this after applying the tmobile ota?

[Q] Flashing to stock - phone force closes process com.android.phone, help

Please bare with me since this is the first time having to post for an issue since I usually find an answer on your forums
So here's the situation.
I bought the photon q 4g lte from ebay and it came with the unlocked bootloader.
Needless to say it was with the stock ics and i tried to find a jellybean update because it wasn't taking the ota and ended up going with cyanogen since i had no problems before. However those phones i had before were with sim cards not cdma.
I found out i couldn't update prl or profile manually without having to do something on the pc.
So after searching left and right i found i could use rsl lite (I used 6.1.5) and eventually found the "stock" file from this post
http://forum.xda-developers.com/showthread.php?t=2095536&highlight=rsd+lite
I did the stock jellybean, got it to go through the process and it booted up with no errors.
However, when it boots into the os it pops up a force close on omadmclient_sprint_dataservice and eventually also on the process com.android.phone.
I tried putting it in airplane mode to see if the service error would go away but it didn't work for the process part crashing.
I tried re-flashing, deleting cache in recovery, doing a data/factory reset in recovery and the one time i was able to do a data factory reset within the settings menu.
I could not find anyone that said they had a rom that worked with sprint and updating prl within the rom, if anyone knows of one let me know and i will flash it through rsd.
Otherwise does anyone have an idea of what could be happening because googling the omadmclient part did not pull up anything specific and pulling up the process issue for other phones has not helped me either.

Was this a hacked GSM phone, or are you using it as CDMA?
I've never heard of people having FC issues after flashing a FXZ from RSD. Which one did you flash? Android 4.1.2 - Sprint US - 9.8.2Q-122_XT897_FFW-5 (No simlock) ?
If you are on stock, you should be able to update the PRL within the ROM.

I was trying to use it with cdma network through sprint. and yeah that was the file i downloaded, had to remove the getvar to get it working but flashed with no errors after doing that.
As for updating the prl i can barely navigate through the phone, there is no home page loading and the process pop comes up often enough that its hard to go through the settings

Sounds like something went wrong mate. Are you already activated on Sprint? I don't know if that would matter, it might.
I would honestly redownload and redo the RSD process.

I originally tried to activate the phone through cyanogen and then when the rep said he couldnt do it because of the lack of prl to update within the rom we just setup the activation back on the old phone/ That phone is working on the network.
I re-downloaded the file just in case and re-flashed but same problem. The only thing i thought of was maybe updating the radio but since its a stock rom it should work out of the gate. whats also weird is i tried turning wifi on but it didnt work either.
Anychange you know of a rom that works with sprint. I dont care if its stock since i would probably root later again.

Which one are you flashing?
Try another perhaps...? I honestly have never heard of this. It sounds like the phone might be damaged, or the RSD process just did not flash correctly.
I guess I should ask, was the phone modified at all for the GSM SIM slot mod? I wonder if having a non-Sprint SIM in is messing with it... That is just a shot in the dark.

so far the only rom i tried was 10.1 cyanogen and the stock rom for jellybean. However for the stock rom it doesnt let me downgrade to ics with rsd 6.1.5 do you think if i downloaded an old version i could downgrade to a lower stock rom?
Also I honestly had not looked for the cdma roms since most of what i saw was troubleshooting related for this phone but i just saw this rom -AOKP 4.2.2 (Android Open Kang Project) (CDMA&GSM) that you created - http://forum.xda-developers.com/showthread.php?t=2293892
I re-rooted and installed that one and it looks great, just wondered how you got sprint to activate the phone or if you had done it before changing the rom? Also how would the prl and profile be updated.
Lastly the wifi wasn't turning on this time either, it did work initially when i got the phone so that has me stumped.

To downgrade to ICS, you need to remove some additional lines. See this post for more information on that.
However, you should be able to update the PRL on either stock ROM.
I think I said this before, but I will say it again. You need to do PRL updates, activate the phone, and get EVERYTHING working on stock BEFORE you flash ANY custom ROM. This is just standard practice - you don't want to put the cart before the horse! Get the phone working, then play with custom ROM's.

[Q] no signal...any help appreciated

picked up a used m8. Which had cm11 pre installed (fine with me it's what I'm used to running on my old galaxy nexus) just picked up a new sim card today and put the new sim in and it should be active but it wont pick up any vzw service (no bars just the empty triangle like shape) Any thoughts on how to get it to pick up signal?
When I hold vol down and power on I can see the following
CID - VZW__001
HBOOT - 3.16.0.0000
RADIO - .89.20.0321
OS 1.55.605.2
Appears to have the new radios and software.....
Normally, I would just restore the backup but there was no back up on the phone.
My first thought is to try flashing the most recent radios to see if that's it, but can this be done through .zip file in cwm or twrp? Or must they be flashed via fastboot?
Second thought is to reflash the stock 4.4.2 ruu then do factory reset.
Third thought....Is there anything else that I can do?
I wanted to get input from those who are more knowledgeable than myself on what would be the best method for proceeding..
Thanks

The info you posted isn't the new radios or the new firmware. Try flashing the 4.4.3 firmware from my firmware thread..update that an see what happens. You can find my firmware thread in Vzw m8 development.

OK I'll give that a try and report back

Ok I followed the directions and now I get signal in the triangle and an LTE connection. (Thank you Tigerstown much appreciated)
Now, When I hold vol down and power on I can see the following
CID - VZW__001
HBOOT - 3.18.0.0000
RADIO - 1.09.20.0702
OS - 2.21.605.2
but when I go to place a call it says "Mobile network not available"
After CM boots When I go into Settings > then about phone> then status everything looks normal shows verizon wireless under network but a few lines below under Service State is says "voice: Out of service, data: in service"???
Any ideas on what else I should do to get it to be able to make phone calls? Should I try flashing the radios via fastboot? Since I just used the sdcard method mentioned in your post instead of the fastboot method to update?
and strangely enough also under status a few lines below that it shows Mobile network state of connected.
feel like I'm close, just missing something.....Anyone more knowledgeable than myself have any ideas to get it to be able to make calls?
Thanks

So I downloaded VZW stock pre-rooted rom and as soon as I booted up everything started working as it should. Didn't even get to removing sd or re-flash stock recovery or factory reset. I might do that eventually as I do want to go back to CM or maybe viper rom. But I def. wanted to report back and say thank you for your help! I really appreciated it!

[RESOLVED] SIM unlock?

I am traveling to Europe soon and would like to SIM-unlock my phone.
I have the unlock code, but since I am currently on Fulmics 5.3, the unlock code doesn't work.
I think I need to get back to some stock-based rom.
My issue is, I am having trouble finding such a rom, and I am afraid to brick the device that's working fine right now.
Could someone please point me to a stock-based rom which would allow me to SIM-unlock?
Should I just install this ROM?
http://forum.xda-developers.com/att-lg-g3/development/rom-lg-d850-20f-lollipop-5-0-1-extras-t3052041
Kind of scared of going back to Lollipop from a MM-based rom.
Thanks in advance.
Edit: Went with installing the ROM linked above. Went smooth. SIM unlock also went smooth. Currently restoring nandroid backup, hope this works out as it should.
Edit2: All is well.
