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.

that did the trick. thanks everyone, now time to try rooting and flashing ROM again!
hrm lol now trying to update it to 2.3.4, it downloaded the update, but on reboot i get the white triangle with ! in it :\
this phone is so messed now
edit: well now everything is ok again, wiped data, flashed with CM7 and now it says 2.3.4, go figure.
I decided to give the new CM9 rom a try this morning on my verizon s3. after playing around a little i decided that I liked the stock rooted rom I had before so I was going to return to my nandroid backup. However, CM9 has its own recovery. I flashed my other recover, which was InvisibleK's recovery, which actually boots into a stock rom from recovery but never really goes into the recovery menu. So now I am stuck bootlooping because I think the recovery is trying to boot up but isnt finding the rom becuase I couldnt flash it from the CWM rcover that I was on with CM9. I can get into download mode but of course Odin is not seeing my phone for some reason. Anyone out there have anysuggestions? or did I just make myself a fancy new paperweight?
got odin
i got to odin now. i recognized my phone. I switched usb cords to the one that came with the phone
flashed stock rooted rom no luck
flashed stock rooted rom thought i was in the clear and now its bootlooping at the verizon boot animation. Im pretty sure i just have to factory reset but i cant get into recovery

Revert to complete stock with no root, then try to access the samsung recovery and do a factory reset from there.
unrooting brought me back to stock recovery
I finally sbf'ed back to the stock rom and being unrooted must have not allowed the phone to use the recovery I had installed and instead took me to the stock recovery where i was able to factory reset and all is good now. Phew..... that was a close one
thanks skander
Thank you very much. I actually tried that last night. I was getting desperate. wasnt sure if it would work or not but I thought maybe that and if that didnt work i would try flashing a different recovery from adb but i can never get adb to work from my pc. Anyway though, didnt matter. its all good now. Just got root back and learned a valuable lesson. thanks again....

No need for all caps, bro, makes it harder for people to read.
Do you have a nandroid backup from before all this happened or something ?

Hey everyone,
My little brother is trying to learn more things about mobile devices and wanted to have a go at my old piece of junk, stock optimus one p500h. So i let him have a go and now it's not working so here is the problem.
First he rooted it and that worked fine with gingeroot and then proceeded to install romanager which bricked the phone but he was able to recover the phone with a recovery.img and using LGMDP-v1.5 and emergency mode.
After that he installed some android system recovery thing "RA-thunderg-1.2.0-gnn" not sure what the software was originally, regardless he tried flashing from the flash from zip from sdcard and used a cyanogenmod zip which he said worked and then the phone said success and rebooted.
Now the phone just sits at the cyanogenmod loading screen and will not boot.
I am able to get into the recovery menu with home,down and power and emergency mode also works.
Where did he go wrong and what does he need to do in order to get this to work properly? Thanks for your help everyone and sorry if the post is a bit disjointed i'm trying to translate what he's saying into the post xD

If running a Windows PC and the device can boot in to fastboot, you can use Android Flash Recovery ( link in my signature ) to flash another recovery image. There are some more complicated ways using ADB, but well try to avoid them ATM You can also use LGMDP to flash a different recovery image. There are several floating around here at XDA.
As for where he went wrong, I cannot say. Piece of advice, if in doubt - don't do it.
Have you tried booting to recovery and wiping cache and dalvik cache then attempt to boot to Andorid?

thanks for the fast reply, looks like recovery is gone now? I had attempted to clear the cache though. Would you mind giving me a step by step as im unsure of what i need to do now xD not sure what i need downloaded or to do what with what after my brothers done all this haha
Just flash a recovery from LGMDP for your phone.. then download a rom for your phone and wipe everything in recovery and flash the rom
And do not flash stock rom from kdz or lgmdp if you cannot boot your phone. It has high chances of bricking

ok now it's running again and sadly it's giving me an unkown baseband and no service now! I tried flashing to the old legacy baseband for cyanogenmod 7.2 / 2.3.7

Cm7(except a very old one from mik_os), stock gb and up requires new baseband. You can search for baseband fix and install through recovery ( I don't remember if it's old bb fix or new bb fix, try for yourself )
You can also search how to install new bb permanently but it's more difficult and has(I think) chances of bricking your phone

Hey guys,
I was previously on xtresolite 2.4 lollipop rom and saw that he had a new rom out based on Marshmellow 6.01.
The instructions for the installation the new rom said to flash the new bootloader, modem and recovery before installing the new rom.
I flashed the bootloader with Odin using the BL button as instructed and how it's stuck on the Samsung Screen. I can still boot into download mode, but that's about it. It won't let me boot into recovery. Doing a bit of research it says to boot into download warning screen and cancel. Then quickly do the recovery buttons (volup, home, power), but it still won't go in.
So now I'm stuck! i'm trying to download the new stock Marshmellow firmware to see if I can install that, but aside from that I'm not sure what else I can do.
Any suggestions? Since I'm still able to use Odin, can I try to re-install the correct bootloader or is that too late? I'm not even sure which bootloader to install now. :crying::crying::crying:
Any help is much appreciated!
Thanks,
kc
as long as you can boot into the download mode, everything's alright. try flashing the latest stock rom for your model. then a new recovery, and then the new xtrestolite rom.
if something fails. do it again.... flash the latest stock rom, and so on.
Just make sure you have the correct model software for your phone and there won't be any issues. Did you backup your imei way back when you rooted on lollipop? If you did then everything will be fine if you didn't, Restore stock ROM and root, then backup your imei, hopefully you won't have any issues with your modem
Try pressing on power + vol down untill the phone shuts down then quickly press home+power+vol up before the phone starts . you will be in recovery try a factory reset then wait for the first boot. Voila !
hey all, just wanted to update. I still couldn't get into recovery, but was able to flash the stock rom and it's working as stock right now. Been using it for the past week or so and no major issues noted. I'm a bit scared to mess around again
Now that I'm on stock Marshmallow 6.0.1 rom, do I still need to try and flash the modem and boot loader for it?
Also, now that i'm on stock do I need to unroot again to install the twrp recovery? or can I just go into odin and flash it right away?
Thanks again for the help and suggestions!!!

Stock rom overrides everything so your root is long gone & you now have the latest bootloader & modem already - don't stress & no need to do anything else! If you want custom recovery simply flash with latest TWRP using Odin in download mode (in tar format using AP button). Don't root with TWRP if asked to - instead download latest recovery flash-able SuperSU (ZIP) onto your device & then flash it using TWRP. This will be the safest option for you (with root if you want).
AFAIK one always uses the "AP" button if you wanna flash <anything> with Odin - not the BL button (I've never used this). The rest are for pro's only (of which I'm not one). I'm simply a regular rom flasher & read/study/compare several guides before attempting anything I've never done before with my device. If the overall feeling is not a good one, rule of thumb is I don't proceed until I feel confident enough about what I'm attempting to do.
Good luck.

I flashed the xtresolite ROM without first flashing the bootloader and modem and it worked fine for me, if you back up everything with an otg cable onto a USB then flash the ROM everything should work fine but you will have to wait around 5 minutes for it to boot. If your still waiting after 10-20 minutes then you did something wrong and you can just wipe your entire phone then recover everything from your backup on your USB ????????
