How to Install a ROM on Nexus S or Nexus S 4G!

I know some of you are having trouble with installing a new ROM on your Nexus S or Nexus S 4G, so let me go over it again.

Before we begin, copy over the ROM zip file you want install over to the internal storage of your Nexus S or Nexus S 4G.

Step 1. Install ROM Manager from the Market.

Step 2. Choose “Flash ClockworkMod Recovery” to update to the latest ClockworkMod Recovery.  You only have to do this once or whenever there’s new versions.

Step 3. Choose “Google Nexus S” for regular Nexus S and “Nexus S 4G” for Nexus S 4G.

Step 4. You should get a successful screen like above.

Step 5. Choose “Reboot into Recovery” to boot into recovery.  You can also install a new ROM using “Install ROM from SD Card” but just in case something goes wrong, let me show you how to do it manually or if you have to zip Google apps separately.

Step 6. Choose “wipe data/factory reset” using Volume keys and hit the Power button to choose.

Step 7. Choose “Yes” and hit the Power button.

Step 8. Choose “install zip from sdcard” and hit the Power button.

Step 9. Choose “choose zip from sdcard” and hit the Power button.

Step 10.  Choose the ROM zip file you copied over to your internal storage and hit the Power button.

Step 11. Choose “Yes” and hit the Power button.

Step 12. Choose “choose zip from sdcard” and hit the Power button.

Step 13. Optionally, if your ROM requires you to flash Google apps separately, go and flash the gapps zip file also.

Step 14. When everything is done, go back to main menu and choose “reboot system now”.

Step 15. Your phone should reboot and you should see the new ROM come up.

Congratulations, you’ve installed a new ROM on your Nexus S or Nexus S 4G.

  1. rohan jit singh says:

    in which folder do u paste the roms in the sd card ?

  2. Philip says:

    Great tutorial! I do have a few questions though. Would I need to install Rom Manager everytime I flash a rom? Is it because flashing removes the app? I also noticed that you have several roms in your sd folder (saw all those zip files). Do those files get deleted upon flashing or not?

    • Nexus S Hacks says:

      You only have to run ROM Manager flashing part once and no, the files don’t get deleted, you can delete them however after ROM installation.

  3. Tom says:

    Just wanted to give a heads up…

    I have had an issue with ROM Manager being unable to grant itself super user permissions in the Flash ClockworkMod Recovery set.

    My workaround (and I don’t know enough about this process to know if this actual worked or if I got lucky) was to use the “Fix Permisions” dialog under the Utilities section of ROM Manager.

    Keep up the great site, it’s been really useful!

  4. Rustam says:

    THANK YOU VERY MUCH!!
    Yesterday I rooted my phone for the first time (Nexus S) after using it for almost a year! And today installed my first ROM (MIUI)! All thanks to YOU!!

I’m now not Able to use tango or Skype, also I’ve lost the capability to use the Google wallet feature with the NFC. Any suggestions on how I can get these functions back? Thanks

  8. Daniel says:

    Thank you very much for your videos.

  9. liam says:

    ive tried installing cyanogenMod on my nexus S but as i flash it comes up with

    assert failed: getprop(“ro.product.device”) == ”
    crespo” || getprop(“ro.build.product”) == “cresp
    o” || getprop(“ro.product.board”) == crespo
    E:Error in /sdcard/update-cm-7.0.3-NS-signed.zip
    (status 7)
    Installation aborted.

    Any ideas is much appreciated

    • baldock says:

      @liam

      try making sure to go into market and download ROM Manager, grant it SU permissions, and then install the latest version of Clockwork Recovery, which is the first option in ROM Manager, this got rid of the error for me!

  10. Soheeb says:

    on Step 4 I get the following message: An error Occurred while attempting to run privileged commands! any help would be appreciated thanks :D

  11. nathaniel kenyon says:

    i was wondering why in the app rom maneger i try and do the flash clock work mod recovery and it says an error occurred to run privileged commands what do i do can any one help

  12. ambarish nair says:

    * i flashed my clockworkmod recovery
    * but when i reboot into recovery..it reboots and gives me a forever staying YELLOW EXCLAMATION MARK!!
    have i bricked my phone>??? please reply soon ?? thankss… :(

    • Same thing happens with me.. Its not bricked as you can do a hard reset (remove the battery and then again put it in) But that just discourages me to install the rom because if during the process something like this happens, then my phone might be bricked :-/

  13. Ram says:

    Thanks a lot. All your videos helped me a lot. Successfully flashed and installed ICS 4.0.3 :) Thanks a lot

  14. Ram says:

    Thanks a lot. everything worked perfectly fine. I am new to all this but your videos helped me root and install cyanogen mod 4.0.3 on my nexus s 4g without any error. Thanks!!!!

  15. Chirag Verma says:

    I can’t find any fix for this error that shows on screen while installing the clockworkmod recovery “An error occurred while attempting to run privileged commands” please reply to the messages, i think there are others also who are facing the same issue

  16. Deepak says:

    Thanks a lot man :)
    Successfully rooted my phone and installed the ICS ROM.
    Thanks for such an easy step by step guide.
    Just not sure about the battery usage.
    Currently Android OS & Android system is consuming too much of battery.

  17. glenn says:

    can i use rom manager even nexus s is not rooted or a phone must be rooted in order to use rom manager….thanks any help will be greatly apprciated….

  18. Michael says:

    do i need a sd card to do the roms because i dont think my phone has one

  19. Colin Tudor says:

    Im quite new to Android but am I right in thinking, I can have numerous roms stored on in my nexus s memory and install as and when I wish?? Im ready to install a rom. Im rooted and have installed Clockwork Recovery and atm, Im looking around at roms. If I can have as many roms stored on my phone as I want, I can just change them whenever I get bored. Thanks guys

  20. P Raddy says:

  26. Chase says:

    Yo thanx for all the info and “how too’s”. But im a bit of a noob and i messed up big time..BRICKED.. I have a Nexus s on I9020XXKB3 i think, i cant check because its bricked atm. I was trying to install CM7 after i rooted via your method and i kept getting the “SD card error number 7″ when trying to install .zip from sd card. Because of my fat fingers i miss clicked and formatted everything in fastboot thus deleting my restore to the stock firmware.
    I then tryed to flash back to the stock rom but of course i flashed the wrong rom it was a I9020T…..
    It now wont turn on, or show anything on the screen. i have tryed a few methods to no avail; Unbrickable Mod and oneclick, but both programs cannot detect my device…. help me pleas, do i need to jtag it because that would be a suckfest.

    • Nexus S Hacks says:

      Can you still access CWM? If so, get a microSD to SD converter, then format your microSD on your computer, then install a new ROM, probably the fastest way.

      • Chase says:

        No i cant get it into cwm. the phone is completely unresponsive. shows nothing on screen.

        • Chase says:

          What i did is probably the worst thing u can do to a rooted droid =[ lol. In cwm i formatted i think all the partition’s on the phone, if not most. then without a reboot and realizing the awsomeness of what i just did; i tryed to flash a new rom into the phone.. it was the wrong one x[ .. ima phone killer /cry
          Is that a Hard brick ??

  27. rokkie says:

    Thanks a lot for the explanations. Cheers

  28. Strife says:

    Guys i installed Bigxie ROM + Matr1x Kernel, after i reboot my phone, the screen just stay at the “apex”(the very beginning loading page) for a long time… can i know what happen?

  29. Tom says:

    I followed your instructions and installed the ROM you published on Jan 22nd and even though it said the installation was successful, my Nexus S seems to be stuck on the start-up animation (those colorful tiles) and won’t load my phone… It’s been like that for several minutes.

    Any ideas?

    Thanks

  30. Euan Wilson says:

  31. Jose Rivera says:

    I am sorry, but you are not explaining the exact procedure to install the ICS Matr1x Kernel combo. I first rooted the phone, and then installed the ICS and at the same time the matr1x kernel. My phone does not work know, and I don’t know what to do. I hope you can help me before I smash it to the wall. Heeeeeeeeelp!!!!!!!

  37. Srikanth says:

    I recently bought an unlocked Google Nexus S GT-i9020T from eBay. The Device works fine on Tmobile network and bootable screen showing the Status=UNLOCKED.
    When I got it to India and tried inserting an Airtel SIM in it. The phone shows complete Signal strength but says emergency calls only. On the lock screen it says insert SIM.
    When I search for available mobile networks it shows my network but unable to connect to it. It does not even ask for unlock code when I insert a SIM from another carrier.
    Is this because the phone is locked or is there some other problem?

  38. Anthony says:

    Hey I have a quick question.
    So I know that every time you install a ROM you have t wipe it and reset it to factory settings. This sucks Obvs. So do I really have to install all my apps again every time or is there a way have all your apps come back? I used like 4 diff ROMS and each time I just been re-installing all my apps! So annoying! Please tell me there’s a better way!
    Thanks

  41. Billson says:

    Hey There,

    I have rooted my Nexus s and i started searching for new ROMs via ROM manager. I then downloaded a MIUI.us ROM and it is completely different to the ROM i had previously. With the previous ROM, i could easily access the google play store, down load my apps and what not. Now i can’t even do any of that. There’s not even a menu button. Is there a way to retrieve the ROM I had previously? If you can, please reply. this is very urgent

    hey plz help me geting error while installing clockworkmod from rom maneger so how could i instal new roms

  44. Paul Brett says:

    Hi, I hope someone can help me. I rooted my 9023 using the method here and installed a CM9 ROM no problems everything worked fine. At a later date I tried to install an original ROM, I did a data/factory reset and a cache wipe and tried to install the new ROM I keep getting the following message when I try to install any new ROM

    assert failed: getprop(“ro.product.device”) == “crespo” || getprop(“ro.build.product”) == “crespo”
    E:Error in /sdcard/i9020t_i9023.zip
    (Status 7)
    Installation Aborted.

    I can install the gapps without any issues but no actual ROM.

    I’ve read from above that I should update CWM but everytime I try to boot the phone I get the message

    “Unfortunately, Setup Wizard has stopped.” and an OK button. Pressing the OK simply brings back up the same message.

    Can anyone point me in the right direction?

    Hello everybody,
    I NEED HELP!!
    Thanks for your work in trying to improve our phones.
    I loved that someone would answer me some simple (difficult for me) questions about installing roms, I have installed a jelly beely rom on my Nexus S (I bought it like that) and I’m not sure which kernel I have installed, I have installed cwm and have already made a backup of my rom.
    If I install a rom + kernel-combo can I reinstall back to my old rom backup, even though I have installed another kernel?
    How do I know which kernel I have installed? and what are the roms that are compatible with it?
    In contrast with many roms, rom-combo available, not sure which rom install for everyday use, some suggestions??
    I have a beautiful i9023 and work well with the current rom, I already had a hardbrick with my galaxi mini (rom manager) now I have some fear, was still under warranty and came as new, then decided to install CyanogenMod 10.1 (without rom manager) on galaxy mini and everything went well, amazing rom, and would like to install on nexus s …
    PLEASE HELP ME …
    excuse me for my bad English (google translator) …
