[Q] How do I re-root after un-rooting? - Nexus S Q&A, Help & Troubleshooting

Hi,
A few months back, I unrooted my NS4G in order update to the official ICS release. Initially, I was content with the official ICS on my phone, however, I've come to miss the fun mods and features that are available with custom ROMs. Now, I can't seem to re-root my phone.
The bootloader is still unlocked so I tried going into recovery like old times but received a blank screen with an image of the android bot face down with its back door open and an exclamation point (pictured below).
Please help. Although I've rooted a few phones, including this one, I still feel like a rookie and may be missing something very simple.
Thanks!!!

You need to snag a custom recovery and get the current superuser. After that, you will need to make sure you either edit the script or delete the script in the system so it doesn't overwrit CWM.

CWM
The recovery needs to be pushed while in the bootloader via fastboot
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo4g.img
Recovery first, superuser flash 2nd, fix the recovery last once you've fully booted up.

When the faced down android appears , try pressing volume up button once . Helped me one time.

So how about an update? How are you going with it?
I have had intermittent problems in the past similar to yours, and I was able to solve it - where are you up to?

You should go into a command prompt on your computer then do a fastboot oem lock then unlock. (This will erase all data)
Tell me if this works

Data Management Icon

I got the Data Management Icon on the upper right hand side of my phone. when i pull down the pull bar it says downloading. does this mean its downloading ICS?? I live in the Northeast USA. BTW i was on leaked ICS and then Downgraded to GB.
I got the same update request but I dont want to click on it because I dont know what it is HAHA
I had the same notification this morning, but I'm on a custom ROM. Interesting.
I've got the same but can't apply the update because I have Cwm recovery installed (I'm still on stock rom though) can anyone tell me how to return to stock recovery?
I will hopefully have an answer in a couple of. minutes.....downloading on the wifes skyrocket now, its not rooted
Same thing showed up on my phone this morning.

You need to get a copy of the stock recovery.img. Then place the image in the root of your /sdcard. Reboot to CWM recovery. Connect your PC to your phone.
1. Mount emmc in cwm recovery
2. adb shell
3. su. Don't need root here but can't remember since it has been awhile.
4. dd if=/emmc/recovery.img of=/dev/block/mmcblk0p22
5. Exit, exit
6. Reboot system

[Q] Flashing Packages in Recovery

I know how to install a custom Rom but for some reason last night whenever I tried to flash a new rom, I kept getting an error in recovery saying something like this
" E:/ "filename" could not find " or something like that
Then it said Installation aborted.
This happened every time whether it was a rom or a tweak package. Its not my SD card because I tried two different ones. Is it my phone or the clockwork recovery?
Go to www.4ext.net download, install (choose the touch version from within the app) and report.

If you can't then you may need to find a different way to flashing a new recovery to see if that works. The hack kit has the option to only flash a recovery.
You could also flash a ruu as last option.

What do you get with the command: fastboot devices?
Why is GooManager not working for you? Did you install the open recovery script through it?
Did it ask for su permission when you first ran it?
Are you sure you are unlocked and in the bootloader menu when running the first fastboot command?

yeas and yes, i figuired it out, i thought it would come up on its own, but you needed to hit the rocket up on the first load, than it went into the twrp. kind of a derp moment didnt finish the instructions fully i guess. once i figuired that out and got my rom on, install from their. everything is done

[Q] Scrambled Display

I had My HTC One S working fine with an unlocked bootloader, CWM Recovery, and CyanogenMod 10.2. One day, I get a notice that there's a system update, so I thought, hey that's cool, over the air updates for CyanogenMod. So I do it and now when it boots it looks like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
With some difficulty, I was able to get into the bootloader then into CWM. I cleared everything and re-flashed the original CyanogenMod ROM, but it still does this when it boots. It also does not appear to turn on properly. Does anybody know what's going on here?

Your link doesn't work.
I also cannot see any picture of your screen, but I think you mean freaky colours on your screen.
This is due to updated display drivers some time ago on CMs side.
Which means if you use a newer ROM, you also have to use a newer kernel to get the correct colours back.
If you are S-On your kernel won`t be updated by just flashing the firmware, you have to fastboot the kernel afterwards.

Sticky Recovery

Hey everyone,
I have this issue with my device hopefully you know something about it: a while ago I rooted it, got Magisk on it all that. The device was just out so updates were still coming strong--or maybe I payed more attention to them than I do now, IDK--the case is that I accepted one of them and it undid the root and updated MIUI to something-something, regardless, since then I'm unable to flash a recovery image.
I thought the partitions got messed up or something and flashed the official system with the official Xiaomi spyware/adware suite "tools" hoping it would rewrite what needed rewriting then I tried flashing the recovery (TWRP) but no luck.
I'm using the XiaomiADBFastbootTools Java applet. It seemingly flashes the thing successfuly then it boots right into the system again, not in recovery. If I use force a recovery reboot through adb or with the buttons (which I've already forgot which were) the recovery the comes up is the official one, not TWRP.

}
Every time finishes "successfully", then the device reboots taking just tiny bit longer then I see the MIUI logo with the sort of paint-spill animation covering it and then I'm back on stupid Mars again (the stock pseudo-interactive wallpaper). Not even my information is lost--not that I'd want to, but at least it'd be something.
Since I removed most bloat the phone became pretty much useless and I wasn't even thorough because there's stuff that just can't be removed. Rooting would allow me to get some utility back out of it. Can it be fixed at all??
