[Q] Ubuntu On Nexus S

Hello,
I was trying to install Ubuntu on my nexus S. While installing i used the command
"fastboot flash boot bootUbuntu.img" instead of fastboot boot bootUbuntu.img.
I realized this later.Now i am not able to boot the Android 2.3 version also.
I had unlocked my bootloader using fastboot oem unlock
i am able to run the clockworkMod Recovery using the command "fastboot boot recovery-clockwork-3.0.0.5-crespo.img"
i am also able to boot in the fastboot mode.
In the fast boot mode it shows "no boot or recovery img"
I am also downloading the 2.3.3 version. Willl that help me?
please please pls help.

just use recovery and restore one of your nand backups.

I never took a backup.
Now all i get is while switching on the cell,is the fastmode displaying "no boot or recovery image found"...

You need to flash a recovery, then use that to flash any rom (which will contain a boot img as a part of it).

I am new to android. Can you give me the detailed steps how to solve my problem.
I can connect my phone in fastboot mode via the command line(Windows).
By "you need to flash a recovery" , did you meant "fastboot boot recovery-clockwork-3.0.0.5-crespo.img"
And i am not able to get anything by what you said "then use that to flash any rom (which will contain a boot img as a part of it)"..
Sorry for the inconvenience...Thanks once again...

Assuming your pc detects your phone and thd recovery file is in the same folder as your fastboot. Type this in:
Fastboot flash boot xxxxx
Xxxxx is your recovery.img file name. After that just install a new rom. Hope that helps.

1. Download ClockworkMod recovery and place the .img file in the tools folder of the Android SDK.
2. Put phone in fastboot mode.
3. On computer do:
Code:
fastboot flash recovery c:\android\tools\recovery-clockwork-3.0.2.4-crespo.img
***Note that when you do the above you need to include whatever file path and file name is correct based on your setup.***
4. After it flashes, press volume down to get to recovery, and press power button to choose recovery. After a minute or two, ClockworkMod will appear.
5. Use volume down to navigate to Mounts and Storage and power to select it.
6. Use volume down to navigate to mount USB storage and power to select it.
7. Use windows explorer to copy a flashable zip of a rom or stock rom onto your sd card.
8. Choose Go Back from CWM on your phone, back to Mounts and storage menu.
9. Choose Go Back again to the main ClockwordMod menu.
10. Choose "install zip from sdcard."
11. Choose the flashable zip file you put on your sdcard in step 7. Select YES when prompted.
12. Reboot system now.
This will get your phone back into working order. If you still want help installing Ubuntu on your NS, I'm afraid I cannot help with that.

Well now i am getting some hope.But i am still stuck at step 7.From where do i copy flashable zip or a stock rom.
I downloaded android 2.3.3 http://forum.xda-developers.com/showthread.php?t=965478
Will that help....

Yes, download it to your computer then, in CWM, mount phone as USB storage. Then on your computer copy that file, and open the E:\ or F:\ drive or whatever your phone mounted as, and paste it. Then unmount and continue with the steps.

it seems it's not working 4 me...while installing from zip file(Android 2.3.3),it says that installation failed
i exactly dont remember the exact error but it something said about "could not find /system/build.prop"..
I was able to install the cyanogenmod 7 for nexus S...

It sounds like the zip file of 2.3.3 that you downloaded was either a bad download or not a proper flashable zip. Do you still want to go back to Stock?
OK so if you still want to go back to stock, boot up CyanogenMod, download ROM Manager and then open it. Choose Download ROM, then choose Stock Images. There you should find a Stock 2.3.3 ROM you can download and flash. Then you will be back on completely stock, unrooted OTA.

if you want to keep it simple and go back to stock unrooted OTA as @matt2053 suggested, do as he said and download ROM Manager, follow his @matt2053's instructions and flash the downloaded Stock 2.3.3 image with ROM Manager.
however, if you wish to keep your current data on the phone, and not flash a new rom, you can download a custom kernel from the development forum here at XDA, and flash it via Clockworkmod recovery as a .zip file and the phone should boot up.

Thanks a lot guys...
Just one quick question,is it possible to use cyanogenmod 7 as well as android 2.3.3 simultaneously..while rebooting can i get a 'grub' kind of thing on my phone...

CM technically is based On Android 2.3.3. But I don't know of a way to set up a "dual boot" environment on the Nexus. You can on the HTC HD2 but that's the only phone I know of.

[Q] SNS Recovery Img

Hello all,
Im trying to flash a new recovery image, but none seem to be working. Im not sure if you're familiar with the file names, but Ive tried "recovery-clockwork-3.0.2.4-crespo.zip" and "3101-orange.img"(j_rodd's modification of koush's). I tried to go to the source but it seems koush's site is down right now.
The phone is unlocked, however when I select recovery from the bootloader the phone shows a package unboxing image and then an android next to an exclamation in a triangle. Regular boot is fine.
Thanks in advance.

you're doing this in bootloader, right?
You have to be in bootloader, open cmd on computer and flash through there.
You can find 3.1.0.1 here http://forum.xda-developers.com/showthread.php?t=988686

Are you on stock rom? if yes, then no matter how many times you flash the custom recovery(cwm or jrodd), once you reboot your phone and enter recovery, you'll always end up with stock recovery.( the image you are getting android next to triangle is that of the stock recovery)
what you should do is enter bootloader, fastboot flash ur recovery, and from there (without reboot) enter recovery directly. i would recommend you flash a custom rom.

[Q] I think I may have unlocked my bootloader twice...

I tried to use the search and google but didn't really find anything helpful. Almost 2 years ago, I unlocked the bootloader back on honeycomb and did custom recovery, root, and custom rom. Then a little while after ICS came out, I did the OTA update.
Today, I reset the xoom back to stock ICS and tried to unlock the bootloader again...thinking nothing of it. The process was taking a few minutes so I decided to get a snack and when I came back it was rebooting.
I assumed that it worked and continued to try and fastboot a recovery image. The recovery image installed and I did another reboot but was greeted with the android welcome screen. Anyways I went through the menus and then tried to enter recovery and it gave me an android laying on its back with and exclamation point above his open chest.
I hard rebooted and can still get into my device, but adb cannot seem to find my xoom anymore. I have tried it on a 64bit desktop and laptop with no luck.
Have I messed up? Or is there a simple fix that I am missing? Thanks in advance for any help!

Can you get into fastboot mode? The second time you unlocked did you have to go through the questions on your xoom again?

Yes, I can get into fastboot by holding the volume down key and the power button. That's fastboot, right?
Yes, I had to go through the menus the second time I unlocked.

sounds like the recovery you try to fastboot did not take or the rom was corrupt.. Which recovery was it? Do you want to be rooted and run a custom rom or completely stock? what xoom do you have(wifi, 3g, 4g)

I want to flash this ROM
http://forum.xda-developers.com/showthread.php?t=1997434
With whichever recovery is best. I tried flashing this recovery:
http://forum.xda-developers.com/showthread.php?t=1074979
I am on a 4G xoom on 4.0.4 but I don't use my data plan. I would like to be on a nice stable build of 4.2.

Download your rom choice, gapps and put them on the root of your sd card. If they are already there skip this step
I like TWRP Recovery the best. Easy to use and lots of options.
download this Twrp 2.4 img to the folder you hve fastboot in
open a cmd prompt in that o that folder
type fastboot flash recovery TWRPv2.4.1.0.img
Once you have verification on your device that this has been flashed, reboot your device by holding volume up + power.
Then 3 seconds after you see the Motorola logo, hit volume down. You should now see "Android Recovery" in the top left corner. Hit volume up to boot into recovery.
You should be in twrp 2.4
select backup/restore and backup your current system
select install and find your rom select asnd then swipe to flash
when done then select home
select install again and find the gapps package and install
when done select wipe dalvick/cache
when done select reboot
select system
you should be good to go.

Well I got through all of the steps, but when I try to boot I get stuck in a loop of the roms boot logo. Is it okay to flash a wingray rom over a stingray device?

I think it is fine just the 3g/4g won't work.
I can get you going again but you are going to be starting with a locked honeycomb device. You will then have to either let it update to ICS or JB or unlock, root, install custom recovery and flash a rom. What xoom do you have 3g or 4g?

Okay I restored it again but this time i did a factory reset and wipe dalvick before flashing the rom and gapps. It works! Thank you for your help!
However, could I ask how to root this thing?

since you have a custom recovery on it already and are unlocked.
Download this file Universal xoom root place it on the root of your sd card and flash it. Then reboot and try a root required app such as root checker

[Q] Trouble installing custom recovery on Samsung I8558

Hi,
I'm trying to root and install CWM recovery on samsung i8558 Galaxy Win (China Mobile version).
I have at hand a set of stock firmware, a pre-rooted boot.img, and a cwm recovery image (6.0.3.7) built from cyanogenmod source only with recovery.fstab replaced with the one extracted from stock recovery.
Also I've tried ROM Manager, but it won't boot into recovery after claiming to have installed CWM.
I have successfully rooted the device using the prerooted boot.img.
The problem is that when I flash my custom cwm recovery onto the phone, it won't boot into recovery by normal means (holding home, vol+, power). I can only enter recovery via 'adb reboot recovery'. Unfortunately it leaves me stuck in recovery mode, 'reboot system now' fails, 'adb reboot' fails, the only way out I've found is flashing stock recovery.
I guess my cwm image is not properly configured to suit my device. I have tried the Recovery Builder at builder.clockworkmod.com, but its output is totally out of function - black screen without anything.
Any clues?

Which CWM did you use?
I'm using i8552 with many custom Rom and finally a swipe cwm. Which cwm did you use to flash?
Also if you are on JB 4.2.2 will you send me a snap shot of your settings page, notification bar and About page?
Let's help each other here...

[Q] galaxy tab 2 system recovery

guys,
my tab2 starts up with a system recovery screen.
i started reading on the forum, and according to many threds, i ned to wipe data/factory reset and then flash a ro. so i copied a rom(omni 4.4.2) to my micro sd, wiped data/factory reset but then it stops. There is no flash option in the system recovery screen.
anyone who can help?
thanks ina dvance.

Sounds like you are dealing with the Stock recovery.
To flash a custom ROM you FIRST need to flash a custom recovery to flash the ROM.
- For CM11 flash Philz Touch or CWM Swipe Edition through ODIN3.
- For OMNI flash TWRP through ODIN3.
This means: Get the .tar.md5 from Android Andi's file repository, install ODIN3 + USB drivers on your computer, put the Tablet into Download Mode, start ODIN3, select the recovery file as a "PDA" file, connect the tablet, flash it, disconnect after flashing, get into the custom recovery (Power + Vol UP), flash the ROM + gapps.
Or ... maybe read the OP post of the custom ROM you want to flash with a bit more care and attention - it's usually pointed out that you need a custom recovery in order to flash the ROM (stock recovery won't cut it).
