[Q] Nexus S not working...

I'm going to probably get a lot of hate for this because there are a ton of forums that might get me here. I did search for about 3 hours tonight and discovered some things but am still confused. I hope someone can help this be more simple. So a friend has a Nexus S that isn't working (I have a Nexus S by the by too). It's unlocked but no ClockWork on it. I can press volume up and power to get to fastboot mode. When I click on "reboot," the phone will just loop on the Google logo. If I click recovery, it starts to boot then shows the triangle with the exclamation mark. From there, I can press power and up or down on volume to get the blue screen which says reboot system now, apply update, wipe, wipe. You get it. I'm stuck...I can also turn off the phone, hold volume up/down and plug in the usb to get to "downloading..."
I want to get this phone working and back to stock. I have the SDK Manager (my phone isn't rooted so I use it to take screenshots) and pda net (which I still don't understand why or how to use with this) and two versions of Odin. It seems like Odin can get this working but I can't get it to work or find a clear guide on how to use it and which ones to use. This is a Tmob Nexus S, I think the i9020. Any help would be so greatly appreciated and I will give you all the credit. Oh, and i can pull up the device on ddms with the sdk manager and can explore the files but there is nothing. I can't find a way to drag a file on the phone to "apply update from /sdcard." Sorry again and thanks again!

It seems your boot.img file either corrupted or missing.
Find a working copy of file, flash it via ADB interface or fastboot. Flash recovery file CWM. If that doesnt work, Try flashing CM7 Rom or someother ROM.
Did you check http://forum.xda-developers.com/showthread.php?t=895545 ?
Odin should be your last resort, if nothing really works for you.
If you want to return to stock, simply flash the NAND backup found here: http://forum.xda-developers.com/showthread.php?t=884093 .

Thanks so much for the quick reply. I think I've made some headway...I can "see" the device with cmd by typing adb devices. After that though, I don't understand how to get the stock nexus s rom on the phone. How do I move that file to my phone (what's the line of code I type)? I've tried "adb install <c:\grh78> but it says the syntax isn't correct. Any more help is so greatly appreciated and I appreciate the already prompt response. Thanks!!!

Download your rom of choice (stock, custom)
Flash Cwm via fastboot if you haven't already
Boot into recovery.
Use adb push to push your zipped rom to the sdcard (adb push file.zip /sdcard/file.zip)
Use cwm to flash this zip.

Wow fast responses. I bet it's annoying to help yet another person having issues (again, phone was given to me like this but yeah...) while you guys or gals already know how to do these things very well. Here's where I'm stuck. I enter this code in cmd:
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
and it just says < waiting for device >.
Here's a pic of the screen that I'm on with my phone when i enter the command.
http://imgur.com/Pey3W
If I'm just in the first screen by holding volume up and power, the computer won't read the phone. So I click recovery, the screen shows it's trying to install something then the triangle exclamation mark, i press volume up/down with power and get this screen and the computer can "see" my phone on cmd.
How do I get this flipping clockwork on this phone or get the stock image on my sd card? Thanks again for helping me out guys. I have taken a look at the links you have sent me and that's where i found the download as well as the code to enter. I will keep looking at them but if you find a faster solution, please let me know.

One more thing to be super clear on...when I'm on the screen on the Nexus S that says Fastboot Mode on top in red and Lock State - Unlocked...my computer won't read the phone, therefore I cannot fastboot the recovery img...

So you already tried "fastboot devices" while in fastboot mode?
Edit: Actually it sounds you really want stock so download the complete stock OTA ROM (including boot.img etc.), rename it to update.zip and put it on the root of your sdcard. Boot into the stock recovery like you did already and hit apply update.
EDIT: Go here to download the correct OTA http://forum.xda-developers.com/showthread.php?t=1056062
Find the correct 2.3.6 "Full ROM" for your phone model. Sounds like in those instructions you don't need to rename to update.zip. Haven't seen stock recovery for a while so I don't remember.
If there is a wipe option in the stock recovery then do that first.

Yes I have tried fastboot devices in fastboot mode but nothing because my computer doesn't read the phone in that mode. And yes, I want to put the stock rom on there but that's the key, I can't get access to the root of my sdcard. I can't push anything into the sdcard to flash it. Any ideas what to type or how to access the sdcard? Thanks a million, billion.

Also, I can't get the phone to boot at all, like I can't get passed the Google Logo if I reboot so I can't access the sdcard in the traditional way.

Connect with adb and type this:

Then type:
adb push rom.zip /sdcard/update.zip

If fastboot devices returns NOTHING then this is most likely a driver issue. Remove the device through device manager, make sure you have a recent SDK (for the USB driver) and let it re-detect.

If you can get into the boot loader and get a proper USB driver you should be able to flash a recovery.
Once you've flashed Clockwork Mod (recovery) you'll be able to push to the sdcard using ADB or possibly mount the sd card through the CWM menu (although I've yet to have that work).
In order to get a recovery flashed though you need to get fastboot to see your device (unless you can already boot into recovery, then just use ADB).

If he's stuck at the Google logo and has a trash boot.img it's not likely he'll be able to get a shell via ADB. Now, if the system is hanging starting a device or looping during boot then that's possible.

He said he can access stock recovery and has connected with adb, unless I read wrong.

Indeed - I saw no clockwork and figured he'd toasted his recovery image as well, but it does look like stock recovery is there. ADB should push fine to the sdcard from recovery then.

More...so if i type in adb reboot bootloader in the recovery screen, it does just that...great. But then my computer makes a noise, a double tap if you will...like a dun dun, like something didn't work. When you plug in something to the computer it usually goes like dun na...but the phone clearly won't read when I'm in bootloader/fastboot mode. So when I type a command, nothing will work...

That noise is that it detects a device has been connected (assuming a recent version of windows). If you want to flash CWM you need to get the driver sorted for the device. No amount of plugging/unplugging is going to fix it.
If you have the stock recovery you can boot into the stock recovery, use adb to push the full OTA package to the sd card and then just flash that from the stock recovery.

Go to the stock recovery like you have done before and type the adb command I wrote above.

Thanks is all I can say. Okay so when I type in the command, this is what I get:
- exec '/system/bin/sh' failed: No such file or directory (2) -
the "stock recovery" I can get into is the picture I posted a link for. That's what I can access as well as the fastboot mode when I first turn on the phone with volume up/power. But when my computer makes the noise that it's connected (using Windows 7 64bit) it makes a different sound then the normal "device connected." Like it's corrupted.

by the way...if we can get this working, I'll post a picture of me holding the fixed phone!

Bricked :(

All im getting is the TWRP menu, even after holding the vol down & power. Wont get to the rck screen. Any ideas?

What happened?
This is a common result if you flash a non-4.2 twrp on a 4.2 bootloader, which will cause a fastboot flash brick.
You will need adb drivers installed on pc, then while in recovery connect your tab to pc, open a command prompt and cd to you android-sdk/platform-tools folder and type
Code:
adb devices
if adb is setup correctly you will get a response with your devices s/n. If this is ok then type
Code:
adb reboot-bootloader
which will reboot your tab to the bootloader screen.

The problem is that whenever I boot up, all i get is the TWRP menu, not letting the pc see the pad. On device manager I get Transformer under other devices. Ive downloaded the drivers, but its not installing them. When I run adb reboot-bootloader, I get device not found.

Have a look here, scroll down and follow on from the where you see the device manager image - this worked for me to get adb working from recovery.
So did this happen after you flashed twrp 2.4.4.0-4.2? or did you flash another twrp or cwm?
Heading out now for a few hours but will be back later

TF300t constantly booting into recovery

I have a TF300t that I have been doing custom ROMs on for over a year now. Not to long ago it messed up and I ended up doing a ADB side load of the the current software from ASUS to recover it. I wanted to try CM11 so I followed the directions to get the right version of TWRP installed. I noticed that it was really slow at stuff like wiping cache and dalvik, so I decided to reflash TWRP through ADB instead of a zip file.
All went well and I got into android and went into TWRP to see if everything went okay. I'm in TWRP, but I cannot do anything. Only system will mount and it says I am not rooted and wants to install supersu. If I reboot or power off it just goes back into recovery. Doing the power + vol down will not get me into the bootloader and will instead just power cycle at the ASUS logo.
Any idea on how to fix this, or did I just royally brick my tablet?

When you first reboot back into TWRP, try running fastboot commands. You may be able to reflash your recovery, or follow Buster's recovery method from there on.

I just get stuck at waiting for device. Is there a section I am supposed to be in? Or do I do it from the home screen for twrp? I checked device manager and it does have Transformer listed in other devices.

It's not finding anything and ADB sideload fails. I'm doing the fastboot commands from the fastboot folder I have been using with other fastboot stuff for the TF300.

hmm idk. Im guessing you flashed the wrong version of TWRP, which has ended up in a brick for most users, but they had fastboot access and could later recover it using this: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12. You dont seem to have either ADB or fastboot, and TWRP is in a non working state. You could try reinstalling your fastboot and ADB drivers with the universal naked drivers, and then retrying ADB reboot bootloader and fastboot.

All fixed!
Here is what I did.
1.) Installed naked drivers following the guide at the link provided above. This allowed me to get into the bootloader, but I was unable to successfully flash anything.
2.) So, I followed this guide: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
Probably lost all my user data, but worth it for a working tablet.
HUGE thanks to cmendonc2 for the help and ultimately leading me to the correct solution.

i have no rom in my sdcard to flash..
how can i send files to my phone?
how can i fix this?

Can you access fastboot (press down and power)?
If you can then you may be able to flash a new rom via fastboot or maybe push one in recovery via ADB.
However, I've never done this before (on this device or a similar situation) so I'm only being theoretical here unless someone can confirm it and I suggest researching first.

Fixed it using adb sideload. So simple and easy to fix for any missing rom in storage

[SOLVED] I need an urgent help!

Hello. I have a Poco X3 NFC and this is my problem:
I had OrangeFox recovery on it. I wanted to install another rom (from Arow OS because it wasn't work well), and one of the requirements was a decrypted device. I've flashed a file which is said it can decrypt it (and it did). After the flash, I rebooted my phone and everything was fine until I rebooted my phone again. Now the recovery bootlooped, the phone can't boot the system and adb doesn't recognize my phone in fastboot mode. It's weird that when the phone stucks at OrangeFox logo, adb recognizes my device (as in recovery mode). So I type the command "adb reboot fastboot" and it loops at the recovery again. I can go fastboot mode but fastboot doesn't recognize my phone, so I can't flash anything either. It's 4:20 a.m. in here and I can't sleep because of this.

When I plug in my cable, I can hear that "something is plugged in" voice in my pc. When I look device manager, it shows the phone as "Android Composite ADB Interface". When it stucks in recovery, it doesn't quickly boot so I can see my device in adb:
List of devices attached
940ab842 recovery
this is showed in adb when my phone stucks at recovery, but I can give commands like "reboot".
But when I type " reboot system", it doesn't reboot it system and just tries to open recovery mode, and recovery mode doesn't open, just loops.
I type ''reboot fastboot", but it still tries to open recovery and again, it loops.
I type "reboot bootloader", at this time, it can boot to the fastboot mode, there is an orange "fastboot" word at the middle. When I go back to adb and type "adb devices", it shows nothing.

I think Arrow OS files still in my phone but somehow it pretends like it can't detect them. And it wants to boot directly to the recovery mode but the another problem is recovery mode stuck in loop. When I want to flash a new recovery, this time I can't connect my phone to my pc when it's in the fastboot mode. It's like a problems chain and I couldn't find any exit.

DUDE I ****ING SOLVED IT!
FIRSTLY, **** ORANGEFOX, if anybody see this do not use orangefox.
Secondly, actually I still have the same problem. TWRP is also stucks at the loop, but there is an interesting difference that TWRP tries to loop one time and after the fail, it suddenly boots the system.
And since I can flash something with fastboot, now I think i can save my phone. Now I'm trying to install stock rom, i'll update after.

How I solved:
Installing the Google Universal USB Drivers. It has a weird method to install, and I wasn't know you can install a driver even the phone is in the fastboot mode. So thanks to that I was able to install usb drivers and finally I could get fastboot to recognize my device. The first thing I did was installing TWRP.
My problem was not solved even I installed TWRP because TWRP was doing the same thing, but one thing was different: TWRP was trying to boot recovery, it couldn't and after it was booting to the system. So I've realized how amazing TWRP is. But it wasn't solved my problem completely though, I think its problem is related to that decryption file.
Currently, I've managed to install stock rom and I haven't encountered any problem.
And I'm happy because my mother won't beat me with her slippers.
