[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:
adb shell mount /sdcard
Then type:

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!

[Q] Nexus s 4g locked up

Okay, first of all I know, I'm a total noob. I have followed these forums a long time and have successfully rooted a few phones. One of which was my nexus s 4g. I was trying to unroot the phone so I could get ics. This is when I ran into problems and right now I just want to be able to get my phone working again. Right now I am stuck on the Miui boot up screen and no matter how long I wait it stays on that screen. If I do a battery pull and hold down power and vol up I can get into the bootloader screen with the information as follows: fastboot mode, product name-Herring, HW Version Rev 34, Bootloader version-D720SPAKE1, Baseband version-D720SPAKE1, Carrier info, SPR, serial number-37308B81276A00EC, Lock State-locked. Then the different options I can choose are reboot bootloader, reboot, recovery, power off. If I choose reboot, it takes me back to the mius screen and stays there. If I choose recovery, I get the triangle with the exclamation point. I then hold power and up volume again and I get a screen that says Android system recovery <3e> with reboot system now, apply update from sd card wipe data/factory reset and wipe cache partition. I have tried all of these as well with no luck. When I go to apply update from sd card I get matrix-cfs_v15.5 zip, root.zip, update.zip and then what looks like apps such as Alarms/, Android/,MIUI?, etc. If I try to select any of the first ones such as matrix-cfs_v15.5 zip, I get Install /sdcard... , finding update package..., opening update package..., verifying update package..., E.signature verification failed, Installation aborted. Then it gives me the system recovery options again. Any help would be appreciated.

Did you try ADB fastboot method?

Not sure how to try that

I tried doing the adb, followed all directions and installed and when I go to the command prompt and type in anything, such as, adb reboot bootloader I get, adb is not recognized as an internal or external command, operable program or batch file.

ok I got that working now but when I type adb devices and press enter I get a message saying List of devices attached and then it doesn't show anything and I get the command prompt again saying:c:\android\android-sdk\platform-tools>

also since the phone is stuck in either the miui screen or bootloader I can't get into it to put it in usb debugging mode. I am trying on my own to get this going and am stuck any and all help would be very much appreciated.

I think that means you have a locked bootloader.
And from what you're telling, I believe you have stock recovery.
Also, when you're in fastboot mode, I don't think adb commands apply. Use fastboot commands instead (i.e. fastboot devices).
Search for guides showing you how to install and use fastboot.

I did fastboot as well and the problem I think I am having is it's not recognizing my phone because usb debugging wasn't turned on before it locked up. How would I get it to recognize my phone or download an img to my phone if it is not being recognized. Sorry if this is a stupid question.

You don't need usb debugging in fastboot mode.
You either:
1. Don't have drivers installed.
2. Don't have fastboot installed correctly.
You really need to read a guide or two, through and thoroughly.
Bc it sounds like you have no clues.

Yeah dude. Take a step back and go over what you have installed and where you installed it.Yes, fastboot commands start with fastboot instead of adb. And you're on stock recovery.

Thanks for the answer that I don't need usb debugging in fastboot mode, I wasn't sure of that. I have downloaded and installed my drivers multiple times and when I use the device manager to update drivers it says I have the latest drivers installed already. Whenever I do fastboot commands I will type in fastboot devices and shouldn't my device serial number come up? It just gives me the line c:\android\android-sdk\platform-tools>
And is waiting on me to type a command in. And yes I have been looking at guides all night. I appreciate any help you guys might have and remember we were all noobs at one time.

The zip in this tutorial should help.
It has adb, fastboot, and the drivers needed.
And unlock the bootloader because it is locked.

Finally got it, I had everything downloaded that I needed already, but looking at different forums, etc, it seemed like everyone named it something different. So I just used the one link you gave me and did it exactly the same way and it worked. Thanks so much! and again thanks for your patience.

USB device not recognised on none of my PCs

A week ago I faced this error for the first time but didn't have the time to take a look at it so I just downloaded Air Droid as a temporary solution. But then more problem appeared. The battery indicator wasn't working so I decided to fix it somehow. To dig on Google. I tried flashing different ROMs and recoveries and on and on. the problem is that I'm now stuck on bootloader. I have no system installed and that crappy TWP won't start. The splash screen just flashes and that's all. So my phone is now a brick and I just don't have any more ideas. I need to lock my bootloader somehow so I can take it back to Samsung establish some kind of USB connection so I can install a new atleast,
Any help would be very much appreciated.

Hello,
I assume you are using a windows pc (correct me if i'm wrong)
Use this forum > http://forum.xda-developers.com/showthread.php?t=1901617 to install drivers for your nexus s.
Afterwards, reboot your PC
Do you have adb installed? If so skip this part:
Install minimal adb and fastboot using this forum > http://forum.xda-developers.com/showthread.php?p=42407269
Try inputting fastboot devices into the terminal window and see if your device shows up
Then you can flash everything back to stock. You can do this by following the following steps:
Go to this link and download the appropriate files for your nexus s >https://developers.google.com/android/nexus/images
Use a program such as 7-Zip to open and uncompress the package to a folder of your choosing
Navigate to that folder and try clicking flash-all.bat
Hopefully that will flash your whole phone back to stock. If not you will have to manually flash each part. Do this by typing the following into the terminal, one by one, replacing the file names with the appropriate ones for your nexus s.
fastboot flash bootloader bootloader-crespo-i9020xxlc2.img
fastboot reboot-bootloader
fastboot flash radio radio-crespo-i9020xxki1.img
fastboot reboot-bootloader
fastboot -w update image-soju-jzo54k.zip
For example, for the first line of code, I would go into the uncompressed folder and hold down shift while right clicking the bootloader file. I would then select “copy as path”. Then I would go back to the terminal and type “fastboot flash bootloader ” then paste the path I just copied. I would then repeat for the rest of the items.
Feel free to ask questions if it does not work. Ill try to reply as soon as possible. Cheers.

Thanks I solved it. The problem was with my phone's USB port. Atleast the usb module/part of the port. I put a little metal in it then moved it around a couple times.. tried to save it. Somehow I got it working again, so I instantly flash a working recovery then went back stock. I returned my device to Samsung (It was under warranty) and they fixed it.
Cheers

[Q] Switching from CWM to TWRP: How to?

I am really confused since having to use ADB and flashboot. I am thoroughly confused that someone has not simply written step by step instructions for this in a sticky so newbies like myself can follow. With that in mind I am trying to change from CWM to TWRP. I have the files but completely oblivious on how to get things to work again. I go into a command propt and start adb or flashboot but cant seem to get it to find the device. Now I cannot find the instructions I used to install CWM. Can somoene kindly help with either a link or instructions to make this change so I can be good and flash some ROM's?
Thanks,

1) Power your phone off and once its off hold down power + volume down until its booted into HBOOT/Fastboot mode (bootloader).
2) Place your TWRP img file in the platform-tools folder where your adb/fastboot files are.
3) Shift + Right click inside of the platform-tools folder and open as a command prompt.
4) If you're not already, switch to fastboot mode and assure it says "Fastboot USB" or just fastboot at the top (don't remember if it says USB or not) and then in the command window type the following command and press enter: 'fastboot flash recovery name.img'. Replace "name" with the file name of your TWRP img.
5) It should say "successful" and then from there you can navigate to your new TWRP recovery via the bootloader by navigating with the volume keys and selecting the "Recovery" option by pressing the power button once its selected.

Really appreciate what you said but I am running into the issue in the command prompt. When I type the commands it says
error: device not found
I have rebooted both phone and computer but it never seems to find the device now and not sure what to do.
Do you have any suggestions on do I start adb and run any commands, SU, fastboot, or what? I know its working because the computer sees the devices by an external drive. The phone is able to go into fastboot on reboot as well. I just do not know where my dilemma is.

Do you have USB debugging enabled under developer options?

I'd assume this means you haven't installed the proper drivers? Well actually I'm not really sure these even relate to the fastboot drivers BUT worth a shot to fix your problem!
Download HTC Sync Manager from here and install it and let it install the proper drivers for your M8 (with phone powered on of course) and once they are installed and it's done make 100% sure you UNINSTALL HTC Sync Manager after, only the program, not the drivers themselves.
After that re-attempt it and also as the other guy said, enable USB debugging all though I don't think it will do anything unless the phones booted into Android(may be wrong).
Also see if you can get ADB to work while the phone is running. Instructions for testing ADB would be turn the phone on, enable USB debugging and in the command prompt type
Code:
adb devices
and if it pops up your device then you should be good. If it doesn't then it's most likely related to the drivers and I would recommend you uninstall all drivers and remove every trace of them. My prefered method of uninstalling them is using Device Manager (windows tool) to uninstall the drivers and then use USBDeview to remove the rest/traces/etc.

OK finally found the phone and flashed putting TWRP on it for recovery. Thank you very much. Using the ADB and FASTBOOT are things I guess I truly need to learn. So, with that I thank you and now I feel good about beginning my ROM flashing.

I basically went in and did the adb devices. Once it seemed to see it I had to do the adb reboot bootloader then do the flashboot flash recovery twrp img. Now I have it working and about to flash santod's NuSense ROM since I used it on my thunderbolt that was recently replaced by this. Wish me luck LOL.

Flashed stock recovery and thought I soft bricked my shield tablet.

First I'll give credit where it is due. From two threads on this site is where I got help with this issue:
I followed THIS guys steps for manually erasing and got the recovery images and lots of other useful information from HERE. Thank you guys very much!
OK, so, hopefully I can help someone with my little story as well. I was having issues with apps and programs crashing on me with lollipop and the new marshmallow update. The tablet just wasn't working properly and moving slow. I even had the SD card holding all my apps and larger files so I didn't overload the internal storage. So, I decided I wanted to flash back to factory/stock recovery and go from there. I did this using THIS method. I flashed via the "flash-all.bat" file (the command in fastboot is the same as the file name). I should note that there was one instance that failed during the install (I did try it again and got the same failure). Said something about “did you mean you wanted to flash this partition” or something, then showed it failed. After flashing I hit continue on the bootloader screen of the tablet and it said it was "cold booting." After about 5 minutes or so it started to boot but never made it past the NVidia screen. I tried wiping the phone with factory reset, wiping the cache, etc. and then re-flashing the recovery (again with the .bat file). I tried flashing TWRP but it didn't install apparently, because it still went to factory recovery. I even re-locked and then unlocked my bootloader to see if that would set everything straight. Nothing seemed to work. I knew I would eventually find a solution though so I kept looking. Stumbled on some other people that had the same issues but no solution (hope those people got it figured out). So here's what I did after some more research:
First, if you're in this situation and you did factory reset to try and resolve the problem, you may feel like you can no longer communicate with the device via fastboot/adb, but as long as you have the usb drive and your SDK tools installed (I used CodeWorks for Android all-in-one program) that shouldn't be a problem. You'll just have to be in the bootloader on the tablet.
-If for some reason you deleted or uninstalled your drivers and tools you'll have to download them again and then, the computer should still be able to communicate with the tablet. In the device manager under portable devices it will still show up as Module something or other. So the computer still sees the device but doesn't fully recognize it yet. Don't worry, this should still work! Just make sure you that fastboot is seeing the device by inputting "fastboot devices" in the command window and a 14 digit serial number should pop up. If it just says "list of devices" or there's nothing then you wont be communicating with the tablet.
Your device should be connected to your computer and started in bootloader mode. On your computer you should have the command prompt for adb/fastboot open. I just go to the folder where the .exe files are located and hold shift and right click in the white space of the folder, then select "open command window here."
From here follow the erase steps: stolen from manigault! :highfive:
fastboot erase system
fastboot erase userdata
fastboot erase boot
fastboot erase recovery
fastboot erase cache
Then flash your recovery MANUALLY:
fastboot flash recovery {dir}/recovery.img
fastboot flash boot {dir}/boot.img
fastboot flash system {dir}/system.img
fastboot flash userdata {dir}/userdata.img
fastboot flash staging {dir}/blob
fastboot flash dtb {dir}/tegra124-tn8-p1761-1270-a04-e-battery.dtb
You can download whatever recovery version you wish. I downloaded 2.2.2 because that's what my device came with out of the box on Christmas 2014. It will more then likely be a .zip file. To make this whole process a little easier simply extract the files in the .zip file where the adb.exe and fastboot.exe files are located (folder should be named platform-tools) and you can completely eliminate typing the whole directory before the file name. ***After your done flashing everything you can go back and delete those files if you want. Just double check that you're deleting the right files by looking at the original zip file. Not sure if it makes a difference but I deleted them anyway.
For example the commands in fastboot will look like this exactly :
(after extracting recovery files into platform-tools folder)
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb
Note: Do NOT use the flash-all.bat command as this doesn't seem to work for this situation. Do it manually like shown above. And let each individual process complete before attempting to input another command.
After this step I didn't select continue on the bootloader. You can either select reboot or simply input "fastboot reboot" into the command window. It may take about 5 minutes to start installing everything but just be patient, it should start. Sometimes with these things you have to do things twice before it works. If for some reason it doesn't work the first time then start from the beginning and try it again. It took two times for me, but that's because I installed system.img twice and was getting double screen. Newb error... and I was a bit inebriated last night when I did this.
Hope this helps someone!
Thanks again to manigault and MidgetMob!
NVIDIA download files HERE!

i think i done the same thing
but the problem i now have is i cnt get tablet into fastboot on pc. i can load fastboot on tablet with power and volume down , but the tablet only shows as MTP device in device manager. i have downloaded drivers from nvidia and no matter what i try i cant install them i have been through all instructions but scince it went to mtp device i cant get device showing in adb. The only way i can get device showing in adb on pc ist to select apply update from adb ! but none of these commands listed in your post will work because its in sideload. is there anyway i cn reset , flash custom rom ect bu using commands while device is in adb sideload.
all i get is now send the package you want to apply to the device with "adb sideload <filename>".....
if you could shed any light on this it would be much appreciated , thanks , lester

did you update official android 6.0 before? then, not working stock recovery, stock boot...
If you can enter bootloader mode, download unofficial twrp 3.0.0.0 (here http://forum.xda-developers.com/shield-tablet/development/wip-twrp-2-8-0-1-unofficial-t2877117) and flash it.
i have a working boot.img file on marshmallow if you want.. please reply.

Sorry for the late response! I have no clue how you got into sideload??? Are you talking about through the recovery on your device? You're not able to get adb/ fastboot to recognize the device, right? It doesn't matter how you get the tablet into the bootloader. Whenever you have the phone in the bootloader then you'll use the fastboot command to "talk to" the device; i.e. "fastboot devices" without the quotes. That command should show your device if it shows as an MTP device whenever you open your "device manager" in windows. That's the same exact situation I was in. Download the codeworks from nvidia like I linked above. Hopefully then you should be able to recognize your device through the bootloader. If not DM me and I'll try to help you.

I'm having the exact problem as Lester. Tablet boots into bootloader but won't connect to computer. So I go into recovery mode and nothing works except apply update from adb. Which brings up the side load message that Lester quoted. And bootloader is showing "device=locked". I am attempting to fix this tablet for a friend that messed it up trying to flash a custom rom. Problem is he had no idea what he was doing and I'm not exactly sure what he did. I do however have a lot of experience with rooted android devices and flashing so any help would be GREATLY APPRECIATED!

Also, I've already tried flashing stock rom back onto the tablet by applying update from sd card function in the recovery but when I try to do that the tablet for some reason can't mount the sd card.

If you've got the device in bootloader then you need to use fastboot, not adb. Try the command 'fastboot devices' and see if the device id is listed. If so then grab a factory image, unzip it and use fastboot to flash the .img files using the commands 'fastboot flash system system.img'. Just make sure to match the partition names to the files.

Hello i have similar issue except when i try flash something i get this error ''remote: file write failed''
and i have to reboot into fastboot to get it flashing fully
but even though i managed to flash everything by rebooting when i boot system nothing shows up, i can just see the back light coming on and turning off after a while
Please help
