[Q] NS4G Not recognised - Nexus S Q&A, Help & Troubleshooting

Hi all,
I've got a Nexus S 4G CDMA Sprint phone running Stock ICS 4.0.4 IMM76D.
My bootloader is unlocked from previous roots and whatnot.
My problem is that my phone is not being recognized by my computer at all. We're talking complete nonrecognition. No yellow triangle in device manager, no pop-ups, nothing. This phone will just not be read by my computer! I've tried different cords, different computers, re-installation of drivers after resetting my computer, installed PDA net, did a factory reset on the phone, I've literally been on Google for hours upon hours upon hours trying to figure this out and can't figure out why the computer is not recognizing the phone and why the phone is not allowing me to put it into usb mounting. It is however, charging via the computer and wall plug. I can get into stock 3e android recovery, fastboot using V-Up and Power and I can get it into download mode. It is NOT recognized in any modes by the computer nor other computers including my Linux box. The phone states that the usb control initializes but then ends a moment later. I am thinking this is a hardware issue but that leaves me with two issues:
If I was to go to Sprint to have it fixed they would realize my bootloader was unlocked thus voiding the warranty and I'd feel like quite an idiot at the store
If it is hardware related why is the charge working on the device.
I have also tried to bend up the usb plate to make it touch the pins better but that did not help at all. I am at my wits end and really need some help here, I've done everything I could find on Google and here plus more. I want to just return it but with the bootloader unlocked this is really not a possibility. I am looking for help to either become able to lock the bootloader without it having to be connected via the computer so I can then get it fixed if it is hardware related or if I can get the darn thing to be read by the computer once more. so yea, this is where I am at and I would appreciate it so much if someone could help me out, thanks guys!!!

Wireless adb in playstore should help.

That would be perfect! Only problem is that it requires root access on the phone which I am unable to obtain because I cannot access the phone. Is there a way to root the phone without having to connect it via the computer? Something like an update.zip with files able to be flashed through android recovery 3e? If I can get root access than wireless adb would be perfect.
*ultimately if I could remove signature checking in Android Recovery 3e that would work so I could in turn try to root the phone and install a different recovery to then try a different rom to see if that in turn fixes the issue.

You might be able to download your rom of choice and rename it update.zip. I'm not sure if it will flash though....someone else chime in if I'm wrong. You can use wireless file transfer if needed.

Yea I've tried that, everything gets shot down by the recovery with a E:Signature Verification Failed. Thank you for your help so far but I don't think this is something that is going to be helped. I've put in a ticket to Samsung for a repair under it's warranty. In the past I've sent in a rooted phone and they've fixed it so I think I'm going to give that a shot. Just don't want to be without a phone for 2+ weeks.

Well good luck...you are running stock unrooted so it shouldn't matter. It is a dev phone for damn sake. Sorry couldn't help.

Well if you want to download a custom rom... Since you are on this forum. Download any rom (preferably CM9 since its quite good from my experience). Flash the stable version and wait till everything is completed. Now when you flash make sure you download a recovery...eg ClockWorkMod Recovery from google market. You should now have a custom rom installed and download wireless adb as chappy said. See if that works

[Q][NS4G] Problem with fastboot and fixing phone.

Hello, I recently decided to root my phone and place Cyanogenmod on it. When I did that I realized my radio was no longer working. In an attempt to just get back to a working phone for the time being I flashed a rom that I believe was just for the Nexus S and not Nexus S 4G. Due to my stupidity I am unable to communicate from the device to my computer using USB. When I attach the device to the computer nothing happens. The device does not even appear in the device manager. I have tried on multiple computers as well. On top of that the rom seems to have put me back into the stock recovery. If anyone could help me figure out just how to get USB working again I would be very appreciative.
I should note that I can still transfer files to the phone using the sd card or via ftp.
Thank you for your time and help.
Change the USB cable?
Yes, forgot to mention that. I have tried 2 cables both of which work on other devices.
What if you hold in the middle of the volume buttons (i.e. both up and down at the same time) and keep holding, then plug in to your usb port? It should come up as download mode. If it will do that you might try using Odin.
Or try a different machine perhaps?
are the drivers the same for the S as the 4g?
do you have clockwork on the phone or have you tried to run recover by holding volume up and power?
just throwing things out.
Hello, I appreciate any and all suggestions and help.
I have Odin downloaded and installed, but the computer can not find the device so Odin can not do what it needs to do. This is even the case in download mode.
In terms of recovery I am on the stock recovery. I was on clockwork but made a small mistake and now am back to stock.
I know if I can just get the computer to see the phone exists I can fix it.
If you can find the full OTA package for NS4G, you can try putting it on the SD card and flash it via stock recovery.
Also another thing worth trying is connecting the phone to an Ubuntu machine and see if it's detected or not.
I have tried looking for the original full OS. I will continue looking, but the different OS thing is a good idea I did not think of. I will attempt that now. Thank you.
I installed Ubuntu and the Android SDK and Ubuntu was unable to see the phone as well. I am going to keep searching for the original firmware to see if that will fix it. Thank you for your help so far, it is greatly appreciated.
I have found the only rom my phone will accept now is
Android 2.3.4/GRJ22/KRKC1 Radio/KA3 Bootloader
Which is for the M200 variant. This apparently the Korean version.

[Q] Stock (unrooted, untampered) Nexus S stuck @ Google screen during bootup

Hi folks. I've tried searching on this subject and looks like every thread I've seen on this site related to a stuck Google screen was the result of trying to root the device. My situation is different. I have a stock phone given to me by Google (I'm a former Googler) and up until recently the phone started to go awry whenever I had to reboot it. It would stay stuck at the Google logo. I've tried recover, clearing the cache and also factory wipe and it will always restart and get stuck at the logo. I've found some threads on Google's support forums that mention it may be hardware related with faulty memory being the issue. I'm trying here as a last resort.
The phone is the regular Nexus S 3G for Tmobile. Please help before I smash this phone into the wall.
I'd try rooting and installing a custom rom. If it works after that and you want it to be stock again you could just reverse the process. If none of that works then I'm guessing it's similar to the other phones with hardware problems.

I can't seem to root it. I've installed the adb drivers and windows detects it whenever I plug the USB in, but I can't unlock it to root it. When I run this command, "fastboot oem unlock" it just keeps trying to detect the phone but never does. I think it's because USB debugging isn't enabled and I can't enable it without being able to get back into the phone.

you need the nexus s drivers go to the pdanet website http://junefabrics.com/android/ and download and install the free version on your desktop. then follow the on screen instructions and it will install the drivers for you. thats the easiest way to install the drivers.

I've already installed that. It won't detect the phone properly because I can't enable the USB thing within the android OS since I'm blocked from fully loading up the phone.
It sounds like the sdcard memory won't mount. This is a hardware issue.

That's interesting you say that because I do notice an error during recovery and selecting data wipe. I had a colleague in the android dept tell me it's most likely bad flash memory.
"E:format_volume: make_extf4fs failed on /dev/block/platform/s3c-sdhci.0/by-name/userdata"
I'm gonna call Samsung tomorrow.

[NEED HELP URGENT] relock bootloader nexus s without usb connection

ok so i really need some help with this, here's the problem:
My nexus s won't charge or either be recognized by the computer so i've had to charge it with the core cables of the charger connecting the red to the + and the black to the - anyways i need to return my phone to wind but my phone is rooted and they won't accept it so i really need help to relock the bootloader without using my computer because it won't recognize it any suggestions please?
You're out of luck... Unless you used gingerbreak, which I'm not sure if it works either, you need to use computer to unroot your phone... Have you tried another cable maybe?
Sent from my Nexus S using XDA App
yes i try 4 different ones none of them worked
You can unroot it no problem. What you can't do is relock the bootloader.
ye figured that out (after runing again the update to ICS) i guess ill stay with my phone like this now.. Now quick qestion is it possiible to root it again? haha rom manager is not flashing the Clockworkmod :S
You would need a computer to root now. Should have flashed su after you flashed the update.
guess im completly f*cked now, all i want is to restore to where i had my apps.. is that possible?
I had the same charging problem, but realised that it was charging it just doesn't say it anywhere.
The only place it tells you that it's charging is under setting > battery.
I thought my phone was gone too, but just try plugging it in and going into the settings and it might say charging
You can still root, assuming you have a non-stock recovery. Otherwise you may be out of luck.
im trying to find out how to have recovery or restore my phone on different way (not using a pc) rom manager keeps giving an error that it doesnt have permission so i cant flash recovery from ROM Manager
You can't.
so theres no way to make ROM manager work either?
You need to be rooted to flash a recovery with rom manager. Which you are not. You are stuck there .
yeh well after trying everything cant do Sh*t about it im stuck with this phone can't do much now just the basics

Return to stock help

Hoping to get some direction or assistance here.
I need to send my SGS3 back to Verizon for a faulty USB (intermittent charging)
I was rooted with stock ROM, but I factory reset and now not rooted so Mobile ODIN doesn't work, and Voodoo says I am rooted, Root Checker says I am not.
When the device is connected to the Windows 7 PC, it often comes up "Device not recognized". But when it does connect, no folders or access to internals show up. Odin doesn't show connected, Root Tool Kit won't show it in Debugging mode.
Interesting too that although that is happening, when I click the "eject devices" it shows as SCH-i535 in that menu, but when it is in Download mode, it shows up as MSM8960 as the device connected. The only two things that show I messed with the phone are the CUSTOM padlock on boot screen and in ABOUT PHONE it shows as Modified (could I chance it?).
Any suggestions on how I may be able to get Odin on PC to connect, or to somehow get the root to work again so I can use Mobile Odin? Oh, and Kies doesn't work via USB, but does over WiFi.
Thanks.
Looks like I am going to have to try to connect adb over sshdroid. Anyone ever do this? Also, has anyone used a manual root method?
Alright, so SSH isn't helping, anything I can us the stock recovery to work around this? Please help, I need to get this back to stock with the week. Thanks
Success. Somehow, z4root was able to temp root for me after 2 hours of nothing. Used Mobile ODIN and back to 4.0.4 with no padlock and everything official. Mods may close this.
Nice job!

[Q] LG optimus pro G bricked after using exitrecovery.zip

hello,
I hope someone can help me with my AT&T LG Optimus Pro G phone, which I have royally screwed up.
I was experimenting with the cyogen mod and after installation I installed the freegee app and once the cwm recovery was installed, I decided to go into the recovery by holding down up volume and power button.
Once I was in recovery for CWM i couldn't exit out, and the phone constantly booted into recovery after every reboot, even if i took out the battery, and powered it on.
I tried reflashing the cynogen mod through the sd card, and even though I would get success message the phone would still reboot into the cwm recovery.
I started doing research on the internet and i found file exitrecovery.zip that could be used to possibly get the phone out of the cwm recovery.
After installing exitrecovery.zip, I rebooted the phone, and now I have complete black screen. There are no light, no hints the phone is even turning on, and I can't get into recovery( or at least I can't tell). The only thing now is that when i connect the phone to the computer the window tries to install drivers for the device, and eventually prompts to insert a CD for LG drivers. I already have LGUnitedMobileDriver v.3.10.1 connection drivers installed from their website.
Please help, I am really stuck here..... and have no clue what to do. I am fairly new with rooting and modding, and I am extremely miserable.
The phone is still under warranty from LG. Anyone if all else fails, and since the phone has no screen or lights, whether they would replace it?
Attaching the exitrecovery.zip that I used.
sobbing....

hi, thanks for your reply. Again I very much new to the rooting and android OS tinkering, and nowhere close to an experienced user.
I tried to use google with your information in regards to how to use flow ROM with expansion.exe, but did not get any leads.
I would appreciate if you could elaborate more on this process.
When my phone is connect to the computer via usb is is constantly trying to install drivers. I had already installed LG usb connection drivers in the past and it was successful. It almost seems it tries to install driver yet fails after receiving no input from the phone, and then request LG CD with drivers.

Try to find driver on the web-site of producer. Set them. Overload a vehicle in Bootloader. In the controller of devices on компе must be determined your device. Then on a computer start sewing - .EXE.
Did you get this problem resolved? I have the exact problem with the exact phone!!!
thank you very much
