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
Hey everyone first this is a great place full of info, I just get and Trio stealth pro 7 by mach speed technology, I rooted it, I intalled CWM without problems, I also flash CM9 without any problem, but I change CPU values, to min=900MHz max=1200MHz something like that and after that a turn off the tablet then when I turn on again it just freeze in lock screen after boot. and I can't go to recovery mode with hardware bottons, Sorry for my english I'm from Venezuela. thanks any help.

You can get into recovery via ADB, Download the USB drivers for your device and then get the Android SDK tools, you can read up how to do that, then get into your platform tools folder, get a cmd prompt going, turn it on, and type "adb reboot recovery" as fast as you can before it freezes.

Don't know if you're still having the same problem but if so, you're in luck. I have the same tablet, what I did to restore mine was to download livesuit to flash a recovery image onto your device. Of course everything will be deleted but once you're back into your tablet you can put all your apps back on &/or your custom rom. I was able to get CM10 onto mine running very smoothly so I recommend iit.
Anyway, use the recovery image for the ly-f1 tablet. It's exactly like the stealth pro trio tablet so you can use the same things. Just google "ly-f1 recovery image" download a good one and open it up in livesuit. After that you're gonna wanna put your tablet into download mode.To do that you wanna make sure the tablet is off. Plug your usb in. Press and hold the volume down button on your tablet while pressing the power button about 10 times or at least until you hear your computer respond. Livesuit will guide you there rest of the way. It's really simple.
GOOD LUCK.

Hi, I'm kinda of a noob at this stuff, but I've learned quite a bit recently from just reading around, so bear with me if I don't understand or need more specific instructions. I have the trio stealth pro 7 and it is always stuck on the boot screen with the android logo when I boot. I was attempting to flash cm9 on the tablet but after I wiped the tablet initially, i couldnt find the cm9 rom on my internal memory while in recovery mode, so I ended up turning off my tablet, which now doesn't boot up anymore (stuck with android logo). I found a fix where you can use livesuite and adb to fix this issue; however, after installing adb, my tablet is not being detected, (my phone does). My tablet is not being recognized by windows in general, and it doesn't show up under device manager. There was one part of the step where I need to install usb drivers for the tablet; however, I cant find any online. I have used the tablet before with my computer before the attempt to flash cm9, so I am guessing drivers should already be installed. I feel I can get this issue fixed if I can just get adb to recognize my tablet. Perhaps this fix is not the one I need and maybe there's a simpler fix. I'm just too dumb to have realized it. Another note to add is, pressing the combination of power and volume buttons does nothing. Please help!!! thank you!!
stock images download
Hi guys ... Trio tablet Is similar or the same as Ly-F1 tablets :cyclops: these stock images will work and can be downloaded from link bekow.. make sure you download live suite first, applicable drivers (adb/fastboot) and you should be good . Follow directions accordingly and as reminder ,, :highfive: ,,, flashing / adb / sdk should only be used by advanced users who are comfortable using the SDK ADB flash tools.. . I am in no way responsible for bricked devices... Happy Flashing. :cyclops:

Hi u all!
First of all thank you for your time and sorry for my english, I speak spanish.
I have a nexus s i9023. I was using CyanogenMod 11 experimental 24042014.
I was having many problems and decided to downgrade to the stable version 10.1.2
It downloaded ok, installed all the updates, rebooted and then got stuck in the logo screen when booting.
The problem is that my nexus s has a broken the power button, it doesn't work.
As for right now the olny thing I can do is to enter the bootloader screen, but cant move throgh the options with the volume keys, it's like its stuck.
If I plug in the device when in the bootloader (fastboot mode) screen my PC doesn't recognice it, I search in the device manager but it doesn't appear.
If it helps when I plug in the battery the phone starts on in it's on.
Please, any help is appreciated.
Im really sad because I love my nexus.
Thank you!!!
Same here. Any help for us would be great. Thanks.

Seems like a driver issue. Can you try installing the drivers in a different system?
If it goes well, then use install cwm touch recovery from fastboot. You can take backup and flash new ROMs after that.
Try Nexus Root Toolkit to install drivers if you don't have access to a different system.

Don't I need to have android debugging enabled? If so, I don't think Nexus Root Toolkit will work. I flashed a ROM to my NS4g & I get boot loops. I flashed the wrong Gapps a few months ago.
I was hoping there would be a way to automatically turn android debugging on. I know it may sound dumb & also probably impossible.
Any other tips.
Tell me I'm screwed. Haha.

I disabled USB debugging. Rebooted to bootloader. Fired up 'fastboot devices' on cmd and could see my phone. This tells me that I do not need USB debugging on fastboot.
If you see an unknown device in Device Manager while in fastboot then use Universal Naked Driver to install the drivers. But since you don't, you'll need another PC to do this stuff. Once drivers are installed, you can do a 'fastboot reboot recovery' to get into recovery and fix the the problems. The first thing I advice is to flash a touch recovery. The rest is up to you.
Flash back the original soju firmware back onto your device by first using "nexus s root toolkit v.1.8.2 by wugfresh". It may take a little of your time downloading the roms and installing the drivers but trust me it should be working and your phone will boot into stock android 4.1.2. You can then root your device and install custom recovery as normal. Anything do pm me :laugh: ps, click the bricked option one the software is loaded up and remember to connect your device only and remove other phones from your computer
Hello XDA member
I have a touchlet xa100 tablet running Android 4.4.2 and want to root it, but Towelroot said "device not supported" and I cant use a pc because i have no adb driver for it. After searching, I tried a guide to modify the google usb driver, but that didnt work either.
My computer is running Windows7 x64 and other devices (Samsung Galaxy Y GT-S5360 and Sony Xperia M C1905) are detected by adb decives.
I hope you can point me to the right point.

I didn't find any report of workign root for your device on xda.
But you can try the most popular and generic rootng methods:
How to Root Any Device
How To Root Any Android Device
[TOOL] Rootx 2.2 (Rev 3 )- Root almost all android devices
[UNIVERSAL GUIDE] Root Any Android Device Manually !
Root any Android device (without pc n in one click)
[ROOT] Framaroot, a one-click apk to root some devices
...
BTW, on some devices, TowelRoot only works on an older firmware/kernel version. So if nothing else works and you know how to downgrade to an older firmware version, you might try TowelRoot again.
Good luck !
After trieng all those methods, i got superuser installed but root not useable, SuperSU cant uninstall/update the su binary, so i gave up.
From fun and trieng to find out if i could use fastboot i typed adb reboot bootloader, 10 seconds after the tablet gave up and isnt booting any more. Its stuck in the kernel splash Image.
Its detected by my pc as "Samsung Android Phone" but not by adb.
You know a trick to revive it from the death (except JTAG) or do i have a new paperweight?
I dont know if it has a recovery, but even if it has one, how can i get there? It has only 2 Buttons, Power and Back, and if i press those 2 together, the kernel splash Image appears.

Oh no ... sorry to hear that.
You can ask in the General discussion > Questions and Answers forum.
Hopefully someone knows a "trick" :fingers-crossed:
Thread closed and thank you.
Hey guys, today I'm back with another root guide. Of course it also shows you how to install recovery in case you don't have it. I will try to make the guide as easy to understand as possible, you know, for noobs. It's going to be a long day.
First thing, you can get any SuperSU zip that you want from Chainfire. I have the guaranteed one that I used to root mine. It depends on you. I will give you both links to Chainfire's thread and my file.
Requirements
-A PC
-Your device with USB cable(its battery level would better NOT below 30%)
-A stable internet connection
-Your brain(it can blow up, man, seriously)
A warning before we start:
-Files you download on your PC:
+Drivers
+Odin+Recovery
-Files you download to your device: Root(Chainfire's or mine)
Download all of them before you do anything. Extract Odin and recovery
The drivers are for Windows. I don't know if there are Samsung USB drivers for Mac or not.
Main Guide
1. Enable USB debugging on your device in developer options(to enable dev options, go to about phone, rapidly tap build number until it says that you have enabled it)
2. Open the drivers setup and install it on your PC.
3. Boot to Download mode on your device(Power off your device, then hold power and volume down button. When there's a triangle, press volume up.)
4.Connect your device to your PC via USB cable.
5.Run Odin on your PC
6.Uncheck Auto Reboot, click PDA and choose the recovery file.
7.Hit Start and wait until there's a PASS sign. Plug out your device and hold power button afterwards.
8.Hold power and volume up button to boot into recovery mode.
9.Tap Install, go to the folder where you put the root file in, then tap the root file.
10.Swipe to falsh.
11.Reboot, download Root Checker to verify
ENJOY!

Well, I tested it on the 8 or 9 inch whatever and it worked out. But there's a still chance that this won't work on models other than its own. You can check and send me your device's model and i'll figure out another way for you. But don't try this method, it will only make it worse.

Ok, you should try the other root zip file, because I posted 2 to make sure that you can do it all over again. Or you should first try rebooting your device again. I'm sorry for the inconvenience
