Sprint Gnex: Help! Can't unlock bootloader, root or flash roms, phone not detected!

Hey guys I am having a very annoying issue with my Sprint Gnex. It runs the latest OTA (I believe 4.1.1) and is not unlocked or rooted.
Well, I want to unlock it, and so I try following this guide:
http://www.droid-life.com/2011/12/05/how-to-unlock-the-galaxy-nexus-bootloader/
I have the latest drivers from Samsung installed on my PC. What happens is that whenever the phone is in recovery mode, it is not properly detected by my computer, and in device manager, it has a yellow exclamation mark next to it. When I am running the phone normally with USB debugging enabled, it works fine. Just not in recovery mode.
As a result, I can't run the "fastboot oem unlock" command! Essentially, I can't do anything with the phone! Can anybody help or knows what might be going on? Again, when the phone booted normally, it is detected by my computer and adb commands work fine. Just not when it is in recovery mode!

First, of course it's your fault. Who else's would it be?
A tip for you: When you get that yellow exclamation mark when connected in recovery, you need to manually update the driver.
Another tip for you: naked drivers, you don't need any of that Samsung crap
And the last one: normal ADB mode doesn't work in stock recovery, only ADB sideload.
Okay, this is really the last one: if you had EVEN browsed this forum and read the stickies, you would have known that to unlock your device, you need to be in fastboot mode, not recovery mode, 2 different things, and you can get there by.. Searching.

Where do I get the driver to manually update? And sideload didn't work either, I tried using it to install the 4.2 official ROM, but it wouldn't detect the phone

I've edited my previous post. Where do you get the driver? Where did you install it to? Search for naked drivers in Dev section.

You know what? Piss off. I was tired when I posted this thread, and looks like I had some of my terminology mixed up. When I was in recovery trying to flash GA02, adb sideload IS what I was using. The drivers I got from Samsung simply didn't work. If you are trying to suggest that it should have occurred to me that "Hey, seems like the official drivers don't work for what they are designed to do. Obviously I need hacked ones" then you are out of your mind.
In fact, it turns out that the Universal Naked Drivers you referenced did the trick perfectly, which I do appreciate. Right now, that is aside the point however.
On to the terminology mixup. It turns out when I was trying to unlock the device I WAS in the fastboot menu, not recovery. I was not aware of the naming distinction, but I WAS in the right place, and it still didn't work. Presumably due to the Samsung drivers, which were apparently the source of all the problems I've been having.
Again, I appreciate you pointing me in the direction of the Naked drivers, but I take serious issue with condescending attitude that so many people have on XDA.

[ISSUE] Problem with rooting

Hello everyone
Got Nexus 7 (2013) few days ago and now tried to root manually (from this thread: http://forum.xda-developers.com/showthread.php?t=2382051)
and everything was fine untill I tried to flash TWRP in command (fastboot flash recovery recovery-twrp.img) and flashing didn't end, had to close cmd or unplug USB to stop it, once unplugged it said "Too many links" or something like that, tried doing it bunch of times with older versions and what not, nothing worked.
Then found out about Nexus Root Toolkit by WugFresh and again, everything was fine, drivers checked and working, but once it got to the spot where it had to boot .img file it just never ended, as seen on tutorial videos it takes about half a second to load it, I waited for 10 minutes but nothing.
This part - http://imgur.com/QU5Ic0R
So I guess its something wrong with transfering files to Nexus 7 ? Even tho I was able to import few files to it before. Maybe something on my PC is blocking it ? :silly:
Frustrated and exhausted Would appreciate any help, Im new at android stuff so please detailed answers
Thanks.

$50 REWARD for unbricking my brand new Nexus 5x

I will send you $50 via paypal if you can either instruct me how to fix it, or if i can mail you the phone and you return it back to me in working order.
I just got the phone. And i have spent the whole weekend reading and following what others have suggested in this forum to no avail.
I wanted to install TWRP onto it. I followed the instruction to unlock the bootloader first int the dev settings, then in the fastboot screen. When i unlocked it i got the yellow triangle, telling me to relock it, that the system cannot check for corruption, etc. It would not move past this screen. I had to reboot. It would not enter any recovery.
I tried flashing back the stock recovery from fastboot, from the stock images, i would not go past this screen. It would not boot into the system.
I then went to try to get back to stock with the instructions from this thread:
http://forum.xda-developers.com/nexus-5x/help/req-help-to-unbrick-t3251740
Phone will not boot, it hangs at the "google" start screen. I can not unlock bootloader from fastboot now. It gives a "DENIED" message, unable to oem unlock bootloader.
In a windows machine, the phone will not be recognized. Under device manager, its listed under 'other devices' as 'android' and the driver fails to load. Under download mode, the LG drivers will work. I can only get in download mode on a Windows machine. I can only get to fastboot on a MacOS machine through terminal.
Please help, i am going to throw this phone in the trash otherwise. I will answer any questions you may have that will help solve this.

Turn on your windows machine
Download the tool in this link http://forum.xda-developers.com/nexus-5x/development/toolkit-wugs-nexus-root-toolkit-v2-1-0-t3258492
Put your phone in download mode
Open the tool, click on the home button "Flash stock + unroot" and check the box under it that says "bricked"
Problem solved

since you have installed TWRP do as written HERE.
It is confirmed that is working for nexus 5x too, read the whole thread anyway!

Wug's may work for you. It may not. I've used it since its inception but have found issues with it off and on. As far as drivers go, my Windows 10 machine seems to have issues since last few updates. So far, (I have a rooted N5, N9, and complete stock 5X) updating the drivers through device manager has worked every time. Choose update from on drivers on PC then run through update on both drivers shown under android interface (or similar). Be sure the device is awake and connected when updating, of course.

Thank you, i will take you up on that offer.
This is the only thing that comes up when i connect via fastboot, this and a drivers not installed alert. I CAN NOT install them manually, the dialog just says the Windows could not find the drivers.

Issue resolved. Mods can remove this thread.

[Softbrick] Every ROM stuck in Bootloop

Hello,
I really dont know what to do anymore.
No matter which ROM I flash, I always get stuck in a bootloop. I always wait 20-25 for a boot, but it doesnt pass the bootanimation.
Here is what happened:
My PC didnt recognize my phone anymore even though I didnt change any driver settings or something like that. Same with other PCs, not even showing up in device manager at all. So I thought I messed up some settings in my phone, thats why I wiped data, system, cache, internal store, then pushed a new ROM to my phone via USB OTG, but it doesnt boot at all. Phone still doesnt get recognized by any pc, not even in TWRP or bootloader.
Here are the things I tried so far:
- Ressurrection Remix (latest 3 versions) with OpenGapps
- Lineage OS with DynamicGapps
- both of them without any gapps
- OMNI Rom with DynamicGapps
I also did a factory reset before every flash. After 20 minutes of bootloop I also tried a 2nd boot for 20 minutes...nothing.
Since I cant access my phone from PC I cant flash stock ROM (or is it possible to flash it via TWRP?). I guess I just wiped something that I shouldnt have wiped. Does anyone have an idea what else I could try?

I had something similar happen to my 5x a while back. After fiddling with drivers/device manager etc, I found this on net which actually worked for me:
Solution 5 – Uninstall Android drivers if PC not recognizing phone
Sometimes you might not have the latest drivers, or your drivers might not be properly installed, so in order to fix issues with Android devices and Windows 10, it’s advised that you uninstall your Android drivers. To do so, follow these steps:
Connect your Android device to your computer and open Device Manager.
In Device Manager locate your Android device. Usually it’s located in Other Devices or in Portable devices section, but the location might be different on your computer.
Right click the device and choose Uninstall.
uninstall-driver
After the drivers have been uninstalled, disconnect your Android device.
Reconnect it again, and wait for Windows 10 to install its drivers again.
Check if your Android device is now recognized.

Above post fixed my driver/PC not recognizing phone issue. As far as your bootloop issue, I'm assuming your bootloader is still unlocked, right? If so, and if above fix works where PC recognizes phone, try flashing google factory images via fastboot commands.

Since it doesnt show up in device manager, I cant uninstall the driver there.
I also tried it on a new PC that did never get in touch with an android phone - nothing. Not even a sound when I plug it in. The phone is just charging, thats it.

Have you tried using a different cable?

Yeah I always used that tool in the past. But since my PC doesnt recognize the phone at all, not even in fastboot mode, that doesnt help me. I really need a solution that works just with TWRP...
Edit: Just an idea from my side. Would it work if someone, who just cleaned flashed, makes an nandroid backup, which I just restore with TWRP?

what radio at you installed? 7.1.1 02.2017 for TWRP

sorry, I have inattentively read the previous post. redownload zip if doesn't help, then your recovery is damaged and it is necessary to look for a way to connect him to PC

Problem solved. Got a new USB cable today, it worked now. Flashed stock image, it finally booted.
But wow, the old cable is already broken after 3 months...well it still charges very fast, but thats it.

Totally Stumped

I've tried everything in my power to unlock this bootloader, and nothing is working. I've tried several different drivers by using device manager and selecting them, and all of them seem to allow my device to be recognized until I boot into fastboot. Then I get <waiting for any device> and nothing happens. I've updated my Android SDK to 8.0, as 8.1.0 won't install due to a mismatch of file sizes. My Pixel C is on 8.0. Any help would be much appreciated! Thank you

Thank you for your reply! I actually just figured it out in the meantime. What I did was update the drivers WHILE in fastboot, and ADB finally recognized my device. I was then able to unlock my bootloader!
