[Q] Nexus S - can't mount anything! - stuck on Google Logo

Hello!
Okay, so the weirdest thing has happened with me. My Nexus S (i9023) was working absolutely fine till last evening when it ran out of battery. After I came back home, I put it for charging and switched it on.
For the first few time, nothing would show except the USB connected/ disconnected screen which appears everytime you plug your phone in. I thought maybe it was just being weird, so I took out the battery and booted it up again. This time I am just stuck at the Google Logo! It is not going ahead.
I can enter CWM Recovery. However, I cannot mount sd card or usb storage or anything for that matter. If I try and install through .zip it says 'e can't mount sd card'. I can't format my sd card either, same problem of can't mount. I thought if I tried pushing a ROM in by ADB that might work.. It did transfer the file it showed that in the cmd window. However, CWM refuses to mount my sd card or my usb storage.
So basically, in essence, I'm locked out of my Nexus! Please please help. I'm really lost and confused now.
Thanks so much.
Alex

Similar problems below in this thread with solutions.
Let your phone sit for an hour with the battery out, Download Wug's Nexus Toolkit from the development section, download drivers from there and install stock boot img then re-root.
I have never seen it before but seems like this prob is coming up a lot lately. It can be fixed. Good luck.

Thanks for your reply. I'm starting now. I have a doubt, how do I install stock? Since I can't seem to be able to mount anything..
"It can be fixed" - few words have given me this much hope in my life! Thanks a lot!
EDIT: I guess you mean flash through ADB right? Okay, let me try that. I really hope you are right. Some of those other problems lead to paying up! Ouch.

Hey! I just tried using WUGS.. for some reason it does not make the final boot and instead says: 'Fastboot Status - FAILWrite Fail' -- oh god.. I'm trying it again now..
Is there any other way out? :/

Okay, so now my recovery is also gone after using WUGS.. oh man. And the phone isn't starting up. Please please please help? I'm getting really desperate now.
EDIT: And it sucks that I can't post in the WUGS thread (http://forum.xda-developers.com/showthread.php?t=1766475) because I have less than 10 posts! fml.

can you boot into fastboot? If so then itnwasnthe same prob I had when I wiped my phone and SD in recovery. If you can boot into fastbootnthen makensurenyou leave the batt out format least an hour. If you installed Wug's drivers the bottom left corner ofnfastboot should give a message.

Yes, I can get into fastboot - i'm leaving the battery out now - do you think i should try
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
and then flash everything again?
There is always a way to recover the nexus right? Even if it is hardbricked, right?
I really really appreciate your help.

I too have this problem but after a lot of battery pulls it does eventually start up. It just started happening all of a sudden. Ive heard that heating it up with a hair dryer or heatgun can help and also re-locking and un-locking the boot loader can help as it wipes the card. Could be worth a try.

Any luck Someone? I know it sux big time to feel like your phone is bricked. I am not a dev or expert but it sounds like the prob I had last week, when I posted no one replied so I ordered a GNex thinking all was lost. Before I activated my new phone I felt like I had to fix my nexus before getting started on my new phone and that's my situation. I don't want you to feel like the community has forgot you and thats why I'm trying to help. Were you able to get Wug's Toolkit to recognize your phone after leaving the batt out? I don't know why but I think that's the key. I had to leave mine overnight 'cause I don't have a PC and the next day at my friends house when I plugged the USB in I got that message at the bottom of fast boot "system normal" or something to that effect. Once recognized the stock boot IMG is what you need.
ANY ONE ELSE WHO HAS HAD THIS OR A SIMILAR ISSUE PLEASE GIVE SOME ADVICE. LET'S NOT LEAVE A COMMUNITY MEMBER WITH A LIFELESS PIECE IF PLASTIC. THANKS FORUM.
To set your mind at ease yes, I believe as long ad you have access to fastboot your nexus can be saved.

sounds to me like a hardware issue, since you haven't changed software and it seems like a brick. try flashing stock rom via fastboot, you should be able to google around how you can do that.

Hi, if I'm not wrong essentially what WUG does automatically is what you do by fastboot (erase bootloader, cache, system.. and then flash all of them back) in both system fails to wipe and refuses to be flashed again (flashwrite error).
I don't want to lock it and then unlock it again because I read in other threads that it might lead to a permanent lock with an error for subsequent unlocking - that would leave me completely out.
Anyway, let's see - I've given it to someone to check it up. I'll keep you guys posted. He said he wanted to repartition the sd card.
My intuition says: hardware problem!

So I tried Odin today - and that also did not work it refused to flash the ROM. In the process I somehow managed to mess up the bootloader such that the phone would have some two lights on randomly when I switch on. It doesn't go into download mode either. I next plan to use JTAG to get the bootloader back and then reflash everything. Hopefully, that should sort things out. The Resurrection tool is amazing! I'll keep you guys posted.

Get it going someone?

I have the same problem as you, with the added difficulty of my phone not being recognized by anything other than fastboot. No ADB commands will function. It was charging, rebooted itself into a bootloop, and I have been struggling with it ever since. It is currently a worthless piece of plastic, my favorite phone ever, gone.
I can wipe and re-write recovery all that I want, but it seems as if the sdcard partition that /system and some other stuff writes too is either corrupted or physically damaged. Every time I flash it all via fastboot it all goes as stated, but gives me a fail message on the last two partitions and never allows me to actually write a new ROM or boot image. I wanted to try ODIN but can't seem to get it to recognize my phone in download mode...
Let me know if you have any success or progress!

Hey Nexism! Sorry for the late reply - things've been busy.
The JTAG is giving an internal voltage for some reason - so I've sent it for repair. It'll be repaired by tomorrow or so.. I'm then going to set it back up. It's all already soldered and all, just waiting for the JTAG. I think I've understood how this thing works now. So yeah, I'm hoping it's all sorted. Thanks a lot for your concern man.

Well my phone went blank - no fastboot mode - no download mode - no nothing - when i'd put the battery in randomly two of the four front lights would come on.. JTAG is going to solve the problem hopefully.

So ladies and gentleman, JTAG also failed - apparently something was wrong with the sd card only. I got my motherboard replaced - luckily the guy I went to knew someone and Samsung and charged me Rs. 4,000 as opposed to the Rs. 8500 quoted by the Samsung Service Centre. Oh well.
Back on my Nexus now. XD

I am with the same problem here... I cant turn off my phone or it get stuck in pre-boot phase. Acess recovery and cant mout sd card. Using last stable cm 10.
I think my sdcar is dead.

Same problem here. Around 8 out of 10 times I get stuck on the Google logo, 8 out of 10 times in recovery I can't mount SD card as well. And if I successfully boot, Media wakelocks and my battery drains in sleep as fast as if the screen were on. Please help.

For me I first noticed that my apps weren't using the SD partition. Tried to mount normally (fully loaded ROM) (ROM is SlimBean Beta2), but it would not mount. Went into CWM and tried to mount in there, but it would not work. tried to "Format /sdcard" but "Error mounting /sdcard". My phone still boots and runs fine, but I just don't have access to the SD partition. I don't want to do anything because I need my phone for business. Is there any PROVEN way to fix this yet?

[Q] Random rebooting does not stop

Hi
This is a well known issue with the nexus 5. My device permanently starts rebooting. The google Logo occurs and then it rebotos again. There is no start animation. If I press the power and volume down bottom I just see the bootloader screen and after half a second it reboots. I can't do anything.
My phone is rooted (no custom ROM) and before I go back to the shop I want to unroot it. However, with this behaviour I'm not able to do it, or is there any chance? Does someone know at least, how I can boot normaly to unroot it.
thanks for your help

Hello, take a look at this thread http://forum.xda-developers.com/showthread.php?t=2513701

Is this really a well known issue? What were you doing directly beforehand? What have you tried to do to fix it? Have you tried using fastboot commands to reload factory images? Are you a toolkit only user? Have you tried a factory image through that?

Well IMHO it is a well known issue (see for example the wikipedia page or just have a look in tech forums). Directly before, I was writing an SMS and put it in my pocket (everything seems fine at that moment). 10 minutes later I just want to check my SMS and then it was already rebooting all the time. This was not the first time, I had this issue 2 todays before, but after approximatley 20 reboots it started correctly.
So far I was not able to use fastboot commands, since I can't enter fastboot. I didn't use a toolkit.

I have never heard of the issue where it was only rooted and it just randomly decides to reboot and keeps doing it for no reason at all without the user flashing something that it did not like. So are you saying that you cannot even turn the phone off it just keeps going into a bootloop and trying to enter fastboot does nothing?
I don't think this is a really well known issue.. Have not seen to many support threads about this.

If the wall charger is plugged into the phone, the nexus just starts rebooting. I see the white Google logo and after one or two seconds it reboots. Sometimes you see the boot animation (4 circles) but after a short time it restarts the phone not able get to the point where you unlock the SIM. Trying to get into fastboot mode is also not possible. The fastboot mode appears but after half a second the phone reboots again. If the nexus is not connected to a charger it repeats rebooting for about four times after that just a black screen appears. If I'm not able to get into fastboot mode I can't unroot the phone, right? So the links you shared are not useful in my case
I have the nexus now over a week and the phone worked perfectly fine the first week.
I have uploaded two films of the problem to youtube, see this link. One film is with the nexus plugged into the chrager and one where it isn't.

That is very strange.
I would definitely use Madpiercing's post and link to http://forum.xda-developers.com/showthread.php?t=2521691&page=3 to try and fix it.

The very strange thing is, that it worked well over a week. the random rebooting starts two days ago, first time it starts again correctly after 5 min. Now it seems to hang in a loop.

After a while I was able to get into the fastboot mode: I plugged my nexus into the wall charger for about 1 hour. Then it booted correctly. I had plugged my nexus into the charger before (over night) without leading to the same result. It seems that it just starts working correctly as random as it crashes
Do you think it is a bug in the bootloader or that something happened while to rooting the phone?

Nexus 5 soft bricked after installing the wrong kernel

So i have a big problem, i acidentally downloaded the wrong kernel for my Nexus 5 (acidenttly got the nexus 4 versionb of Hells-core instead of the N5 version.) and flashed it, Now my phone wont boot nor can i access recovery or the bootloader. BUT when i plug it into my computer it tries to install drivers but fails because it cant find them, So im pretty sure its not a paper weight. Im running windows xp and was using carbon. If ANYONE can help please let me know.

i managed to get it into recovery as well as fastboot. but now when i try to do my recovery backup it causes the same error i was having i.e it would be detected by my laptop but i cant see anything. i may have to do a complete factory restore and see what happenes. Its kinda sad my GF with really NO android experience helped me get it into bootloader WHICH for anyone that has an issue similar to mine where your PC detects your device but you cant see anything on the screen hold down both up and down + power to get into bootloader. if it doesnt work at first hold down down + power (while its still connected to your pc so you can hear it feject) as soon as you hear the eject noise press and up down+up+power and you will be in bootloader

This guy had the same problem

He dd'd his messed up partition back. I guess it's the bootloader that was overwritten but you can dd the secondary bootloader to the primary bootloader partition and it'd fix it hopefully.

[Q] DAMN IT! Deleted everything - NO OS Installed

So I was going to reinstall Cataclysm ROM because it has been giving me problems the last few days, mainly it's been dropping my WiFi signal forcing me to switch it on and off just to use my phone, like once every minute
So I downloaded the file to my device, and went to flash it, but I wiped the dalvik and cache, and I pressed data I'm pretty sure, 100% by accident cuz I was so mad at my WiFi signal constantly dropping
Anyways now my phone says "No OS Installed, are you sure you want to reboot?"
I just did a few hours worth of research and... nothing seems to work
I've tried a few ADB sideload guides but I can't seem to follow what they're saying since my screen shows something completely different than what theirs shows
I checked a couple forums too and no one else was experiencing what I am
So I've come to you guys to help D:
Basically I have TWRP installed, my computer doesn't recognize the device when I use the flashall.bat in Windows, so I tried a few different cables, same thing
Any other ideas?
I saw the USB OTG method works, should I just buy one of those and try it out?
It's just like an add on hard drive that I'll load the ROM onto right?
Do I have to flash the stock img or can I flash a new ROM, like Cataclysm again, or Carbon or something?

I'm going to go buy one of those USB OTG drives, a Kingston 32 or 64gb one from Canada Computers
#fingerscrossed it works guys!
If you have anything else for me to try let me know!

Flashall.bat, which uses the program fastboot, isnt meant to be used with a recovery (in this case, TWRP). It is to be used on the bootloader.

If it did not work there, it must have been a missing driver issue. Or your fastboot setup.

Got it working last night, since I couldn't do it using TWRP or CMD
I just used Wugs Toolkit, selected the bricked / bootloop option, and flashed stock + unrooted it
Loaded the newest imgs available, so I'm good for now
I'll wait a bit, see if the WiFi thing comes back on stock, if not then it was probably something to do with Cataclysm, I didn't even save any logs to hard to see what it was
Thanks for all your help though!

It didn't work because you didn't install the drivers for adb/fastboot properly. Anyhow nice to see your device is working again!

thank you so much for your help.somehow i got it back up and running

Had the same happen to me. It didn't want to go into recovery gave a message it failed. With some patience I manged to get the button combo to work for fastboot then did a flash-all of the factory image. I think the trick was it had to be plugged in to get to download mode and I think you may hit the power button slightly before the volume down. It was a bit tedious. I tried to recover the boot.img and that trashed things up worse, got no google loading logo or something odd. Anyhow flashing the full factory image fixed things!
Glad you got it resolved, maybe this helps someone else in the same spot.
