Hey guys, i've a big problem.
Yesterday, suddently my nexus s didn't boot. It was stucked on Google logo.
It's rooted and it has the cm7 rom.
I tryed to reflash with cw recovery but i have an issue.
I cannot copy nothing on the sdcard partition.
I mount it with recovery and correctly copy the img from my pc. After i sync and dismount but if i remount the sdcard i cannot see the file that i've copied before.
It seems strange because if i try to format sdcard from recovery it says "done" but the data still remain.
After that i tried to lock and reunlock my phone but it fail.
I launch the command fastboot oem unlock, correctly the two-choices window appear, i select yes but on my pc i see (erase fail) and bootload remain unlocked.
Please give me some advice to resurrect my phone.
Thanks for the support, and sorry for my bad english.

fastboot oem unlock wont lock it, use fastboot oem lock.
i need to unlock it. i've locked now i need to unlock.
But the procedure
fastboot oem unlock
fail with erase fail errore.
I had almost the exact same problem yesterday. Tried literally everything and nothing worked. In fact it kept getting a little worse with every battery pull/reboot.
I purposely re locked the boot loader, right before I went to Sprint and paid $38 for a working replacement.
Probably be a good long while before I root another phone.

After 4.0.4 OTA update device is bricked.
I have experienced the same issue you are discussing here.
A couple of days ago I received an OTA update to android 4.0.4 for my Nexus S device, vodafone UK. My phone is NOT rooted or OEM unlocked. The update downloaded but fails to install on reboot. The phone just returns to the original state, with the update waiting to install.
Any app or software will not work on the device, force closes error. If I attempt to restore to any factory settings or wipe / format the phone by any method you can come up with in a google search!, once the device reboots this change is ignored. If I copy any file on the Mass storage via usb, after the phone reboots the file is gone.
I've attempted to unlock the oem to flash the device in an attempt to resolve this, however when using ./fastboot oem unlock I get the following error:
... FAILED (remote: Erase Fail)
It seems the device has been screwed some how after receiving this update. It can only be a hardware error now....
Who is now responsible to fix this? i have had this Nexus S over 1 year now, can I take to Samsung or Vodafone for these guys to get repaired?
Sounds like hardware issue. Have you tried formatting the sdcard in windows or running chkdsk /F.
I Have Same Problem how can i fix it?

You can't. It's a hardware common issue without any solution. Better sent it to repair. My two cents

Just figured something out, i had the same issues as described above, could only boot the phone with a hair dryer
The new update Jelly Bean 4.1.1 is more forgiving when it comes to booting (probably voltages of the internal SD!! I'm still testing, but as far as i can see now, the phone boots normally again now (no more stuck on the google logo)
My problems:
- Not able to unlock bootloader (erase failed).
- Not possible to boot normally due to faulty internal SD card (only able to boot with the 'hairdryer' trick).
What did i do:
- Just tried the same as the trick on booting: use the hairdryer when fastbooting!!!
- Have everything ready; cmd, fastboot files, drivers etc, phone connected to computer with USB.
- Try to boot it first after heating the phone with the hairdryer (get past the google logo) and then immediately remove the battery.
- Then boot into fastboot mode (power and vol. up).
- Immediately execute the 'fastboot oem unlock' command.
Voila, that did the trick for me. Status OKAY and my bootloader was unlocked.
Then ROOT and update the phone to 4.1.1 with the following instructions:
(not able to unclude link, see webtrickz dot com/guide-to-manually-update-nexus-s-i9020ti9023-to-android-4-1-1-jelly-bean)
That did the trick for me!
NO MORE HAIRDRYER FOR ME!!
OEM unlock FAILED (remote: Erase Fail)
Hi
I'm replying to this message to share my experience about the same issu i had.
I bought a broken nexus s on google, auction described the phone as messed up during some software update. When cell got here:
- Bootloader was loading and locked
- Bootloader was reporting no boot image and no recovery
- Recovery was flashed with cwm 6.0.1.0
When trying to oem unlock, I was getting "FAILED (remote: Erase Fail)" no matter what I try. My config was good i've unlocked many nexus s with the same setup.
In recovery I was not able to mount sdcard, system, boot, nothing was working as it should.
After many frustrating hours, i saw this post.. What a stupid idea.. But I have nothing to loose at this point.
I don't have a hair dryer but I do have an oven. I figured the idea was to get the phone really hot..
Set the oven to 170, convection on and cooked the phone without the battery and cover for about 5 minutes until it was really hot but not melting.
Did the oem unlock and guess what.. It worked on first try.
After that I was able to update bootloader, radio, recovery and installed latest cm10. I've wipped the phone a couple of time, tried everything I could think of to test if something is not working, but everything does..
No hair dryer?
Just cook you phone at 170 for 5 minutes.
Worked for me.. go figure..

I'm speechless..hair dryer works for me too!!! THANK YOU GUYS!
Greetings! First of all, I would like to thank anyone who takes the time to help me diagnose and resolve this issues, let alone anyone who takes the time to read this thread.
I've been having issues with my Xoom (ICS 4.0.0) for about 3 weeks now.
A brief history of the issue's occurrence:
-I unrooted the device and returned it to stock.
-Everything was fine and dandy until one day it spontaneously said something along the lines of 'Android is upgrading..', and then performed a reset.
-Since resetting, it bootloops.
The device only turns on when plugged into a charger and hard reset.
The device only turns off when allowed to boot loop for minutes and then hard reset (it simply does not reset, and just turns off).
I'm not the most technically-savvy person with android devices but here are some things I've done/noted.
When trying to use adb commands, it does not recognize the device or properly issue commands.
I've tried wiping data/clearing cache to no avail.
EDIT: I've tried fastbooting, but the bootloader will not unlock. When trying to unlock, it simply resets and then acts as though it was never unlocked.
I have no idea how to return it to a stock image. All I know is that I have a micro-SD and some spare time.
Could anyone help me understand what exactly is going on with my Xoom?
If I can provide you with any more information, please let me know.
Thanks again. (=
If it was stock and spontaneously upgraded it sounds like a bad OTA upgrade. I've been rooted from the start so never have taken an OTA upgrade...don't you need to accept it or can it just upgrade on it's own?
Anyway, can you get it into fastboot mode?
Volume up and power, then at dual core screen, press volume down...if you see something like "entering fastboot mode" you're not bricked. You do not have to re lock your bootloader. Just make sure you have downloaded the correct stock files for your Xoom model to your PC and flash it.
If you haven't done so, just google 'recovering Xoom using fastboot' and you should get some good information.
Good luck!
Remember to grab the MZ604 files if you have the Wifi only version of the Xoom.
http://developer.motorola.com/products/software/ <------ Grab the files here. The files are for the US version of the Wifi Xoom only.
Instructions to return it to stock
1) First you need the Moto Drivers - Read this thread to START you - http://forum.xda-developers.com/showthread.php?t=981578
Should have these drivers installed if you have rooted your Xoom before.
2) Make sure you have the latest SDK - adb and fastboot should be in /platform-tools -
http://developer.android.com/sdk/index.html
Should have the android SDK if you have rooted your Xoom before.
3) Place all the downloaded stock image files into the SDK Tools folder.
4) If you are booting up from scratch, you can get the Xoom in fastboot mode by doing the following. Use command prompt to perform the rest of the steps
Hold VolDown and Power button will boot unit for fastboot mode
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
If you Xoom is booted up already follow the commands below using command prompt to perform the steps
adb reboot bootloader <---- reboots the Xoom into fastboot mode.
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
As Always If This Was Helpful Hit the Thanks!

When I try to execute fastboot commands such as 'fastboot flash boot boot.img'.. it says the following:
Device still locked. Device must be unlocked first. Failed to process command error(0x8)
Whenever I try to unlock the bootloader, it appears to be successful at first and then the device reboots. But it just reboots to a bootloop, and the bootloader still says its locked. Perhaps I made a mistake in communication. The bootloader is currently locked and will not unlock, as just described.
When I try to unlock it and it reboots, even if I access the fastboot menu right away, it still says the device is still locked.
Thoughts?
Can you get into recovery? With the Xoom off (to make sure it's really off, hold volume up + power for a few seconds), hit the power button and when you see the M logo, wait a very brief moment (like a fraction of a second) and hit the volume down button. When it says "recovery" on the top left, hit the volume up. If you can get in there, either restore a nandroid (if you have one) or do a factory reset.

Yes, I can get into android recovery. However, within a second of switching into recovery mode, the robot falls down and there appears to be a red triangle caution sign containing an exclamation point.
When trying to do a factory reset, it says all data is wiped (as normal). Upon rebooting, it continues to bootloop. So essentially the factory reset and cache clear options in the Android Recovery menu do not produce the expected results.
Pretty odd. I didn't mess with the Xoom at all prior to this issue.
Try flashing just a recovery img to hopefully get your recovery working again. I think you can flash a custom recovery even if the bootloader is locked (i could be wrong but worth a shot) I attached the Rogue "recovery-rogue-1.3.0.img". Try a "fastboot flash recovery recovery-rogue-1.3.0.img"
EDIT: Sorry, I guess you can't flash a custom recovery with a locked bootloader.

Yeah, just tried it to no avail. Thanks so much for your help anyway. (=
I'm not sure what to do now.
I would keep trying to unlock it using different USB cables and different USB ports on your computer. I've had unlocks fail a bunch of times and for some reason, it was because of a $hity USB cable and/or a bad port on my computer.

I hear ya. I've tried 2 different cords and 3 different computers. I'm using a Mac (10.6.8) right now, but have used 2 PCs (Vista + 7).
Out of curiosity, when you tried to flash the custom recovery, did you get the same "device still locked" error or did it appear to flash but then recovery failed?

I got the 'device still locked' error. Weird, huh?
How about trying to lock it again even though it says it's locked -maybe it's stuck in an "in-between state"? Try a "fastboot oem lock" and if it finishes then try a "fastboot oem unlock". I know, I'm grabbing at straws here. I thought I bricked my Xoom last week. All I did was an "adb reboot bootloader" and the device went to a black screen. Volume Up + Power did nothing. I ended up buying a T5 (Torx 5) bit at the store, removed the back cover and disconnected the battery for 30 seconds using a piece of paper to separate the contacts. The Xoom booted right up after that.

Yeah I tried that. Won't lock or unlock successfully. Locking produces no difference, and unlocking produces the same 'device still locked' error. This is getting out of hand! Thanks so much for your advice. You think I should open it up?
I hate to be so persistently annoying about this, but could anyone possibly suggest a method of working around the locked bootloader?
Is there anything I can do with an SD card to remedy the device's stubborn foolery?
I think you should give it a try, I have bricked my xoom a few times and have always been able to flash the stock imagine to recover. You really have nothing to lose by pulling the battery pin just be careful.

I don't know if I'm technically-equipped enough to do that. )=
Sounds easy, but I imagine it would be rather easy to screw something up? Essentially what I should do is unseat the battery, right?

I have a Nexus 5 that I purchased from Ebay, and I'm trying to flash stock krt16m to get the device working.
Here are some things that I've noticed:
When I fastboot oem unlock, I will see the lock state change to unlock, but then when I execute fastboot reboot-bootloader, the lock state after reboot will show locked.
This presents a problem when trying to run the script flash-all.sh because upon reboot of the boot-loader I'm unable to flash other images. So, I modified the script to do the following:
fastboot flash bootloader bootloader-hammerhead-HHZ11d.img
fastboot reboot-bootloader
fastboot oem unlock
sleep 10
fastboot flash radio radio-hammerhead-M8974A-1.0.25.0.17.img
fastboot reboot-bootloader
fastboot oem unlock
sleep 10
fastboot -w update image-hammerhead-krt16m.zip
so that I could change the lock state to unlocked after every reboot before flashing the next image.
This succeeds, but when the Nexus 5 boots, it gets stuck in an 'X' boot loop. Sometimes I see messages like Unfortunately google.process.gapps failed, or similar. I'll also get into X boot loops where I don't get error messages, but I do get messages like, "Starting apps" and similar.
I tried factory reset/wipe in recovery mode, to no avail. I get error messages like, "failed to mount cache".
I tried flashing the stock cache, then formatting it, to no avail.
I also tried to sideload the stock images with adb when in recovery mode. Also to no avail.
The Ebay listing didn't give much information, but it did mention that this was a T-Mobile Nexus 5.
Help me! What else can I do?
Sounds like a nand failure. The boot loader staying locked is a key indicator of that. There's not really much more you can do.

Just to be clear, we're talking about the part: Sandisk SDIN8DE4 16 GB NAND flash?
Is there anyway that I can prove it's bad, besides the bootloader not staying in an unlocked state?

The bootloader and the fact that you can't format anything are key signs. It's happened quite a few times on the N5 and I'm not aware of anyone who was able to fix it. Keep in mind I don't have the device in my hand but the symptoms you are describing are those of a bad nand.
I'd also vote for a corrupted NAND (As far as I remember, in the best situation the only way to fix a bad NAND is to power cycle it again.. and good luck doing that.. in the worst its just dead.). You bought a broken phone .
Also you don't need much more: If after rebooting the NAND is in the previous state, whatever you do, the NAND is broken.
Yes, your eMMC is definitely dead/damaged. It has happened to a few people, and it was the exact same every time. RMA or send in for repairs.
No one is going to "fix" the eMMC itself, not even LG, as it isn't worth the effort nor cost to do so. Any repair job will simply be a motherboard swap.
I have a HTC One MIni that is stock in a fastboot loop every time I turn it on. I can't get any option from bootloader to work. So after doing some reading here I was going to unlock the phone and try to fix it but I can't unlock the phone. So fastboot was able to get the code and I went to htdev and get the unlock.bin file and I can run it with fastboot and it says it is all good but the disclaimer that it is supposed to come up after this on the phone, never comes up. I thought maybe restarting it would show it is unlocked but no luck. So I'm stuck with the phone only booting on fastboot mode and not being able to unlock it and therefore can't install anything to fix it. Is there a way I can fix it?
Thank you
I have bought a Huawei Watch 2 on Ebay. It has arrived with a pattern lock on with no response from the seller. When trying to hard reset through fastboot loader it comes up with a large red circle with an exclamation mark in it then restarts. Anyone know how I can flash a stock sawshark onto it without being in developer mode or any other suggestions to get it working? thanks

I just ran into this same issue with mine after not wearing it for so long I forgot the PIN.
What worked for me was the following:
Install Android tools. You'll need to use `fastboot` for this to work.
Set the device in the dock and plug the USB into your computer.
Put the watch into fastboot mode the same way you have been, but don't select any options yet.
Run
Code:
fastboot oem unlock
Choose Yes on the watch when prompted. Note: Apparently this voids the warranty, but in our cases I think we're well past that anyway.
Run these commands:
Code:
fastboot erase cache
fastboot erase userdata
I still can't get into recovery, but it did factory reset the watch so I can use it again. I'm going to just lock it back up and use it as-is probably, but I assume from here you could now enable developer tools and flash whatever you want on there.
Just a quick question does unlocking the bootloader kill off GPay? Because I thought that I read something about it that said that it did. Or can you just relock the Bootloader again later. Also does does this leave a permanent mark on the device?
Got locked out of my watch after losing the phone it was connected to and not using the watch for a while. Downloaded the fastboot thing (I am inept at coding and the only cmd experience I have is running files in FDS fire simulators.) Couldnt get fastboot to work properly. Super easy way to reset the watch:
1.Keep input the wrong pattern or input to get locked out for 30s.
2. After the 30s, keep inputting wrong until it asks you if you want to reset the watch.
3. Wait for it to complete its reset!
Hope this helps someone!!!!
