[Q] Nexus S Stuck!

Hi,
today I woke up and my Nexus S was off. I turned it on and it just stucks while showing the google logo..
I tried pulling the battery, turning on.. still stucks!
so I tried do boot in Fastboot, ok.
Installed the SDK, the USB Drivers. The Nexus was recognized as "Android ADB Interface", ok.
Tried to list the device by "adb device", but I only said: list of devices attached. No device!
Then I tried "fastboot device". There it is! Trying "adb device" again, no device. mh.
So I tried to unlock the phone by typing "fastboot oem unlock".
I get the message on my phone, check "YES" and execute by pressing POWER, but no success. The phones stucks again. The cmd just says "...".
I spend 30min by watching on the cmd and the Nexus S, but no result.
What can I do?
Nexus S, locked Bootloader, 2.3.3, 2 days old

*push..*..

Can you get into the bootloader on the device? (Power and Volume Up)
Has it been rooted, and do you have CWM installed?

I can enter the the bootloader. Firmware is stock, unrooted!
I think the main problem is, that usb debug is not enabled in the device. Thats the reason why adb doesnt recognize it. But fastboot does ...

You can only use adb when the phone is booted up. Fastboot is for when the phone is in the bootloader.
Try going into recovery and doing a factory reset?

I don't know which phone you have, I'm on NS4G, got phone unlocked using GSM codes, so erased everything - a mess. When I got to backup using 2 finger method, there was nothing to reboot to
I went to Samsung site - found program called Samsung Simple DL for my phone, downloaded, executed and ran - back to stock. Kept it unlocked, but was back up and running.
I was paniced, so this might help

Problem after unlocking bootloader - Bricked?

Hey guys, how are you?
Well, I wished to root my Moto G, so I (tryed?) to unlock the bootloader. Alright, done it, but then I ran into some trouble...
After the booting up, everything started forceclosing and since then, when I try to boot it, I get a black screen after the Motorola logo.
Now, I am really really worried about my phone. I got it a month ago. I'm so afraid I really f****d up my phone right now that my hands are shaking.
I'm new to Android, so sorry if the solution is pretty obvious. And if it's not, could explain it very carefully to me? I don't know what to do.
My best wishes to you, guys.

I'm assuming you used superboot if so that would happen.
The logo sort of blured out right just press volume down and power and it would work
Or did this happen when you were just trying to unlock bootloader?

Yeah, that happenned when I was trying to unlcok bootloader.
And well, my computer now doesn't even recognizes my phone.
EDIT: It appears as "Fastboot falcon S" in the Device Manager. Tried installing some drivers I found in the Internet, but it didn't work.

Explain exactly what happened please. Was the unlock successful and did you just bootup normally after or did u do anything else in fastboot mode? Why are you trying to install fastboot drivers again, as you already wouldve had them to unlock the bootloader. Did you try installing recovery or some root img from fastboot? You said its forceclosing, but it isnt starting at all now?
Some things you can do right now (if your bootloader is unlocked) is to flash a recovery (twrp,cwm) through fastboot and if you think most system files (or settings) are beyond repair, flash your firmware version though fastboot. Will point you to the guides for them, but post more info if you want help.

Alright, just after I unlocked, when I was booting, I got a message saying that "xxxx has stopped working/failed to initialize/something like that". And then, when I rebooted, I got the usual message of the "bootlocker has been unlocked". After that, the Motorola logo started animating, but then I just got a black screen. I can't turn it off and the battery just got depleted (I'm charging right now).
When I try to connect it in my computer, the PC recognizes it as "MTP Device" or "Fastboot falcon S" when fastbooted. I can't install any drivers and the Motorola Device Manager doesn't recognizes it either.
Well, if there is some missing information, just ask me. I tried to describe my problem the best I could. Anyway, sorry for my bad English and thanks in advance for any effort trying to discover what's wrong.

Motorola Device Manager isn't helpful in this state as it doesn't handle things in fastboot. You already have all the required drivers (fastboot falcon S is the right driver afaik, falcon being motog codename) for flashing your stock firmware.
1. First, you can try the "Factory" option in bootloader (the third one, use volume down to move selector, volume up to select), though this might not really work for major issues.
2. When in fastboot mode, use "fastboot getvar all" to get the firmware details if you already didn't know about it.
3. Otherwise if yours is a standard gsm (non dualsim/non cdma), just download Blur_Version.174.44.9.falcon_umts.Retail.en.GB (UK stock for gsm, 4.4.2)
Download the mfastboot files to use rather than fastboot for flashing. You might need to modify your commands a bit for various firmwares.

All the firmwares are in either of the links below (all around 400mb):

(or)

I still don't get why many ppl are getting these errors after unlocking, very bad unlock method of moto if so ( I didnt get any such issues though).

When I use the "fastboot getvar all" command, it says "waiting for device". The phone is already connected, but the Moto G doesn't recognizes it's connected either.
I'm getting more and more afraid I really hardbricked it.

Tried installing these drivers? Your fastboot doesn't seem to be setup properly. How did you unlock without a working fastboot driver? You are trying that command in bootloader mode right?

Already installed it from the start. The message I got is always this:
"There aren't any updates for your device at the moment
Current Version: N/A"
My fastboot: Doesn't matter the operation I do, I always get this <waiting for device> and the phone is already connected into the computer. And the phone doesn't recognizes it is connected too.
And greeeeat news: my phone now doesn't charges either. I get stuck on a screen with a battery logo and 0%, when connected to the charger. Still, I still can access the fastboot mode. Well, am I lucky or not?

I'm pretty confused with this. How exactly did you unlock without a working fastboot (no waiting for device issue)? Did you change your pc drivers after unlock or trying this from a different pc? When you say "phone doesn't recognizes it is connected" you mean it says "Connect USB data cable" below "Device is UNLOCKED"? If so, maybe try another usb port cause it should normally say "Transfer Mode: USB Connected" regardless of proper drivers.
Your phone will chrarge no matter what though, no worry about that. It needs to say "Battery OK (Charging)" when connected to PC
No, as long as you have working your device isn't technically bricked in any sense. Don't worry, get that fastboot working again and anything can be fixed.
Also you didnt say whether or not you tried that "Factory" option in bootloader!

OMG. I tried that "Factory" option before but it didn't work. Now I tried a second time and it worked. Thanks a lot! Really :laugh:
Anyway, now my phone is back again and rooted. Thanks for the help, guys!

Guys the problem occurs due to corruption of /data folder. Even I had the same issue.
What you can do is
1. Connect your phone to PC in fastboot mode.
2. In fastboot, enter the command "adb erase userdata" and "adb erase cache" without quotes and reboot you phone. It will work for most of the devices, if it doesn't I have some other workaround too.

The log you have posted contains only the help commands of adb and not the actual commands you gave.
Give a try to factory reset from fastboot mode on your phone. And do you a custom recovery installed in your phone?

[Q] Nexus 5 died in the night. Fastboot works, but recovery is a black screen.

Hi all, first time posting here.
Last night my Nexus 5 turned itself off while charging. Today it won't boot past the white Google logo. I had an unlocked bootloader, but was stock with no root and no custom rom, 5.1.1. I've had the phone for over a year, and bought it from a high street UK phone chain on contract, not from the Play Store.
I've spent the last 6 hours learning, trying, reading, trying again, watching videos, trying not to punch things, but nothing works.
Here's what I know:
I can boot into fastboot mode
bootloader is unlocked
recovery mode is a permanent black screen
"adb devices" cmd in platform-tools does not find the device
I've tried tweaking Windows 7 drivers (driver for fastboot etc.) but to no avail (including using clockwork)
"fastboot devices" returns the serial code for my phone
flashing using fastboot commands gives me "flash write failure" on bootloader-hammerhead xxx .img
even "fastboot erase boot" does not work ("failed to erase partition")
"fastboot reboot-bootloader" simply turns the phone off (does not attempt even a normal reboot)
Unless I'm in some weird driver quandary, I fear my phone may be beyond help as even simple commands do not work. Any help is much appreciated.

I should mention that "flash-all" doesn't work within platform-tools.
The reboot doesn't actually work. When it says "waiting for device" I manually restart the phone into fastboot myself. And then I get write errors, when it's starts pushing the radio file.

Did you try locking the bootloader, and then unlocking it again?

Oh god , I think you have a hard bricked nexus .

Good idea! Just tried it (which it let me do) but still getting write errors running flash-all.

Given the sudden shutdown and corruption on your phone along with failure to write and to erase sounds like your internal memory has gone bad.
If that's the case you won't be able to to anything. I had the same occur with a Galaxy S3 last year and the nand memory went bad. Unfortunately it does happen, but not often. My guess is you now have a paperweight

{Q} {ASAP} Completely Bricked HTC One M4. Help!

My friend has recently given me his old phone and ask me if i could fix it for him, i took up the chance and said yeah sure, but now i am stuck and i have no clue what to do!
This phone has no operating system on it and when i got to boot it up, it goes straight to the bootloader screen with the corresponding options; "BOOTLOADER", "REBOOT", "REBOOT BOOTLOADER", "POWER DOWN".
Although i feel that it has no operating system, the bootloader says otherwise. It says that it has "OS-4.15.61.2". It is completely locked and has never been tampered with before, and using "HBOOT-2.22.000".
I have tried putting it into fastboot and then downloading the fastboot terminal, but when i type "fastboot devices" nothing shows up then when i type in something like "fastboot oem unlock" it just says "Waiting for devices". I have been searching for the last 2-3 hours and have been looking at the phone for around 4 hours. I have completely lost my sanity with this phone and it is really bugging me.
Please Help Me!
Yours Sincerely,
Mitch

Question OEM Unlock greyed out and device not found in fastboot

I'm trying to unlock bootloader, but OEM Unlock option is greyed out.
Device can enter fastboot but doesn't respond to any commands. For example "fastboot devices" do nothing. Using same computer, fastboot commands work fine with another device.
Any solutions? thanks

Try removing the sim card, or putting another carriers card in there. I seem to remember this popping up before

i've tried that and factory reset too. I guess I need to wait for few days, its only been a day.
But I'm concerned about the fastboot commands. Are those also supposed to not work until "OEM unlock" isn't grey anymore? If that's the case then good, at least it will work after few days. but if it never works then maybe bootloader can never be unlocked?

Also try installing tinyfastboot from the lineage or evo rom threads. Select the recommended moto drivers, fastboot should be fine afterwards.
