[Q] Nexus S 4G won't boot past Google Screen!!

I tried rooting my phone, but when I flashed CWM my Nexus S stopped booting... it freezes on the Google screen in the intro. I can boot into Fastboot, and cwm, but I cant connect the Internal memory to the computer without it booting like it is supposed to. Does anybody know of anything I can do to fix my phone and bring it back to stock??

There are guides for returning to stock stickied in the Nexus S 4G Android Development forum.
Before you do that though, try flashing a different recovery, like the one linked to here or here.
Btw, which guide did you use? You're not the first person to have this problem, and it's really bugging me (though probably not as much as it's bugging you :-o).

I will try a different recovery, but how would I flash a rom if I can connect my phone via usb mount?

I'm a little out of my depth here, but I think it's
fastboot flash system system.img.
You don't need to put the rom image on the sdcard. Just put it in the same folder as fastboot.

It was titled "How to Root Nexus S!"
And I will try to flash recovery and try that rom command, thank you )

There's a button for that.

I got the link. Thanks. I looks like you flashed a boot image that is incompatible with your phone. That guide was for the T-Mobile Nexus S. (Why they're screwing with the boot.img to begin with, I really don't understand.)
Download the attached file, and unzip it to the same folder as fastboot. The md5 sum is d4a9508f9321eb25df3383f00f571e8b. Then
Code:
fastboot flash boot boot.img
You'll probably also want to use one of the recoveries listed above to
Code:
fastboot flash recovery recovery.img
, but leave system alone for now. Flash that only as a last resort.

OMG!! im having the same issue. could you please post the link for ODIN so i can return to stock and take it from there please? I rely on my phone so much and i need it asap thank you.

same problem with me.
but in my case, the phone not only freeze after the google logo before boot. I tried several times to pull the battery and start the phone again, it took several times until the phone can boot normally again.
After that, my nexus s can work as usual. but it only takes 3-4 hour until it freeze/hangs or reboot automatically and show image of green robot lay down with red alert triangle...
sometimes I noticed all application force closed like gmail, gtalk, etc. (its a basic apps instead of 3rd party app)
History :
- root GB 2.37 using superoneclick
- upgrade OTA to ICS 4.04
- problem happens
- root using guide : nexusshacks.com
- unroot using guide : nexusshacks.com
- back to factory setting on GB 2.34
- upgrade OTA to ICS 4.04
- Still got that problem.....
I'm using Nexus S 4G Sprint, pls help me guys...

nexus s won't boot
I had the same problem and read elsewhere that heating the phone with a hairdryer solves the problem.
I must say, indeed it did.
I removed the battery and the SIM card, then heated up the phone (so it really feels warm) put back the battery and sim and simsalebim the phone started again. and is still working since (now already a few day's)
It seems that a component in the phone is heat sensitive, the question in my mind is when will this show again and do I need to consider buying a new phone.
But sofar it works
PS I also tried hard reset factory reset the lot, but in the end only heating up helped.
Good luck, David

I fixed this problem! but I had to wipe all user data by rooting it using nexusrootICS. It finally boots up and the phone works now... that's all I need.

"starting services" does not stop...on boot up

Hi all , just joined xda-developers but i spend straight 14 hours trying to fix this DAMM photon q yesterday
all i got in the end is a normal boot after following this http://forum.xda-developers.com/showthread.php?t=2001108
BUT at the startup , the screen comes like for a millisecond and then this " starting services" logo doesn't go at all...it just continues forever
any help would be appreciate .

Can you explain what your setup is, and exactly what you've done to get where you are?
For example, you were bootloader official unlocked, on CWM and asa-10, etc.
Thanks.

Still doesn't tell me what you've done, what state the phone is actually in, etc.
I thought my question was pretty straightforward. Unless you provide more detail, I don't know how anyone will be able to help you.
Is this a stolen device? Why is it not qualified for the official unlock? Either way, how does that play into what's wrong with the device?
Did you have custom recovery on it? Give some details!!!

i think i am a noob at explaining things but let me try again...i don't know the exact history of this phone , my friend gave it to me yesterday and its not stolen ... he paid his insurance every month but then who know what he did... i have no idea why its not qaulified for the official unlock probably because he bought a new phone on the same line so the company deactivated this phone..
ok so when i got the phone yesterday , the bootlocker logo appeared and i was unable to do anything ...then i installed CWMrecovery and it was successfull and then i installed every possible rom available online as far as i know but same thing happened with all of them ..... successfully installed , it reboots and little square thing saying " starting services..." and then it does not go away at all ... but at the same time i am able to bring the top menu ..and go to the settings and everything from there but i can't go to home screen since ...it is black and is occupied by "starting services.."
so finally i came accross this thread for master reboot and i followed it ....i installed TWRrecovery and made backup and then restored a backup providers by that guy ... i flashed new stock recovery after that... so following his thread , he told that if all went successful ... it will return to original stock
and now i am at the same screen as previous... " starting serivces..." my friend told me he tired to root it and he messed up really bad ..so i believe there is still some old files in the internal storage from previous rom versions.... but i deleted everything......wiped, data facotry reset and then
installed a clean backup provided by the thread starter...... and everyone else had success except me ...
i hope i answered your questions if not .. i would aprreciate if you tell me what exactly you want to know ..... thanks

i also tired every US ROMS from here http://sbf.droid-developers.org/asanti_c/list.php
and all of them showed " starting services.." after i installed them from sdcard using CWMrecovery.

You have to extract the files and edit the xml file. And you use rsdlite on your pc phone connected thru usb to write it to the phone

Reactivate in Sprint? What do you mean? Only Sprint can tell you whether the phone can be activated or not. Call them. Not sure why you would even worry about that if it's not stolen.....

Ok I think I will go in store and see what happens...

moto g does not boot

hello everyone,
i'm developing a game with unity and sometimes when i compile and inject the game on the phone it crashes and forces me to factory reset the phone through fastboot. i've done it like 3 times already with no problems.
but today it happened again and the phone just wouldnt recover, i've tried the fix that this video (youtube.com/watch?v=laU6NQ0LxR0) shows but it still does not boot.
I am able to enter fastboot and my computer recognizes the mobile phone so that's a great start :victory:
not sure what guide to follow since i'm not sure whether the problem is on the rom or something else.
can someone give me a tip on what fix should I try? cant really afford to lose my phone right now
it has (had) a stock rom 4.4.2 with stock bootloader, tho i tried to install the fix in the video i've said earlier and i'm not sure whether it changed the rom or not.
thanks

/Data gets corrupted
Even, I had the same issue. I tried flashing ROMs through recovery but it gave me error that/data/media/0/ can't be mounted. The only way to get out I found was to full format /data and /storage (philz recovery) and then to push ROM. zip to/sdcard through adb and then to flash it through recovery.
Hope it helps someone.:angel:

[Q] HELP! Verizon Galaxy S 5 Bricked / Stuck In Boot Loop

Problem resolved thanks to bweN diorD!

Dark System said:
Hey everyone, I figured this was the right section to post a question, sorry if I was mistaken.
So I recently rooted my phone and tried to install a custom ROM on it, turns out the ROM I selected was probably for the wrong model or something because my screen was just black. So I booted into recovery to try and restore it on the ROM I backed up and it was gone so now I'm kinda ****ed on a phone for now, before I look into buying a new one I wanna see if there's any way I can resolve this and unbrick it.
When I turn the phone on it just loops the booting screen and when I boot into recovery it just has the droid dude with an exclamation mark on it then turns off and does the boot loop.
I was wondering if maybe there's a file I can put on an external drive and it will automatically restore back to stock like on other devices.
I've done a lot stuff like this to my PS3 just never tried it for my phone so I'm just hoping there's a method out there for me, please provide any feedback or questions about it, I'm just trying to get this resolved and I have no time really to research it because of work and a newborn baby plus you guys would know more about it than me so yeah. Thanks!

usually when you flash the wrong software to a phone it is toast, but you may be in luck as it still turns on.

further instruction here.
if that doesnt work... well its not good unfortunately.

Alright thank you! I'm pretty confident this will work, once the stock ROM file finishes downloading, which it doesn't seem that it wants to work. I've downloaded it 5 times now and every time it's done it's a fail.. I'll keep trying though.

[Q] Nexus 5 Stuck in four circles after installing app

Hi Amazing people
I have somehow managed to kill my phone. I tried updating one of my apps and the performance went downhill. I then tried to restart the device and it got stuck on the four spinning circles. I can access recovery mode but I don't want to wipe the device as it has files I still want.
Can I boot the nexus into Safe Mode from powered off state?
or what do you recommend without me losing my files???
Help ME please

Have you a custom ROM ? And what is your ROM version ? What are the four circles you are describing ?
You can try going to recovery (stock one if not bootloader unlocked), and erasing cache files android.gs/how-to-boot -reassemble URL I can't post URL without 10 posts- -recovery-mode-for-google-nexus-5/
If it doesn't work you can try to flash all stock fastboot images but it erase all data because you have to unlock it and it erase even the (simulated) SD card (where your photos are).
It is very complicated because you don't have an unlocked bootloader. Can you even boot in the system ? Getting to the lockscreen ? Or you have a bootloop?
Explain more please
