[Q] Stock (unrooted, untampered) Nexus S stuck @ Google screen during bootup

Hi folks. I've tried searching on this subject and looks like every thread I've seen on this site related to a stuck Google screen was the result of trying to root the device. My situation is different. I have a stock phone given to me by Google (I'm a former Googler) and up until recently the phone started to go awry whenever I had to reboot it. It would stay stuck at the Google logo. I've tried recover, clearing the cache and also factory wipe and it will always restart and get stuck at the logo. I've found some threads on Google's support forums that mention it may be hardware related with faulty memory being the issue. I'm trying here as a last resort.
The phone is the regular Nexus S 3G for Tmobile. Please help before I smash this phone into the wall.

I'd try rooting and installing a custom rom. If it works after that and you want it to be stock again you could just reverse the process. If none of that works then I'm guessing it's similar to the other phones with hardware problems.

I can't seem to root it. I've installed the adb drivers and windows detects it whenever I plug the USB in, but I can't unlock it to root it. When I run this command, "fastboot oem unlock" it just keeps trying to detect the phone but never does. I think it's because USB debugging isn't enabled and I can't enable it without being able to get back into the phone.

you need the nexus s drivers go to the pdanet website http://junefabrics.com/android/ and download and install the free version on your desktop. then follow the on screen instructions and it will install the drivers for you. thats the easiest way to install the drivers.

I've already installed that. It won't detect the phone properly because I can't enable the USB thing within the android OS since I'm blocked from fully loading up the phone.

It sounds like the sdcard memory won't mount. This is a hardware issue.

That's interesting you say that because I do notice an error during recovery and selecting data wipe. I had a colleague in the android dept tell me it's most likely bad flash memory.
"E:format_volume: make_extf4fs failed on /dev/block/platform/s3c-sdhci.0/by-name/userdata"
I'm gonna call Samsung tomorrow.

[Q] NS4G Not recognised

Hi all,
I've got a Nexus S 4G CDMA Sprint phone running Stock ICS 4.0.4 IMM76D.
My bootloader is unlocked from previous roots and whatnot.
My problem is that my phone is not being recognized by my computer at all. We're talking complete nonrecognition. No yellow triangle in device manager, no pop-ups, nothing. This phone will just not be read by my computer! I've tried different cords, different computers, re-installation of drivers after resetting my computer, installed PDA net, did a factory reset on the phone, I've literally been on Google for hours upon hours upon hours trying to figure this out and can't figure out why the computer is not recognizing the phone and why the phone is not allowing me to put it into usb mounting. It is however, charging via the computer and wall plug. I can get into stock 3e android recovery, fastboot using V-Up and Power and I can get it into download mode. It is NOT recognized in any modes by the computer nor other computers including my Linux box. The phone states that the usb control initializes but then ends a moment later. I am thinking this is a hardware issue but that leaves me with two issues:
If I was to go to Sprint to have it fixed they would realize my bootloader was unlocked thus voiding the warranty and I'd feel like quite an idiot at the store
If it is hardware related why is the charge working on the device.
I have also tried to bend up the usb plate to make it touch the pins better but that did not help at all. I am at my wits end and really need some help here, I've done everything I could find on Google and here plus more. I want to just return it but with the bootloader unlocked this is really not a possibility. I am looking for help to either become able to lock the bootloader without it having to be connected via the computer so I can then get it fixed if it is hardware related or if I can get the darn thing to be read by the computer once more. so yea, this is where I am at and I would appreciate it so much if someone could help me out, thanks guys!!!

Wireless adb in playstore should help.
Sent from my Nexus S 4G using XDA

That would be perfect! Only problem is that it requires root access on the phone which I am unable to obtain because I cannot access the phone. Is there a way to root the phone without having to connect it via the computer? Something like an update.zip with files able to be flashed through android recovery 3e? If I can get root access than wireless adb would be perfect.
*ultimately if I could remove signature checking in Android Recovery 3e that would work so I could in turn try to root the phone and install a different recovery to then try a different rom to see if that in turn fixes the issue.

You might be able to download your rom of choice and rename it update.zip. I'm not sure if it will flash though....someone else chime in if I'm wrong. You can use wireless file transfer if needed.

Yea I've tried that, everything gets shot down by the recovery with a E:Signature Verification Failed. Thank you for your help so far but I don't think this is something that is going to be helped. I've put in a ticket to Samsung for a repair under it's warranty. In the past I've sent in a rooted phone and they've fixed it so I think I'm going to give that a shot. Just don't want to be without a phone for 2+ weeks.

Well good luck...you are running stock unrooted so it shouldn't matter. It is a dev phone for damn sake. Sorry couldn't help.
Sent from my Nexus S 4G using XDA

Well if you want to download a custom rom... Since you are on this forum. Download any rom (preferably CM9 since its quite good from my experience). Flash the stable version and wait till everything is completed. Now when you flash make sure you download a recovery...eg ClockWorkMod Recovery from google market. You should now have a custom rom installed and download wireless adb as chappy said. See if that works

[Q] Android L froze and stuck at google logo on nexus 5

I am in need of assistance as my Nexus 5 running Android L recently froze up on me at the lock screen. Not being able to unlock it, i restarted the device only to find it stuck at the Google logo. I figured i could just reflash the phone to stock android 4.4.4 via fastboot, but when connected to my pc in bootloader mode, it isnt recognized as Nexus 5, rather as Android Device. I deleted the drivers and re-installed them but no such luck, i ran out of options. I searched some threads and couldn't find a solution to my problem, so i was hoping to get some help. I'm still kind of a noob with this kind of stuff, so please excuse me if this doesn't make any sense. Is there anything else i can try?

Use proper drivers...
Or simply use a different pc

I installed the drivers using Android SDK but it still doesnt show up.
I haven't got another pc but if you think that could help, i could maybe get to one, but i was hoping i could fix it with this one.

May have bricked my Nexus 5

Hi guys hopefully I posted this in the right place. I have a rooted Nexus 5 with multirom installed and had a few ROMs in mind that I wanted to try out, most of them just installed simply and booted without problems however when I chose to try and install slimrom or another (can't remember the name of the other ROM sorry) a message would appear stating I need to install a different bootloader IMG to install/ boot that ROM. I searched around for a while and found an image to install through twrp but when I installed it I now can't boot the phone to launch a ROM or get into recovery mode as the screen will go black. Any ideas? I'm trying to used adb to install a twrp img but so far it doesn't detect the device :/ I would much appreciate any help or suggestions! Ask me if you have any questions! Thanks.

Have tried to flashing back to a completely stock rom?

Problem is I can't get my computer to recognize my nexus 5 in the boot loader mode if I could I could then flash twrp again and flash the stock rom but it doesn't detect

Does the phone boot into fastboot mode? You tried different USB ports, cables, computers, and operating systems?

The only mode I can get my Nexus into is boot loader mode so yes fast boot. I have a windows xp and 8 so I use 8 as its the only PC that I can run adb & fast boot on without problems. I have used a USB cord the recognized my sisters phone also so it shouldn't be a faulty cable I'm pretty sure. Thanks for those ideas I appreciate your help a lot!

Speaking from personal experience, I found that the USB cable could make a difference. I also have Samsung phones and, although the USB cable allowed win7 to install drivers, I could never flash anything. Once I switched back to the original cable, flashing works without any problems.

tahnks guys i managed to fix my problem using the nexus in bootloader mode on Windows 7 as windows 8 and xp wouldn't recognize it for some reason. From there i managed to install twrp reset the device, flash theserurection remix rom and flash a correct bootloader. Thanks for your help as it lead me in the right direction!

Oneplus 6 unable to be unbricked

Hi everyone,
A couple of days ago I rooted my Op6 and then decide to flash No limits rom via recovery (blu spark), as I was used to do with my last android phone, the Samsung Galaxy Note II.
Unfortunately I missed something and now it is stuck in the bootloader screen. Nothing works from the phone and I couldn’t revive it. I use a Mac but I tried all tools that are adviced here on XDA with my friend’s Sony Vaio but without success.
I managed to update drivers but I cannot run a flash-all.bat and I cannot use MSMdownload tool.
How can I do? Thanks to anyone who will manage to help me!!

EDIT: Sorry, just noticed you say you cant use the MSM tool. This one worked for me.
You could try this
https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3903272
Worked for me.

Check the guide about unbricking and if You are unable to use flash-all.bat so you Have to flash commands One by One. It's worked for me a few of months ago.

It doesn’t work either that way. I updated my drivers, but no computer is recognizing the phone.
I tried from changing usb cable or port to changing computer, to change methods.
I didn’t found any solution here on XDA, I tried everything!!

Make sure u use the cable included with the phone. Some cables doesn't work

Neither. I tried with the original and two others that I have.

if possible do you have windows? the flash-all.bat works for windows and is better to use(i was unable to use it normally in linux). What happens when you show flash.bat?

I tried Mac and Windows. On Windows it always shows in terminal "waiting for any device", even if I uploaded the drivers and made everything possible.

Did you put your OP6 into fastboot mode in correct way? I mean you might be doing the wrong procedure when entering fastboot mode.
It happened to me for the first time, I came from Samsung and I thought the phone needs to be stayed on the fastboot menu screen just like Samsung but no.
You need to turn it off and reboot it while pressing home and vol down button simultaneously until the PC recognize.
Good luck unbricking~

I always powered it on via power+volume up before connecting to the usb cable, because connecting it while powered off always resulted to power it on automatically on bootloader screen
