Samsung Nexus S - Nexus S Q&A, Help & Troubleshooting

Hi,
My friends Samsung nexus s is stuck on the X screen. since the phone is on stock rom and no recovery installed and he doesnt want to root his phone and wants all his previous data back, what should i do to get back in orignal state without loosing data?

Well, if you unlock the booloader, then his data is gonna be lost anyways because unlocking the bootloader will factory reset the phone. The only way to get his phone working again is to unlock bootloader, and flash the firmware images, or a custom rom through recovery. Your friend is going to have to accept the change on his phone and data lost. Sorry, but I can't think of no other way to restore it WITHOUT losing data.

[Q] Is it possible to root without having to unlock bootloader?

I'm getting close to getting a new phone, and there is specific data from my Motorola Photon Q that I want to move onto my computer to put onto my new phone, but all the websites and searches for ways to root this phone say I have to unlock the bootloader, which in turn means I also have to delete all the data from my phone.
Is there a way to root my phone without having to delete all the data or unlock the bootloader?

When you rooting photon q or unlock bootloader you dont loose anything, some one wrote somewhere a bulls...
you dont lose anything from your phone, only flesh to stock or wipe / factory reset cause this not unloading bootloader or root
It is in fact, possible to root the Photon Q without unlocking your bootloader. It's called Towelroot. I did that, and it worked perfectly.

Rooting phone without data wipe

i want to know if there's a way to root your device (for the first time) without data being wiped?
i only want root access nothing more
Getting a root access doesn't wipe out data if you have an unlocked bootloader.
You cant root your phone without unlocking the bootloader.
And to unlock the bootloader there is no way you can do that without data getting lost.
So for the first time rooting phone without loosing data is not possible I guess.

Nexus 5 cant boot to system, fastboot only

Hello everyone!
I can buy a nexus5 with a low price, but it has one fault.
It boot only to fastboot mode and cant boot further, so it is possible to repair it on my own?
Heres the photo

Seller also say, that it happened after os update. It is possible, or just lie?
Thx for help
OTA updates sometimes don't work properly, especially if the system was rooted or running a custom recovery. The phone could also have a defective emmc which means the motherboard needs to be replaced.
Only way to tell for sure would be to flash a stock ROM image to the phone and test.
OK, and this phone is unlocked, yes? So, propably someone tried to repair it?
An unlocked bootloader doesn't mean the person tried to fix the phone or install modifications.
I unlock the bootloader on all of my nexus devices so I can refresh stock ROMs without losing data.

Lost Network Unlock after TWRP restore

Hi All,
I have, well now had, an unlocked Tmobile Note 5 . I was messing around with various roms without much problems until I installed the xposed framework. Long story short i could get passed the splash screen. So, i went to TWRP and installed a perfect backup I saved of Darth's rom. Upon booting i was greeted with an invalid sim message. I tried reverting to a stock backup via recovery but i had but still the same message.
Now i need to unlock again, which i can only do on a stock rom bc the tmobile unlock app recognizes I'm on a CFW.
I tried restoring the modem and EFS from a backup that was unlocked and no dice! I'm wondering which unlocking method could have possibly been used.
My question
Once I'm unlocked, which files can I save in the event I need to reinstall if lose unlocked status again?
Thanks

Relocking bootloader, stock OOS android 10

Hey, i have android 10 stable installed in my phone. Just before i updated my phone (while i still was on 9.0.9), i also unlocked my bootloader, nothing else, no twrp or root. Now i would like to relock my phone again, because google pay is not working anymore, and im not willing to root my phone, because updating problems all the time etc. so can i relock my bootloader just by using command "fastboot oem lock" on fastboot mode? or do i have to do something else before that? also, is there possibility to brick phone somehow? if so, is there a way to fix it, while using OOS with android 10? i know this is stupid question but i hope someone could anwer it. Its not first time, when something is changed due new android update, and all previous guides are wrong.. =/
only reason i unlocked my phone, was that when i had oneplus 1, it bricked somehow oneday, and only way to get it back working, was empying whole phone, but there was possibility to recover data, if bootloader is unlocked, but i didnt have that, so i lost everything.. so i unlocked this one, to prevent that problem, but now i have new, because Android Pay is not working..
I think you can use "Fastboot oem lock" as always, but it will wipe all your data (It's no way to skip that). I think it won't brick your phone
Yes, it won't brick your phone, just wipe your data.
Relocking succeed, thank you..
