First time unlocking bootloader

Hey guys, I'm trying to unlock my nexus s 9020a and this is my first time doing this. I'm following this guide here
http://dottech.org/android/root-android/25412/how-to-root-nexus-s/
says it's up to date with jelly bean which is the OS i'm on. I downloaded the drivers and installed ADB and fastboot, but when I got into fastboot mode and connect my nexus s to the computer via USB, the first time i did it; it failed to install the drivers and now when i try to plug it in again, it won't do anything. windows wont even tell me that it's trying to install it again. Kinda stuck and would appreciate any help you guys might have

Try connecting your phone to your computer before booting into the fast boot menu.

Tried installing PDA Net? Mine works no matter when I plug it into my PC.

I found this thread http://forum.xda-developers.com/showthread.php?t=875580 and it mentions PDA net, but this is a really old thread for unlocking gingerbread, will it still apply for JB>?

Feiteng H7100 Bricked

Hello,
I managed to brick my new Feiteng H7100 phone, i flashed wrong rom to it and got a greenish screen when trying to start the phone.
So i formatted the phone in SPFT tool "Format whole flash" and from then it stopped responding, i cant start the phone anymore, and the charging indicator wont light up when charging.
When connecting the phone to try and reflash it the computer recognizes that i have connected the phone to the computer, but flashing doesnt work.
It is the S7180 with 1GB ram.
I hope there is a solution to it and it can be fixed, iam not sure if this can be called had brick or soft brick.
Was very close to throw it out of the window yesterday, but then thought i can give it a chance
Thanks

Have you found a solution to the problem? I have a similar problem. Dead after flash ROM
please help me
Thanks

Mine is dead also

Same mine is completely dead after I flash it - Its not recognized by the originally drivers in windows 7. Showing up as an Unknown Device.

if it is showing up as an device, it isn`t bricked. you need to get the right firmware and flash it again. force install the drivers for the unknown device or take the drivers for Rom you flashed. (e.g. flashed wrong preloader from ZTE to a Star device, need to install ZTE drivers)

While I don't know the specifics of the Feiteng H7100, I've "bricked" many an android phone and tablet. Fortunately it's usually easy to fix.
1) Reboot the device into CWM Recovery Mode (usually by holding power and volume buttons at the same time)
2) Plug it into your computer & run "adb devices" - if you device comes up as a Recovery device, then you're probably home free
3) Run an "adb push newly_downloaded_cyanogenmod_rom.zip /sdcard/" - the data location (/sdcard/ in this example) might vary depending on your device
4) Wipe Cache
5) Install Zip from sdcard and choose your new_rom.zip

[Q] LG optimus pro G bricked after using exitrecovery.zip

hello,
I hope someone can help me with my AT&T LG Optimus Pro G phone, which I have royally screwed up.
I was experimenting with the cyogen mod and after installation I installed the freegee app and once the cwm recovery was installed, I decided to go into the recovery by holding down up volume and power button.
Once I was in recovery for CWM i couldn't exit out, and the phone constantly booted into recovery after every reboot, even if i took out the battery, and powered it on.
I tried reflashing the cynogen mod through the sd card, and even though I would get success message the phone would still reboot into the cwm recovery.
I started doing research on the internet and i found file exitrecovery.zip that could be used to possibly get the phone out of the cwm recovery.
After installing exitrecovery.zip, I rebooted the phone, and now I have complete black screen. There are no light, no hints the phone is even turning on, and I can't get into recovery( or at least I can't tell). The only thing now is that when i connect the phone to the computer the window tries to install drivers for the device, and eventually prompts to insert a CD for LG drivers. I already have LGUnitedMobileDriver v.3.10.1 connection drivers installed from their website.
Please help, I am really stuck here..... and have no clue what to do. I am fairly new with rooting and modding, and I am extremely miserable.
The phone is still under warranty from LG. Anyone if all else fails, and since the phone has no screen or lights, whether they would replace it?
Attaching the exitrecovery.zip that I used.
sobbing....

hi, thanks for your reply. Again I very much new to the rooting and android OS tinkering, and nowhere close to an experienced user.
I tried to use google with your information in regards to how to use flow ROM with expansion.exe, but did not get any leads.
I would appreciate if you could elaborate more on this process.
When my phone is connect to the computer via usb is is constantly trying to install drivers. I had already installed LG usb connection drivers in the past and it was successful. It almost seems it tries to install driver yet fails after receiving no input from the phone, and then request LG CD with drivers.

Try to find driver on the web-site of producer. Set them. Overload a vehicle in Bootloader. In the controller of devices on компе must be determined your device. Then on a computer start sewing - .EXE.

Did you get this problem resolved? I have the exact problem with the exact phone!!!

thank you very much

[Q] Urgent! Stuck at bootloader but cant do anything

Hi u all!
First of all thank you for your time and sorry for my english, I speak spanish.
I have a nexus s i9023. I was using CyanogenMod 11 experimental 24042014.
I was having many problems and decided to downgrade to the stable version 10.1.2
It downloaded ok, installed all the updates, rebooted and then got stuck in the logo screen when booting.
The problem is that my nexus s has a broken the power button, it doesn't work.
As for right now the olny thing I can do is to enter the bootloader screen, but cant move throgh the options with the volume keys, it's like its stuck.
If I plug in the device when in the bootloader (fastboot mode) screen my PC doesn't recognice it, I search in the device manager but it doesn't appear.
If it helps when I plug in the battery the phone starts on in it's on.
Please, any help is appreciated.
Im really sad because I love my nexus.
Thank you!!!

Same here. Any help for us would be great. Thanks.

Seems like a driver issue. Can you try installing the drivers in a different system?
If it goes well, then use install cwm touch recovery from fastboot. You can take backup and flash new ROMs after that.
Try Nexus Root Toolkit to install drivers if you don't have access to a different system.

Don't I need to have android debugging enabled? If so, I don't think Nexus Root Toolkit will work. I flashed a ROM to my NS4g & I get boot loops. I flashed the wrong Gapps a few months ago.
I was hoping there would be a way to automatically turn android debugging on. I know it may sound dumb & also probably impossible.
Any other tips.
Tell me I'm screwed. Haha.

I disabled USB debugging. Rebooted to bootloader. Fired up 'fastboot devices' on cmd and could see my phone. This tells me that I do not need USB debugging on fastboot.
If you see an unknown device in Device Manager while in fastboot then use Universal Naked Driver to install the drivers. But since you don't, you'll need another PC to do this stuff. Once drivers are installed, you can do a 'fastboot reboot recovery' to get into recovery and fix the the problems. The first thing I advice is to flash a touch recovery. The rest is up to you.

Flash back the original soju firmware back onto your device by first using "nexus s root toolkit v.1.8.2 by wugfresh". It may take a little of your time downloading the roms and installing the drivers but trust me it should be working and your phone will boot into stock android 4.1.2. You can then root your device and install custom recovery as normal. Anything do pm me :laugh: ps, click the bricked option one the software is loaded up and remember to connect your device only and remove other phones from your computer
