N00b in need of help. Lock Bootloader?! - Nexus S Q&A, Help & Troubleshooting

Hi,
I've posted a thread or two on here but I cant get any proper help or instructions to help me out
Basically, my phone has its boot loader unlocked (lock symbol shows up) and I have tried all methods to lock it but nothing works.
I cant boot the phone into recovery, and drivers arent very coperative either
I need help! ... I'm planning on selling my phone ,so need to restore it asap.
The problem started when I first bought the phone, it wouldnt update or reboot, so I tried a one click root, it unlocked the bootloader and everything looked fine. UNTIL, an OTA update came along, I applied it, but when my phone came to restart it was stuck on the google logo. I cant even update anymore
Pleease could someone help this n00b out? Really appreciated
Thanks!

Read. No seriously, these forums are chockful of help threads and guides on how to root your phone, install a custom recovery, fix your phone when it's stuck.
Since you want to go back to stock, I'll give you a hint...
1) Unlock bootloader using fastboot (DONE!)
2) Flash custom recovery using fastboot
3) Wipe data/factory reset in custom recovery
4) Install Gingerbread 2.3.6 in custom recovery
5) Lock bootloader using fastboot
Edit: If you're having trouble getting your phone to be recognized in fastboot mode, use the PDANet drivers for Windows. Usually that does it.

Thanks for the reply.
Trust me, I've read around this forum a lot! I've tried the drivers with PDA net but still nothing works. The drivers (adb I think) aren't recognised so can't get anywhere.
I get easily lost with the guides. I don't think they're newbie friendly. I .e. where am I supposed to type 'fastboot oem lock'?
Btw I have no custom rom installed ( I don't think) and when I downloaded the root checker from the market, my phone is recognised as not being rooted (even though I can't apply updates :/ )
I think main thing is that my phone isn't recognised in fastboot mode....

Thanks a lot for your help! I owe u polobunny , I can now lock the bootloader BUT, Ive rooted my device with 'twrp' and want to flash a ICS ROM. Which ROM would you reccomend and to install it do I add the rom to SD card and install from twrp interface? Or is it more complicated than that ?
Thankss

Installing the Rom should be the same regardless of recovery. Yes put the rom on the SD card and flash away.

Thanks but do I need to wipe data/restore or can I just flash?

Oh boy, you do need to read my friend.
In recovery (twerp, twink, Clockwork, whatever) back up your current set up. Then... I suggest you wipe data/factory reset, then wipe dalvik and cache yes. I do it 3 times on Clockwork just to be sure. The cleaner you get it the less problems you will incur. I always wipe fresh unless instructed specifically to do otherwise.
Flash your Rom, gapps, kernel and enjoy.

[Q] Bricked Nexus S, have clockwork recovery running

Hi guys I've been looking around and I'm a total noob at all this, but I went ahead and tried to root my Nexus S anyway.
Here's the site I used,
http://forum.xda-developers.com/showthread.php?t=878446
I don't really know what happened, but I have the little unlocked logo under google, but that google screen is all I can get. I can start it in fastboot mode, and when I click recovery it brings me to clockwork recovery page. I kinda just tried a bunch of weird things but everytime I try anything it keeps getting stuck at the google screen over and over again.
I'm really clueless.. If anyone could help me please give me your advice!
If it helps, I have clockwork version 3.0.0.0
you have to perform a nandroid restore or flash a ROM.
might as well update your recovery too.. wouldn't hurt
http://forum.xda-developers.com/showthread.php?t=988686
rename img to recovery.img
boot into bootloader
fastboot flash recovery recovery.img
go into recovery
when you finish downloading the rom/nandriod, go into mounts and storage and mount usb and put your sdcard
I'm sorry what is rom flashing or nandroid restore?
The clockwork update is confusing too.. I'd like to avoid that if possible..
Sorry looked up both of them and it looks like I actually need my phone to be working in order to do it?
I've read and it says it doesn't really help on stocked android phones?
The nadroid restore is the -backup and restore option in clockwork yes?

It doesnt really help if you reboot the phone cause with stock rom, every reboot flashes back the stock recovery.
what you should do is follow the steps @Zephik described above ( but without rebooting the phone) and you'll be able to enter the clockwork recovery ( a modified recovery allowing you to do a backup or rom flashing...) '
rom flashing is installing a rom modified by users for a better and faster user experience.

[Q] Screen stuck when try to reboot

Hi,
Im trying to root my HTC ONE S. I followed all the steps that suggested in the forums, but when I reboot the phone in the final step, it got stuck in the 'HTC quietly brilliant' screen. I left it there for 20 min or so, it didn't change. I am able to go to the recovery mode but I don't know what to do. I did a factory reset attempting to go back to the original software but it didn't work either. Any ideas what can I do? Im in real trouble if Im not able to use my phone anymore.
Thanks in advance,

Well if you are installing a custom ROM then there is no need to root before hand, you just need a custom recovery installed. The custom ROM will have root access enabled.
If you are asking how to just be rooted on a stock rom, then I would just google how to do it like you would. But I assume you install custom recovery, download a supersu.zip and install via recovery.

Hi, thank you for the reply
Well, I have no access to the sd card, it says it's not mounted. I can't copy any files to the phone, therefore I can't reinstall it from the phone. Sorry for my ignorance, but I don't know what to do next.

seems to be a common that the sdcard can become corrupted.
If that is the case, having the stock recovery on and then booting the phone into bootloader and selecting "clear storage" fixes the issue.
Then you need to flash custom recovery again, and mount usb storage.
For the S4 Ville version of this phone and not the S3 VilleC2

Hi,
I tried to do what you told me, but now I can´t even go into the recovery mode. I can only access the bootloader; anytime I select recovery mode it shows this (image below), after a few minutes it reboots and stays with the white screen ´HTE quietly brilliant´. I can´t copy any files either because the computer doesn´t read the sd card. Any ideas?
Thank you for your time.

That is good, that is the stock recovery, basically saying you don't have access to it.
But you don't need to go into recovery, it is there just to fix the issue when you enter the bootloader and pick "clear storage"
So get back to the bootloader and clear storage. Then you will need to flash the recovery of your choice, CWM or TWRP. You should now be able to access usb storage. (unless you are using the special TWRP in the Maximus thread meant for hboot 2.16, then it just doesn't work)

Yes, it worked. Thank you.
But, which ROM should I install now? I tried with the SU, but the screen was stuck again. Do I need the phone in S-off mode? how do I do that? I saw that many ROM's need this.
Thank you again for your help, very appreciated

You are welcome.
You only need S-Off if the rom says 2.16 HBoot required.
So there are a lot of different ones to try. As long as your Hboot is 2.15, if not then you need to upgrade your firmware to that. You see your HBoot in the bootloader screen.
So ya, most of the roms are ok with S-on, you just have to remember to:
fastboot flash boot boot.img
So on your pc download the rom, unzip it you will see the boot.img move that to fastboot folder and fastboot flash it.
Then you can move the ROM.zip to your phone and install via recovery.
Don't forget to wipe caches before rebooting. (when installing, if that particular rom opens up Aroma installer and one of the options is to wipe, do that but don't wipe again when back to recovery)
The sense based roms are generally more stable and like stock.
The CyanogenMod may have a few little bugs.
Just browse around and see which one you like.
It all worked out pretty well.
I'm trying with the MagioRom, seems to be very stable!
Thank you for your help, you literally saved my HTC!
:good:

[Q] Stuck during cyanogenmod install

Dear XDA community,
I installed Clockwork recovery and the USB drivers. The device is unlocked and when in fastboot mode it is correctly identified by my PC as falcon XT1302 with an USB connection. When in recovery mode, the device appears as "Android" in the devices menu in Windows 7 and there is a yellow "!" next to it. Unfortunately after formatting system and deleting the cache as per instructions the device won't boot up. I'm stuck at the bootloader unlock warning screen. I can access fastboot mode and recovery mode but that's it.
I want to place the cyanogenmod zip inside the internal SD card of the Moto G but adb doesn't work. I get the device not found error when inputting a command. adb devices returns a blank. I don't know which drivers to install or what to do. I've tried various fixes on forums but none work. Maybe USB debugging is the problem although I distinctly remember switching it on. In any case, I can't boot so I can't change the settings.
All I want is a way to place the cyano .zip in the phone /sdcard so that I can install it. I'm all out of ideas. USB mounting doesn't seem to work. Neither does sideloader (or maybe I messed it up?) I am at wit's end.
I didn't have anything important on my phone so I did not make a backup. In hindsight, this was a stupid mistake. I've certainly learned a lot during the install attempt.
If possible please give step by step instructions. I am not a very technical person. Any help would be greatly appreciated. pls halp
kind regards
Dont worry too much if you can acces Fast Boot just download STOCK Firmware for your version I can't post links cuz im beginer searc under help "Restore STOCK Firmware" and flash it. :fingers-crossed:
Reply here i will tell you how if you not fixed it alredy
Thanks but that's not really what I want to do. I want to flash cyanogenmod on it.

Thanks to the users who replied. I've managed to solve the problem. :laugh:
Would have been faster though to get your device recognized while in recovery. You can install the driver manually and it should work. Just search for seperate driver files and ignore the Windows message that it is probably 'not compatible etc.'.
Then your device is connected properly and you can get ADB sideload to work from your recovery.

Can't get my new tf700t to root or install recovery.

Hey guys.
I just got a very nice condition used TF700T. I am trying to get recovery to install so I can flash a rom. I used the Transformer Toolkit to unlock it, which worked, it says device unlocked when booting.
But I absolutely cannot get it to Root, or flash recovery. If I try using debugfs root generic 2.3 it fails to write everything. If I try to flash any recovery with the toolkit it downloads and says flashing but just sits at about 25%, it boots my device into the screen that says usb fastboot mode with the three icons that say RCK Android and factory wipe. If I click the RCK it says rebooting and then goes to android mascot installing icon, but then the one with an X and error appears. What on earth am I doing wrong?
Is it the latest 4.2 update locking me out? Can I downgrade? I just can't get anything to root or flash recovery no matter what I do. I feel a little defeated being a long time member and 3 phone habitual rom flasher :crying:\
Any ideas what i'm missing?

What custom recovery are you installing? You may want to try with fastboot or adb method to flash your custom recovery which doesn't require rooted device, good luck....

Well I tried TWRP 2.7.1.1 I believe and also CWM , and Phil's custom touch CWM that all three are options to flash with the all in one ADB Toolkit app via USB from windows (http://forum.xda-developers.com/showthread.php?t=2094746)
How do I do the Fastboot method? I read about that, but have no idea how the process goes. I'm ok with skipping root and going straight to recovery and a rom because I can just flash superuser after if the rom isn't rooted already.

I wanted to try an app I used to get twrp onto my LG G2 for the first time called "flashify" that worked like a charm. I just installed the app, downloaded the twrp file and flashed it then it reboots to recovery, but it requires root as far as I know. Does unlocking the boot loader allow things like this?

Unlocked bootloader is allowed you to install the custom recovery so you can install the custom ROM, I believed..... You can check this guide out to see if you can setup your fastboot/adb. It is very easy to follow for the beginners, good luck....:fingers-crossed:

Once you unlocked the bootloader you can flash a custom recovery and after that - the sky's the limit.
Flashify works great, and it is a wonderful tool as long as you're able to boot into Android.
My problem with Flashify and Goomanager and TwrpManger is that it saves users from setting up a proper ADB/fastboot connection from PC to tablet.
As long as you can boot Android, these apps are great. But what if you can't? Once the tablet doesn't boot it's so much harder (and often too late) to get the correct drivers installed for ADB and fastboot.
So if you flash your recovery with any of those apps still make sure you have access with ADB and fastboot from your PC.
You will regret it if you don't - I (almost) guarantee it.
That's an excellent point. Thanks. I did actually get the Fastboot method to work. The problem was that I kept clicking into RCK recovery when I ws supposed to just leave it on that screen to push twrp instead. I got recover and just got done doing a backup. I'm about the flash my first rom (http://forum.xda-developers.com/showthread.php?t=2672751). Do we need to do factory reset / wipe data/system etc? The instructions on the ROM post say to just flash it from twrp so I'm guessing it has a built in wipe feature during install?

The instructions in the OP actually say that you have to do a full wipe (Factory Wipe) in TWRP coming from a different rom base. Which would be you unless you had a version of CROMBi-KK installed prior to this.
It's the default selection under the Wipe menu in TWRP. Just do that and then flash the rom and your ok.
Do not use the Factory Reset option from Settings or the Wipe Data option from the BL menu! Do this in TWRP only!
Cool thanks. I figured so because that's the norm with roms on all my phones. Thanks a lot for the help guys. So happy to be get KK running on my new toy!
Just wanted to update. KK 4.4.3 rom flashed and booted in. It's much nicer. The stock was a little laggy, and KK breathed a lot of new life into my ancient single core 1.0 ghz Galaxy S that I use as a music player so I figured it would help make the tab real nice and snappy too. Gotta go now, much fun to be had!!

[Completed] HTC One X Trying to install ROM but stuck with problems.

Hi, so recently my HTC One X has been acting up so I decided to install a ROM to make it much faster, so I had to unlock the bootloader. When i've done that I flashed CWM on my device. Then I tried to install a rom that was on the device and it didn't install which leads me to my first problem, the page said I needed to reset everything and use the fastboot command to flash the zip file that worked but when I went to CWM (to install gapps) the device never booted in the ROM just kept going back to CWM. So I googled this and there was multiple things I tired out like adb command etc also it would be easier if this problem was fixed if this button worked (mount USB storage) I press that and it does not work. So then I don't know what to do. I'm stuck here please help me the rom was cm-11-20160815-NIGHTLY-endeavoru.zip.
