Navigating bootloader with no power button - Nexus S Q&A, Help & Troubleshooting

Hello,
I have a Google Nexus S, and as a lot of people out there, my power button is no longer working, and the warrany has expired. What I would like to do is install the latest version of the OS: jelly bean, but I do not want to wait for the OTA release in my country (France, with network operator Oorange).
I know that if the power button were working I could just use the .zip file with the update and install it. But the problem is that since the power button is not working, I cannot navigate in the boot menu. Does any of you know if there is a way to go around this and install the update before the OTA?
For now I do not have root access to my phone.
Thank you!

Well, you could flash the touch based CWM if you can get into fastboot and reboot into recovery from ADB. Then just flash the zip file.

Install touch based recovery such as CWM or TWRP. I don`t know it can be installed without navigating recovery.

[Q] Root + CWM without unlocking bootloader?

Hello, is there any possible way how to root Nexus S GSM ICS 4.0.4 without unlocking my bootloader.
I made it once when I wanted to update from 4.0.3 to 4.0.4 by using UnlockRoot and then instaling CWM via RomManager, but after update my recovery/CWM doesn't work, I am just getting a "dead" android with red triangle above him. It a bit wierd because I still have superuser app,but RomManager is not able to install CWM.
For as far as I know it's not possible.
I updated my NS to 4.0.4 from 4.0.3 by unlocking the Bootloader and flash CWM on it, from CWM I flashed the update to 4.0.4 and it works like a charm.
The "dead" android you see is for as I know another bug of 4.0.3, the recovery mode simply does not work.
If you are going to unlock the bootloader, please create a backup of everything, also your internal memory (photo's, videos, music etc.) Since the whole phone will be whiped.
Ok, i might be wrong but does lock on booting screen mean that my bootloader is locked? Someone told me that it says that my bootloader is unlocked...I lil'bit confused and lost
And maybe last question: Is it possible to flash CWM via Odin like other samsung devices?
Lock on the Google screen means it is unlocked. And AFAIK you can root and flash ROMs without unlocking.
ok, thanks for providing info.
Now i have to solve my not working recovery, is there any stock CWM kernel?
If you see the dead android with the red triangle above it, just hold the power button and press the vol.+ button and you'll see your recovery
Note that the padlock is actually open, hence "unlocked". Locked bootloaders show no padlock at all.
I believe there is -currently- no "official" way to root 4.0.4 without unlocking the bootloader, so i wouldn't count on it considering we have a relockable bootloader (and hence don't need exploits).
Still having prob with recovery, i flashed it via adb fastboot, but after restart is my CWM lost (really not there) again
Rename /system/etc/install-recovery.sh to something else.
problem with recovery
I also see a dead android but in my case backlight also dies out and when I press vol up + power button, phone just reboots
The official 4.0.3 has the recovery broken.
As the recovery mode cannot be used, I think unlocking bootloader then flash CWM recovery become a must.

Ok, i will try but right now i have to fix my superuser app, it's gone mad, it is not asking about permission, some apps gets it, but my root explorer not...i tried to reinstall root expl. but it didn't help, tried to delete SU data and nothing, still not getting permission for r.exp.
There is an exploit that you could use you to get root without unlocking BL or wiping phone. I used it myself and it was super easy. Unfortunately, the exploit was closed in 4.0.4(so I've heard).
If you can find a way to revert to an earlier ICS or GB check out the link below:

if your bootloader is unlocked it should say : “LOCK STATE – UNLOCKED”.
If you have a dead android and exclamation mark, it is the stock recovery. Press volume down + power button + volume up, in order. This will give you the stock recovery.
For some reason the new ICS update still has the 2.3.6 security.
use this http://nexusshacks.com/nexus-s-hacks/how-to-force-your-nexus-s-into-clockworkmod-recovery/

About this thread topic, is there any way to root without unlocking?
When I was in 2.3.6 I had my phone rooted without unlock, but lost root after the ICS update althought I still have the Superuser app in my apps even after a factory reset, so I assume it was installed as a system app.
Can I do anything to regain root now that I have Superuser already installed?

I think you can flash cwm via odin or you can try flash the cwm 5.0.1.0 via rom manager, it works for me...

First press volume down + power + volume up. This gets you into STOCK recovery.
Since ICS has a problem with the CWM recovery loading up. You can force it to go into recovery.
Heres how
type this in cmd prompt (Make sure your command prompt search is in the correct folder. Press shift and right click on your folder you have your img in. Than click run command prompt in the list): fastboot flash recovery <RECOVERY IMG>

Installing TWRP Recovery - few questions, please help

Hi,
Some could be newbie questions, please forgive. I tried my best to search and find answers.
Currently I am running on latest Stock ICS update with no Root. I am thinking of installing TWRP ported by rayman(http://forum.xda-developers.com/showthread.php?t=1759452). I read the whole thread and its been suggested as Okay to flash latest .zip using CWM to get the TWRP.
Since I am still in stick Recovery,
a) Is it still okay to simply flash the zip file using recovery? will that replace the stock recovery and get the TWRP?
b) I assume Root isn't needed for flashing TWRP, or am I wrong?
Also my Volume UP isn't working, that's main reason I am bit hesitant to play with different recovery as we does need to Power + Volume UP in some cases (though most case we use Power + Volume Down).......Can some one having much experience clarify as how important to have Volum Up working?
Thank you.
use Peri or one of the other tools to get root and recovery.....you will need root and a base recovery other than stock to really get Twrp. You may need to use a different root method if the V+ is required though.
........look on the Playstore for the "reboot recovery" app that will do the job for you without the V+ or Flash a Rom with a "reboot recovery" option in the power menu.
Once you have root id suggest getting "ota rootkeeper" from the Playstore aswell.

Recovery Bootloader

The phone will not restart in recovery mode or bootloader and then OTA updates are not installed and you can even manually, it works Droid2Bootstrapper screen and get Superuser permissions, but continues to restart in normal mode and stay with version CyanogenMod 10-20121009.
Does anybody know how to fix it, until a couple of weeks ago it was all working
If you are running CM you should NOT use Droid 2 Bootstrap recovery. Custom ROMs come with built-in recovery. Usually reachable by pressing Lock/Power and choosing Reboot → Recovery.
where did you find CM10 for D2G?
why are you trying to install ota updates?
don't use bootstrap with a custom rom

Thanks I knew of the function by power button, but just because it no longer worked I reinstalled wrong Droid2Bootstrap which I then removed. The problem is that the phone is frozen as of that version of Rom does not work and I can not see how to reinstall a new version Bootloader, sorry if broken English but I'm using google translator
Pull battery, put battery back in, press and hold up button, connect usb to pc
If it boots to bootloader, flash .sbf

If it does not, go to bootloader, phone is not fixable

Thank you all for the answers, obviously I had activated some options via Bootloader, I solved it by File Manager opening the folders System - Bootmenu - Config and changing File "default_bootmode.conf " from "2nd-init" in "1nd-init"

[Q] How to root GEDified Xoom Wifi 4.1.2

I I have been searching for the net how to root my gedified xoom wifi 4.1.2,
My main objectives are
a) Root my xoom (because it is needed for OCing, but if i can bypass this that would be better)
b) Overclock it to 1.5
I have found 1 way root my xoom but i am stuck. The instruction says open the xoom and press down to display "android recovery" after i press up to enter android recovery it show : Entering Android Recovery Mode Reading ODM fuse:1. BUT after that i get the lying android with a ! on his belly. then my xoom restarts.
Please help me overclock my xoom because when i play Chaos Rings it lags, and its really frustrating.
Up, can someone help me with this?

So the fact that you're GEDified, implies you have an unlocked bootloader.
So, Install a custom recovery, I'd recommend this one: http://forum.xda-developers.com/showthread.php?t=1235170
Then in recovery flash the zip file I have attached to root. credits to solarnz for making the zip file.
Yup i think i have a unlocked bootloader, can you give me a step by step instruction on how to install the custom recovery and flash with the zip file? (FYI: I'm a newbie in this kind of stuff)
One more thing this is my MAIN PROBLEM
I have found 1 way root my xoom but i am stuck. The instruction says open the xoom and press down to display "android recovery" after i press up to enter android recovery it show : Entering Android Recovery Mode Reading ODM fuse:1.

It's a really good, easy and simple GUI that can help install a custom recovery and more, the root function on it won't work though as I don't think it's been updated for jelly bean, but I may be wrong
yeah i think the root function wont work because i read the thread and the developer said he haven't tried it on jelly bean.Probably i'll just wait for his new update the 7heaven projekt. thanks for the help!:good:

Gedified xoom
I've been trying to access recovery on my gedified xoom and ran into the same problem. Only when i got the sleeping android with the i on the belly, the xoom did not reboot. It was just stuck like that so I pressed power button + volume up button to exit and what do you know it went into the recovery mode. The xoom now says
Android system recovery <3e>
Use volume keys to highlight ; power button to select
reboot system now
apply update from ADB
apply update from USB drive
wipe data/factory reset
wipe cache partition
Stumbled upon this by accident so dont know if it will work for you but hope it helps.

Ok so I am in the process of doing this myself. I'm kind of doing this off my own back as I cannot get the AIO tools etc to work, but there is a nice way of gaining root on 4.1.2.
So, assuming you have an unlocked bootloader and a PC on Windows do the following:
1) Download the root zip attached above in this thread.
2) Download the latest version with install scripts from here : http://forum.xda-developers.com/showthread.php?t=1782235
3) Put the root zip onto the external SD Card
4) Run the RUNME file
5) Use option 2 to boot into fastboot
6) Once fastboot is loaded use option 1
7) This will then install the recovery.
8) Power + volume up to reboot
9) Do not let the device boot into android, it will get rid of the new recovery menu, hold power (on the Motorola dual core splash) and get the device to turn off before android starts loading.
10) Once the Xoom is off, start it again, pressing the volume down key rapidly until you see some options at the top, select recovery, press volume up.
11) Welcome to your new recovery! So, we need to install the root update. So select install zip.
12) Choose the root zip, go through the options and install it.
13) Reboot your device
14) Check for SuperSU
Congratulations, you should now have root on your 4.1.2 GED'ed Xoom MZ604
Going put this in a fresh thread I think for any other self proclaimed noobs in my position

Same here... this is driving me mad... everything people describe in other posts just aint happening on my GED wifi Xoom!!
Please explain.......
1) Download the root zip attached above in this thread. -------- where?
2) Download the latest version with install scripts from here : http://forum.xda-developers.com/show....php?t=1782235 Which file??????
Here is how I rooted my xoom.
follow the directions here but instead of doing step 1 follow this for adb install http://www.support-4-you.com/main/i...ged-adb-installation&catid=40:how-tos&Itemid= it is a 1 click adb install then follow from step 2 on.
When you are done there you can install TWRP 2.4 touch screen recovery (a much better recovery than what you used to root.)
Download TWRP2.4 zip and put on the root of your external sd card. ( if you don't have a sd card we will do it another way just let me know)
Boot into recovery by turning your xoom off.
1. press power
2. when the moto dual core logo comes on wait 3 seconds and press volume down
3. recovery should be displayed across the top press volume up.
You can skip steps 1- 3 now that you are rooted if you download Quick Boot open it, select recovery and the grant Super user permission
4. go to install zip from sd card (just like when you rooted) and find the TWRP 2.4 Zip and install
5. reboot your xoom
6. you now have TWRP 2.4 recovery installed.

[Q] I think I may have unlocked my bootloader twice...

I tried to use the search and google but didn't really find anything helpful. Almost 2 years ago, I unlocked the bootloader back on honeycomb and did custom recovery, root, and custom rom. Then a little while after ICS came out, I did the OTA update.
Today, I reset the xoom back to stock ICS and tried to unlock the bootloader again...thinking nothing of it. The process was taking a few minutes so I decided to get a snack and when I came back it was rebooting.
I assumed that it worked and continued to try and fastboot a recovery image. The recovery image installed and I did another reboot but was greeted with the android welcome screen. Anyways I went through the menus and then tried to enter recovery and it gave me an android laying on its back with and exclamation point above his open chest.
I hard rebooted and can still get into my device, but adb cannot seem to find my xoom anymore. I have tried it on a 64bit desktop and laptop with no luck.
Have I messed up? Or is there a simple fix that I am missing? Thanks in advance for any help!
Can you get into fastboot mode? The second time you unlocked did you have to go through the questions on your xoom again?

Yes, I can get into fastboot by holding the volume down key and the power button. That's fastboot, right?
Yes, I had to go through the menus the second time I unlocked.
sounds like the recovery you try to fastboot did not take or the rom was corrupt.. Which recovery was it? Do you want to be rooted and run a custom rom or completely stock? what xoom do you have(wifi, 3g, 4g)

Download your rom choice, gapps and put them on the root of your sd card. If they are already there skip this step
I like TWRP Recovery the best. Easy to use and lots of options.
download this Twrp 2.4 img to the folder you hve fastboot in
open a cmd prompt in that o that folder
type fastboot flash recovery TWRPv2.4.1.0.img
Once you have verification on your device that this has been flashed, reboot your device by holding volume up + power.
Then 3 seconds after you see the Motorola logo, hit volume down. You should now see "Android Recovery" in the top left corner. Hit volume up to boot into recovery.
You should be in twrp 2.4
select backup/restore and backup your current system
select install and find your rom select asnd then swipe to flash
when done then select home
select install again and find the gapps package and install
when done select wipe dalvick/cache
when done select reboot
select system
you should be good to go.
Well I got through all of the steps, but when I try to boot I get stuck in a loop of the roms boot logo. Is it okay to flash a wingray rom over a stingray device?

I think it is fine just the 3g/4g won't work.
I can get you going again but you are going to be starting with a locked honeycomb device. You will then have to either let it update to ICS or JB or unlock, root, install custom recovery and flash a rom. What xoom do you have 3g or 4g?

Okay I restored it again but this time i did a factory reset and wipe dalvick before flashing the rom and gapps. It works! Thank you for your help!
However, could I ask how to root this thing?
since you have a custom recovery on it already and are unlocked.
Download this file Universal xoom root place it on the root of your sd card and flash it. Then reboot and try a root required app such as root checker
