tried sending as attachment . hope that works. really appreciate your help
[Samsung Galaxy Nexus] Zepius:
try this just to be sure

fastboot erase system

fastboot erase boot

fastboot erase userdata

then flash each of those before. this will make sure all 3 of those are completely clear.
[Samsung Galaxy Nexus] tejis:
tried it. still the same problem. strange because the phone was working without any issues till i was asked to update . please don't give up yet . you think it may help if i tried to use the image file for 4.0.4
[Samsung Galaxy Nexus] efrant:
What you can try is this: fast all the images, then, instead of typing "fastboot reboot" at the end, type "fastboot reboot-bootloader" to take you back to the bootloader, and then go into recovery. When you see the Android with the red triangle, hold down the power button and press volume up to get to the menu. Then do a factory reset and/or wipe cache from there. Then reboot.
[Samsung Galaxy Nexus] tejis:
tried it. still no joy. reboots a few times . gets to a screen where is says android it upgrading - optimizing apps . then back again in a loop -would it help if i tried with and older version of android or takju image and not yakju ? i may have earlier tried to flash takju 4.2

when i fastboot erase cache see a msg did you mean to fastboot format this partition ? is there an alternate command i could use?

please don't give on this yet !!!!!
[Samsung Galaxy Nexus] tejis:
managed to start in 4.0.4 . received ota for 4.1 now back in loop. aargh!! any thoughts or do i have to live with 4.0?
[Samsung Galaxy Nexus] efrant:
Did it start to bootloop with no apps installed?
[Samsung Galaxy Nexus] thephantom:
Is that a play store unit that was flashed with yakju?

Sorry for butting in efrant. Just had to ask. Don't know if you remember but I encountered a problem with a colleague's phone that had a boot loop issue with yakju which me and my friend couldn't solve. It was a takju original which accepts yakju images but never goes beyond a boot loop when taking an ota for jb. We did bring it back to takju ics and problem was solved
[Samsung Galaxy Nexus] efrant:
No, I don't remember that. Interesting though.
[Samsung Galaxy Nexus] cordell12:
anyone with stock Gnex - Verizon can help me out? Need a screeny of "about phone" I have to call verizon for my mother and she isnt close by. I know they are going to ask for this info. Her phone has SlimBean on it, of course ;)

EDIT....

if anyone needs the info in the future as of 12-14-2012 it is

Baseband version: I515.09 V. FF02/ I515.FG02

Build Number: JRO03O

Kernel Version: 3.0.31-g396c4df

Android 4.1.1
[Samsung Galaxy Nexus] tejis:
the phone was bought in Italy not from play store.cannot remember if it was takju or yakju but I do remember that it was a variant that ended in yw or some such. I had flashed stock ids after waiting ages for ota update . Worked with no problems till 4.2 became available. Then update would keep failing, on one occasion it ended up in a bootloop. Will try to install takju and get back .till now I have only managed to install yakju 4.0 .
[Samsung Galaxy Nexus] thephantom:
Interesting. Must've been a yakjuxw since it's europe based. Personally on my gnex I never really had any issues although I have a habit of flashing the original 4.0.1 yakju if I want to go back to stock. Had several otas and it was all successful. Same with if I flash takju I go with the first and do ota til the end. I know I can flash the latest directly but it's part of being OC on the rom. :D

tried takju 4.0.4 - phone still gets stuck in bootloop. even the yakju 4..4 only loads properly after numerous attempts at going into recovery and wiping cache and data
[Samsung Galaxy Nexus] thebogy:
hi guys, i'm planning to upgrade my yakju 4.1.2 to 4.2.1 using OTA.

is there any issues about 4.2.1 ? or keep i 4.1.2 until next update ? :eek:
[Samsung Galaxy Nexus] Hamletiano:
Hi all,

I just bought a lte/cdma galaxy nexus to a guy(the mobile is from EEUU, verizon version) and it does not get any signal here in Spain... would you know if i can install another gsm radio or something in order to get the signal working??

Thanks a lot in advance!.
[Samsung Galaxy Nexus] efrant:
An LTE/CDMA Galaxy Nexus does not have a GSM radio or an HSPA radio in it, so it will not work in Spain.
[Samsung Galaxy Nexus] Hamletiano:
Thanks for your answer,

Would it not be possible to change the radio to make it compatible with GSM? There is no work around?

Thanks
[Samsung Galaxy Nexus] efrant:
There is absolutely no work-around (unless you want to buy an HSPA radio chip and try to solder it on yourself... ;) ).
[Samsung Galaxy Nexus] Zepius:
yes, its called sell the LTE one, buy a GSM one.
[Samsung Galaxy Nexus] toyger:
Can i do this using a Macbook on OSX ?

Efrant - am i right in understanding that I can do this using my Macbook without having to install drivers ?

and the only command adjustment is the one i quoted above ?

or do I have to put the "./" before all commands when in my Macs terminal window (command prompt)

Thsnks
[Samsung Galaxy Nexus] efrant:
You need to put ./ before every fastboot. And yes, no drivers.
[Samsung Galaxy Nexus] dimedropper:
Noob question - My Nexus was locked with a carrier (here in the Philippines) and I was able to root and unlock it (used fuxkdocomo) so I can use another sim. Now I am selling my Nexus and I want to restore it factory stock settings (wipe all the data) without losing the "sim unlock" part. Will the steps in post #1 wipe even the sim unlock that I did?
[Samsung Galaxy Nexus] efrant:
Yes, because you didn't really unlock your phone -- you just used an app to make it appear to the SIM that it is unlocked.

You need to have a read of this.
[Samsung Galaxy Nexus] ando roido:
After starting recover of my backup I thought I made stupid move because my backup contained 4.1 system apps and I was recovering it to fresh 4.2. Later rooted and looking at system apps with Titanium I noticed that all system apps' versions were 4.4.* So I guess the recover backup is quite wise there. System does not seen to need factory reset after that either. I wish the area of recover 4.* -> 4.2 is more covered in xda.
[Samsung Galaxy Nexus] Tomaxda:
Do I need to return to stock Canadian firmware before returning my Galaxy Nexus for repair?

I purchased it several months ago from Mobilicity in Canada, and it has consistently dropped calls ever since, both on Mobi's network and on the Bell/Telus network.

I have tried a variety of different firmwares on it, but it now has one of the Google supplied yakju images on it, and the bootloader is unlocked - might Samsung use that as excuse to not fix it?
[Samsung Galaxy Nexus] efrant:
I have never heard of that happening, but I suppose it could be possible.

You could always flash a yakjuux ROM if you really want. There are two threads in the General section, and one in the Development section.
[Samsung Galaxy Nexus] toyger:
Hi , I was starting the ./fastboot-mac reboot-bootoader BUT I get a permission denied , what am i missing

i tried the ./fastbook-mac devices but i ddnt see anything what could be wrong ?

i am sure my device is unlocked , also rooted in fact

I am in fastboot mode with the big android and arrow right w START on screen when I execute the command.

Flashed the latest for VZW version, boots but won't connect, no ESN present in settings. I flashed this at work yesterday, was working on a jellybelly rom before this.

Did a FDR, full battery, on the charger. Any ideas? Should I fastboot the files again or is there a known issue that I will need to find going back a hundred pages later? Thanks all.
[Samsung Galaxy Nexus] syntrix:
Used the toolkit, and I now have an ESN/IMEI showing, must have been the corp 8 year old laptop I used the other day :) I used the toolkit on my home pc and all is good.
[Samsung Galaxy Nexus] burnetet:
Can anyone tell me if it is ok to flash the full google images through CWM or is it recommended to use fastboot?

Thanks!
[Samsung Galaxy Nexus] 3rdstring:
The images you DL from Google are fastboot, won't work in CWM
[Samsung Galaxy Nexus] PhazeDelta1:
Thank you for this.
[Samsung Galaxy Nexus] leongzhi:
Awesome guide!
[Samsung Galaxy Nexus] samersh72:
can we substitute all these commands by one command: "./flash-all.sh" ??
[Samsung Galaxy Nexus] efrant:
Yes. BUT, from post #1:

The point of this thread was to break out all the steps so that the user actually sees what he/she is doing, instead of relying on a script to do everything for him/her. This way, hopefully, if someone want to flash just a new kernel (for example), he/she has already done it, and it will be nothing new.
[Samsung Galaxy Nexus] msavic6:
I just rooted my takju 4.2.1 device and am wondering what are the steps to remove root from my device? Do I have to re-flash takju again? or is there a simpler way?
[Samsung Galaxy Nexus] chrone:
I never tried this before, but you could try to delete su from /system/xbin. Or you could try the full unroot from supersu app settings.

Sent from my Galaxy Nexus
[Samsung Galaxy Nexus] efrant:
chrone is correct.

It depends on how you got root. Root is just two file: su and Superuser.apk, and all you have to do to remove root, is remove those two files. Depending how you got root, they could be in different places.

Generally, su is located in either /system/xbin or in /system/bin, and Superuser.apk is usually located in /system/app

So, to remove root, either use a file explorer with root access or a terminal emulator on your device, or ADB, and delete those two files.

EDIT: And I think there is an option in SuperSU to remove root as well.
[Samsung Galaxy Nexus] samersh72:
and he must flash stock recovery (if custom recovery flashed) in order to receive ota update ;)
[Samsung Galaxy Nexus] Zepius:
uh, not really.

generally you can still flash the OTA with a custom recovery. it just wont auto flash the OTA.
[Samsung Galaxy Nexus] msavic6:
I used the method posted in this thread, I had to reset my phone so I just reflashed takju and am back to stock for now. Im trying to diagnose my battery issues.
[Samsung Galaxy Nexus] Brac20:
Just want to say thanks for the easy to follow guide. I'm just starting to dabble in the rooting/custom ROM world. Unlocked and rooted my One X yesterday. Today I was putting my fiancee's Nexus back to stock as the Samsung repair centre had installed a non-standard ROM when doing a basic hardware repair, this meant it wouldn't detect the update and was stuck on 4.1.1. Flashed to 4.2.1 now thanks to you guys :)
[Samsung Galaxy Nexus] Fedec:
Thank you sir, this was kindly easy to follow & understand. I was new with my Galaxy Nexus and now I learnt a lot of stuff.

Much respect. :good:

Wiping Nexus with Non-Functioning Screen

My Verizon Galaxy Nexus screen recently went completely white and now the phone is unusable. The phone is functioning, but I cannot see the screen to do anything. I need to return the phone for a warranty replacement, but I want to wipe it clean of all sensitive information before doing so. The phone was never unlocked and has been running the stock Verizon image. I would just do a hard reset, but I cannot see the screen to even complete those steps.

I found this forum and downloaded the GNex Toolkit to try to wipe the device. I followed the steps from this post to unlock the bootloader and the re-lock it. It appears to have worked to wipe the phone as I can no longer see any images in the DCIM folder when I connect it to the computer via USB.

My questions:

1. Can I assume that the entire phone was wiped back to the stock image with this process? My screen lock settings are clearly gone now and the data visible when connected via USB also indicates it worked, but is there anything else I should do to confirm?

2. If the GNex Toolkit says the process to re-lock the bootloader worked, is there any way to confirm this is true? I just want to be absolutely certain as I need to send it back for a warranty replacement and I don't want them to say the warranty is void because the bootloader is unlocked. Again, the screen is not functioning, but I would worry that they would get it working and then tell me I owe them retail price for the replacement phone.

Thanks,

Jimmy
[Samsung Galaxy Nexus] efrant:
I don't advocate using toolkits, and I generally don't answer questions related to toolkit use in this thread, but yes, unlocking the bootloader will wipe all of your data. To check if the bootloader is locked, reboot into fastboot mode and plug into your PC, open a command prompt in the same directory as your fastboot.exe file is and type: fastboot oem lock

It will tell you if it already locked. If what I said doesn't make sense to you, have a read of the first post of this thread.
[Samsung Galaxy Nexus] el_charlie:
In the bootloader it says if it's locked.

Cheers!
[Samsung Galaxy Nexus] efrant:
Pretty hard to see that if the screen doesn't work... ;)
[Samsung Galaxy Nexus] el_charlie:
Didn't read that. My bad.

Cheers!
[Samsung Galaxy Nexus] JimmySmith22:
Thanks for your help. The fastboot oem lock command said it failed because it is already locked, so I guess I am good. Hopefully, that means that everything is in good shape to ship it back for a warranty replacement. I appreciate the help and in the future I will be sure to leave USB debugging turned on at all times.
[Samsung Galaxy Nexus] skoolkaholic:
is NOT optional means, me. as noob must follow those steps ? or no ?
[Samsung Galaxy Nexus] efrant:
"Not optional for n00bs" means that if you are a n00b, then that step is not optional, it is mandatory and you must do it.

Help

Can I do this on my Gnex, my specs are: GT-I9250_EUR_XX, 4.0.1 and the build is "full_manguro-eng 4.0.1 ICL23D 285 test-keys"?
[Samsung Galaxy Nexus] Zepius:
i pointed you to this thread, so yes.
[Samsung Galaxy Nexus] GiulioPasini:
-step on how to flash the latest yakju/takju (or mysid for toro users) build available on Google's developer site. (These are full ROMs. See this thread for updating to latest OTA build using incremental updates.)

6) Make sure you have extracted ALL the files (including extracting any files in any archives inside the .tgz file). You should have six (6) files (or seven for toro and toroplus devices) ending with .img in the directory you created in step 1. The other files you extracted from the .tgz are not necessary;

I just have 5 files
[Samsung Galaxy Nexus] Zepius:
what 5 files?
[Samsung Galaxy Nexus] GiulioPasini:
The files ending with .img that I extracted using 7zip
[Samsung Galaxy Nexus] Zepius:
....

what are the names of the files?

[Samsung Galaxy Nexus] Yat_Fung:
-Re-created Windows Profile.

-Made sure no drivers relative to the GNex were installed.

-Tried in another USB port.

-Plugged in Debug mode.

-Windows automatically downloaded the Driver "Galaxy Nexus" and failed downloading "Galaxy Nexus Interface"

-Used the generic Drivers from on this forum to update the GNEX Interface driver

Verified if ADB was working with cmd: adb push su.zip /sdcard/

I maybe will do this but first I will change my system language, because it is on Portuguese (I live in Brazil) and now I am changing it to English. Let's see if it works. If it doesn't, I will do what you said.

So basically if i use this, my warranty would not be voided since its official? Thanks
[Samsung Galaxy Nexus] Zepius:
correct.
[Samsung Galaxy Nexus] samersh72:
yes, dont forget to lock the bootloader :good:
[Samsung Galaxy Nexus] adnaan146:

Thanks; Sorry for another question, but since you say i keep the official OS when i use this method, does it remove the CWM at the end of the whole process?

Use this file.
[Samsung Galaxy Nexus] arsoomro:
Cannot Load the image file

In Step 5 under the heading of D, it says:

"Flash the bootloader: fastboot flash bootloader bootloader-maguro-primela03.img (or whatever the name of the bootloader image that you downloaded)."

I have downloaded bootloader-maguro-primelc03.img but when i type this command as "fastboot flash bootloader bootloader-maguro-primelc03.img" command prompt says that it error: cannot load bootloader bootloader-maguro-primelc03.img : unknown error

And on the phone it gives fastboot status - FAILinvalid Argument.

What should I do? Whats gone wrong?
[Samsung Galaxy Nexus] efrant:
Things to check:

1) Is your bootloader unlocked?

2) Is the file actually extracted from the archive?

3) Are you typing the command in the same directory in which the bootloader file is located?

4) Are you sure you are typing the file name correctly? Maybe rename it to bootloader.img and type: fastboot flash bootloader bootloader.img
[Samsung Galaxy Nexus] Zepius:
bets on number 2 or 4 is the issue.
[Samsung Galaxy Nexus] adnaan146:
Radio

@eFrant: thanks man, its perfect now.

Now i installed Android System Info just to check if everything was as it was before, well the thing is that is says Radio: unknown and i dont remember what it was before. is this alright?

Don't worry about that. It's normal.

You can skip the bootloader and radio flash if you want. I believe they are the same. In any case, it doesn't hurt to re-flash everything...
[Samsung Galaxy Nexus] Castro27:
Yeah, it probably doesn't hurt. Thanks OP

help

When i type in fastboot boot cwm.img it says cannot load cwm.img. please help!
[Samsung Galaxy Nexus] efrant:
Do you have cwm.img in the same directory as fastboot.exe?

Is your command prompt window open in the same directory as fastboot.exe?

Are you sure you have it named cwm.img and not cwm.img.img? This is a common occurance for those that have "Show file extensions" turned off in Windows.
[Samsung Galaxy Nexus] killchain:
Quick question (again); sorry, noob here: does a factory reset/data wipe (via CWM) affect the virtual sdcard? I know it's contained under /data/media, but some sources say that it's still treated as an actual hardware device and stays intact even after a factory reset.

I'm currently running stock 4.2.1 with stock recovery and stock everything, but I wanna try AOKP 4.2.1. Can I backup my stuff (apps etc) with Titanium Backup and expect it to stay on the sdcard after the flash of the new ROM?

P.S. Sorry if this isn't the right place.
[Samsung Galaxy Nexus] efrant:
A factory reset / data wipe with the stock recovery WILL erase the virtual sdcard. It should NOT if you do the same thing using a custom recovery.
[Samsung Galaxy Nexus] killchain:
Does it make a difference if I flash CWM (or TWRP) or run either one of them via 'fastboot boot' when doing the reset, wipe and flash?
[Samsung Galaxy Nexus] Zepius:
no. they both do the same thing.
[Samsung Galaxy Nexus] killchain:
Kay, thanks to both of you. I will copy some (most) of the stuff to the HDD just in case and will report back.

Edit: Like both of you said, wiping via fastboot boot -> CWM didn't touch my sdcard, I am now running AOKP 4.2.1 and the sdcard is mounted at the same location - /storage/emulated/0 - supposedly because it's the same Android version. AOKP runs very well for now and I'll be restoring my stuff little by little from Titanium Backup. Thanks again.
[Samsung Galaxy Nexus] PhazeDelta1:
You can use either.
[Samsung Galaxy Nexus] Sathish kumar:
I followed bourne-nolonger guide to install drivers.

While updating drivers instead of "Android 1.0" my system is displaying "Galaxy Nexus". Please let me know if i can proceed.
[Samsung Galaxy Nexus] killchain:
Yes, I already got to that.

I'm not entirely sure, but I think that if you get your device listed from both 'adb devices' and 'fastboot devices', you're okay.

And if you're the same guy that posted at another forum about moving from 4.1.1 to 4.2, please let me correct you: this guide here is still valid.
[Samsung Galaxy Nexus] Sathish kumar:
In the screenshot you can see , Label 'Galaxy Nexus' displayed under both Other Devices and Portable Devices after enabling debug mode. Why is it not displaying 'Android 1.0' alone ? like the one in born-nolonger screenshot. Am totally confused :( ..
[Samsung Galaxy Nexus] samersh72:
Re: [HOW-TO] [GSM & CDMA] Return to stock for ALL Galaxy Nexus phones (latest JOP40D)

The easiest way to install driver is to install samsung kies ! To verify type in cmd prompt "adb devices" u must see a serial number for attached phone
[Samsung Galaxy Nexus] efrant:
Try right-clicking on that, then update driver, then select "let me install" or what ever it is called, then select "chose from list", then click on "have disk" and navigate to where you downloaded the driver.
[Samsung Galaxy Nexus] Sathish kumar:
I did this, please let me know if the behavior is fine.

Phone Settings -> Enable USB Debugging.

Please find the attached screen shot.

Note:

Instead of Samsung Galaxy boot loader interface am getting Samsung galaxy nexus ADB interface.

That should be ok (although that was not what I had suggested a post above yours).
[Samsung Galaxy Nexus] Sathish kumar:
Erfant first of all thanks for me helping me out in this. I did whatever you suggested in that post , you asked me to select drivers from the local machine and install , i did it. By the way when i will get "Samsung galaxy nexus boot loader interface" in device management.
[Samsung Galaxy Nexus] malcantarag:
Mac drivers?

Hi Efrant I read your tutorial several time and now I decide do it but before to start I hava some questions:

- Need I drivers for Mac OS X?

- May return to stock my GNex to 4.0.4 and later update to 4.1.2 -> 4.2.1 via OTA?

- Have any differences between Android "Normal" factory image and Android with Google Wallet besides this app?
[Samsung Galaxy Nexus] efrant:
No drivers required for MacOS.

Yes, you can flash 4.0.4, and have the OTA's update it to 4.2.1.

The difference between yakju and takju is that takju contains Wallet and Offers (I believe), and probably will get an update before yakju. That's it.
