if i knew about this last week, i would have tried it. i received a replacement n7 last week but was away from a desktop for several days. theres another method that requires an otg cable and another android device found in google groups, but i dont have a link with me. its a bit more tedious, but supposedly works.

Don't think so...I was gonna say cf-auto root with mobile odin but you need root for mobile odin

really cool , but i don't have MicroUSB - MicroUSB cable ...
how about , use something one click root applications (don't know if there is something like it exists for Gnex , but i saw such apps for older Android as 2.2 and 2.3) on stock Galaxy Nexus , and then use some terminal emulator to unlock and flash recovery ?

Back to stock recovery with broken USB port!

Hi guys!
I have a problem with my Galaxy Nexus!
The usb port does not work.
So I need to go to stock for the warranty.
I have locked again the bootloader and have a stock rom.
But I does not have a stock recovery.
How can I change it to stock?
It should be under warranty if its a hardware problem even when rooted.
Correct me if I'm wrong.

I've heard people returning their phones with it being rooted and they didn't even care. I guess if your bootloader is locked and it's on stock rom, I doubt they'll check recovery.
No I dont think so!
Normally the unlocked bootloader viod your warranty.
I fixed that part.Now I need only to fix the recovery image.
Use cloud (dropbox,drive...) to transfer the recovery.img file to ur phone then push it with terminal emulator

it seems not true with the galaxy nexus..
i read many reports from user that sent their phone (never unlocked or anything) to service, and their phone come back from service unlocked...
basically on a device like the galaxy nexus, where u can unlock and relock the bootloader, void the warranty because the bootloader is unlocked has no sense
my phone was locked but it came back unlocked from service where they replaced the mobo. A few weeks later I sent it back still unlocked and it wasn't a problem.

It does in fact 'void' your warranty though it will HIGHLY depend on where you bought your phone. Some vendors don't care whereas others will be insanely picky about being on absolute stock.

Do you still have root?.
If your USB port is broken, the VERY LAST thing you should do before sending you phone in is remove the root files.

If you have CWM, then you can flash the stock recovery. If you have a stock recovery but not the right one, there is nothing you can do.

Flash the attached file in CWM. (Warning: because your USB port does not work and you have no root, once you flash this, it is impossible to go back.)
I have the exact same issue!
Searius, could you post your steps to return to stock ROM and bootloader without using usb... looks like recovery was covered in the last post.
can you issue fastboot commands in the Terminal Emulator? I guess that would make this process easier.

No, you cannot use fastboot commands in a terminal emulator -- fastboot commands only work when your device is booted into fastboot mode. There is no terminal app in fastboot mode...
Radio: go to the radio thread and download the xxla2 CWM-flashable file and flash it.
Bootlaoder: go to the bootloader thread and download the la03 CWM-flashable file and flash it.
Kernel: I've posted one in one of my guide threads.
Recovery: mentioned above.
What remains is the ROM. If you have a nandroid backup, it would be easiest to try and use that. If not, you can try the attachment:
1) Download the yakju IMM76I factory image from here.
2) Extract the system.img file from within, add it to the root of attachment, and flash it in CWM.

I should have mentioned that I'm on VZW but I get gist of it. Thanks for the support. I'll post back if everything works out.
My phone is at the service center now,
I send it with clockwork recovery installed.
They told me today that they have ordered the part that has fault but does not mentioned nothing if the device wasn't covered by the warranty.
So I'm thinking that I'm not going to pay for the fix.
My warranty replacement comes today so I'm prepping my old one for shipment back to VZW. Is there any way to remove root from your phone? I would usually use the fastboot method but no usb...

I have no idea why it says to format drive. Probably an SD card problem?
Anyways make sure that you go to Motorola website and download latest drivers. It's called
Motorola Device Manager I think and it's available for both PC and mac.
Do i need to flash rom or what?And it says to format the phone not sd card.
My phone is mb226 does this mean i have red lenses?Cuz i dont know whick CM to install.

no, you have to install the drivers for your pc/mac, not your phone.
and that your pc recognizes your phone as mb526 only means it runs on gingerbread kernel. if you have a working camera on gb kernel, then you have a red lens device. check oit what kind of battery it has, if bf5x then you have a defy (mb525), if bf6x you have a defy+ (mb526).

Hey I recently got a glxy nexus, have some questions about rooting and flashing and some problems,
1.the first thing I don't understand is why my phone doesn't update to latest android? Still on 4.2.1, its a nexus ,so I think it should get update since first boot, anybody else have this problem?
2.so the device is not updating, I plan to root and flash it, so I'm doing this, 1. Unlock bootloader via fastboot ,,2. Flash twrp via fastboot , and start flashing roms! (These steps are my mind generated) so tell me , did I miss anything? Do I need to do something else, ? Really appreciate your answers,

hey just curious , is flashing a kernel the same way as rom? i mean do we have to flash boot.img via fastboot? and what is download mode? i heard it is used to flash stock roms on samsung devices , does it do the same on a galaxy nexus ?

kernels are normally packaged into recovery flashable zips. some include all they need inside a boot.img, some don't. if all they need is boot.img, then yes, 'fastboot flash boot boot.img' would be the correct command.
download mode is indeed the interface by which normally Samsung devices interact with a computer. It's far more easier to get an updated factory image in "fastboot format" than in Odin package files, in part because, if you're running yakju or takju, Google takes care of the software, and that's why fastboot should always have higher priority than Odin.
But yes, download mode is one more option.

don't operate the device while on low battery, put it to charge, don't let it shutdown by itself;
flash stuff for your own variant (variants: maguro, toro, toroplus) i.e. try to stick with your own variant's dev subforum, although kernels should be compatible across all variants;
give priority to fastboot, it seems you're no stranger to the tool, you have way more "freedom" with the Nexus's fastboot than with HTC's (which also uses it, I believe?);
keep platform-tools (bundled with android-sdk or in a separate package) up-to-date; current version is R17

Root without PC?

Is it possible to root the Nexus without a computer?
There was a way to install adb and fastboot an Android tablet or another phone a while back. Although I am not sure if it is still possible (the sdk updated, and I am not sure if they updated). Edit for clarification: Which if it is, you could use a tablet and an OTG cable to achieve root. Which technically would mean you don't need a PC.
Though, to actually answer your question, no you need a computer.

Solve that problem then. Try different cables, different USB ports (if on desktop try one on the back of the PC). Try uninstalling and reinstalling drivers. Try another PC.
If all of that fails, it may be a hardware issue with the phone.

[TOOL]adb_pusher(for windows)

I've made this simple and small tool seeing some people have bricked their devices BUT are able to access TWRP.
For some reasons they don't use the usb_otg, might it be they don't have the otg cable or something other, doesn't matter.
Maybe they aren't familiar with command prompt(command line), adb etc.
Q) What does this tool do ?
A) It let's you choose the desired rom, then checks if the device is connected and finally pushes the rom.zip to your internal storage.
Q) What does this tool NOT do ?
A) It doesn't install the rom.
You may add comments, questions, requests or graphic_design_help since my gui sucks badly.
Some prerequisites have to be met, adb driver should be installed. If you have ever rooted successfully that should be covered then

Hmm. Depends on which version you had installed. I think TWRP supports OTG since 2.6.3.x (not sure which version)
Hmmm maybe... I had twrp 2.6.3 and as I was worried about the device I didn't know what am I doing. I downloaded all the rooms requiring latest twrp and those didn't flash... Then I thought about adb sideload which I had totally forgotten... Then I first updated recovery via sideload then flashed paranoid Android xD
