[Q] [Cry] Galaxy Nexus bricked. (Dead fastboot, dead 3e recovery, only safemode

Searched all over and google yada yada yada. So i end up opening a thread here.
Hello guys/babes/kids/oldfags/ifags in disguise . I have a galaxy nexus here that will only boot into
-download mode,
- fastboot (not working at all, pc wont detect its fastboot and buttons all dead when in recovey/fastboot)
- safe mode - will boot into safe mode if i did combo buttons when attached to charger/pc
The story :
When i booted it from batt pull via only power button press, it will go into download mode straight and if i power off or factory reset in safe mode, it will reboot back into safe mode.
I cant flash anything since fastboot is broken. Ive tried Odin back to factory image of Galaxy Nexus GSM ICS and Jellybean but the prob isnt solved and fastboot is still broken. Tried repartition and bootloader update in ODIN yet still fail. And after every successful flash of repackaged stock, it will directly boot into safe mode (for both ICS and JB factory image). Why i didnt flash using fastboot? Fastboot is broken that is. Lets continue...
Other hardwares are still fine as in safe boot, ive tested all the buttons, display, calls, speaker etc. This is fastboot relate i believe as no matter what pc ive tried and all types of gnex drivers i tried. It wont even fart when connecting to pc(win7 x86). ADB works fine though when i booted into the safe mode. Im able to do adb stuffs but whenever i query it to reboot to fastboot or recovery, a dead end again. OMAPflash the tuna edition for omap4460? Tried yet still the same.
Additional facts : The phone was not unlocked and tempered by any way before the prob happened but now the bootloader is unlocked after i flashed the repackaged ODIN (chainfire posted it)
So XDA Gnex'ers, LET THE HUNT BEGIN!

Yup, tried it but its still the same. Fastboot still dosent work and relashing packaged factory images in odin dosent fix the fastboot

Saw a Jtag service nearby and thinking of sending it in. Its roughly after conversion from RM(Malaysian Ringgit) around USD$90. Possible recovery from the issue?

does it try to create an error log? or are you able to pull bug report?
it boots into download mode and safemode so, there's hope.

First of all, bricked mean there is nothing beside a black screen. Nowaday device are hard to brick. second, One does not simply flash a gnex with odin. It's simply a big wtf that is shining through my head. 3rd, if fastboot is not working, it's because it need a special driver that i suppose you didnt install. If you can boot your phone in fastboot but can connect to it, it's because you have a broken USB port, which is not the case since you can access adb. 4th, i'm still trying to know how you achieved this. It look to me you were following some instruction and it either ended, tl;dr i will skip a few step, hope it will work which didnt or you missed electricity. Install Kies, get your phone in download and recover your phone from it. Never attempt again to play on custom rom. Man, how can someone derp a galaxy nexus, it is like the easiest device to work with.

Thx for the reply.
Some clarification here, im not the owner of this phone. Im using 9100 and im just helping a friend to recovery. Ive tried few pcs and it wont even fart when i plugged in during fastboot or recovery (i read someone that in recovery you can do some commands) but the pc(s) wont even detect a hardware being plugged in.
Plus, in fastboot, i cant press any of the hardware keys. No vol up or vol down and the power button dosent work in recovery. I only got to the 3e stock recovery via 'adb reboot recovery' during in fast mode where it booted into the relaxing chillin android with the triangle + red exclamation mark on its tummy. Pressed all buttons and it went to the 3e recovery.
At the 3e, only power button works. I cant toggle a bit using the vol keys. Note that the vol buttons work to boot the phone into fastboot and download mode and also during safe mode, all the keys works flawlessly.
So, i tried the odin method to recovery this living Gnex but with a faulty heart and kidney but it will still boot to safe mode regardless of ICS or Jellybean.
How did this happen?
I have no idea. The owner of the phone claimed that he has never rooted or tempered it in any way. Plus it was still on ICS when i first got the phone (all data was still intact but it was in safe mode at that time).
Regarding drivers, ive attempted many pcs with almost every drivers available. Shall i list em here:
- KIES
- Naked Nexus drivers
- PDA.net
- the 'official' gnex verizon driver set which is said working on GSM devices etc.
Tried those and adb+download mode works fine. Pcs detect em and tried to install the hardware n search for the drivers but not in fastboot. Its just dead.

Adb works fine so im able to pull anything when its booted. Im not sure if we can pull anything in download mode. Adb/fastboot didnt work in download mode. Am i correct? Mind to share some light here on this. And in fastboot, none. No vol keys to operate and the 4-5 pc ive tried wont even fart a sound or hint anything saying a hardware connected. Its like its a dead circuit plugged only in fastboot.
This is quite a super rare case here. Most of the dead gnex i found on the next and also in XDA has a working fastboot that only needs drivers to make it working but on this unit, even the vol keys is dead. Awkwarddddd

Great to know you are not the one who did that . So if i understand correctly, you say download mode work ? If yes, flash another stock rom from chainfire using odin. No one wan't to flash with odin, but if fastboot is not working, you shall at least try it. Also, when you are putting the phone in download mode and connecting it to kies, it should detect it has to be restored. i would say the main reason for it to not work is that android debugging is not ticked in developer options. But that would be strange that adb work on safe mode. There is probably a way to that with adb but you will have to google it. Tell your friend to follow instruction next time. And ffs, do not use odin ! (Little idea too, try to get in fastboot not connected on PC and wait a few minutes then see if you can move with the volume button, then try to connect it on pc)

Yes i have already did that few times. Few times of ICS factory image and few with JB. All are repacked version provided by chainfire. Its the full package not the software only with stripped bootloader n recovery. Its still the same

did you try flashing google's factory image in odin??
my fastboot once was unresponsive, but rebooting into it fixed it
from safemode, if you adb reboot bootloader it is unresponsive?

only suggestion left is to just boot into fastboot, leave it alone for awhile (5-10 mins), then try and plug it in and mess with it.

Try doing the whole driver thing mentioned above but instead of flashing a Google image just do the boot loader portion, what settings are you using to flash in Odin?

adb does not work in download mode/bootloader. adb only works when adbd (adb service) is started, and that happens in android boot process. it means android debug bridge.

Sorry for the long delay to anyone waiting for the answer/status.
Jtag cant fix it. Returned the device to a friend. Prolly a mobo replacement is the solution but its damn pricy here in Malaysia. It costs 80% of the price to get a new Gnex.
Hell yeah and thx to everyone supporting this.

This may be a bit late, but I have had the same issues in getting it into flash mode. There is a button inside the case (if you take the back off) then press that and hold the reset button, you'll get it into a different mode. On Windows 7 it recognises it as a disk called VDfu. From here however I have no ideas on what I can do to flash it.
I previously had a childpad that I flashed successfully with the rockchip flash tool, however with this mode on this childpad I can't get it to recognise the device in that way ...
There does appear to be some success with this, however steps don't exist for the flash procedure that I can find ...

[Q] How do I get download mode working?

I rooted my phone about a month ago using PurpleDrake and now I'm on SkyDragon G3 V0.0.5 w/ TWRP. I had never been able to boot into download but thought nothing of it since it wasn't crucial at the time. Then, yesterday I accidentally took the new OTA update, but was able to fix it with the ADB commands that others have posted. Being able to get into download mode would have made life easier so I tried to fix it today. Flashed stock boot.img and tried to re-run PurpleDrake to see if I missed a step but it won't detect my phone for a reason I don't know. At my wit's end.
Not being able to get into download mode is a concern in case I ever to fully return to stock. Wondering if any one has some insight on how I can do that or if there's some image file I need to flash, etc.?
Thanks!

Thanks for the reply. Sorry, I could have been more clear in my post. I have visited that thread and held volume up while plugging my phone in, but all that happens is the LG logo screen pops up for a few seconds, then the phone shows the charging percentage. When I try to do it from the advanced reboot menu when the phone is powered on, it simply reboots into the system. Same deal if I try to do it from TWRP. Really not sure what I'm doing wrong here. Is it possible that I somehow corrupted the bootloader or something else that's hopefully fixable?

I think you made a wrong procedure.
Take the battery out and put back in.
Press and hold volume up button.
Plug in the cable.
Release the button when you see download mode screen.
In addition, make sure you have LG PC Suite with phone driver installed.

Thanks but I have already done this with the same result as I've described. I know how it is supposed to be done with the hardware keys and I am using the stock data cable. Even watched a YouTube video demonstrating how it is to be done. Are there any other possibilities?

Just tried it with my nexus 7 cable on a different usb port (which I had done couple times before) and it worked this time! Not sure why or how but appreciate the help, everyone!

LG G2 won't boot after installing Furnace kernel

I managed to install TWRP and when I tried to flash Furnace Kernel for D803, the phone is stuck on the furnace logo doing nothing. I'd like to come back to the original kernel, but can't push file using ADB sideload cause my ADB don't detect the phone. And, download mode is doing nothing. Helpp !

This is not the right forum for this fyi. But you should still be able to get right back into recovery just fine using the button press sequence. Turn off the phone with the power button, now press the power + Volume down button till the screen turns on then once it does, immediately release them both then press them both again til a white recover screen appears. Then just tap the power button two times and it will get you back into TWRP. From here you can flash the old Rom again and it should restore the original kernel. Regardless you should be able to take it from here.

I was able to go in recovery, but not transfer file.
Anyway, i managed to transfer file into my phone, and tried to flash another kernel, and it just brick the phone. I went to the service company and they gave a me a new Phone (Galaxy S4) for free since i was still on warranty. So thanks for all your help anyway. I hated that phone, so it's good thing it bricked.

I'm sorry you had a hard time. The S4 is a decent phone yet not as good as the G2. Hope it gives you less of a head ache.

- You need OTG cable.
- Copy your ROm in flash disq
- Reboot into Recovery.
- Go to Mount.
- Choose Otg storage.
- Flash your ROM.
:good:

Flashing is not without risks but you can lessen the risks by researching and learning before flashing blindly. If things go badly, 99% of the situations can be salvaged if you don't panick and research the fix before giving up. USB OTG is cheap and provides SD Card flexibility and allows you to back up your phone or rom off-site. Newegg has Kingston microDuo 32gb USB 3.0 right now for $16. http://www.newegg.com/Product/Product.aspx?Item=N82E16820239887
You can also buy a USB OTG cable and use any flashdrive with that cable for about $1 on Epay

I cant boot my oneplus 3 at all

i installed cm14.1 today from the cyanogenmod website i had everything running fine until i reboot into recovery. i got a black screen and it didnt bot into recovery at all so i held my power button and volume down and nothing happens. i cant even boot up into fast boot or anything. nothing is turning my phone on. when i connect it to my pc nothing happens. is there anything i can do?

There's a mega unbrick guide for the OnePlus 3, use that then install the correct firmware and install the custom TWRP and re flash the ROM

i tried that method but the device doesnt even show up on my pc

Get this sorted yet? You'll need a modified TWRP recovery for the newest CM based builds. I went through the same thing yesterday or the day before. Try holding volume down and power for like 30 seconds until you feel it vibrate that it is rebooting. Then hold volume *UP* while it reboots or if you see the "your device is not safe..." flash screen hurry and press volume down and go into fastboot. From there you can fastboot flash a new recovery.

I had the same problem as well, in device manager go to ports (com & LPT) and it will show up there under qualcum device. Don't forget to go and turn off certificate verification

Thanks guys I'll try this after work. Hopefully it works. If not sure oneplus are hopefully releasing a new phone soon

No it didn't work. I have a feeling I deleted something I shouldn't have because I was clearing out my files before I restarted and that was that.

you gotta use special twrp recovery for cm14.1...

Just use the recovery rahditzz provided you with a link, if your phone is stuck on black screen with white led hold your power button until it turns off, then boot to fastboot and flash the recovery and you will boot...

Method 2 workshop 100%, unless its a hardware fault..
Are you pushing volume up while plugging in cable?

I am. To be honest its very complex too me. I'm new to android and all this is so hard. I follow steps but I'm not 100% sure what I doing. Also my computer isn't great. Do these methods work on vista? Is there a video tutorial or anything? Sorry for annoying you and you don't understand how thankful i am for your help.

I jeep getting the sahara communication failed error

Your running vista???? Good god update your OS!!

Maybe your fastboot drivers got updated? There were some reports around this. You could try reinstalling the drivers and following the unbrick guide without an internet connection.
