[Q] Is my phone brick? stuck on google boot image

I am not a noob when it comes to android dev, but this has stomped me and I am asking for expert's help. I have a GSM version SGN that I flashed the official yakju ICL53F on it via fastboot. It has been working great for a month now. Suddenly today I felt it was vibrating in my pocket, took it out and discover it was stuck in boot loop--the google sign with the unlocked icon. I waited til I get home to put clockworkmod on it, but when I try to nandroid it first it gave me an error. Then I figure I would just fastboot the stock rom on it again, using fastboot mode like I did before. I even flashed the bootloader, radio, and system image. Still stuck on google icon with screen went blank, vibrate and repeat. Is there anything else I should try? odin mode is also available, but I am not seeing any instructions on it at the developer section so I am reluctuant to try it. I can still adb and fastboot to access my phone...help please?

well I am no noob but I am no expert either. Apparently you cannot
fastboot flash system XXXXstock_image.img, you have to use
fastboot update -w XXXstock_image.img instead.
still I am baffled by why this happened in the first place. I was ready to lock the bootloader back up and send it in for warranty...glad I didn't have to resort to that.

I think you are mixing some things up.
The "update" parameter of fastboot is used to flash a group of images inside a zip file to you device.
The "flash" parameter is used to flash a single image to your device.
The following two groups of commands do the same thing:
fastboot update -w image-yakju-icl513f.zip
or
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash userdata userdata.img
fastboot flash recovery recovery.img
fastboot erase cache

[Q] Superwipe Issue

I used superwipe but then did not flash a rom. I can access the page where it says HBOOT and FASTBOOT etc but the phone is stuck on the HTC logo at the start. Also I cannot access recovery as the phone resorts to the Logo even though I flashed the latest 5.8.4.0 image successfully.
Does anybody have any idea how to get the phone fully working again?
Many thanks,
Paul

Correct me if I'm wrong but, I'm pretty sure you MUST flash a ROM after a superwipe. It erases EVERYTHING not just user data.

No I'm pretty sure your right it's just that Murphy's Law would have it that I expect somebody else has done it before so I was wondering if there was a solution in place.

I think you would have to reflash whatever ROM you were using to get it out of a bootloop.

How would I be able to do that as I can't access the recovery,

When you flashed the recovery did you run 'fastboot erase cache'?

No I don't believe so

reflash the recovery then run 'fastboot erase cache' and see if it works! When I came from the older version of CWM I had to run that so its worth a shot!

I've just reflashed the recovery but it goes to the HTC logo when I select it do you need to access the recovery to run the fastboot cache erase, the reflash also worked perfectly so it's strange I can't access it.

I would run the install.sh script to install recovery then run 'fastboot erase cache' right after it tells you successfully flashed.

Okay thanks for the help is there a tutorial for that somewhere? As I've only used cmd before.

ah. i see. i would check the CWM thread for that. I'm pretty sure it would be the same in cmd though. I use mac so I apologize if the things I'm saying are incorrect.
i would just reinstall recovery using the install-boot-windows.bat.
After that is done run fastboot-windows.exe
type the command 'fastboot erase cache'
if successful reboot and hope for the best.

Holy s*** that worked, thank you so much I was scared to put it mildly.

You're welcome! Glad to help!

[Q] Wiped Nexus, new rom didnt work, have nothing to restore to.

So I'm an idiot. I deleted everything off my Nexus 7 then I was going to flash to a new ROM, didn't work, I don't know why but it won't install. I have nothing else to install, not any other ROMs and no backups. To make the whole entire thing worse, my Nexus wont connect to my computer. Before you say to reinstall the drivers or plug it into another computer, I have, I've tried everything and nothing works. So my question is; Am I screwed or is there somehow a way to install a new ROM (seems impossible) or put the stock ROM back on? I tried the adb sideload method but I was completely unsuccessful as well as every other method I've seen/could come up with. After trying weeks to get anything back on my Nexus 7 I'm just about ready to toss this paperweight in my drawer and forget abaout it

Which modes can you get into?
TWRP allows you to mount USB OTG. Try flashing something from there.
Press Thanks If I Helped You!
Sent from my dead Nexus 7 2013 LTE! ???

Yes, like aniket0317 wrote: if all else has failed, put a ROM on a flash drive, connect it with a USB OTG adapter, and use TWRP.
I've lately had trouble getting my N7 recognized while in recovery mode, though everything's fine while in the bootloader and Android. But with TWRP it's easy to mount external flash storage and install from that.

go to fastboot mode, connect the usb cable to laptop/pc
open command prompt and go to the folder where you have extracted the 4.4.4 image
fastboot oem unlock
type flash-all.bat
if all goes well device should reboot (initally will take some time) if it took more time, reboot again into fastboot mode
this time you can try manually commands one by one
in the folder where you have extracted the 4.4.4 image you will fine "image-razor-ktu84p.zip", extract this zip file as well

and enjoy!!! do report back what happens.

fastboot -w update stockrom.zip

I'm a little confused on the instructions, also, as mentioned, my Nexus isn't recognized by my computer no matter what I try.

How does it appear in Device Manager? Have you downloaded and installed the drivers?

in the fastboot mode, after connecting your device to laptop/pc,
if you type "fastboot reboot-bootloader" in the command prompt
what happens?

I am having the exact same problem, it was installing got stuck on "erasing userdata" for over 2 hours and now nothing will work except for fastboot, and some how the device locked itself again. Only thing i can get to is fastboot mode, the computer recognizes the device. When I try to unlock it, it gets stuck in "erasing userdata" I let it run over night last night hoping it would some how work with no luck. I am unsure of what to do. Is there anyway to install a factory OS without unlocking? Every guide I've searched for has me doing an fastboot oem unlock and then the tablet freezes on erasing userdata. Any help would be greatly appreciated. Thanks!

[Q] [HELP] Bricked Galaxy Nexus (maguro)

Hello guys, a friend of mine has a galaxy nexus with some problems.
When I turn on the phone, it starts booting normally, but a few seconds after getting into "desktop" it starts popping up errors saying that the process as stopped.
I've already tried a few things, but without success. I'm running out of ideas and here I'm asking for your help.
Things I've tried:
-Boot into recovery mode and wipe all data.
The phone says that the operation completed successfully, but after rebooting the phone remains the same. All apps, wallpaper, lock screen, etc. It seems that nothing was changed by this process.
-Flash a original google ROM
Following the tutorials, the first step is to unlock the bootloader with fastboot oem unlock. The phone shows a confirmation asking if I want to unlock it, I say yes, and it shows "status: unlocked". But after rebooting the phone it is locked again!!!
I tried to flash the room without rebooting the phone after unlocking it,
Code:
fastboot flash bootloader bootloader-maguro-primela03.img
fastboot reboot-bootloader
sleep 5
fastboot flash radio radio-maguro-i9250xxla02.img
fastboot reboot-bootloader
sleep 5
fastboot -w update image-takju-imm76i.zip
The first command to flash the bootloader also says that completes successfully, but when I'm flashing the radio it will complain saying that the phone has the wrong bootloader version installed.
-Flashing via Odin
It fails when is flashing system.img to the phone
-Flash custom recovery - fastboot flash recovery recovery.img
The process completes "successfully" but when I boot into recovery mode, there is the original one and not the one I just flashed.
-emmc brickbug - partition scanner
I found this thread http://forum.xda-developers.com/showthread.php?t=1823918 and tried to run the partition scanner. As I can't have the phone on enough time to use adb shell, I tried to use this scanner via adb sideload but the phones returns an error when running it. (probably because it doesn't have busybox installed, not sure)
After trying all of steps above, the phone is still the same... nothing changed. Once, I managed to connect it to the pc as an usb storage device, and was able to copy some photos from the phone and deleted them. But after rebooting they were all there again. It seems that all write changes are not persistent.
I'm out of ideas now... Do you have any idea of what is the problem? Or any suggestion for me to try?
Thanks in advance

I believe that there is a script in the android SDK tools called flashall.bat which will reflash the kernel, bootloader, recovery, ROM ect. I'm not sure how to use it, but you could potentially try that

Hi, thanks for you suggestion, but unfortunately it didn't work.
I had a look at the flashall.bat script and it runs the same commands I run manually.
I think that the phone might have some hardware problem... Normally I would buy a new phone, but I'm trying to fix it because it is important for my friend and for me because it is challenging.
I guess that the next thing I will try, will be trying to run emmc_find_brick script by @hg42 via sideload

Try formatting /system and reinstall android. Power your device into bootloader mode. Make sure your device is unlocked. Also, make sure you have the factory image downloaded. After your device is plugged in into your computer, use this fastboot command: fastboot erase system. This will delete everything from /system. Also format /data and /cache: fastboot erase data and fastboot erase cache. After that, try installing the factory image again.

Tied everything to root swift, cant get past initial fastboot stage

hi all, sorry if this has beeen posted before but its bugging me as i spent literally 4-5 hours lastnight trying to sort it, i havee rooted 4-5 android phones in the past but im just having no luck with this one
i installed adb / fastboot minimal, enabled what needed to be enabled in developer options on the swift, booted the swift into fastboot mode, then when i run adb on my computer, the first command works 'fastboot oem unlock' but after that its constantly saying 'waiting for devices' whenever i try the next phase of commands ie. fastboot -i 0x2970 oem unlock-go etc it just wont detect the device at all in windows on adb, is there any suggestions anyone could throw out there before i end up sending it back and getting an alternative android phone thats easier to root? the only thing i can think off is its a usb driver issue? but i installed the gloogle usb drivers and it picks up the phone for file transfer etc so im not sure if this is the issue. many thanks!

Hi,
I had the same issue. When that happens, do commands without the -i 0x2970 bit. So for example:
fastboot -i 0x2970 erase recovery
becomes:
fastboot erase recovery
Hope this helps

I tried this but it still says 'waiting for any device' My initial command worked for fastboot oem unlock, but then I just couldnt do the following commands, and as a result whenever i tried to install a custom recovery / rom it gave me the error along the lines of 'unable to verify....'
edit: when i missed out the -i part, then said its already unlocked. however i still am not able to install supersu or the recovery as it still gives me the error 'signature verification failed'

Hi,
OK, what recovery are you trying to install? I would recommend TWRP 3.0.2 by Beroid (in the development section) because it's easy to use and it works. Get the image and put it in your adb folder is. Make sure you are in fastboot. Then run commands
- fastboot erase recovery
- fastboot flash recovery (name of file).img
Disconnect the device from your computer. Then remove the battery. Then replace the battery and press VOLUME DOWN and POWER to rebbot in to recovery mode to verify the installation.
You should now be in the recovery. You can flash custom roms and supersu within this new recovery.
Hope this helps
-Jev
