Bricked? Trying to go back to stock....... - Nexus 5 Q&A, Help & Troubleshooting

Looks like I currently don't have a phone anymore.......and all I was trying to do was go back to stock Lollipop. I was flashing the stock images one at a time as I normally doing instead of using flashall so I could step through each one, and it looks like I accidentally flashed radio to bootloader. Scrolling back up in my command window I found my mistake and where it gave the failed: invalid bootloader message. The problem is before I noticed that I had already issued the "fastboot reboot -bootloader" command (as I was rebooting to flash radio next, and the the rom image). So now it looks like I have no vaild bootloader and I can't even boot into my TWRP recovery. All I get is the damn Google screen. Is there anything I can do to get my bootloader reflashed correctly? Looks like I can't use ADB fastboot because I can't boot to the bootloader. I think I just killed my Nexus with a freaking typo! Any help or suggestions are appreciated as I am not without a phone.

Strangest thing I ever heard. Turn off phone just press volume_down key while you connect usb cable or press volume_down + volume_up while connect usb cable.

Thanks!!!!
That worked! I think my power button may be acting flaky too. I had tried that but not with the USB cable still plugged in. Re-flashing everything now via fastboot. I haven't been on stock since Kit Kat, so I also just learned about googles fun issue where you have to extract system and boot and flash them manually since they won't fix their batch script. Thanks.

Stuck at Motorola Dual-Core? [Wifi-Only]

Hiya,
After dealing with a half-bricked Xoom, I did some research on this problem and found a solution.
If in any case, you happen to get stuck on the "Motorola Dual-Core Technology"
Solution to this (For the MZ604, One-Click rooted):
MZ604 Stock .imgs Download: http://developer.motorola.com/products/software/
*Make sure you have fastboot in the same directory as your adb for easy access*
1. Plug in your USB cord
2. Turn off your Xoom (Vol-Up + Power)
3. Boot into fastboot (Vol-Down + Power)
4. On your computer, open up a command prompt, and type the following:
Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
-or-
Code:
fastboot flash boot <path to boot.img>
fastboot flash system <path to system.img>
fastboot flash recovery <path torecovery.img>
fastboot flash userdata <path userdata.img>
fastboot erase cache
fastboot oem lock
5. Reboot the Xoom
Code:
fastboot reboot
6. There you go, back to stock!
On the real though, if you can get to Fastboot (or even the Moto "Android Recovery" state), you're not THAT bricked you've got to relock and go back to out-of-box; just keep a known-good boot.img around somewhere.
You just saved my life!
Thanks for sharing OP.
I take it this method is the same for 3.1?
I hope this works. Although, I can't turn my xoom off. It also appears that my computer will not recognize my device when it is plugged in. In addition, I can't turn off my Xoom? It just reboots... so I can't enter fastboot mode.
I just posted this in a new thread.
Lcsglvr said:
I tried reverting back to stock using the "one click" root/unroot tool that was the first to come out for the Xoom.
Anyway, I tried the unroot process and everything was going fine, until something occurred. Now, it tries to boot up and says at the Moto Dual Core Technology screen, "Failed to boot LNX 0x0004 // Starting RSD mode 2".

You can still enter fastboot if you xoom won't shut off. Just hold the appropria oncete buttons as it reboot. Happened to me last night upgrading to 3.1. It. Wouldn't shut down at all. Once I got into fastboot my computer saw it and I was able to fix
Honestly, I almost went through all of this last night when my WIFI Xoom got stuck in a boot loop.
However, I noticed that when my recovery went to flash the new 3.1 file, I felt like it didn't take as long as it should have. The file was the right size and all and it even said that everything installed successfully, but it just kept boot looping regardless of trying over and over. So I went ahead and re-downloaded the 3.1 file and repeated the steps to flash it and everything worked.
So, before you spend a whole lot of time restoring your Xoom, simply re-download the files and try it one more time. It worked for me.

hmmm... I'm in fastboot supposedly and tried to flash boot.img but it seems to be stuck at <waiting for device>
This happen to anyone else?
After search seems like a driver issue, but I have installed the drivers... I was previous rooted, so I know I have the drivers. Just to be sure, I ran the MotoHelper again. I don't understand. It's just seeing my device on the "Starting Fastboot protocol support."

Yes. How did I fix it? I returned the xoom and had a new one two days later.
If the screen says something like "Entering RSD 2" then you're boned. The xoom won't be recognized in either the current state or in fastboot state by the computer, so no amount of commands will help. Even having the stock images doesn't help with that. Even RSDLite can't see the xoom in that state.
There have been several reports of people just being honest to Motorola and them fixing the device under the warranty.
Hmm honesty. I'll give it a shot.
Sent from my ADR6300 using XDA App
Is the final OEM lock necessary? It's quite a pain as your userdata gets wiped if you unlock it...
I was stuck on bootloop, with unrecognised device, through adb was able to get back into clockwork recovery somehow at first boot, think twice down volume? Could be wrong.
I was able tto rreflash zip 3.1 over thet top again.
sry if this is different and unhelpful, bu imagine things are pretty desperate if you are considering returning the device

You're not boned at all. I had that happen to me so I just got back into fastboot, downloaded the files in the OP put ADB, Fastboot and the adb extensions into the file I downloaded then ran the commands and got me XOOM back up and running fine.

You were likely in RSD 3, which is recognized by the computer. RSD 2 means adb and fastboot cannot see the device at all, so no flashing images is possible.
There's several states that all look very similar. Because some success was had with one doesn't mean it works for all. Motorola recognizes and is telling users that, in this state, the device needs to be sent back to them.
Can someone help us wifi xoom. Im stuck on the motorola screen and have a lil experience. I can fast boot reboot/fastboot device and it work but cant get the files from the hwi69 to fastboot on to it. I think im entering the commands wrong. Any advice would be appreciated

Very good info to get into fastboot protocol:
Much thanks for the info. Worked like a champ. On an updated 3.2.1 XOOM I did an unlock, re-locked the wrong way, soft bricked, unbricked back to locked state. Finally followed your steps applied stock files and XOOM is re-locked and stock rocking back at 3.01. I needed to do all this to make sure I could get it back to stock in case it goes back to BB in 2 weeks. I was lucky enough to find one at a BB just not sure if I'll keep it. I plan on trying out some roms plus I heard Motorola is planning on doing an ICS push to the XOOM. ICS is very nice. It runs great on my unlocked Verizon G-Nex.. Again Thanks..
This post not only saved my half-bricked non-rooted Xoom, but also let me flash it from the Singapore firmware (bought if from Amazon, don't ask lol) to the regular USA firmware so that I can properly root it!
Thank you so very much!!

Boot Loop

A few days ago I tried getting my phone to s-off using the "[how to] manually achieve s-off,simunlock,supercid for Inspire 4g/DHD" guide on the Android forums. (Sorry, I can't post direct links.)
I got to the part where I was supposed to type in "fastboot flash boot boot.img" to the command line but I accidentally skipped that part and typed in "fastboot boot recovery recovery.img". I stopped everything and tried to start over but when I turned my phone back on I was stuck in a boot loop. Going to hboot and trying to choose Recovery or Factory Reset only results in more boot looping.
I've tried putting PD98IMG.zip on the SD card and booting it, but it only reads it and says "Parsing..." before doing nothing. Attempting to enter recovery mode after this makes it enter the boot loop again.
I've also tried using the HTC Sense and RUU from AT&T on my computer to fix the issue. My phone can connect to my PC after choosing fastboot from the hboot menu. The RUU can see the device and it starts recovering it, as my phone shows a black background with HTC on it. But the RUU stops after trying to update the signature saying "The ROM Update Utility cannot update your Android phone. Please get the correct ROM Update Utility and try again." I am 99% positive I am using the correct RUU.
I've searched high and low on the internet for a similar situation, but everyone else seems to have their problems solved using either of these steps. Thanks for any help.
Without knowing what you did (since you haven't given us a step-by-step and can't post links), we don't know how to help.
Sorry about that. I'll try to explain what I did the best I can.
Before using the guide, I managed to root my phone and used it for a few days, so everything was fine then. I later decided to s-off it so I could flash a custom ROM to it. Using the guide I mentioned above, I created a mini-adb directory in my C: drive with the ace-tools.zip that I downloaded. Using the command line I copied my stock boot image, though to where I do not know. (I feel like a fool for doing all this without being sure of what I was doing exactly. I deserve what came to me.) Then, using the command line I made my SD card a gold card. After that I changed the "misc version" (?) to allow installation of the downgrade firmware, and then relocked the boot loader and booted back into fastboot. Then I flashed the downgrade software and unlocked it again. It's here that my phone was supposed to be unable to boot, and I was supposed to flash the boot image but skipped that step.
Now I'm unsure of what I have to do, and I only want to get my device working again.
I wish I could post the link to the exact topic, but since I can't I guess you'd have to search the topic name to see exactly what the directions were trying to get me to do.
Thanks again.
Can you boot the phone into fastboot and flash the boot.img from fastboot?
No, with the PD98IMG.zip file it simply says "Parsing..." and stops there. With any other boot image it doesn't acknowledge it at all. Even though the computer makes the sound that it's connected to the device when it's in fastboot, adb can't recognize that's it's there in the command line.

Wait. What? Not PD98IMG.zip from hboot. Extract the boot.img and flash from fastboot, not adb.
Ah, thanks for the clarification. I'm supposed to extract the boot.img to the SD card and enter fastboot on my phone, correct? Because I've just done so and nothing happened. I have the options Bootloader, Reboot, Reboot Bootloader, and Power Down, and the Bootloader option only takes me back to the hboot screen.
Sorry if I've misunderstood you.

No, the boot.img needs to be on your computer. Your phone needs to be in fastboot mode. From the folder where the boot.img is saved,
Code:
fastboot flash boot boot.img
I can't use the command prompt to connect with the device because it can't see it. I always get an "error: device not found" instead.
Is your phone in fastboot mode?
Yes. It's odd: the RUU software identifies it and knows it's there, but can't actually fix the issue. The command prompt just doesn't notice it at all.

So you're booting into hboot, navigating to fastboot with the volume buttons, and selecting it with the power button? What does fastboot devices say?
I'm assuming by "fastboot devices" you mean what it says in the command prompt.
...Well what do you know, it recognized it. I was typing in "adb devices" instead of "fastboot devices". So it can recognize it after all.
I'm assuming I have to load the boot.img now?
Hey hey, wa-hey!
That was much easier than I thought it would be! A simple "fastboot flash boot boot.img" followed by a fastboot flash recovery recovery.img" using some image files I made before messing everything up did the trick. Thank god I did so.
Everything's back to normal; my phone escaped the boot loop. And last but not least, I don't have to buy a new phone.
Thanks so much for helping me out, even if it was clearing a few things up for me. I appreciate it.

You're welcome. You could also have fastboot flashed any custom recovery image, flashed a ROM from recovery, and fastboot flashed that ROM's boot.img. So you weren't too badly off.

[Q] Need help after rooting (phone won't reboot)

Hi,
My Moto G XT1032 was on 5.0.2 when I finally decided to root it. I followed the instructions here (reddit.com/r/MotoG/comments/22mimr/the_guide_to_rooting_the_motog_with_a_howto) and all was going well until right at the end after I installed the supersu zip and rebooted.
Right now, every time I try booting up my phone, it shows the Moto G logo (without the bootloader warning since I flashed the original logo), the Motorola animation, and then my screen goes black. I don't however think it's off, since when I plug my phone into my computer, it's eventually detected (but nothing is there when I open the internal storage; likewise, 'adb devices' reveals nothing attached).
When I use volume down + power, I can reach the fastboot screen, but selecting recovery only brings me to a screen with the text 'no command'. The only strange thing I can recall during the entire root process is that when I was in CWM and making my backup image, the screen was flickering slightly.
Does anyone know what I can try at this point?
Thanks for your time and any help you can provide,

With the phone off, hold the power and volume down buttons simultaneously for 5 seconds to access the bootloader. From there you can you fastboot commands to restore stock. Find your stock firmware here http://www.filefactory.com/folder/c6cdedc45a775d27
Follow the steps in the guide I posted originally.
Edit: You could also reflash recovery via fastboot. fastboot flash recovery recovery.img
Also the line on your screen is do to Lollipop bootloader. The recovery you are using is probably for KitKat bootloader. There may not be a Lollipop bootloader compatible recovery available for you device yet.

Bootloader Flash from TWRP (anything flash?)?

I was trying to install a ROM and things got a bit messed up. I wiped system/cache/dalvik/data via TWRP. I then went to install the ROM but it failed due to only supporting hhz12h bootloader.
So now I'm kind of stuck. I can't update the bootloader because fastboot/ADB won't list the device in TWRP. Is there any way to launch an ADB server in TWRP so I can fastboot the bootloader? Doesn't look like there is.
If there's not:
Is there a TWRP zip-install hhz12h bootloader I can use? Looked around, couldn't find one.
If not I'll have to try and find/flash the original image..but fastboot is not going to happen so I have to find a zip installable one that'll work with hhz12d bootloader...which hopefully is around. Otherwise I could install literally anything just to get an ADB server so I can fastboot the hhz12h bootloader in there. Stupid problem to have right here, lol.
Any thoughts/help is appreciated. TIA.
Okay, so I got around the issue. I'm not sure if TWRP is supposed to be able to fastboot or ADB but mine would not, I was under the impression that I could fastboot or ADB in recovery. Maybe that was just a mistake on my part thinking that.
My workaround:
- Reboot into the bootloader (not TWRP recovery), 3 finger reset, power off, then power button + vol up + vol down until you get the OEM Android bootloader screen (unplug if plugged in, it didn't seem to want to go into bootloader when it was plugged in - maybe I just didn't wait long enough, but unplug if it doesn't want to go into the bootloader).
- From here I was able to fastboot, "fastboot devices" listed it
- I then flashed the bootloader: "fastboot flash bootloader bootloader-hammerhead-hhz12h.img" (may differ if you wan to flash different bootloader)
- I then rebooted into bootloader: "fastboot reboot-bootloader"
- I then flashed recovery: "fastboot flash recovery openrecovery-twrp-2.8.5.2-hammerhead.img" (may differ for different version of recovery)
- I then used vol up/vol down to select "reboot recovery", and hit the power button
- TWRP booted and from there, now that I have the hhz12h.img bootloader flashed I could install the ROM, so I wiped data/dalvik/cache/system again, installed the ROM, installed Gapps, and rebooted, good to go.
FYI ADB works into recovery mode (TWRP) and Android. Fastboot can only be used when you are in the bootloader.
You did the right thing except that it wasn't necessary to flash TWRP. Flashing a bootloader.img only erases the boot partition so the recovery isn't concerned.

Got it. For whatever reason I could not get ADB to see the device while I was in TWRP. I tried the ADB sideload feature in 'advanced' but it just waited and waited and waited forever. I believe ADB is set up properly on my system because it works fine on ROM. Not sure what the deal is with that, but I don't have much reason to go into ADB in recovery anyway aside from this issue, so it's [hopefully] not a big deal.
As for flashing the recovery, yeah, bad habit I guess. On my old phone (Fascinate Galaxy S 1), if you had custom recovery and had to 3-finger reset to bootloader because your phone wouldn't turn on or was bootlooping or whatever the recovery was boned, had to re-odin flash it. So it's stuck in my memory now that if I had to 3 finger it I better flash recovery. I'll try to knock myself out of that habit .
Thanks!

Haha, I didn't even look at the dates, I just went to the "Tools/Utilities" page for the Nexus 5 and it was the top link....I didn't think too much on it, just figured top link = most recent = latest.
http://forum.xda-developers.com/showthread.php?t=2511507
I'll dig around for a thread which has latest and flash that on there, can't expect old versions to work flawlessly, now can we?
EDIT:
That actually might have just been a copy/paste error on my part, as I had the old TWRP lying around for fastboot and copy/pasted the name from that. I used TWRP (ROOT) app to install and I chose latest (or so I thought). Now I have literally NO idea which one I was using -_-.
No worries glad you got it sorted. You can flash an image file in twrp now BTW.

LG GPAD 7 stuck on Fast Boot

Purchased an Lg Gpad 7 Wifi tablet (v400) 2 weeks ago. Came with preinstalled Lollipop android so i couldnt install a recovery rom to flash any other custom roms. Downgraded to Kitkat version following the instructions on Xda forums and succesfully installed Twrp. When i installed Cyanogenmod 12.1 through Twrp i got stuck in fastboot screen.
Any suggestions and / or solutions would be greatly appreciated.
I had a similar problem.. Only mine was stuck at the bootloader. Go in TWRP and repair /data and other partitions. My data partition gave me an error since F2FS is a little flaky and some ROMs corrupted it (claimed they supported it). I would recommend erasing the system, cache and data partition if you can't get into TWRP.
The problem is i cant get out of fastboot whatever i try. It says start on bootloader but the tablet just restarts on an empty screen doing nothing.

if you have an sd card, try removing that, then reboot.
if that doesnt work, try entering fastboot command, fastboot continue
Tried without sdcard and i get the same fastboot screen.

you said it was stuck on fastboot, if thats the case, install any needed drivers on your pc, connect device to it, open a terminal in the fastboot dir (after you go get fastboot), then try those commands i gave. you could also try, fastboot reboot dont think i mentioned that before.

Did as you said but every command i gave gives me an error message in adb terminal. There are new lines in fastboot menu in tablet now. Bottom two are SECURE BOOT - enabled & LOCK STATE - locked.

hmm, ok, im guessing it would have said that normally, when not broken. all the command does is try to release it past where its stuck. it doesnt actually flash, lock, unlock, or change anything.
imo, this seems good, because now we know fastboot is working.
i own lg devices, but not your specific device. i would hate to give you some bad advice and make your tablet broken more, but if it were me in this situation, i would try to flash the factory KK firmware you used to downgrade with odin or however you did it. hopefully, that will clean everything up and let it boot properly.
if for whatever reason you cant do that, we could try extracting the factory file, and just flashing recovery and system, those should be the only things that got changed putting on twrp and cm normally.
Sorry, I have the serious proplem wtih my LG pad V400, I rooted it and using <LG Flash Tool 2014> with <V40010c_00.kdz> to downgrate the firmware but their is error then my LG pad stuck in fastboot menu as with just turn off, restart and restart bootloader. if i seclect one one them the tablet just logged again the fastboot menu
it stuck on the fastboot menu and i cannot do nay think with it. I can restart with factory restore mode but when select yes to restore, it will restart and log in fastboot menu again.
I downloaded adb and fastboot program and put in one folder <Minimal ADB and Fastboot> in C:\Program Files (x86)\Minimal ADB and Fastboot
I dont have recovery image so i download file <cm-13.0-20160421-NIGHTLY-v400-recovery.img> form your link to download TWRP file
move it to folder of fastboot programe and changed its name to <recovery.img>
I turn on the tablet and it waited at fastboot menu
when i run the command <fasboot flash recovery recovery.img> and they said some thing wrong like in picture
please help me
