Help - device not booting - RAZR HD Q&A, Help & Troubleshooting

I was already on stock 4.4.2. Used RSD to flash it when the phone was on JB. My phone's suddenly not botting anymore though. Just stock on the boot animation screen. I tried flashing back the same firmware, but I get "Phone Returned Failed" error on RSD lite every time
What can I do? My phone was completely stock. Bootloader wasn't unlocked.
*edit*: Boot animation runs fine. Then it's just stuck at the orb thingy which just keeps going.

Need more details on "fail." Just saying it failed won't narrow down anything.

you have to edit the xml file and completely remove the line containing "gpt" in that error. the partition table cant be changed/downgraded once upgraded.

still luck. Whatever item it tries to flash it returns the same error. I even deleted everything in between that to system.img. Gives the same error trying to flash system.img

Mmk, do not use rsd, use the bat file at the bottom of the directory. You defeated the purpose of it by using rsd.

Ran the script twice. Managed to copy this the second time :/. Phone reboots after flashing is done and like before still stuck at the end of the boot animation.

hmm, not good!
it looks like the hole phone is r/o when in fastboot. i have seen this before several times and have yet to see any one fix it.
i thought a few of those may fail, although you weren't actually downgrading any of them, they shouldn't have, but every writing and erasing command has failed. i was hoping that didn't happen.
we didn't try a factory reset but that's pointless, as the script tried it and it failed.
i dont think there is a way to fix this. maybe @SamuriHL has an idea.
just so you know Sam, the "modified" script i gave him a few post down uses moto fastboot to flash everything.
figured that was the best shot, if there was one, given what he already tried.
thanks

Without having read everything cause I'm pressed for time, my gut instinct says this:
USB cable (make sure it's the oem cable that came with the phone...yes, it matters), USB port (usb 2.0 NOT 3.0), or USB driver issue.

thanks!
i hope its something that simple. since the other instances were unlocked devices running custom recovery (with other mitigating factors), this seems rarely fixable as none of the other causes for a true r/o situation apply here.
im afraid to tell him to try a fdr in recovery, as i have seen quite a few cases go worse lately for no reason.
maybe a simple fix is what is needed.
thanks for your input either way.

I always try simple before moving on to the hard stuff. To me it feels like a communication issue with the phone but I don't know for sure. It's a guess. I'd start there at the very least.

Well a factory reset was the first thing I tried anyway. So no luck there. I've tried it with the OEM cable on my laptop as well as a different cable on my PC. Not sure about the USB 3.0 or 2.0 though. I have a lenovo x230 laptop with 2 USB 3.0 ports so ill try again and see if using those ports with the OEM cable makes a difference.

You can not use a USB 3 port. It will fail.

Nope. Tried it on my PC and laptop both on the usb 2.0 port with the oem cable. Still the same

I would go an uninstall all drivers, reboot, and then reinstall the drivers and then hook your phone up again to see if that helps. Could be either drivers are corrupted or something else is hosed up.
Since you've tried it on two different computers and it failed, I'm assuming you used the same drivers on both machines? What version of the drivers are you using?
You might want to go to the moto site and get the Motorola helper to bring down the drivers.

i assume you've tried both RSD Lite and motofastboot?

results from mfastboot are in post 9.
failed writing and or erasing at every step. i made the script for him, he posted the results.
even if a couple would have failed as writing equal code, they all wouldn't have as it flashes each separately.

Yea, not a situation I've seen before. Almost like the partition table is screwed up somehow so it doesn't know the mount points to flash to. Just for fun, let's try something.
Boot her up in AP Fastboot mode, connect it to USB 2.0, then try this:
o) From a cmd prompt, type: fastboot oem fb_mode_clear
o) Then flash the FXZ again either with motofastboot or RSD.
I'm just curious.

[Q] XT925 with XT926 Firmware Brick

I need some help right here. I have flashed XT925 by mistake with stock veryzon 4.1.2 (XT926 firmware). I'm stuck in fastboot mode, my Bootloader is LOCKED, thats really weird because I was unlocked before I've tried to update via OTA (my phone was bricked after that OTA update fail). I tried to flash Retail Brasil JB and some other firmwares via fastboot and RSD Lite 6.1.5 with no results... this is what my fastboot screen shows up:
---------------------o---------------------------------
Device is LOCKED, Status Code: 0
Battery OK
Connect USB
Data Cable
downgraded security version
update gpt_main version failed
failed to hab check for gpt_backup: 0x35
failed to load GPT
CID Read failure
Invalid CID status 0x69
No SP partition found
Fastboot Reason: Invalid GPT
----------------------o---------------------------------
Hope you can help me :S
Are you sure you were unlocked? Seems to me you may be screwed.

Yes I'm sure, my status code was 3 not 0. What do you think I can do now? Is there any solution?
I remember seeing something about the gpt while searching for a solution for a different fastboot error. But like you I'm to lazy to search for it. Since it is your problem you probably should.

I tried the newest Retail Br, Telcel Mexico and one from Veryzon for XT926 with no results.
I can't flash anything in fastboot or in RSD Lite, so maybe I will take it to Telcel, they will send it to Motorola and let's see what they say. Hope they don't notice that I unlocked the bootloader, although it says that is LOCKED and status = 0... let's see what happens
Any other ideas? Please, there must be something to do to fix this.

Make sure your phone is recognized in fastboot mode. While in fastboot mode type the following in the command prompt:
Code:
fastboot devices
You should see the devices serial number in the output.
If that works type the following in the command prompt while in fastboot mode:
Code:
fastboot oem fb_mode_clear
Then type the following:
Code:
fastboot reboot-bootloader
When it reboots back into the bootloader attempt to flash the stock firmware again.

If this is truly what you get when you try to flash then I can guarentee your phone is not connected correctly. It should say USB Connected where it currently says Connect USB.

Make sure the correct drivers are installed. You can get them from HERE. Note that windows will remove your drivers at will. So even if you had them installed before, install them again.

It doesn't work. I've just tried that and I just can't flash a single Rom. The "fastboot oem fb_mode_clear" command doesn't work, I can't clear my fastboot screen on my device.
Sorry but my phone its connected properly, it says usb connected at the end of the screen. I reinstalled drivers too, but nothing changes, so maybe I'm screwed.

Power it off and charge it with a wall charger. I believe you cannot fastboot if the charge is below 50%.
Where does it fail? What does the utility say?

What are the errors you get when flashing the stock firmware for your carrier?

[Q] Droid Razr HD XT926 won't boot, different flash errors.

I was given a droid razr hd (xt926). Guy said he took an update and when the phone rebooted, it wouldn't go past the M boot screen. I don't know what build he was on and I don't know the previous status of the phone (root, rom, unlock, etc)
I can access AP Fastboot but I can't access anything else (Recovery, BP Tools, Factory).
I am using a Team Black Hat Cable, the most recent Motorola_End_User_Driver_Installation_6.4.0_32bit Driver, and a Windows 7 computer (my best computer is at ASUS getting fixed).
AP Fastboot Reads:
Code:
AP Fastboot Flash Mode (S)

I first tried RSD Lite (using both 6.1.4 and 6.2.4 to flash VZW_XT926_4.4.2-KDA20.62-15.1_1FF.xml
I got:
Code:
Failed flashing process. 1/17 flash partition "gpt.bin" -> phone return FAIL
Trying VZW_XT926_4.4.2-KDA20.62-10.1_CFC_1FF.xml I had to delete the "getvar" line for it to begin BUT I also get the "gpt.bin" failed message here. If I delete steps in XML (get.bin, sbl1, sbl2, sbl3, etc) the process just gets hung up and fails on the next step

Trying the most recent Matt's Utility, Mr.Parkinson's Utility, and SamuriHL's House of Moto (trying each build listed above) I get significant failed messages which I will post below.

Is the phone FUBAR or does anyone have a suggestion how I could fix this?
Spoke with the guy that gave me the phone. The update that bricked the device was 4-5 months ago. I'm guessing it was May for the kitkat update. He's not sure if it was running kitkat or jelly bean. It wasn't rooted and never was unlocked.

Sorry to be the bearer of bad news, just by looking at your screen shots, I can tell you it's hard bricked.

[Q] xt926 - help is appreciated

device: VZW motorola droid razr hd xt926 - completely stock, no customizing at all, every update that came to the phone I installed without problem.
About a month ago (~dec 16, 2014 I believe) the phone was lagging and unresponsive so I powered down, restarted, and that is when the problem began. Upon restart the phone got to the red motorola logo and would hang there. holding the power button would power down for a second, then restart.. so I soft reset it to the boot menu where it atleast wasnt heating up drastically. I left it plugged in because there was no way to power down. From there I began researching the xt926 and seeing other people's problems about the phone hanging at boot logo.
I scoured these forums (and numerous others) for problems similar to mine. Since I was able to get into the boot options menu I've tried everything I could find.. rsd lite, rsd flasher, motorola device manager, house of motorola, droid razr utility...
I tried for about 5 days straight and gave up, took it to a local cell repair place and asked what they would do to repair it. They mentioned a few of the things I tried and said that I had went further than they would go. Out of pity (I believe) they gave me an old BB curve which I've been using the last month. I've been shopping around lately for new phones and wanted to give the razr hd one last crack before relenting and getting a new phone (either S5 or HTC one M8).
First question I guess is, is the phone unusable and beyond repair? upon power up, the phone gets to the red motorola logo for about 2 seconds then goes to this presumed fail boot screen.
it lists:
AP Fastboot Flash Mode (S)
10.9B(*) (sha-61146a2, 2014-07-29 03:17:13)
eMMC Info: Size 16GB
Device is LOCKED. Status Code: 0
Battery OK
Transfer Mode: USB Connected
Load kernel (boot) failed
Fastboot Reason: Boot Failure
I can restart the phone from here by clicking the power button, it restarts, hits logo screen, then right back here.
I can get to the boot selection screen by holding the volume up button when its restarting.. it'll get to the boot menu and then restart after about 3 seconds of idle time if I dont pick something quickly.. the 5 options at the boot selection are:
Normal Powerup
Recovery
AP Fastboot
Factory
BP Tools
Normal Powerup, Factory, and BP Tools do nothing.. the phone restarts and hits logo screen then boot failure.
AP Fastboot restarts phone and goes to the same boot screen, but instead of the load kernel boot failure stuff it says: Fastboot Reason: Key Pressed. This is the same result as during powerup/restart holding the volume down key.
Recovery restarts, gets to logo screen, then after about 5 seconds gets to the droid dude with the red exclamation triangle over his open chest. From here I can get it into the recovery mode with 5 selections..
reboot system now
apply update from sdcard
apply update from ADB
wipe data/factory reset
wipe cache partition
All of that being said.. do I have any options to get this phone functional?
Your time and effort is greatly appreciated.
Cheers
I'm assuming that you tried the wipe data from recovery option ? And then to be clear did you actually download and install a factory image using RSD?
i would try rsd lite again with all the latest version of the fxz/sbf in case you were using an old one. this thread from @SamuriHL http://forum.xda-developers.com/droid-razr-hd/general/fxz-4-4-2-183-46-15-t2873083 is the latest for the xt926 make sure you have the moto drivers installed. if you need i can help with teamviwer or hangouts if you want just pm me for details.
as a side note i do not think that your phone is dead just soft bricked.

yes, I factory wiped and using rsd lite, droid razr utility, rsd flasher I tried many different images.. through different iterations and combinations. When rsd lite had no effect installing the different images I had, I moved onto a different program. I wasnt exactly sure which image the system required.. I went through the following:
VZW_XT926_4.1.1_9.8.1Q_39_VQW_CFC.xml
VZW_XT926_4.1.2_9.8.1Q_62_VQW_MR-4_VQW_CFC.xml
VZW_XT926_4.4.2-KDA20.62-10.1_CFC_1FF.xml
VZW_XT926_4.4.2-KDA20.62-10_1FF.xml
VZW_XT926_4.4.2-KDA20.62-15.1_1FF.xml
I am unsure if they are 'factory' images

I am glad to hear that the phone may have a chance yet. I will look into the latest image. I have RSD Lite v6.2.4.. could someone remind me of the basic flash process?
connect the phone to my pc
put the phone into fastboot,
load up rsd lite
load up image in rsd lite
????
profit?
Again, thank you for your time.
edit: I also have motorola mobile driver 6.4.0 installed
RSD Lite v6.2.4
VZW_XT926_4.4.2-KDA20.62-15.1_1FF.xml
When i click start it fails and gives status:

flash this in fastboot. use the data wipe batch file.
if the phone doesnt boot fully to the setup screen within 10min after flashing, its likely toast.
edit,
on second thought, dont close the prompt until you see if it boots up or not. if not, copy all the text from inside the prompt and post it here for me to look at.
thanks
The download is going incredibly slow, but when its done I will flash it and report back.
Thanks for the direction

so the download is crawling along.. it has finished prematurely a couple times already. I'll open the .rar and it says its incomplete.
Is this for matt's droid utility? I have a copy of it I got on 12/17/14.. with an fxz labeled:
VZW_XT926_4.1.2_9.8.1Q_62_VQW_MR-2_VQW_RSD
I'll keep trying the download from the link you provided in the mean time

Like I said, no modifications to the phone, it was lagging/hanging so I restarted it.. simply would not boot afterward..

From what I found on the internet, I guess you didn't turn on the setting `oem allow unlock' in developer settings.
But isn't there `rescue party' (a subsystem of androids recovery which shows two options: 1) Try again 2) Factory data reset)?
If it is, just press that Try again button, wait until it boots into rescue party again and then press the Try again button again. Do that 5-7 times in a row (depending on the phone). Your phone should detect that your current slot is unbootable and should boot into the unupdated slot.
You could also try to find the stock image (or whatever image you have currently installed) and flash it within recovery (there should be a button labeled like `update...' or `sideload...' or something). That should also work.
If nothing helps, you could also factory data reset and hope that it works now...
If that also doesn't work, you could research abit about edl (emergency donwload mode) and how to use it to reflash your device.
