[RAZR HD Q&A, Help & Troubleshooting] Xnt13:
Hello,

I have a similar problem.

The phone was purchased in Germany, then unlocked via the website of Motorola, has been updated to 4.1.2 (9.8.2Q-8-XT925_VQUL-1601), then updated via OTA to 4.4.2. The latest firmware was 180.46.119.XT925.O2.en.DE KDA20.119.

And everything was fine, but one morning the phone turned off, although the night was a 93% charge. When I turned on the phone, the phone wrote this (see attached):

Device is LOCKED. Status Code: 0

CID Read Failure
Invalid CID status 0x69
No valid PIV block in SP for system
piv validation failed (system)

When I try to flash files gpt.bin and tz.mbn from 4.1.2 O2 en.DE

displays the following error:

fastboot flash partition partition_signed
(bootloader) Variable not supported!
target reported max do' (19wnload size of 31457280 bytes

(bootloader) Preflash validation failed

finished. total time: 0.101s

At the same time the phone screen shows:

downgraded security version

update gpt_main version failed

preflash validation failed for GPT

And if I try to flash files gpt.bin and tz.mbn from XT925_rcica-user-4.4.2-KDA20.117 or Blur_Version.180.46.117.XT925.CEE-Retail.en.EU then it shows another error:

And at the same on the phone screen is nothing changes.

I could not flash the firmware 4.1.2 (9.8.2Q-8-XT925_VQUL-1601_USERSIGNED_S7_USAVANQUO2DE02C.0R_LSAVNQJBO2DE_P014_A004_CFC.xml) via RSD, even removing rows from xml file. Through Hose Of Moto failed too. :( I think I need gpt.bin and tz.mbn files from OTA update 180.46.119.XT925 KDA20.119.

I have exactly the same but working xt925. Here's what command "getvar" shows from a bricked phone:

fastboot getvar all
(bootloader) version-bootloader: 109B(*)
(bootloader) product: vanquish_u
(bootloader) secure: yes

and that from the working phone:

I have over seven days trying to revive the phone. Please help me, I already broke my brain.

Ps .: And one more thing ... where xt925 recorded CID? I have not found mmcblk1p18 on it.
