Hi everyone, I hope you guys can get me a hand with this issue.
My Moto G, is briked. Its with bootloader version 41.18 (Lollipop) and its imposible to downgrade it becouse I get this message
"(bootloader) Preflash validation failed
FAILED (remote failure)ยจ
But is only that command, all others commands to flash the phone work properly (but I dont have any clue why its imposible to make Lollipop works, and I cant make KitKat runs with an 41.18 bootloader)
At this time, I dont care any more upgrade to Lollipop, I just want my phone back :crying:
Please help.
Thanks for you time.
unlock phone
preflash validation fail happens due to the locked bootloader . Either unlock bootloader to skip boot flash validation checks or flash stock factory image without unlockingbootloader in recovery mode . Standard recovery and factory firmware image .
I had this problem, I eventually took it back to the point of purchase after trying EVERYTHING! Have you tried flashing stock ROM ignoring the preflash validation error?
Sent from my XT1039 using XDA Free mobile app
You would have executed the following command when trying to downgrade to KitKat:
fastboot flash motoboot motoboot.img
It should not be done. Nevertheless, try installing paranoid android via a custom recovery.
fastboot flash recovery cwm-*.img
Once you are on 41.18 bootloader, you cannot flash an older motoboot.img over the existing image.
Even with a Lollipop bootloader, you can flash all images and the phone should boot.
I have an xt1032 and flash stock 4.4.4 Retail US with no problem.

My bootloader is unlocked ("Status Code: 3"), but I cant flash the 41.13 bootloader, neverthles, I can re-flash the 41.18 without problem.

Yes, if I flash my Stock ROM (Retail LATAM) it's never pass the "Warning Bootloader", just keep there until I turn it off. If I flash an 5.0.2 Rom, when I start the phone, takes me back to the bootloader with "Boot up failed" message

The problem is that I cant flash any recovery, I try CWM and TWRP. Always gives me an errero when I try too boot in to Recovery Mode.
Are you flashing the correct recovery? Try the latest Philz for your model of phone. The xt1032 is also known as falcon.
What errors are you getting when trying to flash recovery in fastboot?

Yep, I try installing Lollipop firmwares with "fastboot flash ......" but no one work
I have an XT1040, and there isnt an official 5.0.2 for this version of Moto G, but it should works, no?

You were right! I was flashing a wrong recovery, I have XT1040 and for this one the name is "Peregrine", I already installed CWM and TWRP (both works, but no one read the SD Card)
I found an NIGHTLESS CyanogenMOD 12 for XT1040 but when I try to install it. I get this message (installing de *.zip with TWRP and CWM):
Code:
E: Unable to mount "/data"
E: Unable to mount "/cache"
E: Unable to mount "/system"
E: Unable to mount internal storage
Any ideas? :crying:

First, format /data/media
Then, /system
Then, /cache
Then, try to install the ROM.
Are you running GPE version of Lollipop on your xt1040? If you are, you may need to re-install stock 4.4.4, including flashing gpt.bin because the partition sizes may be slightly different between stock Lollipop and GPE Lollipop.

No, I dont install the GPE in the XT1040. Maybe could be what are you saying. Yesterday, I cant remember what I was trying to install and in fastboot, while I was flashing, said "Image is too large", but in de DOS windows on PC, it says "OK"
The issue is that I cant do a downgrade of gpt and de motoboot.
So, I should install 4.4.4 KitKat, (without flashing those 2 files) and try with the recovery installing CyanogenMOD 12? Or CMod12 not uses 41.18 bootloader?
Edit: I think that I cant install KitKat, bootloader gives me "Image is too large", the DOS windows says "OK", but Im thinking that really its not OK.
I install """succesfully""" an 5.0.2 Retail of Brazil, but for the XT1033 version. Really, I dont know if is GPE, but I was able to install all the files and the fastboot dont showme the "Image is to large" message.
Edit2: Withi is command in Terminal of TWRP
mke2fs -T ext4 /dev/block/mmcblk0p8

When I try to install the CyanogenMOD's zip, says "Unable to mount /system". So I think I fix the problem with /data. But if I'm right, now what?
Since your bootloader is unlocked and you never flashed a GPE ROM, go back to the start.
If you want to install a custom ROM, flash the recovery for your phone. If you get an error message in fastboot, write it down and post it here.
If you want to flash back to a stock ROM, are you flashing every partition except motoboot.img? Are you erasing cache and userdata at the end?

I cant flash any stock ROM for my phone yet becouse, stocks ROMs are until 4.4.4 KitKat using bootloader 41.13. and y cant downgrade my 41.18 bootloader
I am trying to instal CyanogenMOD 12 from my recovery (CWM and TWRP works properly) but I get this message
Code:
"E: Unable tu mount /system"
Here is a photo of the error

Edit: I try "fastboot erase system" and "fastboot format system"... Both are done succesfuly, but I stil geting the same error. (Also, I cant mount /storage/sdcard1)
Where did you get the Lollipop bootloader?
Did you try to use fastboot or mfastboot to flash a stock ROM. I have an xt1032 with 41.18 and I can flash stock 4.4.4 ROM.

I get it when I flash with fastboot an firmware from Brasil wich have 5.0.2.
I will try installing the firmware you have, could you paste me a link please? Is with Recovery installation or with fastboot?
You need to download the stock 4.4.4 firmware for your phone and follow this guide: http://forum.xda-developers.com/moto-g/general/restore-to-kitkat-lollipop-moto-g-t3011553
Did you install the right recovery? Try using Philz for the peregrine to install custom ROM: http://forum.xda-developers.com/moto-g/4g-development/recovery-unofficial-philz-touch-t2827332

I followed the first guide and in the DOS window where you put the commands "fastboot flash...." everything goes "OK", but in the phone, the fastboot says "Image is to large" when is going to flash the "system" so Im thinking that its not flashing really
After reboots, the phones dont go further than "Warning Bootloader Unlocked"
I installed Philz for Peregrine, I try to install 2 customs ROMs differetns for XT1040 and I get
Code:
Opening update package...
Installing update...
detected filesystem ext4 for /dev/block/plataform/msm_sdcc.1/by-name/system at /system: invalid argument
unmount of /system failed; no such volume
detected filesystem f2fs for /dev/block/plataform
E: Error in /tmp/update.zip
(Status 1)
Installation aborted.
I 'm about to give up
After flashing the gpt.bin file, type fastboot reboot-bootloader and continue flashing. Maybe this will help.
did you find a way to fix it yet?
im having the same issue. and not able to do anything, i tried flashing cm12 didnt work.
I'm having some issues installing/flashing twrp on my Nexus 5. I have been trying to fastboot twrp but it doesn't work, it says it's successful but I don't have twrp. (know what I mean?) I then tried to sideload Superuser so then I can download twrp manager or flashify and install it through either one, but when I do I get an error saying:
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted.
I am out of options. I do have my bootloader unlocked if that matters.
After flashing twrp, are you booting directly into recovery from fastboot?
You can boot directly into TWRP without flashing it, with
Code:
fastboot boot <your image>.img
Does that make any difference?
Hello,
I was facing a lot of issues with my YUPHORIA. So, I tried to flash it using the official instructions on official forum using Fastboot.
The flashing got stuck when it was trying to flash the "system" partition. I disconnected the cable and tried the flashing process again.
Now, I am able to flash everything else except "system"
It is giving an error -
"FAILED (remote: flash write failure)"
ADB is not detecting my phone.
QFIL is also showing "No Ports Found"
However, Fastboot is working fine.
I donot have TWRP on my phone as of now.
Please help !
I am having exact same problem. Were you able to find solution for it?
Same issue here
Did you get the final solution?
I cant not flash system.img to my softbricked Yu Yuphoria 5110 even with the latest version of adb and fastboot and even with the -S option! Nothing works! Can't flash only system.img, other images are getting flashed. Pl help!

My story:
I couldn't get any update from Settings>Update. My phone was EMUI4 (Android 6). I wanted to EMUI5 (Android 7). So I used firmware finder in phone(I mean, it's not windows app, it was android app). I thought me to need to install it version by version. So first, I selected b202 (there was it after b198) and I used to proxy to install. The phone downloaded the firmware and rebooted itself. When installing (It was %2), rebooted again. And now my phone is boot-looping.
Detail:
I can install TWRP or stock recovery via Multi-Tool 8. Also fastboot is working.
Note:
-Stock recovery dosen't install update.app from sd-card. Because (vol-)+(vol+)+power dosen't run the installer. The recovery is opening when I click those keys.
-Stock recovery dosen't have "download&install" option. Ability options: "Reboot system now", "Wipe Data/factory reset", "Wipe cache partitions". ("Wipe Data/factory reset" dosen't work.)
-Also I tried this guide. But I have error thats:
"Failed to mount '/3rdmodem' (Invalid argument)"
"Failed to mount '/cust' (Invalid argument)"
"Failed to mount '/data' (Invalid argument)"
"Unable to mount storage"
-TWRP says that "No OS Installed!"

So, I don't know what I will do. DC-Phoenix is not free. But if it will be fix, I can buy.

No you are wrong, I can access fastboot but the phone dosen't let me do anything. For example, now I getting hifi error. I'm trying this: "fastboot hifi FW_HIFI.img" or "fastboot erase hifi" and the phone is responding: "FAILED (remote: Command not allowed)".
My phone is unlocked! But I can't do anything whatever I want.

Alot tools (aka, Uni-Android Tools) need to access phone via ADB. In fact, if I can connect the phone via adb or COMport, I can do everything.
So if you know how to do "flash the update.app via fastboot", tell me please. But I don't think do it with basic tools.
bro, i,m also talk about fastboot mode flash, yes its possible, you can download UAT crack , goto huwei section, select huawei flasher, select update.app file, hold VOL _ connect power cable its must be in fastboot mode, now Press start flash, thats it
