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)¨
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.

I'll try, but, where I should do that? I'm kind of lost with all this.

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 had cynogen mod installed and my phone rooted. Then all of a sudden i get a boot loop. I tried to flash but I receive an error FAILED <unable to flash write>. im able to go into recovery and boot loader. In my team win recovery in the terminal I get multiple errors saying "E:unable to mount '/data", "E:unable to mount /ata/media/TWRP/ .twrps when trying to read settings file" ,"E: No valid storage partitions found for MTP" (when i try to enable mtp), "E:unable to mount '/persist" and "E:unable to mount storage"
PLEASE HELP
I have same problem. Internal storage 0Mb. Can not mount /data /cache /sdcard. Using TWRP still see /system stucture but /sdcard /data are empty.
I was used NRT to flash other ROM or stock ROM, but 50% partition flashing is Failed (can not write flash...).
So sad! It seems my Nexus 5's flash chip is dead or device partition table is corrupt ?

I looked into my partitions being corrupted but when i tried to repair them it said the file location didnt exist
Since you can boot into fastboot mode, did you try to flash the factory imgs? (except userdata.img to begin with).

Hi,
I have Moto G (XT1032) with Optimized Stock Rom 5.1 from this topic. It was alright couple of months, but today I woke up with my softbricked phone
It's stuck on Warning Bootloader unlocked, TWRP can't access any folder (although he see folder structure, so i guess it's good sign? :crying: ), all Internal Storage is displayed as 0MB, if I try to do anything I always get
Code:
"Failed to unmount '/system' /* /data etc. */ (Invalid Argument)"
Adb recognize device, but as unauthorized, when I start ADB sideload feature in TWRP, phone is recognized as sideloaded, but when i try to push rom it's say error: closed.
Can I somehow fix this phone, or is it permanent eMMC damage?
You have to give to Wipe/Format Data and Reboot/Recovery. Later go to wipe/avanced wipe and select: Dalvik/ART, cache, data and system.

I already tried it. I got spam of error Failed to unmount... and mkfs.f2fs error: "E:Unknown MTP message type: 1"
And Reboot/Recovery just shutdown phone, I have to get to recovery thru Fastboot (Power and Vol down).

Have you tried flashing unoptimized factory fimware through fastboot? To do this, enter fastboot mode and then flash the factory firmware for your device from here.
Do you have TWRP or Stock recovery?

Hmm... Possibly an issue with drivers, or incorrect factory firmware. Also, have you tried skipping GPT and motoboot.img?
