WARNING MOTO G 2nd GEN USERS PLEASE READ

I Have noticed quite a few - as in 3+ Moto G 2nd gens's are having problems with corrupted partitions, i.e OTA fails to install half way through or cant install via Mfastboot and / or Custom recoveries.
Due to the corrupted partition (or rather partition table) IT wont allow flashing / erasing or clearing / factory resets
There's no proven cure but MAYBE locking and then unlocking boot loader again may fix this as it WIPES data.
AS a Precaution I suggest anybody that who is thinking of upgrading / downgrading or restoring does a FULL FACTORY reset AFTER they have backed up phone.
Yes its extra work but with memory cards being cheap and playstore / google accounts backing up your apps, contacts etc, it's simply lazy and Dangerous Not to backup....

so...
my moto gave up during OTA update to 5.0.2 -> flash and rebbot OK, but "optimizing applications", took an eternity, then (in the middle of the job) the screen went black.
after a cold reboot it finished and everythings allright now..

My Moto G has this problem too!
The userdata and cache partitions seem to be corrputed as they give the error: blkdiscard on partition /dev/block/platform/msm_sdcc.1/by-name/userdata ( /cache )failed
This happens in stock recovery.

Help
I have this Problem too.I was in lexodus Rom then my phone shutdown,then i Turned it on and all apps fc's .I tryed to flash it With twrp but it cames an error execute update binary .I cant restore or wipe anything .And when i try to restore it with you stock Rom installer in succes but it still the same rom with the same Problem .I need help Please PS sorry for my Bad english

When the partition table is completely hosed, you can't lock the bootloader, only unlock. And unlocking in this state does not wipe it.
There is no recovering from this state, and honestly you get what you pay for with these phones.
When the battery drops below 5%, there is a high probability of the eMMC being ****ed in this way (I have had it happen on 4 phones now!). Undoubtedly a major design flaw.

I messed up partitions on my oneplus one. Most specifically the data one trying out f2fs. I was able to recover the partition by formatting it with a combination of philz cwm, twrp, and parted. I don't remember what I did as I was desperate to fix my oneplus. You can look into learning how "parted" works and you may be able to reformart the partition through adb shell.
I know this is a bit of hogwash help, but I was able to recover my /data partition.
Edit: also if I understand correctly, just because your partition table gets effed up, doesn't mean your recovery doesn't contain the proper information to put it back properly. I was able to boot my phone into temporary philz and twrp by command line using fastboot. I'll see of I can find some info.

Here is the command to boot a recovery img from fastboot
fastboot boot customrecovery.img
from there, you can try to use philz to format your partitions, or TWRP. Which ever recovery works for you. Then, presumably if this works, you should be able to restore your device to factory or install a custom recovery or rom.

In twrp i can Format all expect infernal storage .when i Format data it says OK but the data is still there and When i try to boot philz cames a bootloop

You can't boot a recovery with that command when the moto g is in this state sadly.
Code:
C:\android\platform-tools>fastboot boot twrp.img

booting...

Literally the only thing you can do is unlock the bootloader (and not lock it again), and sometimes access the stock recovery (where nothing works).
The only hope of recovery is the MBM-CI (qualcomm blank flash programmer) files, which motorola keep to themselves. For this reason, buying a moto g is risky.

Also no Chance to recover our moto g ?:crying:

I'm on the same boat, but actually when I try to boot, it goes in an endless bootloop of a Motorola logo (not the animation particularly). I've tried only with TWRP. I'll try later with CWM.
Flashing goes well but.... crap, I hate this

So if i unlock bootloader and root phone will i be at risk?? Or i am only at risk if i mess with partitions or try to lock bootloader again?

How come "qualcomm blank flash programmer" will affect on eMMC?
lol'd..
Nor the unlocking\locking will work in this state.

Am enthusiast of device-modding, IT-engineer and a big fan of Motorola phones since 2005.
Of course I understand.
I mean this tool could help somehow by taking part of restoring, but supposed to fix issues over WRITABLE memory.
In case of RAW partitions - should delete partition table and recreate then, since plain format refused.
Anyway, my point was about this tool - it's not classic HardBrick state, Bootloader is working thou. We will use flasher if we'll replace eMMC-chip, for example

Erased phones recovery

Hi I have the XT1570, running unlocked and with rooted but stock 5.1.1. I have run in to some issues with the recovery part.
Firstly I wanted to go back to the recovery and flash a stock recovery so I could get the OTA for MM, i did that using fastboot, and the flash worked fine according to fastboot, however once i rebooted into recovery it would not load, got an error message, I forget now something about dumping back to bootloader.
Anyway i fixed it got TWRP back on again, then tried a different stock recovery, same thing same error, so i thought I would easily get back to TWRP by the same method, flash again. I was wrong, now fastboot told me , target reported max download size of 536870912 bytes
error: cannot load 'twrp-2.8.7.1-clark': No error
Remember this is the exact same TWRP image i have just flashed not 5 mins before.
So i thought ok then, maybe an old image is in there taking up space or something.
C:\Users\David\Desktop\Mfastboot\Mfastboot>fastboot erase recovery
erasing 'recovery'...
(bootloader) Erase allowed in unlocked state
OKAY [ 0.017s]
finished. total time: 0.019s
Now I get the message:
Invalid boot image header.
Error:failed to load kernel
Boot up failed.
I presume I have deleted everything in the recovery partition, and so messed it up good, but I dont know how to fix it at this point.
I also erased the cache along the way (via fastboot) as I tried to get the OTA update to work anyway just to see what would happen, so I had to erase the cache to cancel updates
I must reiterate, I can boot into Android and use my phone no issues, at all, just I have no recovery at all and this means updates arent going to work, also i cant seem to find a reliable source for a stock recovery.
Some step by step help would be appreciated, as I am not an expert by any means on this.
Thank you.

Also my device was bought in China as that is where I am, it does indeed have the code name XT1570, dual sim, I would assume it is basically the same as the XT1572 asian. I do also have an original backup of the phone after unlocking bootloader, before root, which was my next port of call after changing the recovery back to stock.

fixed it i was just being foolish, someone delete this thread it is of no use.

Can you explain how you fixed it? I too have deleted the recovery in an attempt to flash twrp, but now neither twrp nor the stock recovery are there?

[GUIDE] LG G STYLO How to root the T-Mobile 6.0 update

This guide was made before Kingroot was able to root the official update. But thanks to @oskar and @TheDerekHarper on XDA and to @josephwv on Android forums it is now comfirmed that Kingroot will root the official update. But first you must still follow steps #1 through #6 so Kingroot can root your device.
Now before Kingroot was able to root the update I figured out how to root the official update and it is not all to complicated. The following guide will walk you through the root process. But I am not responsible for anything that happens to your devices by using this guide as you are responsible for your device.
What you need:
1. A computer running Linux or Windows with adb and fastboot installed. (I used Ubuntu)
2. If you are using Windows you need all the drivers for your device installed. Linux users will not have to worry about this.
3. A functioning USB cable for your device.
4. Battery charged at least 50% just for safety.
5. The TWRP revovery.img, this is the same TWRP recovery we already have for the LG G Stylo I have just renamed it to recovery.img to make it easier to type the name in while typing fastboot commands.
6. The SuperSU-v2.65-20151226141550.zip by Chainfire. (All credit to Chainfire for this awesome zip.)
How to root your device:
1. I suggest you first go to Settings/General/About Phone/Software info and tap on the "Build number" until it says"You are now a developer". Then back out of until you are in Settings/General and go to "Developer options" and turn "Enable OEM unlock" on. This is to allow TWRP recovery to be able to boot. Also turn on "USB debugging" while you are there.
2. Download the SuperSU-v2.65-20151226141550.zip to your device. You need to move the zip file from your Downloads folder to somewhere on your external SD card as it will not be deleted from there when you use the "fastboot oem unlock" command in step #6.
3. Download the recovery.img to your computer. If you do not have adb and fastboot setup globally for linux or in your path for windows you need to move the recovery.img to the directory your adb and fastboot is in and open a terminal or command line (depending on your OS) in that directory or cd to that directory. If you do have adb and fastboot globally or in your path you can just open a terminal or command line in the directory you have the recovery.img or cd to the directory you have the recovery.img.
4. Once you have the terminal or command line open run the command "adb devices" to make sure your devices is detected by adb. You may get a toast pop up on your device asking if you to "Allow usb debugging". Except this as this is the RSA key you need to allow your computer to communicate with your device via adb. You should see something like "LGH631dffacad9 device" in your terminal or command line. If you see "unauthorized" instead of "device" you have not excepted the RSA key.
5.Now type the following command in your terminal or command line. Type "adb reboot bootloader". This will reboot your device to fastboot mode. Once in fastboot mode use the "fastboot devices" to make sure your device is recognized by fastboot. You should see something like "dffacad9 fastboot". If you are in Linux and get a error message you may have to use "sudo fastboot devices" for fastboot to work. (If you are using Windows and are having trouble with fastboot recognizing your device you need to install the device drivers. If it still does not work install the drivers again with your device connected to your computer in fastboot mode.)
6. To fully unlock your bootloader you have to use the command "fastboot oem unlock". You have to do this or this root method will not work. But be warned that if you do use this command it will factory reset your device. Plus you will get a line of text saying the bootloader is unlocked on the splash screen when you boot your device.
6-1: If you are wanting to use Kingroot to root your device you can reboot your device now. Open the Kingroot app and let it root your device and then use Flashify, Rashr, or a similar app to flash the recovery. Then boot to recovery and flash the SuperSU.zip in recovery and it will remove Kingroot and have SuperSU installed on your device.
7. Now you can do this two ways if you do not want to keep the stock recovery you can use the command "fastboot flash recovery.img" to install the recovery and then use the command "fastboot reboot recovery" to boot to the TWRP recovery. (If this command gives you issue like it seems to be for many then just use the the following method and then use Flashify or Rashr app to install TWRP after you are done rooting.) If you want to keep the stock recovery you can use the command "fastboot boot recovery.img" to boot to the TWRP recovery.
8. Once you are booted to the TWRP recovery you should make a full backup first so you have a backup to restore to in case things go bad. After you make a backup then select install and then find the SuperSU-v2.65-20151226141550.zip and install it. Once it is installed reboot your device to system. If TWRP gives you a warning about the su binaries missing and asks if you want to install thee su binaries before you reboot select no or it will interfere with the rooting process of the SuperSU.zip. When your device reboots it will boot to the LG splash screen and then reboot again. But then it will boot to the OS but it will take a minute. Make sure you let your device reboot all the way to the lockscreen or home screen depending on if you have a lockscreen enabled or not. You should be fully rooted after this, enjoy.

Resserved in case needed later.

Thank you.

Just go go KingRoot.net, download their apk, install and run the root program. Igll work out of the box after, sadly I couldn't get the above method to work either with super su.

do the fastboot boot recovery.img so it boots up twrp then flash the supersu zip then boot your phone you should be rooted then flash twrp using flashify

I was getting the same error, ( in step 7 don't flash the recovery )
just use "fastboot boot recovery.img" and it will boot to TWRP without installing it
you can then install SU, ( note ) when you exit or re boot from TWRP it will say SU in not installed do you want to install it, I did the first time and it seemed to hose up, so I did everything over and the second time selected no to re install.
once booted I used flashify to install the TWRP img, and I am able to boot to recovery using Quickboot apk
on a side note I have SU installed, I can use root explorer and other apps that ask for SU access, but Titanium backup
doesn't seem to uninstall apps anymore, they seem to re install after a reboot
Hope this helps yall's

I gotta be honest... I'm pretty skeptical to try it. I've read of everyone having either a softbrick boot loop or the root just not staying after reboot. Yours worked for H631 T-mobile 6.0 and stayed? If you confirm T-mobile variant and 6.0 I'll try it. There's a lot of headache with this method for me (not saying it doesn't work). I bricked my phone trying to get the binary files for SU by trying to reroot. But unbricked it with LG Flash Tools and a stock kdz. So I don't want to brick it again twenty minutes later lol

Made a tutorial on how to get the marshmallow update (i.e. rom i've used.)
And then afterwards i downloaded Minimal ADB & Fastboot, OEM Unlocked the device (for safety) and downloaded the Kingroot Apk.
Installed it, and just allowed the program to root. It was pretty simple, haven't had any issues (i've even disabled OEM Unlock from the phone & USB Debugging.)
Hell, even adoptable storage is enabled for my phone too (but that's another tutorial from somewhere else.)
I do plan to make a root video, just so someone could see it and grab their opinion.
To be clear: I'm using a metroPCS LG Stylo. Also, only time the phone had issues was when i factory reset it to get rid of root. (didn't work)
so i had to follow the steps from the above tutorial to reflash the stock rom.

well this did it, the root actually worked.

I got a permanent root from the procedure listed on page one of this thread. The only thing I did differently was, when booted into TWRP and you try to re boot the system you will get the question if you want TWRP to install root. If you do allow TWRP to install root, you wont get root. At this point select the option to just reboot the phone. The LG Logo will appear twice before it fully boots. When the device is fully up, you will have root.

My apologies as I made a typo in the guide. The correct command is "fastboot flash recovery recovery.img" to flash the recovery. I will fix this along with another rework about putting the SusperSU.zip only on your SD card.

I do not know if you can use it or not as I do not have that device. But you can try it bit if your device does not boot to fastboot mode when you issue the adb reboot bootloader command then your device's bootloader is not unlockable and this root method will not work for you. But from the posts in this thread point out that Kingroot now works on the 6.0 update so you can also try Kingroot to see if it willroot your device.

Is there anyway to do this without wiping your data from 'fastboot oem unlock'? My bootloader keeps saying locked in fastboot mode even though I checked Enable OEM Unlock in settings. It won't let me boot the recovery.img because it's locked.

Hmmm looks like maybe fully unlocking the bootloader enables all fastboot commands. You can try downloading and installing Kingroot and root with it as the posts here comfirm it will root the update now. Or just u lock the bootloaderb but your device will be reset if you do.

What if we just enable oem unlock in both the system and the bootloader then use adb to push the recovery, superuser, and busybox to the system. King Root caused too many system instabilities, it had injected itself as a system app and after unrooting and uninstalling after a reboot I was left with a soft brick due to a secure boot error 1003. A stock 5.1.1 kdz and the lg flash tool was able to bring my Stylo back to life.
It could all be done by running a simple batch file bundled with everything we need for our device. Linux would probably be the better option but it could work the same in windows.

Please give some help.

Reboot to recovery first after flashing twrp. Then reboot from twrp recovery.
Don't worry about the message. It's just a warning.

do exactly what i give-
1.Put your device in bootloader mode(make sure the usb debugging is on)
2.Open adb (make sure adb and twrp are in the same folder)by shift+right click,then open command window here(do this where adb is installed).
3.Type: fastboot flash recovery [name of twrp image].img
4.Then in the bootloader menu toggle to restart bootloader .(Not restart because the recovery will get replaced by stock recovrey)
5.Open recovery.twrp should be installed
If you have any problem send the printscreen of cmd.

Step 4 : Choose Reboot to recovery mode using volume keys. Press power button to select.

First of all, thanks for all the reply.
I will leave more detail and keep trying.
turn on usb debugging. --> ok
adb reboot bootloader --> ok
fastboot devices --> ok show devices
fastboot flash recovery recovery.img --> enter everything right but only got fail & pain T_T
// The message:
fastboot flash recovery twrp.img
(bootloader) has-slot:recovery: not found
target reported max download size of 536870912 bytes
sending 'recovery' (12496 KB)...
OKAY
writing 'recovery'...
(bootloader) Image not signed or corrupt
OKAY
// end
Here, it said sending 'recovery' (12496 KB)...
which means, I guess it get that img file, but still fail.
By the way, some other user got the same problem and message.
I tried on XT1625 Moto g4, again and again, fail. close unnecessary program.
If I can unlock bootloader, hardly believe things could go south like this.
Maybe the key problem is
1 (bootloader) has-slot:recovery: not found
something must wrong, but where?
2 (bootloader) Image not signed or corrupt
XT1625 Moto g4, Moto g4 plus need different TWRP? But there's only one from TWRP official website.
I tried everything I can do, download again compare with md5 before I post.
I can't find way out.
Anyway, thanks alot.

updated, I'm not sure, but as you said, I tried again, suddenly, I could enter TWRP, I will try whether it work or not.
Another question is, after unlock bootloader, install TWRP, root. Can I update system or patch with OTA?
Thank you for reply and help.

TWRP on Nougat

I saw where someone said you could flash B20 bootloader and flash TWRP on Nougat, is this true? Is anyone working on a guide for Nougat TWRP and root. On another note I thought that I read that ZTE would be bringing Wifi calling for Nougat with carries such as T-Mobile? I was unable.to find it under options and assume that it is not possible, anyone have any idea about this.
Thanks

I have an unlocked BL and recently upgraded to Nougat, but when I try to reinstall TWRP via fastboot flash method, it fails. I have tried two different versions of TWRP 3.0.3-1 & 3.0.4-1. This is the message I get.
PS C:\adb> fastboot flash recovery twrp-3.0.4-1-a7.img

Any ideas?

I got TWRP 3.0.4 installed (as well as 3.0.3-1)... It installed sucessfully via Fastboot for me, I even flashed SU, but I couldn't get my phone to boot into the OS (tried with and without SU).......It just hung at the boot pre-boot screen (where it warns you the bootloader is unlocked). I'd restart it, and it always hangs at that screen..... Only way to fix it was to boot back into TWRP, revert back to B29 (using DrakenFX guide) and then update to Nougat again. I spent about 16 hours straight working on this on Tuesday, before I gave up and decided to keep it stock until a custom ROM comes out, soon (Z.A.D. v.4), hopefully?

I have an issue where I installed B15 but whenever I boot my phone, it hangs on the Linux Tux logo. Any fix?

You probably pushed the power button to "Start"? Try letting it sit there about 10-15 seconds, if it won't boot...This is the exact same problem I had. I had to go back to B29, then do the update again. There is now a B15 "return to stock" walk-through, that may be the quicker route.....But I know returning to B29, turning on OEM Unlock in Dev options and then taking the update via your SD card was what I did (3 times in one day).

If my bootloader is already unlocked, can I skip that part (the 2nd link)?? Or is it necessary?

Those steps are meant to unlock the bootloader.
You don't need any of it. You already have TWRP (skip step 1) and bootloader unlocked (skip step 2) so yeah...
What do you want exactly?

My bootloader is unlocked (back when ZTE actually provided the unlocking)....adb fastboot works on my phone as well and I've flashed TWRP (3.0.4 and 3.0.3-1) and it's booted into TWRP, but I cannot boot into the actual OS...My phone goes all black and just hangs there, I think this may be booting directly into EDL mode and not the OS? I can plug my phone into the computer and my computer makes noises as if a USB device has been attached, but my screen is completely black. If I push the start button while the phone is booting (to bypass the bootloader is unlocked warning screen), I boot to a small penguin screen.
The only thing I can do from there is revert back to stock B29, then update back to stock B15.
I want to be able to install TWRP, root my phone, on Nougat, and be able to use my phone too?

I think I know what happened to you... did you by any chance allow system modifications in TWRP? That makes the OS bootloop if you have Nougat.

The MiFlash program found my phone, but failed every time I ran it.. So, I just bit the bullet and downloaded the latest TWRP 3.0.4-1 and flashed that.....And it worked! I then flashed SU, my fonts and changed my Emoji's....I'm about there with customization, and it's all booting up just fine!
But, yes the first few times I did allow system modifications......But I also did this last time too and it's working fine?
