Help Neeed Putting CM12 on Moto G 2013 - Moto G Q&A, Help & Troubleshooting

EDIT
-------------
Thanks for the support from the people below but I have now solved my origonal issue. TWRP didn't seem to be working with me so I downloaded MOTO G 4G/Peregrine Easy Recovery (Credit to the absolute legend who made that) and then installed ClockworkMod instead, which worked perfectly. I have now succsessfully installed CM12 onto myMoto G 4G. If anyone has the same issue and want's some help, just message me.
I am trying to get CM12 into my Moto G 2013 (xt1032) and have hit a problem which I don't know how to solve. I successful unlocked the biitloader on my phone, and attempted to root it. After many different methods, I finally got my phone rooted (not sure which method actually did this) however, I also tried to install TWRP on my phone, and I now don't have a working recovery on my phone.
I have tried all the root apps of installing a recovery, as well as 3 or 4 similarpc methords and non seem to work. I either get the no command screen, or the failed to boot error. If anymore detail is needed, just ask.
If anyone has any ideas on what I can do, I would be very grateful. My desired outcome is to either have TWRP or the Stock Recovery Working and also a working methord on how to install CM12. This is my first time at rooting a phone so please be considerate of the language used in any responses.
Thanks, Dan

I usually use fastboot and a PC but if you are wanting to use an app and are already rooted I have used TWRP manager available in the play store with out issue

TWRP manager is the solution, but I gnrally recommend you to do it using fastboot on a pc

How would I do this? I have fastboot already installed if that is what I need.
Also, what can I do to get the default 'recovery mode' back onto my phone. At the moment, I just get an 'Unable to Boot' error pop up.
Thanks for the quick reply.

You just need to download recovery file on your computer (I recommend it), boot to bootloader, either by using adb reboot bootloader or by holding Volume Down & Power simultaneously. Then you have to connect phone to your PC (if you haven't done it yet) and flash recovery using fastboot by command "fastboot flash recovery your_recovery_image.img".

After doing this with TWRP, using the same method, I get an 'Unable to Boot' message. I have now however descovered MotoTool AIO and Moto G 4G EasyRecovery which I will try. (Credit to all developers who created that software)

UPDATE!!
I have now fixed my issue and have CM12 installed. Please read the edit in the first post for more infomation. Thanks to everyone who helped.

[Q] Moto G 4G xt1039 recovery and root problems

I unlocked my new Moto G 4g xt 1039 (Android 4.4) without problems, but i cannot get it to accept any recovery i try to install. I tried manual adb with CWM and TWRP. I also tried the Moto Tool AIO and Easy Recovery.
All of them failed to flash the recovery except once when the recovery was flashed, but after booting it, it did not react to keypresses and touch.
I'm on Windows 64bit nad flashing every other device i have and had wasn't a problem.
Does anyone have an idea. Every thread regarding the device was more or less outdated so help would be appreciated. I like my devices rooted.
Just a short update and push ? Chainfire root worked. Still no success with recovery though.

Are you using a recovery built for peregrine?
Try one of the TWRP versions by @Somcom3X found here:
http://forum.xda-developers.com/mot...ection-somcom3xs-experimental-corner-t2996266
Yes, i've also tried to flash one of @Somcom3X recoveries, too.
The problem seems to be one of my previous attempts to flash a recovery, because i get two messages on the phone in fastboot mode when trying to flash a recovery:
cmd : getvarartition-type:recovery
cmd : getvaar:max-download-size
I'm pretty sure there should be at least two more lines after that, when sucessfully flashing. To me it seems as if the recovery partition seems to be broken. Any idea how to fix it. If iit is the problem at all.
I already tried reinstalling the stock recovery with Moto Tool AIO. Iget the following ooutput on the phone:
cmd : getvarartition-type:recovery
cmd : getvaar:max-download-size
cmd : download:00a00000
cmd : flash:recovery
bab check failed for recovery
Have you tried booting the image? Fastboot boot xxx.img
Sent from my XT1045
I tried now. the upper third of the screen is white and the two lower thirds are blue for a moment and fade to black with backlight on.
Update: For reasons beyond my knowledge it works. I cannot get it to boot to recovery from the fastboot menu, but it works with adb command boot recoveryxxx.img and from within advanced boot menu.
Friends, made ​​unlocking the bootloader and used the kingo root and the procedure was successful
XT1039
Android 4.4.4

Can only load bootloader Original Moto G

I have given up, which is why i have finally made a post.
At some point yesterday, I screwed up my phone. I wanted to root it, and install a rom, all of which I've done before. I unlocked my bootloader no problem, and followed these instructions on how to root. All done without a hitch. I was able to boot my phone, acess the play store etc.
Somewhere along the lines of trying to install either, CWM or PA, I can't remember which, I'm sure a process failed, and didn't take notice.
At this point in time, I can access the bootloader, my phone is recognized in fastboot but not adb. I have installed and tried every option under the tools/utility section, all which have failed to place a stock system in place. Ive downloaded numerous recovery files, and installed via fastboot, but I just get a blank screen, And that is what happens EVERY. SINGLE. TIME. when I try anything.
PLEASE someone point me in the direction needed..
I have used this guide, this one, among others here on XDA. I've installed reovery images from twrp via fastboot. All with no avail. My OS was 4.4 before i screwed my phone.
My last attempt was using falcon_boost_user_4.4.4_KXB21.14-L1.57_57_release-keys-cid9.xml.zip
tldr; Can access bootloader, fastboot yes/adb no, all avenues explored, can't fix phone.
Fixed. Sorry

[Q] [HELP] Unable to succesfully install ANY recovery

After trying for over three hours, reading what seems like all threads on the whole of xda and some other sites... i am ready to eat my phone. Ok, must get myself together :-/ . Here we go.
Specs:
Moto G 4g on dutch carrier (vodafone), XT1039
Situation:
Came from completely stock lollipop system, then succesfully unlocked phone via motorola website using the fastboot proces. Intending to install custom rom, first need a recovery. I am now stuck at this step. When booting i now get a screen "warning bootloader unlocked" before the moto splash begins, this is normal as far as i understand.
Problem:
Unable to boot into recovery. Directly after flashing any recovery (with fastboot) and choosing "recovery" from the bootloader i get the message "boot up failed"
After restarting the phone and choosing "recovery" from the bootloader i get the android on its back picture stating "no command"
Already tried:
installed the android sdk, fastboot and mfastboot.
Am able to send commands to phone with (m)fastboot. Flashing works.
I flashed: openrecovery twrp 2850 xt1032, clockwork 6047 falcon, philz touch 6587 falcon, twrp 2870 falcon m stock, twrp 2801 titan v2 and twrp 2860 xt1032
all give exact same result
"fastboot boot NAME of IMAGE"
"fastboot erase userdata & cache"
"fastboot erase recovery"
did the above things in any imaginable combination
I hope someone has some fresh suggestions for me? Thanks for your time.
Bro as far as I know the recovery is not installed u should install twrp from this thread the one on the official site gave me soft brick
Now about the dead android with no command shows that you are on stock recovery and u have booted into it successfully to go further into stock u have to press power and volume up at the same time (like u lock ur phone) but it won't help in installing anything try the recovery I linked (first format your phone complete data and cache wipe from stock recovery not necessary actually) install it through fastboot command and let me know if it worked (with thanks button) BTW what's ur bl ver
thanks for your fast response faizxy, as stated i already tried the one from that thread (i did not use the identical interpunction to describe it but to be clear it is twrp-2.8.7.0.-falcon_M_STOCK.img)
Where do i find my bootloader version? It is the one that came with the device, factory issue...
Some extra info, that might anwser faiz' question: when i boot the bootloader it shows:
"AP Fastboot Flash Mode (S) 41.1A (sha-80481ae, 2015-04-10 14:30:28)
Hope you guys will forgive me for bumping a bit soon, but I really hope some one has a solution! Tomorrow I have time to tinker some more
Have you tried at least one recovery that is actually for your phone (peregrine)?

Ah. I guess not. Did not know that there where recovery's specifically for the peregrine/xt1039. I searched for "moto g" but apparently is wrong model. DOH!
Thanks for helping out! My problem is solved.
For future reference; finding working pergerine recovery was quite difficult; most mirrors are down. I found one here: https://wiki.cyanogenmod.org/w/Install_CM_for_peregrine and then under header "installing recovery.." under step 2 the download link (i avoid deeplinking)
This one seems to work for me. Now lets find a nice custom rom!
The ones listed here http://forum.xda-developers.com/moto-g/4g-development/progress-twrp-2-7-1-0-source-t2807585 dont work for me. One gives black screen, the other one shows an unlock slider which is unresponsive.

Completely stock OnePlus One stuck in bootloop after latest CM OTA update

Hi everyone,
I'm hoping you can help me. I've had a OnePlus One since August 2014, completely stock. Never modded it, never 'flashed' anything, never installed anything outside of the Google Play Store. Always installed the official OTA updates as they pop up on the phone itself. Basically a reeeeealllly boring android user!
So Thursday morning (09/06/2016) I got a notification that a system update was downloaded and ready to install. Clicked install, the process began, phone rebooted as per usual. However, on the install progress screen (the green android with the spinning cogs), about one third of the way through the phone freezes. About 20 seconds later the phone reboots itself and then tries to install the update again. Freezes. Reboots. Tries to install. Freezes. Reboots. Tries to install.... I think you get the idea. It was doing this for a couple of hours before I checked it.
I'm moderately tech-savvy but never really got involved with android modding, rooting or flashing. So I'm a bit confused as to why my completely stock phone is stuck in a bootloop after installing an official CyanogenMod OTA update. The current status of my phone is that I can only boot into Fastboot mode via VolUp + Power. I can get my computer to detect my phone in Fastboot mode, however it informs me that my bootloader is locked. Attempting to boot into recovery mode via VolDown + Power just starts the update install and enters the bootloop.
I've done some research in to flashing a recovery image or manually applying the OTA update. One problem I've noticed is that I have absolutely NO idea what version of Android / CM my device was at before the update, and I have NO idea what version it was trying to update to. I do know that it was some version of Marshmallow before it broke. I've had no issues with the phone before this, aside the occasional self-reboot.
I REALLY want to keep all my data (pictures, contacts etc.) and am very nervous about actually doing anything because I have very little idea as to what I'm really doing.
Can anyone offer any advice on how to get my phone to boot/update/recover through Fastboot with a locked bootloader and without losing any data?
Thanks,
Stormin'
AKA the "HOW DO I PLAY BOOM BEACH NOW?!" guy
Edit: I solved my issue. It might work for you too, permalink to my post (#9) below: http://forum.xda-developers.com/showpost.php?p=67278091&postcount=9
Are you able to get into recovery mode? If so, you should be able to just flash a new ROM. Sideload one using the adb push command, wipe your data (this will clear settings, apps, etc. DO NOT SELECT SD CARD - that will wipe your personal files including your photos). Then install. Hopefully it should all work fine.
If you can't access the recovery can you access the bootloader sceen (the one with the big green bugdroid)? Then I'd suggest using Fastboot to install a new recovery. Then try the above.
If you can't even get to that stage you're screwed, just like me (unless anyone has any ideas). I've had soft bricks many times before but today I can't even get to the bootloader screen. ADB says the phone is offline. The screen is back and flickers on for a split second every now and then. Bloody CM Updater.
As IBM9001 has said, if you can get into recovery - even being stock - you can still clear your cache - don't do a full factory reset, just the cache, this may help, but even if it doesn't it still rules out one option.
I can't access recovery mode, using the key combo it just boots straight into the installer.
I've got a support ticket open with OnePlus and a scheduled remote assistance tomorrow. However from the preparational email it looks like they are going to factory reset the phone and then clean install CM. They've instructed me to make sure that all my files are backed up... I assume this means I will lose them.
Is there ANY way just to access or pull the photos off my phone? That's the most important bit. Dropbox hit its storage limit at the beginning of 2015 and I refused to pay, so now I have 18 months worth of pictures that I have no other copies of on death row
The only thing I can access is Fastboot...

I can boot into Fastboot mode, and plugging my phone into my PC works i.e. it is recognised. I have the fastboot .exe and USB drivers, and can issue commands to my phone through cmd such as
Code:
fastboot reboot-bootloader
which works.
How do I use a recovery .img through Fastboot? or can I pull the contents of the sd card through Fastboot?
Hey mate i had same problem with my friends phone. But in that case i was able to open recovery mode.. So if you can do that just download any full zip of opo.. Like cm12.1 or cm13. Then flash it without clearing data.. So will not loose amything not even a single application..
I did that by using adb sideload just google it how to use it. And for that download full android sdk toollit and then download only fastboot and adb domt download whole studio. Because somete old version of adb and minifastboot will not work on adb sideload... So good luck with that..
Hi guys,
I have the same issue!
If I flash a new recovery from fast boot will I lose my data on sdcard?

I'm currently having a very similar issue, but my phone completed the update. It's just stuck in a reboot/"optimizing apps" loop. I can boot into recovery and I tried to clear cache, but It's still just optimizing apps then rebooting and optimizing again over and over. Do you think your suggestion would help me too?
Wooooo, I've fixed it! I don't know why what I did fixed the issue (probably bypassed something) but my phone is up and running again! First thing I'm doing is making a freakin' backup!
So I was just trying everything in desperation. So that others can attempt to fix the same problem, here's what I did:
1. State of phone was either boots normally and crashes when installing update, or boots into fastboot. Would NOT boot into recovery!
2. Booted into fastboot using key combo (hold Volume Up, then Power Button)
3. Attached phone to computer via data usb lead
4. Started up cmd console, used command "fastboot devices" to check that device was recognised (note you need the fastboot files and USB drivers etc., Google it if you're not sure)
5. Used command "fastboot continue" to continue with 'autoboot'. This rebooted my phone but skipped the installer and went to the 'optimising apps' stage. Left phone alone for a couple of hours but it got stuck in another bootloop optimising apps, rebooting, optimising apps and so on.
6. Turned phone off, then booted normally with just the power button. This started the update install again except it didn't crash, and completed the update install. Then it optimised the apps again (albeit with a different total app count) and once finished, phone starts up normally.
Thanks for all the suggestions everyone! Happy to have my phone back. Now to go through the half-dozen or so voicemails I've collected over these last few days... great.
Hi guys,
@stormin, congrats!
@masterjigar, so you didn't lose the data like photos etc. doing so?
I can boot to recovery, but can't connect by PC to it.
In fast boot mode my PC sees it as well as in dab sideload mode.
I haven't the boot loader unlocked then I have to do it first, right?
But cyanogen site says that unlocking the boot loader will wipe all the device data.
Is there any way get the photos and other files back?
Thanks.
From the FAQ:
Q4a: Can I flash ROMs or SuperSU or anything else with the stock recovery?
No, the stock recovery can only flash zips that are signed by CM, this means official updates only. You need a custom recovery to flash anything else.​

Does it mean I can flash an official CM firmware without unlocking the boot loader?

That's what adb sideload is all about. It will give you temporary adb access (which is always after unlocking bootloader and root). So you can also flash xip via sideload. Without losing data and media..
Same problem, Also PC not detecting my phone
Hey Guys, I am Stuck at the same thing at Bootloop. But to do anything further I need to connect my phone to the PC. I haven't been able to connect my phone to PC since the time I have got the phone. I tried all available drivers and even tried different cables. I dont know what has been left out to try.
If any one has a working driver pls share the link. Its been three days now that my phone is dead.
Pls help!!
Thanks in advance.

You can't adb sideload .img or a partition.
You have to use fastboot.
Code:
fastboot flash boot boot_img_name.img
or
Code:
fastboot boot boot_img_name.img

I somehow broke TWRP

I haven't really touched this tablet in a while, but i wanted to start using it again. I was running BlissPop. It was slow, and kept giving me an error when it was trying to update, so I decided to try a different ROM. So I downloaded the lineageOS ROM and tried to flash it.
However, TWRP kept giving me an error when I tried to flash the ROM. I don't remember exactly what the error was.
So, I thought that I needed to update TWRP. I tried through the "Official TWRP" app, but after doing so I was unable to boot into recovery mode at all. I could still get to the bootloader, but when I tried to select recovery mode it would give me an error and dump me back out to the bootloader menu.
I tried installing twrp through "TWRP Manager" app, but it just says "something went wrong"
I tried doing this using ADB. I connected the tablet, enabled USB debugging. If i do the ">adb devices" command, I can see the tablet. Then I did >adb reboot bootloader - which works, it reboots the device into the bootloader. But then I try and flash recovery and nothing happens, it just says <waiting for device>. And if I do > fastboot devices it doesn't list any devices.
If I reboot to the bootloader and select "Recovery Mode' i just get the nvidia boot logo and it stays there forever.
I don't know what else to try at this point.
I think I could get this to work if I could just get fastboot to recognize my device, but I'm not sure what's preventing that from happening.

Did you set:
Allow oem unlock in dev opt.
Fastboot protocol into BL?
Twrp app & manager need root to work.
Just flash the latest stock ROM first, lineageos requires having latest firmware.
I wrote a little guide not long ago about that (obviously, you can skip the F2FS steps if you don't need F2FS and just flash ROM after flashing latest TWRP)

thanks for the help, i'll try and work through this soon.

I had seen your thread, and was intending on following it. nice post. 2 quick questions though
1) this is a shield tablet that was supposed to be remotely bricked by nvidia after the warranty claim. Will that happen if I flash the official recovery ROM?
2) how would I even flash that rom if I can't get recovery mode to work in trwp?
I think the root problem that I'm having is that I can't seem to connect to the device via fastboot (i'm sure i used the wrong terminology somehow)
edit: well I downloaded the USB driver for the shield tablet from nvidia, and i was able to install that (rather than the google usb driver). Fastboot finally recognized my device after that. I'm trying to flash the recovery now, but it doesn't seem to be doing anything, just been stuck on this screen for a while now: https://i.imgur.com/BUwj3Hx.png guess I'll continue to wait a while.
edit 2: well, finally got TWRP to flash over fastboot (https://i.imgur.com/tV1DqDv.png) however I still can't enter recovery mode. I just get the nvidia boot logo and then nothing happens. TWRP manager still says i don't have it installed either.
i'm about ready to give up on this... i've spent like 6 hours on this crap already and I feel like I keep getting further away from it.

Okay so I'm guessing you have stock ROM.
To flash TWRP you have to enter fastboot mode (vol down + power I believe) and flash the twrp image with fastboot flash recovery twrp.img (rename the shield tablet twrp to just twrp.img and place it into your easy adb and fastboot folder)
And DON'T reboot into OS, rather use your volume buttons to navigate to "restart to recovery" or just use hardware keys again directly from TWRP (vol up + power).
Good luck

Agreed. This is probably what is happening (as described on the TWRP webpage here:
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
Alternately, immediately rooting (flash SuperSU or Magisk) right after flashing TWRP, will prevent TWRP from being replaced with stock recovery.
Although the inconsistent fastboot connection, and how much trouble you had flashing TWRP initially, is a bit worrisome. Try using a different cable (maybe the one you are using is not connecting well?) try another USB port on the computer, and don't use a USB hub (connect direct to the PC).
Well, like they say: persistence is key. I kept pushing and trying new things until eventually.... I bricked the device. No, not really, it's working great now on LineageOS.
Thanks again to everyone who helped me out :good:. I'm still not sure exactly what caused TWRP to stop working on my device, however following this guide helped me fix it: https://forum.xda-developers.com/shield-tablet/help/help-stuck-nvidia-boot-screen-t3076462
The "flash-all.bat" restored everything to stock (including the recovery mode) and after that I was able to flash the latest TWRP and install Lineage.
