Trying to flash TRWP Moto Z recovery - not working - Moto Z Guides, News, & Discussion

Hey everyone, longtime lurker here finally going to try to get involved more since I just got a new Moto Z and I don't have much of a background with motorola hardware/software. I'm trying to flash recoveries through fastboot and I can't seem to get it working. I'm probably going to wait a while before I try again since there is not much support for the moto z yet. I am running MPL24.246-45 v6.0.1 XT1650-03, I have unlocked the bootloader through the instructions on the motorola website.
On the bootloader screen I can confirm it is now unlocked, but everytime I flash the TRWP recovery through fastboot I get the error message: "<bootloader> img not working or corrupt". I am trying to flash the most recent twrp recoveries for moto Z (twrp-3.0.2-0-griffin.img) but wasn't able to successfully flash it.
Coming from a samsung background, I might be skipping a step or doing something wrong. I am running the bell canadian firmware. Since I messed up my partitions on my last phone I want to be careful with this one, I mostly want to figure out why I am getting this error while trying to flash the recovery when
my bootloader is unlocked and when I check "adb devices" my moto is being read.
Thanks!!

didn't try it yet, but did you try renaming it to recovery.img (if on windows be sure extenstions are shown so it is not actually recovery.img.img) and run (didn't see which command you are using:
Code:
fastboot flash recovery recovery.img
but search around forums about encryption thing and similar

I've tried both with the original twrp name and extension as well as with renaming it to recovery.img, didn't seem to make a difference. If I am connection to the device itself does that mean that adb/sideload is installed properly? I mean I was able to unlocked the bootloader so I would assume so.

i really don't know then.. if you successfully unlocked bootloader then fastboot should be ok. you can check in device manager. it should be bootloader iterface not adb interface there (you got me confused with mentioning adb so I am just writing to be sure).
also check if your device is shown when typing
Code:
fastboot devices
or try redownloading twrp.
otherwise I am out of ideas, sorry.

Sorry for my confusion with adb/sideload - from what I understand I need both to be able to connect to my device (correct me if im wrong). In the bootloader menu I see "flashing_unlocked" which I believe confirms my bootloader being unlocked, but then at the top of the text right under the dead android guy I see "AP Fastboot Flash Mode (Secure)" could that be an issue?
I can retry downloading the recovery from the TWRP site, but I know I'm downloading the official one already, just can't put my finger on why I'm getting that error message if others are doing it successfully.
thanks for helping :good:

You're at the bootloader, it says Flashing Unlock so yes your bootloader is unlocked and you should be able to flash TWRP no problem.
Did you recently install this .45 firmware? Are you sure that TWRP wasnt actually flashed? I see lots of errors like this from the bootloader and its usually just rubbish.

The twrp does not show the actual memory value of my cell phone and does not let me paste ROM backup, from insufficient memory? how to support it?

I updated my phone to .45 when I bought the phone I believe 1-2 weeks ago, it's definitely NOT flashed as the flashing process runs for 0.2 seconds and fails. I can even boot in the stock recovery afterwards confirming that nothing flashed. I wish I knew what I was doing wrong? possibility of drivers not installed properly?
Before I try and flash recovery I check USB debugging, OEM is unlocked, don't verify ADB files and accept Unknown sources. Is there anything I'm missing?

I've been doing fastboot flash twrpname.img after opening cmd terminal with SHIFT-MOUSE2 in the designated folder. I have not tried that command specifically what's the difference between doing fastboot flash/boot as far as flashing a recovery.img
edit: I've read on different articles that people sometimes try and flash from the recovery menu? I understood it has to be while your are on the bootloader screen, could it be something to do with that? Or is it still a possibility the drivers may not be installed properly.

With fastboot boot you send recovery to your phone and ask it to boot on it without really flashing it...
It's useful e.g. to take a full stock backup including original recovery, to test a recovery prior to flash it or to use TWRP to root BUT remain on stock recovery...
Not on all phones it works, but on Moto Z should....
P.S.: you have to be on fastboot screen not on recovery when flashing...

by fastboot screen you mean the bootloader menu right?
I've been accessing cmd from designated folder with .img file in it
- adb fastboot recovery
- fastboot flash recovery.img..
and I get the "img not working or corrupt" after it tries to flash it (lasts 0.2 seconds) and nothing is done.

Right, bootloader screen. Enter on it by key-comb... not by command...
Even the real flash take same time... Sending seems to work, is something on verify that doesn't "like" it...
Try to download again recovery and/or check its MD5...

if reading correctly (and what I told you yesterday) command is
fastboot flash recovery recovery.img
and not
fastboot flash recovery.img

try following this instructions: http://forum.xda-developers.com/showpost.php?p=69065373&postcount=14
and download eu rom from here: https://mirrors.lolinet.com/firmware/moto/griffin/official/RETEU/
i don't know from which ROM you are coming, don't know if downgrading works, but this was onl RETEU ROM i could find.

I have the exact same phone and I've upgraded to Nougat but I got my TWRP working. You need an unlocked bootloader and after upgrading to nougat, the option "unlock OEM" need to be enabled again.
I've used this TWRP : https://dl.twrp.me/griffin/twrp-3.0.2-0-griffin.img.html
Also I tried to only boot on it at first with the command fastboot boot twrp.img then I saw it was working, I flashed it with fastboot flash recovery twrp.img but got the error : (bootloader) image not signed or corrupt . But I booted the recovery from the bootloader and TWRP was working even with this error.

Yeessss... I don't know how could I forgot it!!! :silly:
The message (I forgot I received too...) is *only* to indicate that recovery is not signed! But before there is a clear "Done" confirming the flash!
Just boot on it!

Recovery failing to flash

So I flash the stock rom on it without thinking and now it wont let me flash a recovery to the tablet threw fastboot or goomanager and it wont update throguh asus update but its booting fine and wont take any updates at all i need help being pointed in the right direction!
I flashed the wrong bootloader i think and how do i flash the correct bootloader without a recover?
in fastboot im getting the error: cannot load 'file name' :no error weather its cm or twrp it wont load it and i dont know what to do please help
First of all it would be important to know what bootloader you are actually on. You do not want to flash a recovery that is not compatible with your bootloader!
So boot into the bootloader with Volume Down and POWER and read the tiny script. From there select the Android with Volume Down and boot back to system with Volume Up.
And then please report in detail what you are trying to do in fastboot, which commands you use etc.
Without knowing what you are doing we cannot tell you what you are doing wrong.....
First step: In fastboot command: fastboot devices - Do you see the serial number of your tab?

So you are on an ICS bootloader with a JB rom... How the hell did you manage to do that?
You did not answer my question about fastboot. What you tried and what did not work.
But anyway, how I would proceed, just to get you back into safe territory, is to download the latest Asus firmware 10.6.1.14.10, unzip the downloaded file once and copy the resulting zip to the root of your internal SD.
Reboot, and hopefully the stock recovery will recognize the update file and flash you to JB 4.2.1 (which BTW is the latest version for our tabs - there never was, and probably never will be a 4.2.2). Flashing the stock firmware will replace the bootloader.
So from there you just have to get fastboot working, flash the latest TWRP and then the custom rom of your choice COMPATIBLE with your bootloader and recovery.
If that doesn't work we have to try something else. But try this first and report.

TF300T 4.2 TWRP Error

Hi XDA,
I am a complete noob, and this is my first time posting, so bear with me.
Some time ago I rooted and unlocked my TF300 with SuperSu. Recently I wanted to upgrade to 4.4 kitkat. However, my Tablet was stuck at Andriod 4.1 because of the the unlock.
I went to manually update my TF via the Asus website. I installed the 10.6.1.8 using my TWRP 2.5, and Oem 4.1 OS. Installation worked just fine. After install, I booted up and I had 4.2 with everything working correctly.
Next step was to install TWRP 2.7.0.1. I reset my TF and went into RCK to see something went wrong when updating.
My TWRP will not load, and I get the Android on his back with the red triangle when I try to enter RCK.
Thanks in advance!!
I managed to install 10.6.1.27, but it did not change anything with my boot loader.
I downloaded motochopper, but that didn't seem to work, just told me my abt was out of date. SuperSu isn't working now either, "No Binary, There is a problem."
How do I install TWRP 2.7 with no boot loader? Please help.

Most people just install TWRP via fastboot like
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
You could try using other root methods, like Framaroot or Kingo. I think Kingo was reported to work on the latest stock version.

I will look into that, but I am pretty sure I was already rooted, unless losing my boot loader means I am no longer rooted.
Another thing, I can't find a twrp.blob for 2.7, just a zip. I have one for 2.5, but that is useless because I already have 4.2. I also have not been able to find a working link to fastboot.
If anyone could give me a link to the fastboot or a link to a tutorial, that would be amazing. I have done my research, but all the lingo and different methods can be mind bending.
Thanks

You can get the img (which substitutes as a blob) from extracting it from the TWRP 2.7 zip file.
1) You will need ADB and fastboot for this: http://forum.xda-developers.com/showthread.php?p=42407269. I would suggest keeping the tablet at least at 50% battery.
2) Install Naked Drivers. This may be optional for you. If you can proceed to the next step without, you won't need it.
3) Enter fastboot by rebooting and holding down the power button. TF300 enters fastboot automatically since this is 4.2 BL.
4) Next we need to enter a command. In side the ADB folder, hold shift and right click. Then select Open command window here.
first check to make sure the device is connected:
Code:
fastboot devices
The device serial number should be listed.
enter command:
Code:
fastboot flash recovery twrp.img -i 0x0b05
Blue bar on device will fill. Be patient.
5) Reboot the Device back into Android. This is an important step.
6.) Go back into TWRP and install what you want.
You are amazing. I will give it a try tonight and report back!

Installed adb fastboot. However, my device does not automatically go into fastboot, I still have to hold down the volume key.
Once I am in fastboot usb (with the 3 icons), I fastboot successfully and get the serial number, then when I type the 'fastboot flash recovery twrp.img -i 0x0b05' command I get this error: cannot load 'twrp.img' : No error
I am attemping to use the 2.7.0.1 twrp from the 4.4.2 page. I have extracted the recovery.img (tried renaming to twrp and left it the same) and placed it in the root of both my external and internal sd.
I have now tried it with .zips .img .blob and I receive the same error everytime. Not sure what I am doing wrong now.

Awesome! Worked like a charm. twrp 2.7.0.1 installed perfectly.
Then I tried to flash the cyanogenmod. Said it installed fine, but it just gets stuck on the loading screen...
I am trying to do exactly what TallMilk is doing...put Cyanogenmod on my tablet. It is my understanding that I have to unlock my bootloader though? Which I have tried doing a million different ways with the Asus Unlock tool which always gives me an error.
If I follow the instructions posted above I will be able to flash Cyanogenmod without unlocking my bootloader?

Finally got it to work. I had to do a wipe first, read about old roms interfering with new installations.
SilentSpartan, I used SuperSU last year to root and unlock my tablet when it was still a 4.0 android to flash to 4.1. This recent update was from 2.5 TWRP on a rooted device running 4.2. When I installed 4.2, it blew away my TWRP, and I had to flash the new TWRP 2.7.0.1.
That flash from OEM fastboot to TWRP 2.7.0.1 is what I needed help with.

You're going to have to unlock no matter what. Did you try both v7 and v8 of the unlocker and calling Asus Support to tell them to put your serial number back into the database (get a manager)?

Soft bricked shield tablet PLEASE HELP!

So I bought my shield tablet back in March, used it until about may I think. Was browsing the internet then it suddenly crashed and got stuck on the Nvidia boot screen. tried to reboot several times. Nothing. So I forgot about it and thought I would just google the reset option later when I had time. Now since June I have tried everything! From factory reset to fast boot and adb my pc won't even recognize my tablet. Also I never turned on usb dbugging cause I didn't even know what that was. I even gave it to the IT guys at work and they couldn't fix it. Now after reading everything there is to read on this problem and trying to fix it myself I'm stuck on the no command screen with the dead android robot. And now I hear there is a recall do to the battery, I can't even check what type I have. So if someone can please help me I would be much appreciative. Also this happened after updating to the latest OS.

Hello,
Did you use "Fastboot flash recovery.img" as your command line??
I believe it is "Fastboot flash recovery recovery.img"
If you were able to unlock bootloader you're on the right track.

Yes I used "fastboot flash recovery recovery.img" but every command after that keeps telling me "failed to write file"

TWRP (Team Win Recovery Project) is a custom recovery that you can flash on your device. You can flash it like the stock recovery over fastboot. With TWRP you can make full system backups, installing roms or other stuff, wipe partitions and more. Keep trying to install the drivers on your pc. Try to use another usb slot or boot your pc into test mode to install the driver. If you can still access the bootloader, you have really good chances to rescue your device.
Okay will try that. Thanks man.

I see what your doing wrong. You probably don't even have the recovery img to flash. That's why it's giving you a write error.
There is a tutorial in the general section, that should have all the files and links, etc etc that you'll need to flash TWRP/CWM recovery and root the device if you want

If your referring to the recovery images from Nvidia website I have dowloaded that, also the correct drivers. Maybe there is something else I'm missing?

First off, let me ask, what is your end result for the tablet?? Are you trying to just go a Complete stock tablet or are you trying to do anything custom (ex. Custom rom, recovery etc etc)
I'm assuming that since you unlocked your Bootloader, your trying to do something custom.

Those official nVidia recovery images come with smaller .img files such as recovery.img, system.img, etc. You'll need to flash those one by one ("fastboot flash recovery recovery.img", then run "fastboot flash system system.img", etc. etc.) or you can just run the flashall script that I think is included in the nVidia images.
Otherwise, if you want to flash TWRP, you'll need to download the TWRP recovery (you can rename it to "twrp-recovery.zip"). Then you'll need to "fastboot flash twrp-recovery.zip" in order to flash the twrp recovery to your tablet.

I want my tablet to boot again, it's completely unusable in its condition I've heard re flashing will fix it.

OK. Then the link I gave earlier should help flash stock software onto your tablet.
However, that guide is only to go back to factory "state" Operating System wise. It may not help with hardware. Once your flash everything correctly but device still doesn't boot, its probably not software related.

After you unlocked the device but before trying to flash anything else on the device, try putting the shield into Fastboot mode. At the bootloader, select fastboot using the volume buttons.

So i selected "fastboot protocol" it blipped for a second then brought me back to the bootloader. tried flashing again and once i reached the fastboot flash system system.img it said write failed again. did it not engage the "fastboot protocol"?
Bringing you back to the bootloader was expected behavior. The "write fail" is a mystery to me. Sorry, that is all that I can offer.

How to Downgrade bootloader 41.1A to 41.18 or 41.19

please..
i have problem with bootloader version 41.1A
i want to Downgrade to version 41.18 or 41.19
anyone know ..??
please share it
thank you
Up
Me too
My bootloader v 41.1A I downgrade 41.18 Help
Why do you need to downgrade? Messing with Bootloaders can destroy your phone.
even i want to downgrade... I cant flash custom recovery on 41.1A

Bootloader cannot be downgraded. You're stuck on w/e version you have currently installed.
Okay so I'm stuck on 41.1A and my phone will continue to restart itself and then stuck in bootloop till the battery dies... and then when I connect it to the charger boot's up normally...
@lost101
Can you please let me know how to check bootloader version?
I am using Moto G XT1033 model(Asia).
It was updated to Lollipop 5.0.2 by Motorola Stock Lollipop update.
Later on I had unlocked bootloader and downgraded it to Kitkat 4.4.4 using this thread.
I don't have any clue about current version of bootloader in my Moto G.
I want to try Lollipop 5.1 Optimized stock rom link here, so just wanted to ensure compatibility of bootloader so that my phone works after flashing it.

Enter bootloader (hold volume-down while turning it on), read text on screen (second line).
I too want to know if there is a way to downgrade or at least reflash my damaged bootloader which is causing weird behaviour.

I have the exact same problem.
Stuck on 41.1A
Was on a slim6 rom before. Tried to return to STOCK_ASIA_RETAIL. All fastboot commands successfully executed but no apparent change. I have the exact same wallpaper, the same layers RRO navbars, everything. I would not need to go to STOCK but since the slim installation is unstable and everything force closes, the phone is unusable.
Additional note: Somehow even TWRP is stuck in the splash screen, so cant flash any other ROM. Even tried to access TWRP using adb, but the TWRP service fails to start.
I fastboot flashed phillz recovery, stock recovery & newer TWRP versions, but nothing happens. Phone still stuck in TWRP screen.
To my surprise I was able to pull my personal files from the internal SD using ADB (which still works btw).
But I'm left with a phone in a zombie unusable condition, it just doesn't react to anything.
Any help from the XDA community would be greatly appreciated. I am still keeping my fingers crossed, so that one day a guide comes up to brick my device (STOCK 5.1 bootloader) and unbrick it using some sort of unbrick tool.
Why is not possible to create a flashable zip with the bootloader inside? I want to downgrade to KitKat bootloader too

Creating such a zip is possible, but flashing it may either not work or hard brick your phone.
How to install working recovery on 41.1A bootloader
I had the situation on my Moto G XT1039 where I had formatted the partitions on my phone (using my old CWM recovery), then flashed the 41.1A bootloader, but 41.1A would not allow me to flash any recovery.
So I had a working bootloader, but no recovery and no OS. And apparently no way to install a recovery, to install an OS...
I got the phone back like this:
- Flashed 4.4.4 stock manually using the bootloader (if you do this, DO NOT flash the 4.4.4 motoboot.img, according to everything on here that will permanently brick your phone; I am not sure about partition gpt.bin - I flashed this, but I was already on the 4.4.4 partition layout anyway). Do flash boot.img, that is the OS boot.
- So now I had a bootable phone OS (back on 4.4.4 again, with a flickering screen), but still no recovery.
- From the bootloader, I booted into an old recovery which I knew had previously worked with my phone:
Code:
fastboot boot clockworkmodrecovery.6051.peregrine.img
(this boots into a temporary copy of the recovery, without actually installing it on the recovery partition).
- Using that, I installed the SuperSU binary.
- Then I booted back into my 4.4.4 OS, installed the SuperSU app, checked it was working, then installed the TWRP Manager app (which requires root, hence the previous steps), then used that to successfully install the TWRP recovery on my phone.
From there I now had the correct recovery in place to flash the 5.1 Optimized distro (which I would definitely recommend - clean, stable, excellent battery life!).
Yay!

Why didn't you simply fastboot flash a TWRP image?

I hope I haven't misunderstood, but isn't the whole point of this thread that the 41.1A bootloader won't let some poeple (including me) successfully flash anything to the recovery partition? You can run the command, but the recovery won't boot up. At least that's how it was for me.

I see. So "fastboot boot" worked, but "fastboot flash" wouldn't write anything? In that case you could probably also have used fastboot boot with TWRP and then use TWRP's "install image" feature to flash it.

Thanks! I definitely tried that first! Maybe this bit I didn't make clear in my post, but actually:
- fastboot boot was only working for me with older recovery ROMS, i.e. the older CWM recovery which I mentioned, which I had lying around from when I first rooted my phone on 4.4.4, and also - not that it's much use - with the recovery in the 4.4.4 image, which just brings up the dead Android logo
- fastboot flash recovery was not working at all, not even with the recovery roms which would boot with fastboot boot
- but fastboot flash to all the other partitions seemed to work fine (I could see that it seemed to be working because I was able to flash different logo.bin files to change the phone logo which shows before the phone tries to boot into recovery or OS) and as per my post this was how I was able to get my phone back eventually
This thread was the only place I could find which seems to represent people having the same set of problems, so I thought the above workaround might be useful in future to someone in the same situation.

So far nobody has posted a terminal transcript of "not working". Did it appear to succeed or did you get an error message?

That doesn't make any sense. Not that I don't believe you, I just can't explain how fastboot could fail writing recovery but succeed in writing a different partition.

It appears to succeed, except that it gives the 'mismatched partition size error' on the bootloader screen at the end of flashing. (Although other posts seem to state that this is normal for a non-strock recovery?)

Yes, I've got that one too, but my flashed recovery then worked fine. However I upgraded my bootloader by installing the complete 5.1 stock ROM, maybe your bootloader update was somehow incomplete.

(HELP ME ) Bricked

So i did a stupid thing and flashed the wrong image when i was installing a new rom, I managed to lock myself out of ADB, TWRP and download mode. I'm in a bit of a pickle right now I've been trying everything I can to fix it, but I managed to do nothing. Is there anyone that can walk me through the steeps to get unbricked.
I've tried recovery through hisuite, but it says my device is not supported. My phone showed up via CMD command (fastboot devices) but not (adb devices). I have no idea what to do?
PLEASE HELP ME!!!

Give the all required information like Brand, model number in your post first.
Huawei honor 5x kiwi L24, I can't really acces the phone so finding some information is impossible. My main issue is when I boot it's failing to verify the Boot.img , recovery.img and system.img . I don't exactly know what all information I can give you

I have already done that, I've tried flashing it via SP flash tool but nothing, it won't show up. I've downloaded correct drivers and done what I could but my phone shows up as Lemobile android adb interface. It sometimes shows as a disk drive as well.
When I run CMD command (fastboot flash oem info) it shows everything but the recovery.img system.img and boot.img need verification how can I verify them without the debugging bridge active on the phone.

Imgs are already verified cause they are official
And you don't need USB debug in fastboot mode
Your device is not has mtk processor so it won't work

I rooted my phone and was running xenon HD on my Huawei honor 5x, in the midst of switching ROMs I accidently targeted a TWRP recovery.img with the ROM and Gapps.
So what my phone dose now is when it powers on it an all green screen with a red box and a blue box. After a second it come up with " recovery image verify failed, please update to verified images." I can enter fastboot&rescue mode and a Huawei erecovery, but when i do try to download the recovery via WIFI it says package failure.

I had unlocked my bootloader but some research I was doing says, when you accidently flash wrong images it can relock the bootloader. I lost the original bootloader code and i don't exactly have the box anymore, so getting a new code will be difficult.

I have already sent an email to Huawei support, just waiting on a response to see if they can give me another unlock code. If I'm unable to unlock the boot loader again with the codes, what's my options for unlocling the boot loader without Huawei's help.
