[Q] Can't flash recovery of Motorola Photon Q

Hi together,
I've got a Motorola Photon Q 4g LTE mobile phone and this afternoon I wanted to install CyanogemMod, but whatever I do, I stuck with the following problem:
I can't install any other Custom Recovery. I tried ClockworkMod and OpenRecovery, but I always get the s**t Motorola Bootloader, when I start in Recovery Mode. The Bootloader of my Phone is unlocked via Motorola Website, as told in many other threads.
I know that the users arrrghhh, shabbypenguin and Skrilax_CZ are great experts with firmware and such things, but I'm not allowed to write in developer's forums because I'm new here.
Has anybody got an idea for me, how to geht the Custom Recovery to work?
Btw: I tried to root the phone as well, but that wasn't posible. May be things come together or depend on each other.
Thanks for your help!

When you flash recovery (IE run the fastboot command) is it successful?
With the phone in fastboot/bootloader mode, type "fastboot devices" in the command prompt (where you run the fastboot flash command) and what does it output?
Also, try this.

When I flash recovery, I just flash the Motorola given Recovery by Motoroloa Bootloader. The Phone restarts, a logo with the Android Man is shown (stomach opend with some engeniering tools in it) and after about 5-7 Minuten, the system starts normally.
I also managed it to change the "Unlocked Message" into a Motorola Logo by using fastboot flash logo xxxx.bin and I nearly destroyed the flash by flashing an unlikely file. So the phone was shortly out of order because oder "flash failure" (fastboot mode). After that, I managed to flash the "boot.img" file of an CyanogenMod, so the flash was rebuilt and I could use the phone normally.

It shows the connected devices by showing a 8 or 9 ditigt number. It's almost the same view like I connected the phone without fastboot and use "adb devices".

This one I didn't tried yet, because I was so dissappointed of the mismatch with ClockworkMod & Open Recovery. Do you think, that trying this one will help, after two others failed?!
Thanks for you notice and your time. That's very helpful!

You need to boot to recovery after flashing it. There's a shell script that is re-flashing stock recovery - the dead Android dude with tools sticking out of him is stock recovery....

Ah ja, now I'm one step closer. I did not know, that the dead Android dude is the sign for stock recovery.
I'll give it this afternoon another try and will report. A bunch of thanks to you at this time!

Hi, it's me again. I managed now the reboot to recovery, by holding the volume up button while doing the "fastboot reboot"-command with the command box. That worked and I could start Photon Q Open Recovery 2.06.
Unfortunately, I did something wrong or so and now the script re-flashed stock recovery again. Nevertheless, I now know how to operate and will do the rest by my own (hopefully).
@arrrghhh: Thank you very much for your help!

So, I finally did everyhting the right way (now with ClockworkMod Recovery), because I now have CyanogenMod running on my Motorola Photon Q
:victory:
@arrrghhh: Thank you very very much!

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.

okay so i was able to unlock the bootloader and start flashing but from fastboot flash recovery.img and beyond it says failed to write. any ideas of why?

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

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.

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.

so ive followed the steps in the link, and ive executed all the commands but when i get to fasboot flash system system.img it says write failed. also all the commands beyond that one. ive got to be missing something. i have the image from nvidia developer, all the drivers, and my fastboot recognizes my device. has anyone encountered this before?

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.

Trying to flash TRWP Moto Z recovery - not working

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?

What if fastboot boot twrpname.img
It's really weird anyway...

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

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

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.

I found this other post on a similar device https://forum.xda-developers.com/general/general/guide-rca-voyager-rct6873w42-unlock-t3582973
Got into fastboot via usb debugging adb reboot fastboot (There doesn't appear to be a button shortcut to boot into it so you may be SOL even if a rom does come out)
Successfully Unlocked the bootloader
Was able to get a root shell via booting the cwm recovery
Dumped the boot.img, recovery.img via CWM but system failed
Was able to dump system via dd command
Still new to ROM building trying to understand vendor trees and device trees for building an AOSP ROM for it, noticed the system doesn't have a /device folder so a lot of tutorials don't seam too helpful.
Flashing the CWM recovery image from the above link breaks the recovery, had to flash back to old recovery, my next steps are to try and modify the stock recovery to enable adb so if i bork system i can button boot to recovery and use adb to get to fastboot otherwise it will be bricked...

I just got this device and was wondering how you got the bootloader unlocked. When I try to select OEM unlock in settings it just jumps back to off. And fastboot flashing unlock gives me an error.
Any help would be appreciated.

Hi yeah it's been a while since I bricked mine.. still sitting on a shelf as brick.. If I remember correctly when you do the OEM unlock from fastboot it flashes very briefly the screen to the unlock with instructions and button combination. What I did was run the command while using my phone to record the screen so see the instructions, then I went back watched the video to see what they were
I then went back to fastboot got the command ready again got my fingers in position before hitting enter and just tried to be as fast about it as possible and it worked for me.

How did you do a record the screen? Is there such an option while in fastboot?

Can you please tell me how you recorded the screen while in fastboot?
Thanks

I managed to get the bootloader unlocked on my Alco RCA Voyager III and just never got around to finding recovery or anything for it, this device a lost cause or am I just missing something? I don't think I can pull off making a recovery or rom yet but I can give it a shot if no one else is bothering with this device now a days.

@Trolldizzle How did you get it unlocked?
Thanks

@Isrgish I used fastboot flashing unlock command if I remember correctly, been a little bit since I did the unlock but I am like 90% sure that was the command.

i had get link here : findrom.info/rca-rct6973w43

Here you can find thr ROM. http://detonnot.com/3Xt3

Flashed the wrong boot.img

I ****ed up and flashed the wrong boot.img. I can't boot and I somehow lost my authorization for the PC so it won't let me issue the commands I need to flash the right boot.img, is it possible to fix?

It's a poor description to get a good helping attempt.
Anyway, generally speaking the way to fix this is using the official tool or a tool that works with your device and flash the official stock ROM.

Sorry, I'm not very good at this obviously. I am using platform-tools right now. I am getting "device unauthorized" when issuing adb reboot bootloader. I can boot to fastboot through recovery but when I try to flash the boot.img it just says < waiting for any device >. Earlier I fixed this by issuing "adb reboot-fastboot" and then flashing. But now I just get "$ADB_VENDOR_KEYS is not set" returned. That's why I'm wondering if theres any way to authorize the pc without a successful boot.

Not sure if you are mixing some things there, you are saying that you have "unauthorized device" through ADB commands but ADB works when device is on...but if you flashed a wrong boot image, could you boot to system some way?

You can't flash the boot image through recovery.

Because of a wrong (and also an unsigned image for your device) you have this message.
Which device you have? And have the bootloader unlocked?
