"Bricked" phone - Motorola One Zoom (aka Pro) Questions & Answers

Hello.
I requested help on wrong forum, first person that responded redirected me here.
Here's the copy-pasted contents of that post.
I have a Motorola. I typically leave my cellphone attached to my computer with USB so it can charge, slowly but surely.
When I wanted to get on my way I noticed my phone wouldn't start which I found interesting.
I left it on a charger for some time and when I held the power button to power up, I noticed it got stuck at boot.
What it typically does is open boot screen with Motorola logo, vibrate, start an animation and after mid-boot say "halo Moto" and then leave me at home screen.
But this time, it just get stuck on a boot screen. It shows the boot screen with Motorola logo, vibrates and then does nothing (until battery dies, I left it for an hour?)
I pressed the volume down and power button to enable debugging.
I get a "FastBoot AP Flash Mode" menu.
The options are:
Start (which puts me back into stuck boot)
Restart Bootloader (which restarts the FastBoot)
Recovery Mode (which gives me this: "No Command" with an Android icon, does nothing more]
Power Off (which powers off the phone)
Bootloader Logs (which changes some text to: "Fastboot Reason: Reboot mode set to FastBoot" or "Volume button down")
Switch Tools Mode (which toggles text between Tools Mode Config: DISABLED and ENABLED, no idea of other effects)
BARCODES (which probably shows scannable code so that professionals needn't type the ID)
I wanted to send it back to the seller, but they claim that they take no responsibility for loss of information, all my data is stuck on 128GB on the internal memory.
I would like to go to service for data recovery, but I due to COVID-19 everything's closed.
What could I potentially do to restore my phone? And if I can't, I can send it back, but how do I backup my data?
It's Motorola One Zoom.

I suggest we try the following solution to your problem.
First, check which boot slot the phone is in. It happens that in case of unsuccessful flashing the phone is loaded into a non-working slot.
Command to verify:
Code:
fastboot getvar current-slot
Make active Slot A:
Code:
fastboot --set-active=a
Then reboot the bootloader:
Code:
fastboot reboot bootloader
Perform user data wiping:
Code:
fastboot -w
And install the latest firmware for your model via fastboot.

I tried getting fastboot installed, but it got stuck at "waiting for any device" on the first command. After some painful entire hour of investigation I found out that I need USB debugging enabled, which I haven't done when the smartphone was working.
" It happens that in case of unsuccessful flashing the phone is loaded into a non-working slot."
I didn't update anything, nothing's changed about hardware and it had no access to Internet, so it couldn't update itself. Neither I nor any of my apps had the means to flash the phone.

USB debugging has nothing to do with fastboot.
If it's in fastboot mode, and fastboot commands are not working could be a driver issue.
How is is it listed in Device Manager?

The situation changed slightly since I came back from work.
Previously device appeared as unknown device.
With name "fastboot parker S", I have it in search history.
After rebooting (and installing 50 drivers) my device appears as "Motorola ADB Interface", however execution of commands don't end successfully.

About all those "remote" failures, the commands do appear in "Bootloader Logs", and the text is something like:
"cmd: getvar:slot-count" and "cmd: set_active:a". As someone with Android unrelated programming background I see nothing that would indicate an error on the phone.
Manually rebooting to fastboot doesn't change anything, rebooting the device in general doesn't solve the issue.
After rebooting I redid my steps:
Code:
X:\Applications\MinimalADBFB>fastboot getvar current-slot
current-slot: a

X:\Applications\MinimalADBFB>fastboot --set-active=a

Too many links? Corrupted file system?

Try to update the adb & fastboot drivers.
Phone is downloading into Recovery?
Ejects from the attached archive adb folder to the root of the C:\ drive.
I didn't have a problem with these drivers.

How? There doesn't seem to be official link to fastboot, every next website I visited has different edition. Half of links are dead, others have viruses. Even manufacturers of phones seem to have different drivers.

No, the phone is stuck at boot. It doesn't automatically fallback into Recovery, nothing changed since last time I entered "Recovery Mode".

How is a device determined by a computer in Device Manager?

Your phone is in the correct boot Slot A, where you should install the firmware.

Device Manager calls my phone "Motorola ADB Interface".
fastboot devices says:
Code:
C:\>fastboot devices
ZY226KZGT5 fastboot
"Your phone is in the correct boot Slot A, where you should install the firmware."
Is there a way to recover data first?
"Is the bootloader locked?"
I have no idea.
Screen mentions:
"oem_locked"
"AP Fastboot Flash Mode (Secure)"
Code:
C:\>fastboot flashing get_unlock_ability
(bootloader) use "oem get_unlock_data" and web portal
(bootloader) http://motorola.com/unlockbootloader

"Is there a way to recover data first?" - Are you sure there's something left? Then remove the line "fastboot erase userdata" from the .bat executive file and your data will be saved.

- After four subsequent link clicks to "[FIX] Phone Reboots Into Recovery Mode & Can Only Be Started From Fastboot", the post mentions "Your Cedric will boot normally again", but I have Motorola, other of your post say that you shouldn't downgrade flash, also the adb shell dd if=/dev/zero of= writes null to the given partition. No further instruction on how to get into "TWRP" boot. No way of knowing if it will preserve my data.
- Verizon Tool detects my cellphone but after half an hour its still not done initializing.
- Lenovo Assistance requires USB debugging.
- RSD Lite's instructions say: "WARNING Restoring your Motorola firmware will factory reset your device and you will loose all data on the device and have to set it back up like a new phone.", can I recover my data before hand?
No recovery instructions, tree of links and still no answer, can I restore the data?
It seems that people read only first 10 words and then copy link on "I've written tutorial on how to fix failed flashing" and they skip past "I want to backup my data" and "I haven't flashed my smartphone, it just happened".
Every next poster seems entirely oblivious of the main post and every post that comes before the post they respond to.
I get it, you're educated on the topic and have everything figured out, I don't. Why do you assume I would know how?

As I said in your other thread.
You cannot backup data with locked bootloader.
If you want to save the data, take it to a shop that has the special tools required.

Connect the phone to pc and type in "fastboot devices" - do you see any device listed?
Also the correct command is:
fastboot --set-active=a

Again, type it correctly.
In other words, spot the difference
fastboot --set-active=a (what I wrote)
fastboot --set active=a (what you wrote)
Do you see android/fastboot device in your device manager on the PC when you connect it to the PC in fastboot mode?
Edit: also replace fastboot.exe and adb.exe in c:\ADB\ folder as this one is being used. Or remove this folder from Windows PATHS.

fastboot --set-active=a (what I wrote)
fastboot --set active=a (what you wrote)
Do you see android/fastboot device in your device manager on the PC when you connect it to the PC in fastboot mode?
Edit: also replace fastboot.exe and adb.exe in c:\ADB\ folder as this one is being used. Or remove this folder from Windows PATHS.

Are you sure that phone is in fastboot and not in recovery? What do you see on the phone screen?
You are doing too many things at once, focus on one thing and once you get it solved, move to another one. Also please provide answers to all questions, they are essential for troubleshooting.
1. Reinstall drivers and ADB - https://forum.xda-developers.com/showthread.php?t=2588979
2. Reboot phone in fastboot, connect it to the PC and type in "fastboot devices" - do you see any device connected?
Phone is now Started so what i did was.

I guess you again did not follow given advice. You are still using old fastboot. In this case use "fastbot set_active a"

Oh God thanks it worked, Can you tell me why there is A and B ? i mean 2 slots? also how do i get the device into factory fresh ?
Like the 1st time when i bought this. thank you soo much + Liked
If i use Mi Flash tool again, So am gonna be in Danger again too?
You can use MiFlash, but before flashing you need to make sure that your active partition is A (with commands mentioned before).
To restore to 100% stock:
1. set partition A as active
2. run MiFlash WITHOUT locking bootloader (or run script flash_all.bat)
3. start the phone, if everything works, move to the next step (ONLY IF PHONE WORKS)
4. run MiFlash with bootloader lock (or run script flash_all_lock.bat) or run "fastboot flashing lock"
5. after reboot, your phone should start as if it came from a factory

Thanks Everything is now great. However what is slot count? and what happens when it hits 0? also i locked the device via fastboot flashing lock.
It should be number of slots. 2 = boot_a + boot_b
It it hits 0, I guess you have serious problem as bootloader doesn't see any boot partition.

Question Any custom ROMs out there for Moto g play 2021 (guamna)?

Can't find any custom ROMs for this device. I guess it is too early. I'll probably have to get another phone. Can't even find a twrp for it. New to this. Any suggestions?

You can root it and use Magisk to clean things up but no de-Googling. Check out the thread.
Any device that launched with Android 8 or newer is compatible with GSIs. Any device that launched with Android 10 or newer use super.img, which require the extra step of repacking rather than flashing directly. This is what I would recommend if you want ROM support on a brand new device.

You can use a Treble system Image! <See below for files>
To flash,
Step #1: Use the treble info app to see if your phone supports treble (Optional, I know the moto g play 2021 is compatible)
Step #2: Download any treble OS from here: https://github.com/phhusson/treble_experimentations/releases/ (Or use files below)
Step #3: Download 15-second adb installer (I Prefer this because its fast than searching for drivers) Download Here: https://androiddatahost.com/wp-content/uploads/15_Second_ADB_Installer_v1.3.0.zip
Step #3.5: I assume you enabled oem unlock and bootloader, but if not, instructions are below
Step #4: Unlock your bootloader
(Step #1: Enable OEM by going to about phone and tap build number 7 times (I'm sure you know the rest )
Step #2 Hold Vol down, (While holding Vol down) connect to PC.
Step #3: Go to https://accounts.motorola.com/ssoau...ct/standalone/bootloader/unlock-your-device-b
Sign into google or moto id, and follow steps to get unlock code (For bootloader unlock))
WARNING!! DATA ON DEVICE IS GONE!! WARANTY NOW VOID!!
Step #5: Run the command in CMD (as admin): adb devices (Starts ADB service)
Then run: fastboot devices (Your device should be connected)
Then run: fastboot oem unlock <unlock code here> (From website provided)
Then: You should get a message saying: Warning Blah Blah Blah. Just read the message
DONE! (Should reboot to factory settings)
Step #6: Turn device off, then hold Vol down, and connect to PC
Step #1: Make sure to have put the <imagename>.img you downloaded earlier in the adb folder in your windows local disk (and renamed it to "system.img" to make flashing easier)
Step #7: Reboot to fastbootd by running: "fastboot reboot fastboot" in CMD
Then run: fastboot erase system
Then: fastboot flash system system.img (Might get error message!) (To fix, run "fastboot delete-logical-partition product_a" Then run "fastboot flash system system.img" again)
Then wait. . .
After, run "fastboot -w"
Then: "fastboot reboot"
DONE!!!!!! Enjoy

Now, if I were to download a rom from the site, would it be A only? B? A/B?
They are all A/B, just check the filenames. If you read the release notes, they state there is no A-only build yet.

Make sure you have the current version of fastboot, AND that it's the one that you're using. Ran into that problem mysself, updated my PATH incorrectly and had it pointing to the wrong fastboot.exe.

Moto E7 Stuck In Fastboot And Won't Let Me Flash

So my buddy has a Moto E7 that randomly started crashing and then got stuck in Fastboot mode. I tried LMSA and it won't detect the phone. I have tried manually flashing, RSDlite, followed a video to turn the XML file into a bat file, and it won't let me flash anything. I've spent hours googling different methods and even looking on these forums at other devices and following those steps and have had no luck. The phone is oem locked, when I use the command fastboot getvar all almost every field is blank. The ones that aren't are just the information about the components inside and serial number. Values like imei are blank, but I have the number. When I try a command like fastboot flash logo logo.bin I get:
Sending 'logo_a' (1292 KB) OKAY [ 0.034s]
Writing 'logo_a' (bootloader) Failed to erase partition
as a response. This is the same response I get for every situation of trying to flash something and when I try to erase I get met with:
\fastboot erase userdata
Erasing 'userdata' (bootloader) Failed to erase partition
FAILED (remote: '')
fastboot: error: Command failed
What am I missing? I just get a failed response from everything. I'm guessing the internal storage isn't formatted but I can't find a solution to format it from this state, and like most things I've search it gives me what to do when I can access the phone but not what to do when the phone is stuck here.
if the bootloader is not unlocked you can't flash a rom via fastboot...

Hi, Have you already tried flashing using SP FlashTool?
Check the version of FlashTool and the ROM that LMSA downloads are correct.
In theory you should be able to flash the ROM without unlocking the bootleader. ^^'
FlashTool must be set to "Download Only" or "Firmware-Update"
"Format and flash", or something similar, delete the IMEI, which I would not want.

TCL 20b Subforum

Hello there,
A newbie here, trying to unlock a TCL 20B (6159K) phone.
Android 11, November 2021 security patch (MTK Easy Su doesn't work with that, reportedly some vulnerability was patched), fastboot accessible but acting weird.
1. Got fastboot from here.
For some reason it doesn't understand the -i option, but connects with the only phone I'm trying to unlock attached anyway.
VID is 0x0e8d, btw.
2. Got adb from don't remember where about a year ago (for my previous Lenovo phone)
3. Unlocked the Developer Options
4. Checked "Allow bootloader unlock" and "Enable USB debugging" options there (not sure how those are named exactly in English, but I 100% guarantee, I've checked the right ones)
5. Sent phone into fastboot with
Code:
adb boot bootloader
6. Checked the unlockability with
Bash:
fastboot flashing get_unlock_ability
(bootloader) unlock_ability = 16777216
OKAY [ 0.005s]
Finished. Total time: 0.006s
7. Tried to unlock the thing, but
Code:
fastboot flashing unlock
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
and
Code:
fastboot flashing unlock_critical
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
8. Searching here, on XDA forums revealed there's no TCL 20B sub-form.
9. While there are tons of topics on not allowed in locked state, none of those helps.
fastboot oem unlock is seemingly an old way to do things (TCL 20B is a rather new device released WAY past 2015)
TCL is an Alcatel device, not a Xiaomi or some ZUK one, to require an account (haven't found anthing on "alcatel account")
trying to load some recovery from PC that might work failed as well (for the same reason)
Code:
[/LIST]
./fastboot boot twrp-3.6.1.img
Sending 'boot.img' (8932 KB) OKAY [ 0.212s]
Booting FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
I've read some TCL 10 phones don't even have a fastboot, but TCL 20B clearly does.
Any Ideas how to unlock the bootloader?
P.S. Maybe a new sub forum for 20B? This got placed into the "TCL 20 5G" one, which doesn't seem right.
EDIT:
Ok, have found how to proceed on my own.
Even rooted the thing.
Go here https://github.com/bkerler/mtkclient, grab the ISO, backup, install patched magisk, patch the boot_a, flash patched boot_a and empty vbmeta_a, erase metadata, userdata and md_udc. Reboot, reinstall pathched magisk.
Don't lock the bootloader to avoid red state.
Huge kudos to mtkclient devs
Hello, i been trying to root my tcl 20b (6159a) but i cant figure how, i follow the instructions of mtkclient. Install it in windows, python, mtk repository, all the process, but when i try to replace boot_a.img it doesnt work from the cmd command, but in the python mtk_gui i can replace boot_a.bin and erase vbmeta_a.bin when i do it from there the cellphone keep in bootloop, i can fix the bootloop but cant root it. If u read this, can you plz be more specific with the steps, and made a little tutorial, its not necessary images or video just some more in deep info how you achieve root, thx
