AP Flashboot Flash Mode ( Secure)
No bootable A/B slot
Failed to boot Linux, falling back to fastboot
Fastboot Reason: Fall-through from normal boot mode
Hi everyone,
I've wanted to root my Android phone for a while now, so I decided to do it these holidays, following instructions on getdroidtips ( How to Install Lineage OS 17.1 for Moto G8 Plus | Android 10 [GSI treble] (getdroidtips.com) ). I couldn't boot into TWRP recovery mode for some reason, (maybe it didn't install properly) so I tried to install Havoc OS using ADB. My phone then rebooted several times and then gave an error message, saying I could either try rebooting again or factory reset. I chose factory reset and went through the whole process again twice, the third time with Lineage OS. It then gave a different error message (in the code block). I can use the volume keys like in the bootloader, but couldn't get it to boot. I also can't access the phone over ADB.
This was my first time messing with Android beyond basic ADB commands, so I didn't really know what I was doing. I might have messed up the instructions or made some other mistake. All of my data is backed up, so all I'm hoping for is to either boot Lineage OS or somehow flash the stock ROM again.
Does anyone know how to solve this issue?
BTW I am not on Verizon.
I've run into a few of these situations. I also tried this version of Android as a Custom Rom and got a Boot Loop
I had to use TWRP to reinstall my TWRP backup.
Just in case you don't have TWRP or TWRP access for some strange reason you could try this:
I have a moto g8 plus xt2019-2
Motorola_Moto_G8_Plus_XT2019-2_DOHA_RETBR_9.0_PPI29.65-43_(MobileGuru4.com)
Motorola Flash File For All Model (Stock ROM) - Mobile Guru4
Download Motorola Flash File for all Motorola models. Here all Stock ROM and firmware files given for Motorola phones are official original files
www.mobileguru4.com
Search for this on google, when you find it download it. Then inside the zip file once you unzip it find the directory that is labeled - firmware
Inside that directory there's a file labeled "flashfile.bat" This setup uses ADB with ADB Fastboot on the phone. I assume you know how to get ADB Fastboot on your phone. When you execute the above file you will see it working in the command prompt on your computer. Let it run. It will not show anything on your phone until your phone reboots. This is what I use as a DISASTER BACKUP in case TWRP is unusable or in any way I'm unable to get to it.
I hope this helps you, it worked on my phone.
Thanks for the reply. Unfortunately, I can't try it because I've already sent the phone away to be repaired. The repair company said they would have to send it away when I originally emailed them. The repair company had a no fix no fee arrangement, so if they can't do it I'll try using fastboot. Hopefully that will happen and I won't have to pay $200.
sorry my english, i have the same problem and already try everything, rsa always fails and rsd lite does not recognize my device in windows 10, i tried to short the motherboard and it didn't work, i am seriously thinking about changing the motherboard or sell the parts

Hey folks,
I'm rather embarrassed that I have to ask for help here, but here we go:
I wanted to update my Moto G (1st gen) to Lollipop 5.1 (via this thread: http://forum.xda-developers.com/moto-g/development/rom-stock-motorola-lollipop-rom-t3017510) and after toying around with it for a few hours got frustrated and did some stupid things, which I'm also having a hard time to remember.
From what I recall, I managed to flash the "GPE 5.1 ROM (Optimized) v1.1" ROM via TWRP, but when booting the phone got stuck on the BOOTLOADER screen for about 1 1/2 hours, after which I decided to turn off the phone.
After that I frustratedly started fiddling around in TWRP and wiped system, cache and some more things (derp :silly: ) and well... ever since then I'm trying to get a new ROM on my SD card, but I can't push via adp because my device is not found.
Here's the facts
- When I try to regularly boot up my phone, the Warning Bootloader unlocked sign appears
- I can access the fastboot screen on my phone (AP Fastboot Flash Mode (S) 41.11), the one where it says normal powerup, recovery, factory, barcodes, bp tools and qcom. When I connect via USB it says USB connected.
- I can get access the recovery rom TWRP (v2.8.5.0)
- When I try to push a ROM to my sdcard command line tells me "error: device not found".
aaand that's it. I really hope I didn't brick my phone.
I'm on Windows 7 x64 and I would really appreciate the communities help. After that I'll show myself out and leave my phone working for a while hopefully.
edit: one more thing. my phone gets recognized as "Fastboot falcon S" in windows when I plug it in while in fastboot flash mode and as XT1032 when TWRP is booted. obviously it doesn't get recognized as a volume in Windows Explorer, or I would have already transfered another rom on the SD card by now.
edit 2: I also tried connecting the phone via another windows 7 x64 laptop now. installed motorola device manager & minimal adb and fastboot, but same thing there. :|
edit 3:ISSUE RESOLVED for now. I used this: http://forum.xda-developers.com/moto-g/general/gpe-lollipop-5-1-1click-installer-t3075522 and it worked like a charm. Thanks everyone.
@covecove until there is fastboot, there is hope.
Hi there,
Today i've received this tablet. All good and dandy until it notified me it has an update so obviously i've gone and do the update. Surprise.. after reboot, update installment and so on the device won't boot anymore at all, and recover mode doesn't work to enter.
I've found official ROM package on their site:
ftp.vonino.org/public/Firmware/Vonino_Tablets/Pluri%20Q8/Orange%20Version/Android%206.0/
Tablet can connect to the PC, but it isn't recognized because "some drivers" missing. How can i install this ROM on the tablet from my pc ?
Thank you.
Hi,
I can't find anything about it on xda or anywhere. You'll need to contact the manufacturer for drivers and instructions on flashing their firmware.
Good luck!
After i tried like almost the entire day i got the tablet in rescue mode or fastboot mode..
I've wiped/data or factory reset and the same happens... it stays in a loop when boot at logo.
I've let it to do so until the battery went dead from 100% and still the same.
I have official ROM but can't install it at all. I think the bootloader is locked?! And it doesnt even unlock it when using some fastboot commands
Also can't install nothing from SD card and when tryin to use ADB the PC can't see the device, but when using fastboot I can work on it.
In rescue mode i've done some root integrity check and at the end of the check some /system files are modified. I believe this is causing the entire problem.

Typically, on devices I know of, it's fastboot that you would use to flash factory images. So you should be good there. But again, I don't know if that is how your device works too. And it would also typically not matter what's been altered on your device, system wise, you would simply flash the appropriate images with fastboot.
So I'd still say you need to determine the correct procedure to flash the files you got from their site. Perhaps there site has instructions? Or a support number for help of its not working as it should?
I've talked with the support. They gave me a link with an official ROM, a different one that the one that was from the site. But they didn't even told how to use it, LOL.
Have the damn files and don't know what to do with them, OMG.
I've placed the zip archive on SD card and tried to use the option from rescue mode with 'update via sd card". The zip archive is visible but after i select it says Installation aborted :|
I've googled around and maybe my tablet needs to be at over 50% power... but it was plugged into the wall it should've worked.
edit: 100% and no good...
edit2: they sent me another e-mail with a pdf file in which it is explained how to flash their device.
Hi Guys,
I got a Moto Z from US recently(I live in Asia).One day I was charging my phone.I got uncomfortably hot.So I decided to power off my device and when i restarted it,it got stuck on bootloop.I did try factory resetting my phone and then went to Motorola Service Center.Even though it was under warranty they refused to service it because it is from another country(Even though I agreed to pay $300 they were charging for a MoBo replacement.
After any hope of getting the device up and running,I tried to update the device in fastboot mode.I made the mistake of using an older firmware thereby Hardbricking my device
I did manage to get it to back to life by using this file
https://forum.xda-developers.com/mo...-to-unbrick-moto-z-hardbricked-t3590133/page2
(post#18)
Step 1: If your PC detect the phone as QUSB_BULK device, install the drivers provided. If it detects it as qualcomm device 9008 or something, then move directly to step 2.
(If your PC is not detecting your phone then try removing the battery and then plugging it back on. Connect to the PC and press the power+volume down button for 2 minutes. Keep trying this this with different USB ports until the PC detects it.)
Step 2: Now extract the blank flash file and run the 'blank-flash.bat' file. Your phone should boot into fastboot now.
Step 3: Now you can flash your stock ROM or any custom ROM. I suggest you flash TWRP and boot into recovery and flash a custom ROM first. And then flash the Stock ROM later if you want to because flashing stock rom is very tricky in Moto devices and you can end up screwing your device even more during the hardbrick phase.(thanks to:manish54 ,benzinerwin)
Then I started to update the stock ROM.But it wont take any gpt.bin(GUID Partition Table) files.
(error)Preflash Validation failed
Without GPT I cant update anything at all.If anyone can help that would be great.
I do not have 10 posts yet, remove underscores from urls. I will edit this when I have 10 posts, I'm sorry for the slight inconvience.
Hi, new here! I recently acquired a Motorola G7 (xt1962-1/river_amz) from my sister. The device did not boot. It mentioned that the device did not start-up successfully, something in relation to slot/a and slot/b, and that I needed to utilize a Software Repair Assistant.
Non-Verizon devices cannot utilize this Software Repair Assistant, I tried and it hung at Processing Device Info. For Non-Verizon devices there's a piece of software called Lenovo MOTO Smart Assistant which can be found: https://support.lenovo.com/us/en/downloads/ds101291
This option did not work for me as the Bootloader did not for some reason allow the device to overwrite some of the content (permission was denied device side.)
The MOTO Smart assistant was good for downloading the devices software. So you do the following:
Download and install the smart assistant software
Click the flash option and then the rescue option
Click moto phone
Select moto g (7th gen)
Select xt1962-1 and then next to target and firmware name there's a download button press that and the firmware will start downloading
You can follow the onscreen instructions for that program, like I said however, it didn't work for me so I'm just going to tell you the steps I went through to get the device working. If you have other solutions, I, as well as the rest of the MOTO G7 users will be happy to hear what worked for you I'm sure.
I tried downloading the files from /moto-g7/development/moto-g7-river-xt1962-1-firmware-29-114-t3913673 on this site and flashing those with some of the below mentioned methods but, no dice.
The default firmware download directory is C:\ProgramData\LMSA\Download\RomFiles btw.
I didn't want to fuss with trying to get RSDlite working on Windows 10. I found that an older PC with a 32-bit install of Windows 7 was far easier to manage, so, that's what I went with.
To follow what I did:
Download RSDlite 6.2.4 from rootjunky's site via: http://rootjunkysdl.com/files/?dir=Android Programs
Download 32-bit drivers from: http://rootjunkysdl.com/files/?dir=Android Drivers/Motorola if LMSA did not install them already
Copy the firmware folder to your desktop or somewhere easy to work from
Ensure your device is in bootloader mode
Open RSDlite and your device should be detected
Select the firmware folder and open flashfile.xml with RSDlite and press start
Let the process finish and don't interupt or you will have to do it all over again
The phone should boot, you will more than likely have to sign into an google account that's already been in use on that device (due to FRP)
You can also use the XML to BAT method, that didn't work for me (remote permission denied/device side)
I hope this helps some people who struggled like I did. Also, sorry if some things are badly worded if at all. I'm autistic and have trouble explaining and expressing things.
Check out my stock resources thread: https://forum.xda-developers.com/moto-g7/development/riveramz-stock-resources-t3917937/
Worked perfectly!
Thanks! I had the same issue (my wife's Moto G7 stuck at the bootloader) and was able to follow your directions, so much appreciated.
The only change I made was to follow the directions at this video (go to youtube/watch?v=njXQYn53SPc) to perform the XML to BAT instead of using RSDlite (since I was on Windows 10).
It worked perfectly and fixed the issue--and the great thing was that by converting the servicefile.xml instead of flashfile.xml, I was able to retain all the data on the phone.
The overall sequence of steps (listed in detail, since this was my first time flashing. Remove underscores from URLs):
Download Lenovo Assistant from your link
In Lenovo Assistant, go to Flash, then Rescue, then select model of phone. Click to download the firmware (but do not actually click the "rescue" button).
Download Google's Platform Tools (to get fastboot and ADB)
Make a folder to hold everything (called "flash")
Copy the downloaded firmware folder from C:\ProgramData\LMSA\Download\RomFiles to flash folder. Copy the fastboot, adb, and adb dll's from the Platform Tools to the firmware folder (per the video).
Copy and edit commands from servicefile.xml to a new servicefile.bat, as described in the video. Place this file in the firmware folder.
Run batch file in command prompt from the firmware folder.
That got the phone running again, with all data intact.
Thank you so much, worked like a charm.
Mine doesn't seem to have any partitions anymore. All my phone does is fast boot mode. And it won't let me flash anything... Please [email protected]

I followed sd86's guide and used servicefile.xml instead of flashfile.xml, as suggested by chi2.
No problems whatsoever installing RSDlite 6.2.4 on Windows 10 x64 (1909). The drivers were installed by LMSA and I have no idea why you guys said it was difficult.
Just for the record, my phone is a Motorola G7 (xt1962-4), that out of thin air started showing the following message:
start up failed
your device didn't start up successfully.

When slot A is active and you flash Lineage OS using TWRP, it writes to slot B and switches to slot B.
When you reboot, you cannot boot anymore, because on slot B there is no bootloader.
To mitigate this issue, you have to flash a "copypartitions" zip before rebooting.
My phone also was in 9008 mode and I revived my Moto G7 using the blankflash method, see here:
https://forum.xda-developers.com/mot...reteu-t4020263
I can also confirm saving my Hard bricked, non booting black screen, no life moto g7 with the above blank flash app from above link. then i used the lenovo recovery program to put the original rom back on the phone downloadable here: https://support.lenovo.com/us/en/downloads/ds101291
if you have a black screen hard brick, no life but windows 10 sees it at an unknown or 9008 device then you can bring your moto g7 back to life again. follow all the above links and youre good!
I don't have a Windows 10 PC...plus, if I screw up my phone, I'll catch hell from the wife...lol
SO...that being said, if someone has an XT1962-6 'River' RETIN phone running Android 10 w/June Sec. Patch....I'd be willing to 'donate' to their paypal for a copy of my phones fw! Anyone interested plz pm me. Thx!
Good day, your post was very useful for me, bring back my phone, Im very grateful, thanks, sorry for my english
switch off your phones and connect usb.
first install drives to your pc by searching where to find device drivers motorola
then download lenovo smart assistant and press rescue
Hi. Im new here too. Well been for a while just my second post and the first time iv actually been able to flash a rom. I have the same problem. No bootable slots. I know exactly what i did wrong. I knew it the moment i hit the reboot button. However, i run zorin 15 on my pc and the levono assistant don't support linux. Anyone know where i can acquire the assistant running linux? Greatly appreciated in advance.
Thank you very much sd86 and chi2 for your research and help
Sadly my phone can't boot after flashing clean OS
I don't want to erase UserData partition, but it seems error is there (as it's only left partition untouched).
As I still would like to keep my data (this is the most important thing on our mobile devices) the only one hope is to unlock bootloader, flash recovery partition (eg. with TWRP) and then perform a backup from recovery software.
Hi,
so with this Tutorial i was able to unlock the bootloader of the Blackview tab 8.
but i just could not find any way to flash magisk.
- "fastboot boot patched_img.img" and "fastboot flash boot patched_img.img" gave me "fastboot: error: Couldn't parse partition size '0x'"
- "fastboot flash:raw boot boot.img" was able to flash the patched_boot.img (a twrp i tried to port as well), but then i was stuck at blackview logo (SOFTBRICK)
- SPD Research Tool R24.0.0003 was able to flash patched_boot.img, but same stuck at logo (SOFTBRICK)
The only way i was able to unbrick it, involved opening back cover and disconnecting the battery and reconnecting it again.
then put research tool to download mode and flash stock img
I'm hoping for some advices, what i could try to get magisk flashed
- Tab8 Firmware (DK_SC9863A_P30_5G_10.0_Tab8_EEA_20201022_V1.0)
- SPD Research Tool R24 (there are 2 other tools but afaik research tool is the only one, where i can choose which partitions to flash)
best regards

Hi,
I've got a tab8 too (eu) and I have the boot_patched.img generated by magisk manager but I can't unlock the bootloader. I used the tuto you gave (your first link) too.
Could you explain what you did to successfully unlock your bootloader please?
Thanx
Bests regards
I was trying to backup the stock ROM of this same tablet, however i must have incorrectly installed SPD drivers or somehow had uninstalled them, Research Download said "failed user cancel", then boom when i tried to switch it on it was not turning on nor charging. I have been trying to charge it for about 4 days, no dice, it does not charge still, nor turning on.
I must have soft bricked it, because it gets detected by the PC as "SPRD U2S Diag (COM5)", but when i try to flash Stock ROM i downloaded it either says " failed user cancel" or gets stuck at "checking baudrate".
I don't know what to do, would opening it and test point it make a difference? Because some guy on Youtube was able to flash his SPD phone after test pointing it, as it was facing "failed user cancel"
Another question, which key combinations did you use when flashing your Tab 8? Vol - and Power or?

I did it like described in the tutorial i linked. did you use linux? maybe in a VM or so, to use the .sh script. AFAIK it doesnt work with windows
also dont forget to activate "OEM unlocking" in dev options

i dont know about test point actually. you can open it pretty easily and just disconnect battery. then connect again, use sdp tool and start the flash process, then press vol- and hold it while pluging in usb cable. thats what i do, if im stuck and cant do anything else.
regarding button combination, i'm not sure. usually i use adb reboot bootloader.
Also for the Blackview Tab 8 you need to extract keys from your vbmeta.img and sign it differently, also every other .img you wanna flash, like patched magisk boot.img. i successfully rooted mine some time ago, but i flashed some magisk modules and something went wrong and i ended up bootlooping. now im trying to root again.
somehow i cant flash the vbmeta.img. i dont remember if i did anything different last time.
all the stuff i did to get it rooted, i have taken from that hovatek forum.
edit: uploaded Stock Rom Images and stuff like for example a magsik patched boot image, which got repacked with android image kitchen then signed and repacked again with avbtool here
PS: dont have time to invest to this atm, also i just read that there was a update sometime this year which i didnt get, so maybe that changed some stuff.
I was considering buying this Blackview tablet and before I ordered it I got in touch with the Blackview home people in Hong Kong. They were extremely UNHELPFUL AND EVEN RUDE (not unusual for the chinese). As far as I am concerned this mob does not deserve to be supported and having a product that is so difficult to do any tinkering with precludes it from my list for sure. It is so time for consumers to DEMAND that any product that does not give explicit instructions as to unlocking and flashing is not supported. Why is it not possible in this day and age for this to happen. OK I know why but you get my meaning.
