Since you have a upgrade file, place it on the root of the USB drive and make sure it's formated in FAT32 before applying the update.

Kindle Fire Stuck Logo

Hello all, please forgive me as I know there are a ton of threads with a similar title but I'm completely new at this and I'm frankly at a loss.
My Kindle Fire is stuck on the Kindle Fire logo screen after trying to unroot it. I know I messed up by trying to wipe everything off of it and rebooting it. I'm hoping someone can walk me through a step by step guide on how to unbrick it (I am completely dumb with this and probably shouldn't have attempted to unroot it in the first place).
I recieve the following error when trying to do anything in the KFU or the Unbrick Utility:
exec '/system/bin/sh' failed: No such file or directory (2)
Unable to access the internal portion of the Kindle Fire, when I try to "Browse Files" it's grayed out with no option of looking into it. When looking at the device itself, it's on the dimmed light Kindle Fire logo with the power button showing green.
well unfortunately you will need twrp and fff back on your device to do it... if you cannot get it into fastboot very likely you will need a factory cable to do so found here http://forum.xda-developers.com/showthread.php?t=1392693 after you get twrp and fff back on simply wipe everything except your sdcard or external storage and flash this rom http://forum.xda-developers.com/showthread.php?t=1439916 then you will be all refreshed and can decide where to go from there...
Edit:looks like at this point he has 5 cables maybe less left best jump on that as soon as you can... in the meantime keep it on the stock wall charger as not to compound the situation with a depleted battery...

Thank you for the response.
How does the cable work though? Does it work just by plugging it into the device? By using it and the Kindle Fire Utility I would be able to install the TWRP at that point? Also how do I flash a rom onto it when it is in TWRP? Kinda confused what flash means sadly..
Dont feel bad.. this is what I had to do to get the cable to work for me when I tested it: shift + right click on the tools folder in kindle fire utility.. select open command window here...hold down the power button on the kindle for 30 seconds to power it off , dont plug it in yet type
Code:
fastboot -i 0x1949 getvar product
in the terminal hit enter.... then plug the kindle in ... it will then power on in fastboot and return product:kindle in the terminal... this is if all your drivers are installed correctly if this is the very first time you have tried anything with your kindle I suggest you get at least a 2 gig usb flash drive and go this route....

to better answer this question the cable forces the devices into fastboot so that things like bootloaders and recoveries can be easily replaced when there doesnt appear to be another way to do it. As far as flashing goes it pertains to flashing a rom flashing a recovery ect. In most instances it just means replace without a better term for it...

Cannot start Fire TV 2 - TWRP settings that may help?

Hi there
I have an Amazon Fire TV 2 (4K) which I have rooted with rbox's pre-rooted ROM with custom recovery etc. All has been going well and I have been working on perfecting my Kodi install when this morning I snagged the power cord and the Fire TV fell about two foot off my sofa on to my carpeted floor. I honestly didn't think there would be a problem, but the unit restarted and got stuck on the white Amazon logo.
I left the unit completely unplugged for an hour and tried again, but it was still stuck on the white Amazon logo. I still have recovery so I immediately backed up my system in full onto my microSD card, then tried wiping just the cache (to make my life easier if this worked). The process seemed to work except for a message in red which said "unable to locate boot partition", but sadly when I rebooted I was still stuck on the white Amazon logo. I then tried a full factory reset, which ran without error, but still left me stuck on the Amazon logo. I then flashed the pre-rooted ROM (sloane-5.0.5-rooted_r4), which also seemed to work, but still resulted in me being stuck on the white Amazon logo.
Is it possible that some small part of the machine broke in that short, fairly soft fall? Or is there something else I can try via TWRP?
If the hardware is at fault, I would prefer not to return it to Amazon rooted and with the stock firmware installed, so would I be able to wipe it 100% if necessary. I do hope it doesn't come to that, but if anyone has any ideas, I would be very (very) grateful.
Peter
In the last sentence I meant to say, "I would prefer not to return it to Amazon rooted and with the custom recovery installed..." Just in case that was confusing. Still keen to find an answer if anyone can help!
Left the Fire TV unplugged all night. No difference today. Looks like I'll have to return it to Amazon with the glaringly obvious recovery mode staring them in the face when they come to test it out. I just hope they don't balk on issuing a replacement. It would have been nice to be able to try out a few more methods before giving in, but I see my post has not rung a bell with anyone.
Now that you've flashed a pre-rooted rom over your old one, can you unplug everything (including sd card, hdmi cable, power, ethernet) and leave them unplugged for an hour or so, then try again?
Thank you for your response. I shall certainly give that a shot and report back afterwards.
Hello again. I left my Fire TV completely unhooked from all peripherals for well over an hour, but still stuck on gruesome white logo. For good measure, I tried reinstalling my backup. Ran without issue, but still stuck on logo. Then reflashing pre-rooted ROM, but again stuck on logo.
Is it possible that a tiny memory module of some kind was dislodged in the fall? It seems so strange that it still powers on and I can still reinstall from SD card etc.
I would much prefer to exhaust all options if possible. Unless there is a foolproof way to confirm hardware failure.

Thank you, sir. I'll be honest I came across that article on my travels in search of an answer, but assumed it was for people who didn't have recovery. I shall certainly give it a shot and let you know my results.
Good morning. I was too tired to try this out last night.
Having read through the entire FireTV 2 Unbrick Image thread it is not 100% clear exactly what steps I should take to run the process. Once I unzip all the files do I simply drop them all in the root folder on my SD card (in the Fire TV)? And do I then attach the Fire TV to my Windows PC via USB?
Lastly, if I already have recovery, do I really need to go through this process, which may very well lead to further issues, only to get me back to square one and the recovery I already have?
I'm so sorry to have to pester people about this, but without your help I would be lost.
OK, my brain is waking up. As far as the files go, I just put the unbrick.img on my SD card, then run the remaining files on my Windows PC and connect my Fire TV via A-A USB cable. OK, I can do that.
But does it all just lead to the same recovery?

READ POST: "Extract all 3 zip files to the same directory." and yes it will
I truly appreciate your help.
OK, so I have placed the file "ramdisk-recovery.cpio.lzma" on the microSD Card and returned the microSD card to the Fire TV. I ran "unbrick_firetv2.bat" on Windows, then connected my Fire TV to my PC via A-A USB cable. Windows recognised that there was a device, but did not successfully load any drivers ("Device driver was not successfully installed - MT65xx Preloader - Device Unplugged") and the Command Window in Windows simply states "Waiting for preloader" and nothing else happens.
I already have ADB drivers on my machine which was working with my Fire TV before the problem began (15 Seconds ADB Installer 1.4.2), so how can I get my Fire TV to communicate with my Windows PC in order to initiate the process? Or is the trouble I am having indicative of a hardware problem?
I await any and all input.

1) create a folder on your desktop
2) unzip all three files in this new created folder
3) connect your firetv through an A-A cable without power cord connected
4) Run unbrick_firetv2.bat for Windows or unbrick_firetv2.sh for Linux or OSX
5) power on your firetv unit
6) let the process run
Note: you need to install the proper drivers before you do any of above steps. Follow step 2 in this link: http://www.aftvnews.com/how-to-root-the-amazon-fire-tv-2/
Hello again. I did all the steps outlined above. The main factor I was missing was installing the MTK65XX Preloader USB VCom drivers.
This proved to be the usual despairing pain, but I got there in the end, installed the unbrick image, then reconnected the Fire TV and booted into recovery without issue. I then flashed the pre-rooted ROM without issue, but - so very sadly - I am still still stuck on the white Amazon logo.
Can I safely assume now that my unit is simply broken? If so, how can I delete all signs of the recovery and root, so I might say to Amazon it didn't start after a factory refresh?

Have you used unbrick.img or unbrick+ramdisk.img? BTW what version of prerooted img did you use? Maybe that is the cause, could be corrupted.
I used "unbrick.img" because I have a microSD card and it took half an hour as opposed to two. The pre-rooted image I used was "sloane-5.0.5-rooted_r4", which I have had in a folder on my PC for over a month and have used successfully several times before so I don't think that is the issue.
If there are no other options, I think it's time to get a replacement, but how do I wipe recovery and root so I don't have to explain myself to Amazon?

I do appreciate you trying to help, but this all so tricky and time-consuming. I already had recovery, I then installed recovery again with the unboot image. What difference could installing recovery the slowest way make?
OK, I am trying the long way now. I suppose I said I wanted to exhaust the possibilities.

If you install kingroot on a Windows PC and then plug that into the Amazon device.
If you set kingroot to automatically root your Amazon device it should automatically reinstall the factory image if it fails to root it for you.
This is how I unbricked a fire TV stick. I understand that this is a full fire TV, however if you are stuck what have you got to lose.
Alternatively if you have installed TWRP, then you should be able to mount external devices and install the factory image from there yourself...

hi bro
i hav now fire stick that don't update it stuck om update screen and go no further can not allow me to get to registration .
i tried to use king root but the pc dod not recognize the fire stick so the process did not happen how to do it thx
can not connect to adb or anything but can connect to a wifi
Sorry for the late reply on this, I only just saw it when I installed xda labs.
Firstly use Windows 7 or 10, which version did you use? Secondly you will need to follow the respective instructions to install kingroot. For instance Windows does not come with complete USB drivers and needs to install Android drivers for each device. You can get round part of this by installing the Android SDK which includes a repository of most drivers. Test it is working first with a phone or tablet.
I assume you have the internet enabled on both the windows device and fire TV stick? You will probably also need to ignore any false positives from virus guard software during the process and temporarily (keep it safe by avoiding doing anything else on the internet!) Turning off your firewall.
Finally kingroot has many fake copies floating around! Only follow genuine threads from xda. (I would give a link but have noticed they change from time to time because of the nature of these apps).
I have successfully un-softbricked both my fire TV sticks using this process. Good luck!

*Solved* FireTV 1 Gen - Rooted/Unlocked BL/Pre-rooted 5.2.7.2_r1, can I downgrade?

Basically I want to downgrade from rbox's pre-rooted version 5.2.7.2_r1 back to 5.2.6.3_r1.
I use ADB via Windows 10 with no problems, I've access to SU, FireTV is rooted and TWRP 3.0.0.7 is installed.
In the past I would just boot into TWRP recovery and select any of rbox' pre-rooted rom and hit install/upgrade and all went well since 2016.
This is the first time trying to downgrade, TWRP recovery went well 5.2.6.3_r1 got installed, but no way to login into my Amazon A/C (kept saying login/password combinations not correct, but they were 100% correct).
One thing interesting is before I could see my bootloader as fully unlocked as "[email protected]", but now I see its only partial unlocked ([email protected])?
Update:
It seems like I do have rooo#bueller? from this picture after typing adb shell and su?
Any help will be much appreciated!
In regards to your original post on the bueller thread - have you tried re-enabling updates? A few other members here found that disabling updates on their sloane (see here) stopped them from using particular apps on 5.2.7.2 until they re-enabled updates, allowed the Fire TV to download updated apk files & then disabled them again
If that doesn't work: I had a Fire TV recently that I thought it was blacklisted by Amazon (wouldn't log in with the correct details), but turns out it was just never registered as a AFTV on their end & was being refused a connection. This obviously won't be your case, but something similar could be happening, so I would suggest you remove the device from your account (here: https://www.amazon.co.uk/hz/mycd/myx#/home/devices/1) & then attempt to log in again - if this doesn't work, maybe talk to Amazon via their live chat, ask them to register your device to your account manually (they'll happily do it) & attempt login again after a hour or two (that worked for me).
edit: I've just seen your latest post about bricking - general rule of thumb (as far as I'm aware) is that anything after 5.2.6.8 shouldn't be rolled back to pre-5.2.6.8 due to changes within the partitions, therefore, if you do so, you essentially brick your device after reboot as the prerooted zip only flashes boot/preloader/LK, then at boot, the rpmb checks to see if all those files match & when they don't, sends the device into a bootloop. If this was a Fire TV 2, you'd be in luck, but unfortunately, there doesn't seem to be any way to unbrick a Fire TV 1 on the latest software yet?
If you're bootloader unlocked, you might be able to get into fastboot & fix it from there, but I'm not clued up on the Fire TV 1 bl unlock unfortunately.

Completely right for the second gen fireTV :good:
But the first gen fireTV isn't a MTK SOC device, the SOC is from broadcom with different booting stages. In case of a rooted box, you can up- & downgrade to any fireOS 5 version if you like.

There is a way, but it requires hardware (low voltage emmc adapter, a special sdcard reader, small soldering iron) and at least some soldering skills.

Some guys have tried it, it's all in the bueller prerooted rom thread.
Hi Daniel, thanks for taking the time to write.
Yes my bootloader is fully unlocked, and my unit is rooted with TWRP installed.
Hi Sus_i, where are you at? If you can try the "hardware (low voltage emmc adapter, a special sdcard reader, small soldering iron)" thing on my FireTV, I will compensate you for your time and ship the unit to you (I'm near the border, so US/CAN addresses are fine with me).
Ok, this is what happened in my case:
My FireTV 1 background - bought directly from Amazon, rooted back in 2015/2016, bootloader fully unlocked and TWRP installed in 2017.
1) Was running on rbox's pre-rooted 5.2.6.3_r1
2) Updated to rbox's 5.2.7.2_r1 and discovered that upon resuming/waking up from sleep the unit always return to the Home page instead of whatever page/Tab you left it as in 5.2.6.3_r1, also Alexa and few other APPS were automatically installed in 5.2.7.2_r1.
I only use 4 APPS on my FireTV, an APK from my IPTV (90 %), VLC to watch videos from my own local Network (5%), CX_File Explorer to move/transfer files (3%) and NewPipe (alternative to YouTube) (2%).
rbox’s pre-rooted 5.2.6.3_r1 is perfect for my needs above, as I NEVER need to see the Amazon Home screen or any ads. Only the 1st time after a power off/on that I would ever see the Home page and from there on I would navigate to the “Settings” Tab – “Applications” Tab – “Manage Applications” and I only see a few pre-installed APPS from Amazon and my 4 APPS above and going to sleep mode and waking up sleep mode always stays in the “Manage Applications” Tab and NOT Amazon Home page as in 5.2.7.2_r1.
3) Flashing back from 5.2.7.2_r1 to 5.2.6.3_r1/5.2.7.0_r1/5.2.6.9_r1 to no avail because I would always get an error stating Login ID/password combinations were in errors (Login ID/password were 100% dead correct), also the Developer Options would also no longer showing under My Device/My FireTV Tab. Amazon FireTV support would be quick to add the FireTV under my profile (because they could see I bought it directly from them back in 2014 and they also could see my serial numbers and all along I was the only one registered for this unit), but still no go, so I tried to de-register/re-register again during all the testing and Amazon must had added the FireTV to my profile at least 10 times and in the end it escalated to the point they credited my account $25.00 (this is usually the price of the FireTV Stick 4K during sales/promotions) and also at the same time sent out a FireTV Stick 4K to me FOC.
I’m not a FireTV expert, but just an ordinary user with some sys/programming backgrounds during my early years. I reckon Amazon must had implemented some sort of hard coded checks either on their side (registration) or in the firmware since 5.2.6.3_r1.
4) So now my unit is flashed with 5.2.6.3_r1 and couldn’t get passed the registration screen, what do I do? I re-flash it to 5.2.7.2_r1 and bingo, everything is back to normal again and don’t even need to register the unit. (For testing purposes, I removed my A/C from the unit and re-register again and this time Login ID/password got no errors).
5) Thinking that back from Windows 98SE/2000/XP Pro/W7 Pro and now Windows 10 Pro, no matter what kind of messed I created, I would just format the drive/write zeros and re-image (Ghost image Back-ups) and everything would be normal again. My fireTV is rooted, bootloader is fully unlocked and TWRP installed, I told myself what’s there to afraid of , so I tried to re-flash 5.2.7.2_r1 to 5.2.6.3_r1/5.2.7.0_r1 and it would always back to the registration error and now double icons under settings, lol.
6) I suspect during one of the re-flash I made a mistake of after clearing/wipe Cache/Dalvik, instead of the default reboot, I ESC back out and redo the install/re-flash thinking that might get rids of all the leftovers that cause the double icons under Settings.
7) Now I’m left with the white Amazon logo on my TV screen and white pulsing light on the unit itself. I like to think that the motherboard or the power unit are still alive, just that the software part of it got messed up by ME big time!

Like DanielF50 said, as a first step you may try to connect with fastboot, use an usb a-to-a cable and run: fastboot devices

Good information to know, thanks Sus_i :good:
Reading Matt's response, it looks hopeful that he should be able to fastboot into the device to recover it then.

OK, I'll get the USB A to A cable, how does one run the fastboot?
Once I connect the FireTV to my PC using the USB A- A cable, what will happen? do I need to install anything on my Windows 10 to run fastboot?
Update:
OK, dfound out I already have fastboot in my platform-tools folder,
From AFTNews:
Enter the command:
fastboot devices
If your computer has correctly detected your Fire TV, you will see a series of numbers followed by the word “fastboot” after entering the above command.
Download the latest version of ClockworkMod custom recovery from AFTVnews.com/recovery
Rename the file you just downloaded to “recovery.img”
Enter the command:
fastboot flash recovery recovery.img
(Be sure to replacerecovery.img with the full path to the file you just renamed)
Enter the command:
fastboot boot recovery.img
(Be sure to replacerecovery.img with the full path to the file you just renamed)
Your Fire TV should now boot into ClockworkMod recovery. Proceed to follow the steps in the next section below labeled “Resetting with Recovery Mode”.
Resetting with Recovery Mode
If you can successfully enter ClockworkMod recovery, then follow the below steps to reset your Fire TV, regardless of what state it is in and what has been done to it. You can also follow these steps if, for example, you want to update your ROM but aren’t sure if you’ve unlocked your bootloader or aren’t sure if you’ve installed the boot menu.
[OPTIONAL] From within ClockworkMod, select the option to “wipe data/factory reset”. This will delete all of your settings and user data. It is an optional step, but is recommended.
From within ClockworkMod, select the option to “wipe cache partition”.
Follow my guide to install pre-rooted Stock ROM version 51.1.4.0_514006420 updated. Note, you are NOT installing the latest pre-rooted ROM on purpose. Do NOT skip ahead and install the latest pre-rooted ROM.
Restart your Fire TV. You should be able to boot normally.
Follow my guide to install BusyBox.
Follow my guide to unlock your bootloader.
Follow my guide to install the boot menu.
Follow my guide to install the latest pre-rooted ROM.
Do I need to redo all these? I already have TWRP. If I'm to do the above I would end up with both TWRP recovery and ClockworkMod custom recovery, right?
Once done, do I actually install the 51.1.4.0_514006420 updated or 5.2.6.3_r1?
Pardon my ignorance!

OK, I'll get the USB A to A cable, how does one run the fastboot?
Once I connect the FireTV to my PC using the USB A- A cable, what will happen? do I need to install anything on my Windows 10 to run fastboot?

Yep, bundled with android-sdk so runs just like you'd use adb, but obviously has a different purpose/commands - I should think there would be info on the full bootloader unlock thread on how to use it to recover from a bootloop using fastboot?

You can try to boot the recovery.img (boot... not flash!)
This means, grab the latest prerooted, extract the recovery.img into the fastboot/adb folder. Check/connect with fastboot devices and run: fastboot boot recovery.img
In case this fails, you may carefully follow the guide you've posted above.

OK, will try and report back.
I actually made a copy of "bueller-twrp_3.0.0-7.img", "bootmenu.img" and "recovery.img" which I copied from the FireTV before flashing, I reckon I can use the "recovery.img"?

Update 3:
Gosh, I got it to the point of checking for updates and unplugged the internet cable hoping to issue via adb to block OTA, and the FireTV detected no internet connection and asked to unplug the power for a few minutes and I did that, but now no whatsoever light on the FIreTV itself, don't tell me its now dead not because I bricked it the other day, but because of the power unit?
Tested the power adapter with a multimeter, got 6.18V (6.25 is printed on the power adapter), since 6.18V is close to 6.25V, its not the power adapter right?
Update 2:
OK, figured out I could remove the USB A to A cable and use the USB port on the FireTV to connect my Logitech K400 ! (see, I'm not a very smart person!)
- I deleted "Data"
- Tried to wipe cache and got a message "No OS installed"
- No choice but to select install option and install 5.2.7.2_r1
- Now at least I'm seeing the Colourful Amazon logo again, and now its doing the "Optimizing system storage and applications...", wish me luck!
Update 1:
Just received my USB A to A Male to Male (LOL) cable today.
Don't know to jump for joy or cry!
- When I typed "fastbbot devices", I got exactly from "AFTNews - If your computer has correctly detected your Fire TV, you will see a series of numbers followed by the word “fastboot” after entering the above command.", I got the screen showing me my device/serial number and the word fastboot, so I think its working!
- I then typed "fastboot boot bueller-twrp_3.0.0-7.img" and the white Amazon logo was gone I was back in TWRP screen, but I couldn't do anything, the USB port is already used by the USB A to A cable (USB splitter couldn't work either), I see the mouse pointer, but how to move it to reboot/wipe/install/advance etc?
Mayday, help!

Pull all the plugs from the box + tv and try again...
6.xx v seems ok. Any voltage drops if you connect a device, light bulb or anything like that?

Thanks Sus_i.
How to connect the light bulb to test, and connect from where to where?
I couldn't believe what a stupid move I did by pulling the internet cable and now I want to beat myself so bad...
I've a few power adapters from router/modem etc lying around, will I damage the Fire TV if I'm to try them out?

Have you tried to pull all plugs, reconnect only the power supply... what does the LED?
There is an ifixit guide on how to disassemble the fireTV. In case you open the box, measure the voltage IN inside the fireTV at power on. You can measure VDD 3.3v and VDDQ 1.8v too, next to the emmc, see the picture here.

That shouldn'd harm anything. In case of a failure, the fireTv should blink yellow.

You can test other adapters, someone on this forum said that he used an 5v usb supply, but for a 'stable use' you need a big one... regards the amps...
I think a power supply between 7v to 5v works fine, probably no damages at all.

OK, will try to open up the FireTV.
No light/LED when plugging only the power adapter to the FIreTV, already tried different power outlets throughout the house
Come to the worst, will this https://forum.xda-developers.com/showpost.php?p=66961740&postcount=676 help?
Thanks again.

Worst case is a broken fireTV.
Don't follow this guide, you lose your unlock... apart from that, the download link from the guide is dead

OK, will forget about that!
Once I got the FireTV opened, will take some pixs and report back!
OK, here are the pixs.
Now that I look at the Multimeter, I'm not sure I'm using it correctly. Bought this few years ago (just in case I need to test my car's battery).
AT the bottom of the multimeter, there are 3 holes, one red on each side and black hole in the center, which two am I supposed to use?
I tested the power adapter again with multimeter using the center black and red on the right, and I'm reading 4.2V?

Would it be possible just by looking at the board if its kaput?

Help me unbrick my Kindle Fire Gen 5

Hello! First post here so please be gentle.
I am trying to resurrect a bricked Kindle Fire 5th Gen (Model: SV98LN) after a failed attempt at rooting using a Root Junkie tool. I was trying to get vanilla Android on it. Anyway.. it's apparently dead, showing a black screen and no attempts to turn it on have succeeded. It's probably hard bricked.
I've done quite a bit of reading and tried various things:
- making up a factory cable for fastboot mode
- installed Mediatek SP drivers so as to reflash the MMC (on Win10)
- tried to access the Mediatek 65xx Preloader on a Linux machine using aftv2-tools
..so far nothing is working, but I do see the Mediatek device appear on the Windows device manager momentarily (it disconnects with "failed to read device descritor" or some such) and also I can occasionally see it on the Linux box with lsusb. But that's all.
Could someone offer a bit of advice, please? I know there's a lot of information out there about this but I've spent a solid day ploughing through threads, dead ends and other unuseful information and I can't find any solutions myself.
Many thanks
Jon

If you have a 5th gen Fire codename Ford/KFFOWI.
Do not use a factory cable(fastboot cable).
There is a unbrick and bootloader unlock method.
See the 5th gen forum
Amazon Fire
The Amazon Fire is a budget tablet released in September 2015. It runs on Amazon's Android Lollipop based Fire OS 5, which provides easy access to Amazon's online features. The Amazon Fire has a 7" 1024 x 600 display, 1.3GHz quad-core processor, 1GB of RAM, 8GB internal storage, microSD...
forum.xda-developers.com
Following https://forum.xda-developers.com/t/...ick-downgrade-fire-7-ford-and-austin.3899860/ I have got it into (hacked) FastBoot mode. It's displaying an Amazon logo and says "=> HACKED FASTBOOT: (0) - xyz, k4y0z"
The next step in the procedure is to call the fastboot_step.sh script, but each tiome I do it errors out with 2symbol lookup error: fastboot: undefined symbol: _Z15ErrorCodeStringi"
I'm going to also look at the link you posted, thanks.
Seems to be a problem with my fastboot in /usr/bin... not sure how to correct it. apt-get reports it is fastboot 1:8.1.0+r23-5~18.04 and says it's the latest. Is that right?
