I recently released a fix for the 403 Forbidden Error within Downloader app on Android TV/Google TV boxes.
Some of you who have blocked Amazon updates are also getting this on your Fire TV devices.
Here’s a fix that MIGHT work…shot in the dark. This is hard for me to troubleshoot because I don’t have a Fire TV device giving me the 403 Forbidden Error.
If you try what I show in the following video please provide your findings in the comments below.
Thank you!
Well, the download that you linked did work and install. But the same old 403 error was still there. I did do the install and then rebooted the Firestick just to be sure the new file was loaded. But same old 403.
I did give an attempt to go to the toolbox via the silk browser. I could see the page and click on links using Silk. But downloads are indeed blocked. 
For now, the only workaround is inconvenient but it does work. I can download the files I need from the tool-box on my PC and put them on a USB stick. Then using an OTG “Y” cable to expand storage on the Firestick, I can sideload the files. Better than nothing, I guess.
Thanks for this info. Assuming VPN is off on your device as well? What Fire TV are you using?
Also, someone else commented that they had expanded internal storage on their device and they had previously transferred the Web View app to external storage and that was also causing problems as no way it could be updated from there. They moved it back to internal and everything was fine.
Yes. I tried to keep it all as simple as I could. No VPN running. The file downloaded from the shortcut fine and then did its normal install as with any file & Downloader.
This is a 4k MAX. I do have an old Gen 2 Cube in the closet. I might bring that back out and see if it behaves differently.
I got the dreaded 403 error on my Firestick that I hadn’t yet blocked updates on. I was going to apply the hack, but I can’t get to your Toolbox no matter what I try. I’d love to know how to resolve this.
Hello, I don’t use the toolbox in the above video. I would suggest just trying the code that I show in video.
Ive run into this but i simply move to another country on surfshark let ot connect to the “new” location and then load what had been giving me issues . Give it a try.
I had the same 403 problem prior to blocking updates. I finally got around it by shutting off my VPN and was then able to use the toolbox.
Same 403 Forbidden Error on Fire TV Max with this latest Webview update. My work around was to install Wireless File Manager & ESx File Explorer from the Amazon App Store. I had issues with the named File Explorer app paired with Wireless File Manager so I used a generic but just about any file explorer should work.
I then downloaded the APK files from TROYPOINT Toolbox to my computer, transfered them to the Fire Stick, opened/installed using File Explorer, and continued using Troypoint original instructions with router URL deny list. I loaded 3 of my 4 Fire TV Max sticks using this method with no issues.
Everything else I tried did not work including VPN off/different countries, clear cache/data, delete/reinstall from both Amazon & AFTV site, used Downloader code/TP TB site name, check Downloader version numbers against AFTV web site/onn stick Android version/other Fire TV devices, and update Webview all while restarting my Fire stick with each attempt.
Thanks to Troy for all of his instructions!
Hi, for the Nvidia Shield users you can fixed the issue by turning off ( Force to external device) in the Developers options settings.
Thank you. Yes, that is true for those who have done that but there are still many with problems who haven’t.
Before I moved forward I went into LAUNCHER MANAGER (1.1.6) and scrolled all the way down to Miscellaneous Options. Next scroll all the way down to Apps Management.
A popup WARNING click Proceed.
Scroll down and find # Amazon System Webview
com.amazon.webview.chromium and select it.
select permission and inside scroll down and look for these two select each one and grant permission and it should say success. Probably didn’t have to do the READ_EXTERNAL_STORAGE but i did it anyways.
android.permission.READ_EXTERNAL_STORAGE
android.permission.WRITE_EXTERNAL_STORAGE
once success i continued on the below.
Note this finding was random and after doing this i didnt reboot just when and confirmed in downloader at 250931 troy toolbox link works again.. This was done on my firestick 4k max with firmware 8.1.1.6. Maybe it can help others too…..
Now in FTVDB app the Amazon System Webview is showing 61212264 where before on my previous post on my 8.1.1.6 i showed an image of it being 60829632 which is older.
So i was able to fix this issue 403 forbidden by updating my firestick 4k max webview with this version of webview from APK MIRRIOR
Amazon System WebView 136.amazon-webview-v136-7103.7103.169.43 (arm64-v8a + arm-v7a) (Android 8.0+)
Under: Amazon System WebView variants Choose
(arm64-v8a + arm-v7a) (Android 8.0+)
Latest: 136.amazon-webview-v136-7103.7103.169.43 on September 5, 2025 PDT**
Download the apk and rename it to something short you can retype easy in adb shell.
Step 1 - Save it to a simple folder on your computer (e.g. C:\firestick_apk\Amazon_System_WebView_138_tv.apk. Rename it so its short when you adb cmd.
Step 2 - Connect Fire Stick via ADB
If you haven’t already
1. On your Fire Stick:
Settings → My Fire TV › Developer Options
Turn on ADB Debugging and Apps from Unknown Sources
2. On your computer, open Command Prompt or Terminal:
adb connect <your_firestick_ip>
You’ll see a popup on the TV asking to allow — choose Always Allow then OK.
Example IP: adb connect 192.168.1.45
Confirm: adb devices
It should show your Fire Stick as “device”.
Step 3 — Push the APK to Fire Stick
Option 1 — Directly install from your PC:
adb install -r C:\firestick_apk\Amazon_System_WebView_138_tv.apk
-r replaces any user-level version.
If you get “INSTALL_FAILED_ALREADY_EXISTS”, uninstall the user version first:
adb shell pm uninstall -k --user 0 com.amazon.webview.chromium
Edit update as of 2:26am 11/9/2025 Sunday
Fastest and easiest
I also used “atvtools” on my phone to connect to the fire sticks IP. Download the same file above and just hit install and takes about a min or 2 depending how fast your connection. When done just go and check downloader code 250931 and no more 403 forbidden. Works on both my 8.1.1.6 fire stick 4k max.
New 4K Max at 8.1.1.6 and this (installing the later webview) did not work.
I’ve already sideloaded launcher manager, projectivy, etc by finding direct links and installing everything, but the 403 forbidden persists trying to get to troypoint.
My PDNS is 1.1.1.1 SDNS is 8.8.8.8. Terterary IS pointed to my ISP (xfinity). All known amazon update sites are blocked in my firewall. Since I have all current firesticks OTA blocked, I suppose I could open it up and see if that changes anything?
I am having the same issue 403 forbidden. I downloaded the update you posted but still unable to get toolbox . Does anyone have a solution
Here’s what worked for me…
I went to settings>Device Preferences>Date & time>selected not to use network provided. Then I toggled back to network provided. In my case, the time zone and my ONN 4k were not in the same time zone. So I set it to the correct time zone.
Before you do the stuff that I suggested, make sure that your 4k is in your time zone. If it’s not, then just adjusting that might work.
I managed to fix it…….not sure how lol. I think enabling developer options is what I did. Watch Troypoint video for the ONN tv box. It was awesome with amazing hints.
So I just recently bought the ONN 4k Plus and I too was getting the 403 forbidden error in Downloader. VPN off. I hit home button in Downloader, then try to input the code for Troy’s toolbox again and this time it popped up. Not sure if it was the second or third attempt that went through, but it did go through to the toolbox. Not sure if it’s a glitch somewhere with the code or something else.
THIS version worked on my 4K Max 8.1.1.6. No more 403 forbidden!
FWIW, I use ADBAppControl on my PC for this and lots of other stuff like sideloading Galaxy Watches, etc. Works great if a little quirky to manage connections.

This older version did not work on Firestick 4K Max 8.1.1.6.
However, the version 136 @Rickevo9 posted in Fire TV 403 Forbidden Error in Downloader App - Shot In The Dark - #14 by Rickevo9 did work!
Maybe post up a direct downloader code to it for your followers. Cheers!
