Bricked Fire Phone after unroot.

[ekztal]

While trying to get Android Pay to work I removed root from my phone using the option in Kingroot's menu and then restarted. Now FireOS doesn't load and doing a factory restart from recovery doesn't do anything either.

I thought I'd just sideload 4.6.3 and restart from scratch, but when I connect my phone in 'sideload from adb' mode from recovery I only get a "Fire" device in device manager. After a minute it gets an error "Device Cannot Start"

Manaully scanning for hardware changes doesn't give me my "Android Composite Device ADB Interface"

Sounds like you don't have the ADB drivers installed correctly. See this post:

Thank You. That's exactly what was wrong.

I didn't think was would be the problem since I had used that 15 second adb installer last night to get adb working before I messed everything up this morning.

In recovery mode I'm sure it connected to my computer as a different device!

Thanks again.

No problem. Glad it worked out.

The problem could be the filename. Microsoft Edge and Internet Explorer download the 4.6.3 update as a .zip file. If your folder options are not set to display all files extensions, go to Veiw> Options> Change folder and search options> View>. Uncheck "Hide extensions for known file types" and click OK. Check the filename for update.bin, if the filename is update.bin.zip, changing it to update.bin should correct your problem.

If the fielname is correct, the file path could be the problem. Try entering the complete path to the file, use quotes around the file path if there are any spaces in the file path (for me the file path is: "C:\Program Files (x86)\Minimal ADB and Fastboot\update.bin").

If you still can't install the update, then see Problem with "cannot read update.bin" in 4.6.4 to 4.6.3 downgrade on how to use Safestrap to install update 4.6.3.

Hi
Even my phone is bricked but when I try to sideload update.bin , cmd prompt throwing error as " cannot update.bin". My fire phone is identified by windows 10 with adb drivers.
Can someone suggest how can we fix this issue?

Thanks

Thanks, I will try what you had suggested on windows 10 but I can not use safestrap as except " amzon" logo I can not see anything after power on so I am getting to apply update from ADB using buttons. So how can I install safestrap and king root without turning on browser on mobile.

Thanks

You won't be able to install Safestrap or Kingroot unless you can bootup your Fire Phone, so sideloading the update is your only option. It appears that your ADB drivers are installed correctly, just to be sure, see DePingus's post.

Thanks, it worked. My fire phone is up.

Hi a little help if you will please.

I've rooted then installed safestrap. Done back up, factory reset then Flashed c11 rom. All looked great. Made up with the ROM but I've tried to use kingroot to root again but it won't work. I can get in to safestrap recovery but says it's inactive. I've tried to search for the fix but can't find anything directly for my problem just how to root with kingroot. Any help would be great. Thanks.

Can't unbrick it.... tried everything

Hi guys, I installed CyanogenMod on my fire phone and it worked for a while... then started rebooting, but before I could do anything it was just rebooting all the time, then I did a hard reset on fire phone and after that... only adb sideload, safestrap was gone... but... adb works fine, everything gets installed, but after rebooting amazon fire phone is lost in a endless rebooting cycle (just shows up the amaozn logo... if powered via USB it tries to do something else, amazon logo shows up for maybe 2-3s longer....

Boys... did I brick my phone forever? Thanks
