[Fire HD 6 and 7 Android Development] CandyAngel:
The replacement battery arrived today and when I plugged it in, I saw (some sort of) recovery screen come up! .. for about 5 seconds, and then the device rebooted. Looks like it isn't a battery issue after all :(

Not sure what else I can do now. I found that someone had identified the TX on the JDEBUG pins so I might try connecting that up and seeing if I see any output.

Any other avenues I could explore to get this Kindle running again?

EDIT: If I boot it with the original battery, there is a warning at the bottom of this recovery screen stating the battery level is too low. This doesn't show up with the new battery. The menu is also responsive (can scroll through it with the volume keys) but I'm unable to do anything due to it rebooting.

EDIT #2: For reference, battery voltages are 3.4v (original) and 3.9v (new).

Mine bricked by flashing latest Fire os

Hi, I have my Fire hd 6 and I've been following the steps inn this thread https://xdaforums.com/fire-hd/general/2017-root-kindle-fire-hd-6-4th-gen-t3677600 going fine until I did the step #20. That bricked my device.

Maybe because the link in the fire os is the latest 5.6.1.0 instead of Fire OS 5.4.0.0.

My Question is what method/tutorial did you follow to unbrick yours?

I got stuck at the linux os tut. The ./reader.sh doesn't give a response. :confused:

Can anyone help me? :rolleyes:

Replies are much appreciated! :D

Feedback on kindle fire HD 6.

I will briefly describe what I went through and some minor changes I had to make. I Completely wiped my Kindle Fire HD 6 from within TWRP and got it working again.

1. Installed Fire OS 5.3.x, Hated it lots because of battery drain, so I wanted to downgrade.

2. During the downgrade process (4.5.3, I installed KingRoot (not knowing what it was). This caused system stability issues and permission issues that it would refuse to let go of even after factory reset and adb forced restore.

3. I was able to install some apps, but the icons were missing, so I wanted to do a fresh reinstall. I ended up wiping the entire system, OS, files, everything. This lead to a bootless device.

4. I followed this guide on Youtube with some modifications:

1) I used parallels on my Mac to install Linux and did that process. When I ran ./complete.sh with my volume up held, my fire entered into a rebooting loop. I unplugged it and got it to boot into TWRP somehow (using the buttons).

2) The Fire OS provided (5.3.1) would not install, it gave me an error. SO, I used Kindle fire OS 5.3.1.1 Found Here:

3) I installed the uboot, recovery, and 5.3.1.1. OS.

I am not sure if I should go back to 4.5.3, because apps would fail to install from the Amazon store previously. However, it was more selective long before I upgraded to 5.3 The reason I upgraded was to use Google services somehow but that didn't work either.

Thanks for the awesome support!!! :D:D

I have the same issue

[Fire HD 6 and 7 Android Development] Ender875:
I think I had the same problem. Mine would be recognized in device manager for a sec then disappear, then be recognized, then disappear, etc.....

I did what DimonX did in his post a few pages back:

"Also, I hung my balls to the wall and flash the newer 5.5.2_1534_stock_recovery_uboot.zip.

It's works!

After unbrick I installed update-kindle-20.5.5.2_user_552153420.bin + 5.5.2_1534_stock_recovery_uboot.zip and SuperSU. Everithing is good! [MENTION=1449759]DimonX[/MENTION].

[Fire HD 6 and 7 Android Development] Vcy:
Hi guys does this method apply to me if I can still get into recovery mode? My device is stuck at the "fire" screen and I believe it should be on the latest OS.

I ask because I looked around and read that it may just be softbricked.

Edit:

Downloaded the OS, applied it via adb and everything seems fine now.

So, I dug out my old 7" Fire HD and it's only booting to the "Amazon" logo, sitting there for a bit, then rebooting back to the "Amazon" logo. I tried to use the Linux distro for this, but it doesn't seem to work for this issue, it never would handshake, I don't think it was having enough time before rebooting again. figured I'd share in case someone else is trying to use this software for a similar issue.

Hi all,

Awesome work putting this together powerpoint45 and bibikalka!

I am trying to recover my bricked kindle (see thread here: https://xdaforums.com/fire-hd/help/help-bricked-fire-hd-4th-gen-t4003681) I can get the handshake.py working, but the script reader.sh just hangs, showing a blinking prompt. Any tips or suggestions?

[Fire HD 6 and 7 Android Development] M03:
Thank you, worked on my HD6 (No brick, I just misflashed a wrong verison of twrp and i couldn't access recovery but the tablet was working quite fine).

Anyhow, after following the steps you provided I was able to get into recovery and I have downgraded to 4.5.3 and now I'm on Lineage OS 11 with TWRP 3.0.2..

I have a question though.. can I install the latest Fire OS 5.3.6.2 using my current TWRP 3.0.2 without affecting the recovery image? or will this cause a brick?

Edit: so i decided to return back to stock FROM

4.5.3 into the latest Amazon FireOS which is 5.3.6.2 with TWRP 3.0.2

BUT i ended up with a bricked tablet and it is now unusable.

this is where the ./reader.sh started to hang although earlier with my previous attempt it worked just fine. This seems a bootloader issue and the script is simply unable to communicate properly on the tty port although it's being captured aka the handshake of the "bootloader boot up"

So for whomever reading this and wonders if he/she can simply flash the latest FireOS on top of the old bootloader with a TWRP recovery,

YOU WILL END UP WITH AN UNUSABLE DEVICE

Welp, this is a super long shot.

Got a Kindle Fire HD 8 from a friend (5th gen, KFMEWI I want to say...not 100% certain) that was bricked awhile ago.

Specifically, it's stuck in the black screen and loads/unloads the MT65xx preloader when plugged into a PC.

I admit, I really thought I could get it to connect via adb. No dice.

But after searching for the preloader issue, I was able to complete the handshake and reader scripts using this fantastic ISO. That gave me some hope, although I realize this is meant for the HD6/7.

...but the determineOption script gave no results. I suspect that amounts to the differences between the HD6/7/8.

That being said, there was a bit of hex code under "Option B" in the response from that script, where A and C had nothing.

I've got the .part files, but at this point I'm out of my depth.

I was going to try the option B unbrick, since the worst that can happen is it remains bricked...but I thought I might as well reach out and see if anyone has some additional direction.

So, do I have any hope here, or is this thing a paperweight?

.part files attached (with any luck), and also here just in case: gofile. io/ d/ 2bbo46

Thank you I now have a working Fire HD 7 again.

I followed all the steps as outlined by powerpoint45 and his amazing Linux Disto and Youtube Video

I could get into TWRP and see the device on my Windows 10 PC but after re-boot got stuck on a black screen always. I knew the device was not dead as I could here life on the USB port. After running through the whole setup several times and always getting to TWRP I read carderel's post and decided to side load instead of using install in TWRP both the stock recovery in this post and the latest Kindle Update 20.6.0.5_user_605487420 which I downloaded direct from Amazon and then reboot the tablet, fist a blank screen then it auto rebooted again and amazingly the Amazon Logo appeared and then after a short wait Fire it came back to life. (At this point I was not bothered about totally bricking the device it has been in a draw for a year and using the Fire interface. I was just happy to see it working again and my nephew can get some use out of it watching Peppa Pig :-) ) Thank you for all the great post.

Hello fellas, I know that theres a lot of another topics about this subject. But I see each of this and dont found a solution.

Whats happen is that I accessed the menu *#2663# and I clicked in Touch Key FW update. After this, no more touch works.

I tried a custom rom (Cyanogem 10, 13, Albe95,Ressurection)

I tried a stock rom (last rom, fist rom with android 4, using .pit files, using ap, bl, cp, csc files)

I tried wipe data factory

I tried wipe cache

I tried wipe dalvik

and nothing works! my buttons back and menu work but my touch not work! :(

I suspect that my firmware touch is corrupted. I don't know.. There's a way to restore this?

I'm a brazilian developer (c# , desktop and webapp) and i follow xda a long time... I used any other rons with my old devices (Milestone, defy)... but this time I don't know that I can do.

GALAXY TAB S2 - 6.0.1 STOCK ROOTED ROM

​

You need to have a custom recovery installed on your device before flashing this ROM

!

This ROM was designed for daily use and has been optimized to allow users to uninstall most apps which were previously locked into system memory. This means more control over your tablet and more available memory should you want or need it.

Big thanks to Superr, ashyx, and pvsgh!

DOWNLOAD - ODEXED VERSION

HOW TO INSTALL

:

-Copy .zip file to your SD Card

-Power off your tablet

-Reboot into Recovery Mode by pressing [Power + Volume Up + Home]

-Install the .zip / reboot when completed

If you appreciate my work and would like to buy me a drink, you may donate at the link below. Thanks are always appreciated!

[Galaxy Tab S2 Android Development] chris1683:
I would suggest wiping cache, data, and dalvik prior to installing to clear any previous files. Bear in mind that when you see the Samsung logo it is installing the system files behind the scenes. It typically takes about 5 minutes before you get to the welcome set up screen. Please also confirm this is for your device T810 with Exynos processor.

I have not encountered any bugs. This is based off of bone stock and includes all of the originally included apps but now allows you to de-bloat the rom yourself and uninstall incessant apps. I welcome you to post any finding you encounter while using the rom. Enjoy!

I started using this rom a few days ago (the easy-to-flash rooted stock is very nice). But I've noticed that now I have to reenter the password every time I connect to a network. I'm hoping not to have to do a factory reset to get the tablet to start remembering networks again.

I hate to leave things hanging, and I especially hate to cast doubt on a great ROM.

It's been ages, but I think I finally discovered the answer on another forum. The ROM was not the problem :)

The problem happened after I flashed several ROMs and other files repeatedly trying to find a way to hide root on my T810. I think that somehow the ownership of wpa_supplicant.conf got messed up. This appears to be working:

Enter the following commands in terminal (the place I found this said to use ADB, but the terminal in TWRP worked for me).

# cd /data/misc/wifi
# chown system.wifi wpa_supplicant.conf
# reboot

[Nexus 6P Q&A, Help & Troubleshooting] adararnon:
Hi,

I have a Nexus 6P (as you could guess) runner Nougat, and for some reason my phone doesn't get the monthly security OTAs.

When Nougat was officially released, I waited a free days, and after getting tired of clicking the "check for updates" button, I sideloaded the image zip through ADB.

My phone used to be rooted, but I reverted everything and locked the bootloader.

A few days after the September update was released my phone didn't get it, so I sideloaded it too. Now the same thing is happening with the October update.

One of the reasons I unrooted my phone is so I don't have to manually update the phone every month, so it's quite annoying.

Has anyone experienced this? My first guess would be that Google is doing a staged rollout, but we're talking security updates here. That would mean they're willfully exposing you to 1-day vulnerabilities.

P.S. my phone is not a carrier phone
