there is no button combination, for adb

but it is not possible that adb is available during part of the boot, unlikely though

Power off then power on

try

adb reboot recovery

i am sorry i meant to ask a different question, is there a way to get to stock recovery mode in 5.1.1 when flashfire is used?
[Fire General] sd_shadow:
what likely happened is FlashFire moved the wipe option to last task

so the rom was wiped from system, then device rebooted

for some reason those with the 5.1.1 bootloader, lose recovery, for some reason.

if the rom was Bootable, i believe stock recovery would also still work.

right now I have no idea how to fix it.

[Fire General] sd_shadow:
Factory/Fastboot cables do not work with 5th Gen

I'm thinking that downgrade failed due to

bad firmware download (incomplete download, or wrong file), bad connection (pc, usb, or Fire), some kind of hardware failure on the Fire, or some other issue.

I've added checksums to the Index, and added instructions on how to use checksums to this thread

Unable to root Fire

I just got my hands on a new Fire tablet, and have been attempting to it. I downgraded the firmware to 5.1.2 instead of 5.1.4, but Kingsroot still fails around the 19-21% mark; I've reset multiple times and the furthest I've reached is 25%.

Again, everything is just fine until the 19% mark ; sometimes it reboots first, sometimes not, but immediately after I will fail out and it will restart. Driving me nuts, so any help would be welcome! :eek:
[Fire General] DB126:
Reload 5.1.2 again but don't register the device with Amazon on restart. For whatever reason that seems to improve Kingroot outcomes.

Understood. But I would think that as test commands go, it is helpful in illustrating why I can't sideload, no?

WARNING: downgrade from 5.1.3 using this process bricked my device

The above is not correct for 5.1.3 devices. I bought a new kindle fire 7" 5th gen device on Prime Day that came with 5.1.3 installed. There were no errors or warning displayed when I side-loaded the 5.1.2 update, but on reboot the device was bricked.

The file I used was update-kindle-37.5.2.2_user_522054520.bin - stay away from this file if you have 5.1.3.

I have tried to unbrick using the pythons serial tools process by hwmod, but no joy. If anyone else has found a way to recover from this I would be grateful for any tips or pointers.
[Fire General] sd_shadow:
many have downgraded 5.1.3, without issue
[Fire General] sd_shadow:
yes that is the 5.0.1 firmware, it will brick any device over 5.0.1
[Fire General] sd_shadow:

update-kindle-global-37.5.4.2_user_542168620.bin
[Fire General] DB126:
Sorry for your experience. There is nothing wrong with the guidance. As previously noted many have followed this path without incident.

Did you verify the checksum (MD5) after downloading 5.1.2? A corrupt img/zip will trash a device quicker than you can say 'brick'. Although unlikely a glitch in the data transfer can yield similar outcomes. A poor USB connection or sketchy cables can manifest into an uncaptured fault.
[Fire General] fmc000:
He used the wrong file... His device is gone.
[Fire General] DB126:
Yep, saw that immediately after posting my response. It's a shame that a simple mistake has such consequences (thanks, Amazon) but also speaks to a common mindset that assumes the community is in error when something goes wrong. One data point does not tell all.
[Fire General] Dunard:
Amazon need to remove the rooting blocking from their devises. People gonna keep trying to root their devises. Sending those devises back to them and then wasting their own money by sending a replacement. lol

I wonder there a program hidden somewhere to block KingRoot and many others.
[Fire General] fmc000:
Indeed but flashing a ROM is not something that everyone is supposed to do. The minimum you must do is paying attention and double-check everything before you start.

You cannot just say "it doesn't work" when it's written "you can downgrade from 5.1.3 only to 5.1.2" and then you use 5.0.1 ...

---------- Post added at 05:53 PM ---------- Previous post was at 05:49 PM ----------

Amazon can do what they wish on their devices. And there's nothing that blocks KingRoot of other programs: they exploit bugs that allow privilege escalations. Google and others do their best to fix those bugs, eventually other bugs show up and the root enablers try to exploit them.

Actually, it's really possible that the difference between 5.1.2 and 5.1.2.1 is just the fix for the privilege escalation bug that allows the first firmware to be rooted.
[Fire General] specialtydrone:
Hey all. First of all, thanks for all the hard work on Fire devices.

I'm trying to downgrade from 5.1.4 to 5.1.2. The MD5 is verified for my downloaded firmware, but I'm getting "failed to verify whole-file signature" errors during sideload. I've tried the process on two different Win 10 machines with no luck, and going to try a third shortly. Is there anything else I could be doing to get around these signature failures?

Edit: Har har, was trying to use HD 7 firmware file instead of 8. Idiotic. I'll report my findings here when I finish trying to load the right firmware file.

Hey guys

I have a little issue that I do not know how to resolve.

I was messing with my tablet using flash fire. I installed SlimLP and I guess I was trying to install TWRP and somehow deleted the stock recovery.

Everything was OK until something made it crash and now reboots everytime. So, if I turn it on, it boots all the way to the home screen, but seconds after reboots itself.

I was looking for a safe boot mode, but did not find anything. I was then going to try to clean cache or reinstall the rom, but I have no recovery to boot into. If I try to boot into recovery, the tablet just hangs in the Amazon logo forever, but I can boot into fastboot.

I was messing with rootjunkys supertool, but nothing seems to work.

I also tried installing TWRP in fastboot, but get a message saying that Remote Flashing not Allowed.

Any help? Thanks

Edit: I got it to boot into safe mode, but it still reboots .
[Fire General] sd_shadow:

[Fire General] Parhelius:
I apologise in advance for what may be a very stupid question, but hopefully my lack of knowledge with rooting/android systems will be apparent here.

I'm running CM12.1, my fire shipped on 5.0.1. and I rooted before it had a chance to upgrade. I'm interested in using other roms, and from what I can see in this thread, it should be possible to revert to stock and then flash a different rom. However, my computer won't recognise the tablet (I get error messages in device manage that the usb connection has malfunctioned, but this only occurs with the tablet). Otherwise, the tablet works fine on CM12.1.

It is possible to put a stock rom file (i.e .bin or .zip) on the SD card, boot into recovery and somehow install the stock rom from there (using the "apply update from external storage" option or something)?

Again, sorry for my naivety, but I've been digging around and experimenting for a few days now, and I can't find anything to help me get around this.
[Fire General] DB126:
You can use FlashFire (0.51 or better) to go directly to another rom; no need to reload FireOS first. That said, I would give careful consideration to making any changes if you can not access stock recovery and establish a stable USB connection. Sideloading FireOS is often the only recovery method should something go wrong which is not all that uncommon with FlashFire, especially when switching roms. At present FireOS can not be reloaded from internal storage, OTG dongle or a SD card.

How about a guide that summarizes the latest knowledge?

As a very senior member -- of the human species, that is, I'd really appreciate a post in the form of a guide that is regularly edited with the latest information in the first or second post of the thread. My ability to concentrate and follow a long thread has deteriorated in the 4 years since I first joined this site, and even then it was a chore to extract the needed info from a thread with tens or even over 100 posts. And I'm sure there are readers who are young enough to be my grandchildren who would appreciate a summarized presentation of the information in a thread like this.

So, although nobody is obliged to do the work to make things easier for the rest of us, I'm putting this out there with some hope that somebody will, and not just for this precise topic!

BTW, I bought one of these from Amazon on sale for $35+tax, but even at that price I'm thinking of returning it (I haven't opened it yet!) if I can't use it with most android apps, including Chrome and other google stuff.
[Fire General] DB126:
Appreciate the post. Reality is the effort to maintain what's there today, including a comprehensive forum index and dozens of related posts by [MENTION=4267571]sd_shadow[/MENTION] is enormous given the shifting landscape and wide range of expectations, not to mention experience/skills, of the reader base.

As for your device the ability to root and (if desired) install custom roms is entirely dependent on the version of FireOS currently installed. You'll have to open it to find out and keep it off WiFi to avoid an OTA update from Amazon that could ruin your day. If that feels complicated or burdensome you should probably return it and look for another device that comes with the Play Store preinstalled.
[Fire General] sd_shadow:
what information were you looking for?
[Fire General] aarons510:
What information ...?

Basically, I want to have an overview of the possibilities and pitfalls of trying to use this as an android tablet, with or without replacing the ROM. That includes having a reasonable idea of what I'd have to do to accomplish that without wading through hundreds of comments. Even though I like the idea of getting a nice tablet for the $35+tax I paid on sale, it's not a real saving if I have to spend many hours to get it to a reasonable satisfactory operating state, with the risk of ruining it altogether. I do also have a bunch of older tablets and phones that I have worked on or could be working on, including KF otter, KF otter2, original Nook Color, and a Samsung Galaxy Note 10.1, so the only advantage of this KF 5th generation tablet would be its newer hardware. (The more I think about it, the more I'm inclined to return it, even though I have this neurosis about not passing up a bargain.)

I do think, though, that it is a good idea to have information like that in this thread in the form of a guide or wiki, with all the verified info, and unresolved questions, in one place.

[Added:] I decided to open the box and check out the new Fire tablet. It turns out that it has version 5.1.1 of the OS, which, if I understand correctly, is a lot better for purposes of customizing than are the later versions. To be as secure as possible against OTA updates, I turned off wi-fi, turned on airplane mode, and am keeping the tablet away from any open wi-fi hotspots. When I get ready to deal with using and modding it, I will look at other threads than this one, but thanks to those who responded to me here.

If you unwittingly attempted a downgrade from 5.3.x then it's a brick. If within warranty contact Amazon for an exchange.
[Fire General] aarons510:
I don't remember, if I ever knew, much about Maslow and his Hierarchy of Needs, since anything I read about him or by him would have been at least 30 years ago, and maybe even close to 60 years ago, when I was into reading a lot about psychology. But I certainly agree that none of the 'needs' any of us write about here come close to the seriousness of the very real, and barely met, survival needs of hundreds of millions of people on our planet, and the very real, if somewhat less critical, needs of a few billion more. So if anybody here can figure out how to use their skills to help meet those needs, including the need, or at least desire, for overall human survival, I certainly encourage such people to spend less time on this forum and more time doing those other things.

But I do think that if people are going to put time and energy into posting here, it's worth some collective effort to organize the information in an accessible manner, so that those trying to access the information will have to spend a lot less time, and suffer less frustration, trying to find it.
[Fire General] sd_shadow:
I have created Index, FAQs, and Help threads, look in the in Index, and FAQs.

If you cannot find what you are looking for ask in the Help thread.

If you find something you think should be in the Index or FAQs, post a link to where you have found the info, or write something up yourself.

I have been on this site (as a member), about 5 years, following ~13 devices that I have used, plus several that I am just interested in.

I have seen countless complains about lack of info, but those same people rarely contribute.

Just that they had to search for days to find what they wanted, with no real details as to what they were looking for, nor what they found.
[Fire General] aarons510:
Even as recently as four years ago, I was able to make small positive contributions to discussions on this site, and I'm hoping that, if I can conquer my insomnia, my aging brain will again be able to do so. In the meantime, I'm frustrated but I still appreciate the efforts of people like you, even if you don't, and maybe can't, present information in a way I that I find easy to follow.
