[Q] Kindle Fire HD - Lost Root After 7.4.6 to 7.4.8 Update - Any Advice?

cautiousone · Feb 21, 2014

Ok, so I'm a noob when it comes to this stuff, but I have managed to root my Kindle Fire HD 7" and I installed the Google play store, so I was happy thus far. Yesterday I lost root and couldn't figure out why. Today I noticed that my Kindle had done an update from 7.4.6 to 7.4.8 and I'm wondering if this is why I lost root? If so, how can I fix this to get my Kindle back into root? Like I said, I'm a noob and don't want to screw up my Kindle messing around with stuff when I don't have a clue. Any advice would be of great help, thanks in advance.

Oh yeah, I should add this information: I get this pop up from Superuser, "There is no SU binary installed and Superuser can not install it. This is a problem"

Yea when it updates it clears the system partition where the su binary is stored, you need to reroot it. Never heard of a 7.4.8 update, but if it is a new one and you can reroot it then you can just downgrade it with kindle fire first aid by sticking it into fastboot with a simple "adb reboot bootloader", think kffa will do it for you though.

" Never heard of a 7.4.8 update, but if it is a new one and you can reroot it " Hmmmm, the way you worded that makes me feel like I might be stepping into uncharted territory if I try to root it again and I don't like the thought of that. I'll think about it and maybe give it a try tomorrow after I get some sleep and my head is clear. Thanks for the advice, I really appreciate it.

I had the same problem starting yesterday. My Kindle upgraded to 7.4.8 and any app requiring root stopped working, namely Google Play Store, SuperUser, ... I used KFFirstAide to re-root the Kindle and all is working so far.

:good: Awesome, thanks for passing that on to me, I'm going to give it a go and see what happens. I'll post a status update later today after I've had a chance to thoroughly test it.

cautiousone · Feb 21, 2014

:victory: Well I got it to root again and reinstalled google play with no issues to report, all went well. So is there a way to stop Amazon from updating my Kindle in the future? Now, the next task is to get a second boot loader on it, although I don't have a fastboot cable, so I'm kinda chicken, hahaha. But I'm feeling confident now, so maybe I'll give it a shot tonight. Wish me luck... A big thanks for the help, I guess I just needed some reassurance on re-rooting the thing and I'm happy.

Just make sure you downgrade the bootloader first, if you don't use the fireflash method then I recommend making sure to check the md5sum of the bootloader before downgrading it so you don't end up with a paperweight.

I'm having this issue also. Same update, same loss of SU + Play store.
I can't get my kindle to root like before though. It says it was successful but my fire becomes extremely laggy, no icons appear, where the navigation swipe is there are slightly darker vertical lines and the only way I've fixed it is by factory restore.

How are you rerooting???

I can't remember how I rooted in the first place, I only remember that I had massive issues getting GP store on and used this KFFA which is what I'm now using to reroot.

I just followed the same steps as I did the first time I rooted it, I used KFFA. But this time around some of the actions described didn't happen, like Superuser didn't ask for permission as it did the first go around and a few other little things, but I just took it slow and easy and it came out working fine. Also I used KFFA to install GP, it also skipped a few actions, but I just have it a little extra time to do its thing and it works perfectly. I saw a fix for the laggy screen and icons issue somewhere, I think it's in KFFA? I would have to double check that when I get home to be certain.

Thanks for the heads up on that, I've held off on doing it until I have more time to research it. I like to feel somewhat comfortable going into it and not totally freaked out. Thanks again, you guys are great around here.

dEADwEIRD · Feb 22, 2014

Sorted.
I rooted using The Bin4ry Method and using KFFA to bring all the other systems back on line.

gregcavaretta · Feb 22, 2014

is anyone having problems with ADB and fastboot on 7.4.8?

Because I tried rooting using KFFA that didn't work I kept getting errors so I tried using fastboot to flash the recovery using this code

Code:

fastboot flash recovery recovery.img

I get "device not found" or when it dose work i get "failed to flash" (something like that) but i have the adb drivers installed would there be different ones for 7.4.8? When I type

Code:

fastboot device

it finds the device it just dosn't work when I want to flash

and only half the adb commands work

stunts513 · Feb 23, 2014

You have to have it with a special parameter telling it what the kindles vendor id is so it should look like this...:

Code:

fastboot -i 0x1949 flash recovery recovery.IMG

Try that.

"... I used KFFirstAide to re-root the Kindle and all is working so far."

I tried using bin4ry's root, which is how I originally rooted my kindle, but it did not work.
I am pleased to say that KFFirstAide was able to restore root.

Thank you xda for pointing me in the right direction!
