HDX 7" - USB OTG Possible? - Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot

Is there any way to connect a hard drive to the HDX 7 (root / 3.2.4) via USB On-The-Go? Are developers working forward to it or shouldnt I expect this feature in the future?
(sorry for bad english)
best regards & thx for the help

usb otg needs to be enabled in the kernel which amazon did not enable in their builds. Because the hdx has a locked bootloader we can't do the required mods.

does anyone know how the bootloader is locked? it is encrypted or secured by some alorithm technics? it is possible to find the essential files? maybe only a structual analysis?
in my opinion it isnt impossible to crack this ****ty bootloader the way should be very hard to find.

Obviously not — everything is vulnerable.
jcase has already discovered a bootloader unlock, and it has been confirmed by some other top developers like Hashcode.
However, he has refrained from releasing it due its legality, and the fact that DCMA does not protect him with devices of this kind; i.e. tablets.
You can read more into it on this thread: http://forum.xda-developers.com/kindle-fire-hdx/general/unlocked-bootloader-im-excited-t2841202/
The only clue jcase has given us so far is that more than one of the security advisories listed on Code Aurora apply to HDX tablets.
The only problem is actually finding someone willing to test and competent enough to execute these exploits.

Now that unlocking the bootloader is possible, is there any progress on USB OTG?

I think its a matter of mussing hardware?

[Q] OTG Cable Compatability - Rookie Q.

Hello! I was redirected here from XDA Assist Forum for the following.
The device i am using is a Kindle Fire HDX 7 32GB running Thor-Gapps-13.3.2.4-v1 ROM.
I've been searching for an answer on how to get an OTG cable to work for my Kindle to play roms. I tried a much older method http://forum.xda-developers.com/show....php?t=1652800 but with no result. If there is or isn't a method please let me know :highfive: Thank you for taking a look :fingers-crossed:
Huh?
USB OTG isn't enabled on this device. I believe it is at the kernel level and since we don't yet have a released bootloader unlock, all ROMs have to use the stock Fire OS kernel.

Thank you for letting me know
Still the case? Any idea from anyone of the developers if its ever going to be a possibility? I'm about to buy another one due to its perfect physical size for my mod need and I need OTG for an FM Radio.

[Q] Some questions about my Kindle Fire HDX 7

Hi there,
I have a KFHDX 7 with Fire OS 4.5.4.
1 ) Currently, it's impossible to root with this version, right ? How downgrade ?
If it's rooted :
2 ) Is it possible to install a new rom ? like nethunter ?
3 ) We can install .apk from android store with a drag'n'drop ? (I haven't see the similare version of moon+ reader between amazon store and google store :-/ )
Thanks in advance,
Kind regards,
Sqdz'

Check this thread for downgrade info. In short you need to rollback to 3.2.8 then upgrade to 4.5.2 which can be rooted. There is risk executing this procedure including a hard brick. If you are unfamiliar with HDX devices they are exceptionally difficult to recover once hosed. Tools/techniques used on other android devices (factory cable, fastboot, usb spoofing, etc) simply don't work. You can not unlocked the bootloader on your device as Amazon has incorporated rollback protection ('efuse') that will permanently disable your device if you make the attempt.
Once on 4.5.2 You can install Safestrap v4 and then flash Nexus v4 or CM11. No other 3rd party roms are supported.
Pay attention to the warnings/cautions if you opt to rollback - especially those dealing with OTA and keeping wifi disabled. If you take an update while on 3.2.8 your device will instantly brick. At other times you will be upgraded to 4.5.4 and have to start the rollback process over again.
There are no step-by-step tutorials or helpful videos. You have to read, read, read and ask questions when needed. Do your homework before posting. If you ask a question that has been answered multiple times you probably will not get a friendly reception.

What do you think about that ?
Successfully rolled back from 4.5.4
My hdx 7 3rd gen was running 4.5.4 and was able to successfully rollback to 3.2.8 and then upgrade to 4.5.2. Next step is rooting!

Be sure to block OTA. An update will push you to 4.5.4 and kill root.

What's the procedure for this downgrade ? We can change the rom ? (like nethunter). Or I can return my kindle hdx for a nexus 7 2013.

Dude - just get a Nexus 7. Easy to root/unlock and supports tons of third party roms. HDX has better HW but is a royal pain to mod and does not support your preferred rom.

KingRoot is the best option assuming device is running FireOS v4 (post back if on v3; there's an easier method). Multiple attempts may be required along with a factory reset. KingRoot is unsophisticated beast that often reports failure when a root exploit is known to exist. If you opt to reset do not register device with Amazon during initilization as it can reduce the odds of a successful root.
If you aiming to install the Play Store be aware it will not work (well) as Google Play Services/Frwmework and FireOS v4 do not cooperate. You will need to unlock the bootloader and install a custom ROM first. Details here.
Be prepared for some long reads/nights and frustrating misfires. This is an aging device with limited support. Ask targeted questions as needed (might not get an immediate response). Don't expect hand holding or a scripted tutorial. If new to rooting and/or tethered operations you should probably consider another device.
What is the best custom rom for the Kindle Fire HDX 7 in your opinion? I am going to root mine which I know how to do already and I am just wondering what is the smoothest running for the HDX 7.

I believe your device is currently running a KitKat build of Fire Nexus. Doesn't get much smoother than that. However, if you desire a more contemporary UI any of the Nougat builds should work fine. I'm partial to LineageOS but don't interpret that as a ding against the others. Note: you will need to unlock the bootloader to use any of the Nougat based ROMs; root is not sufficient. Also note Fire Nexus is already rooted.
I am referring to my other Kindle Fire HDX 7 that has never been rooted. I have two they are my kids' kindles. The one that you helped me fix is running Thor. The other that I am considering rooting is running the latest update to the Kindle Fire OS for the HDX 7 which is 4.5.5.1. My son wants Google play on it but I was able to add a bunch of his favorite apps from Google Play onto it using Dropbox and transfering the APKs from his phone to his kindle with Astro and all the apps we transferred worked except Mario Run which requires Google Play Services. If I can keep him happy with it the way it is I am not going to root it but if I decide to I was just curious which was the most preferred.
I appreciate all your help!! You help all us noobs on this site for nothing and use your free time to answer our questions even when some of them are especially annoying or redundant and I am sure not just me but all of us on the forum really appreciates what you do!! YOU ROCK!! :good:

Thanks for the kind works. I am a big fan of "if it ain't broke don't fix it". Queue collective gasp from die-hard tinkerers. If you son can get by with his device the way it is leave it alone. You'll both be happier for it.

TWRP and Root?

What are the chances that this device will get TWRP and Root?
Not that I know... But this seems to be the best android tablet around now considering the price. Furthermore, its born with Android 8, which means it will be treple enabled thus the adaption of vanilla Android or others should be easier. Likewise, this should also improve security patches. I hope that someone will bring it.
Any progress of Rooting the HUAWEI MediaPad M5?
I want to buy it cuz my old Pixel C is sadly broken, but I wanna wait till it gots Root and Custom ROM:
@Marcopoloy13 I am in a similar situation as I would like to retire my old Nexus 7 (2012) and I am quite optimistic that TWRP will be available quite soon, as there is a device tree for the Honor 9 available and the Mediapad M5 sports the same SoC ...
As I am receiving my Huawei Mediapad M5 PRO next week, I wanted to look for root ... Is Huawei known to make a fuzz about root in case of sending it in for repairs etc. (I have a Samsung-past, friends of mine had issues with their support due to root ... ) ?
I am very new to Rooting, i just want to get linux deploy on this tab to install Debian. I have unlocked the bootloader the rooting is very hard.... i have no clue to what i am doing and was following the guide on this awesome forum but the imaging and so forth is not somthing i understand.
i have the CMR-w09 (non pro)
Unlock the bootloader?
How did you unlock the bootloader? I tried the “Huawei unlocking page" mentioned at Kingoapps website, but it didn't find anything about unlocking or bootloaders.

For any WIFI only device, contact Huwaei via Phone (they rarely answer mails, so dont write one), explain the problem using their site (WIFI only device, therefore no IMEI etc), provide them your tablets serial number and let them send the unlock code via mail to you. Takes usually two business days until you have the unlock code.

HDX gpu drivers and android 6 ROMs

Hello,
I'm new here and I'd like to clarify one thing. I'd love to ditch the official os. The thing is, I've read somewhere that android 7 doesn't support andreno 330 due to lack of hardware support for openGL es 3.1. So I'd like to know if it's the same for Android 6? Will my gpu function properly? I just want to turn my hdx 7 into android tablet. I don't mind some minor glitches with bluetooth, etc, but I need to be able to install gp store and have the gpu work properly.

Don't know what you read but it doesn't apply to this device as Android 7.1 is the primary custom ROM (4 variants). There is some prep involved before you can go that route including unlocking the bootloader. Got access to a Linux or OS X (Mac) environment? You can also unlock with a Windows host but the ride is none too fun.

I've jus rooted my Thor 4.5.5.3. Yes, I have access to Mac running high sierra. I want to use this ROM, as it says the gpu's working:
https://forum.xda-developers.com/ki...ment/rom-cm-13-kindle-hdx-2015-11-29-t3259732
I was reading this:
https://forum.xda-developers.com/kindle-fire-hdx/general/thor-4-5-5-2-easy-to-root-unlock-t3571240
So that one click unlock bootloader is the best way? Once I get it unlocked, can I flash a new ROM with twrp? I'm trying to find appropriate guide.

As previously stated integrated GPU works fine with all contemporary Android 7.1 based ROMs for this device. This can be observed with varying loads via any well regarded kernel manager. In my experience the default msm_adrino_tz governor works best. Not that it matters much. 330 is ridiculously weak. Don't be that outlier that tilts to some obscure writing ("read somewhere") that has no basis in reality. Android 7.1 could care less about the underlying hardware as kernel handles the interfaces.
See this thread for info on unlocking the bootloader. You will need to PM the author for a copy of the appropriate scripts. There is a manual method (what I always use) but 1-click makes the process much easier...especially for those unfamiliar with this device which ain't your typical Android gizmo. Good luck.
