Yes - you will need to reenable OTA for the update bin to be process. Be sure to disable WiFi first and keep it OFF until 4.5.2 is installed and OTA reblocked. For an added layer of protection enable airplane/flight mode. As you are probably aware receiving an OTA update while on 3.2.8 is fatal (unrecoverable brick).

Other thoughts:

- after rebooting it may take 10-15 min to recognize the update file

- if still no luck (after enabling OTA) verify you have a good file. MD5=0371E50D222048D329BDAA3F12FE66BD You can sideload ES File Explorer via 'adb install <apk>' if needed to check the hash

Post back if still having problems.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] Stetanchi:
Hi Guys,

thanks for responses.

I reenabled OTA using HDX Toolkit, checked the MD5 checksum which is fine.

But still not able to update with WIFI enabled or disabled.

When clicking on check updates the device states "Last update failed".

I guess this might be related to the fact that I let Amazon rollback the device in early 2015 hoping to get a version where I can unlook the bootloader. But Amazon was only able to rollback to 13.3.2.8.

What I have read somewhere is that an Amazon rollbacked device will not update after the rollback in any case.

Any other idea? Do a factory reset, if that helps at all.

Is there another possibility to update the device, maybe using ADB?

Thanks, Stefan.

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
An amazon initiated rollback to 3.2.8 does not disqualify your device for subsequent manual upgrades. The OTA update block is imposed on the Amazon side.

Further suggestions:

- re-enable the OTA block, reboot, disable, reboot, wait 10 min, look for updates (I expect this to fail but worth a try).

- perform a factory reset from the native recovery menu accessible via <power>+<vol-up> from a cold start. Note there is some risk in doing this as devices occasionally fail to restart after a factory reset. Make sure you are rooted and USB Debug enabled in FireOS before taking this step. Skip WiFi set-up when your device restarts then disable WiFi (and/or enable airplane mode) at your earliest opportunity. Verify the 4.5.2 update file remains in the root of sdcard and try again.

- contact Amazon, explain the situation (you want to upgrade to FireOS v4) and see if they are willing to lift the OTA block. Make sure the representative is willing to make an adjustment (in the form of a replacement device vs a $20 credit) if the update goes bad. If all goes well you will eventually land on 4.5.5 which can be subsequently rolled back to 4.5.2 which is required for Safestrap. Note this approach entails risk both from Amazon's actions and those you must subsequently perform to rollback/upgrade.

Hi, Help - HDX7 THOR upgraded to Nexus ROM but...

NM - it sorted itself. First boot took FOREVER :)
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] zx2gsxr:
Yes, thanks. I needed to wait about 38 minutes for the initial boot to complete. ISTR a similar experience upgrading my HTC One M7 about a year ago, too.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Performing a factory reset from within Safestrap (NOT the native HDX recovery menu) after flashing a ROM typically avoids this behavior. Or wipe cache and dalvik if you want to retain personal apps/data (ie: dirty flash). Same guidance applies for native twrp and other tools like FlashFire. Wiping caches prevents a lot of start-up weirdness and has no side effects other than a slightly longer initial boot.

BTW - what looks like twrp from within Safestrap v4 is not the real deal. They behave similarly but are not identical. In particular Safestrap can not be used to recovery a device that won't boot. Best to call it just Safestrap so there is no confusion (unless you are one of the lucky few with an unlocked bootloader and the real twrp).

Hi Davey, I will give it a try and let you know.

BR, Stefan
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] Stetanchi:
Hi Davey,

I did what you proposed.

1st try: Disable -> Reboot -> Enable OTA did not work out.

2nd try: Do a factory reset -> worked well.

After the reset I copied the file "update-kindle-13.4.5.2_user_452004220.bin" to the sdcard root,

and the kindle almost instantly recognizes the update and I executed this.

So now I am on Fire OS 4.5.2 and for the next step I try to root the kindle.

Installind cve20147911.apk via ADB and executing the App leads to reboot and SuperSu installed.

But Super SU tells me it has no binaries and cannot work.

So I tried KingRoot which took quite long time about 5 Minutes but seems to work well.

So next stepp will be to install safestraps.

EDIT:

Safestrap is installed now and I did a backup of the stock rom and safed it on my computer.

I have read that it is possible to install Nexus and CM Rom in the Stock slot.

Is it safe or will it brick something?

Thanks, Stefan.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Great - thanks for the update. Additional thoughts:

- don't forget to block OTA on 4.5.2 by renaming DeviceSoftwareOTA.apk in /system/priv-app/ to something benign

- once SafeStrap v4 is installed NEVER do a factory reset from the native recovery menu as your device will brick

- in Safestrap Nexus v4 or CM11 are installed in the stock slot overwriting FireOS. Do not create/populate secondary slots as some guides advise.

- suggest making a backup of FireOS before flashing a custom rom (just in case)

- always leave a copy of the Nexus or CM11 zip on your device for recovery purposes (don't need to be the latest release). Won't go into details but you'll be glad the zip is on board if needed as Safestrap can not communicate with the outside world ... even with a tether.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] Stetanchi:
Tanks for your additional remarks.

I did not Block ota and the Kindle already started downloading the Update file, as I enabled WLAN when rooting with kingroot. It is only some percent, but is there a way to stopp the download and delete the file which has been downloaded.

I will disable ota Updates as the next step.

Thanks, Stefan
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
A reboot should delete a partially downloaded OTA update. Just be sure it is a partial. Otherwise the update will be installed on startup.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] spaceywilly:
Hey guys,

I've got a Kindle Fire HDX 7" (Thor) that was on 4.5.5.1. I decided to put Android on it to use it in my car. So far I've managed to downgrade it to 4.5.2 and rooted it, but now I am stuck. I tried using Rashr to install the TWRP recovery but it will only show the grey Kindle Fire logo. From what I understand this is because the bootloader is locked since I got the 4.5.5.1 update and now I can't unlock it. I also tried Safestrap 3.75-b02 and that boots to a black screen. After reading, it seems that you need to be on 3.2.3.2 to get Safestrap working but now I am not able to downgrade. So my question is where do I go from here. Is there any way to get Safestrap working on 4.5.2, or to downgrade to a version that works with

Safe strap?

Edit: not sure how I missed that there is a safestrap 4. Got that working and I'm now in the process of flashing CM11. Huge thanks to everyone on this forum for helping out so much!

In case anyone finds this in the future, here is the full process to go from 4.5.5.1 to Android

1. Downgrade to 3.2.8 using the OTA Capture

2. Upgrade to 4.2.5 manually

3. Root using rootking

4. Install safestrap v4 and reboot to recovery partition.

5. Flash CM11 and open gapps to a new rom slot.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] Stetanchi:
Hi Davey,

finally I disabled OTA, rebooted and the partially downloaded OTA file was deleted :)

Thanks, Stefan.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Great. See following link for best practice. In particular:

Super. Yes, flash Nexus v4, GAaps and SuperSU to the stock slot which will overwrite FireOS.

As with all flashes there is an outside risk something could go wrong. Unlikely but possible. Go in with eyes open.

As a precaution I recommend validating the Nexus v4 rom MD5 with ES File Explorer (or another app that can generate MD5s). Nothing can ruin your day faster than flashing a corrupt image. You'll find the reference MD5 on the Nexus download page.

Thanks mate!

Finally all worked out well and Nexus Rom is running now.:good:

After flashing Nexus Rom / Gapps / SuperSU I rebooted and boot process got stuck spinning aroung the the colored bubbles.

Then I used Power + Vol_UP to restart the Kindle and booted into Safestrap did a whipe there, restarted and finally it booted sucessfully.

Thanks again for guiding me through this, Stefan.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
Well done, especially the recovery from boot hang. If you reflash again (any rom) accept the option to clear cache/dalvik before rebooting. Usually prevents the problem.

You may encounter a few FCs from Play Services early on. Give it time to self-update; usually goes away after a reboot. Post questions as needed. Nexus is a nice rom but getting a little long in the tooth (as is CM11). Both work well but occasionally need a little love.

If you like to tweak consider adding Xposed Framework and a few modules later on. GravityBox is especially useful for adding UI niceties that became standard in later Android releases.

Enjoy!

Hi.

I have HDX Nexus ROM in my HDX kindle (with safestrap). I want to change ROM to CM13 (android 6). But CM13 need twrp.

What I need to do? Install twrp, wipe all, install ROM on first slot? That's all?

Does it good decision? (To change ROM)
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
No - it's not that simple. Taking that path may brick your device. What version of Safestrap do you have installed?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] n1cklan:
Safestrap recovery v3.72 (TWRP v2.7.0.0).

Hm.. Safestrap and TWRP is the same?
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
No. Safestrap emulates TWRP but does not operate as a true recovery.

Good news: the bootloader can be unlocked on your device which when complete will allow you to run any rom customized for HDX including CM13. Bad news: complexity is modest (multiple steps) and you will need access to a Windows PC.

If FireOS is still loaded in the Stock slot can you boot that rom and reply with the version number? That will determine the next step if you want to move forward.
[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] n1cklan:

[Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot] DB126:
You will need to reinstall FireOS 3.2.4 to the STOCK slot (overwriting Nexus v2) and then follow rollback/unlock guidance from there. Take a look at this thread to get and idea of what's involved. As mentioned this is not a quick/simple process. There are no 10-step guides or helpful videos. Decide how much time and effort you are willing to invest. People in the forums will typically respond to specific questions but you'll have to do a fair amount of research on your own.

Hello,

I have a Kindle Fire HDX 7" (3rd Generation). Some time ago I (soft?) bricked it. Back then it was new and nobody knew anything, so lets try again.

When I turn it on it shows the amazon logo for about 20 seconds and then reboots. This continues endlessly.

When I connect it to the computer, I see device manager blink a few times right before the amazon logo appears, but that's it. Thus, I can't get to ADB.

Also, I captured the moment when the kindle appears for a split second and here is what I got from USBDeview:

Understand the guide you are using (written by a respected member of the community) references a fastboot/factory cable.

WiFi doesn't work because you installed Nexus in a secondary slot. WiFi only works from the stock slot with Safestrap v4 and Nexus.

- boot Safestrap recovery; delete Slot 1

- (optional) backup stock slot if it contains anything important

- if you want Nexus flash that rom + GAaps to the STOCK slot

- if you want FireOS reboot and uninstall Safestrap

- do not attempt to backup slot 1 and restore it to the Stock slot; device will brick

[Zopo Speed 7 Plus] ridgemagnet:
Hi all,

I'm in the UK and on the EE network using their 4G, and the Speed 7 downloads stuff really fast when I'm out and about. 4G when it works is really amazing... sitting on a train watching read time HD video streaming without caching is definitely miles better than 3G and to me is a strong selling point of this phone.

However, EE in the UK do charge a lot for data so I have been experimenting with other providers. I now have Three, O2, and Vodaphone PAYG SIMs. None of them have any credit on them but that should be enough to check signal... and where I am at the moment, it is not too impressive, I'm not getting 4G reception from any of them except EE - the rest are giving me 3G. I do realise that with this phone, only your chosen data SIM will get 4G, and the one in the other SIM slot will only do GSM, so I did make sure that data was turned on in the right SIM if I was using two and turned on mobile data etc.

In theory, the speed seven should be perfect for the UK, it has Band 20, Band 7 and Band 3 which should cover all of these providers. Although there are radio utilities out there that are good on signal strength, I haven't found one that tells me what Band I am actually using on 4G. (so if you know...)

So, no matter where you are in the world, I'm interested to know what you're connecting to... what 4G provider do you use, and more importantly, what bands are they on? This would be for the 'International' version of this phone which has the B20/B7/B3 radio. My phone actually reports it is enabled for 4G B1, B2, B3, B4, B7, B17 and B20 but I think that may reflect the different radio modules that can be installed, not the real hardware situation.

thanks in advance!! :cool:
[Zopo Speed 7 Plus] ndouchin:
Hello,

I am waiting my speed 7, it will be deliver in the next days. But if you want to know what frequency you use, try to disable 2 of 3 bands in engineer setting.

I am from France, we have also the 3 bands Band 20, Band 7 and Band 3 used by french operator, with the 2600 mhz.

I hope, I will give you a feedback at the end of the week.

Kind regards.
[Zopo Speed 7 Plus] ridgemagnet:
Salut! The problem is half the providers in the UK sell 4G as a 'premium' service, so it appears unless I activate some of the SIMs (for a pile of money) then I won't be able to validate the specific 4G service :( they communicate in 3G first and then switch only for selected customers... who have paid.

I recently loaded up the 'Three' SIM with some credit(Hutchinson telecom - maybe it would be under that brand in France) and their 4G service seems to be fine as well. Maybe not as good as EE for coverage or speed, but certainly not too bad. 'Three' use Band 20 and Band 3 and EE use Band 7 as well, so that's not very conclusive... yet! I have also been running the phone in dual SIM mode, using both at once, and it works perfectly. You have to choose which SIM to use for each service, and it will (as any Chinese phone) be unable to run 4G at once on both, so you have to choose one of them for calls, one for data, and one for texts. That does not stop you getting incoming calls,texts etc on both lines etc (just sets the default for outgoing) It is a real novelty having that... and two signal strength meters!

I like your idea of turning off the bands in engineer mode, it is not obvious to me where to do that, so if you can point me in the right direction that would be great... I'm using the engineering mode tool...

PS I hope you like the phone! Now that the software is mostly fixed, I like it a lot, you need the latest OTA update to make it usable, so do run the wireless update wizard! Maybe not top quality hardware, but much cheaper, and has a good screen, good speed, big battery and 3Gb memory ... and of course the dual SIM! (Camera, GPS are a bit suspect)...
