I have been working on a new version of Safestrap. This aims to allow devices that aren't unlockable and running update-kindle-xx.4.5.2_user_452004120 to install HDX Nexus ROM v4.xx.

I am looking for a Thor and Apollo tester to confirm that they can indeed install Nexus ROM v4 with this.
I have confidence that this works, but if you agree to do this please understand as usual that you do so at your own risk.

So far the new version has been tested on unlocked devices to confirm compatibility and works fine.

The next stage is to test on locked devices, which as I have said have high confidence that it will work.

The prerequisites for test are:
- Must be running stock update-kindle-xx.4.5.2_user_452004120 firmware
- Must be rooted

Things to be aware of with the new version:
- Secondary slots boot, but the WiFi module does not load
- Since the secondary slots work but have no WiFi, you will need to flash Nexus v4 to the stock slot

Let me know if are interested in helping with this.

Congrats!! Rolled the dice and won! :)

Be mighty careful around the 4.5.2 update. Those who received it via OTA (may have been 4.5.3/4.5.4) were treated to a hard brick with no known resolution. Best do the update manually using the procedure/files outlined in this thread. Stay off wifi until 4.5.2 upgrade is complete.

Thor Safestrap - Nexus ROM v4 working

@zamtang has confirmed Safestrap and Nexus ROM v4 is working.

Thank you zamtang for taking a leap of faith, it's not something I would ask without been confident and without serious consideration.

Attached is a screenshot provided by zamtang.

Well...

my device had no safestrap but it was rooted decided to let it auto update so turned on wifi and checked for update. the update centre said no update found, so went and downloaded 4.5.2 from amazon that was taking a lot longer than it should. checked the update center again. a glitchy 4.1.1 was downloading with the download bar glitching from view. i then let it continue pausing 4.5.2 download it then promptly rebooted and attempted to install 4.1.1 the screen went black through the update. hard brick.. i have my warranty and i have another one coming.

here's a tip don't update to 4.1.1 if you are rooted.

hoping to get a kindle with <3.2.6 my first one was originally that <version

Yeah I would say as a rule never let them auto-update.

For the benefit of others ...

NEVER take an OTA update on 3.2.8. Every reported incident has resulted in a hard brick. Keep WiFi off until OTA is blocked. The only effective method is via HDX toolkit. Renaming otacerts won't work on 3.2.8.
