[Kindle Fire HDX 7" & 8.9" General] dare2devil:
after a long talk with the customer support i was finally able to make them rollback after them denying that it couldnt be done because my os was 4.2.5 and stuff like that , but i just kept improvising and making excuses until i convinced them that a rollback can be made , i will paste my conversation with them here in hope that it can benefit you and good luck

Initial Question: i would like a rollback with my kindle software please because i am having very bad issues

and i have tried factory reset and issues still presist

01:22 PM PST vinod(Amazon): Hello

01:22 PM PST islam: hello

01:22 PM PST vinod(Amazon): I am sorry to know this. Please be on hold.

01:22 PM PST islam: ok

01:25 PM PST islam: will i be on hold for long?

01:25 PM PST vinod(Amazon): I am checking the device details.

01:25 PM PST islam: it is a kindle fire hdx 7

01:25 PM PST vinod(Amazon): and its software

01:26 PM PST vinod(Amazon): Please give me some time.

01:26 PM PST islam: ok

01:30 PM PST vinod(Amazon): I checked and I see that the software of the kindle is 4.5.2

01:30 PM PST islam: yes

01:30 PM PST vinod(Amazon): We only have the option to roll back the kindle software if the software of the kindle is 4.1.1

01:30 PM PST islam: but i have been experiencing screen flickering and the sleep and auto awake function is not functioning properly since i have updated

01:31 PM PST vinod(Amazon): As the software of the kindle is 4.5.2 we don't have the option to roll back the software

01:31 PM PST islam: i know that it is possible to roll back

01:31 PM PST vinod(Amazon): It is not possible if the kindle software is 4.5.2

01:31 PM PST islam: yes it is

01:31 PM PST vinod(Amazon): it's only possible if the software is 4.1

01:32 PM PST islam: and i know people who have done it

and i cant tolerate the tablet with these issues

i have tried factory reset

and the issues presist

01:33 PM PST vinod(Amazon): Please be on hold Islam.

01:33 PM PST islam: ok

01:34 PM PST vinod(Amazon): We have released a new software update 4.5.3 to correct any errors or bugs in 4.5.2

i see that you purchased the kindle form amazon.co.uk

01:34 PM PST islam: yes

01:34 PM PST vinod(Amazon): So I am not sure if you will be able to update the software from amazon.com manually.

01:35 PM PST islam: i dont think a further upgrade will solve the issue , i am a developer and i am well informed with these issues , the tablet was working fine with the old software and problems rose when i updated

01:36 PM PST islam: i persist that a rollback must be done

01:36 PM PST vinod(Amazon): I see that the kindle is in warranty, as you are facing the same problem after performing the factory reset, we recommend that you contact the customer support of amazon.co.uk for a replacement.

01:36 PM PST islam: a replacement can not be done

01:36 PM PST vinod(Amazon): I will provide their contact details

01:36 PM PST islam: i live in egypt

01:37 PM PST islam: and i had a friend buy the tablet

for me from the uk

and he is no longer in the uk nor will he be going soon

and i will not go to the uk to replace a tablet

i think it is most reasonable to do a rollback , easier for you and easier for me

01:38 PM PST vinod(Amazon): If I have the option to roll back the software I would have already done it for you islam.

As it is 4.5.2 we don't have the option to roll back.

01:38 PM PST islam: please do not say that to me because i already know people who have done it

01:41 PM PST vinod(Amazon): Let me talk to my supervisor to see if he has any such option.

Please be on hold.

01:41 PM PST islam: ok

01:42 PM PST vinod(Amazon): My supervisor is trying from his end.

01:43 PM PST vinod(Amazon): He is trying to Rollback the Tablet to FIRE OS 3.2.8 ?

01:43 PM PST islam: i will appreciate that , but i think to 0s 3.2.4 is better

01:44 PM PST islam: but i think both is okay

01:44 PM PST vinod(Amazon): My supervisor informed me that's the he can only try to OS 3.2.8

01:44 PM PST islam: ok let him proceed please

01:45 PM PST vinod(Amazon): Rollin back the device will :

Cause the Kindle Device to factory reset (please make sure to advise customer of backing up any personal content not already uploaded to Cloud)

01:45 PM PST islam: ok

01:45 PM PST vinod(Amazon): Also informed me that the device will not receive any future updates.

01:45 PM PST islam: okay no problem

01:46 PM PST islam: should i activate wifi for this process or there is no need to?

01:46 PM PST vinod(Amazon): Yes please.

Once you activate wifi let me know and I will ask my supervisor to try from his end.

01:46 PM PST islam: wifi is activated

01:47 PM PST vinod(Amazon): Thank you. Click on sync button 3-4 times

I mean the circles arrow icon

01:47 PM PST islam: done

01:48 PM PST vinod(Amazon): Please make sure the device has a charge of over 40% in order to complete the roll back.

01:48 PM PST islam: it has 49%

01:48 PM PST vinod(Amazon): Thank you.

From supervisor tried from his end and asking you to sync the kindle now.

01:49 PM PST vinod(Amazon): then connect it to a charger and leave it connected to Wi-Fi so the roll back can complete.

If it is successful you will receive a notification once the software has been downloaded to the device

01:49 PM PST islam: i see that a system update process has started on the tablet

01:49 PM PST vinod(Amazon): The length of time to download the software will vary depending on the speed of the your wifi connection.
