Sunil: I am sorry for that.
darkspr1te: so what is the way forward ?
Sunil: Your chat has come through to the Acer UK Support; hence, we are unable to assist with your enquiry.

darkspr1te: Suni, ive tried that link, i've got nowhere, please I am begging you to help
Sunil: I completely understand your concern, darkspr1te. We are able to assist UK customers with technical queries for products covered under warranty.

darkspr1te: I am a uk customer, I carry a british passport, I can trace my family back 150 years in uk and I purchased the device in UK. what more do you need?
darkspr1te: I am only out of the country on work.
Sunil: darkspr1te, from our records, I see the unit is purchased in Zambia. We cannot pull any information of the unit.
darkspr1te: Thats impossible, I personally purchased it in Portsmouth , we have NO ACER agent or reseller here in Zambia
Sunil: I am sorry for that.
darkspr1te: Please I am begging you, just give me My Secure Boot key for the device that I purchased and own, i can deal with the rest my self
Sunil: Please be online for 2 minutes while I check the information on your query.

darkspr1te: thansk you
Sunil: Thank you.
Sunil: Thank you for staying online. I appreciate your patience.

Sunil: darkspr1te, please let me know the exact issue with the unit to assist you in a better way.

darkspr1te: The unit does not boot, it is only detectedd in windows as Nvidia APX device
Sunil: Alright.
darkspr1te: prior to that it rebooted while watching a movie and in the top left it said fastboot error
Sunil: Okay.
Sunil: darkspr1te, I have checked my records, We cannot come to a conclusion regarding the fault without the unit being physically diagnosed by the technician. I request you to contact South Africa Acer support for more information.

darkspr1te: Then can you please provide me with my Secure Boot key for the device so I can resolve the issue myself.
Sunil: I am so sorry, We do not have such information available.
Sunil: Is there anything else I may help you with?

darkspr1te: actually thats not true,I have a contact in uk who used to work with acer support and he said you can send a BCT config file which is keyed with my boot key and only usable on my device, sadly he left acer otherwise it would be him i would be talking to
Sunil: darkspr1te, If we had the options, we would have definitely helped you. we hope you can understand the situation.

darkspr1te: using the BCT file and nvidia NVFLASH i can fix my device in seconds
Sunil: We do not have such information available.
Sunil: I request you to contact South Africa Acer support for more information.

darkspr1te: then who does
Sunil: Is there anything else I may help you with?

darkspr1te: south africa HAVE NOT responded at all
Sunil: We are able to assist UK customers who reside in UK with technical queries for products covered under warranty.

darkspr1te: fine
Sunil: I request you to contact South Africa Acer support for more information.

Sunil: Is there anything else I may help you with?

darkspr1te: you're joking right ?
Sunil: darkspr1te, If we had the options, we would have definitely helped you. we hope you can understand the situation.

darkspr1te: No I dont understand, I dont know why I have a device that I cannot use because Acer is withholding the key to my own device
darkspr1te: you i had a nexus 7 with same tegra3 cpu and they gave me the secure key within a day of me reqquesting it
Sunil: darkspr1te, you have contacted Acer UK hardware technical support department and we do not have such information available with us. I request you to contact South Africa Acer support for more information.

Sunil: It was a pleasure working with you. Thank you for contacting Acer live chat. Have a nice day.

I will no longer recomend acer devices, I am pulling my github files for the acer as I dont want to be responsable for bricking someone else's device either. I just hope that someone at acer reads this and knows how useless chat/email support is.
