Sorry guys for spamming this **** now, I do need help, I am doing research already but I bricked my tablet trying to downgrade it. I am running 3.2.4, and I was trying to get 3.1.0 from this guide and I edited my build.prop like he said but I got it bricked when I rebooted it... It turns on when I hold down my power button it turns on, and I can boot into Amazon's default recovery. (the only one I have.) Please help me, I think it bricked because I edited my build.prop file, I can't seem to get ADB access, I am trying to get to it but please help me.

After so many people reporting about bricking after editing build.prop and not changing permissions , you went ahead and did the same thing! Nice job!

As of for now no solution to unbrick. The only way to unbrick it is to connect it with a fastboot cable, making it to enter a Qualcomm 9008 mode. After this you will need some files (.mbn programmers, WICH ARE NOT AVAIABLE, dont try people have tried and failed) so you can enter Download mode 9006. And then flash every single partition in Linux with dd comand.

I had a Thor in this mode (got it from a friend for free), and couldn't unbrick it, so I went to eBay and bought a Motherboard for $39.
I suggest you do the same...
Good luck ;)

First of all i'm sorry for my English. I'm not an American. My device Kindle hdx7" is bricked long time ago. No adb attach and only grey kindle logo. As you say if i bought a Kindle's Motherboard and replace the part could i fix my device? You have solved the problem? could you adb access? I'm eagerly looking foward to your answer. Thankyou have a nice day

Hi, you need to understand that after a brick the only part of the tablet that is not woking is the Motherboard (just the memory chip to be precise, but it is attached to the motherboard), the other parts of the tablet are perfectly working. So you just replace the Motherboard and you have a brand new tablet, which means you get new cpu , new memory chip, new software ect. Remember that you should find the exact motherboard for your tablet. And you need to be handy opening a device, trust me , its not that easy and you can crack things very easily. If you need to make any questions feel free to PM me, im talking from experience.

Thankyou for your answer. As a whole 1. Find correct Motherboard ID in my device. 2. open the tablet not easy and easily crack. 3.Not impossible but difficult work. Right? Oh my god. broken my mental..
if i find correct Motherboard ID and replace Motherboard then my device is working? I understood my device is working correctly. Thankyou for your kindness and effort thankyou.

I'm a little too late to the party, but you could have just requested a replacement. It would cost them next to nothing to repair it. They might have a jig in place that flashes everything via QPST.

Your dead mainboard would make an excellent guinea pig for developing an unbrick method. I'm sure we can find someone on the forum with the required knowledge and equipment that is willing to help. If you're willing to let it go, of course.

Thankyou for everybody

I will´ing to buy used mother board by ebay but i did not. because just item´s cost $35 but shipping fee $46 by usps. I think total $81 cost not benefit. so after sell my device $45 and buy used one(just one month use) only $140. I´m satisfied with my decision because my break kindle is 7inch wif only 16g storage but new one is lte and 64g wow upgrade my device i´m happy Kindle is not popular in my country so new one is $180~190 lte 64g so i decide this method. um~ add answer above qustion i cant replace my device because i did´nt regi. amazon and i lost my device serial number so amazon says they cant replace my device thankyou every one and one more question? I just use my device? How do i regist used device?
