[Q] Replacing Mainboard, Copy old to new?

I have a Kindle Fire 1st Gen.
Seems to have a bad mainboard.
Ordered a new one off ebay, Listed as not being able to register to Amazon.
Is It possible to write my old boards serial number and mac address to the new board?
If so how could I do this? I am not looking to break any laws, I have my own serial number.
I just want to put it on the new part so I can continue using it as I was.
any help would be great
thanks in advance,
New part will be delivered to me on Dec. 7th

The KF 2nd with 1GB of Ram is my choice

[Q] Motherboard Swap

Firstly I apologize if this has been covered, I really can't seem to find it.
My USB connector is broken. Considering the cost of a replacement connector, I was wondering if it's possible to swap a 2nd generation motherboard into a 1st gen unit because the extra RAM would be nice. Does anyone know if this is possible?
Thanks.

Upon further investigation on kf2 forum, it seems like the corporate giant that Amazon is doesn't want anyone modding their products so that they might be used to their full potential. Without a guarantee that the motherboard could be used with custom ROMs even if it can be swapped means it's not worth the risk.

lol! funny guy!

In case anyone is wondering, the folks at PowerBookMedic said there are enough minor differences between 1st gen and 2nd gen motherboards that they aren't interchangeable.

kindle hd7 motherboard swap
I bricked my kindle (rookie mistake), can I swap a 4th gen logic board for a 5th gen? I'm thinking if I can replace the board I can get it running again, does that sound correct?

2nd gen digitizer

Hi, I have searched and searched but cannot find any info about any difference between the 1st and 2nd gen kindle fire digitizers.
Everywhere seems to advertise the digitizers they have as 1st gen and when people ask if they will fit the 2nd gen they say no, it will only fit 1st gen kindle fires.
From the language they use, I can't help thinking that they are referring to the HD or something when they say it won't fit 2nd gen devices.
I did find one place selling parts for the real second gen and the digitizers looks identical to the ones sold by others as 1st gen touch screens, the connectors look the same, everything.
It makes me feel the parts are the same but does anyone here know for sure?
I can't buy from the sole seller I have found specifically selling kf2 parts as he is in the states and I am in the UK else I would have already bought one.
Any help will be graciously received.
Thanks, steve.

Hi, I'm in exactly the same position and cannot figure out the difference. Did you get anywhere with this? Will a digitizer advertised as 1st gen work on a second gen (2012) kindle fire?
Hope you can help,
Cheers,

Really eager to know if the 1st gen ones work for the 2nd gen. I have also scoured the internet and am in completely the same mindeset as you were when you started this thread, having had the same replies from sellers and come to the same conclusion. I'm thinking I might just give a 1st gen digitizer a whirl, but it would really help if you could confirm/refute whether that would be successful.
Thanks.

OK then, fine, I'll answer my own question...
After much searching and scratching of head (and distinct lack of help on any forum I posted on, including XDA ) I found what appeared to be convincing evidence on the internet of a discernible difference between digitizers for the two different models. It would appear that the difference (and what makes the two incompatible) lies with the flex ribbon design. The first gen flex is bigger and the screw holes are in a different place. I have attached two images and it should be quite easy to see what I mean between the two.
To replace mine I ordered one with the correct looking flex. I ensured from my seller that it would be exactly the same as the image as advertised (gotta cover yourself, right). It was not advertised as being 2nd generation and when I asked the seller I was told it was not compatible. I threw caution to the wind and gave it a try. It turned up a couple days later and worked a treat. The only difference between the one I bought and the one already on my tablet was that the new one had a camera 'hole' in the top left corner. I figured it might be for a light sensor or something though mine did not possess such sensor a guess there may have been a few incantations of the 'same' hardware version.
The images I have uploaded are not my own, rather pilfered from the internet, credit to the owner. I also must stress that I do not own a 1st generation device to confirm that this is the case for certain, so maybe someone who does own one could confirm.
Anyway, I hope that helps somebody out who is in the same position that I was a couple of weeks ago.

MCU GS Hardware request VW

Hi fellow XDA members.
My radio GS MCU died due to hardware issues (broken and in not reparable state lanes due my own fault) and i'm searching for a replacement mainboard. Not the SoM with the CPU/MEM/EMMC
It's a VW DVD GS model which i upgraded from PX3 to PX30 to PX5. (Android 5.1, 6.0, 8.0, 9.0) I have contacted several sellers in China but they all reply they cannot deliver me a replacement part due to the age of the hardware. When trying to figure out i noticed that GS still creates mainboards but with an updated layout and chips but the connection ports are still the same. Not sure why they wont deliver me a replacement part.
Does anyone of you have a broken unit but the mainboard OK that i can buy?
Or let me know how i can in contact with the GS Factory. I tried to contact them using their address on the website of the factory but never received a reply.
The pictures included show you the board which is defective.
FlatcablePort layout:
2 ports for the SDcards
1 port for the LCD and its buttons
1 port for the DVD drive.
Thank you for who can help me out in my quest to fix the radio .
Compatible boards:
GS, CHG, XRC-602-MAIN
I'm from the Netherlands/Belgium.

Looks like a GS board Have you had a look on aliexpress, I see there are a number of resellers selling main boards.
The other option is to try Xtrons, you'll need their model code however. I was able to get a GS board out of xtrons quoting their model number a couple of years ago.
Also, consider an HA board from Dasaita - as long as the rear connector layout is the same, you should be ok.

That it is a GS board, that i already knew It was delivered with a PX3 5.1 board and i updated the MCU in the past.
The seller who sent me the device was contacted but he blocked me off with the message: They dont make that radio anymore so no repair parts. Which i think is a BS story but hey who can blame them. Why selling parts when you can sell a complete unit..
I tried several resellers but almost all denied or didnt answer. They only sell complete sets. I'm only able to find the board from the Dasaita, which is not compatible with my system due to the missing ports for the second SD and DVD player. (The one i found on Aliexpress)
Xtrons was the first and only one to reply willing to help but due to Corona i only get an confirmation around march.
I do not have a model number of their device which is the same as the one i have. I did sent all the info i had with some hope they can hook me up.
I found the same system but the reseller sees my messages (Aliexpress lets you know) but did not respond.

It's the same radio with the Android 5.1 manual, the seller only replaced the SoM's and selling them for the price of the newer systems.

Here's one that might be close enough https://a.aliexpress.com/_snm0Pb
Over priced though, you might be able to negotiate.
What happened with the mainboard, possibly repairable?

The board is beyond repairable, i made a screw up and its damaged badly.
A response was received by the seller of the same device stating that they do not sell parts.
I found this one, which meets the requirements and contacted the seller.
https://nl.aliexpress.com/item/32879522002.html
This one also denied.
Update 12-02-2020.
I figured out that a CHG board is also compatible.

Nobody has a board available? I contacted several resellers but all did reply that they did not sent out parts and even the seller where i did get the unit from denied to sent a repair part and wanted me to order a complete new unit..

Kindle Fire HDX 7" (3rd Generation) Replacement Battery - What Part Number?

Hello,
Thank you in advance to anyone who can assist. I have an older model Kindle Fire HDX (3rd Generation) with the 7" screen. Model number starts with "D0FB". Recently the battery has started to fail and no longer holds a charge for any length of time. Everything else about it still works perfectly. I called Amazon and they no longer support this model or carry replacement parts for it, but of course I can upgrade to a new model at a marginal discount because Capitalism! I was hoping someone could direct me to the correct battery for my Fire. I've checked Amazon, eBay and other online retailers and there are lots of variations, some of which I suspect are not legit because the seller spells "Kindle" incorrectly. I just want to make sure I buy the right battery and it won't brick my device. Again I thank you in advance for any assistance.
