As it stands, there is no possible way to upgrade a (G000T6 Kindle PaperWhite 4 (2018) WiFi, 32GB PW4-32, PW4L) with a FW of 5.11.2 even if it hasn't had a OTA update?

Sorry if this question has been asked already and I assume the answer is no based on the sticky, but I feel like I own this thing that I just can't use until there is a jailbreak available.

Looks like it is a "big nope."

[NiLuJe]

I assume you meant "downgrade", not "upgrade" .

But, yeah, it's starting to get a bit old repeating this, but <= *really* means <=.

G000 PP12 9434 came with 5.11.2 (3541840032)

so 9414 (10/09/2019): 5.12.1 seems updated

A minor mystery, possibly the PW4 are built at more than one location?

I don't think the above was updated as 5.12.2 was the current version being pushed OTA when I powered the above PW4 up and had it updated that is what you'd expect to get. Also powered up in a Faraday cage (zero wi-fi signals detected by my Samsung Note when it's in the cage).

Thanks!

That's possible. Or could possibly be different production lines? The 9414 was Amazon.ca, 32GB, Wi-Fi, without SO.

OK, from jb point of view there is no difference between 5.11.2 and 5.12.1.

Canada goes its way!

[NiLuJe]

One of the early S/N char *should* point to the factory where the device has been manufactured, IIRC.

[Junket]

978146890224-2
9(1)+7(3)+8(1)+1(3)+4(1)+6(3)+8(1)+9(3)+0(1)+2(3)+ 2(1)+4(3) = 118
118 modulo 10 = 110 remainder 8


Err yeah, that would make sense. You would think that there would be an explicit factory/country identifier there.

Hmm. Who knew that Google could keep secrets?. All I see in a cursory search is the unverified claim that Amazon treats ISBN = ASIN --> EAN, country 978 = Bookland. I'll file that under more useless trivia.


@ilovejedd New project for you ;p
since you have some country of origin vs serial number data

Suppose I'll have to find a dataset to sift. Looking at the ID your kindle wiki, it might be the 5th character but I haven't looked closely.

Or found coffee yet

It says (1) Manufacturer, all eink Kindles are B or 9 or G.

[Junket]

Interesting. Thanks for the link

[NiLuJe]

I also have a vague memory of the Android people knowing which one was Foxconn (if any in the eInk Kindle case), f.g. .

[Junket]

This is alleged to be the serial number format for Amazon Fire TV (unconfirmed)

e.g.
709002014106xxxx
7 0 90 02 01 4106 xxxx

Digit
1 Manufacturer: 7 = Foxconn
2 New/Refurb: 0 = new, 1 = refurb
3-4 Model: 90 = Fire TV
5-6 Hardware Revision:
7-8 Unit Revision:
9-12 Date code: YWWD
13-16 Sequential serial number

Hey guys, I just got my first Kindle today, the serial number is 9196 073M, firmware version 5.10.3

I searched this forum and other sites and learned that version 5.10.1.3 is the latest firmware that supports jailbreak, so the chance of jailbreaking my device is zero, right?

Sorry if that question was already answered but a lot of the tutorials I found are outdated.

I might have a way. Not sure if the board still disables PMs for new members but in case it doesn't, please enable your PMs.

Go to the first post of this thread:

Scroll down to the last line below the text and check the date.
See that? It is very recent, only a few weeks old. So it is safe to assume that information is current.
