I know that 5.8.7 can be jail broken, I do not know if all builds of 5.8.7.0.1 can be jail broken.

Any user who wants a link to the newer firmware is welcome to type the additional: ".0.1" into the url for 5.8.7

How to download firmware packages from Amazon that are older than current is one of the FGA (frequently given answers).

Say what?
Are you posting that I wasted my time typing the details of step #7 ?
Of course airplane mode prevents updates, but step #7 update blocking is (was) still working as described.
With one disclaimer further into the thread.

Hmmm, AFAIK simply creating the read-only OTA update prevention directory does no longer work with >5.8.5 or so?! At least I remember to get an auto download of 5.8.6 or so after I simply switched Wifi temporarily on just to autosync the clock, despite having this temp dir correctly created. It was gone after that download, btw. Though definitely set to read-only!

And who knows definitely whether 5.8.7.0.1 on PW3 and KT3 may be downgraded to the respective initial versions or not?

Hopefully, I didn't make a mistake in updating both my touch Kindles deliberately to exactly this version, hoping still to be able to downgrade them later if really needed (e.g. in case of a repair)...

attempted hotfix again, got error message about invalid update or something.

did device reset.

Now I'm stuck with a 5.8.9 device, attempted factory image (step#4), the file just disappears from kindle.

Am I permanently screwed up?

Since you did a reset, and are now at 5.8.9, yes, you are hosed. You can't jailbreak from 5.8.9.

BUT ... earlier, when you said "the jailbreak did not survive" .... you do realize that after any update, you must re-install all the tools you want to use? *Only* the hidden-to-you actual jailbreak survives. If you did not reinstall your KUAL or screensaver hack, or whatever you use -- then you do not actually know if the jailbreak was present.

But that reset --- yeah, that removed the jailbreak. And there's no reversing now, since 5.8.8 or 5.8.9 cannot (yet?) be jailbroken.

Dunno if this clarifies or not, but I thought I'd try .....

And if you did not use the test package attached to the first post, the one that is intended to tell you if the jailbreak is still present ....

Hi there

I am about to start the JB process and was a bit surprised by the result of the Serial Number Nicknames table. I own a 7th generation white kindle bought in Europe in december 2015, its seral number starts with 90DD and the table identify it as a "Kindle Basic (2014) (Australia)".

It sounds a bit strange and I thought it was worth mentioning it...

Only the first appearance of a device is mentioned in the table.
What version firmware was on it when you took it out of the box?

Anything that sat for a year in OZ land without being sold sounds like a prime target to be dump'd onto the European market.

And if they don't sell there, just watch, they will show up in Russia next.
The theory is: put enough fermented potato squeezings into a Russian and they will buy anything.
(My apologies here and now to our Russian members.)

That sequence is called: Global Inventory Management.

That doesn't necessarily mean that the jb did not survive. After upgrading to a new fw it is normal and expected that the hacks stop working; you have to reinstall the hacks (using mobile read package installer) to make it work.

Edit: I see that knc1 and others have commented your posts...
So, hoping to make it clearer.

• The jb does survive to upgrades. So far, it is true up to the latest currently available firmware. It is true for your update also, as far as we can tell.

• But, it is normal, standard procedure (because how the upgrade procedure works) that all the hacks stop working after an upgrade.
  That is: the jb survives, but the hacks don't - because the upgrade does not overwrite the jailbreak that is in a separate partition, but it does overwrite the hacks.

• Since the jb survives, however, it is no problem because all you have to do is to reinstall all the hacks. With most recent firmwares, and I am talking about at least 1-yrs old firmware if not more, you HAVE to use mrpi for this because putting hack .bin files in main directory does not work anymore.
  But I would be really, really surprised if you didn't know this, since it is written anywhere in the jb threads and instructions, and as I said isn't new stuff at all: it has been like that for a very long time

• So I repeat: all you had to do after upgrading to the new firmware - and it's written everywhere - was to re-install all the hacks, simply putting all the .bins together in the mrpi directory and running the mrpi kual plugin (KUAL still worked since the jb was not gone)

• BUT at this point - I missed that part - you did a device reset. Something that the instructions and a very long list of posts all around the forums say you never ever must do. In the instruction that may be even written in red characters if I recall correctly.
  THAT, my friend, does indeed remove the jailbreak as long as the hacks.
  I would tell you that you have to start over the entire jb process, except that you have now updated to a fw version that does not allow downgrading, at least for now.

So yes, you are now screwed, but you weren't after fw upgrade. If only you had read all the instructions... that's a shame!

As cqwang hisself stated that he "did device reset" after manually updarting to 5.8.9, the jb is really gone and he is lost now...

Well, he didn't read the fascinating manual in post #1. What definitely is a MUST do. Never ever do a device reset after successfully jailbreaking. Never!! Whatever happens...

A "repair"? You mean before sending back your Kindle to Amazon for repairing?
As far as I know, they do not repair your Kindle. They send you one new (latest version) at a discounted price, and that's it. Of course, you get it upgraded to the latest version - more or less.

This will keep the chances high to re-jailbreak such a device later on. In other words: Updating to 5.8.8 and later is not recommended in that case, though an already applied jb would survive these updates.

Don't see the need for point a) (and keeping links to Amazon firmwares is "expensive" because they need maintenance as the might broke).
And I don't get the point for b): if you are not going to upgrade anyway, there is no need for you to be able to downgrade. So, it is sufficient that you never do device reset, whatever fw version you are.

Well, what I've meant is simply the updating to a more recent fw version (like e.g. - just to name a number - 5.8.7 if you like to have the new Ember font and the new menu structure). This is recommendated after sucessfully jailbreaking. The "initial factory builds" are really, really outdated and not advisable any longer for productive use. Then it's better NOT to have the "very latest" versions. Just to be (theoretically...) able to to a downgrade again. This could have helped even cqwang. At least as a try.

I had once helped a friend of mine jailbreaking his PW3. Everything was fine. It was the time around when version 5.8.5 or so was the latest. Installed this for hin. Then this guy hadn't correctly read my lips ... an did a factory reset! (I told him definitely and repeatedly: NEVER EVER do that thru all the lifetime of your reader!) But in this case he could be helped by doing all the steps from #1 "downgrading to the intitial build" sucessfully once again. The same situation with a prior update to 5.8.8 or 5.8.9, and he would have been completely out of luck!

Apropos repair: Well, maybe this is a peculiarity here in Good Old Germany; but you can also buy Kindle readers directly in electronic marts "cash-and-carry", not only via Amazon. I've bought ALL my Kindles that way, saving the shipping costs. And in in case of a defect you have two options:
1) If bought less than 2 weeks ago: They will replace the device "no questions asked". (More correctly: they refund it and you're free to choose either the cashback, or buy another device. This could be especially interesting if there is a bargain offer like "Kindle xy 40,- Euros off now!" and you happened to buy it a few days ago for the old price: you can then get the old price refunded and just buy a new one for the reduced costs. )
2) If bought more than 14 days ago: They send it in for repair. And than it could happen that they don't do the replacement/repair when recognizing that the device is "modified": this voids any warranty....

My PW1 has been stolen with the bag it was in (and along with the rest). Hope they may suffer. A LOT. After casting all possible curses in any possible language invoking any possible god or demon, I've then bought a PW3 (and a new bag... and the rest). It has arrived today. Luckily it shipped with firmware 5.8.7.0.1. I've followed the directions of this post: downgraded it to 5.7.4, successfully applied jailbreak, installed survival code and upgraded it back to 5.8.7.0.1.

Everything worked like a charm.

This message is just to say: thank you very much.

Just a note on the "Testing (touchscreen devices listed in title)" section. When you write "If you do not have a /mrpackages on the visible root of your kindle, you either have a damaged JB or the JB was never installed" you should add "or you've not (yet) performed step #8".

Thank you very much for this piece of information!

That's exactly what I wanted to know: 5.8.7.0.1 is downgradeable on a PW3! (And hopefully on a KT3 too...)

In case English is not your first language;
5.8.7.0.1 < 5.8.8
In words, when increasing digits indicate the same sequence as time passing, 5.8.7.0.1 was released prior to 5.8.8

Ref:
https://en.wikipedia.org/wiki/Software_versioning
Where, as used by Amazon/Lab126, the period does not represent a decimal point; it is only a field separator.

Come on people, this is not rocket science.*
Anyone with more than one finger or toe and who can count should be able to figure this out.**

(*) Although rocket science often uses a different versioning scheme.
(**) People with less than one finger or toe should probably not be using a touchscreen device, let alone modifying it.
Note: If you are unable to determine how many fingers and/or toes you have ...
You need help that is not available here.

Sorry, I really can't get your point now. Certainly my native language isn't English and - as always - it's much easier for non native speakers to read than to write in a foreign language. But of course I know what "prior to" means and (as a software engineer) also know lots about version numbering.

I was referring strictly and only to your following statement; I emphasize the relevant part in red just to make sure:

Owing to the very interesting statement by pirl8, now I know. At least for the PW3. That's exactly what I was asking. Everything clarified now.

Your last posting here suggests that you "of course" knew that already too. Why your posting cited above then? Did you know it already before the confirmation by pirl8 in his last posting here, or not?
