FBE == ext4 encryption

OK. So, I've done some reading on the new FBE in Nougat...

https://source.android.com/security/encryption/file-based

https://blog.compass-security.com/2016/10/android-7-0-security-features-direct-boot/

http://www.delaat.net/rp/2016-2017/p45/report.pdf

Based on the above, FBE _should_ only directly affect /data,

(i.e. other partitions _may_ be implicated if the TEE uses them,

but I'm not convinced that matters, since the TEE is consulted

only if FBE is turned on, which is indicated in the filesystem).

On the other hand, the ext4 filesystem needs to be reformatted

to get rid of the FBE flags. I suspect that TWRP does NOT do this.

At least, the feedback it gives (I've just done a _complete_ wipe

of my test Thor, checking _ALL_ available checkboxes) only says

"wiping" for both /data and /data/media, but it says "formatting"

for cache and system...

I'd suggest testing the following **after** making a backup:

adb shell su -c "make_ext4fs /dev/block/mmcblk0p23"

This should not have any adverse effects (beyond obliterating

*all* data on /data *including* /data/media), since Android will

set this up properly again. I've just tested this after verifying

that 'wipe' still left (or re-created) some files on /data...

I sideloaded AEX (since data was pristine, I couldn't push the

ZIP anywhere...) and everything worked as expected.

NB: I have *not* verified that this solves the encryption issue,

only that it won't make things worse...
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
FWIW - TWRP does have the ability format/reformat/resize various partitions including /data. Believe it's buried under the Advance menu. That said, the adb command is probably cleaner/easier/quicker. And safer IMHO as there is no temptation to resize which is usually fatal on Android.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] draxie:
Are you sure?

That functionality must have been removed from the version of TWRP I'm using...

The only remotely similar functionality under Advanced in [MENTION=5749760]ggow[/MENTION]'s 3.1.1-1 build is

Partition SD Card, and when you try to run that with Internal Storage, you get an

error message saying 'You must select a removable device'.

In any case, all I meant was that the Advanced Wipe for Data and Internal Data

does not appear to reformat...

Dear Folks,

for what tablet is this ROM exactly? For the current Fire 7" (2017) tablet?

https://www.amazon.de/dp/B01J90P010?th=1
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
3rd gen HDX. You have a 7th gen. Unfortunately, no root or custom ROMs for that device. Relevant forum: https://xdaforums.com/amazon-fire
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Clarke33:
I haven't been here in quite a while. Is this ROM the best going at this time? I'm still running the 4.4.4 but starting to have some problems and looking for something newer to flash. As always, thanks for the help guys.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Any of the Nougat (7.1.x) ROMs are fine. You'll need to unlock the bootloader to flash anything above KitKat.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Clarke33:
I unlocked the bootloader a couple of years ago, so I'm good to go with that. I imagine I need to up date TWRP before I can flash any Nougat ROM. I just hope I have enough storage to do a backup before wiping. Thanks again and Merry Christmas!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Yep - you'll need TWRP v3 which can be found in the Android Development section. If short on space backup the system and data partitions separately moving each to a host prior to starting the next partition.

FWIW - I'm on AospExtended which has been a solid performer.

Superb rom

How is battery?

BTW new lineage and magisk 15 works flawless

Known bugs are present
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
In my experience battery life is roughly equivalent across well implemented custom ROMs for a specific device with exception to those that claim extra emphasis on raw performance or power efficiency. How kernel and hardware interact have a far greater impact on battery life

all else being equal

. Although I only used LOS 14.1 for a few weeks on a well enjoyed Thor I did not notice a significant difference in drain rate over other Android 7.1 builds (AEX and Slim in particular). Standard YMMV disclaimer.

Any Nougat ROMs for HDX 7 that support bluetooth?

Are there any ROMs for the HDX7 3rd gen that suppurt bluetooth besides those based on KitKat?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
KitKat based ROMs definitely have a leg up but some newer builds are still usable. I'm on AospExtended and can pair with just about anything. See here for best practices and additional commentary.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] thomas.magnum:
Sorry, if this question has been raised before.

My kids both do have a HDX7 running on LineageOS 14.1 since approx. one year. I now want to bring both devices to a more current ROM. What is the best way to update?

Both devices do have a couple of learning apps installed, which have stored certain progress information locally. Do I need to backup this information (how? Helium?) or do the apps and corresponding data remain installed after the update?

Many thanks in advance!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
- backup in TWRP; copy folder (not individual files) to host for safe keeping

- flash updated Lineage zip w/o preliminary wipes

- when prompted agree to wipes of cache and dalvik partitions

- reboot

That should do it. I say 'should' because dirty flashing Lineage w/o GAaps doesn't always work. Give it a whirl and see what happens. Worst case you can always restore backups. More likely you'll need to repeat dirty flash and include a suitable GAaps package. Good luck.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] BOFH2k:
Thanks for that pointer! Made the switch (dirty flash from LOS 14.1 worked in principle, with only a few tweaks required - as described in the AEX thread) and I can now attest to greatly diminished problems with orientation, WiFi and Bluetooth for a thor device on AEX - the latter took me ten attempts to eventually pair my Fujitsu touch pad, but that certainly then helped with finally pairing my Arctic P614 BT headphones...

[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
FTFS is a better fit for most modern mobile devices but I doubt you would realize any real world improvement on a 3rd gen HDX in the absence of exceptionally high IO. The more important question is whether the KitKat era kernel supports F2FS; unfortunately it does not.

Hello guys, is there anyone experiencing charging issue against latest build (Jan 18, 2018)? I have both Apollo and Thor with latest build installed, and since then they can only be charged to 77% battery then stuck there. Tried different USB charger/cable, same issue persists.

Also tried the bug reporter link, seems out of use or I didn't figure out how to use it.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Almost certainly device related. Kernels oversee charging; ROMs rarely get involved.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] fabische:
Great work, Hashcode & ggow, thank you for keeping Apollo alive!

The only nagging thing about your ROM to me is the persistently unavailable Bluetooth capability. Is there a chance that you might fix this?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
BT issues are pervasive across all non-KitKat based ROMs for this device due to kernel limitations. See here for tips on increasing odds for achieving a successful pairing. Once paired most BT devices connect quickly/reliably on subsequent attempts.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] EatingPie:
I asked about OTG in another thread, but decided to bop over here for a response because it's relevant to LineageOS.

Wondering about a software-based possibility...

The B&N Nook HD/HD+ never had an OTG cable made, but verygreen modified the CM 10.1 USB driver to allow software forced OTG mode.

The original diffs are still on github. Way back when, that kernel allowed me to run my Nook HD+ to a powered hub connected to a 500GB HDD, a keyboard and mouse.

As far as I can tell, these modifications still appear in LineageOS 14.1 for OMAP (Nooks), visible in arend's fork. (I think that's the right link.) That means they still work, and might be portable to the HDX version's kernel.

Thoughts?

-Pie
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Me thinks the HW limitation would be difficult to overcome and likely would not see enough use to justify the development effort. The HDX USB port is unpowered necessitating some type of splitter for most OTG applications; makes for a bulky setup. Device is also unresponsive to so called "fastboot" cables (except in 'bulk' mode) suggesting issue lies below the driver level. Then one or more ROMs and likely the kernel would need some attention to accommodate the unique config. Interesting bucket list project for someone with lots of extra time and devices.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] EatingPie:
I think a powered hub would be all that's needed, similar to the Nook HD. And in terms of fastboot, sounds like it's the same as the OTG cable issue maybe as simple as hardware not detecting a certain pinout. (Yeah, I'm being highly optimistic! :))

I do believe it's purely a kernel mod, with a simple user level apk to trigger the switch. I looked at the driver code, but my stopping point arises from having no linux kernel/driver experience, let alone knowledge of the USB bus. :(

-Pie
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
A stand alone powered hub or Y cable (both awkward) is insufficient as that has been tried by many. Nor is the obstacle as simple as a minor kernel tweak or not detecting a specific pinout if past investigations are creditable. Nook and HDX are different beasts. OTG support is lacking on most Fire devices prior to the 5th gen Fire which also sports a micro SD card slot. Prior to that Amazon was angling for all storage to be cloud based. Funny how that didn't work out.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] EatingPie:
Well, so much for optimism. :( But thanks for the info Davey!

I there are any security updates planned? Or eol
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Typically [MENTION=5749760]ggow[/MENTION] indicates if support is being curtailed/withdrawn. Don't see that happening anytime soon given the popularity of LineageOS. Frequency is driven by upstream and resource availability. Might be a bit irregular but it will come. :)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
Yes, I do not plan to stop HDX development any time soon. I will wait for the March patches to be included then do another build. Things have been slow, I have been promoted at work and so extra bandwidth is been used there and also busy at home.

But remember I'm here still doing what I can in what little time I have :)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] MinkyMike:
Is it likely that lineageos will ever run on the rooted fire hd 10 7th gen, or cant the bootloader be unlocked?

sorry if this post is in the wrong place, couldnt see anyone else asking this question..

Thanks
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Unlikely as the bootloader remains locked and root access is dicey. Due to locked bootloader Lineage would likely be limited 12.1 although 13.0 is not out of the question if this device ever gets updated to FireOS v6.

Further inquires can be made here.

New Build is Up

- Dated 15 March 2018

- Security patches up to March 2018

- Upstream Lineage Updates

NOTE: I am working on Lineage-15.1, will let you know when I have made more progress. I have started pushing commits here.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] double-gee:
Thank you so much for this update, it is good to have the March security patches.

Will you - despite your promotion at work, to which I congratulate you - continue to provide security patches?

Maybe you can add a warning that encryption will render the installation useless and that one must wipe the datapartition with TWRP afterwards to get the device recovered.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] pinpad:
Yes, I can confirm this with the version from 15-th March. And this is a known issue, as I can see in the original post. It might be related to the 5G/2.4G modes (I use the 5Ghz band). Try putting airplane mode on and off - for me, it always fixes the issue.

(I wonder, if there is an app, that could detect such situation, and toggle airplane mode automatically - as kind of workaround?)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
In my primary environment selecting the 2.4GHz band dramatically reduced the frequency of spontaneous disconnects. Running AEX ATM but suspect results would be the same on LOS and most other HDX ROMs.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] pinpad:
I switched to 2.4Ghz network, but it did not make any difference. The connection was lost after short period of device being in standby mode, and only switchin the airplane mode on/off restored the wifi connection.

(In my Wifi settings, I have set that WiFi is ON during inactivity only if connected to charger - maybe this has something to do with that issue?)

I guess in my case, a good workaround would be to toggle the airplane mode every time, when I wake the device. Does anybody know an app, or other method to authomatize this. (i.e. turning airplane mode on and off, every time I wake the device?)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Well, yeah. That would be the first thing I would change. There may be a slight impact on battery life. On Thor devices I see a 0.10+0.15% per hour increase in idle drain rates (<5% per 24 hours) keeping the WiFi radio on 7x24 regardless of ROM (Nougat). That is more that offset by improved device responsiveness after waking from a long slumber due to the periodic maintenance windows allowed by doze.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] M-A-X:
Tasker does exactly this for me on my Thor
[Kindle Fire HDX 7" & 8.9" Original Android Develop] pinpad:
I've changed the WiFi settings yesterday (to keep WiFi always on), and until now, no issues. If it is still working in the evening, I will try to switch back to the 5Ghz network.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] DB126:
Will be an interesting test. That said, there is no benefit favoring 5Ghz over 2.4Ghz unless you are experiencing congestion related connectivity issues, especially on a mobile device. Use what is most stable.

[Kindle Fire HDX 7" & 8.9" Original Android Develop] pinpad:

My wifi is working ok (5ghz and 2)

It's on from sleep mode (sleeping for the day).

I leave Bluetooth on. It took me about 10-15 tries to get my BT to pair with a device.

Perhaps try to pair with BT and then leave BT on, see how your wifi behaves.

Another thing I did was turn on then off Airplane mode to get my BT device (headphones) to connect...that worked right away.
