Another data point:

- dusted off a thor w/Safestrap v4 and CM 20150726 (old!)

- updated CM to 20160118 from Safestrap w/o incident

- included Open GAaps nano 20160117 and SuperSU 2.46

- my standard update routine (sanitized dirty flash) ...

>> twrp/safestrap 'factory reset' (wipes cache, dalvik and data)

>> flash one package at a time (CM -> GAaps -> SuperSU)

>> clear caches again after final flash (cache, dalvik)

The above procedure has proven to be the most reliable for me across numerous devices/roms. Flashing multiple zips and/or failing to wipe caches sometimes yields issues although it usually works. I like to take the path of least resistance (low curse coefficient). Understand some may want to preserve data partition to reduce post flash reconfiguration time. Reflashing GAaps and SuperSU quick, easy and nearly effortless for the smaller packages.

Safestrap users

: NEVER perform a 'factory reset' from the native Kindle recovery menu! Device will brick; no recovery possible. Factory reset referenced above is performed from within Safestrap recovery.

has anyone ever had battery drain issues? or atleast this devices battery seems to die really quickly for me.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
If you are using Safestrap v4 and have CM11 installed in a secondary slot that's your problem. Best practice is to install roms in the stock slot overwriting FireOS (which can be restored later if needed). If you scan the tread you'll see further discussion of this topic; recent post here.

Battery life of CM11 on HDX quite good due to efficient use of hardware resources and a relatively large battery. The high density screen needs a fairly strong backlight; relatively small adjustments in brightness can have a notable impact on battery life. Best to keep auto-brightness disabled and manually adjust to ambient conditions.

If you like to play twiddling governors can also lead to incremental battery life improvements with no significant impact on performance/responsiveness for most tasks (can't speak to game play). Device is limited by bus/memory/storage characteristics vs raw CPU power. Very hard to peg all 4 cores for more than a few seconds.

This seems great but the computer won't recognise my HDX as a USB device with this, instead it comes up as a removable disk, meaning I can't access files using the USB cable. I have updated the drivers etc. but still no luck. Anyone else have this issue?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Works fine for me (both CM11 and Nexus v4). Thoughts:

- following assumes host is Windows 7 or above

- open Windows device manager

- tether device; note what gets added in device manager (likely under 'portable devices')

- delete that device

- reboot PC and Kindle

- re-tether device; once driver installs should show "Kindle Fire HDX <7 or 8.9>"

If still no luck:

- tether device

- enable USB debugging from developer menu

- should receive a notification (status bar) with various USB options; should be MTP

- experiment with different options

The issue is most likely on with host vs device configuration. Less common:

- change USB cables (amazing how often this works when other fixes fail)

- avoid USB hubs if possible; attach cable directly to host
[Kindle Fire HDX 7" & 8.9" Android Development] loughrey101:
Thanks very much for the advice! I realise that the problem was I was using Slot 1 on Safestrap. Everything worked when flashing on the Stock Slot. I did however notice over time that there were problems with CM11 getting conflicts where after rebooting I was getting a google system stopped working error when trying to unlock the lock screen where it would keep taking me back to the lock screen. I tried the Nexus rom and I don't get that but was getting the google.gapps.com stopped working. I disabled it and enabled it again and it is working so far, so fingers crossed. I fear that issues will occur with these roms in future on the HDX as app and google services updates are required.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Conflicts you report are not an inherent characteristic of the HDX roms. Many users have one or the other installed along with GAaps (Google Services) which auto-update without incident. One of many reasons people opt to ditch FireOS as the Amazon and Google frameworks don't play nice together - at least on FireOS v4 (v5 seems to be more accommodating). No such issue with CM11/Nexus.

If you are still experiencing problems return to Safestrap v4, perform a factory reset (from wipe menu) and reflash the rom of your choice along with the recommended GAaps package in the rom OP. Wipe cache and dalvik partitions when prompted. Reboot. You may receive a few FCs as the device initializes and Google Services auto-updates to the latest versions. Patience - give it a few minutes (or longer) and then reboot; should eventually clear up.

As noted in a previous post be sure to keep a copy of Nexus v4 or CM11 installation image on the device at all times. If you trash your rom it is the only way to recover with Safestrap v4.
[Kindle Fire HDX 7" & 8.9" Android Development] br1an:
Guys, I need help. Appreciate if someone could point me to the correct direction.

The more I read/search the more confused I become. I've already rooted the device.

I've installed safestrap thor 4.0.1, after installing recovery, it will not boot into recovery.

The screen just goes blank, comes on and off.

The current system version is 13.3.2.5_user_325001120.

Can any advise what needs to be done?

I just want to remove this OS and install googles' android.

Thanks!
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
SafeStrap v4 is incompatible with FireOS v3. You should remove it immediately and verify FireOS still boots correctly. Also verify stock recovery is serviceable. Power down the device and then restart using <power>+<vol-up>. If it enters Amazon's recovery all is good. Don't change anything; just reboot.

Recommended path:

- rollback FireOS form 13.3.2.5 -> 13.3.1.0 (necessary for subsequent steps)

- reroot and block OTA with HDX toolkit

- flash TWRP (custom recovery; required for subsequent steps)

- update bootloader to v3.2.3.2

- unlock bootloader

- flash the HDX rom of your choice: CM11, CM12, CM13, SlimLP, Nexus v4 or good old FireOS v4

There are many posts explaining how to accomplish the above tasks. Do some reading and come back with questions. There are no scripts, videos or other 'one stop' solutions; you have some work ahead. But the reward is big as the roms are solid and make the best of the HDX hardware (not to mention gorgeous panel). That said, the HDX is easy to brick so make sure to do your homework before taking action.

Might find this helpful after rolling back to 3.1.0. There are similar posts for the 3.2.5 -> 3.1.0 rollback; not in a position to find them at the moment.

Hi

What ROM is better for performance: this or hdx nexus[4.4]?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Similar performance characteristics; I have run them both. CM11 has a few built in tuning tools so you may prefer that. Both are bound by hardware which, while generally excellent, limits overall performance. HDX strengths are the panel, built quality, audio and battery life. With the right rom it is exceptionally responsive and handles multi-tasking well. However, it is nearly impossible to peg all cores for more than a few seconds, likely due to storage or bus constraints. The GPU is getting long in the tooth; hard core gamers should adjust expectations accordingly. Safestrap reportedly adds some overhead. In limited testing I have not seen that with roms installed in the stock slot which is the recommended configuration for SS v4.

For what it's worth I am quite happy with Nexus v4 after tweaking the default governors.
[Kindle Fire HDX 7" & 8.9" Android Development] n1cklan:
So, HDX Nexus is better for battery life, built quality, audio?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Didn't say that - reread first sentence. Remaining comments pertain to device (hardware) characteristics. Bottom line: it doesn't matter.

Hi,

I flashed cm11(20160118) on unlocked thor and realized that this rom failed to enable Bluetooth PANU(can’t get IP address).

[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Insufficient information for a meaningful response:

- do you have Safestrap v4 installed?

- if Safestrap v4 is not installed what version of FireOS is on the device?

- what errors are you receiving

- why do you believe all those roms can be installed?

Now - if you are on an unlocked device and are stating your battery will not charge above 77% then you have a hardware problem.
[Kindle Fire HDX 7" & 8.9" Android Development] NeverSmile:
Thanks for your support. My device is fully unlocked. And i use twrp 2.8.7.0.

When i reset battery stt, normaly its set to the beginning. But after lock screen, battery history cameback. 4 roms all the same.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
A dev can correct but I believe only bootloader and kernel are shared across those four roms. Given many (hundreds/thousands) of devices use the same combination it seems unlikely there is a lurking bug. Suspect a hardware problem with your device - either with the battery pack itself or the control module within it that (I believe) share some responsibility for reporting current status and charge levels back to the kernel. Resetting stats probably just initializes counters until an actual read can be obtained...possibly after screen lock/unlock.

Ok - let's see how much of that I got wrong ...

- Cm-11 and Hdx nexus ROM use stock kernel 4.5.2

Hi, thank you for this good rom that I installed on my Apollo, but I found a few problems....

1. Battery draining, I lock the tablet before bed at around 1.00 am and wake up at 7.30 am the battery reduce from 95% to 77%, I am not sure if this case is normal ?

2. My LTE does not work, I bought the tablet from secondhand website and the seller did not know exactly which frequency this tablet is supported, but I try to use 4G sim on my ASUS Laser LTE on this tablet, it shows only 3G icon. So how can I check which 4G frequency that can be used on this tablet ?
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
- battery drain due to Safestrap configuration

- see related response: http://xdaforums.com/showthread.php?p=65108137

- LTE does not work on either of the custom roms available for Safestrap v4

Edit: dev subsequently responded that LTE is supported; see next post​

- your only choice for LTE is to use FireOS 4.5.2 or above which can be flashed to stock slot (only). If you go this route be sure to use the Safestrap compatible build. Any other build will likely brick the device.

- Safestrap can be removed if you decide to stick with FireOS

[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
4th gen devices do not support custom roms (yet). However, given you are on 4.5.2 I suspect you may have a 3rd gen. Sideload CPU-Z to identify CPU. 3rd gen uses Snapdragon 800; 4th gen Snapdragon 805.

[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Thanks. Definitely a 4th gen. At present you can not (safely) install a custom ROM. However, you can root with kingroot or allow the device to update to FireOS v5 which should be arriving any day. GAapps (Google Services, Play Store, Apps) can be installed on either version but it goes in MUCH nicer on FireOS v5.

Unfortunately, I won't be able to guide you further as the rest of life is calling. Hopefully someone will jump in with detailed instructions. If not ask again in a few days; hopefully will be able to help then.

BTW - don't worry if the device self-updates. It will likely jump to 4.5.5.1 which also can be rooted (as can 4.5.3; 4.5.4-4.5.5 can not but can be updated to 4.5.5.1).

You installed CM11 in a secondary slot. Reinstall it in the stock slot and delete any/all secondary slots. Safestrap v4 compatible roms should only be installed in the stock slot; secondary slots should not be used.

2. Install Safestrap and follow your instructions?

And what is Gapps and SuperSu do i need it?

So after all i will have my device running only CM11 but no more stock amazon?

What about Google Play Store can i download it after installing CM11 and play like online games and so on? :confused:

For those that are bootloader unlocked, have you ever noticed the advanced reboot option, reboot to recovery just hangs? I've noticed this is only a problem with CM11 and not any other ROM by ggow (e.g.. CM13)...

[Kindle Fire HDX 7" & 8.9" Android Development] Likesoft:
I think there's memory leaking on CM11.

I have an Apollo 64GB with LTE model. and I'm using 3G connection and Wi-Fi both.

I've spotted this memory problem more than 3 month.

Just right after booting, my Apollo has about 1.1GB of free memory(Settings-Apps-Runnings).

But Now I'm using it about 60 hours without rebooting, It has only 550~600MB of free memory.

I've spotted 290MB of free memory after using my apollo without rebooting about 100 hours(infact, 130 hours or more).

When it has only 290MB of free memory, I've experienced reloading launcher repeatedly, not working back button on nav bar on Chrome browser or something.

Sometimes it reboots by itself(not fully. I can see only CM logo when it reboots by itself.), I think the reason of rebooting is memory leaking.

My apollo is 64GB with LTE. I'm using both of 3G connection and Wi-Fi, I've changed build.prop setting of "ro.build.tags=" from test-keys to release-keys, I'm using Kennel Auditor app to change cpu governor from performance to ondemand, enable MPdicision, and some energy saving options.

(I have no idea if there's same problem on Amazon's FireOS. I have very little time of using FireOS.)

I'm sorry if this is well-known problem. I wasn't able to read all replies of this thread.
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Possibly - but unlikely given the number of CM11 installs on HDX devices and the lack of similar observations. As you probably know Android has many receivers which can quietly allow apps to launch in the background on various events. Android itself also caches much of its code over time to improve performance. Unlike older operating systems free memory is a poor indicator of overall system health. Android is quick to swap out older items if the foreground application needs more resources. 75-80% memory utilization reflects an appropriate use of resources; 'free' memory does you no good.

Storage capacity, governor and scheduler tweaks, hotplug algorithms, etc. have little to do with memory performance (KSM might; don't recall if this is available on CM/HDX). You need to expand your repertoire of tools (eg: 'process stats' under developer options; third party apps, etc.) to focus on running processes and services to identify the true culprits. Possible one or more may be OS related suggesting a memory leak; seems doubtful. A potential wild card is LTE as not many Kindles devices are configured this way so not many data points to draw on. Something to look at.
[Kindle Fire HDX 7" & 8.9" Android Development] Likesoft:
Yes, I know what you mean about android memory using policy. but I think 290MB of free memory is weird and when I've got that situation, I clearly surffered from lack of performance.

Another weird thing is, free memory is generally recovered just after killing apps by app killer. but there's no recover for me. the only way is rebooting.

I've found some way to check if there's memory leak, and I did "dumpsys meminfo" from terminal.

This is the result of "dumpsys meminfo" after 73 hours running without rebooting.

Total RAM: 1761980 kB

Free RAM: 557676 kB

Used RAM: 680958 kB

Lost RAM: 523346 kB

I think it's abnormal that the Lost RAM is more than 500MB. but I have no idea how to find the reason of occuring the "Lost RAM".
[Kindle Fire HDX 7" & 8.9" Android Development] DB126:
Agreed. There are a few posts referencing large blocks of "Lost RAM" from CM11 users on various devices. But no more than from stock users. So it could be CM, KitKat or just 'noise'. Perhaps the best way to isolate is backup your current config (TWRP or SafeStrap), clean flash CM11 sans GAaps/apps and monitor over 24-48 hours. If things seem stable begin adding apps/services until the culprit is found. Could also do the same thing with a different rom (eg: Nexus v4). Or just reboot daily - PiTA but not especially time consuming.

CM11 is getting long in the tooth; I don't think the HDX maintainer will spend a lot of time debugging unless there is a clear smoking gun. Hopefully CM12.1 will become available in the coming months for those with locked bootloaders (via Safestrap or FlashFire). CM13 is available today for those with unlocked devices.
