I have lag issues with CM11 and CM10.2. Specifically with playing video. On first boot things run fine but when I hibernate/sleep then youtube, flash or netflix load video very, very slowly. Youtube, and Amazon Prime vids (flash) will load to the point it times out. Netflix just sits at the loading screen. But if I reboot my tablet, and launch those programs to start they run just fine.
[8.9" Kindle Fire HD Android Development] CAL7:
Funny, cause I see opposite issues. Doing real-time tasks, such as playing a video, perform great. Make me think it's a memory management issue, I.e. once a program, like a video player, loads up, then it goes fine. But, switching tasks or losing web pages can take 5+ seconds. With Swype, tapping an input field could see a 5-10 second delay before the keyboard appeared.

I'm looking at a possible MMC issue which has been causing quite a bit of lag once the card starts having to run trim.

I'm just as curious as the rest of you what some debugging will show.

I'll update as I get more info.

Looked at the source code for 8.4.6 and found that the MMC drivers are missing the updates (per the link I posted earlier). At least the first part of block.c is anyway. My guess is that they all are.

FWIW... I have stayed away from Dolphin and performance across the board is much snappier. To replace the Dolphin integration of LsstPass, I reluctantly installed the LastPass browser, and to my total amazement, it's a very quick browser ('tho missing a bunch of features from Dolphin).

adb shell su -c "reboot bootloader"

Just a note that this command [adb shell su -c "reboot bootloader"] works only after 2nd boot loader and TWRP recovery is installed.

This command has no affect on the tablet even if rooted with the Kindle recovery.

Fastboot Continually Waiting

I've searched through the thread and can't find an exact answer to my question, so here goes:

I can't get my Kindle Fire HD 8.9" to boot into fastboot mode.

Here's what I've done:

1. Installed the Android SDK.

2. Installed the Java SDK.

3. Followed these steps to install the Kindle Fire drivers and test adb (adb tests fine).

4. Made sure ADB and additional software installations was allowed in the Fire's settings.

5. Using a solid USB cable (stock one from my Note II; don't have access to my stock Fire one at the moment).

6. Tried to follow your initial fastboot commands. fastboot -i 0x1949 getvar product works (shows "waiting for device"), but the Fire never picks up the fastboot and shows the device in the command prompt.

7. Tried to follow other root and fastboot methods throughout the web, including this recovery tool and these general "flash custom ROM' steps and this First Aide software.

No matter what I do fastboot doesn't work. It's like my Kindle Fire isn't processing or allowing the fastboot commands. Any help would be greatly appreciated! I'd love to try CM on it.

Hi I'm just wanting to double check as I had a couple of issues rooting yesterday the KF First Aide method didn't work for me on my version 8.4.8 and I ended up stuck with an unusable KF for half an hour as it was so sluggish and nothing would load. Good news was I took a deep breath and tried option two on the easy root method which worked perfectly. To be honest I may have made an error when trying the KF First Aide method so I'm not sure it doesn't work on all 8.4.8 KF 8.9.

So I now have root and sdk works great I just want to know if this will work on my KF 8.4.8 8.9". Just a little worried about bricking after my challenges yesterday.

Also what is the benefit of rooting over sideloading googleplay and my launcher/apps of choice?
[8.9" Kindle Fire HD Android Development] _ante_:
I also had no success with KF First Aide with 8.4.8 and ended up using a different method for root. I used seokhun's instructions earlier this evening for installing the 2nd bootloader + TWRP and it worked fine and I've since booted into TWRP, performed a backup from within TWRP, rebooted, etc without issue.

[8.9" Kindle Fire HD Android Development] Moor Terces:
I read your post on the other thread. First of all fastboot cables don't work with the 8.9 so that is a dead end. You should be able to get into fastboot with a little troubleshooting. Most likely the issue is that the driver on your pc got messed up. Go to one of the adb troubleshooting threads to get that sorted.

Did you happen to back up a good system image? If you did then you can flash your backup using adb commands in fastboot once you get it fixed and start over with getting twrp installed.
[8.9" Kindle Fire HD Android Development] volock:
Thanks for the reply. Yeah I realized I made good backups of it before the flash, so just reflashed those and things worked out the second time around. Just a blonde moment for me. Thanks for the help though!
[8.9" Kindle Fire HD Android Development] charlesky:
I've just run into a strange problem. Been using TWRP without issue for many months, but today I tried to reboot to recovery to do a nandroid and just got a black screen. I get the orange and then blue logos, and I got the graphics glitch on the right-hand side as usual, but then the screen goes black and there's nothing. If I plug it in to my PC I can reboot to recovery through adb and TWRP works as normal, but I can't get to it by pressing the power and vol buttons. If I press the power button again the device reboots as normal and everything works fine (running Hashcode's CM11).

I tried reflashing TWRP 2.7 from fastboot (just the recovery, didn't want to touch the bootloader), the flash went fine, but I still have the same problem. The tablet's working fine in normal mode, but it would be useful to be able to get to recovery without having to adb. Before today I never had any problems with recovery. I did a nandroid restore a couple of days ago (had been playing with themes and managed to load one that FCd settings, so I restored a backup), and that seemed to go without a hitch.

Any ideas? Should I reflash the bootloader?

problem installing stack os 8.4.9

Hi, My Kindle Fire HD 8.9 is rooted with superuser installed. The device is running 8.4.9 OS. I was able to successfully install the first line of the shell using adb. However, the second line of the shell command will not install, with the response from the device being: cannot execute permission denied. I have not powered down or rebooted the device and am still in adb mode. I did save the stock partitions to my computer HD. Am I in big trouble? Any suggestions? Thanks for your response...I will keep everything "as-is" until I hear advice from you. Thanks!
[8.9" Kindle Fire HD Android Development] volock:
Can you confirm what lines you mean? The ones from the backup section or which exactly?
[8.9" Kindle Fire HD Android Development] gringoinmex:
The line was the second line in the stack install section. However, I got lucky! Rather than do anything else or unplug the usb cable I took a gamble by going to settings and restoring the device to factory settings. The device now boots up as new, without root, and works well.

My basic question is now: can my Kindle Fire HD 8.9 4g with the 8.4.9 OS be rooted and fastboot installed to run pure android? Any suggestions as to how and/or links? Any help would be very much appreciated!
[8.9" Kindle Fire HD Android Development] volock:
You should be able to downgrade the firmware, then root and flash without any problems. However as far as I know, the 4G isn't working on any of the current ROMs (I could be out of date on this, I have the WiFi only one)

Hi,

I currently have kfhd8-freedom-boot-8.4.3 and kfhd8-freedom-boot-8.4.6 on my Kindle 8.9 and I have fire flash v1.1 installed. This was about a year ago I have not touched it since.

I am trying to upgrade and hashcode mentioned that I should make sure that I have the latest book and twrp installed. I've check and they are kfhd8-freedom-boot-8.4.6 and kfhd8-twrp-2.7.0.0-recovery.

Is it safe to use fire flash to install them? Any instruction?

Hi,

I had trying to upgrade from 4.3 to 4.4 ROM. I read that I need to make sure I have freedom boot 8.4.6 and TWRP 2.7.0.0. So I tried to upgrade, using fireflash, put both boot and recovery in, and choose install scripts (first option). Then reboot.

Now it's stuck withe the blue Kindle Fire logo.

I can get into TWRP recovery. But not sure what I should do next. Can I check if freedom boot is installed correctly? Should I continue to flash the 4.4 PAC-man ROM?

Thanks

-- EDIT

I read the first post again.

[12/09] kfhd8-freedom-boot-8.4.6.img (USED ONLY THE FIRST TIME -- .zip files will have their own boot.img's from now on):

Does it mean I should not have tried to flash the boot img? Should I just go ahead to flash the ROM zip?

<QUOTE> *DONT RE-FLASH FREEDOM-BOOT.IMG LATER AFTER FLASHING CUSTOM ROMS -- IT'S FOR STOCK AMAZON OS ONLY / FIRST INSTALL ONLY* </QUOTE>

So... if I had stupidly forgotten that part and re-flashed the freedom-boot.img over the top of already flashed TWR and CM12, and now the device won't boot normally or into recovery... any suggestions? The only thing I can boot it into is fastboot.

I tried reflashing all my stock backups, it didn't work. I tried TW recovery again and that didn't work.

Any help would be much appreciated!
[8.9" Kindle Fire HD Android Development] Hashcode:
The easiest method to get back into TWRP would be:

- flash TWRP recovery image with fastboot

- flash a boot.img from the CM-12.1 ROM with fastboot ( you can open the zip and pull this file out manually )

- and then run this command on your host "fastboot -i 0x1949 oem recovery"

From there flash a ROM, etc.

So I installed a nightly few weeks ago. But it needed new google apps which I didn't know at the time. So I thought lets try a factory reset, whats the problem in that, right? Nope. Now all my Kindle does is shows Orange logo then blue logo then once it reaches TEAMWIN blue logo screen, it keeps flashing that screen. Computer can't detect it because it keeps rebooting every second, got a factory cable from ebay which does nothing because again the device keeps rebooting. I think I just lost my kindle. :( And googling didn't help as I found only one person who did exactly what I did and he never got any answers.

Is there any way to put it in fastboot mode without connecting it to PC? Like my old LG P500 phone had a combo of buttons that put it in emergency mode and you could repair from there.

[8.9" Kindle Fire HD Android Development] DamnRaL:
Hooray! I did it!

It took me a few days to get it but it wasn't because of Hashcode's instructions, my problem was getting the damn drivers to recognize the Kindle on Adb mode.

I was on an old Xp laptop that was slow as hell, huge pain. Apparently there were two types of drivers (for WinXp anyway). One was just the simple driver to browse the kindles files like an external device which couldn't be recognized by adb.exe & fastboot.exe so after researching and digging I finally found theAmazon drivers for adb, deleted old drivers, installed adb Amazon drivers & eureka adb commands where finally recognized by device!

After that it went fairly quick. Only problem I had in the instructions was the powering up & down + all the plugging & unplugging the USB.

The kindle automatically powers on when you plug it in so I got hung up for alittle bit there on the fastboot portion of the installation. Very Confusing.

Trudged thru & finally figured out a method that worked.

Only issues I've had so far is the browsers are kinda buggy. Default CM12.1 browser is missing some features like press & hold on link to bring up some options is empty.

Chrome browser is constantly flashing tiles in random areas.

Other than that tho pretty cool! Will tinker around with it some more.

Isthere there someplace I should post about bugs & stuff for the developers?

I'm still pretty new here still.
