[Q] CM KFHD 7 was stable 5 months, now stuck at blue "Kindle" logo??

Hey everyone, first time caller, long time listener here. Apologies for the long post but I figured I'd rather provide all the details upfront.
I've had a KFHD 7" for about a year now and have been lurking around the KFHD dev forums ever since, anxiously awaiting ROM's made available for the 7. Finally in July I took the plunge, and using KFFA, downgraded to stock Kindle OS 7.2.3 and followed opensystem's thread here (http://forum.xda-developers.com/showthread.php?t=2347170) on using FireFlash to install kfhd7-Freedom-boot-7.3.0.img as the bootloader and kfhd7-twrp 2.4.4.0-recovery.img as the recovery. Success and all was beautiful!
Since then I've:
* Updated TWRP to version 2.5.0 via Hashcode's ZIP within TWRP
* Updated CM to version 10.2 (8/12/2013 build)
* Reverted CM to version 10.1 (had stability problems)
* Updated TWRP to version 2.6.3.0 via Hashcode's ZIP within TWRP
* Updated CM to version 10.2 (11/15/2013 build)
* Updated TWRP to version 2.6.3.1 via Hashcode's ZIP within TWRP
All this succeeded, and was stable until Thanksgiving Day (go figure). With my tablet acting somewhat laggy, I rebooted it as I have many times before. This time, when the "Kindle" logo went from Orange & White to Blue & White, it froze. I waited 5, 10, 20 minutes and longer, nothing. Wiped Cache, Dalvik, etc via TWRP and tried again... nothing. Reflashed TWRP 2.6.3.0 and CM 10.1 from zips, still freezes. And then it gets really weird when I factory reset it. Here's the sequence of events:
* Restored Kindle OS 7.2.3 via KFFA and fastboot, turned of Amazon updating
* Used FireFlash to install kfhd7-Freedom-boot-7.3.0.img and kfhd7-twrp 2.4.4.0-recovery.img
* Rebooted to TWRP 2.4.4.0 and installed TWRP 2.6.3.1 via Hash's ZIP
* Rebooted to TWRP 2.6.3.1 and installed CM 11.0 (11/25/2013 build)
* Reinstalled applications, etc.
Beautiful again! Worked for several hours with it yesterday, then decided to reboot again and... BAM! Back to the frozen "Kindle" blue & white logo again. Has anyone ever seen this before? Is there some way I can pull up a display of what the bootloader is doing behind the splash screen to see where it is falling over? (BTW, fastboot works, I can still boot into TWRP, and I have a factory cable)
Thanks in advance to all!

Using Freedom Boot with FireFlash does nothing. FireFlash is for images and freedom boot is not an image. You can push it manually no problem. That's why you have to downgrade your firmware to match the Amazon ROM you are about to flash. You may be having a software issue that can't be fixed. Verify your TWRP first. I would do a fresh install of the ROM you choose. Make sure to "swipe" first. Also, how full is your memory? Do you use the Greenify app to keep cpu usage down? Let me know..

Hey, thanks for the reply. I'm even more confused now than before based on the statement above. Both the seokhun (http://forum.xda-developers.com/showthread.php?t=2271909) and Opensystem (http://forum.xda-developers.com/showthread.php?t=2347170) posts reference using FireFlash to install the kfhd7-Freedom-boot.img. Are you saying I shouldn't install it that way and should instead install via fastboot?
To further clarify, I am doing a full restore of 7.2.3 via Kindle Fire First Aide prior to beginning the procedure. KFFA "pre-roots" the 7.2.3 install and installs the SU app. From there, I'm disabling Amazon OTA updates and then installing ES File Explorer via the Amazon store. ES File Explorer is then used to install the freedom-boot.img as the boot and twrp as the recovery, using the stack override for boot and disabling updates on the recovery. A full reset is done afterwards and before installing CM (cache/dalvik/system wipe). Memory usage should be a non-issue as I haven't yet installed any other applications.
Any thoughts are greatly appreciated!

Opps, wow, I meant you can't flash the bootloader so that's why you downgrade firmware.

[Q] How to install TWRP Recovery on KFHD7 with stock rom?

I have a Kindle Fire HD 7 (7.4.6) rooted and I want to know if there's a way that I can install the TWRP Recovery without flashing any rom at the moment and most important without bricking it. I want to have it installed in case that in a future I want to flash a rom. I think it's a must have tool on this device but I'm not quite sure if it's possible and I don't want to try how-to's that I've read in these forums because it's not what I'm looking for and I don't want to mess up the KF . Any help or advice on this will be very appreciated. :angel:

There is a way but you have to do 1 of 2 things outside of what the standard tutorial says. The newer is checks the boot loader for its version to see if it matches with the is version, if it mismatches it will cause a boot loop. So if you tried the default instructions, you would boot loop since you are on a 7.4.6 os, so you have 2 choices, downgrade the is first to the same as the freedom boot image in the tutorial, or download the latest kinology ROM which has a 7.4.6 freedom boot image inside it that for some reason isn't posted by itself last I check. If you download the kinology ROM you don't have to flash it to install that freedom boot image you can just extract it from the ROM and use it in place of the freedom boot the tutorial tells you to use. Take note of one last thing, make sure to check the box in fire flash at the top with red warning text under it about downgrading the boot loader or you will get stuck with a red screen and that requires a fastboot cable to fix. Anyways here's the tutorial: http://forum.xda-developers.com/showthread.php?t=2271909
I suggest reading through it in its entirety to familiarize yourself. You also have a option for the lazier person, you can simply download the kinology ROM onto the device before flashing 2nd boot loader + twrp (because it will bootloop as I previously mentioned) and first make a backup of data and system, then flash the kinology ROM, then restore your backup you just made. In theory I think that will work.

Thanks for the response, I'm trying that... but before I do this... I want to make sure I'm on the right track. I copied three files on the main kindle directory (fireflash11.apk, kfhd7-freedom-boot-7.4.6.img and kfhd7-twrp-2.6.3.1-recovery.img). I've installed the Fire Flash and now... I'm seeing the interface to flash the boot partition and recovery partition, and the bootloader says the warning thing that the bootloader is not kfhd7-u-boot-prod-7.2.3.bin. That last part is where I'm stuck in... I don't know if checking the box will mess up my kindle... so far, I know that I had to check the "apply stack override", "disable recovery auto update", then unplug cable and hit flash. I'm not sure if I'm still needing the kinology rom since I've downloaded the freedom boot from hashcode.

Wait, so if you were to install 7.4.6 freedomboot, it would bootloop? Why?

Because they were running 7.4.6 so the 7.4.6 bootloader is a match. The problem is that the exploit was patched at 7.3.0 so one really should downgrade to 7.2.3 first because sometimes clicking flash 7.2.3 bootloader while using FireFlash app does not work and you get a bootloop anyway. It's best to drag and drop a ROM onto the internal sd card before flashing. If you do bootloop, just go into TWRP and flash the ROM.

I'm new and a complete noob to this, I'm running 7.4.6, can someone please explain freedom boot and if it would be possible for me to get a custom Rom loaded on my tablet without downgrading to 7.2.3?
Sent from my KFTT using xda premium

Freedom boot if I understand correctly is a patch to the kernel used for second bootloader, I believe it also has version data stored in it that the kindle is checks on boot, if the kernel doesn't match the kindle os version it boot loops into recovery. So yes you can do all without downgrading the os, its just suggested you do because amazon patched the boot loader a while back and downgrading ensures you don't boot loop in case you have an older freedom boot image or you are on 7.4.7. Its probably also flashes the old boot loader too which helps. Never used kffa so not positive about that though.

So how do you suggest I go about flashing my custom Rom, I don't want to downgrade and I want to use fireflash preferable?
Sent from my KFTT using xda premium

I prefer the fire flash method but if you or the program mess up and don't flash the boot loader with the older version first, you will need a fastboot cable to fix it. I haven't ever had a problem with fire flash myself, as long as you check the first box with a bunch of red warning text under it you should be OK.

So... what I should do... run the fire flash app checking that box about the warning of boot loader... and put the files in place and check the "apply stack override" and that's it? I'm getting confused because the post went out of topic...

First, drag and drop what ever ROM you are going to use onto the root of the internal SD card (CM, Paranoid Android, which ever one). This is important. If you do loop, access TWRP and flash the ROM.
Make sure to put the images in the right place, tick "apply stack override" and also tick "disable recovery auto update" and also chaeck "7.2.3 bootloader."
Here is the original tutorial as well for your reference. http://forum.xda-developers.com/showthread.php?t=2271909
Edit: when you do go to flash the ROM from TWRP you first "swipe" then flash the ROM and then wipe only Dalvic and CACHE.

Well... that was fast. I didn't need the Kinology ROM, but I downloaded and dragged it to the Kindle, just in case it boot loop and so have the rom as backup. Just needed the three fiiles. I'll place the instructions clearly just in case anyone wants to do this and worked perfectly for me.
Download:
fireflash11.apk,
kfhd7-freedom-boot-7.4.6.img and
kfhd7-twrp-2.6.3.1-recovery.img.
Copy or Drag & Drop the three files to Kindle Fire HD 7". Make sure to have ON the "allow installations of applications" options found in drop down window (More+ -> Device). Then install the fireflash11.apk, after installation, open the app, if you got the warning message, check the box on the right, then place the kfhd7-freedom-boot-7.4.6.img in the "boot partition" section and tick "apply stack override", then the kfhd7-twrp-2.6.3.1-recovery.img in the "recovery partition" section and tick "disable recovery auto update". Unplug your KFHD7 from the USB, then hit Flash, and that's it! :victory:
No ROM needed, but in case you want like to go in "safe mode" like I did, download the Kinology ROM found here.

Notes:
This tool is designed to work for Amazon OS version 8.4.6. So,using it on any other software might get you into a bootloop,but TWRP recovery and Freedom-boot will work.Because of this,it is recommended to do the following things before using this tool:
Rooting the device.
Backing up any important data.
Placing the ROM and GApps zips on the sdcard in case you get a bootloop,so that you can just flash those in recovery after doing a complete wipe.

Not a single reply? Thanks for the tool.

So, the option to flash Freedom boot and TWRP can only be done from within the OS, huh? Is there a way to do it in fastboot?

Well,the flashing IS done in fastboot by my tool. If you want to flash in the OS,you'll have to use either FireFlash (search for it) or the terminal emulator.
For the TE:
Code:
flash boot kfhd8-u-boot-prod-8.1.4.bin
flash bootloader <filename>.img
flash recovery <filename>.img
reboot
The 8.1.4 bootloader downgrade is to prevent red screens.

You have to disable the driver signature enforcement. Google it. I don't use Windows 8,so I don't know the details.

I think it avoided flashing the 8.2.3 bootloader. I'll take down the download links and have a look. You'll need a fastboot cable.

Safin thanks for your reply. Trying to figure out the issue I manually loaded uboot 8.1.4, twrp 2.7 and freedom 8.4.6 while in fastboot. now I get the kindle fire logo, but it appears to be stuck in a bootloop (let it sit for 6 or 7 minutes with no change). After reading other posts, I'm concerned that when I rooted my KF because I had the latest OTA that the root actually didn't work, so whatever was loaded with the stack didn't take place.
I'll keep messing around today and let you know if anything changes. Also please let me know if you have any ideas.

just to keep you updated:
used fastboot to push the stock boot and recovery found in hashcodes tutorial.
kindle now boots up, and isn't sluggish (like it was after trying the root method on this website).
used the onemelia system.img file he includes in his recovery tool for the image.
checking now to see if his system.img did indeed included superuser access. i'll update.
---------- Post added 9th July 2014 at 12:33 AM ---------- Previous post was 8th July 2014 at 11:58 PM ----------
OK.
I'm on CM11 now.
the system.img of onemeila is indeed pre-rooted and its 8.1.4
First step for the newest firmware is to revert back to 8.1.4 (with that system img its pre-rooted) and then proceed with the rest of your script.
so:
boot into fastboot> flash onemeila system.img (system1.img in his files)
check root
(turn off wifi, freaking thing updated while i was pushing files, so i had to start from scratch as it killed root)
and then the process as described by hashcode in his tutorial.
hope this helps.

If it was sluggish after rooting,the problem was in the root,not my tool.

[Q] Trying to downgrade

Firstly, thanks to SafinWasi and Red_81 who both helped me on other threads, this question follows on from those threads.
I'm trying to downgrade from 7.4.9 user 4952320. Eventually, I will probably install CM11 (I tried once and bricked my device), but for now I just want to downgrade the OS and be able to change the wallpaper, I'm sick of the black paper. (I've tried Stunts wallpaper fix and it didn't work)
When the device upgraded to 7.4.9 I made backups of the whole 12 img files (inc boot0block).
I've read that you need a 7.2.3 boot image to be able to install TWRP as part of the CM11. I obtained a rooted 7.2.3 boot image from Red_81s google drive. I then flashed that boot image and tried rebooting the device. No joy. I got the red triangle. I flashed my 7.4.9 boot image and rebooted. The device rebooted and worked as normal.
I then flashed the 7.2.3 rooted system image and rebooted. Again I got the red triangle. I then flashed the 7.2.3 boot image, (so the device had 7.2.3 system and boot images) but again I got the red triangle.
So, how do you downgrade? Should I have flashed all 3 of the 7.2.3 images? (I don't have the checksums of the images so I recognise if one of the images was corrupted the exercise was doomed to failure.)
By flashing my 7.4.9 system and boot images, my device was restored to functionality, and I learned a bit, but not enough to achieve the goal. I'm hoping someone can show me how to downgrade.

Thought I'd add that I did try Kindle Fire First Aide but got lots of errors about dropbox not being available.

Did you flash the system and recovery? Both are needed to successfully downgrade. I always wipe data too.

You need to flash a custom recovery on a second bootloader as well. You can't just flash the system. You also need to flash the 7.2.3 boot.img and stack override. Any tutorial dealing with this mod will include all the steps. It important to pay attention to details and not skip any steps. http://forum.xda-developers.com/showthread.php?t=2128848

I didn't flash recovery, at my first attempt, just boot, then I tried boot & system. Both tries gave the red triangle.
I've tried again, with all 3 rooted images from your gdrive - recovery, boot & system, and again got the red triangle. I tried again with the 3 images from another source (my own unrooted 7.2.3 backup when I first got the HD7) and again, got the red triangle.
I haven't wiped the data because I would prefer to keep it so I can use the device (and think it should be possible to downgrade without wiping). I haven't been able to find a command to wipe just the cache...
So I'm more than a bit puzzled. The fastboot commands (eg fastboot -i 0x1949 flash boot boot.img) all return with "sending" then "OKAY", then "writing", then "OKAY" so I don't think there's any problem there.
I must be doing something wrong or missing something.

Thanks for your response, but at this stage I don't want to flash a new custom ROM, that may (probably will) come later, but at this stage I want to just downgrade. I've been warned that installing TWRP etc may leave the stock system in a bootloop, so a working stock backup won't be possible.
As I have to downgrade the stock boot image anyway in order to install a custom ROM, I thought I'd downgrade the whole OS in order to have a functioning stock system, then I can make a backup of it in TWRP, then install a custom ROM.
If I'm having problems with a simple downgrade, I might have more severe problems flashing a new ROM and be left with a dead device like I was previously, hence my caution and not wanting to move on until I know I can recover to the previous step if things go wrong.

Did you try downloading the original 7.2.3 from the thread and try flashing them ?

Yes, I did. Tried them twice, in a different order (didn't think it would make a difference but you never know....). Anyway, tried again, this time, wiped data and cache (took 45 mins) and it worked! I now have 7.2.3 and access to Gplay (was already there).
I haven't registered it to my Amazon account yet, so email and contacts don't work, and am wondering if I should go straight to installing a custom ROM. I'm thinking if it isn't registered to Amazon, then they can't update it via OTA...... or can they?
It's been a bit of a task getting this far, but at least I'm more confident about getting into ADB and Fastboot!

well, I know the answer, yes, even though it hasn't logged into an Amazon account (I realise they pre-register them to your account before dispatch), it updated back to 7.4.9 just as I finished the above post and whilst I was thinking I should disable OTA updates using KFFA!
flip. This is turning into hard work. lol, still I know how to do it now.

I was having many issues after the last OTA and got mine to cm-11-20140609-SNAPSHOT-M7 last night. Mine was at 7.4.9 also. I followed rootjunky youtube videos to get mine re-rooted, flashed and working. After getting it rooted, he uses Fire Flash app to put twrp on the Kindle. I deviated a little and put the twrp 2.7.0.0 version other than that, I followed to a T. Once I got all that done, I went on the internet to Hashcode's repository and downloaded the newest cm-11 UNOFFICIAL he had listed directly to the device. I downloaded the latest Gapps from cyanogenmod and then booted into recovery(twrp) and installed. Everything is working beautifully now. Everything seems faster and smoother so far. I did go ahead and do an update from the about area in the settings to cm-11-20140609-SNAPSHOT-M7. I was also able to get all my books that I had purchased through kindle in the kindle reader.

Nice to know. Think I'll be doing something very similar, now I've made backups of 7.4.9 "just in case". Just have to go through all the above again!

Need help with rooting and getting Cyanogenmod on Fire 7 OS 5.1.2

Ive downgraded to 5.1.2 and I found out that you need to run KingRoot a few times to get root, after that how do I get TWRP and then Cyanogenmod? Ive looked everywhere today and a lot of the tutorials are outdated or dont work.
Edit: OK ive rooted now and have Super SU installed, how do I get TWRP? (So I can flash Cyanogenmod and backup)
Im in fastboot and the command "fastboot boot TWRP_Fire_recovery.img" I replaced the "TWRP_Fire_recovery.img" with the TWRP disk image and its failing but I am connected and the device is being recognized. HELP?

TWRP can only be used if FireOS was never updated beyond 5.0.1; your device started life at 5.1.x which can not be rolled back to 5.0.x (brick).
FlashFire can be used to flash custom roms and perform other TWRP like functions. Details here. Thoughts:
- use FlashFire 0.50 or above for best results; avoid any versions <0.31
- accept defaults for most flashes (early videos suggested twiddling various options; unnecessary in later builds)
- operations order matters - especially the positioning of Wipe (different for 'clean' and 'dirty' updates)
- avoid 'heavy' GAaps packages; suggest pico, nano, or micro; don't go any higher than mini
- consult ROM OP for specific instructions
Good luck!
