Is anyone else having problems with no connectivity from computer to kf2 using latest cm? It charges but no storage or adb. No notification on device when plugged into computer or anything. From Linux lsusb only shows device ("lab 126") when in bootloader before rom boot. No detection even in recovery. Any ideas??? flashed Latest TWRP also

** If everything was done correctly you will at this point see the bootmenu with a BLUE logo during the reboot. **

First of all thank you for putting all this together.

When I reach the above step, I do not see the blue logo. I followed each step without any issues however upon reboot, it boots into the same fastboot screen, no menus. Any ideas on what to try next?

Thanks.
[Kindle Fire 2 Android Development] ripeart:
FYI I've downgraded to 10.2.3, re-rooted successfully, flash all the files, rebooted and still at the normal fastboot screen. I guess next I'll try to downgrade to 10.2.1. After that I'm totally open to suggestions. Thanks again.

EDIT: Holy crap working. I missed the little menu at the bottom as it was booting. Thanks!!!! Excite.

I cant get my Win 7 to see the kf2 with CM 11

I used MS One Drive to get my files to the kf2. My kf2 shows that it is connected but the PC doesn't show it. Even though this thread is pretty old, I was able to cobble together everything to get CM 11 (4.4.4) on my kf2 so thanks very much to hashcode and all of his work to breath new life into my kf2.

May I ask you for help? I was trying to to restore my kindle to 10.2.3 firmware but something didn't work and now shows a red triangle all the time. I cannot reboot-restore, or better said i don't now how to do it.

Well, I've never had that red triangle(actually it was a gray one for me) but seems like you need a factory cable to boot into bootloader as I did when that happened before.

Soft Bricked

Hello All,

First of all, Apologies if I'm posting at wrong place, although it should be correct since I am now trying to recover my KF2.

Background:

Have been Rooting & Installing custom ROMs for a few years now, so not a total noob but **** happens.

Wanted to install CM 10.1 on my rooted KF2 and received my fastboot cable today. Followed instructions on http://wiki.cyanogenmod.org/w/Install_CM_for_otter2. After installing bootloader, recovery & freedomboot, my kindle rebooted up and I decided to copy the ROM and Gapps over without using adb, as it was detected as in my PC as MTP.

I rebooted KF2 to get into TWRP to flash the ROM but got stuck in boot loop. Also got a message with red triangle saying "Your Kindle device cannot boot. You can reset your device to Factory defaults to fix this issue (all data will be deleted from the device).

<Menu options>

To reboot your device press and hold the power button for 4 seconds and release.

To reset to Factory Defaults, press the power button 5 times in succession" googled a little and tried erase cache and erase userdata from fastboot. Still boot looped and unable to get into TWRP.

Finally, I re-flashed the 3 files again, and did a fastboot -i 0x1949 oem recovery and was able to get into TWRP (phewwwww).

Also, used adb to copy over my CM 10 and Gapps (thought my troubles were over) but now TWRP is not able to wipe or mount /data

So, I flashed the 3 files again, and now I am able to get into TWRP, I am able to WIPE, Factory Reset as well. So, I've been inching closer :P

I've copied over CM 10.1 but not able to install it getting error , screenshot attached

assert failed: getprop("ro.product.device") == "blaze_tablet" || getprop("ro.build.product") ==..............................

E: Error Executing updater binary in zip '/sdcard/cm-10.1.3-otter2.zip'

Please advise

Kinda stuck

Hi,

Followed the instructions on the first page, and everything seemed to go without a hitch. The second bootloader is there with the option to boot into twrp, but when i choose to boot into recovery, it just sits there saying "booting..." does anyone know why this would happen?

*update* - I re-did the steps from the first page, but used the Twrp version 2.8.0.0 for this kf2 and it finally booted into twrp! Now to find a good rom...

Hey all.

Been playing with a demo KF2 I was given and successfully converted it to stock OS 10.5, rooted and flashed 2ndBL and TWRP.

Everythings fine except: I lose TWRP on a reboot.

I flash it using fastboot (cable), reboot and get the menu and can go to TWRP.

When I come out of TWRP and oot into OS its all fine.

Reboot again to menu and select TWRP it just sits on 'booting...'

I have to go back into FB and reflash again.

What am I missing?

Ok, so, this:

Flash in FB > Reboot > TWRP = Ok

From TWRP > Reboot System > 2ndBL > Recovery > Boots to TWRP

From TWRP > Reboot System > 2ndBL > Recovery > Boots to TWRP

From TWRP > Reboot System > 2ndBL > Recovery > Boots to TWRP

Rinse & Repeat

TWRP is there and working.

If I then boot to the OS > Shutdown > Reboot > 2ndBL > Recovery = Stuck on 'Booting...'

I have to hold power down to shutdown, but booting OS works fine.

Seems something is changing when I boot to the OS. Does 10.5 flash back a stock recovery or stop it from loading?

Edit2:

Seems I missed a post or two in all these tabs open in Iron :(

Can someone confirm it definitely doesnt work on 10.5 or if there is a fix for 10.5 that Ive missed?

Appreciate it.

stock files

I was very stupid, when I couldn't get adb to pull the original files I gave up and went ahead and flashed away.

I've had to many problems to list right now but after a scary soft brick reboot session and bricking my pants i re flashed all the modded files and I could eventually get the kindle to boot into Amazon o.s but if I restart it I have to re flash everything again to get it to boot for some reason.

Twrp has been getting moody about mounting the SD and so I have been till now, unable to place the cm ROM zip on the card but after managing to get it to boot into Amazon o.s and deleting all drivers it amazingly decided it would actually install the mpt drivers and allowed me access to the SD through windows.

I have put the cm zip on the card and will try it in twrp later but for now whilst its booted I'm giving it a full charge as it had dropped to 55% and I was getting worried cos you can't charge if you can't boot!

I have a fastboot cable and have fastboot access, so I can flash the stock files i should have pulled and recover if needs be if someone can please share there's with me please.

Thanks in advance, Steve.
[Kindle Fire 2 Android Development] steve_htc_wizard:
Hmmm, the kf2 forums seem a little dead, surely there's still some activity going on in here?

Anyway, I cleaned up my pants and got back to work on my kf2, I managed to back up the tablet as it was as although it was unstable it would boot after a couple of attempts and gave me a way to keep it charged and transfer files if I needed.

I shoved the cm11 zip on the internal storage,rebooted to recovery and held my breath lol.

Flashed cm11 and nano gapps and the tablet was booting propper android and super stable!

I am more than relieved!
[Kindle Fire 2 Android Development] Punchieo:
I can't boot TWRP recovery. I cycled through to boot recovery at the blue logo and it just boots forever.

[Kindle Fire 2 Android Development] steve_htc_wizard:
Have you tried re-flashing twrp? I had all sorts of problems initially and it refused to boot things but would boot after I flashed again and then the problems returned after a restart and I had to repeat the process over again but eventually it stopped giving me grief and I flashed the o.s with a zip and my kindle has been a super stable propper tablet since.

Would this work on System version 10.5.1? i saw in a q&a that it looks like i need to downgrade? can i do that at this point?
[Kindle Fire 2 Android Development] adoster:
Actually, I was able to get the 2nd bootloader and everything to get CM 10.2 on my Kindle Fire 2(012) [basic version--speakers, 3.5mm jack, and power button and nothing else] running 10.5.1.

I rooted by using the browser and going to kingroot.net and downloading the app from there. It's a simple/auto-root thing so you just have to tap, tap, tap and it does it all for you. After rooting I was able to reboot into fastboot just fine. Followed the rest of this thread and luckily found a working mirror to download all the files Hashcode originally provided off an xda user--I don't remember who it was but maybe it was in this long thread? Or the "continued" discussion one? (Needless to say, the original download links don't work anymore).

NOTE: I wasn't able to install the latest CM (which is CM-11) off get.cm for Kindle Fire 2 (otter2). TWRP bootloader had some issue executing binary file within the .zip so yeah. 10.2 with appropriate GAPPS (old version, scroll down toward the bottom on the GAPPS download page) works fine and I'm running it now. You might have to install a newer version of TWRP in order to get CM 11 working instead of the one used in this original "HOW TO." Some bugs like Kindle app not working off the Play Store and being unable to unlink/sign out of my Google account but otherwise seems okay.

NOTE 2: It's nice to have it rooted and running a custom ROM for more versatility and customization, but Kindle's hardware is what it is--mediocre and/or slow. So, not an amazing improvement to the point where I'd use it everyday. At the end of it all, this felt more like just a project to see if I could--doesn't add any fundamental usability to me. Hope this was helpful.

To get CM11 flashed, you must flash TWRP 2.7.0.0 which I included in my mirror of files.

Update Procedure?

Hey all!

Been a long time since I pulled out my Otter2 but giving it a friend so thought id give it a once over.

Its currently on 10.5.1_user_5167120 with 2ndBootloader and TWRP.

Was surprised to see that there's an update for it?! -> 10.5.1_user_5174820

Is there a pre-rooted ROM for it or do i basically have to do the entire bootloader thingy all over from scratch?

I have completely forgotten everything about the Otter2!
[Kindle Fire 2 Android Development] desarenezitic:
If you've still got TWRP available then I'd just flash a ROM of your choice. Personally I'm running CM11 as they are still doing regualr updates, I had to flash SuperSU along with the ROM so it's not pre-rooted.
[Kindle Fire 2 Android Development] Dude360:
Sorry, should have been more specific.

Its for stock ROM, do I just flash the .bin from Amazon? I cant even remember how I flashed the first time tbh, was over a year ago since i looked at it!

What steps did you do?

I have a Gen2 that I have just installed KingRoot on.. nothing else has been done/installed.

Is the first thread still valid to follow? (some links looked dead?)

thanks!
[Kindle Fire 2 Android Development] desarenezitic:
I followed this thread, there's some valid links in here still. Double checked, link is here. Most important thing is to ensure you get fastboot working first, took me ages because I didn't have the correct drivers.

Once you're doen there are some updated versions on TWRP floating around, I am using 2.8.0.0.
[Kindle Fire 2 Android Development] xl97:
[MENTION=4830985]desarenezitic[/MENTION]

ok thanks.

whats drivers did you use to get fastboot working?

Since that is important... I want to make sure I use the same and ensure its working as well.

Thanks!
[Kindle Fire 2 Android Development] desarenezitic:
I just used the Amazon official drivers. Get your tablet into fastboot mode and then check device manager to see if they're installed properly.
[Kindle Fire 2 Android Development] xl97:
[MENTION=4830985]desarenezitic[/MENTION]

update:

ok..

I had/have RootKing installed..

I was/am getting a Device ID when doing: adb devices (I see a number in the list)

when I look in device manager.. I see Kindle >> Androind ADB INterface

so I believe I am 'rooted' by installing RootKing (although I havent been able to verify this? only way I read how was to install Google Play store.. and wont let me as it doesnt support the KF (silk?) browser?)

I believe drivers are installed by the Device being listed in ADB command, and the entry in my device manager.

I went to this thread to learn how to put my KF2 in 'fastboot mode'

http://xdaforums.com/showthread.php?t=1668159

those first couple steps to try and get your KF into fastboot mode did -not- work for me.

I used KFFirstAide64 utility and step #15 to rebot my kindle into fastboot mode (preferred method)..

my Kindle now sits with a Fastboot logo on it *green traffic light on the left.. *red traffic light on the right the green one is blinking.

One of the options in this KFFirstAid64 utility is to install 2nd bootloader & TWRP 2.4.4.0 though... which I dont believe is the most current version.

http://teamw.in/site/update/2016/02/05/twrp-3.0.0-0-released.html

Is there something else I should be using? to get into fastboot mode and install a 2nd bootloader (does this have a name or a specific bootloader to use?).. and a more up-to-date TWRP version?

thanks!

Do NOT install twrp unless it was specifically built for the kindle fire 2. It resides in a different place and will not work
[Kindle Fire 2 Android Development] mikeataol:
Do you have a factory cable, either one you bought or made yourself? That's by far the easiest way to get a solid connection in fastboot.

It's been a while , but I dont remember much luck getting an alternate rom or another bootloader on there without having the cable.

---------- Post added at 09:13 PM ---------- Previous post was at 09:11 PM ----------

add: believe it or not, try other USB cables , since you are able to get the traffic light fastboot started on the Kindle.

Here's my abbreviated notes on how to get CM11 on a Kindle Fire 2

Still Works, did one today as a matter of fact

obviously you need all the files, "stack" is a special binary , sure they are here somewhere in XDA

==========

--- Place the TWRP backup / or the ROM and gapps .zip on your device in the /sdcard area

--- ADB commands entered while booted up into STOCK *rooted* Amazon Kindle OS -- May need to enable ADB debugging in Settings:

adb push

stack

/sdcard/

adb shell su -c "dd if=/sdcard/stack of=/dev/block/platform/omap/omap_hsmmc.1/by-name/system bs=6519488 seek=1"

--- Connect fastboot cable, and reboot the device so that "Fastboot" is showing

fastboot -i 0x1949 flash bootloader

otter2-u-boot-prod-10.2.4.bi

n

fastboot -i 0x1949 flash boot

otter2-freedom-boot-10.4.6.img

fastboot -i 0x1949 flash recovery

otter2-twrp-2.7.1.0-recovery.img

fastboot -i 0x1949 reboot

--- If everything was done correctly you will at this point see the bootmenu with a BLUE logo during the reboot

During the blue logo screen press the power button to cycle through options and select "Recovery" to enter TWRP.
[Kindle Fire 2 Android Development] xl97:
Thanks for the reply..

ok.. so I understand you correctly.

1.) Manually place/transfer (drag-n-drop) the following file to my KF2, once I plugg it in and get the 'open directory' prompt...etc

stack - some special no extension file.

TWRP (is this supposed to be the file/name referenced below in the fastboot commands?.. ie: "2.7.10.img"? and if so.. can/should I upgrade to the latest version of 3.xx?)

ROM (Is ROM the same as an /img file?) and if so.. what ROM should I be using?.. is this a TWRP rom -OR- something else? or in ADDITION too? is this where I try to install the 'Android flavor' ROM?

gapps .zip - not sure what this is.. I'll have to search around for it..

where do I get CM11 at? and where is that getting installed in your abbreviated steps?

(I have all files downloaded/saved that are listed in the fastboot commands below)..

so to re-cap the file to place on SD directory:

stack

otter2-freedom-boot-10.4.6.img

otter2-twrp-2.7.0.0-recovery.img (not 3.x version?)

otter2-u-boot-prod-10.2.4.bin

something called: gapps .zip

anything else?

this CM11 goes there too?

Once i have these files placed in the sdcard directory on the KF2.

I can then go back use the KFFirstAide64 utility to get back into a "FASTBOOT" mode..

once there.. run the commands listed below?..

I'm still having a disconnect at what step I actually install the Android ROM/OS (Lollipop/Kitkat..whatever).... and I can treat it as such ever after.. (for other projects/geek stuff)

:laugh:

[MENTION=4992322]mrkhigh[/MENTION]

Not sure what you mean.. the KFFirstAide64 utility has an option to install: 2nd bootloader & TWRP 2.4.4.0 though which mentions it -is- for the KF2...

but as mentioned an old version of TWRP.. (not sure how much that matters?)

thanks everyone!
[Kindle Fire 2 Android Development] mikeataol:
the only files to transfer to the SD card are

the stack file first

then the ROM (which in most cases would be the latest nightly for Otter2/Fire2 get it here: https://www.cmxlog.com/11/otter2/

https://download.cyanogenmod.org/get/jenkins/154698/cm-11-20160320-NIGHTLY-otter2.zip is the latest (i was surprised to see it today still being updated honestly)

then the GAPPS I used at the time was gapps-kk-20131119.zip GAPPS is what give you google play store and basic google compatibility for play store and other apps

the other 3 ( img/bin ) files stay on the pc, in the same directory where you are running the fastboot command from , dont need to xfer them to the fire.

after u get the boot modified to the point where you see the blue screen, u press the power button and then in TWRP install the rom and the gapps

I dont think the latest and greatest twrp is necessary , but if its there FOR THIS DEVICE as 3.x.x.x then sure why not. Make sure you got the right recovery for the device.
[Kindle Fire 2 Android Development] mikeataol:
here is a a recovery image that works for the KF2, newer than the 2.4.4

(goo.im is down and I do NOT see a reference to the otter2 on the TWRP 3 page you were linking to )
