[Q] Bootloader problem

[rocketfans14]

Just putting this out, this is my first time rooting and 'trying to get android' on a device. I recently got a kindle fire 2nd generation but hated the UI and other stuff. My friend suggested me to try rooting it and turn it into an android tablet instead. Following the rooting guide in the forum, I have successfully rooted the device. The next step was installing the 2nd bootloader and TWRP. I followed Hashcode's guide

http://forum.xda-developers.com/showthread.php?t=2100963

but got stuck at step 4, flashing the bootloader. I have searched the thread but have not seen anyone solving the issue I'm having. Using cmd, I got the device to boot into fastboot mode and tried to type in 'fastboot -i 0x1949 flash bootloader otter2-u-boot-prod-10.2.4.bin'. However, it returned an error: cannot load 'otter2-u-boot-prod-10.2.4.bin' : No error. Can someone help me? Your help is much appreciated.

Extra Info:
Amazon Kindle Fire 2 on 10.4.8 (rooted and has SuperSU)
using Windows 7 as workstation
installed KFFirstAide (yes, I have tried option 40 but stuck on <waiting for device>)

Also, I have put the 'otter2-u-boot-prod-10.2.4.bin', 'otter2-twrp-2.6.3.0-recovery.img', and 'otter2-freedom-boot-10.4.6.img' files in the C:\KFFirstAide folder. (I was thinking this might be the reason why it is not working but cannot be sure)

Yea you are kinda right, its because you are running the command from the system32 folder, you need to be cd'd into the folder that the files are in to run that command so "cd c:\kffaide" or w/e first and then run that command. Make sure you check the md5sum of that file before you flash it so you don't end up with a hard brick.

I have checked the md5sum of the files using a program I found here on xda. I'll try to do the cd from file right now and I'll let you know how that went. Thank you for the quick reply.

Ok, I got it up to the TWRP recovery screen. But how do I continue to flash the stock in step 4 after installing cm10.2 and gapps? Also, I do not have a factory fastboot cable.

EDIT
After installing CM10.2 and gapps, I hit reboot on TWRP and has 'unfortunately, com.android.phone has stop working' message popped up on the screen. Is it because I haven't continue to the section "Flashing back to stock" in step 4?

EDIT2 (I don't think this is related to the bootloader problem but I would like some assistance)
I rebooted again and didn't get the 'unfortunately' messages again. However, when I plug it into my computer, the device doesn't charge when it is active but charges when I put it into sleep mode. Is there any way to fix this issue?

That's because a pc doesn't put out as much amperage as a charger so it doesn't charge unless it is idle. Btw I recommend flashing cm 11, it is more up to date and has has improvements made to it that I think aren't added to cm 10.2.

I see. Where can I find CM11 and how do I flash it? Is it just:

1.put the file into /sdcard
2.reboot into TWRP recovery
3.uh, wipe memory?
4.install CM11
5.reboot

correct me if I'm wrong. I wasn't sure if these are the correct steps because there are a lot of different guides and most of them don't have the same steps.

P.S. Since the kindle only has 8gb, is there a way to free up more memory on the device other than the needed memory space for the os?

You have to factory reset to goto it. Download latest gapps as well. It should be in the development section for kf2 here on xda. Lemme find a link.

As to freeing up space all I can say is delete stuff you don't need. I don't tend to get low on my hd but the again I have a 16 gb model.

"Factory reset to go to?" Also, I should put CM11 zip and gapp in sdcard right?

 

[stunts513]

Yes, what I meant was you have to factory reset before flashing cm 11. Kinda like how Amazon os caused a few problems if you didn't factory reset first, same applies when going to cm 11 from a previous cm os.

I'm sorry if this sounds stupid but how do I factory reset my device? I've been working on rooting to installing bootloaders and finally at the point of getting android os on it non stop. Brain cells are dying rapidly...

 

[stunts513]

In twrp hit wipe and choose factory reset.

Thank you so much for all the help. Everything went smoothly after your advises.

Update: It was running well for a while until when it ran out of battery and I recharged it, it won't boot into CM anymore. It just boots into TWRP recovery even if I pressed the option to reboot system and normal boot... What should I do?

 

[stunts513]

Hmm could be a few things, try reflashing then ROM and gapps again, I suspect something with the boot IMG or system image is messed up. If it were the boot IMG I would think it would kick into fastboot though. Feel free to do a wipe of system, cache, and dalvik cache before you flash anything(under wipe>advanced).

I wiped what you said and tried to flash the rom and gapp but when booting, it will still boot into TWRP.

I'll briefly explain what I did prior to the issue.

After everything was all set up, I went to see if there were any updates which there was, the nightlies for CM 11 0518. I hit download and after download was complete, I hit the option "install and reboot". After the orange kindle fire logo came up and briefly after, the blue one, it boot into TWRP. I tried to reboot again but still no changes. So I went ahead and did a factory reset and flashed the two zip files again. The devices still boots into TWRP... I have no idea what to do afterwards and here I am requesting assistance from someone who knows things like these better.

Have you tried wiping internal storage? That's a last resort, maybe somehow your selinux xattribs got messed up. A internal storage wipe would clear them. But it will wipe your sdcard area so backup anything you want to keep over adb first.

[rocketfans14]

I haven't tried wiping the internal storage yet. How do I backup over adb? Also,since you said this might be a last resort method, if it fails, is there no other way to fix it? Not even restoring back to its out of the box state and start all over again with rooting and installing bootloaders etc?

PS. I don't know if it is related to what you are talking about at all but when I plug it into my computer, it doesn't recognize my kindle fire.

 

[stunts513]

It should be recognized as an adb device when plugged in while in recovery, in which case your could run

adb pull /sdcard/ sdcard/

And it should pull it, though that syntax may have been a little off, seems like the syntax when pulling a entire directory isn't quite the same as when pushing one if I remember right but I might be wrong.

You could technically try to restore it with kffa by reflashing to stock, but I don't advise doing that just yet because fastboot is rather limited in comparison to twrp recovery. Twrp gives you access to Linux shell commands over adb whereas fastboot does not and gives you simpler commands.

So in short, to backup, I can just use a adb pull command?

After that, I am lost. I don't really understand what you are saying...

 

[stunts513]

Yes just type

adb pull /sdcard/

and it will pull everything into the directory you are in, which gb be messy if you execute from something like kffa because vBulletin I don't believe it will create a folder called Edward and put the rules there, it will just put all the files right there so it's recommended to specify an empty directory at the end if that command. The rest of the other post was about the comparison if fastboot versus and access. Kindle fire first aid could try to restore it but if something screws up along the way you won't be able to have as much flexibility as you do with twrp to try and fix it. This is hard to explain from my phone...

So the steps are something like:
Backup with adb
Wipe internal storage
Flash the rom and gapp?

Alternative solution:
Restore the whole device
Repeat the root process
Installing the 2nd bootloader again
Flash rom and gapp

And the rest is if I were to restore the device, it is more flexible to use kindle fire first aide than to use TWRP?
