Was MLO-prod the xloader?
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] bournezhang:
i am not sure， I get it from amazon update bin software---update-kindle-8.3.1_3150820

i got those file:u-boot.bin,MLO-dummy,MLO-eng,MLO-prod,modem_update,wankit

i donot know which one is, incommen the MOL is xloader

---------- Post added at 09:06 PM ---------- Previous post was at 09:00 PM ----------

oh no!

the xloader is FAT now,

i still haven't recovery it

i done the step ' dd if=### of=/dev/sdb' and "if=## of=/dev/sdb'

they are not wroking.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
I really hope you didn't just type "sdb" by itself becasue that would reflash the entire partition table and would be very very bad and a pain to recover from. Ok try running this, it should be correct i think

sudo dd if=MLO-prod of=/dev/sdb1 bs=1

You were running all the commands with sudo right? thats kinda needed since it gives the command admin access.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] bournezhang:
yes， i get the su right，and i just running the code as your

but the xloade still come back to FAT even i change it to be unknown as other the parts bootloader

when i connect the emmc to win7 PC,

the xloder become FAT

in common it's should not like this

it's means the xloader not change successful
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
You sure the device path is right? Also I would not let windows even touch my kindles emmc personally. After you run the command again try this and see what happens.

parted /dev/sdb print
Parted /dev/sdb1 print

It should list info about the entire partition table and that specific partition, post back the results please.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Moor Terces:
You might try and post a screen print of how gparted is showing the emmc. That could give us a visual on what you are seeing including the name your computer is giving the partitions etc. This would allow us to provide the exact command you will need to execute. Also the

u-boot.bin from the Amazon update didn't work for me. I had to use the one from hashcode.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] bournezhang:
super~

i have done

i read the message your post at first, i think i make a mistake: i ejckt the EMMC not unmount

so this time i unmount with the Gparted, and then follow your step :copy the code ''sudo dd if=MLO-prod of=/dev/sdb1 bs=1''

and then open the Gparted again , find the xloader part show ' unknow'

then put the M/B back into the tablet.

it's work!!!

i saw the words 'kindle fire' again :laugh::laugh::laugh:

thank you very much stunts513

sorry to trouble you again

my friend meet a new problem as the the pic below

i don't know how to slove
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
First picture isn't loading but I really hope that second picture isn't the kindle's emmc, because if it is you somehow managed to wipe the partition table, the only way to fix that is to flash the entire emmc with someone's emmc image, the problem with this method is the data partition is bigger on some models so the entire emmc image won't flash, as a result the data partition is probably going to be messed up, the good news is that the data partition should still be fixable whether it be from Linux or fastboot. Technically you could install 2nd bootloader + twrp from your pc and then fix it from twrp as well. You are going to need the entire emmc IMG from a 8.9" HD. I remember someone did this and recovered from it but I don't remember which kindle it was but i'm think it was a kf2, someone will need to dump their entire emmc for you to be able to fix this and it will be a huge file, at least 14gb.

yea i usually do, in this case i wasnt even done typing it and it just disappeared... Almost had it happen on my laptop too but i finally figured out what was causing this behavior on my laptop and fixed it, long story short my ubuntu os doesnt work with my touchpad very well, specifically the "disable while typing" feature, thus while i'm typing it starts randomly scrolling and that plus a key in firefox i couldnt pinpont was causing it to go back and forth, finally figured out it was shift + scroll and disabled it in the about:config. :good:

Run the first set of commands on your own kindle while it is in twrp from your computer. Then hookup the hard bricked kindle and run that other command. Tell me if it can boot into twrp after that.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Moor Terces:
Unfortunately, because of the way recovery had to be jammed into the existing bootloader you cannot mount with TWRP. Do you think this would work from him in ADB?
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
i am completely lost, mounting and unmounting works just fine in twrp, otherwise we couldnt flash roms. Hence why he should boot recovery unmount the unessassary partitions if they are mounted and run those commands over adb.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Moor Terces:
I know, it's totally weird. You can't use the mount feature on the Kindle 8.9. It has to do with the way the bootloader is hacked and is also why using the wrong TWRP install process hard bricks so easy. The only way to talk to it is through fastboot or the OS.

Basically TWRP is installed in a split second gap within the existing bootloader. That is why when you boot up you still see the orange logo before the blue takes over. In the earlier versions the bootloader is completely replaced. It totally drove me nuts for awhile after coming from a first gen, and part of the reason I tried to start over and bricked my own.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
That's kinda how it works. Twrp replaces the stock recovery partition, and the bootloader is left untouched, if we so much as touch the bootloader it will break its signature and hard brick. What we did was add a 2nd bootloader in front of the kernel in the bootimg and when the bootloader boots up and tries to execute the kernel it instead executes the second bootloader, from their either the offset kernel will get loaded or it will boot the recovery partition.

I agree the kf1's were nicer in that aspect, made it much easier to flash custom ROMs without worry of hard bricks.

I tried both in windows (Win32DiskImager) and in linux. The computer recognizes card reader but it doesn't recognize the card in it. The card reader is external and it is connected through usb port. I suspect that there are problems with the card supply.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Moor Terces:
Did you open Gparted to see if it recognizes the partitions? If not double check all of your connections as I'm sure you've done a few times. Also make sure you have the proper pin jumped so the card reader thinks there is a card in it. I know that was an issue for a few folks.

Someone want to try reviving my motherboard?

OK, so like a doofus I loaded the wrong ROMs and bricked my KFHD 8.9. I have pulled the motherboard out of the device but I am a software guy and never learned to solder. Is there anyone out there willing to do the recovery for me? I will make it worth your time!

---------- Post added at 09:39 AM ---------- Previous post was at 09:21 AM ----------

Hi guys,

First of all thank you very much for all the details you shared with us about how to unbrick this tablet, I was trying this out myself but it was taking me a huge amount of time before I read this thread and I feel now confident about the chances of reviving this tablet after a month of desperation as I don't like to give up on broken stuff...

I have some questions maybe before I start, my tablet was bricked after flashing via TWRP the FFF and since it shows no sign of life, I did open it and I am familiar with the components right now after studying it, and the pics share here helped me to know that it is very possible to fix it, my main question is to know if I can write the FFF again or another bootloader to replace it via linux command directly to the partition, (please can you be specific about it's naming or location to avoid confusion and further questions) so I don't have to redo all from scratch (rooting and installing CM12, gapps, xposed, etc that I've done before hard bricking it)??? and I know that if I redo the soldering more than once I will destroy it probably, I wil buy a new soldering iron and flux and some other tools to be able to do this, if you can provide advices about the tools to buy i will be grateful and if there is a solution that make it avoidable to solder stuff to the mobo I will try to get them (I know that it is possible to connect via some pins like the buttons on tablet are working and maybe putting up a tool to do this easily for repairing many tablet will be a good project since Amazon warranty is crap and there is many like me who are left behind and have no choice than putting it in trash bin or selling for parts on ebay.

Go to post 35 in this thread and you will see my write up for how to do this. I was as detailed as I could possibly be and linked to all the raw files you need. I am typing this on the same Kindle I brought back to life. By far the hardest part is the soldering. The first time I did it it didn't work and had to resolder everything. I left a leader on the vcc it was so hard just in case haha. If you are carefully not to heat up the board or chips by lingering with your soldering iron you should be OK. Mine survived me doing it twice so it is resilient. One tip is to presolder the tip of the wires and use the iron just to heat the wire. Also got a tiny tip iron that helped and rigged up some clips to help out.

Attempt at unbricking HD8.9

Firstly, thank you kurohyou for the original post & Moor Terces (#31) for the excellent step-by-step guide.

I won’t go into the process of how I managed to brick the Mother -in-laws HD8.9, but suffice it to say I ended up having to try this process after a VERY stupid mistake! Like many people in the Kindle forums I was one of the “well I’ve never bricked anything before” group! The kindle was completely dead (incorrect bootloader) & wouldn’t respond to anything.

Prior to bricking the kindle I took a backup of the boot0block, stock-boot, stock-recovery & stock-system files.

I stripped the motherboard out & connected it as per the instructions using a USB card reader. Using Ubuntu I ran gparted. At first I was constantly getting read /write errors, but I think I tracked that down an incorrect Vcc connection on the very small resistor on the top of the board (I found the other pads fine to solder onto, but that last Vcc was a pig!). Finally I got the card reader accessing the motherboard correctly. The first laptop I tried was still giving lots of read / write errors, but a second laptop (running the same live copy of Ubuntu) read the partitions fine.

I managed to copy both the bootloader (I am already running as root):

Code: dd if=kfhd8-u-boot-prod-8.1.4.bin of=/dev/sdc2 bs=1

and the recovery:

Code: dd if=recovery.img of=/dev/sdc9

but when I came to the boot on partition 10

Code: dd if=boot.img of=/dev/mmblk0p10

it kept giving an error saying that there was no space left on the device.

Looking at gparted (screenshot attached), it says that partition 10 is 8.00MiB. My saved boot.img (v8.5.1) is 8,192KB & the version downloaded fm XDA (v8.1.4) is the same size. Neither will dd across.

I was hoping from previous posts that it might be enough to enter fastboot with just the first two files, but no joy. After re-assembly the kindle is still completely dead.

Does anyone have any suggestions?

Thanks
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Moor Terces:
Hello Chameleon,

I feel your pain. I too would have never imagined that I could make a mistake like that haha. I had a bunch of windows open including an original Kindle root and accidently used it instead of the 8.9 HD version ugh. Also that VCC was definitely the hardest connection. I even left a taped off lead just in case.

As for the Boot.img, I looked around and you are right all of the boot.img files are too big for this type of recovery. I'm certain I got this from the first aid kit and it appears it was different than the files I've seen in the links in the other threads. To help you out why not try the one that I used. It is 4,285kb so should definitely fit. Let me know if it works for you!
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Chameleon846:
Brilliant, thank you! I'll give that one a go (so longs as it's definitely for an HD8.9!). I've got some new wire on order, so I'll wait for that to arrive - I want to minimise the number of times I have to resolder the leads!

I'll let you know how it goes!
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Moor Terces:
It's the exact same file I used so should be good.
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Chameleon846:
OK. New wire arrived (eventually!), however I'm still getting the same problem.

kfhd8-u-boot-prod-8.1.4.bin copies across fine to partition 2 & recovery.img to partition 9,

however when I try to copy boot.img to partition 10 (even with your smaller 4.4MB file) it still says "no space left on device".

In gparted it shows that sdc10 is 8MB, so I'm not sure what's going on.

Is there any way of deleting what's on the whole partition (without trashing the partition table)? Gparted is showing the file system as 'unknown'.

Is it possible that there's some other file (other than boot.img) that's already on that partition that could be causing the problem?

For info, it doesn't seem possible to mount any of the partitions (even those using ext4 file system): "Failed to mount... the device doesn't seem to have a valid NTFS"

Starting to get well outside my knowledge base!!!

## edit ## OK, having just done a bit of resaerch on dd, is it possible that I need to use something like conv=notrunc in the command? Not knowledgeable enough to try anything without advice!

Or, could it be that there are some damaged sectors that are causing the problem?
[8.9" Kindle Fire HD Q&A, Help & Troubleshooting] Chameleon846:
As my daughter would say... OMG!

Schoolboy error... I still had gparted running in the background and it was interfering with the dd command. I re-booted the laptop & went straight into the dd command for the boot.img - it copied first time!

A few anxious minutes later & the Kindle was back together... I plugged it in & got the Kindle Fire logo!!!

I then managed to get back into fastboot, copied my backup images, started from scratch & now have CM11 running perfectly.

Hi, thanks for the great info. I know this is a really old thread, but I'm trying to unbrick my Kindle Fire 8.9 HD, and have all the wires attached except for Vcc to the motherboard (I only attached a wire from VccQ on the board to Vcc on the SD card reader) . Is a wire needed to Vcc on the board or is VccQ on the board sufficient? If Vcc is needed, where is it (I don't see it on the picture in the original post)? When I test the voltage on the VccQ, I'm only getting a reading of 6mV (milliVolts), which seems too little to power up the board.
