[Q] LG G3 Stuck on fastboot! [FIXED!!!!!] - G3 Q&A, Help & Troubleshooting

I was trying to install TWRP on my phone (LS990, ZV8) using flashify app. This didn't work and after I did so, every time I would try to "reboot into recovery" the phone would get stuck and I would need to pull the battery out. I then read somewhere that the fix was to delete the aboot.img and install the kitkat aboot.img . I tried to do that, and afterwards my phone won't boot at all. It gets stuck and screen turns black and the LED flashes. It sometimes gives me an error message about the bootloader I think. If I try to boot into Download mode, it (sometimes) takes me straight into fastboot instead. When I try to run fastboot and type "devices" I either get back nothing or now I get back a "?". Maybe I don't have the proper driver. Please Please help!!!
Upsdate: Ok so I played with the drivers and although I still can't get a response to "fastboot devices" I tried to flash a recovery and I can get response on the phone to some degree. It says "fastboot: getwarartition-type:recovery" but the cmd prompt on the computer says "cannot load recovery.img".
Maybe I just need to try and flash a bootloader or a download mode. Anyone know where I can get an laf for download mode. Or Have any directions?
Please help me!!!
UPDATE: FIXED IT!!!! What I did was use fastboot to load up an laf.img that I was able to download from someone on here (took a lot of searching to find an laf.img). Even though I was unable to flash the laf (tried a bunch of times and it always gave me that "failure to write" error right at the end), I was able to use fastboot to boot up the laf.img that was on my computer and that got the phone into download mode. Bear in mind that I still wouldn't get the serial number back from "fastboot devices" so if you're having this problem and it doesn't give you the serial number back it's ok. Just try to run some fastboot commands and see if you get a response on the phone, that way you'll know if fastboot is working. Anyway, I was then able to restore it via LGFlashtool. So yup, its fixable!

Unfortunately its hard bricked and the repair center will know that you tampered with it. The nature of the LG bootloader makes it so that you cant write or boot any images using fastboot.
What was wrong with your method is, when you downgrade to KitKat android bootloader you have to also downgrade the bootloader, laf and recovery partition or other wise it bricks. You should have downgraded your phone using LG Flash Tool to KitKat and then root and install whatever you wanted
In your case the version mismatch between your aboot, bootloader and laf partition is the reason why it doesnt work

OK sir, I fixed it so clearly it was not hard bricked (don't say that if you aren't sure, it would have cost me plenty of money to replace that had I not known better). What I did was use fastboot to load up an laf.img that I was able to download from someone on here.

congrats. it is good to know it is fixable

That's awesome to hear. It seems that booting the laf partition does not actually work under fastboot mode for D855 variants which is why I thought it wouldn't work for you

That's great. And what fastboot commands did you use to execute the laf from your computer ?

Hi, sorry for the late reply. I hope you've already fixed it, but if you're still having this problem then let me explain. "laf.img" is the "download mode" partition. The reason you can't use twrp.img (which is a recovery partition image) is because you're "too far gone" so to speak and not even at the point to try and get into recovery. You need to restore download mode first. If you have fastboot properly working (not going to explain that, look it up, there is plenty of info about that on here and other sites), then you can do what I did. (Although from what other people are saying if you have a D855 it will have a locked bootloader and this won't work, I cant tell you about that because I don't have one and haven't played around with one). Anyway, if you have fastboot working properly (read my first post about how it can be working as long as the phone is responsive, even if you don't get back the "devices comman", you may need to play around with the drivers to get this to work) then you need to obtain an laf.img from somwhere. I found a complete set of .img's for my model somewhere (don't remember if it was on this site or somewhere else). It took a lot of searching, but I'm sure you can find one. Once you have that and the working fastboot then run the command "fastboot boot [location of your laf.img]laf.img"
GOOD LUCK!!!

That's interesting...do you have any idea why that would be? Is it a locked bootloader like someone else mentioned? (I don't know much about the D855 model, never got to play with one). Maybe there is a workaround we can come up with...

I realized the problem with the mismatched aboot after the fact... ironically it all worked out because after all of this I am now back to the original kitkat and can just root and flash as you said lol.

If you are able to boot into fastboot, search the latest TWRP and flash it via adb. Connect your device while in fastboot mode and see if it recognize it.
If it does put the recovery file you have downloaded on your desktop and open a command window, press shift and right click at the same time and click on Open command window here.
Type adb devices, if you see a serial number go on and type adb reboot bootloader, then type fastboot flash recovery [ the name of the recovery file you have just downloaded ]
You can do this just by powering on your phone, no need to be already in fastboot mode, just follow the commands.
Press shift and right click : open command window here : adb devices : adb reboot bootloader : fastboot flash recovery [ the name of the recovery file you have just downloaded, do not forget the .img extension ]
fastboot reboot
Once you have a working TWRP you can flash your corresponding backup and go back to stock. The backup will be flashed from TWRP, search for instructions.

http://teamw.in/project/twrp2 and click on the upper right Get TWRP for your device.
Choose your device recovery and download the adb version. That is the .img
Once you have downloaded TWRP put it on your desktop.
Connect your device with your laptop/pc with the unknown sources checked also the usb debugging checked.
Move your mouse over a free space on your desktop, click once just to be sure there is no app or file clicked.
Then press shift and keep it pressed while you right click your mouse.
Press open command window here
in that command window type : adb devices
if you see a serial number type : adb reboot bootloader
then type : fastboot flash recovery openrecovery-twrp-2.8.1.0-m8.img
fastboot reboot
openrecovery-twrp-2.8.1.0-m8 : This is an example, you will write the name of your recovery but it should be pretty much the same.
Good luck.
Are you familiar with
adb/fastboot commands?

You say "pushing a ROM" with what?
You don't push a ROM with TWRP you just flash it.
Or are you talking about pushing the ROM with fastboot?
If you have TWRP than download a stock backup and flash it.
Take a long look at my profile man and if you look just right you will see I've done and asked some stupid things in my travels here on XDA.I can tell you I remember every phone and ridiculous thing I've done to each of them,I still feel crunchy when I think of the mistakes.
We really need more info about the full process.please I'm not trying to offend you and I'm trying to help

If you can't remember what you did, or at least even try to list in detail the steps you did as best you can remember; it makes it very hard for anyone to help.
Saying you followed some tutorials on an entire website (3 websites actually) doesn't tell us jack, and isn't any better than telling us nothing.
Its not even clear the current condition of the phone. Your OP says TWRP doesn't work, then a later post says you are trying things with TWRP, so presumably you have TWRP. But since you never stated that, we can only guess.
What happens when you try to adb push or sideload? What error messages, does it make the phone reboot, stuck on boot screen, etc?
TWRP working? Bootloader is unlocked? If yes to both of those, you should be able to just adb push a ROM, or put one on removable SD with a card reader attached to your computer. Than flash the ROM in TWRP.

I recently decided to root and install a custom rom on my old stock sprint HTC one m8. I unlocked the boot loader via HTC Dev website. I then flashed the TWRP recovery. Since doing the latter step, it's been booting into fast boot all the time! Did you ever figure out what was wrong with your phone?

You only flashed TWRP onto the phone? Or did you root also?
Not nearly enough info to provide the proper help.
Please do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
What version TWRP?
What version SuperSU did you flash (if you got that far)?

LG G3 Hard Break

Hi there,
I have a problem that my LG will not boot the device is stuck at the logo, I've also done a hardware reset but the process also depends on the logo proof and 10min not happened.
In the download mode, I'm not coming.
About the fastboot mode I try to start TWRP, but it appears the TWRP logo and nothing else happens.
How did you manage to get it to this point? What did you do before it didn't boot anymore?
Also, if you manage to get adb access somehow you can just reflash the recovery again
I ran a SuperSU update and then he appeared dialog that I should restart the system and since I have the problem.
How can I flash the recovery again?
If I want to flash TWRP on the fastboot mode, only the TWRP logo and then nothing happens appears.
So you cant enter download mode or recovery? And you cant turn on phone?
No download mode is not only possible fastboot mode. If I we want to install Recovery in fastboot mode, shown below
Command: fastboot flash recovery recovery .img
Error on LG G3:
Error: Command never completed
Error: Auto CM012 error
Error: Command completed with errors

I ran a SuperSU update and then he appeared dialog that I should restart the system and since I have the problem.
How can I flash the recovery again?
If I want to flash TWRP on the fastboot mode, only the TWRP logo and then nothing happens appears.

Something does not compute in this at all. SuperSU should not have caused your phone to brick like that.
Is there something else you are not telling us about how your phone was set up? Were you doing anything before you updated SuperSU? This looks like a case of where you flashed the wrong image on your phone, if you ask me.
SuperSU is not phone specific, so I'm having a hard time believing SuperSU did this.
Something else must have happened that you are not telling us. You need to lay out in order, everything you did to your phone up to the point of updating SuperSU.
Also, SuperSU asks how to update: normal or via recovery. Which way did you choose? Either one shouldn't matter, but it's a start.
I had the ROM KNVIRUS V11, since I got the message that an update to SuperSU are available. The update I installed then I get the message that the device must be restarted for the update to be finished and since I have the problem.
I wanted to start the download mode just in fastboot mode, unfortunately without success.
command to start the download mode: fastboot boot laf.img
Result: fs2.directupload.net/images/141219/p68gn6y5.jpg
What I do not understand whatever I command in fastboot mode I enter I get these error messages:

Did you flash the correct laf.img file for your model of phone? If not, that could be part of it. What model of the G3 are you using and where exactly did you obtain the laf.img file from?
SuperSU update should I install because the PlayStore has shown that there is an update.
laf.img I downloaded here: http://forum.xda-developers.com/showthread.php?t=2766437
I found a thread has to ängliches problem: http://forum.xda-developers.com/lg-g3/general/guide-how-to-restore-download-mode-t2897257

Well, there you go. I have NO idea for what version of the G3 that thread was for. The guy never states which version it is. You do not, repeat, do NOT flash anything to system, boot, etc for this phone unless you know for sure it's for YOUR model of the G3. There are various models of the G3. For example, mine is the Verizon model (VZ985). There is an AT&T model (DS855), and numerous others, especially for those overseas. I would not and should not flash the DS855 boot image to my VS985 boot image. It will brick the phone as you have found out the hard way from what I can tell.
You just flashed something you have NO idea which version it was for. You may have completely bricked your phone. I'm not entirely sure, but you need to find the correct stock images for your phone and flash them back.
You need to go here and figure out which model of G3 you have:
http://forum.xda-developers.com/showthread.php?t=2791269
After that, you need to go and find the correct stock image files and flash those back onto your phone. Since this are NOT img files, you cannot fastboot flash them. You muse use either KDZ or TOT files depending on which ones are available for your model of phone:
http://lg-firmware-rom.com/
or
http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/
Then, you have to use the correct tool to flash these files depending on if they are KDZ or TOT file:
http://forum.xda-developers.com/showthread.php?t=2785089
Hopefully, flashing back to the correct stock image will fix you up. However, you better make darned sure which model of phone you have BEFORE you even attempt it. Once you figure out which model of G3 you have, post here and ask. Otherwise, you could bork your phone up even worse to where it may not be recoverable. Hopefully, it's not at that state right now.
I have LG G3 16GB EU version.
As I have written on the first page, I get nothing into download mode so I can not flash it.
What I can not understand why no command in fastboot mode works no matter what I type, I always get the error message: FAILED (remote: flash write failure)

Again, did you verify with the link you posted for the image file that it was indeed for YOUR model of your phone? If not, you probably have bricked it.
You need to go and follow the links I posted which tell you how to flash back to stock.
There was no reason to go into fastboot mode for SuperSU. I don't know why you felt you had to do that.
Also, the second link you posted has the thread pretty much deleted. The OP said he was incorrect in what he posted (whatever it was I don't know since he deleted it), so it was removed due to it not working as stated.
Go back to the links I posted to flash back to stock on your model. If what you say you have is the European model, then this would be the KDZ file you want:
http://storagecow.eu/Xda/LG G3/Stock/Europe Common 16G D85510A_00.kdz
I would verify for sure that is what your phone is before continuing or else, you'll bork your phone up even worse than it is already.
The boot image you flashed is probably for the Korean version of the phone and that's why everything is messed up.
If you are not sure on how to do this, then you might want to find someone near you who does.
Just remember, just because a post says it's for the G3 doesn't mean it's specifically for YOUR model of the G3. You need to verify for sure that it is. Most have the model number in the thread's title.
LG G3 Fastboot
well i have the same problem for a week every command was giving error, but then used this command "fastboot boot twrp.img" i was able to get into the recovery from there i wiped everything and then rebooted but nothing happened but then somehow (I DO NOT KNOW HOW) i was able to get into the download mode so i flashed the stock firmware of my lg g3 D855 and everything was going good and i was just setting up my phone and then suddenly it turned off and again booted into the fastboot mode, WTF , i was just installing some apps from playstore man, and now when i try to boot into twrp it is just stuck on twrp image on the whole screen

But now i am stuck again on fastboot mode and this time i was not rooted and did not had twrp installed so now when i try to use the "fastboot boot twrp.img " my device will reboot and then will be stuck on twrp logo on the screen
I have the same problem...
I ran stock OTA update 20f, since a couple of weeks ago. While I had my phone on the table and it was runing voice recorder soft it restarted once and then after a couple of minutes again. This time it never booted but stuck at the LG screen.
Never rooted, never installed anything other than the OTA 20e and 20f updates. I have not flashed anything to the phone other than the official OTA.
Doesn't boot to anything other than fastboot. Recovery starts but after confirming twice it reboots and stuck still.
If I boot to Download Mode it goes to fastboot, if I wait long enough on regular boot that only shows the LG logo it will eventually go to fastboot.
Running "fastboot.exe boot openrecovery-twrp-2.8.4.0-d855.img" gives me the same error messages, stuck at the TWRP logo screen. I found the ADB port is connected but when running "adb devices" it says "LGD855..... offline". I didn't enable ADB before the device crashed and I can't enable it in TWRP because it doesn't start properly.
I have the 32GB D855 European unlocked. I belive this is hardware problem and will send it for repairs.

Oeps, `flash write failure` brings back memory`s of the emmc failure with Samsung devices where the sdcard is no longer readable and can not be written on. Send it in for repair, there is no other way and they`ll probably replace the motherboard.

That's right. I tested to boot Philz recovery and it freezes at the text.
Mine says actually:
Error: Command never completed
Error: Auto CMD12 error
Error: Command never completed
Error: Command timeout error
Failed to send stop command
Failed reading block @ 1
mmc read failure misc 2048
The CMD12 is according to emmc spec a "Stop command".
So this is a hardware fault and not a software one.

System corrupted, laf removed, fastboot doesnt work, stock recovery is useless.

Alright here's the story. I was trying to put CM on this rooted LP 5.0.1 tmobile d851 (20e i think). I backed up and removed the LAF in order to access fastboot so i could flash the custom recovery. fastboot would send the recovery, but the phone would never actually flash the img to the device and report done. Even "fastboot reboot" did nothing. "fastboot devices" reported the serial as "?" and no driver or Arch/CentOS/other windows installs would get fastboot working. fastboot showed up as Marshal london bootloader in device manager.
So then i tried using flash_image from inside of rooted LP to flash the recovery however i ran into PIE errors that could be fixed by replacing /usr/bin/linker. So I found a patched version, rm -rf the old one and tried to cp in the new one. This seemed like a totally valid idea from my linux experience. Buuuut crap. Nothing works. No commands are accepted because I deleted linker. I rebooted cause I had no better alternative and i get a dead android "no command".... Looks like I found the single best way to kill an android installation.
Now im really stuck because i cant use download mode (LAF) to restore because it has been deleted to access fastboot and fastboot wont actually do anything so I can't restore the laf. There is no custom recovery. The stock recovery adb sideload will only let me install OTAs and far as i know there isn't a FULL OTA that will restore the entire system. I even tried the qualcomm 9008 hard brick method with boardDiag, but that doesnt work on tmobile.
I see a few options:
Somehow get fastboot and then download mode working
Wait for a 6.0 OTA and hope it updates the linker bin
advise?
also, the LG logo appears on screen and the LG serial port (the one used for the LG flasher tool) is present in my device manager for a good 15secs before the no command android shows up. I tried lg flasher tool with this time window but it always cut out before the tool could get anywhere.
Edit: This is what the fastboot process would look like:
Screen right after fastboot boot:
[500] Fastboot mode started
[600] -- reset --
[610] -- portchange --
[710] fastboot: processing commands
fastboot erase aboot brings:
erasing 'aboot' ... on command prompt
and
[346290] fastboot: getvarartition-type:aboot
[346350] fastboot: erase:aboot
after those appear it just hangs like that
unplugging it after that command gives me:

Did you ever find a fix for this?
No, its either professional jtag, or maybe the MM stock ota update zip will fix it if it includes the linker. i havent found this ota on the Internets yet though.

You have to see google fix lg g3 on Qualcomm mode...I mean hard brick fix....
Download as instructed
I think it will be fixed
Recently I fixed lg g3 from only led blink no signal to pc and only vibrate and others
That doesn't work on tmobile G3s, thanks though. I did try it anyways btw.
Getting the update.zip from a friend. its in the SD card but its not showing up in MTP so were trying to figure that out. once i have the zip ill try flashing it. if it doesnt work, itll get a octoplus jtag flash.
Well the update did not like the fact that this phone was missing the linker bin or the previous root because it fails when checking the current system. Looks like octoplus is the only way cause i'm an idiot.
Anyone know where i can send this to get it done? i thought some people on ebay did it but i cant find them.
I have same problem, no download mode, system corrupted and recovery is useless.

If it's a tmobile G3 (d851) you have no choice but send it to someone for an octoplus jtag service because the DIY jtag method doesn't work. Got mine done for $42 after shipping from an ebay service.

You have triggered the downgrade QFUSE. There is nothing you can do apart from trying to unbrick it like it was dead, but that's not guaranteed to work. You should have researched more before attempting this. My prototype doesn't have a QFUSE, so i am free to downgrade via TOT to kitkat or lollipop.

I second you on this. I just uninstalled MultiROM and got the secure booting error. Depending on the ROM you have, find a bumped kernel and flash it. Most of the kernels on XDA are pre-bumped unless the developer states so. Boot into recovery, tutorials on the internet, then flash the kernel and voila.
if you can use twrp or you're able to flash, use mr_bump.zip: https://mega.nz/#!DNwhRBrK!Ki6zIzXca0KjPShi6L2oaCYIr0CkmH8sEymEt-0Q3ys

=> download the last img file from: https://eu.dl.twrp.me/d855/
=> no download mode available so no possibility to flash manually twrp file from an LG Flash Tool
==> so setup an adb connexion to the phone, cp command to copy the img file on the sdcard or where you want
=> command: "flash recovery twrp-2.8.x.x-xxx.img" (https://www.xda-developers.com/how-to-install-twrp/
=> if it's as worked, you could reboot manually in twrp, make again the partitions if needed and flash any ROM.

Honor 7x with Lineage and TWRP, stuck in limbo

Hi all,
I installed TWRP on my Honor 7x, that went well.
Yesterday I decided to try to get Lineage working so:
- I installed EMUI 8, that went pretty smooth
- I installed Lineage OS 15.1. (without GApps)
- I flashed TWRP.
The issue I have now is that:
1) I can't install any APK in Lineage. Probably needs a factory reset/dalvik cache wipe.
2) I can't boot into TWRP. It stays stuck on the splash screen forever. This also means I can't install OpenGapps, SuperUser access (afaik), or anything else that requires root.
3) The bootloader is saying "FRP: Locked", which means I can't flash a new TWRP or a different ROM. When I try it fails with "command not allowed"
3) "fastboot oem unlock" fails saying I need to enable it in the developer options, but it's grayed out in the developer options because it's already unlocked.
4) I wanted to try the "dload" method but I can't find a good explanation on how to do it, and Huawei recently took all their downloads down, which means I can't find any UPDATE.app even if I knew how.
5) The other solution that *might* work is using "fastboot oem frp-unlock", but I need an unlock code for that (I assume the same one that you request for an OEM unlock from Huawei), and Huawei closed down the site that generated the codes.
So I'm stuck in a weird limbo where I can't move forward (install Gapps and use my phone as normal) nor backwards (go back to EMUI8).
Does anyone have any idea how I can fix this situation?

small chance you enable root from developer options. (i think it will be adb only)
if so , maybe can use adb shell and "dd" to write recovery to correct partition.
problem is many of the available twrp do not boot on custom rom .
example code. (if you do wrong , it may be bad)
Code:
dd if=/ext_sdcard/twrp_Recovery_ramdisk.img of=/dev/block/mmcblk0p32
It seems like I'm allowed to use dd in ADB shell, but before I run it, what do you mean by " problem is many of the available twrp do not boot on custom rom . "? I thought recovery was independent of the ROM? And does it mean flashing twrp like that could brick my phone?

At this point you should have access to fastboot though, right? I'd try a different TWRP instead. Perhaps try this one: https://drive.google.com/file/d/1ZYo7Ndte3vlLcUSadD6jIgfBi1oxa0Pb/view?usp=drivesdk
Just to clarify, it gets stuck on TWRP splash screen. When I turn off the phone, it immediately boots up again into TWRP. I tried getting into fastboot mode with all kinds of combinations of button presses, but no luck. Not even Volume Up + USB cable works

This is because after the frp unlock, it needed to see a factory reset, and it usually needs to be done with stock recvery.
So will have to wait till battery is dead and and plug in usb while holding volume button. Should then load to fastboot. Where it is best to flash stock recovery to clear the recovery bootloop. The bootloop is do to the fact yo unlocked frp and now phone needs to wipe/data

Sorry, only saw your answer after sending my other reply. In theory I should have access to fastboot mode. However, everytime I start up I get into TWRP, which doesn't work. I tried Volume up, volume down, both, with and without power button, with and without cable, and no dice.

i just took mine apart and discconected the battery and still no luck that program deleted my fastboot
Please can you tell me the process to install twrp I have the L24
I waited all the way till the battery drained, stuck in the USB, and it booted to ROM! Sadly it immediately shut off again because the battery is dead (even with keeping the USB in). I'm going to keep trying though.
I can't get into fastboot mode. I can get into the ROM by letting the battery drain completely on the TWRP splashscreen, and then sticking in the USB cable. However, no button combination or "adb reboot bootloader" or rebooting to bootloader from the ROM brings me to the bootloader. I wonder if it's still there. Any ideas?

Seems to be a f-up situation either way.
You have adb DD available, found out before.
Don't know if maybe flashing stock recovery is good idea at this point.
I think fastboot.img can be flashed with DD too, but don't try till someone can confirm.
If flash stock recovery clears the loops, maybe best to do full-ota manual flashing.
I managed to get an UPDATE.APP file and extract fastboot.img from it, as well as all the other .img files. If someone can tell me what to flash and how (with dd), I think Im set.

Fastboot.img is the large part the bootloader. If flashing it goes bad, might be dead phone after, just rember that.
Will add a list of partition names and command s for you soon.
here is a list of oreo partitions and there /dev/blk/** number
and here is an example of code to save images with dd assuming you put the images on your extrnal-sdcard in folder called oreo-images
Code:
dd if=/dev/block/mmcblk0p5 of=/mnt/ext_sdcard/oreo-images/fastboot.img
Do that save first and compare the md5 of the file from update.app to this file.
or just check the md5 before making the copy
Code:
adb shell md5sum /dev/block/mmcblk0p5
If you are conviced you need to flash the images, here is example of writing the image assuming files are in sdcard folder oreo-update-images
Code:
dd if=/mnt/ext_sdcard/oreoupdate-images/fastboot.img of=/dev/block/mmcblk0p5
As I have said, this might be bad advise , I have not done fastboot.img flashing before. But on other devices it is same as lk.img or uboot.img, There is danger in flashing it incorrectly. That is why my suggestion was to flash no-check-recovery and do manael update with "echo -update_package" commands.
Along with the statement that fastboot.img is similar to lk.img or uboot.img on other phones, Your fastboot cannot be gone. because phone boots.
but do let us know how it goes.
I agree it would be better to flash recovery if possible. I assume I need the NoCheck-Recovery image from this thread? https://forum.xda-developers.com/honor-7x/how-to/manual-update-to-oreo-beta-emui-8-bnd-t3767044
And what partition do I have to flash it to? I'm guessing either /dev/block/mmcblk0p28 (erecovery ramdisk) or /dev/block/mmcblk0p32 (recovery ramdisk)? I'm not sure what the difference is between erecovery and normal recovery.
(didn't flash fastboot yet, wanted to see if recovery was doable).

To recovery_ramdisk. 32
What about check md5 of fastboot partition, that will be helpful to know if it did get wiped out.?
Hmm seems like I'm not allowed to use dd after all:
HWBND-H:/ $ dd if=/storage/7C96-7E17/BND-RECOVERY-NoCheck.img of=/dev/block/mmcblk0p32
dd: /dev/block/mmcblk0p32: Permission denied
And here I was thinking I was close to solving it...
Also can't run md5sum on the fastboot partition, since that needs root as well.
