[Q] Help: qualcomm hd-usb qdloader 9008

Today I though let's get cm9 on my nice nitro.
What did I do:
Rooted and installed cwm bytes version
installed custom 0.3 of kernelpanic
Today I installed cmw from the market and installed the new version.
Then I installed the cm9 but it stated that the sd card was not mounted (sdcard pointer wasn't right or something).
I tried all kind of things, but cmw would not work.
So I tried to install cwm bytes version again
[HOW TO]Install ClockworkMod Recovery The easy way
and did: dd if=/dev/block/mmcblk0p6 of=/sdcard/mmcblk0p6.backup bs=4096 and dd if=/sdcard/_ExternalSD/recovery.img of=/dev/block/mmcblk0p6 bs=4096
Then I did a restart
Nothing happened, nothing at all
No screen no download mode
When I connected it to the pc, it has some usb drivers:
qualcomm hs-usb qdloader 9008
Now what?
I am from holland, so getting it back to the US is not a good option, I also don't have an email address from the seller (ebay). I already send him an ebay message, but I don't know if he is still member or something (2 months ago I bought it).
Does someone has a solution?
The name of the windows driver is Qualcomm HS-USB Qdloader 9008

Oh ****, it looks like you flashed CWM to the wrong partition. Um, I think you're going to have to try to unbrick using a .kdz, possibly the SU640 one. My unbricking guide is out of date (my fault, but real life has kept me busy), but all the information you will need is in this thread somewhere. Please read all the posts, particularly ones toward the end of the thread that will tell you how to edit your hosts file and set up a server so that the kdz update tool will let you flash the .kdz file.
Edit, I forgot to mention this will only work if you are able to get into Download Mode. Please confirm if this is the case.

I doubt it. p6 is the SBL (secondary bootloader), I think emergency mode depends on it.

I cannot get into download mode, I only see ethe qualcomm driver in windows, nothing else. No screen, no nothing.

Your situation is not good. Your best bet at this point is probably getting it repaired by LG/AT&T unless aremcee or someone more knowledgeable than myself can help you rescue it somehow. Whoever's post you followed that told you to flash to p6 was horribly, horribly misguided. Unfortunately, as you know now, flashing roms the manual way can be really dangerous if you overwrite the incorrect partition. I'm sorry it ended the way it did for you...

Yeah I think I screwed up... I just wanted to get ICS on the phone, anyway.
How can I repair it? My seller does not respond, is there a possibility that someone else can get it to at&t for repairs? or wouldn't that be possible?

maybe ask someone to pull (dd if=) their sbl p6 and you could try to overwrite whatever is on yours now.
worth a shot, I know on samsung phones if this happens you need a .pit files, which will help repartition. I dont know if LG has a similar option.

what software do I have to use to get the new p6 on the phone, for samsung there is ODIN, but for lg?

See, that's the thing, the closest thing we have to Odin is the KDZ update tool and as far as I know they both kind of have a caveat of needing the emergency/download mode intact. I really don't know if there is any way to rescue your device without physically getting in it and reflashing, which most people are not equipped to do.

adb probably is no go as well huh? or you would see android/LG driver...
if this was another device I may have more ideas, but I have no exp. with LG.
{tell them you just hooked it up to Itunes to sync your playlist....an it went all weird.. hahahah}
Not sure how releveant this is but I think one of the Qualcomm Phone tools may have an option for raw memory read & raw memory write.
For example READ_MEM from address 0x0200000 to 0x0250000 (from a device with a working sbl of course) and dump it to a file.
Then WRITE_MEM and cross your fingers. Very dangerous and would take some research to find the sbl memory address.
A long shot more geared towards the technically inclined.

Is there someone who can make my phone work again? I can pay you for it, otherwise I will sell the phone, broken as it is.
My seller won't respond, so I have nowhere to go. If someone want to help me, you are welcome.

You know, you could always ship it off to LG. I sent them mine after having the EXACT same problem, and they fixed it and it's on its way home right now!

Did you have to pay for this? Do you have the contact info? Thanks.

Don't have to pay, they can't turn it on, so how would they know ? Just go to their website and fill out a warranty support form.

i have the same issue with my lg connect ms 840.
would you mind to share how to unbrick it.
i only have riff box here
tyvm

For the jtags you first need to check if the cpu is supported. If it is, all you have to do is disassemble the device, locate the pins solder up and go for it. Some other model may have same pinout. Just make sure it is same layout, and check if vref and gnd are in the same place. If successful connection is achieve, you just need converted files from box support. Send them full stock rom for your model. If cpu is not supported, it will take longer and will be harder. Get into the forum support of either, medusa and riff. For the OP, see if you can send it to LG but if you can't, someone at forum that lives nearby you could help you. Only solution afaik is jtag.

[Q] PLEASE HELP! LG G3 Bricked?

So, on Thursday I picked up an LG G3 from Verizon. I was absolutely loving it. But like most people, I wanted custom ROM's and roots and all the fun stuff you can do with android phones. I rooted my device the day I got it with IORoot. Everything is working fine at this point.
After this, i wanted a custom ROM. I found that there wasn't many for my specific model, but i did see the Sphinx G3 Neo ROM. I payed no attention to what variant it was for and loaded it up on my phone. At first, everything was working perfectly and it was butter smooth. But then I noticed whatever messaging app I tried to use would not work. I did a factory reset and then did the same process to load Sphinx on my G3. This time, messages were working, however, mobile data was not. I finally had enough of this and decided to return to the stock ROM. I found all of the stock files and was attempting to use the TOT method. I put the phone in download mode (which it won't come out of btw) and tried to start flashing. I then realized what I had done and saw that my device was reading something like D855. So when I downloaded the Verizon files it wont work. But will I be able to fix this? Have any of you had this problem before? This phone is brand new and I cannot replace it at this point. I would really appreciate it if someone could help me out.

Hi,
So sad to hear that. Have you tried TOT files from this thread?
I hope your imei is intact.

I don't it is bricked per say. I do believe that the only way to solve the problem will be to do as you were trying, return it to stock with .tot files, you just need to find some information which I did see in the threads somewhere with regards to getting out of download mode.
Once you get that done and flash back to stock, then you can root again, I would suggest using Stump root, and the unlock the bootloader with Bump, and this would be a good time to make a backup with the recovery TWRP.
Be calm and read as much as possible, I hope you sort it out. Good luck.

Nah, just gotta pay more attention to what I'm doing. Plus, bump just came out.

I take 6 hours to find solution, must use another dll "LGUP_8974.dll"
This one let .tot file take control and don't check phone model, if someone have the same issues this can help

Nexus 5x stuck at google screen [Potentially Hard-bricked]

*** The issue is resolved!!! Thanks to xda, the solution is provided in the link in the comments.***
Couple of days ago I got this OTA notification that Android 7.1 preview is available for update. As my phone is rooted I started the manual update procedure. After the flashing was finished, I restarted the phone and then I saw it was stuck at the Google screen. Just stuck, no response. Seemed unusual to me.
Let me tell you that I have been modding my Nexus 5 for about two years. I am familiar with most of the tweaks that can be done to a Nexus device. Nexus 5 served me amazingly. I bought Nexus 5x 3 months ago.
So, after it was stuck I restarted. Still stuck. I will tell you step by step what I did then:
1. Flashed the OS 7.1 again (I dunno why, the flash.all script doesn't work for me, so I always do that manually) - result is the same.
2. Last October update (NBD90W) was available in the folder so I flashed that - same result.
3. I downloaded the previous one (NRD90S) and flashed that - same result.
4. I locked the phone and unlocked again to erase everything (not sure if that's a good idea), then flashed the OS again - same result.
5. Then I tried LGUP and the tot files to give it the factory version. LGUP detects the phone, started installing. When the installation is finished and the phone restarted - same result.
6. Now that I gave it the factory version the phone got locked!
7. I searched google for hours but couldn't find a way to unlock it as the OS is not booting and I cannot turn USB debugging on!
8. Then I tried the default recovery mode (Android recovery, from the recovery screen Power + volume up) as it doesn't require unlocking the device. Wiped the cache and restarted - same result.
9. My phone is detected by the pc and ADB. So, I wiped everything and tried ADB sideload and get this error E: footer is wrong
10. I tried Nexus root toolkit. It detects the phone in fastboot mode, then restarts it and then it again is stuck on the Google screen.
I am extremely depressed!
I am from Bangladesh and there is no authorized LG servicing center here. So, I can't ask for their help.
All that I did over the past two years was the awesome threads of xdadevelopers. So, a big thumbs up for you guys . :good:
I learnt from the web that phone can be hard bricked if a wrong bootloader is flashed. That's impossible for me as I always remove the factory image extracted files after flashing is done from the ADB>platform-tools folder.
Now, is the phone hard-bricked? If it is, what to do with it? Will replacing the motherboard get my phone back? Any kind of suggestion will be very much appreciated.

Bummer. This sounds a lot like what I just posted here: http://forum.xda-developers.com/nexus-5x/help/req-help-bootloop-7-1-1-beta-ota-enter-t3486957

Well, I don't get bootloops, my phone is just stuck at the Google screen and I can enter recovery mode (lying Android with red exclamation mark), from there I can enter Android recovery mode, where ADB sideload is available.

Please say something about replacing the motherboard. It's very very pricey, so I want to be sure -_-

sounds like its hardware problem, contact seller to replace it. if not going to happen, then buy a new phone from a company that does have a dealer in your country to warrant. aside of camera, the specs of other phones at this price range are better

That thought is also roaming around my head, still Nexus is Nexus!

What's the price going for the 5X over there? It's as low as $280 here in the US which is easy better then it's original.

Try the tutorial here. It's little bit different from the original thread ,
as @bardhi92 said, THE MAIN DIFFERENCE HERE IS THAT AFTER I FLASHED THE .TOT FILE, I BOOTED MY PHONE INTO BOOTLOADER AND DID AN ADB SIDELOAD OF THIS OTA.ZIP
Well, for my case, eventually I successfully bring my N5X alive. The tricky part is to enter Android System Recovery (hold Power + Volume Up) after flashing TOT.

A warranty is a warranty, it doesn't matter what country you're in or where the repair place is. People in Canada send stuff to the USA for warranty issues all the time. I'd get on the phone with LG until I heard what I wanted, but I'm a stubborn old goat lol.

Completely Stumped after LG send me the "repaired" phone

Hi All,
I sent my Nexus 5x for repair and they gave me an option of "reparing ($77)" and refurbishing" $190".
I'm comfortable with ADB, fastboot and all that jazz so I thought I'll just get it repaired.
Well , I turn on the phone and I greeted with the go to go.c/ABH page
Then it loads some "miniOS" and ends in an all orange screen saying WARNING Not supported QEM = 0
And that is where it is stuck.
NEVER seen this before in my life.
So I get into boot loader.
FAST boot is locked the OEM unlock command doesn't work - FAILED (remote: oem unlock is not allowed)
Next thing I try.
Open recovery, start adb, get myself the latest OTA from google side, side load it.
SIGNATURE FAILED.
I tried EVERY single OTA file on the site and all failed.
So I'm stumped... Any advice or insight is greatly appreciated.

These LG problems are not 1 in every 10,000 handsets there selling dodgy phone's knowingly and expecting the customers to sit by and get ripped off they have just lost a lawsuit for the g4 and v10 handsets and instead of everyone allowing it we need to jointly stand together from all over the world and do something collectively and kick up a stink until we make enough noise they end up in court again if they don't give us refunds. If you're not interested in this it's going to be harder for the people who want to get something done about it

Just flash kdz or tot

KDZ is LG Phone firmware image
Can be flash by lg flash tool.
Usually use in LG phone that lg published own firmware version.
In Nexus Google usually published firmware so as you can see flash via fastboot.
TOT is lg factory firmware image

Ok so here is where I'm stuck. Looking for a KDZ file.
I don't see anything for 5X. Am I supposed to use the G2 one or something else?

Ok here is the thread I'm following
https://forum.xda-developers.com/nexus-5x/help/req-help-to-unbrick-t3251740
I'm going to be using the 32GB TOT and then reverting back to stock 16gb Google OTA.
THIS WORKED OUT WELL. THANK YOU all for help.

[CLOSED][ANY BL locked G4]need testers [follow the new thread!]

First of all: Do not continue if you don't know what a hard brick is!!!
so well its that simple: Either my method will work or fail.
Please follow the story here now:
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
Previously this was the OP:
if not: this could result in a completely unusable device (soft or even hard bricks are possible)
If it works: you could unlock your phone in fastboot with a simple command - no unlock key is required (but even when the method WORKS its possible that this produces other issues. we can not know all impacts yet)
So AGAIN
The whole process is dangerous but the chance to get an unlocked phone would be worth it - maybe. It depends on you.
I can't test it atm by myself because my device is on its way to LG (due to another issue)..
My method does not modify something within the bootloader like others tried already - because this would definitively break the boot chain.
I will not release any details to the public until there is anything proofed or verified. The whole process is very risky and as said: I have currently no device to test it.
The only thing which is proofed is the theory. It should work as long as nothing unpredictable happens: As long as we do not own the complete sources of all parts of the boot chain there is still a risk.
Keeping the details under the hood is not to make things mysterious. It's just for safety reasons until I can proof anything.
If you still ask for details here or by PM they will not be answered.
If you not able to join an IRC channel you better leave it directly.
I'm not 24/7 online but usually from Mo-Fr for sure so it is important to wait for answers while in the IRC because depending on your timezone this can take some hours (hey I have to sleep somewhen!)
Once I have my device back from LG I can test the method by myself on a H815 EUR version. It doesn't matters that this can be officially unlocked though. The risks are the same.
So if you're too scared for the moment just wait about 2 weeks or so and then I can tell if it worked on my device at least.
.... and if you do not want to wait: Follow me into the IRC for instructions
If you never were in touch with IRC before here are some client examples for you:
PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
The IRC channel is: #Carbon-user
The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)
.

Super excited about the possible G4 unlock! Wish I could test it but my phone is my daily driver and my source of internet at home so if it breaks, I'm screwed for my online classes. Thanks for your hard work as always!

It happened to mine 818p too, you need to disasseble it and short two pins on the motherboard while starting it. (They are in the upper left corner on the MB.) This page (forum.gsmhosting.com/vbb/f779/unbrick-lg-g4-brick-hs-usb-qdloader-9008-without-box-2211744/) has the entire process explained but I was unable to sucessfully use the QFIL app, it didnt recover anything, at least the phone was seen on PC as the 9008 serial port. I hope it helps
P.S: Sorry for my bad english.

i hope you get it going man. so lots of users can enjoy this device like it should be.. youll be saving LG G4.. am glad that what i mentioned you got your brain thinking and finding ways i beleive this all was what i mention on fish. good luck to all of you.:fingers-crossed:

Oh, sorry, I thought it was bricked, not physically broken.

Yea i still used it for about 6 months. Put the fish to her. Even still vred with thr cracked screen. Like i said. Went to check the time and nothin. So im assuming shes dead. Ive done got a g5.no root and no twrp. Yea. Just the way i like it. I know i know. If i wanted root i shoulda bought an unlockable model. But i take what i can get cheap. Bought my sprint g5 for 25 bucks at a police auction

Hi, I have the model H815T but... now it Hard Bricked haha. Anyway, I can boot it like LS991 model (with QFIL), and Download Mode it's working too. So... is useful for your method?

steadfasterX said:
First of all: Do not continue if you don't know what a hard brick is!!!
so well its that simple: Either my method will work or fail.
if not: this could result in a completely unusable device (soft or even hard bricks are possible)
If it works: you could unlock your phone in fastboot with a simple command - no unlock key is required (but even when the method WORKS its possible that this produces other issues. we can not know all impacts yet)
So AGAIN
The whole process is dangerous but the chance to get an unlocked phone would be worth it - maybe. It depends on you.
I can't test it atm by myself because my device is on its way to LG (due to another issue)..
My method does not modify something within the bootloader like others tried already - because this would definitively break the boot chain.
I will not release any details to the public until there is anything proofed or verified. The whole process is very risky and as said: I have currently no device to test it.
The only thing which is proofed is the theory. It should work as long as nothing unpredictable happens: As long as we do not own the complete sources of all parts of the boot chain there is still a risk.
Keeping the details under the hood is not to make things mysterious. It's just for safety reasons until I can proof anything.
If you still ask for details here or by PM they will not be answered.
If you not able to join an IRC channel you better leave it directly.
I'm not 24/7 online but usually from Mo-Fr for sure so it is important to wait for answers while in the IRC because depending on your timezone this can take some hours (hey I have to sleep somewhen!)
Once I have my device back from LG I can test the method by myself on a H815 EUR version. It doesn't matters that this can be officially unlocked though. The risks are the same.
So if you're too scared for the moment just wait about 2 weeks or so and then I can tell if it worked on my device at least.
.... and if you do not want to wait: Follow me into the IRC for instructions
If you never were in touch with IRC before here are some client examples for you:
PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
The IRC channel is: #Carbon-user
The IRC server network is: freenode
Once you're connected with the IRC network I need this from you:
your phone model
the currently installed EXACT firmware (link to the used KDZ would be most helpful. If you have none check the phone details and e.g. make screenshots)

Now out of curiosity would a bootlooped g4 work. Most of em boot into dl mode and if it bricks dl modde youd know rite away anyways right?

Qcom 9008 mode? It could be fixed afaik.. You can also try the sdcard boot method for this kind of brick. you should try that first in any case..
I'm not sure if my method will work in that kind of brick mode you are in but if you nevertheless want to test you need Linux / best is using FWUL because it has everything needed inside.
Once ready went to IRC on Mo-Fr and stay until Im there.

it depends. When it stays in download mode without looping.. yes - maybe!
I need access to to the partitions which may work even in download mode via a special shell but it may requires MM and will not work for LL firmware (strange right? normally one would expect the other way around..).
That has to be tested though. On my device (locked H815) I had access but that may differ from other models.
Having root access makes things so much more easier
Testing if it would be possible on a bootlooping device would be simple:
You best use FWUL (recommended because here is all installed and working) or any other Linux with the LGLaf shell.
You would then connect while in download mode and you will have a shell like in adb.
I can guide you but again IRC is the best way to go here..
I'm searching since several days for such looping and even otherwise broken/defect devices but they all want to have a plenty of money for it (80-150 €!!)

Yes, QCOM 9008 mode. I can't flash the H815 image and make my G4 H815 again so, the only way to booting, it's flashing the LS991 image (and with Fastboot; I flashing every partition one by one).
I have Linux Mint whit adb/fastboot drivers, It's enough?

Hmm I can't help you unbricking. I just know that there are ways to do so. You need the correct drivers etc.. But well if you tried all this already we can try
Any Linux is ok as long as you can handle it
Havin TeamViewer installed may help too...
Well so if you like go to IRC Monday to Friday and we will see

Yes. today I have bad and good news.
First of all I had 1 single tester who was brave enough going the first approach I had. Unfortunately my first idea failed.
JL if you see this come back I said I can unbrick your device!!!
Ok so the good news are: I'm able to give you a near unlocked experience with all the things you love like installing custom kernel, recovery and ROM. Without actually unlocking!!! It's all tested on a h815 device which was never unlocked !
Near unlocked means it will behave like an unlocked device without actually unlocking the bootloader. Or to say it in other words: The boot chain verification is ignored.
The bad news: the process is not cleaned out yet but it requires one thing for sure: it will convert your whole device bootloader stack. The basic idea is to replace the whole bootloader stack with a modified one which allows all the mentioned things.
That way is very risky and I HARD bricked my device over 30 times until getting to the finally working result.
It also means that once your device is converted there is no way back atm. Flashing an original kdz will BRICK your device in 9008 mode! Not that bad because you can recover at any time but that's one thing you have to have in mind. It may never be a h811, h812..... whatever again. Until we find a corresponding and working bootloader replacement which may never happen. So no LG up or LG flash tools anymore! Instead you will have the qfil tool.
Again I know no way back to original state so warranty will be very very likely refused once you do this. Ok there is a way to blank out all partitions just for the case you need to send it really back. This should delete then most traces of this hack but no guarantees.
Besides this I don't know if there are any issues in functionality after doing all this. I havent made any tests for this yet. That includes phone calls, WiFi etc. I just checked booting ROM, booting TWRP, flashing supersu, getting root.
I will upload a video asap to show you the current result.
I need to test things further and of course I need testers with other devices. Again that process is risky and even if it worked for me it may not work for you (very unlikely but who knows). Manually forcing the 9008 is very easy and it may be required to do so. This may requires opening the device (I think it will work even without but I need testers.. ) so if you want to test... See you in the IRC.
If all this is working and verified by others I will provide the whole story ofc!
....can't believe that all these above took me 5 days in full time of work. And for what? I mean I do not need it because I can unlock my device OFFICIALLY..
BUT it was all for educational learning. I learned really a LOT of android and qcom during all these hours ...
Ok but Now I need some couple of hours of sleep
See u on the other site..

so........what now ? i have a F500k device . and i'm willing to test your method . but i'm not sure what you are saying here. ( i didn't understand a single word) . but if it means that i can't flash official KDZ or can't use LGUP....no problem to me.
just share to me how i'll do it and if i hardbrick how i'll restore it. thats all.
