[Nokia Lumia 520 Questions & Answers] angstdasein:
Just a heads up, if you give the windows phone subreddit a quick read you'll notice we are not the only people to have this issue. Apparently several other people trying to roll back their phone have it completely bricked and in the QHSUSB_DLOAD situation.

I don't think MS can do anything about it, since the boot crapped out you either need to buy the tools or get it repaired by someone having them, but at least it proves there is some kind of problem with rolling back from the preview.

[Nokia Lumia 520 Questions & Answers] angstdasein:
After a bit of reading more and more people are reporting this, so please put your own experience on this technet thread, it's a good idea to centralize reports where Microsoft can see it.

I can't link it here (don't have the permission to post links yet) but it's the first result by typing "Lumia 620 bricked during rollback procedure: recovery possible?" in google.

The solution seems to do a JTAG... Bad news for normal people ::crying:
[Nokia Lumia 520 Questions & Answers] GeorgeLeonte:
Bricked Nokia Lumia

Actually, the red screen means that the phone went into its UEFI MODE.

In UEFI MODE your phone could be restored as normal by a HARD RESET (see key combo).

If you have a hard luck, your phone will automatically start in Flashing Mode (IMO(0x0000001)) which only works on the downloading procedure when on Rolling back.

The RollBack program has to put your phone in Flashing Mode in order to gain access to it's microchip.

Well the app itself knows what to do, but something failed.

In this point, you disconnected the phone and tried all you've known to power it on. Meanwhile the app deleted it's cache file, it no longer knows why your phone is in that state and your PC will get it as QHSUSB_DLOAD which is a Side_Load driver for Qualcomm Enabled Phones.

At this point, RIFF JTAG is the only solution as your BOOTLOADER is dead.

Good thing? It could be fixed by any GSM Service and the price could be small.

DO NOT try any Nokia Care / Refurbish / Restore app. All of them are created to work with a phone that has it's bootloader working.

None of them will cooperate to reflash it.

Even if you manage to reflash the OS, you don't have a BIOS / BootLoader....

Hopefully, Microsoft will create a tool to fix this as it only occurs when Rolling Back from Windows 10 Tech. Prev. and 8.1 to 8.

But until that, your phone is dead.

As someone said, eMMC only works if you have required files. As for Lumia 520 you can't get them.

Sorry if i post here but i have a similar Problem. I used reset my device Option in info in Windows phone 10 in my lumia 1020. now my phone boots and after that it has no menu. Only the lockscreen and the colume menu. Nothing else. What should i do now. Any suggestions ? Restore it with lumia/Windows phone recovery tool ?
[Nokia Lumia 520 Questions & Answers] GeorgeLeonte:
Qhsusb_dload

When I said "Even if you manage to reflash the OS, you don't have a BIOS / BootLoader.... " I meant QHSUSB_DLOAD state.

When on QHSUSB_DLOAD, your Qualcomm MicroChip have almost all it's functions stopped and waits for a Flash File.

*Default Timeout is 8 secs.

---------- Post added at 07:40 AM ---------- Previous post was at 07:35 AM ----------

UEFI MODE (red screen) doesn't means that your phone is soft-bricked. It is just like opening BIOS on your PC.

You can manage to get out from UEFI MODE by using thor2 as you said but you can still fire an update from Nokia Care / Recovery tools.

A Lumia in UEFI MODE is seen by Recovery tool as a UEFI MODE PHONE so you can flash it.

Actually QHSUSB_DLOAD is a bad sign. I managed to fix my own using some hard coding on a eMMC bay.

---------- Post added at 07:44 AM ---------- Previous post was at 07:40 AM ----------

Use HARD RESET Key Combo. Never use lumia/Windows phone recovery tool. These tools are still very buggy at Connection Manager part.

You have all the chances to get yourself a brick.
[Nokia Lumia 520 Questions & Answers] zapirkon:
Is there a solution for QHSUSB_DLOAD?

I got there after 3 times the recovery software stopped during downgrade

first two times it was <5% when failed

the third time it got to maybe 10% and then the screen was black...

I tried thor2, it lists something... but the connection times-out... so I am not sure it can work

I have the same problem with my Lumia 720. Not even powering on after rebooting it from the Red Nokia Screen. I tried Thor2 but it failed to communicate with the phone (obviously because it does not power up anymore).

Lumia 925 checking in. Same issue here. Used the Windows Phone Recovery Tool, failed midway through and now my phone has display and won't respond to any button combination and is detected as QHSUSB_DLOAD when connected to a computer. So many people with this issue and microsoft hasn't said jack. Years of tinkering with Android devices and never bricked one, yet Microsofts own tool bricked my Lumia. Gonna go check out some Android phones to replace my lumia. Maybe Microsoft will eventually issue a fix for this.

To those having the flashing process fail at whatever % using Thor2. Just run the command again, without rebooting your phone, it will continue. It worked for me at least.

[Nokia Lumia 520 Questions & Answers] mattwhite7102:
I bricked my lumia 520 through trial and error but i got the solution below ONLY IF YOU GOT THE QHSUSB_DLOAD MODE:

1. Paste this file directory in cmd.exe

C:/Program Files/Microsoft Care Suite/Windows Phone Recovery Tool

2. Now the code is:

Thor2 -mode emergency -hexfile C:/xxxx/xxxx/xxxx.hex -mbnfile C:/xxxxx/xxxxx/GPT0.bin -orig_gpt

Replace xxxxx with the corrosponding file directories leading to the file

Then it shouldnt take more than a few seconds

3. Then take out the battery, put it in the phone and hold the power button, you should feel a vibration and it boots automatcally in nokia flash mode

4. Then just flash the ffu onto the phone by inputting this and pressing enter:

Thor2 -mode uefiflash -ffu C:/xxxxx/xxxx.ffu

To generate GPT0.bin the code is:

Thor2 -mode ffureader C:/xxxxx/xxxxx.ffu -dump_gpt C:/xxxxx/xxxx

IMPORTANT: always dump the current ffu file flashed onto the phone otherwise it will not work

HTC has a program called Champions for employees of carrier retail stores. They are offering them a M9 at $299 off contract. Furthermore if they buy a M9 from the discount program they can trade it in for the next One at no extra charge with their "One for Life" program. I posted the screen shot from the email on my G+ page: https://plus.google.com/+PatrickHill/posts/Mr462GhpLbw

So if you work in a carrier store go sign up for Champions and get your M9 for only $299
[One (M9) General] Azoss:
is this us only?
[One (M9) General] ohmygaa:
My store wasn't listed, but it's a small mom and pop shop that IS an authorized T-Mo dealer. Hope I'm able to be considered and that it isn't closed to only those who work at the retail stores.

[One (M9) General] Kawaisa:
These deals are generally restricted to corporate retail stores by the phone manufacturers as they do actually verify that you're eligible before allowing you to make the purchase. Could be different for this deal but I'm assuming it's not.
[One (M9) General] pinguo777:
I am a member of HTC champions. there is a strict verification policy to ensure that you are a corporate retailer employee. The community is meant to help dealers learn about HTC and interact with other corporate employees.

Did you use your work email if you have one? Just wanted to make sure cuz I just used my personal email to sign up but I dont know if they use the corporate email to verify or anything (I have one if they need it). And would you mind saying how long it took for you to get verified?

I actually cut into one guy's sale at AT&T because he was telling this customer sh** that just was false and set him straight real fast.. haha
[One (M9) General] ultramegax:
Are we sure this is US only? I really hope not. I'm Canadian and my store was listed when I signed up... It even allows Canadian addresses (listing provinces and allowing postal codes, etc). I'd be deeply disappointed if we're left out of this. Does anyone know?
[One (M9) General] max53389:
Sorry for the long response time.

I pretty sure that you have to set it up through your work email. You just find your store in the list and I think you also get verified with your work email.

I'm not too sure how long it took to verify but on the discount page it mentioned that if you recently created an account, it could take up to 2-3 days to process if you just started as it's a different website that you buy from and separate from HTC Champions.

I set up HTC champions well over a year ago and kind of fuzzy on the exact details but use your work email for everything HTC and you will be fine.

Edit: Found this on the promo page

So that's the time you might have to wait and I honestly don't see this selling out quickly as it's not a very popular phone.
[One (M9) General] samven582:
Did anybody get a shipping notification?
[One (M9) General] graffixnyc:
Judging by the content of your post history and your impatience I would bet you're someone who doesn't work at a carrier store, who got into Champions, got an order in and are now waiting to see if they will actually ship it or if you will get busted and it be cancelled... If that's not the case I apologize but if that is the case (which I would think someone who worked at a carrier store would be more knowledgeable than the content and questions you've asked in your posts.. for example.. asking if the GS5's all had yellow screens or if it was just yours.. if you had worked in a carrier store you could have compared it to many others in stock or that you sold) then I hope you do get busted and the order doesn't ship. I didn't post this for people to take advantage.. I posted it for legit carrier employees who might not even know about the program... Again.. If I'm wrong I apologize.
[One (M9) General] samven582:
Bad day at work? Or you had a case of the Mondays? What ever it maybe and judging for your post and tone it looks like you're taking out your frustion on me. If you have a problem with I said you should PM me instead of trying to publicly humiliating me on XDA.

Now the reason why I ask is because I know someone who works at a ATT and was able to convice him to order one for me since he is part of HTC champion. Since you made this thread for people who work in retail carrier stores, I figured I would ask

Going through your post history you answered a similar question on how your HTC m9 screen was "green" and it was the resullt of glue? How did you know this? What is your evidence?
