[Q] [HELP NEEDED] Desire HD IMEI no change - Desire HD Q&A, Help & Troubleshooting

Hi,
I had a bricked Desire HD on which I gave for JTAG (restoring hboot). However, after the JTAGging process, my mobile signals had gone and I noticed that the IMEI number was different on the firmware from the one written on the mobile box and the back of my phone, is there any way to repair restore it? I will be very thankful

Hmmmmm..... In order to do such things, you have to put your device in HTC DIAGNOSTICS MODE, when the device is put in this mode. Another device is enabled in the DHD so that when its connected to a pc, the pc also recognizes the phone as HTC DIAGNOSTIC INTERFACE.
If you are able to archieve this, then you can modify your IMEI with QPST or CDMA WORKSHOP.

What rom are you using now?

]Now, the annoying part is, To put the DHD in DIAG MODE.
I searched and searched but couldnt find the command. So i went over to this thread http://forum.xda-developers.com/showthread.php?t=1626638
and found some DIAG codes but they were for samsung. I still tried and tried and was able to enable DIAG mode with this command
Code:
adb shell
su
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on
After entering this, a new device pops up in device manager but QPST is unable to communicate with the device.
It seems i have to enable other stuffs.
And thats where i got stuck. But now that you guys are also in this mess, we could create a thread in the General Xda thread asking for how to completely enable DIAG on HTC Devices

Go here and download the diag drivers for htc.
http://www.cdmasolutions.com/drivers.html
I have got one or two things to do so you can try your hands. Once you have installed ur drivers and QPST and entered the command from adb, open QPST configuration. If you see an open port with the inscription no phone, then you are stuck but if you see an open port with phone then you could be getting your phone working any moment from now.
Note if your phone shows up correctly, becareful of what you do with QPST. or you could brick your device.
Got to go...seeya later.

[Q] Received Ebay Phone, am I screwed?

Ok, I bought a galaxy nexus SCH i515 off ebay. The phone was listed as verizon, all the information behind the battery came up as sch i515. However when I powered it on. The phone said activate samsung account. The phone matches verizon info on the back. I contacted verizon and they said most likely the phone was rooted and that the phone could not be switched back even after a hard reset (which i did). I have wifi so used that to get on play store and downloaded rootchecker.... it says phone is not rooted.. (did original owner just unroot phone) am I screwed or is there anything I can do to get verizon able to activate it?
1) wrong section
2) follow this: http://forum.xda-developers.com/showthread.php?t=1626895
after step 2, check in the phone status menu for the model number.
So i'm a noob and after running through all this I can still (and verizon saying that the imei number wasn't in their database) make this work with verizon... i dont want to get this into a boot loop or fry this thing.. sorry for bugging out... I just want to know if this will officially work... again my phone was verizon and was switched to a sprint phone (upon powering up it asked for sprint activation.)

I appreciate your quick informative answer but if i've already called verizon and they have informed me that the imei is not in their data base.... if i do all these steps and flash back to complete stock the imei still will not be in there data base correct? I mean I'm still stuck on this.... if I need to start asking somewhere else please let me know. Thanks

fastboot and adb are 2 completely different modes, and the commands are not interchangeable. usb debugging has nothing to do with fastboot whatsoever

Just to make sure. You are in the bootloader on the phone and you are typing in the Fastboot devices and then OEM unlock command in Windows cmd? Try a different set of drivers. Uninstall the ones you have now and click the link below. Install those and do the "fastboot devices" command again. The naked divers seem to give people the least amount of problems.

as is strewn throughout these forums....ADB and FASTBOOT use different drivers. just because you have adb working doesnt mean that fastboot is setup properly

Yeah.
I can recall also reading something some time ago about making your SD Card(External) the bootable one and then fixing the "internal" from there but I'm not sure if that will even work either, was for another device as well.
I don't think a lot of developers/"hackers" on here sat down trying to figure out solutions to a problem that isn't so frequent on this device. I mean, who would flash a LG "anything" on an HTC...
Just wondered if it might work out seeing as it at least "detects" that much from the phone. It's a type of Qualcomm recovery mode isn't it, QHUSB-etc etc
Figured that maybe it is in a "semi" on condition already, it's just that you can't do anything with it. But if it's completely broke then might as well take it into service center for repair. Don't know what you're gonna tell them though @escoda
Yep. From what i know on the htc one x, once you turn off the phone completely (no hibernation mode) and you plug it in the pc it goes automatically to a adb hibernation mode. That's why its in the device manager. So it reads the device but can't respond correctly. But to get a step ahead it's very necessary to turn the device on.
@escoda its not completely bricked yet. Just go to ubuntu and follow the guide mentioned from Brendm14. Like he also said you only need to download then those files for the htc one m8. Most qualcomm devices have everything on the same partition but you could probably examine or the bootloader and the other required stuff are the same partition number as in the guide. If so then you still just need to download the htc files and do it the same.
I dont know where you can get the htc files since I am/was an LG user.

Those files are present on any firmware.zip for the appropriate phone model.
Flashing just a wrong kernel would not do that. Something must have happened that messed with the bootloader.

Is your phone in Qualcomm QHSUSB__BULK mode?
If yes I recently got this problem on my D855 after getting an OTA update, it hardbricked, it will need to be boot repaired, the owner of the board diagnostics software is in the thread you got your software from, he restricted his software so that it will give the said error.
He charges 50 USD for repairing boot, I returned my phone to the seller, you should try the software in offline mode, i-e disconnect from the internet before launching the application, if it works then tell us, if not then probably the best option will be to ask the owner of this software for access.

The drivers should work, other people said they do. What probably you are not able to do is put the phone in Diagnostic mode.
Maybe with with, but it is not sure
Is this the way to put the phone in Diagnostic mode ?

I'm sorry I'm poor in English.
I set my phone cm13 and type this one " setprop sys.usb.config diag,adb"
If cm13 is the problem, I'll try with oxygen rom.

NO is not,
http://forum.xda-developers.com/showpost.php?p=67470602&postcount=2
If you switch a device into a hybrid mode like "diag,adb" it will dish out a new custom product id over the usb interface, one that combines both devices into one new one.
There are however no fitting diag drivers that match that product id.
If you want diag to work properly, switch your phone into single-diag mode by executing setprop sys.usb.config diag via a rooted terminal emulator from the phone itself, rather than doing it via an adb shell from a computer.
This will result in the proper diag product id being reported to your computer, allowing you to install the right driver.
As for the driver download, a simple google search will yield you the results.
Just search for "Qualcomm Diag Driver x64".
Edit: Oh one more thing... last time I checked I couldn't find a properly signed Diag driver for 64bit systems...
You will probably have to boot your computer smashing the F8 key repeatedly, and picking "disable driver signature enforcement" from the boot menu to temporarily disable the driver signature check, allowing you to install and use the Diag driver.

Bricked H815 no bootloader no download modus

Hi,
I got a G4 H815 from a friend. He tried to install a custom firmware and killed the G4.
I see the G4 in the device manager as a qualcomm HS-USB QDloader 9008, but nothing more.
With the LGFlash Tool: It will transfer the files, but after 8 seconds it fails caus of missing download mode.
With LGUP, after I changed the driver to an LG USB COM Port, it connected but at Model: Unknown model. And stopped
I think, I have to install first a bootloader on the device, but how?
Someone can help pls?

Hi,
I got a G4 H815 from a friend. He tried to install a custom firmware and killed the G4.
I see the G4 in the device manager as a qualcomm HS-USB QDloader 9008, but nothing more.
With the LGFlash Tool: It will transfer the files, but after 8 seconds it fails caus of missing download modus.

1) Did you put your phone in download mode before using LGUP?
2) You can install custom recovery using adb commands if your bootloader is unlocked.

The problem is: It´s dead!
no bootloader, no download mode, no recovery...
The phone is clean.
That´s the big issue.
There is one solution I read with a dump/bin file here at xda...
But I don´t know if it is the right file for the 815, it says yes but...
My plan is, to dump a file via SD-Card to activate the download mode. But I need someone who can say to me " Thats the way, and these are the files you need to"
