[HD2 Android Q&A, Help & Troubleshooting and Genera] elny16:
HTC HD2 does not boot to cLK

Hi

I have run in just exactly same issue with my old HTC HD2. It is European GSM version. Hope some one has a fix for it.

Few years back I successfully flashed Android 2.2.x (dual-boot with Windows Mobile 6.5) and then little later installed v.2.3.7 NAND via cLK Recovery. The problem has occurred when I recently attempted to install JB.

Just as stuartgr, who started this thread, I tried the method described here:

1. Because earlier I tried MGKLDR method which also failed, I decided to try cLK. I started from scratch flashing WM6.5 ROM - I downloaded and unzipped "RUU_Leo_HTC_WWE_1.48.405.2_Radio_Signed_15.28.50.07U_2.05.51.05_2_Ship" file, renamed RUU_signed.nbh into leoimg.nbh, copied leoimg.nbh to clean formatted microSD card and successfully flashed this ROM into my phone. Rebooted my phone into WM6.5, followed prompts and completed WM6.5 initialization just to be sure my phone works, and it worked ok!

2. Next I followed the guide specified above exactly step-by-step:

- I flashed HSPL 2.08 with HD2 ToolKit 4.3.1 (success):

my phone shows now:

PB81100 HX-BC

SPL-2.08.HSPL 8G XE

0x05

CotullaHSPL 0x40

- wiped phone’s memory with Task 29 (success).

- at the repartition stage I chose cLK Repartition and then 300MB/5MB for system and cache sizes (thinking to install JB4.3 from

http://androidforum.tytung.com/nexushd2-jellybean-cm10-2-t78.html),

then I clicked Repartition button and completed successfully the process (image version CLK 1.4.0.1).

- I returned to HD2 ToolKit and selected “cLK Intall Recovery” option and clicked at the bottom left Install button, got warning message “There are two methods of installing cLK …” to which I clicked YES, CMD window came up welcoming me to cLK upgrade, as prompted I pressed “any key”, next in the same CMD window I got “Power it off, and hold power and back button till you see some characters on screen. Press any key to start.” When I removed buttery and tried to power on my phone holding back button the phone showed white screen with HTC logo and hang at this stage, it did not boot any further, I did not get black screen with “some white characters on it” as described in the guide step 13.

To summarise: just as stuartgr wrote, currently I get only as far as the repartition step 13 of the guide, and when my phone reboots it does not load into CLK fastboot. All that happens is the white screen with green HTC logo comes up and doesn't go any further. At this point my phone is not detectable via USB.

I have done this process twice already and am sure that I have not missed any step in the guide. I also tried installing cLK 1.5 from SD card (2nd Way) as explained in this thread:

but got same result, my phone still does not boot to cLK and stops at the same HTC logo screen.

I would very much appreciate any help to resolve this issue. In case that unluckily it turns out that my phone is reaching its EOL I was thinking to try NativeSD method – what are my chances? Could you please point me out on good detailed NativeSD JellyBean guide? Thanks.
