[HD2 General] Idiot999:
This is what happens when you think you are smart, and you ain't.

I bought HTC HD2 online from a guy who installed an android OS on it. No warranty whatsoever. He said to me: it freezes sometimes; just remove the battery, get it back after some time, and it will work again. Well, he didn't mentioned that happens a lot. Like, after 10 minutes of stand by. Anyhow, I read some posts on this forums, and I figured out that it has something to do with the OS itself. Hell, I'm a programmer, I can install the correct OS myself. How hard can it be? Well... If you know about computers, you think you know about phones. You don't. The 'battery removal and waiting process' really pissed me off, and after 2 days of getting the phone, I couldn't help but try to fix the thing.

So, I read about how to do it, on this forum. It was a while ago, so I don't really remember which guide it was, since I gave up on the device for months. I think (but not sure), it was the guide from Cotulla (if he created nand for HD2, than i think i followed that guide). So, my PC environment still is win7, as it was back then. I followed the guide, and on the first execution of the .exe, win7 filed an error. My phone was plugged into the computer via usb. I read: do not remove the USB cable, you will brick the device, so I didn't. For I think 5 minutes. Then I unplugged the cable and tried again. Well, it wouldn't start anything. I took 7 days to find a solution to this. I found nothing. I wanted to smash the device with a hammer, but it is I who did this, and the device isn't guilty. So, I shipped the device to Novi Sad (city in Serbia), to have it fixed. From shop to shop... No one could fix it. However, in one of the shops they removed the previous Android. Now, after several months, i want to fix the device.

So, this is the device: HTC HD2 T-Mobile. Made in China.

Last week, I started the device, to see if I can get 'USB' after 'SERIAL' in four colored screen, and I did get it. Today I plugged in the device again, and it started heating, really bad. I did not burned my fingers, but it was pretty hot. After that, I wanted to connect to get the "USB" on the screen, and it started vibrating. I thought this is normal, and it will stop. It didn't. I removed the battery, and now I'm waiting to chill a bit, before telling you exactly how it behaves.

When I start the device normally it says: software update failure; try again. Then it shows the three-four colored screen, and it turns off.

Then I tried holding volume key down, and pressing power button. First it said something about 'rom error', but it switched screen to 'Loading...', and I couldn't see what it said. I waited for it to load, which never happened. I tried to hold power button, but nothing happened. I removed the battery. Took my phone to record what its written, but it want start at all. I took the battery out, and waited for a couple of minutes. This time it didn't go to 'Loading...' screen, and I could see what is written: Upgrade ROM code error. Please try again. In the bottom of the screen it says 'Serial'. When I plug in the cable, it turns from 'Serial' to 'USB'. I figure it's not bricked, but I am an idiot, so, I could be very wrong.

The boot screen looks like:

Top right corner: RUUNBH

PB81120 SS-B3

SPL-2.08.HSPL 8G XE

0x05

CotullaHSPL 0x50

Serial (after I plug in the cable), it says 'USB'.

So, I tried to flash HSPL4 for Leo, again. I get the error: CRITICAL ERROR Flow:00000002

Error code: 00000003

Description: USB OPERATION FAILED

Then again, but flow is 1, and error code is 2.

People, I wouldn't address you if I wasn't desperate. I tried on my own. I tried with 'professionals'. You are my last resort. I'm sorry for writing such a long post, but I wanted to give you an insight what happened. This is all I know about this device. I don't my money back, its the best phone that I could ever afford to buy... Should I toss the thing, or is there a way to fix it?

Edit: I tried to install MAGLDR 2.0. First time, it took like 20 seconds to fill in the progress bar (100%), and after the device rebooted, the screen turned on, but nothing else happened. There is nothing on the screen. Than, I took it for a check. I ran Rom update utility, to check if there is version of MAGLDR installed. It was empty. Then I clicked Update, and the phone rebooted to MAGLDR. Again, the screen is on, but nothing is written.
