Why didn't you try to force the device to bootloader and try again? DON"T PANIC!!!
Then Use the RUU tool attached! and put your favorite xxx.nbh in the folder

1. restart computer, or
2. reset your Hermes, or
3. uninstall Active-sync, then install again (may need to restart PC again),
OK? ^_^
P.S. be sure that you had tick the usb connection option from the activeSync option. ^_^

Alpine Blackbird 2 - Unlocking The Undone

Hello!
I've been out of the phone game for a while (plan on coming back soon though), but I've been tinkering around with random things.
A few months back I picked up a new car that had a double din alpine head unit, and behind the head unit this PMD - 200 Blackbird 2 was being stowed.
Interested in what it was, I quickly learned it was a Windows CE 4.2 based device that alpine had applied a skin to.
As I started messing with it, I realized that whenever I turned it on, it would just go to a black screen. After looking around online and talking to some Representative at Alpine, there was no longer any support for it and they pretty much told me to go screw myself with my obsolete device.
That's fine, I said...I'll figure out a way to get it working. Obviously the device is home to a Win CE infrastructure and I'd be happy with having that alone...and from there I could do many things.
So I started messing with it. Pushing different button combinations seeing if it would boot into a boot-loader or anything. To my avail, about 15 minutes in I had it booting into Windows CE. I Simply held the reset button and the power button for 15 seconds, let off the rest button, it powered on, started playing with the center button...and poof...Windows CE appeared.
So I start messing around. Checking out the pre-installed data and such. Im about to wife all of Alpine's crappy software and have it boot strictly into windows, and by accident I clicked an icon that booted me back into Alpine's overlay.
No matter! I'll just boot back into windows! So I hold the reset button and turn off the device. Then I go through the process of booting windows again....and nothing...it boots straight into "Map Update Mode". I keep trying the same thing, but the more I try, the more frustrated I get that it won't do what I had it doing before.
That's okay. Map update mode is essentially saying the device is looking for update. Oh..I'll give it an "update" alright I said...But it's plainly recognized as a mass storage device.
MY problem is, this has become about alot more than what Im going to do once I get back into windows. It has been bugging the hell out of me, and I REALLY need to get back in, but Im just running dry. There is absolutely NO information out there about this(well, for the blackbird 2 I should say)
I'll list everything I've found so far, if anyone at all has some words of wisdom, a suggestion, or even knows how to do it...please help me out before my head explodes..

USB Connectivity only appears to be viable when the device is in "Basic Boot". At that point it appears a s a mass storage device.
ANY HELP would be GREATLY appreciated. You can tell how much this is bugging me based on how in-depth I made this thread.
As stated before there is NO information on how to do this, so this is practically a developing thread. ANY comments to further this are appreciated!
Thank you!

i too got to play with windows ce and all the fun apps that alpine stacked on my unit. all of which worked until a faithful reboot and now i can get any screen action unless i use the vol dwn pwr button method. i'm stuck. i use this in my truck quite often (mostly for the mp3 player and bluetooth functions) but i'm pissed i potentially bricked this piece. if only i had made a BACKUP! anyway. let's see if we can crack this case and get on with the fun stuff! (like miopocket 4.0)
edit: also when trying to apply the patch for the pmd b200p (which worked the first time) it now hangs at 26%... no idea...

Nothing like reviving an old thread, right? I just bought one of these on ebay and it's on the way right now. I think I found instructions on another site to get to the Windows CE environment for this device but can't confirm it without the device itself. I have an IVA-W505 and want to either force updated navteq maps to the device or better yet, replace the GPS application entirely. I hear the one alpine puts on there is rather buggy so I've been trying to find alternative options for GPS but want to make sure I can get some up-to-date maps. Also wanted to look into some cool applications and interfaces and see if maybe I can figure out how exactly it starts working when docked inside the alpine head unit. Too much to learn and sadly, not much experience trying to figure out how exactly a device works.
I've been collecting links for reference once I get the device, if anyone wants them let me know and I'll try to find them all and post them. I work from 8:00 AM - 4:30 PM EDT/GMT -4 so I can probably respond pretty quickly within that time frame but may respond a little slower outside that time frame.
If anyone has any suggestions for things I can do or requests for information I should try to collect please let me know, I am hoping to have the device by the end of next week
---------- Post added at 10:56 AM ---------- Previous post was at 10:51 AM ----------
I found the instructions to access Windows CE (unconfirmed till I get my device to test) and put them below with the link I found them at:
to unlock the PMD-B200P (the "second" version with Alpine's own version of IGO), you need to reset it, hold the up arrow when powering on. then when the update screen appears, reset it again and this time you need to hold the music button when powering up.normaly this works. if it doesn't (sometimes it doesn't, I don't know why), restart the whole procedure).
then you get a screen where you can choose to launch the satnav, WinCE, update, ... at the right bottom, there is a button "enable/disable menu" . if you set it to enable menu, everytime the unit is powered on you will come to this screen.
I am running this unit now with IGO8 and it works great.
- just empty the "flashdrive". if it's not visible, go to "control panel", "storage manager", select "IDE hard disk", on the right panel, select "properties" and then select "mount". and close all windows.
- copy the IGO map to the flashdrive and rename it "Alpine"
- in the Alpine folder, rename the IGO.exe to AlpineNavi.exe and you are ready to go :dance:

If someone is able to test this, let me know if it works?

So after many attempts and further research I don't seem to be having much luck with accessing the Windows CE desktop on this device. I'm going to keep trying of course. Any suggestions for getting further toward getting any kind of unlock would be greatly appreciated

i used the update for the uk model to give me a boot option to load to windows ce instead of the nav software. i'm currently running navon (igo 8.3.5) for gps and it's working great! i'm currently trying to get bluetooth to work as it used to. sorry for such a vague post but if any of you are still tinkering with the blackbird please contact me! would love to share notes!

Alpine PMD-200B attached to Alpine IVA-D106R
Hi to the list
Hope posting in the right section.
I ownn an Alpine PMD-B200P iattached to an Alpine IVA-D106R and i would like
to update it either software and maps.
I have tried changing the IGO8o software with an early release but since i use the PMD
without the autoradio source ( as portable ), everything works great but as i attach it
to the source, the Navigator keeps working OK but i get no audio from the car
speakers, not even the Tick on the display.
Anybody can help me to solve the problem or it is possible to unlock it but does
still work also attached to the Autoradio?
Any help will be really appreciated.
Thanks in advance
Enzo.

Hello,
i cannot get it go.
What i have done is:
Downloaded from the Alpine site the file called FU_PMD-B200P_20_20091008.zip.
Unzipped it and got a folder called FU_PMD-B200P_20_20091008.
Opened the folder and got 3 folders and 3 files.
Copied them in the root of a 512MB SDCARD.
Inserted the SD CARD in the PMD.
Pressed the Reset Button.
While pressing the Music button ( the one on the right side ) i've pressed the power on button and keeped pressed both.,
but i do not get into the WINCE.
I have noticed that keeping pressed both the buttons, i can see on the display the word
Loading...
and after about 25 seconds i get the Alpine Logo and then the navigation program loading till the end.
Nothing happens.
Please am i missing any step?
Any help?
Thanks
Enzo.

Enzo, I have a 1 version of this thing, had it for several years and it still works attached to my radio in the car.
I am also willing to give away the audio for a better navigation, but today is the first time I ever find out anything about this device.
Where did you get Igo8, did you use the procedure described in the first 3d?
I have actually 2 blackbirds 1, 1 works in the car, the other one is stuck on update because I had a cd with no code, and was thinking on cracking the one that is "blocked" and keep 2 units in the car.
This is really interesting!!!

Good day,
I have got TCL Android TV model No. L55C8US with software version: V8-R851T02-LF1V252.011680
I want to downgrade software version to: V8-R851T02-LF1V187.008562

1- Is it possible?
2- Where can I get this version (V8-R851T02-LF1V187.008562)?
3- how can install the version into the TV?
Your feedback is highly appreciated.

Yes. It's possible.

Would you tell me how do I proceed with installing the software to the TV?
I downloaded the software file that has provided by you and I copied to USB flash drive after format FAT-32.
when I'm trying update local mode it shows error box, it says that No avaliable update file please insert USB device with software package.
I'm very sure that the USB is healthy and it's recognized by the TV.
Please help.

If it's in update.img format:
Hold power button on remote and choose power off. Or power off normally and und unplug the TV from from power.
Next with flash drive plugged to usb power on TV by press and hold the physical button on TV (not remote) until the led light on TV starts to flash. And wait.
It can question about older firmware so you have to agree.

TCL 65P815 firmware update problem and few things

Hi,
My problem is with 65P815. Fabric software was v084, i tried to update to V191 official version from TCL page, but after update and turning off TV, there is nothing shows on screen. I hear only sounds, and remote clicks, menu gone etc.
I search for info, and go back to v083 software, that helped and fixed TV. But now I don't know what to do to fix my TV. Tried to update with factory reset, nothing helped. Any tips how to deal with it ?
Next thing is concerned with soundbar thing, I have LG soundbar, is it possible to control soundbar over TCL's remote ? On my old Samsung TV it worked normally.
Here in TCL I don't see option to choose sound sourec (tv speaker/optical/hdmi), there is no option to mute TV speaker and move sound to soundbar. For now I use 2 remotes, but I want to use only one like in Samsung. I connected soundbar with optical cable to my TV.

Hi there. Trapped into same thing. After flash, I can hear 'bing' when you navigating in menu, backlight is working, but screen still black. Tried to flash V191(Inserted stick to USB2.0 with Update.img and plugged in with power button pressed). But got same thing. Led is blinking during i suppose flashing, but after that - nothing. Can it be somehow reset to stock or whatever?

you have to go back to 0.83
Turn off the TV, plug out the cable. put the drive into usb 2.0, press power button on TV's back and plug in power cord, if led start blinking wait about 10 mins to finish flashing. Sometimes you have to do this twice and TV will be ok.
Write to TCL support about your problem, let them prepare patch

Hmm... I have couple of questions then.
Does that mean v083 firmware didn't published somewhere?
And does that mean that we can't update 65p815 to any new firmware with Android 11?

what was your native FW ?
I tried to update to V191 which is on android 9, and update was failure. There is something wrong with the FW
File upload and sharing. Large file transfers. Free online cloud storage.
Visit this link to download: V8-R51MT02-LF1V083.zip
files.fm
here you can find v0.83
Android 11 is in beta now, we have to wait for official final update

I didn't check my original fware version. I know that was very stupid, but i supposed that just platform is matter.
Thanks for link. Will try this fware. Hope that will help, because i don't like to waste time with support, that usually just redirects to another operator...

it should, try second time if the first will failure

Ok, i just finish downloading and i'll start bring that baby to life. Thanks for help. Will report if suceed.

report it to TCL support to make technical request, and to fix that firmware

Ok. Just flashed twice. God damn, you have been right! All works like charm!
If someone will be as "lucky" as me, steps are next:
1. Load to local pc zip from above.
2. Format flash stick with FAT32 and copy it to root.
3. Insertt stick into USB 2.0 port.
4. Turn off TV power physycally.
5. Press and hold On/Off button on a TV's back and plug TV holding button pressed.
6. Hold for 10 secs, the led in front of TV will start blinking - it is ok.
7. Wait till it will stop blinking and wait some 5 mins after that.
8. Repeat steps 4-7. After TV restart it will show TCL logo and Android welcome screen will appear.

Ok now we should think about how to flash properly new version of FW,
latest official firmware is
https://www.mediacenter.tcl.eu/uploads/common/R51M_Android_P_V191.zip
When I try to flash with it, from menu update/local it works but only first time. When I turn off TV, then screen is black
I found such instruction, what to do after installation
Press the Settings button in the remote control:
Press OK on the icon: Picture.
Then go to the line Advanced settings.
Scroll down to the line: Brightness settings.
Scroll down to the line: Contrast.
With the remote control, do the key sequence: 6 4 2 5
The special menu appears.
Go to the line “Reset All” and press OK.
Go to the line “Reset Shop” and press OK.
Now unplug the main power cord.
Wait for ~2 minutes.
Plug back the main power cord and perform complete installation.

Seems on mine 65P815 by your table, the code should be ST6451D02-3 (code 305), but i have ST6451D02-H (code 283).

I have flashed v272 (img file) from v084 to my 65P815. Flashing went smoothly with no black screen ecountered. v272 works nicely with no problem.

@ancifil said:- "Did you reboot your TV after that?"
Sure I had rebooted it after flashing as I have been using this firmware for about a month.
I remembered flashing it 2 times. The first time was not successful (can't remember due to what). The second time reflash (same as what you did as in post #10) was smooth and without any problem.

jngiag, looks like it should, as for me... Maybe, i shall try 272 one more time.
superfly86, did you try 272?

Btw, one thing. Can you remember, after you had flashed 272 first time and after that launched flash menu, to flash second time, was you able to see menu?

I think it was due to a request to input pin while I was trying to setup live TV. I did not know the pin so I powered it off and reflashed as in post #10. Sorry, I can't remember it exactly.

Your 65P815 with panel ST6451D02-H...... Project ID MUST be 283.
This is your problem with firmware (black screen ) !
So you need to change ID number from 305 to 283.
To modify the project ID, when TV is ‘ON’, with the remote control do the key sequence
0 6 2 5 9 8 .....MENU.... 283.
At the end of the key sequence the TV must reboots alone if the project ID has been understood by the TV. If it doesn’t, update the product with the last software available and try again.
Sometimes several tries can be necessary for successful project ID modification.

I've got that. But the hard thing is that i will not see this manipulation... I have to do that blindly. Risky stuff, right?

Soft locked my Android TV?

So...
I was dumb enough to play with the developer options hoping to find an option to deactivate adaptive screen resolution. instead i clicked on something and now my tv is kinda soft locked. at first it was stuck in a boot loop, eventually went into recovery mode here and there (see attachment, maybe there are some informations that could help solving the problem) , but i couldn't select/press anything bc this tv only has a power button. Later i found out you can use an USB keyboard to select stuff in recovery mode. So i grabbed my keyboard and waited for the RM screen. but it wouldn't show up. idk why but now its booting "normally", even shows the android logo. but then its just black. eventually the TV turns off and then back on, over and over. i tried every button combination I could find on the whole internet. Nothing seemed to work. One combination got me some hope but that hope disappeared quickly: i unplugged the TV, held the powerbutton, plugged the TV back in, still holding the power button, and waited.
after a short time it showed me a monitor looking like symbol with a gear icon on it and the gear was crossed with a red X. under it it was saying "error". (see attachment) ("Fehler" means "error" it's german)
so here i am. idk how i get it back into recovery mode so i can try that keyboard method.
and since i got that TV from my gramps, I don't have much information about it either. just got the TV and the remote from him.
I just know that it's the TCL 43EP640 respectively 43EP640X1. (Theres a sticker on the back of the TV, see attachment) so yea. I've heard you can update the firmware/software using an USB stick but idk how and i couldn't find any firm-/software for this TV
If you've read to this point and have an answer to my problem: I Love you
