Hello, I am a Treo 650 guy and have made a lot of progress in hacking various aspects of the phone, including custom roms, dun, and several others. However most all of these hacks have been accomplished without the bootloader. I have found the bootloader on the phone is known as the Sausalito Bootloader and is a spin-off of HTC's many. It appears to offer a similar list of commands:
Bootload Start
pmsys =0xA171A808
HTC Sausalito Bootloader Version : BOOTLOAD V0.24

However I have found the r2sd and other commands do not work with the palm OS on the phone. They can read the bootloader, but not the operating system. When I flash a custom rom to the phone via the palm programs we use, it is sent as a zip file with a matching md5 checksum. I am looking for a method to restore dead phones via the bootloader as it appears to always remain working to date. However I believe the only method is going to be the same as the Wallaby bootloader patch hack. Using a SD card to write a small program that will act as a reader/writer/and eraser of flash memory.
Can anyone please point me in the right direction? I'm pretty experienced with development, but I've never tried much cross-platform stuff before. Thanks,

Hi, Im having trouble unlocking my CID.
According to awizard it should be ok but Terraterm tells me otherwise. Im using terraterm to backup my firmware directly to my miniSD card but it wont let me. According to another forum, it means CID was not unlocked. Please help?

yup i can vouch on it
I've tried searching, but I can't find anything of use. Could someone please tell me how to remedy this?
In the end I had to uninstall ActiveSync and reinstall it. I also had to hard-reset my TyTn, but everything worked out in the end after about four hours of mayhem.
It sounds like ActiveSync went on holiday. I think there was a post somewhere regarding this that was along the tune of unplugging the phone from the USB, switch ports and/or computers, rebooting the computer (and while you do this, take the battery out of the phone), login back into the computer, put the battery back into the phone, restart ActiveSync. Also, make sure the power is stable. I'd use a laptop so in case the power goes up, the computer would stay on (and a lot of people had issues with Vista (*snicker*)). Something along these lines but I would try to get more verification of that.
Were you trying to upgrade the RADIO or just the OS ROM?
Personally, I'd recommend using mtty to install the OS.
If it is the latter, I'd follow the wiki and do the mtty route (faster and virtually no choice to brick your phone).

hi i have exact the sameproblem, how have u fix it?

i try evrithing but i cant flasha new rom
O2 XDA trion Super-CID
ROM: Original O2 Rom -> XDALive 0.10 -> XALive German (now with error 262)

RUU error codes
For what it's worth ... the following is from a README.doc in a Dopod ROM:
-> ERROR [202, 204] : CONNECTION
This error message will appear when the device is not connected to ActiveSync correctly. Make sure you properly connect the device to the PC through ActiveSync before running RUU.
-> ERROR [206] : MEMORY ALLOCATION
-> ERROR [280] : UPDATE ERROR
When you see any of these error messages, close other running programs on the computer and run RUU again.
-> ERROR [208] : FILE OPEN
-> ERROR [210] : FILE READ
These error messages indicate that RUU lacks certain important files and cannot continue with the update. Please get the complete RUU package again.
-> ERROR [212] : FILE CREATE
-> ERROR [214] : FILE WRITE
-> ERROR [222, 224] : DEVICE NOT RESPONDING
These error messages will appear when remote access control has failed. Check the ActiveSync connection and try running RUU again.
-> ERROR [220] : MAIN BATTERY POWER
This error message will appear when the device’s battery power is not sufficient. Although RUU will instruct you to plug in the AC adapter, it still has to make sure that your device has enough power to upgrade the radio. (Even when you plug in the AC adapter, the device is unable to charge the battery when it is upgrading the radio).
-> ERROR [238] : FILE READ
This error message may appear when, for some unknown reason, the ROM image on the phone is corrupt. Download the whole RUU and try again.
-> ERROR [240] : FILE OPEN
When this error message appears, check whether the downloaded image is placed in the directory of RUU. If, for some unknown reason, you find that the ROM image is not located in the RUU folder, you have to download the RUU and retry again.
-> ERROR [242] : INVALID LANGUAGE
-> ERROR [244] : INVALID MODEL ID
-> ERROR [294] : INVALID VENDER ID
-> ERROR [296] : UPGRADE ONLY
One of these error messages will appear when you use the wrong RUU to do the upgrade. RUU will check if the Model ID and Language ID are compatible with the device. Make sure you use the appropriate RUU tool to upgrade.
-> ERROR [246] : DEVICE NOT RESPONDING
This error message indicates that RUU cannot start the update process. Please contact your service provider for assistance.
-> ERROR [248~260] : UPDATE ERROR
This error occurs when there is an “open port error” before upgrading the CE ROM image.
Solution: You can reset the device and run RUU again. If you still encounter an “OPEN PORT ERROR” again, reset your computer and try again.
-> ERROR [262] : UPDATE ERROR
This error occurs during the CE ROM code upgrade process.
Solution: If this happens, you can just soft-reset the device and run RUU again. The update process will then continue.
Note: At this stage, the Wince is destroyed; instead, it is in upgrade mode.
-> ERROR [264, 274] : CONNECTION
-> ERROR [302~318] : UPDATE ERROR
-> ERROR [320~328] : INVALID COMMAND
These errors seldom occur. However, if one of these errors occur, it could not be recovered and the device had to be sent back to the customer service center. In this case, you have to flash a new ROM code.
-> ERROR [300] : INVALID UPDATE TOOL
This error message will appear when you use the incorrect RUU version to upgrade.
-> ERROR [330] : ROM IMAGE ERROR
This error message will appear when you use the incorrect RUU to upgrade and the image file size is larger than the Flash ROM size. In this case, download the correct RUU version to upgrade.
thx but
-> ERROR [262] : UPDATE ERROR
This error occurs during the CE ROM code upgrade process.
Solution: If this happens, you can just soft-reset the device and run RUU again. The update process will then continue.
Note: At this stage, the Wince is destroyed; instead, it is in upgrade mode.

Try uninstalling and reinstalling ActiveSync. Fixed mine a treat.
Hi,
I get the same issue - no connection through activesync at all. I have tried 4.2, 4.5 and I have even tried to get a connection using mtty but it doesnt offer usb as a connection.
I have even tried putting the update file (using the proper procedure) on an SD card and booting up the device.
I simply cant get XDA live 0.10 to connect with USB to my PC. Tried reboots, reinstalls, soft and hard resets... everything.
Is this a matter of repeating the uninstall/reinstall of activesync or is it better to keep soft resetting the device???
I am lost.
Tar
Sorted it....
Uninstalled Activesync, rebooted and took the battery out of the device for 15 mins.
Then reconnected the battery. Then (without any Activesync installed) I plugged the device into my pc via USB. It picked up the device and installed some drivers in the background.
To check to see if I had a connection I ran mtty which gave me the ////usb connection as an option - thus confirming the device was being recognised.
I then reinstalled Activesync 4.5 and rebooted the PC to find that I could now connect with the hermes.
THANK GOD !!! I have more grey hair however...
I am trying to update my Hermes' rom but i am getting this error no matter what computer I use, what activesync, vista, XP doesnt help.
Is it necessary that I hard reset the device?
Please help me get through this ERROR 262! I've been reading alot of posts and no luck!!
THANKS!!

A little more information about what exactly you are trying to do to upgrade your ROM goes a long way. Which ROM are you trying to install? How? To which device? etc...

No, it is not necessary (EDIT: But the upgrading will "hard reset" your device. Everything will be lost)

Error 262 usually means that the connection between the update program and the device has been lost. I've seen this happening when for some reason the installation of the device drivers after the SSPL loads takes too long. Try rebooting the computer, make sure that no other programs are running, ensure that you get a good activesync connection (green) and then try again. See if it works.
Your computer has Windows XP right?

A quick search suggests that if the pc is fine then the device is bricked (possibly a 2c brick).
I couldn't update the device to LVSW or even SPL V6 with the USB connection Alone.
I've resolved this problem by running the exe from SSPL-HERM.zip downloaded from this forum which put me into bootloader. Then I connect to USB and updated the device with LVSW Successfully! I am not entirely sure why but I'm relieved. Thanks all!

Glad you solved it... I still believe that you had a problem with USB drivers timing out in the switchover from activesync to the RUU. Enjoy the new ROM!!!
I have the same problem

Can someone tell me how i can <<install>> radio and protocol varsion?
Is there any other way than RUUWrapper to flash it?(Whit this tool it always stay on 0% and fails)I have also try HTC Hermes SIM & CID Unlock - v3a whit no luck....

Reinstalling Activesync seems to have done it for me. Didn't change USB port. I also uninstalled a bunch of Apple products (iTunes, iPod reset, Bonjour, Apple Update Utility) without restarting the PC.
Fixed it:

I might be stating the obvious but for newbies like me here if you do not follow the process and do not start by installing and running RaphaelHardSPL-Unsigned_190_1_3.exe first you will also get error [262]. It might be obvious to most of everybody around here but I can see how somebody new might get confused and skip this important first step! Good luck to all!

Thank you for your answer. Now i started mtty.exe as Admin (I have Windows 7) and i have done all the steps you said. But there is no USB in the port box. I can only select COM1 or COM2 but then mtty gives me an error. Any Solution?
Thanks
Did you use the driver that I mentioned in my last post? The situation that you described happens when you don't use the driver.
(If you are using windows 7, you need to install this driver instead of original HTC Sync driver. But it should be a little problem. Maybe the most easiest way is to find some PC with Win XP, there should be no problem ..)

Thank you i tried it on Windows XP and i could connect to my htc hd2 but mtty.exe cant remove the bad blocks and the phone wont boot.
Then i saw another command (TASK 8) in a forum and hoped that this would help but now i have a white screen !! No HTC LOGO... pls help...
Not really sure, but the white screen (without HTC logo) should be normal after this task .. but now you are able to go to bootloader (VolDown), right? So just try flashing official winmo directly from SD card via bootloader (<4GB).
Just for information what was an ouput of the "info 8" command (h.)?

Maybe somebody else will take a look on this problem.

I really tried now all commands with mtty i think the nand memory is totally damaged. But anyway i really really ThAnK yOU for your support !! Thank you cubexe )
Worked
Saved my butt.
I had to get my HD2 to service and restore it to stock after flashing Android.
Problem was that by flashing every version of WM I never got past the startup orange screen (it kept rebooting).
Now it installed fine after checking and fixing memory errors.
I'm curious if it fixes the other problem too but not gonna keep my fingers crossed, seems to be a temperature problem.
Can't install driver
How do you install the driver?
I get the error message: "the inf file does not support this method of installation" when using the "right click > install" method.
I also tried to update the HTC sync driver in device manager and pointing it to the driver files but that didn't work.
hmm.. I have only windows 7.. any other alternative way to check would be great.
Thanks in advance.

Hello, I have a problem connecting devices through OTG to P10 lite. When connecting the gamepad the LEDs light but no reaction on the phone, similarly with the card reader, the LED flashes for a few seconds and no response. I tested on other devices and everything works fine. If someone has a similar problem, please help. Thank you and best regards

The only way I can get it to work is via NEUTRON player which by passes the OS, which is useless when trying to stream music. I suspect it the EMUI os that is getting in the way.
Hi,
trying to get a "GGMM A1" (www . ggmm . com/a1-headphone-amplifier-p00025p1.html) DAC with integrated USB OTG to work.
"OTG Troubleshooter" app isn't recognising a device when plugging it in.
"USB Device Info" app recognises "/dev/bus/usb/001/005" on the "API" tab with the following details:

I get the adapter to work by using HiBy Music Player, but of course this is not the way it's meant to be...
Any ideas who to get this to work?
Phone is rooted, if you need details which require extended privileges to be gathered.
Edit: I already tried a firmware update.
Based on hints in the firmware, a Nuvoton NUC505 is used: caxapa . ru/thumbs/617532/PB_NUC505_Series_EN_Rev1.02.pdf
Because the DAC should be supportet by P10 (non lite), I dont think it is a general problem with EMUI.
my otg is working fine...Im using a samsung adapter and my controller is working
