Try checking the treo wiki and read through everything before trying to perform the rom upgrade. Remember that a simple mistake can and might render your device useless.

"Insert the reader w/card into your USB, after the PC recognizes the card right click on the drive letter. Select Format from the options and make sure FAT32 is selected as the file system then select start.
Also, you need to copy the files to the memory card one at a time; DIAG file first and then delete the DIAG prior to loading the IMG file second.
Step 1:
-Copy the ‘CheeDIAG.nbh’ file to the root directory of a miniSD card. Note: Windows Mobile recognizes updates only from FAT32 formatted cards.
-Insert the card into the device.
-Press and hold both the PTTApp Button (lowest button on left side of device) + Pin Reset (next to miniSD card slot). You will be prompted to press the ‘End’ (red power) key to start the update. This step takes only a few seconds to complete. Once the flash is done, you will see: ‘Model ID: Palm Treo 750’ displayed by the device.
Step 2:
-Copy the ‘CHEEIMG.nbh’ file to the root directory of a miniSD card. Note: Windows Mobile recognizes updates only from FAT32 formatted cards.
-Insert the card into the device.
-Press and hold both the PTTApp Button (lowest button on left side of device) + Pin Reset (next to miniSD card slot). You will be prompted to press the ‘End’ (red power) key to start the update. This step takes about 5 minutes to complete.
-Hard reset the device once the device indicates the upgrade has been completed. To hard-reset, hold the ‘End’ (red power) key while pressing the pin reset button. Answer “yes” to “Erase all data” prompt.
Step 3:
Verify the device software via the device <start><settings><system tab><about><phone tab> The device should display firmware version on the resulting screen."
Good luck!

excuse me for asking,but there`s no file called ‘CheeDIAG.nbh’ or `CHEEIMG.nbh’ in files that are in the /Cheetah/Dumped_ROMs/ folder!
750v:34 MB consists of 3 .RAW files(What to do with them?)
treo750vrompartial_bcaslis with .RAW files inside,also
Treo750v_Dump_Cingular_ROM.zip with .dll`s mostly
Did I understand something wrong....?
Any help
THX in advance!

Roms
There are NO installable roms on the FTP!
The usable one is in the possesion of forum members.
Palm and/or Cingular asked politely ;-)) to remove them.
So you have to wait untill the new rom will be released later this month

i didn`t have time till now to wiew all the posts about this phone,and only now I saw that still there aren`t ROMS available.
If anyone has a ROM or a link for it,pls PM me!
THX in advance!

Sony xperia L dead (no boot,No notification light,no charging,No fastboot/flashboot)

Hello guys!
- I've unlocked the bootloader
- I've flashed CM12.1-20151010-NIGHTLY-taoshan and it was working very well
- I flashed (xperia apps, Gapps)
Then i expand my phone memory by aparted app.
Until now everything is going well- I did everything step-by-step (Busybox, link2sd, partition for SD card .etc)
Then after some days, my phone started crashing and recovering automatically.

my phone was working
But i reboot the phone to apply the changes!
And that was the last time I see the screen on!!!!
My Sony xperia L now (Doesn't boot, No notification light, doesn't charge, No fastboot, No flashboot, Not recognized by computer app Pc ompanion or fastboot or flashtool ....) Simply it's DEAD
But when i plug it to my laptop I hear that sound when you plug any USB device...
The first time I plugged it after it died .... I noticed the laptop is downloading some driver "Qualcom ..." or something like that name
Is that the CPU driver!? and why it only detect the CPU!?
- I noticed when i plug it to my laptop if it didn't recognized the phone, i press on power button so it makes that sound when i attach any other usb device.... after few minutes it makes that sound when I removed the usb device but i can press again on the power button and it recognize it again

Eonon GA5151 beeps but no display?

Hey there.
A while back I set the power off on this unit (flashed with a Malaysk ROM) to go off after 5 min. It seemed to make things buggy and often had to be reset after I restarted the car.
One day, it just didn't come back on. No lights on the buttons. Holding down power and reset doesn't seem to do anything.
When the ACC is powered on, I hear two beeps coming from the CANBUS.
Anyone else encounter this? Better yet, does anyone know of a solution? Not sure I can accept that it's burned our or bricke yet. .

Mine is currently screwed.... I bought an Eonon GA6164F MTCD_KLD and the steering wheel controls were buggy and a mess.
Their support gave me a link to an update.img file, and it wouldnt work through the normal Settings \ About \ Software Update (couldnt find file) I renamed to dupdate.img and it found it and wanted to install.... rebooted, did its thing.... then black screen...
I cant get it to do anything now..... ive even removed battery, tried all the resetting combo's with the reset + power , let go of reset, let go of power... cant get anything on the screen..... worst still, ive only had this thing for 3 days... WTF... I tried using the recover from brick with a bootable SD card in the GPS slot, but cant get anything on the screen at all.... perhaps its a bad update.img file, but surely i would see somthing on the screen....

And from today I have the same issue.
Ga6161f. Support advise me to rename update.img to dupdate.img.
Now I have just a black screen, no any sign that is powered, and light just came when/while I press reset button.
I escalate it to vendor and probably it will be returned to them.
Does anyone have some advice how to correct it?
Is it dead, HW damaged or just black screen?
Thanks to all ...

I did get a tiny bit further last night, i loaded up the latest Malaysk 11.4 firmware onto an SD card and made it bootable using SD_Firmware_Tool.exe.
Unplugging the rear plug of the stereo (to make sure its powered down)
Put the SD card in the GPS slot
Plug the rear plug/cables back in
Turn ACC on
It at least showed somthing on the screen then
I noticed it was Restore 5.2 where before i was Restore/Recovery 5.1.1
It failed to install the firmware
I tried using the menus and tried all other methods of getting either the Malaysk or the Feb 2017 Eonon provided firmware through the usb or normal SD slot, but it would only error and then a Reboot would still leave it doing nothing.

I managed to fix my device.
Long story, but ive started writing up a document.
If I can get to 10 posts, I can start a new topic and include spefics. including pictures. but for now.
This is my rough text.
It might be able to help you too.
BTW. once I had the Malaysk version working, I attempted to re-install the update Eonon had given me and it bricked the device again.
So its def. something bad / funny with that file they supplied.

That's great news.
You can change the boot logo in the settings- factory settings - logo. Don't fiddle with other settings in there unless you have pictures of what they are when it's all fine. I'm glad I could share the knowledge and you got yours working too. It's not documented very well , I spent 24 hours digging through forums to finally get that procedure ... oh well

You did a GREAT JOB !
Now there is a manual.

Thanks

Hi I have a Eonon I think it is a GA6201F it was installed in the care before I got the BMW so I don't really know Its not that old ,My problem is It was working when I fires got the car then it stopped I contacted Eonon.com and they sent me an upgrade I had the unit pulled out at the time of upgrade then after I installed it back in it wouldn't work I checked the power supply that's ok I checked fusses they are ok then I tried to reset it no beeps and no lights black screen holding the reset button in as well as the power still no beeps and then when I let the reset button out the lights are on but they are red and then when I let the power button go they go out then if I push the reset button and then release it the red tight comes on for one second and then it goes out ,can it be fixed the person I got the car off payed nearly $500 for it I cant afford to get another one I will need to get a cheep cd player that may not fit properly or leave a big hole in my dash or do I walk across the road to the water and see how long it takes to sink after I throw it and let the fish fix it because they might have more luck than I have

Haven't been around for a while and thought I'd try to fix the Eonon GA5151 I have. Did a Google search and ended up back on my own post.
I tried to follow your instructions but did not have any luck.
The screen does not turn on. Here's what I did:
1. Used Rockchip program to create update SD card using update.img provided in the RK3066 Malaysk ROM (can't check SD boot anyway as the program crashes if I do).2
2. Disconnected plug at back of Eonon unit; inserted SD card.
3. Re-inserted plug and waited
4. Nothing ...
I still get the two beeps coming from the CANBUS but I'm not seeing anything on the screen. Now I'm beginning to wonder if I should check my remote wire or something else. It just makes no sense to me how or why this is going on.
Any ideas?

[Guide][UnBrick] How to unbrick the Acer Liquid Z500

Hello, y'all,
... First of all, please read this whole post carefully, before starting to work on your phone! Thanks! ...
recently, I wanted to update the Android version of my old Z500 with the help of lineageOS and TWRP.
Please note, that I'm not at all an expert on this topic, and if I'm using specific terms like "bricked" or "APX mode" wrong, please forgive me.
So, on my device, I had the plan of installing Android 6.0 on this phone using TWRP and a copy of lineageOS.
However, the recovery partition turned out locked and I accidentally overwrote the boot partition with the twrp.img.
This is my first time doing this, ok, and I read on a oneplus forum, that the boot partition could also be used, blah, blah, blah, silly me.
Anyways, now my device wouldn't turn on. After a while charging, the display turned on, but there was always just the low battery screen. When I got to the "Boot Selector" holding the power and vol + button, selecting fastboot, recovery or normal boot just restarted the device.
Anyways, now what do you need to "unbrick" the device :
- A version of TWRP [dl.twrp.me/Z500/twrp-3.3.1-0-Z500.img.html]
- A version of your desired ROM, for me lineageOS [androidfilehost.com/?fid=889764386195903470]
- SmartPhone Flash Tool, for me v5.1912 worked like a charm [spflashtool.com/download/SP_Flash_Tool_v5.1912_Win.zip]
- A copy of the Firmware Acer_AV0K0_Z500_1.012.00_EMEA_GEN1 (... GEN1s for single SIM) [dl.dropboxusercontent.com/s/cin08ytkqmvr7c1/Acer_AV0K0_Z500_1.012.00_EMEA_GEN1.zip] (this was the hardest one to get because all the other downloads just included the .ispff dump file)
- A copy of the corresponding version of OpenGApps [opengapps.com]
- A copy of the MediaTek Driver Auto Installer (v5.1632.00; you know you have the right one when it resets the USB Ports in a CMD window at the end; INSTALL THIS FIRST) [mediafire.com/file/4ux1ytmzlxmpbjb/ROMProvider.COM_Driver_Auto_Installer_EXE_v5.1632.00.zip/file]
- A USB Charging Cable
- A PC
- Your Phone, obviously
Set up your PC :
1. Start by installing the MediaTek Driver Auto Installer. After that is finished, restart your PC.
2. Unzip the Firmware and the SmartPhone Flash Tool
3. Copy your ROM and OpenGApps on an SD Card.
Before you begin this operation, make sure you "get your device into APX mode".
Basically, it makes your device recognizable and flashable by the computer.
WARNING: DO THIS AT YOUR OWN RISK.
To do that follow these steps one after another :
- Plug your device into your wall power, NOT YOUR PC, and let it charge for about 30min, just in case. Turn it off if it's still on, although in my case, it turned off once I removed the charging cable.
- Remove the backplate of your device, unscrew the internal backplates 6 screws and carefully take the internal backplate off. If you're having trouble, just look for "Acer Z500 teardown" on YouTube.
- Carefully pull off the battery connector from the mainboard from up under. Be careful not to damage it!
- Once done, connect your device to your computer. You should now see the device as COM Connector in the Device Manager. If your device is disconnecting and connecting repeatedly, the driver must not be active. If you see no device connecting at all, remove it from your computer and after plugging it into the wall charger again, reconnect it to your PC.
- Once that's ok, disconnect the device again, and plug the battery back in.
- While disconnected, open up the SP Flash Tool, and under "Download", select the scatter .... .txt file from the Firmware Archive.
- Once that's done, all of the checkboxes in the ROM select should be active.
- Double Click on the Path of the "RECOVERY" row and select the TWRP.img. Then, change the mode from "Download only" to "Format All + Download" and hit the "Download" button.
- Plug your Z500 back in again, and you should see the flashing process starting.
- Once that's done, disconnect the phone and put the SD card with your ROM and OpenGApps in.
- Connect your phone to the wall charger again, and immediately hold the power and the vol + buttons down, till the Boot Options appear.
- Boot into recovery mode, and TWRP should start up. If it doesn't, reconnect your phone again and just let it boot for around 3min after terminating it by holding the power button and as soon as the screen goes black, also holding the vol + button. Once again select recovery mode, and now TWRP should defiantly show up.
- In TWRP, first, make a factory reset with the "WIPE" option. Then go to install and choose your SD card. First, install your ROM, then OpenGApps and reboot.
Now you should have a functioning Acer Z500 again!
Feel free to reply, if you have any questions!
Good luck,
