I completed the update, but for some reason when I switch to GSM radio I am not getting "E" icon, only "G" and it appears that there are only GPRS speeds. Is anyone else having this issue? Not sure if it has something to do with the radio that was installed or possibly a network issue in my area...
[Palm Treo 750 ROM Development] alambrito:
I´m also having data speed problems

I´m having the same problem. I have HSDPA in my area, and although I´m getting the H and the 3G icons, I´m only getting GPRS speeds. I´m thinking along the same lines. That it has something to do with the radio installed. Could we flash the radio version alone?

I have hard resetted and reflashed the WM6 ROM with no help. The process completed "sucessfully" and right now the phone works, but data only works at GPRS speeds. I guess we´ll have to wait for Olipro´s new release and see what happens.
[Palm Treo 750 ROM Development] jaadkd36:
Here's what I did. This seemed to work perfectly. I have not been able to check whether my Treo is fully unlocked (do not have a foreign sim available just yet), however I was able to flash a Hermes radio.

The steps:

Turned off security on the device by running the Security Configuration Manager.

(SCM is available from http://www.sems.org/entry.asp?ENTRY_ID=157)

Instructions to install & run the program are available from there, as well as the .cab and program you will need.

After turning off security, I started the Cheetah Unlocker, but copied the two cabs from the C:/TempChee folder to my device, and ran them before I sent the device into Bootloader mode. After this, I followed the instructions to the letter and had no issues.

After all was said and done, I was getting slow data speeds. It was mentioned earlier in the thread that we can use Hermes radio code, so I flashed radio 1.54.07.00. (available from the Hermes upgrading forum here on XDA.) After this, the data speeds were much improved.

The Treo seems to run normally, with a speed increase on dialing and hanging up from calls. I am not sure whether that is just a function of the device having a fresh ROM install or the new radio.

(On a side note, Olipro- your work on the unlocker is much appreciated!)
[Palm Treo 750 ROM Development] manfly9884:
How did you flash this radio. I've tried but my screen goes dark and them I get a Error message that my pc can't communicate with mydevice. I am unlocked so I am a little confused.

Thanks.
[Palm Treo 750 ROM Development] jaadkd36:
In the temp files created by the radio software nstaller, I found the .nbh file, renamed it to CHEEIMG.NBH and flashed that to my treo using the SD card bootloader method (hold down "media" button and hit reset at the same time.) The phone came up with the "CHEEIMG.NBH" standard flashing screen (grey, with progress bar at the bottom). Unlike normal flashes, the only thing listed was "GSM"- obvious, since we're only flashing the radio code.
[Palm Treo 750 ROM Development] pderosa:
OK I was able to fix my issue of not getting "E" and I also noticed that I was not getting "H" when in 3G. It had something to do with the radio. I flashed it to 1.54.07.00 Hermes. Everything is back to nomal and speeds are good. The interesting part was that I had a network outage last night and this started the problem.
[Palm Treo 750 ROM Development] alambrito:
All fixed

Flashed the radio with 1.54.07.00 and my speed is back. Used bootloader method described by jaadkd36. My last tested d/l speed was 810 kbps.

However, my SIM is still locked. Last time I checked it said I had tried 11 times and that I had to wait. Don´t know if I´ll try again, maybe I´ll wait for the new release.

Thanks all for your help.
[Palm Treo 750 ROM Development] Hitec Wireless:
can you explaine how exactly you manage to boot from SD card to flash radio in to Cheeta , i loaded the file as per previos post but it doesnt boot to radio upgrade screen , i renamed NBH file ,loaded to sd and nothing hapening when i try to reboot by pressing media botton and reset .

Hitec
[Palm Treo 750 ROM Development] Olipro:
Just a warning... there is a possibility the SPL for Cheetah doesn't support the rseed command as required by radio BL 0108 and hence... those on 1.54.07.00 might well be stuck with it.
[Palm Treo 750 ROM Development] sucker00:
My Experiences with Hard-SPL:

Yesterday i upgraded my Treo750v wm5 (Treo 750-1.16-VFD) to wm6 (Treo 750-2.18-VFD).

But i wanted to know if i can go back to wm5 with Hard-SPL.

Today i switched back to wm5 with Hard-SPL

Steps:

1. followed these instructions:

Here's what I did after getting error 270 on step 1 :

- While the Cheetah Unlocker is still open, go to C:\TempChe directory and copy the files, Cert_SPCS.cab and EnableRapi.cab, to root directory of a Treo and run both cabs on it.

- Close the Cheetah Unlocker and re-open it again and start Step 1 Flash SPL again following the steps in this thread http://xdaforums.com/showthread.php?t=335661 and it works for me.

2. downloaded the file PalmTreo750vUpdaterDE.exe from May 2007.

extract the .exe file to a folder with winrar - copy the file CHEEIMG_FW.nbh to your fat32 formatted SD-card - rename the file on your sd card to CHEEIMG.nbh and follow these instructions to upgrade to wm5 rom : http://wiki.xda-developers.com/index.php?pagename=HTC_Cheetah_Upgrade

Regards

and many thanks to Olipro

Thanks Olipro for the hard work, works like a charm..

Can't wait to see the many different Treo ROM's! Until today I've found myself a bit out of the ordinary since I've switched from the HTC Prophet to my Treo 750v. Fewer tweaks, and almost no ROM's. Now there is light again at the end of the tunnel :D

[edit]

I was typing this while finished Step 2. After this I've got the Error for .NET as mentioned before in this thread.

Downloaded the latest: CheetahUnlocker.exe But I can't find any .CAB in C:\TempChe

Also installed Cert_SPCS.cab that was already on my PC, I used this also to get rid of the anoying messages when I want to install CAB's on my Treo.

I didn't let me proceed with Step 3, so I'm still stuck there :(

[/edit]

[edit1]

Tried installing Cert_SPCS.cab and Enablerapi.cab I've found on the net. Still the same. Could not get passed step 3.

[/edit1]

[edit2]

Okay, it's been a very long day. :p

Since I own a SIM unlocked Treo I've read that I only had to finish Step 1. Now I've finished Step 1 and 2.

As I understand I don't need to perform Step 2 and 3, since my Treo is SIM unlocked already!

I was wondering, is it okay? Since I've finished Step 2 and didn't proceed with Step 3.

Again, I should go to sleep.. ..so I will check in again tomorow :)

[/edit2]

I think I should just shoot myself :p Wasn't able to start step 3. It shows the message that my device should be unlocked with a program? Checked the temp dir for the 2 CAB files, but there not there.

After I hit OK on the unlock message I get the .NET error.

Will have another look...

Radio Signal

Has anybody had a problem with signal strengh after this? I am having major strengh loss. Before I was getting full bars, now about 3 bars, plus alot of missed calls. Not dissing anybody, just want to know so mabey we can fix this.

Thanks
[Palm Treo 750 ROM Development] pderosa:
I didn't really notice signal strength issues, but I was having a lot of trouble with the data connection. It was working fine for a while and then started to drop the signal and not show the "H" when transmitting in 3g. I flashed a more recent Hermes radio (1.54.07.00) and all problems were fixed. I however was told by Olipro that this may cause issues and I may not be able to change the radio again. For now everything is working great and without issue. This was all with the original unlocker. I'm not sure if the new unlocker has a different radio or if there was something else causing the issues.

[Palm Treo 750 ROM Development] Clarkie:
I have seen from earlier posts that there's a version 1.54... of the radio firmware available (from the Hermes?), and I'm keen to improve the phone performance of my device. I've got 1.52.30.00 at the moment - which is better than the Vodafone one (1.47...) at holding onto a call, but can still be a bit flakey.

I've run the unlocker, which worked ok (somehow my MiniSD card got corrupted, cos I didn't take it out of the slot), and then ran the 'Unlock Radio' step. This caused my Treo screen to go black and disconnected the device from the PC. I tried it a number of times, and always the same. I have never reached 'step 3' in the application, to update the radio.

In the end I decided to re-format the MiniSD card, put the CHEEIMG.nbh file onto it and re-boot back to the H3 ROM, as it was before.

I want to try again, so is there something I'm not doing in the process? Also, Olipro said that the 1.54... version may cause other issues - should I just stay away from it and put up with my current versions anomalies?

Thanks in advance. I am in awe of the time you all spend helping each other out, and the extent of the knowledge that is clearly shown by people like Olipro. Much respect.
[Palm Treo 750 ROM Development] Olipro:
well, it won't cause any "issues" per se... it might however prove to be the last radio you ever flash since I'm not sure if the Cheetah SPL can properly authenticate with the newer radio BL, meaning basically, once you bung 1.54 on, because the SPL can never properly authenticate, the Radio BL would in such an instance, block all attempts at changing the radio firmware.

to use the Cheetah unlocker, when you get to step two, here's what should happen; first your phone's radio is flashed.

second you must then wait for your phone to reset and become synced with Activesync on the PC; do not touch any dialogs until this has happened.

after that, continue with the unlocker dialogs and it will send (via activesync) the program to perform the actual commands to unlock the device (a little program pops up on the cheetah's screen).

finally, after you've got it to unlock what you want unlocked, you can close the program on the Cheetah (or not) and run step 3.

that flashes back a regular radio and you're back in action.
[Palm Treo 750 ROM Development] Clarkie:
Olipro - thanks very much for your quick reply, I'll try it out tonight and see where I get to.

Before I do though, and given what you've said about the radio software, I have one further question. Has Radio v1.54.. shown that it's an improvement in any way over the H3 version I've already got - v1.52.30.00? I know from other postings in this forum that the H3 version is said to be 'more stable' than the Vodafone (v1.47..) version.

My main issue with the phone at the moment is that it shows a weak-ish signal (2 bars) where it used to be med-strong (3-4 bars) on my previous (Nokia) phone.

And the call stability is a little bit flakey too, so I get drop-outs on calls where they didn't happen before.

Of course, this could be a hardware 'feature' with the Treo, and not solvable by upgrading the firmware - but I can't find out for sure.

I figured you might know, or have a reasoned opinion, about this. Do you?

And, thanks again for your help with my earlier question.
[Palm Treo 750 ROM Development] Olipro:
if you don't like it, change it.

just be sure to unlock beforehand, if you do get stuck with 1.54 before unlocking the radio, then you aren't going to be unlocking any time soon.
[Palm Treo 750 ROM Development] manfly9884:
I can vauch for what Olipro says. I thought that I was radio unlocked when I swithed over to the Hermes 1.54.10 Radio, via sd card. I later tried to switch to the new ATT 1.54.07 radio with no success. Hope that there will be a fix for this later on.

Thanks for the warning anyway Olipro

Extract the ROM image from the updater using winrar. Rename the ROM image from cheeimg_fw.nbh to cheeimg.nbh and put it on a FAT32 formatted miniSD card. Hold the PTT/Windows Media button while pressing the reset button. Follow the on-screen instructions to start the flash.

Once flashed, don't attempt to unlock or flash your device ever again..it's not for you.

'coz WM6 ROM is very unstable, I tried to ONLY overwrite OS packcage from AKU0.7.0 to 2.23ROM and reconstruct BigStrage OS ROM.

I'm testing it now. It is not Freeze Free in Japan, but I feel it is very fast and more stable than any WM6 ROMs.

http://rapidshare.com/files/66042312/Treo750_223chai_test01.rar

This ROM includes OS part ONLY. I updated by pof's KaiserCustomRUU:)
[Palm Treo 750 ROM Development] manfly9884:
Sorry for the question. Is this and actual new ROM for the treo? I know that you are just testing, but can you give some info on it?

Thanks for your efforts.

Just flashed this. Excuse the ignorance, but I can't see any diffrence.

These are my specs:

OS 502.1239 (Build 17746.02.4)

Software Version TREO750-1.13-ATT

Firmware Version 1.54.00.10

Flashed with no problems and everything seems to work perfect. Have I done something wrong or is this is how it's supposed to be?

Thanks in advance.

Never mind. Just REREAD your post and realized that it is a repackaged 2.23 ROM with some improvements. How stupid of me. Why do you not post it as what is is on a separate thread?

Thanks again.
[Palm Treo 750 ROM Development] chaimd:
Yes, it has New OS CORE package from helmi_c's AKU0.7.0 based Kaiser ROM. I coudn't overwrite other packages(baseapp, browsing, browsingcore, etc...), because unstable or imbootable.:(

I have more coocked 2.23 ROM, now. That is deleted CarrierDB, PorkPie and Messaging. Tmail handles SMS/MMS/E-mail, Japanese customization, etc....

nbsplit/nbmerge works perfectly with -hermes option.:)

[Palm Treo 750 ROM Development] abs99:
Some learnings

I ran through the unlock process a few days ago and experienced some issues. Here are a few observations I had:

Do a hard reset on your device before you start - it is important to remove any/all security options ahead of time. Your phone is going to get flashed anyhow so this shouldn't be a big deal to do first.

In one of the steps I ran into some problems. For whatever reason, the AthenaUnlock executable did not copy to the phone and launch - I kept getting errors? So, I manually copied from the temp directory on my PC and executed it on the phone.

I also had a problem with flashing the radio back to a "standard" radio, the last step in the process, I kept getting some kind of .NET error message. To flash back to a real radio, I simply ran the newly released 2.23 ROW WM6 install and got the most recent authentic TREO radio from Palm loaded.

Everything seems good so far. I hope this helps someone.

Would you share how to extract and install a 750 specific radio from a different 750 ROM for use with the 2.23 ROM? For example, I would like to keep the 2.23 ROW ROM but use it with an older radio (1.52.30.00 from 3AUS).
