Thanks for the info - every little helps at the moment!

Firstly, yes - the radio you're running is native to the area and network and so if you're running 1.54.30.10 and it goes duff you should be covered by your warranty so don't worry. Also, it's not certain yet that there is definitely a problem with this radio so don't loose too much sleep. (Most of the problems linked with this radio that I've researched so far seem to be coming from Europe and after rolling back).

As for flashing with the official ROM, that's a decision for you - however in the cases of sudden GSM death, the phone will still boot to Windows and it is still possible to flash the OS and bootloader roms (just not the radio) so if it did go bad with an unofficial ROM on it you should still be able to roll it back - again sleep easy ;-).

As for the problem - the steps you've taken are a good start, see how it goes and keep us informed here.

It may be worth also trying to manually set your band (if applicable on your network). Sometimes problems like this can be caused by issues on the network itself and trying an alternative (maybe a friends) SIM card for a different network or even manually switching the phone to GSM (if available) can "cure" a problem (although it's a pain if you specifically need to use 3G and it's data speeds!).

Finally - to see your full device information you need to enter the "bootloader" (tricolour) screen. Hang on to this information on the bootloader screen as it can be useful if you ever encounter a bad flash.

To do this, hold the OK button on the left of your phone and the power button on the right then press the little reset button with your stylus. You will then see the model at the top with the IPL version below it and then the SPL version below that. To get out of the tricolour screen, press the reset button again. Needless to say this won't erase anything or damage your device but make sure you close your apps and save your data first:D

I'm not running 1.54.30.10 right now, think i'll flash back to that monday just in case.

Since changing my battery back to the original and cleaning the sim card, still having the same problem. Seems to be happening more and more often as time goes on.

I've actually already manually set my band and tried to run without 3g turned on before i posted this thread when i was doing my own trouble shooting, and it didn't help.

When flashing i normally just push autodetect which is why i don't know my bootloader info off the top of my head.

It's a HERM100 running IPL-1.04 and SPL2.10.Olipro.

I'm starting to think it only has a limited time left in it before it doesn't pick up radio at all. When that happens i'll flash the official firmware back on it, and the orig bootloader (not sure how to do that yet, will have to look it up). And see if i can get warrenty.
[8525, TyTN, MDA Vario II, JasJam General] Mikeapollo:
What radio are you currently running? Thought it was 1.54.30.10 or did you change that the other day when trying a new ROM?

*IF* this is the sudden GSM death syndrome then it will progressively get worse unfortunately - but it might not be that (think positive!);)

[edit : removed - brainfart you answered my question] Incidentally, just updated this thread here - Look at post #60, it's a long post but there is a couple of possible things for you to try there (multiple flashing on a "chilled" phone) for users who STILL have some GSM connectivity... Might be worth a go and certainly could do no more harm... The post itself is very technical but just follow the instructions about 3/4 way through the post and ask any questions back here in this thread so things don't get too confused!

In terms of flashing your ROM - when you _really_ feel the phone may die _very very soon_ then it's worth considering flashing it with the latest OFFICIAL rom from your provider while you are able to do a full flash but don't leave it until DHL are at your door to collect it just in case you need some help!

Oh yeah... and finally for tonights post - Rolling back from Olipros Hard SPL... back to the normal, official SPL - Mr Vanx has written a fantastic guide to this here complete with illustrations - That should save you some searching :D

The SPL rollback, of course, should be the very last thing to do before shipping it back under warranty of course tho - just incase you need it in the mean time!

Good luck - and keep us updated - particularly if all works again (or not)xdaforums.com/showthread.php?t=299070&page=32

I'm on 1.43 right now.

So what you think i should do is put my phone in the fridge (minus battery) for 10-15mins, then flash 1.43 a couple of times while it's still cold, and see how that goes?
[8525, TyTN, MDA Vario II, JasJam General] Mikeapollo:
Yes. Crazy as it sounds, if the previous radio caused "logical" bad blocks - a combination of a couple of flashes in quick succession with the PLA at a cooler temperature might recover them! (temperature issue came from the data sheet for the chip itself - Apparently more efficient writing at temperatures a minimum of 10C below ambient).

Good luck - let us know how it goes... I've got my fingers crossed you'll have a Hermes with it's wings back shortly ;)
[8525, TyTN, MDA Vario II, JasJam General] ferni:
Last night the phone got worse, i had a missed call, tried to turn the unit on to see who it was and it wouldn't turn on, so i soft reset it, it booted up ok, but wouldn't pick up a signal.. eventually after about 5mins it did, but then it locked up. So i pulled my sim card out put it into an old phone which i'm using for now.

This morning came into work and put it in the fridge for 15mins, and flashed the latest radio firmware on it. Then flashed the latest official telstra rom onto it (getting ready for warrenty). That's just finished, only step left is to put the original boot loader back on. May test it again for a couple of days to see if i can get it to do the same thing on the offical rom/radio before i send it back. Will let you know.

Thanks for your help so far.
[8525, TyTN, MDA Vario II, JasJam General] ferni:
Ok Just another update, only a couple of hours since i flashed it and it's already doing the same thing, losing network, so going to call imate and send it for warrenty. We tried :)
[8525, TyTN, MDA Vario II, JasJam General] Mikeapollo:
We did indeed - Ah well, at least you're covered by warranty :)

Mr Vanx has written a fantastic guide to rolling your bootloader back - complete with illustrations. (repeated for others who've just started reading this thread;))
[8525, TyTN, MDA Vario II, JasJam General] ferni:
Yeah hopefully it gets covered under warrenty. That bootloader guide worked perfect :)
[8525, TyTN, MDA Vario II, JasJam General] ferni:
For anyone who cares, they replaced my radio board under warranty - I now have a new IMEI number. Haven't got the phone back yet to test to see if it's fixed.
[8525, TyTN, MDA Vario II, JasJam General] Kedi:
Did you ever upgraded the Radio ROM ?

Or was it always 1.43.

My first ROM only upgrade.

[8525, TyTN, MDA Vario II, JasJam General] ferni:
Yeah i had tried a few different radio roms before this. I suspect it didn't like being flashed so many times.
[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
I am having same problem with 8525 here in south texas. currently running latest att official rom. I have flashed k 1.30, tnt special, schaps rom in last week and so as 1.41.xx , 1.48.00.00, 1.51.xxxx, 1.54.xx xx rom and all have same problme.

Don;t know what to do?
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
I live in WI and travel to rural areas where there is no 3g. I have experienced this same problem when I loose the signal from a 3g area to a non 3g area as it reacquires the signal. I did all the recommended fixes with bandswitch and activesync but to no avail. However, I did this about a week ago, and my problem seem to have disappeared

Go to advance config>data connections>gprs auto attach

disable it

I think the phone goes beserk when it doesn't find the 3g signal?

Try it and please report back if it works :)

I flashed one of the wm6.1 roms and ended up with 1.54.07 radio and was getting the "modem disconnected" error message everytime I tried to log on to the internet.

I reflashed the original WM6.0 ROM from AT&T and then reflashed my radio to 1.48 (can't go back to 1.16 because of the radio bootloader I think) and then tried to log on to the internet.

That didn't work

But then I made a phone call to my home phone

tried logging on and it worked.

Been working fine since

crossing my fingers and hoping I dodged the bullet, not gonna flash again til ATT comes out with 6.1 then if it acts up even a little I am gonna send it in for warranty repair.

I hope this procedure works for you mate.
[8525, TyTN, MDA Vario II, JasJam General] bucktim:
Not exactly sure where this setting is, the closest thing I could find was to install HTweakC. And now I have auto attach off. I also live in WI rural area, and 3G has been growing. Coming closer my home, and when I go to work it switches to 3G from Edge and I believe this is the biggest cause of this problem. I will let everyone know if this has helped me or not.
[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
Thanks pedro for your suggestion. I will try that and will report back.
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
bucktim, that should work, otherwise, Download and install Schap's Advanced Configuration Tool 2.0.2.0:

http://xdaforums.com/showthread.php?t=359458

You can find it on post #4, the first item under "Extra bonus"

Hit "done" when you have it disabled (instead of "x"), then ok for the device to soft reset. Then check it again just to make sure that the setting sticks.
[8525, TyTN, MDA Vario II, JasJam General] bucktim:
Thanks for the info, I removed HTweakC and installed that one. will let everyone know in a week how it turns out.
[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
I did Disable GPRS auto attach under advanced settings.

Problem seems to have reduced but still persists and I am still getting "the operaiton failed" messages again and again however less frequently than before.
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
Do you have the power and wireless manager icon showing on the bottom tray? The reason I ask is because today, I placed them back on again thinking that the problem has been pinpointed, but I got a operation failed for the first time in a week. I have taken them out again through the advance config settings and am crossing my fingers that this plus the gprs disabled are the keys to fixing our problems. BTW, I am using radio 1.40.30.00
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
Also for the sake of not allowing 3g to turn on by itself by any means, disable hsdpa as well.

start>settings>connections>hsdpa

untick the box or turn it off

unfortunately, this will not allow you to access the 3g connection until you enable it again and do a soft reset. The last letter of your radio protocol should change from "h" to "w".
[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
Did that change today. Lets see what happens.

[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
I do not have battery and power icon on the bottom of the tray. I have disabled HSPDA, 3G, etc all the changes but still getting the opration failed message frequently.

Hope ATT updates their network and tower in my area and that will probably solve the problem.
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
gondalguru, I haven't given up yet....please read and retry when you find the time. BTW, the icons on the bottom tray are fine, they don't seem to turn on 3g or have anything to do with the problems that I have anyway.

eheheh, asarabo try tweaking these settings as it has for the most part solved my problems.

1. comms manager - make sure that there is an "x" on the 3g icon or it is set to off depending on you interface. This is very important as all of the other tweaks below will be rendered useless if you have this turned on. Check out the status of 3g on comms manager almost every time before you make a call just to make certain that it is not on.

2. Phone settings - from the band tab, make sure that the network type selected is gsm. On the next dropdown, select your gsm/umts band specific to your network. Here in the US we use gsm 1900 + 850. Once you have that select ok, the radio will reset itself and search for a signal. Once it does get a signal, do a soft reset just for the heck of it. When everything has loaded, check to make sure that the settings you have selected are still there.

3. Do the activestink hack. Set the schedule to sync for both peak times and off peak times to manual.

4. From advance config, disable "gprs auto attach" Do a soft reset and check again to make sure the settings haven't changed.

5. From settings>connections uncheck "turn on hsdpa" meaning turn it off. To know if this has been done, during startup, your radio protocol should now have a "w" as it's last letter. You can also check this at device information.

6. Check comms manager again!!! make sure 3g isn't turned on. We use different apps and using some may turn this on, so it would be good to check this on a regular basis.

Doing these things have brought my phone back to a usable state. It has been solid now for more than a week, with one operation failed which I think was due to me using IE and not checking on comms manager if I have 3g turned off. I hope this solves your problems with making and receiving calls as well. :)
[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
Thanks pedro for taking time and write detailed instructions. I have done most of the things you have mentioned except number 3 - How do I setup activesync to manual.
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
Here's a great page on how to

http://www.aximsite.com/boards/x50-...sappearing-cf-sd-cards-battery-discharge.html

FYI after hours of messing around with my phone today, I also found

1. The radio rom that I'm using 1.40.30.00 is the most stable for my area. I installed three different radios today and while each worked, I had too many dropped calls or freeze ups with the other radios. If you are to change your radio, please install hardspl first to safeguard your device from being a brick. Here's a great guide by MrVanx

http://www.mrvanx.org/cms/index.php?option=com_content&task=view&id=30&Itemid=27

2. If you are using a bluetooth headset, adjust the bitpool in the advance config app to minimize freeze ups. From my readings here, most of the settings are geared for a2dp headset which I don't have. I have found that the optimum setting for me is 20. With that setting, the dialer is very responsive, and only occasionally freezes up. Bluetooth quality incoming and outgoing seems to be fine since no one has complained to me yet. Play around with it to find what's best for your bluetooth headset. I didn't touch the max/min supported bitpool.

This should cover most of our problems dialing out and ending calls. I hope...
[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
Nothing worked and I continued to have the same problem even after doing the active sync change and so as changing radio roms from 1.34 to 1.54, 1.51, 1.47 and finally keeping 1.48.00.00.

I went to cingular store today and asked them if they can give me a new sim card. They gave me at&t sim card. Since then I think my problme is solved. Today I didn't miss a single call and also all the dialed calls went fine. No error messages or operation failed messages.

My guess is that the cingular sim card didn't communicate properly with the att towers probalbly after some network updates in my area.

Hopefully this problem doesn't happen again. Keeping my fingers crossed.
[8525, TyTN, MDA Vario II, JasJam General] gondalguru:
I was wrong is making assumpiton that my problem has solved.

With new att sim card the same problem persists.

Many times during the soft reset on the initial screen - I get messege NO GSM at place it is supposed to show the radio version and some other digit

May be a hardware problme??

Who knows..

I blame it the problem on the TNT se rom as thats when the problem started. May be I am worng.
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
Sorry to hear that...this happened to me as well, and to solve it, I did this:

1.rerun pof's sim and cid unlocker

2. Reinstall hardspl for safety reasons.

3. Reinstall preferred radio rom. Install hardspl before doing this please.

Well turning autoattach off, didnt fix it. Today I was doing alot of shopping/driving and it crapped out like 5 times in 3 hours. There seems to be no real fix, I want to do a warranty return but I am afraid they will say nothing is wrong and charge me for a new phone. Otherwise it might be going up on ebay, I am sick and tired of calling voicemail to see if the phone is working and to see if I missed any calls.

Thanks for the help guys...
[8525, TyTN, MDA Vario II, JasJam General] pedro2k:
That's unfortunate bucktim. I have a love/hate relationship with this dang thing. Just out of curiosity, how much are you asking for it if your provider doesn't take it back? In what cosmetic condition is it? Thanks
[8525, TyTN, MDA Vario II, JasJam General] mrvanx:
It is quite possible your device has bad blocks?

open up a mtty session with the device in bootloader, run 'info 8' to check for bad blocks....then 'task 2a' to fix them. then see what happens.

Lets wait and see what happens. I love this phone very much and don't want to give up. Meanwhile I will put my sim in my old motorola v400 and see if HTC can repair 8525 outside standard warranty. I did pay for the phone with credit card and I am preety sure that I have one year extended warranty offered by credit card.

Update: Phone has gotten worse, losing signal a few times a day. Called up support and getting a replacement in a few days. Will let everyone know how it turns out. The only damage to the phone is where the ring for the wrist strap is. The metal ring chiped a little of the plastic away I sure hope I dont get screwed the out of warranty charge of $497. I might try to replace the rear covers but have to make sure not to ruin the void sticker.
[8525, TyTN, MDA Vario II, JasJam General] bucktim:
Looks like the problem is the phone is self, got the new/remanufactured phone and havent had a problem at all. The only thing that I can think of is I did drop the phone on the grage floor once, maybe that loosened something up inside the phone??? Anyways to make sure they didnt screw me on returning the old phone I switched rear covers, so they didnt say I abused the phone and I used a hair dryer to remove/save the void sticker.

Randomly lose GSM network

Hi I am having this same problem, it all began I think because I use skype frequently and as well when I charge the phone it gets really hot.

My guess it that at some point this all heat spoiled a chip inside and that why we get this GSM desconections, as well after this error randomly the battery drains in like 10 hours where usually lasted for 3 or 4 days.

I want to think that I am wrong but I have switched SIM cards and still the same, actually yesterday the screen didn´t respond like 5 times and I had to make a soft reset.

I know that the hard reset is useless because I have tried before.

So my only guess is that as I said at some point the cellphone got really hot and some chip just don´t work as it should.
