Variation on "Cannot connect ...." error

Hi friends,

I don't know if this is relevant, but I will relate my variation. I stumbled onto this tread after typing the quote for my error. The error seems to only come up when I connect through activesynch

I got the error after upgrading my ETEN Glofiish to WM6. My WiFi does work. However, I have the following issues:

1) It seems I need to reconnect and type in my WiFi code on every connection. It has no memory of my prior connection on my home WiFi network.

2) Likewise, it doesn't seem to remember any of my bluetooth connections. I must always input my stereo bluetooth code "000" for each session.

Again, I don't know if these errors are related to the error message. Any wisdom would be appreciated. Please point me in the right direction if someone has insight into the 2 issues I described above.

Regards,

Ed

Has anyone come up with a fix yet?

Has anyone come up with a fix for the dead WLAN yet??
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
I'm afraid not... We are all anxiously waiting, but I'm sure there is a reason for the delay.. Either difficulties, or Pof and Olipro are very busy doing other stuff equally important to the scene.. All we can do is wait.. I'm sure they will come up with a solution, they always do :)
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] Olipro:
Yeah, I think pof's been busy, haven't seen him for a good few days
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] princeasi:
Hey olipro, have you pinpointed how a flash can kill off the wlan like this?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] fabrice1k:
Please dont't forget us... I really miss mi WiFi !!!
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] troyDoogle7:
one of the guys has nailed the fault to the comm manager (perhaps) in the black support rom section. Perhaps there is a light at the end of the tunnel?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
No it seems that the WiFi info (specifically the MAC Address) was overwritten / erased in the eeprom during our trial to fix a dead hermes, and therefore the wifi component cannot initialise itself and hence "dies"... I checked this with mtty tool and indeed it is corrupted. Pof already found the needed steps to do to correct it, but because the eeprom has a checksum at the end which also needs to be modified so that the system doesn't think this is a corrupted eeprom, he needs to find the correct way to calculate this checksum... Pof and Olipro will eventually get it, we just have to be patient and wait... :)
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] rsolomon:
In the meantime, it would be useful to have a backup tool for folks to save their own MAC+checksum info off.....

Richard
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
or ANY info in the eeprom for that matter :)

Hi, I'm a newbuy to the PDA's -so late i guess :( -

I have updated my X01HT to wm6. I'm having the same problem as you guys DEAD WLAN. I press turn on -> nothing happen... i guess it the same issue you r discussing here.. Am i correct?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] KaminaAyato:
I had a similar problem where the Wi-Fi would basically turn on when I told it to but disconnect immediately once it found an access point. I'm not sure if you guys are having the exact same problem as me, but I got my Wi-Fi working again after changing the Device ID which is probably just sheer coincidence.

-Nick
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
@KaminaAyato:

No this is entirely a different problem. The WIFI does NOT even start, because the data it requires in the eeprom (more specifically the MAC address and the memory block checksum) is corrupted/erased. Most likely this block was corrupted/erased during a bad radio rom upgrade, or (as in my case) during the efforts to revive the device and following some methods in the wiki. Pof and Olipro will hopefully post a utility to re-write this block and recover the MAC address and checksum, thus revive the wifi functionality. Just be patient guys :)
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] GenesysLV:
Any new info?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] lknaap:
Any news on the issue yet?

Hi guys,

Is there someone who wants to donate his/her wifi rom dump with mac address to fix this?

Now Olipro and Pof are looking for how the checksum works. I wish I could do this but then again I lost my WIFI completely and dont have the code.

Olipro and Pof do you think its possible to get this fix or will it take a lot of effort? Otherwise maybe its smart for the people with warranty to have their devices replaced.

Wouldnt it be much easier to use an existing dump and all people with this problem use the same mac?

Thnx for the effort anyways.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] jasonchiu:
hey guys i havent been on the site for a while.

which rom causes this? just want to avoid the problem.

hope all goes well soon.

kind regards,

jason
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
@jasonchiu:

this is not ROM related, but rather due to a failed RADIO upgrade or most commonly due to the trials to UNBRICK a device. Read post #55 for more info
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] troyDoogle7:
although a few people may have issues with their radio, most people didn't have the issue util they upgraded to black 3.01 or 3.5
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
@troyDoogle7:

From what Pof told me, this specific problem is NOT related to any ROM specifically. It is due to the fact that the MAC address was erased somehow (most possibly due to bad radio flash or due to ERASE commands in mtty while trying to apply the wiki directions to recover a bricked hermes). The ROM (OS only) upgrades do NOT touch that part of memory, hence cannot corrupt it. The issue you are referring to is different: the wifi STARTS, but either cannot connect to an access point or drops the connection when it establishes it or shortly after. this thread is NOT for these cases

I'm desperate...

[8525, TyTN, MDA Vario II, JasJam Software Upgradin] pof:
we've been busy, sorry for the time waiting, will try to publish something soon.

We can't get the checksum calculated, so finally I think we will publish the same WLAN MAC for everyone, not a neat fix, but will work :)

[8525, TyTN, MDA Vario II, JasJam Software Upgradin] alfiekino:
first i hv to say a big thank you to u and olipro! i really appreciate how u guys helped us...

my question: is it possible to change the MAC in registry?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] belu:
I think it's not possible to change the mac adresse in reg.

If we can do it, pof and oli didn't surch how to calculate checksum :)
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] AgD:
I have my old WLAN MAC (it is in my router configuration), can i use it for the fix?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
Any news?

Hi Pof,

any news on the utility? I can be your guinea pig if it won't brick my device ;)

Thanks

Chris
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] rsolomon:
Is the "read and store old MAC + checksum" approach feasible? I.e. could you make a utility to "back up" one's existing MAC+checksum then restore them in case of corruption? This seems like the best short-term approach, with you guys providing one known-good backup for the already-corrupted people to use. A collection of MAC+checksum *might* also improve our chances of figuring out the checksum....which is probably really a CRC :(

Richard
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] cuboosh:
so whats the status on this?

Read this, it helps

http://xdaforums.com/showthread.php?t=299451

for those who can not be bothered to read the above, here is a condensed overview.

The problem is that your wifi card in your hermes has no mac address, you need a mac address to be able to use ANY accesspoints, its similar to how your phone needs a imei number on GSM networks.

If you think you have a wifi/mac problem goto bootloader/mtty and then type these commands

[task 32

task 37 ff

in the dump search for

[K :: KERNEL] Kernel: EEPROM signature=

if the following lines are the same as below then you have NO wifi mac

[K :: KERNEL] HTC Nand Read!

[K :: KERNEL] Kernel: EEPROM signature=FF FF FF FF FF

[K :: KERNEL] HTC Nand Read!

[K :: KERNEL] Kernel: EEPROM signature Old=FF FF FF FF FF

the wifi mac is in a eprom which is not the same are the rom you flash with o/s

the wifi mac has a checksum which is a signature to say that the mac is correct

the mac is NOT in the registry.

without a mac address and a valid checksum you can not enter a non original mac.

What Pof and Oli have been working on, is a way to calculate the wifi mac checksum so you can choose your own wifi mac, they have been unable to do this currently. As a fall back anyone who currently has a mac address of FF FF FF FF FF and uses Pofs/Olis application would have the same mac as other uses of the application.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] alfiekino:
i tried to do the dump... but i found that the lines come out don't even have this line in it...

Cingular 8525

I have a Cingular 8525 with SPL-1.06, Radio 1.16 and ROM 1.34.502.1

I want to go ahead and upgrade to WM6 but am afraid of the dead WLAN issue. Is there any way that I can take precaution so that I do not lose my WLAN capabilities when I upgrade?

Barely a noob :)

My personal opinion is that after running programs like HTCTweak, Pimp My Black, etc, it kills the WIFI. I noticed that after flashing a new ROM and never running those types of programs, my WIFI is fine. A few previous times I tried those programs, WIFI quit on me. Just IMHO.
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] vp3G:
Those apps just modify reg settings. Within the context of this thread "dead WLAN" means it's been flashed into oblivion, never to come back. MAC address and everything has been wiped out.

Hi,

I almost crack open my Cingular 8525 due to this issue. Okay some mine get the WLAN Dead issue after I upgrade to AT&T Cingular 2.15 ROM I downloaded from AT&T Website. I can't return the unit for waranty because I'm now not in US. Anyway I follow the thread and I have a few info on LAN EEPROM & MAC Address.

1. MAC Address - Definitely needed to enable LAN Adapter, similary to WIFI, we can assign any arbitrary Hex Digit into it. Mostly it is assigned during device manufacturing. It has to be unique to at least the network it is connected to. So you can put something like 00-0D-61-B7-64-6B as your MAC Address

2. EEPROM Checksum. In most casses, EEPROM checksum does not matter, as long as the setting is correct the LAN device will be able to up. I use to manually edit LAN EEPROM (Desktop Motherboard) to enable features. If we know what chip Hermes is using we can find the generic LAN EEPROM for it. The settings tweak are usualy related to Power Setting, Negotiation and Link speed.

I would really like to help on this issue since my WLAN is dead as well. I've got mtty.exe up and I've been flashing my Cingular 8525 to HardSPL7 WM6 a few variants. Let me know if there's help needed
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] chrisvor:
1. From another thread (http://xdaforums.com/showthread.php?t=299451&page=1): the chip is MSM6275

2. also from that thread: have a look at post #20. nitty-gritty details on where the MAC is stored

I have been in touch with Pof and Oli (two of the super-master-gurus in this place) and they said they would help, but it's been more than 3 months now, I dont know if they are stuck somewhere, or if they simply dont have the time....

maybe you can help out.

@laikos: btw, are you greek?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] laikos:
I ran through the MSM6275 Datasheet but seems like that's might not be the chip we are looking at.

TI tnet W1100BGHH MAC - a chip for Wi-Fi <-cannot find datasheet (TI AVX100 Chip)

Maxim MAX2820 WLAN - a chip for Wi-Fi (Transciever)

This is used by HTC Universal, as it is very normal that OEM will use the same part in many products. If there's way to Manual EDIT the NAND flash that will works too. Maybe we can write some instruction on that for temporary soln. Just to get the Wifi up at least.

Well, I'm not greek but I'm frendly ;)

<--snip-->

If this is the correct EEPROM Data we can probably convert it to nbh format and load it at the offset mentioned

Offset: 0x500CD800

Does anyone is familiar with lnbs command? for MFG SPL?

WLAN or WIFI - Who can help?

Ok, first I just want to find out whether the terms "WLAN" and "Wi-Fi" actually refer to different things, or if we are all talking about the ability to connect to a local AP using the wireless network adapter. I don't care about connecting to a data service provided by my carrier, I want to connect to the same wireless router or access point that my PC connects to wirelessly.

Next, this thread is clearly only related to the issue where the wireless adapter MAC address has been stuffed entirely, through one means or another. Everyone happily points this out and says that if you still have a MAC address then this is not the thread for you. My question then is, what IS the thread I should be looking at? I've spent 2 days searching the Wiki and Forums for a thread that deals with the issues I'm experiencing but have been unable to find anything even remotely helpful.

2 days ago I upgrade my Dopod 838Pro to WM6. There were no issues experienced during the upgrade, but since doing it I have not been able to establish a connection to my AP. I have since downgraded back to the shipping version of WM5 in an attempt to get rid of this issue as I had no problems prior to upgrading.

One thing that I have found is that if I change my AP to be open, using neither WEP nor WPA-PSK I can actually connect successfully, however as soon as I go back to WPA-PSK I again cannot establish a connection. I will try WEP next and post an edit with the results of WEP.

Please don't just dismiss this with a "this is not the thread for your problem" remarks I've been seeing. If there currently IS a thread for my issues then please direct me to it, because I haven't been able to find it. If there currently isn't then please state this clearly and I will start a new thread and attempt to find out how many other people are being effected by this type of issue.

Thanks all.

Device Information:

ROM version: 1.30.707.8

ROM date: 12/13/06

Radio version: 1.47.00.10

Protocol version: 32.80.7020.20H

Update:

I have just tested WEP and it works also. Problem only seems to be with WPA-PSK security. Unfortunately I can't test any other APs - my router is a Netgear DG834T with the latest firmware on it. Does the Radio ROM version have anything to do with the WLAN/Wi-Fi/Wireless Adapter in my Dopod? I have no connection issue from 3 other PCs using WPA-PSK, the issues are specific to the 838Pro.

@poorhatsoap....this thread is about Hermes users that, due to some unknown factor, during an upgrade, lost their Wireless LAN programming (also known as WiFi, WLAN) IN THEIR DEVICE. The epromm chip data got erased so wifi won't open, won't turn on from COMM Mgr or any other way, and under properties there is no Mac address. And by using the MTTY program one can verify their device has an erased EPROMM. It's not about users having problems connecting to their router or hot spot, it's about the firmware for the Wireless NIC is gone. Members Pof and Olipro were working on a solution, but, for one reason or another, a solution has not been posted as of yet. Some of us are discussing this on this thread and also in the IRC channel.
