For all Nokia 6101 owners

[rafiki6]

Do not and I repeat do not hesistate to take my advice one this.

To all those who own a Nokia 6101 or 6101b with v3.38 firmware and above(mostly in Americas) do not try to unlock your phone using a calculator now. If you hardlock it ofcourse you must use a box to unlock it, and chances are you will hardlock it. The reason is these phones have been changed in there calculating algorithim by Nokia ever since these firmwares came out. If you are able to unlock it then you are one of the very extremely few lucky people, becuase this change did not happen to all phones, only the ones that have recently come off the production line. If you do hardlock it hard luck. Otherwise I am warning do not try, until it is posted as an option in the unlock calculator you use. And be warned, it makes a difference whether or not it is a 6101 or a 6101b. 6101b has modified hardware and firmware for the Americas. If you are succesful please post the settings you used inorder to unlock your phone, in an unlock calcultor.

[mestrini]

this has been in our minds for some time since we have a lot of posts from members mentioning their difficulty to unlock that particular model and the strange messages received upon entering a "correct" code

now, what grounds you have to claim that? inside info?

let us know so that we can try to explore this idea more and/or make this thread sticky

cheers

I cannot be absolutely 100% positive that this is what has happened, but from my own experience unlocking this phone amongst others, I have compared it with nokia 6101's of v3.34, and the algorithims did not match. It is unlockable with a box, becuase ofcourse youi reflash the rom. But using a calculator, it will be nearly impossible becasue it seems that Nokia is now using a new locking system, in which the IMEI, which ofcourse determines the first three numbers of the unlock code or the "Phone Lock" do not correspond the old calculting method. According to one of my pals who works for Nokia Canada in New Market, they are using newer upgraded dongles. He may be BSing me or not, but it seems to be true becuase from my own experience anything under v.3.38 is unlockable. I and a group of friends are working on updating the calculating method to be compatible with new second version or third version DCT4 phones. I am doing it to be able to figure out how nokia is now locking their phones. This new change will affect all Nokia S40 V2 and the newer V3 phones programmed ever since August 2005, not just the Nokia 6101. So for all who are unlocking be wary of this change. I suggest you take my word for it, but I dont guarentee that I am 100% correct.

can you explain that
does it mean you know where to find the algos inside the firmware?

[rafiki6]

Sorry for the late response. No that is not exactly what I meant. The only way you can read the algorithim right now that I am aware of is by using the original locking dongle and unlocking software for the current phones. I have tried doing it by reading and comparing the codes using a box, but to no avail. Otherwise, it will take a while to figure out the algoritihim and implement it in a calcultor. I am discussing it right now with my pals at Nokia. They themselves are not allowed to know how the program calcultes and locks but just that it locks and how to use it, so when they figure out the complete 100% truth, I will get in contact with you and tell you guys. If someone else can figure it out before me that would be great. All I can say for absolute sure right now is that the phones algorithim has been changed, this has occured to All PHONES after AUGUST 2005, and will be seen in many new Nokia phones as well. I seriously discourage trying to unlock it once again, so you do not hardlock your phone. And Mestrini, I will PM you when I get more accurate techincal details so you can announce it to all the Nokia Free community.

[rafiki6]

I Have read throught out this section of the forum, and it seems that there are a few people with version 3.39 locked to T-Mobile who were able to unlock, but their firmware was dated July 25 2005. If the Users could please post their firmware and information in this thread whether or not they are successful at unlocking.

Post it by:

Firmware version (the first thing you get when you press *#0000# on your phone)
Version

RM-XX

then post ur unlock settings if you are succesful

Much Thanks is appreciated

[rafiki6]

Thank you for your reply. I have noticed two trends and this is noticable all over internet forums. The two unlockable phones, that seem to go smooth are v3.39 TMobile , and 6102 or 6102b from cingular. ONe more note my information has been confirmed by my friends at Nokia. I would just like to make a correction to what I said. The firmware date is not what determines your phones unlockability but its production date, and firmware version. In order to see production date of your phone enter the code *#92702689# ( the warranty menu) or it should be on the label that is stuck on the side lid of your phone's box, or under your phone's battery, depending on your carrier. PLease DO NOT AND I MEAN DO NOT edit any info in this menu(although you should not be able to) or else you will void your waranty. When you enter this menu it should read "Made:" as the second item. The Manufacturing date is written mmyyyy. Thanks!

[mestrini]

mmm :???:

i'm finding it hard to understand how the production date has something to do with algos (supposedly inlcuded in firmware)

i think it should be cleared if we're considering 6101 or 610x models in this study, because between models firmware versions can have different dates

[fatboymal]

The firmware date is not what determines your phones unlockability but its production date, and firmware version

This suggests Nokia changed the Firmware Version but not it's Firmware Date, which would be curious, to say the least.

I have unlocked hundreds of 6101 and 6102 since Oct 1 2005. Whilst this obviously does not mean they were all of a firmware date after Aug 05, it is a reasonable assumption that many of them were.

The message "Phone Restriction On" is a puzzle, and there is a reasonable number of failures. I can do a straw poll of the failures to check the firmware date/version of the failures & successes though....will check a few and post back. If I have a success with V4.10 then I guess we will know that this thread is barking up the wrong tree.

It also occurs to me that the first reported case of "Phone Restriction On" was prior to Aug 05

yep, not common in nokia's history and not programmer wise

Agree with Mr. mestrini, not very wise from programmers side. Leads to confussion.

Indeed. "Phone restriction on" in a July 05 firmware, v 3.39.

You guys are correct in that it is not programmer wise or logical in any way, but this whole phone seems to be unlogical. To be honest with you the reason I do not doubt it is because the phone seems to always have a different outcome, and maybe that is where the confusion occured. I would like to add a note though. It seems also to differ from country to country, which suggests once agian, that maybe Nokia has changed the MNC and MCC for these countries. It would deffinitly change the unlock codes since the second or third part of the code is what is affected by the MNC and MCC. I have also been able to unlock several of these phones, but it seems that a trend follows with every certain group. I havent been able to do any in Canada v3.38 from Rogers, with codes and always resorted to the box. The 6102b from Cingular is unlockable, and I have dealt with many of those, and man are they easy. The people who have had trouble with unlocking most probably did something wrong. The 6101b v3.39 from T-Mobile seems to be on and off, but I have noticed it differs from shipment to shipment of phones. The 6101 from Europe is a complete mystery, and seems to differ from country to country, as with my experience, and the non-OEM 6101, I have no clue, because it obvioulsy doesnt NEED TO BE UNLOCKED!! :lol: So I'm working my butt off here guys, and I hope my efforts avail to something!

[EdgeCrusher]

Indeed, the issue looks interesting. Here 6101s are best sellers, but unfortunately none of my friends bought one (everyone is fine with their great 1100, their SE an their motorolas) and I'm very happy with my 3120.

If I find a 6101 that needs to be unlocked here, I will post here.

I haven't had a problem with these.

Nor these.

What serial do you use?

[rafiki6]

Interesting fatboymal, I have had an absoulute struggle unlocking these via code. The Canada versions, I use the MCC and MNC of if I recall correctly
30720, which is for Rogers Wireless Canada. In the end I have to resort to using an unlock box. I have tried several different settings, and in every case I would back up the phone's firmware, and reflash it if it became hardlocked. The settings I have used in trials include, Asic 2 and Asic 6, Asic 2 and Original, Griffin New, and Griffin Clip, each with no avail. I used the same MNC and MCC every time. By the way the only providers who offer this phone in canada are Rogers Wireless. Oh and in regards to the European versions, I have only dealt with 10 or 11 of them and have had a good success rate, which is 9 out of the 11 phones. So the European ones are no big deal, but I am still considering them a mystery, because of the two I could not unlock.

[mestrini]

there are several issues with Canadian providers that have been covered in the forum (one provider bought another and it's hard to know which MNC is used)

and Griffin serials were blacklisted more than an year ago

:-?
Well I disagree, here in France I have more and more troubles to unlock this 6101 model. Last year I could successfuly unlock 100% of them, but since more recent versions, I always get the "sim restriction on" as an error message.
Still using Asic2 + Original.

Did someone ever try a different phone type (asic): 6 instead of asic 2 (+original as box serial) ?

I'm desperate with this model...

did you check if they were not unlocked despite the error message, it happens more and more frequently

[schpuns]

:razz: Of course :)
Unfortunately they were not...

Then try code +7 too
