    *BUMP*

    Any progress on this issue?


    I exchanged an iBrick (would not power on) for a refurb iPhone at the Apple Store last Friday and it was already jailbroken w/1.1.1.

    Here is what I did when I got home.
    1) loaded Installer.app via Jailbreakme.com
    2) loaded AnySim and ran it
    3) Connected to iTunes and got "Invalid SIM message" Unlock worked at this point just could not sync w/iTunes.
    4) Loaded OneSim and ran it to revert the AnySim changes.
    5) Put iPhone in Recovery mode (itunes logo) and restored to 1.1.1
    6) Jailbroke w/Jailbreakme.com then ran AnySim again.

    Now the phone boots up and accepts the T-Mobile SIM but whenever the phone goes to sleep for more than 15-20 seconds the baseband crashes when a call comes in or you bring the phone out of sleep.

    I have the same crash logs as others who reported

    1422937 mux: Enter low power mode.
    1422937 mux: Control channel sending PSC command (0 bytes).
    1422941 mux: Control channel received PSC response (0 bytes).
    1422989 reg: Entered low power at 12:41:46 (-480) 11/26/2007 ST (1427)
    1423180 ipc: *** Baseband crash detected! ***
    1423180 rm: reset called with reason modem reset
    1423180 rm: Reset: modem reset
    1423219 rm: ENTER: resetCommon
    1423220 rm: start reset dispatcher state
    etc...

    I didn't know to check the bootloader version prior to running the unlock or virginize but when I run the bbupdate -v to check the bootloader it shows ver 3 now (post unlock and restore). Could i have had the newer bootloader (Ver 4) and messed things up when i re-virginized and it now shows V.3?


    If this truly is a hardware issue then i have to fry the battery or totaly hose the phone so it won't boot in order for Apple to exchange. So how do i explain a second fried iPhone before activation (first one was legit, just stopped powering on)??

    The phone i recieved was a refurb form the Apple Store so i would expect that it was tested and had no hardware issues (I know a HW issue is possible but its unlikely). I can see in the crash log that the problem is with the baseband firmware crashing and I would expect that to be a SW issue since we change this during the unlock period.

    Anyone else having this issue? Should I attempt to restore the firmware again? I've heard its bad to restore over and over again so I've not tried this.

    ...For now i'm back on my T-Mobile BlackBerry Curve 8820 w/WiFi Calling! It may not have a nice graphics or be touch screen but it works awsome.

    Or better reflash all the good nor in the bad iphone!at least you will have two iphone with the same imei!! joking

    Confirm that in my crash report there is no baseband crash,like orcinus.
    yesterday as usual i pointed my wake up call on the iphone,but today i was late at work.
    so now i know that if you don't delete the com.apple.........plist no incoming calls,no sms and no wake up call!!
    i'm going to believe is an hardware iusse.
    the only way for me to change the iphone is to give them back burned,dead.no power on!
    the only problem is that the new one will be locked!!
    Yes, there are differences in the nor dumps here is a summary...

    a) range 00000000-003BFFFF identical

    b) in the good nor, range 003C0000-003C0FFF contains data and lots of binary '00'
    in the bad nor, same range contains all 'FF'

    c) in the good nor, range 003C1320-003C263D contains data and lots of binary '00'
    in the bad nor, same range contains all 'FF'

    d) in the good nor, range 003D0000-003D0FB3 contains all 'FF
    in the bad nor, same range contains, mostly 'FF' but in various locations (9 places)you will see '7D 0C xx yy' where xx yy changes.

    e) in the good nor, range 003D0FB4-003D5A1B contains all 'FF'
    in the bad nor, same range contains areas of 'FF', areas of '00' and areas of small amounts of data, for example '51 01 84 0E 75 01 22...' (this same pattern appears in various locations repeatedly....

    f) in the good nor, range 3D5A1B-3DFFFF contains all 'FF'
    in the bad nor, same range conatains all 'FF'

    g) following this range, i see a pattern similar to c) but reversed, ie. the bad nor contains all 'FF'

    h) the rest of the nor are 'almost' identical, only few bytes here and there that are different.

    i) good nor ends in '6F 5C' and bad nor ends in '08 AB'

    I'm not sure what to make of all this, these phones were bought at the same time, same Apple store, and unlocked in exactly the same way, yet the nor has different patterns...I'm sure folks in the dev team have parts of the nor mapped out, and can maybe make some sense of all this.

    I'm tempted to virginize both phones and start over...but then again, I've spent way too much time with this.

    BTW, with orcinus fix, what continues to draw battery power other than wifi (which can be manually shut off, and maybe bluethooth (which is useless anyway uness you like one of those bugs in your ear). I'm currently trying to get some battery drain comparisons between the two phones. The good phone has been sleeping for 12 hours 25 min from a full battery charge and still shows completely solid (actually this phone doesn't have a SIM card, so mayby this is not a good test, perhaps the gsm radio is not on at all, let alone power save mode) My bad phone has been pretty good with little battery drain for the same period and WiFi off.

    So, I'm starting to conclude that if you do the orcinus fix and manually turn off Wifi, you have the exact same environment as a fully working iphone. battery drain should be identical. anyway to confirm this? Do we know if there is anything else that goes into power save mode, the ARM processor?, I kind of doubt it?

    Btw, It was a breeze comparing the two hex files with Fairdell HexCmp2, great utility but not free, just using the 15 day trial.

    On that subject, BTW... How/where can I order a new comboard? Are they delivered to my country (Brazil)? Is it hard to change it oneself? (My hardware opening experience is limited to installing RAM in Macs). Will the new comboard relock the phone or give a new IMEI?

    Hi Donanado,

    I agree with you about the battery life,reading the forum many people reporting short battery life!
    Right now the problem is not on the iphone is in me.
    I' don't Fuc...g wont this iusse,i know i have it and i dont' wont it!!
    By the way
    I found on this site a dump of 1.1.1 Nor
    Save as to download this link http://lpahome.com/geohot/DBS/DBSgui/tehnor
    Comparing this file (Fairdell HexCmp2) with my Nor the first thing i noticed is the size different,mine is bigger.
    Anyway going on i found that I have a recurrence of 2 byte (always the same=A0) that are not in the one downloaded.
    well cutting all this byte founded every 5 or 10 lines in the hex the result is that my nor result identical to the one downloaded.
    So my Nor is the same to this one but in different location!!!
    i really don't understand the meaning but i was thinking at AnySim.
    Does it patch always the same location or not?
    Did it patched the correct location on my iphone?

    I really can't give an answar!
    can you please report the size of your Nor?
    mine is 4.220.157 byte


    Bye

    Bye
    I understand your feeling exactly, I love everthing about the iphone, EXCEPT this Fuc...g problem.


    the size of my NORDUMP is exactly 4.194.304 same as the one you linked to

    my theory and some experience on repeated bytes within memory dumps, especially when a good memory dump shows all '00' or all 'FF', is that there are some bits that will refuse to change when written too, a sure indication of bad memory...

    Although I would have expected a lot more serious problems with memory corruption than just a power save issue, I suspect there is an area of memory that is only used for saving low-power state data and therefore passes Apple's Quality Check, thus the phones are released to the unsuspecting consumer...any other bad areas in the NOR are probably caught on the assembly line and are corrected...so are we leaning towards hardware issue again? From the posts indicating a replacement COM board works, I would have to side with hardware issue.

    So maybe we should focus on how to get Apple to fix or replace...if we re-virginize the phone, and the phones are not activated on AT&T, how do we indicate to Appple that there is a problem? Or is there a way to completely disable the phone so that it doesn't boot at all and doesn't show any tampering?

    Donando & Derter - you guys rock


    So could we try to overwrite the NOR data a few times with the proper one and see if some of those stuck bits will change over?

    Maybe we can't get all of the stuck bits to change but if enough of them do it might allow the Baseband too load out of low power mode without crashing.

    iPaq have quoted me 84.72GBP + 18.90GBP labour for replacement of the Com Board.

    Given the complexity of the task, it seems like a bargain to me (assuming it fixes this problem).

    I had also been having the same problem with my iphone, lost signal when iphone in sleep mode, when docked it was ok.

    Both my gf and I got our iPhones at the same time, place, firmware and unlocked at the same time, hers is fine mine wasn’t.

    US iphone, OTB 1.1.1. The JohnTool didn’t work for me. Orcinus’s fix worked a treat!

    Thank you for finding and posting this fix.
