    And you GENIUSES have provided no solutions, just a lot of verbal abuse. I did revert the 10.3.1.1779 update from the cellular provider that screwed up my Z10 doing what I described. However, yes, this does not work if the phone is flashed with a beta. It did not work on mine either. I'm stuck on 10.3.2.440.
    So you didn't read the thread, then?

    You're right it does not work. Tried it last night. So, how do you revert a BB phone to a prior release?

    If you're on .500 or .680, you can't as BlackBerry blocked downgrades in a portion of the NVRAM that nobody (other than they, I suspect) has a means to erase.

    Rule #1. Don't install a beta.
    Rule #2. Do research before ignoring rule #1.

    I read it. Basically, you all say it's impossible to revert an OS on a BB. Nothing is impossible. BB just makes it very difficult.

    It's not impossible, if you aren't on this OS.

    But, the OP is on this OS.

    We're gonna say it's impossible. What are you going to do to get around the block list?

    Rule #1 - When phone bricked - you try anything.
    Rule #2 - Most of the advice here is more opinion than fact and are exercises in ego.

    NVRAM is called that for a reason.

    The security model on BB10 is extremely solid; despite a couple of years of time to break it nobody that I'm aware of has done so. You can force-load an unsigned (or non-validly signed) image but the loader will not execute it.

    Therefore the only answer other than for BlackBerry to release a tool that erases that NVRAM block (very unlikely as it would make it possible to undo the theft protection in 10.3.2) is for someone to either break the security model in the bootloading sequence or steal BlackBerry's signing key.

    The first has been the subject of plenty of attempts and the latter is probably, given that it would compromise EVERY BB10 device ever produced all at once, the most-guarded piece of intellectual property that BlackBerry has.

    Exactly. Like the blue light special, only BlackBerry can release something that would re-write the nvram values. Why would they though? This is their plan to make the devices more secure.

    Wow. Just wow. Dude, seriously take of the blinders and the earplugs, and stop giving wrong advice. There is nothing the OP can do to downgrade...what are you missing here?????

    OP.... sorry, but you're stuck at 10.3.2. Period. Make the most of it andove forward, and hopefully your troubles will get sorted out with an update.

    I've worked with non volatile RAM since 1985, good at assembly coding, and I have the Z10 schematics.

    But, I do not want to downgrade the OS. I just want a patch for the Z10 that fixes the red LED flashing 11 1111 or 11 10101 when you turn it off and makes it difficult to restart. This started with an official update 10.3.1.1779 autoloaded by the carrier. The phone was flawless prior to that on 10.3.0. The 10.3.2.680 BB10 loaded now is great. I do not want a downgrade, just a fix.

    I've updated my Z30 STA100-2 to 10.3.1 OS version and my cell network didn't worked .. lots of issues, So I tried to load 10.3.2 Dev OS and still same issues. Now I'm trying to go back to 10.2.1.1927 and getting errors like "This OS version is blocked from device". I tried to use auto-loader 10.2 exe files can still stuck on 10.3.2.500 dev OS. Please help me how can I go back to 10.2 OS production version??? 10.2 was working fine and now with 10.3 , all messed up

    Why don't you downgrade and prove us all wrong, genius?

    It's unfortunate, but, you are not alone. Not everyone is going to post and be reminded that "they" screwed up by not reading and paying attention to post. I've received about 6 emails from members on here asking for help to downgrade. Not happening. After the rants were over, I reminded each one that the disclaimer was posted more than a few times and if the OS they were utilizing was that good, they never should have upgraded. For others, before upgrading, review the threads and understand the disclaimer(s). One actually thought about calling BlackBerry.
    Good reply, thanks. Most of the requests for downgrade advice are, like me, I suspect, reacting to a carrier OTA BB10 upgrade that gimped the phone in some way. Mine was 10.3.0 to 10.3.1.179 on Z10 STL100-3 with Wind Mobile. It resulted in a blinking red LED when shut off displaying a 11 1111 or 11 10101 which means an 11 - OS load failure and 1111 /10101 - Bad device memory hardware. https://chimeratool.com/help/BlackBe...om-blink-codes

    Using 10.3.0 the phone was flawless. So it is either a software problem being mislabeled or a manufacturer's hardware fault that did not appear until the newer release. I had no intention of loading an alpha/beta OS and suspect it's the same for some, if not most, of the others. The security aspects of BB10 are impressive and I bought the Z10 as it was the best HW/SW for the money and I would like to keep using it.

    No hole. Z10 w 10.3.2.680 works fine except cannot turn it off wo OS load error blinking. Have to hold the on button for 10 seconds and often it does not restart. I know another person first hand that had the identical problem and the carrier replaced the Z10 with a Z30 free and no questions asked. I've also found several complaints about this with no fixes in many cases. This indicates this is a known problem and serious enough that it is not acknowledged by Blackberry.

    Anyone have an opinion of what the error is? Boot ROM/NV RAM/EEPROM hardware flaw or OS software mistake?

    This is an BETA/Test OS that "we" are not supposed to have. Blackberry doesn't have to acknowledge s**t when it comes to test OSs. Blackberry is under no obligation to provide any support for unapproved users of any Beta/Test OS, nor is Blackberry required to make fixes available to us. If you choose to download it then you are on your own when it comes to bugs.
