[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
You can actually downgrade the device, but it will get bricked as anti-downgrading is also implemented on the bootloader level.
[Kindle Fire HDX 7" & 8.9" General] r3pwn:
Yes. I stated that. Did you read my post fully?
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
I must admit to not having read the last sentence. I'm sorry.

I wanted to stress out that you can actually start a downgrade even from 4.5.x. We could exploit this if there isn't any signature verification on the ota archive after the device reboots into recovery.

Do you have any idea who should I ask for a recovery bin dump? Or maybe someone already knows if the signature check is only done in android, before rebooting.
[Kindle Fire HDX 7" & 8.9" General] r3pwn:
It's okay. I know a downgrade from 4.5.X is possible, but people would then need to intercept the traffic by sniffing for a link through logcat. Only then, they could mass-distribute the rollback file from Amazon and hope that the bootloader exploit has not been fixed.
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
I don't think logcat would provide any usable info. I have suggested multiple times and even provided a pretty complete guide for sniffing the actual http traffic.

But I wasn't speaking of the downgrade that amazon provides. I was referring to a experiment that I did to bypass the version check that is enforced at the Android (before rebooting). I managed to flash a 3.2.6 image, but I got a brick as the sbl1 from 3.2.6 has a lower version number. I can bet that the 3.2.7 ota that Amazon provides for downgrade actually has both the build number and the sbl version number higher than the public 4.2.x.

If the recovery doesn't check the signature of the OTA we could do the following:

- provide a bogus image with a higher build number so that it passes the version check

- swap the checker binary from the ota with one that swaps the ota with a valid (signed one) so that it will pass the signature check

- while the android framework is verifying the valid ota swap it again by adb with a crafted ota that has the latest bootloader and kernel so that it can boot

- after the signature check passes the device would reboot and start flashing the crafted ota

If someone would provide a dump of the recovery partition we could disassemble it and see if it does any crypto signature verification.
[Kindle Fire HDX 7" & 8.9" General] r3pwn:
It doesn't do any verification of any sort AFAIK. The only verification is done in recovery mode, and that is done before any binaries of any sort get executed. Also, using the newer bootloader on an older boot image would result in a bootloop, plus you wouldn't be able to install twrp.
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
I must contradict you. I have actually managed to re-flash the 4.5.1 ota over the already installed 4.5.1. The complete story is here.

A build number check is enforced at the os level, before restarting. It first extracts build.prop and checks the device type and the build number. If these checks pass it then extracts META-INF/com/amazon/android/check-binary and runs it. This is before any signature check is done, so you can replace check-binary with whatever you want and it will still execute. Unfortunately it executes as the user of the ota app, not as system.

What I did is to replace check-binary with a shell script that replaces the ota that is currently being verified with a signed ota. By providing a signed ota everything will be fine and a reboot to recovery will be triggered.

As I stated in my previous post, an idea would be to replace the signed ota with a crafted one that uses the 4.5.1 bootloader and kernel, but with userspace stuff moded to provide root. As long as the recovery doesn't use the certificates from /system/etc/security/otacerts.zip to verify the signature once again this should work and enable us to flash an unsigned ota.

Also, regarding the bootloop, if you flash a bootloader chain with a lower version number one, the device doesn't bootloop. It doesn't even get to execute the first stage from eMMC (sbl1), let alone to boot the kernel. You end up in QHUSB mode and no way to get out as we do not have the required MPRG for getting access to eMMC. My device has been in this state since Christmas as I didn't have the time to sort out everything for getting a replacement.

I bought it from amazon.co.uk and someone else delivered it for me in my country (Romania). Now I am stuck as I have to provide a UK address to which Amazon will deliver the replacement. I did a bit of research regarding parcel forwarding services but, unfortunately, I didn't manage to find any cheap, reliable ones.

So, if anyone can recommend a UK parcel forwarding service, please shoot.
[Kindle Fire HDX 7" & 8.9" General] r3pwn:
It still does a signature verification in recovery(with keys stored in the recovery itself, I believe), so flashing an unsigned zip (or bin, whichever) will result in an error from recovery followed by a reboot.
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
Are you 100% positive about this? Maybe there's still away to get around it. Could you please provide a dump of the recovery or know someone who can? I would like to disassemble it and see if there is something I can do.
[Kindle Fire HDX 7" & 8.9" General] r3pwn:
I don't have the device, I'm just stating what I know from just a general knowledge of android devices as well as how well Amazon protected their previous models.
[Kindle Fire HDX 7" & 8.9" General] p1gl3t:
Ok, so if bypassing the signature verification won't work, how about sniffing the downgrade ota. Do you know if the ota app uses a hardcoded ssl identity for the server? If not we could do a mitm and get our hands on the zip.
[Kindle Fire HDX 7" & 8.9" General] r3pwn:
One of my other replies had suggested that. Shouldn't be too difficult.
[Kindle Fire HDX 7" & 8.9" General] johim:
You can return it via regular post. Amazon will refund the shipping costs.
[Kindle Fire HDX 7" & 8.9" General] bsdnix:
Can you please explain the procedure how did you manage to flash 4.5.1 to 4.5.1, because I am trying to do the same on 4.5.5.1 and it gives me an error that it is lower version even though we are talking about same version of the rom...?
[Kindle Fire HDX 7" & 8.9" General] r3pwn:
I didn't. I never had an HDX.

Running a Cingular 8525/Herm100 on Black 2.0. On all WM6 ROM's I have been able to send and receive, it just gives me an 'error synchronizing' message whenever I try and do it manually. Everything eventually goes where it is supposed to though.

Was hoping this would fix that, but still works the same.
[8525, TyTN, MDA Vario II, JasJam ROM Development] simon_darley:
using wm6 black 2 on telstra australia with latest radio. worked on all accounts including lvsms.

so no "problem" here (once i got the settings and manually entered them, tweaked around and learned the hard way with hours of work).
[8525, TyTN, MDA Vario II, JasJam ROM Development] austinsnyc:
My 8525 also works perfect sending and recieving MMS I have entered the Server settings so many times now i know them by heart sometimes i do have to play with the settings either changinf the port number from 80 to 8080 and changing it to use the internet or My ISP to send them.
[8525, TyTN, MDA Vario II, JasJam ROM Development] JudgeDredd67:
I too suffered from the Sync Error message and could not get MMS to work. But I ran the CAB posted at the top of this thread and it now works. I tried everything and every setting that was mentioned, I tried every cab file and every fix I could find. (I know the settings by heart) Now for the big new, once I ran the cab the only thing that I could see that it changed was the last setting of kb's. Before the cab and what everyone said to set it at was 300 but after the cab it is now set at 600. I don't know if this is the change that fixed everything or not but I can tell you that now my MMS does work on my Cingular 8525 running the latest LVSW/26.

[8525, TyTN, MDA Vario II, JasJam ROM Development] pvs:
FWIW, I discovered I was having a problem with sending MMS today. I upgraded to Black 2.0 a couple of weeks ago, but I don't typically use MMS, and so I never discovered this problem before. I found this thread thru Google, and dowloaded the cabfile noted at the top. But I didn't install it. Instead, I took some hints from the name.

On my phone, I had already set up two non-proxied ISP accounts on my 8525 ... wap.cingular and isp.cingular. Of course, I also have the MediaNet Account that uses the proxy. I typically have my phone parked on the ISP account, and that's where I was having this problem.

Looking at the name of this cabfile, I decided to try the MediaNet (proxy) Account next. That wouldn't work either, failing continuously. So then I set my phone to use the wap.cingular (no proxy) account, and bingo, it worked.

As Owycx has noted in the second post (above), I DID get the "Error Synchronizing" message, but this message quickly disappeared and the MMS Message was sent out pronto.

So to those (Cingular) users who might be having this problem, you might be able to fix it without installing the cab ... just make sure you're using the following "Connections" settings:

Name: [whatever you like]
Modem: [B][U]Cellular Line (GPRS, 3G)[/U][/B]
«Next»
Access point name: [B][U]wap.cingular[/U][ /B]

Hope this helps,

Also what i have found that helps is go to settings> connetions> connections> advanced> select networks> make sure that the bottom matches the top setting that way it wont be switching networks for different things.

My MMS server is as follows.

Server name:

Cingular MMS

Gateway:

wireless.cingular.com

Port number:

8080

Server Address:

mmsc.cingular.com

Connect via:

My Isp(or what ever you set the name as in your connections)

Sending Size limite:

300K

Wap version:

WAP 2.0

these settings ALWAYS work for me. I never use the proxy settings that come with the cab for cingular for media net. even though i guess i loose some size of the message i can send from 600K to 300K its no biggy to me.
