This OS is for the 8800 model only and will work on any carrier's 8800 model

Download Link: (updated link 04/01/08) https://www.blackberry.com/Downloads...5E712BC8380F5A


Instructions for installing:

1. Make sure you have the latest version of Desktop Manager installed. Currently, the latest version available is 4.3 and may be downloaded here: http://www.blackberry.com/go/softwaredownloads

2. Download the above file to the PC then install it to the PC by running the file you downloaded.

3. Locate the vendor.xml file and delete it. It is located at C:\Program Files\Common Files\Research in Motion\Apploader

4. Plug in the BlackBerry and open Desktop Manager. You should be prompted to upgrade.

The process takes about 45 minutes to an hour depending on how much data you have to backup and restore during the process. Once it's done loading the new OS it will reboot (it may do this twice during the entire process.) You will see a white screen with an hourglass for up to 20 minutes at a time while the DM says "waiting for initialization." Don't unplug from the PC & Don't remove the battery unless the spinning hourglass has been there for 30 minutes or more. If the hourglass has been spinning for more than 30 minutes continuously you will need to wipe the device with JL_Cmder (close out of Desktop Manager during this process.) You will then end up with a white screen with small icons and an error code number like 507 or 543.

If you end up with a white screen with small icons and the number 507/543, simply connect to DM again and run application loader again and it should load the OS to the device.

Thanks. However your link is wrong (the link points to TIM Brazil, which has an older version).

This is the correct one:

**link removed, not working**

Thanks Phrozen and very sorry. When checking I've make a mistake, but the Mediafire link is corect.

OK, any thoughts on the new version? Any noticeable changes? I've got it downloaded and ready to go, just checking in for any showstoppers.

I already found 1 bugfix: I'm on BES and deleting opened messages from the handheld didn't work with 4.2.1.179 -the message would still display in the list.
This version doesn't have that problem

I am Sticking this and adding instructions... thanks for the post!

The link in the 1st post works now but the same error as before in the 2nd

Thanks =)

Using the above link I get 8800M_PBr4.2.1_rel179_PL2.3.0.85_A4.2.1.108_TIM_It aly.exe

is this really the latest version? my 8820 shows v4.2.2.169

you have a completely different device with a different OS. The OS released for one has nothing to do with the OS released for another.

yikes, thought the 88-- shared the operating system, have to watch more closely with the models i guess

ok so now its showing the .179 when you go to the link. has the new version been taken down?

Hmmm... I got it down this morning but am hesitant to try it now.

Thanks, bigboy, I have also updated the link in the initial post.

Wow, I think TIM was messing with us for a while there, like their own April Fool's joke.

Did anyone lose the ability to sync tasks wirelessly through BES on this OS?

Does A2DP work on this one?

Two employees at the office will be pleased for an upgrade. Just upgraded some of our 8310's to 4.5.0.10 leaving the rest of the staff drooling!!!

I am assuming that I will lose the Chinese Language support with this version ??

You will if you load this multilanguage version.

There might be a way to move the Chinese language cod files from your current CJK OS version over to this one... and modify the alx file to install them. Let's see if anyone knows.

If not, i would the slight upgrade would not make difference, keep the Chinese you have now if it is required.

Thanks JSanders. I dont mind losing it but like you said, if there is an option to keep it, I rather keep it. I guess I can always wait since I am not sure if I will stay with the 8800 or move to the new 9000 series when it comes out.

I upgraded my 8800 from 4.2.1.101 to 4.2.1.115 (I skipped 4.2.1.108) last night. Everything went fairly smoothly (no hair raising or nail biting) with the following minor exceptions:

- lost all my profile settings (oddly enough I don't recall that happening with previous upgrades, but maybe I hadn't customized it as much before).

- all 3rd party apps migrated over but [as usual] I lost all registration keys and settings, and had to re-enter them. Not a surprise once you know and expect this. Custom themes did not break.

- had to reset TCP APN (as usual since I have a Cingular phone, it loses the Rogers TCP APN info). No surprises.

- temporarily lost SMS detection in BOTH Blackberry Alerts and Pocket Day Pro. This one had me a bit worried, but after a few soft boots and battery pulls, both started working again.

- changing settings in WGarage Reverselookup and AutoLock (both of which reside in Options, rather than being icons on the BB desktop) caused Options (and the phone) to lock up. This happened on my last upgrades too; powering off using the power off button recovers from that but it takes a few battery pulls to fix it permanently. Not so bad if you expect it or are used to it from previ
