Baseband Downgrade to .01P the EASY way!!! (update.zip)
Tired of losing your 3G on the new baseband? Dropping signals and calls all the time since the OTA update? Well here's the solution! The Baseband Downgrade to .01P!!
1) rename to update.zip
2) place on root of sdcard
3) reboot into SPR
4) choose Install
5) Allow installation from update.zip
6) Install
7) Re-Activate by dialing *228, option 1
Have fun guys, and remember... BillyGalbreath did it FIRST!
Could this be why I lose my 3G randomly for a day? Then it comes back?
Highly annoying when it drops since I use GV for my SMSing needs.
its possible. however if this happens to you, try putting the phone in flightmode for a second then turn off flightmode. this will shut down the radio and start it backup and reconnect to your tower.
Ok so here is one for you... I've been on the new baseband since it was released... everything was fine until a few days ago, now I notice I've been going into data roaming and my 3G is very spotty... I've re-programmed both normal and roamming and the issue is still there...

I always try that, but it never works. I just have to wait until it comes back.
Perfect. I know for fact I am one of the ones that got worse service with the update. Lost my reception in a few different places now, going back to old. Glad I ran across this.
I have gained a few bars back by downgrading. Wow so much for a good update. You would think they would have got it right with the time it took to release.
I just did the downgrade, and my service improved the moment my Droid rebooted. Prior to downgrading, my service had deteriorated substantially since 2.1. I will give a report at the end of today, for whatever it's worth (just my .02) about any real 3G improvements. I used data all day long (Air1, DroidLive, Rhapsody) and almost never have 3G anymore, and if I do it's never for very long.
Weird.. I have a solid 5 bars on 3G nearly everywhere with the new baseband. The only thing I've noticed is that on my ride to and from work via the train, there's a specific spot (I want to say .5-1 mile in length) along the ride where I go from full 3G to full 1x - but beyond that, reception has been awesome.
Then again, I didn't really have any reception issues with the old baseband either..
1. anyone done this with true success and had it work?
2. can you undo it

I'll be able to post my results tomorrow... Prior to updating my baseband, I was able to get a spotty signal in my office (not great, but at least something). Since I upgraded my baseband, I get NO signal in my office. I just "downgraded" so tomorrow will be a real test.
Prior to updating to the newest baseband, I never had issues with reception at all. Loved it. Updated well, because it was updating. Newest would be better, or so I thought....
Anywho, after the newest update, I lost my reception for about a 3 mile stretch of road going to work. I live in the sticks, but we usually have great reception. Downloaded and flashed the "old" update, reception came back in that area, and all is well. No change in battery, my 3G, or anything else. Still works as usual in all other places.
Okay... I downgraded my baseband this morning and was out of my office all day for nearly 12 hours.
I am 100% certain of two things:
First, the so-called baseband upgrade we got with 2.1 causes BAD data signal.
Second, the baseband downgrade presented by the original poster COMPLETELY FIXES and ERADICATES the problem!!
I only got 1xrtt one time the whole entire day after downgrading. Prior to downgrading, I would get 1xrtt almost ALL THE TIME.
I don't know if all 2.1 updates loaded the new baseband, but I know for a fact mine did, and it destroyed my data signal.
Did Verizon do this on purpose in order to free up channels on EVDO? Who knows. But what I do know is that MY Droid will be getting great Big Red data coverage and those who don't downgrade their baseband most likely will not.
I feel like I'm part of an elite community of Droid-geniuses who are blessed with the ability to figure this stuff out and share their solutions with other like-minded (but technically-challenged) comrades like me. I mean, who ever even HEARD of anything called a baseband? The whole idea would never have occurred to me if my life depended on it!
Just downgraded cause I was having some 3G speed issues, was getting 300kb down and 700kb up speeds, also would notice it going down to a crawl at times when downloading updates from market. Now with the old baseband it has jumped to 1200kb down and 800kb up. So so far so good, I'll give it a day or two to see if this holds up.
Reporting back... I downgraded yesterday and I am now getting a signal again in my office. The signal is spotty, but at least it exists (didn't with the 3P baseband). And, my battery life seems to be much better because my phone isn't searching for signal so much anymore. For me, the downgrade is DEFINITELY a positive!
Can anyone provide another link to the downgrade? I have tried to register on the Black Droid forum and never get my confirmation email (tired about 10 times). It won't allow a download unless registered and confirmed. In the immortal words of Rodney Dangerfield, "I get no respect"

I'm also having this issue but only recently did an actual problem occur for me. When I had the 01 BB, I would get 4 bars of 3G at my house. After the 03 update, I got 2-3 instead, which sucks but isn't a big deal. Lately the last week I noticed that I'll physically drop to 1X out of nowhere despite me always having almost full bars of 3G. I'm contemplating doing this downgrade, if anyone could provide this update.zip outside of the BD forums that would be swell. edit: found this on droidforums: Download basebanddowngrade.zip for free on uploading.com

Finally was able to download the file (Black Droid was able to send an authorization to my gmail address and not my comcast). Here is a direct link to the file if anyone had similiar problems:

Just a quick observation. Been playing with the "old and improved" downgrade and noticed my favorite stress killer "Homerun Battle 3d" is not lagging online as it had the with newer baseband (damn that was frustrating). Warning: If you see shrink57 in Homerun stay away - I am kicking serious butt (just got upgraded from Slugger to Champion. Glad I called in sick to the office today (I'm safe, all my coworkers have iPhones)

Seems like I've forgotten how awesome the original baseband was. I did this update last night, sitting in my living room. Literally didn't move an inch. I was getting -78dBm with the .03 baseband (a great signal), but after I flashed the .01, it improved to -62dBm.
So far, I've seen less drops to x1, though this morning when I woke up, it was stuck on x1 until I did an airplane mode refresh.
But so far, so good. Can't notice any battery differences either.
I have this file now on my computer for downgrading to .01p for almost a week now. Now that I can see so many of you have had succuess that I think I will run this on my phone as I've too experienced weeked 3G reception.

Worst case scenario, you just upgrade back to 3P if it doesn't help...
Seeing as many people question this, i figured I would give a little details about what it is, what it does, who should use it, and why they should use it.
1) What it is.
This is a baseband downgrader. When everyone received the new OTA 2.1 update from Verizon their baseband was upgraded. A baseband simply put, is the radio in your device. It is not part of the system files or the data files. It has its own little home on your device separate from everything else, which is why this works on ANY rom, including non-root stock (note: Custom Recovery is required for installation).
2) What it does.
The basband is what decrypts the radio signal from the towers, and it determines which frequencies the device will listen to for said radio signals. My belief (not proven or researched) is that the new .03P baseband is using the new LTE (verizon's new 4G technology) towers and their frequencies. There are not many LTE towers, which results in a lower/weaker signal for people in less populated areas. On the other side, people living in populated areas (like me, in Houston, Texas) get a stronger and higher signal, with faster download rates because of the new LTE technologies being implemented into the network grid.
3) Who should use it.
If you live in a less populated area and noticed a drop in signal or strength (less bars, losing 3G, 1x mode pops up more often, etc) then you should give the downgrader a try. If the new baseband seems to work better, or about the same as the old one did, then this downgrade is not for you. Only use this if you lost signal strength going from the old to the new.
4) Why they should use it.
Using the downgrader will make your phone use the old frequencies to communicate with the old towers (which there are a LOT more of them) which will boost your signal back up. If it fails to help, or you believe the new baseband works better for you (for most it will) then you can use the baseband upgrader to go back. (You can also use the upgrader to get to the new baseband even if you've never had the new baseband before).
I really hope this helps answer a lot of ya'll questions/concerns about this downgrader. If you have any questions, please feel free to ask! I can be reached easiest on Black Droid Mod
Thanks, and enjoy!

I had the opposite results as Fab. I went from -84 on the new baseband to -90 on the old baseband so I flashed back. The strange thing is that on the old baseband I got between 1-2 bars of 3g, but on the new baseband I get 0-1 bars. Speedtests confirm that my 3g connection is slower on the new baseband (however not by much). Very weird.
Edit: I flashed back to the old baseband and now it's showing -84 for that. Apparently it's just normal fluctuation. Speedtests are still showing the old baseband is faster. I'll try out the old for a while and see how things go.
Someone over on the the CM forums mentioned that people at his work that own BBs and unrooted Droids were suddenly experiencing the same thing with signal strength... while the unrooted Droids would make sense for the baseband, not sure about the BB...
Could this all be a network issue? Maybe Verizon is working on the lines getting ready for LTE and it is causing issues?
I downgraded the baseband this morning when I got to work (its been 4 hrs now, I know, not a long sample size). Sitting on the same position on my desk, never being moved, not covered by anything my signal fluctuated from -90 to -87 with the new baseband and I saw the bars fluctuate from 1-3 almost constantly.
Installed the old baseband and the signal is almost identical, though never as low as -90, mostly around -87, -86. Not a huge difference. However despite the signal being just about the same, my bars haven't changed from a solid three for the last 4 hours.
So far I am pleased with the downgrading. I live in West Palm Beach and it is a pretty populated area so I figured downgrading wouldn't change anything but it seems to have helped.
Anybody have any idea why my signal strength could be so similar but my 3g bars not fluctuate?

Downgrading made a huge difference for me. The first day I only got 1xrt once all day long. Yesterday, and so far today I have had 3G the entire time. Without the downgrade I seldom had 3G since going to 2.1.
Didn't really notice much difference in signal with the new baseband, however I was having an annoying issue with the phone not pairing up with my bluetooth after charging. Downgrading seems to have fixed this, so that's a plus.
To add my experience I have to say that it works better.
My location is Queens New York.
Usually when I go visit the parents my signal goes crappy because they live in coop buildings . This makes surfing the web no good.
With the downgrade signals were much better and I was able to get surf at a nice speed.
I finally snapped and did this - the drops to 1x seem to have completely stopped, which is all I really needed. Odd, though. I wonder when the 'new' baseband is going to become more useful again.
If you have Rom Manager the new baseband is available there. If not do a search here Fab posted a thread on the new baseband when it first came out. There should be a link there...

LOL... (BTW don't know if it was intentional but nice Stephen King quote)... do you have Rom Manager? It is available there, and I believe you don't need the paid version to access it...
