With the release of Opera Mini 5, the Opera Mini Forums have been flooded with newbies complaining that they can’t find the signed versions of Opera Mini or even that Opera has “screwed them” them by not allowing them to download it their un-supported phone.
Actually it’s very easy to download the latest signed or unsigned versions of Opera Mini 5, 4.2 or 3.2 to any phone or PC. Here’s how:
Visit mini.opera.com using your phone browser, You will see a screen similar to the two below.
If Opera recognizes your phone it will display the make and model and offer a version that it has verified as working on the phone. It may not be the latest version, many devices that Opera recommends 4.2 for can actually run 5.0. The default download may or may not be signed and there is no indication whether it is or is not. The default is designed to make things easy for non technical users. If you are a power user click the “Other download options” link to get the long list of available downloads shown on the right or at the top of this post. See the “Select Code Signing Certificate” links at the very bottom? Unless you are using a BlackBerry (which doesn’t need certificates) or a Windows Mobile or Android device (the downloads for these are always signed), you will want to click one of the Code-Signing option links which will take you to the screen shown below.
Using a signed version, if your phone supports it, generally lets you turn off some or all of those annoying security prompts that you get accessing the internet, saving pages or downloading when you use an unsigned version. So how do you get the right signed version? If Opera detects your device there is a good chance the default download link on the first screen at mini.opera.com will give you a working signed version. If you have an un-tested phone or the default version turns out to be unsigned or doesn’t work for any reason, try downloading one of the other versions. I’d start with the “All Certificates” one followed by the “Verisign”, “Thawte and “no certificates” versions, in that order until you find one that works.
So what if you want to download a signed version of Opera Mini to your PC for sideloading? The PC downloads at http://www.opera.com/mobile/download/ are all unsigned and if you go to mini.opera.com with a PC browser you will get redirected to the PC page. The trick is to make your PC browser impersonate a phone. This is easiest with Firefox, follow this link to install the User Agent Switcher Extension. Then switch the User Agent to either the Googlebot or iPhone ones, or better yet add your own phone’s user agent (visit ua.yeswap.com with the phone’s browser to find it) to the User Agent switcher. Now when you visit mini.opera.com you will see the mobile page and be able to download any version you want.
Downloading to a PC only gets you a .jad file however. It’s a text file that contains the signature and other information that tells the phone where to download the .jar file, which is the actual executable. To get the jar file open the jad in a text editor. Don’t use Windows NotePad as it runs all the lines in the jad file together making the next step harder, WordPad works as do any of the many free editors like NoteTab Lite or Notepad++. Once you open the jad file look for a line beginning with “MIDlet-Jar-URL:”. The rest of that line, everything after the “MIDlet-Jar-URL:” is the jar file download URL. Paste it into the Firefox URL bar, hit enter and the jar file will download.
I have tried to download opera mini 4.4 it is ok but the problem is that instead of saving it cancels and the final answer is that the downloaded JAR is invalid.what might be the problem?
Hard to say without more information.
Are you installing by going to http://m.opera.com with the phone’s built in browser?
Did you try all three signed versions on m.opera.com and none of them work?
If none of the signed versions work which phone are you using and what exactlly do the error messages say
Does the unsigned version work?
Pls send or attach a a link to a signed version opera mini 7 to my email. Thanks for your good jobs.
There’s a link to the signed version of Opera Mini in the post. I don’t see any point in emailing the link when you can download or install it from this web page.
Internet without opera sucks?
My nokia 2630 cannot download opera mini it is showing my certificate not on phone or sim. Please what should I do.
You will need to use the unsigned version. Opera recomends Opera Mini 4.4 for the Nokia 2630.
show the page plz
Show what page?
I’v bn using 6.5 version on my sonny ericssom W890i i deletd hoping 2 gt an updatd version whch z nt posibl nw as its only 3.2 vers. whch i’m able 2 dwnload,z there nthing i cn do plz??
Opera Mini 6.5 has been replaced by Opera Mini 7
If m.opera.com doesn’t give you an option ti download Opera Mini &:
Go to http://m.opera.com with the phone’s built in browser
Click “Other download options”
Click “Opera Mini 7”
If Opera Mini 7 doesn’t work on your phone your can download the unsigned version of 6.5 from http://boostapps.com/apps/opera-mini-6-5/ I don’t know where you can find the signed versions of 6.5
My phone alwys tells me that there is no certificate on it.
In that case you have to use the unsigned versuin.
In that case you have to use the unsigned version.
Plz tell me how to install user certificates on my mob nokia 2630
I don’t think that’s possible. If it is I don’t know how to do it.
I have nokia 6300 but it has got some problem of certification when downloading
Try deleting any installed Opera Mini versions and then try to install a signed version. Also, there are three different signed version on Opera Mini 7 and 4.4, try all three. If all the signed versions fail your phone lacks the root certificates Opera is using and you can only use the unsigned version of Opera Mini
Are you familiar with Net10 LG 900G? I am trying to get on the web when roaming. I understand I need something like mini opera to do it but I have downloaded it (version 7 and 4.4) but still doesn’t work. I get message “Check Data Restrictions -36”. This isn’t on point to this blog, but I’m hoping you can help!
Thanks for your effort.
The message indicates that Net10’s agreement with the roaming carrier does not include data. Using a different browser isn’t going to change that.
I would wish down for me opera mini on my 3110c mob.phone , it failed coz of certificate pbms yet I don’t know any and am in of it coz I saw it to ma friend’s nokia2630 wen it was w/c inspired to have it too.THANX am waiting!!.
If you already have Opera Mini installed, try removing it before trying to install the signed version.
Also, try all three signed versions, if they all give a certificate error your phone doesn’t support the certificates Opera uses and you will need to use the unsigned version.
Hi. I cant download opera mini on my nokia 5000d because of certificate problems. What can i do?
If you have Opera Mini installed, uninstall it and try installing the multiple certificate version. If none of the three signed options work you will have to use the unsigned one.
I just bought the LG 900g and a 4g card. Now what i want to know is what is how do i get started on apps? Do i need a certain music app, and do i need opera mini? Sorry, i am just trying to fully understand on learning to get started on apps.
Opera Mini is a better browser than the stock one. You don’t need it but you will probably prefer it. To get started with apps go to an app download site like http://boostapps.com, http://wap.getjar.com/ or http://mobilerated.com and browse what’s available.
Hi,i cant dwnld opera because no certificate give me one solution
i m using opera mini 6.1 in my samsung gt-b7722,i modified the jar file for my screan resolution 240*400,its working good but the browser is’nt download or saving ne file,than i downloaded the uc web 8.2 but the same problem occurs.Tell me wat to do ?
Try using the signed version by modifying the jad file as described in this post. If you modify the jar it’s not signed. Most phones don’t let unsigned 3rd party apps save anything.

Waitin in anticipation for your reply and a feesible solution to my problem with your expertise on this particualr matter
Here’s exactly what you have to do to get a signed version of Opera Mini on your phone:
Go to http://mini.opera.com with your phone’s browser
Scroll to the bottom of the page
Click “Other download options”
Scroll to the bottom of the page below where it says “Options for Opera Mini 4.4:”
Click “Select Code-Signing Certificate”
Click “All Certificates”
Click “Download Opera Mini 4.4”
It that doesn’t work your phone doesn’t support Opera’s signed versions.
I’ve my LG (u8138)with complete user certificate not supporting java apps.pls help me!
The LG U8138 does support Java. What error do you get?
Thank you , i do have an uncertified version but i am searching for an certified version for my nokia 6300 please help me to get one
Read the post it tells you how to install signed Opera Mini versions.
Well here’s the source code of the Jad file so which link should i paste in the ULR:
I did paste ” http://opera-mini-6.5.26955-advanced-en-in.jar/ ”
but not a good result , as i could not download it
MIDlet-1: Opera Mini, /i.png, Browser
MIDlet-Description: Opera Mini
MIDlet-Name: Opera Mini
MIDlet-Permissions-Opt: javax.microedition.io.Connector.sms, javax.wireless.messaging.sms.send, javax.microedition.io.Connector.socket, javax.microedition.io.Connector.file.write, javax.microedition.io.Connector.file.read
MIDlet-Vendor: Opera Software ASA
That doesn’t look like a proper jad file download from Opera. For one thing is not signed and for another the MIDlet-Jar-URL: is malformed as it it doesn’t start with http.
Try this one:
Thank you its really helpfull.

I finally can save pages on my lg 900g. I tried some of the signed 6.1 & got success on the Thawte version. Thanks very much.
I want to download opera mini but my phone say no certificate. Pls help me.
It you get the certificate error with all three signed versions you have to use the un-signed one.
I want to browse operamini in my phone but it tell me no valid certificate please how can get the valid certificate
There’s no way to add certificates to most phones. Try all three signed versions and if none of them work you will have to use the unsigned versions.
can yu plz choose me a rite browser to my nokia 2700c……??
Can you provide me a link of Opera mini 6.0 signed version as it best suits my Nokia 3110c. I’ll be very grateful to you.
The Opera Mini 3.2 low memory signed version does not exist. If by any chance you find it, please reply to this post.
Opera never released any signed versions before Mini 4.0.
Low memory really means it supports the Java MIDP 1.0 profile for compatibility with very old (at least 6 years ago) phones. MIDP 1.0 doesn’t support signed apps.
If your phone was made in the last five years it should be able to run Opera Mini 4.3 signed or un-signed

It sound like your operator crippled the phone by removing the certificates. It’s not possible to install certificates on recent S40 phones like the 2700c. You will have to use the unsigned versions.
I get too many questions to reply to comments by email. If you want replies by email check the box on the comment form. And unless you love SPAM don’t put your email in the comment body where spammers can harvest it.
Hello, friends if u want download opera browser in ur mobile go to this site, m.opera.com and there are many opera browsers for your mobile, N 2700C if u cant download opera from your default browser you can try as your wap pages eg, (dont open browser), > go to web address, >type, m.opera.com and the Opera latest virsion apears enjoy downloading, bye
When I copy the link for the .jar file out of the .jad file it just sends me back to the unsigned version!
The signature is in the .jad file. To install the signed version copy both the .jad and .jar to the phone’s memory card and open the .jad using the phone’s file manager.

when there life there is hope
everything you need is
open mini.opera.com from your default phone browser…
then choose other download options…
there is everything you need here and the signed version are in the bottom that was opera mini 6.1 and 4.3, 4.3 instinct
i want install opera mini 6 by my ‘ p1i ‘ browser with “all certification” but in end of installation “security information” say: component failed security check cannot install.
There is no option ,,all certificates” for Opera 3.2 just for 4 and other.
That is correct. 4.0 was the first Opera mini release to have signed versions.
You can also download unsigned version or signed & your problem will be solved.
Go to end page of http://m.opera.com, you will get it!
Mini opera browser 7 signed
There is no Opera Mini 7, 6 is the latest.
I want to download opera mini but my phone say no certificate. Pls help me.
