That would not justify 10x increase in CPU score...this is more on par with how the snapdragon phones got an increase in CPU score and on Linpack after upgrading to Froyo...which was probably the work of the VFP...we have soem thing similar to "some" extent from the ARM Neon SIMD...which by the look of those numbers seems to be it...those numbers actually look closer to the Nexus S benchmarks in quadrant pro :/

Can you do a Linpack real quick?

Not only is Samsung's updating screwed up, but their customer support really really sucks! Seriously, give them a call!

I know I'm newer here, but here's my suggestion on what Samsung (and other phone makers) SHOULD do:

- Support their product well. Seriously, it's easier to KEEP me than to rewin me. So, good support is a must. Even if the product is meh, if the support is good I'm all for it.

- Release Vanilla software. I'm serious. Just tell everyone how to root and how to install ROMs. If they're gonna be THIS lazy and procrastinate THIS much, they should just let other people do it. I mean, all of the developers on this site seem to be creating stuff better than what Samsung put on in the beginning!

Oh, also, I doubt that Samsung actually reads these forums. That's another thing that phone companies should do: read the forums!

/rant.

A disclaimer: I do like my phone. I love it. Except for it's few problems that Samsung refuses to acknowledge (say, their keyboard missing keys and GPS) and the problems I need to get fixed (Speaker, lol) and their crappy support, it's a great phone and I'm happy to have it. I wasn't into Android phones before (switched from BlackBerry), so I was ignorant of Samsung's blunders. Unless they do something to step it up, I'm never using a Samsung product again. (Ok, maybe it wasn't /rant xD.)

Now /rant.

[Epic 4G General] awesomo4308:
It's all about the average consumer. I'd say most Epic owners don't really care about app2sd or flash at this point. However, if something like Hulu+ or Netflix came out and required 2.2+ then you would find a significantly larger outcry if the typical owner found out his or her top-end phone couldn't play what other android devices could.

Quadrant scores are pretty much as fake as they can get. Besides, does some score really matter to you? It worked incredibly fast with tw to begin with, maybe without it its a bit faster, but just because a score says something way higher, doesn't necessarily mean the TW bloat ware was causing it.

Samsung Intercept and the Evo both come with the "Sprint bloatware" and they didn't take forever for Froyo. The real culprit is the horrible Touchwiz.
[Epic 4G General] themirthfulswami:
There's actually a lot more benefit to having Froyo than just Flash and moving apps to SD cards.. a lot of the refreshes Google is performing to it's core apps require 2.2+. And now that Adobe has released the Air tools to compile direct to Android, Flash developers like me would like to be able to test their apps on their own devices.

I'd like to try installing a custom ROM, but I'm a newb and since this is my only phone (no landline) I really don't feel comfortable with the risk. I guess someday I may have to do it, if this keeps up, tho..

Root and flash new software, its all out there (or in here for u).

Anyways all of u had 30 days with the phone to try it out. If u didn't like it, u shouldda return it. My phone is dope... maybe I got a funny one... but im running froyo... been on it for a month, gps lock down to a (that's 1) meter in under 5 seconds. I have 4g... the phone works great.

I have vista, last active sync installed. energy rom, firewall on or off still the same, deleted the partnerships in my hd

When i connect it, all it does is read the memory card

[EVO 4G Q&A, Help & Troubleshooting] ScaryBugThing:
I've been on Fresh Evo 3.1.0.1 pretty much since July 2010, and I'm thinking of upgrading to Fresh 3.5.0.1. However, before I do, I'd really like to know if there's some sort of custom ROM comparison thread or spreadsheet. When I was looking for a custom ROM originally, someone posted a very very helpful Google Doc spreadsheet that compared the features of the (then) crop of custom ROMs.

While I'm mostly generally interested in a comprehensive comparison, specifically, I've been wondering what the advantages of Myn's Warm TwoPointTwo are, since it seems to be very popular lately.

Is there any spreadsheet or other comparison so I could easily figure out how the current custom ROMs differ?

[EVO 4G Q&A, Help & Troubleshooting] BooDaddy:
Good idea. I have udpated the instructions to include folks that are already rooted.

Honestly, I am not sure. But, if you do have another Evo that has good RSA keys, its possible. You could, in theory, use my directions to get a copy of the keys from one phone and copy them to another phone using another similar and easy Lniux command. The only problem is those 2 phones couldn't be used at the same time. Tee process would be a little similar to cloing ESN/MEID's, so I do not think I would be able to post the command to do so. It would be another simple Linux command to copy the keys you have back to the WiMax parition, replacing the ones that are on the phone now.

If you are running titanium backup, hit the "problems" button at the bottom when you open titanium up, it will ask you if you want to install busybox. see if that helps.

[EVO 4G Q&A, Help & Troubleshooting] willy900wonka:
When is a key not a key? When it contains everything to the EOF

Maybe you should rename RSA_oem.key to end_of_file_starting_with_BEGIN_RSA.stuff . Just saying.

Wana see something neat (whether your nandroids have a copy of your RSA keys) do:

#grep RSA /sdcard/nandroid/HT065HL*****/(NAME OF NANDROID)/wimax.img

Substitute the name of your nandroid back up file for: NAME OF NANDROID.

That shows whether your RSA keys are currently backed up, by RA's recovery only at this time.
[EVO 4G Q&A, Help & Troubleshooting] cc2278:
I used this step to back up my rsa. I'm already rooted

If You have already rooted your phone the process is much easier:

1. Connect your phone using the USB cable. Make sure you select USB Charging mode on the screen.

2. Open a command prompt window from your PC and navigate to where you extracted adb_shell.zip to. In this example, we have extracted it to c:\adb_shell

3. type the following into the command line:

Code:

adb shellThat will immediately drop you to a root command on your phone. You will see the # indicating you are at a root command prompt.

4. Proceed with the sed command below:

Code:

sed -n '/BEGIN CERTIFICATE/,$p' /dev/mtd/mtd0 > /sdcard/rsa_OEM.keyNOW PAY ATTENTION. Once the command completes succesfully, you will not get any reports of it completing. It will simply drop back to the # prompt.

If you get an error that states something similar to "sed command not found" then you do not have busybox running on your phone. That's ok, its not the end of the world. Keep reading, were going to modify the command a little.

when it was done I got # and is good, but when I check my phone sd card the

rsa_OEM.key is show 0 kb there is nothing in it why. It should be something like 4575 KB.

Please backup your WHOLE wimax partiton.

Not only are there RSA keys, but you have a user name, password and MAC address needed for Wimax to work. The best way is to backup the whole partition.

Your wimax partition will be about 12MB in size and is a binary BLOB. The first few bytes should be "HTC-WiMAX-SQN1130"

The command to make a backup is:

cat < /dev/mtd/mtd0 > /sdcard/wimax.img

Do this from an "adb shell" or a terminal emulator on your phone. You will have copied the data from your NAND (flash memory) partition #0 into a file on your sdcard named "wimax.img". Back that file up on your PC or elsewhere for good measure.

Note that a cat < /sdcard/wimax.img > /dev/mtd/mtd0 will not restore the wimax partition. The NAND needs to be erased and written using a special program like mtd tools designed for flash memory. Amon-ra will do this for you.

When do you have to worry about losing the WiMax/RSA Key?

noob question --

I have rooted my phone using the beta unrevoked a couple of days ago and I have backed up wimax/RSA use the SED/CAT command in this post and have done a bunch of nandroid backups using the clockwork that came with beta unrevoked (I think version 3.0.0.0 or 3.0.0.2. I have flashed the Fresh rom as well as CM rom a couple of times. Currently I have Fresh loaded and my 4G stuff works fine.

So, the question is, if I'm rooted and have done some ROM work, and my 4g stuff continues to work, do I still need to worry about losing the RSA Key or the WiMax partition or is it that once you are rooted and things are stable that you stay stable... I have done a lot of reading and I thought I read somewhere that once you have done some rom work and the rsa key doesn't disapper that it won't magically disappear if I keep flashing different roms..

Short of a proven restore procedure from the OP or someone else, you are better off making a backup using Clockwork 2.6.0.1, 3.x, or RA. Their backup stores the WiMax partition as an .img file. With it, you can just flash back using any number of procedures to flash an image file.
