[EVO 4G Q&A, Help & Troubleshooting] debugguy:
Excellent information kf2mq so I think we can say, flashing radios is NOT the issue, it is (see post 26), albeit if you follow (post 25), you should have no issues, or if you do, you have a solid recovery.

kf2mq this would explain why some folks have no issue at all flashing the radios, you/me others, but yet some "appeared" to have issues, but I believe just like you say here, the issue was already there PRIOR to flashing the radios. It is still a hypothesis on my part but from what you are saying here and others have said, my bet is the early version of unrevoked was the culprit and any other "process" that does "anything" with the keys as part of flashing and does not "possibly" restore them. The variations of this could be many, so when all is said and done, if you take precautionary steps (1) backups, (2) understand what you are doing, most should not run into any problems and if they do, they will be able to recover.

I like many here jumped in feet first far too many times, call it lessons learned.

Thanks for the insight, I appreciate it.
[EVO 4G Q&A, Help & Troubleshooting] Crotchety:
I think your warning pretty much applies to noobs looking to do anything outside of warranty with their phone, including rooting and flashing ROMs. I've seen many people on here run into problems doing all of that, so I don't think any less caution should be used than for flashing radios. That said, I have also flashed all the radio updates on my EVO since release including the current one from Caulkin and have never even had a hint of a problem. When I'm in a 4G zone I get the same connection quality and speeds I've always gotten since before rooting.
[EVO 4G Q&A, Help & Troubleshooting] debugguy:
Well said Crotchety another case for flashing radios "in general" is not the problem here. I think you are right on point with everything you said. Moral of the story is, know what you are doing before you do it, smiling...thx
[EVO 4G Q&A, Help & Troubleshooting] mmegalodon:
Guess ill throw this out there, I lost my 4G / RSA Certs after flashing the WiMax Radio twice. Have seen at least two other people saying the same thing on these boards. Had a bad night flashing a ROM / Radios, issues wiping and that's how it happened to me. Never had issues flashing Radios before but it was clearly my own fault. I don't think flashing Radios should be avoided necessarily, but I do agree its probably good to at least warn of the "dangers." Not that we all don't know that **** can happen when messing with the phone. Seems like a small amount of issues compared to people successfully updating their Radios. But something to keep in mind I suppose.

[EVO 4G Q&A, Help & Troubleshooting] debugguy:
Excellent information conqu1stador

How did you recover, did you have a backup (wimax.img)?

Interesting, flashing twice, another variation that can cause the issue, hmm.
[EVO 4G Q&A, Help & Troubleshooting] mmegalodon:
Couldn't fix it, didn't have that backup unfortunately. But, fortunately(?) my phone was having other issues and was replaced by Sprint. So I'm good now. :D

That backup is what's important, without that (from what I've heard - yet to hear otherwise) once you lose those RSA Certs your **** outta luck.

As I said, didn't have any issues with flashing the radios before that night.

Obviously making people aware of something like this is a good thing, but most people don't seem to run into issues.* Important thing would be to have that backup!

*And I haven't looked too much into that Unrevoked issue that people seem to have run into with this problem, so I can't really comment on that. Not sure if somewhere along the way with that it happens or if something isn't properly done ... don't want to say anymore because I really don't know. :)
[EVO 4G Q&A, Help & Troubleshooting] dwertz:
I was trying to find it and as I was reading some people that did the simpleroot and are not having an issue. Maybe someone can confirm this. It would be the simpleroot(unrevoked 1) for 1.47 about May timeframe. I think my point with unrevoked 1 is mute. I see other people that have used it (not sure if they are talking Unrevoked or Unrevoked 2)and do not have the issue. It looks like several things are causing it, maybe flashing a bad wimax or radio file. idk
[EVO 4G Q&A, Help & Troubleshooting] bigbiff:
Just wanted to chime in. I lost my RSA certs by flashing wimax fw twice. Not sure why my certs weren't backed up, I think maybe I used two different fw image releases? Not sure...

Anyways I had an issue again with my replacement phone. I used amon ra 1.8 to restore wimax.img and restored 4g again. I have no idea what killed 4g this time! Never updated wimax, just pri and radio. Like was said above, I heard that the way the image was flashed in the updated radio was the culrprit for losing the certs in some of the wimax releases including the unrevoked release a while back. Unrevoked later removed the update from circulation after reports of messed up 4g. Apparently I guess if you use the wrong function to update the wimax image, hboot wont store the RSA certs in memory before writing the wimax image, therefore you lose them forever. If you use the right function, hboot will write the keys properly after writing the wimax image.

My second problem was the radio would turn on, scan then turn off.

Please correct my assumptions at will. :D

Use command prompt and cd into tools.
[EVO 4G Q&A, Help & Troubleshooting] CTH-EVO:
If you download the SDK & NDK

You simply choose a place to extract them (C:\ is a good choice for Windows users).

You'll end up with a android_SDK_xxx (where xxx = version number) folder:

C:\android_SDK_xxx

Within that folder will be a tools folder.

THIS is the folder talked about, that has the adk commands.

IMPORTANT:

Read the documentation that comes with the SDK & NDK. Important information

is there, that you MUST know, in order to use the adk commands, and SDK/NDK.

[EVO 4G Q&A, Help & Troubleshooting] Gadget Man 007:
Like I said, you have to use command prompt. There is no GUI (graphic user interface).

In command prompt type

cd C:\android-sdk-xxxversionnumberxxx *press enter*

cd tools\ *press enter*

Now type the ADB commands you want to do.
[EVO 4G Q&A, Help & Troubleshooting] debugguy:
Gadget Man 007 , if you are running Windows 7 x64 like me for example and you installed the SDK in the default location, you do this, (1) connect via USB your phone to your computer (select "charge only"), (2) start windows explorer, navigate to c:\android-sdk-windows\tools, highlight the tools folder and hit shift+right mouse click, from the menu, select "open windows command window here".

Now you have this: c:\android-sdk-windows\tools>

now type this in the command prompt: c:\android-sdk-windows\tools>adb shell

# <- you should see this, to the left a # prompt, if you don't type su then press enter

** Now start your 4G (the 4G radio) on your phone, then type the following:

# grep RSA /dev/mtd/mtd0

it should return something like this:

RSA-REQUEST

RSA-REPLY

RSA-REJECT

RSA-ACK

RSA-1024

RSA-REQUEST

RSA-REPLY

RSA-REJECT

RSA-ACK

RSA-1024

RSA

ReRSA

RSA requests

RSA replies

-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----

For most of us, these last two lines are an indicator our RSA Private Keys are OK.

While still at the command prompt, with your 4G radio still running type this:

# tail -f /data/wimax/log/*.log

then press enter, start and stop your 4G radio, you can watch your radio work.

havent read too much of the posts here but i have read threw the entire radio topic and have come to the conclusion (as said in a post) if its not broken dont fix it.... after all my reading and research i felt comfortable flashing the pri, prl, and NV....everything else seemed to be nothing but problems.....so if this is well known info here im sorry but im glad to see this stickied...
[EVO 4G Q&A, Help & Troubleshooting] debugguy:

[EVO 4G Q&A, Help & Troubleshooting] merkindude:
thanks Gadget Man 007 and debugguy. I finally got it to run. I got the last two lines "-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----" and i also got my values matched (OK,Pass,Match,<correctMAC>,OK). so i am assuming that i am ok. I have flashed my radio, wimax and pri. I believe i even flashed my radio and wimax twice in accident. So now i ask, what should i do... do just do a nand back up of the rom via clockwork mod or ra recovery?
[EVO 4G Q&A, Help & Troubleshooting] debugguy:
merkindude yes perform a nandroid backup now, BUT remember, ONLY RMON RA backs up the RSA keys in the wimax.img, ClockWorkMOD does NOT backup the RSA Keys and/or wimax.img. So if you are not using ARMON RA, find it and flash it, then perform your nandroid backup.

Also, don't stop there, use Astro file manager or another file manager and place a copy of the nandroid backup on your laptop/desktop.

force your CPU to lower rate can reduce Power Consumption , e.g. 400MHZ is ok

turn off google sync and background sync , turn off wifi when not used

kill apps not in use

dim your screen

use the latest kernel, then ur android will last till battery is empty

[Fascinate General] yuhang:
If I root my samsung fascinate... am I able to continuously update to the newer version of Android? Or does it require additional assistance from the good people of XDA? thank you in advance
[Fascinate General] stayqued:
Most likely will either not accept update or will lose root upon update.

That's what happened last time.
[Fascinate General] yuhang:
so if new updates from google android comes out, even if I root the phone i can't just go and download the new version?
[Fascinate General] ivorycruncher:
If all you do is install apparently that require root access, you should be fine. You'll just lose root access, and have to re-root afterward. If, however, you remove factory apps like Bing, or do any other OS modifications like the lag fix, there's a much bigger chance that the official updates will either fail, or cause problems. In that case, you either need to revert to stock before updating, or rely on xda developers to roll out customized versions of the updates that you can apply with your modifications in place.
[Fascinate General] yuhang:
So, the "official update" from say verizon will not work as well if I remove all the bloat ware... however, a rooted phone will be able to take in updates from Google ANdroid...like 2.3 or 3.3 etc... with no issues?

Perhaps to clarify a little further, I wish to purchase the Fascinate and root it. In the future, as new Android versions come out, I would rather take the official Android versions by Google instead of the updates by Verizon. Much like the Tmobile G1, is this possible once rooted?

I understand this is rather a long post so I appreciate all the help. Thank you.
[Fascinate General] ivorycruncher:
There are no Google updates vs. OEM updates released through the carriers. All updates are carrier-released, regardless of the source (OEM OR Google), and are model-specific, largely due to OEM OS customizations and differing hardware. The only phones that get pure Google updates OTA (somebody correct me if I'm wrong) are the ones that are released with a 100% stock Android ROM from the factory.

The only OTA updates you will get for the Fascinate will be from Verizon, and will require a stock ROM, and most likely will need all original apps in place. If you want the pure Google updates, you will need to install a custom ROM with those updates.
[Fascinate General] ivorycruncher:
Oh, and just to clarify, if you install a custom ROM that gives you pure stock Android, you will have to rely on the developer of that ROM to release updated versions that include the latest updates from Google. There are no OTA updates for custom ROMs, as they are not supported by Google, your carrier, or the phone manufacturer.
[Fascinate General] mexiken:
The only phone that truly gets untouched virgin updates would be the Nexus One, and even then the drivers are added by HTC.

The Moto Droid I guess would be the next one to also, but its been so long since I used a purely stock version that I remember if Moto adds apps at Verizon's request.

All carriers request what features/bloatware to install/not install. They send said requests to OEM, which turns around and incorporates the requests, and adds their custom branding/widgets/etc to send back to the carrier for testing. The carrier then has its own internal testing to verify requests and make sure no new prevalent bugs pop up. No one at Verizon (or any carrier really) actually does any coding of any kind.

What the OEM's receive from Google may be what you consider a "pure ROM" with "hooks" built in so that the various OEM's can add their custom homescreen, bloatware, brand specific widgets, etc. But, with the source being released most likely what happens is that this job now falls upon the OEM's themselves to write in their own "hooks", as Google just pumps out strictly OS generic builds into the ASOP.

In which case, either Sammy or Moto or whoever pulls that and fixes whatever issues, or they have internal builds going (which is more likely) that they tinker with to fix issues.

I believe Moto does this as evidenced by the lettering of the builds. Seems like they go through builds nightly when they are working on an update for a phone. I wouldn't be surprised if Sammy was the same way.

Sorry to make this post so long. Hope this helps.
[Fascinate General] yuhang:
So, a phone has to be "rooted" to allow full control over the phone. In this mode, I am allowed to make changes to the phone such as downloading ROMS that imitates the basic stock version of say the Froyo 2.2 In the future if a new version arrives, I can expect the upgrade from either Verizon (which I will have to unroot) or hope that the good people of XDA find ways to put new version of the Android in to my already rooted phone.

So, if I have a android phone and if the hardware is popular enough, people will continue finding ways to put new Android versions on the rooted phones through ROM. I hope I am understanding this matter correctly...

If that is the case, I now will go search in the threads for a way to root the Fascinate and find a ROM that lets me have the stock version of Android. I am very satisfied with the great people on this thread and I am very thankful for your responses and patience. Thank you very much.
[Fascinate General] mexiken:
Yes. You've got it down for the most part. If you root there are methods to unroot that will allow you to download the ota update. But with any luck the devs will get the froyo build long before it gets officially released and will be properly rooted by then.
