[EVO 4G Q&A, Help & Troubleshooting] pabdaddy1995:
I was wondering if anyone can help me fix my 4g problem ( missing rsa keys according to Wimax key checker). I'm actually on the SOS 1.9.0.8 swag on release. And I even tried to restore my original Wimax .ing file (from original shipped Rom ,after rooting) using the latest version of clockworkmod. Any help is greatly appreciated.

Update:

I was able to fix my missing RSA key problem but it wasn't obvious (at least not to me). And I'm not even sure which of these steps actually fixed it. But know this it is now fixed. Anyway here is what I did.

1. I first attempted to just do an advanced restore of my original 3.70.651.1 rom and only restore the wimax keys. (DIDN'T Work)

2. I then attempted to restore the entire original rom 3.70.651.1 rom to see if the RSA keys would fix themselves (AGAIN DIDN'T work)

3. I then tried to create a wimax.img file using the manual approach (i extracted my public cert and rsa key and followed the instructions with my wimax mac address to create another wimax.img file.

4. In those directions they explain to erase your wimax keys in fastboot. I wasn't able to do this, so i moved on assuming this was because i had no keys to remove.

5. Once in recovery (clockworkmod 5.0.2.2.) I formatted the wimax partition.

6. I then did an advanced restore an only restored my wimax.img (the original version) not the manual version from #3.

7. Not expecting this to work I then flashed the latest all in one radios/wimax/prl etc.

8. I then did a fastboot restore of the original RSA keys as well using fastboot wimax /sdcard/wimax.img

The phone showed the android out of the box thingy (typical when you flash radios) and then rebooted. When it came up the 4g automatically attached with no problems.

I suspect this is because either the fastboot programming, wimax erase (before programming), or the reflashing of the radios again.

Hope this helps someone else.

If restoring your backup didn't restore your Wimax keys you might be SOL
[EVO 4G Q&A, Help & Troubleshooting] kz6fittycent:
Dude....help me out!

You're giving me some hope...

I am assuming that you used a sense rom to perform this restore or did you just restore 'a' rom with working 4g?

I was using CCM but switched to Amon-RA...far too late! I am aware of the advanced restore menu and I tried that method thinking it would work. However, I didn't follow your steps, so....

In any case, the more information you can provide, the more grateful I would be;)...

Thanks in advance,

Well, I'm going to give it a try....from my original sense rom...will let you know...

1. You should use search button, I've seen 4 topics about this already.

2. Just flash stock rom then go to sprint and tell then 4g doesn't work. They will fix or replace phone.
[EVO 4G Q&A, Help & Troubleshooting] kz6fittycent:
Boo

Dude,

I have spent the last month SEARCHING. "JUST FLASH THE STOCK ROM AND...." You don't think I would have already tried that?

In addition, I want to try to fix the problem myself. If someone has some NEW information (e.g. something that is from the year 2012 and NOT 2010) I want it. I want to use it.

Please, don't think that I don't love you or anything but sometimes you say the meanest things.
[EVO 4G Q&A, Help & Troubleshooting] AFschizoid:
kz6fittycent: First, awesome avatar lol, thundercats were amazing.

second: what recovery are you using?

EDIT: sorry, just noticed that you switched over to amon ra.

I'm not used to any other recovery than amon ra, tried clockworkmod and it borked all my CWM NAND backups, so i switched back over to amon ra. go into your CWM nand folder (oldest date) and tell me what all you have in there, including extensions. i'll try to help if i can.
[EVO 4G Q&A, Help & Troubleshooting] kz6fittycent:
Well...ahem

Uh, I finally gave up..sadly. I tried finding and restoring my original back-up from CWM. I flashed CWM again and went into advanced restore. Flashed the wimax again and tried updating everything (e.g. PRL, etc.). No luck.

I now have a refurb from Sprint. Guess what! It no likey the 4g either!! I have been on the horn with Sprint about this. I have been to the repair center, as well.

After spending about 2 hours trying everything they knew to do, I am getting ANOTHER EVO. HAHA!

In the meantime, I have been trying to figure out why this "new" EVO won't connect to 4G. My guess is that it was another model that lost it's RSA's at some point (its a HW version "2", my original was HW version 4).

OH, by the way. When I called HTC about the issue, they had NO idea what the problem was. I mentioned RSA keys and they weren't aware that they existed. Sprint technicians were ignorant, as well.

In any case, I am hoping that this new phone will work. If not, I think that I might upgrade to the Galaxy S II-EPIC 4g (jeeze that's a long name).

In any case, my new phone will get rooted as soon as I can confirm a connection to 4g.

P.S. Just some food for thought. I spoke with the Sprint technicians about the 4gLTE network and the EVO. He stated that there would be a wimax update to follow for all previous 4G (wimax) customers that would allow us to connect to the new network.

I thought that was interesting. I wonder if this is true or if he was mistaken. In any case, I reckon of they didn't know what RSA keys are, they may not know much else. UGH.

I am currently running Calkulin's amazing ROM on my phone and I am enjoying the heck out of it. My question is I have seen his updated ROM (2.9!) will be based on the Rogue Kernel 1.4...

Now, I have several questions....

What are the differences / improvements by going to developer kernels?

Are there battery life improvements? Because at the moment I am very DISPLEASED with my battery life (Calkulin's 2.8.1 ROM / EK02 Modem / Stock EL29 Kernel)

If someone can break down the relationships between ROMs and Kernels would also be very helpful. Sorry to be a noob but I am learning and beginning to explore with this excellent piece of hardware (E4GT) and I am just looking to get the best experience from this device and take advantage of some of the talent on this website. But can someone out there help me make sense of all of it?

Thanks all, this concludes my first post and hopefully many more to come~!!!

[Samsung Epic 4G Touch] GRBlitz:
I think I require some more basic knowledge and understanding of the relationship between kernels, ROMs, etc before I can begin to see the value to all the changes and updates the Rogue 1.4.1 kernel provides.

Aside from that, bottom line, is will the Rogue kernel or any kernel for that matter help me with the ridiculous battery draining I am getting from the aforementioned setup I have above?

Thanks again in advance ;)
[Samsung Epic 4G Touch] patrao_n:
if you have just flashed it may need more time to "settle" in. the only way to calibrate the battery I know of is to fully charge keeping the phone on the charger the whole time. then when done use until dead. don't plug it in until like 3-5% left. charge again. same process. if there is a rogue app causing wakelocks you can use betterbatterystats and also cpu spy to check what is doing it.btw my setup is el29 everything. I am stock rooted with rogue el29 stock kernel.
[Samsung Epic 4G Touch] tenazrael:
This is what you need to know about a ROM and Kernel.

A kernel is a layer of code that allows the OS and applications to interface with your phone's hardware. The degree in which you can access your phone's hardware features depends on the quality of code in the kernel.

A ROM is a like a customized version of the Android OS.

When you flash a custom ROM, that ROM typically includes a kernel and an OS.

Here is a great write up on lifehacker about ROM's.

h ttp://lifehacker.com/5596108/how-to-choose-the-right-android-rom-for-you

Here is another good one on kernels and partitions.

h ttp://androidforums.com/evo-4g-all-things-root/278898-android-partitions-kernels-explained.html

The information although it was written for other phones, should be pretty close to the same as it is for the ET4G.

So when you ask yourself... it is worth getting the latest version of Caulkin's Rom with 1.4.1 gunslinger kernel. Check out the GunSlinger kernel updates to see what improvements it will contain.

1.4.1 (Minor Update, "Gunslinger")

Kernel-

+Added support for Voodoo LOUDER

+Low mem killer value tweaks

So if you want to install the Voodoo Louder app, and you need low mem killer value tweaks... then by all means... install the latest Caulin's Rom when it comes out. Otherwise... wait until a later ROM has something you HAVE TO HAVE.

ps. I'll need to come back to my post when I have more than 8 to update the links. :D
[Samsung Epic 4G Touch] Mynaga:
Actually, doing a battery calibration according to viperboy(developer) consists of charging to 100% going into recovery deleting battery stats. then discharge all the way to 0 and phone shut down then doing a full charge back to 100% with phone on. should take a few cycles after that but it should be more than squared away

i am on calks 2.8.1 and i have never had better battery life 2-3 days no charge hours of screen on time.
[Optimus One, P500, V General] Curiousn00b:
How can I do this without a sd card... thanks in advance.
[Optimus One, P500, V General] tvall:
Flash the recovery image?

Root

Adb push a flash_image binary to /system/bin or xbin

adb push recovery.image to /cache or something

flash_image recovery /cache/recovery.img
[Optimus One, P500, V General] Curiousn00b:
I'm trying to flash the recovery without a SD card, because my phone can't mount a SD card anymore. So I'm using the recovery here http://www.lg-phones.org/lg-optimus-v-custom-recovery.html and Flash_image to flash it, but I need ADB codes to do so. I'm not very good with ADB, so I need the ones without the flash_image recovery /sdcard/ recovery-thunderc-v-1.2.0-GNM.img /sdcard/ part. :/
[Optimus One, P500, V General] developer++:
It the same thing as tvall has mentioned but I will make it more easy for you.

As mentioned in the link that you have provided, just do this instead:

A) Type in 'adb remount'

B) Copy recovery-thunderc-v-1.2.0-GNM.img to platform-tools directory where android SDK is installed.

C) Do a 'adb push recovery-thunderc-v-1.2.0-GNM.img /system/xbin'

[Now the recovery image is inside your phones memory @/system/xbin location]

Following are the existing steps from the link: Modified step is made bold.

1) mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system

2) cat /sdcard/flash_image > /system/bin/flash_image

3) chmod 755 /system/bin/flash_image

4) mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak

5) mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system

6) flash_image recovery /system/xbin/recovery-thunderc-v-1.2.0-GNM.img

7) reboot recover
[Optimus One, P500, V General] Curiousn00b:
Thanks alot guys, I really appreciate it, but I get stuck at

Bump...
[Optimus One, P500, V General] developer++:
I have made inline comments. Just take note of it.

Here the 'recovery-thunderc-v-1.2.0-GNM.img' file should be present inside the C:\android-sdk\platform-tools directory. Also check if the spelling is correct.

This error came because there is no file called 'install-recovery.sh' inside /system/etc. This is fine since you are anyways not going to use that file.

This part I am not that clear but it might be that the recovery 'recovery-thunderc-v-1.2.0-GNM.img' is corrupt or may be 'flash_image' is corrupt. You can also check for the amount of free memory by typing in 'df' and 'free' respectively. df would give you phone memory stats and free would give you RAM stats. Verify if anything is too low.

For the last permission denied error do a 'ls -l' at /system/xbin and check for the permissions.

I will look around to see if I can get some clues till then, lets wait for someone who can help you better.

[ADVICE: Since you are playing around with system binaries make sure you take a backup of /system/bin atleast.]
[Optimus One, P500, V General] Curiousn00b:
I tried again about 8 hours ago. I got through everything with no error, but when I got to recovery, it was still the old one. I'll try again once I get home.
[Optimus One, P500, V General] Arjen:
Other option (if your phone is rooted)

Install RomManager and install CWM or alternative.

If you're not rooted you need to do that first.

After that you can flash any recovery you want and you don't need to mess with adb ;)
[Optimus One, P500, V General] Dan_Jacques:
You can try to flash a recovery via LGMDP. I've flashed CWM 4.0 by this way.

You can share the solution and provide a link so that in the future if someone has the same problem he can visit this thread and get things sorted out.

[Optimus One, P500, V General] Curiousn00b:
Can someone with a sd card, and adb, test this out? I don't want to test it out, cause without a sd card mounter, if it doesn't work, I'm screwed. If it doesn't work, I'm sure you have a nandroid on your sd card, hopefully. Please and thank you.

Perhaps the build.prop could provide more info.

If you aren't sure how to find it, download a file manager like astro. Navigate to the root folder. (press up twice if using astro)

Open the system folder and then long press the file that says "build" and open as text.

If you want to use adb you can type

adb pull /system/build.prop
