I borked 4G - how do I fix it?

[JeffKay]

First, yes I did Google and search these forums.

It seems after flashing the newest WiMax radio, My 4G will not connect. The radio turns on, it sees the network is there, tries to connect and keeps trying. I tried flashing the older radio, no dice either.

I read somewhere that there are 4G security keys in the radio firmware, and when you lose them you're hosed.

PS.. I did ##33284# and checked WiMax Engineering.. It keeps looping at "Authorization"

Any suggestions?
Thanks

it fixed it for me..

Q: My 4g Doesnt work
A: Was it broken prior to the s-off, what steps did you take. Are you running AOSP ROM or Another kernel?, Did you try a different rom? What version is your phone? Do you have SwitchPro Widget installed? (uninstall it), Did you try to run unrevoked3 prior to this? After flashing the radios and stock kernel based rom did you do a data and prl update? Does the mac behind your battery match whats in about phone (4g has to be on to see mac) Also try the tree.xml fix posted

adb shell
ls /data/misc/wimax/

look for a file with your macaddress ending in .tree.xml. you want to move that to another location so it gets regenerated. (the following command basically renames it.)

mv /data/misc/wimax/(Your-mac-address).tree.xml /data/misc/wimax/(Your-mac-address).tree.xml.old

4. Start 4G may not connect
5. Do a prl/profile update
6. Power off the phone and power it back on. Try it
7. PRL/Profile. Try it
Q: 4G is still broke.
A: Check your RSA keys

adb shell
cat /dev/mtd/mtd0 | grep RSA

returned output show appear as this:
# cat /dev/mtd/mtd0 | busybox grep RSA
cat mtd0 | busybox grep RSA
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-----
#

It should look just like the above
the important lines are BEGIN RSA PRIVATE KEY and END RSA PRIVATE KEY.
If you have those two lines, your keys are still likely to be intact.
If those two lines are missing, your keys are likely missing.

/dev/mtd/mtd0 is where the wimax image is stored.

Ok.. thanks...

My keys are gone.

The last line after I run # cat /dev/mtd/mtd0 | busybox grep RSA

is "RSA replies".

Now what?
Thanks in advance

just this fixed it for me..

there is an instruction on restoring your RSA keys and I think you have found them. But your first order of business, once you are running is to get on ANON_RA recovery and do a NANDROID backup!!!

I totally agree! But.. It did not work. My MAC address of the WiMAx adapter got foul.. and I could not recover the keys for anything.

I did fix the mac address... but it still does not work.

If another guide exists.. please let me know.. thanks!

If you never made a backup of your WIMAX and lost your RSA keys, there is no way to get them back. Sorry.

[lkillen]

and what is borked?

Can sprint re-assign them?
