UPDATE 3-5-11: After loosing my wimax keys, I now have them back. Well.....not my original keys, but I now have 4G. This could be a possible fix for those that have lost theirs. I had the opportunity to get my dad's broken EVO before he sent it back to Sprint from claiming it on insurance. I rooted his phone using xda-developers - View Single Post - How to start over: Fully rooted stock 1.47.651.1 in one shot (no adb!). I then created a nandroid. From the nandroid I was able to steal his keys!!! I then downgraded my phone to match his phone after rooting, which was 1.47.651.1 by flashing xda-developers - View Single Post - [ROM] OTA 1.47.651.1 Rooted - De-odex'd version now up..... I took the broken EVO nandroid out of the HT05******* folder and put it in my HT05***** folder. Booted into recovery and did a restore. I was very excited to see that it was at least able to restore the broken EVO's nandroid. I then corrected my Wimax MAC address by xda-developers - View Single Post - [GUIDE] Bad WiMax MAC? Broken 4G after update? Fix HERE!. I now have 4G connectivity again! It might be possible to scan ebay for broken EVO's. Then do the above method to get the Wimax/RSA keys and put them on your phone. Yes, in my case, I may have 4G connectivity problems in the future since the broken EVO was mailed back to Sprint. BUT, if you find an EVO on ebay and do this method, you should be good because you would still have the broken EVO. Take this for what its worth. This was just my way of solving my lost Wimax/RSA keys. My EVO connected to 4G http://androidforums.com/evo-4g-all-things-root/261080-solved-missing-wimax-keys-3.html#post2384668 ========================================================================== so i have been running CM6 for a while now. i live in a 4g dead zone, but i have wifi at home. when i got out, usually the places have free wifi. some dont and i miss having 4g. but i look on the positive side that i am not on sense! after the cm6.1.2 wimax alpha release i became excited again as well as other CM'ers. i figured my keys were fine this entire time because i have rooted as instructed by toast. i recently updated my hboot and RMA. of course i did a nandroid before i did. i decide to load cm6.1.2 wimax alpha 2. i have tried 4g at home and still cant get it. ive tried in places in the dallas area that i know have 4g and i still cant connect. ie scanning, connecting, scanning...... guess its time to check my 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 # i did NOT see -----BEGIN RSA PRIVATE KEY----- -----END RSA PRIVATE KEY----- sed -n '/BEGIN CERTIFICATE/,$p' /dev/mtd/mtd0 > /sdcard/rsa_OEM.key rsa_OEM.key = 0k ok, where did i loose them? hmmmmmm. i have flashed and nandroid'd so many times since ive rooted i cant even count. when froyo came out, i dumped my all 2.1 nandroids. haha, bad bad mistake. i should have known to never delete backups of anything. i just downloaded/installed file scavenger v3.2 from download.com to see if i could recover my old nandroids. the good news is, it has found old nandroids from 9-3-10. bad news is, i have to pay $50 for a serial number for file scavenger before i can restore them. once i do that, i will have to flash each nandroid and check to see if keys are there. once, and if, i find the nandroid with the keys, how do i get em back onto cm6.1.2?
