[Q]May day!!! 4G Problem after the current updates today

[Ky1e.YC]

Guys, having a serious problem here to connect 4g network. I m working at Dallas, TX, where 4g network is available. Here is what happened.

I flashed the latest radio updates, 2.15.00.09.01 (not combination version, just radio), then I used HBoot way to update PRI to 1.77_003. Then problem showed. when I tried to connect 4G, the status looping in "turning on...scanning(in 1,2 secs)...turning off...turning on....". I started to ask questions in here and central. Meanwhile, I downgrade to 1.34_003 since there is no solution. But, strangely, the same problem showed(i pretty sure that 4g works on the 1.34_003 before).

Tonight, I heard Fresh 3.3.0.1 out, so I flashed at the first time(wipe cache & Dalvik, no data wipe yet), also flashed flipz radio zip file to 1.77_003, problem is still on. On the other hand, someone from android central suggest to delete wimax.tree.xml, i did, still no fix.

At the last and now, I wipe everything, partition sdcard, flashed fresh 3.3.0.1, then downgrade to 1.34_003. When I tried to connect 4g, at the very first time, after half-min, the status shows "unable to start 4g", if i try to connect again, the status will be in the "turning on..." forever, i have to reboot to stop it, after reboot, the status of 4g network shows "failure". I did PRI "OTA" updates (##786# Way) to 1.40_003, same situation. Now, I m really afraid I broke something, and brick my 4g connection.

anyone can give some help here?

I flashed WiMax again this morning, suprisingly, 4g status finally starts with "turning on... --> Scanning ---> Connecting to Sprint ---> Scanning". Unfortunately, it still cannot connect successfully. I tried to delete tree.xml, still doesn't work.

Did you read the guides on xda about fixing broken 4g?

I don't know if this will help you, but updating to 1.77 broke my 4g (I am in the Mid-Cities). After trying the treexml fix, downgrading to 1.34, changing ROM's and everything else I could find or think of, I noticed that 4g worked occasionally. What I finally found was that it wasn't playing nice with SwitchPro widget - for some reason, if I turned on the 4g toggle it might connect, if I went into settings>wireless>4g at that point and checked "turn on 4G" it would loop. If I went back to SwitchPro and un-toggled it, I could turn it on in settings. Or vice versa - it made no sense. I deleted SwitchPro, reinstalled it and created a widget without the 4g toggle and have had clear sailing ever since.

First of all, thanks for sharing, man. Mine seems not work at all. I would like to try the way you described.

Even I uninstalled switch pro, still now working. still looking for some other reason. just check wimax version, there are a few error.

It definitely works, my friend did it and his 4G was back up and running in under an hour.

I encountered some weird question after change MAC. when i do check by wimax_mtd, it matches the MAC on my box, but when I delete that tree.xml file, restart 4g, the new xml file create is still wrong mac address.tree.xml.

Ask the question on that thread, I wouldn't know the first thing about fixing 4g. I haven't broke mine.

Can you show me how to downgrade to 1.34_003? I have 1.77_003 but it doesnt seem to work well. I'm losing battery like crazy...

Did you fix it? what rom are you running? There is a WiMax update that JerzyIROC gave me that might help... it's on Vaeleks website... I think someone linked it for you already tho... I had problems with my wifi tether, butafter i flashed that, 4g and wifi were fine..
