[Solved] CM7: downgrade from RC1v2 to RC0 due to wifi probs

With CM7 RC1v2 I get serious problems with wifi and minor problems with GPS. Plus Gmaps freezes, even with Setvls tuned. So I tried to revert to RC0 but that gives me bootloops.
My settings: German Froyo base.
My steps: w and w/o cache/dalvik clear. Replaced wifi driver with the one from RC0. Did't work.
I'm on a trip through europe, 5000 km from home. So I can't do big downloads.
Any idea how to solve the problem?
How to downgrade, how to fix wifi/gps?
Thx

honestly, it's urgent. sorry for bumping.

U need to redo every thing to go
Back to rc0 ie flash sbf n all that...
Try to clear cache n davlik cache...
that's all I know.. .
Swyped from my MB525 using XDA Premium App

I found a solution for wifi problem by myself w/o downgrade:
Delete the file /data/misc/wifi/wpa_supplicant.conf and reboot.
Make a backup if you want to recover passwords of your wifi networks. Didn't manage to include old pw in new file but I'm happy.

What kind of problems ins wifi u have?
I'm asking cause i got some problems too, in my case the wifis spots was not showing when wifi turned on, just showing the ones that was saved when i used.
Deleting them solved but temporarily only, cause sometimes i need to put forget in some saved spots that have a big password, then later need to rewrite all the passwords, and its annoying.

Had your problem exactly. Never tried deleting old ones.

strange thins some users (me 2) had problems with the wifi from rc0 maybe its a phone thing or some hardware differences

In my case wifi always disconnects. I only can solve this problem if i reconnect.
But it always happens again.
Should i try the same thing than measel ?

i don't know. but since it's easier then reinstall...maybe it's worth a try. i just found out by trial and error. just be sure to make a backup.

so i deleted this file and it seems to work out for me. Didn't have this problem since then

sorry i was wrong, my problem is still there

WiFi calling doesn't work on any ROM

I can't figure this out to save my life.
WiFi calling simply doesn't work. When I try to open the app on any ROM I get an immediate FC.
I've tried the wifi calling patches. I've tried fresh ROM installs. I've tried all the kernels. I've tried reinstalling the WiFi calling apk. (Though I don't think I properly got rid of the old one first, so that might be it)
The patches REALLY don't work. When I flash those the phone boot loops forever.
It's not that the wifi calling app opens then simply doesn't work right. It won't even open. It certainly acts like a problem with the app itself, rather than than the phone's ability to properly utilize the app...but I'm just guessing.
Any thoughts?
I'm very open to proper steps to completely remove wifi calling so I can do a proper reinstall instead of just trying to install over the existing version, which is what I think I've done.
I did recently upgrade to the updated firmware, in case that's a known cause.
I can't imaging the radio has much to do with it since wifi works fine in general, just not for calling.
The goal is to get it working right on CM7 for right now.
And if this is like a REALLY noob problem that I'm missing an insanely obvious answer on.....then you get double thanks for dealing with me.

Well first off do you have the tmobile cid and the right mid? If you don't have either it won't show on first boot for tmobile sensation

I have SuperCID 11111111
Does that louse it up?
I have no idea what my Mid is

Yeah that my, as for mid look for a thread called or similar to guide to fix wifi calling

Okay...still working on this.
I put my CID back to a stock T Mobile one.
My MID is PM581000
So that's all normal. I can see the app icon just fine. It just doesn't run.
The force close error says com.android.kineto has stopped.
What could be making the process stop?

Bumping this to see if anyone has thoughts on this.

[Q] Wifi Error (but not your usual error)

ok, so weird issue for me.. and idk if anyone else is experiencing it cause it doesn't seem like it.. I'm getting wifi error (and before anyone says anything about my router, it's already configured). It just won't turn on no matter what. I hit it, it says a grayed out "Turning On..." and then error again. No attempt or anything. I go into wifi settings and everything under Wi-Fi is grayed out, that's the network notification at&t wifi hot spot setting and wifi networks. I've been trying hard and absolutely no resolution. A google search only affords me more "fixes" for my router and that's not the issue. If i can get a referral somewhere else that doesn't talk about the router being the issue then i'd greatly appreciate it.

I've never heard of that error before so I don't know. Are you rooted? What version of Android are you running? What I'd do is backup all your apps, text messgs, contacts, etc., and do a factory reset and see if that fixes it. Worst case scenario you could flash a fresh new version of 2.3.5 via RSD Lite and you'd almost surely have the problem fixed, unless it's a hardware issue.

I actually started off on 2.3.5 with the issue, and then i started having problems with my ability to actually get past FB, so i had to do a the rsd fix where i force stock on there again. From that point since it still wasn't working I went and pushed ota which took forever and got onto blaze hoping/praying that it would finally work after that. ultimately nothing worked so I'm here now at the mercy of the forum hoping some guru might have something that I could try.

Wow brother, if you flashed the 2.3.5 fxz to it and still had the problem, i'm thinking there's a hardware issue.

yea, i figured. so i've already contacted motorola and since i'm still under warranty i can return it and they'll send me another one. them's the break, but i got 2 weeks before i even have to decide on that so its not something i'm rushing towards lol

Try going to adb shell
su
ifconfig tiwlan0 down
(toggle airplane on then off)
ifconfig tiwlan0 up
(toggle airplane on then off)
Maybe that will bring your adapter back up. Hope that helps.

hope this doesn't mean anything bad, but it says error no such device
i did adb shell in cmd prompt, it started up went [email protected] then i did su and it changed to [email protected] and i did what you said.. and it gave me that error

Had the same error problem a few ago using blaze v3 rom. After reboot, it was solved and I could connect to my wifi again.
Have no idea what caused the problem, as I didn't do anything out of the ordinary with the device since the update from blaze 2.5.
Sent from my MB865 using XDA

I am facing same issue on Droid 3. it does not work with Stock ROM, but works with CM9 or AOKP based rom.

wifi error afterusing motofast fast script 2.3.5

only once did i have problem with wifi on this phone and i never fixed it on 2.3 ...
after a lot of trial and error though, i got it fixed with upgrading to ics.
other than that, does your bluetooth do the same? because symptoms like these usually mean water damage. you might want to check the indicators, (if the a2 has any) --- if you broke your wifi by updating rom, this probably isnt the case.

I noticed that the description for the wlan interface is different in the build.prop between GB and ICS. So you might check your /system/build.prop.
Look for this towards the top of your build.prop
Code:
# wlan interface
wifi.interface = tiwlan0
softap.interface = tiap0
In GB wifi.interface = tiwlan0
In ICS wifi.interace = wlan0
So make sure the value is correct, if the value is wrong it will show your wifi "greyed out" in the settings. Anyway, it's something to try, and I hope that helps. If you change the value, make sure you reboot then check to see if it is fixed.

Since I don't know if anyone is still looking into this at all because I haven't seen many updates to this thread, I'm wondering if anyone has checked the kernal information. I was able to do some searching (btw I haven't sent in my atrix 2 in yet because of work) and I found that there was some issues in regards to the Kernal. I don't know if thats true or not but I would like to see someone test it out or try it out or what have you and see if they can shed some light on the situation because the situation is rather bleek, and i'd rather not have to send in a perfectly good phone that was working just fine before the flash, and still wouldn't work after reflashing the AT&T rom.

Intermittent Data/Cell -Exclamation Mark in Signal Indicator

This happens on every Lollipop ROM I have flashed, no problems on 4.4 ROMS. I do clean installs, do not restore anything from Tibackup. So basically what happens is I will randomly but very frequently lose all data and cell service. Like once every three minutes frequently. It only lasts about 5 seconds at a time. The signal bar triangle will have an exclamation mark in it (see attached example). I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option. I have read some threads about this exact same thing happening on Nexus 5 after Lollipop update but they are old and it seems to have been fixed with an update. Does anyone have any ideas about what is going on? I'm on TMO in the US and like I said, it ONLY happens on Lollipop ROMs it does not happen of Kitkat.
I read this as sort of an explanation as to why but nothing as to how to fix it. It is driving me insane.

I'm in the same boat, I cant make calls with hangouts or with Dialer or it will disconnect. I haven't seen a solution yet. I've tried every ROM I can, but it keeps crashing. drives me up a wall. I want to logcat it, but having issues while at work.

Only discussion about this I have seen is in the Nexus 5 forums, nothing in OPO

Any insight to this would be greatly appreciated.

You're not alone, I have this as well but I don't get the exclamation mark but instead the triangle appears completely empty, as if I have no signal at all.

anyone know a way to fix this awell? i flashed the new lolipop alpha modem and still same thing if not worse

The only time this has happened to me is when I toggle Wi-Fi. It for this every time, but have no data issues otherwise. Seems to be when switching between ip addresses. Are you possibly between towers or roaming on another network? May be the issue, but I can't say for sure. Running the lollipop rom exodus, no issues at all.
EDIT: also what baseband are you guys on? I thought I saw something similar and someone flashed a test baseband and it fixed whatever issue they were having. Link coming shortly.
EDIT 2: just now noticed the list above mine about the alpha modem and it not working for them. If anyone else needs to try however, link is http://forum.xda-developers.com/sho... work for some and not others.

Does anyone know if we can flash the CM11S modem on CM12?

Go to Settings -> More - > Mobile Networks. Make sure all the items are set correctly.

In OP "I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option."

Same issue here. Running SlimSaber using alpha radio.

Same problem on two OPOs here, both running Temasek CM12

Anyone found a solution yet?
I have the same issue on CM12, BlissPop and Validus ROMS.
Strangely I do NOT have the issue on Euphoria.
Think it happened after I flashed the Alpha L modem.
Tried flashing an older CM11S modem, but no luck...

Hi,
Sorry for the noob answer but anybody tried settings>mobile networks>preferred network type and set it to 3G? I flashed a new rom from stock CM and noticed that I was experiencing signal trouble, I checked my status and the signal detected is LTE so I changed my network to 3G and network signal improved. Downside is that you cant use LTE (but thats ok for me since here in our country, LTE signal is still kind of limited)

Zino same for me. Ever find a fix or a rom that doesn't do this?

OP here, it's strange that all of us have this issue, the same issue that came up on the Nexus 5 thread when L was first released but know one else seems to have any knowledge of it. I am almost certain it doesn't have to do with our carriers but rather something software related.

I'm also suffering from this issue, until now the only way I knew how to fix it was to wipe the cache in recovery which takes ages!

got the same problem :<

I have a similar issue. I use t mobile in the USA and LTE works, H+ works, but 3g shows signal and won't load anything. No idea how to fix it.

Issue with mobile data connection

Dear all,
I own a OP6 always updated through OTA. But I have a big problem: often, and without noticing it, the data connection is interrupted and the only way to reactivate it is turn off the connection from the menu, wait a minute, and reactivate the connection. It happens several times a day.
As you can imagine, it is a big problem because someone sends me emails or messages that I do not receive until I do the steps above. And I don't know when I'm connected and when I am not because everything seems okay.
Can you help me?
Thanks in advance.

Just out of curiosity, did you try downloading the latest full rom and flashing it? I was always having issues with severe battery drain if I updated by OTA. Downloading the rom from OP website and flashing fixed the issue. Could be something similar for you.
Be sure to do a backup first incase of any problems.

Not similar but this the only case. I learned it through 4 devices OTA updates always mess up something. Always do full clean install, i know it sucks to settup the phone again install backups.. etc.. but it gor good

I think i have the same problem but after every reboot. I get 4G icon, but there is no connectivity on chrome and other apps (although Spotify seems to work). Only after switching to 3G and back to 4G the data works...
I had the same problem on my OP3 in OOS, but not in Resurrection Remix... really weird. I may try Havoc OS to see.

No problems with mobile data here, but dame issues when on wifi. I did a factory reset yesterday and clean install, but sadly that didn't help.

I've just updated to OxygenOS 5.1.11 and the issue is still with me. How is it possible? It's a really annoying bug. Developers, where are you when we need you most?

Does anyone know what the best apn and network settings are for an unlocked Moto g5 plus on metro by TMobile

When I use OP6 on mobile data, cant use google or associated programs... Used a VPN program and problem is solved.
Updated: deleted all APN and insert manually APN for my network. Works just fine...for now.
