[Solved] CM7: downgrade from RC1v2 to RC0 due to wifi probs - Defy Android Development

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

[Q] Help with G Tablet!

I have three tablets. Not that I owe.. one is mine, another is my sister's, and last one is my cousin's. All tablets are on VEGA-n beta 5.1. My sister's tablet is doing some unexpected things. For starters whenever it is put to sleep it shuts down instead(not right away but after a min or two it shuts down). Second, both mine and hers are on the same network, but when hers gets 10 or more feet away from the wifi source it drops connection while mine still gets excellent connection. Third while on the same network, on hers only certain apps can access the internet while others cannot. Market was working earlier(downloaded Ti backup after reflash) but her Internet Explorer was not working. Now internet explorer works but market does not, even other internet explorers other than the stock one are unable to connect online. Lastly her accelerometer stopped working/was stuck. I reflashed and wiped all data, but nothing. Its still broken.
Should I return it? I have tried all the solutions that fixed some of these problems for me but they don't seem to work on hers. Any help please?!
Wow, its great to see that you all kept the G Tablet in the family.
1. Its an issue many of us have. We feel its software related since it started to occur after flashing the Vegan Rom.
2. Could be a hardware issue for your sister's device. Back it up, wipe it and try it on the fresh install and see how it reacts. If it works fine, then its probably something software related. If it still drops, then its more likely hardware. Return it.
3. Again, faulty installation of the Rom. Back it up, wipe it, and try installing it again. Also you may want to try TNT to see if its Vegan 5.1 related (btw, it doesnt use internet explorer)
4. I would return it if these issues persist.
Hope this helps. Anyone with other advice please chime in.
Thanks,
Scott
For the powering off issue, it sounds like the button might be sticking, on mine it forces the tab off if i hold it down for even a few seconds.
Also by internet explorer, i assume you mean the android browser?
Also is your cousins tab experiencing any of the same problems?
Mine and my cousin's are alright. Only problem I've had is flash crashing occasionally and rebooting. I might try flashing TnT lite on hers and see if there's a difference.
I have to head to work will update once I work on hers more. And thanks for replying..

I have been running vegaN Beta5.1 for a while now. Used to have similar issues with power and such. I flashed Clemson 10.9.3 kernel, it is now up to 10.9.8 and the power issues went away. It also has the lag fix, and some other nice fixes. It installs just like any other rom.

[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.

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.

MOKEE 4.4.2 Network Issue - GT-P3100

Okay so i have 4.4.2 in my gt-p3100 and am facing continuous network loss.
One second its there and the other second it says no service.
Then it identifies my cell network but shows this -
No Service- TATA DOCOMO
(Tata docomo is my network provider)
This happens usually when i am about to make a call or message or about to recieve a call or message.
The incoming call gets displayed for a split second and then bam..!
The network goes away.
And then again it shows no service and the cycle continues.
Toggling the airplane mode on and off sometimes helps, but mostly i cant get it even after several reboots or sim changes and everything.
I am really annoyed now.
This started only 5-6 days ago.
I completely reformatted this tab and had a fresh install but still it continues.
I have a custom messaging app called 8sms and xposed framework installed although i use just X-Privacy.
Besides i read that moto G users in my region are facing the same issue in their current KitKat version.
Just for reference : https://forums.motorola.com/posts/027c60e48f
Any help is urgently needed, thanks.
Bump...???
I hope this helps.
Clean install ROM. do not restore backup apps first. first log-in through your google account and restore all..
I experience same problem with other roms also slimkat, sensonic, dhollmen. what i did is restore my contacts and apn setting from my google account not from a backup. i hope this helps.
Well i had just cleaned and installed but what i did was let google restore the contacts and apn.
Then i manually restored some apks via app backup and restore.
And then i used Titanium Backup to restore the data in all of them.
Is this the wrong way.?
Thanks btw.
@gangpe well i changed the APN as u said.
But i was playing GTA San Andreas.
And a call came and it rang for a split second and then same..the network goes away.
But it came back automatically.
Still the issue is not solved coz it happens randomly .
Is the apn still there, or did it disappear? I ran into an issue once where the apn did not save for some reason...
Sent from my SAMSUNG-SGH-I747 using Tapatalk
Well its still there...
I chose the same name for it too, would that conflict.?
Also randomly it happens when sending/recieving a message too.
I click on send and suddenly it says no service and then the message cannot be sent even after 2-3 reboots. :-/
Bump..
Any one know any solution..?
Its starting to get on my nerves.
Random no service msgs.
And wont get stable unless 2-3 reboots..:-/ :-/
Not sure what to tell you. A few days ago, I had a few weird issues (could not install xposed framework, quick settings panel would not work), so I ended up wiping cache, data, system, and dalvik. After wiping, I re-installed the ROM, and I have been good since.
In my case, there was probably an old setting I had that was causing issues. If you haven't tried wiping those four options, then I would suggest you try wiping/reinstalling.
If you have tried that, not really sure what to say. Sounds like you might need to head back to stock for a while until a later release resolves the issue.
Mmmm...the thing u are telling is a case of wrong dirty flash of a rom, i mean u must have flashed a previous version rom without wiping over other rom version.
I have faced this too..but the thing i was facing seems to have gone now on current latest release.
Dont know but i did not fixed permissions from TWRP this time after OTA and now the issue hasnt surfaced since 24 hours.
Maybe i'l wait some more and check and report back here.
Thanks anyways.
Now i m gonna pull my hairs out..!!!!
Wtf is this sorcery.. I was watching a vid on MX player and again the no network issue started happening as soon as a call came....!
This MX player is the culprit i think..usually while watching vids this happens...
Same issue for me on p5100, it happens both on Dhollmen and Mokee.
I don't have MX player installed.
Often happens when watching videos, but I'm not sure if it happens ONLY WHEN watching videos.
However, no further way out than rebooting.
Sent from my GT-P5100 using xda app-developers app
Well i am facing this randomly..but usually while mx player is on.
I cant seem to find any solution to this.
In rare cases i need 2-3 reboots to fix this.
M soo very disappointed guys.
Have not a single site as great as xda and not many people are even looking at our problem.
I generalized the problem to most full screen apps.
And it happens usually while pausing the app and flicking down the status bar and doing some multitasking from there or pressing the home button.
Anyone....???
Or should i just try Omni Rom.?
Maybe Mokee has this bug..?
If you try Omni Rom, I really appreciate if you let me known the results in any case, since I have no free time and currently I cannot flash this rom
Okay mate, i'l flash that in about a week as my exams are going on.
Omni has just this battery drain issue.
It seems no one knows about the problem we are facing on mokee.
@loboz well i flashed omni and its feature packed..
No issues till now, a little different from mokee and you'l be glad you did as mokee's OTA are dead too..
Satisfied with omni..

[Q] MT7-L09 : Help needed, After encryption GPS not working

Hi guys,
I need help. Once I encrypted my phone. Location service/GPS is not working on my phone.
Before encryption. There is the location icon always comes up when I access something like Google Maps. even tried installing GPS toolbox. Able to see the satellites and all.
But after encryption, the location icon does not come up. But somehow in High Accuracy mode, it does get somewhere of an approximation of my location.(from network and Wifi).(This does not go well when you are navigating around)
Have you guys encountered this. I have even tried flashing the new L09 Rom and it is still the same.
Also searched around the forums (Looks like the old Samsung phones had this issue where after encryption the GPS would not work). But the post is way back in 2011. And they din follow up on the posts on how it was fixed.
I have factory reset my phone a number of times, flash new rom(the one shared on this forum)
Also played with the settings nothing happens. I still cannot get GPS to work after encryption.
Also another thing I notice is that during the encryption a strange error came up and say that Settings have stopped working. I do not know whether there is a coincidence or not and whether it has anything to do with this GPS problems..
Any help is welcomed. as having a phone with no GPS is really driving me up the wall.

Really sorry for late response - but you can fix this problem using attached file - this is apk from China version of Mate7 make you be able to give (or revoke) access to system data storages (including GPS) to applications.
I had the same problem as you - and using this apk i've fixed it successfully.
it doesn't work for me - can anybody sent printsceen of settings of this app?
Thanks
@nchee + @mireczeque
Have you BOTH re-flashed the stock rom by using the official HUAWEI procedure (i.e. three buttons pressed togheter and ROM saved on DLOAD folder)? If so, do you have ALSO applied a WIPE DATA FACTORY RESET plus a WIPE CACHE PARTITION?
I had some problems with APPS crashing when I tried restoring my HAM with B130. I WIPED everithing and THEN re-flashed fresh B130 from DLOAD sdcard procedure, and everithing worked perfectly. I hope this help.

Internet is very slower, pls help

Hi guys, i have really annoying internet problems. For some reason a week ago my wi fi connection got very bad, and its just on my phone. On other devices in house wifi is fine, but in my case there`s a problem. Maybe problem is new update for nougat, i dont know, maybe something else. At first i tried with deleting cache memory and deleting some apps, but that didnt work. Then i checked other devices in my house and they arent lagging.
I hope u will help me, because i bought this phone a month ago and im losing my faith in him.
Problably a simple software issue, like a wrong dns, delete(forget) the wifi from your phone and reconect to it without any manual settings.

I had slow WiFi too, in my case somehow it's caused by the Bluetooth. Whenever it's on, my WiFi slows down from 30 mbps to 1
Have encountered the same problem and only thing I tested, is disabling the Bluetooth or going to Direct Wifi changing the Name and trying a Speedtest then .. All is OK But if you enable/disable Bluetooth again it stops working correctly.
It doesn't work anymore since B402.. And no solving solution found in this last update from Huawei.
Same problem here! since B402 update my wifi gets stuck at 0.5 Mbps if i have bluetooth turned ON. As soon as i turn bluetooth OFF my wifi works great!
Just updated manually with formware finder to version C432B404 and problem fixed!! Attention, it will update 2 version of the firmware: first a B404 normal, and then i get a new B404 (programmer) . Just updated both ad now everything works fine regarding internet speed with bluetooth on.
Had the same problem and it was the google home app for me. Uninstalled it and problem went away. Hope this helps for someone.
