[Q] Help!! Flashed Cyanogen Mod on my Galaxy Mini, now have several problems!

Hi, I'm new to the forum and fairly new to flashing phones, although I fix computers so I was a quick learner.
Anyway, I have recently flashed my Galaxy Mini with the cyanogen mod I found in the galaxy mini developers sub-forum on this very site and come across a number of problems. Some of these I have fixed using my own best judgement and others, however I'm still having trouble "cleaning" the functionality issues.
For the record can I just say, I love the mod and my thanks and congratulations go out to all the devs involved. Well done!
So, my issues so far...
wifi issues - sometimes hangs on the obtaining ip address part
Android Market - installed both old and new versions (including the download link on the cm 7 thread) - installs fine then asks to create new account, I click ok and it closes the app
Creating sync accounts in settings - gmail, hotmail etc will not add (error: Setup could not finish. Unable to open connection to server
Downloading from internet - I have constantly been clearing the data and cache of the download app and browser and after a couple more downloads I have to repeat these steps. Anybody know a permanent fix for this?
Email: also not completing user accounts registration
I have searched and searched both this site and others for solutions to no avail. I love this mod and am very impressed with the tools included and my one wish is to be able to use it to the best of its ability. When I installed the update from sd card, my installed apps were also deleted (from the sd card), which I found strange, but thought hey, no problem if I can just download them from the market again right? But obviously since I cant run the market app, here lies my problem.
I hope there is a solution to this problem that doesn't involve reflashing my phone. I would be saddened to have to give up on this mod as I love nothing better than to get the most out of my phone.
Also just to clarify, I followed every step detailed in the CM 7 thread exactly as outlined and the flashing process was a pass for the cwm and the update completed successfully for the CM 7. I also cleared all data and wiped cache partition before and after each step as outlined.
Thanks for any comments/suggestions and I look forward to joining you on the forum.

No idea about wifi - not used it.
For market crashing, try this:-
Settings > applications > all > Market. Try clearing data from this.
You ought not have to create new account for everything. Creating /adding a single gmail account will work for email and market and address / contacts, google+, maps, etc.
Having to clear browser cache / data - I do not "download" much, but browse a lot - including the picture / video rich sites. Have not much problem, though occassional clearing cache / restarting the browser does help speeding up page loading. Probably has to do with low device memory. Did use other third party browser - like dolphon (opera is the reason I moved away from Nokia), but am back to stock html viewer now.

Thanks for your input. I managed to set-up gmail under the email app but it wouldn't accept my hotmail account (it used to before the mod)
I have lots of free memory on both the device memory and sd card. I also have plenty free ram. My phone runs like a dream now to be honest.
I have just tried an apparent workaround by installing youtube on the phone, however although I can use it no problem, when I try to add an account I get this - Unable to authenticate user (before it even asks me to input my information!)
This really sucks =(
I can't sync or download anything through market.

Also, I have cleared the data and cache several times to no permanent avail, as I mentioned in first post.

Wifi -issue...i have this sometimes.But even in official 2.2.1.And this issue is when reconnect at same brodband or at remebered wifi networks.I solve this issue sample.
-Turn of your phone Wifi,disconnect your brodband from power energy,wait 10 seconds,plug in againr brodband,wait him to load ~1-2 minuts,after reboot your phone turn on again wifi and manual connect to wifi.After auto-reconnect will work a wile with no issues.
For other sync email and contacts you need to isntall googleapps.zip via CWM at first run setup your Gmail acount.After no issue with others.
Also you need to make a correct install of CM and googleapps.zip.
1.)Install official 2.3.4 KPI using tools from samfirmwares.
2.)After install CWM using ODIN like in tj's thread http://forum.xda-developers.com/showthread.php?t=1167750
3.)Install CyanogenMod via CWM
4.)Boot up your phone and disconnect from 3g network and connect to wifi
5.)Reboot phone in recovery and flash googleapps.zip via CWM.
6.)Boot your phone and setup gmail acount.
7.)add your acounts and sync.
If you make this you shall not have any kind of issues with acounts sync ,only sometimes with wifi.

Hi, thanks for your suggestions - I've been waiting all day for a solution like this. I already have cwm installed as I said in first post. I will try reflashing as a last resort.
However, I am trying your theory on installing the google apps zip file through cwm now and will let you know how it pans out. Thanks!

Damn. Always something goes wrong! Log from cwm ; Finding Update package>Opening update package>verifying update package>E:signature verification failed>Installation aborted. Grrrrr
Previous installations have been fine through the choose zip from sd card. However, on attempting another zip (flash 10.2) also doesn't verify either (worked before)
Whats going on?? I'm at my wits end =P

You can toggle "signature verification" in CWM recovery menu. (Not sure where exactly that option is - but recovery menu is not too deep.

All, I am using CM7 for Galaxy Mini 09102011 and I have ony one problem:
Somehow the MAC address of the Wifi device in the phone is changing every time I disable and re-enable Wifi connection. This was a problem, since because of that I had to disable MAC address filtering in my home network just to prevent myself always setting the new MAC address in my router's MAC filtering "white list".
What I observed that the changing part of the MAC address is always the 2nd half (meaning the last 3 pair of hex numbers)!
Does someone know a fix how to prevent Wifi MAC changing?
Some people say that the don't have this experience with the previous release of CM7 for Galaxy Mini (01102011).
Any ideas?
Thanks in advance,

I haven't noticed this kind of problem before with CM7 personally and I wish I had a fix for you. Perhaps it may be better to back up and try a reflash? Assuming you haven't already tried that of course!
Sorry I don't have any other methods but I noticed nobody is replying to your question!

Yes, this problem is not there in CM7 01102011. You can try flashing it after a nandroid backup. I had similar problem with latest (09 10) CM7 so I restored my previous backup and everything is fine now...

[Q] How to reset gallery thumbnails (CM7)?

Hello!
System info:
I've got SGS GT-i9000 with CM7 as my firmware and GO Launcher EX as my default launcer.
Introduction:
Everything has been working brilliantly, but now I've run into an annoying problem. I recently installed couple of emulators (SNesoid, Nesoid...) and as I play them, I like to take screenshots from the games I play. There is a built in screenshot function in the emulator which I use (instead of the OS one), which saves the images to a "screenshot" folder (notice: it is not the same as "screenshots" which is the OS's folder).
The problem:
Since then I have noticed that most of my gallery thumbails have been replaced by the thumbnails of those screenshots found in the "screenshot" folder (which was created by those emulators). I don't know for sure that these things are related, but it seems weird that this new screenshot folder had my gallery thumbs all messed up.
So finally, the grand question is: how do I reset my gallery's thumbnails? Is there a specific cache folder or something where the system stores all the thumbnails, which I could easily just erase and start all over again?
I googled through the FAQ and made a forum search but couldn't find an answer to this. My apologies if this question seems reduntant, but I'd like to find the solution for my problem.
Thanks!

I think you should go to: Settings->Apps->ALL->Gallery->Clear data...
Let me know if it helped you

CM 10.1.3 - Cannot open PDF or Videos

Hi,
I recently installed the 10.1.3 and I love the stability of the ROM. I recently tried to read some magazines on the Nook & I'm facing a peculiar problem where I cannot open any PDF files, EPUB or even Video files. I tried putting the files on the Nook memory and the SD Card too. All Apps (Aldiko, MX Player, etc.) return back the error "Could not load file".
I can't seem to understand what could be the problem here. All files work well on the computer, but nothing on the nook. Could it be a file permission restriction?
Any help would be much appreciated.

I can't help but I am also running 10.1.3 and don't have your issues. I didn't change any settings other than for the launcher. Could there be a problem with the gapps version you installed?

Open the web browser and if you can read a normal pdf and view a video from youtube then your files are simply not compatible.
Suppose they could be getting corrupted. You didn't say if you tried them from the computer via the sdcard.

I transferred the files from the computer to the internal memory and the SD card, but to no avail. It says "Video could not be loaded" or "File could not be loaded", if a pdf does load - it usually comes as a blank white screen.
How do I check if I have installed the correct Gapps version? I did try and open a pdf from the web browser, I faced the same problem.

Go into Google play and download "Foxit MobilePdf". You should be golden.
[I may have forgotten earlier, that possibly all mobile web browser's can't view pdf files, or at least the one(s) you have can't do so. For instance, Firefox downloads them, but can't view them. You would still need a viewer, which I think you never installed one on android and hence your problem.]

[Q] Can't record or play video in 6.0 Marshmallow concept

NOTE: I know MM is still in beta and there will be issues and bugs. But for most the most part it is an amazing rom and it seems like nobody has this issue except me...
After booting into any version of MM (2099 -2134/Viperx) everything seems fine. But after a few minutes i lose the ability to record or playback video. All across the device (video in facebook, youtube) i get errors or black screens. When playing video in gallery I do get sound but with a black screen. Clearing cache of camera or any other app doesn't help. Only a reboot gives a temporary solution, because after a few minutes it starts all over again.
errors:
Camera: after 1 sec. of recording ' unknown error'
Youtube: ' There was a problem while playing touch to retry'
I always do a clean install of new ROMs, and did a factory reset+reflash multiple times, but to no succes.
Any help?

For anyone still having video playback/recording issues: I found this possible solution on a Xperia z2 forum. I still have no idea what is causing the error or how this fix works. But 24 hours later everything seems to be working.
Here is the original post:
"I assume you unlocked your bootloader. I was also having this problem before. Try renaming these files on /system/etc/firmware/
tzwidevine.b00 -> tzwidevine.b00.bak
tzwidevine.b01 -> tzwidevine.b01.bak
tzwidevine.b02 -> tzwidevine.b02.bak
tzwidevine.b03 -> tzwidevine.b03.bak
tzwidevine.mdt -> tzwidevine.mdt.bak"
Maybe someone can tell me what this fix does?
Anyway use it at your own risk, but it looks promising.

Just to let you know, I'm experiencing the same bug over and over.

For anyone else who was having problems with playback (of old recorded videos) on Concept, I've pretty much isolated the problem and have a solution. I should mention that I only had problems playing back content that was recorded by or stored on my phone. I had no issues with YouTube or any other online media so this fix is specifically for those who can't view their own personally recorded videos through the stock video app.
I noticed that any video I recorded and stored on internal memory played fine, but anything stored on my external SD card resulted in the error message: Cannot Play Video, so I tried moving a video from my SD to my internal and voila, it played fine. In order to remedy this, I simply formatted my entire card as internal by going into Settings > Storage & USB > my SD > 3-dot menu > Format as internal. Everything works as it should now.
WARNING: Formatting your card this way will delete everything off your SD card so make sure you back up first!!

Thanks GoreGaard but how to find their location? I look up via TWRP and failed to locate the files....do I must root first and use root explorer just to find the files?

Oh found it ... must use root explorer first usually I just restart my Z3 D6653 when I experience black screen during youtube and then it's normal again. But I will try to rename those files now and see how long it can go normally.
Btw I use MM concept 3657 on D6653 and working good, fast and I like it

Guys, audio while video recording is too low....is it because of Concept it self?

My story...for what it's worth...
I first installed Concept on an unrooted, vanilla mm, z3c - and everything worked flawlessly.
I then rooted it using the giefroot_v3.1 root exploit (which requires downgrading to fw 23.0.A.2.93, or prior) re-installed Concept, and had the same problem with video recording giving an error message.
Luckily I had made a backup of my DRM keys during the rooting process.
I restored them.
Re-installed Concept, and now all is well again....

renaming the files worked for me on my z3 compact with the newest concept rom MM. unlocked bootloader, Xposed and TWRP.

Question [HELP] Can't open pdf and other files on some apps

Hello people it's just to report and see if any of you have faced a skmilar problem and how To solve it.
The main problem is that all files pdfs, jpgs or any other that are sent to me via WhatsApp it's impossible to open with any app. All apps say the file is corrupted or something like that. The same happens with Edison Mail (app) I use it to have all my mails synced, but the same happens all mails that contain attached files are imposible to open the external apps to open pdf or image files say it's impossible or file corrupted.
Nevertheless, and the main thing is that those files are NOT CORRUPTED whatsoever, if I look for the files on the internal storage and open them with any of the apps that said that the same files were corrupted, the files open without any problem.
I was going to reinstall WhatsApp, but in the end I didn't because it's really time consuming to make a backup and because I realized it was happening with other apps (probably with others I haven't come across).
I have checked permissions, disabled /enabled them but with no luck.
Any thoughts or similar experiences? Any workaround?

This problem isnt occuring for me. It opens for me fine. Maybe it could be an issue with the pdf reader?
What do you mean when you say, it is impossible to open pdfs in external apps?
Im assuming you have tried different pdf apps as well? Try opening the file from the pdf app itself, as in navigating to the file from inside the pdf app, rather than opening it directly in whatsapp.

Sorry if I wasn't clear enough.
If I open the files directly from the pdf reader (I've used several, acrobat, xodo, drive, onedrive, etc) or opening the files from a file explorer (solid explorer, xiaomi file explorer) they open, they are not corrupted.
The problem is when I tap on the attached file on the whatsapp chat or on the edison mail (app) The prompt to select an app to open the file shows up but no matter which one I select it will FC or say the file is unreadable or corruupted (depending the app). That is why I believed the problem was regarding some permissions in whatsapp or edison mail, but I've enabled and disabled them with no avail.
If you google this problem, hilariously you can find a very similar one on an Adobe forum but of course there's no solution because the adobe won't provide a solution that is not directly caused by their apps. The only good comment there is that apparently it's an andorid 11 problem on MIUI devices.
Some mention to disable MIUI optimizations, which I've already tried enabling and disabling because I usually have them disabled.

The only good comment there is that apparently it's an andorid 11 problem on MIUI devices.

Yes, it certainly seems like an miui problem or the A11 problem. Okay, do one thing, try opening the pdf file via chrome browser, or any other app, maybe gmail app.
Also, before you do that, download matlog to log what happens, maybe we can try pin pointing the issue.
If its just an app thing, then maybe reinstalling should fix it. But i doubt it is. And the only real possibility seems like reinstalling the rom.
Heres a suggestion, since we dont have twrp yet.
Download the latest full rom, a few issues happened to me earlier, when i installed miui in one of the incremental updates.
So, what i did was, downloaded the entire recovery rom (not fastboot) and just updated the system via system update by locally installing it.
Just google how to local upgrade on miui if you're not clear about it. As i wasn't since this is my first miui phone.
This would essentially dirty flash a stock rom, and should iron out any issues without having to reset the phone.

Is your MIUI optimisation option disabled in the developers options? If so, try enabling it and try to open the files again.

Here are the logs. Actually by doing so, I discovered that also sharing a zip file from the matlog to any app to upload or share it (whatsapp, gdrive, onedrive, etc.) also resulted in an similar error (this part is not included on the logs).
The logs include trying to open one file in two different apps. Gdrive pdf reader and Xodo.

Actually I hadn't tried that, Just did and leaving MIUI Optimizations enabled makes the problem disappear, in fact, the promt to select the app to open the file is different.
But what if I want to leave MIUI Optimizations disabled?

I don't think there's a solution for this. I think the best workaround for this problem would be switching to Xiaomi.eu rom (since they have MIUI optimisiation disabled by default) but it's still not released yet.
I could be wrong though.

Im assuming the miui has its own code for the app selector and the underlying android 11 app selector code is disabled. Probably to speed up the process of switching apps. Maybe if there is a way if you can enable the original android 11 code for it then you could disable the miui optimization setting. But then, if this is just for the app selector, there could be other underlying issues, that you might have not have experienced yet where miui uses its own implementation and has disabled the original android implementation. I wouldnt recommend that unless you decide to switch roms to the EU version for this specific issue like @brzi6 mentioned but i think theres no point as it could cause other location based hassles.

Firstly, miui optimization is garbage anyway.
Secondly, the problem is with app permissions. If you can get your pdf viewer of choice to have access to your file system then all will be well.
