Problem with Cyanogenmod 10.1/10.2 - Nexus 7 Q&A, Help & Troubleshooting

Hi all.
Previously i had CM 10.1 stable and it was all right.
Cyanogen Updater some days ago told me there war CM 10.1 Snapshot-M1 ready and i made the update.
From this moment, like other users, after the update i can not connect to any WiFi.
So, i reboot in Recovery and reflash CM 10.1 but now the tablet stuck in boot CM screen with the logo running, but it doesn't go to the home.
I can't do anything but looking sadly that danmed logo.
What can i do?
I neither can access the recovery, because i can not shut down the system...
:crying::crying::crying:

Please post such questions and help issues (not this one again, though) in the Q/A thread.

Can not install ROMs

Here are my problems:
1st and more important most roms wont boot in my u8800pro. I started with official 2.2.2 that came with the phone. I rooted the phone and installed recovery 5.0.2.7. Later I decided to try a different rom. I downloaded CM 7, kalo's, ics, MIUI (both gingerbread and ics). I installed CM7 first. After the update finished I rebooted the phone. It got stuck on the CM start/splash screen. Rebooted and the phone run. Unfortunately it kept powering off or rebooting on its own.
After that I tried all the other gingerbread ones. All of them get stuck on the start/splash screen. The one after the huawei flower thing.
All of the ICS ones load but I get no network for some reason.
Just to point it out I wiped data and cache and calvik everytime and I followed the instructions I found in the roms forum posts.
Atm am stuck with CM 7 and the random power off/reboot issue.
And that is problem no2. I dont mind using CM 7 if that can be fixed.
Any suggestions welcome
Well I managed to install stock 2.3.5 using the instructions in the #9 answer of this post http://forum.xda-developers.com/showthread.php?t=1405375&highlight=cm7+reboot+problem

[Help] GT-7510 wifi froze after working fine and rebooting continuously

I successfully rooted my Tab from ICS to JB 4.1.2 a few days ago and it has been working fine. It suddenly froze in GMail app this evening. Held down power and attempted reboot. All fine until several revs of the CyanogenMod circle then it froze for a few seconds and then blank screened and rebooted with the Samsung Galaxy Tab 10.1 logo before going back to the CyanogenMod circle. Only stops the looping if I power from the mains. Battery is at about 55% and charging.
I have CWM-based Recovery v6.0.1.5 and I installed JB from cm-10-20121112-EXPERIMENTAL-p4wifi.zip
Can anyone help? I'm new to rooting etc..
Many thanks,
Stuart
Try booting into recovery and doing a full wipe of everything.

Many thanks for the reply SouthPhilly. It didn't work
There seemed to be a problem with formating /data. It just stopped when I tried it. Also stopped if I tried restore. The good news is that I did eventually overcome the problem by following qbking77's excellent info on
How to Unroot / Unbrick the Samsung Galaxy Tab 10.1 - Latest at www dot youtube dot com/watch?v=KYBs98R9rTs with file info at
www dot qbking77 dot com/samsung-galaxy-tab-1012.html
which results in a stock original unrooted GT-7510. From there I rooted back into CWM recovery and reflashed CM10 so I'm back with a working version of 4.1.2
I hope this info may help others unfortunate enough to get stuck like me.
I'm now happy again.
Best wishes to all.

Well perhaps not quite so happy!
For some strange reason I could not get the USB port to work. It did with my first attempt at flashing to CM 10 - JB 4.1.2 days ago but not now. I have tried all ways several times so eventually I returned to the qbking77 version of the stock 3.2, copied my CWM backups back to the sdcard, then reinstalled CWM recovery and restored from the backup. I now have what appears to be a fully working tab with USB connectivity running 4.0.4 ICS again. I'll stay with this untill JB gets a bit more stable. You never know, pink pigs may fly and Samsung may issue an OTA update :laugh:
Why didn't you flash a nightly instead of a ROM thats dated last month? The latest one runs fine on my p7510

I didn't know where to find the nightly files when I first did the root and rom flash. I just followed the links I could find using google. The whole thing looked good to start with and I ran it for the best part of a week before it froze up on me. I learned a lot in the last few days and now feel confident in what I'm doing. I did download last night's nightly this morning and flashed the rom. When I connected the usb cable to my pc failed to connect so I reverted to my original zip file thinking the nightly had an issue. Low and behold the usb cable connection failed with this as well. In both cases I did all the wipes and formats just like the first time. After that I gave up and decided to try to put my Tab back to ICS using the CWM backup I made as recommended before I started the first time. I'm no novice as far as computing is concerned but I haven't rooted an android device before.
If you take a look around the forums here you will find I am not the first to fail to find the nightly files. Perhaps a sticky with the link would be useful?

[Q] Galaxy S4 I9505 stuck on CM10.2&11 boot screen wiped everything+reflashed!

My CM10.2 nightly was working fine for about 2 months or something so I didn't bother to update it to the stable version of CM10.2 because there is a problem with flashing roms where it would say stuff like cannot mount system/data/efs and I would need to wipe all the data before flashing a new update of cm10.2. But today, I flashed something that supposedly increases your phone's max volume and anything that has to do with volume(call, videos) was very buggy so I thought it's time to update my CM. So everything went smoothly. I factory reset, wipe systems and then flash CM10.2 stable with gapps. I was stuck at the cm logo for 30 mins and I reflashed+wiped all data 3 times. Didn't work. So I downloaded CM11 latest nightly and flashed it with android 4.4 gapps. Still same thing!! Have been waiting it out and reflashing cm 11/cm10.2 for about 3 hours now but nothing works! How do I fix this?
I have updated CM10.2 nightly many times and this is the first time this has happened.
Btw I only have a backup that was made like 6-7months ago on stock rom and I'm not even sure if it is corrupted or not.

bump... posted this on 3 different android forums for 8 hours now and no one replies to me.... Have seen replies to other threads of similar problems but not mine? I'm really desperate.

[Q] Cyanogenmod 12 latest nightly loop Samsung GS5 (Sprint)

So, I've been trying to root my Galaxy s5 for a while now and I just got it to work successfully a few hours ago. With that, I installed CWM and everything was fine.
Now, I downloaded the latest nightly of CM12 for the S5 and I threw it on my SD card and ran my phone with the up volume home and power thing, selected the zip and it's now looping. It's been looping for maybe 25-30 minutes. It stopped and said it was upgrading apps for optimization, rebooted and is now stuck on the loading screen for CM12.
I literally know nothing about CM12 or rooting or any of it, I just successfully did it today, so I'm extremely new and know nothing. I didn't factory restore my device, I didn't do anything fancy like that, the tutorial didn't say that I needed to, I just selected it and installed and rebooted.
I tried taking the battery out, and it's still doing the same thing.
Any help is appreciated.
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
