I've noticed other people seem to be having this same problem and there hasn't really been a distinct solution that I can see, so hopefully this question will be helpful in the future and not repeatative.
I've been trying to update to CM7 from CM 6.1.2 on my Evo. I followed instructions from here http://forum.xda-developers.com/showthread.php?t=902051 and downloaded all the recommended software. First I tried to just flash the rom, then the kernal, then the gapps. All seemed well at first, and I got past the Evo 4G screen, but it got stuck booting on the Cyanogen animation (the arrow just keeps going!)
Then I tried to wipe the Davlik-Cache, and rebooted again. I left the phone alone for about 45 minutes, and it still got stuck on the Cyanogen animation.
Finaly, after searching through the forums, I found another post which suggested I do a hard reset then flash the rom, kernal and gaaps then clear the cache and davlik-cache. Still, I'm stuck on the animation. I have a nandroid backup, so I can get back to 6.1.2, but I'd really like to get CM7 working, anything else I should try?
You should't have to do the kernel separately unless you have a specific reason for doing so the ROM comes with a kernel for you. I had a similar problem with my HTC however I was able to get it resolved by installing gapps. Here's what I did -->
Used ROM Manager to go back to working ROM
From working ROM, accessd ROM Manager and chose rebooted into recovery mode
Once in recovery cleared/wiped everything (cache, data, delvik) installed gapps then cm7
Restarted
It did take awhile after restart to get going however once it did it worked marvelously!
Hope this helps and good luck!
Reboot
Similar Problem, Defy CM7 Bootloop
The first time i tried installing CM7 I got a boot-loop. I have tried at least 7 different tutorials all with different variations of flashing this and wiping that yet none yield results. Still stuck at boot-loop.
The most recent thing i have done was used RSD Lite to flash
"JRDNEM_U3_3.4.2_179-002_DEBLUR_SIGN_SIGNED_UCAJRDNEMARAB1B80AA03A.0R_PDS03C_USAJRDNFRYORTCEE_P016_A016_HWp3_Service1FF.sbf"
this got my phone running again, i then pulled off some magic by rooting using a combination of super1click, Z4 and installing superuser myself. after that i copied the files for a bootmenu into my /data/ folder. using CWM Recovery v2.5.1 flashed
"freq_F_US_342_107-850-1700-2100-signed.zip"
to get my 3G running again, and gave up of CM7.
If anyone has anything that could help id appreciate it.
(ps. i've tried many variations of wiping things and re-flashing things)
I have tried all of the ICS roms, and always gets stuck at the same spot. Wi-fi is turning on.
It worked on the Revolver 4, but I wanted to try another one. Did a super wipe, and bam. Nothing after that..
Any thing I might be able to try?
Nandroid restore, if that won't work nvflash?
you mean use NVflash to do the rom install vs the recovery?
I made a topic about this, check my post (not able to give you a link right now sorry)
I also need help with this. I am trying to come from CM9 cornerstone build back to revolver. I have done a couple restores and I still get no WIFI. Anybody have anymore info on this?
Have a look at this : http://forum.xda-developers.com/showthread.php?t=1530612
You can try this:
- Turn off wifi
- rename the file /data/misc/wifi/wpa_supplicant.conf to wpa_supplicant.old
- reboot
- try wifi again to see if it works
**note
This might cause the tablet to forget any previously saved networks.
I have tried Outpoxs' method in varies combinations with no success also I have tired your method a.mcdear and also with no success. Mine is still stuck on Turing WI-Fi on... The one thing with outpox method there might have been something I was doing wrong.
This is how I fixed my tablet after 15 hours of trying everything. I downloaded the ota rooted full version of ics and performed a full wipe then made sure it booted into that rom with wifi working then proceeded to flash my revolver backup with no problems. Hope that helps.
Similar WiFi issue - still stuck
I hate to bump an old thread, but I've recently hit what appears to be a related issue (WiFi stuck off), though perhaps there are some twists to my tale - and I'm still stuck.
I have an early TF101 (B50) and have had it rooted with stock ICS for awhile. Everything has been mostly fine, but I decided to give CM9 nightlies a try.
Here's where my issue differs from the others in this thread. With the CM9 nightly flashed, I was stuck at the boot animation (for hours - left it overnight with no progress). I restored my nandroid backup and now I had the "WiFi Turning on" issue that others here have experienced.
I've tried multiple other ROMS (latest of AOKP, Gummy, and Prime 1.6), with complete wipes, and in each case, I was stuck on the respective boot animation. This completely mystifies me, but it may not be related to the WiFi problem. After each iteration of failed ROM flashing, I can restore my nandroid backup (the rooted stock ICS) and everything works fine EXCEPT WiFi.
Following the suggestions in this thread I've tried flashing a new stock ROM (from http://forum.xda-developers.com/showthread.php?t=1514658) and while that doesn't stick at the boot animation, it also doesn't fix my WiFi. I also tried a.mcdear's suggestion in http://forum.xda-developers.com/showpost.php?p=23446585&postcount=7, but I did not have the file wpa_supplicant.conf in my /data/misc/wifi directory. The only file in there was an empty file called "status." Just for good measure, I tried renaming it, but no joy.
At this point, I'm out of ideas and have a severly crippled TF. I would appreciate any suggestions or ideas from the community.
TIA

I've have a rooted TF101 B50 and most ROM's that I have tried seem to fail at this point as well. However, I did notice that when I flashed my first ROM (AOKP) it has the same stock kernel. So I tried another one. This time was Revolution 4. It seemed to work out just fine because I belive it has the stock kernel. Next I moved onto a CM10 Eruoskank ROM. It too had the problem of the AOKP ROM in that after I flashed it, the stock kernel was still present, presumably left over from the Revolution 4 ROM. I am now on Android Revolution HD 3.5.0 and it seems to work fine so I am sticking with it for the time being.
I beleive something in the flashing script of the ROM or the recovery program itself is not flashing the /boot partition properly. I am not a developer nor do I have an in depth knowledge of the inner workings of Android...but this is just a guess. I hope there is a way to flash just a kernel in the /boot partition from these individual ROMs. That would be nice.
If can access recovery then do a full wipe(system, cache and dalvik) and install the ROM again... that should do the trick... you might wanna try some other kernel also... there few kernels for ICS in the forum look for them and flash them via recovery...

It seems as thought someone else is on the same track as I am.

rstry this:
take unit out of dock if you use one. restore via cwm if u can, to 3.01 firmware, honeycomb. wipe all cache, data, etc prior to flash.
DO NOT SIGN INTO GOOGLE ACCOUNT.
Turn tablet completely off following boot. Cold boot back on. Grab latest official firmware off Asus website, xx.27
Install via CWM, and again wipe ALL.
Boot into system again, and cold boot back on. Asus should prompt you with 300mB update now, which differs from the official .27,but had same filename...
I found this bug/glitch a few hours ago... Somehow downgrading to HC and back to stock triggers this unknown update...
See if you can reproduce please. I also saved the firmwares to sdcard external.
The various ROMs require a supporting kernel. I would try obtaining the correct kernel for the ROM you want and then flash them both at the same time from recovery.
Resolved - for me
From replies here and other research, it became clear to me that I should reflash my transformer back to stock (NVFLASH down to the metal). Every other ROM would show the stuck WiFi issue or (worse) would get into a boot loop.
This was something of a problem, because my volume up button was broken and I couldn't enter APX mode. I finally managed a workaround for that (see http://forum.xda-developers.com/showthread.php?t=1890236) and then used EasyFlasher to restore the Asus firmware. Now the WiFi works fine and all is well again.
So, as a last resort - scrub and start over.
Cheers!

I also have the same issue. Bought the eee pad transformer with a cracked screen; touch screen did not work. I replaced it and everything works great! except for Wi-Fi =\ Any help would be greatly appreciated!
You should really start your own thread. That being said, first thing to try is to back up all your data and wipe it to factory using EasyFlasher. If the problem persists after a stock firmware flash, then it's likely a hardware issue. If it's resolved, then it was a rom/software issue.

Im 99% sure your problem is that you haven't got the right kernel for the rom your using, this is the usual outcome - wifi not working/ turning on. i don't think nandroid backs up the kernel so your basically restoring stock ICS rom with cm9s kernel. Try find the related kernel to rom your currently on. As for your rom failed flashing, you might be using a very old recovery try updating to the newest twrp recovery. Better yet join the dark side and move up to Jelly Bean, makes the tf101 a whole new device.
I was happily running along with my GT2 10.1 5113 using CM10, updating nightlies, all is well. Then I put the CM 10.1 unofficial, that went well, was using it and put the 12/09 version on, that went well also. However I decided I didn't like it and wanted to go back to CM10. I had a back up that I made in CWM with the 12/08 nightly and had begun restoring it when an error came up stopping the restore, only said file error restore can't continue. OK, that kinda blows chunks cause I know my rom just got hammered. Tried to restart, boot loop. Got back into recovery re flashed the CM 10.1, trying to save my data, bootloop. Got back in recovery and wiped data re flashed, bootloop. On an act of desparation I flashed the 12/08 nightly and, viola she lit up and booted to the setup screen.
Set it all back up and updated to the next nightly, 12/10 and I'll be danged, bootloop. Went back to recovery re-flashed the 12/08 nightly and all went well. No data loss just worked fine.
Bottom line I can't get anything but the 12/08 nightly to boot up. I even flashed stock with Odin, that bootlooped too! So I'm stumped.
It boots into the 12/08 nightly just fine and that's it.
I know this is wordy, but I wanted to make a thorough explanation. I feel this is related to the CWM error, but I have no idea where to go from here.
Anybody got a suggestion? All help is greatly appreciated.
I think cm10 installs jelly bean on your system. and switching back to an older version will cause the bootloop. that's what i believed happened to me when I installed cm10 by mistake instead of cm9 which is what i wanted. it took me several tries with odin and the stock rom to be able to go back.
I think the key is when you have cm10 installed then you need to enable the "usb debugging" in the developers section. that is probably what is stopping you from switching back to an earlier version or a new version or the stock rom using odin.
anyway that's how I was able to switch back to stock.
I think the reason you can´t restore CM10 is the fact that Android 4.2 introduces muti-users management. Thus, the system do not store in /sdcard/ any longer, but in /sdcard/0/ (for the first user). Since you still have a 4.1 recovery version, it doesn´t find the backups files any more. A solution is to move your sdcard data from /sdcard/0/ to /sdcard/ before restoring your backup.
As for CM10, the 12/09 and 12/10 nightlies don´t boot, due to kernel changes. These changes were reverted in 12/11, so this one should boot.

Bingo! That worked, 12/11 worked. I had no idea that was happening. I made all the file changes actually because I wound up with sdcard/0/0/0 from all the flashing back and forth, that was funny. All is normal now thanks!

I have been running CWM recovery and installing Wingray nightlies on my MZ604 without any problem for more than a year. A couple of days ago I flashed what I think was a partially downloaded ROM. This soft bricked my Xoom (somewhat unsurprisingly). I ended up in a boot loop so I used this method http://www.xoomforums.com/forum/motorola-xoom-development/18743-how-flash-sbf-rsd-method.html to get out of it.
That worked fine leaving me with a stock Xoom running 3.1.
I then unlocked the bootloader and flashed CWM Touch using adb. I then booted into recovery and flashed the universal Xoom root from here http://forum.xda-developers.com/showthread.php?t=1242241.
Again, this worked fine so now I had what appeared to be a fully functional Xoom running CWM Touch and 3.1. So far, so good.
The final step was to install a recent ROM so I booted into recovery again, flashed the latest Wingray nighly and the GApps package as I have done on numerous occasions (after doing a factory reset and wiping the cache and the Dalvik cache). This appeared to work just as it has always done but now my Xoom just sits at the M logo and nothing else happens. I can still boot into CWM Touch but my Xoom won't get past the M logo in normal boot.
Since everything seemed to work exactly as I would expect right up to the final boot, I'm somewhat mystified as to what is wrong. Can anyone give me any suggestions as to what to do next?
Now I can actually help you. I saw this a day ago but did not respond yet because I did not test my method.
It's been stated by a few in the eos 4 wingray thread that nightlies 204-205 are TEST builds. Only one person said that but from what everyone else is experiencing this appears to be true. You are not alone mine was bootlooping and never getting past the splash animation either.
You don't need to fix or flash a new recovery. All you have to do is use a lower build such as 203 and you'll be fine. I'm testing some roms right now and they work fine now. I did upgrade to twrp recovery as well.
I'm sorry you went through the whole boot loader process again.
At least it's a simple fix. I'd recommend monitoring the eos4 thread and see when people post about newer builds working. I'm sure 206 will fix everything.
Best of luck.
Thanks for the suggestion but unfortunately it didn't work. I did get past the M logo and the multicoloured splash screen appeared but it just got stuck there.
I tried going back to 203 and that didn't work. I also tried going way back to 155 (with the appropriate Google apps package) and that didn't work either.
I am starting to wonder if there is something about the way I am flashing these that isn't working. I have done it so many times that I am rather baffled as to what is going on this time but I think I shall try flashing using Odin and see if that gets me any further. It's all rather frustrating as I haven't been able to use my Xoom for days now.
I have now fixed this although I am not absolutely sure whether my diagnosis is correct.
By flashing Wingray 203 and a very old GApps package, I got past the splash screen. The Google setup program then crashed but at least it had booted. I then tried 203 and the second most recent GApps package (dating from January I think) and it worked.
My guess is that there is some weird interaction between the most recent versions of Wingray and the most recent GApps package (and possibly other factors) but at least my Xoom now works.
Okay so i have TWRP 3.0.2.0 modded for multirom and multirom installed on my phone and it was working okay for a long time now all of a sudden my phone randomly reboots and ALL 7 roms in mutli rom boot loop when you try to boot them. so i erased all of them and reflashed the rom, the second i flash anything other than the rom, kernel,mods, stupid files, literally ANYTHING but the rom it bootloops again and it never did this before all of these files worked together before, so i rewrote the twrp and mutlirom and all, figuring maybe that would help, it did not. so i thought okay, fine i will do an RUU and go to stock. it says the firmware is mismatched? so because of S-ON i cant restore to stock now. ( same one ive been using to RUU it for over a year anytime necessary )
literally everything i try i just end up with Bootloops. if i flash ONLY the rom it boots fine but the kernels tend to kill the battery really bad so i usually flashed a custom one and i just dont understand how the same kernel and files ive been using for like the last 8 month now are bootlooping every time. i tried looking for new roms too, nothing works. i also tried plain stock TWRP and no mutlirom, same results, bootloops if anything more than the plain rom is flashed.
also my battery seems to be dying like a rock now, unplugged it and within like 10 min i had lost 18%

Try a different twrp version worked for me awhile ago when I had it
Thank you for the suggestion but as it says above i have tried that. this phone will not let me restore or use anything without google play now so im probably just going to get rid of it or smash it because ive been trying for weeks and NOTHING works.
only android 7+ roms boot, cant RUU, no home button menus, notifications or anything work without google installed so my phone has some weird new firmware on it and is forcing me to use the most up to date android/google play or it just wont work at all.
Update: charger port just quit working, probably burned up from getting so hot with all the battery over use, phone is officially dead now.
