[Q] Never Ending CM10 Boot Animation - Nexus 7 Q&A, Help & Troubleshooting

I install nightlies of CM10 onto my nexus 7 original 16GB every time one is released (which is probably not a good thing but there you go) and i upgraded from the release on 15/12/2012(4.1.2) to the release on (4.2) (I missed a day) but when i had installed i couldn't open Google Play Store which was strange and my favorite live wallpaper 'Microbes' wasn't on the device so i tried to downgrade back to the nightly from 15/12/2012 which was still downloaded on my device. This went smoothly until it came to the first boot where it has been stuck at the CM10 boot animation which is spinning but doesn't stop.
Does anybody know what has happened that could help me? I think it might be something to do with downgrading from 4.2 to 4.1.2. Also i use the CM Downloader that is built into Settings > About
Thanks in advance

EDIT: I fiddled around with the buttons and managed to get it to restart booting but it is in the never ending boot animation again
EDIT2: I booted into recovery and then installed the nightly from 17/12/2012 and it is working to the same extent that it was before i tried to downgrade

From these and from what i've found when fastboot flashing, i suspect that the either the bootloader changing when upgrading to 4.2.1 from 4.1.2 or the kernel changing caused you the trouble when trying to go back. if you want to check, you could try going into fastboot and see what bootloader version you have, and then try going back to the 4.1.2 build and checking that again. next, compare these with the bootloaders for stock 4.2.1 and 4.1.2. I suspect that in order to move back you would need to do what you did to move back to 4.1.2, then use fastboot to flash the older bootloader to allow it to work. But i'm not certain on that.

and you tried wiping data(factory reset) and reflaahing?

[Q] Nexus 4 boots with 4.2.2 (JDQ39 but no radio) but no new ROM, including stock

I am facing weird issue with my Nexus 4.
All of sudden it stopped working. Won't go past X logo. I tried flashing stock images, didn't help. Though to flash backward, went for 4.2.2 JDQ39, it worked but no radio. Did factory reset, cache cleaning and all but no avail. Whenever flashing newer builds then it won't go past X logo and if JDQ39 or older then no radio. Multiple flashes done, no avail.
Tried flashing latest CM nightly as well (August 26), but that's also not booting beyond the logo in hours.
Any suggestions????

doing a system wipe (factory reset) when you update from 4.2 tp 4.3..? also just reminding you 4.3 based roms need new radio and bootloader update.. but that radio also works with 4.2..
Same problem

I am having the same problem, it sucks
the radio doesnt work, i think, because the IMEI is unknown, well at least on my N4

You are doing something wrong, its pretty hard to brick a nexus. What recovery do you have installed? have you tried using ADB or even a toolkit?
i dont think i have a solution

So I've heard that its hard to brick, but my phone isn't bricked, far from it, because I can use it it boots and everything (I'm on 4.2.2) and I'm replying to you from it now, but I'm on my homes WiFi because the phone doesn't read my Sim card, or at least that what I initially thought, but after some research I found out that its my lack of IMEI that's causing the problem. Even when I go into settings and about phone and look in there, both baseband and IMEI say "unknown" but when I boot into fastboot its a all there.
Regarding your question about adb and toolkits and my recovery
1.) I've tried adb as well as fast boot and wugfreshes toolkit to try and solve the problem
2.)I am completely stock 4.2.2, and that includes the recovery.
PS I used to be rooted and that was it, but after I had gotten stuck in a bootloop I flashed 4.2.2 and that got the phone out of Tue loop but now the IMEI and baseband is 'unknown' rendering my phone essentially an iPod type of device

radio .84 causing my phone bootloop

I had used cm 10.1 for a year and one day I decided to flash slimbean 4.3 weekly 1.4. So I downloaded bootloader Z20i.zip and radio .84.zip and flashed via TWRP 2.6.3.0 and then wiped everything, flashed rom then gapps. I used the original kernel of rom. Everything seem to be fine and flawless. but one day my phone hanged and rebooted itself stucked at bootanimation. I tried to restart many times and it didnt success. So I decided to download factory image JWR66Y from google and run flash-all.bat via fastboot mode and then flash superSU via TWRP. Yeah..bootloop was gone. I used stock JWR66Y rom and kernel with root for a while and it happened again. One day my phone hanged and rebooted itself stucked at X animation. I tried to Wipe cache, davik, factory reset but it didnot success. So I tried to install cm10.2, PA3.99 (I have had installation zip file in my phone storage.) but it didnot sucess too. So I decided to flash stock Stock 4.2.2 JDQ39 image from google. thanks God my phone resurrected. But I dont want 4.2.2 anymore. I decide to try again with 4.3 stock JWR66Y. It happened bootloop same as above I described again. I have no idea anymore but I tried flash radio.48 via fastboot and finally my phone can use normally. Bootloop was gone away. Now I use Slimbean 4.3 weekly 1.6 original kernel with bootloader z20i and radio .48 without any bootloop.
So I think the problem for me is why radio .84 make my phone got bootloop.

I have the same exact problem! :crying:
Cannot update beyond 4.2.2. I have tried all the things that you seem to have tried but with absolutely no luck. And since there aren't many people with this problem, nobody has come up with a solution. It is extremely frustrating to see everyone else updating to to the latest firmware while we have to make do with the ancient 4.2.2
If anybody can think of anything which might help, please go ahead and share.(Cannot return the phone back to Google as I got it from another country)

Hi,
I just fixed a Nexus 4 with broken screen and fastboot flashed the latest 4.4.2 official ROM but I was stuck in bootloop on the 4 circles.
Then I flashed the 4.2.2 version and everything worked until I accepted the the 4.3 update (official OTA) and the phone was bootlooping again.
Then I found your posts and downgraded the radio .84 to .48 and android 4.3 finally booted successfully.
BUT, when trying to upgrade to 4.4 (from 4.3 with official OTA), I'm stuck again! And downgrading radio .97 to .48 does not work anymore...
I've found nothing like a software fix until now. People facing the same issues are mostly getting some replacement devices. Given that I replaced the screen myself, I'm not certain that they would give me a new one.
Any feedback from someone having the same issue?

Well, I meant I could get 4.3 to work after downgrading the radio file (baseband) to its previous version, otherwise I was stuck in bootloop in 4.3 already.
But I couldn't do the same operation after flashing 4.4 : even downgrading the radio to a previous version didn't get 4.4 to work.
Once I reconnected the proximity sensor, I could use any radio and was able to update from 4.2 to 4.3 and 4.4 or directly flashing the latest.
You can use the Androsensors app to see if your light and proximity sensors are working properly, the displayed values should change all the time. If they are not changing or if there is no value displayed, it means that your sensors are not working properly

You should change the title to "Screen Damage after updating Custom rom/kernel".
This is one of the risks in installing custom software and drivers is that it might get flaky. I would recommend flashing an older Kernel or one with an older screen driver as the new one doesn't play nice, apparently.
The Touchscreen graphics driver is a weird one. It generally can be updated... but not downgraded easily. The Nexus 7 2013 has a big issue with its screen and they've had to force a custom driver in it and lock it from being updated (since an Google Update installed a bad driver). It's been fixed now, but a bad problem. I doubt it is exactly the same since ours affected touch inputs where yours is affecting color, but pretty sure its the same chip that controls it.
Flashing an older Kernel will likely NOT fix your issues but it is worth a shot. You may have to wait until the developer puts out a patch (to update).

Back to stock rom, hanging when placing call, no sound etc.

Hi there
I have recently picked up my old S4 since my OPO screen broke. I was annoyed with the buggy CM 12 nightly it was running and tried installing the newest CM 13 nightly. It gave me no signal and I decided to try to revert to stock, following the guide Unroot/Unbrick, Flash official stock firmware on S4. Applying the I9505XXUAMDE_I9505OXXAMD8_NEE 4.2.2 stock rom through ODIN was a breeze but after booting i realized it had no sound.
Also placing or receiving calls makes the phone hang, even occasionally reboot, and sometimes a window with "android.phone.. app" or "process system is not answering" appears. For example also not possible to record video.
I did both factory reset and wipe cache in bootloader, but when wiping cache I get the lying down android with red exclamation mark for a few seconds then reboot.
I then tried to reflash above stock rom with repartition (pit file) and the problem remains.
I dont suppose it is a hardware problem since it started after I flashed new rom. It seems like some audio related software issue that I cant seem to get rid of - can anyone help or should I just give up and get another phone?
Thanks in advance, sorry for the long post
Try flashing a newer ROM.
The guide used is pretty old I guess and should be used only as reference.
What was the initial stock ROM your device had?

I already tried rerooting and flashing back to both CM 10.2 and newest CM 13 nightly from philz touch recovery. Both with the same problem when placing or receiving a call. But sound was working..
I don't know the exact stock rom the phone came with but seem to recall it was 4.2.2 as I have installed now.
Is there anything else that can be flashed back to original? I read several posts talking about a modem reflash for fixing audio issues but I suppose the stock rom should contain the modem info already..?
I specifically went for the oldest rom, since the guide said that once stock 4.3 is flashed you cant revert due to new bootloader. And I was hoping to revert to being able to use OTA updates since I plan on gifting the phone to an even more tech illiterate than myself.. Is that going to be a problem if I just flash for example the newest 5.0.1 stock rom?

Downgrading causes problems in the first place, that is why it is recommended to flash the same software as it originally had.
As long as your status says "official" in download mode, you should be able to still get updates. Although who knows for how long.
I also recommend using the latest TWRP recovery. PhilZ and CWM are outdated and can cause problems with newer ROMs.

Nexus 10 stuck in boot animation even after wipe/sideload

I dug out my old Nexus 10 (mantaray/manta) to mess with it and firstly it booted up fine and I updated Android to 5.1.1 (system update). All was well. I was going to flash Pie onto it, so I booted to the bootloader and connected it and unlocked it via fastboot oem unlock. Ever since I did that it will not get passed the boot (colorful balls) screen. I can get back into the bootloader. Next I cleared the cache and then also did a factory reset, same issue. So I flashed the official 5.1.1 (LMY49J) image, and still have the same issue!
No clue how to get to some state where I can boot this thing. My end goal is to have Android Pie / vanilla on it. What should I do?
Edit: I think what I did was I flashed an update rather than the full OTA. I can't find it, so maybe someone can point me to it?

Mine does it aswell, but after like 20 min it boots up. I flash mine with the "Nexus Rool Toolkit" with the option "Flash Stock + Unroot", in your case i wull put the radio button on "Softbrick/Bootloop". Then follow the steps on the screen and then when it reboots the programm will tell you that you need to wait like 20 min. And then it should be up and running again
