Hey all, so I've got a nice little nexus 7 that I'm trying to turn into a head unit for my car, but I don't seem to be able to flash any other roms.
I got off the stock rom almost as soon as I got the tablet, unlocked bootloader, converted to f2fs, and flashed Xenon HD with 5.0.2. After that, I didn't really touch it much until now, and all I get when I try to flash other roms is a bootloop and I'm hoping someone can help me out. I initially started with USB ROM and Timur's kernel, but that just stuck me at the boot screen so I went to try Autodroid 1.2. Very surprisingly, that was a bootloop too. Getting somewhat worried, I went back and restored my backup which didn't have any problems, and booted straight into the system. Thinking maybe there was just an issue with the these head unit replacement roms for some reason, I tried Optipop and got the same thing, then on a suggestion I saw in the autodroid thread I tried flashing Slimkat since that's what Autodroid is based on, not sure why that would help but I was willing to try anything. And, surprise surprise, still just a bootloop. So now I'm back on my Xenon backup and really quite stumped.
Thanks for your assistance!

Hi all,
I recently installed the newest build of Slimbean. I am having a few issues: I am unable to play any media... Music, videos (youtube). My phone app does not work. I cannot receive nor send any calls. And my phone produces no sounds at all.
I tried installing build 7 to see if it was an issue with the build I was using... didn't help.
Internet and wifi work without any problems.
Galaxy S4 i337m
Baseband: I337MUMUAMDL
Version: Slim-4.2.2.build.7-OFFICIAL
Build #: slim_jfltecan-userdebug 4.2.2 JDQ39E eng.blk_jack.20130706.15730 test-keys
Any ideas?
Thanks in advance
Update: Any ROM I install... Phone and sounds do not work.

I'd Odin back to stock and see if you still have the issue. If you do it's a hardware issue.

I did just that... But it's a bit of a story.
I had just fixed another problem I was having yesterday. Was getting stuck at the S4 splash screen right after powering on the phone. The problem was caused by TWRP 2.6 and formatting /data partition. Long story short, I installed CWM and used it to do a full wipe/format of partitions and then was able to install ROMs, restore backups without issue.
So today, since everything was working, I decided to flash a new custom ROM (which I installed) and the MG1 radio. Wasn't having any luck with the radio. Finally, I was able to flash a radio via mobile odin, but then I soft bricked my phone. Got stuck at the S4 splash screen (same issue I had yesterday, but this time, a different cause). So was troubleshooting it all day. Tried to go back to stock, no luck. Tried to restore the stock backup I had, no luck. Only thing I could do was install custom ROMs at this point to get into my phone (i.e. Slimbean, FoxHound, etc...). But, at this point, although I could boot into Android, I had no sound at all and couldn't play video. So after hours of trial and error, I installed CWM again (replacing TWRP 2.5.0.2), did a full wipe/format and tried to install a stock ROM. No luck. Still was hanging at the S4 splash screen. Then I tried to install this ROM again which I had luck with in the past; |ROM| |★VLUAMG1★| |CANADIAN||i337M||STOCK||ROOTED||July.26.13|. But his instructions said to install a wifi fix or fear soft bricking my phone. So I installed the wifi fix, but selected the wrong file (I know, stupid. Done a lot of stupid **** in the past couple days with this phone). Now, after the phone rebooted, I would see the S4 splash screen for a split second, and it would auto load into download (odin) mode. Couldn't get into recovery at all. So then I decided to flash one of the stock ROMs I tried earlier that didn't work, but this time, SUCCESS!!!!! Phone was booting and all sounds worked. I could make/receive phone calls as well... Everything seems to be working fine now. I find it funny that flashing a wifi fix that I shouldn't have seems to have fixed my issue in a sense. Since it allowed me to successfully flash a stock ROM. So I am making a backup of the stock ROM and will decide what I'm going to do from here.
Holy goalie!!! It's been a very vexing couple of days.
Nice that you got it all worked out, I've found out that if your "status" is custom, it will sometimes give you problems when flashing a "stock" rom via odin.
So what I always do when reverting back to the stock rom, I use triangle away to clear the flash count and make my phone back to "Official". If you want the steps to do this, let me know, it's not hard, but there are crucial steps to get this right!

Guys, running out of ideas, maybe someone can think of something else to try before I give up and go to Asus for repair (should be under warranty but was bought on ebay).
Grouper 32 GB was working fine when I bought it. Immediately flashed USB ROM (Timur's kernel), as the whole plan was to install the tablet in a car. Used CWM 6.0.3.6, wiped appropiately.
Tablet would freeze during boot, if lucky a few minutes after booting. Tried several wipes with no difference.
Reflashed, same thing.
Also tried CM 10.1 with included kernel, also with Timur Kernel. Then went back completely to factory 4.1.2, same thing. Installed TWRM and tried all roms again, and Atom 4.2.2 with included kernel.
Now went back to factory 4.3 including bootloader 4.23, same thing.
No dirty flashes anywhere, don't know what else to wipe.
Here's a last_kmsg but I don't really know what to look for: pastebin com 7TCyj5X7
I appreciate any ideas!
Thanks
I have scoured the internet to find someone with the same issue as me, and I haven't found enough to fix the issue, so I'm placing a plea for help here. I have installed TWRP 2.6 recovery, and I am trying to flash OmniRom 4.4.2 nightlies. Originially I was trying to flash cyanogenmod 11, but I had this same problem. It appears to be any kit kat rom that causes the problem (I haven't tried flashing stock or any non-kitkat roms, but I was running on rooted stock before I tried to flash CM11). Anyways, When I flash I am wiping dalvik, cached, system, and data. Then flashing the rom, then flashing Paranoid android gapps. It will boot the first time fine. My phone will work just fine afterwards. However, if my battery dies or I restart, I will be unable to boot back into the rom and my phone becomes a soft brick. It will just stay stuck at the galaxy s 4 logo for as long as I leave it on. I have left it on for more than 30 minutes and there are no changes. I can't have my phone being just a dead battery away from being bricked, so I am asking for your help! Anything is much appreciated!
One other side note: I had my phone just lock up on me once in the middle of it running just fine. Afterwards it turned off on its own and tried to restart, but it resulted in the same issue. I don't know if this is related or just a bug in the rom.

Omni clearly states that it is an alpha, so you mileage may vary considerably.
Sounds kernel related. Have you tried just reflashing the kernel and seeing if it'll boot after that. Or trying a different kernel?
Thanks for the reply! I actually just fixed the problem on my own. I used Odin to flash a newer version of TWRP and then flashed omni, and it looks like everything is working just fine. I read a few people saying that they were having issues flashing kit kat roms with older versions of recovery, so I figured it was worth a shot.
So I have been running CM11 since January and finally got around to updating to KitKat to see what was new and because CM11 wasn't using the kitkat kernel which I assume is what caused all the SoDs and instabilities in all the ROMs. Well now I'm on stock and I'm suffering horrible battery life in comparison (17 hours with 4 screen on vs 36 hours with 8 screen on). I tried flashing CM11 and it worked but after a day or two I wanted to try a new ROM. Carbon was one that I saw near the top of one of the G2 development forums so I decided to try that. Went through the normal process to flash a ROM and it bootlooped when I rebooted. My backup also boot looped and I had to use some method to go back to 12B since I had no ROM or anything on my phone. Got back to 24A and I tried flashing Malladus to see if a stock based ROM would work and it looped. Restored my backup and tried CM11 and it also looped. Now I'm sitting on stock with Verizon's bloat hogging resources and battery and a phone that won't flash and boot successfully. Is there any way I can fix this? Has anyone seen this before?
TLDR: phone won't flash a ROM without bootlooping since 24A update
Only gonna bump this once but I really hope the right person sees this. Really confused as to why my phone won't properly boot after a clean ROM flash
Hi all,
I recently purchased a 2012 wifi Nexus 7 to install in my car. I've flashed a couple Roms successfully, but when ever I try flashing the USB rom it is stuck on boot screen. I've left it alone for 30 minutes and it won't change. I'm wiping everything every time I flash the Rom like I do for the other Roms. Is there something I'm missing? Thanks for the help.
