[Solved w/ workaround] Rooted 3G Nexus 7 stuck at boot after 4.3 Jellybean OTA

Hi there,
I have a rooted 3G Nexus 7. I ran the notification to run an OTA update for 4.3 Jellybean, it rebooted into TWRP, and I blindly said yes. Eventually I confirmed TWRP to allow it to fix root permission. I tried rebooting, but I ended up getting stuck at the X screen. Tried a few resets, but that didn't work. I Googled a bit, cleared the cache and the dalvik cache on TWRP, and came across this.
I got lazy, and probably shouldn't have done most of what I had done, so I'd like to know if there is a way to fix this without having to reflash the ROM.

Fix
I got impatient waiting for a response, so I just flashed Cyanogen on it, thinking this would be the most opportune time to try it out hehe. To anyone else who runs into the issue and sees this, I'm 99% sure that you could just flash stock on too, but I wanted to try out a custom ROM.

[Q] - Error when updating to 4.4 - Official

To my delight, I got the OTA update or whatever it is, the official thingie to update to 4.4, icon and all.
I start it up, it goes through the motions, then it gives me a nondescript error (( The little Android looked like how it did when it's awaiting a bootloader instruction. ))
Does this mean my Android stock is borked? Do I need to factory wipe? I am confused. I did, however, download the Google-based Nexus 2012 KitKat build and I attempted to ADB it, and it gave me yet another error, with this - E:Error in /tmp/update.zip.
Any help that can be given would be wonderful.

I have the same issue. I wiped the cache and done a factory reset but it didn't fix the issue. I downloaded Nexus root toolkit as it has a unbrick feature and ran that but it seems to have made it worse, I can no longer get into recovery.

[Q] Build KRT16S?

OTA for KRT16O from JWR66Y failed on my Nexus. It bootlooped, and I had to reflash stock. I haven't yet decided to try updating again, but today I got a notification that an update was ready to install. I checked it out, and the file says (in part) signed-nakasi-KRT16S-from-JWR66Y.
I've searched the Nexus forums for KRT16S and can't find mention of it. Anyone else have it?
What's the difference between that and KRT16O?
Inquiring minds want to know.

Coming from 4.3.1 myself, was running 16O myself for a week+ and then got the OTA for 16S, it's a minor update, bug fixed and newer apps, etc. and seemed to run smoother, and has the GEL, etc. - running quite smoothly for me to the point where I decided to wipe & deep clean and start fresh.
Then, I saw this & decided to flash it instead, keep my CWM & root, but essentially just like factory fresh rom, with SUv1.75 and busybox, odexed and starting off with plenty of internal storage space. Got lazy instead & opted for it instead of flashing image, running ADB & unlock routine all over.

As always, backup via TB & custom recovery, and save it offline to portable storage first, just in case. I was fully prepared this past weekend to start from scratch - too many posts about problems downloading, upgrading, bootlooping and freezing, etc.

[Q] Nexus 4 has a Nexus 7 v2 build number and can't unroot. NEED HELP GETTING STOCK

My nexus 4 was rooted a while back before I got the OTA 4.3 android update via system update. Everything went fine then with that download. I was a bit anxious to get the 4.4 kit kat release and having seen it appear in system update 2 days ago I decided I was gonna download it yesterday and I did. After it finished the phone restarted and then was stuck in an infinite loop. I had no backup and so I decided to wipe; after which I had no operating system. I downloaded the
factory rom image of 4.4 (stock_mako_KRT16S.zip),
radio (cwm-radio-mako-m9615a-cefwmazm-2.0.1700.97.zip)
and bootloader (KK_4-4_BOOTLOADER.zip)
I flashed the radio first then then bootloader and both fine, then when it was turn for the factory rom it said error extracting file.. the dreaded status 7 error.
Anyways, I figured since it wasn't working I'd just go for a custom rom and I had rasbeanjelly on my phone from back when I rooted but never got around to flashing. So I thought I would try it and it flashed along with the gapps 4.3 but I've had several huge glitches such as the phone moving slowly and missing important google apps such as camera and such.
So I was up all night trying to figure out how to go back to stock rom and do a recovery and everything I tried was no luck. Kept running into the status 7 error. Watched a few videos that suggested I get Wug's Nexus Root Toolkit to unroot and then lock my bootloader and then flash a stock recovery. It didn't work because I realised one severe difference.
MY NEXUS 4 HAS A NEXUS 7 BUILD NUMBER.. I googled the internet and nothing..
Anyways. Says android 4.3
Build: JSS15Q
rasbeanjelly build: fri aug 23 2013 (probably old)
I just wanna know how I can get back to stock.
And I lost my root privileges as well when I flashed rasbean.
Any other information can be provided. THANKS MUCH.

[Q] Purchased used Nexus 4 in China, no roms > 4.3 work. 4.3 working only with

I have purchase a great Nexus 4 in China at a 2nd Hnd phone market that worked great for a month or so. I purchased it, it was unlocked and running 4.2, which Through OTA was updated until reaching 4.4.2.
All was well. Everything worked like a dream. Decided I needed root one day, and tried a toolkit. Don’t know how but I wound up in a bootloop/soft brick at the circles.
Factory reset didn’t work. Toolkit original flashing original rom didn’t work.
So, here are the processes I have gone through to get this working.
1) Flashed every rom from the factory rom s listed on googles dev site through fastboot, and also by runing the included bat.
2) Using the newest Android SDK for 64 bit wind 8.1. Have used both the generic driver, pda driver and googles sdk driver.
3) Have sideloaded ota updates from the ota list
4) Have manually used fastboot in every way possible that I know about…
5) Have tried custom > 4.3 roms
6) Have tried twrp & cym
7) Have wiped cache, factory reset, lock/unlock
8) Have tried rebooting in safe mode and removing the -w when flashing system
9) All I can get working is 4.3 when I flash the .54 radio from the JDQ39E rom
So some questions:
1) If the memory on the phone is bad, why do the roms under 4.3 work?
2) Is this an Indian rom?
3) Is this a Korean rom?
4) You can notice there are many different ota versions depending on the rom you are coming from. So I am venturing to say that these roms are not so one for all globally as people think.
5) I always seem to have a korean IME on the phone on a fresh image flash
6) When using the JDQ39E rom, there is an Indian IME
7) I have been unable to find any factory images or rom designations for India or Korea,
8) I did find a thread on here where someone created a cwm flashable zip of the JDQ39E rom it works well, but unable to sideload ota > 4.3
I have hammered this topic for 4 days and nights not hardly sleeping. I am out of Ideas. Its real hard to get nexus 4 in China for me and I really liked the phone. I hate being stuck @ 4.3. I would be so greatful If anyone could help me overcome this challenge.
