Flashing JB Roms causes bootloops

Hello guys!
As the title says, I keep on having boot loops after flashing any custom JB Roms (Jedi, LiquidSmooth, CM Nightly, Slimbean). I'm not new to flashing roms (I got LG units though, SU660 and KU5900). When I tried flashing ICS Roms, I don't have any problem. But I want JB that bad!
I followed KonstantinKeller's thread of restoring/recovering from a bad flash (going back to GB), rooted following Melvin's thread. Then did all the prerequisites..like the common wiping of data, clear cache & davlik. But then again after flashing JB roms listed above, I keep on having boot loops!
What did I do wrong? This ain't my first time flashing (first time on this phone -T989- though)
I read some posts with almost the same problem, but I don't think I found a solution for this. Any good soul that can extend their help is highly appreciated. Thank you in advance.

I got a bootloop before when trying to flash JB roms and what I did was restore to original state (using the bad flash recovery technique), and then not rooting it but installing cwm through Odin and dirty flashing the Rom in cwm. Once it flashed I used it for a few to make sure that everything was working correctly. Then I got the goo manager app and got twrp. After that I followed all the steps in the OP (Jedi jelly) and flashed the Rom. Now I'm running Jedi jelly 3.1 perfectly. Hope this method helps.

are you using darkside scripts to wipe? because they will cause bootloops

is there any way to reverse the loop that the darkside wipe is causing?

it REALLY sounds like the recovery u are using is TOO OLD. Make sure u are using the latest version of twrp (2.3.3) to flash all jellybean roms.
TWRP is backwards compatible and touch capable, so if you're worried about flashing GB or ICS ROMs it'll do the trick just fine
it is however a requirement for flashing all 4.1 ROMs.
Basic install instructions:
make sure u have root
download goo manager from play
open > menu > install open script recovery
agree to everything, but make sure t989 is in the downloaded image name
reboot to recovery u should see twrp

Help me move from ZVB stock rooted (adriVelasquez) to a 4.2.2 rom

Hey all I'm pretty noob with the flashing and wondering if someone can help me move from the ics stock zvb to something 4.2.2
I'm looking for something stable with minimal bugs and no showstopper bugs to use as a daily driver. I want something I can keep a while without reflashing.
All help and handholding appreciated.
I really don't know what steps I have to take and in what order...
Do I have to reflash the radio again?
Thanks

To jump on the 4.2.2 bandwagon you will need to do all of these steps and depending on the actual ROM might take more really read the installation steps before trying anything and definitely make a backup of your current configuration
Make sure you are on the jb ota (android os 4.1.2) or used the appropriate teeny bin
Must be unlocked ( using freegee... available in the market ), rooted, and using team win recovery (twrp)
Make sure ROM and gapps are on your sdcard
Reboot into recovery
Factory reset
Wipe system (not data/media)
Wipe cache and dalvick cache
Flash ROM
Flash gapps
Then reboot and set everything up

I didn't get the OTA update, I updated via flash to the zvb stock JB using freegee goomanager and twrp. So do I need the zv9 or zvb teenybin? That's one thing confusing me.
Or should I revert back to stock ICS, then do ota to JB then do Freegee again and flash to 4.2.2?
Aftyer all this, my next phone is going to be a Nexus.

Okay I got my phone restored back to stock zv8 ota updated to sv9 then zvb
Next I saved a bunch of backups both efs and twrp
Then I flashed my new rom, The very lovely Revolt JB. and after clearing cache and wiping it booted...but....I forgot Gapps...:silly:
Question:
can I flash it over the existing install or do I need to reflash both the rom and Gapps at the same time?
Thanks and cheers

just drop gapps in storage and flash it in recovery you dont need to flash rom again

[Q] How do I update my rooted Nexus 7?

Hey guys I just got the Nexus 7 2013(Wifi) today for Christmas and I just rooted it with Nexus Root Toolkit, and I wanted to know how I can update to Android 5.0 without wiping it. I have Android 4.4.4 with the latest TWRP.

You didn't install a custom ROM? I have the same tablet, I also rooted mine. I updated to Jellybean and everything seems to be working, except I lost root and it's really annoying that I haven't found how to root it again without it being wiped erasing all my apps and data.

You can update it via OTA, but you will lose root.

If u are only on jellybean, u might be able to just use the towelroot apk and not erase any data...

You can either:
(1) Wait for the OTA: hence no wipe of data
(2) Use the factory image and remove the wipe command (-w) (search for a how to, answered many times here)
(3) Use the OTA zip (not familiar with process, if it wipes or not, as I always use factory images but I guess there is a how-to in here as well somewhere!)
(4) ...
One thing you should take into account though is that for a major android version jump (e.g. 4.4.4 => 5) you should always consider to wipe.
In addition, questions go into Q&A section

You can install multirom. So you can keep the stock rom and install lollipop as well. Just have a look at the multirom thread on how to install it. It's quite easy.

There is zero reason not to do a clean install in your situation.
Flash the factory image, reflash twrp, flash su zip, done.

You just got it so why not take the wipe and just install the image from google?

[Solved]Nexus won't boot after ROM and other things

Hello guys, I've searched a little and didn't find any posts that could help me specifically for the Galaxy Nexus.
I've flashed my phone a long time ago and have been using Paranoid Android for probably over a year.
The problem is, my cellphone was really really slow. So I decided to try a new ROM and re-flash it. And So I did.
I've tried flashing this Full_Auto R11 kernel then the CyanogenMod 12 and finally GAPPS.
I was getting error status 6 on Clockwork mod on gapps, but eventually got around it. But it didn't install play store, I've tried manually adding but it didn't work.
So I went for another 5.0 ROM (I'm really interested in getting android 5.0). Wiped all the data, all the cache, installed everything and rebooted.
Bam! Infinite booting screen.
No, I didn't create a nandroid backup because I'm really dumb.
So, I need your help. What I want to do is to get my phone working again with a 5.0 ROM (if possible).
I can boot into ClockWork Recovery just fine, if that helps.
Thank you for the attention.

I would recommend to install latest full factory package from Google.
Then you will start with everything stock, so flash latest TWRP recovery via fastboot (CWM is no longer supported, so error 6 when installing new Lollipop Google Apps appears).
Then in TWRP, do a factory reset, wipe /cache and /system partitions.
Then you can install your Lollipop ROM (over ADB or by pushing ROM package to emulated sdcard).
After this, install latest Full_Auto kernel.
At the end, install Pico Google Apps.
You must install the Pico version, because our /system parition is too small to handle Lollipop with all Google Apps included.
This should work for you, and you will have fully working Lollipop on your Galaxy Nexus
P.S: If you intall the AOSP Lollipop ROM by @freshgiammi and you miss root access, install latest SuperSU flashable zip.

Thank you!
Thank you man!
I've ran into some troubles but managed to do everythings correctly =)

Thanks again for the reply, LamarrCZ!!

Trouble Flashing Custom ROM

So I rooted my 5X with the help of the Nexus root toolkit. I have successfully flashed Elementalx kernel through TWRP and have tried flashing the ROM and GApps through the toolkit and through TWP but always end up in a bootloop at the Google screen. What am I doing wrong?
I'm just looking to load a Custom ROM to possibly squeeze some extra battery life out of my 5X.

Bootloop
Hi mate,
Did you try and clear cache & dalvic after installing the rom through TWRP.
Also did you install the kernel after the rom & gapps, also try another kernel maybe, or use the stock one with the rom ( if possble ).
or grab the factory image and go back to stock & lock the bootloader.
Also, I did read if you do not use the SDK toolkit from Google ( contains Fastboot and ADB ) , you can have issues like this.
http://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930
I will do some reading and see what else I find.
Later

Which ROM are you flashing? Most have a decent installation instruction you should follow precisely.
Basic steps in correct order:
Download ROM and Gapps.
Clear data and caches (always clean install a new ROM).
Flash ROM
Flash Gapps
Flash custom kernel
Root.
Boot (on pre 7.0 first boot may take 10+ minutes)

I chose options to clear cache and dalvik when using the Nexus root toolkit and then again manually when I tried to flash through TWRP. I don't quite remember which order I tried to install the kernel. I'm assuming from your question the kernel always always has to be flashed after flashing a ROM? (Even if the kernel was previously flashed?)
I'l look into doing it the 'old fashioned' way as it seems it should iron out any issues. Thanks for the help and please reply if you have a chance!

I'm attempting to flash the latest version of Pure Nexus, Gapps, and Elementalx. From what little research I've done it seems like people are able to run this ROM and kernel combination without issues.
I followed these steps to a T and cleared cache/dalvik after every flash. I am on Nougat right now and the phone would get as far as the Google bot logo. The longest I waited was probably 10-15 minutes. Could it possibly take longer on Nougat? Does that have anything to do with encryption?
Thanks all!

It's unclear to me if you did a clean flash or not.
Check out post #2 in the pure Nexus thread for detailed installation instructions. Follow them to the letter and you should be fine.
I've been running pure Nexus with elementalX for some time now and never had any problems. Are you sure you aren't using the nougat version of elementalX? 3.05 is NOT the correct version for running pure Nexus at this moment as the ROM is still based on 6.01.

THAT must be the problem! I didn't know it was running on Marshmallow. I'll give that a try now. Thanks for the obvious answer!

So not only did I need the Marshmallow version of ElementalX but I also needed to update my vendor image for the PN ROM. Thanks for the help! All set from here on out.

Glad to be of help. Have fun with your phone!

First of all make sure you're on the correct firmware for whatever rom and kernel your wanting to use or it will not boot. It will bootloop if on say a Marshmallow build amd your trying to install a Nougat rom.. Now if all matches you can proceed.. This is how I've installed roms for 5-6 years: in twrp wipe: data, system, cache, delvik cache, flash rom, flash gapps (open gapps mini is what I use) flash either SuperSu zip or PHH superuser, next reboot. Some roms (example: DU and AICP) come with SU already inside so no need to flash it.. You can tell because in twrp during flash process you'll see SU being installed If rom comes with it. If you choose to use PHH Superuser you'll need his app from Google play store. Just grab it (search PHH Superuser) and open it and you should be good to go. I use SuperSU as I've had issues using other SU with ARISE sound which is also something i use. Hope that's not confusing.

Hi mate, i have now unlocked bootloader, installed twrp and installed pure nexus rom. Did not use the toolkit, i used adb and fastboot using commands... It was easy.
