[Q] Custom Roms freeze when booting after flash

Hi All,
Seem to have a slight problem with flashing Custom Roms onto my GNex at the moment. Not too sure what's causing it to freeze when booting up. All I get is the X logo and will stay there until the battery dies.
I'm able to revert back to a Google rom and regain use of my phone. Just can't seem to flash any custom roms at all. It's happened with CM10.1, CM10, XenonHD Stable-2.0, Minoco.
I've attempted to flash with CWM and TWRP. Both get the same results. Prior to flashing I've whiped both the Cache and Davlik.
I have previously used CM9 and older versions of Minoco on this device. So seems odd that this is happening now.
Any advise or ideas towards what I should look at would be appreciated.
Thanks,
Drav

you have wipe data before flashing different roms... dirty flashing(only wipe cahce and dalvik) is only if you are updating the same rom.. this is how i normally flash ALL roms
1. wipe data/factory reset
2. wipe system
3. wipe cache
4. wipe dalvik cache
5. flash rom
6. flash gapps
7. reboot
8. wait 10 mins then do another reboot
9. enjoy
PS- the 10 min wait and reboot is soemthing i do that IMO lets the new rom settle

Thanks k786,
It's booted up in a custom rom now after following those step by step. Much appreciated! :good:
Cheers,
Drav

[Q] optimus nexus me v5 [cm7 port] boot loop problem.

since im new to xda i can not post on the main thread http://forum.xda-developers.com/showthread.php?t=2442977&page=12
so i had to create this one as a question, cause i have a problem installing this rom, i downloaded both the kernel and the rom from the main thread, i first flashed to stock rom with odin, then i followed every step to install the kernel and after the rom, but im stuck in boot loop and im kinda angry cause it seems like im the only one with that problem.
i tried to install the rom using white's 1.33 kernel instead of percy's kernel ( the one provided in the main thread) and then flashing the rom, and it kinda worked, because i didnt go in to boot loop, but neither wifi or bluetooth werent working.
pls help me!!! i really want to try this rom!

1.first flash stock ddlk2
2.download the rom and flash it after :
(i) formatting system,data and cache
(ii) mounting all partitions
When done flashing,wipe data and reboot

[Q] HELP. HTC One X Stuck in bootloop. Almost all famous solutions tried out

So I wanted to go to Lollipop and I happened to flash the twrp recovery for new layout(as i was getting boot loop when flashing the rom with cwm recovery)
The things i tried until now.
1. Installed twrp and formatted it to get the new layout. Wiped everything, system, cache, data, dalvik cache
2. It was supporting MTP so i transferred the roms to the device being in recovery. Installed CM 12 + gapps for lollipop.
3. Rebooted to bootloader again. flashed boot.img, and did fastboot erase cache.
4. Rebooted again and stuck at CM boot logo.
I wiped the cache, dalvik cache(actually did a factory reset in the twrp recovery) and tried installing Resurrection Remix. Again flashed the relevant boot.img too. But the same result..
Did i destroy my phone?

Yes I can enter recovery. But again I just cant get any lollipop ROM's working. I dont know whether i have to restore to kitkat(i really dont want too..
I dont get it.. Wipe dalvik cache, cache, data and then disable mtp and then enable mtp.. I mean at the end what does this do?
And in the meanwhile did you mean HTC Sync Manager for device manager. FYI I use a mac(if this helps to get into the problem). And i had flashed kitkat roms from the same without a hiccup but lollipop is failing

Have you solve the bootloop issue? I am having the same problem on my International One X
thanks

Probably both of you encountered the same problem as me.
If you are S-on, you have to flash rom and kernel separately. Also, if you try to revert any changes with twrp you have to flash kernel you were using during creation of backup, and then restore backup.
In other words: your current kernel is incompatible with rom.

Mwys
Yes i am S-ON. Can you tell me what the steps are to flash the kernel? I do not have a backup.
What is did was flash New Layout TWRP, did a complete wipe, then copied the ROM and G-Apps zips to the phone, installed them and then flashed boot.img.
Thanks for the help

Yup I also tried the same. but no luck. I tried to revert back to kitkat(by installing cwm, format the storage, sideloaded the ROM and gapps, flashed the boot.img) and still again in bootloop.
Sorry for the delay. I was a lot too busy with work.

No Custom ROM? Help!

My Xperia ZL won't allow me to install a custom ROM.
Here are the steps I've taken.
1. Updated to 10.6.... (Lollipop fw) via Flashtool
2. Boots correctly, everything seems to work.
3. Flashed boot.img from Paranoid Android and went into TWRP to flash the ROM zip (wiped cache, system and data before).
Did step 3 to test the same for OmniRom too.
4. Phone boots, shows Bootanimation, shows Optimizing apps, then hangs after finish and does step 4 again.
Please help me, I could install custom ROMs on the device before, suddenly it does not work anymore.
Note: EVERYTHING works fine with Stock. Flashed stock ftf multiple times and tried these steps.
Thanks for your help

It seems to be a Bootloop. Try below steps;
1. Through TWRP wipe (system+cache+dalvic cache+data+android secure)
2. Install ROM.zip
3. Wipe cache+dalvic cache+data
4. Reboot
Hope the above steps helps you
Regards,
hitman-xda

@hitman-xda I've tried these steps, except for android secure.
What is that partition and what does it do?
Cannot find it in Advanced Wipe of TWRP.
Thanks

It is the mysterious part. Actually no one knows about it. Some says, it contains secured links/data of some apps.
If you are clean flashing ROM, that's means you have to wipe everything except storage part. That's the reason I mentioned it.
If you can't find it, just leave it

@hitman-xda So I've already done what you suggested, with no luck.
Guess I'm stuck on stock till someone helps me
Thanks for your reply

did you install de correct kernel?
maybe you should wipe everything, install the correct kernel and after that, install the custom ROM
i don't now if it will work, but at least try

I did fastboot flash boot boot.img (got it from ROM zip)
Then erased everything and flashed ROM.
No luck

Does that Paranoid Android was built for your phone?
Your phone loops from 'optimizing apps' , that means your phone is unable to load dalvic/art for the apps.
Also check weather PA ROM can be flashed over lollipop, if not then you have to downgrade an then try the same procedure.
Also you can download stock kernel with recovery, flash it and then directly try to flash your respective ROM.
Usually ROM.zip contains kernel and get flashed during installation of zip, just the thing is they can be flashable over some selective android versions.

Need help to install custom rom

Hello,
I don't know why my lg g3 phone doesn't want boot on custom rom.
I have the LG G3 d855 model, 16gb memory and here are my procedure to install every custom rom :
1. Flash Stock ROM using LGUP (the version of the firmware is not important but the possibility to root is)
2. Install KingRoot and get root
3. Install AutoREC and enter to the recovery
8. Flash Recovery TWRP 3.1.0-2
9. Reboot to the new recovery
10. ADVANCED WIPE (wipe cache, dalvik cache, data and SYSTEM)
11. Flash baseband 21C
12. Flash CUSTOM rom
13. Wipe cache and dalvik cache
14. Flash Gapp
15. Wipe cache and dalvik cache
16. Reboot
I think I did nothing bad...
but the phone does not start and it stays at the initial logo screen (not the LG logo, but the custom rom logo). I waited over 10 minutes to boot but nothing. Even though I install the identical rom again or install an anoter rom, each time the same issue.
This happens with all custom rom (xenonhd, resurrection remix, and now lineageOS)
I can use and boot on stock rom but each time I want to install a custom rom, my phone doesn't want to boot. The phone display stays at the initial rom logo screen.
It seems that I am alone to have this problem.
I don't know why and I search everywhere to find out the solution...
PS : My phone never restart by itself. I never have bootloop with my phone when I using stock rom and same with custom rom..
The problem is the boot with a custom rom. The phone don't want to boot and stay on logo loading...
Any suggestion may be help.
Thank you.

1. Once you installed TWRP you don't have to go back to stock to switch roms. From then on you can just download zips and flash them.
2. You need to delete everything (including system) except internal and external storage ( so you can still flash the zip for xceed, otherwise you will delete it). Remember that you will lose all your apps including your data with it. You can backup them with titanium backup tho. Pictures and video's will still be there as they are stored on the internal or external storage.
3. You also need to flash the GAPPS package after flashing rom, for xceed (7.1.1), pick nano (ARM)
4. Wipe cache and dalvik after flashing and reboot.
5. Make a backup before you do so !!!!!!
Good luck.

Hello,
1. I think that but with specific rom, some people tell us to flash stock rom before flashing a custom rom. eMMC bug related ?
2. Deleting the system changes nothing because the system is wiped when I flash the rom, right ?
3. if the rom boot first then I will install Gapps. Else, I don’t install because the rom doesn’t want to boot.

1. Well .. I've been switching between fulmics,xceed,rr, .. etc without any problem so no, there is no need to go back to stock everytime.
2. Try it, you won't be able to boot until you flash a new rom, but it could help. That's why you take a backup in the first place. It is more 'clean' and if you don't try it you won't know.
3. Sometimes you have to flash gapps directly after the rom or you will be in for a bad time if you do afterwards.
Once you have TWRP recovery installed it's the easiest thing ever to flash a new rom. Make sure your zip files are downloaded okay. Download the MD3 to check it. Try to download via MEGA app or so, because browsers downloads tend to have errors sometimes.
Apart from that. Don't root via kingroot. They have had some suspicious cases where malware was installed on the phone when rooting.
If nothing's works. Go back to full stock through KDZ, root wit your PC, install TWRP via autorec, go to recovery, wipe everything, install modem 21C, install rom and gapps, wipe cache, reboot. Don't try anything other than that.

I have the same problem

Hello,
I have a question.
Can you give me a gapp 100% compatible with all custom rom with android 7.1.2, because i think opengapp are not reliable. Maybe the gapp will cause my issue and the rom won't boot.
Can i use this one https://forum.xda-developers.com/on...isited-slim-gapps-6-0-7-0-unofficial-t3462088 ?
I always use PICO version of gapp
Thank
