sm-g7102 - Galaxy Grand 2 Q&A, Help & Troubleshooting

Hi guys. I just want to ask how to fix bootloop. I think its bootloop. I flash stock ROM from Samsung. Then I tried to flash custom ROM( already done this numerous times in the same phone(cm13, RR, aokp) before I flash stock rom) but when the flashing completed and the phone reboots, its stuck in boot animation. Right now I'm trying to flash this aokp 7.1 for sm-g7102 but stuck in boot animation like other custom ROM. I've already installed aokp 7.1 , cm13, and RR on this phone before I flash custom ROM. Pls help me flash at least aokp. I'm stuck at 4.4.2 KitKat. Help me guys.

[Q] Can't flash any ROM - help?

Hi there.
I have a Samsung Galaxy S4 GT-I9505 and I’m using TWRP Recovery 6.0.4.4.
I tried to flash a nightly-version of CyanogenMod (cm-10.2-20131101-NIGHTLY-jfltexx.zip). I did a Factory Reset before flashing, TWRP said it had been successful.
When I tried to boot my phone, I can see the "SAMSUNG GALAXY S4 GT-I9505" logo, here it got stuck. I can not see the cyanogen boot animation.
Though MD5 hashes and file sizes are ok, I tried another ROM: SuperNexus http://forum.xda-developers.com/showthread.php?t=2407616
Here it was exactly the same. My device gets stuck even before the boot animation.
I was so desperate, that I tried to format my complete internal storage. Flashing the ROMs was successful again, I could boot both ROMs CM and Supernexus then. But after I turned off my device I can't boot any more. Again I can not see the boot animation.
I have already tried it with PhilZ and CWM. I flashed them using my current recovery.
Any advice?
I am sorry for my English, if you need more detailed explanation, please ask. I tried to describe everything as detailed as I can.
Can you get into download mode? You may have to flash a stock ROM to get it to working again. Was the phone previously rooted?
And are you currently on a stock ROM or coming from a custom ROM?
Yeah, I can get into Download mode.
Well, I am not sure what ROM I'm currently using since I wiped everything. Previously I had FoxHound ROM, samsung-based pre-rooted custom ROM.
Have you tried flashing a custom Kernel?
Sounds like what I had when I tried to flash a TW Kernel for a AOSP ROM.
If you can't get into recovery, go into download mode and flash the latest CWM. Got my phone working.
FoxHound ROM installed a custom Kernel, "Ausdim Kernel" I think.
Now I have CWM 6.0.3.2 from here: http://forum.xda-developers.com/showthread.php?t=2279579
Not sure if this is the latest version ... I can't find an Odin-flashable *.tar
Anyway it doesn't work too. This recovery can't even flash CM, it gets stuck at "opening update package ..."
Sorry its a bit late.

Use them. This may help as a tutorial to follow loosely but that was for non working WiFi.

I am having EXACTLY the same problem here!!! It happened after I flashed stock BTU (UK unbranded) and then trying to revert back to BlissPop/CM13. Maybe the new stock boot/modem is not supported by custom ROM makers yet?
Could anyone confirm/solve this? Thanks a lot!

Just verifing. When flashing a new rom, you are clearing the old one out first, right?
Like wiping the cache, system, boot,ect.

(I'm #2) Did all the usual wipes. No problem with stock rom, but cannot boot after flashing any custom ROMs like CM13.

Sorry its taken me so long to reply back, had stuff going on. Anyways, after doing some studying and playing with my sisters G5. They seem to be very finicky with modifications, even after root and a custom recovery installed. One thing to try (because it happened on my skyrocket), is to reinstall your recoveries and do it with a computer, that how to get a stable install, if your already using a computer, then it sounds like a something from the old firmware may still be their. You may need to install the earliest stock firmware for your G5 out of the box, and root it from their, you may even need a complete stock restore then re-root and install your custom recovery. Also. I have had some roms take 20 minutes to boot, but thats the rom stabilising.

What's the version of TWRP?
First try to update to COS12 stock ROM and check if its booting normally. Afterwards try to flash custom ROMs from latest TWRP recovery.
Yes I thought that only to flash it on COS 12 but if another solution is available to direct update it to CM 13
And I m using Latest version of Twrp recovery

You have tried everything but nothing worked. So I think flashing official COS12 first is only option left now.

Phone keep bootlooping after flashing new ROM

All the CM Based ROM cannot boot, but the stock cm(13/14.1) can work

I haven't unlock my phone yet. I used the qpst tool to flashed the rom to zui 0.9. Then I flashed the offical twrp.
Offical cm13, cm14 and some aosp rom(slim etc.) can boot and work well on my device after flashing, but cm based rom such as nuclearom and bliss cannot boot. They always stuck on the boot screen and fail to boot into desktop after a clear flashing. Have I missed something?
You have to unlock bootloader and do clean flash otherwise you may encounter such problems with custom roms
