[Q] HELP flashing kernel PLEASE

I have just recently begun modding my G2x. I can install ROMs without any problems but I've since been interested in flashing a custom kernel. Information is sort of everywhere and what I do manage to find I am worried about it being out-of-date. Anyway, I flashed cm7.1 (the stable release) and it worked fine until it started fc-ing everything google related (something to do with sync?). I decided to try flashing kernels (wiping caches as instructed) and could never get one to work. I've since flashed the latest cm nightly (201 I think) and tried trinity with it. Still nothing. I've since read that I should let the phone sit for 10-20 minutes but after about 20 minutes it is just a black screen and nothing ever happens. It does get really hot however. Anyway I have tried flashing kernels multiple times and nothing has ever worked, same story every time. Any way somebody could tell me what I'm doing wrong? Tell me what's compatible (as maybe sorta stable) with the ROMs I'm using? HAHA and if it's not asking too much...maybe some links too? Sorry, just very new to this and very eager to learn. I just have a bit of trouble figuring out what's supposed to be compatible and where to find it. THANKS!

Start over fresh, wipe data x 2, wipe system x 2, wipe cache, wipe dalvik cache, flash cm7 nightly, dont reboot yet, wipe cache ONLY, wipe dalvik cache ONLY, flash kernel try faux123 (make sure kernel is for cm7) latest or morfic latest, reboot, enjoy ....

Thanks will give it a shot in the morning. Too much of a headache all day. Back in a useable state and I want to keep it that way for a bit haha. Will post results.

I still haven't tried to flash a new kernel... that is coming in a bit. I do have a question though... I'm interested in getting my phone in the cleanest state possible before doing anything further. I basically want my external sd cleaned up (I want to just reformat it) before flashing a rom again. What files/directories are absolutely essential to keep? As I said, I want to just wipe it clean but I'm not sure I can do that.

So just to be thorough I can safely remove the cwm directory as well? Just delete it all put my rom and kernel zips back and I'm good?

Make sure you flashed recovery through nvflash

Tried to just flash 0.4.7 and it did the same thing as before. Waited 20 minutes before taking out the battery then tried to boot it again. Waited 20 more minutes and all it ever did both times was get hot. Same results as before.

(Q) One Last Grasp: The Lose Data, Lose APN CM code bug

After reading thread upon thread and flashing rom upon rom, wiping and nullifying the way along. I still have this issue that many of you are aware and just hoping by chance I may have missed the answer and someone can help me.
I am experiencing the bug where if you lose data, whether it be by switching to airplane mode and back, shutting of the phone, not rebooting it, or just a drop in coverage, when it comes back the APN list is cleared and can no longer connect to any data. Calls and texts seem to go through, but surfing and picture messaging don't work until the phone is rebooted, normally or through the button combo.
I've tried wiping everything several times, even uses the nullifier dual wipe twice and it still happens. I've tried all kinds of roms, 2 different MIUI, Eaglesblood, Kang Banger, Weapon, they all do the same thing. The only thing that "works" is restoring my very first stock nandroid. But once I go from that, wipe, and flash another, the problem returns. If it matters, my order of rom flashing was stock then Singh MIUI-GalNet MIUI-Kang Banger-EaglesBlood-Weapon-Singh. All gingerbread roms (I believe).
So if anyone can offer me just the slightest of solutions, it will be so very much appreciated. Thanks in advance.

When you saying "wiping"...what exactly are you wiping?

I've worked pm with him, he's wiping system, cacheS, data, flashes zips then boots and then reboots later and fixes permissions. He still gets data drops and loss of apn's.

Yeah mt3g has been a real help, but we're stumped. I wipe the data, wipe the cache, wipe the davlik cache, format the data cache and system, flashed, wait 20 minutes, reboot and fix permissions, reboot and wait again. Even flashed different kernels. All to no avail. And for some odd reason, I use T-Mobile, but I have Simple in my APN list as well and I think that leads to the issue.

I noticed Harsh's latest Kernel fixed the issue for me.

Why are you bringing up a kernel that is for cm9 when the discussion is about cm7?

Yeah, that would cause a whole new set of problems huh? lol

Dalvik and cache wiping in TWRP.

Does anyone know why it takes so long for TWRP to wipe the dalvik and cache? Is it because of the new ART? What used to take only a few seconds now takes at least five minutes and sometimes I wonder if it's frozen up.

Your not using the latest version. Use 2.6.3.4

Are you updated to the latest twrp? Mine doesn't take that long. Longer than it did on my GNEX, but not five minutes

I used to have this issue, would take up to 10 minutes to wipe cache and dalvik.
However it's been fixed now, not sure if it's the TWRP update, or the 4.4.1 update, but between them it now only takes a few seconds.

Latest 2.6.3.4 fixed that issue.

Downloaded latest TWRP. Problem solved. Thanks

Thanks for this thread. I was literally about to ask the same question. I'm glad to see this has been fixed. Sitting around for five minutes seemed a bit insane for wiping cache.

Cataclysm Rom - Home Button/Toggles not working

Hello everyone. So I have now downloaded the cataclysm ROM Latest build for Hammerhead, and I verified the md5 checksum, flashed it in TWRP, it boots up and everything seems to work great besides the home button (makes a click noise and indicates it is indeed accepting the touch, but nothing happens), and the quick toggles. I press the button on the notification bar and nothing happens, I can't even access the screen.
I've seen other people have had this problem but it has gone unanswered, or has been related to a broken download.
But I have downloaded the ROM 5 times from 3 providers, one with multiple mirrors, on different devices too. Checked the md5 of the last 4, they matched exact, but I still experience this issue sadly.
Any thoughts on where I should go from here?

Did you do a full wipe before flashing the rom?
Sent from my Nexus 5

Yes, but only the last time. Let me try this again and ill post back an update.

Wow I'm officially an idiot.
So used to having an SD Card and using ClockWorkMod Recovery that I just wiped all my data. Literally everything including my backups.. I'm such a fool.
But anyway, went to the bootloader got into recovery and flashed the Cataclysm ROM from an SD card with a Meenvo USB OTG adapter. Luckily I had it. And luckily I had a million copy's of the ROM.
So yes I can now say that a full wipe worked. Lol. Wow.
Thanks JD.

Lol, a full wipe is system, data, and the caches. Not the whole device. But glad it's working for you now.

Reboot frequently and data/setting lost

My phone is meeting a issue of high frequently reboot, and when after reboot, some app lost it's data, and some system settings are restored, such as wifi password lost.
I tried going back to stock rom, but this issue still happens.
So, can anyone who knows what is wrong with my phone?

Sounds like a corruption during flashing of the ROM. Try wiping all data/cache and Dalvic cache, and flash again.

I have tried several ROMs included Stock ROM, it all happens so...
I think it has no relation with ROM.

If it's happening on all roms, including stock, it's most likely a hardware issue. I'd warranty the device
