[Q] Fuzzy TV Screen after flashing wrong Kernel

[rodashtoc]

I have an ATT Captivate that goes into a fuzzy screen after it goes from the initial White ATT World Phone screen. The wrong kernel was flashed on it after I mistakenly read a post trying to upgrade the the Apex rom. If anyone could be of any assistance. I can't get into Download Mode or Recovery mode... but it still turns on. I'll post screenshots if possible.

Ouch, so no download mode or recovery mode? Have you tried booting into download from ADB? if you don't know what adb is then don't worry about it. You might try seeing KIES recognizes it, if not, download any ODIN package and see if the ODIN recognizes it, if it does you're in luck! If not, then you might consider ADB: I'm no expert but I'm sure that when you have ADB there is a way to replace the Kernel Image for a proper one. Just out of curiosity, which kernel did you accidentally flash?

It has nothing to do with kernels, you have a GB ROM with Eclair/Froyo Bootloaders

download mode still works even if it doesnt look like it.. er.. wait download mode should still work. scratch that it WILL still work. flash gingerbread bootloaders

Well

download mode still works even if it doesnt look like it.. er.. wait download mode should still work. scratch that it WILL still work. flash gingerbread bootloaders

The second problem is... it loops after the fuzzy screen. It only stays for 5-10 seconds then goes back to the ATT screen.

I do know what adb is and I've used it a lot especially with my girl's Mytouch 4g. It's just this was a big problem I haven't been able to crack.

I believe the kernel that was flashed was TalonDEV 0.5.1-RC1 from http://forum.xda-developers.com/showpost.php?p=18330648&postcount=5215

Edit: Odin sees it for the 5-10 seconds it's on... but since it's bootlooping... Odin doesn't have time to do anything further than file analysis.

2nd Edit: The battery status comes up when I plug the phone up when it's off... I know that probably doesn't help, but I figure I should give all the information I can.

Its the KERNEL.

If you have froyo bootloaders and a gingerbread ROM, it will still boot into the ROM and work. But on boot, the KERNEL splash screen is that distorted image in the OP, and also recovery is inaccessible because all you get is the distorted image. And as you should know, recovery is contained in the kernel.


If you're on froyo, and flash a gingerbread kernel, not only will you have the issues stated above, but you'll also likely be bootlooping, which is exactly the situation in the op.


OP.. You don't use Odin booted into Android, or in a bootloop. Its used in DOWNLOAD MODE ONLY.

Search for "usb download mode jig" you can make one, our buy one fur under 10 bucks. It'll boot it into dl mode in seconds.
Then go to the top of the development section, find a gingerbread package WITH bootloaders. flash that, THEN proceed with your original plan

Yes or flash gingerbread boot loaders and get recovery back, Then flash and appropriate kernel in cwm.

Hint: there is a button combination that you must preform to enable download mode it is posted several thousand times in the captivate section I would suggest go and find what it is.

Btw. The button combination happens to be posted in three or four of the stickies. And the forum rules say to read stickies before creating a thread or posting.

I've read them already. I told you I can't get into either mode. I know exactly what the 3 button combination and the download combination is for this phone and since the wrong kernel was flashed on it, it's apparently not working.

Hint: being helpful is great, but when you start talking down to people, you start to become an ass. When that starts to happen, it's best you be quiet and let people who want to come up with a solution to the problem speak.

Thanks.

You need to get a jig then

I'll order a jig and see if that gets me into download mode. Thanks for the explanation. I'll update this once I get some results.

I'm on it. Preciate it.

 

[rodashtoc]

Fixed!

Got the jig, flashed the right kernel back on, game, set, match... 8 bucks well spent. Thanks everyone.

In future reference, you can force the phone into download mode from adb.

Using Doc's Master ROM v7: Cappy edition
