Rebooting Issue: Rooted

[GleamingDawn]

I've run into a bit of a problem. After several minutes of messing with my phone (Home screen, apps, menus, etc.), it will do one of two things: 1. It will lock and reboot (Happens most of the time, within 2 - 30 minutes between each event) or 2. All the external buttons on the phone will become unresponsive, in which I'll HAVE to mess with the phone until it reboots (Only happened twice). I'm thinking I can post a log of some sort to help narrow down the problem, but I'm not tech savvy enough to know where to start.

Running On:
ZVH - gRom (w/ redRum theme)

Story so far:
1.) I rooted my phone about three-four weeks ago
2.) ... Then, two weeks ago, I dropped my phone in water, preventing it from charging
3.) So I ordered a replacement phone and had it activated... Yesterday
4.) I had this new phone rooted
6.) Then, I took the memory card from the old phone and restored nandroid to the new one
7.) Everything was perfect! Up until five minutes later when the above started happening

Super appreciate any help with figuring out what's happening.

Edit: To help narrow down a little, this isn't a specific problem with the SD card (Although taking it from a drowning android may not have been the best idea). The phone will reset with and without the card present.

Make a quick backup and reflash the ROM fresh and see if it still happens, if it does, the phone is probably messed up. If not, your backups are probably breaking something and you might want to reinstall your stuff from the market and/or however else you may have gotten them.

Edit: Or if the above doesn't help try moving your stuff from SD to your computer and reformatting the card, or maybe just try another SD card.

Already did the backup & restore beforehand, so that won't work at the moment. Already tried reformatting the card (Or I believe what I did was reformatting, not just deleting), but I'll try moving everything to this new card and see if flashing will work. If not, I have the weekend. It's not entirely new to me to have to redownload everything. Did that about six time when I first tried to figure out rooting.

Totally still up for any other ideas, though. Y'know, to save me time.

Fresh install from good card. its possible that the contents are corrupted on the drowned card. Or the card itself is bad

When you say restored everything from the SD card, you don't mean that you nandroid restored your system from the other phone, do you?

If so, that's most likely the problem. Now that I reread it, I do think that's what he meant.

Eh? Explain? Did I miss something super important in one of the stickied threads?

It is true.

 

[GleamingDawn]

So, before I knew it was a no-no to restore nandroid from another SD card (In which I still don't know the exact reasons), I did a couple more things to try to fix my phone:

1.) Moved everything to the new card and restored from backup: Nope
2.) Wiped everything; no restore: Nope
3.) Wiped again and reflashed gRom: ... It worked to a degree. My phone still reboots, but only when I use the camera.

I'm about to try one more thing before I flash the stock rom, unroot, and wipe.

Edit: Edited the top post with more accurate information.

Normally whenever you flash a ROM/kernel combo or more notably a KERNEL that is your problem right there with random reboots.

From having a years worth of experience flashing everything under the sun for my devices I have learned the kernel is the culprit 99.9% of the time. Not that the dev of the kernel did anything wrong because they try to always find a "happy medium" to set their kernel at and from there its up to the user to tweak it further. Another thing I have learned is no two devices are alike. My device setup with the same exact ROM/kernel package will not perform the same as yours, in return it reacts differently to the kernel. There are even situations where you can't run a certain kernel because of the way its setup to function and for whatever reason your phone's processor just don't like it and tells you this by lock ups and random reboots.

Best recommendation is to play slowly with kernel settings, make small adjustments. CPU speed adjustments should be done in steps not big swings. Normally whenever you bump CPU speeds up and down you have to adjust voltages also to compensate for the change in speeds.

Lots of trial and error. Best of luck.

If it was me, I would install stock recovery and flash the zvh update.zip to return to stock. Then do a ##786# reset (you will need a 6 digit number from sprint to do this, tell them your data wasn't working and you wanted to reprovision your phone. Then you can reroot and do a clean flash of the rom of your choice.

Alright, I will. One last request, could someone post a link to a guide on ADB and how to use it? I distinctly remember seeing one, but now that I'm looking for it, it's gone.

You dont even really need to do adb, set up the zvd/zvh automated root tool to restore stock recovery (choose option D).

http://forums.androidcentral.com/lg...70zvd-zvh-100-automated-no-revert-needed.html

Download zvh update.zip ( http://www.mediafire.com/file/q0stlhrasgq6lki/update.zip ), place on the root of the sdcard (not in a folder), boot into recovery and choose apply update.zip.

Boot into android (now stock zvh) and open dialer to enter ##786# just be sure to get that code from sprint customer service first.

Then you can use the zvh automated tool to root and install xionia (choose option A).

Then boot into recovery to create a nandroid backup and then you are safe to start reflashing roms. Make sure to flash the debug-FORMATsystem.zip after performing your wipes but before flashing the rom itself (found here http://files.mysticmidnight.net/zef...s/custom/archive/Debug/Debug-FormatSYSTEM.zip )

Thanks so much Hlxanthus, you're two for two!

I did all the above and now everything's working again (Or maybe I should say, working as much as stock gingerbread will let me)! So ready to start flashing.

Edit: Actually... I do have one question. Is there a stock Sprint Rom somewhere around here? Not that I specifically want that Rom, but y'know... Just in case

Since there is the ZVH update.zip, you can always revert to that if need be to get the stock setup back. Just make sure you have the custom recovery back on the phone first.

Now, I know exactly what your issue is with your phone. Paul627g touched on it in his earlier post too. GRom is the rom you have been running right? That rom is overclocked right from the get go to 748. In your case, I am 99.9% sure that your phone just can't OC that high without issues. I don't know if GRom comes with NoFrills CPU app but if not, get it free from the market and turn your clock speed down a bit and I bet you will have no more issues.
