[Q] Random reboots, bootloops, etc - Samsung Galaxy Exhibit 4G

Ok so I'm pretty sure my phone is done for, but I thought I'd see if anyone knew a solution before I go buy a new phone
Yesterday I dropped my phone (which was running Slimbean), but I popped the battery back in and it worked fine. Then about three hours later, it randomly shut off while I was using it, then started going into a bootloop. Occasionally it will start up all the way, but I'm lucky if its on for 10 minutes before turns back off and starts bootlooping again. I got it to boot into CWM, (the first time it shut off while I was in CWM) and wiped everything and reflashed Slimbeam, but it didn't change anything. Any ideas?

Go back in and do wipes on everything but external drive reflash wipe cache + dalvik cache + fix permissions then boot. Let sit 10 minutes before doing g any setup with Google or phone. This allows all drivers to load and configure prior to having more data to configure.

Need help please...phone reboot problems

Last night, I downloaded InnovationsOS v3 from the Nexus One Android Development forum. Prior to this I was using FRF50, and I have a rooted Tmobile Nexus One. I wiped the phone back to factory settings and also wiped the Dalvik cache (as I've been told in the past). Flashing went just fine and within a few minutes I had InnovationsOS after a reboot. (Let me just say, with this one minor exception, InnovationsOS looks incredible and I loved every minute of it).
After install, I set up AdFree which removes ads. I decided to do a quick reboot. The reboot wasn't so quick, and it stuck on the startup screen (the Nexus One/Google logo with the unlocked symbol below) for about 3 minutes. I didn't think this was good, so I tried a battery pull hoping for a normal reboot. Instead, what I got was the android falling out of the box. I tried a battery pull again and attempted to enter recovery, which worked. I wiped, and reloaded FRF50, and rebooted. I got the android and the box image, which wouldn't let me even boot into recovery anymore after several battery pulls. After a couple minutes of being completely stumped (and scared lifeless) I let the phone sit, and somehow it booted into recovery, where I wiped (again) and flashed InnovationsOS (again). After it loaded, it rebooted, and it's been working great since then, with the exception of one minor screen/keyboard bug...I press S, and get Z, or I press delete, and I get enter, etc. Plus hitting OK or Cancel on dialog boxes is impossible and need to use the trackball.
So, I would like to reboot to fix this problem and want to know what will happen, and I want to know what I did wrong above. I know all this sounds completely noob for this forum but I'm willing to learn, which is why I've been experimenting with rooting and flashing roms.
Thanks a lot, any help is appreciated.

[Q] Corrupted /cache on CM7

Well, something interesting just happened with my CM7. I've beed running it for 4 days and it has been a completely different device (for the good). But 30min ago everything started force closing (3G Watchdog, Gmail, G+). I tried to reboot but then completely stuck. It couldn't move past the LG screen (just turned off). It wouldn't even boot into CWM. Then I realized if i kept the power button pressed, I can work my way through CWM. As soon as I released it, it will turn off. So I managed to wipe cache and dalvik from there and all of the sudden everything is back to normal.
At first I thought I lost EXT4 journaling, but just checked and it's still there. Did anyone face something similar? This was completely weird and freaky. I'm glad everything is OK.
never had such a problem or heard of it before. i know that when i flash a new build without wiping cache and dalvik my phone is very unstable. also a complete wipe and advanced restore data does wonders.

I wiped/factory restored before flashing CM (4 days ago). I noticed someone mentioned something similar (force closes and such) in the CM nightlies thread. I managed to check what was the reason of force closes (before I couldn't even boot) and every time it was because of SQLite error. Seems like apps weren't able to access their database files (which are in /data I suppose).
It really looks like a standard boot loop which happens sometimes after a installing a new build, but this was just out of the blue. Will see how it behaves in the next few days.

[Q] CM9 Reboot Issue

I just installed CM9 via the Novacom2 method. The tablet seems to reboot itself after a few minutes of being booted up for no apparent reason. I can start up the device, and not even touch one thing, and after a bit it will self reboot.
Anyone experiencing this? Should I do a reinstall? Novacom2 method, or a complete factory reset with CWM?
CM9 runs extremely smooth otherwise, but I can't have it up for more than 5 minutes with a self reboot. It's bizarre.
Thanks in advance people...
I meant ACMEInstaller2 where I wrote Novacom2 ....
The only time I got random reboot is if I try to overclock. I went to replace CWM with TWRP today, and checked in CPUspy something quick. I had 36 hours of up time (remember this only dropped 4 days ago). Initially I tried to OC, even only going one step up I got freezes, and reboots. But leaving it at stock frequencies I have zero stability issues.
I would say to start fresh. With a fresh downloaded copy. Go into CWM and wipe data / factory reset, wipe cache, advanced > wipe dalvik, mounts > format system, data, cache, then reinstall, and install the charge fix. Then don't restore anything, and see if that fixes it.

that may be the route I go. After about 15 reboots it is currently holding steady I have not made any interventions.
As a side issue, I get email notifications but the email app crashes upon opening. Gmail works fine though....

I did a fresh start as above and the CM9 from is running problem free and 10x better than before when I had done the acmeinstaller2 method. Thanks button hit.

Try fixing permissions and wiping up cache from CWM, that fixes the reboots after power-on for me.
It used to do it if I left the screen to go off, but is fine now
I too am having reboot issues, but it only happens when I'm doing something. So far trying to open the Photoshop PS Touch app will cause a reboot, clicking settings in boat browser, etc. It's strange as hell.
I as well get the stock android mail client crashing when opened but its notifacations and gmail all work. I just installed maildroid and disabled stock email and seems to work OK

I have the same issue, but normally when the screen is on, it always reboots when I try to connect to usb storage, I have a galaxy s2 running on stable(nightly had too many bugs). anyone has the same problem?
I usually get reboots when I let the screen turn off due to inactivity. I tried installing TWRP and doing a clean install from there but it rebooted at the setup screen for CM9. I've had reboot issues since I first installed CM9, but its improved a little bit. I did try uninstalling android completely then reinstalling, but still got reboots. Does anyone have any other suggestions?
I think the best thing to do is use ACMEUninstaller to complete remove Android from your TP, then reinstall from scratch. I had reboot issues after upgrading from CM7a2 until I did a complete wipe.

[Q][GT-I9001] Ivendor CM10 plus CastagnaIT Kernel (from Softreboot to Hardbrick)

Hello everyone,
I just hardbricked my SGS+ and now I'm a bit curious how this could happen.
This is what I did:
I used to run CM9 RC5 from arco68 along with the Kernel for ICS from Christopher83 and CWM 6.0.1.2.
Because my phone always lost the wifi-connection and also had some freezes I decided to try out CM10 Beta 3 from ivendor.
I backuped my phone, downloaded the zips and even verified the MD5sums. Next I flashed CWM 6.0.1.9 as recommended in the thread from ivendor.
After exporting the nandroid backup and other stuff like photos to my computer I wiped everything as mentioned in the thread, flashed the two zips and rebooted. Everything went fine and I was almost ready with setting up my phone again when I got my first softreboot.
Suddenly it showed the CM-bootlogo and after maybe 10 seconds I was back on my homescreen. I got another two or three softreboots until I decided to flash the Kernel 3.x from CastagnaIT.
I rebooted into recovery, wiped cache and dalvik cache, flashed the zip and rebooted.
Now I wanted to reboot into recovery again to fix permissions but instead I got a softreboot and my phone stuck at the CM10 bootlogo.
I waited for around 5 minutes and then I just turned the phone off and booted into the recovery mode.
Because I wanted a clean install without any problems like softreboots I decided to wipe my phone again (data, cache, system) and just reflash the zip for CM10. And at this point everything went wrong.
I flashed CM10 but when I tried to flash gapps my phone just turned off. And no, the battery was not empty. In fact the battery was at around 50-60% and my phone was also connected to my computer.
I tried to turn on my phone but now it stuck at the Samsung bootlogo.
The next thing I did was probably a horrible mistake. I tried to un-brick my phone but I did not realize that I could boot into download mode without problems so I guess my phone wasn't softbricked at all.
Well, after that I still stuck at the Samsung bootlogo and couldn't enter recovery mode. I got into download mode somehow and maybe this was my second mistake. I tried to flash the "i9001Reset.zip" via Odin. Everything went fine but when Odin said "Close serial port and wait until rebooting" my phone was completely dead. I think it was while I tried to flash the reset-file when I got a message like "MBR: read failed". So somehow I managed to destroy my master boot record.
Now I can't turn on my phone or enter download nor recovery mode. I already removed the battery for about 45 minutes but this didn't work either.
My phone is dead but at least I saved the important data and maybe I'll get a new one through warranty. Or I just buy a Nexus 4.
My questions are:
What did I do wrong especially when I tried to save my phone?
How can I prevent such things from happening?
And at which point I should have got help here in the forum or elsewhere?
I would really appreciate some tips for the future because I already flashed and used a lot of different ROMs but this is the first time something really went wrong.
Thanks for reading and thanks for your help in advance.

[Q] M7 restart 1 minute after starting

Hi all,
My battery got drained yesterday night and i charged the phone when it was off.
When I'm starting the phone everything looks OK but after a minute its restarting.
I'm using TEAMWIN recovery, so i tried to clear cache and dalvik cache, which did not resolved the issue.
I restored an old backup and that backup works just fine with no restarts what so ever.
What can be the issue? how can i load my phone? even just for 20 minutes so i can backup properly.
Please help!
Could not find a way around it - pushed new rom

Could not find a way around the issue but i think the cause was an air update (on a rooted phone+TeamWin recovery)
I pushed a "reset rom" (from htc1guru) without deleting data. did all the setup and app downloading during Germany-Ghanan 2-2, so it wasn't that bad .
