[Q] Phone keeps rebooting after ROM installation - Android Q&A, Help & Troubleshooting

Hi,
I'm new around, hope this is the right forum...
I have a galaxy s1 (i1900) which I flashed with a new ROM (2.3.6) in the past and then installed 4.2.2 from a zip, and it worked fine for a few months.
Having the same ROM file I used before, I tried to get it back to 2.3.6, as the 4.2.2 didn't work quite well, causing some problems when trying to make phone calls / receive calls.
After flashing the 2.3.6 again, the phone kept rebooting itself. Having read a few different guides online I tried all options - wipe data, wipe cache, wipe dalvik cache... then did some dramatic things like formatting /system, /cache /sdcard... I know it's not a very smart things to do when you don't know what you're doing, but I guess I felt I have nothing to lose at this point...
I also tried to reinstall 4.2.2 again and it only rebooted to the recovery mode whenever turning it on.
When mounting to USB I see no files in the device at all, only a folder called 'clockworkmod' with file called '.recovery_version' inside, and 2 empty folders named 'external_sd' and 'LOST.DIR'. It also shows it has 13.2GB free out of 13.2GB, which is weird, because the os doesn't occupy any of the capacity.
How do I save this poor device?
Many thanks in advance for your kind help!

Phone not provisioned

I have a problem. After finally talkling myself into rooting my phone I was able to pull it off sucessfully, almost. See I havent had service on my phone for 3 months. In that time I have enjoyed using it for wifi, e-mail etc. The phone always kept saying not provisioned a bunch of times but always kept functioning.
I installed cyanogen 7.0.3 (Ithink) last night and after it booted up I said "great I didnt break it" but right in the beginng when I tried to sign into my gmail (at the time already logged into my dads wifi) It wouldnt recognize that I am signed into a wifi. it just kept asking about a data plan. I dont get it.

Try going to Settings > Wireless & network settings > Mobile networks, and unchecking "Data enabled".
That was one of the first things I check. I got no idea why it won’t let me jump on internet or market even though I will see on my phone that I am connected to a strong wifi source. Then I'll use rom manager to restore back to 2.1 and my wifi will suddenly work again. It’s driving me nuts because I am having fun with cyanogen mod but the I’ll revert back to 2.1 because I have no internet
Try bypassing ROM Manager. In general there are all sorts of issues that can occur if you use ROM Manager to get to Clockworkmod on S-ON devices like the Aria. I'm not saying this is the actual cause of your problem, but it's one thing you can try.
Shut the phone off completely then do volume down + power button to get into Clockworkmod and try installing CM7 again.
Also, make sure you are doing a full wipe when you upgrade to CM7.0.3. You can't retain any settings from previous versions.
1) Boot into Clockworkmod
2) Wipe data/factory reset
3) Wipe cache partition
4) Advanced > Wipe dalvik cache
5) Partitions menu > format system
6) Install Cyanogenmod zip from sdcard
7) Install Google Apps zip from sdcard
8) Reboot
Parden my newb status for asking I'm learning quick. but after I go ahead with wiping all my data etc. do I keep super user status or do I have to download various boot drivers and root my phone again?
I also just noticed that as my phone was booting up from clockwork recovery it said at the end
"no sd-ext found. skipping backup of sd-ext" Maybe that could have been the prob?
Last question is I just bought a 8 GB sd a couple days ago, should I partition it while I am doing all this? Thanks alot for the help

Yes you will still be rooted. Clockworkmod will still be installed on your phone (which is what you use to install ROMs), and the ROMs that are available on this site (including CM7.0.3) are already pre-rooted. You shouldn't ever have to use Unrevoked again.

That just means you don't have an ext partition on the SD card. It's normal.
If you partition your SD card and dedicate a portion of it to an ext partition, you can use it for additional app installation space. The Aria's internal memory is somewhat limited so this can be helpful if you like to use a lot of different apps. You don't have to partition the SD card before installing the ROM, although doing it before installing a clean ROM might save you some trouble of having to back up anything from the SD card.
You don't HAVE to partition the card if you don't want to. It's only if you want some extra app space or not.
Great it worked. My WIFI agnolidges me. That was wierd.
Thanks alot for the help.

SGS2 Random Shutdowns

So yes there have been other threads recommending cleaning/tightening battery connectors, using monitoring programs to assess and alert on things like high temp and process cpu spikes etc... a lot of the time the issues raised have been to with someone only recently acquiring their SGS2, or after having "upgraded" their ROM.
Mine seems not to fit any of those scenarios.
A week ago, I found the phone off, so I switched it on and it bootlooped. Nothing new had installed prior, although the was an update to the ZD Box app which I read had problems, but I'd already uninstalled that. So, I rebooted the phone and it seemed to work fine. But no...
At random times whether the phone has been in my pocket or sitting on the desk, I will find the screen is black and none of the hardware buttons do anything. I have to hold the power button for quite some time before I see the Samsung logo and the phone boots up.
It happens several times a day. Battery/CPU monitoring/stats/alert apps show nothing out of the ordinary. I've uninstalled several recentish apps just in case, and no fix. Cleared all caches, fixed permissions, changed modems, no fix.
I'm now in the process of wiping data and flashing a different ROM (a newer version of illusion-xt to the one I've been using... excellent ROM btw), and I'll see if that solves anything.
What's weird is that I've had this phone for nearly a year and it's only just started happening now.
I'm wondering whether this sort of issue has become common with the SGS2 recently. Anyone else experiencing this, and is there are solution for it?
See how you go with the new rom.
If it's still happening, go back & do a completely clean install of stock; format cache, data, system, & internal sd card then flash stock rom in Odin (don't install any apps at all) & run that for a few days. If it's still happening on a relatively 'clean' stock phone, that probably indicates a hardware issue. Could be something simple like the battery, could be the USB/charging circuitry problem we see on here a bit or some other hardware problem.
See how you go with it & post back here.

Followed your recommended steps with the newer ROM. Seemed to be good for a day. I then found my phone off again while it was sitting next to me. I had just installed an app (from "untrusted" sources) just prior to this. So I uninstalled that. Found my phone off again a few minutes ago. This time the phone was hot and about 20% of the battery had drained.
Think I need to do another wipe of everything (except external SD) in case that app was the culprit?
[got a I9100]
if i were you i do this....
save my video/mp3.. stuff
remove microsd
remove sim
using cwm format system, data cache, dalvik, sdcard/emmc (depends on your cwm)
using odin flash a GB rom (i usually go with LA2 / JPLPC [ICS])
after first boot and few minutes dial *2767*3855#
next boot ill setup google account but will not do auto restore / untick auto restore.
shutdown remove battery put the simcard and see how it goes for a day or 2
It's switched off three more times today. The last time it happened the app "Battery Monitor Widget" alerted a "Voltage out of range" warning.
So far nothing's ever gone wrong while the phone is charging.
I may try formatting as has been suggested, but I think I'll try using a new battery first.
Please forgive my daftness as it seems I've misunderstood the instructions here.
Upon booting into CWM Recovery (I have v5.0.2.7) and navigating to "Mounts and Storage" I've discovered what you both mean by "format" in your instructions.
Would this mean following the Gingerbread section of the guide at http://forum.xda-developers.com/showthread.php?t=1457458 is what I need to do to get up and running, and then continue with the remaining instructions in this thread?

I have had this issue with certain ROMs in the past where I would get a black screen and no response from the hardware buttons. I found that on installing the ROM everything worked fine. Then I would go ahead and restore my apps, still everything was fine.... but once I configured Exchange sync I would run into the issue. My only option was to go back to a ROM that I knew worked on my device correctly.
In reply to your question above, If you have a ROM downloaded that you can flash in CWM then so long as it is stored on your SDCard you can format the system, data, internal SD and wipe cache, delvik cache from CWM. In doing this I would recommend making sure you know exactly what "internal SD" CWM is talking about. To be sure you could remove your SD card. I made the mistake of formatting the wrong card once and spent the next day recovering the data from it.
If you have the same issue with a new ROM then i'd recommend going back to a stock ROM using the link you posted.
Hope this helps.
I took my sdcard and sim out and rebooted just so I could see what would show up in the file manager. It would seem like there are no apps or mp3's or pics or anything "additional" available.
Strange as I don't recall ever using app to SD, and I could've sworn I saved at least a few MP3s and pics to the phone.
Maybe I'm just not looking in the right place. Where would I normally find my app folders without the sdcard being present?
Ahh... so once you put the sim in (but still without sdcard) apps folders show up in "/sdcard"
hmm... does this sound correct?
why are you making things difficult?
put your sdcard back, open file browser goto sdcard dcim
you will find pics and videos there if they are saved on your phone storage. copy them to micro sdcard.
simple
if you are on aosp rom than the structure is little different
PS: doesn't matter your sim is in or out.
Stock ROM
/sdcard
/sdcard/external_sd
AOSP ROM
/sdcard
/emmc
As instructed I formatted partitions, installed latest official ICS ROM (for Australia) from sammobile.com using ODIN. Didn't install any apps. Didn't sync. I still have the "black-screen-freeze" at least once a day for several days. Today it's done it 5 times already. Sometimes I find the phone is hot, sometimes not, and a couple of times I've found the battery drained as well.
I can't seem to find a standard pattern that's reproducible.
What now?

Non-booting SII with CM 7.1

As of yesterday, my CM7.1 phone won't boot - it gets stuck at the "rotating arrow" blue Android for ever. It's a Samsung Galaxy S II GT-9100.
I have been running CM 7.1.0 for several happy months now, and haven't tried to install or upgrade my ROM. The last action I took before this happened is that I made a full system backup (using CWM 5.0.2.6).
That backup is present on the internal memory. I can boot into recovery, mount drives and access devices using adb shell. So I do have an opportunity to fix what's broken, if I can work out what it is.
Given that the last thing I did was a backup, I checked to see if any of the partitions were full, but none are. (None is more than 42% full according to df; although strangely, df does not show any partition mounted on /.) I tried making another backup, watching carefully - that worked fine. I tried restoring the first backup - no improvement.
I've also tried wiping everything Recovery allows me to that's non data-destructive - cache, Dalvik cache etc. It hasn't helped.
How do I work out what's wrong? Is there a boot log file anywhere which might give me a clue as to what is wrong? I've searched for "*.log" but can't find anything obvious.
I don't want to do a factory wipe if I can avoid it, because obviously that will lose all my data. If I do a factory wipe and restore just the data partition, does that put me pretty much back where I was? If so, how do I restore just the data partition? The Restore option in CWM Recovery seems to do full backups only, and only from a particular directory.
The original CM and Google Apps zips are still on the internal SD (same versions as are currently not working). Would it be worth trying to reinstall those, without wiping? Or would that be data-destructive?
Any other ideas?
Thanks!

SOLVED - remove 0-byte data/system/profiles.xml
I tried doing a full factory reset from Recovery. This got the phone booting again, but without any of my data . Fortunately, ClockWorkMod has a "partial backup restore" function. I restored the data partition... and the phone stopped booting again.
So this is progress. I now had some idea where the problem lay. I finally found it using a laborious 5-minutes-per-cycle manual bisection technique. Delete half the stuff on the data partition, reboot, if it still fails, delete more, reboot... once you get it to boot, restore the data partition, narrow it down further. Once you find a top-level directory, repeat the process inside it.
The result: the existence of a single 0-byte file stopped my phone from booting entirely. The file was: data/system/profiles.xml.
I have no idea what that file does (there are only a few references online), how a 0-byte version of it got created, or why having it existent but empty breaks things but if it's not present everything works fine. I have no idea if anyone else will ever see this problem, or if they will ever find this forum post. But still, here's my Wisdom of the Ancients (google the phrase for the relevant XKCD comic).

[Q] HELP! cant restore my backup and liquidsmooth custom rom not working on GS3 att

Hey guys.Im kinda a noob, so bear with me. I have a SGH i747 (att galaxy s3) and I rooted it on my mac using motochopper. I backed up all my apps and system data with titianium backup to my SD card, and i also backed up my stock ROM to my internal storage using ROM Manager. I then downloaded liquid smooth using my phones browser, and then I selected it within ROM manager and clicked "reboot and install' (keep in mind, i didn't wipe memory or anything) So it was stuck at the boot screen. Then i realized what i did and went and wiped data/factory reset, dalvic cache, and the other cache, within Clockworld mod recovery (vol up + power + home). After that, it worked, but only to find that all my apps were gone, and the play store and browser app didnt work. so basically softbricked however I can make phone calls and text (lost all contacts). Then i went into cwm and tried to restore my phone, at first it came up with two backups (neither of which had the name I named my backup) but said no files found and then when I mounted my storage, the bottom one said md5 mismatch but the top one worked. the top one would work for about 6 min then while it was restoring data it would reboot into liquid smooth and i would have like 3 apps i didnt have before (other times i would get stuck at the boot screen). I also tried restoring it right after I wiped data/ factory reset and cleared the caches, but then it would get stuck at the liquidsmooth boot screen. Tried pretty much everything.
I just want my phone back the way it was before root or anything, with all my data. But I backed up all my stuff besides apps to KIES, so willing to reset it to stock firmware if possible
need all the help i can get. thank you all very much

Phone is bootlooping after attempted ROM update

I was running AOKP 4.3 and downloaded the latest 10/30 update. I flashed in CWM recovery and everything took as normal. I wiped cache and dalvik and then rebooted. Apps updated as normal and lockscreen presented. I unlocked and immediately received two force closes (timely & swype) if I click them or not, if I unlock or not, the phone will crash and reboot every 6 or so seconds. Luckily, if I'm quick, I can reboot into recovery. I am in CWM but my external SD card won't mount so I can't load anything onto it and attempt a new flash and the only rom file on my internal SD is the one that got me in trouble here. I've gone back into recovery and attempted to wipe data/factory reset/etc. and nothing changes. Internal storage won't mount when I'm connected to my computer with a cable.
I don't mind losing everything and starting from scratch. I've tried to seek out my own info but there is SOO many threads and videos and I don't know where to start. Can someone please tell me the most efficient way to get back to a clean start? I was on JellyBeans from 1-22 and looking back that was probably more my speed. I shouldn't have tried to switch to 4.3 at all. I was able to run AOKP for about two months without issue but I seem to be out of my element here.
Can anyone smarter than me please take pity on me here? Sorry to waste your time as well.
Try just wiping the system, reflash rom and gapps. I think this keeps your apps in tact, if just not just use tb and restore. Otherwise full wipe sounds necessary, but not horrible. Just restore everything with tb
