[Q] Help! 2.2 Problems and 2.1 Revert!

Hi There thismorning I flashed my i5800 that I purchased from Carphone Warehouse with the I5800XWJPF 2.2 firmware from http://forum.xda-developers.com/showthread.php?t=1063940 using ODIN.
The first time I tried it all seemed to be successful, and I then proceeded to root it with SuperOneClick and began restoring my phone using titanium. Then halfway through it crashed, and with no input from me my phone rebooted. It then got stuck on the I5800 boot screen. I finally managed to get it to work be re-flashing the JPF firmware. I Then factory reset the phone (forgot to last time). Now I have finally managed to restore to my phone to how it was.. ish.
When I reboot the phone it take forever to run the Media Scanner and no widgets other that the Google search load up. Also icons are missing. Aswell as thos issues the phone runs slower than it did, and crashes often. I have fired up angry birds and it was just a juttering mess. Based on all this I decided to revert back to 2.1.. and oh oh.. can't find my firmware.
My initial firmwares were:
PDA: I5800XXJG7
Phone: I5800XXJG3
CSC:I5800XXJG5
It was rooted using z4 root and had live wallpapers enabled.
Help!
What can i do to fix this?

Okay, it seems to have now settled down after several reboots, but it seems to loose around 30% of the home screen icons upon reboot. Is this normal? And does it happen on the JPM firmware that was suggested above?

No it is not normal. Do a factory reset, flash any 2.1 rom from www.samfirmware.com and then JPM.

I've got XWJPF and no problems. It runs very smooth. Something else is wrong.

Try flashing it to the earliest stock version of 2.1 that works, do a factory reset, then using Samsung kies, update it to the latest version available on there. Then try and reflash your choice of 2.2 rom. I had similar trouble with mine when I first started. I would recommend flashing CWM recovery as well, the samsung recovery is crap. XXJPQ seems to be available now and is getting some good reviews, fast and stable like JPF, but more up to date. Also try using SuperOneClick to root, has the best results to my knowledge. Some roms take a while to load all the app icons on boot, depending on the amount of apps you have it can sometimes take a little bit. I've found letting the phone go idle for a minute can get rid of the loadup lag. The ram gets topped out easily on the G3 if you have lots of apps that load at startup, which will severely slow the phone down.
Hope this helps!

More Problems
Okay, Now after a few restarts and crossing my fingers the icon thing has started to work, aswell as everything else clearing up. But now the app sizes are very small according to application manager, (angry birds - 2.2mb) and many third party apps reading 0bytes. Another thing is that Bluetooth refuses to work. It vibrates once when enabled, then another 3 times in quick succession and then the force close dialog appears. After clicking force close the box disappears and the phone responds again. I then manage to pai with a device but when I went to send a file, the dialog box and the vibrates appeared again and it refused to send. Any ways to fix?

Factory reset->reflash->factory reset.
Keep back ups!
All that you say is abnormal.

About your disappearing icons:
Are you using the (stock) TouchWiz launcher? If so, that has a (known) bug on 2.2 that all links to apps which were moved to sd card disappear if you unmount the card (which includes reboot). Are the apps that disappear on the sd card?

Reflash
Okay, to start with I will try the factory reset, flash, factory reset that was suggested. And by the way the disappearing apps were not on the sd card... Strange.. If this failds i will do as suggested by flashing to the earliest version, the update via Kies. I was trying to avoid this because of internet allowance..
Thanks for all the replies by the way

I'm halfway through restoring my settings via Titanium, and I keep getting the single vibrate, roughly 10 second delay, than a very fast triple vibrate, exactly the same as it did just before bluetooth crashed... Is something else wrong?

Okay, I've restored rooted and reflashed it and... ... still the same..

Titanium
Is it possible that this is caused by me restoring my phone settings from 2.1 to 2.2 through titanium?

If you need the original firmware to return it to stock pm me and ill upload it somewhere for you

I have just sent a bluetooth file! After another flash and wipe.. but havent restored or rooted. Don't think I will bother really. I now have a working phone! Thank you!

You must restore only apps. Restoring system configurations and apps data will cause problems. If I'm wrong correct me.

No Sound what so ever. No calls, incoming and outgoing. No Video.

Hello. Before I explain, please know I have been moddng and installing custom firmwares on devices for many years now. This is no simple fix. I have no idea how to solve this but I will post everything I did to get the issue and then everything I did trying to fix it to no avail.
Samsung S4 Canadian phone from Bell.
CM 10.2 firmware.
Upgraded the Nightly on Dec. 23rd 2013
After the reboot, I noticed that when I tried to play MP3's, they would not play, it just skipped through all of them.
Putting new MP3's on the card did not help. Neither did putting MP3's on the phone it's self.
I noticed that the phone was making no sounds what so ever. My morning alarm did not go off.
I received a phone call. Phone crashed. Tried to place phone call, screen goes blank, phone crashes. Also learned that any app that utilizes sound crashes.
Tried the obvious fix, restored phone from restore made before the Nightly install.
No sound, no phone. No video.
Installed all previous CM backups (15 in total)
No sound, No phone, no video.
Factory reset.
No sound, No phone, no video.
Fresh Install.
No sound, No phone, no video.
Re flashed TWRP
No sound, No phone, no video.
Flashed CM Recovery.
No sound, No phone, no video.
Went through ALL previous backups. (32 in total before CM was installed on phone)
No sound, No phone, no video.
Flashed to stock ROM from a same ROM that has worked previously.
No sound, No phone, no video.
Used KIES (or however its spelled) to update phone to newest legit firmware.
No sound, No phone, no video. Also no Wi-Fi. seandroid kernal notice does disappear however upon boot.
Factory reset from Samsung native recovery.
No sound, No phone, no video. No Wi-Fi
I have to admit, this is the first issue ever I have not been able to fix or find an answer too after extensive hunting on Google or through these forms. I can guarentee that this is not a hardware issue, this only happened after flashing the CM Nightly on Dec 23rd 2013. I am at a total loss.
Any suggestions? Any fix before I reflash back to stock, update and bring it in to Bell? ( so happy I pay the extra monthly for insurance

Similar thing happened to me. I had to Odin MDL and start from complete scratch. That was the only thing that fixed it after 6 backups and a complete reinstall.
You might also check that your speaker contacts are connected properly if you are comfortable take the device apart.

[Q] Galaxy S4 restarts every 10 minutes

Well for starters, high everyone!
I have an issue with my S4 and I've searched all over but none of what has been recommended helps.
The issue I have is that my phone will restart about every 10 minutes (give or take). I used Reboot Logger to determine this. The phone only restarts when it is idle. It WILL NOT restart if I am using it (screen is on). The weird part is that it doesn't even go through the whole reboot sequence. The screen will stay black the entire time. The notification button pulses and the home buttons will light up like it was restarting though.
I had a bad battery and had it replaced with a stock Samsung battery. I've tried pulling the SD card, pulling the battery for 10 minutes, pulling the battery while the phone is on, and I've performed two factory resets.
The one thing I have noticed is that, after performing the factory reset, I get an "error" under the little android dude. This also happens if I do a cache wipe.
My model is the SPH-L720 running on android v4.3. The phone has never been rooted and there are no software or firmware updates that are found.
I was beginning to think that this was a hardware issue but the consistency in reboot intervals makes me believe otherwise. At this point I'm at a loss. I rooted my old phone but my experience in that area is very limited. I have read that the cache partition is bad from the factory on some of these (hence the error message) so I was thinking about rooting the phone and trying to use a good cache partition, but that's the only other option I could think of.

sounds like a voltage prob....or mem prob... id redownload a new rom..wipe wipe wipe..reinstall and that should fix it
Sent from my SPH-L720 using xda app-developers app

Insufficient voltage at idle was my first thought too, but if you haven't undervolted (since you aren't even rooted), that seems less likely. If I were you, I'd root the phone so I could do more to figure things out. Maybe try bumping up the voltage a little on the lower clock speeds.

Ok, first of all, do not root your phone. As you admitted yourself, you have limited experience in this area, and there is nothing that rooting will do for you. Not to mention, if you think you have a bad cache partition, you don't need root to fix it. Your phone is stock, running the stock kernel, there is no reason to suspect voltage issues that are not hardware related. If you root the phone, you will likely trip KNOX, and void your warranty.
My personal opinion is that your phone has a hardware problem. If you want to truly start over, either recover your phone through KIES, or better yet, download and flash via ODIN a stock MK2 ROM from this forum. Since this is a stock, signed ROM, you will not trip KNOX, and it will rewrite every partition properly on it's own. This is all assuming you don't have a hardware problem. But do not go ahead and try to fix anything yourself besides what I mentioned. You will not succeed, and likely lose your warranty in the process.
Edit: did you buy this phone new or used? If you bought it used, more than likely somebody ruined it for you. And more than likely, you can fix it. If this was a new device, more than likely it will be a warranty issue. That's why you shouldn't do anything to void the warranty.

If you're going to use odin for anything, just make sure you follow someone's directions step by step. Otherwise very bad things can happen.

im also having a slightly similar problem
Problem : The screen after a sleight amount of time of being on, or sometimes instantly when opening the lockscreen it freezes for 10-15 sec then shoots black lines across it, then reboots.
Things ive tried :
1. Installing a new rom ( from AOKP 4.4 and Triforce 4.3)
2. Changing modem (from MJA, MK2, NAE)
3. Changing the type
of Gapps i was using. (4.3 gapps for triforce, aokp 4.4 gapps, and pa gapps)
Current Phone Info:
Rom: aokp_jfltespr_kitkat_nightly_2014-02-08
Modem/Firmware: NAE
Gapps: Pa.gapps 4.4.x
Let me know if you need anything more! plz!

I'll look into Odin before I root. The phone was also purchased new. I spent most of today monkeying around with different settings to see if I could trigger the issue as well. As it turns out, the phone will only restart at idle if it's plugged into the charger, or the wifi is on. If wifi is off and it's not plugged in it's fine. I am also using the stock Samsung charger that came with the phone. Again though, if I'm actively using the phone it doesn't happen (charging or connected to wifi). I did turn the phone off earlier to charge it but would keep freezing at the sprint logo upon boot up. I thought it was bricked for a second... I wiped the cache (didn't do a factory reset) and that fixed it, but now I have that stupid issue where videos won't play on wifi, only on 4G or 3G. It's an issue I thought I had solved.
Le sigh. This is frustrating. The Odin option is looking to be my best bet it seems.

Since you are running a custom source-built ROM, first thing to do would be to ODIN a stock ROM. If the problems go away, you have your answer. If not, this would likely be a warranty issue. Of course you tripped KNOX most likely already.

Alright I'm a little confused as to what exactly I should be using. I found this:

which is a stock ROM. Although I also found this:

which is the stock firmware.
Which one do I use, or do I use both of them?

Follow instructions in the thread. This is a completely stock rom with no root or mods and will not trip the Knox bootloader. If you flash anything other than this, including custom recovery, cf autoroot, etc, you will void your warranty.

rebooting
i had this problem once and it was related to a corrupt file on my sdcard believe it or not. there are Defraggers out there for your android file system and internal SD card but your Ext sc you would have to do on your PC. it worked for me. the one i used is called CLEAN i got it off amazon app store.

That solved my problem, thank you! I spent the last couple days testing it just to be sure I wouldn't be crying wolf. The phone has yet to restart on me even while charging or using wifi. The error message I would receive after a cache wipe or factory reset went away as well. It makes me wonder if the bad partition was what caused my old battery to fail.

Great, I am glad it worked out, and hopefully your problem is resolved. I doubt that your old battery failed due to a bad partition, and I have to wonder how your partition got messed up in the first place, but that's just a curiosity and is irrelevant in the grand scheme of things. Just remember that if you decide to root, cf_autoroot works but will trip the KNOX bootloader and potentially void your warranty.

When WiFi is turned off I get 'Unfortunately System UI has stopped'

This is on two standard Galaxy S5's, with standard ROM, etc - not rooted, or anything else.
Every time I turn off WiFi, or enable Mobile Hotspot, I get 'Unfortunately System UI has stopped'.
To fix I have to Power off/on the phone.
(Turning on WiFi is no problem, just turning it off.)
I have gone into 'Safe Mode', and same issue, so it looks to not be a bad App.
I have also uninstalled 'Google' updates, and again no change...
Any thoughts?

All of a sudden my S5 showed the exact same error message for no aparent reason... I didn't do anything, and now I can't use my phone at all because of that bug. It happens on every boot so I can't even unlock my phone. Tried reinstalling everything, ROM, recovery, kernel, with/without root = still same, what just happened here??
EDIT: Same thing if I'm in Safe Mode -_-

Seeing noone knows a solution here's what I did yesterday.
1. Backed up all my stuff from internal storage to the sd card
2. Did factory reset in TWRP recovery
3. Flashed completely stock official firmware from Samsung
4. Waited for it to boot up and try to restore some of my settings (it restored all folders on their places, made same amount of home screens as I had before the reinstall and downloaded all of my previously installed apps from the Play Store, ofcourse without the cracked ones, and it also restored most apps' data as well so it's not as bad as you may think to factory reset and reinstall everything)
5. Started rooting, flashing TWRP again, installing Dolby Audio, Xposed and everything I had before, took me one full day to set it up as it was before.
Now when I set it up I always make a nandroid backup from when things are working fine, in case it goes crazy for no reason again... Good luck!

when the wifi radio is acting weird, a dirty flash of your current ROM susually fixes is as its probably a radio issue. Id do that before doing anything drastic like the boot-n-nuke Odin flash and starting from scratch (which will fix that issue)

I don't think I have a ROM issue, as I have two S5's, and both have the same issue... and both are standard ROMs.
I will do a factory re-set on one at some point, but this looks to be a 'simpler' issue.
I have tried a full Cache delete, as well as other 'clean' processes.
Nothing works.

I tried to re-flash my stock ROM as @youdoofus said but still had that annoying popup. Try everything you can think of, if all else fails, reset.

well, you can wipe cache, and dalvik 3x each (not kidding about the 3x each), then dirty flash the rom, pray to the gods of android, reboot. If failure occurs, its Odin Nuke time unless you want to try to flash an individual radio file by itself (not recommended)

Freezing and rebooting

Classic "my phone keeps freezing and rebooting". I am quite in the know about flashing roms and such.
It started on the stock firmware 6.1.1 (i think it was). I dd factory resets, cache wipes the lot. It would still randomly reboot.
So i flashed Telstra version of 7.0. Still froze every now and then. Did the same things as above.
Flashed TWRP and wiped everything, flashed Renovate Rom and the bootloader for it, Still did it. Numerus factory resets and wipes of everything. It would freeze at any point from startup, to having setup the phone and making phone calls or on facebook or whatever. It would even freeze in twrp, or loading twrp.
I found that the data partition was corrupt so i re partitioned to ext4. Still nothing. I reformatted every partition so the phone was a complete brick with nothing on it and after flashing clean again it would still do it.
Whats the issue that I'm missing, or is there a way to log so i can find where it keeps getting stuck? It gets hot and blue light flashes and i have to hard reset it or sometimes i have to let the battery drain so i can turn it back on again.
pls help?

Hmm i will give you an advice so you dont have to wait for your battery to drain...just press volume down and power button for like 5 secs and phone will force boot. Anyway back to your problem...did you tried flashing latest stock samsung firmware?

This advice doesn't work with my phone even with holding the buttons for 30 secs and more. For rebooting I can only wait until the battery is completely drained. With little hope for another way shortening time to the next reboot any help is appreciated.

Same here...experiencing the same prob...

Same problem.

pls help?

Sounds like you need your motherboard replaced i had the same issues on marshmallow thought the nougat update would fix it but realized it was a hardware fault not software..left it in store to get fixed and on repair sheet it said faulty motherboard..

As i know some S7 have motherboard hardware problem, mine has too, what help? warranty and they replaced motherboard. But if you root, you can say good bye to warranty, they look at knox first with this problem.
