S2 Plus I9105P - Random Restarts

Hi Guys,
i have a big problem with my NEW Samsung Galaxy S2 Plus NFC, i bought this phone on last wednesday (19.03), first run, apps, just fun, no problems at all, but couple days after phone restarts two times in a row, i just left it on table and i hear samsung launch sound, after first reboot, couple minutes later, phone restart again... I was so mad, cuz god damn, this phone is NEW... one or two days after, when i turn on Mobile Data, phone restart again... please, guys, i beg you, how can i fix it? :crying:
I found many threads on the internet about this problem or similiar to this, but without solution.
Sorry for my bad language, but im so mad and in addition im from Poland.

Maybe try flash 4.2.2 rom?

If i flash 4.2.2 from, for example sammobile i don't lose warranty?

Have you succeeded to solve it ? If no, flash it with odin. And yes, you lose the waranty.

Hi!
I can´t say for sure if OP tried of course, but in my sad experience OP does have a point (intentionally or otherwise).
I did check for answers and found the thread you refer to.
For me, hard reset didn´t do the trick.
Upon reset the tablet found my home Network all right and hooked up. I was thrilled - problem solved. :laugh:
Now 2 hours later i´m sitting at my desk at work and the -905 can´t find any networks whatsoever. Depite that my Note 3 clearly detects 2 strong wi-fi networks and 2 weak ditto (on & off).
I am somewhat less than extatic. :crying:
Reboot twice, flightmode on/of. Nothing seems to make any difference.
By my count there are now at least 3 users that report this issue. It may be a bit early but i see a pattern in the far Horizon.
Thoughts & inputs are appreciated.
Regards
ELO

Well,
another option if still have issues, but can maybe go to a local bestbuy with the samsung experience and i would think they should be able to hook it up and do their version of odin and get it all fixed up for ya.. jsut a thought and that might get you fixed up

Hi!
Thanks for the interest & taking the time to ansver.
Living in a small arctic town however (approximately 1500 people) in Greenland we don´t have a lot of bestbuys around here.
I have considered reflashing the rom using Odin myself. If it solves the issue it´s a fairly hassle free repair.

3 people out of several hundred thousand isn't a pattern.
However, losing WiFi after an update is a common Android bug. A reflash (particularly the modem) usually solves it.

Hi!
Statistically i quite agree. Completely off topic I was referring to the old proverb: "Once is chance, twice is coincidence, third time is a pattern".
On topic though it gives me great dissatisfaction to report that reflashing the rom did nothing to remedy the issue.
Downloading the entire rom from Sammobile, latest Odin, MD5# checked out. In short, all i´s dotted & all t´s crossed.
The -905 was sublimely indifferent - this is hastily converging towards frustration
Thoughts appreciated - otherwise i´ll probably just try again.
Regards
Elo

Solved!
Hi
Found it! It´s Passpoint that´s the culprit.
The whys and the hows i haven´t got but i´d downgraded to the old rom - reacquired Wifi - subsequently re-upgraded and Poof like evil magic, wifi was gone.
I muddled about in the wifi settings and was just about to admit defeat, when i shut Passpoint off - simply because i never use it, and the -905 said "Let there be Wifi" :angel:
Afterwards i found out that once wifi is detected and connected i can start passpoint up Again. Then if i move out of coverage and back in again the problem starts all over. Not a big issue since i keep passpoint shut down for now but there you have it.

[Completed] Samsung s4 mini (i9195) connection problems (mostly working on edge, no 3g/H/LTE)

Hi guys,
I have this problem with my galaxy s4 mini: a few days ago, soon after rooting the phone with the procedure found in this forum, mobile network began to work only on edge, and sometimes there is no service at all.
Therefore, I tried to check the sim in another phone, and it works good, I did a hard reset, and nothing changed.
Then, at this point I flashed the rom with a stock firmware, I flashed the modem, but mobile network wasn't working yet, (it was still working on edge).
Thus, I decided to flash the rom with a CM 13 (snapshot), and here something happened !
In fact, LTE/H/3g have begun to work, but only for short periods of time when in use (looking some stuff on the internet), like 10-20 minutes, and only when the battery is almost completely charged, at least until it reached 60%,
then, when it drops below, it begins to have the usual connection problems.
Since I've rooted the phone, I haven't installed any app, I put a sd card in it, another thing is that, when I use mobile network (internet or apps) the phone becomes really hot.
If someone could figure out what could be the problem, I'd really appriciate your help,
Thank you.

Nexus 5 stuck on "Turning wifi on"

Hello all, my old Nexus 5's wifi stopped working back in January for no apparent reason. Everytime I tried turning it on for some strange reason it just Grey's out. The MAC Address is also really weird. I tried looking for a solution but to no avail. I'm starting to think that it's a hardware issue. These are what I've done so far for the past 4 months or so:
- rebooted the phone
- wiped the cache
- wiped data using TWRP
- letting the battery drain and charging it again after a couple weeks
- smacking the back side on my hand (lightly of course)
Any help would be much appreciated. Also, it's not my primary phone anymore so I can't tell whether cellular connection would be working or not.

Just did a factory reset and wiped everything, still nothing. MAC Address is just a solid 2.00.000.00. Also, Bluetooth still works.

Try running a stock 4.4 or 5.01 rom. If the problem still exists, I'd say it's a hardware issue.

Keeps giving me an error Everytime I try flashing the latest KitKat/lollipop. Only marshmallow works

Hmm, I had a similar problem few months ago, tried flashing the latest stock firmware; didn't help and then moved back to a custom ROM. Strangely, it didn't work at that time too but kept the phone the same for an hour and out of nowhere it started working. Seems like the phone is really dying now.

What is the error? Did you try flashing each img file separately rather than using flashall?

Damn you got lucky then. I think mine is just a hardware issue, which is much worse.

Gives me an error about MDU or something like that. I'll send a screenshot in a bit

Still doesn't work for me. I'm gonna try taking apart the phone to see if the wifi chip is ok, hopefully it's not a hardware issue.

Same problem here, even on custom ROMs and factory images,
Is there any hardware solution? Maybe an external WiFi antenna or something like that?

Not that I know of unfortunately. Guess we'll have to buy a new Mobo for the phone

Hi guys! Since today I hopped on the "activating wifi" train too!
I'm on Lineage 14.1 CAF, and did a full wipe and flash, no changes.
I followed a guide in a post here on XDA to recreate the MAC address file, after that wifi worked for a couple of minutes, then went down again.
I thought about flashing MM stock image, but after reading your posts I think i'll keep my phone this way until I buy an OP6.
Luckily I have 15Gb of cellular data

What I did was I opened the phone and took out the motherboard and disconnected the battery from everything, then took out the heatsink that's on top of the wifi chip. It worked for a bit then it stopped working for good. It definitely has to be a software issue because Bluetooth is working fine.

It could be a hardware problem. I have two Nexus 5 motherboards where the wifi tries to turn on and, eventually, the slider goes back to the off position.

Damn, I guess I'll have to change the motherboard to get it working again. I might just sell it as is or for parts since it hasn't been my main phone for a while. But I did want to give it to my nephew...

MY Nexus5 got the same problem WiFi just stopped working suddenly. The mac got some stupid address like 2.00.00.00. I tried every thing still nothing. I have already rooted my nexus so tried different roms but issue still remains.
Then i just remembered about the ROM UBUNTU Touch i have installed it and WiFi in Ubuntu start working again with original mac address. I am currently using Ubuntu touch and didn't try to reinstall the android rom again.if some one try this and got WiFi working like me please inform me that if the WiFi still works if i reinstall android system.
If you want to download Ubuntu touch download it from ubports

I have had the same issue with all LOS based roms. I'm running 15.1. Restoring EFS partition from stock 6.0.1 QL1 does not fix it nor does re-flashing QL1 firmware.
