[Q] N7100: no mobile network, no imei, no baseband - Galaxy Note II Q&A, Help & Troubleshooting

hi guys.
i had an accident with my bike on sunday and my phone seems to be f*cked since then. but let me explain:
well i had an accident and somehow fell on my phone, now there is bump in the plastic backcover and in the sd card slot underneath. it is quite deep, maybe 1.5mm. soon after that i realised that my phone is no longer connecting to mobile networks, the baseband is unknown, just like the imei. also the power/lockscreen button isn't working anymore as long as the phone is turned on (it works to turn it on or to access recovery/download mode. i was running jellybam 9.2.0 for weeks without any problem.
so after that i got home i first did a fullwipe and a reinstall of jellybam -> still same problem.
then i tried to enter download mode. i got to the "press volume up to continue, press volume down to restart"-screen and i pressed volume up -> nothing happend
so i went into cwm -> advanced (i think) -> restart bootloader. so now i was in download mode (the proper download mode)
at this point i thought it was a pure hardware problem because my wifi appeared to be not working too. i also thought that i might be able to claim warranty so i installed the N7100XXDMB2 firmware from this thread:
http://forum.xda-developers.com/showpost.php?p=32273406&postcount=5
my wifi seems to be working now so i thought that i could just restore my EFS backup and it might all be fine again (except the bump) but i would have to root my phone to be able to do that and like mentioned before the download mode only works to a certian very useless point.
also i now have the stock recovery, which i can enter, but i can't select anything in there because my power button won't work.
to put it all in a nutshell: i have unknown baseband, unknown imei, a power button that stops working as soon as the device is turned on and also doesn't work in stock recovery, a volume up button that doesn't want me to access the download mode, an EFS backup which i'm unable to restore, no clue if it is a hardware or software problem and severe depression.
the attached picture shows where the bump is. it is quite deep, like mentioned before. made the sd slot completly unuseable.
i'm desperate, please help.
also: i was using the phone (making calls, internet) a few minutes before the bike accident

Well, if you're back to stock and you can claim warranty, then that's the best option.

[Q] Help please! 3x vibrate and amber flashing light after removing battery! (brick?)

Hey guys, I'm normally silent in these forums 'cause I've never had a brick, just by reading correctly. This problem I'm having isn't a flashing brick! What happened is the following:
I know that the DHD in combi with my BT car radio is somewhat difficult (because of bad HTC coding). It seems that when I have my facebook friends in my contacts that the DHD starts slowing down and eventually hang when connected to the radio, because my radio tries to get every contact including it's info. Normally I do not sync my FB contacts with my DHD however I must have mistakingly done this.
Today I connected to my car radio and after getting out of the car my DHD showed that it was still connected (a sign that my DHD had the hang problem again). I turned of BT (took a hell of a time) and contiued on. When I came back I tried connecting the DHD again, however when I pushed the BT checkmark in settings it showed BT on, but no BT connection came up. So I went into BT settings only to find that BT wasn't turned on, then in the BT settings I checked turn BT on.
At that moment my DHD hang instantly, no inputs were registered at all. I waited a few minutes but nothing changed (I could still see the screen frozen at turning on BT). So I took out the battery and reinserted it, but when a pushed the power, the phone vibrated thrice and then did not boot, but only showed a flashing amber led.
I have rooted, S-offed and did the whole shebang to flash my DHD once. This was a long time ago and I haven't had any problems, all was OK. So at first I tried to search the forums, what might have happened. No post seems to be the same as my problem, because everyone is having these problems after an incorrect flash (my flash was correct, cause I've been using the ROM for more than 4 months!). Still I tried the solutions given in these posts (enter fastboot and flash again).
But it seems my DHD won't go into fastboot. When I hold VOLdown&power my DHD vibrates 5 times and shows a steady green led. So I thought maybe flashing a new ROM resolves the problem. If I cycle the battery and then connect is to my computer, my DHD goes into Clockwork recovery. From there I flased a new ROM to my DHD (update.zip method), but to no avail. I've factoryresetted, cleared al data, wiped battery stats, all to no avail...
As of this moment I'm at the end of my knowledge, I've done everything I know could have helped, but nothing did. Therefore I'm asking you, the Oracle of XDA (users), please does anyone have any clue what happened to my DHD and if so, how do I resolve the problem!
Thanks in advance for every little motivation/obligation you show be giving me your insights!
Info:
ROM: Android Revolution HD 2.0.9
CWM Recovery: 2.5.1.3
I've allready wiped battery stats as per this topic!
Additional thoughts: Might a hardware fault be the reason? Because it happened after some problems with BT, and also because I'm still able to correctly flash new ROMS with CWM though the problem remains?
Allright, so nobody know an answer I'm guessing... I've started the replacement process with my insurance company. However I'd still would like it if someone would know what the heck I did wrong...
Have you tried flashing a new radio, as that is what controls the hardware?
All a new ROM will do is update the RIL, not the radio.

It does more than likely seem like a hardware fault so it cant really be solved with software changes. Although I still would have tried to flash an RUU which updates basically everything on the phone to bare stock.
Use an RUU via your pc (v2.36 or lower so you can root it again) to restore to an out of the box state.
Allright guys, thanks for your ideas! I'm however experiencing problems trying your idea's. fFashing a radio or flashing a stock rom are not possible, because I need a connection with my computer. This connection is not possible, if I start the phone normally (or with vol down) I get the amber flashing light or the green steady light. Both do not connect to my pc, I get some device "Qualcomm CDMA Technologies MSN" for which windows can't find any drivers. When I let the DHD go into QWM recovery, the RUU won't find the DHD.
So I've tried extracting the RUU rom en putting this on the SDCARD of the DHD, but when I try to install it via CWM Recovery it says that it's an invalid file...
I actually bricked mine on purpose, and the thing that happened when it got bricked was that no lights and no life at all we're visible on the phone...
Atleast you get shakes and lights, thats a good sign!
Sadly i don't know what has to be done to restore it, but maybe Jkoljo does, PM him about your problem, if you get an assistance and some solving, write back here for your solution for others to use in the future!
They hang out in the Android Revolution HD IRC Channel, thats where i would go tbh.. Live support ftw!
Edit: While reading your above statement, it seems your drivers may be faulty in windows, redownload HTC Sync from htc.com, install, reboot, and try again.
The "Qualcomm CDMA ..." notification on the PC is a sign for the Qualcomm service mode. Also the 3 vibrates and the orange light is an indicator for that. You can enter this mode by pressing vol+ and power your device.
Stupid question, but is it possible that your vol+ button is stuck or something like that?
And you said you're able to enter CWM? how? I'm asking because you said you can't enter the bootloader.
I'll do some research when i get home today.
Meanwhile Try if ADB/Fastboot sees your phone
Edit: just checked my theory of the broken vol+ button: i held down my vol + button, took my battery out, reinserted it and powered up my phone. Result: 3 vibrates and a flashing orange light.
Then i did the same, but held down vol - ( vol+ still pressed). Result: your second phenomenon: a few vibrates and the green light stays on.
So I think this proves my theory because this is exactly what you described
I suggest you to play a bit with the vol+ button. Maybe the button will work again then

Well, I'm gonna fire up IRC then and try get some help. It's indeed not bricked as far as I'm guessing cause I do indeed have lights and I'm able to boot into CWM!

Right I'm guessing this is my problem! Just two days prior to resetting I started having problems with my VOL+ button (wouldn't work, only VOL- worked). So I'm guessing my hardware VOL+ button is broken and stuck to pressed...?
To answer your question about CWM: When I take out the battery so the phone is powered down, then reinsert the battery, connect the phone to the adapter or my computer (without pressing the power button), the phone boots into CWM after about 1 minute!
So after consolidating all the answers I'm guessing this is my problem: Hardware VOL+ is constantly pressed, therefore the phone boots consequently into Qualcomm service mode. Everything seems to be OK (flashing able to CWM), though just this little VOL+ problem puts my phone into an unusable brick...
The problem is that I'm not able to repair this myself (when I would try this, I'm guessing I'll break the seals therefore my insurance won't pay)... Anyone an idea how to circumvent the VOL+ button problem, without opening up my phone?

Do you have needles at home? The ones you use when you repair cloth.. Try using one very carefully behind the volume +, you could also take a bit of A4 Paper, cut out some of it and make it fit between the gap of the Volume button, and try getting dirt out of there.
Allright, I've tried cleaning the VOL+ key but it still won't work. As a matter of fact I can feel a little "click" when pressing the VOL+ key, so I'm guessing the mechanical part of the key is working correctly. However when in CWM I can only use the VOL- key to switch thru the options, VOL+ is not registered by the phone. Therefore my assumption is that the there's a problem on the PCB with the VOL+ key, ergo a hardware fault... Insurance has been called and I'm up for a switch, now let's hope the insurance doesn't figure out I've rooted and installed another ROM than stock!
At least I wan't to thank all of you who've tried to help me! My ego has been saved, knowing it's indeed a hardware fault .
Cant you use adb within cwm to adb reboot bootloader?

I've got the exact same problem! I don't have insurance on it though. And, im a day late for warranty.
What am i supposed to do? Any suggestions? Will htc deny my request to fix it coz it had a custom firmware?
Any help of any sort is appreciated.
I had exactly the same problem, and I'm sorry to say that I had to have it repaired. My button would also "click", but not register.
Maybe if you are buy a new power button from eBay?
Realising this is an old thread, but still:
I was just experiencing the same problem after I did a reboot to let one of my friends borrow my DHD to turn off the PIN code check on his SIM.
It started with the blinking lights (black screen), then I pulled the battery and found that my DHD was only accessible through ADB in recovery mode.
Did a couple of "ADB reboot" without any success, then tried using "ADB reboot recovery", which seemed to work (still black screen though), and then I did a "ADB reboot".
Back to normal!
hi , i had this issue too , its bcz of the moisture ur cell phone has absorb and as HTC desire HD very sensitive with its volume rocker area , the first thing that will be affected with moisture is ur volumer rocker circuit , try making it dry with a hair dryer blower or place ur phone in a rice sack for a day .
i am sure it will work .

[Q] Help screen turns on randomly

Hi guys,
I am facing a huge problem with my mobile of late (Xperia Arc LT15i). I recently flashed a kernel (Stock ICS Kernel 4.1.B.0.431 with CWM 5.5.0.4) with the stock ICS .431 running on it. I am not sure if it is a co-incidence or not but i am having facing screen turning on randomly of late.
It is highly erratic no proper timing or such. Some times it turns on immediately after i turn it of using the power button or after some time. It also turns on continuously 3-4 times after it times out once it turns on.
I tried flashing back to the stock kernel found in the global firmware ftf. But the problem still persists.:crying::crying:
I tried searching for it but haven't found out any solution. Can anyone kindly help me with this or provide a link to the solution if there is any???
Ps. it is unlocked and out of warranty (more than a year old).
lol problem
have your powerbutton an issue? try that: boot to cmw, select advanced and than key test. if you don't pressed any key, but there are numbers for keys recently pressed your power button got an issue. (would also work with home button)
if not it must be a software defect..
simply use flashtool, reflash with everything wiped, backup your sd card and format, copy again on sd card, and try if problem persists. that would be not realistic ;D

how long do you recommend me to run that test? If in case there is a hardware problem how do i take care of it???
Not sure what your problem is, but I believe that Sony warranty is for 2 years. Well that's what they told me when I had my cracks repaired after 13 months : )

[Q] Can't boot or go into download mode

Hey everyone,
My phone won't boot, go into recovery or go into download mode. I was on FrostyJB but was going to change to a 4.2 ROM, so I was going through my normal backup process. I set Titanium Backup to backup all apps and then left it for a while. When I came back later to pick up my phone I checked the lock screen for the time but did not unlock it. About 10 minutes after this I attempted to wake my phone, but it would not respond. I pulled the battery and attempted to reboot it. The soft keys lit up but the screen stayed black. When I try to put it into download mode it just vibrates occasionally. I was switching ROMs also due to the fact that my phone was filled up with "system data" and I needed the storage for my trip to Colorado in approximately 6 hours now. Any help is greatly appreciated and if its not too much trouble please respond quickly because I'd like to have a working phone during my trip.
Thanks in advance!
Ok, so I've managed to connect it to Odin by pressing the buttons blindly (the screen never lit up). I flashed a new recovery and rebooted it but no cigar. I assume my screen is broken somehow. I guess I'll take it to a Tmo store when I get back from vacation, it's a shame I won't have it for the trip >.<
Did you try pressing volume up + power + home key to get into recovery? Also if the soft keys lit up while trying to get into download mode then it may still be in download mode even though the screen is black. That can happen due to various things. To be sure I would connect it to a pc and see if Odin can identify it. If so then you can try flashing it back to stock and see if that makes any difference.

I just had very similar situation backing up system on TWRP (fell asleep and phone completely discharged while in recovery).
1)Open ODIN on PC,
2)Pull battery out of phone.
3)Connect phone to pc w/ usb
4) Put battery in
5) hold down volume, home button and power button
6) Took me immediately into download mode
..good luck

[Q] Welcome screen and Lock screen missing after flashing STOCK ROM

Hey! Need some help if possible. I was messing around with my Captivate Glide. Tried to install some other ROM's but all of them made the phone lost the baseband and IMEI (EFS). I tried restoring the EFS using EFS Pro Tool, but my phone is not being recognized while on CM 11. I decided just to flash back to stock, using the I927UCLJ3_I927ATTLJ3_ATT (which was the only ROM that was showing up the IMEI and got connectivity).
Something that's been bugging me is that after doing all this, the phone boots normally, but there was no welcome screen, it just jumped straight to the main menu without asking for the google account. On top of that, the power button no longer shows the options it did before (reboot, power off). With one press it powers off the screen. If I press it for 2 seconds the phone turns off. There's no even a lock screen on my phone. I've been unable to set lock screen security options. Any options that I select are useless. They do show up under settings, but they don't do anything.
I've been trying everything to get this options back, but I'm not sure how to. I've already flashed my phone to stock, tried with other ROMS, using the same I927ATTLJ3 as reference (since it's the only one that shows the IMEI for me) but nothing. It was showing on CM11 though, all power options where working, as well as the lock screen options. I'm desperate now.
Any help on this?

Have you factory reset your phone? That described things can happen especially when switching between ROMs

Help flashing my device

Im looking to flash my galaxy s7 active because, for some unkown reason the os is corrupt or has a virus.
I have not downloaded anything, all i did was charge it while i slept, picked it up an hour ago and the voulme keeps going down no matter if i press the key or not, the button isnt damaged the voulme menu never leaves the top of device like some ghost hand is permently holding back on the volume dunno wtf that is. I did a factory reset, that didnt fix the issue. The phone is permmently stuck in safe mode, I have tried to enter recovery mode and it gets stuck in a boot loop or opens the light blue screen with the explaination point, the only options is download custom os or cancel. I would like your help on what software i need to fix my somehow randomly damaged device.

Your phone doesn't have a virus. The fact that you already did a factory reset has already reverted your OS back to retail apps and settings, just like how you first got it.
Given the scenarios you provided, it seems that your volume down-button is indeed "stuck" internally (for some reason). Samsung's universal safe mode trigger is to "press-hold down button while booting"--since your vol-down button is stuck, every time you boot, it will always be in safe mode.
You might want to remove the phone case if you have one installed. Then try to inspect the volume down button a bit closer. If all else fails, get a replacement/warranty or something similar (if still in scope). It could be a hardware defect that just popped up.
Goodluck

It had to have been a virus or corrupt os, I restarted into recovery and flashed it to stock and it works perfectly now with no issues, the button was not stuck internally or externally, as pressing it caused no issues as well as if the device button was stuck it should have navigated the recovery menu if it was stuck. either way after flashing it works perfectly so no it wasnt stuck, and besides i have a galaxy s7 active, trying to disassemble that thing is a nightmare
