i've tried using baseband switcher but still the problem exits and no one working on this issue this issue is persisting from 2 years but yet it has no solution.but if u full flashed stock sbf u'll get rid of this but u can't go to custom rom then

Official sbf do fix it. But it has problems of reboots. I think their is a hardware defect
Bcoz in official reboots happen to avoid connection error.and in custom rom reboot don't happen and hence connection error
I m fed up with this problem. Going to service center tomorrow.

Does going to service center solve your problem

It was a faulty device. Returned it back to Infibeam. Hopefully I will get my new replacement tomorrow.

help me with this!

Dude you can do one thing just flash it with the full stock sbf and you'll get rid of the MMI error but there will be a new problem that your phone will reboot very frequently again and again many times in a day if you are okay with this reboots again and again then its fine but if you want to get rid of this then do one thing take it to the service center i hope so they'll not go deep and fix your phone. you just say them that its crashing all the time if the odds are even then you'll get your phone fixed or else they'll say you have void you warrentty i'm gonno try this now because there is no one helping with this

ok dont know if it will work for you but it worked for me
add comma (,) in the end of the code
example:
*100*2# into *100*2#,
works for me

[Q] HELP: my HTC Desire reboot/freeze/hangs when I use a cooked ROM

Hi guys:
I am really desperate now... my phone only seems to work with the official ROM, everytime I rooted, and installaed a Cooked ROM (GB ROM) very soon (in a minutes of using it) it will hang or freeze or reboot.
I explain all backround:
1. firstable I have my desire working for awhile with many cooked ROM (Froyo), after months,the phone started to reboot everytime, so I have sent it to the SAT, and they changed the motherboard. and give it back to me.
- The new motherboard is
PVT4
HBOOT 0.93
MicroO 0,51d
2. I rooted it OK (using unrevoke methos)
3. Flashed a cooked ROM => then is when the problem starts, everything after falshing is OK, but after a few time of usage with the cooked ROM, then the phones starts to freezes randomly.
some further info:
- tried with Neophyte ROMs Reflez 2.0.9,2.1.0...2.1.6 => same issue
- tried with LeeDrOiD V2.5.0 FINAL | 28th May l Official => same issue
- tried with LeeDrOiD GB 3.0.6 => same issue
if I go back into the offical ROM (by unrroting method) using the "RUU_Bravo_Froyo_Vodafone_UK_2.33.161.2_Radio_32.49.00.32U_5.11.05.27_release_157522_signed" => Issue is NOT reproduced!
- In all cases, I did try to keep ONLY apps coming from the flasehd ROMs, to make sure any app is causing the issue.
- I have tried using another miniSDcard (8GB class 4) => same issue!
Is it anything wrong with the new motherboard?
Is there anyway to check logs or trace why is freezing?
Any clue?
Thanks for your advise!

I have the same problem. I have noticed that most times my desire freezes when I download something over mobile network. So maybe the problem is in A2SD? I'm going to try with Cool Kingdom Rom, because I already have EXT4 Partition.

Thanks a lot Deivino for your comments.
Please keep me posted about what happens with your "Cool K. ROM"
hope your issue is gone then.
Mine still present, I can use ONLY the official ROM.

So I had no luck with Cool Rom. It still freezes, but much less now. Also these freezes are very random now, mostly when screen is off. I haven't flashed jet the newest radio and ril, but I don't think it would fix it either. I was thinking about unrooting, but when I did, I got less than 30% battery error with full battery. So I have no idea how to fix it or what is even causing this freezing.
Hi Deivino
Since I've unsuccesfully tried with many cooked ROMs, finally I have decided to take the phone to SAT, which fortunately still on guarantiee.
Let's see what do they find...
good luck with your phone,
best
I managed to unroot my desire and now running official android 2.2 what htc provides and the problem still occurs for me. I don't see no other way but to send it to warranty.
Hi Deivino
I did the same, actually many things unsuccesfully as you see in my first post.
Finally, I sent it to warranty, and they gave me back already a new device!
Now, it works OK.
So, unfortunately, the issue was not fixed at all, either I don't know what caused the issue.

Try cyanogenmod.. it's THE singlemost stable ROM you can install on your phone. Never fails.
I agree.. never had an issue with CyanogenMod ROMs

Hi Guys,
thanks, finally I sent my desire to SAT, and they gave me back a complete new one!
So, with the old one I did all in my hands unsuccesfully as I explained in my first post, so I didn't try CyanogenMod ROMs therefore I will never know if it would works!
Anyway, thanks a lot guy for all your suggestions.

[Q] My DHD keeps crashing and rebooting, but only when the screen is locked...

Hello!
For some time now my phone's been rebooting itself completely random it seems. I just got it back after sending it away to get this issue fixed. Obviously the "repair" didn't really do anything at all. All they did was to flash the latest software apparently.
I got quite fed up with the crashing and rebooting stuff, and figured that it wouldn't hurt to try to flash a custom ROM, in this case I chose to root the phone and try MiUi. I had no clue wether it would solve the issue I'm having, but I figured it was worth a try. So i rooted the phone and flashed the latest version of MiUi (1.11.18).
At the start it seemed like it had worked, and had stopped the phone from crashing. But after some time I realized that the issue is still there, only difference now is that it ONLY crashes when I lock the screen with the Power-button. EVERY SINGLE TIME I do this, in a matter of minutes it will either reboot or just turn black and totally unresponsive. Only way to get it on again is to take out the battery and put it back in.
This is starting to annoy the **** out of me, so I talked to my brother for advise this morning, and he told me to wipe my Dalvik Cache. So I did, and nothing changed, the phone keeps on living it's own life.
I have absolutely no clue what info you guys might need to help me with this, but I'll start with this:
Phone: HTC Desire HD
Android-version: 2.3.7
Kernel-version: 2.6.35.14-cyanogenmod-g319b6e2
ROM: MiUi 1.11.18
Also, the motherboard's been switched once, cause of another issue that is now gone.
ANY help is appreciated, I just want to be able to use the phone normally!
EDIT: Also it seems that the phone won't reboot or crash whenever it's charging.
Sounds like a hardware/software issue your best bet is getting a replacement and re rooting .

no service on gio

i flashed the CyanogenMod 9.0.0-RC0-GT-S5660-GalaxyICS-KANG-beta5, everything seemed to work fine, then i noticed that i wasn't getting any service at all. i then tried cyanogen 7.2 and same story. 7.2 is letting me make 911 calls unlike the ics rom.
can anyone help me pin the problem down and fix it? please and many thanks
i'm now in an endless boot cycle...
is there a guide to just to back to stock?
Flash stock rom via Odin if u want
@wiwid_colgate
Galaxy Gio S5660
#GalaxyICS
it was a supposed stock oden flash that caused me the never ending boot cycle
Odin does not reformat the /data and /cache partitions. Which would cause bootloops on a stock kernel that doesn't know how to handle ext4.
Use an RFS compatible recovery. Otherwise dd back empty RFS partitions back into place.
i had some problems with setting other launcher than adw on default. next time i'd restart the phone it got stucked at samsung logo. So i didn't set my favorite launcher on default and problems were solved. maybe it'll help.
For me the same prob. no service with CyanogenMod 9.0.0-RC0-GT-S5660-GalaxyICS-KANG-beta5 and cyanogen 7.2.
After that i flash with "S5660XXKTI - SER" (One Package-Android 2.3.6 Gingerbread stock)with odin and it runs like a train....(not like the dutch trains)
Do a full whipe before and after flashing.

lol. that sentence has to be explained for people outside of the netherlands...
our train service is well known because of not driving trains when it freezes, a bit. like -10 degrees and ''wissels'' the things that make sure a train can move from railroad to another railroad, something like this..
we know much about water and dikes, but not about trainrail.
lol

You can try another stock firmware go back to 2.2.1 Froyo or 2.3.3. Gingerbread.
And don't forget to select Wipe data/factory reset before and after flashing.
Check if everything is working,if so than flash 3.3.6.
More i really don't no.
Maybe it has to do something about the "radio" you can found out by search here on xda.

kernel panic no download mode.Help :(

so i flashed the official marshmallow for lg g3 on january. everything was fine. today the phone just stopped working. i had no previous signals like glitches or bugs, it was perfect but now its just gone.
so after this 3 months of usage, while listening to music, the phone stopped working (without even touching it)
if i reboot it, it gets me into a boot loop and when it doesn't its just black screen
SOMETIMES THO i have the luck of it booting but i cant do nothing as it constantly shows android.process.com stopped working (i dont remember the exact name) but anyway after 1 minute it reboots himself because of the constant crashes.
if i enter download mode i get a message that sounds like this:
KERNEL CRASH!
demigod crash handler: kernel crash!
*something about dload mode and get ram dump*
*here info about phone like revision and serial*
internal error: oops: PREEMPT SMP ARM
linked in: texfat(p0)
*random numbers*
*error codes*
Kernel panic - not syncing: fatal exception
sorry im so vague about it but im writing this from memory right now. if you need more just ask
as a matter of fact, the only thing that this phone has is the MM official rom flashed (poland one)
its not rooted neither with custom recovery
i still have one year warranty, if i bring it to them its ok or i have to pay? i say this considering mm hasnt arrived yet to my country through ota. the main thing im concerned is if i can recover any of my photos/videos/music as it has some sentimental value but its not a must, the main priority is to get the phone working
and also the phone is recognized as lg g3 when plugged in computer, put cant enter download mode because of the reason above.
no recoveries as i said, and im pretty sure that if i get somehow to factory reset it will stay the same as the kernel doesnt get reflashed (im not a pro, just intuition, correct me if im wrong)
any help is appreciated!thank you in advance
just if anyone gets this problem and doesn't know how to solve it, its a hardware problem, not software, so warranty does cover it
As they won't give me much details, the only thing i know its that a specific component from the phone stopped working
does anyone have an idea of what component from the phone is responsible for that? just so i have an idea of what happened.

SM G928T Update problems

Hello Guys,
This is my first time posting on xda forums,
I rooted my Sm g92t from t mobile,
everything was working fine until i tripped the oem unlock,
restarted the device only to be met with frp block.
searched online and tried to fix it, got it to work
but ended up with unknown baseband and imei null.
Things i've tried
1. Run several roms, all stock
2. tried to use z3x tool to fix but no luck,
3. tried restoring efs backup, no luck since i didnt know much about efs folder by then.
One funny thing is that, whenever i run a new rom,
installing system update which comes up the rom has finished loading doesn't
reach 100%, it gets to 32% and switches to erasing and continues to boot.
I've lost hope, no T-mobile or Samsung service centre close by, i really need help.
