Boot loop after CM7 & Baseband 15

Hi Guys,
I had a reboot loop problem in my X8 after installing Viber from a Wifi connection and decided to mod it. I successfully unlocked the boot loader & rooted my Xperia X8. Flashed it with CM7 RC1 V4. I rebooted the phone to see the Cyanogen Mod screen with the skate board and it proceeded to ask me a question about the setup wizard or market option, I made a selection and the phone went dead. It rebooted and started hanging on the SE logo. I thought it was due to Baseband 15 and flashed it but no luck.
I have Clockwork Mod on it and can randomly enter it also. I would appreciate any help and pointers, is this an issue due to using the wifi and is the hardware at fault. Once the boot loop starts the battery drains pretty fast I can see the Cyanogen battery status icon and try to wait for it to charge completely
Many thanks & regards

* Did you factory reset it from CWM before installing the ROM? Boot loops are common when one doesn't, particularly if you're coming from another ROM (from what you say, I guess you're coming from stock 2.1)
* It seems that you flashed baseband 015 AFTER flashing the new ROM. AFAIK it should be done BEFORE flashing a new ROM, while still on stock 2.1. If that's the case, you'd have to go back to 2.1 using SEUS (or Flashtool; there are stock ROM images here on XDA), THEN flash baseband 015, THEN root, THEN flash CM7 again.
---
As a side note, you unlocked your bootloader but didn't install a new kernel, which is what one normally unlocks the bootloader for. Unlocking the bootloader isn't needed to flash a ROM as long as it works with the stock kernel (most don't, but yours should.)

Mod issue or battery or hardware fault

Many thnks for the reply mate, what you said is right. I might have missed a few things. But I reflashed Baseband 15 yesterday before your reply to my post and now it seems to be booting into cyanogen mod happily but each time it takes only a few seconds and through a few setup screens before it reboots again.This is exactly what was happening even on the stock ROM before doing any Mod procedure and the battery gets drained too. Could this be a hardware fault.

i didnt get it, when on setup screen you mean when it tells to add your email.....and when you are finished it reboots?!
if i understood well,there is no hardware problem, go to cwm, full wipe-factory reset,advanced>wipe dalvik, reinstall your rom(install custom zip) and it should work:fingers-crossed:

Thanks for the reply stamatis, basically its just shutting down because there is no battery left to power it, it seems. At times it reaches upto the setup wizard (shown when booting for the first time), the next time it could go up to adding a gmail account or language selection screen. I have even seen it load the home screen before it shuts off. This all started happening after downloading some apps from a wifi connection. I have done that before wiping and re installing but will try again. My presumption is that since it was happening on stock ROM and now on CM7 too then it's probably a hardware issue

ok i see now,your problem is battery drain,
is it that extream? i mean, you charge to full and when you open it up it shut down by low battery?
have you try to opening while charging?is it the same?
are you sure its charging?
that way too xtream to be software problem so its more likely that its hardware...

yes you got it right. I do charge it fully and when it boots the CM7 UI for a few seconds the battery goes down half or even less or nearly empty. I have tried opening it while charging and thats when the above happens, yes I can see the Cyanogen charging icon. So you think its a hardware issue and I should not pursue it further

yea, i guess your battery almost dead.....and i dont think its a good idea to by new battery, you better buy new phone,as the batteries are quite expensive if you think that the worth of the x8 right now would be 50 euros....

Help! Hard Bricked Note

After being careful on flashing ROM based on our valued friends instruction, my Note got bricked somehow.
Rom installed: Slim Beans 4.3 build 2 with Raw kernel R4.
Everything works fine and smooth until on time, when i was using the phone with 19% batt while charging the phone hang. It was not responding at all so i pressed and hold the power button until it power off. Then i removed the charge and change the battery from a spare fully charged batt. Now the phone won't turn on.
Note won't go to recovery nor download mode. Does not show that its charging as no charging icon show up. I have an external battery charge though so i'm sure that my spare battery is fully charged. I tried to blindly perform the download mode and connect to PC with Odin and its not recognized. Even tried the one-click unbrick but would not recognize the phone. Any idea what else i can try beside using USB Jig or JTAG?
I’ve read about sudden death issues or reserve battery being depleted but non of the solution worked.
Anything else i might have failed to try? Any advice is greatly appreciated.

No GT-N7000 screen also?

Yes, nothing at all. it just died on me all of the sudden. I've never experienced even boot loop since flashing almost all sorts of ROM & kernel since CM 9 days, even jumping between TW/ASOP/CM/Miui roms. I've always been very careful in following the instructions reading since rooting my n7000.
now this happened. :crying:
Edit: And now i've read that they are about to release a Kitkat Omni ROM..

If there is no response from the phone at all.. then there could be board issues.. Try with a jig if possible. may be that can force the phone into download mode.. else repair center..

Yeah, that's my last resort. No choice then but have the board replaced.
Kitkat Omni ROM out!! I guess my flashing days are over.... for now... :crying:

Hmm.. I was looking to flash the same kernel with the new tech. Maybe look for help from the developer? On his topic was a guy who had the similar situation.
Looking to hear more from you on this.
ps. flashed the kernel once (r4) and the backlights were turning on and off (in settings were turned off), so i figured the kernel isn't supported. Slim Rc2

Well, i finally got a usb jig today and tried it on my n7000, it didnt work. Still no download mode for me, nothing. As i suspect this is already super bricked due to damaged mainboard.

The screen won't light up at all? When you are in a dark room, the screen isn't completely black, and that is the sign you need. It could be messed up partitions. Have you used pit file before?

Yes, won't light up at all not even in a dark room. I have not tried using a pit file before but would love to try it. The problem is i can't get it to download mode, not even with a jig. Tried connecting PC with Odin running thinking that i can do it blindly even without anything showing on the screen. The problem is that Odin can't recognize it.

Having trawled the net for a solution to this, i am interested to see if you have any luck with this, as my note did exactly the same yesterday, although mine is stock.
Completely gutted:crying:

[Q] i9000 screen waking itself constantly?!

Recently i put cm11 on my i9000 and now the screen is constantly turning on. As soon as the screen lock is turned on, the phone wakes again.
Sometimes this happens indefinitely and sometimes it only happens once then the screen will sleep after a second press of the lock/power button.
The only consistent thing appears to be that when the lock screen is unlocked the recent apps are always shown.
I've tried formatting/wiping and different night lies and the m4 snapshot but it all happens exactly the same.
Any help would be greatly appreciated.

use this and see if it's the rom or an app that's keeping the phone awake http://forum.xda-developers.com/showthread.php?t=2179651

Thanks, I've installed this earlier today and I don't quote understand it.
According to wake lock detector, under screen wake lock, running and usage, phone - system (radio) is number one.
Does this mean it's the rom keeping the phone awake?

Not sure how wakelock works to be honest but I don't think it's the rom that's the problem, it sounds like its the radio (modem) try flashing a different baseband for your region and see if that fixes the problem? http://forum.xda-developers.com/showthread.php?t=1870460 http://forum.xda-developers.com/showthread.php?t=1158783

Tried several different radios without any success I'm afraid.
Just tried flashing stock JVU rom and then back to CM11 without any success. Exactly the same issue.
Oddly, if you hold the home key whilst pressing the lock key, the screen turns off and stays off for a while, then wakes after a minute or so again.

New Method
Try going into settings>Applications (or Apps)> Running and check which application(s) is taking up the most memory, it may be that a application from an unknown source is waking up the device, like a virus or your phone is consuming too much RAM. If this is the case try and delete it or run a security scan from the play store such as BitDefender.
Another option is to run a more stable version of CyanogenMod instead of a Nightly, I had problems with Nightly builds and changed back to a stable build. Try the new 4.4 snapshot of CyanogenMod, it is more stable. DOWNLOAD from the official cyanogenmod website, don't update using the option in settings as it always sends my phone into a boot loop. Hope it helps

Try another ROM
Let me know if switching to another ROM helps. I'd suggest Paranoid Android or OmniROM.
The thanks button is right there! just saying...

No luck unfortunately, I think I've narrowed it down, and the menu button keeps activating itself.

Have you erased each and everything? /data and stuff? also, just see if Touchwake is enabled by any chance

I don't mean to drag this old thread back up, but I've come to use my i9000 again as a backup device and it still has this same problem.
Is there anyway I can prove that it's a button that's faulty (for instance)?
I thought maybe a logger that would show if it detected/logged the home button being pressed when I notice the screen turning itself on, but I can't find such an app.

[Q]Suddenly shutdowns on MI3 Need help

I'm using mi3 with Euphoria-OS 0509 version. My phone will suddenly shutdown itself even the battery is full.
I tried re-flash this ROM, but no help.
It happens every time when I use the phone in no time. But It won't happen when charging.

Maybe there's a problem on your phone's battery. Try to bring it on a service center.

What do you mean by "suddenly shutdown itself"?
Do you see 1) the closing down routine? Or 2) does the phone simply not respond to pressing the power button?
If it's 2), plenty of ROMs exhibit the "screen OFF death", where the phone is actually still active but you can't get the screen to light up. try flashing another ROM. Paranoid Android is the most stable ROM for me.
If it's 1), still try flashing another ROM, and it it is still closing down, it's a hardware issue (hopefully battery), so service centre time.

In my case, my phone's screen will suddenly frozen while I'm using, and turn off itself. I need to hard reboot the phone. I used flashed this rom few months ago and change to PAC rom, no such problem until I flash this rom again, all roms were clean flash and the battery was calibrated. So I think it might be the hardware problem.

Well, if the phone was OK with a different ROM, that implies your current ROM is the problem - try another one.
I recall having had the same behaviour in the past, when I was trying a lot of ROMs in quick succession - so I don't know which one(s) it was.
All the same, it doesn't sound like hardware/battery. Make a Nandroid backup in recovery, then flash eg PAC ROM or Paranoid Android - wait a day before adding all your apps etc - and see if you get that issue again.

OK, I got some conclusions, and it might be a hardware problem.
First, I replaced the battery with same ROM, it still got SOD.
Then I flash Omni, PAC, Euphoria-OS, all got SOD like before.
So I return to MIUI, no SOD, but I got random reboots and sometimes Wi-Fi will disconnect itself even in its range.
Now I'm using Ivan's AOSP, still got random reboots and Wi-Fi problem.
And now I need this phone to work because I don't have a backup, waiting for new Nexus!!

Huawei P9 switching itself off

Hi ,
I'm having an issue with my P9 regularly switching itself off.
I unlocked the bootloader, installed TWRP and then flashed Resurrection Remix Marshmallow For The Huawei P9. It's an L09 version. I have installed the current stable version :- ResurrectionRemix-M-v5.7.4-20161118-eva and I'm running open Gapps - arm 64 6.0 Pico.
https://forum.xda-developers.com/p9/development/cyanogenmod-13-huawei-p9-t3500551
Has anyone else experienced this issue or can advise on a fix?
Thanks for your help.

In what conditions it turn off? in standby when screen is off? when you do something specific? when phone use heavy apps?
Did phone had some damages? it fell off? do you use original charger?
I had similar problem when I was taking my P9 from pocket and it was rebooting... turn out that case that I used had a bit more material near power button and volume, and when i was sitting it sometimes hit those buttons forcing rebooting :/

Phone switching itself off
It's switching off after a call, in standby mode and during a call.
Thanks for your help.

First I would report it to Author of that ROM.
Second, Author mentioned that ROM require fix. quote:

Did you used it?
Also if that problem didnt occur in stock rom before.... its ROM problem and as I said its would be better to send PM or ask in that thread for solution for it.
If you have time, you could revert to stock rom, check if it work, then install that ROM again, and check if its reboot itself.
