Red light flashing.. phone won't boot.

Hello! let's just cut to the chase. I need help..
Couple of days ago I got tired of waiting for the new ota for my phone so I decided to root.. unlocking bootloader went well, installed newest cwm, made a backup of my rom and chose renovate 3.0 as my first rom to try... everything works normal and I update the faux kernel on the rom to version 5b01.. all works normally at this point.. I play games, listen to music, surf the web.. yesterday I then updated the kernel to 5b03.. I went playing dark knigt rises (btw a very good game) and the phone heats up pretty much (which I think is normal as the game is quite heavy and I use wilkyys game booster app). I play about 15minutes and I get the message that the battery is running low, I plug the charger in and continue.. five minutes go and the phone freezes and the screen goes black.. the phone is connected to the charger and the charging light blinks red.. the phone won't start, even when pressing the power key for 10seconds. I can get to the bootloader and recovery _when_ the phone is connected to the charger thou.. if I unplug the charger the phone won't do anything. I search the problem on xda and find some threads about similar problems.. eventually after changing from the wallcharger to the usb charger on my pc (did this many times..) the red light goes solid and I press power and the phone boots normally.. weehee I made it!! or so I thought..
Next day: I woke up and the phone was in charger all night. Battery reads 100%. I load "system tuner" and experiment with undervolting my phone (only -50mv) and run some benchmarks and everything seems working.. I start to download an app from the play store.. the phone freezes and again the same flashing red light is to be seen, I thought it could be because of the undervolt but I'm not sure anymore.. and now I haven't got the phone in working condition.. I have now got the phone in recovery for about three hours and there should be enough juice for it to start but it wont..
I also restored my backup but that didin't help.. with the getvar battery-voltage command it reads about 2500mv which should be enough to atleast power it on?

2500mv is far too low for lithium ion batteries. There are protection mechanisms in most lithium ion batteries that will trigger at 2.7volts or lower putting the battery and its protection circuitry into deep sleep.
From the battery university: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries/
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
If this is the case you may not be able to recover easily. We can only assume something went wrong with the phones firmware that caused it to deeply discharge and now protection measures have kicked in.

hmm.. thanks for the answer.. last night I got the charging light to stay solid when I plugged the phone in and I was so happy.. but I was so stupid and tried immediatly to turn it on.. it even started and got to the quietly brilliant screen, but died pretty soon and the red light started blinking again.. then I realised I should have kept it charging for a while before trying to turn it on... god damn it..

When lithium batteries are deep discharge (below 2.7volt) changes take place which can cause short circuits in the battery, recharging then becomes dangerous, hence the battery goes into a form of safety mode, it's like a fuse blowing. It may never take a charge again, or if it does, the battery life will be less than before.
Hope it recovers okay however if it really did hit 2.5volt it could be permanently damaged now.

mine was doing that for a while. Keep it plugged in, if the wall charger doesnt work hook it up to a computer. it will turn on again...

simple keep the phone on charge for few hours and dont touch it.

Ok back to the problem.. the phone was in charger yesterday for about 12hours.. and still won't show any signs of recovery.. blinking red light continues... I might just have to accept that I have to send it in to repair... sigh.. and I think I have to pay for it..
As I said in my first post I have restored a nandroid backup of which I made as soon as I installed cwm.. so I should be at stock firmware? allthou I can't confirm it as I can't get the phone to boot but cwm said restore was succesful.. next step is to install original recovery and relock the phone, am I correct? so next question is.. is there anyway to do this as everytime I try to flash something with flasboot I end up with "failed: low battery"...?

I've experienced this kind of problem when I drain the battery flat; naturally, I crapped myself like everyone else since there's no easy way to remove the battery like you would for any other phone.
All I did (and still do) when this happens is hold the power button until the main buttons flash white a few times, let go and it should reboot the phone..

two minutes pressing power button, nothing happens

did the buttons even flash??
Try holding vol down + power until you get a response, then try holding the power button again ..
for me the key was to get the buttons to flash white, thats when i knew things were gonna be ok! :highfive:

no response! only response is that when it's in charger I can get to to blootlader and recovery with the vol- power combination..

Tried that :/ won't work.. as my phone doesnt restart with the script.. only way to get a response from it is to press power and vol down when in charger...
Thanks for the suggestion thou.

all right.. quick update.. I have sent the phone in for repair.. so just waiting for the repair bill

Ok... update (don't know if anyones interested..) Today I got at txt message from my carrier that the phone is now ready.. and what do you know.. it was covered by warranty. They changed the motherboard and the screen module (I had one dead pixel) needless to say Im pretty happy now.

Don't you just love it when that happens.
I had a rooted phone and my warranty was probably void. A week ago I dropped the phone screen first onto a concrete floor and I expected the worst. Picked it up and turned it on and to my surprise, the screen hadn't cracked. Used it for 5 minutes and it worked as it normally would. When I got back home and wanted to make a call, the screen wouldn't turn on. The lights for the buttons would light up but the screen would remain blank. Calls and texts would come through so the phone worked, just without the screen. After about 10 minutes of tinkering, the screen turned on and I heaved a sigh of relief thinking all was normal again. But when I locked it and tried unlocking it, the screen refused to turn on again. At this point I assumed there would be a loose connection between the MB and screen.
I took the phone to a few repair shops around here to find out how much they would charge and I got quotes around $200. So I decided to try taking it to the vodafone store to see how much it would cost to get HTC to repair the phone. The guy over the counter inspects the phone and finds no physical damage to the screen and says that they'd be glad to replace the phone right then and there at the price of me losing all my data as that would be unrecoverable. I told him I'd be glad to have a replacement on the spot. So in the end, I guess I got a good deal.

Lucky you !

I had the same problem last night:
phone charging with the HTC wallcharger, alarm set.
the device did not ring: it died during the night.
At first, impossible to boot (rom or hboot) or to charge it. I plugged it on my PC and the red light started to flash. One hour later, it was still flashing, so I tried to turn it ON
It turned ON but repported 2% battery only. (ok, that's why it was refusing to boot)
4 hours later, ON and plugged to the HTC wallcharger (that I verified of course), it was still 2%
After three reboots, plug/unplug several times, suddenly battery displayed 44% instead of 2%
Battery monitor repports that indeed, the device charged for the 1st part of the night, then suddenly and very quickly discharged to 0 while plugged, with no particular app to drain the battery.
During the 4 hours it was plugged and ON, it remained 2%, then a sudden 44% after a reboot.....
What the hell is that???? I've now cleaned cache and battery stats in recovery and I'm letting it charging to see if it goes above these 44%
Weird, I really thought my battery had just died....
EDIT: 2 minutes later, it now repports 46%, so seems to charge correctly. But I need to know what happened, I usually relay on my phone alarm to wake up, and if it happens again, it could be a real problem. Maybe I should flash an other recovery, even if I never had a single problem with it?

I have drained battery, been charging all night with a flashing red LED. No response. Now when I plug it in it still flashes red. When I hold the power button (also power+volume down) the main buttons start flashing white, but no response from the phone whatsoever.
When I let go the power button during the flashing, the lights either go out or stay on..
Any ideas? Thank you!

My Samsung Galaxy Nexus won't turn on

First of all I read all the possible posts here in the XDA forum about this problem but no one was able to help me :s
I was listening music with my cellphone than it crashed and turned of from nohting. My first thought was "Damm, it crashed!" and I removed the battery and after a couple minutes I put it back and than the cellphone never turned on again. No battery status is showing up, no leds, odin and flash mode doens't work either. I don't no what to do :s
I tried this:
◘ Unplug from USB, remove battery 5 min, put it back
◘ Odin and Flash mode
◘ Turn it on without battery on pc
◘ Turn it on while recharging
My GNexus model is a I9250 GSM.

Could you add some more details? How long the phone's been in operation, refurbished?, rooted?, your current ROM, kernel, radios, advanced kernel settings such as voltage changes, any tweaks, battery type, temperature.
This exactly happened to me on my DroidX. I spent 2 weeks trying everything to revive it including taking the phone apart before adding it to the pile and getting my current GNexus Toro.. so I know how much this sucks. I'm not an expert on phones bricking but I know that connections can go bad or come loose, especially if the phone has been dropped or other impact, components start to lose their integrity over time and voltage shorts 'burn out' op-amps. You mentioned listening to music, so I'm wandering about the IVA components burning out, which usually has voltage too high especially on boot... Hope you can get it working.

Well first of all I thank you for your concern and my phone is on again, thanks to my uncle. The phone is '4 months old', I rooted last month, bootloader unlocked and I was using samsung stock rom (4.2.1 JB). Yeah, that really suck monkey b*lls. If you got the same problem as me (I really hope not) that's what you should do: First remove the battery, plug the charger and than put the battery back. In my case, It kind "shorted" the battery and my phone is back on. I was reading posts and posts and discovered that GNexus has this problem and a lot. Dunno when it can happen again but I really don't want a paperweight. Once again, thank you!

Glad you got your Nexus back up and runnning. Thanks for posting back with details after you figured out the problem and got your phone working, +1 right there. There's always a good chance this will help out someone later on. :good:

Confirmation: balums worked for me
balums uncle's solution worked for me: specifically, (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button.
Thanks balums!
Does anybody have technical (design/EE) insight into what would cause this?
This was starting from a device that appeared totally dead.
The battery was *fully charged* (and showed up that way immediately when the device finally booted).
I had done the obvious things of removing/inserting the battery, cleaning contacts, checking the USB power connection.
Was about to pull it apart when I saw balums post, saving me huge time.
Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.
Phone won't boot. Device won't turn on. Won't start. Dead. No worky.
Thanks,
Seth

Awesome! You trick worked, balums!
Interestingly I also have the standard stock version of OS and Hardware which I bought 14 Months ago (nearly to the day). I was surfing over WiFi yesterday evening and when I turned the phone off I noticed the screen getting grey for a moment, not black. And this morning the Nexus just didn't turn on.
Anyway, thanks for the solution, have a nice day!

That is very odd because my i515 also did the exact same thing and I have owned it for 15 months. I can't wait to get home and try this trick. More to come.
Drew

Thanks!

Hey Balums,
My GNex didn't turn on this morning and I was really confused as to why it would do such a thing, until I saw your post. Thanks a lot for posting your uncle's remedy!

Galaxy nexus wont turn on or charge.
I tried (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button but my galaxy nexus still dont turn on. i have 4.2.2 stock rooted. i was downloading something and my screen become weird in colors and i cent use the phone. i turn it of and now wont turn on again or charge.
after unlocking and rooting i installed this touch recovery from google play. [ROOT]Recovery Tools

Excellent! balums' suggestion helped me. I thought I had tried this before but apparently didn't quite get this in the right sequence.
The only remaining issue I have now is that when it does turn on, I've got the thunderbolt on the battery indicator, the phone says it's charging at the lock screen, but when I go to Battery under Settings it says that the battery is discharging. This effectively has my phone in a state where I can't unplug it (battery is too low but it also doesn't appear to actually "charge"). I tried replacing the Micro USB charge port PCB board and came up with the same results. To me, this seems like a problem and may indicate a motherboard or battery connection issue. I used the "Battery Monitor Widget" and it indicated that it was getting AC power. Any thoughts?

Thanks to XDA and Balum's suggestion! I thought my phone just died! It was on 70somethign % battery last I looked, connected by USB to the PC and I don't know if I turned it off and walked away for a while or if it turned off by itself, but it would not turn on no matter what I did after I got back to my desk. It is on Android 4.3 takju stock not rooted.
Thank you all again for the instructions on how to revive the GNex!

Samsung Galaxy Nexus won't power up
I got a Samsung Galaxy Nexus. I got it from my cousin and therefore don't have any information about the rooting status as well as the ROM but i guess it was running stock. The phone won't turn ON, it is not detected in the computer. No LED or any other indication. I tried the above method which worked for many people but it failed. What is special about the phone is that the upper part of the screen is heating up more as compared to the rest of the phone. Can somebody help me fix this? Is this a hardware issue?

I have the EXACT same problem as you do. I have no idea where to start to try to fix it. I took a picture, then lines went squiggly across the screen, then it flickered, and died. I cannot power it on at all. I tried Uncle's tricks. No luck.
Anyone have some ideas on what to try? Thanks.

Also having the same problem. My Nexus has been rebooting randomly for the past week or so, and finally, this morning, it refuses to turn on at all.
It's a Verizon Galaxy Nexus running stock, but it's been rooted. I'm using the extended battery. The trick that was posted earlier in this thread doesn't seem to work for me. I've tried multiple USB cables and power sources.
I'm going to try the standard battery when I get home, but I'm not expecting positive results.

Work-around
About two months ago whenever I turned my Gnex off, it became totally unresponsive to all attempts to start again. After a lot of trial and error, I discovered that if I pulled the battery for 30-60 minutes and reinstalled, it would power on normally. I have completely wiped and rooted the phone and the problem persisted.
Today I thought about it some and realized there may be some residual charge in the phone, and my waiting period is to allow the charge to drain. To test this theory, I powered the phone down and then tried to restart - nada. Pulled and reset the battery - nada. Pulled the battery, shorted out all four pins that would make contact with the battery, reinstalled battery, and it powered right up. I have not been able to successfully repeat a fast restart when shorting out all four pins. Pulling the battery and waiting 30-60 mins still works.
Incidently about the same time, my screen has stopped auto rotating (and yes it is set to do so).

galaxy nexus reboot
my galaxy nexus is about 1 year old now and this is the first time that i've encountered a problem with it. It suddenly restarted, and will take about 5-7minutes before it opens, it will be open up to the "X" logo and when it reaches the normal screen it will restart again. I don't know whats wrong with it. please help/

You saved my Galaxy Nexus

Similar problem + water
Ok, so I have a similar situation I believe. My phone took a swim. I left it off and riced it. Later on after I believed it to be dry enough, i turned it on. (wow it freaking worked) After a few seconds of using the device checking screen the phone snapped off and went into a reboot. I waited until it came back and i shut it down and thought I'd let it go over night. I plugged it in and let it charge (charge icon was displaying). Everything looked good.
Fast forward. Morning time. I go to turn the phone on. Nothing.
This time the phone won't boot. Instead all i see is the white battery icon show up indicating the battery is 100%. When i plug it in to the charger i get the battery with the charging bolt, then it shows the normal battery indicator light. After that, I get nothing.
I tried the method I saw above. remove power, remove battery, apply usb power, insert battery, press power. Sadly it didn't work.
Anyone have any other ideas as to what might be going on?

Xperia S dead?

Hello,
My Xperia S which I bought in August 2012 doesn't boot anymore. A few weeks after I bought it, I unlocked the Bootlader and installed custom Kernels and ROMs and it worked fine all the time. I was on KA 22.1 SSpeed and Advanced Stock 17 and wanted to try something else, so I installed XZXperience 2 and the Elite V2-Kernel.
Well, after that, the phone worked fine but I noticed some heavy battery drain. Charging took waaay longer than usual (full charge about 4 hours with the plug) and the drain was immense. BetterBatteryStats showed me a Deep Sleep of 98 % while I lost about 15 % of battery life in ONE hour, that can't be somehow. The phone however worked still fine.
So I decided to flash the Advanced Stock Kernel again but the drain didn't stop, it was as before. I thought that the Battery Stats are maybe corrupted, so I let the phone discharge itself completely (didn't take long) and wanted to charge it fully. When I plugged in the charging cable, the first unusual thing was, that the red light appeared instantly upon connecting. Normally it would take a second or so. The second thing is, there was no logo, no battery symbol, just nothing but the red light when I plugged the cable in.
I slept a night and after I woke up, I disconnected the cable and wanted to start the phone, but nothing happened. Still, the only thing the phone does, is lighting red, when it's plugged in. Fastboot or Flash-Mode don't work, the computer doesn't recognize anything.
So...what to do? it appeared after I flashed the new ROM and Kernel, but I don't think it has something to do with them...the drain was also there with the Advanced Stock Kernel. Although I must say, that I often had flashing errors, often the device said something like:
format_volume make_extf4fs failed on /dev/block/mmcblk1p2
To me, it looks like the battery has a deep discharge and is dead, but I don't know, what could I probably do before sending it in? If the battery is dead the warranty should still be there, even with the unlocked bootlader, am I right?
Best regards

when you power on your phone what happen?

Ur phone boots while charging,but not charging.If this the case keep ur phone in ur hands for 10-15 min.Enter into recovery while led is pink.Flash other kernel.Else take the battery out charge it,enter into recovery flash other kernel

I can't go into recovery, because the phone does nothing, I can't start it. There's still warranty on the phone, so I'd rather not like to remove the battery...

ok so its no screen at all,
when u pressed power+volume up for 10 seconds does it vibrate?

Already tried, it doesn't...even after holding for minutes.

You could open the phone and disconnect the battery, or let the phone sit long enough for it the battery to die.
This will reset the phone.
Only problem is how long to let the battery die, as there is no way to tell.
Once the phone resets make flashtool ready to flash just the kernel, and use a rubber band to hold the volume down button in.
With flashtool waiting and button pressed plug in to PC.
It should give red led for about 10 minutes then flash.

Well, the incident happened a few weeks ago and after I charged it over night and it didn't work, I left it there for nearly two weeks and nothing has changed so far. In your post, you said, that you had to wait for 51 hours until your battery died but two weeks is quite long I think...
What do you suggest? I think, I'll send it in, if the battery is broken, the warranty should cover it.

Well, the incident happened a few weeks ago and after I charged it over night and it didn't work, I left it there for nearly two weeks and nothing has changed so far. In your post, you said, that you had to wait for 51 hours until your battery died but two weeks is quite long I think...

I would call Sony and get the ball rolling on a warranty claim.
Sorry for your loss, and good luck

Simple fix I think. This has worked for Xperia S and Xperia U. Both phone i brought as "DAMAGED". LOL. Battery is toooooo dead for the phone to detect it..... Use a wall charger to charge the battery up . I used a charger off ebay ($2 including post) that was for a Galaxy I9000 battery (old phone) and used wires and taped them to the battery..... Didn't even need to fully charge it! just like a jump start sort of thing...
Came up with the idea as at work we have to "jumpstart" car batteries to trick the charger into charging them
If you have a DC power source that puts out 4.2v at 350mA +/- 50mA then TRY IT and please let me know.

Well, I have a lithium charger for round-type-batteries, but we're talking about lithium here and if the battery is really damaged, it could be quite dangerous to charge it. The output of the charger is 1A, too, quite a bit higher.
I tried a last thing and took the battery out but it still only shows a red light while charging, so I'm going to try to send it in.

R: Xperia S dead?
IT happened The same for Me...
I was very worried..
I plugged to charge for 21h... Unplugged but Nothing!!
So i replugged iT and watched for 1H.. Suddenly IT Booted(But opened only logo Sony And Crashed!) So i Tried to unplugg and power on the phone but nothing.. No booted!!
So after 25m iT rebooted and like a furet i dropped my phone from The table and like a crazy tried to go in recovery.. So it Gone in Recovery i've Wiped ALL And Reinstalled Fw-Kernel.
So now i'm using The Xperia S

Still not going then??? Might as well order a charger for a couple of bucks off ebay...

All right, I got my phone back from the support, they repaired it and it's working now.

[Q] Problem with battery?

I've been away from the Xperia S forums for about 4 months now, since my Xperia S died. I've been using a Samsung Galaxy S II, but i'm pretty tired of it, don't like amoled screens, battery issues, constant reboots, radio problems and it goes on and on.. SO I want to try to revive my Xperia S.. Here is what happened:
4 Months ago, I had just finished flasing a Paranoid Android ROM (4.4.2 KK) and was setting up the phone, had just finished installing some apps and was testing some CPU Governors, I/O Schedulers and things like that, running AnTuTu and Quadrant benchmarks. In the middle of an AnTuTu bench, the phone just shut down (with about 50% battery left) and woudn't turn on again. When connecting the charger, the LED woudn't light up, the phone wouldn't vibrate, Vol Up + Power wasn't working, coudn't enter recovery/download modes. Hard bricked. So I opened up the phone and removed the battery, tryed plugging in again and nothing, so I left the battery outside the phone for a couple of days. After that, I made a quick "short circuit" with the batter, about 1/2 seconds, and plugged it back in, connected the charger and the phone came back to life. Now I could enter fastboot mode, so I re-flashed the stock .96 using Flash Tool, re-rooted, and re-flashed a newer build of Paranoid Android and everything was working fine again. I managed to backup all my photos and documents, and left the phone charging overnight while downloading some apps from the Play Store. When I woke up: dead again, but this time it's different. When I connect the charger the RED LED lights up, but it turns off after a couple of minutes. The rest is exactly the same: can't enter recovery, can't boot, can't fastboot, Vol Up + Power isn't working.. So I took off the battery and tryed a short circuit again, but this time nothing happend.. The first time the the cables heated up quickly and this time nothing happened. So I don't know what exactly is going on. Is the battery completely dead (2 years old phone)? Or is my device unable, somehow, to charge the battery? If there is no charge at all, the short circuit won't work.
Anyone with any experience or any guess? I'm searching for a new battery so I can test it but it's kind of expesive here, about 60USD. I can't stand the SGS2 anylonger, and I'm not buying any phone until the Snapdragon 810 shows up.

I'm having a similar problem: After installing uCyan everything except the battery drain (irrational jumps in the curve) seemed to work. Then at some point the phone died and now is in a charging (red light, some minutes), bootup loop. Sometimes it reached the sys to then instantly die again. I was able to get into TWRP when I fortunately saw the next bootup. But the battery is too low to get stock or any other recovery back. So everything seems broken. I have tried with two USB cables. The phone/battery is over 2 years old.
If any further actions could help, please let me know. Would also love to revive this phone.

try the rubber band trick from here.

Ok I will try rubber band trick then. I think I already did it two times. I would have liked to avoid flashing the stock.ftf back and then doing again the unlocking, rooting and custom ROM flashing.

I thought You hadn't done that. You don't need to unlock bootloader again even if You flash stock ftf. And if You intent to flash a Kitkat or Lollipop based ROM, then You can simply skip rooting and all and follow the method from here.

z5 premium sudden death

About a week ago, with my battery at 39% i plugged my z5 premium in to charge and it never came back on again.
I have tried all the usual tricks, pwr and vol up, removing the battery, the sim slot button, and pretty much any combination of buttons and still nothing.
It will charge just fine, but will only reach the white sony xperia screen and no further. it will flash up the white screen then go black with the notification light flahing red 3 times and then staying red. once or twice it has started to load the 'powered by android' screen and then just blackness. If i hold vol down and plug into laptop the notification light will turn blue and it shows up as 'adb android device'. Thats the extent of the life left in it.
So what would people suggest as my next step? is it still possible to recover the data thats on the phone or is it a total loss?

I had exactly the same problem over a month ago. I am pretty sure it happened because of liquid damage to my motherboard.
I managed to bring it back to life by flashing with flashtool and ticking ALL wipes and resets available.
It worked fine until it died for good weeks later (I had left it to charge overnight and there were no signs of life the next morning). After a quick visual hardware inspection (aka teardown) I concluded that the only solution was to replace the motherboard. I did just that, and every other component works fine.
TL;DR: Give it a go, flash with all wipes and resets offered by flashtool (you'll lose all data) and hope for the best. You better be looking at prospective phones in case your mobo goes kaput.
EDIT: wow I'm only 4 months too late haha. Pretty sure he has a new phone already xD

If your computer cant detect the phone, it could be one of the following:
- Bad usb cable
- Bad usb charging port on the phone
- Dead battery
- Dead motherboard
If your computer doesn't make any sound when plugging the phone in, then missing drivers shouldn't be the problem and you should troubleshoot each of the possibilities I mentioned.

2-minute reset.
I thought mine was bricked after only 2 months. I came across this fix on the Sony website and it fixed mine where it could work again. I had to factory reset it. It was just locking up and freezing. Be sure to hold that button in for 2 solid minutes. I watched the clock. Longest 2 minutes of my life.

I am just adding a list of similar threads that have been recently posted regarding this strange sudden death issue, battery not charging, weird non-software bootloop.
Sudden Death
InfiniteBootLoop
Unable to Turn On
My Phone Just died (april2019)
Not charging (user is rooted though)
I think i will also collate many of the similar threads into titles and post it as a new thread. As this forum is extremely bloated and repetitive whilst simultaneously being confusing for some users.
I guess Z5P is old now, but trust me the XZ3 is complete garbage so support for Z5P should be much cleaner and better organised now.

Any news for this?
