Z2 plus dead - Lenovo ZUK Z2 (Plus) Guides, News, & Discussion

It was working fine till the failed OTA update.
After a failed OTA update the phone is dead completely.
Unable to boot, or to recovery or to bootloader etc
Attempted QFIL and even that is not working.
A tiny white light is on but nothing else.
Did anyone recover the phone from this problem?
Or is the phone gone forever?

i9506 blue screen problem

hello!
some time ago i talked with my s4 (for 1+ hour)and charged the same time and phone started reboot randomly.
i have tried flashing other FW, bootloader and recovery - no help. tried to update to lollipop.
after that i broke screen (you may understand why).
changed it
Now i tried flashing stock 4.4.2 FW, recovery and csc, but cant get even into recovery, i always get blue screen.
Is there any way to revive my phone? can't find any information about bluescreen at all. is my hardware dead?
Download mode works (only it).
update: twrp recovery works now, i am able to mount usb storage to pc with no problem, tried to copy backup to phone memory-blue screen again. something wrong is with memory. what is possible to do with this?
update2: phone is working. installed stock lollipop, random reboots and sometimes blue screen again. don't know what to do more. please help anybody
update3: internal storage lost. twrp show internal storage 0B. unable to flash kernel or anything else.
never mind. mainboard is probably dead

Phone functioning badly after failed OTA update to 6.0.1

I have a Note 4 and I was very satisfied with the performance until a few weeks ago, an upgrade to Android 6.0.1 was downloaded and applied.
It seems the update failed and despite I'm now in Android 6.0.1, the phone is working very erratic. Sometimes it freezes for a while (10 seconds, 30, 1 minute, 2 minutes) and then just continues as normal (when it freezes for more than a minute, it goes directly to lock screen ). Sometimes it says some app or system process (touchwiz and the like) has failed and sometimes it simply reboots without any reason. I have restarted it in secure mode but there is no difference.
I have uninstalled all downloaded apps but there is no difference. I have reset it to factory defaults but keeps failing.
I have downloaded latest 6.0.1 Firmware from Sammobile and flashed it with Odin but the fail is still there.
One thing I have noticed is when I start in recovery mode (power+home+vol up), instead of the recovery menu, the android robot appears and the text installing update. It goes for a while, then crashes (robot with red triangle) and then the recovery menu appears. This happens every time I start in recovery mode so it looks like there is some update that was applied (since I have 6.0.1 instead of 5.x) but only partially.
Any help?
is there a way to revert it back to Lollipop?
Hi!
Same thing happened to me. Connect to a computer and use Samsung Smart Switch to do an emergency recovery.
But the phone will be erased.
After that, my Note 4 got even better than before!
Good luck!
Tried Emergency Recovery but phone doesn't show up in the list, so I tried Update Firmware. It told me the firmware I have would be replaced by current version (The SAME version) but I went ahead anyway. Firmware was downloaded from internet, phone booted in Download mode and Smart Switch copied the firmware to the phone, then restarted, installing... Error Message: "No Command", nothing else.
I removed battery, rebooted and error message appeared telling there was a problem with firmware update and I would need to use emergency recovery from Kies (I understand I have to use Smart Switch, no Kies). So I connected it again to Kies and opened Emergency Recovery but once again, it doesn't appear in the list. So trying again with Firmware update. If this doesn't work, I'm afraid I have a very expensive paperweight
Failed again. At 25% update, Download screen showed:
ODIN: flash write failure
A window in Smart Switch tells me something went wrong and offers me Emergency Recovery. It also tells me I have to write a recovery code if using another PC. The recovery code is blank. not a good signal.
Again, Emergency Recovery is showing nothing in the list of devices
Ok, I finally downgraded to Firmware 5.1.1 using Odin and the phone is alive again, but I don't think everything is OK. First time I tried to update the firmware with Odin, it failed at the middle of the process, just like Smart Switch did. But second time it completed the process and rebooted. I will leave it as is a few days for testing and if no issues appear, I will allow it to update OTA. In any case, if update OTA fails again, I always can go back to where I am now.
Restarting in recovery mode now shows the android guy with the blue thing spinning (no text) and after a while the fallen android guy with the danger signal and then the recovery menu. That's not what should appear. It should go directly to recovery menu, so I think it is still not 100% good.

please keep posting your observations, i am on the verge of trying flashing 5.1.1 myself.
would be great to know if this resolves our issues.
Phone kept failing also with 5.1.1 so it was not a problem of the Android version. The difference is that while at first phone freezing was the regular thing and reboots were the exception, now reboots are the regular thing, so the situation is worse.
Since it was failing with 5.1.1 and the situation was not better but worse, I didn't wait anymore an installed the OTA update that obviously appeared as soon as the phone booted in 5.1.1
After the phone said it would reset itself, it didn't turn on again. I had to turn it on manually and the the installation began without any incidents. then a new OTA update appeared (this time only ~350 MB). I'm not sure if this was a new update that appeared yesterday or was already applied when mi phone updated to 6.0.1 before the problems started.
So I accepted this update and it was downloaded but then failed to install and the phone told me to contact the repair service.
So now I am just as in the beginning, with a failing phone that freezes and reboots frequently.
I went to the repair service. The guy there didn't know how to fix it an told me to send it to Madrid for repair. But I haven't sent it yet for two reasons. The phone is still under warranty (as ANY OTHER Note 4 bought in the EU), but first, he told me it would take 25 days to repair (this is Spain, you know. In UK it would take 3 days) and second, my front glass cracked so I had to take it to a repair shop to replace just the glass for 30 euros instead of the 200 euros it would have costed to replace the whole (and totally functional) screen officially. So I'm afraid they would find out the glass was replaced and take this as an excuse to void my warranty. In older models you could replace the glass and nobody would notice it, but in the Note 4 you have to break a copper heat dissipation foil that lies between the back of the screen and the metal frame in order to disassemble the phone.

Nokia 5 stuck at boot screen

My Nokia 5 suddenly got stucked at boot screen where it shows "Nokia" in a black background. I haven't done anything like downloading malicious apps/rooting. Just today a system update appeared and I haven't clicked it yet. Its getting hot.
I was using cleanit inside shareit to clean the cache then suddenly my phone hang so I pressed the power button then it doesn't open. After a few seconds it opened and showed that "Nokia" boot screen. I haven't touched the system update yet since I'm not connected to a wifi.
What can I do with this? Non-removable battery and should I just wait for it to get drained or what? It's the global version from Saudi Arabia
Fixed by soft reset
So, I tried to soft reset it by plugging it, press/hold vol up + power btn at the same time. I restarted properly. But still, I don't know why that happened, is it advisable for me to system update?
I have an update this morning and it works well, just update ok. Poor you.
