Z2 Plus Hard Bricked - Lenovo ZUK Z2 (Plus) Questions & Answers

I Was running Lineage OS 17.1 on weak battery (basically on power bank 24/7), now when I purchased a new battery while the old battery was too weak, my phone died on me!!
I went to local repair shop he verified-the power is flowing through charger to battery port but there's a short (Short circuit) on the mother board which isn't letting the phone to boot up (no display nor charging notification light) & the guy isn't kind/patient enough to locate and fix & i see a bleak future now,
Reason for reaching out for assistance is: I have tons of personal data from WhatsApp (not backed up since was travelling 2 days no wifi) to Bank Card details (lost card saved on phone) docs contacts, login passwords with 2FA locking me out of all the accounts sync'd to it etc. Which needs to be recovered.
Update: I checked on my pc it is showing "QUSB_Bulk" upon googling it says my device is hard bricked. Any way to recover my device without loosing data ?

I have replied you here.

Are you talking about shorting method ?

If the deep flashing USB cable method no longer works, shorting test points is probably the last only choice, however use it at your own risk.

I am trying to upload a new ROM to my phone but i am having problems with it being recognised by my PC.
Firewall is switched off on my PC.
USB to PC settings on phone set to prompt me and default to ActiveSync.
PC not finding the Memory Card also as a drive.
Hard-Reset also performed with no joy.
Nothing is happening however other than charging. This is the same on all PC's i have tried.
Any ideas how i can get it working??

If you find a solution, tell me!
Mine won't sync either, no matter what I try, so I've resorted to using a BT USB for syncing/file transfer. I have to flash via SD card and won't be able to use Task29 until it's set up to work via SD card either.

You can enter bootloader and then plug in the usb. This way you don't need to sync with active sync Task29 runs this way.

Nope, that won't work for me. When I enter the bootloader, it says 'serial' in the white portion at the bottom instead of 'usb'. No amount of hard resets clears this up for me.
Thanks, though.

There's good news and bad...
I had this problem, the good news is that I think it's fixed now, the bad news is it involve a trip to HTC. I flashed back to stock and still had the problem, called HTC who agreed it was probably a h/w fault, they piucked it up, repaired it and it's in a UPS van on it's way back to me as I type.
Until it comes back I can't confirm they really have repaired it, or what they've done to fix it.

Thanks so much, Gordon. Please let me know how it worked out for you and what costs were involved.
I'm sure, at some point, I will have to bite the bullet and get mine fixed as well.

I have the same problem.
After all, I find that the USB port of the phone is bad, i.e. some pins are brocken.
After changing the USB port, I solved the problem.

Just to make sure, did you set Activesync to use the slower method? When I upgraded my ROM I had to use the slow method in order for my Windows 7 to see the new ROM.
guys i have the same prob and i bought it from USA unlocked Stock Asian Rom and Now i am in Pakistan.I had some major issues with it.It just stopped syncing one day.Have tried everything.The battery usage also increased dramatically(it dies in 10 hrs after a full recharge)I thought it was a virus but now i think its hardware.I think i'll send it for warranty claim.
I just went through this on my VZW TP2. A month ago it began syncing slowly or not at all, very sporadic, and after messing with it for two hours it began working again. I tried everything except a hard-reset, including reinstalling ActiveSync, changing cables, etc. It happened again earlier in the week and an hour with HTC on the phone couldn't revive it. I called VZW and had a new phone in two days, and we're now up and running again.
I tried BT sync at one time but didn't like having to click multiple times to get it going every time I got within range. There doesn't seem to be a way to have it sync automatically or with one button.
I have the Tmo TP2 and SAME issue, I luckily am getting a new one from Tmo, but I am really starting to think something more is going on here........... I am not convinced ALL OF US, even a lot on PPC geeks, same exact issue? different carriers? come on........... I am glad I am getting a new one, but I would really love to know the root cause of this. IT SEEMS VERY VERY VERY MUCH LIKE THE "TRANSFER DATA" option if "turned off" (if you will), not a physical hardware failure. Kinda like you can turn that option off in windows to not allow USB storage devices to connect, you can still connect other devices (mice, keyboards) or charge things (like our phone) but the computer will NOT see it there at all!!! I really think something like that is happening IN our phones!!! hundreds of us bend the same pin(s). Too wierd.
I hade the same problem!
After trying everything I finally opened up the phone. In the phone I found some dust particles on the usb pins on the board, I cleaned it up and now the sync works again.
NO Sync with Windows 7
I have the same issue with my Win 7 machine...... PC does not even see the Phone at all. Plug it into my Windows XP machine and it's perfect, connects everytime, using the same cable. i have tried everything i can find on the internet and multipal forums, still no Joy! Works great on Win xp, so i think it is a problem with win 7 drivers.....
Still searching for an answer........
Oh, by the way it was working for months, just stopped one day....i even wiped out my pc and reloaded it, no Joy!
I'm starting to have the same issues on my AT&T Tilt 2 but sporadically. Every now and then I lose the phone in MS activesync. I have to delicately place the phone on the table and gently insert the USB cable into the back of the phone in order for it to sync up with my PC. If I move any of the cables or phone, it will drop the connection. I tied several different cables and PC's so I ruled that out. The problem seems to be the USB port on the phone.
Its been almost a year since I've had this phone so I want to get that fixed. If I were to call AT&T and inform them of this would they replace the phone or would they fix the problem with the port and send me the phone back?

I'm not sure what your warranty is from AT&T, but HTC normally has a 15 month warranty on the device. Go through AT&T if you can first. The carriers will normally ship you a replacement device before you send yours in. HTC's repair process is generally very lengthy as they actually repair your device and then send it back to you rather than shipping you a refurbished unit like carriers normally do.
As far as it not connecting, try a different connection method like BirdieSync and Thunderbird. I use this combo on my PC (W7 Pro x64), and it works wonderfully every time.

[Q] Backup contacts after water damage?

My dads phone went in the washing machine, it was put in rice for about 48 hours or more, it turns on but the touch screen doesn't work but menu, home, back, vol up&down and power of course. At first it wouldn't charge and my PC wouldn't notice it even plugged in so I opened it up and there was lots of corrosion on most of the connections on the motherboard so I cleaned them the best I could with 70% alcohol and cue tips and now it charges but my PC still doesn't see it. I am able to get into download mode just fine. It is also a bone stock t-mobile T999, never rooted or anything. I also put his motherboard into my T999 to see if the touch screen would work and it didn't. Is it possible to save all his contacts?
And no sync was setup, but I set it up on his new note 3.
Has your dad ever logged into the phone with a Gmail account ? If so please go to
contacts.google.com
and log on using that account.

No, that's what I men't by no sync, he didn't even have a gmail till made one for his note 3.
Touch Screen may not work but what happened when you put the motherboard in your phone ? Also when you connect to PC as-is ? Does PC show up as QSUB_XXXXX something or none at all ?

Well there was no difference when the motherboard was in my phone, my touch screen wasn't picking up anything with his motherboard. When I plug it in to my PC nothing pops up in device manager or my computer and odin doesn't see it either, this is with it sitting at the lock screen.
I believe, the phone has to be unlocked for the pc to register MTP device.
If it still does not register after that attempt, then you probably may have to subject it to a JTAG although not high hopes. You could also take it to a Samsung service centre, where they can read the memory by other means. I am sorry I am at a loss of expertise in that regard.

Well idk how to "subject it to a JTAG" but there are no Samsung service centre's in Hawaii so I called Samsung and the lady just read some trouble shooting steps after I explained my issue and she was no help at all but I guess i'm just gonna send it in for a 100 dollar refund cause I magically made the red water indicators white again but thanks anyway.
I am sorry to hear that. Ah well if you don't have service centre, then I guess, your options are limited.

When charging phone rebooted and startup PIN no longer worked, need SU access...

Hi Geniuses in XDA!
A strange one for you if you are able to help I would appreciate it. (sooo much)
I was an Apple stalwart for years but got so fed up of them being so inflexible and pushing stupid iOS updates on users every other month I thought an Android Phone would be the way to go.
So many peeps said great things about the S7 so I researched it and after a short while saw that S7 Active would be a better choice than the S7 or S7 edge.
I bought a G891A phone from ebay as a refurb in September 2018, it was in great condition. Worked like a dream MUCH better than Apple stuff. Much faster, brilliant battery life and better everything!
Last week (Thursday evening 28th Feb to be exact) I was charging the phone as usual before sleeping and while holding the phone in my hand and the screen locked - it looked like it rebooted, I wondered why did this happen but no biggie so I left it without the charger connected until the morning.
When I picked up the phone to use it in the morn, the startup PIN would not work which has never happened before.
I carefully entered the PIN - no joy, and again and again, then I tried every different denomination of the same number no joy, then the stock 0000 and 000000 and 1234 and 123456 . nothing still locked.
Buy this time a message came up with the 'you have x tries left until a factory reset' - tried several google searches and found similar issues but not the exact same scenario.
Tried loading progs via the SD card that would disable the PIN or allow the password file in the OS to be deleted but none of these would work as I have the stock samsung recovery and not TWRP or similar so the 'not authorised error' would come up in recovery when trying to load anything I downloaded..
Eventually I just tried the same PIN again until the phone wiped and reset it self - no real issue I thought as I have a current full BU via google drive so I let the phone restore the backup to the phone partially, then I thought what if the backup doesn't contain all the stuff I want? So stopped and disabled google play and put the phone on airplane mode to prevent any further data being written to the phone and potentially over writing anything file that had been given a deletion marker by the filesystem..
I did this as my main method of storing records/notes about many things is via memos. and realised that the goggle drive stock backup does not include Memos or SMS Texts. ( I checked through the entire listing of what was backed up on the google backups)
No I didn't enable the Samsung backup just the google drive one :crying: BUT I WISH I DID NOW!
Anyway you lovely lot - is there any way I can ROOT this phone with minimal file overwriting damage so I can get in the FS and get to the deleted memos and sms texts in the internal memory of the phone and copy them elsewhere using ADB or software or similar?
I refuse to be defeated on this as its not an APPLE!
PLEEZ HALP!!!
Phone is running 7.0
Build is NRD90M.G891AUCS2BQH1
I hope I have been clear in explaining - Need any other info please ask!

Need help installing custom os on dead phone

Recently I dropped my lenovo p2 in water. Since it is out of warranty I went to a local unauthorized service shop where guy opened up the device and let circuits dry. After drying up phone went into a boot loop so he did factory reset. Now problem is that when I boot my phone it can't detect any wifi network and not even sim card. Looks like the antenna is fried. Without net it is not letting me go inside phone by logging to gmail account.
I want some way to install another custom os on device via laptop so I can use it as music player atleast if no sort of network. Touch battery speaker every other thing is fine.
Hope this helps.

SIM card recognized but no service

TL;DR
Moto Z2 Play - XT1710-07
The phone recognizes the SIM card but there is no signal (no service). Tried several things, including flashing a custom ROM. I'm considering buying a new motherboard and changing it myself, but first want to know if anyone knows more about this issue or has an idea/suggestion.
Edit: As an added bonus, something that only now I realized. Now when I charge it, it gets EXTREMELY hot. Like I-can't-even-use-it hot. I used to use the phone while charging all the time, but now I can't even hold it. Seems like the problem is when it tries go past 80% charge. It gets super slow, keeps trying and gets hot. Now I don't know if it's a software problem caused by the various flashings or if it's something that would remain even after swapping the motherboard.
Edit 2: I did a full discharge of the phone and recharged it while turned off. It seems to have normalized the battery problem
Edit 3: RIP. I tried to remove the screen before deciding about buying a new board. In the process, I ended up tearing the digitizer flat cable apart. Now I don't think it's worth it buying both a new screen and a motherboard.
The full story and things I've tried
My phone was working all nice and dandy until it stopped having signal/service. Wifi works normally, but anything related to the SIM card doesn't, like phone calls or mobile data.
A list of things I've tried somewhat in order (both of time and of complexity):
* My SIM in another phone: it works normally, so the problem is not the SIM itself
* Another SIM in my phone: it doesn't work, so the problem is definitely the phone
* Using the second SIM slot
* Changing "Preferred Network Type" between the available ones (4G, 3G, 2G, including Enhanced 4G LTE Mode on and off): this one and the next two items don't really make sense to me, since these options seem to be only related to mobile data (4G/3G internet) connection, not to phone calls which is also not working, but I tried them anyway
* Manually selecting the network: Errors with "Selected network unavailable" and, after trying to register for a while, toasts another error saying "Can't connect to the network, try again later"
* Manually selecting the APN: Tried both selecting between the two options available and manually adding an APN by googling the correct info for my carrier
* Simply booting into fastboot and restarting bootloader: a video on YouTube claimed that it was a temporary solution and that I'd need to do it every time it lost signal. But it didn't even work the first time
* Disabling CQATest and then restarting bootloader (and also clearing its data/cache and removing its permissions): a lot of videos on YouTube claimed this was a solution, including for other Motorola phones. Apparently CQATest prevents the phone from working properly in some scenarios. But I think only when you de-google your phone? Not sure. All I know is that it didn't work either
* Using the phone connected to the wall charger: I think this was another YouTube suggestion, and it actually worked for a few minutes. But I guess it was just a coincidence, as it never worked again
Now for some more... "forceful" attempts:
* Factory Reset: Not sure where I saw this suggestion, but it was pretty much the next logical step. Gathered courage, backed up all my data, etc, aaand... nothing again
* Flashing another ROM: Guess it was here at XDA that I read that it was a problem with Motorola's stock ROM. That, paired with my belief that it could still be related to CQATest being installed, I again gathered more courage to flash a custom ROM. I chose LineageOS and found out that it was no longer supported, but decided to install the last official release. I also read that the problem was the Pie modem firmware, so it all seemed to be going fine since the last official release is Oreo 8.1. I flashed it and BAM it worked! ... for a few minutes and never again. I messed around with LineageOS, tried some of the previous things again, but nothing.
Then, I tried to restore my TWRP backup but it didn't work. So I searched a bit more and downloaded the Stock Pie ROM, flashed it, and closed the bootloader. And then I realized the restore probably didn't work since my backup was made using Pie and my phone was on Oreo. Maybe some files/partitions were missing? Also, when I was creating my TWRP backups, I tried creating a full system image backup but it kept erroring. Only later I realized the problem was that the USB Drive was FAT32 and the full system image was bigger than 4GB. Oh, well, now I know.
So now that I'm with my phone pretty much back on square one, I take it to an authorized repair shop. The clerk said that it was a common problem, and that sometimes it could be solved "by software" and that they'd try that. The other option was to change the whole motherboard, which they didn't do because it was "not worth it" and "almost the full price of a new phone". After two days, my suspicions were confirmed: they didn't fix it with their "by software" attempt. At least I didn't have to pay anything.
When I got the phone back, I put the SIM in again and it showed the icon as if there was signal. But when I tried to call someone, the signal disappeared again. I tried searching a bit more, went through all pages of Q&A here at XDA forums and there were like 3 posts regarding loss of signal. All without any response. On YouTube, I found some videos offering a suspicious .bat file. Upon inspection, it merely erased the modemst1 and modemst2 partitions and then wiped user data and cache. I tried it, nothing to lose. Also didn't work.
Now I'm contemplating a few options:
By watching some disassembly videos, I saw that, when opened, the phone has some parts that act like antennas. I thought that maybe those were not properly connected to the board? Maybe they got dislodged during a fall? Seems unlikely tho, since they are screwed in. I searched for a new motherboard to buy and it's a reasonable price. But I'm afraid it'll have the same problem (or develop it in a short time) since I can't find anywhere what the true cause of the problem is.
Another option is to just give up, buy a new phone and use this one as if it was a "small tablet" lol
So, do you guys have any other suggestions or ideas as to what might be the problem? Maybe a tip like "solder a wire to this spot to create a make-do antenna"? I don't really know where else to search.
If not, thanks anyway for those who read it all
