Umidigi Z2 Special Edition - Android Q&A, Help & Troubleshooting

I recently purchased this phone coming from a Moto G4 plus(which was a year if hell)and cost to performance, I'm very happy with it. It came unlocked
and is one if the only phones I found that works both in GSM and CDMA networks. I have not rooted or unlocked the bootloader as of yet and it's running on Oreo 8.1 which updated itself OTA upon first boot. The cameras front and back are very good(better than the Z2, same as Z2 Pro) and I could ramble on about it's specs but this is not the place, I don't believe.
My question is this, I've noticed that it came already encrypted or at least that's what it shows in settings. I haven't yet inserted an SD card since I'm using 2 sims and I don't know if that would make a difference or not but I wanted to see if anyone here is familiar or has run into this kind of thing before?
Please let me know if any more info is needed and thank you in advance!

[Q] Cracking unlock bootloader allowed : no to Yes.?

Hey,
I have recently bought an Xperia Z ultra, and when i was about to CM11 it, i found out that the boot loader unlock allowed is NO.
Now where is live, i brought the phone through and import shop. so the procedure to obtain a operator key and send to Sony is impossible.
I can access my fastboot, i have even rooted my phone, but i really want custom roms and kernels to be an option.
I know that the usual answer to this is that its impossible. But i would appreciate if we discuss it to progress on this as i have seen too many people with this issue and i think it needs a solution. I would request the admin/moderators to keep this thread alive.
Now does anyone know why is it impossible ? is it hardware or software ?
any directions or people that i can personally request to work on this ? any leads ? i am really desperate, i really cant afford to spend that much on a phone again.
is the Xposed Framework any possible solution for this ?
any ideas information is helpful......
There is no solution, or one being worked on that I know of. In one thread it has been asked and a very good hardware hacker said that even taking the back off and putting a Xperia into it's maintenance mode you cant unlock a BL for these locked devices.
Have a read of the hard brick thread for the details
there seems to be a way, just a thought.
Upon on reseaerch, i am finding out a Linux command called kexec seems to be favour here. Since it can bypass kernel and force a custom one...

Kexec for the ultra itself

Are there any developers I can call out/plead to regarding this matter?? its really frustrating to have this much of a powerful device and not play with it. I miss CM.
unlocked bootloader if it says no
I had no idea that the sony z ultra had some units that couldn't be unlocked. why would sony do this, it says being able to unlock your bootloader is important to sony. They even gave me an unlocked code from their site. I bought an factory unlocked phone, so stupid that this one here can be unlocked and that one can't. so am I stuck with a locked bootloader now? I sold my Lg because of this crap now I am dealing with it again ****

It's your carrier that has locked it (Rogers, i'm guessing?). There are only a couple of carriers that locks down the bootloader, like Rogers, O2 (i think) and another one that we're aware of.
It was bought factory unlocked from store no carrier involved which makes it even more crazy. I guess I will sell this model and get different one. Does the gpe have this stupid restriction on its model. I really like the 6.4 inch screen and don't want to go down in size. I am already going to get the nexus 6 so I definitely want a z ultra also

It's shouldn't be locked. Only a couple of carriers locks the bootloader. The GPe's bootloader is unlockable.
@BrownDog99 type *#*#7378523#*#* and check if you haven't. I don't think I've seen a factory one they is bootloader locked. What model? And from where did you buy it?
Ya i tried that it says no bootloader unlock. I bought it from a used cell store in toronto. It has a factory unlocked sticker on it, with no carrier apps installed or anything. Maybe it was a carrier phone, weird it came factory unlocked and with no carrier apps installed. I rooted it and put a dual recovery for lb and of course installed xposed. No custom kernel for me I guess. Too bad. I think it is Rogers and Bell that lock down the bootloader. I am impressed with the speed of it for a 800 snapdragon.

Does the Verizon Moto E have root and roms?

Just bought the Verizon moto e at best buy and have it working on t mobile but want to install custom roms.
Sadly it does not. Just bought mine today as a secondary device.
I am just hoping that someone can do something to unlock that bootloader (could the stagefright vulnerability be used to do some things since it does have some root capabilities?) or at least get the device loki'd.

i bought it for the same reason at best buy to uses as a backup for myself or a friend of family member. Just like you i was curious about rooting and custom roms for it. Sadly i found out by trying to follow the tutorial to unlock the bootloader and when i went to Motorola website for the unlock code it said my device couldn't be unlocked :crying:
Before i picked up the Moto e i seen on XDA the Verizon variant could be used on any service so i didn't even think twice to see if it was unlock-able before trying.
Just now wile typing this it actually got me thinking and the thought of the Verizon variant being able to be used on. got me wondering.
Under the hood of the Verizon Moto e is the hardware exactly the same as the other variants or are there more radios for the Verizon network? I ask this because if its the same would there be someway to install the international variant bootloader on the Verizon variant and then unlock it?
if that sounds very stupid im sorry lol. I don't know very much about unlocking devices besides how to follow tutorials of how to unlock a device. But i do know how to flash and install things im kind of a flashaholic thats one reason i looked to unlock this device right away
Verizon as is already annoys me by how there devices have locked bootlaoders thankfully someone found a workaround for the G3, but seeing how this is a prepaid device that customers pay in full for i don't see why they have to lock it down...
$9.99 from bestbuy, it's the best budget phone. I made it work under t-mobile.

Can't overwrite the bootloader since it is locked, the partition is locked to read. However, I was thinking, since it has that 5.1 update, it must've written to the system partition and which case I wonder if a fake update of some kind be used. Kingoroot also somehow can mount and write to the system partition through their rooting process, if someone can figure how it does that, there is hope for this version.
There is also the possibility of someone developing loki for this phone too, which would bring at least some custom action to this.
Verizon does some weird things, both it and AT&T, I just don't understand them. AT&T locks down the device and sometimes they even get updates that were released for the phone. Verizon declines other phones which people want. Anyways, we only paid $10 for phone, couldn't say no to that, right? Unlocked SIM and if they do find a workaround, just cherry on top of the icing.

+1 - cant beat the price.
With so many of these out there now, I think its only a matter of time until someone figures out the bootloader and rom questions.

I hope so, would really suck to stay on 5.1 and miss out on any security updates, etc.
But from the looks of scanning through part of the forum, no seems to be taking on the task of figuring out a way to do so. The one guy that was trying had school that took over his time and then there are no other threads about it.
Yeah, I hope that you are right that all these new devices out there will spark something.

Noob Question: Dual SIM

I recently bought an unkocked Tmobile OnePlus 7T Pro and a replacement dual sim tray. I'm using Tmobile and SimpleMobile. I believe SM roams of the Tmo network.
The phone does not recognize the second SIM. I have read on the 7 Pro forum that the phone needs the "international rom."
I've tried searching here but haven't had any luck. I'm very new to this stuff, can someone point me to the thread/guide/download for flashing my OnePlus 7T Pro, so I can use my phone?
Just spent $500 on this phone and if I can't get it working, I will have to sell it and find another. Would really like to stay with OnePlus.
Really appreciate any help you have to offer, thanks!
If anyone knows that this is not possible, etc. feel free to let me know. I'm trying to find a different phone that supports dual sim, since my OnePlus seems incapable.

Gonna be a little technical here. Going off the way my 6T works because it's somewhat the same. I have a TMobile branded 6T it doesn't support dual SIM out of the box while being on tmobiles version of OOS also it only comes with a single sim tray. I was able to convert it to the global firmware straight from OnePlus after unlocking the bootloader and installing TWRP and utilizing a tool called MSMtool which is basically the Holy Grail of restore tools. Anyway with being on global firmware I now have support for dual SIM all I would have to is buy a dual SIM tray. As for the 7T pro (I'm guessing McLaren edition with 5G as that's the only one TMobile sells) I'm guessing it works the same way TMobile locked out dual SIM on their version of OOS and shipped it with a single sim tray.
However we did just recently (as in the last couple of days) gotten a working MSMTool, nobody was really experimenting with the device because if you screwed up there wasn't much you could do, now that we have an MSMTool it should make it a lot less of a risk experimenting with the device and seeing what's possible. As for the global conversion for this phone I'm not sure how it would go due to the whole 5G stuff it's possible we get a global conversion akin to the 6T but there's a very strong possibility of losing 5G support (at least I would assume 5G bands in Europe are not the same as the US).
I'd say if you can wait to give it a couple of weeks to a month and see what develops I have a lot of faith in the devs that work on the OnePlus devices. There's also a dedicated forum for the McLaren edition now and I've been reading around about everything.
I apologise if I'm coming off like you don't know what any of these things are I'm just trying to explain it the best I can.
Hey, that was a great explanation. Thank you!

No problem homie anytime, I would highly suggest holding out and seeing how things play out, it's a fantastic phone (currently have my 6T but plan on upgrading very soon to the 7T McLaren) I have very high hopes things will turn around for the better very soon. If you have any other questions feel free to PM me I'll help out as much as I can.
Thanks! I love the phone but returned it today, as the dual sim is a crucial function for me. Once I get the $ back I might get the international one, or maybe a Samsung S10 or Huawei. Been using OnePlus for a long time but it may be time to move on haha

Suggestions Needed on Rootable Phones

I am currently a customer with Cricket Wireless. All of their phones come with the bootloader locked, which I didnt know when I bought my E5 Supra a couple of years ago. Last week I plugged it up and it started smoking randomly. It's fried. I did a good bit of research and decided for under 220, the Moto G7 Power used off Ebay unlocked was my best bet. I made sure it was rootable, I thought.
The seller had it listed as "Motorola G7 Power Unlocked ATT/Cricket". What came in was a Verizon variant (XT1955-6) that had not only a constant error that I wasnt using a verizon sim but had a locked bootloader. The error thing, I could live with or fix. I was on the phone with both Motorola and Verizon with the hopes I could sweet talk them into something, explaining I was an app developer.
Well, im sending the G7 Power back. I was going to get the XT1955-5 which could be unlocked through Motorola or the international version and just flash whatever bands were needed. But at this point, I think I want to steer clear of Motorola altogether. Everyone in the G7 forums is constantly bricking, some hard bricking and actually sending them back.
Models Im Considering
One Plus 5T
LG G7 ThinQ
Samsung Galaxy A50
Samsung Galaxy S8-S9 (whichever I can find for that price range)
Samsung Galaxy Note 7 or 8 (whicheveer I can find for that price range)
Sorry for the background but, does anyone have any advice or recommendations on what a good phone with an unlockable bootloader for under $220 would be? (used is fine) I dont even really require it be sim unlocked, so long as it doesnt have a locked bootloader. I see the Pixel guys ran into issues with bootloaders being locked so that ruled that out. Im not too concerned with camera or anything like that. Mostly freedom to do with it as I please and a smooth processor lol. Thanks in advance!!

Xperia 1 64GB 802SO, can't update Android, any ideas?

Hello, just got a Xperia 1 64GB 802SO (SoftBank) imported to Canada. I can't seem to get any Android updates. Its stuck on security November 2019, and Android 9.
I've tried starting the phone in Japanese with Japan as region and using a Japanese VPN.
Does anyone have any ideas on how to trip the updates? I'm stuck.
Thanks in advance
Hi. I have the phone. But I'm in Japan. Is it bootloader unlocked? If it is you might not be able to get ota Updates
Hey there,
No need to stress, just download the Xperia Companion app for Win/Mac and you can do all the updates from there for that japanese version regardless from where you are located.
The updates are not accumulative, so you will need to do one at the time. Can be a little bit time consuming but very worth. Kindly let us know how it went.
TrustAugustus, I just have regular Android installed as from factory. For some reason the updates didn't want to come in. I can only guess it has something to do with my region, Canada. Some sort of region lock on updates... However I installed the Sony PC Companion app as djmaxi suggested and I was able to finally get the updates to come in. I was able to update from 55.0.E.0.528 (Android 9, November 2019 Security) to 55.1.B.0.335 (Android 10, August 2020 Security).
djmaxi, thanks it worked. It was just as you said, one update at a time, but it finally updated. I'll have to check periodically thru the Sony pc companion app for future updates. Sony customer support wasn't able to help me with this even. Thanks!
Any issues with the japan version
Hello
I am planning to buy the japan version as well, just wanted to know have you faced any issues using this one in Canada except the update issue which you mentioned.
aliadils3d no other issues so far. I highly recommend the phone. 4K HDR video looks amazing. No camera notch or curved screen to crack. I was coming from an S8+ and using the wife's iPhone 11 max in the interim. Xperia 1 is my favorite. Ordered the screen protector and case from mobilefun. Took almost a month for them to arrive from the UK. If you purchase the phone from pdaplaza use the discount code WELCOME for $10 off.
Hi all!
I plan to order Xperia 1 64GB 802SO from Japan.
According to specification, this is single Sim version.
I know, is it double Sim version of Xperia 1.
it possible to update single Sim version to double Sim? Or this problem is hardware problem?
Thanks!
I just imported a 1 ii and 1 for 240 and 190 USD. The 1 ii is new and 1 has some paint off the fingerprint sensor and other than that new condition, not even micro scratches. Japanese dudes take care of their stuff for sure. Good deals I think. I have a few Japanese Sony already two units xz3 801so, one xz2p from au. Annoying things about these are missing frequency bands. Here I don't get LTE plus. I know you can unlock bands but man it's so complicated and have to bootloader unlock and root. Can someone tell me how they lock band in the first place that's not even fixed by flashing different country firmware with flashtool. I don't recommend flashing these Japanese phones, you will lose NFC, as far as I know no cure due to different hardware and drivers, nobody put in the effort on this. The 1 and 1 ii it's not bad at least they let you put in apn ok. The xz3 you have to use another program to force apn. Someone needs to make a thing that is like the qunlocktool to flash these phones to have all radio frequency. I live with 4g no 4g+ since got these phone so cheap. One for me one for wife. Minor issues used to bug me a lot and read a lot about it and in the end gave up, keeping the phone stock is best.
Oh I came here to complain the camera on these Xperia 1 and 1 ii, vs xz2 premium. Where did the iso 51200 go? Max is 3200. Seriously. The iso 51200 on the xz2p is really good and fun to use. I have a canon 1dx and 1dsII. So now the camera is like going backwards. The 1dx can do 51200, 1ds only 3200. I mainly use the 51200 to capture my 2 year old funny sleep postures and room is dark. 51200 is the way to go. I am guessing the 1 and 1 ii is not capable due to the lack of black and white lens. The xz2p I had the problem with coating scratching off on the lens glass and I didn't know so I kept scratching it off. Now I got some cerium oxide and will polish it. Current photo has a red glow when taking on high contrast areas lol. Once I fix the glass I may sell it, debating if I should keep it just for the camera and the 16:9, so rare now, and the phone itself is pretty rare. There are not a lot of discussions on these au and Docomo model Xperia. Should since you can get these dirt cheap and brand new from Japanese contacts if you know people. Unlock is 24 bucks with S1 network unlock or qunlocktool.
If anyone have a way to unlock the bands without going through the Qualcomm Snapdragon band unlock guide let me know. I have one xz3 bootloader unlocked and it shows annoying warning message when phone start. Apparently no way to relock it before I sell it. I think I'll keep this unlocked bootloader xz3 to play around and learn stuff. I have 2 each from xzp to 1 lol. I hoard Sony flagships. Now eBay has seller promotion 10 items I will sell some phones. Keeping just the 1s and xz2p.
Well most of you just like me got the Softbank/Japan variant of this phone,I'd like for you guys to dig into smth even better I'll try it too, I owned Japanese Xperias before and there was a way to convert those to official global variant using certain files in flash tools while avoiding for instance lets say the baseband related stuff and they worked like a charm though this time around given some are 128 some 64 I am not sure will it work, but for starters we will need unlocked bootloader to at least backup important files before approaching this, I heard people achieved bootloader unlock : yes via lets say s1 tool any insights?
to me it seems the single sim J8110 or J8170 might be closest
