I tried it now and i got error "Skiping MD5 check: no MD5 file found"

XUmi

It doesn't say anywhere what kind of recovery i should use so i just used TWRP and i got that error, maybe thats the problem no? It has to be done with another method?
On the thread it says: "Do not UNZIP it, put ZIP on phone, flash it via the recovery or use Rootjoy Tool"
I haven't tried with Rootjoy but i don't think it will work right?

Hi, i've tried this "eMAX Mini 6FA6-ZP1-P5002 11/17/2015 update" as well right now and i still don't have LTE. The only thing i haven't tried because i don't know how, is the Stock from NeedRoom you sugested.

Thanks for the help. Any other thing i can try? Maybe is something wrong with the hardware itself...

That was not an error message that made stuck the flashing process. However that doesn't make sense to try out that version since that's the same one as that's contained in the earlier flashtool version. Probably your bearer refuse to connect this phone to the 4G network. That might be IMEI related but you should ask them, your service provider about this issue. Maybe they know the reason. At least, they can tell you whether your phone is allowed to connect their 4G network or not.

The error "Skiping MD5 check: no MD5 file found" made something to the flashing process because i didn't get the version "UMI eMAX mini_001_9/25/2015" like i should...Thats the reason i asked "It doesn't say anywhere what kind of recovery i should use so i just used TWRP and i got that error, maybe thats the problem no? It has to be done with another method?"

I already contacted my SP and and i'm wainting por an answer from them bue i don't think its something with the IMEI and the provider, since the last "update" (eMAX Mini 6FA6-ZP1-P5002 11/17/2015 update) i lost even the 3G...:/

The MD5 file contains a checksum to verify the size of the backup file. However, the TWRP restoration process can just skip that verification, that's not an obligatory to be processed. So, that was not an error, just a notification.
This recent update has no effect on the 3G connectivity. I also installed it on a phone.
If your phone is defective, then that's definitely not a common issue. I'm afraid, I can't help you anymore remotely, without holding your phone in hand. You should contact your reseller.

Hi there,

and thanks in advance for your great and helpful work here, bencebacsi.

I got my new eMax Mini yesterday, unfortunately I have the same issue like OP: no 3G, only 2G - LTE not testable (not provided).

Weird thing is: I had 3G (H+) for a few minutes after first switch on, then I switched on WiFi and after switching it off no 3G anymore (just E or G).

Firmware-Version: 5.0.2-01001
Software-Version: UMI eMax mini_001_10/23/2015

Is there any chance to fix it by an update or do I have to send it back?

I like that device!

Hello Sachimi,

Just to make it clear, do you use the SIM1 slot anyway?

Saschimi

Yes, I do.

And I have 3G with my SIMcard in my other phone. This evening I will try it with the SIMcard of my girlfriend who uses another provider. If it wont work, I have to send it back.
