The procedure is as follow:
Boot in fastboot
fastboot recovery
boot in recovery
If not on internal drive TWRP has MTP, first copy rom to internal drive
install rom
reboot and wait.
You can also copy rom to external SD card and select and install
etc
Succes
I found out that Wifi and LTE were linked together.
What I did is next:
It's a bit risky, but don't panic. Just follow the sequence
Copy "xiaomi.eu_multi_HM4X_V8.2.18.0.MAMCNEA_v8-6.0" on a external SD card and put in your phone without any sim card
Delete eveything, also system and cust. etc...
First update your TWRP to 3.1.1.0.
If you have wiped the system, then you will have to fastboot the TWRP again, reboot in recovery from the same fastboot session.
Now install the rom from external SD card if you don't have the rom on the internal memory anymore.
as long as you are able to boot...
I did, but no improvements for me.
I tried several roms.
Right now the miui9 from here is the best and stable.
Most important for me was the VoLTE, which was freezing my phone and is working good now.
Have you deleted System too?
Are you sure you have enough battery?
have the phone on charger for a few hours
Copy the rom on external SD card
Once in fastboot, just fastboot twrp and reboot in twrp and install from sd card.
It's getting better and better.
Updated via OTA
VoLTE works better, not disturbed by WiFi.
Still no manual search of network, but does not freeze anymore.
Keep the good work.
Update from HM4X_V8.2.18.0.MAMCNEA_v8-6.0 to M9 works great too.
No manual search, but auto search works too.
No freezes anymore.
Seemed to be a VoLTE problem.
Which rom do you have installed.
Try HM4X_V8.2.18.0.MAMCNEA_v8-6.0 and see if the freeze remains.
If it's the same I had, then it has to do with VoLTE.
From this version you can update to the newest M9.
If not, please provide more info about rom and phone.
Works great so far on my Redmi 4X, after an update from 8.2.18.0. where the previous updates gve problems with VoLTE.
No freezes anymore.
Manual network search on Sim 1 is still not possible, but automatically connection works and no freeze at manual search.
With my original rom with bootloader I was able to choose the language and region.
Is it possible to add this feature somehow in Nougat for Redmi 4X.
Who has the golden tip for me!
Okay, with a search this problem seems to be wider.
After a few trials I found out the next.
Put your sim with Data in Sim 2 slot.
Assign the data to sim 2.
Call's to <ask> or sim 2
Now you will be able to have stable connection and no network problems.
Still can't search network manually on...
Make sure you have enough battery.
It will be difficult if no system is in the phone.
I would suggets, just leave the phone charged for a few hours (24 maybe)
The LED won't lit, just try to charge.
If no succes, try to take out the battery and charge alternative way.
Am I really the only on who has this problem?
The search fail occurs only with Sim 1.
Seems that when it tries to search for LTE, the phone crashes and goes off.
Sim 2 completes the search, but does not give 3G or 4G in the list.
Hi,
I am new, just got my Redmi 4x Global and unlocked.
First I tried the original rom, which worked fine.
I could switch with sim cards.
With 6.xx stable no problems.
With 7.xx I am having problems with sim cards.
If I try to search gsm network manually, the phone goes off.
This also happens...
