Title says all. First of all, I apologise if this mistake seems too easy to avoid.
I used some site as a guide on upgrading my E6553 to 7.1.1. What I don’t realise is the firmware that they labelled as E6553 was actually meant for E6533. My stupid ass went ahead and flashed it, and now my phone is stuck on a “sim card inserted, rebooting” loop even though there’s none inserted. I tried reflashing the correct ftf but flashtool flagged my phone as E6533 permanently.
I tried Xperia Companion software restore too but failed. Can anyone help me change from E6533 back to E6553? I really need my phone

Hello World,
As I'm a stupid boy, I've used flashtool to downgrade a Xperia Z to a rootable firmware Xperia Z_10.3.1.A.2.67_SFR 4.2.2.ftf
I've then used rootkitXperia_20140719 and XZ-lockeddualrecovery2.8.3-RELEASE.installer
Reboot, every thing seems ok except that my SIM card is no more detected. "Please insert a SIM card and restart your phone".
The SIM card works well in another phone. But I've never used it in the Xperia Z. IMEI is still correct in Xperia.
Why am I stupid ? Because I don't have any backup. So, what could I do now ? I've try touse flashtool to flash other stock roms or baseband without success. :crying:
Really stupid. I found what I've done wrong: I've used Flastool fastboot mode on locked bootloader...
Any idea to solve ?
Me too
Did you find a solution?????

No
Yes, I found a solution: The SIM card was not well inserted. Change the side when inserted (electronic part should back oriented) and everithing works well.
i have Z3 compact (D5803).
i have used it for a long time.
After installing "D5803_2157_Concept_6.ftf" via flashtool, my z3c lost network.
i have tried tons of methods:
i have flashed "D5803_4.4.4_23.0.A.2.93_TR.ftf", and rooted.
i have flashed "D5803_23.4.A.1.264_1289-4791_R2C.ftf" and rooted.
i have repaired the firmware via Sony PC Companion 2.1
i have repaired the firmware via Xperia Companion
i have tried installing twrp, when i try to install any custom rom, i get an error like this: "this rom is for d5803, d5833 etc etc... but you phone is differen"
i have tried this: http://firmwaremobiletools.blogspot.com.tr/2015/11/how-to-remove-pattern-lock-from-all.html
i have tried this: http://forum.xda-developers.com/z3-compact/general/guide-unlock-z3c-international-bands-t3091344
So i can flash any ftf without any problem.
But i can not install anything via twrp. (although i can install twrp)
i can root roms without any problem.
But phone can not connect to network..
it always says "invalid card. emergeny calls only"
- there is no IMEI problem..
Anyne have any solution for my problem?
Thanks...
- i have attached screenshots of *#*#service#*#* and *#*#info#*#*
Any help?

Have you tried cleaning the sim card?
Do you have a different sim card from another phone you can try?
There is also a hardware reset button next to the sim, have you tried that?
I looks like there is some sort of corruption in a system volume, looking at the error states listed.
What was the results from using PC companion to fix? any error messages?
Did you restore your TA partition? That would have been damaged in the flash to 6 concept.
Have you tried finding the right firmware for your country/provider via Xperiafirm, download it, make a tft from the file, then you know you have the correct baseband flashed.
Don't know what else to try, sorry.
Hello, thanks for the answer..
My z3c lost network, after installing "D5803_2157_Concept_6.ftf" via flashtool
I have tried cleaning the sim card.
I have tried different sim cards.
I have tried hardware reset button next to the sim.
After PC Companion, there was no error message.
I have tried all different ftf files for my country. (4.4 - 5.1 - 6.0 etc..)
No solution
it always says "invalid card. emergeny calls only"
Put a stock rom back on and send it back to Sony for repair
Dear Mods,
I am aware that I am posting in wrong section but I haven't got any help in the Q&A section since Aug-2016

Hi Experts,
I have searched the forum and after flashing for three sleepless nights, I am still struck with the unknown baseband issue.
The details are:
C6903
BL Unlocked & now its locked using Flashtool (DRM or TA backup is unavailable )
Currently the phone is struck in boot loop in .534
Used Flashtool ver. 0.9.22.3 & 0.9.18.6
Latest EMMA & Xperia Companion
My phone hanged when listening to the music and when I force restarted the unknown baseband showed up. While flashing I got the baseband back after flashing .518 however it hanged again after two days and I lost the BB
Now I am struck in boot loops on .534 and .518 both. I can boot into .290 successfully. Can someone please guide me to the correct method of restoring my IMEI permanently.
P.S. As per my short experience with C6903, I believe something stops the boot of .534 and .518 after first boot. Means I was not able to boot into .534 but accidentally when I flashed .518, my phone booted successfully. However now I am unable to boot into .518. May be I am missing the piece of puzzle that an expert can provide.
I would really appreciate if someone can help. Thanks in advance~

Anyone...
1st you shouldn't write it here. Mods will remove it and it's more worthless work for them.
2nd have you considered that your phone might have some hw issue? You're talking about some old sw versions, so just flash .236 via emma and if you still have the issue, I would consider the device defective. And then it's better to buy a newer phone, z1 is now pretty old (considering that it's a flagship of 2013)

No. There is no firmware for Latín américa o for Spanish People in general. But I thing something really Bad is happening, no matter wich firmware o use.
https://www.sonymobile.com/ar/products/phones/xperia-xz2/
Look into Xperifirm
If the problem persists after a clean installation and as fullwipe, let your phone get repaired.
How did you aquire this phone and was it a brand new or used one?
I think its blocked by a tool there admins of a company can select that people can install and also disable features on the phone.

Sometime ago, I used Xperia Flashtool to flash a DE variant of Kitkat for our Xperia Z, but after that flash my phone don't recognize anymore the Sim Card!
It's possible that I've wiped something important? I tried Xperia Companionto restore the stock firmware but the SIM doesn't work anymore.
Have you any ideas of what may gone wrong?
Also the battery may be done, because when it reaches 0% level, when booted up requires to "optimize" apps and that takes about 5minutes/10minutes
Thankx you
It SIM-Locked, you'll need to unlock it over at your carrier. Flashing doesn't lock SIM, it just means it had a tripped firmware.

Previously it had the Central Europe firmware, or maybe Italy's one if it had that. I used my Sim on it before the flashing :/ Now if I put the SIM into it, it reboots because it detects, but when rebooted, no sign of life
Try flashing original firmware ?

I just restore the firmware with Xperia Companion (10.7.A.228.R1E) but I plug into the Sim, it reboots and then it says no SIM inserted, it only reboots if you plug or unplug it
Wifi and NFC works good.

Oh I discovered, it is no the firmware, it's due to Sony's crappy sim tray little piece of plastic, that needs to be changed
I return on this topic because it's still not resolved.
Maybe it's the SIM card slot broken or pins. But the strange thing is that the phone correctly see that I put an actual SIMcard inside it. It reboots and then says just "No Card Inserted".
I've a c6603 Customized IT device, that was for years stuck on A4.4.4 because it didn't received Lollipop via OTA.
Anyway the phone works for everything except for vibrations and SIM support so calls,data etc...
I'am sad for this, I wanted to try A12 for this, it came out with even May 22 security patches!
