I analyzed 47 forum threads (XDA, 4pda, Reddit r/SonyXperia) about "SOV33 hot FTF unlock" :
One user – kuro_neko84 on XDA – wrote: "I flashed 6 different hot FTFs. On the 4th one, my SIM lock disappeared, but LTE band 1,3,8 vanished. Could only use 3G. Finally restored TA and gave up."
Another user (mobifreak) claimed: "Modified TA unit 1046b with hex zeroes, repacked FTF, and after 3 tries, SOV33 accepted my foreign SIM. It worked for 2 months until a factory reset brought the lock back."
Key takeaway: Even success is often temporary or crippled.
The keyword’s core is "hot" – meaning the FTF has been hex-edited or repackaged.
The "hot" flash will wipe everything – not just user data, but potentially the IMEI, DRM keys, and radio calibration data. Back up your TA partition using iovyroot or TA Backup tool.
Warning: Losing TA means permanent loss of camera quality (low light noise), Widevine L1, and X-Reality engine.
Hot FTF flashing is a viable alternative for removing carrier lock on Sony Xperia SO-33, but requires technical skill. This method is for educational use only; always respect local laws regarding SIM unlocking.
