Hello Everybody! First Post, Just Joined.
i am using leeco le s3 x522 in 2020 (funny na?)
my 4g was not working and bands were not showing in Pakistan so i decided to try to fix this thing.
i updated to S2_X522-NA-OP-IFXNAOP5802102141S-5.8.021S using TWRP but still no luck.
then i tried [s2_india_sparse_images for x526 indian version] using qfil but the problem remains the same.
accidentally i messed up with QCN backup restore in qfil and ended up with NO SIGNAL/Radio OFF.
now i have tried each and every method, tried all roms for x522,x526,x520,x527, also tried by editing x526 qcn files (found online), x522 qcn and xqcn files and writing my IMEI number, still same.
i have been studying XDA for more than a week, no thread, no post, no link left to read and try.
now the situation is, when i erase my modemst1&2, Radio is ON in *#*#4636#*#* menu, and several bands are being shown but with NO IMEI.
when i restore/write my IMEI with any tool or with qcn/xqcn file, Radio turns off and bands vanished.
Sim cards are detected but with NO SERVICE, its been a week trying all the methods, tools, files, roms still no luck.
if any of u guyz have any idea about this problem or HAVE ANY QCN/XQCN FILE FOR LE S3 X522 (mentioning rom and modem version from which the qcn/xqcn file is backed up) PLEASE SHARE FILES OR SOLUTION.
(NOTE: i have tried each and every post of Le2 and Le S3 so referring to any post is not helpful)
SOLVED [LeEco Le S3 X522] No Service, Radio Off]
ALHAMDOLILLAH!
So after 1 week of hard work and in next few hours after posting my problem here, i got required QCN file from a Russian Forum, edited it, changed imei, restored from Qfil in HS-USB Diagnostic Mode 9025 and BOOOOOM, got not only my signals back but 4G also.
here is the link, since i cant share link before 10 posts, so please copy all three lines below altogether to get file...

Hey guys, im writing because i tried almost everything and nothing helped me to revive my gsm signal... i can get only 3G/4G in the city but i cant connect to 2G. It started i flashed MM dump using adb https://mega.nz/#!jMphmZjK!sfoFLx1Jm5NXvdcpJD9Ua1nVfj-J9KWc3K16JvNDFS8
i think its in modemst1.bin and modemst2.bin since i they are not in any other firmware file. My IMEI changed a bit and when i use CDMA workshop it says GSM OxDEAD. I have read also that im not the only one having this issues. I tried to change my IMEI using QCN backup, NV editor. I did NV Rebuild using service menu. I tried also to restore my EFS which i backed up sooner but it didnt help me ( for info i backed it up in cwm and i have efsxxxx.img 14MB and efs.ext4.tar 136kB files). I tried flashing Cyanogenmod, DevBase, Stock lollipop. Nothing helped. Could anyone help me or have any advice? Im desperate. Thanks
I solved it somehow. I dont understand it at all but i downloaded this files https://www.dropbox.com/s/6w6gwrcuv5unlxq/G900f.rar?dl=0 recovered qcn through qpst and its working after restart I hope somebody will find this helpful (those who flashed modemst1.bin and modemst2.bin from MM dump)
How to flash te file you posted?
Hey guys, I flashed a JUI ROM, and it flashed something to my EFS partition that is forcing my device to reflect the CoolPad S1 LTE bands (which unfortunately doesn't support any USA LTE for my carrier.). Immediately restoring my backup didn't work because it failed to decrypt my Internal Storage (meaning I had to wipe device.)
I've been unable to get the LTE bands back. Does anyone know what I can try? I've tried the below items.
* Tried manually enabling bands via QPST or Qualcomm Tools. The bands show up in certain apps, but device does not connect to them.
* Completely wiping and restoring device via QFIL restore by Tora33. Still seeing no LTE.
* Flashing USA 21s latest stock ROM w/ 5.8.19s modem. No go here.
* Reflash do manually all of the 5.9.23s firmware (w/ USA modem), no go.
I do not have an old EFS backup which I think is what I am in need of. But I think it's device specific...if anyone has any ideas, please let me know. I am missing this device since I need LTE for coverage.

Yes, there is a TWRP recovery here on XDA that is a full unencrypted backup of 5.8.19s you could flash it to restore your bands.
I do not have the link at the moment. But I will post later today or you could search for it, it may be easy to find with a simple search for TWRP 5.8.19s recovery.

Thank you, I've made threads about this issue and tried most of the methods Ascertion tried to fix his LTE with no luck. Looking forward to trying this!

Hey, unfortunately I found the link and it did not work after restoring this. I do not know what JUI did, but it really did not play well with USA Le Pro3.
I just tried this and no go either.
https://forum.xda-developers.com/le...lock-bands-leeco-le-max-2-fix-t3439154/page25
I think we are SOL, unless a dev can chime in that understands how the modem is programmed.
EDIT: After trying this guide https://forum.xda-developers.com/le...lock-bands-leeco-le-max-2-fix-t3439154/page25, I was able to get LTE back after flashing AICP after enabling the bands in the link. I am so happy! I'm going to see if reflashing EUI restores bands. If not, I'll just stay on AOSP ROMs lol.
EDIT2: EUI has LTE again.
Glad to hear things worked out, I had a very similar problem a while ago but I believe I ended up having to unbrick my phone(using some completely Chinese Le Eco recovery tool). Then by going back to EUI 18s and 19s I had the ability to connect to LTE. However, the problems I started having was LTE dropping in and out, and on EUI getting a random SIM NOT INSERTED error requiring a reboot/restart. It actually doesn't drop or slow down on Lineage while using data, only when my phone isn't actively using data, i.e. android auto/sitting on homescreen . Anyway, I'm just hoping you can give me the link to the flashable 19s so I can quickly try that, also let me know if you experience this intermittent LTE drop thing, thanks!

I've searched and done so many hotfixes but
Nothing work and I think it's time to ask the experts.
Here's the Problem:
My Phone was in a HardBrick, then Gladly I've made it back
by reflashing the Stock Rom of Cool 1 (EUI 5.8.18s) using QFIL
And then I noticed that there is no network signal even though the sim card is being detected. I've searched on Google on how to fix it and I find out that it must be the IMEI and I re-write the Original IMEI from the Box on my Device successfully but still, nothing happened, I still have no Network Signal. I've done reflashing again through TWRP But still, nothing happened, I tried to switch to (EUI 5.8.17s / 5.9.26s / JUI and MIUI 9) roms. I also tried the *#*#4636#*#* and change the unknown to WCDM / LTE and everything is still the same No Network Signal.
Now I am wondering if it is because I inputted an International IMEI which is written in the Box of this phone, or might be because of my baseband or kernel.
By the way, I'm from the Philippines I'm using (Globe/Smart) Teleco's Sim.
If there's anyone who could show me the right thing to fix my device, your help will be appreciated.
If You are also suffering a HardBrick Case with the same device I am willing to help you to the best of I can do.

Hi there!
I had the same problem, tried rebuilding IMEI's even from my other phones etc. After rebuilding IMEI, appliying qcn with QFIL (after changing to diagnostic mode)... IMEI was available, but network won't work.
But I repeated with .qcn found for C103 on internet .... and it works like a charm! Connects to network!
drive.google.com/file/d/1jp41j9n68qfIVwAKl2Uu6rU6tsfrbJhx/view?usp=sharing
My phone:
- LeRee
- OS: LOS 15.1
Just try that, you have nothing to loose. First step - let's network work
It workedd!!???
Thanks for the .qcn file link it workedddd like charm! I was searching for 2-3 days and was getting really mad ! Thanks for sharing file ! My network showed after qcn file flash!

Hey, r u getting 3g or 4g siginal?... After flashing this, I'm getting only 3g...
Hi, I am having same problem but none of the above method worked. Pls anybody help??
Basically, my phone is X829, but it came with X820 Software on it, and does not get service in the USA.
I've tried flashing custom roms and X829 roms and sometimes get service in certain areas, but not everywhere.
I have seen my friends using x829 in my area and it works for them.
First, I cannot find a rom that is for USA and x829. it's either missing files or cannot be flashed with TWRP, I have to do it manually.
Maybe I am not wiping data correctly? Do I have to wipe internal storage as well? But then my file that I'm flashing gets deleted.
In the end, it could be some hardware problem as to why my phone radio is not picking up the signal.
But I need the proper USA firmware and Rom to make sure it's not a software problem , so if I can get links to the files and a step by step tutorial on flashing them, that would be great.
I have succesfully backuped my QCN via qpst/qfil. When i restore via qpst/qfil it also states succefull but it doesnt seem to be since any edits made to the qcn file do not seem to stick. Any advice where I might be going wrong?
Details. I have kb2007 and converted to EU version Kb2003. This worked great with A11 but with A12 dual sim function dissapeared. In A1 sim2 IMEI is null. I backed up my QCN in A11 and then upgraded to A12 and then restored qcn. But my IMEI still shows Null for sim2.
lol its not gonna work don't waste your time
Did you mess with the encryption in any way? On either of the ROM's at any time? Was the device encrypted/decrypted before flashing OS12?
I'm not sure what is needed to restore dual-SIM to the KB2007 but you might want to also look at the KB2001 Beta 1 for Android 13. Dual-SIM works in that in a KB2007 as well. I tried copying some files from a KB2005 to a KB2007 to see if that would work though QPST back when Android 12 first launched but I could't get the second SIM slot to stay enabled. The one time it did, what using a partial update but when the device rebooted, it turned to null. I think the IMEI needs to be written to the second SIM for it to actually remain working. I have no idea how to do that though to even attempt it.
