[Q] GT-P7320 stuck on 2G mode after flashing to ICS - General Questions and Answers

Posting my query here as instructed since I'm a newbie account and cannot reply to a Dev thread.
Following the thread here: [ROM][4.0.4][P7320/T][CWM] Arlic's ICHI ROM 1.2, compatybile with P7320T!
I have a Galaxy Tab 8.9 LTE from Hong Kong on the ChinaMobile network. (GT-P7320)
- I made sure to backup my original stock setup in CWM before doing anything.
- Then flashed the Arlicc's ICS rom sequentially as instructed (1.0 > 1.1 > 1.2)
- Everything seemed to install fine with no errors.
- However after the intitial wipe to factory conditions, load and new device configuration, I noticed that although I had signal, the data connection never went above "E"
- I checked my APN settings and made sure 4G/LTE was enabled (APN settings)
- No matter what I tried, couldn't get my LTE connection back, couldn't even get 3G back.
- Baseband reads as P7320ZHLC1
Since it wasn't working, I go to restore my original rom in CWM > Restore
- After restoring and then resetting everything back to factory conditions, I find I get no signal at all!
- Go to configure mobile settings, it says SIM card not detected?! (Haven't moved or dropped the unit, or touched the sim slot)
- Baseband now reports "Unavailable"
- The whole device also reboots approx every 30 seconds.
I think my backup is borked. =/
- I flash back Arlicc's rom and at least everything runs correctly. Apart from the lack of data signal.
From memory, I think my baseband should be P7320ZHLC2 for Chinamobile, but I can't be sure.
Unfortunately, none of the Hong Kong stock P7320 firmwares are on sammobile.
Help?!

Hmm... don'tcha just hate it when this happens?
..at some point between me putting the Tab down for dinner and then coming back to it again the 4G suddenly started working.
There are only two things I can think of that I did differently this time.
- I only wiped the caches / factory reset before updating the firmware, I didn't do it afterwards this time. Booted straight in after flashing the ICS rom.
- I connected to the home wifi to see if it would grab any extra settings out of the ether... non of the software updates reported anything downloaded when I put it down for dinner.
...yet when I came back and rebooted again. The 4G icon came up almost immediately?
Strange.

Phone stays in Roaming mode.

I've Installed this yesterday, but I'm experiencing a couple of bugs.
I first did a format (disk + dalvic),
then flashed Codename Android v3.3.2
then Camera + Backlit Fix
and then Codename Android GAPPS
Because I have a S-on device, I flashbooted the boot.img from the CA Gapps zip. (other zips didn't have that file)
Everything works very smoothly, but the errors/bugs I encounter are:
4. When I insert my SIM-card, I'm always Roaming, untill I enable WIFI, then I can make phonecalls.
So when WIFI signal is lost, I'm at Roaming and mobile-internet doesn't work.
Does other people have these issues, or is it because of a wrong Boot.img I flashed?
Click to expand...
Click to collapse
Since I don't want to post this in the dev section anymore, I'll continue here.
This problem first started with Codename Android.
When I install an other ROM; for example Blindbean, the problem stays.
Then I tried MIUI from Shrome, same problem.
(always with format disk and clean dalvik cache)
This night I installed the ICE-DS v4.4 ROM, and everything works fine again.
But when I install Blindbean again, problem is back.
You guys have any idea how this is possible.
Boot.img isn't suppose to be in gapps. Should be inside the rom itself.
When flashing a new rom always do a full wipe.
Sent from my HTC Desire S
Ok, so I did again couple of hours of googling and stuff, and found some interesting stuff.
In our country, we have 3 mobile networks with their own towers. (proximus, mobistar, base)
But 2 of them rent these towers to other carriers. (mobistar for example to Telenet)
It appears Jellybean (I have it on every JB rom) sees a difference between the carrier and the tower-network. (If you get my point)
So I have to enable Roaming to be able to use my carriers network.
So far I can see, no additional costs.
But this still is a strange bug, that started with JB.

[Q] D2G wifi issues

Hello peoples, hoping for a little help here.
TLDR; After downgrading firmware (big mistake) from 629, i reflashed back to 629 only to discover that my wifi will either connect and work intermittently, or (as is the case ATM) my wifi will connect and immediately disconnect, everytime it connects. I would like some guidance on how to get wifi working consistently, regardless of what firmware i need to be on, or what rom I need to flash. If i can get a rom that has wifi and camera that would be a plus. I searched and found one or two threads on the issue but related to earlier OTA upgrades.
More details;
Accidentally phsically destroyed my SG S3 a week ago or so, which meant I had to go back to using my wifes Motorola Droid 2 Global
Decided that since I was stuck on Gingerbread, and that since Verizon doesnt care about D2G anymore, I was going to root and upgrade, so I started researching and experimenting. That was my first mistake
So I;
- Tried to downgrade to 2.4.330 firmware per the (wiki.cyanogenmod.org/w/Install_CM_for_droid2we) Cyanogenmod wiki instructions for droid 2 global, which "soft bricked" my device (stuck in bootloader with a "service req'd" message). From doing a bunch of searching online and reading, I'm guessing its because the phone was previously on the latest version of android pushed to the droid 2 global, namely, 4.5.629.
- I then found (rootzwiki.com/topic/23207-how-to-sbf-unbricking-root-d2g-629/"official 629 sbf) and reflashed my device with that (the link at the top of the thread)
- I dont remember everything I did next (or if i even tested wifi at that point), but i know the device booted and "looked normal". I know I then rooted with framaroot, and installed bootstrap mod (1.0.0.5), and did a bootstrap recovery (im guessing this is synonymous with installing clockwork mod??)
- Found and flashed (installed?) CM9-D2-01032013.zip (cant post links, sorry new user restriction) -- rootzwiki.com/topic/28082-d2d2gdx-cm9-build-thread/page-90
- The rom installed fine, but when I booted up, and tried to use wifi, the wifi would connect, but the internet wouldnt work (no response from any website).
- I downloaded some kind of "wizard" bootloader, that had a wifi fix (sorry I cant find the link). I rebooted into the bootloader, ran the wi-fi fix, and then rebooted. No luck (no change).
- I figured it was an issue with the ROM, so I flashed liquid_droid2we-ics-v1.62.zip
- Unfortunately, the same issue persisted.
- I then reflashed BACK to 4.5.629, using the --(cant post links apparently since im a new user) (rootzwiki.com/topic/23207-how-to-sbf-unbricking-root-d2g-629) -- "official 629 sbf"
- Wifi STILL does not work. At first it connected, and was responding, and then it stopped responding.
- Wiped cache partition
- Wiped data/factory reset
- wifi now connects, then disconnects immediately.
I'm at a loss here. I am on 4.5.629 using the official ROM, I tried a factory reset after a cache clear. I even found some suggestions about turning battery saver mode off, which I did. WTH am I doing wrong?
EDIT 9/19: Just discovered that I can connect to insecure networks just fine. I've read about changing my router settings as a possible fix, but I cant do that for any router thats not my own. In addition the wifi was working on my router before, with the same settings, so the phone broke somewhere along the way.
I was able to resolve the wifi issues I was having by simply unplugging my modem and router (though just rebooting the router would have probably fixed it). I don't know exactly what caused the issues, but it was probably multiple factors, including having a droid2 and droid2global right next to each other trying wifi, flashing multiple roms, and having dd-wrt firmware on my router (or all of the above). In anycase, doing a reboot of the router, caused wifi to work again consistently on both my droids.

Verizon HTC One M8 Won't Connect to 4G/LTE

I was running the official CM12.1 on my Verzone HTC One M8 and everything was working as expected. About a month after installing it, one day my phone stopped picking up a cell signal altogether. I re-flashed the CM12.1 that was on my phone and have only been able to pick up 3g signal since then. In the cellular network options i have tried to change the settings but the only settings are global, LTE Mode and LTE/Legacy 3gpp mode. The latter 2 don't work and the first one works but only picks up 3g. I'm not sure why the LTE/CDMA option isn't there.
In an attempt to fix it, I have restored with most recent version of TWRP back to a couple previous backups from before this issue presented itself but it still only picks up 3g.
I updated the firmware/radios using the thread below and it didn't change anything.
http://forum.xda-developers.com/ver...-4-17-605-9-stock-resources-firmware-t3196906
I flashed the stock rooted firmware in the thread below:
http://forum.xda-developers.com/ver...-4-17-605-9-stock-resources-firmware-t3196906
I'm currently running the fluentrom from the thread below but still nothing has changed. It will only pick up 3g.
http://forum.xda-developers.com/ver...rom-fluent-rom-v1-0-rls1-4-16-1540-8-t3007173
I also go a new sim card but that didn't change anything either.
FYI, it's s-off
Any suggestions to get LTE back?
Flash stock recovery and run a factory reset from within recovery. This will reset the NV partition to factory settings and "should" clear up your data issues.
The NV partition is a lower level partition that can become corrupt from flashing ROMs. One would think by flashing radios the issue would be fixed but on HTC devices it's not. The only cure is a factory reset from within stock recovery.

Phone has no radio/baseband, help please

Somehow I ****ed up and now my phone cannot receive cellular signal at all. In about phone, IEMI number is unknown and in SIM card info, everything is unknown. What I did was this.
1. Flash CSC Selector on my existing ROM selecting ATT CSC. Everything was fine (aside from no voice/wi-fi calling)
2. Wanted to update to latest stock PDA/radio/bootloader so I did (through Odin.) Everything still good.
THIS IS WHERE **** HIT THE FAN
3. Flashed TWRP.
4. Formated data, flashed CSC selector selecting ATT, flashed Makisk, flash Makisk-PHH rot.
After that, no cellular signal at all.
Can someone help please? I really need this phone for work and if I can't get it working tonight, I'm going to have to go to AT&T store and ask for the cheapest phone they got until I can get this fixed...
BTW I already tried re-flashing everything to stock through Odin and it did not help.

Follow the instructions. Faced the same problem took hours to figure the **** out.

[CM14] Cell Signal can't connect, turns off immediatly after trying to reconnect

This is consistent across every CM14 ROM I've flashed. I am upgrading from CM13.
The signal bar at the top is blank as in "no service", it attempts to reconnect and show a signal for a split second but then goes back to "no service" again. When I remove my SIM card and reboot the problem simply vanishes, but of course I can't get LTE
Firmware: PCA
Recovery: TWRP 3.0.1.0
I have tried running the ROM stock with no data restore and I have tried flashing APN settings from this post.
I at first thought it was a CM14 bug but then I read that others had no problems with CM14 ROMs.
Assuming you actually have a SM-G900P (since a lot of people ignore that little detail) it's probably a matter of Cm14/14.1 doesn't appear to be wholly happy with anything other than the latest baseband, which is now PK1. To get it, just reflash to stock with Odin and then poke at the thing until it gets the two OTA updates that will bring you up to PK1. At that point if you like you can poke at the controls to update the PRL and Profile (just to be sure everything's good) and then let me suggest you make a call or two and/or send some SMSes to be sure you didn't mess something up when you tried to change the APN settings one almost never needs to touch, and then flash TWRP (or whatever recovery you use) right back in and sideload the Cm14.1 nightly and open-gapps for 7.1. Also, you will need to do a factory reset after upgrading to 14.1 or you'll get a wholly different set of misbehaviours out of the phone (trust me... I deliberately cut corners through multiple rounds of reflashing to find out what symptoms to look for). One of the more endearing failures can be no soft keyboard, nobody wants that.
I had a bunch of weirdness happening (including completely non-functional GPS) with CM14 a few days ago, and since the changelog doesn't seem to show anything addressing the screwy problems I had, it hints very strongly that people will need to update to PK1 before they can expect the device be reliable.
OH... and don't try and enable Adoptive Storage if it asks. The performance is abysmal for some reason (around 2Mb/s on a Class-10 card that otherwise hums along at 14Mb/s) and it will make any apps that are trying to use storage run like crap.
So people have it working on PK1? Has anyone had it working on PCA?
Edit: Odin restored PK1, it didnt want to boot after the reflash. I installed TWRP and restored a PCA Backup, updated PRL and profile. I flashed a cm14.1 ROM and still had the same issues.
It also didn't wipe my internal storage when I ran odin, which I remember it doing in the past.
Worked great on my S5 900P
Gracefully I got it to work on Resurrection Remix. Idk if it was the APNs or just more stable ROMs.
I booted RR stock w/o gapps, I went to enter in the APN settings using this site and it just magically worked after I entered in only the first line. It's hard to tell if it was because the ROM found out how to connect or if the first line of the APN settings triggered something.
