[Q] Upgraded MZ600 loses 4g on ROM flash - Xoom Q&A, Help & Troubleshooting

I have looked through quite a few threads, and followed a plethora of instructions, so If I have missed something I apologize.
I originally had the MZ600 without the 4G upgrade, and decided to give that to my little brother and purchase one that had the 4G radio.
So now I have an MZ600 with the 4G radio upgrade, activated on verizon. before I tried any flashing, I had 4G. I didn't want to do the bigPart upgrade yet, so I flashed the 196 version of EOS4 for stingray (not stingray cdma) and upon boot up, i could get 3g but not 4G. It showed the baseband as CDMA only with no LTE.
I flashed back to stock Honeycomb, and after the OTA update of the radios, i had 4G again. followed the OTA's all the way to 4.1.2. still maintained 4G.
After that, i decided to do the bigPart, which after some finagling I managed to get it partitioned, and installed OmniROM 4.4 stingray (not stingray cdma)
Upon boot, I had no 4g again, and could not even get 3g data at all. so i repartitioned back to stock, and reflashed honeycomb. got 4G again.
So my question is how the heck do I get a new ROM on this thing, when every time i flash one, I lose the 4G radio baseband?

Did you ever get an answer to this? I am in the exact same boat. Same story except I performed the LTE upgrade myself. Works flawlessly on Stock 4.1.2, but I have not found a single non-stock ROM with which I can use the mobile data.
Bump!!

I had the same problem, until I called into customer service and had them totally delete my tablet off of the account. After that I had them reactivate it using the (here's the catch) IMEI, same sim.Hope this helps.

My tablet is already activated using the IMEI and has 4G data. but I am still running stock. I may attempt flashing cyanogenmod at some point to see. but for the time being I have simply dealt with the stock rom. Rooted of course lol.

Here's the Answer!!!

Long story short, the problem is that final OTA update. You HAVE to stop installing OTA updates at IMM76L. DO NOT install JZO45M. As near as I can tell, it installs some sort of radio update that is not compatible with most if not all non-stock ROMs.
If you do let that final update install, you have to take the device all the way back to stock honeycomb and start over. See the above thread for precise details.

That's my thread, and what Taylor says is spot on. All of these custom ROMs are built using proprietary files from ICS and the JB update screws everything up. It's a laborious process to get 4G working, but it's worth it.

Check the Final Update......you MUST stop at IMM76L......Activate your SIM after every patch update to be sure. If you don't have your 4G back by IMM76L you have to wipe and restart the process. The LTE Baseband files are not being flashed to the radio properly.

[Q] Service problems with the HTC Inspire

Since last night (maybe even the night before) I've been experiencing service problems with my HTC Inspire. It'll recognize I have a SIM card at times, and then It wont. I rooted my phone following this thread (specifically this video) I've had my phone rooted for briefly a week and after I finished that video, I left it at that and didn't follow the next video on how to flash a custom Rom. Any ideas on why this problem is occurring?

The downgrade rom is an older Desire HD rom that is used for the purpose of rooting. It really doesn't play nice if you leave it on the phone. You need to flash attn1's updated stock rom and radio from the developers forum if you want to stay stock rooted. Otherwise, just flash a custom rom and matching radio.

Well apparently he used bubby's simple root, which if he at least followed that through to completion, meaning the stock rooted ROM got pushed to the phone, then he shouldn't be on the downgraded ROM.
OP...
Under settings > about phone > software information > baseband, what number is specified?

Hmmm. I'm not sure what rom the one click leaves you with, but the hack kit left me with a pos Desire HD rom that obviously didn't belong on the phone. I had to go somewheres between the time I rooted and flashed my current stock rom, so I got to play with it a bit. Mms didn't work, it wouldn't allow me to setup email, and, despite connecting to wifi, it wouldn't open web pages. Mobile internet did work, but the speeds were horrid. After booting it took forever to get a signal. Idk if this was the downgrade rom used to get root or a different rom flashed afterwards, but to me it was still a downgraded rom regardless. Once I flashed attn1's stock rom, it was all fixed.

The Rom installed at the end of Bubby's method is very usable. It seems like a stock Rom. I didn't notice anything missing, but I didn't use it that long.

Lol.
That ROM was never intended to be left on the phone. It shouldn't have been some mystery needing to be solved, as from what I recall, it pretty clearly tells you that a new ROM needs to be flashed to restore the Inspire to a fully functional state.

Yes, I do recall it saying something along that line. I just didn't expect it to be that non functional. I was hoping to use it for a few days until I made a final decision on what rom to flash. Fortunately, I came across attn1's rom later that day. I do recall when researching Bubby's one click method, it stated it would take you back to stock. I just wasn't sure if it was meaning stock Inspire or stock Desire HD.

[Q] No data connection with any Jellybean ROMs

Hi,
I recently decided to flash a jeallybean ROM since most of them are getting really great and we don't have any word on the official update. Unfortunatly, I'm now unable to get a data connection on my HOX. It's the rogers version which I unlocked and I'm now using on the Bell network. Before flashing, LTE worked fine with the stock sense ROM, but now I don't have any data at all.
ROMs I've tried :
AOKP, MIUI and CM10.
I've tried to : set the data connection to GSM only, nothing, to LTE only, nothing, to WCDMA only, nothing. I've tried all the APNs I've found (pda.bell.ca, pda2.bell.ca, inet.bell.ca). On AOKP it sometimes said "Error while searching for network". WiFi, texts and calls work fine.
If anyone could help me, it would be really appreaciated. Otherwise I'll just revert to Rogers ROM. Thanks alot!
I cant offer any help, but I'm having a similar issue recently. I was on a nightly build of CM10 (from 10/06/12 I believe). I upgraded to a newer build (from 10/10) and I get no data over cell. I flashed it back and things were fine.

Before flashing jelly bean roms you need to flash a sense rom then do full wipe and install cm10 or aokp..

I have the exact same problem with my SGS using the X-bean 3.0 rom.
What's the best solution? Is it because I used to Cwm?

Every device has its own nuances, as do various ROMs. So I'd advise posting this in the forum specific to your device.
Still no data connection.
I am having the same issue with my AT&T One X phone.
The phone was running 2.20 before it was unlocked/rooted. Installed TWRP, was a noob and forgot to save a backup, fastbooted the boot.img, flashed AOKP and CM10 successfully. With both of these ROMs, I could not get internet to work via cellular connection. I have tried everything with the APNs (even had AT&T help me setup APN settings) and still no mobile data connection. I can still receive/send SMS/calls, use bluetooth and wifi, just no mobile internet.
I'm not entirely sure what to do next. I attempted to go back and flash the UrDroid 4.1 Stock Sense ROM, but after fastbooting it's boot.img and attempting to flash with TWRP, I got a signature verification failure. Got scared and restored back to AOKP (I remember to make a backup this time.)
Thoughts? Sorry for being a noob.
Are you in an LTE area?

I am in a "4G" area (HSPA+) but I am also a hour drive away from LTE. I have tried APNs for both, but AT&T recommended I stick to the LTE APN. AT&T had me go to Settings->More->Mobile Networks->Network Operators and the phone just sat there searching without finding anything. I just did that above operation again and it found AT&T and I selected it. It spins on "Registering on AT&T..." for a few minutes and eventually errors out "Cannot register on this network at this time."
Have you tried switching off LTE by selecting "GSM/WCDMA Auto" in Settings?
I've had data problems on certain ROMs, where turning off LTE got the HSPA+ connection working.
In that case, it was probably a base of build.prop not playing well with AT&T's network. Although I would think the ROMs you mentioned would have these issues worked out at this point (and for some time now).

When I switch to "GSM/WCDMA Auto", it immediately switches itself back to the LTE setting. This is concerning.

[Q] Flashing to stock - phone force closes process com.android.phone, help

Please bare with me since this is the first time having to post for an issue since I usually find an answer on your forums
So here's the situation.
I bought the photon q 4g lte from ebay and it came with the unlocked bootloader.
Needless to say it was with the stock ics and i tried to find a jellybean update because it wasn't taking the ota and ended up going with cyanogen since i had no problems before. However those phones i had before were with sim cards not cdma.
I found out i couldn't update prl or profile manually without having to do something on the pc.
So after searching left and right i found i could use rsl lite (I used 6.1.5) and eventually found the "stock" file from this post
http://forum.xda-developers.com/showthread.php?t=2095536&highlight=rsd+lite
I did the stock jellybean, got it to go through the process and it booted up with no errors.
However, when it boots into the os it pops up a force close on omadmclient_sprint_dataservice and eventually also on the process com.android.phone.
I tried putting it in airplane mode to see if the service error would go away but it didn't work for the process part crashing.
I tried re-flashing, deleting cache in recovery, doing a data/factory reset in recovery and the one time i was able to do a data factory reset within the settings menu.
I could not find anyone that said they had a rom that worked with sprint and updating prl within the rom, if anyone knows of one let me know and i will flash it through rsd.
Otherwise does anyone have an idea of what could be happening because googling the omadmclient part did not pull up anything specific and pulling up the process issue for other phones has not helped me either.
Was this a hacked GSM phone, or are you using it as CDMA?
I've never heard of people having FC issues after flashing a FXZ from RSD. Which one did you flash? Android 4.1.2 - Sprint US - 9.8.2Q-122_XT897_FFW-5 (No simlock) ?
If you are on stock, you should be able to update the PRL within the ROM.
I was trying to use it with cdma network through sprint. and yeah that was the file i downloaded, had to remove the getvar to get it working but flashed with no errors after doing that.
As for updating the prl i can barely navigate through the phone, there is no home page loading and the process pop comes up often enough that its hard to go through the settings

Sounds like something went wrong mate. Are you already activated on Sprint? I don't know if that would matter, it might.
I would honestly redownload and redo the RSD process.

I originally tried to activate the phone through cyanogen and then when the rep said he couldnt do it because of the lack of prl to update within the rom we just setup the activation back on the old phone/ That phone is working on the network.
I re-downloaded the file just in case and re-flashed but same problem. The only thing i thought of was maybe updating the radio but since its a stock rom it should work out of the gate. whats also weird is i tried turning wifi on but it didnt work either.
Anychange you know of a rom that works with sprint. I dont care if its stock since i would probably root later again.

Which one are you flashing?
Try another perhaps...? I honestly have never heard of this. It sounds like the phone might be damaged, or the RSD process just did not flash correctly.
I guess I should ask, was the phone modified at all for the GSM SIM slot mod? I wonder if having a non-Sprint SIM in is messing with it... That is just a shot in the dark.

so far the only rom i tried was 10.1 cyanogen and the stock rom for jellybean. However for the stock rom it doesnt let me downgrade to ics with rsd 6.1.5 do you think if i downloaded an old version i could downgrade to a lower stock rom?
Also I honestly had not looked for the cdma roms since most of what i saw was troubleshooting related for this phone but i just saw this rom -AOKP 4.2.2 (Android Open Kang Project) (CDMA&GSM) that you created - http://forum.xda-developers.com/showthread.php?t=2293892
I re-rooted and installed that one and it looks great, just wondered how you got sprint to activate the phone or if you had done it before changing the rom? Also how would the prl and profile be updated.
Lastly the wifi wasn't turning on this time either, it did work initially when i got the phone so that has me stumped.

To downgrade to ICS, you need to remove some additional lines. See this post for more information on that.
However, you should be able to update the PRL on either stock ROM.
I think I said this before, but I will say it again. You need to do PRL updates, activate the phone, and get EVERYTHING working on stock BEFORE you flash ANY custom ROM. This is just standard practice - you don't want to put the cart before the horse! Get the phone working, then play with custom ROM's.

mytouch 4g on ATT

Hi,
i have a used mytouch 4g which i rooted, s-off and gfree for my mom. she does not need data. i was able to pop in her att sim card and i had to manually select AT&T as a registered carrier. but every now and then, it would unregister itself and i would have to manually go into settings and select at&t again. i did this for my friend awhile back and it was fine for her. the only thing different is the rom. she was using CM7 and my mom is using slim bean 4.2.2. could it be the rom or did i mess something up while unlocking the phone? the phone had 2.3.4, and i had to downgrade before i can s-off and run gfree. though it looks like everything completed sucessfully, her phone keeps getting unregistered.
Try a different rom. I would recommend the last cyanogen nightly; or someone else had compiled a newer version of it.
If not try Stepps AOSPx; its a stable ICS.
Definitely ROM issue as I gave my glacier to a friend who has att and its on the double shot ROM with no problems

[Q] Turning a 4G Xoom to a Wifi Xoom

I have a 4G LTE Xoom that was on Verizon. I recently upgraded (now I have a Galaxy Note 10.1 2014 Edition), and my parents are buying my Xoom for use around the house on Wifi.
My question is: Can I just flash a Wifi Rom? Or will that mess up other things? Also, can/should I remove the LTE SIM card?
I know prior to BigPart, you could flash Wingray roms and get the what you're trying to achieve, but I did read that someone else tried that with the BigPart roms and got a whole slew of FCs that made the tablet unusable. I've currently suspended my tablet line through Big Red and I simply took my SIM card out. I get a warning any time I reboot about mobile data not working until a valid SIM card is installed, but if you ignore that, it functions perfectly otherwise.

I'll be honest: I haven't flashed a new ROM to my Xoom in a long time. It's currently running EOS Nightly 197 (Android 4.2.2) I had to look up what BigPart is, but I haven't installed anything like that. Would it be better if I do install Bigpart, and a Bigpart ROM? I think they can deal with pressing a "no SIM card" message on startup, but even on my current ROM, it's pretty laggy and slows down. Are Bigpart ROMs any better, or should I downgrade back to Honeycomb or something?

If your parents are like mine (read: not particularly tech-savvy), I'd probably just go back to stock JB. As much as I love the features of 4.4.2, you can't beat the stability and smoothness of 4.1.2 on this now-three-year-old tablet.
