[HTC Rezound] Anseri:
I currently have my rezound unlocked and s-off with a straight talk att sim card, running liquid rom (most current). I have used CDMA workshop to edit nv values that would supposedly get 3g working (no-go). At no point since I have had the rezound on straight talk (even before nv edits) have I been able to send or receive sms, or receive phone calls. I can make outgoing calls and have edge data. I've tried fifty different ROMs and as many or more different "3g fix" hacks, to no avail. I have used probably over 100 different APN settings as well. I am (slowly) downloading all the files I need for a complete downgrade and update (my rez is my only source of internet right now), in hopes that doing that may have some influence in getting things working properly.

Edit: Forgot the most important part, if anyone has any thing that they think may work, please share. I'm willing to try anything at least once.

Bump
[HTC Rezound] Aly3n:
I think the bands are the problem so no software can fix hardware problems
[HTC Rezound] Anseri:
I don't think you read my entire post. In not really concerned with data speed, what I want is SMS, MMS, and to recurrence phone calls. Which it should be able to do without any modification.
[HTC Rezound] Aly3n:
Just flash this

internauta37(dot)altervista(dot)org/how-and-patch-fully-enable-gsm-verizon-cdma-phones-android

If on "stock ROM" it should work without if on other ROM flash this if it doesnt connect automaticly let it sit for a while if it still doesn't reflash
[HTC Rezound] acejavelin:
Are you on AT&T or T-Mobile StraightTalk? Have you tried the SIM in another device? The reason I ask is because if you can make an outbound call and get Edge data, that is all you really you need to receive a call and send/receive SMS. MMS is a little more complicated but until you can get the voice and SMS working, I wouldn't even worry about MMS. But I am going to be honest, this sounds more like a SIM or Straight Talk setup issue than a phone issue.

[MENTION=5037435]REV3NT3CH[/MENTION] is kind of the expert in using domestic GSM on the Rezound... maybe he can chime in a little bit on this.
[HTC Rezound] Aly3n:
Sorry I copied and paste that from another thread
[HTC Rezound] Anseri:
I'll try this when I get home.

At&t sim
[HTC Rezound] Anseri:
I'll flash this when I get home. Thanks.

At&t sim.
[HTC Rezound] Anseri:
I'll try this when I get home. Thanks
[HTC Rezound] Aly3n:
Luck?
[HTC Rezound] acejavelin:
I am not sure I understand why all this is necessary... there are two simple prop.build tweaks that need to be done to get GSM to work reliably with most JB/KK ROMs, if you look in the first or second post of ROMs like Vanir and Evervolv you will see a GSM.zip that you can flash to make these changes for you, some newer ROMs make these changes for you on the fly (or so it appears, I do not have a Rezound any longer). This is typically all that is required to make it work, although some NV edits might be needed to tune the radios for better reception, it should have basic functionality with minimal changes.

Make sure you on the latest Hboot and radios, wipe thoroughly, and flash per dev's instructions and look through your ROM thread for any GSM specific settings or changes that need to be made (if you can't find any, ask in the ROM thread to be sure).

I have to go back to wondering if you tested this in a AT&T phone to make sure it works, because this sure sounds like a SIM or activation issue with Straight Talk to me.
[HTC Rezound] Anseri:
It may very well be an issue with straight talk. I used the att sim from their byop kit and don't have an att phone to test it on. I'm still trying to get all of the files downloaded to do a full factory restore to make sure it's not something in my device that's the issue.
[HTC Rezound] Anseri:
I have downloaded the file, but still haven't gotten a chance to flash. I'll update here as son as I get a chance.
[HTC Rezound] Anseri:
So I tried about three different gsm fix zips, including the one Aly3n posted. None of them worked. I have only two options left. Full factory downgrade and restore, and calling straight talk to see what they have to say.
[HTC Rezound] acejavelin:
Did you dirty flash your ROM between each GSM patch flash? If not you didn't have a good starting point for each attempt because your system partition had been modified with each flash...
[HTC Rezound] Anseri:
Clean flash every time.
[HTC Rezound] acejavelin:
I would try to find an AT&T phone to test your SIM... I am betting this is a ST issue
[HTC Rezound] Aly3n:
Have let it sit for a while
[HTC Rezound] Anseri:
Let it sit long enough to connect to data and make a phone call.

On another note, I can send and receive SMS from a friend of mine an I'm unit (national guard), but I can't SMS or MMS with my wife. *shrug*

Edit: I can also receive automated SMS from straight talk. This is all with no change to the setup I had when I first posted.
[HTC Rezound] Anseri:
My wife just discovered that she can text me with my phone number@txt.att.net and I can text her at her number@vtext.com

This leads me to believe I have APN problems? Maybe.
[HTC Rezound] acejavelin:
SMS is not dependent on APN settings, this points to a Straight Talk issue... Sorry... To be honest the best fix is usually to get a new SIM. I would honestly recommend porting out to Cricket or Go Phone.

are you sure because the partition and the kernal are different it might work in the graphical way but can you backup and most importantly restore be carefull might brick your device if you check please tell soon......will be very greatfull as i also have a LenovoA3500-HV
[Lenovo A3500 Guides, News, & Discussion] sanguinevn:
It was actually risky to try this root method for my aunt's A3500 HV as I had just bought it for her on 24 Sep 2014.

Originally I bought the tablet with android 4.2.2 and it was get rooted by RootGenius__lenovohome v 1.9.6. When I found this thread, I updated the tablet into FW version A3500hv_a442_01_32_140805 (android 4.4.2) by flashing tool. When it was successful updated to this version, I was noticed via OTA a newer version, FW A3500-HV_A442_01_35_140911 immediately after the first boot. I went ahead with downloading and updating the newer version by OTA. I felt it was so much better with the latest version with rapid lock GPS, better screen display quality and better sound quality as well.

As I was afraid to get brick the tablet in this thread, I tried to root the tablet again with RootGenius__lenovohome v 1.9.6 again but no lucky. As the result I decided to give me a chance to try the root method in this thread for A3500 HV with my own risk as I thought it can be unbrick by re-flashing a FW. Luckily it was rooted successfully with the instruction in this thread. It was a magic. :good::good::good:

There you go some screenshots.
[Lenovo A3500 Guides, News, & Discussion] sanguinevn:
I don't own this device unfortunately. Sorry.
[Lenovo A3500 Guides, News, & Discussion] anandisrocking007:
Thanks for the reply well I new that they had put some extra security in the new kitkat version so that you can not root but when you use the recovery then you are installing the su file when android OS is is off so the security can't catch you

All right one last question have you tried making a nandroid backup and restoring it up until now if so and successfully please say so

Also if you do not know what a nandroid backup is it is just a backup of an entire operating system and can be used if the system gets bricked and it is totally harmless all it takes is 5 min since you had done the dangerous part and if that works can you check out nandroid restore because if the backup worked in success then there is a 97% chance that clockworkmod restore works o and there won't be any loss of data because you are doing a restore of all the data you backed up seconds ago

If there is a single error message after even after the backup and restore is finished please report it

The backup is totally harmless so if you can just check that I and all the HV version around the world would be very great full thanks in advance.......:fingers-crossed:
[Lenovo A3500 Guides, News, & Discussion] sanguinevn:
Actually I'm pretty sure that KK FW of A3500H does work on A3500HV then I think that the root method will work on A3500HV either. The only different thing between A3500H and A3500HV is call function, I think so.

I did try a Nandroid backup on FW 4.2.2 actually by using the recovery in this thread before upgrading to KK FW. It took about 10 minutes less for the backup procedure to be done without any error and it was written on CMW/BACKUP folder on external SD card (16GB was used). I noticed that the backup steps were similar to any Nandroid backup on CWM recovery: backup boot, recovery, system then data... later generating MD5 checksum. I haven't tried to restore this backup as the update KK FW works really great.

I also tried to flash zip FW (the latest one with build number ​ A3500-HV_A442_01_35_140911) which was found on this link https://yadi.sk/d/KY44k2XDba5Mw from the Russian Lenovo Forum when the tablet was on FW 4.2.2. However, it was not successfull as the recovery said that there was nothing found on the zip to flash. I had no idea about it. Maybe we cannot upgrade to KK by this way when on JB FW or this CWM recovery (which is customized for A3500) can't be used to flash rom. Then I have to upgrade it by flashing tool and FW found on this link: http://lenovo-forums.ru/topic/7809-прошивка-lenovo-a7-a3500hv-a442-01-32-140805-row-call/

Link to the forum: http://lenovo-forums.ru/forum/289-прошивки-lenovo-a7-a3500/

The tablet is not with me now as I just bought it for my aunt so I don't have a chance to try Nandorid backup when it is on KK FW. If there is a chance to do so, I will report it shortly.

I think it would be great if we could have flashable custom rom for Lenovo A3500HV via offical custom recovery.

Good luck!

Cheers,

By the way:

I successfully run a Lenovo a7 40 a3500-fl with twrp 3.0.2 and RessurectionRemix 5.7.4 (final marshmallow build) which is fast, smooth and stable - especially compared to the stock Kitkat Rom, this solution makes the device feel almost new and kept me from buying a new one the last year...

Here's a link of RessurectionRemix 5.7.4 (G-drive) which I'm using and 2 others which I consider to be the most stable ones and definitely daily driver material at the time I'm writing, with about 7 or 8 different ROMs in total, it's working for the whole lenovo a7 40 a3500 (F/FL/H/HV, etc.) family, declared H/HV version have RIL (Telephony) working when F/FL versions have not as these models are WiFi variants, you can change the build.prop to display the the correct model cause this will show lenovo a7 a7 40 a3500-fl (or any different version from yours), it's just a cosmetic... :) also unwanted telephone settings on a Wi-Fi tablet can be hidden with Xposed Framework and a module called "settings editor", which works really nicely...

For volume level being to loud flash this in recovery:

Audio_Fix/android 6

This device has a unlocked bootloader by default, so the easy way is to use kingroot to gain root privileges, then install flashify or rashr for Playstore to flash the TWRP image, after that boot to recovery by pressing and holding power and volume up & down simultaneously - now in TWRP do backup EVERY partition (especially NVRAM), wipe everything but internal storage and flash rom and Gapps (according to the device architecture)... This method works without a PC, alternatively the method described by OP can be used :)
