Bootloop after changing SIM cards

Hi there folks!

I have a sort of specific problem here. I had NeatRom 6.4 on my i9100p for about a year, working perfectly. This year, when I went on vacation I changed my own SIM card with the local provider's SIM (for mobile data) and installed some settings sent from the local provider via MMS. Everything worked OK. Then after a week, when this account expired, I went back to the providers dealership, where they gave me another SIM card, but when we turned the phone off, put the new SIM in and turned the phone back on, it got in to a boot loop - the Galaxy logo shows up, then the neat rom logo turns for a few seconds and then it goes back to the galaxy logo. This goes on and on until I take out the battery. I tried leaving the phone without the battery for two days, tried again, same happens.

Now, I've found a lot of boot loop fixes, but I'm affraid to flash back to stock ROM (and I don't even want it) because my phone had the brick bug... Please, do any of you have any suggestions on what to do??

Thanks in advance!

An update:

I tried restoring my backup via PfilZ Touch 5 recovery but now its stuck at the SAMSUNG logo (it doesn't try to reboot to galaxy logo)...

Can someone clearup confusion

Hi, new here, I wish to flash Neatrom on an S2 and my confusion comes from the many, many tutorials on how to flash a custom ROM which have different references to PDA,Phone and CSC versions, so I´m stuck at what files to use to root my phone, what kernel to have and whether or not NeatRom can be flashed to my device.

Pressing *#1234# I get the following info:

PDA: I9100UHMS8

PHONE: I9100UHMS1

CSC: I9100AROMS4

Looking at about phone in settings I have

Android 4.1.2

Baseband: I9100UHMS1

Kernel:

3.0.31-914166

Problem restoring Jelly Bean 4.1.2 after installint NeatROM

hello there.

I have the International version of the Samsung Galaxy S2, i9100 and I have a bootloop problem after restoring JB since I installed Neatrom.

Here is a detailed report.

I had Jelly Bean 4.1.2 installed with Siyah Kernel S2-v6.0beta5.

Did a CWM backup and could do a restore as well.

Also had Cyanogenmod 10.1.3 installed and I could switch between JB and CM through backup and restore.

Then, I installed NeatROM I9100XWMS3_NeatROM_v6.4.zip (full version) and this was working fine.

Now, here it comes.

I made a CWM backup of NeatROM.

Then restored the JB backup after doing wipe cache/factory reset and wipe dalvik cache (I always do that before a restore).

Then I come in a bootloop.

Restoring the CynanogenMOD 10.1.3 backup works perfectly though.

After that , retried to restore the JB backup but got the bootloop again.

After searching on Internet I followed these steps:

Removed battery for 1 minute

Booted in Recovery Mode.

Wiped Dalvik Cache

Wiped Cache under Mounts & Storage

Rebooted and checked if bootloop disappears: no go.

Then I

Removed battery for 1 minute

Booted in Recovery Mode.

Wiped Dalvik Cache

Wiped Data under Mounts & Storage (this is called Format Cache and Format Data for me)

Wiped Cache under Mounts & Storage

Reboot and checked if bootloop disappears: no go

The backup of JB is not corrupted because I copied it over to another SD Card and the same problems happens with the original SD Card from which I was able to do the JB restore before I installed Neatrom.

I can't get rid of the bootloop.

What I don't understand is that I am able to restore the CM 10.1.3 backup.

I was able to flash the VOM-I9100XWLPD-20120514160325 stock ROM, which gives me ICS 4.0.3.

This is nice to see again but I want the JB 4.1.2 Stock ROM.

So I connected the phone to Kies but Kies does not let me update the Android version. Or am I missing something there????

So I flashed the I9100XWMS1_I9100NEELS1_NEE but this also remains in a boot loop.

Any ideas to solve this? it seems like my phone does not like Jelly Bean 4.1.2 anymore, even after flashing the stock ROM.

Many thanks for your help or explanation.

regards

[Galaxy S II Q&A, Help & Troubleshooting] Saber:
You should be able to flash the rom again to restore bootanimation without wiping.

Root

Sorry to be offtopic, but Kingo ROOT is working for Lenovo VIBE Z2 Pro
[Lenovo K900] wonderbao:
Hi Majrul. Do you have this phone? I'm considering buying it. Can you give a quick first impressions?

Thanks.
[Lenovo K900] wonderbao:
Thanks for the review, rdosti.

I have a few questions I hope you can answer.

Have you rooted your phone? If yes, did you use the Kingo app?

Do the phone have any heat issues?

I heard that it can be difficult to install new apps because of the security app that comes preinstalled. Do you have the same experience?

I will receive my phone in a coupe of weeks. Can't wait!
[Lenovo K900] rdosti:
Why would you root the phone? --- You get stock rom (android) included as an option. You need to enable it through Developer Options in Settings (and you can reboot the phone in Stock android GUI).

No over heating issues have been experienced.

No issues installing Apps. Not sure what Security App you are talking about. Are you referring to "Secure Zone" which is already available on most android smart devices which allows you to separate business and home apps and screens?

"In Vibe Z2 Pro, we have two zones: open zone and secure zone. Every app can be run in open zone while only trusted app will be run in secure zone to protect sensitive application & data for user. User can easily switch between open zone and secure zone by only "one click". In secure zone, it is safer, freer and easier."

Thanks: additional question

Thanks:

1. whether we can install & run apps from OTG devices

2. MHL support is not mentioned, is it a software option later can be tweaked

3. DUAL sim 3G/4G is it an software tweakable option

4. who is the winner among IUNI 3, K920 & 64 bit VIBE Z2

5. how is lenovo after sales support, i am ****** with micromax service with A210 [very poor service]

6. is there a promise for Android L or cyanogen mod!

is there a phone you suggest with dual GSM sim, removable battery, 2-3GB RAM, 13+ BSI, dual LED, future ready performer at least FHD 5inch
[Lenovo K900] rdosti:
Hi will try to answer as many as I can.

- I am getting my OTG Flash Drive today so will be able to let you know by tomorrow.

- Micro USB to HDMI should work.

- Dual SIM (SIM Slot one is for 4g/3g/2gb & SIM Slot two is for 2G). By the way I am impressed that both SIMS go into a single tray which has been made so you can fit two sim cards. Excellent design. Sadly second slot is clearly marked for only 2G.

- Vibe Z2 Pro stands out in all my tests

- I have been lucky enough never to need it. I think support of all companies except Apple "suck". Apple's replacement system is unbeatable.

- Lenovo have said that their flagship will get updates - however I will take that with a pinch of salt since there is no guarantees on that.

One of the things I was depressed about was the Camera is not as great as I would have hoped or imagined. Though many reviewers have said it is great, I took photos this morning in day light as well as night time and minor zooming of the photos taken already, were quite grainy. In my opinion the camera is a let down.

I would suggest the Z2 Pro which is quite reasonably priced. The lack of marketing and brand ambassadors have allowed them to allow them to price themselves at a fairly competitive price. The only single sim competitor is the Nexus which is speculated to be announced tomorrow. There is no dual sim competitor worth comparing this device too at this price point.

---------- Post added at 11:03 AM ---------- Previous post was at 10:58 AM ----------

By the way - Regarding the secure app - You can force stop and disable it. I did just that. There is an inbuilt antivirus which got the same treatment from me. Those memory hogging antivirus do nothing and waste valuable resources in my opinion. Force Stop - Disable is the way to go !

I also removed some apps and games I wasn't planning to use to free up some space on the phone.

I was able to easily get 1.5 GB Free RAM (out of 3 GB) which is one of the best performing devices I have seen. That allows me to load and run high end QHD videos as well as Games without worrying about RAM issues or lack of available RAM. 50% RAM free is like a God Send for people who really want to take it on for gaming!

I had around 24-25 GB of free internal storage immediately, which gives me quite a lot of space to fill up with things I need or want. OTG always remains a second option.

MY recommendation is load all your apps on the internal storage for faster "read" speeds, and put all your media on the OTG flash drives or any free space left on your internal storage.

I would not recommend apps being put on OTG for a very simple reason, you will find a lag or a every so tiny lag which reduces the fun of having such a beautiful device.

The Brightness makes the Nexus 5 look like crap!
[Lenovo K900] Photoneutron:
Thanks a lot for your time & strouble.

I am in a dilemma whether to wait for MTK 6595 [vibe X2] or MTK 6795 phones? or to go for 64 bit Snapdragon?
[Lenovo K900] viruscmotu:
Thanks for your review man, Really appreciate it.

1.). I would like to know specifically in the Google UI Mode, is the sercurity app(I mean the Antivirus App and NOT the Secure Mode App) still installed and running ?

Is it possible to disable and force stop them? Because in whatever little videos i have seen on-line, most have the security app in the Notification drawer which is kinda annoying and

frustrating? Also i read somewhere that the Lenovo Antivirus App(Security App) is soo ingrained in the OS that it starts to mess around with whatsapp and other Apps when Disabled

or Force stopped and it re enables itself after sometime.

2.). Also how much ram usage in Google UI mode?

3.). Does the phone feel less bloated and snappier when in Google UI mode?

4.). Any particular features you feel are missing in the Google UI Mode that are there in the Vibe UI mode?

5.). Would you root the Phone to remove all the unnecessary apps like the Security app , Secure zone, SyncIT, ShareIT apps and all the other useless apps?

Sorry , Too many questions. :confused:
[Lenovo K900] rdosti:
If this is any motivation Z2 Pro just released a stability update today of 60 MB.

K920_ROW_S133_141010

Gives you an idea that they are updating things.
[Lenovo K900] rdosti:
To viruscmotu -

1. You can disable (force stop and disable) the app. I did that the moment I got my device.

2. Surprisingly and sadly, the free RAM is almost the same in both UI's which begs the question - WHY ? I actually began to like Lenovo's UI by the way - its kind of like the iPhone - everything's on the home screens + Widgets! I have already mentioned in previous posting's you get around 1.5 GB Free RAM.

3. Google UI mode feels only a very tiny bit (very cautious) faster. I think the Google UI mode has been tweaked by Lenovo since many minor but catchable things are not "true stock".

4. Yes, there is one feature which I think is extremely shocking not there in Google UI - The "OTA Update" feature. This has got me really disturbed about the device. I have to reboot back into Vibe UI to actually look for any new update (we got one last night ) which I would have missed had I stayed in the Google UI permanently.

5. Honestly, I don't see any reason to remove it since it doesn't take up too much space and you can easily disable it. It does not pop up or bother you ever again. Without root you can perform most of the disable actions and if you just want to be sure - you can download "Clean Master" - a free ware and very popular app to disable those preinstalled apps you wish to.

Regarding the question whether to wait for the X2 , etc... The snapdragon is a way better chipset in all reality that any others seen today. The Note 4 and Nexus 6 run on Snapdragon 805 (latest) , though the LG3 and this device run on 801 (which is in my opinion fairly great too).

I would personally not move to any device that is not snapdragon.
[Lenovo K900] hobitt14:
Stupid question?

Hello rdosti,

I've been reading this thread about Vibe Z2 Pro, as it looks to be my next phone (hopefully). I have it already pre-ordered, but I am still waiting, as it is not so easy to get on of those devices.

Perhaps this would be a stupid question, but I thought that as you have "stock" android version on the Vibe Z2 Pro, that for example update for Android 5.0 would be pretty straightforward. Can you confirm / decline / comment on that?

I have been using WinPhone for quite some time ,but I've got pretty bored with the lack of the applications in WP store, si I am looking to switch to Android. This Phone would suit me perfectly as it has everything that I need.

Only thing that keeps me hesitating is this Stock / Lenovo version of Android and prospect of new Android upgrades in the upcoming time. :)

Many thanks for the update &

My best regards

[Lenovo K900] rdosti:
You have to wait till Lenovo offers an update for Lolipop (Android L). Its still a Lenovo ROM at the end of the day.

Only the Android One phones and Nexus devices are offered immediate upgrades to the new Android OS.

No other phone no matter what ROM its on gets an immediate upgrade. You need to wait patiently ;)
[Lenovo K900] vince_junior:
O my god! I am so glad that i found this thread! Ive been in the fence whether to buy vibe z2 pro or mate 7. But after reading this, this made me choose the z2.pro.

Thanks rdosti for your review and answering the questions!

Just one question, rdosti. In the reviews i saw at youtube, i cant help but notice that the lenovo ui in the vibe z2 pro is not that snappy. Is that really the case?
[Lenovo K900] hobitt14:
....

Thank you for the answer rdosti.

So it means, taht it is nice that phone have stock android, but still Lenovo has to make upgrade for newer versions of OS.

For the price, they are asking for this device it is still worth to buy it, since Nexus 6 is much more expensive.

You personally thinks that software upgrade will be available for this device in the future? as I am not that familiar with Lenovo phones, I do have Lenovo laptop and I am more then happy with it.

I heard some rumours about overheating of the device on the internet, and also some complains about software buggs, like wallpapers disappearing, screen lock is not working, random factory resets and so on. Is this true? Any comments on that? :)

Sorry for being pesky and asking a lot of questions, but I was not able to find any review on the web (neither from my country - SVK nor international). Phone was introduced in my country just recently, I mean like 12 days ago.

Thank you &

Best regards.

While in the stock UI, Will the lenovo camera app be available? Or will it be the stock camera app with very basic functionality?
[Lenovo K900] Rutz272:
Hello, I have this phone for more than a week. I can answer some of your questions.

hobitt14: The Vibe UI feels great, not bloated but with a lot of additional useful settings. I did NOT notice any lag or overheating.

sacthegreat: There is Lenovo camera app available in the stock UI.

The phone feels great. Love the thin bezels and metallic brushed-wave unibody design. It's really thin and the display is gorgeus. My previous phone was Samsung Galaxy Note 2 and I was deciding between VIBE Z2 Pro and Galaxy Note 4.

About cell broadcasting messages bug. I have tried the method mentioned here http://forum.cyanogenmod.org/topic/79524-permanently-bockdisable-cell-broadcast/

It didn't work

Then i installed noboat free app. Tried disabling from that which didn't work.

Then i deleted the cell broadcasting apk. It didn't work. It removed the settings for them though.

Now only thing remains to be do is to delete the stock sms app.

There was a major problem with mine - so returned it.. but now, thinking to purchase it back since I'm not able to find a better phone than this!
[Lenovo K900] lockhrt999:
Guys good news, I took care of both bugs,

# 1. cell message broadcasting

#2. vibration is turned off whenever you come back to general audio profile from say vibration audio profile.

It's simple to remove, just switch to secure zone and turn off settings of cell broadcasting messages. For audio profile, it's not available in settings so access them by pressing and holding on the audio profile icon from notification panel. Toggle between off and then on so it saves into memory. [originally suggested by Spariant]

[MENTION=4135646]sacthegreat[/MENTION]: No network issues. But on an average I have found this mobile receives a little less range compared to moto e (I checked). However moto e had only single sim whereas z2 pro always carry two sims so maybe it has to do something with that. There is one thing I have found which, when I'm on a call, the signal is boosted automatically. This mobile also suffers from 'you're holding it wrong' problem. Signal is dropped by 10-20% when you are holding it in a certain way so obviously not as bad as iphone 4. Anyway I haven't found a single mobile which didn't face that issue. Wifi signal drop is prominent especially when you're holding the phone horizontally say while gaming and you're on the edge of the wifi coverage, it'll probably disconnect because your left hand fingers generally obscure the wifi antenna.

Lastly, I have never faced any call drop issue.
[Lenovo K900] sacthegreat:
